The National Aeronautics and Space Administration Orion Flight Test Office was tasked with conducting a series of flight tests in several launch abort scenarios to certify that the Orion Launch Abort System is capable of delivering astronauts aboard the Orion Crew Module to a safe environment, away from a failed booster. The first of this series was the Orion Pad Abort 1 Flight-Test Vehicle, which was successfully flown on May 6, 2010 at the White Sands Missile Range in New Mexico. This report provides a brief overview of the three propulsive subsystems used on the Pad Abort 1 Flight-Test Vehicle. An overview of the propulsive systems originally planned for future flight-test vehicles is also provided, which also includes the cold gas Reaction Control System within the Crew Module, and the Peacekeeper first stage rocket motor encased within the Abort Test Booster aeroshell. Although the Constellation program has been cancelled and the operational role of the Orion spacecraft has significantly evolved, lessons learned from Pad Abort 1 and the other flight-test vehicles could certainly contribute to the vehicle architecture of many future human-rated space launch vehicles
The Max Launch Abort System - Concept, Flight Test, and Evolution
Gilbert, Michael G.
2014-01-01
The NASA Engineering and Safety Center (NESC) is an independent engineering analysis and test organization providing support across the range of NASA programs. In 2007 NASA was developing the launch escape system for the Orion spacecraft that was evolved from the traditional tower-configuration escape systems used for the historic Mercury and Apollo spacecraft. The NESC was tasked, as a programmatic risk-reduction effort to develop and flight test an alternative to the Orion baseline escape system concept. This project became known as the Max Launch Abort System (MLAS), named in honor of Maxime Faget, the developer of the original Mercury escape system. Over the course of approximately two years the NESC performed conceptual and tradeoff analyses, designed and built full-scale flight test hardware, and conducted a flight test demonstration in July 2009. Since the flight test, the NESC has continued to further develop and refine the MLAS concept.

The National Aeronautics and Space Administration Engineering and Safety Center designed, developed and flew the alternative Max Launch Abort System (MLAS) as risk mitigation for the baseline Orion spacecraft launch abort system already in development. The NESC was tasked with both formulating a conceptual objective system design of this alternative MLAS as well as demonstrating this concept with a simulated pad abort flight test. Less than 2 years after Project start the MLAS simulated pad abort flight test was successfully conducted from Wallops Island on July 8, 2009. The entire flight test duration was 88 seconds during which time multiple staging events were performed and nine separate critically timed parachute deployments occurred as scheduled. This paper provides an overview of the guidance navigation and control technical approaches employed on this rapid prototyping activity; describes the methodology used to design the MLAS flight test vehicle; and lessons that were learned during this rapid prototyping project are also summarized.

The National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) was tasked to develop an alternate, tower-less launch abort system (LAS) as risk mitigation for the Orion Project. The successful pad abort flight demonstration test in July 2009 of the "Max" launch abort system (MLAS) provided data critical to the design of future LASs, while demonstrating the Agency s ability to rapidly design, build and fly full-scale hardware at minimal cost in a "virtual" work environment. Limited funding and an aggressive schedule presented a challenge for testing of the complex MLAS system. The successful pad abort flight demonstration test was attributed to the project s systems engineering and integration process, which included: a concise definition of, and an adherence to, flight test objectives; a solid operational concept; well defined performance requirements, and a test program tailored to reducing the highest flight test risks. The testing ranged from wind tunnel validation of computational fluid dynamic simulations to component ground tests of the highest risk subsystems. This paper provides an overview of the testing/risk management approach and methodologies used to understand and reduce the areas of highest risk - resulting in a successful flight demonstration test.
Onboard Determination of Vehicle Glide Capability for Shuttle Abort Flight Managment (SAFM)
Straube, Timothy; Jackson, Mark; Fill, Thomas; Nemeth, Scott
2002-01-01
When one or more main engines fail during ascent, the flight crew of the Space Shuttle must make several critical decisions and accurately perform a series of abort procedures. One of the most important decisions for many aborts is the selection ofa landing site. Several factors influence the ability to reach a landing site, including the spacecraft point of atmospheric entry, the energy state at atmospheric entry, the vehicle glide capability from that energy state, and whether one or more suitable landing sites are within the glide capability. Energy assessment is further complicated by the fact that phugoid oscillations in total energy influence glide capability. Once the glide capability is known, the crew must select the "best" site option based upon glide capability and landing site conditions and facilities. Since most of these factors cannot currently be assessed by the crew in flight, extensive planning is required prior to each mission to script a variety of procedures based upon spacecraft velocity at the point of engine failure (or failures). The results of this preflight planning are expressed in tables and diagrams on mission-specific cockpit checklists. Crew checklist procedures involve leafing through several pages of instructions and navigating a decision tree for site selection and flight procedures - all during a time critical abort situation. With the advent of the Cockpit Avionics Upgrade (CAU), the Shuttle will have increased on-board computational power to help alleviate crew workload during aborts and provide valuable situational awareness during nominal operations. One application baselined for the CAU computers is Shuttle Abort Flight Management (SAFM), whose requirements have been designed and prototyped. The SAFM application includes powered and glided flight algorithms. This paper describes the glided flight algorithm which is dispatched by SAFM to determine the vehicle glide capability and make recommendations to the crew for site

A 6%-scale unpowered model of the Orion Launch Abort Vehicle (LAV) ALAS-11-rev3c configuration was tested in the NASA Langley National Transonic Facility to obtain static aerodynamic data at flight Reynolds numbers. Subsonic and transonic data were obtained for Mach numbers between 0.3 and 0.95 for angles of attack from -4 to +22 degrees and angles of sideslip from -10 to +10 degrees. Data were also obtained at various intermediate Reynolds numbers between 2.5 million and 45 million depending on Mach number in order to examine the effects of Reynolds number on the vehicle. Force and moment data were obtained using a 6-component strain gauge balance that operated both at warm temperatures (+120 . F) and cryogenic temperatures (-250 . F). Surface pressure data were obtained with electronically scanned pressure units housed in heated enclosures designed to survive cryogenic temperatures. Data obtained during the 3-week test entry were used to support development of the LAV aerodynamic database and to support computational fluid dynamics code validation. Furthermore, one of the outcomes of the test was the reduction of database uncertainty on axial force coefficient for the static unpowered LAV. This was accomplished as a result of good data repeatability throughout the test and because of decreased uncertainty on scaling wind tunnel data to flight.
Orion Pad Abort 1 Crew Module Inertia Test Approach and Results
Herrera, Claudia; Harding, Adam
2010-01-01
The Flight Loads Laboratory at the Dryden Flight Research Center conducted tests to measure the inertia properties of the Orion Pad Abort 1 (PA-1) Crew Module. These measurements were taken to validate analytical predictions of the inertia properties of the vehicle and assist in reducing uncertainty for derived aero performance results calculated post launch. The first test conducted was to determine the Ixx of the Crew Module. This test approach used a modified torsion pendulum test step up that allowed the suspended Crew Module to rotate about the x axis. The second test used a different approach to measure both the Iyy and Izz properties. This test used a Knife Edge fixture that allowed small rotation of the Crew Module about the y and z axes. Discussions of the techniques and equations used to accomplish each test are presented. Comparisons with the predicted values used for the final flight calculations are made. Problem areas, with explanations and recommendations where available, are addressed. Finally, an evaluation of the value and success of these techniques to measure the moments of inertia of the Crew Module is provided.

In order to mitigate catastrophic failures on future generation space vehicles, engineers at the National Aeronautics and Space Administration have begun to integrate a novel crew abort systems that could pull a crew module away in case of an emergency at the launch pad or during ascent. The Max Launch Abort System (MLAS) is a recent test vehicle that was designed as an alternative to the baseline Orion Launch Abort System (LAS) to demonstrate the performance of a "tower-less" LAS configuration under abort conditions. The MLAS II test vehicle will execute a propulsive coast stabilization maneuver during abort to control the vehicles trajectory and thrust. To accomplish this, the spacecraft will integrate an Attitude Control System (ACS) with eight hypergolic monomethyl hydrazine liquid propulsion engines that are capable of operating in a quick pulsing mode. Two main elements of the ACS include a propellant distribution subsystem and a pressurization subsystem to regulate the flow of pressurized gas to the propellant tanks and the engines. The CAD assembly of the Attitude Control System (ACS) was configured and integrated into the Launch Abort Vehicle (LAV) design. A dynamic random vibration analysis was conducted on the Main Propulsion System (MPS) helium pressurization panels to assess the response of the panel and its components under increased gravitational acceleration loads during flight. The results indicated that the panels fundamental and natural frequencies were farther from the maximum Acceleration Spectral Density (ASD) vibrations which were in the range of 150-300 Hz. These values will direct how the components will be packaged in the vehicle to reduce the effects high gravitational loads.

Abort trajectory is a passage that ensures the astronauts to return safely to the earth when an emergency occurs. Firstly,the essential elements of mission abort are analyzed entirely based on summarizing the existing studies. Then,abort trajectory requirement and rational selection for different flight phases of typical manned lunar mission are discussed specifically. Considering a trade-off between the two primary constrains of an abort,the return time of flight and energy requirement,a general optimizing method for mission abort is proposed. Finally,some suggestions are given for China’s future manned lunar landing mission.
PIV Measurements of the CEV Hot Abort Motor Plume for CFD Validation
Wernet, Mark; Wolter, John D.; Locke, Randy; Wroblewski, Adam; Childs, Robert; Nelson, Andrea
2010-01-01
NASA s next manned launch platform for missions to the moon and Mars are the Orion and Ares systems. Many critical aspects of the launch system performance are being verified using computational fluid dynamics (CFD) predictions. The Orion Launch Abort Vehicle (LAV) consists of a tower mounted tractor rocket tasked with carrying the Crew Module (CM) safely away from the launch vehicle in the event of a catastrophic failure during the vehicle s ascent. Some of the predictions involving the launch abort system flow fields produced conflicting results, which required further investigation through ground test experiments. Ground tests were performed to acquire data from a hot supersonic jet in cross-flow for the purpose of validating CFD turbulence modeling relevant to the Orion Launch Abort Vehicle (LAV). Both 2-component axial plane Particle Image Velocimetry (PIV) and 3-component cross-stream Stereo Particle Image Velocimetry (SPIV) measurements were obtained on a model of an Abort Motor (AM). Actual flight conditions could not be simulated on the ground, so the highest temperature and pressure conditions that could be safely used in the test facility (nozzle pressure ratio 28.5 and a nozzle temperature ratio of 3) were used for the validation tests. These conditions are significantly different from those of the flight vehicle, but were sufficiently high enough to begin addressing turbulence modeling issues that predicated the need for the validation tests.
Testing the Perturbation Sensitivity of Abortion-Crime Regressions
Directory of Open Access Journals (Sweden)
Michał Brzeziński
2012-06-01
Full Text Available The hypothesis that the legalisation of abortion contributed significantly to the reduction of crime in the United States in 1990s is one of the most prominent ideas from the recent “economics-made-fun” movement sparked by the book Freakonomics. This paper expands on the existing literature about the computational stability of abortion-crime regressions by testing the sensitivity of coefficients’ estimates to small amounts of data perturbation. In contrast to previous studies, we use a new data set on crime correlates for each of the US states, the original model specifica-tion and estimation methodology, and an improved data perturbation algorithm. We find that the coefficients’ estimates in abortion-crime regressions are not computationally stable and, therefore, are unreliable.

After the first encouraging tests performed in 2009, machine time was allocated in 2010 to continue the commissioning of the abort gap cleaning systems. This note summarises the test performed in October 2010 at 450 GeV, using the vertical damper system in order to clean the particles located in the abort gap. The results showed that the particle population was indeed cleaned, without affecting in a measurable way the emittance of the bunches which were immediately adjacent to the abort gap. The system was declared operational and is now used with the LHC at injection energy.

Following the abort gap cleaning tests performed on 7 October 2011 [1] additional tests were carried out on 13 October 2011 to further investigate the effects of the cleaning on the luminosity production. The abort gap cleaning parameters (strength and duration of the beam excitation kick) were varied and the cleaning effectiveness measured together with the change in luminosity. The outcome is summarised in this note.
Gain Scheduling for the Orion Launch Abort Vehicle Controller
McNamara, Sara J.; Restrepo, Carolina I.; Madsen, Jennifer M.; Medina, Edgar A.; Proud, Ryan W.; Whitley, Ryan J.
2011-01-01
One of NASAs challenges for the Orion vehicle is the control system design for the Launch Abort Vehicle (LAV), which is required to abort safely at any time during the atmospheric ascent portion of ight. The focus of this paper is the gain design and scheduling process for a controller that covers the wide range of vehicle configurations and flight conditions experienced during the full envelope of potential abort trajectories from the pad to exo-atmospheric flight. Several factors are taken into account in the automation process for tuning the gains including the abort effectors, the environmental changes and the autopilot modes. Gain scheduling is accomplished using a linear quadratic regulator (LQR) approach for the decoupled, simplified linear model throughout the operational envelope in time, altitude and Mach number. The derived gains are then implemented into the full linear model for controller requirement validation. Finally, the gains are tested and evaluated in a non-linear simulation using the vehicles ight software to ensure performance requirements are met. An overview of the LAV controller design and a description of the linear plant models are presented. Examples of the most significant challenges with the automation of the gain tuning process are then discussed. In conclusion, the paper will consider the lessons learned through out the process, especially in regards to automation, and examine the usefulness of the gain scheduling tool and process developed as applicable to non-Orion vehicles.
Crew Exploration Vehicle Launch Abort Controller Performance Analysis
Sparks, Dean W., Jr.; Raney, David L.
2007-01-01
This paper covers the simulation and evaluation of a controller design for the Crew Module (CM) Launch Abort System (LAS), to measure its ability to meet the abort performance requirements. The controller used in this study is a hybrid design, including features developed by the Government and the Contractor. Testing is done using two separate 6-degree-of-freedom (DOF) computer simulation implementations of the LAS/CM throughout the ascent trajectory: 1) executing a series of abort simulations along a nominal trajectory for the nominal LAS/CM system; and 2) using a series of Monte Carlo runs with perturbed initial flight conditions and perturbed system parameters. The performance of the controller is evaluated against a set of criteria, which is based upon the current functional requirements of the LAS. Preliminary analysis indicates that the performance of the present controller meets (with the exception of a few cases) the evaluation criteria mentioned above.

A detailed performance evaluation of the Abort Region Determinator (ARD) module design was provided in support of OFT-1 ascent and OFT-1 intact launch aborts. The evaluation method used compared ARD results against results obtained using the full-up Space Vehicle Dynamic Simulations program under the same conditions. Results were presented for each of the three major ARD math models: (1) the ascent numerical integrator; (2) the mass model, and (3) the second stage predictor as well as the total ARD module. These results demonstrate that the baselined ARD module meets all design objectives for mission control center orbital flight test launch/abort support.
Flight Test of an Intelligent Flight-Control System
Davidson, Ron; Bosworth, John T.; Jacobson, Steven R.; Thomson, Michael Pl; Jorgensen, Charles C.
2003-01-01
The F-15 Advanced Controls Technology for Integrated Vehicles (ACTIVE) airplane (see figure) was the test bed for a flight test of an intelligent flight control system (IFCS). This IFCS utilizes a neural network to determine critical stability and control derivatives for a control law, the real-time gains of which are computed by an algorithm that solves the Riccati equation. These derivatives are also used to identify the parameters of a dynamic model of the airplane. The model is used in a model-following portion of the control law, in order to provide specific vehicle handling characteristics. The flight test of the IFCS marks the initiation of the Intelligent Flight Control System Advanced Concept Program (IFCS ACP), which is a collaboration between NASA and Boeing Phantom Works. The goals of the IFCS ACP are to (1) develop the concept of a flight-control system that uses neural-network technology to identify aircraft characteristics to provide optimal aircraft performance, (2) develop a self-training neural network to update estimates of aircraft properties in flight, and (3) demonstrate the aforementioned concepts on the F-15 ACTIVE airplane in flight. The activities of the initial IFCS ACP were divided into three Phases, each devoted to the attainment of a different objective. The objective of Phase I was to develop a pre-trained neural network to store and recall the wind-tunnel-based stability and control derivatives of the vehicle. The objective of Phase II was to develop a neural network that can learn how to adjust the stability and control derivatives to account for failures or modeling deficiencies. The objective of Phase III was to develop a flight control system that uses the neural network outputs as a basis for controlling the aircraft. The flight test of the IFCS was performed in stages. In the first stage, the Phase I version of the pre-trained neural network was flown in a passive mode. The neural network software was running using flight data

Flight research and testing form a critical link in the aeronautic research and development chain. Brilliant concepts, elegant theories, and even sophisticated ground tests of flight vehicles are not sufficient to prove beyond a doubt that an unproven aeronautical concept will actually perform as predicted. Flight research and testing provide the ultimate proof that an idea or concept performs as expected. Ever since the Wright brothers, flight research and testing were the crucible in which aeronautical concepts were advanced and proven to the point that engineers and companies are willing to stake their future to produce and design aircraft. This is still true today, as shown by the development of the experimental X-30 aerospace plane. The Dryden Flight Research Center (Ames-Dryden) continues to be involved in a number of flight research programs that require understanding and characterization of the total airplane in all the aeronautical disciplines, for example the X-29. Other programs such as the F-14 variable-sweep transition flight experiment have focused on a single concept or discipline. Ames-Dryden also continues to conduct flight and ground based experiments to improve and expand the ability to test and evaluate advanced aeronautical concepts. A review of significant aeronautical flight research programs and experiments is presented to illustrate both the progress being made and the challenges to come.
A Simple Test of Abortion and Crime

2009-01-01
I first replicate Donohue and Levitt's results for violent and property crime arrest rates. I apply their data and specification to an analysis of age-specific homicide rates and murder arrest rates. The coefficients on the abortion rate have the wrong sign for two of the four measures of crime and none is statistically significant at conventional levels. I then use the legalization of abortion in 1973 to exploit two sources of variation: between-state changes in abortion rates before and aft...
Therapeutic abortion follow-up study.

To determine the long-range psychological effects of therapeutic abortion, 50 women (aged from 13-44 years), who were granted abortions between 1967 and 1968 Because of possible impairment of mental and/or physical health, were analyzed by use of demographic questionnaires, psychological tests, and interviews. Testing revealed that 44 women had psychiatric problems at time of abortion. 43 patients were followed for 3-6 months. The follow-up interviews revealed that 29 patients reacted positively after abortion, 10 reported no significant change and 4 reacted negatively. 37 would definitely repeat the abortion. Women under 21 years of age felt substantially more ambivalent and guilty than older patients. A study of 36 paired pre- and post-abortion profiles showed that 15 initially abnormal tests had become normal. There was a significant increase in contraceptive use among the patients after the abortion, but 4 again became pregnant and 8 were apparently without consistent contraception. It is concluded that the abortions were therapeutic, but physicians are encouraged to be aware of psychological problems in abortion cases. Strong psychological and contraceptive counselling should be exercised.
Continuous Improvements to East Coast Abort Landings for Space Shuttle Aborts
Butler, Kevin D.
2003-01-01
Improvement initiatives in the areas of guidance, flight control, and mission operations provide increased capability for successful East Coast Abort Landings (ECAL). Automating manual crew procedures in the Space Shuttle's onboard guidance allows faster and more precise commanding of flight control parameters needed for successful ECALs. Automation also provides additional capability in areas not possible with manual control. Operational changes in the mission concept allow for the addition of new landing sites and different ascent trajectories that increase the regions of a successful landing. The larger regions of ECAL capability increase the safety of the crew and Orbiter.

In recent RHIC operational runs, planned and unplanned pre-fire triggered beam aborts have been observed that resulted in quenches of SC main ring magnets, indicating a weakened magnet kick strength due to beam-induced ferrite heating. An improvement program was initiated to reduce the longitudinal coupling impedance with changes to the ferrite material and the eddy-current strip geometry. Results of the impedance measurements and of magnet heating tests with CMD10 ferrite up to 190°C are reported. All 10 abort kickers in the tunnel have been modified and were provided with a cooling system for the RUN 15.
Religion and attitudes toward abortion and abortion policy in Brazil.
Ogland, Curtis P; Verona, Ana Paula
2011-01-01
This study examines the association between religion and attitudes toward the practice of abortion and abortion policy in Brazil. Drawing upon data from the 2002 Brazilian Social Research Survey (BSRS), we test a number of hypotheses with regard to the role of religion on opposition to the practice of abortion and its legalization. Findings indicate that frequently attending Pentecostals demonstrate the strongest opposition to the practice of abortion and both frequently attending Pentecostals and Catholics demonstrate the strongest opposition to its legalization. Additional religious factors, such as a commitment to biblical literalism, were also found to be significantly associated with opposition to both abortion issues. Ultimately, the findings have implications for the future of public policy on abortion and other contentious social issues in Brazil.

Supersonic Retropropulsion Flight Test Concepts

2011-01-01
NASA's Exploration Technology Development and Demonstration Program has proposed plans for a series of three sub-scale flight tests at Earth for supersonic retropropulsion, a candidate decelerator technology for future, high-mass Mars missions. The first flight test in this series is intended to be a proof-of-concept test, demonstrating successful initiation and operation of supersonic retropropulsion at conditions that replicate the relevant physics of the aerodynamic-propulsive interactions expected in flight. Five sub-scale flight test article concepts, each designed for launch on sounding rockets, have been developed in consideration of this proof-of-concept flight test. Commercial, off-the-shelf components are utilized as much as possible in each concept. The design merits of the concepts are compared along with their predicted performance for a baseline trajectory. The results of a packaging study and performance-based trade studies indicate that a sounding rocket is a viable launch platform for this proof-of-concept test of supersonic retropropulsion.

The safety of astronauts would be severely threatened if the lunar-landing spacecraft were under an emergency during the near moon phase of flight, which was far from the Earth. For the problem of mission abort caused by the main engine (service propulsion system, SPS) failure during lunar orbit insertion, firstly, the family of trajectories resulted from SPS premature shutdown and corresponding abort trajectories were analyzed; then an algorithm that can be applied to the near moon abort trajectories was proposed using patched-conic technique. The characteristics of the abort trajectory, such as energy consumption and return time of flight, were analyzed and presented. Finally, simulation examples were given to demonstrate various cases of near moon SPS failure. The results of the simulation have validated the approach proposed.

The NASA Dryden Flight Research Center has completed the initial flight test of a modified set of F/A-18 flight control computers that gives the aircraft a research control law capability. The production support flight control computers (PSFCC) provide an increased capability for flight research in the control law, handling qualities, and flight systems areas. The PSFCC feature a research flight control processor that is "piggybacked" onto the baseline F/A-18 flight control system. This research processor allows for pilot selection of research control law operation in flight. To validate flight operation, a replication of a standard F/A-18 control law was programmed into the research processor and flight-tested over a limited envelope. This paper provides a brief description of the system, summarizes the initial flight test of the PSFCC, and describes future experiments for the PSFCC.
Current problems regarding abortion, prenatal genetic testing and managing pregnancy

Full Text Available Current ethical and legal issues with regard to abortion, prenatal genetic testing and managing pregnancy are discussed in this paper. These problems are considered from the legal theory point of view as well as from the standpoint of the Serbian Law, the European Convention for the Protection of Human Rights and Fundamental Freedoms, European Court of Human Rights, legal regulations of several EU countries, the USA, Japan, and their judicial practice. First, the pregnancy termination standards that exist in Serbia are introduced. Then the following issues are explained separately: the pro life and pro choice approaches to abortion; abortion according to the legal approach as a way of survival; the moral and legal status of the fetus; prenatal genetic testing, and finally matters regarding managing pregnancy today. Moral and legal principals of autonomy, namely freedom of choice of the individual, privacy and self-determination give women the right to terminate unwanted pregnancies. In addition, the basic question is whether the right of the woman to abortion clashes with the rights of others. Firstly, with the right of the "fetus to life". Secondly, with the right of the state to intervene in the interest of protecting "the life of the fetus". Third, with the rights of the woman’s partner. The fetus has the moral right to life, but less in relation to the same right of the woman as well as in relation to her right to control her life and her physical and moral integrity. On the other hand, the value of the life of the fetus increases morally and legally with the maturity of gestation; from the third trimester, the interest of the state prevails in the protection of the "life of the fetus" except when the life or health of the pregnant woman are at risk. As regards the rights of the woman’s partner, namely the husband’s opinion, there is no legal significance. The law does not request his participation in the decision on abortion because

2005-01-01
The NASA F-15 Intelligent Flight Control System project team has developed a series of flight control concepts designed to demonstrate the benefits of a neural network-based adaptive controller. The objective of the team was to develop and flight-test control systems that use neural network technology, to optimize the performance of the aircraft under nominal conditions, and to stabilize the aircraft under failure conditions. Failure conditions include locked or failed control surfaces as well as unforeseen damage that might occur to the aircraft in flight. The Intelligent Flight Control System team is currently in the process of implementing a second generation control scheme, collectively known as Generation 2 or Gen 2, for flight testing on the NASA F-15 aircraft. This report describes the Gen 2 system as implemented by the team for flight test evaluation. Simulation results are shown which describe the experiment to be performed in flight and highlight the ways in which the Gen 2 system meets the defined objectives.

Five flight tests of the Digital Automated Landing System (DIALS) were conducted on the Advanced Transport Operating Systems (ATOPS) Transportation Research Vehicle (TSRV) -- a modified Boeing 737 aircraft for advanced controls and displays research. These flight tests were conducted at NASA's Wallops Flight Center using the microwave landing system (MLS) installation on runway 22. This report describes the flight software equations of the DIALS which was designed using modern control theory direct-digital design methods and employed a constant gain Kalman filter. Selected flight test performance data is presented for localizer (runway centerline) capture and track at various intercept angles, for glideslope capture and track of 3, 4.5, and 5 degree glideslopes, for the decrab maneuver, and for the flare maneuver. Data is also presented to illustrate the system performance in the presence of cross, gust, and shear winds. The mean and standard deviation of the peak position errors for localizer capture were, respectively, 24 feet and 26 feet. For mild wind conditions, glideslope and localizer tracking position errors did not exceed, respectively, 5 and 20 feet. For gusty wind conditions (8 to 10 knots), these errors were, respectively, 10 and 30 feet. Ten hands off automatic lands were performed. The standard deviation of the touchdown position and velocity errors from the mean values were, respectively, 244 feet and 0.7 feet/sec.
Ares I-X Flight Test Philosophy
Davis, S. R.; Tuma, M. L.; Heitzman, K.
2007-01-01
In response to the Vision for Space Exploration, the National Aeronautics and Space Administration (NASA) has defined a new space exploration architecture to return humans to the Moon and prepare for human exploration of Mars. One of the first new developments will be the Ares I Crew Launch Vehicle (CLV), which will carry the Orion Crew Exploration Vehicle (CEV), into Low Earth Orbit (LEO) to support International Space Station (ISS) missions and, later, support lunar missions. As part of Ares I development, NASA will perform a series of Ares I flight tests. The tests will provide data that will inform the engineering and design process and verify the flight hardware and software. The data gained from the flight tests will be used to certify the new Ares/Orion vehicle for human space flight. The primary objectives of this first flight test (Ares I-X) are the following: Demonstrate control of a dynamically similar integrated Ares CLV/Orion CEV using Ares CLV ascent control algorithms; Perform an in-flight separation/staging event between an Ares I-similar First Stage and a representative Upper Stage; Demonstrate assembly and recovery of a new Ares CLV-like First Stage element at Kennedy Space Center (KSC); Demonstrate First Stage separation sequencing, and quantify First Stage atmospheric entry dynamics and parachute performance; and Characterize the magnitude of the integrated vehicle roll torque throughout the First Stage (powered) flight. This paper will provide an overview of the Ares I-X flight test process and details of the individual flight tests.

Two tests supporting development of the launch abort system for the Orion MultiPurpose Crew Vehicle were run in the NASA Ames Unitary Plan wind tunnel last year. The first test used a fully metric model to examine the stability and controllability of the Launch Abort Vehicle during potential abort scenarios for Mach numbers ranging from 0.3 to 2.5. The aerodynamic effects of the Abort Motor and Attitude Control Motor plumes were simulated using high-pressure air flowing through independent paths. The aerodynamic effects of the proximity to the launch vehicle during the early moments of an abort were simulated with a remotely actuated Service Module that allowed the position relative to the Crew Module to be varied appropriately. The second test simulated the acoustic environment around the Launch Abort Vehicle caused by the plumes from the 400,000-pound thrust, solid-fueled Abort Motor. To obtain the proper acoustic characteristics of the hot rocket plumes for the flight vehicle, heated Helium was used. A custom Helium supply system was developed for the test consisting of 2 jumbo high-pressure Helium trailers, a twelve-tube accumulator, and a 13MW gas-fired heater borrowed from the Propulsion Simulation Laboratory at NASA Glenn Research Center. The test provided fluctuating surface pressure measurements at over 200 points on the vehicle surface that have now been used to define the ground-testing requirements for the Orion Launch Abort Vehicle.

Frequency of abortions recorded through Dairy Herd Improvement (DHI) testing was summarized for cows with lactations completed from 2001 through 2009. For 8.5 million DHI lactations of cows that had recorded breeding dates and were >151 d pregnant at lactation termination, the frequency of recorded abortions was 1.31%. Effects of year, herd-year, month, and pregnancy stage at lactation termination; parity; breed; milk yield; herd size; geographic region; and state within region associated with DHI-recorded abortion were examined. Abortions recorded through DHI (minimum gestation of 152 d required) were more frequent during early gestation; least squares means (LSM) were 4.38, 3.27, 1.19, and 0.59% for 152 to 175, 176 to 200, 201 to 225, and 226 to 250 d pregnant, respectively. Frequency of DHI-recorded abortions was 1.40% for parity 1 and 1.01% for parity ≥ 8. Abortion frequency was highest from May through August (1.42 to 1.53%) and lowest from October through February (1.09 to 1.21%). Frequency of DHI-recorded abortions was higher for Holsteins (1.32%) than for Jerseys (1.10%) and other breeds (1.27%). Little relationship was found between DHI-recorded abortions and herd size. Abortion frequencies for effects should be considered to be underestimated because many abortions, especially those caused by genetic recessives, go undetected. Therefore, various nonreturn rates (NRR; 60, 80, …, 200 d) were calculated to document pregnancy loss confirmed by the absence of homozygotes in the population. Breeding records for April 2011 US Department of Agriculture sire conception rate evaluations were analyzed with the model used for official evaluations with the addition of an interaction between carrier status of the service sire (embryo's sire) and cow sire (embryo's maternal grandsire). Over 13 million matings were examined using various NRR for Holstein lethal recessive traits (brachyspina and complex vertebral malformation) and undesirable recessive haplotypes (HH1
Free Flight Ground Testing of ADEPT in Advance of the Sounding Rocket One Flight Experiment
Smith, B. P.; Dutta, S.
2017-01-01
The Adaptable Deployable Entry and Placement Technology (ADEPT) project will be conducting the first flight test of ADEPT, titled Sounding Rocket One (SR-1), in just two months. The need for this flight test stems from the fact that ADEPT's supersonic dynamic stability has not yet been characterized. The SR-1 flight test will provide critical data describing the flight mechanics of ADEPT in ballistic flight. These data will feed decision making on future ADEPT mission designs. This presentation will describe the SR-1 scientific data products, possible flight test outcomes, and the implications of those outcomes on future ADEPT development. In addition, this presentation will describe free-flight ground testing performed in advance of the flight test. A subsonic flight dynamics test conducted at the Vertical Spin Tunnel located at NASA Langley Research Center provided subsonic flight dynamics data at high and low altitudes for multiple center of mass (CoM) locations. A ballistic range test at the Hypervelocity Free Flight Aerodynamics Facility (HFFAF) located at NASA Ames Research Center provided supersonic flight dynamics data at low supersonic Mach numbers. Execution and outcomes of these tests will be discussed. Finally, a hypothesized trajectory estimate for the SR-1 flight will be presented.

This paper addresses the problem of building trust in the online prediction of a battery powered aircraft's remaining flying time. A series of flight tests is described that make use of a small electric powered unmanned aerial vehicle (eUAV) to verify the performance of the remaining flying time prediction algorithm. The estimate of remaining flying time is used to activate an alarm when the predicted remaining time is two minutes. This notifies the pilot to transition to the landing phase of the flight. A second alarm is activated when the battery charge falls below a specified limit threshold. This threshold is the point at which the battery energy reserve would no longer safely support two repeated aborted landing attempts. During the test series, the motor system is operated with the same predefined timed airspeed profile for each test. To test the robustness of the prediction, half of the tests were performed with, and half were performed without, a simulated powertrain fault. The pilot remotely engages a resistor bank at a specified time during the test flight to simulate a partial powertrain fault. The flying time prediction system is agnostic of the pilot's activation of the fault and must adapt to the vehicle's state. The time at which the limit threshold on battery charge is reached is then used to measure the accuracy of the remaining flying time predictions. Accuracy requirements for the alarms are considered and the results discussed.

Post-abortion and induced abortion services in two public hospitals in Colombia.
Darney, Blair G; Simancas-Mendoza, Willis; Edelman, Alison B; Guerra-Palacio, Camilo; Tolosa, Jorge E; Rodriguez, Maria I
2014-07-01
Until 2006, legal induced abortion was completely banned in Colombia. Few facilities are equipped or willing to offer abortion services; often adolescents experience even greater barriers of access in this context. We examined post abortion care (PAC) and legal induced abortion in two large public hospitals. We tested the association of hospital site, procedure type (manual vacuum aspiration vs. sharp curettage), and age (adolescents vs. women 20 years and over) with service type (PAC or legal induced abortion). Retrospective cohort study using 2010 billing data routinely collected for reimbursement (N=1353 procedures). We utilized descriptive statistics, multivariable logistic regression and predicted probabilities. Adolescents made up 22% of the overall sample (300/1353). Manual vacuum aspiration was used in one-third of cases (vs. sharp curettage). Adolescents had lower odds of documented PAC (vs. induced abortion) compared with women over age 20 (OR=0.42; 95% CI=0.21-0.86). The absolute difference of service type by age, however, is very small, controlling for hospital site and procedure type (.97 probability of PAC for adolescents compared with .99 for women 20 and over). Regardless of age, PAC via sharp curettage is the current standard in these two public hospitals. Both adolescents and women over 20 are in need of access to legal abortion services utilizing modern technologies in the public sector in Colombia. Documentation of abortion care is an essential first step to determining barriers to access and opportunities for quality improvement and better health outcomes for women. Following partial decriminalization of abortion in Colombia, in public hospitals nearly all abortion services are post-abortion care, not induced abortion. Sharp curettage is the dominant treatment for both adolescents and women over 20. Women seek care in the public sector for abortion, and must have access to safe, quality services. Copyright © 2014.

The integrated Flight Test 4 (FT4) will gather data for the UAS researchers Sense and Avoid systems (referred to as Detect and Avoid in the RTCA SC 228 ToR) algorithms and pilot displays for candidate UAS systems in a relevant environment. The technical goals of FT4 are to: 1) perform end-to-end traffic encounter test of pilot guidance generated by DAA algorithms; 2) collect data to inform the initial Minimum Operational Performance Standards (MOPS) for Detect and Avoid systems. FT4 objectives and test infrastructure builds from previous UAS project simulations and flight tests. NASA Ames (ARC), NASA Armstrong (AFRC), and NASA Langley (LaRC) Research Centers will share responsibility for conducting the tests, each providing a test lab and critical functionality. UAS-NAS project support and participation on the 2014 flight test of ACAS Xu and DAA Self Separation (SS) significantly contributed to building up infrastructure and procedures for FT3 as well. The DAA Scripted flight test (FT4) will be conducted out of NASA Armstrong over an eight-week period beginning in April 2016.
Selected Flight Test Results for Online Learning Neural Network-Based Flight Control System
Williams-Hayes, Peggy S.
2004-01-01
The NASA F-15 Intelligent Flight Control System project team developed a series of flight control concepts designed to demonstrate neural network-based adaptive controller benefits, with the objective to develop and flight-test control systems using neural network technology to optimize aircraft performance under nominal conditions and stabilize the aircraft under failure conditions. This report presents flight-test results for an adaptive controller using stability and control derivative values from an online learning neural network. A dynamic cell structure neural network is used in conjunction with a real-time parameter identification algorithm to estimate aerodynamic stability and control derivative increments to baseline aerodynamic derivatives in flight. This open-loop flight test set was performed in preparation for a future phase in which the learning neural network and parameter identification algorithm output would provide the flight controller with aerodynamic stability and control derivative updates in near real time. Two flight maneuvers are analyzed - pitch frequency sweep and automated flight-test maneuver designed to optimally excite the parameter identification algorithm in all axes. Frequency responses generated from flight data are compared to those obtained from nonlinear simulation runs. Flight data examination shows that addition of flight-identified aerodynamic derivative increments into the simulation improved aircraft pitch handling qualities.

Abortion patients' perceptions of abortion regulation.
Cockrill, Kate; Weitz, Tracy A
2010-01-01
Most states regulate abortion differently than other health care services. Examples of these regulations include mandating waiting periods and the provision of state-authored information, and prohibiting private and public insurance coverage for abortion. The primary purpose of this paper is to explore abortion patients' perspectives on these regulations. We recruited 20 participants from three abortion providing facilities located in two states in the U.S. South and Midwest. Using a survey and semistructured interview, we collected information about women's knowledge of abortion regulation and policy preferences. During the interviews, women weighed the pros and cons of abortion regulations. We used grounded theory analytical techniques and matrix analysis to organize and interpret the data. We discovered five themes in these women's considerations of regulation: responsibility, empathy, safe and accessible health care, privacy, and equity. Women in the study generally supported policies that they felt protected women or informed decisions. However, most women also opposed laws mandating two-day abortion appointments for women who were traveling long distances. Women tended to favor financial coverage of abortion, arguing that it could help poor women afford abortion or reduce state expenditures. Overall the study participants' opinions on abortion policy reflect key values for advocates and policy makers to consider: responsibility, empathy, safe and accessible health care, privacy, and equity. Future work should examine abortion regulations in light of these shared values. Laws that promote misinformation or prohibit accommodations of unique circumstances are not consistent the positions articulated by the subjects in our study. Copyright 2010 Jacobs Institute of Women
Remotely Piloted Vehicles for Experimental Flight Control Testing
Motter, Mark A.; High, James W.
2009-01-01
A successful flight test and training campaign of the NASA Flying Controls Testbed was conducted at Naval Outlying Field, Webster Field, MD during 2008. Both the prop and jet-powered versions of the subscale, remotely piloted testbeds were used to test representative experimental flight controllers. These testbeds were developed by the Subsonic Fixed Wing Project s emphasis on new flight test techniques. The Subsonic Fixed Wing Project is under the Fundamental Aeronautics Program of NASA's Aeronautics Research Mission Directorate (ARMD). The purpose of these testbeds is to quickly and inexpensively evaluate advanced concepts and experimental flight controls, with applications to adaptive control, system identification, novel control effectors, correlation of subscale flight tests with wind tunnel results, and autonomous operations. Flight tests and operator training were conducted during four separate series of tests during April, May, June and August 2008. Experimental controllers were engaged and disengaged during fully autonomous flight in the designated test area. Flaps and landing gear were deployed by commands from the ground control station as unanticipated disturbances. The flight tests were performed NASA personnel with support from the Maritime Unmanned Development and Operations (MUDO) team of the Naval Air Warfare Center, Aircraft Division
A Dynamic Risk Model for Evaluation of Space Shuttle Abort Scenarios
Henderson, Edward M.; Maggio, Gaspare; Elrada, Hassan A.; Yazdpour, Sabrina J.
2003-01-01
The Space Shuttle is an advanced manned launch system with a respectable history of service and a demonstrated level of safety. Recent studies have shown that the Space Shuttle has a relatively low probability of having a failure that is instantaneously catastrophic during nominal flight as compared with many US and international launch systems. However, since the Space Shuttle is a manned. system, a number of mission abort contingencies exist to primarily ensure the safety of the crew during off-nominal situations and to attempt to maintain the integrity of the Orbiter. As the Space Shuttle ascends to orbit it transverses various intact abort regions evaluated and planned before the flight to ensure that the Space Shuttle Orbiter, along with its crew, may be returned intact either to the original launch site, a transoceanic landing site, or returned from a substandard orbit. An intact abort may be initiated due to a number of system failures but the highest likelihood and most challenging abort scenarios are initiated by a premature shutdown of a Space Shuttle Main Engine (SSME). The potential consequences of such a shutdown vary as a function of a number of mission parameters but all of them may be related to mission time for a specific mission profile. This paper focuses on the Dynamic Abort Risk Evaluation (DARE) model process, applications, and its capability to evaluate the risk of Loss Of Vehicle (LOV) due to the complex systems interactions that occur during Space Shuttle intact abort scenarios. In addition, the paper will examine which of the Space Shuttle subsystems are critical to ensuring a successful return of the Space Shuttle Orbiter and crew from such a situation.
Writing executable assertions to test flight software
Mahmood, A.; Andrews, D. M.; Mccluskey, E. J.
1984-01-01
An executable assertion is a logical statement about the variables or a block of code. If there is no error during execution, the assertion statement results in a true value. Executable assertions can be used for dynamic testing of software. They can be employed for validation during the design phase, and exception and error detection during the operation phase. The present investigation is concerned with the problem of writing executable assertions, taking into account the use of assertions for testing flight software. They can be employed for validation during the design phase, and for exception handling and error detection during the operation phase The digital flight control system and the flight control software are discussed. The considered system provides autopilot and flight director modes of operation for automatic and manual control of the aircraft during all phases of flight. Attention is given to techniques for writing and using assertions to test flight software, an experimental setup to test flight software, and language features to support efficient use of assertions.
Flight Testing an Iced Business Jet for Flight Simulation Model Validation
Ratvasky, Thomas P.; Barnhart, Billy P.; Lee, Sam; Cooper, Jon
2007-01-01
A flight test of a business jet aircraft with various ice accretions was performed to obtain data to validate flight simulation models developed through wind tunnel tests. Three types of ice accretions were tested: pre-activation roughness, runback shapes that form downstream of the thermal wing ice protection system, and a wing ice protection system failure shape. The high fidelity flight simulation models of this business jet aircraft were validated using a software tool called "Overdrive." Through comparisons of flight-extracted aerodynamic forces and moments to simulation-predicted forces and moments, the simulation models were successfully validated. Only minor adjustments in the simulation database were required to obtain adequate match, signifying the process used to develop the simulation models was successful. The simulation models were implemented in the NASA Ice Contamination Effects Flight Training Device (ICEFTD) to enable company pilots to evaluate flight characteristics of the simulation models. By and large, the pilots confirmed good similarities in the flight characteristics when compared to the real airplane. However, pilots noted pitch up tendencies at stall with the flaps extended that were not representative of the airplane and identified some differences in pilot forces. The elevator hinge moment model and implementation of the control forces on the ICEFTD were identified as a driver in the pitch ups and control force issues, and will be an area for future work.

The Alan Guttmacher Institute's State Reproductive Health Monitor "Legislative Proposals and Actions" provides US legislative information on abortion. The listing contains information on pending bills: the state, the identifying legislative number, the sponsor, the committee, the date the bill was introduced, a description of the bill, and when available the bill's status. The bills cover: 1) clinic licensing, e.g., requiring outpatient health care facilities in which abortions are performed, to have malpractice liability insurance; 2) comprehensive statues, which require parental notification before minor may obtain abortions, mandate abortion counseling to all women 24 hours before the abortion can be performed and prohibit disciplining or discharging a state employee for refusing to provide abortion counseling; 3) fetal personhood and rights, e.g. providing that life is vested in each person at fertilization; 4) fetal research and remains; 5) gender of fetus, which regulate abortions relative to sex selection in pregnancies; 6) harassment regulation; 7) informed consent and waiting periods detailing the risks and alternatives to abortion, and the 24-hour waiting period; 8) insurance coverage, e.g., eliminating language banning the coverage of abortions for state workers, and prohibiting disclosure by a health insurance carrier to the employer of a claimant that the claimant had a surgical abortion; 9) legality of abortion, urging Congress to reject he Freedom of Choice Act; 10) parental consent and notification; 11) postviability requirements; 12) public funding; 13) reporting requirements; 14) reproductive rights, and 15) spousal and paternal consent and notification.
Abort Options for Human Missions to Earth-Moon Halo Orbits
Jesick, Mark C.
2013-01-01
Abort trajectories are optimized for human halo orbit missions about the translunar libration point (L2), with an emphasis on the use of free return trajectories. Optimal transfers from outbound free returns to L2 halo orbits are numerically optimized in the four-body ephemeris model. Circumlunar free returns are used for direct transfers, and cislunar free returns are used in combination with lunar gravity assists to reduce propulsive requirements. Trends in orbit insertion cost and flight time are documented across the southern L2 halo family as a function of halo orbit position and free return flight time. It is determined that the maximum amplitude southern halo incurs the lowest orbit insertion cost for direct transfers but the maximum cost for lunar gravity assist transfers. The minimum amplitude halo is the most expensive destination for direct transfers but the least expensive for lunar gravity assist transfers. The on-orbit abort costs for three halos are computed as a function of abort time and return time. Finally, an architecture analysis is performed to determine launch and on-orbit vehicle requirements for halo orbit missions.
[Abortion and rights. Legal thinking about abortion].
Perez Duarte, A E
1991-01-01
Analysis of abortion in Mexico from a juridical perspective requires recognition that Mexico as a national community participates in a double system of values. Politically it is defined as a liberal, democratic, and secular state, but culturally the Judeo-Christian ideology is dominant in all social strata. This duality complicates all juridical-penal decisions regarding abortion. Public opinion on abortion is influenced on the 1 hand by extremely conservative groups who condemn abortion as homicide, and on the other hand by groups who demand legislative reform in congruence with characteristics that define the state: an attitude of tolerance toward the different ideological-moral positions that coexist in the country. The discussion concerns the rights of women to voluntary maternity, protection of health, and to making their own decisions regarding their bodies vs. the rights of the fetus to life. The type of analysis is not objective, and conclusions depend on the ideology of the analyst. Other elements must be examined for an objective consideration of the social problem of abortion. For example, aspects related to maternal morbidity and mortality and the demographic, economic, and physical and mental health of the population would all seem to support the democratic juridical doctrine that sees the clandestine nature of abortion as the principal problem. It is also observed that the illegality of abortion does not guarantee its elimination. Desperate women will seek abortion under any circumstances. The illegality of abortion also impedes health and educational policies that would lower abortion mortality. There are various problems from a strictly juridical perspective. A correct definition of the term abortion is needed that would coincide with the medical definition. The discussion must be clearly centered on the protected juridical right and the definition of reproductive and health rights and rights to their own bodies of women. The experiences of other

Flight Test Maneuvers for Efficient Aerodynamic Modeling
Morelli, Eugene A.
2011-01-01
Novel flight test maneuvers for efficient aerodynamic modeling were developed and demonstrated in flight. Orthogonal optimized multi-sine inputs were applied to aircraft control surfaces to excite aircraft dynamic response in all six degrees of freedom simultaneously while keeping the aircraft close to chosen reference flight conditions. Each maneuver was designed for a specific modeling task that cannot be adequately or efficiently accomplished using conventional flight test maneuvers. All of the new maneuvers were first described and explained, then demonstrated on a subscale jet transport aircraft in flight. Real-time and post-flight modeling results obtained using equation-error parameter estimation in the frequency domain were used to show the effectiveness and efficiency of the new maneuvers, as well as the quality of the aerodynamic models that can be identified from the resultant flight data.
Fused Reality for Enhanced Flight Test Capabilities
Bachelder, Ed; Klyde, David
2011-01-01
The feasibility of using Fused Reality-based simulation technology to enhance flight test capabilities has been investigated. In terms of relevancy to piloted evaluation, there remains no substitute for actual flight tests, even when considering the fidelity and effectiveness of modern ground-based simulators. In addition to real-world cueing (vestibular, visual, aural, environmental, etc.), flight tests provide subtle but key intangibles that cannot be duplicated in a ground-based simulator. There is, however, a cost to be paid for the benefits of flight in terms of budget, mission complexity, and safety, including the need for ground and control-room personnel, additional aircraft, etc. A Fused Reality(tm) (FR) Flight system was developed that allows a virtual environment to be integrated with the test aircraft so that tasks such as aerial refueling, formation flying, or approach and landing can be accomplished without additional aircraft resources or the risk of operating in close proximity to the ground or other aircraft. Furthermore, the dynamic motions of the simulated objects can be directly correlated with the responses of the test aircraft. The FR Flight system will allow real-time observation of, and manual interaction with, the cockpit environment that serves as a frame for the virtual out-the-window scene.
Free Flight Rotorcraft Flight Test Vehicle Technology Development
Hodges, W. Todd; Walker, Gregory W.
1994-01-01
A rotary wing, unmanned air vehicle (UAV) is being developed as a research tool at the NASA Langley Research Center by the U.S. Army and NASA. This development program is intended to provide the rotorcraft research community an intermediate step between rotorcraft wind tunnel testing and full scale manned flight testing. The technologies under development for this vehicle are: adaptive electronic flight control systems incorporating artificial intelligence (AI) techniques, small-light weight sophisticated sensors, advanced telepresence-telerobotics systems and rotary wing UAV operational procedures. This paper briefly describes the system's requirements and the techniques used to integrate the various technologies to meet these requirements. The paper also discusses the status of the development effort. In addition to the original aeromechanics research mission, the technology development effort has generated a great deal of interest in the UAV community for related spin-off applications, as briefly described at the end of the paper. In some cases the technologies under development in the free flight program are critical to the ability to perform some applications.
Acoustic-Modal Testing of the Ares I Launch Abort System Attitude Control Motor Valve
Davis, R. Benjamin; Fischbach, Sean R.
2010-01-01
The Attitude Control Motor (ACM) is being developed for use in the Launch Abort System (LAS) of NASA's Ares I launch vehicle. The ACM consists of a small solid rocket motor and eight actuated pintle valves that directionally allocate.thrust_- 1t.has-been- predicted-that significant unsteady. pressure.fluctuations.will.exist. inside the-valves during operation. The dominant frequencies of these oscillations correspond to the lowest several acoustic natural frequencies of the individual valves. An acoustic finite element model of the fluid volume inside the valve has been critical to the prediction of these frequencies and their associated mode shapes. This work describes an effort to experimentally validate the acoustic finite model of the valve with an acoustic modal test. The modal test involved instrumenting a flight-like valve with six microphones and then exciting the enclosed air with a loudspeaker. The loudspeaker was configured to deliver broadband noise at relatively high sound pressure levels. The aquired microphone signals were post-processed and compared to results generated from the acoustic finite element model. Initial comparisons between the test data and the model results revealed that additional model refinement was necessary. Specifically, the model was updated to implement a complex impedance boundary condition at the entrance to the valve supply tube. This boundary condition models the frequency-dependent impedance that an acoustic wave will encounter as it reaches the end of the supply tube. Upon invoking this boundary condition, significantly improved agreement between the test data and the model was realized.

The navigation and flight director guidance systems implemented in the NASA/FAA helicopter microwave landing system (MLS) curved approach flight test program is described. Flight test were conducted at the U.S. Navy's Crows Landing facility, using the NASA Ames UH-lH helicopter equipped with the V/STOLAND avionics system. The purpose of these tests was to investigate the feasibility of flying complex, curved and descending approaches to a landing using MLS flight director guidance. A description of the navigation aids used, the avionics system, cockpit instrumentation and on-board navigation equipment used for the flight test is provided. Three generic reference flight paths were developed and flown during the test. They were as follows: U-Turn, S-turn and Straight-In flight profiles. These profiles and their geometries are described in detail. A 3-cue flight director was implemented on the helicopter. A description of the formulation and implementation of the flight director laws is also presented. Performance data and analysis is presented for one pilot conducting the flight director approaches.
Demand for abortion and post abortion care in Ibadan, Nigeria.
Awoyemi, Bosede O; Novignon, Jacob
2014-01-01
While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers' education was only statistically significant in determining abortion demand but not post-abortion care demand. The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this in the absence of proper post-abortion
Demand for abortion and post abortion care in Ibadan, Nigeria
2014-01-01
Background While induced abortion is considered to be illegal and socially unacceptable in Nigeria, it is still practiced by many women in the country. Poor family planning and unsafe abortion practices have daunting effects on maternal health. For instance, Nigeria is on the verge of not meeting the Millennium development goals on maternal health due to high maternal mortality ratio, estimated to be about 630 maternal deaths per 100,000 live births. Recent evidences have shown that a major factor in this trend is the high incidence of abortion in the country. The objective of this paper is, therefore, to investigate the factors determining the demand for abortion and post-abortion care in Ibadan city of Nigeria. Methods The study employed data from a hospital-based/exploratory survey carried out between March to September 2010. Closed ended questionnaires were administered to a sample of 384 women of reproductive age from three hospitals within the Ibadan metropolis in South West Nigeria. However, only 308 valid responses were received and analysed. A probit model was fitted to determine the socioeconomic factors that influence demand for abortion and post-abortion care. Results The results showed that 62% of respondents demanded for abortion while 52.3% of those that demanded for abortion received post-abortion care. The findings again showed that income was a significant determinant of abortion and post-abortion care demand. Women with higher income were more likely to demand abortion and post-abortion care. Married women were found to be less likely to demand for abortion and post-abortion care. Older women were significantly less likely to demand for abortion and post-abortion care. Mothers’ education was only statistically significant in determining abortion demand but not post-abortion care demand. Conclusion The findings suggest that while abortion is illegal in Nigeria, some women in the Ibadan city do abort unwanted pregnancies. The consequence of this

During the 2011 LHC operation, the abort gap cleaning has successfully being used at 450 GeV. The design goal of this system is to leave it active all along the LHC operational cycles, from the injection to the end of the stable beams operation. Therefore, during fall 2011, abort gap cleaning tests continued at 3.5 TeV. In this note, the results of the successful beam cleaning performed on October 7, 2011 are summarised.
Low Density Supersonic Decelerator Flight Dynamics Test-1 Flight Design and Targeting
Ivanov, Mark
2015-01-01
NASA's Low Density Supersonic Decelerator (LDSD) program was established to identify, develop, and eventually qualify to Test [i.e. Technology] Readiness Level (TRL) - 6 aerodynamic decelerators for eventual use on Mars. Through comprehensive Mars application studies, two distinct Supersonic Inflatable Aerodynamic Decelerator (SIAD) designs were chosen that afforded the optimum balance of benefit, cost, and development risk. In addition, a Supersonic Disk Sail (SSDS) parachute design was chosen that satisfied the same criteria. The final phase of the multi-tiered qualification process involves Earth Supersonic Flight Dynamics Tests (SFDTs) within environmental conditions similar to those that would be experienced during a Mars Entry, Descent, and Landing (EDL) mission. The first of these flight tests (i.e. SFDT-1) was completed on June 28, 2014 with two more tests scheduled for the summer of 2015 and 2016, respectively. The basic flight design for all the SFDT flights is for the SFDT test vehicle to be ferried to a float altitude of 120 kilo-feet by a 34 thousand cubic feet (Mcf) heavy lift helium balloon. Once float altitude is reached, the test vehicle is released from the balloon, spun-up for stability, and accelerated to supersonic speeds using a Star48 solid rocket motor. After burnout of the Star48 motor the vehicle decelerates to pre-flight selected test conditions for the deployment of the SIAD system. After further deceleration with the SIAD deployed, the SSDS parachute is then deployed stressing the performance of the parachute in the wake of the SIAD augmented blunt body. The test vehicle/SIAD/parachute system then descends to splashdown in the Pacific Ocean for eventual recovery. This paper will discuss the development of both the test vehicle and the trajectory sequence including design trade-offs resulting from the interaction of both engineering efforts. In addition, the SFDT-1 nominal trajectory design and associated sensitivities will be discussed

A preliminary survey of existing separation assurance and collision avoidance advancements, technologies, and efforts has been conducted in order to develop a concept of operations for flight testing autonomous separation assurance at Dryden Flight Research Center. This effort was part of the Unmanned Aerial Systems in the National Airspace System project. The survey focused primarily on separation assurance projects validated through flight testing (including lessons learned), however current forays into the field were also examined. Comparisons between current Dryden flight and range assets were conducted using House of Quality matrices in order to allow project management to make determinations regarding asset utilization for future flight tests. This was conducted in order to establish a body of knowledge of the current collision avoidance landscape, and thus focus Dryden s efforts more effectively towards the providing of assets and test ranges for future flight testing within this research field.

Abortions, especially those occurring during late pregnancy, lead to considerable economic losses. To estimate the financial losses related to pregnancy loss, at first the influencing factors on abortion need to be identified. Thus, the objective of this study was to determine and quantify the risk...... factors and their interactions for abortion in Iranian dairy herds. Based on data from 6 commercial herds, logistic regression was used to identify the risk factors for abortion. The basic time unit used in the study was a 3-week period corresponding to an estrus cycle.

NASA ARC has conducted flight tests of a new type of aerodynamic pressure sensor based on a luminescent surface coating. Flights were conducted at the NASA ARC-Dryden Flight Research Facility. The luminescent pressure sensor is based on a surface coating which, when illuminated with ultraviolet light, emits visible light with an intensity dependent on the local air pressure on the surface. This technique makes it possible to obtain pressure data over the entire surface of an aircraft, as opposed to conventional instrumentation, which can only make measurements at pre-selected points. The objective of the flight tests was to evaluate the effectiveness and practicality of a luminescent pressure sensor in the actual flight environment. A luminescent pressure sensor was installed on a fin, the Flight Test Fixture (FTF), that is attached to the underside of an F-104 aircraft. The response of one particular surface coating was evaluated at low supersonic Mach numbers (M = 1.0-1.6) in order to provide an initial estimate of the sensor's capabilities. This memo describes the test approach, the techniques used, and the pressure sensor's behavior under flight conditions. A direct comparison between data provided by the luminescent pressure sensor and that produced by conventional pressure instrumentation shows that the luminescent sensor can provide quantitative data under flight conditions. However, the test results also show that the sensor has a number of limitations which must be addressed if this technique is to prove useful in the flight environment.
Small-scale fixed wing airplane software verification flight test
Miller, Natasha R.
The increased demand for micro Unmanned Air Vehicles (UAV) driven by military requirements, commercial use, and academia is creating a need for the ability to quickly and accurately conduct low Reynolds Number aircraft design. There exist several open source software programs that are free or inexpensive that can be used for large scale aircraft design, but few software programs target the realm of low Reynolds Number flight. XFLR5 is an open source, free to download, software program that attempts to take into consideration viscous effects that occur at low Reynolds Number in airfoil design, 3D wing design, and 3D airplane design. An off the shelf, remote control airplane was used as a test bed to model in XFLR5 and then compared to flight test collected data. Flight test focused on the stability modes of the 3D plane, specifically the phugoid mode. Design and execution of the flight tests were accomplished for the RC airplane using methodology from full scale military airplane test procedures. Results from flight test were not conclusive in determining the accuracy of the XFLR5 software program. There were several sources of uncertainty that did not allow for a full analysis of the flight test results. An off the shelf drone autopilot was used as a data collection device for flight testing. The precision and accuracy of the autopilot is unknown. Potential future work should investigate flight test methods for small scale UAV flight.
Misperceptions about the risks of abortion in women presenting for abortion.

Misinformation about the risks and sequelae of abortion is widespread. The purpose of this study was to examine whether women having an abortion who believe that there should be restrictions to abortion (i.e., that some other women should not be allowed to have an abortion) also believe this misinformation about the health risks associated with abortion. We carried out a cross-sectional survey of women presenting consecutively for an abortion at an urban abortion clinic in Vancouver, British Columbia, between February and September 2012. Of 1008 women presenting for abortion, 978 completed questionnaires (97% response rate), and 333 of these (34%) favoured abortion restrictions. More women who favoured restrictions believed that the health risk of an abortion was the same as or greater than the health risk of childbirth (84.2% vs. 65.6%, P abortion caused mental health problems (39.1% vs. 28.3%, P abortion caused infertility (41.7% vs. 21.9%, P abortion should not be restricted was found to be a significantly correlated with correct answers about health risks, mental health problems, and infertility. Misinformed beliefs about the risks of abortion are common among women having an abortion. Women presenting for abortion who favoured restrictions to abortion have more misperceptions about abortion risks than women who favour no restrictions.
Shared risk aversion in spontaneous and induced abortion.

Does the incidence of spontaneous abortion correlate positively over conception cohorts with the incidence of non-clinically indicated induced abortion as predicted by shared risk aversion? We find that the number of spontaneous and non-clinically indicated induced abortions correlates in conception cohorts, suggesting that risk aversion affects both the conscious and non-conscious mechanisms that control parturition. Much literature speculates that natural selection conserved risk aversion because the trait enhanced Darwinian fitness. Risk aversion, moreover, supposedly influences all decisions including those that individuals can and cannot report making. We argue that these circumstances, if real, would manifest in conscious and non-conscious decisions to invest in prospective offspring, and therefore affect incidence of induced and spontaneous abortion over time. Using data from Denmark, we test the hypothesis that monthly conception cohorts yielding unexpectedly many non-clinically indicated induced abortions also yield unexpectedly many spontaneous abortions. The 180 month test period (January 1995 through December 2009), yielded 1 351 800 gestations including 156 780 spontaneous as well as 233 280 induced abortions 9100 of which were clinically indicated. We use Box-Jenkins transfer functions to adjust the incidence of spontaneous and non-clinically indicated induced abortions for autocorrelation (including seasonality), cohort size, and fetal as well as gestational anomalies over the 180-month test period. We use cross-correlation to test our hypothesized association. We find a positive association between spontaneous and non-clinically indicated induced abortions. This suggests, consistent with our theory, that mothers of conception cohorts that yielded more spontaneous abortions than expected opted more frequently than expected for non-clinically indicated induced abortion. Limitations of our work include that even the world's best registration system
Access to abortion: what women want from abortion services.
Wiebe, Ellen R; Sandhu, Supna
2008-04-01
Whether Canadian physicians can refuse to refer women for abortion and whether private clinics can charge for abortions are matters of controversy. We sought to identify barriers to access for women seeking therapeutic abortion and to have them identify what they considered to be most important about access to abortion services. Women presenting for abortion over a two-month period at two free-standing abortion clinics, one publicly funded and the other private, were invited to participate in the study. Phase I of the study involved administration of a questionnaire seeking information about demographics, perceived barriers to access to abortion, and what the women wanted from abortion services. Phase II involved semi-structured interviews of a convenience sample of women to record their responses to questions about access. Responses from Phase I questionnaires were compared between the two clinics, and qualitative analysis was performed on the interview responses. Of 423 eligible women, 402 completed questionnaires, and of 45 women approached, 39 completed interviews satisfactorily. Women received information about abortion services from their physicians (60.0%), the Internet (14.8%), a telephone directory (7.8%), friends or family (5.3%), or other sources (12.3%). Many had negative experiences in gaining access. The most important issue regarding access was the long wait time; the second most important issue was difficulty in making appointments. In the private clinic, 85% of the women said they were willing to pay for shorter wait times, compared with 43.5% in the public clinic. Physicians who failed to refer patients for abortion or provide information about obtaining an abortion caused distress and impeded access for a significant minority of women requesting an abortion. Management of abortion services should be prioritized to reflect what women want: particularly decreased wait times for abortion and greater ease and convenience in booking appointments

Tanzania has one of the highest maternal mortality ratios in the world, and unsafe abortion is one of its leading causes. Yet little is known about its incidence. To provide the first ever estimates of the incidence of unsafe abortion in Tanzania, at the national level and for each of the 8 geopolitical zones (7 in Mainland plus Zanzibar). A nationally representative survey of health facilities was conducted to determine the number of induced abortion complications treated in facilities. A survey of experts on abortion was conducted to estimate the likelihood of women experiencing complications and obtaining treatment. These surveys were complemented with population and fertility data to obtain abortion numbers, rates and ratios, using the Abortion Incidence Complications Methodology. In Tanzania, women obtained just over 405,000 induced abortions in 2013, for a national rate of 36 abortions per 1,000 women age 15-49 and a ratio of 21 abortions per 100 live births. For each woman treated in a facility for induced abortion complications, 6 times as many women had an abortion but did not receive care. Abortion rates vary widely by zone, from 10.7 in Zanzibar to 50.7 in the Lake zone. The abortion rate is similar to that of other countries in the region. Variations by zone are explained mainly by differences in fertility and contraceptive prevalence. Measures to reduce the incidence of unsafe abortion and associated maternal mortality include expanding access to post-abortion care and contraceptive services to prevent unintended pregnancies.

If you are pregnant and near 40 years old there is 1/137 chance that your child may have Down's syndrome, or 1/65 chance he will have a physical or mental problem. There are tests that can indicate these problems but they increase the risk of spontaneous abortion. A woman should not be forced to carry an unwanted child, and the needs of childless couples should not be addressed in abortion discussions. The Roe v. Wade case made the distinction of not having to determine when life begins, but when it can be sustained outside the body. The Missouri statute states that human life begins at conception, an unborn child has protectable life interests and the parents of that child have protectable life interests of the unborn child in relation to life, health and its well being. States that are really concerned with the interests of unborn children should improve prenatal care, educate teens on contraception, AIDS, and be concerned about violent behavior and smoking. Voters in Michigan and Arkansas approved a law to stop the use of public funds for abortion, other than saving the mother's life. Pro- choice advocates are concerned that the conservative appointees to the supreme court will reverse the previous decision.
Mental health consequences of abortion and refused abortion.
Watter, W W
1980-02-01
There is no scientific evidence to support the hypothesis put forth by Dr. Philip Ney in a recent article published in the Canadian Journal of Psychiatry that induced abortion is associated with an increase in child abuse. There are, however, numerous studies which support the contention that mandatory motherhood adversely affects the mental health of both the mother and the offspring. Studies conducted in Sweden, Scotland, and Czechoslovakia revealed that women who were refused abortions frequently experienced serious psychosocial difficulties for long periods of time following abortion refusal. Case controlled follow-up studies, conducted in Sweden and Czechoslovakia, of offspring born to women who were refused abortions demonstrated that a higher proportion of the unwanted children required psychiatric services, engaged in criminal behavior, and did less well in school than the controlled children. These studies have implications for the current Canadian law which permits a woman to obtain an abortion if pregnancy continuation will endanger her health. In view of the above statistical evidence, and the fact that mortality and morbidity are known to be lower for abortion than for childbirth, any person who denies a woman the right to have an abortion is increasing the risk that the health of the woman will be endangered. By law, therefore, all abortion requests should be honored.
A Flight Control System Architecture for the NASA AirSTAR Flight Test Infrastructure
Murch, Austin M.
2008-01-01
A flight control system architecture for the NASA AirSTAR infrastructure has been designed to address the challenges associated with safe and efficient flight testing of research control laws in adverse flight conditions. The AirSTAR flight control system provides a flexible framework that enables NASA Aviation Safety Program research objectives, and includes the ability to rapidly integrate and test research control laws, emulate component or sensor failures, inject automated control surface perturbations, and provide a baseline control law for comparison to research control laws and to increase operational efficiency. The current baseline control law uses an angle of attack command augmentation system for the pitch axis and simple stability augmentation for the roll and yaw axes.

In this article we address the issue, with a tentative empirical application to the Italian data, of the relationship, very debated mainly in north America, between abortion legalization and reduction of crime rates of youth. The rationale of this relationship is that there is a causal factor at work: the more unwanted pregnancies aborted, the less unwanted children breeding their criminal attitude in an hostile/deprived family environment. Many methodological and empirical criticisms have been raised against the proof of the existence of such a relationship: our attempt to test if this link is valid for Italy cannot endorse its existence. The data we used made necessary some assumptions and the reliability of official estimates of crime rates was debatable (probably downward biased). We conclude that, at least for Italy, the suggested relationship is unproven: other reasons for the need of legal abortion have been and should be put forward.
Cassini's Test Methodology for Flight Software Verification and Operations
Wang, Eric; Brown, Jay
2007-01-01
The Cassini spacecraft was launched on 15 October 1997 on a Titan IV-B launch vehicle. The spacecraft is comprised of various subsystems, including the Attitude and Articulation Control Subsystem (AACS). The AACS Flight Software (FSW) and its development has been an ongoing effort, from the design, development and finally operations. As planned, major modifications to certain FSW functions were designed, tested, verified and uploaded during the cruise phase of the mission. Each flight software upload involved extensive verification testing. A standardized FSW testing methodology was used to verify the integrity of the flight software. This paper summarizes the flight software testing methodology used for verifying FSW from pre-launch through the prime mission, with an emphasis on flight experience testing during the first 2.5 years of the prime mission (July 2004 through January 2007).

Flight testing a propulsion-controlled aircraft emergency flight control system on an F-15 airplane
Burcham, F. W., Jr.; Burken, John; Maine, Trindel A.
1994-01-01
Flight tests of a propulsion-controlled aircraft (PCA) system on an F-15 airplane have been conducted at the NASA Dryden Flight Research Center. The airplane was flown with all flight control surfaces locked both in the manual throttles-only mode and in an augmented system mode. In the latter mode, pilot thumbwheel commands and aircraft feedback parameters were used to position the throttles. Flight evaluation results showed that the PCA system can be used to land an airplane that has suffered a major flight control system failure safely. The PCA system was used to recover the F-15 airplane from a severe upset condition, descend, and land. Pilots from NASA, U.S. Air Force, U.S. Navy, and McDonnell Douglas Aerospace evaluated the PCA system and were favorably impressed with its capability. Manual throttles-only approaches were unsuccessful. This paper describes the PCA system operation and testing. It also presents flight test results and pilot comments.

The NASA Flying Controls Testbed (FLiC) is a relatively small and inexpensive unmanned aerial vehicle developed specifically to test highly experimental flight control approaches. The most recent version of the FLiC is configured with 16 independent aileron segments, supports the implementation of C-coded experimental controllers, and is capable of fully autonomous flight from takeoff roll to landing, including flight test maneuvers. The test vehicle is basically a modified Army target drone, AN/FQM-117B, developed as part of a collaboration between the Aviation Applied Technology Directorate (AATD) at Fort Eustis, Virginia and NASA Langley Research Center. Several vehicles have been constructed and collectively have flown over 600 successful test flights, including a fully autonomous demonstration at the Association of Unmanned Vehicle Systems International (AUVSI) UAV Demo 2005. Simulations based on wind tunnel data are being used to further develop advanced controllers for implementation and flight test.

Optimal Mission Abort Policy for Systems Operating in a Random Environment.
Levitin, Gregory; Finkelstein, Maxim
2018-04-01
Many real-world critical systems, e.g., aircrafts, manned space flight systems, and submarines, utilize mission aborts to enhance their survivability. Specifically, a mission can be aborted when a certain malfunction condition is met and a rescue or recovery procedure is then initiated. For systems exposed to external impacts, the malfunctions are often caused by the consequences of these impacts. Traditional system reliability models typically cannot address a possibility of mission aborts. Therefore, in this article, we first develop the corresponding methodology for modeling and evaluation of the mission success probability and survivability of systems experiencing both internal failures and external shocks. We consider a policy when a mission is aborted and a rescue procedure is activated upon occurrence of the mth shock. We demonstrate the tradeoff between the system survivability and the mission success probability that should be balanced by the proper choice of the decision variable m. A detailed illustrative example of a mission performed by an unmanned aerial vehicle is presented. © 2017 Society for Risk Analysis.

The principal mechanism for developing orbital debris environment models, is to make observations of larger pieces of debris in the range of several centimeters and greater using radar and optical techniques. For particles that are smaller than this threshold, breakup and migration models of particles to returned surfaces in lower orbit are relied upon to quantify the flux. This reliance on models to derive spatial densities of particles that are of critical importance to spacecraft make the unique nature of the EFT-1's return surface a valuable metric. To this end detailed post-flight inspections have been performed of the returned EFT-1 backshell, and the inspections identified six candidate impact sites that were not present during the pre-flight inspections. This paper describes the post-flight analysis efforts to characterize the EFT-1 mission craters. This effort included ground based testing to understand small particle impact craters in the thermal protection material, the pre- and post-flight inspection, the crater analysis using optical, X-ray computed tomography (CT) and scanning electron microscope (SEM) techniques, and numerical simulations.

UAS-NAS Flight Test Series 3: Test Environment Report
Hoang, Ty; Murphy, Jim; Otto, Neil
2016-01-01
The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration in the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability (SSI), Human Systems Integration (HSI), and Communications (Comm), and Certification to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Detect and Avoid (DAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project is conducting a series of human-in-the-loop (HITL) and flight test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity, and

The Orion Multi-Purpose Crew Vehicle (MPCV) Reaction Control System (RCS) is critical to guide the vehicle along the desired trajectory during re--entry. However, this system has a significant impact on the convective heating environment to the spacecraft. Heating augmentation from the jet interaction (JI) drives thermal protection system (TPS) material selection and thickness requirements for the spacecraft. This paper describes the heating environment from the RCS on the afterbody of the Orion MPCV during Orion's first flight test, Exploration Flight Test 1 (EFT-1). These jet plumes interact with the wake of the crew capsule and cause an increase in the convective heating environment. Not only is there widespread influence from the jet banks, there may also be very localized effects. The firing history during EFT-1 will be summarized to assess which jet bank interaction was measured during flight. Heating augmentation factors derived from the reconstructed flight data will be presented. Furthermore, flight instrumentation across the afterbody provides the highest spatial resolution of the region of influence of the individual jet banks of any spacecraft yet flown. This distribution of heating augmentation across the afterbody will be derived from the flight data. Additionally, trends with possible correlating parameters will be investigated to assist future designs and ground testing programs. Finally, the challenges of measuring JI, applying this data to future flights and lessons learned will be discussed.
Estimating the efficacy of medical abortion.
Trussell, J; Ellertson, C
1999-09-01
Comparisons of the efficacy of different regimens of medical abortion are difficult because of the widely varying protocols (even for testing identical regimens), divergent definitions of success and failure, and lack of a standard method of analysis. In this article we review the current efficacy literature on medical abortion, highlighting some of the most important differences in the way that efficacy has been analyzed. We then propose a standard conceptual approach and the accompanying statistical methods for analyzing clinical trials of medical abortion and to explain how clinical investigators can implement this approach. Our review reveals that research on the efficacy of medical abortion has closely followed the conceptual model used for analysis of surgical abortion. The problem, however, is that, whereas surgical abortion is a discrete event occurring in the space of a few minutes or less, medical abortion is a process typically lasting from several days to several weeks. In this process, two events may occur that are not possible with surgical abortion. First, the woman can opt out of the process before a fair determination of efficacy can be made. Second, the process of medical abortion allows time for surgical interventions that may be convenient for the clinician but not strictly necessary from a medical perspective. Another difference from surgical abortions is that, for medical abortions, different medical abortion protocols specify different waiting periods, giving the drugs less time to work in some studies than in others before a determination of efficacy is made. We argue that, when analyzing efficacy of medical abortion, researchers should abandon their close reliance on the analogy to surgical abortion. In fact, medical abortion is more appropriately analyzed by life table procedures developed for the study of another fertility regulation technology; contraception. As with medical abortion, a woman initiating use of a contraceptive method can

Abortion legalized: challenges ahead.
Singh, M; Jha, R
2007-01-01
To see whether advocacy for abortion law and comprehensive abortion care (CAC) sites after legalization of abortion in Nepal is adequate among educated people (above school leaving certificate). 150 participants were assigned randomly who agreed to be in the survey and were given structured questionnaires to find out their perception of abortion and CAC sites. Majority know abortion is legalized and majority have positive attitude about legalization of abortion, however majority are not aware of abortion service in CAC sites and none knew the cost of abortion service. Proper and adequate advocacy of the new abortion law and CAC service is essential.
The politicization of abortion and the evolution of abortion counseling.
Joffe, Carole
2013-01-01
The field of abortion counseling originated in the abortion rights movement of the 1970s. During its evolution to the present day, it has faced significant challenges, primarily arising from the increasing politicization and stigmatization of abortion since legalization. Abortion counseling has been affected not only by the imposition of antiabortion statutes, but also by the changing needs of patients who have come of age in a very different era than when this occupation was first developed. One major innovation--head and heart counseling--departs in significant ways from previous conventions of the field and illustrates the complex and changing political meanings of abortion and therefore the challenges to abortion providers in the years following Roe v Wade.
Conceptualising abortion stigma
Kumar, Anuradha; Hessini, Leila; Mitchell, Ellen M. H.
2009-01-01
Abortion stigma is widely acknowledged in many countries, but poorly theorised. Although media accounts often evoke abortion stigma as a universal social fact, we suggest that the social production of abortion stigma is profoundly local. Abortion stigma is neither natural nor 'essential' and relies

This review of abortion history considers sacred and secular practice and traces abortion in the US, the legacy of the 19th century, and the change that occurred in the 20th century. Abortion has been practiced since ancient times, but its legality and availability have been threatened continuously by forces that would denigrate women's fundamental rights. Currently, while efforts to decrease the need for abortion through contraception and education continue, access to abortion remains crucial for the well-being of millions of women. That access will never be secure until profound changes occur in the whole society. Laws that prohibit absolutely the practice of abortion are a relatively recent development. In the early Roman Catholic church, abortion was permitted for male fetuses in the first 40 days of pregnancy and for female fetuses in the first 80-90 days. Not until 1588 did Pope Sixtus V declare all abortion murder, with excommunication as the punishment. Only 3 years later a new pope found the absolute sanction unworkable and again allowed early abortions. 300 years would pass before the Catholic church under Pius IX again declared all abortion murder. This standard, declared in 1869, remains the official position of the church, reaffirmed by the current pope. In 1920 the Soviet Union became the 1st modern state formally to legalize abortion. In the early period after the 1917 revolution, abortion was readily available in state operated facilities. These facilities were closed and abortion made illegal when it became clear that the Soviet Union would have to defend itself against Nazi Germany. After World War II women were encouraged to enter the labor force, and abortion once again became legal. The cases of the Catholic church and the Soviet Union illustrate the same point. Abortion legislation has never been in the hands of women. In the 20th century, state policy has been determined by the rhythms of economic and military expansion, the desire for cheap
Abortion trends from 1996 to 2011 in Estonia: special emphasis on repeat abortion
2014-01-01
Background The study aimed to describe the overall and age-specific trends of induced abortions from 1996 to 2011 with an emphasis on socio-demographic characteristics and contraceptive use of women having had repeat abortions in Estonia. Methods Data were retrieved from the Estonian Medical Birth and Abortion Registry and Statistics Estonia. Total induced abortion numbers, rates, ratios and age-specific rates are presented for 1996–2011. The percentage change in the number of repeat abortions within selected socio-demographic subgroups, contraception use and distribution of induced abortions among Estonians and non-Estonians for the first, second, third, fourth and subsequent abortions were calculated for the periods 1996–2003 and 2004–2011. Results Observed trends over the 16-year study period indicated a considerable decline in induced abortions with a reduction in abortion rate of 57.1%, which was mainly attributed to younger cohorts. The percentage of women undergoing repeat abortions fell steadily from 63.8% during 1996–2003 to 58.0% during 2004–2011. The percentage of women undergoing repeat abortions significantly decreased over the 16 years within all selected socio-demographic subgroups except among women with low educational attainment and students. Within each time period, a greater percentage of non-Estonians than Estonians underwent repeat abortions and obtained third and subsequent abortions. Most women did not use any contraceptive method prior to their first or subsequent abortion. Conclusion A high percentage of women obtaining repeat abortions reflects a high historical abortion rate. If current trends continue, a rapid decline in repeat abortions may be predicted. To decrease the burden of sexual ill health, routine contraceptive counselling, as standard care in the abortion process, should be seriously addressed with an emphasis on those groups - non-Estonians, women with lower educational attainment, students and women with children

To find the latest and most accurate information on aspects of induced abortion. A literature survey was carried out in which five aspects of abortion were scrutinised: risk to life, risk of breast cancer, risk to mental health, risk to future fertility, and fetal pain. Abortion is clearly safer than childbirth. There is no evidence of an association between abortion and breast cancer. Women who have abortions are not at increased risk of mental health problems over and above women who deliver an unwanted pregnancy. There is no negative effect of abortion on a woman's subsequent fertility. It is not possible for a fetus to perceive pain before 24 weeks' gestation. Misinformation on abortion is widespread. Literature and websites are cited to demonstrate how data have been manipulated and misquoted or just ignored. Citation of non-peer reviewed articles is also common. Mandates insisting on provision of inaccurate information in some US State laws are presented. Attention is drawn to how women can be misled by Crisis Pregnancy Centres. There is extensive promulgation of misinformation on abortion by those who oppose abortion. Much of this misinformation is based on distorted interpretation of the scientific literature.

Aerodynamic Flight-Test Results for the Adaptive Compliant Trailing Edge
Cumming, Stephen B.; Smith, Mark S.; Ali, Aliyah N.; Bui, Trong T.; Ellsworth, Joel C.; Garcia, Christian A.
2016-01-01
The aerodynamic effects of compliant flaps installed onto a modified Gulfstream III airplane were investigated. Analyses were performed prior to flight to predict the aerodynamic effects of the flap installation. Flight tests were conducted to gather both structural and aerodynamic data. The airplane was instrumented to collect vehicle aerodynamic data and wing pressure data. A leading-edge stagnation detection system was also installed. The data from these flights were analyzed and compared with predictions. The predictive tools compared well with flight data for small flap deflections, but differences between predictions and flight estimates were greater at larger deflections. This paper describes the methods used to examine the aerodynamics data from the flight tests and provides a discussion of the flight-test results in the areas of vehicle aerodynamics, wing sectional pressure coefficient profiles, and air data.
Flight test of the X-29A at high angle of attack: Flight dynamics and controls
Bauer, Jeffrey E.; Clarke, Robert; Burken, John J.
1995-01-01
The NASA Dryden Flight Research Center has flight tested two X-29A aircraft at low and high angles of attack. The high-angle-of-attack tests evaluate the feasibility of integrated X-29A technologies. More specific objectives focus on evaluating the high-angle-of-attack flying qualities, defining multiaxis controllability limits, and determining the maximum pitch-pointing capability. A pilot-selectable gain system allows examination of tradeoffs in airplane stability and maneuverability. Basic fighter maneuvers provide qualitative evaluation. Bank angle captures permit qualitative data analysis. This paper discusses the design goals and approach for high-angle-of-attack control laws and provides results from the envelope expansion and handling qualities testing at intermediate angles of attack. Comparisons of the flight test results to the predictions are made where appropriate. The pitch rate command structure of the longitudinal control system is shown to be a valid design for high-angle-of-attack control laws. Flight test results show that wing rock amplitude was overpredicted and aileron and rudder effectiveness were underpredicted. Flight tests show the X-29A airplane to be a good aircraft up to 40 deg angle of attack.
Population Group Abortion Rates and Lifetime Incidence of Abortion: United States, 2008-2014.
Jones, Rachel K; Jerman, Jenna
2017-12-01
To assess the prevalence of abortion among population groups and changes in rates between 2008 and 2014. We used secondary data from the Abortion Patient Survey, the American Community Survey, and the National Survey of Family Growth to estimate abortion rates. We used information from the Abortion Patient Survey to estimate the lifetime incidence of abortion. Between 2008 and 2014, the abortion rate declined 25%, from 19.4 to 14.6 per 1000 women aged 15 to 44 years. The abortion rate for adolescents aged 15 to 19 years declined 46%, the largest of any group. Abortion rates declined for all racial and ethnic groups but were larger for non-White women than for non-Hispanic White women. Although the abortion rate decreased 26% for women with incomes less than 100% of the federal poverty level, this population had the highest abortion rate of all the groups examined: 36.6. If the 2014 age-specific abortion rates prevail, 24% of women aged 15 to 44 years in that year will have an abortion by age 45 years. The decline in abortion was not uniform across all population groups.
Development of a flight software testing methodology
Mccluskey, E. J.; Andrews, D. M.
1985-01-01
The research to develop a testing methodology for flight software is described. An experiment was conducted in using assertions to dynamically test digital flight control software. The experiment showed that 87% of typical errors introduced into the program would be detected by assertions. Detailed analysis of the test data showed that the number of assertions needed to detect those errors could be reduced to a minimal set. The analysis also revealed that the most effective assertions tested program parameters that provided greater indirect (collateral) testing of other parameters. In addition, a prototype watchdog task system was built to evaluate the effectiveness of executing assertions in parallel by using the multitasking features of Ada.
[Demand for abortion. Pre-abortion discussion].
Guiol, L
1994-03-01
The preabortion interview required by French law takes place between the medical consultation and the aspiration or administration of RU-486. The three marriage counselors at the Center for Social Gynecology in Marseilles have each undertaken a course of personal therapy to enable them to understand their own reactions and motivations as a way of improving their effectiveness with clients. The preabortion interview is an opportunity to listen to and support women who may be experiencing anguish, sadness, ambivalence, or aggressivity. Each client determines the content of the interview. Often the reason for the abortion is given, frequently in terms of economic problems, unemployment, or other justification. The women almost always state that they "cannot", not that they "do not want", to continue the pregnancy, as if external circumstances had made their decision. The decision is usually made with little discussion. Young adolescents are often astounded to find themselves pregnant. Among young girls, the pregnancy may represent an appeal to the parents for attention or understanding. Sometimes the abortion represents a repetition or a reminder of some difficult event in the past, such as a previous abortion or the death of a child. Often the abortion exacerbates problems in the couple's relationship. The mother often experiences rejection of the pregnancy by the father as rejection of herself. Repeat abortions raise questions about whether some aspect of counseling was neglected. The abortion request always occasions a great feeling of guilt, both for being pregnant and for refusing the pregnancy. The interview permits the client to express her feelings and may help her make sense of the experience.

To review the status of antiabortion restrictions enacted over the last 5 years in the United States and their impact on abortion services. In recent years, there has been an alarming rise in the number of antiabortion laws enacted across the United States. In total, various states in the union enacted 334 abortion restrictions from 2011 to July 2016, accounting for 30% of all abortion restrictions since the legalization of abortion in 1973. Data confirm, however, that more liberal abortion laws do not increase the number of abortions, but instead greatly decrease the number of abortion-related deaths. Several countries including Romania, South Africa and Nepal have seen dramatic decreases in maternal mortality after liberalization of abortion laws, without an increase in the total number of abortions. In the United States, abortions are incredibly safe with very low rates of complications and a mortality rate of 0.7 per 100 000 women. With increasing abortion restrictions, maternal mortality in the United States can be expected to rise over the coming years, as has been observed in Texas recently. Liberalization of abortion laws saves women's lives. The rising number of antiabortion restrictions will ultimately harm women and their families.

An emergency flight control system using only engine thrust, called Propulsion-Controlled Aircraft (PCA), has been developed and flight tested on an MD-11 airplane. In this thrust-only control system, pilot flight path and track commands and aircraft feedback parameters are used to control the throttles. The PCA system was installed on the MD-11 airplane using software modifications to existing computers. Flight test results show that the PCA system can be used to fly to an airport and safely land a transport airplane with an inoperative flight control system. In up-and-away operation, the PCA system served as an acceptable autopilot capable of extended flight over a range of speeds and altitudes. The PCA approaches, go-arounds, and three landings without the use of any non-nal flight controls have been demonstrated, including instrument landing system-coupled hands-off landings. The PCA operation was used to recover from an upset condition. In addition, PCA was tested at altitude with all three hydraulic systems turned off. This paper reviews the principles of throttles-only flight control; describes the MD-11 airplane and systems; and discusses PCA system development, operation, flight testing, and pilot comments.

An automated flight test management system (ATMS) and its use to develop a rapid-prototyping flight research facility for artificial intelligence (AI) based flight systems concepts are described. The ATMS provides a flight test engineer with a set of tools that assist in flight planning and simulation. This system will be capable of controlling an aircraft during the flight test by performing closed-loop guidance functions, range management, and maneuver-quality monitoring. The rapid-prototyping flight research facility is being developed at the Dryden Flight Research Facility of the NASA Ames Research Center (Ames-Dryden) to provide early flight assessment of emerging AI technology. The facility is being developed as one element of the aircraft automation program which focuses on the qualification and validation of embedded real-time AI-based systems.
Public funding of abortions and abortion counseling for poor women.
Edwards, R B
1997-01-01
This essay seeks to reveal the weakness in arguments against public funding of abortions and abortion counseling in the US based on economic, ethico-religious, anti-racist, and logical-consistency objections and to show that public funding of abortion is strongly supported by appeals to basic human rights, to freedom of speech, to informed consent, to protection from great harm, to justice, and to equal protection under the law. The first part of the article presents the case against public funding with detailed considerations of the economic argument, the ethico/religious argument, the argument that such funding supports racist genocide or eugenic quality control, and arguments that a logical inconsistency exists between the principles used to justify the legalization of abortions and arguments for public funding. The second part of the article presents the case for public funding by discussing the spending of public funds on morally offensive programs, arguments for public funding of abortion counseling for the poor, and arguments for public funding of abortions for the poor. It is concluded that it is morally unacceptable and rationally unjustifiable to refuse to expend public funds for abortions for low income women, because after all most money for legal abortions for the poor comes from welfare payments made to women. If conservative forces want to insure that no public funds pay for abortions, they must stop all welfare payments to pregnant women.

Reproductive governance operates through calculating demographic statistics that offer selective truths about reproductive practices, bodies, and subjectivities. Post-abortion care, a global reproductive health intervention, represents a transnational reproductive regime that establishes motherhood as women's primary legitimate reproductive status. Drawing on ethnographic fieldwork conducted in Senegal between 2010 and 2011, I illustrate how post-abortion care accomplishes reproductive governance in a context where abortion is prohibited altogether and the US is the primary bilateral donor of population aid. Reproductive governance unfolds in hospital gynecological wards and the national health information system through the mobilization and interpretation of post-abortion care data. Although health workers search women's bodies and behavior for signs of illegal abortion, they minimize police intervention in the hospital by classifying most post-abortion care cases as miscarriage. Health authorities deploy this account of post-abortion care to align the intervention with national and global maternal health policies that valorize motherhood. Although post-abortion care offers life-saving care to women with complications of illegal abortion, it institutionalizes abortion stigma by scrutinizing women's bodies and masking induced abortion within and beyond the hospital. Post-abortion care reinforces reproductive inequities by withholding safe, affordable obstetric care from women until after they have resorted to unsafe abortion.

A Flight Test Engineering Database Management System (FTE DBMS) was designed and implemented at the NASA Dryden Flight Research Facility. The X-29 Forward Swept Wing Advanced Technology Demonstrator flight research program was chosen for the initial system development and implementation. The FTE DBMS greatly assisted in planning and 'mass production' card preparation for an accelerated X-29 research program. Improved Test Plan tracking and maneuver management for a high flight-rate program were proven, and flight rates of up to three flights per day, two times per week were maintained.

To inform improvements in safe abortion and post-abortion family planning (PAFP) services, this study aimed to explore the pathways, decision-making, experiences and preferences of women receiving safe abortion and post-abortion family planning (PAFP) at private clinics in western Kenya. We conducted semi-structured interviews with 22 women who had recently used a safe abortion service from a private clinic. Interviews explored abortion-seeking behaviour and decision-making, abortion experience, use and knowledge of contraception, experience of PAFP counselling, and perceived facilitators of and challenges to family planning use. Respondents discovered their pregnancies due to physical symptoms, which were confirmed using pregnancy testing kits, often purchased from pharmacies. Respondents usually discussed their abortion decision with their partner, and, sometimes, carefully-selected friends or family members. Some reported being referred to private clinics for abortion services directly from other providers. Others had more complex pathways, first seeking care from unsafe providers, trying to self-induce abortion, being turned away from alternative safe facilities that were closed or too busy, or taking time to gather financial resources to pay for care. Participants wanted to use abortion services at facilities reputed for being accessible, clean, medically safe, and offering quick, respectful, private and courteous services. Awareness of reputable clinics was gained through personal experience, and recommendations from contacts and other health providers. Most participants had previously used contraception, with some reports of incorrect use and many reports of side effects. PAFP counselling was valued by clients, but some accounts suggested the counselling lacked comprehensive information. Many women chose contraception immediately following PAFP counselling; but others wanted to delay decision-making about contraception until the abortion was complete

It is known that, since antiquity, women confronted with an unwanted pregnancy have used abortion as a means of resolving their dilemma. Although undoubtedly widely used in all historical ages, abortion has come to be regarded as an event preferably avoided because of the impact on the women concerned as well as considerations for fetal life. Policies to reduce numbers and rates of abortion must acknowledge certain observations. Criminalization does not prevent abortion but increases maternal risks. A society's 'openness' in discussing sexual matters inversely correlates with abortion rates. Correlation between contraceptive use and abortion is also inverse but relates most closely to the efficacy of contraceptive methods used. 'Revolution' in the range of contraceptive methods used will have an equivalent impact on abortion rates. Secondary or emergency contraceptive methods have a considerable role to play in the reduction of abortion numbers. Good sex (and 'relationships') education programs may delay sexual debut, increase contraceptive usage and be associated with reduced abortion. Finally, interaction between socioeconomic factors and the choice between abortion and ongoing pregnancy are complex. Abortion is not necessarily chosen by those least able to support a child financially.

Abortion is the interruption of a dynamic process in a final and irreversible form. The legalization of abortion is applied to human ontogenesis, that is, the development of the human being. However, the embryo that is growing in the uterus is not a human being because a human being is a complex organism with differentiated systems, its own identity and intrinsic autonomy in its process of development. There are basically four levels of the analysis of the problem of abortion: 1) fundamental emotional arguments; 2) profound ignorance of technical and scientific facts; 3) rational positions obfuscated by the dramatic intensity of everyday situations; and 4) the conjunction of deliberated position where culpability is avoided with solidarity for all subjects of the process with a socially oriented view. The phenomenon of abortion from an epidemiological point of view summons the facts with which it is associated: poverty, illiteracy, shortage or lack of community health resources, absence of centers for adolescents, degradation of the environment, and precariousness of employment.
[Use of contraception and reasons for choosing abortion among abortion applicants].
Hansen, S K; Birkebaek, J S; Husfeldt, C; Munck, C B; Nøddebo, S M; Petersson, B H
1996-10-07
The object of this study was to describe a group of women applying for legal abortion in relation to their use of contraception and reasons for choosing an abortion. During a period of 13 months (1991-92) a questionnaire was distributed to women applying for legal abortion at Hillerød Hospital in Denmark. Three hundred and thirty-nine women participated. Fifty-nine percent of the women had become pregnant although they had used contraception. As seen in other studies, women still state demographic factors as their most important reasons for choosing an abortion. Women with two or more children do not want to have more children. Single women do not want children without being in a stable relationship. Furthermore occupation and education were frequently stated as important reasons for having an abortion. Economy and housing were not main reasons but contributory factors. Thirty percent of the women expressed ambivalence about the choice of abortion at the time when the abort was due.
[Bioethics and abortion. Debate].
Diniz, D; Gonzalez Velez, A C
1998-06-01
Although abortion has been the most debated of all issues analyzed in bioethics, no moral consensus has been achieved. The problem of abortion exemplifies the difficulty of establishing social dialogue in the face of distinct moral positions, and of creating an independent academic discussion based on writings that are passionately argumentative. The greatest difficulty posed by the abortion literature is to identify consistent philosophical and scientific arguments amid the rhetorical manipulation. A few illustrative texts were selected to characterize the contemporary debate. The terms used to describe abortion are full of moral meaning and must be analyzed for their underlying assumptions. Of the four main types of abortion, only 'eugenic abortion', as exemplified by the Nazis, does not consider the wishes of the woman or couple--a fundamental difference for most bioethicists. The terms 'selective abortion' and 'therapeutic abortion' are often confused, and selective abortion is often called eugenic abortion by opponents. The terms used to describe abortion practitioners, abortion opponents, and the 'product' are also of interest in determining the style of the article. The video entitled "The Silent Scream" was a classic example of violent and seductive rhetoric. Its type of discourse, freely mixing scientific arguments and moral beliefs, hinders analysis. Within writings about abortion three extreme positions may be identified: heteronomy (the belief that life is a gift that does not belong to one) versus reproductive autonomy; sanctity of life versus tangibility of life; and abortion as a crime versus abortion as morally neutral. Most individuals show an inconsistent array of beliefs, and few groups or individuals identify with the extreme positions. The principal argument of proponents of legalization is respect for the reproductive autonomy of the woman or couple based on the principle of individual liberty, while heteronomy is the main principle of
The ethics of abortions for fetuses with congenital abnormalities.
Jotkowitz, Alan; Zivotofsky, Ari Z
2010-10-01
Abortion remains a highly contentious moral issue, with the debate usually framed as a battle between the fetus's right to life and the woman's right to choose. Often overlooked in this debate is the impact of the concurrent legalization of abortion and the development of new prenatal screening tests on the birth prevalence of many inherited diseases. Most proponents of abortion support abortion for fetuses with severe congenital diseases, but there has unfortunately been, in our opinion, too little debate over the moral appropriateness of abortion for much less severe congenital conditions such as Down's syndrome, deafness, and dwarfism. Due to scientific advances, we are looking at a future in which prenatal diagnosis will be safer and more accurate, raising the specter, and the concomitant ethical concerns, of wholesale abortions. Herein, we present a reframing of the abortion debate that better encompasses these conditions and offers a more nuanced position. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

We use unique data on abortions performed in New York State from 1971–1975 to demonstrate that women travelled hundreds of miles for a legal abortion before Roe. A100- mile increase in distance for women who live approximately 183 miles from New York was associated with a decline in abortion rates of 12.2 percent whereas the same change for women who lived 830 miles from New York lowered abortion rates by 3.3 percent. The abortion rates of nonwhites were more sensitive to distance than those of whites. We found a positive and robust association between distance to the nearest abortion provider and teen birth rates but less consistent estimates for other ages. Our results suggest that even if some states lost all abortion providers due to legislative policies, the impact on population measures of birth and abortion rates would be small as most women would travel to states with abortion services.

Effects of price and availability on abortion demand.
Gohmann, S F; Ohsfeldt, R L
1993-10-01
This study explained the variation in US state abortion demand due to the price of services, the net of insurance cost of birth services, the ability to pay, contraceptive use, individual attitudes regarding abortion, and government policy affecting cost of benefits of terminating an unintended pregnancy or of carrying to birth. The empirical model uses pooled data from 48 states for 1982, 1984, 1985, and 1987. Prices are deflated to 1977 dollars. Another two-staged least squares model is based on cross-sectional state level data for 1985. The dependent variable is the log of abortion per 1000 pregnancies. Other variables pertain to income, education, labor force, family planning, tax, aid to families with dependent children, religion, and abortion-related measures. The results of the cross-sectional analysis are consistent with Medoff's and Garbacz's findings. The estimated coefficient of per capita income is positive with a point elasticity ranging from 0.62 to 1.0. The model with the most complete specifications has an abortion price elasticity range from -0.75 to -1.3 and is statistically significant when religion measures are excluded. The Hausman test shows the pro-choice variable significantly correlated with the error term. The net price of birth services is not statistically significant. Catholic religion and no religion are only significant when the abortion provider variable is excluded. The suggestion is that the effect of Catholicism is ambiguous. In the pooled analysis, the fixed effects model is used to control for abortion attitudes and other unobserved factors. Abortion demand includes abortion per 1000 pregnancies, the ratio of abortions to pregnancies, and the logarithm of abortions per 1000 pregnancies. Higher income is associated with a higher abortion rate and elasticities of 0.76 and 0.35 and is associated with a higher pregnancy rate. The abortion ratio is found to be elastic with respect to price, and price elasticities are sensitive to
Trends of abortion complications in a transition of abortion law revisions in Ethiopia.

2009-03-01
Evidence from developed countries has shown that abortion-related mortality and morbidity has decreased with the liberalization of the abortion law. This study aimed to assess the trend of hospital-based abortion complications during the transition of legalization in Ethiopia in May 2005. Medical records of women with abortion complications from 2003 to 2007 were reviewed (n = 773). Abortion and its complications with regard to legalization were described by rates and ratios, and predictors of fatal outcomes were analyzed by logistic regression. The overall and abortion-related maternal mortality ratios (AMMRs) showed a non-statistically significant downward trend over the 5-year period. However, the case fatality rate of abortion increased from 1.1% in 2003 to 3.6% in 2007. Late gestational age, history of interference and presenting after new abortion legislation passed have been found to be significant predictors of mortality. Decreased trends of abortion ratio and the AMMR were identified, but the severity of abortion complications and the case fatality rate increased during the transition of legal revision.

Accurate measurement of induced abortion levels has proven difficult in many parts of the world. Health care workers and policymakers need information on the incidence of both legal and illegal induced abortion to provide the needed services and to reduce the negative impact of unsafe abortion on women's health. Numbers and rates of induced abortions were estimated from four sources: official statistics or other national data on legal abortions in 57 countries; estimates based on population surveys for two countries without official statistics; special studies for 10 countries where abortion is highly restricted; and worldwide and regional estimates of unsafe abortion from the World Health Organization. Approximately 26 million legal and 20 million illegal abortions were performed worldwide in 1995, resulting in a worldwide abortion rate of 35 per 1,000 women aged 15-44. Among the subregions of the world, Eastern Europe had the highest abortion rate (90 per 1,000) and Western Europe to the lowest rate (11 per 1,000). Among countries where abortion is legal without restriction as to reason, the highest abortion rate, 83 per 1,000, was reported for Vietnam and the lowest, seven per 1,000, for Belgium and the Netherlands. Abortion rates are no lower overall in areas where abortion is generally restricted by law (and where many abortions are performed under unsafe conditions) than in areas where abortion is legally permitted. Both developed and developing countries can have low abortion rates. Most countries, however, have moderate to high abortion rates, reflecting lower prevalence and effectiveness of contraceptive use. Stringent legal restrictions do not guarantee a low abortion rate.
[[Abortion: An Unforgivable Sin?].
Lalli, Chiara
Abortion has become something to hide, something you can't tell other people, something you have to expiate forever. Besides, abortion is more and more difficult to achieve because of the raising average of consciencious objection (from 70 to 90% of health care providers are conscientious objectors, 2014 data, Ministero della Salute) and illegal abortion is "coming back"from the 70s, when abortion was a crime (Italian law n. 194/1978). Abortion is often blamed as a murder, an unforgivenable sin, even as genocide. Silence against shouting "killers!" to women who are going to have an abortion: this is a common actual scenario. Why is it so difficult to discuss and even to mention abortion?
Design and flight testing of a nullable compressor face rake
Holzman, J. K.; Payne, G. A.
1973-01-01
A compressor face rake with an internal valve arrangement to permit nulling was designed, constructed, and tested in the laboratory and in flight at the NASA Flight Research Center. When actuated by the pilot in flight, the nullable rake allowed the transducer zero shifts to be determined and then subsequently removed during data reduction. Design details, the fabrication technique, the principle of operation, brief descriptions of associated digital zero-correction programs and the qualification tests, and test results are included. Sample flight data show that the zero shifts were large and unpredictable but could be measured in flight with the rake. The rake functioned reliably and as expected during 25 hours of operation under flight environmental conditions and temperatures from 230 K (-46 F) to greater than 430 K (314 F). The rake was nulled approximately 1000 times. The in-flight zero-shift measurement technique, as well as the rake design, was successful and should be useful in future applications, particularly where accurate measurements of both steady-state and dynamic pressures are required under adverse environmental conditions.
Space Shuttle Boundary Layer Transition Flight Experiment Ground Testing Overview
Berger, Karen T.; Anderson, Brian P.; Campbell, Charles H.
2014-01-01
In support of the Boundary Layer Transition (BLT) Flight Experiment (FE) Project in which a manufactured protuberance tile was installed on the port wing of Space Shuttle Orbiter Discovery for STS-119, STS- 128, STS-131 and STS-133 as well as Space Shuttle Orbiter Endeavour for STS-134, a significant ground test campaign was completed. The primary goals of the test campaign were to provide ground test data to support the planning and safety certification efforts required to fly the flight experiment as well as validation for the collected flight data. These test included Arcjet testing of the tile protuberance, aerothermal testing to determine the boundary layer transition behavior and resultant surface heating and planar laser induced fluorescence (PLIF) testing in order to gain a better understanding of the flow field characteristics associated with the flight experiment. This paper provides an overview of the BLT FE Project ground testing. High-level overviews of the facilities, models, test techniques and data are presented, along with a summary of the insights gained from each test.

Telling stories about abortion: abortion-related plots in American film and television, 1916-2013.
Sisson, Gretchen; Kimport, Katrina
2014-05-01
Popular discourse on abortion in film and television assumes that abortions are under- and misrepresented. Research indicates that such representations influence public perception of abortion care and may play a role in the production of social myths around abortion, with consequences for women's experience of abortion. To date, abortion plotlines in American film and television have not been systematically tracked and analyzed. A comprehensive online search was conducted to identify all representations of pregnancy decision making and abortion in American film and television through January 2013. Search results were coded for year, pregnancy decision and mortality outcome. A total of 310 plotlines were identified, with an overall upward trend over time in the number of representations of abortion decision making. Of these plotlines, 173 (55.8%) resulted in abortion, 80 (25.8%) in parenting, 13 (4.2%) in adoption and 21 (6.7%) in pregnancy loss, and 16 (5.1%) were unresolved. A total of 13.5% (n=42) of stories ended with the death of the woman who considered an abortion, whether or not she obtained one. Abortion-related plotlines occur more frequently than popular discourse assumes. Year-to-year variation in frequency suggests an interactive relationship between media representations, cultural attitudes and policies around abortion regulation, consistent with cultural theory of the relationship between media products and social beliefs. Patterns of outcomes and rates of mortality are not representative of real experience and may contribute to social myths around abortion. The narrative linking of pregnancy termination with mortality is of particular note, supporting the social myth associating abortion with death. This analysis empirically describes the number of abortion-related plotlines in American film and television. It contributes to the systematic evaluation of the portrayal of abortion in popular culture and provides abortion care professionals and
Design and Testing of Flight Control Laws on the RASCAL Research Helicopter
Frost, Chad R.; Hindson, William S.; Moralez. Ernesto, III; Tucker, George E.; Dryfoos, James B.
2001-01-01
Two unique sets of flight control laws were designed, tested and flown on the Army/NASA Rotorcraft Aircrew Systems Concepts Airborne Laboratory (RASCAL) JUH-60A Black Hawk helicopter. The first set of control laws used a simple rate feedback scheme, intended to facilitate the first flight and subsequent flight qualification of the RASCAL research flight control system. The second set of control laws comprised a more sophisticated model-following architecture. Both sets of flight control laws were developed and tested extensively using desktop-to-flight modeling, analysis, and simulation tools. Flight test data matched the model predicted responses well, providing both evidence and confidence that future flight control development for RASCAL will be efficient and accurate.
Abortion law across Australia--A review of nine jurisdictions.
de Costa, Caroline; Douglas, Heather; Hamblin, Julie; Ramsay, Philippa; Shircore, Mandy
2015-04-01
This article reviews the current legal status of abortion in Australia and its implications. Australian abortion law has been a matter for the states since before Federation. In the years since Federation there have been significant reforms and changes in the abortion laws of some jurisdictions, although not all. Across Australia there are now nine sets of laws, state and Commonwealth, concerned with abortion. The test of a lawful abortion varies greatly across jurisdictions. In a number of states and territories, it is necessary to establish a serious risk to the physical or mental health of the woman if the pregnancy was to continue. In some cases, the certification of two doctors is required, particularly for abortions at later gestations. There are also physical restrictions on access, such as in South Australia and the Northern Territory where abortion must take place in a hospital. Only in the ACT has abortion been removed from the criminal law altogether. Variations in the law and restrictions arising from these are not consistent with the aims and provision of the universal, accessible health care system aspired to in Australia. There is an urgent need for overall reform and the introduction of uniformity to Australia's abortion laws, including removal of abortion from the criminal law. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.
Flight Test Results for the F-16XL With a Digital Flight Control System
Stachowiak, Susan J.; Bosworth, John T.
2004-01-01
In the early 1980s, two F-16 airplanes were modified to extend the fuselage length and incorporate a large area delta wing planform. These two airplanes, designated the F-16XL, were designed by the General Dynamics Corporation (now Lockheed Martin Tactical Aircraft Systems) (Fort Worth, Texas) and were prototypes for a derivative fighter evaluation program conducted by the United States Air Force. Although the concept was never put into production, the F-16XL prototypes provided a unique planform for testing concepts in support of future high-speed supersonic transport aircraft. To extend the capabilities of this testbed vehicle the F-16XL ship 1 aircraft was upgraded with a digital flight control system. The added flexibility of a digital flight control system increases the versatility of this airplane as a testbed for aerodynamic research and investigation of advanced technologies. This report presents the handling qualities flight test results covering the envelope expansion of the F-16XL with the digital flight control system.
Wind and Wake Sensing with UAV Formation Flight: System Development and Flight Testing

sensing data using UAVs in formation flight. This has been achieved and well documented before in manned aircraft but very little work has been done on UAV wake sensing especially during flight testing. This document describes the development and flight testing of small unmanned aerial system (UAS) for wind and wake sensing purpose including a Ground Control Station (GCS) and UAVs. This research can be stated in four major components. Firstly, formation flight was obtained by integrating a formation flight controller on the WVU Phastball Research UAV aircraft platform from the Flight Control Systems Laboratory (FCSL) at West Virginia University (WVU). Second, a new approach to wind estimation using an Unscented Kalman filter (UKF) is discussed along with results from flight data. Third, wake modeling within a simulator and wake sensing during formation flight is shown. Finally, experimental results are used to discuss the "sweet spot" for energy harvesting in formation flight, a novel approach to cooperative wind estimation, and gust suppression control for a follower aircraft in formation flight.

Estimates of the Incidence of Induced Abortion And Consequences of Unsafe Abortion in Senegal
Sedgh, Gilda; Sylla, Amadou Hassane; Philbin, Jesse; Keogh, Sarah; Ndiaye, Salif
2015-01-01
CONTEXT Abortion is highly restricted by law in Senegal. Although women seek care for abortion complications, no national estimate of abortion incidence exists. METHODS Data on postabortion care and abortion in Senegal were collected in 2013 using surveys of a nationally representative sample of 168 health facilities that provide postabortion care and of 110 professionals knowledgeable about abortion service provision. Indirect estimation techniques were applied to the data to estimate the incidence of induced abortion in the country. Abortion rates and ratios were calculated for the nation and separately for the Dakar region and the rest of the country. The distribution of pregnancies by planning status and by outcome was estimated. RESULTS In 2012, an estimated 51,500 induced abortions were performed in Senegal, and 16,700 (32%) resulted in complications that were treated at health facilities. The estimated abortion rate was 17 per 1,000 women aged 15–44 and the abortion ratio was 10 per 100 live births. The rate was higher in Dakar (21 per 1,000) than in the rest of the country (16 per 1,000). Poor women were far more likely to experience abortion complications, and less likely to receive treatment for complications, than nonpoor women. About 31% of pregnancies were unintended, and 24% of unintended pregnancies (8% of all pregnancies) ended in abortion. CONCLUSIONS Unsafe abortion exacts a heavy toll on women in Senegal. Reducing the barriers to effective contraceptive use and ensuring access to postabortion care without the risk of legal consequences may reduce the incidence of and complications from unsafe abortion.

Flight test of a resident backup software system
Deets, Dwain A.; Lock, Wilton P.; Megna, Vincent A.
1987-01-01
A new fault-tolerant system software concept employing the primary digital computers as host for the backup software portion has been implemented and flight tested in the F-8 digital fly-by-wire airplane. The system was implemented in such a way that essentially no transients occurred in transferring from primary to backup software. This was accomplished without a significant increase in the complexity of the backup software. The primary digital system was frame synchronized, which provided several advantages in implementing the resident backup software system. Since the time of the flight tests, two other flight vehicle programs have made a commitment to incorporate resident backup software similar in nature to the system described here.
Framing a 'social problem': Emotion in anti-abortion activists' depiction of the abortion debate.
Ntontis, Evangelos; Hopkins, Nick
2018-02-27
Social psychological research on activism typically focuses on individuals' social identifications. We complement such research through exploring how activists frame an issue as a social problem. Specifically, we explore anti-abortion activists' representation of abortion and the abortion debate's protagonists so as to recruit support for the anti-abortion cause. Using interview data obtained with UK-based anti-abortion activists (N = 15), we consider how activists characterized women having abortions, pro-abortion campaigners, and anti-abortion campaigners. In particular, we consider the varied ways in which emotion featured in the representation of these social actors. Emotion featured in different ways. Sometimes, it was depicted as constituting embodied testament to the nature of reality. Sometimes, it was depicted as blocking the rational appraisal of reality. Our analysis considers how such varied meanings of emotion shaped the characterization of abortion and the abortion debate's protagonists such that anti-abortion activists were construed as speaking for women and their interests. We discuss how our analysis of the framing of issues as social problems complements and extends social psychological analyses of activism. © 2018 The British Psychological Society.

made by the simulation, aerodynamic characteristics and elastic properties of the tow rope were a significant component of the towing system; and the Dryden high-fidelity simulation provided a representative model of the performance of the QF-106 and C-141A airplanes in tow configuration. Total time on tow for the entire project was 5 hours, 34 minutes, and 29 seconds. All six flights were highly productive, and all project objectives were achieved. All three of the project objectives were successfully accomplished. The objectives were: demonstration of towed takeoff, climb-out, and separation of the EXD-01 from the towing aircraft; validation of simulation models of the towed aircraft systems; and development of ground and flight procedures for towing and launching a delta-winged airplane configuration safely behind a transport-type aircraft. NASA Dryden served as the responsible test organization and had flight safety responsibility for the Eclipse project. Dryden also supplied engineering, simulation, instrumentation, range support, research pilots, and chase aircraft for the test series. Dryden personnel also performed the modifications to convert the QF-106 into the piloted EXD-01 aircraft. During the early flight phase of the project, Tracor, Inc. provided maintenance and ground support for the two QF-106 airplanes. The Air Force Flight Test Center (AFFTC), Edwards, California, provided the C-141A transport aircraft for the project, its flight and engineering support, and the aircrew. Kelly Space and Technology provided the modification design and fabrication of the hardware that was installed on the EXD-01 aircraft. Kelly Space and Technology hopes to use the data gleaned from the tow tests to develop a series of low-cost reusable launch vehicles, in particular to gain experience towing delta-wing aircraft having high wing loading, and in general to demonstrate various operational procedures such as ground processing and abort scenarios.

Induced abortion is widely practised in Taiwan; however, it had been illegal until 1985. It was of interest to investigate induced abortion practices in Taiwan after its legalization in 1985 in order to calculate the prevalence rate and ratio of induced abortion to live births and to pregnancies in Taiwan. A study using questionnaires through personal interviews was conducted on more than seventeen thousand women who attended a family planning service in Taipei metropolitan areas between 1991 and 1992. The reproductive history and sexual behaviour of the subjects were especially focused on during the interviews. Preliminary findings showed that 46% of the women had a history of having had an induced abortion. Among them, 54.8% had had one abortion, 29.7% had had two, and 15.5% had had three or more. The abortion ratio was 379 induced abortions per 1,000 live births and 255 per 1,000 pregnancies. The abortion ratio was highest for women younger than 20 years of age, for aboriginal women and for nulliparous women. When logistic regression was used to control for confounding variables, we found that the number of previous live births is the strongest predictor relating to women seeking induced abortion. In addition, a significant positive association exists between increasing number of induced abortions and cervical dysplasia.

Several examples from the past decade of success stories involving the design and flight test of three true X-planes will be described: in particular, X-plane design techniques that relied heavily upon computational fluid dynamics (CFD). Three specific examples chosen from the author s personal experience are presented: the X-36 Tailless Fighter Agility Research Aircraft, the X-45A Unmanned Combat Air Vehicle, and, most recently, the X-48B Blended Wing Body Demonstrator Aircraft. An overview will be presented of the uses of CFD analysis, comparisons and contrasts with wind tunnel testing, and information derived from the CFD analysis that directly related to successful flight test. Some lessons learned on the proper application, and misapplication, of CFD are illustrated. Finally, some highlights of the flight-test results of the three example X-planes will be presented. This overview paper will discuss some of the author s experience with taking an aircraft shape from early concept and three-dimensional modeling through CFD analysis, wind tunnel testing, further refined CFD analysis, and, finally, flight. An overview of the key roles in which CFD plays well during this process, and some other roles in which it does not, are discussed. How wind tunnel testing complements, calibrates, and verifies CFD analysis is also covered. Lessons learned on where CFD results can be misleading are also given. Strengths and weaknesses of the various types of flow solvers, including panel methods, Euler, and Navier-Stokes techniques, are discussed. The paper concludes with the three specific examples, including some flight test video footage of the X-36, the X-45A, and the X-48B.

Flight test trajectory control analysis
Walker, R.; Gupta, N.
1983-01-01
Recent extensions to optimal control theory applied to meaningful linear models with sufficiently flexible software tools provide powerful techniques for designing flight test trajectory controllers (FTTCs). This report describes the principal steps for systematic development of flight trajectory controllers, which can be summarized as planning, modeling, designing, and validating a trajectory controller. The techniques have been kept as general as possible and should apply to a wide range of problems where quantities must be computed and displayed to a pilot to improve pilot effectiveness and to reduce workload and fatigue. To illustrate the approach, a detailed trajectory guidance law is developed and demonstrated for the F-15 aircraft flying the zoom-and-pushover maneuver.

Abortion stigma may cause psychological distress in women who are considering having an abortion or have had one. This phenomenon has been relatively underexplored in low-income women, who may already be at an increased risk for poor abortion-related outcomes because of difficulties accessing timely and safe abortion services. A qualitative study conducted between 2010 and 2013 used semistructured interviews to explore pregnancy intentions among low-income women recruited from six reproductive health clinics in Western Pennsylvania. Transcripts from interviews with 19 participants who were planning to terminate a pregnancy or had had an abortion in the last two weeks were examined through content analysis to identify the range of attitudes they encountered that could contribute to or reflect abortion stigma, the sources of these attitudes and women's responses to them. Women commonly reported that partners, family members and they themselves held antiabortion attitudes. Such attitudes communicated that abortion is morally reprehensible, a rejection of motherhood, rare and thus potentially deviant, detrimental to future fertility and an irresponsible choice. Women reacted to external and internal negative attitudes by distinguishing themselves from other women who obtain abortions, experiencing negative emotions, and concealing or delaying their abortions. Women's reactions to antiabortion attitudes may perpetuate abortion stigma. Further research is needed to inform interventions to address abortion stigma and improve women's abortion experiences.

Hyper-X Mach 7 Scramjet Design, Ground Test and Flight Results
Ferlemann, Shelly M.; McClinton, Charles R.; Rock, Ken E.; Voland, Randy T.
2005-01-01
The successful Mach 7 flight test of the Hyper-X (X-43) research vehicle has provided the major, essential demonstration of the capability of the airframe integrated scramjet engine. This flight was a crucial first step toward realizing the potential for airbreathing hypersonic propulsion for application to space launch vehicles. However, it is not sufficient to have just achieved a successful flight. The more useful knowledge gained from the flight is how well the prediction methods matched the actual test results in order to have confidence that these methods can be applied to the design of other scramjet engines and powered vehicles. The propulsion predictions for the Mach 7 flight test were calculated using the computer code, SRGULL, with input from computational fluid dynamics (CFD) and wind tunnel tests. This paper will discuss the evolution of the Mach 7 Hyper-X engine, ground wind tunnel experiments, propulsion prediction methodology, flight results and validation of design methods.
Effects of abortion legalization in Nepal, 2001-2010.

Full Text Available Abortion was legalized in Nepal in 2002, following advocacy efforts highlighting high maternal mortality from unsafe abortion. We sought to assess whether legalization led to reductions in the most serious maternal health consequences of unsafe abortion.We conducted retrospective medical chart review of all gynecological cases presenting at four large public referral hospitals in Nepal. For the years 2001-2010, all cases of spontaneous and induced abortion complications were identified, abstracted, and coded to classify cases of serious infection, injury, and systemic complications. We used segmented Poisson and ordinary logistic regression to test for trend and risks of serious complications for three time periods: before implementation (2001-2003, early implementation (2004-2006, and later implementation (2007-2010.23,493 cases of abortion complications were identified. A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85. Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75.Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women's health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance of concerted efforts to improve

A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85). Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75). Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women's health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance of concerted efforts to improve access.

Safety test No. S-6, launch pad abort sequential test Phase II: solid propellant fire
International Nuclear Information System (INIS)
Snow, E.C.
1975-08-01
In preparation for the Lincoln Laboratory's LES 8/9 space mission, a series of tests was performed to evaluate the nuclear safety capability of the Multi-Hundred Watt (MHW) Radioisotope Thermoelectric Generator (RTG) to be used to supply power for the satellite. One such safety test is Test No. S-6, Launch Pad Abort Sequential Test. The objective of this test was to subject the RTG and its components to the sequential environments characteristic of a catastrophic launch pad accident to evaluate their capability to contain the 238 PuO 2 fuel. This sequence of environments was to have consisted of the blast overpressure and fragments, followed by the fireball, low velocity impact on the launch pad, and solid propellant fire. The blast overpressure and fragments were subsequently eliminated from this sequence. The procedures and results of Phase II of Test S-6, Solid Propellant Fire are presented. In this phase of the test, a simulant Fuel Sphere Assembly (FSA) and a mockup of a damaged Heat Source Assembly (HSA) were subjected to single proximity solid propellant fires of approximately 10-min duration. Steel was introduced into both tests to simulate the effects of launch pad debris and the solid rocket motor (SRM) casing that might be present in the fire zone. (TFD)
The political economy of abortion in India: cost and expenditure patterns.
Duggal, Ravi
2004-11-01
Access to abortion services is not difficult in India, even in remote areas. Providers of abortion range from traditional birth attendants to auxiliary nurse midwives and pharmacists, unqualified and qualified private doctors, to gynaecologists. Despite a well-defined law, there is a lack of regulation of abortion services or providers, and the cost to women is determined by supply side economics. The state is not a leading provider of abortions; services remain predominantly in the private sector. Abortions in the public sector are free only if the woman accepts some form of contraception; other fees may also be charged. The cost of abortion varies considerably, depending on the number of weeks of pregnancy, the woman's marital status, the method used, type of anaesthesia, whether it is a sex-selective abortion, whether diagnostic tests are carried out, whether the provider is registered and whether hospitalisation is required. A review of existing studies indicates that abortions cost a substantial amount--first trimester abortion averages Rs.500- 1000 and second trimester abortion Rs.2000-3000. Given the number of unqualified providers and with 15-20% of maternal deaths due to unsafe abortions, the costs of unsafe abortions must also be counted. It is imperative for the state to regulate the abortion economy in India, both to rationalise costs and assure safe abortions for women.

To review updates in how abortion care is depicted and analysed though various media outlets: news, television, film, and social media. A surge in recent media-related abortion research has recognized several notable and emerging themes: abortion in the news media is often inappropriately sourced and politically motivated; abortion portrayal in US film and television is frequently misrepresented; and social media has a new and significant role in abortion advocacy. The portrayal of abortion onscreen, in the news, and online through social media has a significant impact on cultural, personal, and political beliefs in the United States. This is an emerging field of research with wide spread potential impact across several arenas: medicine, policy, public health.
Oral contraception following abortion

Abstract Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. However, limited data exist supporting the effective use of OCs postabortion. We conducted this systematic review and meta-analysis in the present study reported immediate administration of OCs or combined OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies. A total of 8 major authorized Chinese and English databases were screened from January 1960 to November 2014. Randomized controlled trials in which patients had undergone medical or surgical abortions were included. Chinese studies that met the inclusion criteria were divided into 3 groups: administration of OC postmedical abortion (group I; n = 1712), administration of OC postsurgical abortion (group II; n = 8788), and administration of OC in combination with traditional Chinese medicine postsurgical abortion (group III; n = 19,707). In total, 119 of 6160 publications were included in this analysis. Significant difference was observed in group I for vaginal bleeding time (P = 0.0001), the amount of vaginal bleeding (P = 0.03), and menstruation recovery period (P abortion (P abortion, and reduce the risk of complications and unintended pregnancies.

Abortion surveillance--United States, 1991.
Koonin, L M; Smith, J C; Ramick, M
1995-05-05
From 1980 through 1991, the number of legal induced abortions reported to CDC remained stable, varying each year by 1969, CDC has compiled abortion data received from 52 reporting areas: 50 states, the District of Columbia, and New York City. In 1991, 1,388,937 abortions were reported--a 2.8% decrease from 1990. The abortion ratio was 339 legal induced abortions per 1,000 live births, and the abortion rate was 24 per 1,000 women 15-44 years of age. Women who were undergoing an abortion were more likely to be young, white, and unmarried; most had had no previous live births and had been obtaining an abortion for the first time. More than half (52%) of all abortions were performed at or before the 8th week of gestation, and 88% were before the 13th week. Younger women (i.e., women may partially account for this decline. An accurate assessment of the number and characteristics of women who obtain abortions in the United States is necessary both to monitor efforts to prevent unintended pregnancy and to identify and reduce preventable causes of morbidity and mortality associated with abortions.
Integrated Test and Evaluation Flight Test 3 Flight Test Plan
Marston, Michael Lawrence
2015-01-01
The desire and ability to fly Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS) is of increasing urgency. The application of unmanned aircraft to perform national security, defense, scientific, and emergency management are driving the critical need for less restrictive access by UAS to the NAS. UAS represent a new capability that will provide a variety of services in the government (public) and commercial (civil) aviation sectors. The growth of this potential industry has not yet been realized due to the lack of a common understanding of what is required to safely operate UAS in the NAS. NASA's UAS Integration into the NAS Project is conducting research in the areas of Separation Assurance/Sense and Avoid Interoperability, Human Systems Integration (HSI), and Communication to support reducing the barriers of UAS access to the NAS. This research is broken into two research themes namely, UAS Integration and Test Infrastructure. UAS Integration focuses on airspace integration procedures and performance standards to enable UAS integration in the air transportation system, covering Sense and Avoid (SAA) performance standards, command and control performance standards, and human systems integration. The focus of Test Infrastructure is to enable development and validation of airspace integration procedures and performance standards, including the integrated test and evaluation. In support of the integrated test and evaluation efforts, the Project will develop an adaptable, scalable, and schedulable relevant test environment capable of evaluating concepts and technologies for unmanned aircraft systems to safely operate in the NAS. To accomplish this task, the Project will conduct a series of Human-in-the-Loop and Flight Test activities that integrate key concepts, technologies and/or procedures in a relevant air traffic environment. Each of the integrated events will build on the technical achievements, fidelity and complexity of the previous tests and

Nurses have opinions about abortion, but because they are health professionals and their opinions are sought as such, they are obligated to understand why they hold certain views. Nurses need to be clear about why they believe as they do, and they must arrive at a point of view in a rational and logical manner. To assist nurses in this task, the ethical issues surrounding abortion are enumerated and clarified. To do this, some of the philosophic and historic approaches to abortion and how a position can be logically argued are examined. At the outset some emotion-laden terms are defined. Abortion is defined as the expulsion of a fetus from the uterus before 28 weeks' gestation, the arbitrarily established time of viability. This discussion is concerned only with induced abortion. Since the beginning of recorded history women have chosen to have abortions. Early Jews and Christians forbade abortion on practical and religious grounds. A human life was viewed as valuable, and there was also the practical consideration of the addition of another person to the population, i.e., more brute strength to do the necessary physical work, defend against enemies, and ensure the continuation of the people. These kinds of pragmatic reasons favoring or opposing abortion have little to do with the Western concept of abortion in genaeral and what is going on in the U.S. today in particular. Discussion of the ethics of abortion must rest on 1 or more of several foundations: whether or not the fetus is a human being; the rights of the pregnant woman as opposed to those of the fetus, and circumstances of horror and hardship that might surround a pregnancy. Viability is relative. Because viability is not a specific descriptive entity, value judgments become part of the determination, both of viability and the actions that might be taken based on that determination. The fetus does not become a full human being at viability. That occurs only at conception or birth, depending on one's view
The Stratified Legitimacy of Abortions.
Kimport, Katrina; Weitz, Tracy A; Freedman, Lori
2016-12-01
Roe v. Wade was heralded as an end to unequal access to abortion care in the United States. However, today, despite being common and safe, abortion is performed only selectively in hospitals and private practices. Drawing on 61 interviews with obstetrician-gynecologists in these settings, we examine how they determine which abortions to perform. We find that they distinguish between more and less legitimate abortions, producing a narrative of stratified legitimacy that privileges abortions for intended pregnancies, when the fetus is unhealthy, and when women perform normative gendered sexuality, including distress about the abortion, guilt about failure to contracept, and desire for motherhood. This stratified legitimacy can perpetuate socially-inflected inequality of access and normative gendered sexuality. Additionally, we argue that the practice by physicians of distinguishing among abortions can legitimate legislative practices that regulate and restrict some kinds of abortion, further constraining abortion access. © American Sociological Association 2016.
Unsafe abortion: the silent scourge.
Grimes, David A
2003-01-01
An estimated 19 million unsafe abortions occur worldwide each year, resulting in the deaths of about 70,000 women. Legalization of abortion is a necessary but insufficient step toward improving women's health. Without skilled providers, adequate facilities and easy access, the promise of safe, legal abortion will remain unfulfilled, as in India and Zambia. Both suction curettage and pharmacological abortion are safe methods in early pregnancy; sharp curettage is inferior and should be abandoned. For later abortions, either dilation and evacuation or labour induction are appropriate. Hysterotomy should not be used. Timely and appropriate management of complications can reduce morbidity and prevent mortality. Treatment delays are dangerous, regardless of their origin. Misoprostol may reduce the risks of unsafe abortion by providing a safer alternative to traditional clandestine abortion methods. While the debate over abortion will continue, the public health record is settled: safe, legal, accessible abortion improves health.

The Soviet legacy of widespread reliance on induced abortion is of critical importance to reproductive trends and policies in post-Soviet nations, especially as they strive to substitute contraception for abortion. Using data from two Demographic and Health Surveys conducted in 1995 and 1999, this study analyzes and compares trends in abortion and contraception, women's attitudes toward abortion, and their perceptions of problems associated with abortion and contraception in Kazakhstan. Despite an overall decline in abortion and an increase in contraceptive use since Kazakhstan's independence in 1991, abortion has remained a prominent part of the country's reproductive culture and practices. This study shows how abortion-related views reflect the long-standing ethnocultural differences between the indigenous Kazakhs and Kazakhstan's residents of European roots, as the latter continue to have significantly higher levels of abortion. The study, however, also reveals the internal diversity among Kazakhs with respect to abortion experiences and views, stemming from decades of the Soviet sociocultural influence in Kazakhstan. In addition, the analysis points to some generational differences in views concerning abortion and contraception. Finally, the study demonstrates parallels in attitudes toward abortion and toward contraception, thereby questioning straightforward assumptions about the replacement of abortion with contraception.

An emergency flight control system that uses only engine thrust, called the propulsion-controlled aircraft (PCA) system, was developed and flight tested on an MD-11 airplane. The PCA system is a thrust-only control system, which augments pilot flightpath and track commands with aircraft feedback parameters to control engine thrust. The PCA system was implemented on the MD-11 airplane using only software modifications to existing computers. Results of a 25-hr flight test show that the PCA system can be used to fly to an airport and safely land a transport airplane with an inoperative flight control system. In up-and-away operation, the PCA system served as an acceptable autopilot capable of extended flight over a range of speeds, altitudes, and configurations. PCA approaches, go-arounds, and three landings without the use of any normal flight controls were demonstrated, including ILS-coupled hands-off landings. PCA operation was used to recover from an upset condition. The PCA system was also tested at altitude with all three hydraulic systems turned off. This paper reviews the principles of throttles-only flight control, a history of accidents or incidents in which some or all flight controls were lost, the MD-11 airplane and its systems, PCA system development, operation, flight testing, and pilot comments.
Second trimester abortions in India.
Dalvie, Suchitra S
2008-05-01
This article gives an overview of what is known about second trimester abortions in India, including the reasons why women seek abortions in the second trimester, the influence of abortion law and policy, surgical and medical methods used, both safe and unsafe, availability of services, requirements for second trimester service delivery, and barriers women experience in accessing second trimester services. Based on personal experiences and personal communications from other doctors since 1993, when I began working as an abortion provider, the practical realities of second trimester abortion and case histories of women seeking second trimester abortion are also described. Recommendations include expanding the cadre of service providers to non-allopathic clinicians and trained nurses, introducing second trimester medical abortion into the public health system, replacing ethacridine lactate with mifepristone-misoprostol, values clarification among providers to challenge stigma and poor treatment of women seeking second trimester abortion, and raising awareness that abortion is legal in the second trimester and is mostly not requested for reasons of sex selection.
On the Wrongfulness of abortion

Full Text Available Abortion is seen as an immoral and unjust act by many. Nonetheless these views are under pressure to conform to the learned opinion on abortion. A variety of prestigious in the field of applied ethics support abortion in one way or another. And it is a dogma of modern liberalism that even if one is personally opposed to abortion, one must accept the neutral solution of its public permissibility. The present article defends the thesis that abortion is immoral and unjust against these contentions. With regards to the moral status of abortion, it argues that the prohibition of abortion is off a piece with the prohibition of killing generally, which is characterized by protecting all human beings equally. With regards to the compatibility of abortion permissibility with liberalism, the article argues that such a compromise is not neutral, but heavily rigged in favor of the interests and world-views of abortion proponents.

As part of the Airborne Subscale Transport Aircraft Research (AirSTAR) project, NASA Langley Research Center (LaRC) has developed a subscaled flying testbed in order to conduct research experiments in support of the goals of NASA s Aviation Safety Program. This research capability consists of three distinct components. The first of these is the research aircraft, of which there are several in the AirSTAR stable. These aircraft range from a dynamically-scaled, twin turbine vehicle to a propeller driven, off-the-shelf airframe. Each of these airframes carves out its own niche in the research test program. All of the airplanes have sophisticated on-board data acquisition and actuation systems, recording, telemetering, processing, and/or receiving data from research control systems. The second piece of the testbed is the ground facilities, which encompass the hardware and software infrastructure necessary to provide comprehensive support services for conducting flight research using the subscale aircraft, including: subsystem development, integrated testing, remote piloting of the subscale aircraft, telemetry processing, experimental flight control law implementation and evaluation, flight simulation, data recording/archiving, and communications. The ground facilities are comprised of two major components: (1) The Base Research Station (BRS), a LaRC laboratory facility for system development, testing and data analysis, and (2) The Mobile Operations Station (MOS), a self-contained, motorized vehicle serving as a mobile research command/operations center, functionally equivalent to the BRS, capable of deployment to remote sites for supporting flight tests. The third piece of the testbed is the test facility itself. Research flights carried out by the AirSTAR team are conducted at NASA Wallops Flight Facility (WFF) on the Eastern Shore of Virginia. The UAV Island runway is a 50 x 1500 paved runway that lies within restricted airspace at Wallops Flight Facility. The
Safety test of an improved multihundred watt FSA: launch abort, solid propellant fire

This safety test consisted of exposing a simulant-fueled Improved Multihundred Watt Fuel Sphere Assembly, containing a Pt-3008 sphere holding the fuel simulant, to a single proximity fire of UTP-3001 solid rocket propellant for 10.5 min. The graphite outside shell sustained only minor abrasion damage. It was covered on one side with a heavy deposit of alumina from the fire mixed with silica from the test bed. The Pt-3008 shell had small amounts of carbon, alumina, and silica deposited on its surface but sustained no other damage. The PT-3008 sphere was not breached, and therefore the fuel sphere assembly would not release fuel in a solid-propellant fire of a launch abort. 12 figures

Although unsafe abortion continues to be a leading cause of maternal mortality in many countries in Asia, the right to safe abortion remains highly stigmatized across the region. The Asia Safe Abortion Partnership, a regional network advocating for safe abortion, produced an animated short film entitled From Unwanted Pregnancy to Safe Abortion to show in conferences, schools and meetings in order to share knowledge about the barriers to safe abortion in Asia and to facilitate conversations on the right to safe abortion. This paper describes the making of this film, its objectives, content, dissemination and how it has been used. Our experience highlights the advantages of using animated films in addressing highly politicized and sensitive issues like abortion. Animation helped to create powerful advocacy material that does not homogenize the experiences of women across a diverse region, and at the same time emphasize the need for joint activities that express solidarity.

Abortion is the termination of pregnancy prior to the 180th day, during which time the fetus is not yet viable outside the womb. Spontaneous abortion is the body's expulsion of a fetus during the 1st months of pregnancy. It is usually not very painful, does not involve much bleeding, and is rarely complicated by infection. Spontaneous abortion is much more frequent at the outset of pregnancy and may occur unnoticed. Its causes are unknown in over half of cases. The most important causes are developmental problems in the products of conception. Causes of spontaneous abortions of maternal etiology are most frequently uterine malposition or malformation. Serious illness in the mother is a less common cause of spontaneous abortion than once believed. Induced abortion is caused by the destruction of a normally implanted and healthy embryo. Its complications are related to the amount of bleeding or the introduction of germs from outside which can spread rapidly. Placental retention is a danger of all induced abortions. Induced abortion is common and in some countries it even creates demographic problems. Abortion is legal in many countries as an expression of the right to choose, but in others it is only legal on therapeutic grounds. Defenders and detractors of abortion have written extensively about it, with some works being sincere and some only tactical. The great majority of moralists are opposed to abortion, while biologists and scientists are divided on the question. The Spanish penal code punishes all persons who cause the death of a fetus or impede the process of gestation. The Catholic Church has considered abortion a homicide and against divine and natural laws. Legal or illegal, it is certain that the number of abortions increases each day. In the face of this reality, the need is for measures to avoid abortion whenever possible. Sex education in schools, full information on contraceptive methods and creation of family planning centers are some means of

An outbreak of abortion affecting multiparous cows was associated with Hobi-like pestivirus infection. Viral RNA and antigens were detected in the tissues of two aborted fetuses. Molecular assays for other common abortogenic agents tested negative. At the genetic level, the Hobi-like pestivirus displayed the closest relatedness to Italian, Australian, and South American viruses, whereas it diverged from the prototype Thai isolate. These findings may have important implications for the pestivi...

The Intelligent Flight Control System (IFCS) project at the NASA Dryden Flight Research Center, Edwards AFB, CA, has been investigating the use of neural network based adaptive control on a unique NF-15B test aircraft. The IFCS neural network is a software processor that stores measured aircraft response information to dynamically alter flight control gains. In 2006, the neural network was engaged and allowed to learn in real time to dynamically alter the aircraft handling qualities characteristics in the presence of actual aerodynamic failure conditions injected into the aircraft through the flight control system. The use of neural network and similar adaptive technologies in the design of highly fault and damage tolerant flight control systems shows promise in making future aircraft far more survivable than current technology allows. This paper will present the results of the IFCS flight test program conducted at the NASA Dryden Flight Research Center in 2006, with emphasis on challenges encountered and lessons learned.
NASA-FAA helicopter Microwave Landing System curved path flight test

1984-01-01
An ongoing series of joint NASA/FAA helicopter Microwave Landing System (MLS) flight tests was conducted at Ames Research Center. This paper deals with tests done from the spring through the fall of 1983. This flight test investigated and developed solutions to the problem of manually flying curved-path and steep glide slope approaches into the terminal area using the MLS and flight director guidance. An MLS-equipped Bell UH-1H helicopter flown by NASA test pilots was used to develop approaches and procedures for flying these approaches. The approaches took the form of Straight-in, U-turn, and S-turn flightpaths with glide slopes of 6 deg, 9 deg, and 12 deg. These procedures were evaluated by 18 pilots from various elements of the helicopter community, flying a total of 221 hooded instrument approaches. Flying these curved path and steep glide slopes was found to be operationally acceptable with flight director guidance using the MLS.

Full Text Available In order to incorporate airworthiness requirements for flight characteristics into the entire development cycle of electronic flight control system (EFCS equipped civil aircraft, digital virtual flight testing and evaluation method based on handling qualities rating method (HQRM is proposed. First, according to HQRM, flight characteristics airworthiness requirements of civil aircraft in EFCS failure states are determined. On this basis, digital virtual flight testing model, comprising flight task digitized model, pilot controlling model, aircraft motion and atmospheric turbulence model, is used to simulate the realistic process of a pilot controlling an airplane to perform assigned flight tasks. According to the simulation results, flight characteristics airworthiness compliance of the airplane can be evaluated relying on the relevant regulations for handling qualities (HQ rating. Finally, this method is applied to a type of passenger airplane in a typical EFCS failure state, and preliminary conclusions concerning airworthiness compliance are derived quickly. The research results of this manuscript can provide important theoretical reference for EFCS design and actual airworthiness compliance verification of civil aircraft.
Flight test techniques for validating simulated nuclear electromagnetic pulse aircraft responses

An attempt has been made to determine the effects of nuclear EM pulses (NEMPs) on aircraft systems, using a highly instrumented NASA F-106B to document the simulated NEMP environment at the Kirtland Air Force Base's Vertically Polarized Dipole test facility. Several test positions were selected so that aircraft orientation relative to the test facility would be the same in flight as when on the stationary dielectric stand, in order to validate the dielectric stand's use in flight configuration simulations. Attention is given to the flight test portions of the documentation program.

Orbital debris in the millimeter size range can pose a hazard to current and planned spacecraft due to the high relative impact speeds in Earth orbit. Fortunately, orbital debris has a relatively short life at lower altitudes due to atmospheric effects; however, at higher altitudes orbital debris can survive much longer and has resulted in a band of high flux around 700 to 1,500 km above the surface of the Earth. While large orbital debris objects are tracked via ground based observation, little information can be gathered about small particles except by returned surfaces, which until the Orion Exploration Flight Test number one (EFT-1), has only been possible for lower altitudes (400 to 500 km). The EFT-1 crew module backshell, which used a porous, ceramic tile system with surface coatings, has been inspected post-flight for potential micrometeoroid and orbital debris (MMOD) damage. This paper describes the pre- and post-flight activities of inspection, identification and analysis of six candidate MMOD impact craters from the EFT-1 mission.

The enactment of the Eugenic Protection Act in Japan was followed by many changes. The population explosion was stemmed, the birth rate was halved, and while the marriage rate remained steady the divorce rate declined. The annual total of abortions increased until 1955 and then slowly declined. The highest incidence of abortions in families is in the 30 to 34 age group when there are four children in the family. As elsewhere abortion in advanced stages of pregnancy is associated with high morbidity and mortality. There is little consensus as to the number of criminal abortions. Reasons for criminal abortions can be found in the legal restrictions concerning abortion: Licensing of the abortionist, certification of hospitals, taxation of operations and the requirement that abortion be reported. Other factors are price competition and the patient's desire for secrecy. Contraception is relatively ineffective as a birth control method in Japan. Oral contraceptives are not yet government approved. In 1958 alone 1.1 per cent of married women were sterilized and the incidence of sterilization was increasing.
Perseus B Taxi Tests in Preparation for a New Series of Flight Tests
1998-01-01
The Perseus B remotely piloted aircraft taxis on the runway at Edwards Air Force Base, California, before a series of development flights at NASA's Dryden flight Research Center. The Perseus B is the latest of three versions of the Perseus design developed by Aurora Flight Sciences under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program. Perseus B is a remotely piloted aircraft developed as a design-performance testbed under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) project. Perseus is one of several flight vehicles involved in the ERAST project. A piston engine, propeller-powered aircraft, Perseus was designed and built by Aurora Flight Sciences Corporation, Manassas, Virginia. The objectives of Perseus B's ERAST flight tests have been to reach and maintain horizontal flight above altitudes of 60,000 feet and demonstrate the capability to fly missions lasting from 8 to 24 hours, depending on payload and altitude requirements. The Perseus B aircraft established an unofficial altitude record for a single-engine, propeller-driven, remotely piloted aircraft on June 27, 1998. It reached an altitude of 60,280 feet. In 1999, several modifications were made to the Perseus aircraft including engine, avionics, and flight-control-system improvements. These improvements were evaluated in a series of operational readiness and test missions at the Dryden Flight Research Center, Edwards, California. Perseus is a high-wing monoplane with a conventional tail design. Its narrow, straight, high-aspect-ratio wing is mounted atop the fuselage. The aircraft is pusher-designed with the propeller mounted in the rear. This design allows for interchangeable scientific-instrument payloads to be placed in the forward fuselage. The design also allows for unobstructed airflow to the sensors and other devices mounted in the payload compartment. The Perseus B that underwent test and development in 1999 was the third generation of the Perseus
Catholic attitudes toward abortion.
Smith, T W
1984-01-01
In the US attitudes toward abortion in the 1980s seem to have reached a more liberal plateau, much more favored than in the 1960s or earlier, but not longer moving in a liberal direction. Catholic attitudes basically have followed the same trend. Traditionally Catholic support has been slightly lower than Protestant, and both are less inclined to support abortion than Jews or the nonreligious. During the 1970s support among non-black Catholics averaged about 10 percentage points below non-black Protestants. Blacks tend to be anti-abortion and thereby lower support among Protestants as a whole. A comparison of Protestants and Catholics of both races shows fewer religious differences -- about 7 percentage points. There are some indications that this gap may be closing. In 1982, for the 1st time, support for abortions for social reasons, such as poverty, not wanting to marry, or not wanting more children, was as high among Catholics as among Protestants. 1 of the factors contributing to this narrowing gap has been the higher level of support for abortion among younger Catholics. Protestants show little variation on abortion attitudes, with those over age 65 being slightly less supportive. Among Catholics, support drops rapidly with age. This moderate and possibly vanishing difference between Catholics and Protestants contrasts sharply with the official positions of their respective churches. The Catholic Church takes an absolute moral position against abortion, while most Protestant churches take no doctrinaire position on abortion. Several, such as the Unitarians and Episcopalians, lean toward a pro-choice position as a matter of social policy, though fundamentalist sects take strong anti-abortion stances. Few Catholics agree with their church's absolutist anti-abortion position. The big split on abortion comes between what are sometimes termed the "hard" abortion reasons -- mother's health endangered, serious defect in fetus, rape, or incest. Support among Catholics

Unsafe abortion is a leading cause of death among young women aged 10-24 years in sub-Saharan Africa. Although having multiple induced abortions may exacerbate the risk for poor health outcomes, there has been minimal research on young women in this region who have multiple induced abortions. The objective of this study was therefore to assess the prevalence and correlates of reporting a previous induced abortion among young females aged 12-24 years seeking abortion-related care in Kenya. We used data on 1,378 young women aged 12-24 years who presented for abortion-related care in 246 health facilities in a nationwide survey conducted in 2012. Socio-demographic characteristics, reproductive and clinical histories, and physical examination assessment data were collected from women during a one-month data collection period using an abortion case capture form. Nine percent (n = 98) of young women reported a previous induced abortion prior to the index pregnancy for which they were receiving care. Statistically significant differences by previous history of induced abortion were observed for area of residence, religion and occupation at bivariate level. Urban dwellers and unemployed/other young women were more likely to report a previous induced abortion. A greater proportion of young women reporting a previous induced abortion stated that they were using a contraceptive method at the time of the index pregnancy (47 %) compared with those reporting no previous induced abortion (23 %). Not surprisingly, a greater proportion of young women reporting a previous induced abortion (82 %) reported their index pregnancy as unintended (not wanted at all or mistimed) compared with women reporting no previous induced abortion (64 %). Our study results show that about one in every ten young women seeking abortion-related care in Kenya reports a previous induced abortion. Comprehensive post-abortion care services targeting young women are needed. In particular, post-abortion
A comparative study of induced abortions before and after legalization of abortions.
Malhotra, S; Devi, P K
1979-06-01
Abortion was legalized in many states in India in April 1972. This study deals with 2 groups of patients admitted to P.G.I., Chadigarh, with problems of induced septic abortion. Group 1 consisted of 88 patients admitted during the 2 1/2 year period from 1 July 1969 to 31 December 1971, before the legalization of abortion. Group 2 consists of 133 patients admitted during the 2 1/2 year period from 1 July 1973 to 31 December 1975. 1 year after the new abortion law had been in force. Not only has there been an increase in the total number of patients, there has been an increase in the severity of infection. Evidently, the liberalization of the law has encouraged more patients to seek abortions and has encouraged more doctors, lacking proper qualifications, to perform them. The morbidity and mortality with induced septic abortion can only be reduced if enough public propaganda makes the people especially in rural areas conscious of the hazards of induced abortion by "dais" and unqualified personnel, simultaneously making them aware of the provision of law and facilities available at different centers. Meanwhile, the law against unskilled and untrained personnel should be rigorously enforced.
Hobi-like pestivirus in aborted bovine fetuses.

An outbreak of abortion affecting multiparous cows was associated with Hobi-like pestivirus infection. Viral RNA and antigens were detected in the tissues of two aborted fetuses. Molecular assays for other common abortogenic agents tested negative. At the genetic level, the Hobi-like pestivirus displayed the closest relatedness to Italian, Australian, and South American viruses, whereas it diverged from the prototype Thai isolate. These findings may have important implications for the pestivirus control/eradication programs in cattle herds.
Flight Tests of a Ministick Controller in an F/A-18 Airplane
Stoliker, Patrick C.; Carter, John
2003-01-01
In March of 1999, five pilots performed flight tests to evaluate the handling qualities of an F/A-18 research airplane equipped with a small-displacement center stick (ministick) controller that had been developed for the JAS 39 Gripen airplane (a fighter/attack/ reconnaissance airplane used by the Swedish air force). For these tests, the ministick was installed in the aft cockpit (see figure) and production support flight control computers (PSFCCs) were used as interfaces between the controller hardware and the standard F/A-18 flight-control laws. The primary objective of the flight tests was to assess any changes in handling qualities of the F/A-18 airplane attributable to the mechanical characteristics of the ministick. The secondary objective was to demonstrate the capability of the PSFCCs to support flight-test experiments.
Command and Data Handling Flight Software test framework: A Radiation Belt Storm Probes practice
Hill, T. A.; Reid, W. M.; Wortman, K. A.
During the Radiation Belt Storm Probes (RBSP) mission, a test framework was developed by the Embedded Applications Group in the Space Department at the Johns Hopkins Applied Physics Laboratory (APL). The test framework is implemented for verification of the Command and Data Handling (C& DH) Flight Software. The RBSP C& DH Flight Software consists of applications developed for use with Goddard Space Flight Center's core Flight Executive (cFE) architecture. The test framework's initial concept originated with tests developed for verification of the Autonomy rules that execute with the Autonomy Engine application of the RBSP C& DH Flight Software. The test framework was adopted and expanded for system and requirements verification of the RBSP C& DH Flight Software. During the evolution of the RBSP C& DH Flight Software test framework design, a set of script conventions and a script library were developed. The script conventions and library eased integration of system and requirements verification tests into a comprehensive automated test suite. The comprehensive test suite is currently being used to verify releases of the RBSP C& DH Flight Software. In addition to providing the details and benefits of the test framework, the discussion will include several lessons learned throughout the verification process of RBSP C& DH Flight Software. Our next mission, Solar Probe Plus (SPP), will use the cFE architecture for the C& DH Flight Software. SPP also plans to use the same ground system as RBSP. Many of the RBSP C& DH Flight Software applications are reusable on the SPP mission, therefore there is potential for test design and test framework reuse for system and requirements verification.
Post Flight Analysis Of SHEFEX I: Shock Tunnel Testing And Related CFD Analysis
Schramm, Jan Martinez; Barth, Tarik; Wagner, Alexander; Hannemann, Klaus
2011-05-01
The SHarp Edge Flight EXperiment (SHEFEX) program of the German Aerospace Center (DLR) is primarily focused on the investigation of the potential to utilise improved shapes for space vehicles by considering sharp edges and facetted surfaces. One goal is to set up a sky based test facility to gain knowledge of the physics of hypersonic flow, complemented by numerical analysis and ground based testing. Further, the series of SHEFEX flight experiments is an excellent test bed for new technological concepts and flight instrumentation, and it is a source of motivation for young scientist and engineers providing an excellent school for future space-program engineers and managers. After the successful first SHEFEX flight in October 2005, a second flight is scheduled for September 2011 and additional flights are planned for 2015 ff. With the SHEFEX-I flight and the subsequent numerical and experimental post flight analysis, DLR could for the first time close the loop between the three major disciplines of aerothermodynamic research namely CFD, ground based testing and flight.
[Induced abortion: a world perspective].
Henshaw, S K
1987-01-01
This article presents current estimates of the number, rate, and proportion of abortions for all countries which make such data available. 76% of the world's population lives in countries where induced abortion is legal at least for health reasons. Abortion is legal in almost all developed countries. Most developing countries have some laws against abortion, but it is permitted at least for health reasons in the countries of 67% of the developing world's population. The other 33%--over 1 billion persons--reside mainly in subSaharan Africa, Latin America, and the most orthodox Muslim countries. By the beginning of the 20th century, abortion had been made illegal in most of the world, with rules in Africa, Asia, and Latin America similar to those in Europe and North America. Abortion legislation began to change first in a few industrialized countries prior to World War II and in Japan in 1948. Socialist European countries made abortion legal in the first trimester in the 1950s, and most of the industrialized world followed suit in the 1960s and 1970s. The worldwide trend toward relaxed abortion restrictions continues today, with governments giving varying reasons for the changes. Nearly 33 million legal abortions are estimated to be performed annually in the world, with 14 million of them in China and 11 million in the USSR. The estimated total rises to 40-60 million when illegal abortions added. On a worldwide basis some 37-55 abortions are estimated to occur for each 1000 women aged 15-44 years. There are probably 24-32 abortions per 100 pregnancies. The USSR has the highest abortion rate among developed countries, 181/1000 women aged 15-44, followed by Rumania with 91/1000, many of them illegal. The large number of abortions in some countries is due to scarcity of modern contraception. Among developing countries, China apparently has the highest rate, 62/1000 women aged 15-44. Cuba's rate is 59/1000. It is very difficult to calculate abortion rates in countries
Artificial intelligence and expert systems in-flight software testing
Demasie, M. P.; Muratore, J. F.
1991-01-01
The authors discuss the introduction of advanced information systems technologies such as artificial intelligence, expert systems, and advanced human-computer interfaces directly into Space Shuttle software engineering. The reconfiguration automation project (RAP) was initiated to coordinate this move towards 1990s software technology. The idea behind RAP is to automate several phases of the flight software testing procedure and to introduce AI and ES into space shuttle flight software testing. In the first phase of RAP, conventional tools to automate regression testing have already been developed or acquired. There are currently three tools in use.

In the UK in 1988, 13.3% of abortions were performed at 13 weeks' gestation or later. Reasons for this delay, in addition to the diagnosis through amniocentesis of a fetal abnormality, include late recognition of pregnancy, a change of mind about completing the pregnancy, a failure of primary care physicians to entertain the diagnosis of pregnancy, travel or financial problems, and referral difficulties and scheduling delays. Women with little education and very young women are most likely to present for late abortions. From 13-16 weeks, dilatation and evacuation is the safest method of pregnancy termination. The procedure can be made easier through preparation of the cervix with a prostaglandin pessary or Foley catheter. After 16 weeks, an instillation method is recommended; prostaglandin administration can be intro- or extra-amniotic. Complication rates at 13-19 weeks are 14.5/1000 for vaginal methods of abortion and 7.2/1000 for prostaglandin methods. The risk of complications is 3 times higher for women who have 2nd-trimester abortions through the National Health Service. Although it is not realistic to expect that late abortions ever can be eliminated, improved sex education and contraceptive reliability as well as reforms in the National Health Service could reduce the number substantially. To reduce delay, it is suggested that the National Health Service set up satellite day care units and 1-2 central units in each region to deal quickly with midtrimester abortions. Delays would be further reduced by legislation to allow abortion on request in at least the 1st trimester of pregnancy.

Helicopter Acoustic Flight Test with Altitude Variation and Maneuvers
Watts, Michael E.; Greenwood, Eric; Sim, Ben; Stephenson, James; Smith, Charles D.
2016-01-01
A cooperative flight test campaign between NASA and the U.S. Army was performed from September 2014 to February 2015. The purposes of the testing were to: investigate the effects of altitude variation on noise generation, investigate the effects of gross weight variation on noise generation, establish the statistical variability in acoustic flight testing of helicopters, and characterize the effects of transient maneuvers on radiated noise for a medium-lift utility helicopter. This test was performed at three test sites (0, 4000, and 7000 feet above mean sea level) with two aircraft (AS350 SD1 and EH-60L) tested at each site. This report provides an overview of the test, documents the data acquired and describes the formats of the stored data.

Induced abortion contributes significantly to maternal mortality in developing countries yet women still seek repeat induced abortion in spite of availability of contraceptive services. The aim of this study is to determine the rate of abortion and contraceptive use among women seeking repeat induced abortion in Western Nigeria. A prospective cross-sectional study utilizing self-administered questionnaires was administered to women seeking abortion in private hospitals/clinics in four geopolitical areas of Ogun State, Western Nigeria, from January 1 to December 31 2012. Data were analyzed using SPSS 17.0. The age range for those seeking repeat induced abortion was 15 to 51 years while the median age was 25 years. Of 2934 women seeking an abortion, 23% reported having had one or more previous abortions. Of those who had had more than one abortion, the level of awareness of contraceptives was 91.7% while only 21.5% used a contraceptive at their first intercourse after the procedure; 78.5% of the pregnancies were associated with non-contraceptive use while 17.5% were associated with contraceptive failure. The major reason for non-contraceptive use was fear of side effects. The rate of women seeking repeat abortions is high in Nigeria. The rate of contraceptive use is low while contraceptive failure rate is high.
Trump's Abortion-Promoting Aid Policy.
Latham, Stephen R
2017-07-01
On the fourth day of his presidency, Donald Trump reinstated and greatly expanded the "Mexico City policy," which imposes antiabortion restrictions on U.S. foreign health aid. In general, the policy has prohibited U.S. funding of any family-planning groups that use even non-U.S. funds to perform abortions; prohibited aid recipients from lobbying (again, even with non-U.S. money) for liberalization of abortion laws; prohibited nongovernment organizations from creating educational materials on abortion as a family-planning method; and prohibited health workers from referring patients for legal abortions in any cases other than rape, incest, or to save the life of the mother. The policy's prohibition on giving aid to any organization that performs abortions is aimed at limiting alleged indirect funding of abortions. The argument is that if U.S. money is used to fund nonabortion programs of an abortion-providing NGO, then the NGO can simply shift the money thus saved into its abortion budget. Outside the context of abortion, we do not reason this way. And the policy's remaining three prohibitions are deeply troubling. © 2017 The Hastings Center.

Spontaneous abortion and unexpected death: a critical discussion of Marquis on abortion.
Coleman, Mary Clayton
2013-02-01
In his classic paper, 'Why abortion is immoral', Don Marquis argues that what makes killing an adult seriously immoral is that it deprives the victim of the valuable future he/she would have otherwise had. Moreover, Marquis contends, because abortion deprives a fetus of the very same thing, aborting a fetus is just as seriously wrong as killing an adult. Marquis' argument has received a great deal of critical attention in the two decades since its publication. Nonetheless, there is a potential challenge to it that seems to have gone unnoticed. A significant percentage of fetuses are lost to spontaneous abortion. Once we bring this fact to our attention, it becomes less clear whether Marquis can use his account of the wrongness of killing to show that abortion is the moral equivalent of murder. In this paper, I explore the relevance of the rate of spontaneous abortion to Marquis' classic anti-abortion argument. I introduce a case I call Unexpected Death in which someone is about to commit murder, but, just as the would-be murderer is about to strike, his would-be victim dies unexpectedly. I then ask: what does Marquis' account of killing imply about the moral status of what the would-be murderer was about to do? I consider four responses Marquis could give to this question, and I examine what implications these responses have for Marquis' strategy of using his account of the wrongness of killing an adult to show that abortion is in the same moral category.

Background Maternal mortality due to abortion complications stands among the three leading causes of maternal death in Botswana where there is a restrictive abortion law. This study aimed at assessing the patterns and determinants of post-abortion complications. Methods A retrospective institution based cross-sectional study was conducted at four hospitals from January to August 2014. Data were extracted from patients’ records with regards to their socio-demographic variables, abortion complications and length of hospital stay. Descriptive statistics and bivariate analysis were employed. Result A total of 619 patients’ records were reviewed with a mean (SD) age of 27.12 (5.97) years. The majority of abortions (95.5%) were reported to be spontaneous and 3.9% of the abortions were induced by the patient. Two thirds of the patients were admitted as their first visit to the hospitals and one third were referrals from other health facilities. Two thirds of the patients were admitted as a result of incomplete abortion followed by inevitable abortion (16.8%). Offensive vaginal discharge (17.9%), tender uterus (11.3%), septic shock (3.9%) and pelvic peritonitis (2.4%) were among the physical findings recorded on admission. Clinically detectable anaemia evidenced by pallor was found to be the leading major complication in 193 (31.2%) of the cases followed by hypovolemic and septic shock 65 (10.5%). There were a total of 9 abortion related deaths with a case fatality rate of 1.5%. Self-induced abortion and delayed uterine evacuation of more than six hours were found to have significant association with post-abortion complications (p-values of 0.018 and 0.035 respectively). Conclusion Abortion related complications and deaths are high in our setting where abortion is illegal. Mechanisms need to be devised in the health facilities to evacuate the uterus in good time whenever it is indicated and to be equipped to handle the fatal complications. There is an indication for

[Psychological aspects of induced abortion].
Mouniq, C; Moron, P
1982-06-01
Results are presented of a literature review to identify social and psychological aspects of abortion. The literature does not provide a true profile of women requesting abortions, but some characteristics emerge. Reasons for requesting abortion include economic problems, difficult previous pregnancies, general medical contraindications to pregnancy, marital conflicts, feelings of loneliness, professional aspirations, problems with existing children, and feelings of insecurity about the future. However, the same feelings are found among women carrying their pregnancies to term. Unplanned pregnancies are more common during periods of depression. Most authors have found about 1/2 of women seeking abortions to be single and about 1/2 to be under 25 years old. Religion does not appear to be a determining factor. 1 study of psychological factors in abortion seekers found that a large number of single women seeking abortion had suffered traumatic experiences in childhood and were seeking security in inappropriate amorous relationships. Helene Deutsch stressed the destructive impulses latent in all pregnancies. Others have cited the ambivalence of the desire for pregnancy and feelings of loss after abortion. Studies published after legalization of abortion in the US and France however have stressed the nearly total absence of moderate or severe psychiatric symptoms after abortion. Responses immediately after the abortion may include feelings of relief, guilt, indifference, or ambivalence. Secondary affects appear minor to most authors. Psychological effects do not appear to be influenced by age, marital status, parity, intelligence, occupation, existence of a later pregnancy, or concommitant sterilization. "Premorbidity" and coercion by spouse or family were most closely associated with psychological symptoms. Numerous authors have found about twice as many negative reactions among women undergoing abortion for medical reasons. Most patients undergoing abortions for

Background Rural induced abortion service has declined in Canada. Factors influencing abortion provision by rural physicians are unknown. This study assessed distribution, practice, and experiences among rural compared to urban abortion providers in the Canadian province of British Columbia (BC). Methods We used mixed methods to assess physicians on the BC registry of abortion providers. In 2011 we distributed a previously-published questionnaire and conducted semi-structured interviews. Results Surveys were returned by 39/46 (85%) of BC abortion providers. Half were family physicians, within both rural and urban cohorts. One-quarter (17/67) of rural hospitals offer abortion service. Medical abortions comprised 14.7% of total reported abortions. The three largest urban areas reported 90% of all abortions, although only 57% of reproductive age women reside in the associated health authority regions. Each rural physician provided on average 76 (SD 52) abortions annually, including 35 (SD 30) medical abortions. Rural physicians provided surgical abortions in operating rooms, often using general anaesthesia, while urban physicians provided the same services primarily in ambulatory settings using local anaesthesia. Rural providers reported health system barriers, particularly relating to operating room logistics. Urban providers reported occasional anonymous harassment and violence. Conclusions Medical abortions represented 15% of all BC abortions, a larger proportion than previously reported (under 4%) for Canada. Rural physicians describe addressable barriers to service provision that may explain the declining accessibility of rural abortion services. Moving rural surgical abortions out of operating rooms and into local ambulatory care settings has the potential to improve care and costs, while reducing logistical challenges facing rural physicians.

Automated Testing Experience of the Linear Aerospike SR-71 Experiment (LASRE) Controller
Larson, Richard R.
1999-01-01
System controllers must be fail-safe, low cost, flexible to software changes, able to output health and status words, and permit rapid retest qualification. The system controller designed and tested for the aerospike engine program was an attempt to meet these requirements. This paper describes (1) the aerospike controller design, (2) the automated simulation testing techniques, and (3) the real time monitoring data visualization structure. Controller cost was minimized by design of a single-string system that used an off-the-shelf 486 central processing unit (CPU). A linked-list architecture, with states (nodes) defined in a user-friendly state table, accomplished software changes to the controller. Proven to be fail-safe, this system reported the abort cause and automatically reverted to a safe condition for any first failure. A real time simulation and test system automated the software checkout and retest requirements. A program requirement to decode all abort causes in real time during all ground and flight tests assured the safety of flight decisions and the proper execution of mission rules. The design also included health and status words, and provided a real time analysis interpretation for all health and status data.

A female Catholic theologian imagines a just society that does not judge women who decide to undergo an abortion. The Church, practitioners, and the courts must trust that women do make person-enhancing choices about the quality of life. In the last 15 years most progress in securing a woman's right to abortion has been limited to white, well-educated, and middle or upper middle class women. A just society would consider reproductive options a human right. Abortion providers are examples of a move to a just society; they are committed to women's well-being. There are some facts that make one pessimistic about achieving abortion in a just society. The US Supreme Court plans to review important decisions establishing abortion as a civil right. Further, some men insist on suing women who want to make their own reproductive decisions--an anti-choice tactic to wear away women's right to reproductive choice. Bombings of abortion clinics and harassment campaigns by anti-choice groups are common. These behaviors strain pro-choice proponents emotionally, psychically, and spiritually. Their tactics often lead to theologians practicing self-censorship because they fear backlash. Abortion providers also do this. Further, the reaction to AIDS is that sex is bad. Anti-abortion groups use AIDS to further their campaigns, claiming that AIDS is a punishment for sex. Strategies working towards abortion in a just society should be education and persuasion of policymakers and citizens about women's right to choose, since they are the ones most affected by abortion. Moreover, only women can secure their rights to abortion. In a just society, every health maintenance organization, insurance company, and group practice would consider abortion a normal service. A just society provides for the survival needs of the most marginalized.
Aerodynamic Reconstruction Applied to Parachute Test Vehicle Flight Data Analysis
Cassady, Leonard D.; Ray, Eric S.; Truong, Tuan H.
2013-01-01
The aerodynamics, both static and dynamic, of a test vehicle are critical to determining the performance of the parachute cluster in a drop test and for conducting a successful test. The Capsule Parachute Assembly System (CPAS) project is conducting tests of NASA's Orion Multi-Purpose Crew Vehicle (MPCV) parachutes at the Army Yuma Proving Ground utilizing the Parachute Test Vehicle (PTV). The PTV shape is based on the MPCV, but the height has been reduced in order to fit within the C-17 aircraft for extraction. Therefore, the aerodynamics of the PTV are similar, but not the same as, the MPCV. A small series of wind tunnel tests and computational fluid dynamics cases were run to modify the MPCV aerodynamic database for the PTV, but aerodynamic reconstruction of the flights has proven an effective source for further improvements to the database. The acceleration and rotational rates measured during free flight, before parachute inflation but during deployment, were used to con rm vehicle static aerodynamics. A multibody simulation is utilized to reconstruct the parachute portions of the flight. Aerodynamic or parachute parameters are adjusted in the simulation until the prediction reasonably matches the flight trajectory. Knowledge of the static aerodynamics is critical in the CPAS project because the parachute riser load measurements are scaled based on forebody drag. PTV dynamic damping is critical because the vehicle has no reaction control system to maintain attitude - the vehicle dynamics must be understood and modeled correctly before flight. It will be shown here that aerodynamic reconstruction has successfully contributed to the CPAS project.

1993-10-01
The topic of this article is the use of unsafe abortion for unwanted pregnancies among adolescents. The significance of unsafe abortion is identified as a high risk of serious health problems, such as infection, hemorrhage, infertility, and mortality, and as a strain on emergency room services. The World Health Organization estimates that at least 33% of all women seeking hospital care for abortion complications are aged under 20 years. 50 million abortions are estimated to be induced annually, of which 33% are illegal and almost 50% are performed outside the health care system. Complications are identified as occurring due to the procedure itself (perforation of the uterus, cervical lacerations, or hemorrhage) and due to incomplete abortion or introduction of bacteria into the uterus. Long-term complications include an increased risk of ectopic pregnancy, chronic pelvic infection, and infertility. Mortality from unsafe abortion is estimated at 1000/100,000 procedures. Safe abortion mortality is estimated at 0.6/100,000. When infertility results, some cultures ascribe an outcast status or marriages are prevented or prostitution is assured. The risk of complications is considered higher for adolescents. Adolescents tend to delay seeking an abortion, lack knowledge on where to go for a safe procedure, and delay seeking help for complications. Peer advice may be limited or inadequate knowledge. Five studies are cited that illustrate the impact of unsafe abortion on individuals and health care systems. Abortions may be desired due to fear of parental disapproval of the pregnancy, abandonment by the father, financial and emotional responsibilities of child rearing, expulsion from school, or inability to marry if the child is out of wedlock. Medical, legal, and social barriers may prevent women and girls from obtaining safe abortion. Parental permission is sometimes a requirement for safe abortion. Fears of judgmental or callous health personnel may be barriers to
Patterns of online abortion among teenagers

An on-going debate of whether or not to legalize abortion has not stopped the number of abortion cases decreases. New practices of abortion such as online abortion has been a growing trend among teenagers. This study aims to determine how teenagers use social media such as Facebook, YouTube and Wikipedia for the practice of abortion. This study adopted online research methods (ORMs), a qualitative approach 2.0 by hacking analytical perspective developed. This study establishes online teen abortion as a research subject. This study finds patterns of online abortions among teenagers covering characteristics of teenagers as perpetrators, styles of communication, and their implication toward policy, particularly Electronic Transaction Information (ETI) regulation. Implications for online abortion behavior among teenagers through social media. The potential abortion client especially girls find practical, fast, effective, and efficient solutions that keep their secret. One of prevention patterns that has been done by some people who care about humanity and anti-abortion in the online world is posting a anti-abortion text, video or picture, anti-sex-free (anti -free intercourse before marriage) in an interesting, educative, and friendly ways.

Full Text Available This essay explores how gender studies in academe, including in religious studies, might remain relevant to ongoing feminist political engagement. I explore some specific dynamics of this challenge, using as my test case the issue of abortion in the U.S. After discussing how three formative feminist principles (women’s experience as feminism’s starting point, the personal is political, and identity politics have shaped approaches to the abortion issue for feminist scholars in religion, I argue that ongoing critique, new theoretical perspectives, and attentiveness to subaltern voices are necessary for these foundational feminist principles to keep pace with fast-changing and complex societal dynamics relevant to women’s struggles for reproductive health and justice. The essay concludes by proposing ‘natality’ as a helpful concept for future feminist theological and ethical thinking on the subject.
Steinberg, Julia R
2011-01-01
Some abortion policies in the U.S. are based on the notion that abortion harms women's mental health. The American Psychological Association (APA) Task Force on Abortion and Mental Health concluded that first-trimester abortions do not harm women's mental health. However, the APA task force does not make conclusions regarding later abortions (second trimester or beyond) and mental health. This paper critically evaluates studies on later abortion and mental health in order to inform both policy and practice. Using guidelines outlined by Steinberg and Russo (2009), post 1989 quantitative studies on later abortion and mental health were evaluated on the following qualities: 1) composition of comparison groups, 2) how prior mental health was assessed, and 3) whether common risk factors were controlled for in analyses if a significant relationship between abortion and mental health was found. Studies were evaluated with respect to the claim that later abortions harm women's mental health. Eleven quantitative studies that compared the mental health of women having later abortions (for reasons of fetal anomaly) with other groups were evaluated. Findings differed depending on the comparison group. No studies considered the role of prepregnancy mental health, and one study considered whether factors common among women having later abortions and mental health problems drove the association between later abortion and mental health. Policies based on the notion that later abortions (because of fetal anomaly) harm women's mental health are unwarranted. Because research suggests that most women who have later abortions do so for reasons other than fetal anomaly, future investigations should examine women's psychological experiences around later abortions.

Constructing abortion as a social problem: "Sex selection" and the British abortion debate.
Lee, Ellie
2017-02-01
Between February 2012 and March 2015, the claim that sex selection abortion was taking place in Britain and that action needed to be taken to stop it dominated debate in Britain about abortion. Situating an analysis in sociological and social psychological approaches to the construction of social problems, particularly those considering "feminised" re-framings of anti-abortion arguments, this paper presents an account of this debate. Based on analysis of media coverage, Parliamentary debate and official documents, we focus on claims about grounds (evidence) made to sustain the case that sex selection abortion is a British social problem and highlight how abortion was problematised in new ways. Perhaps most notable, we argue, was the level of largely unchallenged vilification of abortion doctors and providers, on the grounds that they are both law violators and participants in acts of discrimination and violence against women, especially those of Asian heritage. We draw attention to the role of claims made by feminists in the media and in Parliament about "gendercide" as part of this process and argue that those supportive of access to abortion need to critically assess both this aspect of the events and also consider arguments about the problems of "medical power" in the light of what took place.

Background Abortion was legalized in Nepal in 2002, following advocacy efforts highlighting high maternal mortality from unsafe abortion. We sought to assess whether legalization led to reductions in the most serious maternal health consequences of unsafe abortion. Methods We conducted retrospective medical chart review of all gynecological cases presenting at four large public referral hospitals in Nepal. For the years 2001–2010, all cases of spontaneous and induced abortion complications were identified, abstracted, and coded to classify cases of serious infection, injury, and systemic complications. We used segmented Poisson and ordinary logistic regression to test for trend and risks of serious complications for three time periods: before implementation (2001–2003), early implementation (2004–2006), and later implementation (2007–2010). Results 23,493 cases of abortion complications were identified. A significant downward trend in the proportion of serious infection, injury, and systemic complications was observed for the later implementation period, along with a decline in the risk of serious complications (OR 0.7, 95% CI 0.64, 0.85). Reductions in sepsis occurred sooner, during early implementation (OR 0.6, 95% CI 0.47, 0.75). Conclusion Over the study period, health care use and the population of reproductive aged women increased. Total fertility also declined by nearly half, despite relatively low contraceptive prevalence. Greater numbers of women likely obtained abortions and sought hospital care for complications following legalization, yet we observed a significant decline in the rate of serious abortion morbidity. The liberalization of abortion policy in Nepal has benefited women’s health, and likely contributes to falling maternal mortality in the country. The steepest decline was observed after expansion of the safe abortion program to include midlevel providers, second trimester training, and medication abortion, highlighting the importance
Unconstitutionality of abortion laws affirmed.
1979-08-01
A federal appeals court has affirmed lower court rulings that substantial portions of the Illinois' 1975 Abortion Act and 1977 Abortion Parental Consent Act are unconstitutional. The 7th Court adopted an April 12, 1978 district court opinion that invalidated several sections of the Illinois 1975 abortion statute, including parental and spousal consent requirements and provisions requiring that a woman be informed of the "physical competency" of the fetus at the time the abortion was to be performed. The appeals court specifically addressed the statute's provision making a liveborn fetus resulting from an abortion a ward of the state, unless the abortion was performed to save the woman's life. Regarding the 1977 Parental Consent Act, the 7th Circuit reaffirmed its August 1978 ruling that it is unconstitutional to require an unmarried minor to have the consent of both parents or, if they refused consent, a circuit court judge before undergoing an abortion. The appeals court also agreed with the lower court's November 2nd ruling that the Act's requirement of a 48-hour delay between the time the minor gives her consent and the performance of an abortion violated the equal protection clause of the 14th amendment.
An epidemiologic study of late-term abortions in dairy cattle in Denmark, July 2000 August 2003

Abortion Stigma: A Systematic Review.
Hanschmidt, Franz; Linde, Katja; Hilbert, Anja; Riedel-Heller, Steffi G; Kersting, Anette
2016-12-01
Although stigma has been identified as a potential risk factor for the well-being of women who have had abortions, little attention has been paid to the study of abortion-related stigma. A systematic search of the databases Medline, PsycArticles, PsycInfo, PubMed and Web of Science was conducted; the search terms were "(abortion OR pregnancy termination) AND stigma * ." Articles were eligible for inclusion if the main research question addressed experiences of individuals subjected to abortion stigma, public attitudes that stigmatize women who have had abortions or interventions aimed at managing abortion stigma. To provide a comprehensive overview of this issue, any study published by February 2015 was considered. The search was restricted to English- and German-language studies. Seven quantitative and seven qualitative studies were eligible for inclusion. All but two dated from 2009 or later; the earliest was from 1984. Studies were based mainly on U.S. samples; some included participants from Ghana, Great Britain, Mexico, Nigeria, Pakistan, Peru and Zambia. The majority of studies showed that women who have had abortions experience fear of social judgment, self-judgment and a need for secrecy. Secrecy was associated with increased psychological distress and social isolation. Some studies found stigmatizing attitudes in the public. Stigma appeared to be salient in abortion providers' lives. Evidence of interventions to reduce abortion stigma was scarce. Most studies had limitations regarding generalizability and validity. More research, using validated measures, is needed to enhance understanding of abortion stigma and thereby reduce its impact on affected individuals. Copyright © 2016 by the Guttmacher Institute.

Tackling unsafe abortion in Mauritius.
Nyong'o, D; Oodit, G
1996-01-01
Despite a contraceptive prevalence rate of 75% Mauritius has a high incidence of unsafe abortions because of unprotected intercourse experienced by many young women in a rapidly industrializing environment. The Mauritius Family Planning Association (MFPA) tackled the issue of unsafe abortion in 1993. Abortion is illegal in the country, and the Catholic Church also strongly opposes modern family planning methods, thus the use of withdrawal and/or calendar methods have been increasing. The MFPA organized an advocacy symposium in 1993 on unsafe abortion with the result of revealing the pressure the Church was exerting relative to abortion and contraceptives. The advocacy campaign of the MFPA consists of having abortion legalized on health grounds and improving family planning services, especially for young unmarried women and men. The full support of the media was secured on the abortion issue: articles appeared, meetings were attended by the press, and public relations support was also received from them. The MFPA worked closely with parliamentarians. A motion was tabled in 1994 in the National Assembly which called for legalization of abortion on health grounds, but the Church squelched its debate. In March 1994 MFPA hosted the IPPF African Regional Conference on Unsafe Abortion in Mauritius with the participation of over 100 representatives from 20 countries, and subsequently a second motion was tabled without parliamentary debate. The deliberations were covered by the media and the Ministry of Women's Rights recognized abortion as an urgent issue as outlined in a white paper prepared for the Fourth World Conference on Women held in Beijing in 1995. The campaign changed the policy climate favorably making the public more conscious of unsafe abortion. The Ministry of Health decided to collect more data and the newly elected government seems to be more open about this issue.
The incidence of abortion and unintended pregnancy in India, 2015

1000 women aged 15–49 years. 3·4 million abortions (22%) were obtained in health facilities, 11·5 million (73%) abortions were medication abortions done outside of health facilities, and 0·8 million (5%) abortions were done outside of health facilities using methods other than medication abortion. Overall, 12·7 million (81%) abortions were medication abortions, 2·2 million (14%) abortions were surgical, and 0·8 million (5%) abortions were done through other methods that were probably unsafe. We estimated 48·1 million pregnancies, a rate of 144·7 pregnancies per 1000 women aged 15–49 years, and a rate of 70·1 unintended pregnancies per 1000 women aged 15–49 years. Abortions accounted for one third of all pregnancies, and nearly half of pregnancies were unintended. Interpretation Health facilities can have a greater role in abortion service provision and provide quality care, including post-abortion contraception. Interventions are needed to expand access to abortion services through better equipping existing facilities, ensuring adequate and continuous supplies of medication abortion drugs, and by increasing the number of trained providers. In view of how many women rely on self-administration of medication abortion drugs, interventions are needed to provide women with accurate information on these drugs and follow-up care when needed. Research is needed to test interventions that improve knowledge and practice in providing medication abortion, and the Indian Government at the national and state level needs to prioritise improving policies and practice to increase access to comprehensive abortion care and quality contraceptive services that prevent unintended pregnancy.

Modelling of XCO2 Surfaces Based on Flight Tests of TanSat Instruments
Directory of Open Access Journals (Sweden)
Li Li Zhang
2016-11-01
Full Text Available The TanSat carbon satellite is to be launched at the end of 2016. In order to verify the performance of its instruments, a flight test of TanSat instruments was conducted in Jilin Province in September, 2015. The flight test area covered a total area of about 11,000 km2 and the underlying surface cover included several lakes, forest land, grassland, wetland, farmland, a thermal power plant and numerous cities and villages. We modeled the column-average dry-air mole fraction of atmospheric carbon dioxide (XCO2 surface based on flight test data which measured the near- and short-wave infrared (NIR reflected solar radiation in the absorption bands at around 760 and 1610 nm. However, it is difficult to directly analyze the spatial distribution of XCO2 in the flight area using the limited flight test data and the approximate surface of XCO2, which was obtained by regression modeling, which is not very accurate either. We therefore used the high accuracy surface modeling (HASM platform to fill the gaps where there is no information on XCO2 in the flight test area, which takes the approximate surface of XCO2 as its driving field and the XCO2 observations retrieved from the flight test as its optimum control constraints. High accuracy surfaces of XCO2 were constructed with HASM based on the flight’s observations. The results showed that the mean XCO2 in the flight test area is about 400 ppm and that XCO2 over urban areas is much higher than in other places. Compared with OCO-2’s XCO2, the mean difference is 0.7 ppm and the standard deviation is 0.95 ppm. Therefore, the modelling of the XCO2 surface based on the flight test of the TanSat instruments fell within an expected and acceptable range.
Psychiatric sequelae of induced abortion.
Gibbons, M
1984-03-01
An attempt is made to identify and document the problems of comparative evaluation of the more recent studies of psychiatric morbidity after abortion and to determine the current consensus so that when the results of the joint RCGP/RCOG study of the sequelae of induced abortion become available they can be viewed in a more informed context. The legalization of abortion has provided more opportunities for studies of subsequent morbidity. New laws have contributed to the changing attitudes of society, and the increasing acceptability of the operation has probably influenced the occurrence of psychiatric sequelae. The complexity of measuring psychiatric sequelae is evident from the many terms used to describe symptomatology and behavioral patterns and from the number of assessment techniques involved. Numerous techniques have been used to quantify psychiatric sequelae. Several authors conclude that few psychiatric problems follow an induced abortion, but many studies were deficient in methodology, material, or length of follow-up. A British study in 1975 reported a favorable outcome for a "representative sample" of 50 National Health Service patients: 68% of these patients had an absence of or only mild feelings of guilt, loss, or self reproach and considered abortion as the best solution to their problem. The 32% who had an adverse outcome reported moderate to severe feelings of guilt, regret, loss, and self reproach, and there was evidence of mental illness. In most of these cases the adverse outcome was related to the patient's environment since the abortion. A follow-up study of 126 women, which compared the overall reaction to therapeutic abortion between women with a history of previous mild psychiatric illness and those without reported that a significantly different emotional reaction could not be demonstrated between the 2 groups. In a survey among women seeking an abortion 271 who were referred for a psychiatric opinion regarding terminations of pregnancy
Induced abortion and contraception in Italy.
Spinelli, A; Grandolfo, M E
1991-09-01
This article discusses the legal and epidemiologic status of abortion in Italy, and its relationship to fertility and contraception. Enacted in May 1978, Italy's abortion law allows the operation to be performed during the 1st 90 days of gestation for a broad range of health, social, and psychological reasons. Women under 18 must receive written permission from a parent, guardian, or judge in order to undergo an abortion. The operation is free of charge. Health workers who object to abortion because of religious or moral reasons are exempt from participating. Regional differences exist concerning the availability of abortion, easy to procure in some places and difficult to obtain in others. After an initial increase following legalization, the abortion rate was 13.5/1000 women aged 15-44 and the abortion ratio was 309/1000 live births -- an intermediate rate and ratio compared to other countries. By the time the Abortion Act of 1978 was adopted, Italy already had one of the lowest fertility levels in Europe. Thus, the legalization of abortion has had no impact on fertility trends. Contrary to initial fears that the legalization of abortion would make abortion a method of family planning, 80% of the women who sought an abortion in 1983-88 were using birth control at the time (withdrawal being the most common method used by this group). In fact, most women who undergo abortions are married, between the ages of 25-34, and with at least one child. Evidence indicates widespread ignorance concerning reproduction. In a 1989 survey, only 65% of women could identify the fertile period of the menstrual cycle. Italy has no sex education in schools or national family planning programs. Compared to most of Europe, Italy still has low levels of reliable contraceptive usage. This points to the need to guarantee the availability of abortion.
Abortion Incidence and Unintended Pregnancy in Nepal.
Puri, Mahesh; Singh, Susheela; Sundaram, Aparna; Hussain, Rubina; Tamang, Anand; Crowell, Marjorie
2016-12-01
Although abortion has been legal under broad criteria in Nepal since 2002, a significant proportion of women continue to obtain illegal, unsafe abortions, and no national estimates exist of the incidence of safe and unsafe abortions. Data were collected in 2014 from a nationally representative sample of 386 facilities that provide legal abortions or postabortion care and a survey of 134 health professionals knowledgeable about abortion service provision. Facility caseloads and indirect estimation techniques were used to calculate the national and regional incidence of legal and illegal abortion. National and regional levels of abortion complications and unintended pregnancy were also estimated. In 2014, women in Nepal had 323,100 abortions, of which 137,000 were legal, and 63,200 women were treated for abortion complications. The abortion rate was 42 per 1,000 women aged 15-49, and the abortion ratio was 56 per 100 live births. The abortion rate in the Central region (59 per 1,000) was substantially higher than the national average. Overall, 50% of pregnancies were unintended, and the unintended pregnancy rate was 68 per 1,000 women of reproductive age. Despite legalization of abortion and expansion of services in Nepal, unsafe abortion is still common and exacts a heavy toll on women. Programs and policies to reduce rates of unintended pregnancy and unsafe abortion, increase access to high-quality contraceptive care and expand safe abortion services are warranted.
Software Considerations for Subscale Flight Testing of Experimental Control Laws
Murch, Austin M.; Cox, David E.; Cunningham, Kevin
2009-01-01
The NASA AirSTAR system has been designed to address the challenges associated with safe and efficient subscale flight testing of research control laws in adverse flight conditions. In this paper, software elements of this system are described, with an emphasis on components which allow for rapid prototyping and deployment of aircraft control laws. Through model-based design and automatic coding a common code-base is used for desktop analysis, piloted simulation and real-time flight control. The flight control system provides the ability to rapidly integrate and test multiple research control laws and to emulate component or sensor failures. Integrated integrity monitoring systems provide aircraft structural load protection, isolate the system from control algorithm failures, and monitor the health of telemetry streams. Finally, issues associated with software configuration management and code modularity are briefly discussed.

In Victoria, Australia, abortion was decriminalised in October 2008, bringing the law in line with clinical practice and community attitudes. We describe how experts in abortion service provision perceived the intent and subsequent impact of the 2008 Victorian abortion law reform. Experts in abortion provision in Victoria were recruited for a qualitative semi-structured interview about the 2008 law reform and its perceived impact, until saturation was reached. Nineteen experts from a range of health care settings and geographic locations were interviewed in 2014/2015. Thematic analysis was conducted to summarise participants' views. Abortion law reform, while a positive event, was perceived to have changed little about the provision of abortion. The views of participants can be categorised into: (1) goals that law reform was intended to address and that have been achieved; (2) intent or hopes of law reform that have not been achieved; (3) unintended consequences; (4) coincidences; and (5) unfinished business. All agreed that law reform had repositioned abortion as a health rather than legal issue, had shifted the power in decision making from doctors to women, and had increased clarity and safety for doctors. However, all described outstanding concerns; limited public provision of surgical abortion; reduced access to abortion after 20 weeks; ongoing stigma; lack of a state-wide strategy for equitable abortion provision; and an unsustainable workforce. Law reform, while positive, has failed to address a number of significant issues in abortion service provision, and may have even resulted in a 'lull' in action.

Subscale Flight Testing for Aircraft Loss of Control: Accomplishments and Future Directions
Cox, David E.; Cunningham, Kevin; Jordan, Thomas L.
2012-01-01
Subscale flight-testing provides a means to validate both dynamic models and mitigation technologies in the high-risk flight conditions associated with aircraft loss of control. The Airborne Subscale Transport Aircraft Research (AirSTAR) facility was designed to be a flexible and efficient research facility to address this type of flight-testing. Over the last several years (2009-2011) it has been used to perform 58 research flights with an unmanned, remotely-piloted, dynamically-scaled airplane. This paper will present an overview of the facility and its architecture and summarize the experimental data collected. All flights to date have been conducted within visual range of a safety observer. Current plans for the facility include expanding the test volume to altitudes and distances well beyond visual range. The architecture and instrumentation changes associated with this upgrade will also be presented.

The need is examined for orbital flight tests of gyroscope, dewar, and other components, in order to reduce the technical and financial risk in performing the relativity experiment. A program is described that would generate engineering data to permit prediction of final performance. Two flight tests are recommended. The first flight would test a dewar smaller than that required for the final flight, but of size and form sufficient to allow extrapolation to the final design. The second flight would use the same dewar design to carry a set of three gyroscopes, which would be evaluated for spinup and drift characteristics for a period of a month or more. A proportional gas control system using boiloff helium gas from the dewar, and having the ability to prevent sloshing of liquid helium, would also be tested.
Abortion in Croatia and Slovenia.
1992-01-01
In Slovenia abortion will continue to be available during the first 10 weeks of pregnancy as it has been since 1978. The Slovenian Constitutional Court passed this decision in December, 1991 calling the right to abortion a basic human right. T he ruling was a setback both for the government's conservative parties and the Catholic church. In Croatia, where the Catholic church is campaigning against abortion, the situation is quite different. Zagreb is full of stickers and posters with anti-abortion messages branding abortion murder and spreading inaccurate information in announcements. In 1990, there were 56,000 abortions. For every child that was born, one was aborted. The largest Croatian newspaper publicizes the Catholic view. They want pro-choice women of the volunteer group Tresnjevka to stop their struggle. The church and conservative women's groups press for inclusion of abortion in the Constitution. They are very powerful, and the fear is that might soon succeed in restricting or outlawing abortion. Tresnjevka is making efforts to organize a coordination and information center for women in Zagreb where there are 350,000 women and children refugees. Informative brochures are printed on natural healing methods in gynecology, as drugs are very scarce, and addresses for gynecological emergency care are also provided. Abortion has been legally available on demand during the 1st 10 weeks of pregnancy since 1978. Fore year Tresnjevka has worked for women, trying to raise funds from personal donations and from the government for their activities. Funds from foreign countries have never been received. At present many of the group's activities are on hold because of lack of funds, nevertheless the determination to continue fighting is alive.
Psychosocial aspects of induced abortion.
Stotland, N L
1997-09-01
US anti-abortion groups have used misinformation on the long-term psychological impact of induced abortion to advance their position. This article reviews the available research evidence on the definition, history, cultural context, and emotional and psychiatric sequelae of induced abortion. Notable has been a confusion of normative, transient reactions to unintended pregnancy and abortion (e.g., guilt, depression, anxiety) with serious mental disorders. Studies of the psychiatric aspects of abortion have been limited by methodological problems such as the impossibility of randomly assigning women to study and control groups, resistance to follow-up, and confounding variables. Among the factors that may impact on an unintended pregnancy and the decision to abort are ongoing or past psychiatric illness, poverty, social chaos, youth and immaturity, abandonment issues, ongoing domestic responsibilities, rape and incest, domestic violence, religion, and contraceptive failure. Among the risk factors for postabortion psychosocial difficulties are previous or concurrent psychiatric illness, coercion to abort, genetic or medical indications, lack of social supports, ambivalence, and increasing length of gestation. Overall, the literature indicates that serious psychiatric illness is at least 8 times more common among postpartum than among postabortion women. Abortion center staff should acknowledge that the termination of a pregnancy may be experienced as a loss even when it is a voluntary choice. Referrals should be offered to women who show great emotional distress, have had several previous abortions, or request psychiatric consultation.
Legalized abortion: a public health success story.
Kelly, M
1999-06-01
60% of more than 2000 women surveyed by the Picker Institute who underwent induced abortion procedures rated the quality of their care as excellent. Another third reported their care as being either very good or good. The survey also found that the quality of abortion care is comparable to other outpatient surgery. However, the high quality of care women receive from abortion providers is lost in the hostile anti-abortion climate created by threatening protesters outside of clinics and the murder of 7 clinic workers and physicians who performed abortions. Abortion opponents fail to acknowledge that legal abortion is a medical procedure which protects women's health and saves their lives. Before abortion was legalized in the US, countless women were either rendered unable to reproduce or died from abortion-related complications. Efforts to outlaw abortion persist despite it being widely recognized by medical experts as one of the most safe medical procedures currently performed in the US. When state legislatures target abortion providers with unduly strict regulations, abortion becomes prohibitively expensive and difficult to obtain.
Husbands' involvement in abortion in Vietnam.

This study analyzes the involvement of men in abortion in Vietnam, where induced abortion is legal and abortion rates are among the highest in the world. Twenty men were interviewed in 1996 about the role they played in their wives' abortions and about their feelings and ethical views concerning the procedure. The results showed that both husbands and wives considered the husband to be the main decisionmaker regarding family size, which included the decision to have an abortion, but that, in fact, some women had undergone an abortion without consulting their husbands in advance. Parents and in-laws were usually not consulted; the couples thought they might object to the decision on moral grounds. Respondents' ethical perspectives on abortion are discussed. When faced with an unwanted pregnancy, the husbands adopted an ethics of care and responsibility toward family and children, although some felt that abortion was immoral. The study highlights the importance of understanding husbands' perspectives on their responsibilities and rights in reproductive decisionmaking and their ethical and other concerns related to abortion.
Crime, Teenage Abortion, and Unwantedness
Shoesmith, Gary L.
2015-01-01
This article disaggregates Donohue and Levitt’s (DL’s) national panel-data models to the state level and shows that high concentrations of teenage abortions in a handful of states drive all of DL’s results in their 2001, 2004, and 2008 articles on crime and abortion. These findings agree with previous research showing teenage motherhood is a major maternal crime factor, whereas unwanted pregnancy is an insignificant factor. Teenage abortions accounted for more than 30% of U.S. abortions in the 1970s, but only 16% to 18% since 2001, which suggests DL’s panel-data models of crime/arrests and abortion were outdated when published. The results point to a broad range of future research involving teenage behavior. A specific means is proposed to reconcile DL with previous articles finding no relationship between crime and abortion. PMID:28943645

There is general agreement that uncertainty persists regarding the psychological sequelae of abortion. Inconsistencies of interpretation stem from a lack of consensus about the symptoms, severity, and duration of mental disorder. In addition, opinions differ based on individual case studies and there is no national reporting system or adequate follow up system. Frequently, reviews combine studies conducted prior to and after the 1973 Supreme Court decision, mix elective abortion with those induced for medical reasons, or fail to distinguish between abortions performed early or late in gestation. The literature reveals methodological problems, a lack of controls, and sampling inadequacies. A review of the available literature and the files of "Abortion Research Notes" suggests that women at particular risk for postabortion stress reactions are those who terminate an originally wanted pregnancy, are strongly ambivalent, come very late in their pregnancy, or lack the support of significant others.
Automation of Flight Software Regression Testing
Tashakkor, Scott B.
2016-01-01
NASA is developing the Space Launch System (SLS) to be a heavy lift launch vehicle supporting human and scientific exploration beyond earth orbit. SLS will have a common core stage, an upper stage, and different permutations of boosters and fairings to perform various crewed or cargo missions. Marshall Space Flight Center (MSFC) is writing the Flight Software (FSW) that will operate the SLS launch vehicle. The FSW is developed in an incremental manner based on "Agile" software techniques. As the FSW is incrementally developed, testing the functionality of the code needs to be performed continually to ensure that the integrity of the software is maintained. Manually testing the functionality on an ever-growing set of requirements and features is not an efficient solution and therefore needs to be done automatically to ensure testing is comprehensive. To support test automation, a framework for a regression test harness has been developed and used on SLS FSW. The test harness provides a modular design approach that can compile or read in the required information specified by the developer of the test. The modularity provides independence between groups of tests and the ability to add and remove tests without disturbing others. This provides the SLS FSW team a time saving feature that is essential to meeting SLS Program technical and programmatic requirements. During development of SLS FSW, this technique has proved to be a useful tool to ensure all requirements have been tested, and that desired functionality is maintained, as changes occur. It also provides a mechanism for developers to check functionality of the code that they have developed. With this system, automation of regression testing is accomplished through a scheduling tool and/or commit hooks. Key advantages of this test harness capability includes execution support for multiple independent test cases, the ability for developers to specify precisely what they are testing and how, the ability to add

launch vehicles, in particular to gain experience towing delta-wing aircraft having high wing loading, and in general to demonstrate various operational procedures such as ground processing and abort scenarios. The first successful towed flight occurred on Dec. 20, 1997. Prior to this first tow test flight, the C-141A and EXD-01 were used to conduct a series of tethered taxi tests to validate the tow procedures. Before these tethered taxi tests, a successful joint flight test was conducted in late October 1996, by Dryden, AFFTC, and KST, in which one of the Dryden F-18 chase aircraft flew at various ranges and locations behind the C-141A to define the wake turbulence and wingtip vortex environment. This flight test was replicated in July 1997, with an unmodified QF-106 flight proficiency aircraft.

To assess whether a social marketing initiative focusing on medicated abortion via a mifepristone/misoprostol "combipack" has contributed to reducing unsafe abortion in Cambodia. In a questionnaire-based cross-sectional study, annual household surveys were conducted across 13 Cambodian provinces in 2010, 2011, and 2012. One married woman of reproductive age who was not pregnant and did not wish to be within the next 2 years in each randomly selected household was approached for inclusion. Participants were interviewed using a structured questionnaire. The questionnaire was completed by 1843 women in 2010, 2068 in 2011, and 2059 in 2012. Manual vacuum aspiration was reported by 61 (72.6%) of 84 women surveyed in 2010 who reported an abortion in the previous 12 months, compared with only 28 (52.8%) of 53 in 2012 (P=0.001). The numbers of women undergoing medicated abortion increased from 22 (26.2%) of 84 in 2010 to 27 (49.1%) of 53 in 2012 (P=0.003), whereas the numbers undergoing unsafe abortion decreased from 4 (4.8%) in 2010 to 0 in 2012 (P=0.051). Social marketing of medication abortion coupled with provider training in clinical and behavioral change could have contributed to a reduction in the prevalence of unsafe abortion and shifted the types of abortion performed in Cambodia, while not increasing the overall number of abortions. © 2016 International Federation of Gynecology and Obstetrics.

Development of a test and flight engineering oriented language, phase 3
Kamsler, W. F.; Case, C. W.; Kinney, E. L.; Gyure, J.
1970-01-01
Based on an analysis of previously developed test oriented languages and a study of test language requirements, a high order language was designed to enable test and flight engineers to checkout and operate the proposed space shuttle and other NASA vehicles and experiments. The language is called ALOFT (a language oriented to flight engineering and testing). The language is described, its terminology is compared to similar terms in other test languages, and its features and utilization are discussed. The appendix provides the specifications for ALOFT.

Control of complex Vertical Take-Off and Landing (VTOL) aircraft traversing from hovering to wing born flight mode and back poses notoriously difficult modeling, simulation, control, and flight-testing challenges. This paper provides an overview of the techniques and advances required to develop the GL-10 tilt-wing, tilt-tail, long endurance, VTOL aircraft control system. The GL-10 prototype's unusual and complex configuration requires application of state-of-the-art techniques and some significant advances in wind tunnel infrastructure automation, efficient Design Of Experiments (DOE) tunnel test techniques, modeling, multi-body equations of motion, multi-body actuator models, simulation, control algorithm design, and flight test avionics, testing, and analysis. The following compendium surveys key disciplines required to develop an effective control system for this challenging vehicle in this on-going effort.
Visualising abortion: emotion discourse and fetal imagery in a contemporary abortion debate.
Hopkins, Nick; Zeedyk, Suzanne; Raitt, Fiona
2005-07-01
This paper presents an analysis of a recent UK anti-abortion campaign in which the use of fetal imagery--especially images of fetal remains--was a prominent issue. A striking feature of the texts produced by the group behind the campaign was the emphasis given to the emotions of those viewing such imagery. Traditionally, social scientific analyses of mass communication have problematised references to emotion and viewed them as being of significance because of their power to subvert the rational appraisal of message content. However, we argue that emotion discourse may be analysed from a different perspective. As the categorisation of the fetus is a social choice and contested, it follows that all protagonists in the abortion debate (whether pro- or anti-abortion) are faced with the task of constructing the fetus as a particular entity rather than another, and that they must seek to portray their preferred categorisation as objective and driven by an 'out-there' reality. Following this logic, we show how the emotional experience of viewing fetal imagery was represented so as to ground an anti-abortion construction of the fetus as objective. We also show how the arguments of the (pro-abortion) opposition were construed as totally discrepant with such emotions and so were invalidated as deceitful distortions of reality. The wider significance of this analysis for social scientific analyses of the abortion debate is discussed.

Up to 31st December 1994 all cases of legally induced abortions were notified by the physician responsible for the operation to the National Board of Health and recorded in the Register of Induced Abortions. Following this data, abortion statistics will rely on data concerning induced abortions...... in the Danish National Patient Register, which includes information based upon the unique personal number of all patients admitted to hospitals. The completeness of the Register of Induced Abortions and the National Patient Register as to induced abortions in 1994 was assessed to evaluate the impact...... of the change in method of monitoring on trends in the national and regional abortion rate. The complete number of induced abortions was estimated to be the sum of the number recorded in both registers, cases recorded only in the Register of Induced Abortions, cases recorded only in the National Patient...
Wind-tunnel development of an SR-71 aerospike rocket flight test configuration
Smith, Stephen C.; Shirakata, Norm; Moes, Timothy R.; Cobleigh, Brent R.; Conners, Timothy H.
1996-01-01
A flight experiment has been proposed to investigate the performance of an aerospike rocket motor installed in a lifting body configuration. An SR-71 airplane would be used to carry the aerospike configuration to the desired flight test conditions. Wind-tunnel tests were completed on a 4-percent scale SR-71 airplane with the aerospike pod mounted in various locations on the upper fuselage. Testing was accomplished using sting and blade mounts from Mach 0.6 to Mach 3.2. Initial test objectives included assessing transonic drag and supersonic lateral-directional stability and control. During these tests, flight simulations were run with wind-tunnel data to assess the acceptability of the configurations. Early testing demonstrated that the initial configuration with the aerospike pod near the SR-71 center of gravity was unsuitable because of large nosedown pitching moments at transonic speeds. The excessive trim drag resulting from accommodating this pitching moment far exceeded the excess thrust capability of the airplane. Wind-tunnel testing continued in an attempt to find a configuration suitable for flight test. Multiple configurations were tested. Results indicate that an aft-mounted model configuration possessed acceptable performance, stability, and control characteristics.
Medical abortion reversal: science and politics meet.
Bhatti, Khadijah Z; Nguyen, Antoinette T; Stuart, Gretchen S
2018-03-01
Medical abortion is a safe, effective, and acceptable option for patients seeking an early nonsurgical abortion. In 2014, medical abortion accounted for nearly one third (31%) of all abortions performed in the United States. State-level attempts to restrict reproductive and sexual health have recently included bills that require physicians to inform women that a medical abortion is reversible. In this commentary, we will review the history, current evidence-based regimen, and regulation of medical abortion. We will then examine current proposed and existing abortion reversal legislation. The objective of this commentary is to ensure physicians are armed with rigorous evidence to inform patients, communities, and policy makers about the safety of medical abortion. Furthermore, given the current paucity of evidence for medical abortion reversal, physicians and policy makers can dispel bad science and misinformation and advocate against medical abortion reversal legislation.

Constructing abortion as a social problem: “Sex selection” and the British abortion debate
2017-01-01
Between February 2012 and March 2015, the claim that sex selection abortion was taking place in Britain and that action needed to be taken to stop it dominated debate in Britain about abortion. Situating an analysis in sociological and social psychological approaches to the construction of social problems, particularly those considering “feminised” re-framings of anti-abortion arguments, this paper presents an account of this debate. Based on analysis of media coverage, Parliamentary debate and official documents, we focus on claims about grounds (evidence) made to sustain the case that sex selection abortion is a British social problem and highlight how abortion was problematised in new ways. Perhaps most notable, we argue, was the level of largely unchallenged vilification of abortion doctors and providers, on the grounds that they are both law violators and participants in acts of discrimination and violence against women, especially those of Asian heritage. We draw attention to the role of claims made by feminists in the media and in Parliament about “gendercide” as part of this process and argue that those supportive of access to abortion need to critically assess both this aspect of the events and also consider arguments about the problems of “medical power” in the light of what took place.

2005-01-01
The objective of the Hyper-X program was to flight demonstrate an airframe-integrated hypersonic vehicle. On March 27, 2004, the Hyper-X program team successfully conducted flight 2 and achieved all of the research objectives. The Hyper-X research vehicle successfully separated from the Hyper-X launch vehicle and achieved the desired engine test conditions before the experiment began. The research vehicle rejected the disturbances caused by the cowl door opening and the fuel turning on and off and maintained the engine test conditions throughout the experiment. After the engine test was complete, the vehicle recovered and descended along a trajectory while performing research maneuvers. The last data acquired showed that the vehicle maintained control to the water. This report will provide an overview of the research vehicle guidance and control systems and the performance of the vehicle during the separation event and engine test. The research maneuvers were performed to collect data for aerodynamics and flight controls research. This report also will provide an overview of the flight controls related research and results.
Stewardship challenges abortion: A proposed means to mitigate abortion's social divisiveness.
Tardiff, Robert G
2015-08-01
Since 1973 the legislated constitutional right to abortion has produced a political dichotomy (anti-abortion versus pro-abortion) within the United States, even while witnessing a gradual decline in the rate of abortions. A third paradigm, moral stewardship, is advanced as an effective means to ameliorate this social divisiveness. Incorporating the concept of stewardship into deliberations of pregnancy termination would require recognition, through fact-based education programs, of the life circumstances that prompt the consideration to terminate a pregnancy. Based on collective responsibility, policies, and programs are needed to foster social justice for parents and for the offspring brought to term, without creating excessive burdens on women faced with an unwanted pregnancy. Moral stewardship is perceived as humanitarian to family and community and advantageous to society overall. It also offers a serious opportunity to reshape our society from divisiveness to inclusiveness, and to guide science policy judgment that enhances and strengthens social justice. Lay summary: Differing opinions over the ethics of human abortion have been legion since Roe v. Wade (1973). The disputes between pro- and anti-abortion factions have segregated society with few improvements in social justice. This study offers an alternative approach, one capable of social assimilation and justice for unwanted offspring and pregnant mothers bearing them. It promotes moral stewardship toward the unborn whose humanity and personhood are recognized genetically and supported philosophically by long-standing ethical principles. Stewardship incorporates all people at all levels of society based on collective responsibility, supported by government policies, yet not restricting a mother's choices for the future of her unborn offspring.

Attitudes toward abortion in Zambia.
Geary, Cynthia Waszak; Gebreselassie, Hailemichael; Awah, Paschal; Pearson, Erin
2012-09-01
Despite Zambia's relatively progressive abortion law, women continue to seek unsafe, illegal abortions. Four domains of abortion attitudes - support for legalization, immorality, rights, and access to services - were measured in 4 communities. A total of 668 people were interviewed. Associations among the 4 domains were inconsistent with expectations. The belief that abortion is immoral was widespread, but was not associated with lack of support for legalization. Instead, it was associated with belief that women need access to safe services. These findings suggest that increasing awareness about abortion law in Zambia may be important for encouraging more favorable attitudes.

Korejo, R.; Noorani, K.J.; Bhutta, S.
2003-01-01
Objective: To determine the frequency of induced abortion and identity the role of sociocultural factors contributing to termination of pregnancy and associated morbidity and mortality in hospital setting. Subjects and Methods: The patients who were admitted for induced abortion were interviewed in privacy. On condition of anonymity they were asked about the age, parity, family setup and relationships, with particular emphasis on sociocultural reasons and factors contributing to induction of abortion. Details of status of abortionist and methods used for termination of pregnancy, the resulting complications and their severity were recorded. Results: Out of total admissions, 57(2.35%) gave history of induced abortion. All women belonged to low socioeconomic class and 59.6% of them were illiterate. Forty-three (75.5%) of these women had never practiced concentration. Twenty-four (42%) were grandmultiparae and did not want more children. In 29 women (50.9%) the decision for abortion had been supported by the husband. In 25 (43.8%) abortion was carried out by Daiyan (traditional midwives). Serious complications like uterine perforation with or without bowel injury were encouraged in 25 (43.8%) of these women. During the study period illegally induced abortion accounted for 6 (10.5%) maternal deaths. Conclusion: Prevalence of poverty, illiteracy, grand multiparity and non-practice of contraception are strong determinants of induced abortion. (author)

The Synthetic and Enhanced Vision Systems for NextGen (SEVS) simulation and flight tests are jointly sponsored by NASA's Aviation Safety Program, Vehicle Systems Safety Technology project and the Federal Aviation Administration (FAA). The flight tests were conducted by a team of Honeywell, Gulfstream Aerospace Corporation and NASA personnel with the goal of obtaining pilot-in-the-loop test data for flight validation, verification, and demonstration of selected SEVS operational and system-level performance capabilities. Nine test flights (38 flight hours) were conducted over the summer and fall of 2011. The evaluations were flown in Gulfstream.s G450 flight test aircraft outfitted with the SEVS technology under very low visibility instrument meteorological conditions. Evaluation pilots flew 108 approaches in low visibility weather conditions (600 ft to 2400 ft visibility) into various airports from Louisiana to Maine. In-situ flight performance and subjective workload and acceptability data were collected in collaboration with ground simulation studies at LaRC.s Research Flight Deck simulator.

Is Induced Abortion Really Declining in Armenia?
Jilozian, Ann; Agadjanian, Victor
2016-06-01
As in other post-Soviet settings, induced abortion has been widely used in Armenia. However, recent national survey data point to a substantial drop in abortion rates with no commensurate increase in modern contraceptive prevalence and no change in fertility levels. We use data from in-depth interviews with women of reproductive age and health providers in rural Armenia to explore possible underreporting of both contraceptive use and abortion. While we find no evidence that women understate their use of modern contraception, the analysis suggests that induced abortion might indeed be underreported. The potential for underreporting is particularly high for sex-selective abortions, for which there is growing public backlash, and medical abortion, a practice that is typically self-administered outside any professional supervision. Possible underreporting of induced abortion calls for refinement of both abortion registration and relevant survey instruments. Better measurement of abortion dynamics is necessary for successful promotion of effective modern contraceptive methods and reduction of unsafe abortion practices. © 2016 The Population Council, Inc.
[Legal and illegal abortion in Switzerland].
Stamm, H
1970-01-01
Aspects of legal and illegal abortion in Switzerland are discussed. About 110,000 births, 25,000 therapeutic abortions (75% for psychiatric indications) and an estimated 50,000 illegal abortions occur annually in Switzerland. Although the mortality and morbidity of therapeutic aborti on are similar to those of normal births (1.4 per 1000 and 11%, respectively) the mortality and morbidity of criminal abortions are far greater (3 per 1000 and 73%, respectively). In the author's view, too strict an interpretatiok of Swiss abortion law (which permits abortion to avoid serious harm to the mother's health) does not take into account the severe and lasting emotional and psychological damage which may be caused by unwanted pregnancy, birth, and childraising. In the present social situation, the social and psychological support required by these women is not available; until it is, abortion is to be preferred.
Ares-I-X Stability and Control Flight Test: Analysis and Plans
Brandon, Jay M.; Derry, Stephen D.; Heim, Eugene H.; Hueschen, Richard M.; Bacon, Barton J.
2008-01-01
The flight test of the Ares I-X vehicle provides a unique opportunity to reduce risk of the design of the Ares I vehicle and test out design, math modeling, and analysis methods. One of the key features of the Ares I design is the significant static aerodynamic instability coupled with the relatively flexible vehicle - potentially resulting in a challenging controls problem to provide adequate flight path performance while also providing adequate structural mode damping and preventing adverse control coupling to the flexible structural modes. Another challenge is to obtain enough data from the single flight to be able to conduct analysis showing the effectiveness of the controls solutions and have data to inform design decisions for Ares I. This paper will outline the modeling approaches and control system design to conduct this flight test, and also the system identification techniques developed to extract key information such as control system performance (gain/phase margins, for example), structural dynamics responses, and aerodynamic model estimations.
Clandestine abortions are not necessarily illegal.
Cook, R J
1991-01-01
It is common to find the term illegal abortion misused. Often times this misuse is perpetrated by antiabortion advocates who wish to reinforce negative stereotypes and thus apply pressure on doctors to refrain from performing abortions. Until a practitioner is prosecuted and convicted of performing an abortion contrary to the law, the procedure should not be referred to as illegal. Instead the legally neutral term, abortion, should be used instead. This would better serve the interests of women's reproductive health. There is no legal system that makes abortion illegal in all circumstances. For example, abortion is often legal if the life of the mother in danger. This includes a perception on behalf of the practitioner that the women may be suicidal or attempt to terminate the pregnancy by herself. A practitioner performing an abortion in such circumstances is not doing so illegally. The use of the term illegal abortion ignores the fact that in criminal law one is presumed innocent until proven guilty. A prosecutor must prove 1st that an intervention was performed and 2nd that a criminal intent accompanied the intervention. It is this 2nd criterion that is often the hardest to prove, since the practitioner must only testify that the intervention was indicated by legally allowed circumstances to be innocent. The prosecutor must show bad faith in order to gain a justified conviction. Even abortion by unqualified practitioners may not be illegal if doctors refuse to perform the intervention because it is still indicated. Accurate description of abortions would clarify situations in which abortion can be legally provided.
Reproductive tract infections in women seeking abortion in Vietnam

Full Text Available Abstract Background Women requesting abortion are at increased risk of developing RTI complications. However, RTI control in many resource-poor countries including Vietnam have been faced with logistical and methodological problems due to lack of standardized definitions of RTIs, lack of well-validated diagnostic criteria, lack of accurate laboratory tests, and lack of diagnostic equipment and skills. This article investigates the prevalence of RTIs among Vietnamese abortion-seeking women, to evaluate the available diagnostic techniques, and to assess antibiotic resistance among aetiological agents of RTI. Method The study was conducted in Phu-San hospital (PSH from December 2003 through April 2004 among 748 abortion clients. A structured questionnaire was used to collect data on socio-economic and reproductive characteristics. Specimens were collected for laboratory analyses of chlamydia, gonorrhoea, trichomoniasis, vaginal candidiasis (VC, bacterial vaginosis (BV and syphilis. To assess the validity of the obtained results, the study was repeated among 100 women and the duplicate samples were analysed at PSH and Copenhagen University Hospital (CUH. Results In all 54% of the women were diagnosed as having an RTI, including 3.3% with sexually transmitted infections. Endogenous infections were most prevalent (VC 34% and BV 12% followed by chlamydia (1.3% and trichomoniasis (0.7%. The sensitivity of culture for VC and BV was 30% and 88%, respectively, when tests in PSH were measured against tests in CUH. Antibiotic resistance was common among bacterial isolates. Conclusion RTIs are common among women seeking abortion. The presence of RTIs is associated with an increased risk of developing iatrogenic infections, routine administration of prophylactic antibiotic to all women undergoing abortion should be considered. However, the choice of routine prophylactic antibiotics should be based on relevant surveillance data of antibiotic resistance

countries where women do not have legal access to abortion. Postabortion care focuses on treatment of incomplete abortion and provision of postabortion contraceptive services. To enhance women's access to postabortion care, focus is increasingly being placed on upgrading midlevel providers to provide......Forty percent of the world's women are living in countries with restrictive abortion laws, which prohibit abortion or only allow abortion to protect a woman's life or her physical or mental health. In countries where abortion is restricted, women have to resort to clandestine interventions to have...... an unwanted pregnancy terminated. As a consequence, high rates of unsafe abortion are seen, such as in sub-Saharan Africa where unsafe abortion occurs at rates of 18-39/1 000 women.

Abortion checks at German-Dutch border.
Von Baross, J
1991-05-01
The commentary on West German abortion law, particularly in illegal abortion in the Netherlands, finds the law restrictive and in violation of the dignity and rights of women. The Max-Planck Institute in 1990 published a study that found that a main point of prosecution between 1976 and 1986, as reported by Der Spiegal, was in border crossings from the Netherlands. It is estimated that 10,000 annually have abortions abroad, and 6,000 to 7,000 in the Netherlands. The procedure was for an official to stop a young person and query about drugs; later the woman would admit to an abortion, and be forced into a medical examination. The German Penal Code Section 218 stipulates abortion only for certain reasons testified to by a doctor other than the one performing the abortion. Counseling on available social assistance must be completed 3 days prior to the abortion. Many counseling offices are church related and opposed to abortions. Many doctors refuse legally to certify, and access to abortion is limited. The required hospital stay is 3-4 nights with no day care facilities. Penal Code Section 5 No. 9 allows prosecution for uncounseled illegal abortion. Abortion law reform is anticipated by the end of 1992 in the Bundestag due to the Treaty or the Unification of Germany. The Treaty states that the rights of the unborn child must be protected and that pregnant women relieve their distress in a way compatible with the Constitution, but improved over legal regulations from either West or East Germany, which permits abortion on request within 12 weeks of conception without counseling. It is hoped that the law will be liberalized and Penal Code Section 5 No. 9 will be abolished.
Flight Test Results from the Rake Airflow Gage Experiment on the F-15B Airplane
Frederick, Michael A.; Ratnayake, Nalin A.
2011-01-01
The Rake Airflow Gage Experiment involves a flow-field survey rake that was flown on the Propulsion Flight Test Fixture at the NASA Dryden Flight Research Center using the Dryden F-15B research test bed airplane. The objective of this flight test was to ascertain the flow-field angularity, local Mach number profile, total pressure distortion, and dynamic pressure at the aerodynamic interface plane of the Channeled Centerbody Inlet Experiment. This new mixed-compression, supersonic inlet is planned for flight test in the near term. Knowledge of the flow-field characteristics at this location underneath the airplane is essential to flight test planning and computational modeling of the new inlet, anairplane, flying at a free-stream Mach number of 1.65 and a pressure altitude of 40,000 ft, would achieve the desired local Mach number for the future inlet flight test. Interface plane distortion levels of 2 percent and a local angle of attack of -2 deg were observed at this condition. Alternative flight conditions for future testing and an exploration of certain anomalous data also are provided.

To determine the frequency of induced abortion and identify the role of sociocultural factors contributing to termination of pregnancy and associated morbidity and mortality in hospital setting. Prospective observational study. The study was conducted in the Department of Obstetrics and Gynaecology, Jinnah Postgraduate Medical Centre, Karachi from January 1999 to June 2001. The patients who were admitted for induced abortion were interviewed in privacy. On condition of anonymity they were asked about the age, parity, family setup and relationships, with particular emphasis on sociocultural reasons and factors contributing to induction of abortion. Details of status of abortionist and methods used for termination of pregnancy, the resulting complications and their severity were recorded. Out of total admissions, 57(2.35%) gave history of induced abortion. All women belonged to low socioeconomic class and 59.6% of them were illiterate. Forty-three (75.5%) of these women had never practiced contraception. Twenty-four (42%) were grandmultiparae and did not want more children. In 29 women (50.9%) the decision for abortion had been supported by the husband. In 25 women (43.8%) abortion was carried out by Daiyan (traditional midwives). Serious complications like uterine perforation with or without bowel injury were encountered in 25 (43.8%) of these women. During the study period illegally induced abortion accounted for 6 (10.5%) maternal deaths. Prevalence of poverty, illiteracy, grand multiparity and non-practice of contraception are strong determinants of induced abortion.
Abortion: Still Unfinished Agenda in Nepal.

Unsafe abortion is affecting a lot, in health, socio-economic and health care cost of many countries. Despite invention of simple technology and scientifically approved safe abortion methods, women and girls are still using unsafe abortion practices. Since 2002, Nepal has achieved remarkable progress in developing policies, guidelines, task shifting, training human resources and increasing access to services. However, more than half of abortion in Nepal are performed clandestinely by untrained or unapproved providers or induced by pregnant woman herself. Knowledge on legalization and availability of safe abortion service among women is still very poor. Stigma on abortion still persists among community people, service providers, managers, and policy makers. Access to safe abortion, especially in remote and rural areas, is still far behind as compared to their peers from urban areas. The existing law is not revised in the spirit of current Constitution of Nepal and rights-based approach. The existence of abortion stigma and the shifting of the government structure from unitary system to federalism in absence of a complete clarity on how the safe abortion service gets integrated into the local government structure might create challenge to sustain existing developments. There is, therefore, a need for all stakeholders to make a lot of efforts and allocate adequate resources to sustain current achievements and ensure improvements in creating a supportive social environment for women and girls so that they will be able to make informed decisions and access to safe abortion service in any circumstances.
Rotary Balance Wind Tunnel Testing for the FASER Flight Research Aircraft
Denham, Casey; Owens, D. Bruce
2016-01-01
Flight dynamics research was conducted to collect and analyze rotary balance wind tunnel test data in order to improve the aerodynamic simulation and modeling of a low-cost small unmanned aircraft called FASER (Free-flying Aircraft for Sub-scale Experimental Research). The impetus for using FASER was to provide risk and cost reduction for flight testing of more expensive aircraft and assist in the improvement of wind tunnel and flight test techniques, and control laws. The FASER research aircraft has the benefit of allowing wind tunnel and flight tests to be conducted on the same model, improving correlation between wind tunnel, flight, and simulation data. Prior wind tunnel tests include a static force and moment test, including power effects, and a roll and yaw damping forced oscillation test. Rotary balance testing allows for the calculation of aircraft rotary derivatives and the prediction of steady-state spins. The rotary balance wind tunnel test was conducted in the NASA Langley Research Center (LaRC) 20-Foot Vertical Spin Tunnel (VST). Rotary balance testing includes runs for a set of given angular rotation rates at a range of angles of attack and sideslip angles in order to fully characterize the aircraft rotary dynamics. Tests were performed at angles of attack from 0 to 50 degrees, sideslip angles of -5 to 10 degrees, and non-dimensional spin rates from -0.5 to 0.5. The effects of pro-spin elevator and rudder deflection and pro- and anti-spin elevator, rudder, and aileron deflection were examined. The data are presented to illustrate the functional dependence of the forces and moments on angle of attack, sideslip angle, and angular rate for the rotary contributions to the forces and moments. Further investigation is necessary to fully characterize the control effectors. The data were also used with a steady state spin prediction tool that did not predict an equilibrium spin mode.

This paper describes the ultrasonic testing using Time Flight Diffraction (TOFD) Technique for welded samples having different types and sizes of defects. TOFD is a computerized ultrasonic system, able to scan, store and evaluate indications in terms of location, through thickness and length in a more easy and convenient. Time of Flight Diffraction Technique (TOFD) is more fast and easy technique for ultrasonic testing as we can examine a weld i a single scan along the length of the weld with two probes known as D-scan. It shows the image of the complete weld with the defect information. The examinations were performed on carbon steel samples used for ultrasonic testing using 70 degree probes. The images for different type of defects were obtained. (author)
Stigma and abortion complications in the United States.
Harris, Lisa H
2012-12-01
Abortion is highly stigmatized in the United States and elsewhere. As a result, many women who seek or undergo abortion keep their decision a secret. In many regions of the world, stigma is a recognized contributor to maternal morbidity and mortality from unsafe abortion, even when abortion is legal. Women may self-induce abortion in ways that are dangerous, or seek unsafe clandestine abortion from inadequately trained health care providers out of fear that their sexual activity, pregnancy, or abortion will be exposed if they present to a safe, licensed facility. However, unsafe abortion rarely occurs in the United States, and accordingly, stigma as a cause of unsafe abortion in the United States context has not been described. I consider the relationship of stigma to two serious abortion complications experienced by U.S. patients. Both patients wished to keep their abortion decision a secret from family and friends, and in both cases, their inability to disclose their abortion contributed to life-threatening complications. The experiences of these patients suggest that availability of legal abortion services in the United States may not be enough to keep all women safe. The cases also challenge the rhetoric that "abortion hurts women," suggesting instead that abortion stigma hurts women.
Abortion related stigma: a case study of abortion stigma in regions ...

In Scotland, in contrast to the rest of Great Britain, abortion at gestations over 20 weeks is not provided, and provision of procedures above 16 weeks varies considerably between regions. Women at varying gestations above 16 weeks must travel outside Scotland, usually to England, for the procedure. To determine the views of professionals working within Scottish abortion care about a Scottish late abortion service. Delegates at a meeting for abortion providers in Scotland completed a questionnaire about their views on abortion provision over 16 weeks and their perceived barriers to service provision. Of 95 distributed questionnaires, 70 (76%) were analysed. Fifty-six respondents (80%) supported a Scottish late abortion service, ten (14%) would maintain current service arrangements, and five (7%) were undecided. Forty (57%) of the supporters of a Scottish service would prefer a single national service, and 16 (22%) several regional services. Perceived barriers included lack of trained staff (n = 39; 56%), accommodation for the service (n = 34; 48%), and perception of lack of support among senior management (n = 28; 40%). The majority of health professionals surveyed who work in Scottish abortion services support provision of abortion beyond 16 weeks within Scotland, and most favour a single national service. Further work on the feasibility of providing this service is required.
The Impact of Legalized Abortion on Crime
John Donohue; Steven Levitt
2000-01-01
We offer evidence that legalized abortion has contributed significantly to recent crime reductions. Crime began to fall roughly 18 years after abortion legalization. The 5 states that allowed abortion in 1970 experienced declines earlier than the rest of the nation, which legalized in 1973 with Roe v. Wade. States with high abortion rates in the 1970s and 1980s experienced greater crime reductions in the 1990s. In high abortion states, only arrests of those born after abortion legaliz...
Evidence supporting broader access to safe legal abortion.
Faúndes, Anibal; Shah, Iqbal H
2015-10-01
Unsafe abortion continues to be a major cause of maternal death; it accounts for 14.5% of all maternal deaths globally and almost all of these deaths occur in countries with restrictive abortion laws. A strong body of accumulated evidence shows that the simple means to drastically reduce unsafe abortion-related maternal deaths and morbidity is to make abortion legal and institutional termination of pregnancy broadly accessible. Despite this evidence, abortion is denied even when the legal condition for abortion is met. The present article aims to contribute to a better understanding that one can be in favor of greater access to safe abortion services, while at the same time not be "in favor of abortion," by reviewing the evidence that indicates that criminalization of abortion only increases mortality and morbidity without decreasing the incidence of induced abortion, and that decriminalization rapidly reduces abortion-related mortality and does not increase abortion rates.

There has been continued interest in the extent to which women have positive and negative reactions to abortion. To document emotional reactions to abortion, and to examine the links between reactions to abortion and subsequent mental health outcomes. Data were gathered on the pregnancy and mental health history of a birth cohort of over 500 women studied to the age of 30. Abortion was associated with high rates of both positive and negative emotional reactions; however, nearly 90% of respondents believed that the abortion was the right decision. Analyses showed that the number of negative responses to the abortion was associated with increased levels of subsequent mental health disorders (Pabortion and reporting negative reactions had rates of mental health disorders that were approximately 1.4-1.8 times higher than those not having an abortion. Abortion was associated with both positive and negative emotional reactions. The extent of negative emotional reactions appeared to modify the links between abortion and subsequent mental health problems.
New German abortion law agreed.
Karcher, H L
1995-07-15
The German Bundestag has passed a compromise abortion law that makes an abortion performed within the first three months of pregnancy an unlawful but unpunishable act if the woman has sought independent counseling first. Article 218 of the German penal code, which was established in 1871 under Otto von Bismarck, had allowed abortions for certain medical or ethical reasons. After the end of the first world war, the Social Democrats tried to legalize all abortions performed in the first three months of pregnancy, but failed. In 1974, abortion on demand during the first 12 weeks was declared legal and unpunishable under the social liberal coalition government of chancellor Willy Brandt; however, the same year, the German Federal Constitution Court in Karlsruhe ruled the bill was incompatible with article 2 of the constitution, which guarantees the right to life and freedom from bodily harm to everyone, including the unborn. The highest German court also ruled that a pregnant woman had to seek a second opinion from an independent doctor before undergoing an abortion. A new, extended article 218, which included a clause giving social indications, was passed by the Bundestag. When Germany was unified, East Germans agreed to be governed by all West German laws, except article 218. The Bundestag was given 2 years to revise the article; however, in 1993, the Federal Constitution Court rejected a version legalizing abortion in the first 3 months of the pregnancy if the woman sought counsel from an independent physician, and suggested the recent compromise passed by the Bundestag, the lower house of the German parliament. The upper house, the Bundesrat, where the Social Democrats are in the majority, still has to pass it. Under the bill passed by the Bundestag, national health insurance will pay for an abortion if the monthly income of the woman seeking the abortion falls under a certain limit.
[Abortion. Spain: the keys to the controversy].
1983-01-01
For many years, illegal abortion has been denounced in Spain. The estimate of 300,000 abortions annually is widely quoted but poorly founded in fact. Weekend "charters" to London and Amsterdam for women seeking abortions have been commented upon, denounced, and caricatured. The evidence indicates that abortions occur in Spain despite their illegality, just as they occur in every other country and have always occurred. Poor women abort in a poor way, with traditional healers, while rich women abort in a rich way, with physicians. "Charters" are the solution of the middle class. Proposed legislation in Spain would permit abortion on 3 grounds: rape, fetal malformation, and risk to the woman's life if the pregnancy continued. Excesses have been committed both by those opposing abortion and by those struggling for liberalization of laws. Defenders of abortion, such as radical feminists, appear to forget that abortion is a medical procedure with possible dangerous psychophysical consequences, and that preventive measures such as sex education and diffusion of contraception or social measures such as assistance for unwed mothers and their children would be preferrable to abortion. There is the question of whether medical personnel should be excused from assisting in abortions on grounds of conscience and whether those who do assist in abortions automatically become "progressive" by doing so. The staunchest defenders of fetal life are not moved to contribute anything beyond words to improvement of the plight of the many millions of already born who live in miserable conditions of hunger and want. Abortion is a violent act against the fetus and the pregnant woman. Its criminalization is a violent act against the woman and a social intrusion into matters better left to personal ethics. The government which proposes abortion on a few grounds fails to initiate a program to promote life through social protection of single mothers and their children or of families in general

A flight management algorithm designed to improve the accuracy of delivering the airplane fuel efficiently to a metering fix at a time designated by air traffic control is discussed. The algorithm provides a 3-D path with time control (4-D) for a test B 737 airplane to make an idle thrust, clean configured descent to arrive at the metering fix at a predetermined time, altitude, and airspeed. The descent path is calculated for a constant Mach/airspeed schedule from linear approximations of airplane performance with considerations given for gross weight, wind, and nonstandard pressure and temperature effects. The flight management descent algorithms and the results of the flight tests are discussed.

Across four decades of political and social action, Nepal changed from a country strongly enforcing oppressive abortion restrictions, causing many poor women's long imprisonment and high rates of abortion-related maternal mortality, into a modern democracy with a liberal abortion law. The medical and public health communities supported women's rights activists in invoking legal principles of equality and non-discrimination as a basis for change. Legislative reform of the criminal ban in 2002 and the adoption of an Interim Constitution recognizing women's reproductive rights as fundamental rights in 2007 inspired the Supreme Court in 2009 to rule that denial of women's access to abortion services because of poverty violated their constitutional rights. The government must now provide services under criteria for access without charge, and services must be decentralized to promote equitable access. A strong legal foundation now exists for progress in social justice to broaden abortion access and reduce abortion stigma. Copyright © 2014 International Federation of Gynecology and Obstetrics.

Marshall Space Flight Center's Impact Testing Facility Capabilities
Finchum, Andy; Hubbs, Whitney; Evans, Steve
2008-01-01
Marshall Space Flight Center s (MSFC) Impact Testing Facility (ITF) serves as an important installation for space and missile related materials science research. The ITF was established and began its research in spacecraft debris shielding in the early 1960s, then played a major role in the International Space Station debris shield development. As NASA became more interested in launch debris and in-flight impact concerns, the ITF grew to include research in a variety of impact genres. Collaborative partnerships with the DoD led to a wider range of impact capabilities being relocated to MSFC as a result of the closure of Particle Impact Facilities in Santa Barbara, California. The Particle Impact Facility had a 30 year history in providing evaluations of aerospace materials and components during flights through rain, ice, and solid particle environments at subsonic through hypersonic velocities. The facility s unique capabilities were deemed a "National Asset" by the DoD. The ITF now has capabilities including environmental, ballistic, and hypervelocity impact testing utilizing an array of air, powder, and two-stage light gas guns to accommodate a variety of projectile and target types and sizes. Numerous upgrades including new instrumentation, triggering circuitry, high speed photography, and optimized sabot designs have been implemented. Other recent research has included rain drop demise characterization tests to obtain data for inclusion in on-going model development. The current and proposed ITF capabilities range from rain to micrometeoroids allowing the widest test parameter range possible for materials investigations in support of space, atmospheric, and ground environments. These test capabilities including hydrometeor, single/multi-particle, ballistic gas guns, exploding wire gun, and light gas guns combined with Smooth Particle Hydrodynamics Code (SPHC) simulations represent the widest range of impact test capabilities in the country.

This paper presents an overview of the Cryogenic Test Bed (CTB) experiments including experiment results, integration techniques used, and lessons learned during integration, test and flight phases of the Cryogenic Heat Pipe Flight Experiment (STS-53) and the Cryogenic Two Phase Flight Experiment (OAST-2, STS-62). We will also discuss the Cryogenic Flexible Diode Heat Pipe (CRYOFD) experiment which will fly in the 1996/97 time frame and the fourth flight of the CTB which will fly in the 1997/98 time frame. The two missions tested two oxygen axially grooved heat pipes, a nitrogen fibrous wick heat pipe and a 2-methylpentane phase change material thermal storage unit. Techniques were found for solving problems with vibration from the cryo-collers transmitted through the compressors and the cold heads, and mounting the heat pipe without introducing parasitic heat leaks. A thermally conductive interface material was selected that would meet the requirements and perform over the temperature range of 55 to 300 K. Problems are discussed with the bi-metallic thermostats used for heater circuit protection and the S-Glass suspension straps originally used to secure the BETSU PCM in the CRYOTP mission. Flight results will be compared to 1-g test results and differences will be discussed.
The effect of abortion legalization on sexual behavior: evidence from sexually transmitted diseases.
Klick, Jonathan; Stratmann, Thomas
2003-06-01
Unwanted pregnancy represents a major cost of sexual activity. When abortion was legalized in a number of states in 1969 and 1970 (and nationally in 1973), this cost was reduced. We predict that abortion legalization generated incentives leading to an increase in sexual activity, accompanied by an increase in sexually transmitted diseases (STDs). Using Centers for Disease Control data on the incidence of gonorrhea and syphilis by state, we test the hypothesis that abortion legalization led to an increase in sexually transmitted diseases. We find that gonorrhea and syphilis incidences are significantly and positively correlated with abortion legalization. Further, we find a divergence in STD rates among early legalizing states and late legalizing states starting in 1970 and a subsequent convergence after the Roe v. Wade decision, indicating that the relation between STDs and abortion is casual. Abortion legalization accounts for about one-fourth of the average disease incidence.
The Roman Catholic position on abortion.
Barry, R
1997-01-01
This article presents the history and grounds of the official position of the Roman Catholic Church that abortion under any circumstances, including abortion to save the life of the mother, should be prohibited. After an introduction that deplores the lack of mercy shown to killers of abortionists while Catholic priests threatened by pro-abortion forces are not offered protection, the article traces the historic development of the Catholic abortion policy and rebuts arguments that abortion was permitted in the early Christian Church. The next section explains Catholic views on the personhood of a conceptus and refutes the contentions of Joseph Donceel that early abortion should be permitted because of uncertainty about the nature of the conceptus and the possibility of delayed animation. The fourth section of the paper debates the points raised by Susan Teft Nicholson who maintains that the Catholic position regarding abortion rests on the Church's animosity towards sexual pleasure. The paper goes on to criticize Nicholson's claims that the Roman Catholic position on abortion is inconsistent with the Church's own understanding of the Principle of Double Effect because the Church fails to allow abortion in many cases where it would be permissible under the Principle. Section 6 describes the underlying motive of the Roman Catholic Church's abortion position as an attempt to protect the innocent fetus from deliberate death and to justify the Church's application of protection from deliberate killing to those who are innocent of aggressive action. This discussion is followed by a justification of the Church's prohibition of abortion in cases of aggression, such as the aggression ascribed to a fetus when a pregnancy imperials the life of a mother. It is concluded that the US will likely legalize suicide and mercy killing as it has the killing of innocent fetuses who are probably ensouled with personhood and are not formal aggressors.

To analyse the post-abortion effect of long-acting reversible contraception (LARC) plans and initiation on the risk of subsequent unwanted pregnancy and abortion. retrospective cohort study of 666 women who underwent medical abortion between January-May 2013 at Helsinki University Hospital, Finland. Altogether 159 (23.8%) women planning post-abortion use of levonorgestrel-releasing intrauterine system (LNG-IUS) participated in a randomized study and had an opportunity to receive the LNG-IUS free-of-charge from the hospital. The other 507 (76.2%) women planned and obtained their contraception according to clinical routine. Demographics, planned contraception, and LARC initiation at the time of the index abortion were collected. Data on subsequent abortions were retrieved from the Finnish Abortion Register and electronic patient files until the end of 2014. During the 21 months ([median], IQR 20-22) follow-up, 54(8.1%) women requested subsequent abortions. When adjusted for age, previous pregnancies, deliveries, induced abortions and gestational-age, planning LARC for post-abortion contraception failed to prevent subsequent abortion (33 abortions/360 women, 9.2%) compared to other contraceptive plans (21/306, 6.9%) (HR 1.22, 95% CI 0.68-2.17). However, verified LARC initiation decreased the abortion rate (4 abortions/177 women, 2.3%) compared to women with uncertain LARC initiation status (50/489, 10.2%) (HR 0.17, 95% CI 0.06-0.48). When adjusted for LARC initiation status, age abortion (27 abortions/283 women, 9.5%) compared to women ≥25 years (27/383, 7.0%, HR1.95, 95% CI 1.04-3.67). Initiation of LARC as part of abortion service at the time of medical abortion is an important means to prevent subsequent abortion, especially among young women.

This paper details the post-flight navigation performance assessment of the Orion Exploration Flight Test-1 (EFT-1). Results of each flight phase are presented: Ground Align, Ascent, Orbit, and Entry Descent and Landing. This study examines the on-board Kalman Filter uncertainty along with state deviations relative to the Best Estimated Trajectory (BET). Overall the results show that the Orion Navigation System performed as well or better than expected. Specifically, the Global Positioning System (GPS) measurement availability was significantly better than anticipated at high altitudes. In addition, attitude estimation via processing GPS measurements along with Inertial Measurement Unit (IMU) data performed very well and maintained good attitude throughout the mission.
A new method for flight test determination of propulsive efficiency and drag coefficient
Bull, G.; Bridges, P. D.
1983-01-01
A flight test method is described from which propulsive efficiency as well as parasite and induced drag coefficients can be directly determined using relatively simple instrumentation and analysis techniques. The method uses information contained in the transient response in airspeed for a small power change in level flight in addition to the usual measurement of power required for level flight. Measurements of pitch angle and longitudinal and normal acceleration are eliminated. The theoretical basis for the method, the analytical techniques used, and the results of application of the method to flight test data are presented.
Medical students' attitudes toward abortion education: Malaysian perspective.
Directory of Open Access Journals (Sweden)
Nai-peng Tey
Full Text Available BACKGROUND: Abortion is a serious public health issue, and it poses high risks to the health and life of women. Yet safe abortion services are not readily available because few doctors are trained to provide such services. Many doctors are unaware of laws pertaining to abortion. This article reports survey findings on Malaysian medical students' attitudes toward abortion education and presents a case for including abortion education in medical schools. METHODS AND RESULTS: A survey on knowledge of and attitudes toward abortion among medical students was conducted in two public universities and a private university in Malaysia in 2011. A total of 1,060 students returned the completed questionnaires. The survey covered about 90% of medical students in Years 1, 3, and 5 in the three universities. About 90% of the students wanted more training on the general knowledge and legal aspects of abortion, and pre-and post-abortion counseling. Overall, 75.9% and 81.0% of the students were in favor of including in medical education the training on surgical abortion techniques and medical abortion, respectively. Only 2.4% and 1.7% were opposed to the inclusion of training of these two methods in the curriculum. The remaining respondents were neutral in their stand. Desire for more abortion education was associated with students' pro-choice index, their intention to provide abortion services in future practice, and year of study. However, students' attitudes toward abortion were not significantly associated with gender, type of university, or ethnicity. CONCLUSIONS: Most students wanted more training on abortion. Some students also expressed their intention to provide abortion counseling and services in their future practice. Their desire for more training on abortion should be taken into account in the new curriculum. Abortion education is an important step towards making available safe abortion services to enable women to exercise their reproductive rights.

The rate of unsafe abortions in Kenya has increased from 32 per 1000 women of reproductive age in 2002 to 48 per 1000 women in 2012. This is one of the highest in Sub-Saharan Africa. In 2010, Kenya changed its Constitution to include a more enabling provision regarding the provision of abortion services. Abortion-related stigma has been identified as a key driver in silencing women's ability to reproductive choice leading to seeking to unsafe abortion. We sought to explore abortion-related stigma at the community level as a barrier to women realizing their rights to a safe, legal abortion and compare manifestations of abortion stigma at two communities from regions with high and low incidence of unsafe abortion. A qualitative study using 26 focus group discussions with general community members in Machakos and Trans Nzoia Counties. We used thematic and content analysis to analyze and compare community member's responses regarding abortion-related stigma. Although abortion is recognized as being very common within communities, community members expressed various ways that stigmatize women seeking an abortion. This included being labeled as killers and are perceived to be a bad influence for women especially young women. Women reported that they were poorly treated by health providers in health facilities for seeking abortion especially young unmarried women. Institutionalization of stigma especially when Ministry of Health withdrew of standards and guidelines only heightened how stigma presents at the facilities and drives women seeking an abortion to traditional birth attendants who offer unsafe abortions leading to increased morbidity and mortality as a result of abortion-related complications. Community members located in counties in regions with high incidence of unsafe abortion also reported higher levels of how they would stigmatize a woman seeking an abortion compared to community members from counties in low incidence region. Young unmarried women bore the

Since the legalization of abortion services in the United States, provision of abortions has remained a controversial issue of high political interest. Routine abortion training is not offered at all obstetrics and gynecology (Ob-Gyn) training programs, despite a specific training requirement by the Accreditation Council for Graduate Medical Education. Previous studies that described Ob-Gyn programs with routine abortion training either examined associations by using national surveys of program directors or described the experience of a single program. We set out to identify enablers of and barriers to Ob-Gyn abortion training in the context of a New York City political initiative, in order to better understand how to improve abortion training at other sites. We conducted in-depth qualitative interviews with 22 stakeholders from 7 New York City public hospitals and focus group interviews with 62 current residents at 6 sites. Enablers of abortion training included program location, high-capacity services, faculty commitment to abortion training, external programmatic support, and resident interest. Barriers to abortion training included lack of leadership continuity, leadership conflict, lack of second-trimester abortion services, difficulty obtaining mifepristone, optional rather than routine training, and antiabortion values of hospital personnel. Supportive leadership, faculty commitment, and external programmatic support appear to be key elements for establishing routine abortion training at Ob-Gyn residency training programs.
Development of Flight-Test Performance Estimation Techniques for Small Unmanned Aerial Systems
McCrink, Matthew Henry
This dissertation provides a flight-testing framework for assessing the performance of fixed-wing, small-scale unmanned aerial systems (sUAS) by leveraging sub-system models of components unique to these vehicles. The development of the sub-system models, and their links to broader impacts on sUAS performance, is the key contribution of this work. The sub-system modeling and analysis focuses on the vehicle's propulsion, navigation and guidance, and airframe components. Quantification of the uncertainty in the vehicle's power available and control states is essential for assessing the validity of both the methods and results obtained from flight-tests. Therefore, detailed propulsion and navigation system analyses are presented to validate the flight testing methodology. Propulsion system analysis required the development of an analytic model of the propeller in order to predict the power available over a range of flight conditions. The model is based on the blade element momentum (BEM) method. Additional corrections are added to the basic model in order to capture the Reynolds-dependent scale effects unique to sUAS. The model was experimentally validated using a ground based testing apparatus. The BEM predictions and experimental analysis allow for a parameterized model relating the electrical power, measurable during flight, to the power available required for vehicle performance analysis. Navigation system details are presented with a specific focus on the sensors used for state estimation, and the resulting uncertainty in vehicle state. Uncertainty quantification is provided by detailed calibration techniques validated using quasi-static and hardware-in-the-loop (HIL) ground based testing. The HIL methods introduced use a soft real-time flight simulator to provide inertial quality data for assessing overall system performance. Using this tool, the uncertainty in vehicle state estimation based on a range of sensors, and vehicle operational environments is
Ares I-X Flight Test Validation of Control Design Tools in the Frequency-Domain
Johnson, Matthew; Hannan, Mike; Brandon, Jay; Derry, Stephen

A major motivation of the Ares I-X flight test program was to Design for Data, in order to maximize the usefulness of the data recorded in support of Ares I modeling and validation of design and analysis tools. The Design for Data effort was intended to enable good post-flight characterizations of the flight control system, the vehicle structural dynamics, and also the aerodynamic characteristics of the vehicle. To extract the necessary data from the system during flight, a set of small predetermined Programmed Test Inputs (PTIs) was injected directly into the TVC signal. These PTIs were designed to excite the necessary vehicle dynamics while exhibiting a minimal impact on loads. The method is similar to common approaches in aircraft flight test programs, but with unique launch vehicle challenges due to rapidly changing states, short duration of flight, a tight flight envelope, and an inability to repeat any test. This paper documents the validation effort of the stability analysis tools to the flight data which was performed by comparing the post-flight calculated frequency response of the vehicle to the frequency response calculated by the stability analysis tools used to design and analyze the preflight models during the control design effort. The comparison between flight day frequency response and stability tool analysis for flight of the simulated vehicle shows good agreement and provides a high level of confidence in the stability analysis tools for use in any future program. This is true for both a nominal model as well as for dispersed analysis, which shows that the flight day frequency response is enveloped by the vehicle s preflight uncertainty models.
Attitudes of medical students to induced abortion.
Buga, G A B
2002-05-01
Unsafe abortion causes 13% of maternal deaths worldwide. Safe abortion can only be offered under conditions where legislation has been passed for legal termination of unwanted pregnancy. Where such legislation exists, accessibility of safe abortion depends on the attitudes of doctors and other healthcare workers to induced abortion. Medical students as future doctors may have attitudes to abortion that will affect the provision of safe abortion. Little is known about the attitudes of South African medical students to abortion. To assess sexual practices and attitudes of medical students to induced abortion and to determine some of the factors that may influence these attitudes. A cross-sectional analytic study involving the self-administration of an anonymous questionnaire. The questionnaire was administered to medical students at a small, but growing, medical school situated in rural South Africa. Demographic data, sexual practices and attitudes to induced abortion. Two hundred and forty seven out of 300 (82.3%) medical students responded. Their mean age was 21.81 +/- 3.36 (SD) years, and 78.8% were Christians, 17.1% Hindus and 2.6% Muslims. Although 95% of the respondents were single, 68.6% were already sexually experienced, and their mean age at coitarche was 17.24+/-3.14 (SD) years. Although overall 61.2% of the respondents felt abortion is murder either at conception or later, the majority (87.2%) would perform or refer a woman for abortion under certain circumstances. These circumstances, in descending order of frequency, include: threat to mother's life (74.1%), in case of rape (62.3%), the baby is severely malformed (59.5%), threat to mother's mental health (53.8%) and parental incompetence (21.0%). Only 12.5% of respondents would perform or refer for abortion on demand, 12.8% would neither perform nor refer for abortion under any circumstances. Religious affiliation and service attendance significantly influenced some of these attitudes and beliefs

[Abortion: towards worldwide legalization].
1998-09-01
A table showing the current status of abortion in the world based on two recent and detailed studies is presented. Countries are categorized according to whether they totally prohibit abortion, permit it to save the mother's life, permit it to preserve her physical health or mental health, permit it for maternal socioeconomic reasons, or provide it at the mother's request. The countries are grouped into 5 geographic areas: America and the Caribbean; Central Asia, Middle East, and North Africa; East and South Asia and the Pacific; Europe; sub-Saharan Africa. The trend toward liberalization of laws is clear. The development of abortion laws is moving in the direction of complete legalization, that is, the creation of health norms that facilitate abortion for all women, with guarantees of medical safety. There are still countries that move to restrict access to abortion, and in a few cases, such as Colombia and Poland, legalization and prohibition have alternated depending on the social and political circumstances of the moment. In the past 12 years, 28 countries liberalized their laws in some way, while 4 countries with close ties to the Vatican restricted or prohibited access.
Mental health and abortion: review and analysis.
Ney, P G; Wickett, A R
1989-11-01
This survey of studies which relate to the emotional sequelae of induced abortion, draws attention to the need for more long-term, in-depth prospective studies. The literature to this point finds no psychiatric indications for abortion, and no satisfactory evidence that abortion improves the psychological state of those not mentally ill; abortion is contra-indicated when psychiatric disease is present, as mental ill-health has been shown to be worsened by abortion. Recent studies are turning up an alarming rate of post-abortion complications such as P.I.D., and subsequent infertility. The emotional impact of these complications needs to be studied. Other considerations looked at are the long-term demographic implications of abortion on demand and the effect on the medical professions.

A multi-engine aircraft, with some or all of the flight control system inoperative, may use engine thrust for control. NASA Dryden has conducted a study of the capability and techniques for this emergency flight control method for the F-15 airplane. With an augmented control system, engine thrust, along with appropriate feedback parameters, is used to control flightpath and bank angle. Extensive simulation studies have been followed by flight tests. This paper discusses the principles of throttles-only control, the F-15 airplane, the augmented system, and the flight results including landing approaches with throttles-only control to within 10 ft of the ground.
A measured response: Koop on abortion.
Koop, C E
1989-01-01
The available scientific literature on the health effects of abortion on women in the US neither supports nor refutes the premise that abortion contributes to psychological problems. The 250 studies that have considered the psychological aspects of abortion are all flawed methodologically. Needed to resolve this issue is a prospective study of a cohort of US women of childbearing age focused on the psychological effects of failure to conceive, as well as the physical and mental sequelae of pregnancy whether carried to delivery, miscarried, or terminated by abortion. The most desirable such study could be conducted for about US$100 million over a 5-year period; a less expensive yet satisfactory study could be conducted for $10 million over the same time frame. Before such a study can be undertaken, a survey instrument must be designed to eliminate the discrepancy between the number of abortions on record and the number of women who admit to having an abortion on survey. Another issue is that the health effects of abortion cannot easily be separated from the controversial social issues surrounding pregnancy termination.

To describe both shedding and serological patterns following abortions detected as being associated with Coxiella burnetii (Cb), 24 cows experiencing an abortion due to Cb were followed over a one month period. Samples taken on the day of abortion (D0) were followed 3-fold by weekly samplings from day 14 (D14) to D28 after the abortion. Milk and vaginal mucus were collected at each weekly sampling and tested using real-time PCR while blood samples were collected 2-fold on D21 and D28 and tested using ELISA. We found a very short duration of C. burnetii shedding in vaginal mucus after abortion, highlighting the need to collect samples as rapidly as possible following an abortion to avoid false negative results. In contrast with previous results, concomitancy of vaginal and mucus shedding was frequent, especially for cows shedding a high bacterial load on DO leading to the hypothesis that the clinical onset of the infection influences the modalities of Cb shedding. Lastly, serological results indicating a lack of sensitivity to detect Cb shedder cows (especially for cows for which Ct values were high) suggest that ELISA is not a useful tool to diagnose abortions at the individual level.

Outcome of pregnancy complicated by threatened abortion.
Dongol, A; Mool, S; Tiwari, P
2011-01-01
Threatened abortion is the most common complication in the first half of pregnancy. Most of these pregnancies continue to term with or without treatment. Spontaneous abortion occurs in less than 30% of these women. Threatened abortion had been shown to be associated with increased incidence of antepartum haemorrhage, preterm labour and intra uterine growth retardation. This study was to asses the outcome of threatened abortion following treatment. This prospective study was carried out in Dhulikhel Hospital - Kathmandu University Hospital from January 2009 till May 2010. Total 70 cases of threatened abortion were selected, managed with complete bed rest till 48 hrs of cessation of bleeding, folic acid supplementation, uterine sedative, and hormonal treatment till 28 weeks of gestation. Ultrasonogram was performed for diagnosis and to detect the presence of subchorionic hematoma. Patients were followed up until spontaneous abortion or up to delivery of the fetus. The measures used for the analysis were maternal age, parity, gestational age at the time of presentation, previous abortions, presence of subchorionic hematoma, complete abortion, continuation of pregnancy, antepartum hemorrhage, intrauterine growth retardation and intrauterine death of fetus. Out of 70 cases subchorionic haematoma was found in 30 (42.9%) cases. There were 12 (17.1%) patients who spontaneously aborted after diagnosis of threatened abortion during hospital stay, 5 (7.1%) aborted on subsequent visits while 53 (75.8%) continued pregnancy till term. Among those who continued pregnancy intrauterine growth retardation was seen in 7 (13.2%), antepartum hemorrhage in 4 (7.5%), preterm premature rupture of membrane in 3 (5.66%) and IUD in 3 (5.66%). Spontaneous abortion was found more in cases with subchorionic hematoma of size more than 20 cm2. In cases of threatened abortion with or without the presence of subchorionic hematoma, prognostic outcome is better following treatment with bed rest
Factors associated with repeat induced abortion in Kenya.

Over six million induced abortions were reported in Africa in 2008 with over two million induced abortions occurring in Eastern Africa. Although a significant proportion of women in the region procure more than one abortion during their reproductive period, there is a dearth of research on factors associated with repeat abortion. Data for this study come from the Magnitude and Incidence of Unsafe Abortion Study conducted by the African Population and Health Research Center in Kenya in 2012. The study used a nationally-representative sample of 350 facilities (level II to level VI) that offer post-abortion services for complications following induced and spontaneous abortions. A prospective morbidity survey tool was used by health providers in 328 facilities to collect information on socio-demographic charateristics, reproductive health history and contraceptive use at conception for all patients presenting for post-abortion services. Our analysis is based on data recorded on 769 women who were classified as having had an induced abortion. About 16 % of women seeking post abortion services for an induced abortion reported to have had a previous induced abortion. Being separated or divorced or widowed, having no education, having unwanted pregnancy, having 1-2 prior births and using traditional methods of contraception were associated with a higher likelihood of a repeat induced abortion. The findings point to the need to address the reasons why women with first time induced abortion do not have the necessary information to prevent unintended pregnancies and further induced abortions. Possible explanations linked to the quality of post-abortion family planning and coverage of long-acting methods should be explored.
Induced abortion in Italy: levels, trends and characteristics.
Bettarini, S S; D'Andrea, S S
1996-01-01
Subsequent to the legalization of abortion in Italy in 1978, abortion; rates among Italian women first rose and then declined steadily, from a peak of 16.9 abortions per 1,000 women of reproductive age in 1983 to 9.8 per 1,000 in 1993. Abortion rates vary considerably by geographic region, with rates typically highest in the more secular and modernized regions and lowest in regions where traditional values predominate. Data from 1981 and 1991 indicate that age-specific abortion rates decreased during the 1980s for all age-groups, with the largest declines occurring in regions with the highest levels of abortion. Moreover, a shift in the age distribution of abortion rates occurred during the 1980s, with women aged 30-34 registering the highest abortion rate in 1991, whereas in 1981 the highest level of abortion occurred among those aged 25-29. The abortion rate among adolescent women was low at both times (7.6 per 1,000 in 1981 and 4.6 per 1,000 in 1991). These data are based only on reported legal abortions; the number of clandestine abortions remains unknown.
Dangertalk: Voices of abortion providers.
Martin, Lisa A; Hassinger, Jane A; Debbink, Michelle; Harris, Lisa H
2017-07-01
Researchers have described the difficulties of doing abortion work, including the psychosocial costs to individual providers. Some have discussed the self-censorship in which providers engage in to protect themselves and the pro-choice movement. However, few have examined the costs of this self-censorship to public discourse and social movements in the US. Using qualitative data collected during abortion providers' discussions of their work, we explore the tensions between their narratives and pro-choice discourse, and examine the types of stories that are routinely silenced - narratives we name "dangertalk". Using these data, we theorize about the ways in which giving voice to these tensions might transform current abortion discourse by disrupting false dichotomies and better reflecting the complex realities of abortion. We present a conceptual model for dangertalk in abortion discourse, connecting it to functions of dangertalk in social movements more broadly. Copyright © 2017 Elsevier Ltd. All rights reserved.
Abortion and the pregnant teenager
Lipper, Irene; Cvejic, Helen; Benjamin, Peter; Kinch, Robert A.
1973-01-01
A study was carried out at the Adolescent Unit of The Montreal Children's Hospital from September 1970 to December 1972, the focus of which evolved from the pregnant teenager in general to the short- and long-term effects of her abortion. Answers to a questionnaire administered to 65 pregnant girls to determine the psychosocial characteristics of the pregnant teenager indicated that these girls are not socially or emotionally abnormal. A follow-up study of 50 girls who had an abortion determined that the girls do not change their life styles or become emotionally unstable up to one year post-abortion, although most have a mild, normal reaction to the crisis. During the study period the clinic services evolved from mainly prenatal care to mainly abortion counselling, and then to providing the abortion with less counselling, placing emphasis on those cases which require other than medical services.

Test Hardware Design for Flight-Like Operation of Advanced Stirling Convertors
Oriti, Salvatore M.
2012-01-01
NASA Glenn Research Center (GRC) has been supporting development of the Advanced Stirling Radioisotope Generator (ASRG) since 2006. A key element of the ASRG project is providing life, reliability, and performance testing of the Advanced Stirling Convertor (ASC). For this purpose, the Thermal Energy Conversion branch at GRC has been conducting extended operation of a multitude of free-piston Stirling convertors. The goal of this effort is to generate long-term performance data (tens of thousands of hours) simultaneously on multiple units to build a life and reliability database. The test hardware for operation of these convertors was designed to permit in-air investigative testing, such as performance mapping over a range of environmental conditions. With this, there was no requirement to accurately emulate the flight hardware. For the upcoming ASC-E3 units, the decision has been made to assemble the convertors into a flight-like configuration. This means the convertors will be arranged in the dual-opposed configuration in a housing that represents the fit, form, and thermal function of the ASRG. The goal of this effort is to enable system level tests that could not be performed with the traditional test hardware at GRC. This offers the opportunity to perform these system-level tests much earlier in the ASRG flight development, as they would normally not be performed until fabrication of the qualification unit. This paper discusses the requirements, process, and results of this flight-like hardware design activity.
Abortion and compelled physician speech.
Orentlicher, David
2015-01-01
Informed consent mandates for abortion providers may infringe the First Amendment's freedom of speech. On the other hand, they may reinforce the physician's duty to obtain informed consent. Courts can promote both doctrines by ensuring that compelled physician speech pertains to medical facts about abortion rather than abortion ideology and that compelled speech is truthful and not misleading. © 2015 American Society of Law, Medicine & Ethics, Inc.

Unintended Pregnancy, Induced Abortion, and Mental Health.
Horvath, Sarah; Schreiber, Courtney A
2017-09-14
The early medical literature on mental health outcomes following abortion is fraught with methodological flaws that can improperly influence clinical practice. Our goal is to review the current medical literature on depression and other mental health outcomes for women obtaining abortions. The Turnaway Study prospectively enrolled 956 women seeking abortion in the USA and followed their mental health outcomes for 5 years. The control group was comprised of women denied abortions based on gestational age limits, thereby circumventing the major methodological flaw that had plagued earlier studies on the topic. Rates of depression are not significantly different between women obtaining abortion and those denied abortion. Rates of anxiety are initially higher in women denied abortion care. Counseling on decision-making for women with unintended pregnancies should reflect these findings.
Post legalisation challenge: minimizing complications of abortion.
Ojha, N; Sharma, S; Paudel, J
2004-01-01
Abortion has been legalized in Nepal since September 2002 by 11th amendment to the Muluki Ain. The present study was conducted in Paropakar Shree Panch Indra Rajya Laxmi Devi Maternity Hospital to assess the magnitude of induced abortion, its causes and the types of complications, in the post legalization phase. Prospective descriptive analyses of the patients who were admitted with history of induced abortion from 16th Dec 2003 to 13th March 2004 was carried out. A total of 305 cases of abortion complications were admitted during the three-month study period, which is 39.7% of the total gynaecological admissions (768). Of these 31 (10.25%) patients had history of induced abortion. Half of the induced abortion cases (52%) were of age group 21-29 yrs and 42% had three or more children. 39% of the cases had history of induced abortion at more than 12 weeks and almost half of the cases (48%) had history of family planning. The most common reason for seeking abortion was too many children (59%) followed by illegitimate pregnancy (16%). Twenty-one patients gave history of abortion being performed by doctors and the most common method used was D and C (75%). 77% of cases presented as incomplete abortion and one case presented with uterine perforation, bowel injury and peritonitis. Twenty patients had evacuation under sedation while five had manual vacuum aspiration (MVA); one patient required laparatomy. In two third of the patients intravenous fluid and antibiotics were used. Four patients required blood transfusion. Abortion complications constitute almost 40% of the total gynaecological admissions. Ten percent of the abortion cases had history of induced abortion. Medical persons, mainly doctors, performed most of the cases of induced abortion and D and C was the most commonly used method. However the patients had faced various types of complications. Untrained provider, resulting in serious life threatening injuries, performed more than a third of the cases of
Women's attitudes to safe-induced abortion in Iran: Findings from a pilot survey.

To explore attitudes to safe-induced abortion among pregnant women in Iran. In Islamic teachings, abortion is generally forbidden. However in specific circumstances, abortion may be permitted and currently, in Iran, the law allows termination of pregnancy only if three specialist physicians confirm that the pregnancy outcome may be harmful for the mother during pregnancy or after birth. Pilot, descriptive survey. A 15-item structured questionnaire focusing on attitudes to safe-induced abortion was developed and pilot tested. Participants were pregnant women who were referred to the Legal Medical Centre (July-December 2015) to obtain permission for abortion. On obtaining their informed consent, the women were asked to respond to each item if they agreed (Yes) or disagreed (No). Only their age, education, employment, marital status and religion were obtained. Of the 80 survey participants referred for a safe-induced abortion, 90% were carrying foetuses with a diagnosed congenital malformation and 10% were experiencing complications of pregnancy that endangered their health. The majority of women (85%) perceived abortion to be dangerous to health; 86% indicated that partners should be involved in decision-making about abortion, while 83% believed that public health officials should have complete control of abortion law. There is a need to improve women's and couples' awareness and practice of effective contraceptive methods. Further research is needed to better understand the complex issues that lead to unintended pregnancies and abortions considering religious beliefs and cultural and legal contexts. © 2017 John Wiley & Sons Ltd.
Prolonged grieving after abortion: a descriptive study.
Brown, D; Elkins, T E; Larson, D B
1993-01-01
Although flawed by methodological problems, the research literature tends to provide support for the assumption that induced abortion in the 1st trimester is not accompanied by enduring negative psychological sequelae. In cases where such sequelae are reported, the morbidity is attributed to a pre-existing psychiatric condition or circumstances precipitating the choice of abortion. However, detailed descriptive letters from 45 women prepared in response to a request by a pastor of an upper-middle-class Protestant congregation in Florida indicate that prolonged grieving after abortion may be more widespread phenomenon than previously believed. Letter writers ranged in age from 25-60 years; 75% were unmarried at the time of the procedure and 29% aborted before the legalization of abortion in the US. The most frequently cited long-term sequela, especially among those who felt coerced to abort, was a continued feeling of guilt. Fantasies about the aborted fetus was the next most frequently mentioned experience. Half of the letter writers referred to their abortions, as "murder" and 44% voiced regret about their decision to abort. Other long-term effects included depression (44%), feelings of loss (31%), shame (27%), and phobic responses to infants (13%). For 42% of these women, the adverse psychological effects of abortion endured over 10 years. Since letter-writers came from a self-selected population group with a known bias against abortion and only negative experiences were solicited, these experiences must be regarded as subjectives and anecdotal. However, they draw attention to the need for methodologically sound studies of a possible prolonged grief syndrome among a small percentage of women who have abortions, especially when coercion is involved.
Women's existential experiences within Swedish abortion care.
Stålhandske, Maria L; Ekstrand, Maria; Tydén, Tanja
2011-03-01
To explore Swedish women's experiences of clinical abortion care in relation to their need for existential support. Individual in-depth interviews with 24 women with previous experience of unwanted pregnancy and abortion. Participants were recruited between 2006 and 2009. Interviews were analysed by latent content analysis. Although the women had similar experiences of the abortion care offered, the needs they expressed differed. Swedish abortion care was described as rational and neutral, with physical issues dominating over existential ones. For some women, the medical procedures triggered existential experiences of life, meaning, and morality. While some women abstained from any form of existential support, others expressed a need to reflect upon the existential aspects and/or to reconcile their decision emotionally. As women's needs for existential support in relation to abortion vary, women can be disappointed with the personnel's ability to respond to their thoughts and feelings related to the abortion. To ensure abortion care personnel meet the physical, psychological and existential needs of each patient, better resources and new lines of education are needed to ensure abortion personnel are equipped to deal with the existential aspects of abortion care.

Chlamydia pecorum: fetal and placental lesions in sporadic caprine abortion.
Giannitti, Federico; Anderson, Mark; Miller, Myrna; Rowe, Joan; Sverlow, Karen; Vasquez, Marce; Cantón, Germán
2016-03-01
Chlamydial abortion in small ruminants is usually associated with Chlamydia abortus infection. Although Chlamydia pecorum has been detected in aborted ruminants and epidemiological data suggests that C. pecorum is abortigenic in these species, published descriptions of lesions in fetuses are lacking. This work describes fetoplacental lesions in a caprine abortion with C. pecorum infection, and further supports the abortigenic role of C. pecorum in ruminants. A 16-month-old Boer goat aborted twin fetuses at ~130 days of gestation. Both fetuses (A and B) and the placenta of fetus A were submitted for postmortem examination and diagnostic workup. At autopsy, the fetuses had moderate anasarca, intermuscular edema in the hindquarters (A), and brachygnathia and palatoschisis (B). In the placenta, the cotyledons were covered by yellow fibrinosuppurative exudate that extended into the adjacent intercotyledonary areas. Histologically, there was severe suppurative and necrotizing placentitis with vasculitis (arteriolitis) and thrombosis, multifocal lymphohistiocytic and neutrophilic hepatitis (A), and fibrinosuppurative enteritis in both fetuses. Chlamydia antigen was detected in the placenta by the direct fluorescent antibody test and in fetal intestines by immunohistochemistry. Nested polymerase chain reaction of DNA extracted from formalin-fixed, paraffin-embedded sections of placenta and intestine amplified 400 bp of the Chlamydia 16S rRNA gene that was sequenced and found to be 99% identical to C. pecorum by BLAST analysis. Other known abortigenic infectious agents were ruled out by specific testing. It is concluded that C. pecorum infection is associated with fetoplacental lesions and sporadic abortion in goats. © 2015 The Author(s).
Towards safe abortion access: an exploratory study of medical abortion in Cambodia.
Petitet, Pascale Hancart; Ith, Leakhena; Cockroft, Melissa; Delvaux, Thérèse
2015-02-01
In 2010, following its approval by the Ministry of Health, the medical abortion combination pack Medabon (containing mifepristone and misoprostol) was made available at pharmacies and in a restricted number of health facilities in Cambodia. The qualitative study presented in this paper was conducted in 2012 as a follow-up to longer-term ethnographical research related to reproductive health and fertility regulation between 2008 and 2012. Observations were carried out at several clinic and pharmacy sites and in-depth interviews were conducted with a purposive sample of 20 women who attended two MSI Cambodia centres and 10 women identified through social networks; six men (women's male partners); eight health care providers at the two MSI centres and four pill sellers at private or informal pharmacies (who also provided health care services in private clinics). Although the level of training among the drug sellers and providers varied, their knowledge about medical abortion regimens, correct usage and common side effects was good. Overall, women were satisfied with the services provided. Medical abortion was not always a women-only process in this study as some male partners were also involved in the care process. The study illustrates positive steps forward being taken in making abortion safe and preventing and reducing unsafe abortion practices in Cambodia. Copyright © 2015 Reproductive Health Matters.

The decision to seek an abortion is never easy. Women have different reasons for choosing an abortion and their social, economic and religious background may influence how they cope. Furthermore, once pregnant, the alternatives of childbirth and adoption or keeping the baby may not be psychologically neutral. Research studies in this area have been hampered by methodological problems, but most of the better-quality studies have shown no increased risk of mental health problems in women having an abortion. A consistent finding has been that of pre-existing mental illness and subsequent mental health problems after either abortion or childbirth. Furthermore, studies have shown that only a minority of women experience any lasting sadness or regret. Risk factors for this include ambivalence about the decision, level of social support and whether or not the pregnancy was originally intended. More robust, definitive research studies are required on mental health after abortion and alternative outcomes such as childbirth. Copyright 2010 Elsevier Ltd. All rights reserved.
Unmet/met need for contraception and self-reported abortion in Ghana.
Amo-Adjei, Joshua; Darteh, Eugene K M
2017-10-01
Unmet need for contraception in several sub-Saharan African countries, including Ghana, remains high, with implications for unintended pregnancies and unsafe abortion, associated maternal morbidity and mortality. In this paper, we analysed for any associations between unmet/met need for contraception and the prevalence of abortion. The paper utilizes the 2014 Ghana Demographic Health Survey dataset. Applying descriptive statistics initially, and later, a binary logistic regression, we estimate two different models, taking into account, unmet/met need for contraception (Model 1) and a multivariable one comprising socioeconomic, spatial, cultural and demographic behaviour variables (Model 2) to test the associations between unmet/met need for contraception in Ghana. One-fourth (25%) of sampled women in 2014 had ever had an abortion. The bivariate results showed that women who reported "no unmet" considerably tended to report abortion more than the reference category - not married and no sex in the last 30days. The elevated odds among respondents who indicated "no unmet need" persisted even after controlling for all the relevant confounders. Relatedly, unlike women with an unmet need for spacing, women who desired to limit childbearing had a slightly higher tendency to report an abortion. The linkage between unmet need for contraception appears more complex, particularly when the connections are explored post-abortion. Thus, while an abortion episode is most likely due to unintended pregnancy, contraception may still not be used, after an abortion, probably because of failure, side effects or simply, a dislike for any method.

In Jewish law right and wrong, good and evil, are absolute values which transcend time, place, and environment. They defy definition by human intuition or expediency. Jewish law derives from the Divine revelation at Mount Sinai as expounded by sages faithful to, and authorized by, its writ. The Talmud rules that if a woman is in hard travail, and her life must be saved, the child must be aborted and extracted. The mother's life comes first. The fetus is not a human life until it is born. But 19th century Rabbinical works state that it is immoral to destroy a monster child. Modern rabbis are unanimous in condemning abortion, feticide, or infanticide as an unconscionable attack on human life. However, Jewish law allows abortion if the pregnancy will cause severe psychological damage to the mother. No civilized society could survive without laws which occasionally cause some suffering or personal anguish. One human life is worth a million lives, because each life is infinite in value. In cases of rape or incest Jewish law still does not sanction abortion. Man's procreative responsibilities are serious and carry rights and obligations which would be upset by liberalized abortion laws. If a person kills a person who is mortally wounded, the killer is guilty of a moral offense.
Defining minors' abortion rights.
Rhodes, A M
1988-01-01
The right to abortion is confirmed in the Roe versus Wade case, by the US Supreme Court. It is a fundamental right of privacy but not an absolute right, and must consider state interests. During the first trimester of pregnancy abortion is a decision of the woman and her doctor. During the second trimester of pregnancy the state may control the abortion practice to protect the mothers health, and in the last trimester, it may prohibit abortion, except in cases where the mother's life or health are in danger. The states enacted laws, including one that required parents to give written consent for a unmarried minor's abortion. This law was struck down by the US Court, but laws on notification were upheld as long as there was alternative procedures where the minor's interests are upheld. Many of these law have been challenged successfully, where the minor was judged mature and where it served her best interests. The state must enact laws on parental notification that take into consideration basic rights of the minor woman. Health professionals and workers should be aware of these laws and should encourage the minor to let parents in on the decision making process where possible.
Theorizing Time in Abortion Law and Human Rights.
Erdman, Joanna N
2017-06-01
The legal regulation of abortion by gestational age, or length of pregnancy, is a relatively undertheorized dimension of abortion and human rights. Yet struggles over time in abortion law, and its competing representations and meanings, are ultimately struggles over ethical and political values, authority and power, the very stakes that human rights on abortion engage. This article focuses on three struggles over time in abortion and human rights law: those related to morality, health, and justice. With respect to morality, the article concludes that collective faith and trust should be placed in the moral judgment of those most affected by the passage of time in pregnancy and by later abortion-pregnant women. With respect to health, abortion law as health regulation should be evidence-based to counter the stigma of later abortion, which leads to overregulation and access barriers. With respect to justice, in recognizing that there will always be a need for abortion services later in pregnancy, such services should be safe, legal, and accessible without hardship or risk. At the same time, justice must address the structural conditions of women's capacity to make timely decisions about abortion, and to access abortion services early in pregnancy.

Management Process of a Frequency Response Flight Test for Rotorcraft Flying Qualities Evaluation
Directory of Open Access Journals (Sweden)
João Otávio Falcão Arantes Filho
2016-07-01
Full Text Available This paper applies the frequency response methodology to characterize and analyze the flying qualities of longitudinal and lateral axes of a rotary-wing aircraft, AS355-F2. Using the results, it is possible to check the suitability of the aircraft in accordance with ADS-33E-PRF standard, whose flying qualities specifications criteria are based on parameters in the frequency domain. The key steps addressed in the study involve getting, by means of flight test data, the closed-loop dynamic responses including the design of the instrumentation and specification of the sensors to be used in the flight test campaign, the definition of the appropriate maneuvers characteristics for excitation of the aircraft, the planning and execution of the flight test to collect the data, and the proper data treatment, processing and analysis after the flight. After treatment of the collected data, single input-single output spectral analysis is performed. The results permit the analysis of the flying qualities characteristics, anticipation of the demands to which the pilot will be subjected during closed-loop evaluations and check of compliance with the aforementioned standard, within the range of consistent excitation frequencies for flight tests, setting the agility level of the test aircraft.
Abortion and mental health: Evaluating the evidence.
Major, Brenda; Appelbaum, Mark; Beckman, Linda; Dutton, Mary Ann; Russo, Nancy Felipe; West, Carolyn
2009-12-01
The authors evaluated empirical research addressing the relationship between induced abortion and women's mental health. Two issues were addressed: (a) the relative risks associated with abortion compared with the risks associated with its alternatives and (b) sources of variability in women's responses following abortion. This article reflects and updates the report of the American Psychological Association Task Force on Mental Health and Abortion (2008). Major methodological problems pervaded most of the research reviewed. The most rigorous studies indicated that within the United States, the relative risk of mental health problems among adult women who have a single, legal, first-trimester abortion of an unwanted pregnancy is no greater than the risk among women who deliver an unwanted pregnancy. Evidence did not support the claim that observed associations between abortion and mental health problems are caused by abortion per se as opposed to other preexisting and co-occurring risk factors. Most adult women who terminate a pregnancy do not experience mental health problems. Some women do, however. It is important that women's varied experiences of abortion be recognized, validated, and understood. 2009 APA.
Opposition to legal abortion: challenges and questions.
Kissling, F
1993-01-01
An analysis of the Roman Catholic Church's arguments against abortion rights suggests that its opposition is grounded more in outmoded views regarding women's roles than in concern for protecting fetal life. The 1st argument raised by Catholics and other anti-abortion forces is that abortion represents the unjustifiable destruction of a human life. A 2nd argument focuses on the status of the fetus as a person from the moment of conception, making abortion murder. A 3rd equates the fetus's potential for personhood with the pregnant woman's actual personhood. Despite the vehement sentiments expressed by Catholic leaders against abortion, the majority of Catholics support legal abortion. The assignment of personhood status to the fetus is contraindicated by actual practice in the Church, where aborted or miscarried products of early pregnancy are not baptized. Also, the Church does not forbid the taking of human life in war or to preserve political freedom. Finally, in countries such as Poland where abortion has been made illegal through religious pressure, there have been drastic cuts in health care and child care programs.

Configuration management issues and objectives for a real-time research flight test support facility
Yergensen, Stephen; Rhea, Donald C.
1988-01-01
Presented are some of the critical issues and objectives pertaining to configuration management for the NASA Western Aeronautical Test Range (WATR) of Ames Research Center. The primary mission of the WATR is to provide a capability for the conduct of aeronautical research flight test through real-time processing and display, tracking, and communications systems. In providing this capability, the WATR must maintain and enforce a configuration management plan which is independent of, but complimentary to, various research flight test project configuration management systems. A primary WATR objective is the continued development of generic research flight test project support capability, wherein the reliability of WATR support provided to all project users is a constant priority. Therefore, the processing of configuration change requests for specific research flight test project requirements must be evaluated within a perspective that maintains this primary objective.
Induced Abortion: a Systematic Review and Meta-analysis.
Dastgiri, Saeed; Yoosefian, Maryam; Garjani, Mehraveh; Kalankesh, Leila R
2017-03-01
Induced abortion accounts for 1 in 8 of approximately 600000 maternal deaths that occur annually worldwide. Induced abortion rate can be considered as one of the indicators for assessing availability of the appropriate reproductive health plans for women and identifying needs for appropriate related health policies and programs. Researchers searched Pubmed, Google Scholar, CINAHL, Embase, PsycINFO, Cochrane, Iranian Scientific Information Database (SID), Iranian biomedical journals (Iranmedex), and Iranian Research Institute of Information and Documentation (Irandoc) between January 2000 and June 2013, which reported induced abortion. Search terms from two categories including abortion and termination of pregnancy were compiled. The search terms were "induced abortion", "illegal abortion", "illegal abortion", "unsafe abortion", and "criminal abortion". The search was also conducted with "induced termination of pregnancy", "illegal termination of pregnancy", "illegal termination of pregnancy", "unsafe termination of pregnancy" and "criminal termination of pregnancy". Meta-analysis was carried out by using OpenMeta software. Induced abortion rates were calculated based on the random effect model. Overall induced abortion rate was obtained 58.1 per 1000 women (95%CI: 55.16-61.04). In continental level, rate of induced abortion was 14 per 1000 women (95%CI: 11-16). Nation-wide and local rates were obtained 67.27 per 1000 women (95% CI: 60.02-74.23) and 148.92 (95% CI: 140.06-157.79) respectively. Induced abortion is a major public health problem that occurs worldwide whether under the legal restriction or freedom, and it remains as reproductive health concern globally. To eliminate the need for induced abortion is at the core of any effort for preventing this issue. Option with the highest priority is to prevent unwanted pregnancies through promoting reproductive health plans for women of reproductive age. In case the prevention strategies fail, universal provision of

Full Text Available This work deals with the relationship between induced abortion and mental health with a special focus on the area of political controversy. This article explores the historical background of the abortion and its legislative implications in Europe with special reference to Bosnia and Herzegovina. This work is based on etnographich, analitical and historical aproaches. It explains abortion in medical terms and analyzes the psychological effects of the abortion. This is a significant and challanging topic for those who find themselves facing the moral dilemma of whether or not to terminate a pregnancy. Problems of controversy are numerous. Is abortion a murder or not? Is fetus a person or not? When it becomes the one if ever till the birth? If abortion is not morally wrong, that doesn't mean that it's right to have an abortion. If abortion is morally wrong, that doesn't mean that it is always impermissible to have an abortion. The comon dilema is whether having an abortion is less wrong than the alternatives. These are some of the questions this paper deals with.
Abortions bring economic pressure to bear on hospitals.
Taravella, S
1989-08-25
The current abortion controversy has serious potential economic consequences for U.S. hospitals, from boycotts and other political actions, but also because of lack of reimbursement for procedures performed on indigent women. An example was given of a threatened boycott of a private hospital in Washington state by evangelical residents and their physicians. Another example of boycott of hospital blood donations was cited. 1078, or 28.7%, of 3752 U.S. hospitals that are equipped to perform abortions do so. 90% of abortions are done by 31% of U.S. hospitals. 90% of these are 1st trimester abortions, costing $200-300. Many employer-sponsored health insurance plans pay for abortions, but Medicaid programs pay for limited numbers of abortions: all abortions for poor women in 13 states, but only those need to save the woman's life in most states. The federal government paid $62,235 for 84 abortions in 13 states in 1988. California and New York have extensive abortion programs for the poor. Hospitals keep a low profile about abortion services, declining to advertise their activity.
Design Challenges Encountered in a Propulsion-Controlled Aircraft Flight Test Program
Maine, Trindel; Burken, John; Burcham, Frank; Schaefer, Peter
1994-01-01
The NASA Dryden Flight Research Center conducted flight tests of a propulsion-controlled aircraft system on an F-15 airplane. This system was designed to explore the feasibility of providing safe emergency landing capability using only the engines to provide flight control in the event of a catastrophic loss of conventional flight controls. Control laws were designed to control the flightpath and bank angle using only commands to the throttles. Although the program was highly successful, this paper highlights some of the challenges associated with using engine thrust as a control effector. These challenges include slow engine response time, poorly modeled nonlinear engine dynamics, unmodeled inlet-airframe interactions, and difficulties with ground effect and gust rejection. Flight and simulation data illustrate these difficulties.
Mars Science Laboratory Flight Software Boot Robustness Testing Project Report
Roth, Brian
2011-01-01
On the surface of Mars, the Mars Science Laboratory will boot up its flight computers every morning, having charged the batteries through the night. This boot process is complicated, critical, and affected by numerous hardware states that can be difficult to test. The hardware test beds do not facilitate testing a long duration of back-to-back unmanned automated tests, and although the software simulation has provided the necessary functionality and fidelity for this boot testing, there has not been support for the full flexibility necessary for this task. Therefore to perform this testing a framework has been build around the software simulation that supports running automated tests loading a variety of starting configurations for software and hardware states. This implementation has been tested against the nominal cases to validate the methodology, and support for configuring off-nominal cases is ongoing. The implication of this testing is that the introduction of input configurations that have yet proved difficult to test may reveal boot scenarios worth higher fidelity investigation, and in other cases increase confidence in the robustness of the flight software boot process.

Most respondents to a survey of abortion patients in 1987 said that more than one factor had contributed to their decision to have an abortion; the mean number of reasons was nearly four. Three-quarters said that having a baby would interfere with work, school or other responsibilities, about two-thirds said they could not afford to have a child and half said they did not want to be a single parent or had relationship problems. A multivariate analysis showed young teenagers to be 32 percent more likely than women 18 or over to say they were not mature enough to raise a child and 19 percent more likely to say their parents wanted them to have an abortion. Unmarried women were 17 percent more likely than currently married women to choose abortion to prevent others from knowing they had had sex or became pregnant. Of women who had an abortion at 16 or more weeks' gestation, 71 percent attributed their delay to not having realized they were pregnant or not having known soon enough the actual gestation of their pregnancy. Almost half were delayed because of trouble in arranging the abortion, usually because they needed time to raise money. One-third did not have an abortion earlier because they were afraid to tell their partner or parents that they were pregnant. A multivariate analysis revealed that respondents under age 18 were 39 percent more likely than older women to have delayed because they were afraid to tell their parents or partner.

Two steps back: Poland's new abortion law.
Nowicka, W
1993-06-01
After the fall of Communism in Poland, the Catholic church exerted pressure to increase its influence in public life. One way in which this pressure has manifested itself has been in the passing of a restrictive abortion bill which was signed into law on February 15, 1993. Abortion had been legalized in Poland in 1956 and was used as a means of birth control because of a lack of availability and use of contraceptives. The number of abortions performed was variously reported as 60,000 - 300,000/year. In 1990, the Ministry of Health imposed restrictions on abortions at publicly funded hospitals, and 3 deaths were reported from self-induced abortions. In 1 year (1989-90), the number of induced abortions at 1 hospital dropped from 71 to 19, while the number of self-induced abortions increased from 48 to 85. Further restrictions were introduced in May 1992 as part of the "Ethical Code for Physicians," which allows abortions only in cases where the mother's life or health is in danger or in cases or rape. This code brought abortions to a halt at publicly funded hospitals and doubled or even tripled the cost of private abortions. Women have been refused abortions in tragic and life=threatening situations since the code was adopted. When an outright anti family planning bill was drafted in November 1992, the Polish citizenry collected 1,300,000 signatures to force a referendum. The referendum was not held, but the bill was defeated. The amended bill which passed allows abortions in publicly funded hospitals only when the mother's life or health is in danger and in cases of rape, incest, or incurable deformity of the fetus. The implications of this law remain unclear, since its language is strange and vague. The reproductive rights of Polish women face a further threat because the Catholic church is working to limit the availability of contraceptive methods which they deem to be "early abortives." On the other side of the issue, the Federation for Women and Planned
Attitudes of Mexican geneticists towards prenatal diagnosis and selective abortion.
Carnevale, A; Lisker, R; Villa, A R; Armendares, S
1998-02-03
Prenatal diagnosis (PD) provides the physician information on whether the unborn fetus has a genetic or chromosomal disorder, and offers patients a new option: selective abortion. In the present study, we analyzed the answers Mexican geneticists provided to a few selected questions from a multinational survey designed by Wertz and Fletcher [1988: Am J Hum Genet 42:592-600]. The selected questions were related to the use of PD, the acceptance of selective abortion, and the self-reported directiveness of counselling following the diagnosis of a fetal anomaly. Our results show that the great majority of Mexican geneticists participating in the study agree with PD when medically indicated, but not on free demand. Specific cases stimulated the group on thinking more than the general statements provided in the survey. Although the majority agreed that PD should be available to all women, when faced with cases of nonmorbid maternal anxiety, paternity testing, and sex selection, the proportion of geneticists willing to perform the test decreased substantially. When counselling patients on a fetal anomaly, the minority would be as unbiased as possible, and this seems to be the tendency in developing countries where counselling, as stated in the respondents' comments, reflects the belief that the goal of genetics is the prevention of or opposition to abortion. Counselling was influenced by the severity of the disorder. The geneticists' personal attitude toward abortion in the same situations was stronger than when counselling others. Analysis of directiveness in counselling for fetal anomaly showed that older geneticists, with more years of experience in medical genetics, were more likely to be neutral. When counselling directively, the group showed an overall direction toward continuing affected pregnancies. However, older geneticists and those with more than 10 years of practice were more likely than their younger counterparts to counsel towards terminating affected

[The gynecologist and the problem of therapeutic abortion].
Pundel, J P
1972-01-01
Most of this essay on the abortion problem in French-speaking western Europe concerns the Sermon of Hippocrates forbidding abortion; the discussion ends with an ethical discussion on abortion codes in a pluralist society. 1st, scholars question whether Hippocrates himself actually wrote the text of the Sermon, or whether his Pythagorean followers did. 2nd, probably abortion in Hippocrates' time was relegated to midwives and lithotomists. The meaning of the quotation "I do not give any abortive remedy" is obscure since in other contexts Hippocrates distinguished between abortive and contraceptive drugs and also abortive instruments. Finally, Hipoocrates specifically recommended abortion, e.g., to avoid pregnancy for prostitutes. Persons in authority, then, should not invoke Hippocrates or any other moral code to deprive a woman of medical abortion, especially in cases of rape, age, and failure of contraception. Divorce, for example, has been legalized in most countries, without forcing anyone to take advantage of it.
Diagnosis of autism, abortion and the ethics of childcare in Yoruba culture.
Fayemi, Ademola Kazeem
2014-01-01
This paper examines the ethics of childcare in Yoruba culture in the contexts of autism and abortion. The traditional Yoruba moral principles of ibikojuibi (equality of humans at birth) and ajowapo (solidarity) have been theoretically developed to establish the personhood of autistic children and provide a justification for not aborting foetuses with autism. Despite these justifications, this paper argues that there is a need for contextual rethinking, which would allow for: (i) prenatal genetic testing, as well as abortion of foetuses with a high risk of the autism mutation, and (ii) early clinical diagnosis and treatment of autistic children in contemporary Yoruba society.
An economic approach to abortion demand.

"This paper uses econometric multiple regression techniques in order to analyze the socioeconomic factors affecting the demand for abortion for the year 1985. A cross-section of the 50 [U.S.] states and Washington D.C. is examined and a household choice theoretical framework is utilized. The results suggest that average price of abortion, disposable personal per capita income, percentage of single women, whether abortions are state funded, unemployment rate, divorce rate, and if the state is located in the far West, are statistically significant factors in the determination of the demand for abortion." excerpt

Unbunched beam is a potentially serious issue in the LHC as it may quench the superconducting magnets during a beam abort. Unbunched particles, either not captured by the RF system at injection or leaking out of the RF bucket, will be removed by using the existing damper kickers to excite resonantly the particles in the abort gap. Following beam simulations, a strategy for cleaning the abort gap at different energies was proposed. The plans for the commissioning of the beam abort gap cleaning are described and first results from the beam commissioning are presented.

The abortion issue in the 1980 elections.
Granberg, D; Burlison, J
1983-01-01
The political opponents of legal abortion achieved considerable gains in the 1980 American elections. A president who was committed to a strong antiabortion position was elected, and antiabortion candidates prevailed in six out of seven Senate races that pitted supporters against opponents of legal abortion and in seven out of nine similar confrontations in the House races. However, it is not clear that abortion was an overriding or decisive factor in determining those outcomes. Democrats and Republicans, Carter voters and Reagan voters did not differ significantly in their attitudes toward abortion. The presidential voter groups were divided on several other issues, and along income and racial lines, to a far greater extent than they were on abortion. Voters were not likely to name abortion as one of the more important problems facing the nation. Carter supporters rated abortion as more important than did Reagan supporters. Although the party platforms and the presidential candidates were clearly differentiated in their abortion stands, these differences were not well communicated to the citizenry. When voters attempted to describe the position of each candidate on abortion, they displayed a great deal of uncertainty, error and confusion. In the key Senate races, those who voted for the prochoice candidates held more liberal abortion attitudes than those who voted for the right-to-life candidates. This difference, although statistically significant, was not great, and was smaller than the differences related to several other issues--such as attitudes toward the role of government, women's rights and economic policies.(ABSTRACT TRUNCATED AT 250 WORDS)
Psychiatric aspects of induced abortion.
Stotland, Nada L
2011-08-01
Approximately one third of the women in the United States have an abortion during their lives. In the year 2008, 1.21 million abortions were performed in the United States (Jones and Koolstra, Perspect Sex Reprod Health 43:41-50, 2011). The psychiatric outcomes of abortion are scientifically well established (Adler et al., Science 248:41-43, 1990). Despite assertions to the contrary, there is no evidence that abortion causes psychiatric problems (Dagg, Am J Psychiatry 148:578-585, 1991). Those studies that report psychiatric sequelae suffer from severe methodological defects (Lagakos, N Engl J Med 354:1667-1669, 2006). Methodologically sound studies have demonstrated that there is a very low incidence of frank psychiatric illness after an abortion; women experience a wide variety of feelings over time, including, for some, transient sadness and grieving. However, the circumstances that lead a woman to terminate a pregnancy, including previous and/or ongoing psychiatric illness, are independently stressful and increase the likelihood of psychiatric illness over the already high baseline incidence and prevalence of mood and anxiety disorders among women of childbearing age. For optimal psychological outcomes, women, including adolescents, need to make autonomous and supported decisions about problem pregnancies. Clinicians can help patients facing these decisions and those who are working through feelings about having had abortions in the past.

Scuffing-like damage has been found on the tooth surfaces of gears 5 and 6 of the NASA space shuttle rudder/speed brake power drive unit (PDU) number 2 after the occurrence of a transient back-driving event in flight. Tests were conducted using a pair of unused spare flight gears in a bench test at operating conditions up to 2866 rpm and 1144 in.-lb at the input ring gear and 14,000 rpm and 234 in.-lb at the output pinion gear, corresponding to a power level of 52 hp. This test condition exceeds the maximum estimated conditions expected in a backdriving event thought to produce the scuffing damage. Some wear marks were produced, but they were much less severe than the scuffing damaged produced during shuttle flight. Failure to produce scuff damage like that found on the shuttle may be due to geometrical variations between the scuffed gears and the gears tested herein, more severe operating conditions during the flight that produced the scuff than estimated, the order of the test procedures, the use of new hydraulic oil, differences between the dynamic response of the flight gearbox and the bench-test gearbox, or a combination of these. This report documents the test gears, apparatus, and procedures, summarizes the test results, and includes a discussion of the findings, conclusions, and recommendations.
Irish women who seek abortions in England.
Francome, C
1992-01-01
In 1991, 4158 women from Ireland and 1766 from Northern Ireland traveled to England for abortions. This situation has been ignored by Irish authorities. The 1992 case of the 14-year old seeking an abortion in England finally caught legal attention. This study attempts to help define who these abortion seekers are. Questionnaires from 200 Irish abortion seeking women attending private Marie Stopes clinics in London and the British Pregnancy Advisory Services clinic in Liverpool between September 1988 and December 1990 were analyzed. Findings pertain to demographic characteristics, characteristics of first intercourse, family discussion of sexual activity, and contraceptive use. From this limited sample, it appears that Irish women are sexually reserved and without access to modern methods of birth control and abortion. Sex is associated with shame and guilt. 23% had intercourse before the age of 18 years and 42% after the age of 20. 76% were single and 16% were currently married. 95% were Catholic; 33% had been to church the preceding Sunday and 68% within the past month. Basic information about menstruation is also limited and procedures such as dilatation and curettage may be performed selectively. 28% of married women were uninformed about menstruation prior to its onset. Only 24% had been using birth control around the time of pregnancy. The reason for nonuse was frequently the unexpectedness of intercourse. 62% of adults and 66% of women believe in legalizing abortion in Ireland. British groups have tried to break through the abortion information ban by sending telephone numbers of abortion clinics to Irish firms for distribution to employees. On November 25, 1992, in the general election, there was approval of constitutional amendments guaranteeing the right to travel for abortions and to receive information on abortion access. The amendment to allow abortion to save the life of the mother was not accepted.
[Role of ultrasound in elective abortions].
Wylomanski, S; Winer, N
2016-12-01
Ultrasound plays a fundamental role in the management of elective abortions. Although it can improve the quality of post-abortion care, it must not be an obstacle to abortion access. We thus studied the role of ultrasound in pregnancy dating and possible alternatives and analyzed the literature to determine the role of ultrasound in post-abortion follow-up. During an ultrasound scan, the date of conception is estimated by measurement of the crown-rump length (CRL), defined by Robinson, or of the biparietal diameter (BPD), as defined by the French Center for Fetal Ultrasound (CFEF) after 11 weeks of gestation (Robinson and CFEF curves) (grade B). Updated curves have been developed in the INTERGROWTH study. In the context of abortion, the literature recommends the application of a safety margin of 5 days, especially when the CRL and/or BPD measurement indicates a term close to 14 weeks (that is equal or below 80 and 27mm, respectively) (best practice agreement). Accordingly, with the ultrasound measurement reliable to±5 days when its performance meets the relevant criteria, an abortion can take place when the CRL measurement is less than 90mm or the BPD less than 30mm (INTERGROWTH curves) (best practice agreement). While a dating ultrasound should be encouraged, its absence is not an obstacle to scheduling an abortion for women who report that they know the date of their last menstrual period and/or of the at-risk sexual relations and for whom a clinical examination by a healthcare professional is possible (best practice agreement). In cases of intrauterine pregnancy of uncertain viability or of a pregnancy of unknown location, without any particular symptoms, the patient must be able to have a transvaginal ultrasound to increase the precision of the diagnosis (grade B). Various reviews of the literature on post-abortion follow-up indicate that the routine use of ultrasound during instrumental abortions should be avoided (best practice agreement). If it becomes
Myths and misconceptions about abortion among marginalized underserved community.
Thapa, K; Karki, Y; Bista, K P
2009-01-01
Unsafe abortion remains a huge problem in Nepal even after legalization of abortion. Various myths and misconceptions persist which prompt women towards unsafe abortive practices. A qualitative study was conducted among different groups of women using focus group discussions and in depth interviews. Perception and understanding of the participants on abortion, methods and place of abortion were evaluated. A number of misconceptions were prevalent like drinking vegetable and herbal juices, and applying hot pot over the abdomen could abort pregnancy. However, many participants also believed that health care providers should be consulted for abortion. Although majority of the women knew that they should seek medical aid for abortion, they were still possessed with various misconceptions. Merely legalizing abortion services is not enough to reduce the burden of unsafe abortion. Focus has to be given on creating awareness and proper advocacy in this issue.

Full Text Available Background & aim: Abortion is the third leading cause of maternal mortality. The attitude of women towards abortion is one of the most important factors involved in this issue. This study aimed to evaluate the attitude of women of reproductive age towards induced abortion. Methods This cross-sectional study was performed on 450 women of reproductive age in Fatemieh Hospital in Hamedan, Iran in 2014. Data was collected using abortion attitude scale consisting of five sections: socioeconomic status, family status, maternal and fetal health status, psycho -cultural background, and fertility status. Mean score less than three in each domain was considered as negative attitude, while scores higher or equal to three indicated positive attitude towards induced abortion. To analyze the data, logistic regression analysis, Chi-square and Fisher's exact tests were performed using SPSS version 21. P value of less than 0.05 was considered statistically significant. Results: In this study, induced abortion had no significant relationship with family status, maternal and fetal health, and fertility domains (82.1%, 77.3%, and 64.4%, respectively. A relationship was observed between induced abortion and socioeconomic and psycho-cultural domains (61.8% and 56%, respectively. Logistic regression analysis showed that the predictors of induced abortion were the attitude towards the effect of abortion on the health of mother and fetus (P= 0.01, as well as the psychocultural status of the mothers (P= 0.02. Conclusion: Evaluation of the results indicated a strong belief in the majority of the participants in psychocultural and socioeconomic domains as the most significant predictive factors for induced abortion. Since it is difficult to alter the socioeconomic and psychocultural domains of individuals, changes are recommended in predominant attitudes towards induced abortion.

Objective To investigate the effects of allograft inflammatory factor-1(AIF-1)and (RANTES) in sera and deciduas on unexplained early spontaneous abortion.Methods AIF-1 and RANTES were examined in sera and deciduas/endometria of 43 unexplained early spontaneous abortion women (group A),40 healthy women with early pregnancy(group B)and 20 healthy women with no pregnancy (group C). Immunohistochemistry and enzyme linked immunosorbent assay (ELISA) were used in this study. Results AIF-1 protein was expressed both in deciduas of group A and in endometria of group C.In group A, H scores in the recurrent abortion deciduas specimens were significantly greater than those in the first abortion;in endometrium,expression of AIF-1 was greater in the secretory than in proliferative phase of group C.In group B,concentrations of RANTES in sera were higher in 7th-8th week of pregnancy than in 6th-7th and >8th week of pregnancy;expression of AIF-1 protein showed a negative correlation with RASNTES concentration;a significant increase of the RANTES levels in sera and tissue was observed in group B. Conclusion These results demonstrate, for the first time,that AIF-1 are expressed in deciduas of unexplained spontaneous abortion suggesting that AIF-1 involve in alloimmune abortion; RANTES might act as a novel blocking antibody;AIF-1 and RANTES might act as reliable markers for diagnosis of early alloimmune abortion.

The Large Hadron Collider (LHC), presently under construction at CERN, requires monitoring the parasitic charge in the 3.3ms long gap in the machine fill structure. This gap, referred to as the abort gap, corresponds to the raise time of the abort kickers magnets. Any circulating particle present in the abort gap at the time of the kickers firing is lost inside the ring, rather than in the beam dump, and can potentially damage a number of the LHC components. CERN specifications indicate a linear density of 6 x 106 protons over a 100 ns interval as the maximum charge safely allowed to accumulate in the abort gap at 7 TeV. We present a study of an abort gap monitor, based on a photomultiplier tube with a gated microchannel plate, which would allow for detecting such low charge densities by monitoring the synchrotron radiation emitted in the dedicated diagnostics port. We show results of beam test experiments at the Advanced Light Source (ALS) using a Hamamatsu 5961U MCP-PMT, which indicate that such an instrument has the required sensitivity to meet LHC specifications
Access to Medication Abortion Among California's Public University Students.
Upadhyay, Ushma D; Cartwright, Alice F; Johns, Nicole E
2018-06-09
A proposed California law will require student health centers at public universities to provide medication abortion. To understand its potential impact, we sought to describe current travel time, costs, and wait times to access care at the nearest abortion facilities. We projected total medication abortion use based on campus enrollment figures and age- and state-adjusted abortion rates. We calculated distance and public transit time from campuses to the nearest abortion facility. We contacted existing abortion-providing facilities to determine costs, insurance acceptance, and wait times. We estimate 322 to 519 California public university students seek medication abortions each month. As many as 62% of students at these universities were more than 30 minutes from the closest abortion facility via public transportation. Average cost of medication abortion was $604, and average wait time to the first available appointment was one week. College students face cost, scheduling, and travel barriers to abortion care. Offering medication abortion on campus could reduce these barriers. Copyright © 2018 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

LISA will be the first space-home gravitational wave observatory. It aims to detect gravitational waves in the 0.1 mHz/1 Hz range from sources including galactic binaries, super-massive black-hole binaries, capture of objects by super-massive black-holes and stochastic background. LISA is an ESA approved Cornerstone Mission foreseen as a joint ESA-NASA endeavour to be launched in 2010-11. The principle of operation of LISA is based on laser ranging of test-masses under pure geodesic motion. Achieving pure geodesic motion at the level requested for LISA, 3x10 -15 ms -2 /√Hz at 0.1 mHz, is considered a challenging technological objective. To reduce the risk, both ESA and NASA are pursuing an in-flight test of the relevant technology. The goal of the test is to demonstrate geodetic motion within one order of magnitude from the LISA performance. ESA has given this test as the primary goal of its technology dedicated mission SMART-2 with a launch in 2006. This paper describes the basics of LISA, its key technologies, and its in-flight precursor test on SMART-2

To estimate the extent to which abortion in dairy cows was associated with of Neospora caninum (N. caninum) and to determine the risk factors of neosporosis in dairy farms from 9 provinces in Iran. Methods: Polymerase chain reaction (PCR) test was used to detect Neospora infection in the brain of 395 bovine aborted fetuses from 9 provinces of Iran. In addition, the brains of aborted fetuses were taken for histopathological examination. To identify the risk factors associated with neosporosis, data analysis was performed by SAS. Results: N. caninum was detected in 179 (45%) out of 395 fetal brain samples of bovine aborted fetuses using PCR. Among the PCR-positive brain samples, only 56 samples were suited for histopathological examination. The characteristic lesions of Neospora infection including non-suppurative encephalitis were found in 16 (28%) of PCR-positive samples. The risk factors including season, parity of dam, history of bovine virus diarrhea and infectious bovine rhinotracheitis infection in herd, cow’s milk production, herd size and fetal appearance did not show association with the infection. This study showed that Neospora caused abortion was significantly more in the second trimester of pregnancy than other periods. In addition, a significant association was observed between Neospora infection and stillbirth. Conclusions: The results showed N. caninum infection was detected in high percentage of aborted fetuses. In addition, at least one fourth of abortions caused by Neospora infection. These results indicate increasing number of abortions associated with the protozoa more than reported before in Iran.

The fill pattern in proton synchrotrons usually features an empty gap, longer than the abort kicker raise time, for machine protection. This gap is referred to as the ''abort gap'' and any particles, which may accumulate in it due to injection errors and diffusion between RF buckets, would be lost inside the ring, rather than in the beam dump, during the kicker firing. In large proton rings, due to the high energies involved, it is vital to monitor the build up of charges in the abort gap with a high sensitivity. We present a study of an abort gap monitor based on a photomultiplier with a gated microchannel plate, which would allow for detecting low charge densities by monitoring the synchrotron radiation emitted. We show results of beam test experiments at the Advanced Light Source using a Hamamatsu 5916U MCP-PMT and compare them to the specifications for the Large Hadron Collider

Abortion in adolescence: a four-country comparison.
Welsh, P; McCarthy, M; Cromer, B
2001-01-01
The purpose of this study was to conduct a comparison, using qualitative analytic methodology, of perceptions concerning abortion among health care providers and administrators, along with politicians and anti-abortion activists (total n = 75) in Great Britain, Sweden, The Netherlands, and the United States. In none of these countries was there consensus about abortion prior to legalization, and, in all countries, public discussion continues to be present. In general, after legalization of abortion has no longer made it a volatile issue European countries have refocused their energy into providing family planning services, education, and more straightforward access to abortion compared with similar activities in the United States.

Late Abortion: A Comprehensive Review

Sheng Chiang

Full Text Available Late termination of pregnancy (LTOP is defined as an abortion carried out beyond 24 gestational weeks, when the fetus has arguably attained viability. In Taiwan, the current abortion law, bearing a eugenic title, allows LTOP on certain medical grounds. However, the fetal and maternal conditions that constitute medical grounds are not clarified and remain legally untested. Professional debate on the abortion issue is also lacking in academia in Taiwan, despite societal concerns. With the advent of technology to detect fetal abnormalities, obstetricians are now confronted more frequently with acute dilemmas regarding LTOP. Quite often, they sail in an uncharted sea with no clinical guidelines from their professional societies or affiliated hospitals. Recently, LTOP at 35 gestational weeks for a fetus with Down syndrome, complicated with polyhydramnios and tetralogy of Fallot, triggered media scrutiny and aroused much public attention. Although the clinical decision making for pregnancies with fetal abnormalities entails increasingly balanced information and consideration in terms of the medical, ethical, legal, psychologic, and societal aspects, society at large is unaware of the complexity and intertwined nature of various abortion issues, especially LTOP. Obstetricians are now in a vulnerable position in Taiwanese society, where litigations relevant to the practice of early abortions are not rare. Therefore, a global and in-depth look into abortion issues from legal and ethical dimensions is indispensable for modern obstetric practice. This review considers the core issues in LTOP, including what conditions constitute a “serious” fetal abnormality to justify LTOP, the incidence of LTOP, legislation regarding LTOP in Western countries, and recent research on ambivalent fetal pain. It will also present procedures, some under the auspices of the ethical committee of a Presbyterian hospital in Taiwan, for clinical decision making, particularly

Full Text Available Objective: The aim of this study was to investigate the opinions of women who presented to the hospital for elective abortion. Materials and Methods: This descriptive study was designed and conducted at our university hospital between March 2013-April 2013 by the method of face-to-face interviews with 500 women who presented to the hospital as patient or relatives of patients. Poll consisted of 6 questions about demographic characteristics and 14 questions evaluating the opinions and attitudes about abortion. Results: The age of the women who participated in the study was ranging between 18 and 75 years with the mean age of 31.5±11.9 years. Twenty-six women (5.2% were illiterate, while 109 (21.8% were university graduates. 70.8% of women stated that they were against elective abortion. Among the reasons against abortion on request were: “forbidden by the religion”-53.1% of women, “against human rights”-35.3%, and “unhealthy for the mother”-7.1% of women. About the prohibition of abortion, 82.4% of women said that “it may be performed under necessary conditions”, 9.6% “it should be completely forbidden”, and 8% stated that “it should never be forbidden”. Conclusion: A large number of respondents reported that they have negative attitude towards elective abortion, however, in case of medical necessity, abortion should be performed. During the legal arrangements done about situations that may affect the public health, such as abortion regulations, we believe it would be useful to assess the perspective of the society on this issue.
Anti-abortion policy leads to more abortions.
Jacobson, J L
1988-01-01
In 1984, the Reagan administration announced in Mexico City a reversal in the US international family planning policy. The new policy strictly forbids any international family planning group that receives US funds from providing abortion services or counseling. An immediate impact on family planning programs in developing countries was that it prevented the opening of much needed clinics in the poorest, most rapidly growing countries in the world, such as Bangladesh. The University of Michigan School of Public Health estimates an additional 380,000 unwanted pregnancies, resulting in 311,000 births, 69,000 abortions, and 1200 maternal deaths in the next 3 years. Not only did the US change its policy, but congress decreased funding for international family planning programs 20% between 1985 and 1987. The majority of the funding goes to the US Agency for International Development (USAID), and in 1988 the Reagan administration allowed USAID to funnel about $75 million of this money to other projects, e.g. general African development fund. Fewer contraceptives are available due to the reduced funding, and therefore more women seek an abortion as a last resort against unwanted pregnancy. An additional effect of this 1984 policy reversal is that fewer nongovernmental organizations (NGOs) are eligible for grants, so USAID gives its family planning funds to government agencies who are not the most effective users of funds and are not always trusted by the people served.
Evidence Supporting Broader Access To Safe Legal Abortion
Faundes; Anibal; Shah; Iqbal H.
2016-01-01
Unsafe abortion continues to be a major cause of maternal death; it accounts for 14.5% of all maternal deaths globally and almost all of these deaths occur in countries with restrictive abortion laws. A strong body of accumulated evidence shows that the simple means to drastically reduce unsafe abortion-related maternal deaths and morbidity is to make abortion legal and institutional termination of pregnancy broadly accessible. Despite this evidence, abortion is denied even when the legal con...
Normobaric hypoxia inhalation test vs. response to airline flight in healthy passengers.
Kelly, Paul T; Swanney, Maureen P; Frampton, Chris; Seccombe, Leigh M; Peters, Matthew J; Beckert, Lutz E
2006-11-01
There is little data available to determine the normal response to normobaric hypoxia inhalation testing (NHIT) and air travel. Quantifying a healthy response may assist in the evaluation of passengers considered at risk for air travel. The aims of this study were: (1) to quantify the degree of desaturation in healthy subjects during a NHIT and air travel; and (2) assess the validity of the NHIT when compared with actual in-flight responses. There were 15 healthy adults (age 23-57; 10 women) who volunteered for this study. Preflight tests included lung function, arterial blood gas, pulse oximetry (SpO2), and NHIT (inspired oxygen 15%). SpO2 and cabin pressure were measured continuously on each subject during a commercial air flight (mean cabin altitude 2178 m; range 1719-2426 m). In-flight oxygenation was compared with the preflight NHIT. Lung function testing results were normal. There was significant desaturation (SpO2) during the NHIT (pre: 98 +/- 2%; post: 92 +/- 2%) and at cruising altitude (pre: 97 +/- 1%; cruise: 92 +/- 2%). There was no difference between the final NHIT SpO2 and the mean in-flight SpO2. There was a significant difference between the lowest in-flight SpO2 (88 +/- 2%) vs. the lowest NHIT SpO2, (90 +/- 2%). Oxygen saturation decreases significantly during air travel in normal individuals. In this group of healthy passengers the NHIT approximates some, but not all, aspects of in-flight oxygenation. These results can be used to describe a normal response to the NHIT and air-travel.

Researchers at the National Aeronautics and Space Administration Armstrong Flight Research Center in Edwards, California and Vigilant Aerospace Systems collaborated for the flight-test demonstration of an Automatic Dependent Surveillance-Broadcast based collision avoidance technology on a small unmanned aircraft system equipped with the uAvionix Automatic Dependent Surveillance-Broadcast transponder. The purpose of the testing was to demonstrate that National Aeronautics and Space Administration / Vigilant software and algorithms, commercialized as the FlightHorizon UAS"TM", are compatible with uAvionix hardware systems and the DJI Phantom 4 small unmanned aircraft system. The testing and demonstrations were necessary for both parties to further develop and certify the technology in three key areas: flights beyond visual line of sight, collision avoidance, and autonomous operations. The National Aeronautics and Space Administration and Vigilant Aerospace Systems have developed and successfully flight-tested an Automatic Dependent Surveillance-Broadcast Detect and Avoid system on the Phantom 4 small unmanned aircraft system. The Automatic Dependent Surveillance-Broadcast Detect and Avoid system architecture is especially suited for small unmanned aircraft systems because it integrates: 1) miniaturized Automatic Dependent Surveillance-Broadcast hardware; 2) radio data-link communications; 3) software algorithms for real-time Automatic Dependent Surveillance-Broadcast data integration, conflict detection, and alerting; and 4) a synthetic vision display using a fully-integrated National Aeronautics and Space Administration geobrowser for three dimensional graphical representations for ownship and air traffic situational awareness. The flight-test objectives were to evaluate the performance of Automatic Dependent Surveillance-Broadcast Detect and Avoid collision avoidance technology as installed on two small unmanned aircraft systems. In December 2016, four flight tests

Discussing the abortion theme in Brazil is highly problematic since it involves ethical, moral and legal precepts. The criminalization of abortion in Brazil favors a clandestine and unsafe practice and can lead to serious consequences to women´s health. In this perspective, this research deals with the legal context in which the abortion problem is inscribed in Brazil, coupled to the specific aims in pinpointing complications caused by the criminalization of clandestine abortion besides deali...

Reproductive rights: Current issues of late abortion
Directory of Open Access Journals (Sweden)
Mujović-Zornić Hajrija
2009-01-01
Full Text Available This article considers the legal issues surrounding induced late abortion in cases when severe medical, therapeutic or ethical reasons have not been in dispute. Generally discussing the essential question about abortion today, it means not anymore legality of abortion but, in the first place, safety of abortion. From the aspect of woman health the most important aim is to detect and avoid possible risks of medical intervention, such as late abortion present. This is the matter of medical law context and also the matter of the woman's reproductive rights, here observed through legislation and court practice. The gynecologist has an obligation to obtain the informed consent of each patient. Information's should be presented in reasonably understandable terms and include alternative modes of treatment, objectives, risks, benefits, possible complications, and anticipated results of such treatment. Pregnant woman should receive supportive counseling before and particularly after the procedure. The method chosen for all terminations should ensure that the fetus is born dead. This should be undertaken by an appropriately trained practitioner. Reform in abortion law, making it legally accessible to woman, is not necessarily the product of a belief in woman's rights, but can be a means of bringing the practice of abortion back under better control. Counseling and good medical practice in performing late abortion are the instruments to drive this point even further home. It does not undermine the woman who wants to make a positive decision about her life and its purpose is not to produce feelings of insecurity and guilt. It concludes that existing law should not be changed but that clear rules should be devised and board created to review late term abortion. In Serbia, this leads to creation and set up guidelines for reconciling medical justification for late abortion with existing law, especially with solutions which brings comparative law. .
If war is "just," so is abortion.
Kissling, F
1991-01-01
Currently Catholic bishops are applying an inconsistent ethical paradigm to the issues of war and abortion. Based on the seamless garment theory war, abortion and capital punishment are all immoral acts because they are of the same garment. They are all "killing acts" and as such they are immoral. However there is within the Catholic paradigm the idea of a just war. The just war theory states that the destruction of human life in war is justified if it is for a greater good. However abortion has no exceptions, there is no just abortion in the rules of the Catholic Church. The author takes the just war doctrine as presented by the Catholic Church and shows how it could easily apply to abortion. Both war and abortion involve the taking of a human life, but in the case of war the taking of a life is justified if it is done to protect your own life. The same exception in abortion would be to allow abortion when the mother's life is in danger. yet no such exception exists. The just war theory further states that was is necessary to protect national integrity, particularly if the violation erodes the quality of life for its citizens. The same exception for abortion would include allowing abortions for women who already have more children then they can care for or if having the child would erode the quality of life for the woman. Other aspects of the just war theory include the competence and goals of the national leaders. Women must also be allowed to be competent moral agents. Proponents of the seamless garment theory will bring up the fact that in a just war only combatants die yet the fetus is innocent. But no war has ever been fought without the loss of innocent civilians.

Skewed male:female ratios at birth have been observed among certain immigrant groups. Data on abortion practices that might help to explain these findings are lacking. We examined 1 220 933 births to women with up to 3 consecutive singleton live births between 1993 and 2012 in Ontario. Records of live births, and induced and spontaneous abortions were linked to Canadian immigration records. We determined associations of male:female infant ratios with maternal birthplace, sex of the previous living sibling(s) and prior spontaneous or induced abortions. Male:female infant ratios did not appreciably depart from the normal range among Canadian-born women and most women born outside of Canada, irrespective of the sex of previous children or the characteristics of prior abortions. However, among infants of women who immigrated from India and had previously given birth to 2 girls, the overall male:female ratio was 1.96 (95% confidence interval [CI] 1.75-2.21) for the third live birth. The male:female infant ratio after 2 girls was 1.77 (95% CI 1.26-2.47) times higher if the current birth was preceded by 1 induced abortion, 2.38 (95% CI 1.44-3.94) times higher if preceded by 2 or more induced abortions and 3.88 (95% CI 2.02-7.50) times higher if the induced abortion was performed at 15 weeks or more gestation relative to no preceding abortion. Spontaneous abortions were not associated with male-biased sex ratios in subsequent births. High male:female ratios observed among infants born to women who immigrated from India are associated with induced abortions, especially in the second trimester of pregnancy. © 2016 Canadian Medical Association or its licensors.

Abortion in Iranian legal system: a review.
Abbasi, Mahmoud; Shamsi Gooshki, Ehsan; Allahbedashti, Neda
2014-02-01
Abortion traditionally means, "to miscarry" and is still known as a problem which societies has been trying to reduce its rate by using legal means. Despite the pregnant women and fetuses have being historically supported; abortion was firstly criminalized in 1926 in Iran, 20 years after establishment of modern legal system. During next 53 years this situation changed dramatically, so in 1979, the time of Islamic Revolution, aborting fetuses before 12 weeks and therapeutic abortion (TA) during all the pregnancy length was legitimate, based on regulations that used medical justification. After 1979 the situation changed into a totally conservative and restrictive approach and new Islamic concepts as "Blood Money" and "Ensoulment" entered the legal debates around abortion. During the next 33 years, again a trend of decriminalization for the act of abortion has been continuing. Reduction of punishments and omitting retaliation for criminal abortions, recognizing fetal and maternal medical indications including some immunologic problems as legitimate reasons for aborting fetuses before 4 months and omitting the fathers' consent as a necessary condition for TA are among these changes. The start point for this decriminalization process was public and professional need, which was responded by religious government, firstly by issuing juristic rulings (Fatwas) as a non-official way, followed by ratification of "Therapeutic Abortion Act" (TAA) and other regulations as an official pathway. Here, we have reviewed this trend of decriminalization, the role of public and professional request in initiating such process and the rule-based language of TAA.

Full Text Available To satisfy the validation requirements of flight control law for advanced aircraft, a wind tunnel based virtual flight testing has been implemented in a low speed wind tunnel. A 3-degree-of-freedom gimbal, ventrally installed in the model, was used in conjunction with an actively controlled dynamically similar model of aircraft, which was equipped with the inertial measurement unit, attitude and heading reference system, embedded computer and servo-actuators. The model, which could be rotated around its center of gravity freely by the aerodynamic moments, together with the flow field, operator and real time control system made up the closed-loop testing circuit. The model is statically unstable in longitudinal direction, and it can fly stably in wind tunnel with the function of control augmentation of the flight control laws. The experimental results indicate that the model responds well to the operator’s instructions. The response of the model in the tests shows reasonable agreement with the simulation results. The difference of response of angle of attack is less than 0.5°. The effect of stability augmentation and attitude control law was validated in the test, meanwhile the feasibility of virtual flight test technique treated as preliminary evaluation tool for advanced flight vehicle configuration research was also verified.

Comment: unethical ethics investment boycotts and abortion.
Furedi, A
1998-01-01
Ethical investment funds have traditionally boycotted the arms industry, companies known to pollute the environment, and those involved in animal research. However, recent newspaper reports suggest that some investment funds plan to also boycott hospitals and pharmaceutical companies involved in abortion-related activities. Ethical Financial, anti-abortion independent financial advisors, are encouraging a boycott of investment in private hospitals and manufacturers of equipment involved in abortions, and pharmaceutical firms which produce postcoital contraception or conduct embryo research. Ethical Financial claims that Family Assurance has agreed to invest along anti-abortion lines, Aberdeen Investment is already boycotting companies linked to abortion, and Hendersons ethical fund plans to follow suit. There is speculation that Standard Life, the largest mutual insurer in Europe, will also refuse to invest in abortion-related concerns when it launches its ethical fund in the spring. Managers of ethical funds should, however, understand that, contrary to the claims of the anti-choice lobby, there is extensive public support for legal abortion, emergency contraception, and embryo research. Individuals and institutions which contribute to the development of reproductive health care services are working to alleviate the distress of unwanted pregnancy and infertility, laudable humanitarian goals which should be encouraged. Those who try to restrict the development of abortion methods and services simply show contempt for women, treating them as people devoid of conscience who are incapable of making moral choices.
Boundary Layer Transition During the Orion Exploration Flight Test 1 (EFT-1)
Kirk, Lindsay C.
2016-01-01
Boundary layer transition was observed in the thermocouple data on the windside backshell of the Orion reentry capsule. Sensors along the windside centerline, as well as off-centerline, indicated transition late in the flight at approximately Mach 4 conditions. Transition progressed as expected, beginning at the sensors closest to the forward bay cover (FBC) and moving towards the heatshield. Sensors placed in off-centerline locations did not follow streamlines, so the progression of transition observed in these sensors is less intuitive. Future analysis will include comparisons to pre-flight predictions and expected transitional behavior will be investigated. Sensors located within the centerline and off-centerline launch abort system (LAS) attach well cavities on the FBC also showed indications of boundary layer transition. The transition within the centerline cavity was observed in the temperature traces prior to transition onset on the sensors upstream of the cavity. Transition behavior within the off centerline LAS attach well cavity will also be investigated. Heatshield thermocouples were placed within Avcoat plugs to attempt to capture transitional behavior as well as better understand the aerothermal environments. Thermocouples were placed in stacks of two or five vertically within the plugs, but the temperature data obtained at the sensors closest to the surface did not immediately indicate transitional behavior. Efforts to use the in depth thermocouple temperatures to reconstruct the surface heat flux are ongoing and any results showing the onset of boundary layer transition obtained from those reconstructions will also be included in this paper. Transition on additional features of interest, including compression pad ramps, will be included if it becomes available.
Brazilian abortion law: the opinion of judges and prosecutors.
Duarte, Graciana Alves; Osis, Maria José Duarte; Faúndes, Anibal; Sousa, Maria Helena de
2010-06-01
To analyze the opinion of judges and prosecutors concerning Brazilian abortion law and situations in which the abortion should be allowed. A cross-sectional study was performed with 1,493 judges and 2,614 prosecutors in Brazil between 2005 and 2006. Participants completed a structured questionnaire approaching sociodemographic characteristics, opinions about abortion law, and circumstances in which abortion is considered lawful. Bivariate and multivariate analyses of data were carried out through Poisson regression. The majority of participants (78%) found that the circumstances in which abortion is considered lawful should be broadened, or even that abortion should not be criminalized. The highest rates of pro-abortion opinions resulted from: risk to the life of the mother (84%), anencephaly (83%), severe congenital malformation of fetus (82%), and pregnancy resulting from rape (82%). Variables related to religion were strongly associated to the opinion of participants. There is a trend in considering the need of changing the current abortion law, in the sense of widening the circumstances in which abortion is considered lawful, or even toward decriminalizing abortion, regardless of the circumstances in which it takes place.
Unsafe abortion: a tragic saga of maternal suffering.
Regmi, M C; Rijal, P; Subedi, S S; Uprety, D; Budathoki, B; Agrawal, A
2010-01-01
Unsafe abortion is a significant cause of maternal morbidity and mortality in developing countries despite provision of adequate care and legalization of abortion. The aim of this study was to find out the contribution of unsafe abortion in maternal mortality and its other consequences. A retrospective study was carried out in the Department of Obstetrics and Gynecology in BPKIHS between 2005 April to 2008 September analyzing all the unsafe abortion related admissions. There were 70 unsafe abortion patients. Majority of them (52.8%) were of high grade. Most of them recovered but there were total 8 maternal deaths. Unsafe abortion is still a significant medical and social problem even in post legalization era of this country.
A comparison of theory and flight test of the BO 105/BMR in hover and forward flight
Mirick, Paul H.
1988-01-01
Four cases were selected for comparison with theoretical predictions using stability data obtained during the flight test of the Bearingless Main Rotor (BMR) on a Messerschmidt-Boelkow-Blohm BO 105 helicopter. The four cases selected form the flight test included two ground resonance cases and two air resonance cases. The BMR used four modified BO 105 blades attached to a bearingless hub. The hub consisted of dual fiberglass C-channel beams attached to the hub center at 0.0238R and attached to the blade root at 0.25R with blade pitch control provided by a torque tube. Analyses from Bell Helicopter Textron, Boeing Vertol, and Sikorsky Aircraft were compared with the data and the correlation ranged from very poor-to-poor to poor-to-fair.

We revised ethical concepts related to abortion from the points of view of the mothers; life, health, and considerations are made concerning the embryo or fetus as a biological, ontological, moral, and potential person. Certain religious matters on abortion are described and commented on. Effects of abortion penalization in Mexico and the legislation in the Mexican states are examined, as well as the motives of depenalization in certain countries.

A 15-year-old girl at 18 weeks gestation by the last menstrual period presented to a rural Ugandan healthcare facility for termination of her pregnancy as a result of rape by her uncle. Skilled healthcare workers at the facility refused to provide the abortion due to fear of legal repercussions. The patient subsequently obtained an unsafe abortion by vaginal insertion of local herbs and sharp objects. She developed profuse vaginal bleeding and haemorrhagic shock. She was found to have uterine rupture and emergent hysterectomy was performed. Young and poor women are at high risk of unplanned pregnancy and subsequent mortality during pregnancy and childbirth. Unsafe abortion is a leading and entirely preventable cause of maternal mortality worldwide. Multiple barriers restrict access to safe abortions including social and moral stigma, gender-based power imbalances, inadequate contraceptive use and sexual education, high cost and poor availability, and restrictive abortion laws. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

[Decriminalization of abortion: a common purpose in Latin America].
1993-12-01
In the conviction that abortion is a fundamental right of women and that its illegal practice constitutes a serious threat to life, several Latin American women's groups have united to work for decriminalization. The groups have been attempting to increase public awareness of the consequences of illegal abortion. Official silence on the topic appears to deny the existence of a problem. Proposals in the different Latin American countries are adapted to their political and legal circumstances. In Argentina, a campaign has been underway for nearly two years to collect signatures for a petition for a law concerning contraception and abortion. The National Network for Women's Health and other groups have held regional and national workshops on the issue. In Bolivia, radio and television programs have been broadcast in Spanish and indigenous languages on the right to choose, reproductive health, and sex education. Abortion was debated in Brazil during the process of constitutional reform, but it remains illegal. Illegal abortion continues to be a reality and women's groups are lobbying for decriminalization. Abortion is considered a crime in Colombia's penal code. Attempts to legalize abortion have been rejected by the legislature without debate. The practice of abortion under the circumstances has become a lucrative business whose lack of regulation has resulted in a growing number of maternal deaths. Attempts are underway in Costa Rica to legalize abortion in cases of rape or incest. Studies show that illegal abortion is the third most important cause of maternal death. A bill to legalize abortion is under study in Chile's Parliament but has not been approved. Abortion is illegal but common in Ecuador. Efforts are underway in Mexico and Nicaragua to encourage debate on abortion. Peru's Health Commission was recently prevented from classifying abortion for any reason other than grave congenital anomaly as homicide. Abortion has been legal in Puerto Rico since 1974, but

Updated clinical recommendations for medical induced abortion procedure. A systematic review of French and English literature, reviewing the evidence relating to the provision of medical induced abortion was carried out on PubMed, Cochrane Library and international scientific societies recommendations. The effectiveness of medical abortion is higher than 95% when the protocols are adjusted to gestational age (EL1). Misoprostol alone is less effective than a combination of mifepristone and misoprostol (EL1). Gemeprost is less effective than misoprostol (EL2). The dose of 200mg of mifepristone should be preferred to 600mg (NP1, Rank A). Mifepristone can be taken at home (professional agreement). The optimum interval between mifepristone and misoprostol intake should be 24 to 48 hours (EL1, grade A). Before 7 weeks LMP, the dose of 400μg misoprostol should be given orally (EL1, grade A) eventually repeated after 3hours if no bleeding occurs. For optimal effectiveness between 7 and 14 LMP, the interval between mifepristone and misoprostol should not be shortened to less than 8hours (grade 1). An interval of 24 to 48hours will not affect the effectiveness of the method provided misoprostol dosage is 800μg (EL1). Vaginal, sublingual or buccal routes of administration are more effective and better tolerated than the oral route, which should be abandoned (EL1). An amount of 800μg sublingual or buccal misoprostol route has the same effectiveness than the vaginal route but more gastrointestinal side effects (EL1, grade A). Between 7 and 9 LMP, it does not seem necessary to repeat misoprostol dose whereas it should be repeated beyond 9 SA (grade B). Between 9 and 14 LMP, the dose of 400μg misoprostol given either vaginally, buccally or sublingually should be repeated every 3hours if needed (with a maximum of 5 doses) (EL2, grade B). There is no strong evidence supporting routine antibiotic prophylaxis for medical abortion (professional agreement). Rare contraindications
Characteristics of private abortion services in Mexico City after legalization.
Schiavon, Raffaela; Collado, Maria Elena; Troncoso, Erika; Soto Sánchez, José Ezequiel; Zorrilla, Gabriela Otero; Palermo, Tia
2010-11-01
In 2007, first trimester abortion was legalized in Mexico City, and the public sector rapidly expanded its abortion services. In 2008, to obtain information on the effect of the law on private sector abortion services, we interviewed 135 physicians working in private clinics, located through an exhaustive search. A large majority of the clinics offered a range of reproductive health services, including abortions. Over 70% still used dilatation and curettage (D&C); less than a third offered vacuum aspiration or medical abortion. The average number of abortions per facility was only three per month; few reported more than 10 abortions monthly. More than 90% said they had been offering abortion services for less than 20 months. Many women are still accessing abortion services privately, despite the availability of free or low-cost services at public facilities. However, the continuing use of D&C, high fees (mean of $157-505), poor pain management practices, unnecessary use of ultrasound, general anaesthesia and overnight stays, indicate that private sector abortion services are expensive and far from optimal. Now that abortions are legal, these results highlight the need for private abortion providers to be trained in recommended abortion methods and quality of private abortion care improved.

Full Text Available Introduction & Objective: Nowadays, some studies indicate the adverse effects of exposure to chemicals, especially organic solvents on the reproductive system of females. This study aimed to assess the relationship between spontaneous abortion with occupational exposure to organic solvents in pharmaceutical industry. Materials & Methods: This is a cross-sectional and descriptive-analytical study which was carried out in 2010 in one of the pharmaceutical factories located in the suburbs of Tehran. During the study, married women who were working in the factory laboratory units and were exposed to mixed organic solvents were compared with married women who were working in the packing units of the factory without occupational exposure to organic solvents. Frequency of spontaneous abortion and duration of pregnancy were assessed in both two groups. Collected data were analyzed with the SPSS software using t-test, logistic regression, and chi-square test. Results: In the present study, the frequency of spontaneous abortion in employees with exposure to organic solvents mixture was 10.7%. This study showed that even after adjustment for confounding factors, there was a significant correlation between spontaneous abortion and occupational exposure to organic solvents mixture and this correlation increased with increasing levels of exposure to organic solvents. Moreover, a significant correlation was observed between occupational exposure to mixed organic solvents and waiting time to become pregnant (TTP. Furthermore, this study showed that even after adjustment for confounding variables, shift workers were significantly more affected by spontaneous abortion compared to daytime workers (P < 0.001. Conclusion: According to the results of this study, since there is probability of spontaneous abortion resulting from occupational exposure to various chemicals including organic solvents, review of the status of occupational exposure of workers can be helpful

As part of the Stratospheric Observatory for Infrared Astronomy (SOFIA) program, a 747SP airplane was modified to carry a 2.5 meter telescope in the aft section of the fuselage. The resulting airborne observatory allows for observations above 99 percent of the water vapor in the atmosphere. The open cavity created by the modifications had the potential to significantly affect the airplane in the areas of aerodynamics and acoustics. Several series of flight tests were conducted to clear the airplanes operating envelope for astronomical observations, planned to be performed between the altitudes of 39,000 feet and 45,000 feet. The flight tests were successfully completed. Cavity acoustics were below design limits, and the overall acoustic characteristics of the cavity were better than expected. The modification did have some effects on the stability and control of the airplane, but these effects were not significant. Airplane air data systems were not affected by the modifications. This paper describes the methods used to examine the aerodynamics and acoustic data from the flight tests and provides a discussion of the flight test results in the areas of cavity acoustics, stability and control, and air data.
Psychological sequelae of induced abortion.
Romans-Clarkson, S E
1989-12-01
This article reviews the scientific literature on the psychological sequelae of induced abortion. The methodology and results of studies carried out over the last twenty-two years are examined critically. The unanimous consensus is that abortion does not cause deleterious psychological effects. Women most likely to show subsequent problems are those who were pressured into the operation against their own wishes, either by relatives or because their pregnancy had medical or foetal contraindications. Legislation which restricts abortion causes problems for women with unwanted pregnancies and their doctors. It is also unjust, as it adversely most affects lower socio-economic class women.

In 2005 Ethiopia took the important step to protect women's reproductive health by liberalizing the abortion law. As a result women were given access to safe pregnancy termination in first and second trimester. This study aims to describe socio-economic characteristics and contraceptive experience among women seeking abortion in Jimma, Ethiopia and to describe determinants of second trimester abortion. A cross-sectional study conducted October 2011 - April 2012 in Jimma Town, Ethiopia among women having safely induced abortion and women having unsafely induced abortion. In all 808 safe abortion cases and 21 unsafe abortion cases were included in the study. Of the 829 abortions, 729 were first trimester and 100 were second trimester abortions. Bivariate and multivariate logistic regressions were used to determine risk factors associated with second trimester abortion. The associations are presented as odds ratios (OR) with 95% confidential intervals. Age stratified analyses of contraceptive experience among women with first and second trimester abortions are also presented. Socio-economic characteristics associated with increased ORs of second trimester abortion were: age abortion where only 15% and 19% stated they had ever used contraception. Young age, poor education and the prospect of single parenthood were associated with second trimester abortion. Young girls and young women were using contraception comparatively less often than older women. To ensure women full right to control their fertility in the setting studied, modern contraception should be made available, accessible and affordable for all women, regardless of age.

To evaluate Turkish nursing students' attitudes towards voluntary induced abortion.. This cross-sectional study was conducted between January and June 2015, comprising students of Ege University Nursing Faculty and Celal Bayar University School of Health, located in two different cities of Turkey. Data was collected with a three-part questionnaire, focussing on students' characteristics, the knowledge of abortion law in Turkey and attitudes towards voluntary induced abortion. SPSS 15 was used for data analysis.. The mean score of students' attitude towards voluntary induced abortion was 39.8±7.9 which shows that nursing students moderately support abortion. Female students, students coming from upper class in society, and students who had higher family income and sexual experiences had more supportiveness attitudes towards voluntary induced abortion (pabortion.

Induced abortion is more frequent in Sweden than in many other Western countries. We wanted to investigate attitudes and knowledge about induced abortion among politicians responsible for healthcare in three Swedish counties. A study-specific questionnaire was sent to all 375 elected politicians in three counties; 192 (51%) responded. The politicians stated that they were knowledgeable about the Swedish abortion law. More than half did not consider themselves, in their capacity as politicians, sufficiently informed about abortion-related matters. Most politicians (72%) considered induced abortion to be primarily a 'women's rights issue' rather than an ethical one, and 54% considered 12 weeks' gestational age an adequate upper limit for induced abortion. Only about a third of the respondents were correctly informed about the number of induced abortions annually carried out in Sweden. Information and knowledge on induced abortion among Swedish county politicians seem not to be optimal. Changes aimed at reducing the current high abortion rates will probably not be easy to achieve as politicians seem to be reluctant to commit themselves on ethical issues and consider induced abortion mainly a women's rights issue.

The aim of performed study was to determine the level of enzootic abortion (EA) in sheep breeding farms in different districts of Lithuania, to determine differences in clinical signs and infection frequency between various age groups, and to evaluate the sensitivity and specificity of complement fixation test for antibodies detection and indirect immunofluorescence for antigen detection in sheep chlamydiosis. The clinical, serological and immunological tests in sheep farms were performed in 2004 and 2005. Comparing different age groups of sheep revealed that the lowest number of infected sheep was registered in animals younger than 18 months (23.1%, antibodies titre 3.191 log2, Pabortus infection. The highest prevalence of chlamydia (66.7%) was registered in placentas of sheep which aborted.

Background. To study the risk of placenta complications following an induced abortion as a function of the interpregnancy interval. Methods. This study is based on three Danish national registries; the Medical Birth Registry, the Hospital Discharge Registry, and the Induced Abortion Registry. All...... primigravida women from 1980 to 1982 were identified in these three registries. A total of 15,727 women who terminated the pregnancy with a first trimester induced abortion were selected to the abortion cohort, and 46,026 women who did not terminate the pregnancy with an induced abortion constituted...... or the Medical Birth Registry records. Results. A slightly higher risk of placenta complications following an abortion was found. Retained placenta occurred more frequently in women with one, two or more previous abortions, compared with women without any previous abortion of similar gravidity. Adjusting...
Pre-Flight Tests with Astronauts, Flight and Ground Hardware, to Assure On-Orbit Success
Haddad Michael E.
2010-01-01
On-Orbit Constraints Test (OOCT's) refers to mating flight hardware together on the ground before they will be mated on-orbit or on the Lunar surface. The concept seems simple but it can be difficult to perform operations like this on the ground when the flight hardware is being designed to be mated on-orbit in a zero-g/vacuum environment of space or low-g/vacuum environment on the Lunar/Mars Surface. Also some of the items are manufactured years apart so how are mating tasks performed on these components if one piece is on-orbit/on Lunar/Mars surface before its mating piece is planned to be built. Both the Internal Vehicular Activity (IVA) and Extra-Vehicular Activity (EVA) OOCT's performed at Kennedy Space Center will be presented in this paper. Details include how OOCT's should mimic on-orbit/Lunar/Mars surface operational scenarios, a series of photographs will be shown that were taken during OOCT's performed on International Space Station (ISS) flight elements, lessons learned as a result of the OOCT's will be presented and the paper will conclude with possible applications to Moon and Mars Surface operations planned for the Constellation Program.
Full-scale flight tests of aircraft morphing structures using SMA actuators
Mabe, James H.; Calkins, Frederick T.; Ruggeri, Robert T.
2007-04-01
In August of 2005 The Boeing Company conducted a full-scale flight test utilizing Shape Memory Alloy (SMA) actuators to morph an engine's fan exhaust to correlate exhaust geometry with jet noise reduction. The test was conducted on a 777-300ER with GE-115B engines. The presence of chevrons, serrated aerodynamic surfaces mounted at the trailing edge of the thrust reverser, have been shown to greatly reduce jet noise by encouraging advantageous mixing of the free, and fan streams. The morphing, or Variable Geometry Chevrons (VGC), utilized compact, light weight, and robust SMA actuators to morph the chevron shape to optimize the noise reduction or meet acoustic test objectives. The VGC system was designed for two modes of operation. The entirely autonomous operation utilized changes in the ambient temperature from take-off to cruise to activate the chevron shape change. It required no internal heaters, wiring, control system, or sensing. By design this provided one tip immersion at the warmer take-off temperatures to reduce community noise and another during the cooler cruise state for more efficient engine operation, i.e. reduced specific fuel consumption. For the flight tests a powered mode was added where internal heaters were used to individually control the VGC temperatures. This enabled us to vary the immersions and test a variety of chevron configurations. The flight test demonstrated the value of SMA actuators to solve a real world aerospace problem, validated that the technology could be safely integrated into the airplane's structure and flight system, and represented a large step forward in the realization of SMA actuators for production applications. In this paper the authors describe the development of the actuator system, the steps required to integrate the morphing structure into the thrust reverser, and the analysis and testing that was required to gain approval for flight.

This article presents the results of a study in the city of São Paulo, Brazil, aimed at estimating the frequency of induced abortion among women 15 to 49 years of age. The objective was to characterize the occurrence of induced abortion by comparing the ideal number of children, age, and contraceptive use between married and single women. Based on random sampling, 1,749 interviews were held, including 764 married women, 658 single women, and 327 with other marital status. The analysis included: mean number of abortions per woman by analysis of variance and proportions of abortions and pregnancy, using the chi-square test. The mean abortion rate for married women (45 per thousand) did not differ statistically from that of single women. However, the pregnancy rate was much lower in single women, and when single women became pregnant they used abortion more frequently; while fewer than 2% of pregnancies in married women ended in induced abortions, among single women the abortion rate exceeded 18%. Therefore, the priority in the reproductive health field should be to invest in the supply and dissemination of appropriate contraceptive methods for women's early sexually active life.

Enzootic abortion of ewes (EAE) is caused by infection of sheep and goats by Chlamydia abortus bacterium. Chlamydial abortion in bovine could occur by Chlamydia abortus, Chlamydia psittaci and Chlamydia pecorum. C. psittaci is the causative agent of psittacosis or ornithosis disease in humans and birds. It also causes acute pneumonia in cattle and sheep. The present study aimed at surveying the role of chlamydial agents in ruminants abortion. A total of 117 aborted material samples (Cotyledon, liver, spleen, and abomasal contents of fetus) from 9 cattle and 100 sheep in Shahr-e-Kord and 8 sheep from Bagh-e-Malek were collected from different herds with abortion history during the lambing periods from 2014 to 2016. After DNA extraction, the samples were tested by species-specific PCR to detect C. abortus, C. pecorum and C. psittaci. Out of 117 clinical sample (108 sheep and 9 cattle), chlamydial infection was detected in 66 (56.41%) samples by Chlamydiales order-specific primers. A total of 24 (36.36%) and 24 (36.36%) samples indicated positive forms of C. abortus and C. psittasi infections, respectively. Only 1 (1.5%) C. pecorum was identified from cattle using nested PCR during this study. Among 66 Chlamydiales -positive samples, 20 (30.30%) samples with coinfection of C. abortus and C. psittaci were detected, however, infection of 3 species was not detected in the samples. Because of the high percentage of chlamydial infection in these regions and probability of coinfection, conducting epidemiological studies on the role of different animals is highly recommended.

A flight investigation was conducted to evaluate a multi-mode flight control system designed according to the most recent recommendations for handling qualities criteria for new military helicopters. The modes and capabilities that were included in the system are those considered necessary to permit divided-attention (single-pilot) lowspeed and hover operations near the ground in poor visibility conditions. Design features included mode-selection and mode-blending logic, the use of an automatic position-hold mode that employed precision measurements of aircraft position, and a hover display which permitted manually-controlled hover flight tasks in simulated instrument conditions. Pilot evaluations of the system were conducted using a multi-segment evaluation task. Pilot comments concerning the use of the system are provided, and flight-test data are presented to show system performance.
Chlamydiaceae family, Parachlamydia spp., and Waddlia spp. in porcine abortion.

At present, despite extensive laboratory investigations, most cases of porcine abortion remain without an etiological diagnosis. Due to a lack of recent data on the abortigenic effect of order Chlamydiales, 286 fetuses and their placentae of 113 abortion cases (1-5 fetuses per abortion case) were investigated by polymerase chain reaction (PCR) methods for family Chlamydiaceae and selected Chlamydia-like organisms such as Parachlamydia acanthamoebae and Waddlia chondrophila. In 0.35% of the cases (1/286 fetuses), the Chlamydiaceae real-time PCR was positive. In the Chlamydiaceae-positive fetus, Chlamydia abortus was detected by a commercial microarray and 16S ribosomal RNA PCR followed by sequencing. The positive fetus had a Porcine circovirus-2 coinfection. By the Parachlamydia real-time PCR, 3.5% (10/286 fetuses of 9 abortion cases) were questionable positive (threshold cycle values: 35.0-45.0). In 2 of these 10 cases, a confirmation by Chlamydiales-specific real-time PCR was possible. All samples tested negative by the Waddlia real-time PCR. It seems unlikely that Chlamydiaceae, Parachlamydia, and Waddlia play an important role as abortigenic agents in Swiss sows.
Medicine and abortion law: complicating the reforming profession.
McGuinness, Sheelagh; Thomson, Michael
2015-01-01
The complicated intra-professional rivalries that have contributed to the current contours of abortion law and service provision have been subject to limited academic engagement. In this article, we address this gap. We examine how the competing interests of different specialisms played out in abortion law reform from the early twentieth-century, through to the enactment of the Abortion Act 1967, and the formation of the structures of abortion provision in the early 1970s. We demonstrate how professional interests significantly shaped the landscape of abortion law in England, Scotland, and Wales. Our analysis addresses two distinct and yet related fields where professional interests were negotiated or asserted in the journey to law reform. Both debates align with earlier analysis that has linked abortion law reform with the market development of the medical profession. We argue that these two axes of debate, both dominated by professional interests, interacted to help shape law's treatment of abortion, and continue to influence the provision of abortion services today. © The Author [2015].

Maintaining access to safe abortion and reducing sex ratio imbalances in Asia.
Ganatra, Bela
2008-05-01
High sex ratios at birth (108 boys to 100 girls or higher) are seen in China, Taiwan, South Korea and parts of India and Viet Nam. The imbalance is the result of son preference, accentuated by declining fertility. Prenatal sex detection with ultrasound followed by second trimester abortion is one of the ways sex selection manifests itself, but it is not the causative factor. Advocates and governments seeking to reverse this imbalance have largely prohibited sex detection tests and/or sex selective abortion, assuming these measures would reverse the trend. Such policies have been difficult to enforce and have met with only limited success. At the same time, such policies are starting to have adverse effects on the already limited access to safe and legal second trimester abortion for reasons other than sex selection. Moreover, the sex selection issue is being used as a platform for anti-abortion rhetoric by certain groups. Maintaining access to safe abortion and achieving a decline in high sex ratios are both important goals. Both are possible if the focus shifts to addressing the conditions that drive son preference.

Debate on the legalization of abortion in Zimbabwe.
1994-01-01
In Zimbabwe, where over 70,000 illegal abortions are performed each year and complications from clandestine abortion are a leading cause of maternal mortality, the abortion law debate has been re-opened. Under the present law, abortion is legal only to save the life of the mother and women who undergo illegal abortion face strict criminal sanctions. Timothy Stamps, the Minister of Health and Child Welfare, has stated, "The first rights of a child are to be desired, to be wanted, and to be planned." Dr. Illiff, of the University of Zimbabwe's Department of Obstetrics and Gynecology, has noted, "We cannot stop abortion. The choice is how safe it is." Illiff pointed out that urban Zimbabwe women run a 262 times greater risk of dying of abortion complications than their counterparts in the UK where abortion is legal. As the Women's Action Group has observed, men have dominated the current debate on abortion. The group has issued an appeal to women to enter into this debate that concerns their bodies to ensure that another law is not imposed on them. The group's appeal for action states: "We as Women's Action Group believe that every woman should decide what's right and what's wrong in her life. She and only she should be the master of her destiny. Her voice should be heard louder than anyone else's."

Full Text Available The primary aim of this study was to compare the experience of an early abortion (1st trimester to a late abortion (2nd and 3rd trimester relative to Posttraumatic Stress Disorder (PTSD symptoms after controlling for socio-demographic and personal history variables. Online surveys were completed by 374 women who experienced either a 1st trimester abortion (up to 12 weeks gestation or a 2nd or 3rd trimester abortion (13 weeks gestation or beyond. Most respondents (81% were U.S. citizens. Later abortions were associated with higher Intrusion subscale scores and with a greater likelihood of reporting disturbing dreams, reliving of the abortion, and trouble falling asleep. Reporting the pregnancy was desired by one's partner, experiencing pressure to abort, having left the partner prior to the abortion, not disclosing the abortion to the partner, and physical health concerns were more common among women who received later abortions. Social reasons for the abortion were linked with significantly higher PTSD total and subscale scores for the full sample. Women who postpone their abortions may need more active professional intervention before securing an abortion based on the increased risks identified herein. More research with diverse samples employing additional measures of mental illness is needed.

Politics, public discourse, and legislation restricting abortion has settled on a moderate orthodoxy: restrict abortion, but leave exceptions for pregnancies that result from rape and incest. I challenge that consensus and suggest it may be much harder to defend than those who support the compromise think. From both Pro-Life and Pro-Choice perspectives, there are good reasons to treat all abortions as equal. © 2015 American Society of Law, Medicine & Ethics, Inc.

About 44 million induced abortions take place worldwide annually, of which 50% are unsafe. The results of studies investigated the induced abortion rate in Iran are inconsistent. The aim of this meta-analysis was to estimate the incidence rate of induced abortion in Iran. National and international electronic databases, as well as conference databases until July 2012 were searched. Reference lists of articles were screened and the studies' authors were contacted for additional unpublished studies. Cross-sectional studies addressing induced abortion in Iran were included in this meta-analysis. The primary outcome of interest was the induced abortion rate (the number of abortions per 1000 women aged 15-44 years in a year) or the ratio (the number of abortions per 100 live births in a year). The secondary outcome of interest was the prevalence of unintended pregnancies (the number of mistimed, unplanned, or unwanted pregnancies per total pregnancies). Data were analyzed using random effect models. Of 603 retrieved studies, using search strategy, 10 studies involving 102,394 participants were eventually included in the meta-analysis. The induced abortion rate and ratio were estimated as 8.9 per 1000 women aged 15-44 years (95% CI: 5.46, 12.33) and 5.34 per 100 live births (95% CI: 3.61, 7.07), respectively. The prevalence of unintended pregnancy was estimated as 27.94 per 100 pregnant women (95% CI: 23.46, 32.42). The results of this meta-analysis helped a better understanding of the incidence of induced abortion in Iran compared to the other developing countries in Asia. However, additional sources of data on abortion other than medical records and survey studies are needed to estimate the true rate of unsafe abortion in Iran.

Full Text Available Abstract Background Improving access to safe abortion is an essential strategy in the provision of universal access to reproductive health care. Australians are largely supportive of the provision of abortion and its decriminalization. However, the lack of data and the complex legal and service delivery situation impacts upon access for women seeking an early termination of pregnancy. There are no systematic reviews from a health services perspective to help direct health planners and policy makers to improve access comprehensive medical and early surgical abortion in high income countries. This review therefore aims to identify quality studies of abortion services to provide insight into how access to services can be improved in Australia. Methods We undertook a structured search of six bibliographic databases and hand-searching to ascertain peer reviewed primary research in English between 2005 and 2015. Qualitative and quantitative study designs were deemed suitable for inclusion. A deductive content analysis methodology was employed to analyse selected manuscripts based upon a framework we developed to examine access to early abortion services. Results This review identified the dimensions of access to surgical and medical abortion at clinic or hospital-outpatient based abortion services, as well as new service delivery approaches utilising a remote telemedicine approach. A range of factors, mostly from studies in the United Kingdom and United States of America were found to facilitate improved access to abortion, in particular, flexible service delivery approaches that provide women with cost effective options and technology based services. Standards, recommendations and targets were also identified that provided services and providers with guidance regarding the quality of abortion care. Conclusions Key insights for service delivery in Australia include the: establishment of standards, provision of choice of procedure, improved provider

Medical abortion is a safe method of termination of pregnancy when performed as per guidelines with a success rate of 92-97 %. But self-administration of abortion pills is rampant throughout the country due to over the counter availability of these drugs and complications are not uncommon due to this practice. The society perceives unsupervised medical abortion as a very safe method of termination and women use this as a method of spacing. The aim of this study was to study the implications of self-administration of abortion pills by pregnant women. Retrospective observational study done in Sri Manakula Vinayagar Medical College & Hospital between the period of July 2013 to June2014. Case sheets were analysed to obtain data regarding self-administration of abortion pills and complications secondary to its administration. The following data were collected. Age, marital status, parity, duration of pregnancy as perceived by the women, confirmation of pregnancy, duration between pill intake and visit to hospital, whether any intervention done elsewhere, any known medical or surgical complications, Hb level on admission, whether patient was in shock, USG findings, evidence of sepsis, blood transfusion, treatment given and duration of hospital stay. Descriptive analysis of the collected data was done. Among the 128 cases of abortion in the study period, 40 (31.25%) patients had self-administered abortion pills. Among these 40 patients 27.5% had consumed abortion pills after the approved time period of 63 days of which 17.5% had consumed pills after 12 weeks of gestation. The most common presentation was excessive bleeding (77.5%) Severe anaemia was found in 12.5% of the patients and 5% of patients presented with shock. The outcome was as follows : 62.5% of the patients were found to have incomplete abortion, 22.5% had failed abortion and 7.5% of patients had incomplete abortion with sepsis. Surgical evacuation was performed in 67.5% of the patients whereas 12.5% of the
Pre-flight physical simulation test of HIMES reentry test vehicle
Kawaguchi, Jun'ichiro; Inatani, Yoshifumi; Yonemoto, Koichi; Hosokawa, Shigeru
ISAS is now developing a small reentry test vehicle, which is 2m long with a 1.5m wing span and weighs about 170 kg, for the purpose of exploring high angle-of-attack aerodynamic attitude control issue in supersonic and hypersonic speed. The flight test, employing 'Rockoon' launch system, is planned as a preliminary design verification for a fully reusable winged rocket named HIMES (Highly Maneuverable Experimental Space) vehicle. This paper describes the results of preflight ground test using a motion table system. This ground system test is called 'physical simulation' aimed at: (1) functional verification of side-jet system, aerodynamic surface actuators, battery and onboard avionics; and (2) guidance and control law evaluation, in total hardware-in-the-loop system. The pressure of side-jet nozzles was measured to provide exact thrust characteristics of reaction control. The dynamics of vehicle motion was calculated in real-time by the ground simulation computer.
How Danes evaluate moral claims related to abortion

OBJECTIVE: To investigate how Danish citizens evaluate four moral claims related to abortion issues, regarding the moral status of the fetus, autonomy, harm and possible negative consequences of allowing abortion and to explore the association between moral beliefs and attitudes towards abortion...... to at least one moral claim. Two hundred and fifty-eight responded to all four claims without using the option 'neither agree nor disagree' and were classified as 'morally engaged responders'. A majority of these had a pro-abortion moral. The general relationship between moral beliefs and attitudes towards...... abortion was morally sound. Being 'morally engaged' did not increase the likelihood of reaching moral judgement on whether requests for abortion should be permitted. Education, religion and parenthood were statistically associated with the investigated issues. DISCUSSION: The direction of causality...

Objective: To study the clinical differential diagnostic usefulness of dynamic determinations of serum progesterone and HCG levels in patients with abortion and ectopic pregnancy. Methods: Serum progesterone (with CLIA) and HCG (with RIA) levels were determined twice (48h apart) in 98 patients with threatened abortion, 75 patients with inevitable abortion, 52 patients with ectopic pregnancy, and 83 controls. Results: Among the three groups of patients, the serum progesterone levels were highest in the patients with threatened abortion, being significantly higher than those in the other two groups (P<0.05, P<0.01). The progesterone levels were lowest in the patients with ectopic pregnancy, being significantly less than those in other two groups (P<0.05, P<0.01). The serum HCG levels were also significantly higher in the patients with threatened abortion than those in the other two groups (P < 0.05 ), but there were no significant differences between the levels in patients with inevitable abortion and patients with ectopic pregnancy. The differences between the first and second determination HCG levels, either increased or decreased, in patients with ectopic pregnancy were significantly less than those in patients with inevitable abortion (P<0.05). Conclusion: Dynamic determination of serum progesterone and HCG levels might be of differential diagnostic help in patients with threatened abortion, inevitable abortion and ectopic pregnancy.

Induced abortion and adolescent mental health.
Stotland, Nada L
2011-10-01
Induced abortion is widely believed - by the public, healthcare professionals, and policy-makers - to lead to adverse mental health sequelae. This belief is false, as it applies both to adult women and adolescents. However, it has been used to rationalize, and been quoted in, restrictive and intrusive legislation in several states and in proposed federal legislation. It is essential for gynecologists to have accurate information, as clinicians, for their patients, and, as key experts, for policy makers. New articles concluding that there are adverse psychological outcomes from induced abortion continue to be published. The methodological flaws in these articles are so serious as to invalidate those conclusions. Several recent scholarly analyses detail these flaws. Methodologically sound studies and reviews continue to demonstrate that psychosocial problems play a role in unwanted conception and the decision to abort unwanted pregnancies but are not the result of abortion. Clinicians may have to reassure patients making decisions about their pregnancies that abortion does not cause psychiatric illness. They can do so on the basis of recent analyses substantiating that finding. (C) 2011 Lippincott Williams & Wilkins, Inc.

Full Text Available This paper describes the Flight Dynamics Automation (FDA system for COMS Flight Dynamics System (FDS and its test result in terms of the performance of the automation jobs. FDA controls the flight dynamics functions such as orbit determination, orbit prediction, event prediction, and fuel accounting. The designed FDA is independent from the specific characteristics which are defined by spacecraft manufacturer or specific satellite missions. Therefore, FDA could easily links its autonomous job control functions to any satellite mission control system with some interface modification. By adding autonomous system along with flight dynamics system, it decreases the operator’s tedious and repeated jobs but increase the usability and reliability of the system. Therefore, FDA is used to improve the completeness of whole mission control system’s quality. The FDA is applied to the real flight dynamics system of a geostationary satellite, COMS and the experimental test is performed. The experimental result shows the stability and reliability of the mission control operations through the automatic job control.
Evidence mounts for sex-selective abortion in Asia.
Westley, S B
1995-01-01
In Korea, China, and Taiwan--countries where son preference persists--the availability of prenatal screening techniques and induced abortion has produced an imbalance in the naturally occurring sex ratios of 104-107 male births for every 100 female births. Policy responses to sex-selective abortion were the focus of a 1994 International Symposium on Sex Preference for Children in the Rapidly Changing Demographic Dynamics in Asia sponsored by the United Nations Population Fund and the Government of the Republic of Korea. Modern technology (i.e., amniocentesis, ultrasound, and chorionic villi sampling) enables couples to control both family size and sex selection. According to data from the 1990 Korean Census, 80,000 female fetuses were aborted from 1986-90 as a result of son preference. In the late 1980s, the Governments of Korea, China, and India imposed bans on the use of medical technology for prenatal sex determination, but many observers maintain that regulations have served only to make the procedures clandestine and more expensive. To remedy the problems underlying sex-selective abortion, the Symposium recommended the following government actions: 1) implement policies and programs to diminish gender discrimination; 2) establish guidelines for the monitoring and regulation of prenatal testing; 3) utilize mass and folk media, interpersonal channels, and school curricula to promote gender equality; 4) strengthen the ethics curriculum of medical schools to address son preference; and 5) increase the capability of statistical and research organizations to collect gender-disaggregated data.

The objective of this study was to examine induced abortion in Côte d'Ivoire. A nationwide cross-sectional descriptive study of induced abortion was carried out in 2007 among 3,057 women aged 15-49 years. The study showed that induced abortion is a widespread practice in Côte d'Ivoire, with a prevalence estimated at 42.5%. The women who had undergone an abortion were generally under 25, unmarried, and illiterate, and had used contraception. More than half (52.1%) of all induced abortions were performed at home by traditional abortionists or were self-induced with plants or decoctions. The main reasons for induced abortion were concern about the reaction of parents (27.7%), age (22.2%), a lack of financial resources (21.3%) and the desire of women to continue their education. More than half of the participants (55.8%) stated that they had suffered complications, which were more common after a home abortion than after a hospital abortion. Political and legal measures or reforms aimed at changing abortion laws in Côte d'Ivoire and better access to family planning are required in order to prevent or treat the social issue of induced abortion.

BACKGROUND: Complications of unsafe abortion are a major contributor to maternal deaths in developing countries. This study aimed to evaluate the clinical assessment for life-threatening complications and the following management in women admitted with complications from abortions at a rural...... abortion and by trimester. Actual management was compared to the audit criteria and presented by descriptive statistics. RESULTS: Fifty six per cent of the women were in second trimester. Abortion complications were distributed as follows: 53 % incomplete abortions, 28 % threatened abortions, 12...... % inevitable abortions, 4 % missed abortions and 3 % septic abortions. Only one of 238 cases met all criteria of optimal clinical assessment and management. Thus, vital signs were measured in 3 %, antibiotic criteria was met in 59 % of the cases, intravenous fluid resuscitation was administered to 35...
Ugandan opinion-leaders' knowledge and perceptions of unsafe abortion.

While laws in Uganda surrounding abortion remain contradictory, a frequent interpretation of the law is that abortion is only allowed to save the woman's life. Nevertheless abortion occurs frequently under unsafe conditions at a rate of 54 abortions per 1000 women of reproductive age annually, taking a large toll on women's health. There are an estimated 148,500 women in Uganda who experience abortion complications annually. Understanding opinion leaders' knowledge and perceptions about unsafe abortion is critical to identifying ways to address this public health issue. We conducted in-depth, semi-structured interviews with 41 policy-makers, cultural leaders, local politicians and leaders within the health care sector in 2009-10 at the national as well as district (Bushenyi, Kamuli and Lira) level to explore their knowledge and perceptions of unsafe abortion and the potential for policy to address this issue. Only half of the sample knew the current law regulating abortion in Uganda. Respondents understood that the result of the current abortion restrictions included long-term health complications, unwanted children and maternal death. Perceived consequences of increasing access to safe abortion included improved health as well as overuse of abortion, marital conflict and less reliance on preventive behaviour. Opinion leaders expressed the most support for legalization of abortion in cases of rape when the perpetrator was unknown. Understanding opinion leaders' perspectives on this politically sensitive topic provides insight into the policy context of abortion laws, drivers behind maintaining the status quo, and ways to improve provision under the law: increase education among providers and opinion leaders.

The National Aeronautics and Space Administration (NASA) Constellation Program (CxP) has identified a series of tests to provide insight into the design and development of the Crew Launch Vehicle (CLV) and Crew Exploration Vehicle (CEV). Ares I-X was selected as the first suborbital development flight test to help meet CxP objectives. The Ares I-X flight test vehicle (FTV) is an early operational model of CLV, with specific emphasis on CLV and ground operation characteristics necessary to meet Ares I-X flight test objectives. The in-flight part of the test includes a trajectory to simulate maximum dynamic pressure during flight and perform a stage separation of the Upper Stage Simulator (USS) from the First Stage (FS). The in-flight test also includes recovery of the FS. The random vibration response from the ARES 1-X flight will be reconstructed for a few specific locations that were instrumented with accelerometers. This recorded data will be helpful in validating and refining vibration prediction tools and methodology. Measured vibroacoustic environments associated with lift off and ascent phases of the Ares I-X mission will be compared with pre-flight vibration predictions. The measured flight data was given as time histories which will be converted into power spectral density plots for comparison with the maximum predicted environments. The maximum predicted environments are documented in the Vibroacoustics and Shock Environment Data Book, AI1-SYS-ACOv4.10 Vibration predictions made using statistical energy analysis (SEA) VAOne computer program will also be incorporated in the comparisons. Ascent and lift off measured acoustics will also be compared to predictions to assess whether any discrepancies between the predicted vibration levels and measured vibration levels are attributable to inaccurate acoustic predictions. These comparisons will also be helpful in assessing whether adjustments to prediction methodologies are needed to improve agreement between the

The bovine abortion surveillance system in France aims to detect as early as possible any resurgence of bovine brucellosis, a disease of which the country has been declared free since 2005. It relies on the mandatory notification and testing of each aborting cow, but under-reporting is high. This research uses a new and simple approach which considers the calving interval (CI) as a "diagnostic test" to determine optimal cut-off point c and estimate diagnostic performance of the CI to identify aborting cows, and herds with multiple abortions (i.e. three or more aborting cows per calving season). The period between two artificial inseminations (AI) was considered as a "gold standard". During the 2006-2010 calving seasons, the mean optimal CI cut-off point for identifying aborting cows was 691 days for dairy cows and 703 days for beef cows. Depending on the calving season, production type and scale at which c was computed (individual or herd), the average sensitivity of the CI varied from 42.6% to 64.4%; its average specificity from 96.7% to 99.7%; its average positive predictive value from 27.6% to 65.4%; and its average negative predictive value from 98.7% to 99.8%. When applied to the French bovine population as a whole, this indicator identified 2-3% of cows suspected to have aborted, and 10-15% of herds suspected of multiple abortions. The optimal cut-off point and CI performance were consistent over calving seasons. By applying an optimal CI cut-off point to the cattle demographics database, it becomes possible to identify herds with multiple abortions, carry out retrospective investigations to find the cause of these abortions and monitor a posteriori compliance of farmers with their obligation to report abortions for brucellosis surveillance needs. Therefore, the CI could be used as an indicator of abortions to help improve the current mandatory notification surveillance system. Copyright © 2015 Elsevier B.V. All rights reserved.

Historically, sexual assault is a common issue in Turkey. As doctors are one of the steps to help sexually assaulted women, medical students should have basic knowledge of and sensitivity regarding this subject. Another common women's public health issue is induced abortion. In countries where access to abortion is restricted, there is a tendency towards unhealthy abortion. The aims of this study are: (1) to determine the attitudes and opinions of Marmara University Medical Faculty students about sexual assault against women and induced abortion and (2) to propose an educational program for medical students about sexual assault and abortion. Cross-sectional study. The questionnaires were self-administered and the data were analyzed using SPSS v.15.0. First, the descriptive statistics were analyzed, followed by Chi-square for contingency tests assessing differences in attitudes toward sexual assault and induced abortion by factors such as gender and educational term. Differences were considered statistically significant at p0.05). Although there was no significant difference regarding the extent of punishment by victim's status as a virgin, 21.3% (n=63) agreed that punishment should be more severe when the victim was a virgin. About 40.7% (n=120) agreed that the legal period of abortion in Turkey (10 weeks) should be longer. The majority (86.1%, n=255) agreed that legally prohibiting abortions causes an increase in unhealthy abortions. An educational program on these issues should be developed for medical students.

Abortions in cattle have a significant economic impact on animal husbandry and require prompt diagnosis for surveillance of epizootic infectious agents. Since most abortions are not epizootic but sporadic with often undetected etiologies, this study examined the bacterial community present in the placenta (PL, n = 32) and fetal abomasal content (AC, n = 49) in 64 cases of bovine abortion by next generation sequencing (NGS) of the 16S rRNA gene. The PL and AC from three fetuses of dams that died from non-infectious reasons were included as controls. All samples were analyzed by bacterial culture, and 17 were examined by histopathology. We observed 922 OTUs overall and 267 taxa at the genus level. No detectable bacterial DNA was present in the control samples. The microbial profiles of the PL and AC differed significantly, both in their composition (PERMANOVA), species richness and Chao-1 (Mann-Whitney test). In both organs, Pseudomonas was the most abundant genus. The combination of NGS and culture identified opportunistic pathogens of interest in placentas with lesions, such as Vibrio metschnikovii, Streptococcus uberis, Lactococcus lactis and Escherichia coli. In placentas with lesions where culturing was unsuccessful, Pseudomonas and unidentified Aeromonadaceae were identified by NGS displaying high number of reads. Three cases with multiple possible etiologies and placentas presenting lesions were detected by NGS. Amplicon sequencing has the potential to uncover unknown etiological agents. These new insights on cattle abortion extend our focus to previously understudied opportunistic abortive bacteria.
The triviality of abortion in Greece.
Naziri, D
1991-09-01
In Greece modern contraceptive methods are used only in a very limited manner and abortion is the primary form of birth control. There are several social and psychological issues that are considered to be responsible. A 1985 study done for the Family Planning Center of Thessaloniki found that the ratio of live births is 1.3 and the ratio of abortion is 1.8/woman. 88% of women in the study had had an abortion while practicing coitus interruptus. 90% of the women never bought condoms. In a 1989 study only 6% of women had a positive attitude about condoms. Abortion is used as the primary method of birth control regardless of a woman's socioeconomic status. Further it was found that abortion did not correlate with other modern attitudes or the emancipation of women. The decision to abort was related to difficulties and constraints inherent in bring up a child. However positive attitudes toward contraception were related to educational and occupational levels. To complicate matters the information concerning contraceptives was problematic and related to the women's own lack of initiative to find out, and a lack of correct information offered from gynecologists. A 1990 study on knowledge, attitudes, beliefs and practices in relation to HIV infection indicated that the most favored method of contraception was condoms, but 60.8% of the men reported use versus 33.7% of the women. However these figures are not very representative because the survey was given in the context of HIV prevention and no attempt was made to distinguish between regular and irregular use patterns. Abortions is not a moral issue in Greece. It was legalized in 1986 only because it came to the attention of the government that the previous prohibition was being completely ignored. Abortion is strongly affected by social and psychological factors that are complex and result from cultural view points about fertility, maternal value, and life itself that are unique to the Greek culture.

Controversy exists over psychological risks associated with abortion. The objectives of this study were to examine women's emotions, evaluations, and mental health after an abortion, as well as changes over time in these responses and their predictors. Women arriving at 1 of 3 sites for an abortion of a first-trimester unintended pregnancy were randomly approached to participate in a longitudinal study with 4 assessments-1 hour before the abortion, and 1 hour, 1 month, and 2 years after the abortion. Eight hundred eighty-two (85%) of 1043 eligible women approached agreed; 442 (50%) of 882 were followed for 2 years. Preabortion and postabortion depression and self-esteem, postabortion emotions, decision satisfaction, perceived harm and benefit, and posttraumatic stress disorder were assessed. Demographic variables and prior mental health were examined as predictors of postabortion psychological responses. Two years postabortion, 301 (72%) of 418 women were satisfied with their decision; 306 (69%) of 441 said they would have the abortion again; 315 (72%) of 440 reported more benefit than harm from their abortion; and 308 (80%) of 386 were not depressed. Six (1%) of 442 reported posttraumatic stress disorder. Depression decreased and self-esteem increased from preabortion to postabortion, but negative emotions increased and decision satisfaction decreased over time. Prepregnancy history of depression was a risk factor for depression, lower self-esteem, and more negative abortion-specific outcomes 2 years postabortion. Younger age and having more children preabortion also predicted more negative abortion evaluations. Most women do not experience psychological problems or regret their abortion 2 years postabortion, but some do. Those who do tend to be women with a prior history of depression.
Abortion denied--outcome of mothers and babies.
Del Campo, C
1984-02-15
A consistent argument favoring therapeutic abortions has been that mothers who are denied abortions will seek "illegal" help elsewhere, often in less than optimal conditions. Yet, a review of published reports on women who had been denied abortion and were followed up shows that 70.67% of the 6298 women completed their pregnancies and only 13.2% had an abortion elsewhere. Several studies have shown that the incidence of Complications of pregnancy is no greater in mothers denied abortion than in paired controls. The results of a prospective study by Laukaran and Van Den Berg showed a higher incidence of maternal accidental injury, a borderline increase of maternal accidental injury, a borderline increase in the prevalence of congenital anomalies, and a higher incidence of infection and hemorrhage during the puerperium in women who had been denied abortion. They concluded that maternal attitude and psychosocial stress had little effect on the progress of the pregnancy and labor. Published reports on the psychological effects on the children of women who had been denied abortion are few, mainly because longterm follow-up is required. In 1966 Forssman and Thuwe described the results of their study of 120 children whose mothers had been denied abortion. The children had been followed up until their 21st birthdays. The controls had been carefully paired. The proportion of children who had been placed in foster and children's homes was significantly higher among the "unwanted" children than among the controls (50% versus 18%). There was no statistically significant difference in the rates of drunken misconduct, crime, or "educational mental subnormality" between the 2 groups, but the incidence rates of delinquency and psychiatric consultation were 10% and 13% higher respectively among the unwanted children than among the controls. There have been virtually no objective studies on the psychologic and social well-being of women who have been denied abortion. The literature

Method:From June to December 2011,a total of 180 cases of induced abortion women(100 cases of painless artificial abortion and 80 cases of traditional abortion)in the hospital maternity line were selected and followed up one year. The investigation related to whether there was a repeat abortion,both before and after the abortion mental state. Result:Repeat abortion rate of previous painless artificial abortion group was significantly higher than that of the traditional artificial abortion group(P<0.05),significant difference existed before and after six months of repeated abortion and two abortion mental state. Conclusion:Although induced abortion surgery pain problems for women,but duplicate after the higher abortion rate,the emphasis on quality abortion family planning services should focus on postoperative induced abortion initiative education,face-to-face consultation,and provide supporting information,free contraceptives,and the requirements of the male partner to

BACKGROUND: Few studies have examined smoking prior to pregnancy and the occurrence of spontaneous abortion, as most studies have addressed the risk of spontaneous abortion in relation to smoking during pregnancy. However, results are not entirely consistent. The aim of the present study...... was to assess the risk of spontaneous abortion considering smoking prior to pregnancy. METHODS: We performed a nested case-control study using prospective data from a population-based cohort comprising 11,088 women aged 20-29 years. From this cohort, women who experienced either a spontaneous abortion (n=343......) or who gave birth (n=1,578) during follow-up were selected. Associations between self-reported smoking at enrollment and subsequent spontaneous abortion were analyzed by means of multiple logistic regression. RESULTS: The risk of spontaneous abortion in relation to pre-pregnancy smoking showed a clear...

The Crew Exploration Vehicle (CEV) is required to maintain continuous abort capability from lift off through destination arrival. This requirement is driven by the desire to provide the capability to safely return the crew to Earth after failure scenarios during the various phases of the mission. This paper addresses abort trajectory design considerations, concept of operations and guidance algorithm prototypes for the portion of the ascent trajectory following nominal jettison of the Launch Abort System (LAS) until safe orbit insertion. Factors such as abort system performance, crew load limits, natural environments, crew recovery, and vehicle element disposal were investigated to determine how to achieve continuous vehicle abort capability.

The Station Explorer for X-ray Timing and Navigation Technology (SEXTANT) is a technology demonstration enhancement to the Neutron-star Interior Composition Explorer (NICER) mission. NICER is a NASA Explorer Mission of Opportunity that will be hosted on the International Space Station (ISS). SEXTANT will, for the first time, demonstrate real-time, on-board X-ray Pulsar Navigation (XNAV), a significant milestone in the quest to establish a GPS-like navigation capability available throughout our Solar System and beyond. This paper gives an overview of the SEXTANT system architecture and describes progress prior to environmental testing of the NICER flight instrument. It provides descriptions and development status of the SEXTANT flight software and ground system, as well as detailed description and results from the flight software functional and performance testing within the high-fidelity Goddard Space Flight Center (GSFC) X-ray Navigation Laboratory Testbed (GXLT) software and hardware simulation environment. Hardware-in-the-loop simulation results are presented, using the engineering model of the NICER timing electronics and the GXLT pulsar simulator-the GXLT precisely controls NASA GSFC's unique Modulated X-ray Source to produce X-rays that make the NICER detector electronics appear as if they were aboard the ISS viewing a sequence of millisecond pulsars

the maternal age at child birth is increasing. If induced abortion is an important means of postponing childbirth in a population, it is to be expected that in young women the rate of conceived pregnancies is stable over time, but the induced abortion rate is increasing. We studied birth rates, induced abortion rates and the sum of these rates by maternal age during four decades. register-based study. all women 15-49 years living in Norway. we present temporal changes in birth rates and induced abortion rates within age groups during the period 1979-2007. We also estimated the sum rate of births and induced abortions. Data were obtained from national statistics. live births and induced abortions per 1000 women per year. the induced abortion rates have been relatively stable within age groups, except for a decrease in women 15-19 years (from 24.2 in 1979 to 17.0 in 2007) and an increase in women 20-24 years (from 23.2 to 29.5). The birth rates however, have decreased dramatically in women 20-24 years old (from 113.6 to 60.5). Hence, the sum rate of births and induced abortions in women 20-24 years old has decreased from 136.8 to 90.0. In women 30 years old or older, the birth rates have increased. the induced abortion rate has been relatively stable in all age groups over time, suggesting a limited influence of induced abortions on the postponement of childbearing.
Induced abortion amongst undergradute students of University of Port Harcourt.

Induced abortion is the termination of pregnancy through a deliberate intervention intended to end the pregnancy. This practice is widespread in Nigeria despite the restrictive abortion laws in Nigeria. Many women still undergo induced abortion every year and endanger their health and lives as induced abortion can only be procured illegally in Nigeria. We hope to determine the proportion of undergraduate students who had induced abortion in the past and the contributing factors. To determine the proportion of the undergraduate students who support the restrictive abortion laws in Nigeria. A cross sectional questionnaire survey of undergraduate students of the University of Port Harcourt was done through a cluster sampling method along with focus group discussion with some of the respondents. 451 out of 500 administered questionnaires were retrieved and analyzed. The incidence of induced abortion amongst the respondents was 47.2%. About 40% had never used an effective form of contraception in the past and 13% were unaware of contraception. 77.9% of the induced abortion was by dilation and curettage and 1% by manual vacuum aspiration. Up to two third of the respondents were against legalization of abortion. Up to 47% of these undergraduates had performed abortion in the past. Protecting educational career was the single most important reason for this. Although most of these undergraduates are against legalizing abortion, they highly patronize unsafe abortion. Improving contraceptive awareness and usage will reduce unwanted pregnancy and induced abortion. This option appears next to total abstinence in reducing the morbidity and mortality from induced abortion in this country.

In settings where abortion is legally restricted, or permitted but not widely accessible, women face significant barriers to abortion access, sometimes leading them to seek services outside legal facilities. The advent of medication abortion has further increased the prevalence of informal sector abortion. This study investigates the reasons for attempting self-induction, methods used, complications, and sources of information about informal sector abortion, and tests a specific recruitment method which could lead to improved estimates of informal sector abortion prevalence among an at-risk population. We recruited women who have sought informal sector abortion services in Cape Town, South Africa using respondent driven sampling (RDS). An initial seed recruiter was responsible for initiating recruitment using a structured coupon system. Participants completed face-to-face questionnaires, which included information about demographics, informal sector abortion seeking, and safe abortion access needs. We enrolled 42 women, nearly one-third of whom reported they were sex workers. Thirty-four women (81%) reported having had one informal sector abortion within the past 5 years, 14% reported having had two, and 5% reported having had three. These women consumed home remedies, herbal mixtures from traditional healers, or tablets from an unregistered provider. Twelve sought additional care for potential warning signs of complications. Privacy and fear of mistreatment at public sector facilities were among the main reported reasons for attempting informal sector abortion. Most women (67%) cited other community members as their source of information about informal sector abortion; posted signs and fliers in public spaces also served as an important source of information. Women are attempting informal sector abortion because they seek privacy and fear mistreatment and stigma in health facilities. Some were unaware how or where to seek formal sector services, or believed the

Threshold Assessment of Gear Diagnostic Tools on Flight and Test Rig Data
Dempsey, Paula J.; Mosher, Marianne; Huff, Edward M.
2003-01-01
A method for defining thresholds for vibration-based algorithms that provides the minimum number of false alarms while maintaining sensitivity to gear damage was developed. This analysis focused on two vibration based gear damage detection algorithms, FM4 and MSA. This method was developed using vibration data collected during surface fatigue tests performed in a spur gearbox rig. The thresholds were defined based on damage progression during tests with damage. The thresholds false alarm rates were then evaluated on spur gear tests without damage. Next, the same thresholds were applied to flight data from an OH-58 helicopter transmission. Results showed that thresholds defined in test rigs can be used to define thresholds in flight to correctly classify the transmission operation as normal.

Background Induced abortion is one of the greatest human rights dilemmas of our time. Yet, abortion is a very common experience in every culture and society. According to the World Health Organization, Ethiopia had the fifth largest number of maternal deaths in 2005 and unsafe abortion was estimated to account for 32% of all maternal deaths in Ethiopia. Youth are disproportionately affected by the consequences of unsafe abortion. The objective of this study was, therefore, to determine the magnitude and identify factors associated with abortion among female Wolaita Sodo University students. Methods A descriptive, cross-sectional study was conducted in Wolaita Sodo University between May and June 2011. Data were collected from 493 randomly selected female students using structured and pre-tested questionnaires. Results The rate of abortion among students was found to be 65 per 1000 women, making it three fold the national rate of abortion for Ethiopia (23/1000 women aged 15–44). Virtually all of the abortions (96.9%) were induced and only half (16) were reported to be safe. Students with history of alcohol use, who are first-year and those enrolled in faculties with no post-Grade 10 Natural Science background had higher risk of abortion than their counterparts. About 23.7% reported sexual experience. Less than half of the respondents (44%) ever heard of emergency contraception and only 35.9% of those who are sexually experienced ever used condom. Conclusions High rate of abortion was detected among female Wolaita Sodo University students and half of the abortions took place/initiated under unsafe circumstances. Knowledge of students on legal and safe abortion services was found to be considerably poor. It is imperative that improved sexual health education, with focus on safe and legal abortion services is rendered and wider availability of Youth Friendly family planning services are realized in Universities and other places where young men and women congregate

The Lightning Imaging Sensor (LIS) is one of the components onboard the Tropical Rainfall Measuring Mission (TRMM) satellite, and was designed to detect and locate lightning over the tropics. The LIS flight code was developed to run on a single onboard digital signal processor, and has operated the LIS instrument since 1997 when the TRMM satellite was launched. The software provides controller functions to the LIS Real-Time Event Processor (RTEP) and onboard heaters, collects the lightning event data from the RTEP, compresses and formats the data for downlink to the satellite, collects housekeeping data and formats the data for downlink to the satellite, provides command processing and interface to the spacecraft communications and data bus, and provides watchdog functions for error detection. The Special Test Equipment (STE) software was designed to operate specific test equipment used to support the LIS hardware through development, calibration, qualification, and integration with the TRMM spacecraft. The STE software provides the capability to control instrument activation, commanding (including both data formatting and user interfacing), data collection, decompression, and display and image simulation. The LIS STE code was developed for the DOS operating system in the C programming language. Because of the many unique data formats implemented by the flight instrument, the STE software was required to comprehend the same formats, and translate them for the test operator. The hardware interfaces to the LIS instrument using both commercial and custom computer boards, requiring that the STE code integrate this variety into a working system. In addition, the requirement to provide RTEP test capability dictated the need to provide simulations of background image data with short-duration lightning transients superimposed. This led to the development of unique code used to control the location, intensity, and variation above background for simulated lightning strikes

The 2005 expansion of the Ethiopian abortion law provided minors access to legal abortions, yet little is known about abortion among adolescents. This paper estimates the incidence of legal and clandestine abortions and the severity of abortion-related complications among adolescent and nonadolescent women in Ethiopia in 2014. This paper uses data from three surveys: a Health Facility Survey (n = 822) to collect data on legal abortions and postabortion complications, a Health Professionals Survey (n = 82) to estimate the share of clandestine abortions that resulted in treated complications, and a Prospective Data Survey (n = 5,604) to collect data on abortion care clients. An age-specific variant of the Abortion Incidence Complications Method was used to estimate abortions by age-group. Adolescents have the lowest abortion rate among all women below age 35 (19.6 per 1,000 women). After adjusting for lower levels of sexual activity among adolescents however, we find that adolescents have the highest abortion rate among all age-groups. Adolescents also have the highest proportion (64%) of legal abortions compared with other age-groups. We find no differences in the severity of abortion-related complications between adolescent and nonadolescent women. We find no evidence that adolescents are more likely than older women to have clandestine abortions. However, the higher abortion and pregnancy rates among sexually active adolescents suggest that they face barriers in access to and use of contraceptive services. Further work is needed to address the persistence of clandestine abortions among adolescents in a context where safe and legal abortion is available.

Maternal underweight and the risk of spontaneous abortion
DEFF Research Database (Denmark)
Helgstrand, Stine; Andersen, Anne-Marie Nybo

BACKGROUND: To evaluate the risk of spontaneous abortion in relation to maternal pre-pregnant underweight. METHODS: The study was designed as a cohort study within the framework of the Danish National Birth Cohort (DNBC). The participants were a total of 23 821 women recruited consecutively...... spontaneous abortion. Relative risk of spontaneous abortion was calculated as Hazard Ratios using Cox regression with delayed entry. RESULTS: The outcome measure was spontaneous abortion. The hazard ratio for spontaneous abortion in women with a pre-pregnant body mass index (BMI) below 18.5 was 1.24 (95......% confidence limits 0.95-1.63) compared to women with pre-pregnant BMI 18.5-24.9. Women with a BMI of 25 or more had a smaller increase in risk of spontaneous abortion. Adjustment for maternal age, parity, previous miscarriages, and lifestyle factors did not affect the estimates substantially, neither did...

Diagnostic findings in 218 aborted bovine foetuses are reported. The materials were examined in a matched case-control study of 69 Danish dairy herds with a sudden increase in the number of abortions and a corresponding 69 control herds. Foetuses aborted during the subsequent 6-month period were...... examined to identify the cause of abortion if possible. A total of 186 specimens were submitted from case herds and 32 from control herds. A likely cause of abortion was diagnosed in 73 foetuses. The most common cause was bovine viral diarrhoea virus (BVDV: 13%) followed by Neospora caninum infection (10......%), mycosis (5%) and Bacillus licheniformis infection (4%). Foetal and/or placental lesions were found in a further 27 cases. Only BVDV infection and neosporosis were diagnosed in more than one foetus per herd and only protozoal associated abortions occurred significantly more frequently in the case, rather...
Psychosocial factors and pre-abortion psychological health: The significance of stigma.
Steinberg, Julia R; Tschann, Jeanne M; Furgerson, Dorothy; Harper, Cynthia C
2016-02-01
Most research in mental health and abortion has examined factors associated with post-abortion psychological health. However, research that follows women from before to after their abortion consistently finds that depressive, anxiety, and stress symptoms are highest just before an abortion compared to any time afterwards. This finding suggests that studies investigating psychosocial factors related to pre-abortion mental health are warranted. The current study uses data from 353 women seeking abortions at three community reproductive health clinics to examine predictors of pre-abortion psychological health. Drawing from three perspectives in the abortion and mental health literature, common risks, stress and coping, and sociocultural context, we conducted multivariable analyses to examine the contribution of important factors on depressive, anxiety, and stress symptoms just before an abortion, including sociodemographics, abortion characteristics, childhood adversities, recent adversities with an intimate partner, relationship context, future pregnancy desires, and perceived abortion stigma. Childhood and partner adversities, including reproductive coercion, were associated with negative mental health symptoms, as was perceived abortion stigma. Before perceived abortion stigma was entered into the model, 18.6%, 20.7%, and 16.8% of the variance in depressive, anxiety, and stress symptoms respectively, was explained. Perceived abortion stigma explained an additional 13.2%, 9.7%, and 10.7% of the variance in depressive, anxiety, and stress symptoms pre-abortion. This study, one of the first to focus on pre-abortion mental health as an outcome, suggests that addressing stigma among women seeking abortions may significantly lower their psychological distress.

To investigate predictable ultrasonographic findings of early abortion. To investigate objective rules for the screening of abortion. Ultrasonographic examination of 111 early pregnancies between the sixth and ninth week in women who had regular 28 day menstrual cycles was performed. Ultrasonographic measurements of the gestational sac, crown rump length and fetal heart rate were performed using a linear array real time transducer with doppler ultrasonogram. All measurements of 17 early abortions were compared to those of 94 normal pregnancies. Most of early aborted pregnancies were classified correctly by discriminant analysis with G-SAC and CRL (G-SAC=0.5 CRL + 15, sensitivity 76.5%, specificity 96.8%). With the addition of FHR, 94.1% of early abortions could be predicted. In conclusion, ultrasonographic findings of early intrauterine growth retardation, small gestational sac and bradycardia can be predictable signs suggestive of poor prognosis of early pregnancies
Quantitative and qualitative assessment of the bovine abortion surveillance system in France.
Bronner, Anne; Gay, Emilie; Fortané, Nicolas; Palussière, Mathilde; Hendrikx, Pascal; Hénaux, Viviane; Calavas, Didier
2015-06-01
Bovine abortion is the main clinical sign of bovine brucellosis, a disease of which France has been declared officially free since 2005. To ensure the early detection of any brucellosis outbreak, event-driven surveillance relies on the mandatory notification of bovine abortions and the brucellosis testing of aborting cows. However, the under-reporting of abortions appears frequent. Our objectives were to assess the aptitude of the bovine abortion surveillance system to detect each and every bovine abortion and to identify factors influencing the system's effectiveness. We evaluated five attributes defined by the U.S. Centers for Disease Control with a method suited to each attribute: (1) data quality was studied quantitatively and qualitatively, as this factor considerably influences data analysis and results; (2) sensitivity and representativeness were estimated using a unilist capture-recapture approach to quantify the surveillance system's effectiveness; (3) acceptability and simplicity were studied through qualitative interviews of actors in the field, given that the surveillance system relies heavily on abortion notifications by farmers and veterinarians. Our analysis showed that (1) data quality was generally satisfactory even though some errors might be due to actors' lack of awareness of the need to collect accurate data; (2) from 2006 to 2011, the mean annual sensitivity - i.e. the proportion of farmers who reported at least one abortion out of all those who detected such events - was around 34%, but was significantly higher in dairy than beef cattle herds (highlighting a lack of representativeness); (3) overall, the system's low sensitivity was related to its low acceptability and lack of simplicity. This study showed that, in contrast to policy-makers, most farmers and veterinarians perceived the risk of a brucellosis outbreak as negligible. They did not consider sporadic abortions as a suspected case of brucellosis and usually reported abortions only to
Kodak Mirror Assembly Tested at Marshall Space Flight Center

This photo (a frontal view) is of one of many segments of the Eastman-Kodak mirror assembly being tested for the James Webb Space Telescope (JWST) project at the X-Ray Calibration Facility at Marshall Space Flight Center (MSFC). MSFC is supporting Goddard Space Flight Center (GSFC) in developing the JWST by taking numerous measurements to predict its future performance. The tests are conducted in a vacuum chamber cooled to approximate the super cold temperatures found in space. During its 27 years of operation, the facility has performed testing in support of a wide array of projects, including the Hubble Space Telescope (HST), Solar A, Chandra technology development, Chandra High Resolution Mirror Assembly and science instruments, Constellation X-Ray Mission, and Solar X-Ray Imager, currently operating on a Geostationary Operational Environment Satellite. The JWST is NASA's next generation space telescope, a successor to the Hubble Space Telescope, named in honor of NASA's second administrator, James E. Webb. It is scheduled for launch in 2010 aboard an expendable launch vehicle. It will take about 3 months for the spacecraft to reach its destination, an orbit of 940,000 miles in space.
From abortion to contraception: Tbilisi, 1990.
David, H P
1991-01-01
Hoping to provide women other choice besides abortion as a way to regulate fertility, 220 experts from 27 mostly European countries met in Tbilisi, Georgia, USSR to discuss ways of increasing access to modern contraceptives. Held last October, the conference was sponsored by the United Nations Population Fund (UNFPA), the World Health Organization European Regional Office (WHO/EURO), the International Planned Parenthood Federation/Europe, and the Zhordania Institute of Human Reproduction, Tbilisi. The meeting produced the Tbilisi Declaration, which -- among other things -- recognizes that unwanted pregnancies and unsafe abortions pose a serious health and social problem. Criminalization, the experts agreed, does little to reduce the number of abortions, and only increases the number of unsafe operations. The Tbilisi Declaration also affirms women's right to decide freely on the number and spacing of children, their right to reproductive health, their right to self-determination in their sexual and reproductive lives, and the right of every child to be a wanted child. The participants addressed the high incidents of abortion in some European countries -- particularly the Soviet Union. With the highest rate of abortion in Europe, the Soviet Union recorded 6 million legal abortions in 1988, and estimates that another 6 million were performed illegally. Nonetheless, perestroika has begun to facilitate access to contraceptives. Participants also discussed new methods of early pregnancy termination, RU486 and menstrual regulation procedures (MR), neither of which is readily available. Increasing access to these methods would help reduce suffering and unnecessary deaths.
Abortion law around the world: progress and pushback.
Finer, Louise; Fine, Johanna B
2013-04-01
There is a global trend toward the liberalization of abortion laws driven by women's rights, public health, and human rights advocates. This trend reflects the recognition of women's access to legal abortion services as a matter of women's rights and self-determination and an understanding of the dire public health implications of criminalizing abortion. Nonetheless, legal strategies to introduce barriers that impede access to legal abortion services, such as mandatory waiting periods, biased counseling requirements, and the unregulated practice of conscientious objection, are emerging in response to this trend. These barriers stigmatize and demean women and compromise their health. Public health evidence and human rights guarantees provide a compelling rationale for challenging abortion bans and these restrictions.

In Defending Life: A Moral and Legal Case Against Abortion Choice (2007) and an earlier article in this journal, "Defending Abortion Philosophically"(2006), Francis Beckwith argues that fetuses are, from conception, prima facie wrong to kill. His arguments are based on what he calls a "metaphysics of the human person" known as "The Substance View." I argue that Beckwith's metaphysics does not support his abortion ethic: Moral, not metaphysical, claims that are part of this Substance View are the foundation of the argument, and Beckwith inadequately defends these moral claims. Thus, Beckwith's arguments do not provide strong support for what he calls the "pro-life" view of abortion.

Background Concern has been expressed about potential harm to women's mental health in association with having an induced abortion, but it remains unclear whether induced abortion is associated with an increased risk of subsequent psychiatric problems. Methods We conducted a population-based cohort......-trimester induced abortion or a first childbirth during that period.

Nation's Capital to cover low-income women's abortions.
1994-04-15
Sharon Pratt Kelly, the mayor of the District of Columbia, has announced that, effective May 1, 1994, the city will use its Medical Charities Fund to pay for "medically appropriate" abortions for women with annual incomes of US$13,200 who do not have health insurance that covers abortions. This income level represents 185% of the federal poverty level for single women. The determination as to whether an abortion is "appropriate" will be made by the woman's physician. From 1989-93, there was a ban on the use of District of Columbia tax monies to cover abortions for local women. In 1988, however, approximately 4000 District women received funding for their abortions. The US$1 million Medical Charities Fund was originally set up to cover emergency room bills for low-income District residents who did not qualify for Medicaid. $650,000 is expected to be added to the fund; in addition, the District's 1995 budget will allocate funding earmarked for abortion coverage for low-income women.
Population Policy: Abortion and Modern Contraception Are Substitutes.
Miller, Grant; Valente, Christine
2016-08-01
A longstanding debate exists in population policy about the relationship between modern contraception and abortion. Although theory predicts that they should be substitutes, the empirical evidence is difficult to interpret. What is required is a large-scale intervention that alters the supply (or full price) of one or the other and, importantly, that does so in isolation (reproductive health programs often bundle primary health care and family planning-and in some instances, abortion services). In this article, we study Nepal's 2004 legalization of abortion provision and subsequent expansion of abortion services, an unusual and rapidly implemented policy meeting these requirements. Using four waves of rich individual-level data representative of fertile-age Nepalese women, we find robust evidence of substitution between modern contraception and abortion. This finding has important implications for public policy and foreign aid, suggesting that an effective strategy for reducing expensive and potentially unsafe abortions may be to expand the supply of modern contraceptives.
Induced first-trimester abortion and risk of mental disorder.

Concern has been expressed about potential harm to women's mental health in association with having an induced abortion, but it remains unclear whether induced abortion is associated with an increased risk of subsequent psychiatric problems. We conducted a population-based cohort study that involved linking information from the Danish Civil Registration system to the Danish Psychiatric Central Register and the Danish National Register of Patients. The information consisted of data for girls and women with no record of mental disorders during the 1995-2007 period who had a first-trimester induced abortion or a first childbirth during that period. We estimated the rates of first-time psychiatric contact (an inpatient admission or outpatient visit) for any type of mental disorder within the 12 months after the abortion or childbirth as compared with the 9-month period preceding the event. The incidence rates of first psychiatric contact per 1000 person-years among girls and women who had a first abortion were 14.6 (95% confidence interval [CI], 13.7 to 15.6) before abortion and 15.2 (95% CI, 14.4 to 16.1) after abortion. The corresponding rates among girls and women who had a first childbirth were 3.9 (95% CI, 3.7 to 4.2) before delivery and 6.7 (95% CI, 6.4 to 7.0) post partum. The relative risk of a psychiatric contact did not differ significantly after abortion as compared with before abortion (P = 0.19) but did increase after childbirth as compared with before childbirth (P abortion does not support the hypothesis that there is an increased risk of mental disorders after a first-trimester induced abortion.

[History of induced abortion in Denmark from 1200 to 1979].
Manniche, E
1982-10-01
History of induced abortion in Denmark from 1200 to 1979 is reviewed. The 1st Danish law of 1200 did not touch upon the question of induced abortion. From the beginning of the 13th century to Religious Reformation in 1536, Roman Catholic law influenced every aspect of Danish life including induced abortion. In 1683 in King Christian V's constitution called Dansk Lov induced abortion was discussed. Immoral women who aborted fetuses or killed newborn babies were decapitated. In Copenhagen in the years 1624-1632 and 1638-1663 17 women were executed because of induced abortion or murder of newborn babies. Although Dansk Lov was effective till 1866, Danish kings came to treat female criminals less severely since about 1780-1800. For example, between 1855 and 1866 42 women convicted of murder of newborn babies or abortion were given pardon (12 years of imprisonment instead of life sentence). In 1866, abortion and murder of babies were treated separately in the Danish criminal law. Induced abortion meant up to 8 years of imprisonment and labor. In 1930 life sentence was abolished; induced abortion called for only up to 2 years of imprisonment, while those who assisted for money were punished more severely (up to 8 years in prison). In 1937 the Danes legalized induced abortion for medical, ethical, (e.g. rape case) and eugenic reasons. By 1973 legalized abortion was available, free of charge, to every Danish female resident within 12 weeks of pregnancy. In 1980 abortion rate was about 41% of total births. It is estimated 2/3 of Danish women experience abortion. Lastly, illegitimate births and miscarriages are on the rise due to changes in women's social status and role.

Induced abortion among Brazilian female sex workers: a qualitative study.
Madeiro, Alberto Pereira; Diniz, Debora
2015-02-01
Prostitutes are vulnerable to unplanned pregnancies and abortions. In Brazil, abortion is a crime and there is no data about unsafe abortions for this population. The study describes how prostitutes perform illegal abortions and the health consequences thereof. Semi-structured interviews with 39 prostitutes from three cities in Brazil with previous induced abortion experience were conducted. Sixty-six abortions, with between one and eight occurrences per woman, were recorded. The majority of the cases resulted from sexual activity with clients. The inconsistent use of condoms with regular clients and the consumption of alcohol during work were indicated as the main causes of unplanned pregnancies. The main method to perform abortion was the intravaginal and oral use of misoprostol, acquired in pharmacies or on the black market. Invasive measures were less frequently reported, however with more serious health complications. The fear of complaint to the police meant that most women do not inform the health team regarding induced abortion. The majority of prostitutes aborted with the use of illegally-acquired misoprostol, ending abortion in a public hospital with infection and hemorrhagic complications. The data indicate the need for a public policy focusing on the reproductive health of prostitutes.

The Unmanned Aircraft Systems Integration in the National Airspace System project, or UAS Integration in the NAS, aims to reduce technical barriers related to safety and operational challenges associated with enabling routine UAS access to the NAS. The UAS Integration in the NAS Project conducted a flight test activity, referred to as Flight Test 3 (FT3), involving several Detect-and-Avoid (DAA) research prototype systems between June 15, 2015 and August 12, 2015 at the Armstrong Flight Research Center (AFRC). This report documents the flight testing and analysis results for the NASA Ames-developed JADEM-Autoresolver DAA system, referred to as 'Autoresolver' herein. Four flight test days (June 17, 18, 22, and July 22) were dedicated to Autoresolver testing. The objectives of this test were as follows: 1. Validate CPA prediction accuracy and detect-and-avoid (DAA, formerly known as self-separation) alerting logic in realistic flight conditions. 2. Validate DAA trajectory model including maneuvers. 3. Evaluate TCAS/DAA interoperability. 4. Inform final Minimum Operating Performance Standards (MOPS). Flight test scenarios were designed to collect data to directly address the objectives 1-3. Objective 4, inform final MOPS, was a general objective applicable to the UAS in the NAS project as a whole, of which flight test is a subset. This report presents analysis results completed in support of the UAS in the NAS project FT3 data review conducted on October 20, 2015. Due to time constraints and, to a lesser extent, TCAS data collection issues, objective 3 was not evaluated in this analysis.

The modified BQM-34 Firebee II drone with Aeroelastic Research Wing (ARW-1), a supercritical airfoil, during a 1980 research flight. The remotely-piloted vehicle, which was air launched from NASA's NB-52B mothership, participated in the Drones for Aerodynamic and Structural Testing (DAST) program which ran from 1977 to 1983. The DAST 1 aircraft (Serial #72-1557), pictured, crashed on 12 June 1980 after its right wing ripped off during a test flight near Cuddeback Dry Lake, California. The crash occurred on the modified drone's third free flight. These are the image contact sheets for each image resolution of the NASA Dryden Drones for Aerodynamic and Structural Testing (DAST) Photo Gallery. From 1977 to 1983, the Dryden Flight Research Center, Edwards, California, (under two different names) conducted the DAST Program as a high-risk flight experiment using a ground-controlled, pilotless aircraft. Described by NASA engineers as a 'wind tunnel in the sky,' the DAST was a specially modified Teledyne-Ryan BQM-34E/F Firebee II supersonic target drone that was flown to validate theoretical predictions under actual flight conditions in a joint project with the Langley Research Center, Hampton, Virginia. The DAST Program merged advances in electronic remote control systems with advances in airplane design. Drones (remotely controlled, missile-like vehicles initially developed to serve as gunnery targets) had been deployed successfully during the Vietnamese conflict as reconnaissance aircraft. After the war, the energy crisis of the 1970s led NASA to seek new ways to cut fuel use and improve airplane efficiency. The DAST Program's drones provided an economical, fuel-conscious method for conducting in-flight experiments from a remote ground site. DAST explored the technology required to build wing structures with less than normal stiffness. This was done because stiffness requires structural weight but ensures freedom from flutter-an uncontrolled, divergent oscillation of

Orthostatic intolerance (OI) is a concern for astronauts returning from long-duration space flight. One countermeasure that has been used to protect against OI after short-duration bed rest and space flight is the use of lower body and abdominal compression garments. However, since the end of the Space Shuttle era we have not been able to test crewmembers during the first 24 hours after landing on Earth. NASA's Pilot Field Test provided us the opportunity to test cardiovascular responses of crewmembers wearing the Russian Kentavr compression garment during a stand test at multiple time points throughout the first 24 hours after landing. HYPOTHESIS We hypothesized that the Kentavr compression garment would prevent an increase in heart rate (HR) >15 bpm during a 3.5-min stand test. METHODS: The Pilot Field Test was conducted up to 3 times during the first 24 hours after crewmembers returned to Earth: (1) either in a tent adjacent to the Soyuz landing site in Kazakhstan (approx.1 hr) or after transportation to the Karaganda airport (approx. 4 hr); (2) during a refueling stop in Scotland (approx.12 hr); and (3) upon return to NASA Johnson Space Center (JSC) (approx.24 hr). We measured HR and arterial pressure (finger photoplethysmography) for 2 min while the crewmember was prone and throughout 3.5 min of quiet standing. Eleven crewmembers consented to participate; however, 2 felt too ill to start the test and 1 stopped 30 sec into the stand portion of the test. Of the remaining 8 crewmembers, 2 did not wear the Russian Kentavr compression garment. Because of inclement weather at the landing site, 5 crewmembers were flown by helicopter to the Karaganda airport before initial testing and received intravenous saline before completing the stand test. One of these crewmembers wore only the portion of the Russian Kentavr compression garment that covered the lower leg and thus lacked thigh and abdominal compression. All crewmembers continued wearing the Russian Kentavr
Airborne Turbulence Detection and Warning ACLAIM Flight Test Results

The Airborne Coherent Lidar for Advanced Inflight Measurements (ACLAIM) is a NASA/Dryden-lead program to develop and demonstrate a 2 micrometers pulsed Doppler lidar for airborne look-ahead turbulence detection and warning. Advanced warning of approaching turbulence can significantly reduce injuries to passengers and crew aboard commercial airliners. The ACLAIM instrument is a key asset to the ongoing Turbulence component of NASA's Aviation Safety Program, aimed at reducing the accident rate aboard commercial airliners by a factor of five over the next ten years and by a factor of ten over the next twenty years. As well, the advanced turbulence warning capability can prevent "unstarts" in the inlet of supersonic aircraft engines by alerting the flight control computer which then adjusts the engine to operate in a less fuel efficient, and more turbulence tolerant, mode. Initial flight tests of the ACLAIM were completed in March and April of 1998. This paper and presentation gives results from these initial flights, with validated demonstration of Doppler lidar wind turbulence detection several kilometers ahead of the aircraft.
Can stories reduce abortion stigma? Findings from a longitudinal cohort study.
Cockrill, Kate; Biggs, Antonia
2018-03-01
Women often hide or selectively disclose abortion experiences due to stigma. Secrecy can help women avoid stigma but may also result in isolation and a lack of social support and contribute to broader social silence. This study assesses whether a book-club intervention can support abortion disclosure among book club participants and improve participants' affective responses towards women who have abortions and abortion providers. A total of 109 women from 13 all-female book clubs located in 9 US states read and discussed a non-fiction book that included stories about pregnancy and abortion, participated in a book club discussion and completed baseline, immediate post-intervention and endline surveys. In 10 out of the 13 book club discussions, at least one member disclosed having had a previous abortion. Overall, 15 of the 19 women who privately reported having a previous abortion self-disclosed one or more abortions during the book club discussion. Following the book club intervention, women reported having more positive feelings toward women who have abortions and abortion providers. Greater improvement and longer lasting effects were seen in groups where there was also an in-person disclosure of abortion experience. Findings suggest that exposure to the stories of women who have had abortions can reduce abortion stigma.

Provision of safe abortion is widely recognized as vital to addressing the health and wellbeing of populations. Research on abortion is essential to meet the UN Sustainable Development Goals. Researchers in population health from university, policy, and practitioner contexts working on two multidisciplinary projects on family planning and safe abortion in Africa and Asia were brought together for a workshop to discuss the future research agenda on induced abortion. Research on care-seeking behavior, supply of abortion care services, and the global and national policy context will help improve access to and experiences of safe abortion services. A number of areas have potential in designing intervention strategies, including clinical innovations, quality improvement mechanisms, community involvement, and task sharing. Research on specific groups, including adolescents and young people, men, populations affected by conflict, marginalized groups, and providers could increase understanding of provision, access to and experiences of induced abortion. Methodological and conceptual advances, for example in the measurement of induced abortion incidence, complications, and client satisfaction, conceptualizations of induced abortion access and care, and methods for follow-up of patients who have induced abortions, will improve the accuracy of measurements of induced abortion, and add to understanding of women's experiences of induced abortions and abortion care. © 2018 International Federation of Gynecology and Obstetrics.

In countries where induced abortion is legally restricted, as in most of Latin America, evaluation of statistics related to induced abortions and abortion-related mortality is challenging. The present article reexamines recent reports estimating the number of induced abortions and abortion-related mortality in Mexico, with special reference to the International Classification of Diseases (ICD). We found significant overestimations of abortion figures in the Federal District of Mexico (up to 10-fold), where elective abortion has been legal since 2007. Significant overestimation of maternal and abortion-related mortality during the last 20 years in the entire Mexican country (up to 35%) was also found. Such overestimations are most likely due to the use of incomplete in-hospital records as well as subjective opinion surveys regarding induced abortion figures, and due to the consideration of causes of death that are unrelated to induced abortion, including flawed denominators of live births. Contrary to previous publications, we found important progress in maternal health, reflected by the decrease in overall maternal mortality (30.6%) from 1990 to 2010. The use of specific ICD codes revealed that the mortality ratio associated with induced abortion decreased 22.9% between 2002 and 2008 (from 1.48 to 1.14 deaths per 100,000 live births). Currently, approximately 98% of maternal deaths in Mexico are related to causes other than induced abortion, such as hemorrhage, hypertension and eclampsia, indirect causes, and other pathological conditions. Therefore, only marginal or null effects would be expected from changes in the legal status of abortion on overall maternal mortality rates. Rather, maternal health in Mexico would greatly benefit from increasing access to emergency and specialized obstetric care. Finally, more reliable methodologies to assess abortion-related deaths are clearly required. PMID:23271925

The purpose of this study was to examine associations between abortion history and a wide range of anxiety (panic disorder, panic attacks, PTSD, Agoraphobia), mood (bipolar disorder, mania, major depression), and substance abuse disorders (alcohol and drug abuse and dependence) using a nationally representative US sample, the national comorbidity survey. Abortion was found to be related to an increased risk for a variety of mental health problems (panic attacks, panic disorder, agoraphobia, PTSD, bipolar disorder, major depression with and without hierarchy), and substance abuse disorders after statistical controls were instituted for a wide range of personal, situational, and demographic variables. Calculation of population attributable risks indicated that abortion was implicated in between 4.3% and 16.6% of the incidence of these disorders. Future research is needed to identify mediating mechanisms linking abortion to various disorders and to understand individual difference factors associated with vulnerability to developing a particular mental health problem after abortion.
Resistance and vulnerability to stigmatization in abortion work.
O'Donnell, Jenny; Weitz, Tracy A; Freedman, Lori R
2011-11-01
The stigma surrounding abortion in the United States commonly permeates the experience of both those seeking this health service as well as those engaged in its provision. Annually there are approximately 1.2 million abortions performed in the United States; despite that existing research shows that abortion services are highly utilized, women rarely disclose their use of these services. In 2005 only 1787 facilities that offer abortion services remained, a drop of almost 40 percent since 1982 (Jones, Zolna, Henshaw, & Finer, 2008). While it has been acknowledged that all professionals working in abortion are labeled to some degree as different, no published research has explored stigmatization as a process experienced by the range of individuals that comprise the abortion-providing workforce in the USA. Using qualitative data from a group of healthcare professionals doing abortion work in a Western state, this study begins to fill that gap, providing evidence of how the experience of stigma can vary and is managed within interactions in the workplace, in professional circles, among family and friends, and among strangers. The analysis shows that the experience of stigma for those providing abortion care is not a static or fixed loss of status. It is a dynamic situation in which those vulnerable to stigmatization can avoid, resist, or transform the stigma that would attach to them by varying degrees within selective contexts.

Human parvovirus B19 is a very common viral infection especially in school-aged children. The infection during pregnancy can affect the fetus due to lack of mother's immunity. Although, there is still no evidence of fetal teratogenic effects with parvovirus B19, but non-immune fetal hydrops and abortion may be caused by vertical transmission of the virus during pregnancy. This study was aimed to assess the prevalence of parvovirus B19-specific antibody (IgM) in pregnant women who had a spontaneous abortion. This cross-sectional study was carried out in all pregnant women who referred due to a spontaneous abortion. All demographic information such as age, occupation, and gestational age, last history of abortion, gravity, and presence of children below the age of six was recorded and a blood sample was provided for all the women. Then, the blood samples were tested to assay parvovirus B19-specific antibody (IgM) by EuroImmune ELISA kit. Among 94 pregnant women with the mean age of 28.4 years who had a spontaneous abortion, parvovirus B19 specific antibody (IgM) was detected in 17 participants (18.1%). Meanwhile, 14 women (14.9%) were suspected for presence of the antibody in their blood sample. There was no significant difference between the presence of antibody and age of pregnant women, occupation, gestational age, number of previous abortion, presence of children below the age of six and number of pregnancy. These findings revealed that a high percentage of pregnant women are probably non-immune against parvovirus B19, and also there might be a number of spontaneous abortions in which parvovirus infection caused fetal death. However, more studies are needed to prove the absolute role of parvovirus B19 in these abortions.
Nursing and Hospital Abortions in the United States, 1967-1973.
Haugeberg, Karissa
2018-03-21
Before elective abortion was legalized nationally in 1973 with the U.S. Supreme Court decision Roe v. Wade, seventeen states and the District of Columbia liberalized their abortion statutes. While scholars have examined the history of physicians who had performed abortions before and after it was legal and of feminists' work to expand the range of healthcare choices available to women, we know relatively little about nurses' work with abortion. By focusing on the history of nursing in those states that liberalized their abortion laws before Roe, this article reveals how women who sought greater control over their lives by choosing abortion encountered medical professionals who were only just beginning to question the gendered conventions that framed labor roles in American hospitals. Nurses, whose workloads increased exponentially when abortion laws were liberalized, were rarely given sufficient training to care for abortion patients. Many nurses directed their frustrations to the women patients who sought the procedure. This essay considers how the expansion of women's right to abortion prompted nurses to question the gendered conventions that had shaped their work experiences.
Early abortion services in the United States: a provider survey.

The objective of this study was to describe the availability of early surgical and medical abortion among members of the National Abortion Federation (NAF) and to identify factors affecting the integration of early abortion services into current services. Telephone interviews were conducted with staff at 113 Planned Parenthood affiliates and independent abortion providers between February and April 2000, prior to FDA approval of mifepristone. Early abortion services were available at 59% of sites, and establishing services was less difficult than or about what was anticipated. Sites generally found it easier to begin offering early surgical abortion than early medical abortion. Physician participation was found to be critical to implementing early services. At sites where some but not all providers offered early abortion, variations in service availability resulted. Given the option of reconsidering early services, virtually all sites would make the same decision again. These data suggest that developing mentoring relationships between experienced early abortion providers/sites and those not offering early services, and training physicians and other staff, are likely to be effective approaches to expanding service availability.

The objective if this quantitative and cross study is to characterize female teenagers, from 12 to 19 years old, that committed abortion, in a representative random sample of 2592 adolescents in Maceió, in 2005. There were found 149 abortions, where most of them (81,9%) did not have a job, (85%) lived with the parents, (85,2%) were single, (69,8%) studied in a public school and (70,5%) were in high school. The majority had one abortion 93 % , but it stands out that 8,5 % of them aborted twice...

Unsafe abortions remain a major public health problem in countries with very restrictive abortion laws. In Brazil, parliamentarians - who have the power to change the law - are influenced by "public opinion", often obtained through surveys and opinion polls. This paper presents the findings from two studies. One was carried out in February-December 2010 among 1,660 public servants and the other in February-July 2011 with 874 medical students from three medical schools, both in São Paulo State, Brazil. Both groups of respondents were asked two sets of questions to obtain their opinion about abortion: 1) under which circumstances abortion should be permitted by law, and 2) whether or not women in general and women they knew who had had an abortion should be punished with prison, as Brazilian law mandates. The differences in their answers were enormous: the majority of respondents were against putting women who have had abortions in prison. Almost 60% of civil servants and 25% of medical students knew at least one woman who had had an illegal abortion; 85% of medical students and 83% of civil servants thought this person(s) should not be jailed. Brazilian parliamentarians who are currently reviewing a reform in the Penal Code need to have this information urgently. Copyright © 2013 Reproductive Health Matters. Published by Elsevier Ltd.

Shuttle Return-to-Flight IH-108 Aerothermal Test at CUBRC - Flow Field Calibration and CFD
Lau, Kei Y.; Holden, M. S.
2011-01-01
This paper discusses one specific aspect of the Shuttle Retrun-To-Flight IH-108 Aerothermal Test at Calspan-University of Buffalo Research Center (CUBRC), the test flow field calibration. It showed the versatility of the CUBRC Large Energy National Shock Tunnel (LENS) II wind tunnel for an aerothermal test with unique and demanding requirements. CFD analyses were used effectively to extend the test range at the low end of the Mach range. It demonstrated how ground test facility and CFD synergy can be utilitzed iteratively to enhance the confidence in the fedility of both tools. It addressed the lingering concerns of the aerothermal community on use of inpulse facility and CFD analysis. At the conclusion of the test program, members from the NASA Marshall (MSFC), CUBRC and USA (United Space Alliance) Consultants (The Grey Beards) were asked to independently verify the flight scaling data generated by Boeing for flight certification of the re-designed external tank (ET) components. The blind test comparison showed very good results.
Operational Lessons Learned from the Ares I-X Flight Test
Davis, Stephan R.
2010-01-01
The Ares I-X flight test, launched in 2009, is the first test of the Ares I crew launch vehicle. This development flight test evaluated the flight dynamics, roll control, and separation events, but also provided early insights into logistical, stacking, launch, and recovery operations for Ares I. Operational lessons will be especially important for NASA as the agency makes the transition from the Space Shuttle to the Constellation Program, which is designed to be less labor-intensive. The mission team itself comprised only 700 individuals over the life of the project compared to the thousands involved in Shuttle and Apollo missions; while missions to and beyond low-Earth orbit obviously will require additional personnel, this lean approach will serve as a model for future Constellation missions. To prepare for Ares I-X, vehicle stacking and launch infrastructure had to be modified at Kennedy Space Center's Vehicle Assembly Building (VAB) as well as Launch Complex (LC) 39B. In the VAB, several platforms and other structures designed for the Shuttle s configuration had to be removed to accommodate the in-line, much taller Ares I-X. Vehicle preparation activities resulted in delays, but also in lessons learned for ground operations personnel, including hardware deliveries, cable routing, transferred work and custodial paperwork. Ares I-X also proved to be a resource challenge, as individuals and ground service equipment (GSE) supporting the mission also were required for Shuttle or Atlas V operations at LC 40/41 at Cape Canaveral Air Force Station. At LC 39B, several Shuttle-specific access arms were removed and others were added to accommodate the in-line Ares vehicle. Ground command, control, and communication (GC3) hardware was incorporated into the Mobile Launcher Platform (MLP). The lightning protection system at LC 39B was replaced by a trio of 600-foot-tall towers connected by a catenary wire to account for the much greater height of the vehicle. Like Shuttle

The Gamma-ray Large Area Space telescope (GLAST) is a gamma-ray satellite scheduled for launch in 2008. Before the assembly of the Tracker subsystem of the Large Area Telescope (LAT) science instrument of GLAST, every component (tray) and module (tower) has been subjected to extensive ground testing required to ensure successful launch and on-orbit operation. This paper describes the sequence and results of the environmental tests performed on an engineering model and all the flight hardware of the GLAST LAT Tracker. Environmental tests include vibration testing, thermal cycles and thermal-vacuum cycles of every tray and tower as well as the verification of their electrical performance.
Abortion in context: historical trends and future changes.
Rossi, A S; Sitaraman, B
1988-01-01
Reform of abortion laws in the United States stemmed from concern over the health consequences of illegal abortion. Feminists were relative latecomers to the movement, and abortion did not become a major political issue until after the Roe v. Wade decision by the Supreme Court. Most social scientists began to study public attitudes toward abortion, which have been relatively stable since that 1973 decision, only after the Supreme Court ruling, and they thus probably missed documenting the period in which the major attitudinal changes occurred. Polls showed that the American public is most likely to approve of abortion when there is a fetal defect and when the pregnancy endangers maternal health or is the result of rape. These single reasons do not seem to jibe with the complexities of real life, however: The majority of women who have abortions indicate more than one reason for doing so, and the major reasons given concern the conflicting responsibilities of school, work and family and an inability to afford another child. A view of the abortion controversy that puts it into a larger context than do most polls and most American research suggests that legal abortion in the United States is unlikely to be jeopardized in the long run. The trend in most Western industrial nations is toward a more secularized society that features more individual discretion and less control by religious and political institutions over private aspects of life. In the immediate future, a number of factors will perpetuate the need for access to abortion. Among them are early sexual activity that often results in pregnancies among very young women; dim prospects for innovative technological advances in the contraceptive field; and the AIDS epidemic, which may result in the use of contraceptives that are more effective against that deadly virus but less effective at preventing pregnancy. Nor will abortion decisions become any easier for the families and individuals involved, as technology

Adaptive flight control systems have the potential to be more resilient to extreme changes in airplane behavior. Extreme changes could be a result of a system failure or of damage to the airplane. A direct adaptive neural-network-based flight control system was developed for the National Aeronautics and Space Administration NF-15B Intelligent Flight Control System airplane and subjected to an inflight simulation of a failed (frozen) (unmovable) stabilator. Formation flight handling qualities evaluations were performed with and without neural network adaptation. The results of these flight tests are presented. Comparison with simulation predictions and analysis of the performance of the adaptation system are discussed. The performance of the adaptation system is assessed in terms of its ability to decouple the roll and pitch response and reestablish good onboard model tracking. Flight evaluation with the simulated stabilator failure and adaptation engaged showed that there was generally improvement in the pitch response; however, a tendency for roll pilot-induced oscillation was experienced. A detailed discussion of the cause of the mixed results is presented.

The functional task test is a multi-disciplinary study investigating how space-flight induced changes to physiological systems impacts functional task performance. Impairment of neuromuscular function would be expected to negatively affect functional performance of crewmembers following exposure to microgravity. This presentation reports the results for muscle performance testing in crewmembers. Functional task performance will be presented in the abstract "Functional Task Test 1: sensory motor adaptations associated with postflight alternations in astronaut functional task performance." METHODS: Muscle performance measures were obtained in crewmembers before and after short-duration space flight aboard the Space Shuttle and long-duration International Space Station (ISS) missions. The battery of muscle performance tests included leg press and bench press measures of isometric force, isotonic power and total work. Knee extension was used for the measurement of central activation and maximal isometric force. Upper and lower body force steadiness control were measured on the bench press and knee extension machine, respectively. Tests were implemented 60 and 30 days before launch, on landing day (Shuttle crew only), and 6, 10 and 30 days after landing. Seven Space Shuttle crew and four ISS crew have completed the muscle performance testing to date. RESULTS: Preliminary results for Space Shuttle crew reveal significant reductions in the leg press performance metrics of maximal isometric force, power and total work on R+0 (pperformance metrics were observed in returning Shuttle crew and these adaptations are likely contributors to impaired functional tasks that are ambulatory in nature (See abstract Functional Task Test: 1). Interestingly, no significant changes in central activation capacity were detected. Therefore, impairments in muscle function in response to short-duration space flight are likely myocellular rather than neuromotor in nature.
