    Modern power system is dealt with overloading problem especially transmission network which works on their maximum limit. Today’s power system network tends to become unstable and prone to collapse due to disturbances. Flexible AC Transmission system (FACTS) provides solution to problems like line overloading, voltage stability, losses, power flow etc. FACTS can play important role in improving static and dynamic performance of power system. FACTS devices need high initial investment. Therefore, FACTS location, type and their rating are vital and should be optimized to place in the network for maximum benefit. In this paper, different optimization methods like Particle Swarm Optimization (PSO), Genetic Algorithm (GA) etc. are discussed and compared for optimal location, type and rating of devices. FACTS devices such as Thyristor Controlled Series Compensator (TCSC), Static Var Compensator (SVC) and Static Synchronous Compensator (STATCOM) are considered here. Mentioned FACTS controllers effects on different IEEE bus network parameters like generation cost, active power loss, voltage stability etc. have been analyzed and compared among the devices.

    This paper presents multi-objective differential evolution to optimize cost of generation, emission and active power transmission loss of flexible ac transmission systems (FACTS) device-equipped power systems. In the proposed approach, optimal power flow problem is formulated as a multi-objective optimization problem. FACTS devices considered include thyristor controlled series capacitor (TCSC) and thyristor controlled phase shifter (TCPS). The proposed approach has been examined and tested on the modified IEEE 30-bus and 57-bus test systems. The results obtained from the proposed approach have been compared with those obtained from nondominated sorting genetic algorithm-II, strength pareto evolutionary algorithm 2 and pareto differential evolution.

    Full Text Available In this paper, Gravitational Search Algorithm (GSA is used as optimization method in reactive power planning using FACTS (Flexible AC transmission system devices. The planning problem is formulated as a single objective optimization problem where the real power loss and bus voltage deviations are minimized under different loading conditions. GSA based optimization algorithm and particle swarm optimization techniques (PSO are applied on IEEE 30 bus system. Results show that GSA can also be a very effective tool for reactive power planning.

    In this work techniques for the location of FACTS devices (Flexible Systems of AC Transmission) in a multi-machine power system in order to improve the electromechanical transient behavior is presented. In the first part, a brief introduction is presented about the FACTS devices, in which are mentioned some of the main characteristics, classification and advantages that their utilization represents. In the next part, the formulation of the matrix of state in the context of machine-infinite bar considering the possibility of including a power system stabilizer is developed. Later the formulation is extended to a multi-machine system. Additionally the form of including a series capacitor controlled by thyristors (TCSC) as well as a unified controller of power flows (UPFC) is analyzed. An analysis of the UPFC is carried out in conditions of stationary and dynamic state in a system machine-infinite bar in order to know its operating characteristics and its capacity for dampening power oscillations through its entrances of control when using local signals. In the last part of the work a methodology is proposed to attack the problem of the location of FACTS devices, which is based in the technique of response to the system frequency. In order to validate this proposal some cases of study are used and the results obtained with the ones provided by other techniques are compared. Also some auxiliary means are proposed for obtaining the feasible locations utilizing other mathematical tools such as the singular values and the sensitivities. Finally, simulations in the time are carried out to corroborate the results obtained.

    This paper presents a new and accurate fault location algorithm based on distributed time domain line model for a transmission line compensated with series connected FACTS device. In the proposed algorithm, in order to compute the voltage drop across the series device during the fault period, the series device model and knowledge about the operating mode of the compensating device are not utilized. For this reason, the proposed technique can be easily applied to any series FACTS compensated line. Samples of voltage and current at both ends of the line are taken synchronously and used to calculate the location and resistance of the fault. The proposed algorithm is not sensitive to fault resistance and fault inception angle and does not require any knowledge of equivalent source impedances. This method has been tested using EMTP/ATP model of a 400 kV, 300 km transmission line compensated with a series FACTS device. The results of computer simulations for different operating conditions demonstrate the very high accuracy and robustness of the algorithm. (author)

    Full Text Available Integration of wind turbines may have significant impacts on power system operation and generation of electricity from wind power has received considerable attention. This paper analyses the impact of integrating wind generation based on double feed induction generators (DFIG and Flexible AC Transmission System (FACTS on the voltage collapse and active losses of network IEEE 30 bus test. Therefore, we must choose among FACTS devices, those with specific applications such as maintaining the voltage at the desired value and the control of power flow, SVC is the most effective in the compensation of reactive as well as maintaining the voltage, and TCSC is the best choice for a proper control of power flow and consequently the reduction of active losses. The simulation results show clearly the effect of wind power plants and FACTS on the grid, voltage stability and power quality of electric power system.

    2016-03-01

    Full Text Available In this paper, symbiotic organisms search (SOS algorithm is proposed for the solution of optimal power flow (OPF problem of power system equipped with flexible ac transmission systems (FACTS devices. Inspired by interaction between organisms in ecosystem, SOS algorithm is a recent population based algorithm which does not require any algorithm specific control parameters unlike other algorithms. The performance of the proposed SOS algorithm is tested on the modified IEEE-30 bus and IEEE-57 bus test systems incorporating two types of FACTS devices, namely, thyristor controlled series capacitor and thyristor controlled phase shifter at fixed locations. The OPF problem of the present work is formulated with four different objective functions viz. (a fuel cost minimization, (b transmission active power loss minimization, (c emission reduction and (d minimization of combined economic and environmental cost. The simulation results exhibit the potential of the proposed SOS algorithm and demonstrate its effectiveness for solving the OPF problem of power system incorporating FACTS devices over the other evolutionary optimization techniques that surfaced in the recent state-of-the-art literature.

  12. Optimal location of FACTS devices for congestion management and loadability enhancement

    2017-09-01

    Full Text Available Due to the growth of electricity demands and transactions in power markets, existing power networks need to be enhanced in order to increase their loadability. Two types of FACTS devices, SVC and TCSC, can be installed on buses and transmission lines to relieve congestion and enhance the loadability of power systems, respectively through injecting reactive power and changing line reactance. Proper location of SVC and TCSC is a key to maximize loadability. In this paper, the eigenvalue structure analysis combined with min-cut algorithm has been proposed to determine optimal location of SVC and TCSC. Transmission system loadability enhancement using FACTS requires a two-step approach. First, the optimal location of the FACTS in the network must be ascertained and then, the continuation power flow programming (CPF with fixed FACTS parameters is solved. Study results on IEEE 14-, IEEE 30- and IEEE 118 bus system show that the proposed method is capable of finding the best location for FACTS installation to relieve congestion and enhance the loadability.

    2010-06-01

    Property Assessed Clean Energy (PACE) financing is one of several new financial models broadening access to clean energy by addressing the barrier of initial capital cost. The majority of the PACE programs in the market today include PV as an eligible measure. PV appeals to homeowners as a way to reduce utility bills, self-generate sustainable power, increase energy independence and demonstrate a commitment to the environment. If substantial state incentives for PV exist, PV projects can be economic under PACE, especially when partnered with good net metering policies. At the same time, PV is expensive relative to other eligible measures with a return on investment horizon that might exceed program targets. This fact sheet reviews the benefits and potential challenges of including PV in PACE programs.

    Flexible Alternating Current Transmission Systems (FACTS) devices are installed on electric power transmission lines to stabilize and regulate power flow. Power lines protected by FACTS devices can increase power flow and better respond to contingencies. The University of Missouri Rolla (UMR) is currently working on a multi-year project to examine the potential use of multiple FACTS devices distributed over a large power system region in a cooperative arrangement in which the FACTS devices work together to optimize and stabilize the regional power system. The report describes operational and security challenges that need to be addressed to employ FACTS devices in this way and recommends references, processes, technologies, and policies to address these challenges.

  15. Locating of Series FACTS Devices for Multi-Objective Congestion Management Using Components of Nodal Prices

    Directory of Open Access Journals (Sweden)

    A. R. Moradi

    2017-03-01

    Full Text Available Congestion and overloading for lines are the main problems in the exploitation of power grids. The consequences of these problems in deregulated systems can be mentioned as sudden jumps in prices in some parts of the power system, lead to an increase in market power and reduction of competition in it. FACTS devices are efficient, powerful and economical tools in controlling power flows through transmission lines that play a fundamental role in congestion management. However, after removing congestion, power systems due to targeting security restrictions may be managed with a lower voltage or transient stability rather than before removing. Thus, power system stability should be considered within the construction of congestion management. In this paper, a multi-objective structure is presented for congestion management that simultaneously optimizes goals such as total operating cost, voltage and transient security. In order to achieve the desired goals, locating and sizing of series FACTS devices are done with using components of nodal prices and the newly developed grey wolf optimizer (GWO algorithm, respectively. In order to evaluate reliability of mentioned approaches, a simulation is done on the 39-bus New England network.

    To damp power system multi-mode oscillations, the commonly-used method is to arrange multiple decentralized stabilizers, such as PSS (Power System Stabilizer) and FACTS (Flexible AC Transmission Systems) stabilizers. In order to overcome the problem of interactions between stabilizers, coordinated design of multiple decentralized stabilizers has been proposed to simultaneously set parameters of all stabilizers. However, in practice it could be very difficult to implement the coordinated design of multiple stabilizers. This is because those stabilizers are often at different geographical locations in a power system and cross-location simultaneous field tuning of stabilizers' parameters is a tremendous task due to their interactions. Hence this paper proposes a novel scheme of damping power system multi-mode oscillations by using a single FACTS device and presents the results of feasibility study of the proposed scheme. It is demonstrated that multiple stabilizers can be arranged in a single FACTS device to effectively damp power system multi-mode oscillations. Under this scheme, multiple stabilizers are at a same geographical location in the power system and hence their parameters can be tuned simultaneously in coordination in the field. In the paper, three examples of multi-machine power systems installed with a UPFC (Unified Power Flow Controller), a STATCOM (Static Synchronous Compensator)/BESS (Battery Energy Storage System) and a MUPFC (Multiple-terminal UPFC) respectively are presented. Parameters of multiple stabilizers are designed in coordination by using a newly appeared method of optimisation-artificial fish swarm algorithm. Simulation results in the paper are compared with those obtained from applying the conventional scheme of decentralized control involving multiple PSSs. They demonstrate and confirm the feasibility of proposed scheme in the paper. (author)

    Various flexible AC transmission system (FACTS) devices were investigated in this study. A static VAR compensator (SVC), static synchronous compensator (STATCOM) and a unified power flow controller (UPFC) were simulated in order to determine their voltage regulation and power flow control ability for a 330 kV transmission system in Nigeria. The FACTS models were tested on standard power networks and then modelled with a Newton-Raphson algorithm as part of a power flow analysis. The study identified potential locations for the devices in the Nigerian transmission network. Four case studies were considered in order to determine optimal configurations for the devices within the network. The study showed that the SVC and STATCOM devices regulate voltage buses without violating susceptance or voltage limits. The UPFC can control active power flow through transmission lines connecting the northern region of the country to areas with a high demand for power supply. 10 refs., 7 tabs., 5 figs.

As of 2014, 90 % of US adults have a mobile phone, with 58 % having a smartphone, 32 % owning some type of e-reader, and 42 % of US adults owning a tablet computer. Mobile devices are particularly well-suited for the study of common conditions such as sleep difficulties because of their ubiquity. Around 35 to 49 % of the US adult population have problems falling asleep or have daytime sleepiness. These sleep disorders are often under-recognized because of patient-physician communication difficulties, low rates of medical awareness resulting in underreporting of insomnia symptoms, and limited primary care physician (PCP) training in insomnia recognition. Mobile devices have the potential to bridge some of these gaps, but they can also lead to sleep difficulties when used inappropriately.

  5. Integrated control of wind farms, FACTS devices and the power network using neural networks and adaptive critic designs

    Science.gov (United States)

    Qiao, Wei

    Worldwide concern about the environmental problems and a possible energy crisis has led to increasing interest in clean and renewable energy generation. Among various renewable energy sources, wind power is the most rapidly growing one. Therefore, how to provide efficient, reliable, and high-performance wind power generation and distribution has become an important and practical issue in the power industry. In addition, because of the new constraints placed by the environmental and economical factors, the trend of power system planning and operation is toward maximum utilization of the existing infrastructure with tight system operating and stability margins. This trend, together with the increased penetration of renewable energy sources, will bring new challenges to power system operation, control, stability and reliability which require innovative solutions. Flexible ac transmission system (FACTS) devices, through their fast, flexible, and effective control capability, provide one possible solution to these challenges. To fully utilize the capability of individual power system components, e.g., wind turbine generators (WTGs) and FACTS devices, their control systems must be suitably designed with high reliability. Moreover, in order to optimize local as well as system-wide performance and stability of the power system, real-time local and wide-area coordinated control is becoming an important issue. Power systems containing conventional synchronous generators, WTGs, and FACTS devices are large-scale, nonlinear, nonstationary, stochastic and complex systems distributed over large geographic areas. Traditional mathematical tools and system control techniques have limitations to control such complex systems to achieve an optimal performance. Intelligent and bio-inspired techniques, such as swarm intelligence, neural networks, and adaptive critic designs, are emerging as promising alternative technologies for power system control and performance optimization.

    Audiological and subjective benefits in adult bone-anchored hearing device users. Retrospective evaluation. Tertiary referral center. Thirty-eight adult subjects fitted with unilateral bone-anchored hearing device. Audiometric measurements included sound-field pure-tone and speech audiometries (speech reception threshold, maximum speech discrimination). Subjective benefit was assessed by the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire. Ipsilateral and contralateral hearing loss was considered. Comparison was drawn between Compact, Divino, and Intenso processors. To compare sound-field pure-tone and speech audiometries and APHAB results with and without the device adjusted for the unaided results. With the device, sound-field pure-tone audiometry results revealed an increase gain in all frequencies. Sound-field speech audiometry showed that the mean threshold of speech recognition was 20 dB lower, maximum discrimination was attained at 5 dB less, and percentage of maximum discrimination increased by 5%. Scores in the APHAB questionnaire decreased except for the aversiveness subscale. Auditory-adjusted gain showed greater benefit in subjects with ipsilateral conductive hearing loss.Subjects with contralateral normal hearing or conductive hearing loss showed greater improvement that those with contralateral mixed or sensorineural hearing loss. There were no differences between Compact, Divino and Intenso processors. When comparisons are adjusted for unaided condition, the bone-anchored hearing device provided auditory and subjective benefit in subjects with ipsilateral conductive hearing loss and contralateral normal hearing or conductive hearing loss. It gave marginal benefit in ipsilateral mixed and contralateral mixed or sensorineural hearing loss. No differences were found between the Compact, Intenso, and Divino processors.

    The terrorist attacks of September 11, 2001 have resulted in dramatic changes in aviation security. As of early 2003, an estimated 1,100 explosive detection systems (EDS) and 6,000 explosive trace detection machines (ETD) have been deployed to ensure 100% checked baggage screening at all commercial airports throughout the United States. The prohibitive costs associated with deploying and operating such devices is a serious issue for the Transportation Security Administration. This article evaluates the cost effectiveness of the explosive detection technologies currently deployed to screen checked baggage as well as new technologies that could be used in the future. Both single-device and two-device systems are considered. In particular, the expected annual direct cost of using these devices for 100% checked baggage screening under various scenarios is obtained and the tradeoffs between using single- and two-device strategies are studied. The expected number of successful threats under the different checked baggage screening scenarios with 100% checked baggage screening is also obtained. Lastly, a risk-based screening strategy proposed in the literature is analyzed. The results reported suggest that for the existing security setup, with current device costs and probability parameters, single-device systems are less costly and have fewer expected number of successful threats than two-device systems due to the way the second device affects the alarm or clear decision. The risk-based approach is found to have the potential to significantly improve security. The cost model introduced provides an effective tool for the execution of cost-benefit analyses of alternative device configurations for aviation-checked baggage security screening.

    In 2004, the United States Food and Drug Administration approved a radiofrequency identification (RFID) device that is implanted under the skin of the upper arm of patients and that stores the patient's medical identifier. When a scanner is passed over the device, the identifier is displayed on the screen of an RFID reader. An authorized health professional can then use the identifier to access the patient's clinical information, which is stored in a separate, secure database.

    Full Text Available In 2004, the United States Food and Drug Administration approved a radiofrequency identification (RFID device that is implanted under the skin of the upper arm of patients and that stores the patient's medical identifier. When a scanner is passed over the device, the identifier is displayed on the screen of an RFID reader. An authorized health professional can then use the identifier to access the patient's clinical information, which is stored in a separate, secure database. Such RFID devices may have many medical benefits--such as expediting identification of patients and retrieval of their medical records. But critics of the technology have raised several concerns, including the risk of the patient's identifying information being used for nonmedical purposes.

  6. Fact versus fiction. The socio-economic benefits to be found in teaching critical thinking skills on nuclear waste issues in public schools

    International Nuclear Information System (INIS)

    Anderson, H.

    1984-01-01

    The safe storage of radioactive wastes has been the topic of much heated debate. Many of the concerns raised demonstrate that the public is poorly informed about nuclear matters, bewildered by conflicting testimony and lacking the intellectual skills required to discriminate between statements of fact versus opinion or motive. Recently, the National Council for the Social Studies (NCSS) adopted a set of guidelines intended to encourage a stronger emphasis on urgent science-related social issues in the classroom and to provide for social studies teachers, rational and structure for the presentation of these issues. In this way, the NCSS is moving to meet the needs of the community for greater technological awareness. NCSS believes students need instruction and strategies for evaluating science-related material intelligently. As a case study in point, the topic ''Nuclear Waste: A Science Related Social Issue of Urgent Concern'' was brought before a recent NCSS national meeting. This paper discusses strategies for dealing with nuclear waste issues in the classroom and the potential socio-economic benefits to be found in dispelling myths surrounding nuclear issues

  12. Medical-device risk management and public safety: using cost-benefit as a measurement of effectiveness

    Science.gov (United States)

    Hughes, Allen A.

    1994-12-01

    Public safety can be enhanced through the development of a comprehensive medical device risk management. This can be accomplished through case studies using a framework that incorporates cost-benefit analysis in the evaluation of risk management attributes. This paper presents a framework for evaluating the risk management system for regulatory Class III medical devices. The framework consists of the following sixteen attributes of a comprehensive medical device risk management system: fault/failure analysis, premarket testing/clinical trials, post-approval studies, manufacturer sponsored hospital studies, product labeling, establishment inspections, problem reporting program, mandatory hospital reporting, medical literature surveillance, device/patient registries, device performance monitoring, returned product analysis, autopsy program, emergency treatment funds/interim compensation, product liability, and alternative compensation mechanisms. Review of performance histories for several medical devices can reveal the value of information for many attributes, and also the inter-dependencies of the attributes in generating risk information flow. Such an information flow network is presented as a starting point for enhancing medical device risk management by focusing on attributes with high net benefit values and potential to spur information dissemination.

  13. Use and perceived benefits of mobile devices by physicians in preventing adverse drug events in the nursing home.

    Handler, Steven M; Boyce, Richard D; Ligons, Frank M; Perera, Subashan; Nace, David A; Hochheiser, Harry

    2013-12-01

    Although mobile devices equipped with drug reference software may help prevent adverse drug events (ADEs) in the nursing home (NH) by providing medication information at the point of care, little is known about their use and perceived benefits. The goal of this study was to conduct a survey of a nationally representative sample of NH physicians to quantify the use and perceived benefits of mobile devices in preventing ADEs in the NH setting. We surveyed physicians who attended the 2010 American Medical Directors Association Annual Symposium about their use of mobile devices, and beliefs about the effectiveness of drug reference software in preventing ADEs. The overall net valid response rate was 70% (558/800) with 42% (236/558) using mobile devices to assist with prescribing in the NH. Physicians with 15 or fewer years of clinical experience were 67% more likely to be mobile device users, compared with those with more than 15 years of clinical experience (odds ratio = 1.68; 95% confidence interval = 1.17-2.41; P = .005). For those who used a mobile device to assist with prescribing, almost all (98%) reported performing an average of 1 or more drug look-ups per day, performed an average of 1 to 2 lookups per day for potential drug-drug interactions (DDIs), and most (88%) believed that drug reference software had helped to prevent at least 1 potential ADE in the preceding 4-week period. The proportion of NH physicians who use mobile devices with drug reference software, although significant, is lower than in other clinical environments. Our results suggest that NH physicians who use mobile devices equipped with drug reference software believe they are helpful for reducing ADEs. Further research is needed to better characterize the facilitators and barriers to adoption of the technology in the NH and its precise impact on NH ADEs.

    Hougaard, Dan Dupont; Boldsen, Soren Kjaergaard; Jensen, Anne Marie; Hansen, Soren; Thomassen, Per Cayé

    2017-08-01

    Examination of objective as well as subjective outcomes with a new transcutaneous bone-anchored hearing aid device. The study was designed as a prospective multicenter consecutive case-series study involving tertiary referral centers at two Danish University Hospitals. A total of 23 patients were implanted. Three were lost to follow-up. Patients had single-sided deafness, conductive or mixed hearing loss. Rehabilitative. Aided and unaided sound field hearing was evaluated objectively using (1) pure warble tone thresholds, (2) pure-tone average (PTA4), (3) speech discrimination score (SDS) in quiet, and (4) speech reception threshold 50% at 70 dB SPL noise level (SRT50%). Subjective benefit was evaluated by three validated questionnaires: (1) the IOI-HA, (2) the SSQ-12, and (3) a questionnaire evaluating both the frequency and the duration of hearing aid usage. The mean aided PTA4 was lowered by 14.7 dB. SDS was increased by 37.5% at 50 dB SPL, SRT50% in noise improved 1.4 dB. Aided thresholds improved insignificantly at frequencies above 2 kHz. 52.9% of the patients used their device every day, and 76.5% used the device at least 5 days a week. Mean IOI-HA score was 3.4, corresponding to a good benefit. In SSQ-12, "quality of hearing" scored especially high. Patients with a conductive and/or mixed hearing loss benefitted the most. This device demonstrates a significant subjective hearing benefit 8 month post surgery. In patients with conductive and/or mixed hearing losses, patient satisfaction and frequency of use were high. Objective gain measures showed less promising results especially in patients with single-sided deafness (SSD) compared to other bone conduction devices.

  18. Overview of a benefit/risk ratio optimized for a radiation emitting device used in non-destructive testing

    Energy Technology Data Exchange (ETDEWEB)

    Maharaj, H.P., E-mail: H_P_Maharaj@hc-sc.gc.ca [Health Canada, Dept. of Health, Consumer and Clinical Radiaton Protection Bureau, Ottawa, Ontario (Canada)

    2016-03-15

    This paper aims to provide an overview of an optimized benefit/risk ratio for a radiation emitting device. The device, which is portable, hand-held, and open-beam x-ray tube based, is utilized by a wide variety of industries for purposes of determining elemental or chemical analyses of materials in-situ based on fluorescent x-rays. These analyses do not cause damage or permanent alteration of the test materials and are considered a non-destructive test (NDT). Briefly, the key characteristics, principles of use and radiation hazards associated with the Hay device are presented and discussed. In view of the potential radiation risks, a long term strategy that incorporates risk factors and guiding principles intended to mitigate the radiation risks to the end user was considered and applied. Consequently, an operator certification program was developed on the basis of an International Standards Organization (ISO) standard (ISO 20807:2004) and in collaboration with various stake holders and was implemented by a federal national NDT certification body several years ago. It comprises a written radiation safety examination and hands-on training with the x-ray device. The operator certification program was recently revised and the changes appear beneficial. There is a fivefold increase in operator certification (Levels 1 a nd 2) to date compared with earlier years. Results are favorable and promising. An operational guidance document is available to help mitigate radiation risks. Operator certification in conjunction with the use of the operational guidance document is prudent, and is recommended for end users of the x-ray device. Manufacturers and owners of the x-ray devices will also benefit from the operational guidance document. (author)

    This paper describes how the Atlas of Human Cardiac Anatomy website can be used to improve cardiac device design throughout the process of development. The Atlas is a free-access website featuring novel images of both functional and fixed human cardiac anatomy from over 250 human heart specimens. This website provides numerous educational tutorials on anatomy, physiology and various imaging modalities. For instance, the 'device tutorial' provides examples of devices that were either present at the time of in vitro reanimation or were subsequently delivered, including leads, catheters, valves, annuloplasty rings and stents. Another section of the website displays 3D models of the vasculature, blood volumes and/or tissue volumes reconstructed from computed tomography and magnetic resonance images of various heart specimens. The website shares library images, video clips and computed tomography and MRI DICOM files in honor of the generous gifts received from donors and their families.

  1. Implantable Medical Device Website Efficacy in Informing Consumers Weighing Benefits/Risks of Health Care Options.

    2016-01-01

    As more individuals turn to the Internet for health-related information and technology increases the availability and use of implantable medical devices (IMDs), the websites marketing these devices will increase. Healthy People 2020 mandates increased understandability and usability of health-related websites. This project used social cognitive theory (SCT) and health literacy constructs from the Institute of Medicine and National Institutes of Health to analyze eight IMD websites. Despite current recommendations, none of the websites considered for this study offered content of an appropriate reading level in conjunction with the United States average of eighth grade, and 75% of the sites failed to satisfy more than one health literacy construct. Most of the websites lacked many of the SCT constructs. More attention is needed to improve the usability of these and future IMD websites to simultaneously meet the goal of marketing IMDs and the Healthy People 2020 goals to educate patients and promote public health.

  2. Physical assistance devices in complex motor skill learning: benefits of a self-controlled practice schedule.

    Wulf, G; Toole, T

    1999-09-01

    This study examines the effects of a self-controlled use of physical assistance devices on learning a complex motor skill (i.e., producing slalom-type movements on a ski simulator). Physical assistance was provided by ski poles. One group of learners (self-control) was provided with the poles whenever they requested them, whereas another (yoked) group had no influence on the pole/no-pole schedule. While there were no group differences during the practice phase (Days 1 and 2), clear group differences emerged in the retention test without poles (Day 3). The self-control group produced significantly larger amplitudes than the yoked group. These results extend previous findings by showing learning advantages of the self-controlled use of physical assistance devices in complex motor skill learning.

    BACKGROUND: Positive expiratory pressure (PEP) is regularly used as a self-administered airway clearance technique. OBJECTIVE: The aim of this study was to evaluate the need to teach the correct use of the PEP device and to measure the progress of the success rate of the maneuver after training. METHOD: A PEP system (PariPEP-S Sytem) was used to generate PEP in 30 healthy volunteers. They were instructed by a qualified physical therapist to breathe correctly through the PEP device. Then they were evaluated during a set of ten expirations. Two other evaluations were performed at day 2 and day 8 (before and after feedback). The mean PEP and the success rate were calculated for each set of expirations. The number of maneuvers needed to obtain a correct use was calculated on the first session. RESULTS: An optimal PEP was reached after 7.5 SD 2.7 attempts by all subjects. Success rates and mean pressures were similar between the different sets of expirations (p=0.720 and p=0.326, respectively). Pressure variability was around 10%. After one week, 30% of subjects generated more than two non-optimal pressures in the set of ten expirations. No difference in success rate was observed depending on the evaluations. CONCLUSION: This study demonstrates that good initial training on the use of the PEP device and regular follow-up are required for the subject to reach optimal expiratory pressure. PMID:26647746

    Out-of-hospital cardiac arrest (OHCA) is a major cause of death and morbidity in the United States. Quality cardiopulmonary resuscitation (CPR) has proven to be a key factor in improving survival. The aim of our study was to investigate the outcomes of OHCA when mechanical CPR (LUCAS 2 Chest Compression System™) was utilized compared to conventional CPR. Although controlled trials have not demonstrated a survival benefit to the routine use of mechanical CPR devices, there continues to be an interest for their use in OHCA. We conducted a retrospective observational study of OHCA comparing the outcomes of mechanical and manual chest compressions in a fire department based EMS system serving a population of 1.4 million residents. Mechanical CPR devices were geographically distributed on 11 of 33 paramedic ambulances. Data were collected over a 36-month period and outcomes were dichotomized based on utilization of mechanical CPR. The primary outcome measure was survival to hospital discharge with a cerebral performance category (CPC) score of 1 or 2. This series had 3,469 OHCA reports, of which 2,999 had outcome data and met the inclusion criteria. Of these 2,236 received only manual CPR and 763 utilized a mechanical CPR device during the resuscitation. Return of spontaneous circulation (ROSC) was attained in 44% (334/763) of the mechanical CPR resuscitations and in 46% (1,020/2,236) of the standard manual CPR resuscitations (p = 0.32). Survival to hospital discharge was observed in 7% (52/763) of the mechanical CPR resuscitations and 9% (191/2,236) of the manual CPR group (p = 0.13). Discharge with a CPC score of 1 or 2 was observed in 4% (29/763) of the mechanical CPR resuscitation group and 6% (129/2,236) of the manual CPR group (p = 0.036). In our study, use of the mechanical CPR device was associated with a poor neurologic outcome at hospital discharge. However, this difference was no longer evident after logistic regression adjusting for confounding variables

    It is analyzed the ability of the Unified Power Flow Controller - FACTS UPFC, when equipped to Power Oscillation Damping - (POD) - a additional controller - to cushion low frequency oscillations in the electric power system (EPS). For this purpose, the MPS - Model of the Power Sensibility, which has as the main concept the application of the power nodal balance in each bar of the system, is used to represent the EPS. The analysis of sensibility, through the method of residues - that gives information about the control and observation of an input and output set to the controller - will provide the best place to install the UPFC/POD set and the procedures to adjust the parameters of the controller.

    To longitudinally evaluate short- and long-term subject satisfaction/benefit perception, device usage rates, complication rates, and external device repair rates of bone-anchored hearing aid (BAHA) implantation on a cohort of adult subjects with profound unilateral sensorineural hearing loss (PUSHL). Prospective clinical trial. Tertiary referral center. Fifty-six adults with PUSHL, 21 of which underwent BAHA implantation (followed for an average of 3.2 years after implantation; range, 0.8-4.6 yr). Short- and long-term satisfaction/benefit perception outcomes consisting of the Glasgow Hearing Aid Benefit Profile, Abbreviated Profile of Hearing Aid Benefit, and Single-Sided Deafness Questionnaire, including a comparison of results between implanted and nonimplanted subjects. Short- and long-term device usage rates, complications, and device failure issues also were carefully documented. There were statistically significant improvements in nearly all measures of benefit perception documented as well as a high rate of long-term device usage (81%). Although satisfaction and benefit perception outcomes generally tended to regress over time when compared with initial short-term outcomes, long-term scores still tended to be significantly improved nevertheless as compared with preoperative levels. Approximately 38% of implants experienced severe local skin reactions (Grade 2 and above) around the implant site at some point throughout the follow-up period, whereas only one (4.8%) required implant removal. 66.7% of subjects required repair of their external sound processor. BAHA implantation seems to provide a high level of short- and long-term perceived benefit and satisfaction in subjects with PUSHL and high rate of long-term device usage. Implant site adverse local skin reactions and repairs of the external sound processor were quite common.

  11. Understanding benefits and addressing misperceptions and barriers to intrauterine device access among populations in the United States

    Science.gov (United States)

    Yoost, Jennie

    2014-01-01

    Three intrauterine devices (IUDs), one copper and two containing the progestin levonorgestrel, are available for use in the United States. IUDs offer higher rates of contraceptive efficacy than nonlong-acting methods, and several studies have demonstrated higher satisfaction rates and continuation rates of any birth control method. This efficacy is not affected by age or parity. The safety of IUDs is well studied, and the risks of pelvic inflammatory disease, perforation, expulsion, and ectopic pregnancy are all of very low incidence. Noncontraceptive benefits include decreased menstrual blood loss, improved dysmenorrhea, improved pelvic pain associated with endometriosis, and protection of the endometrium from hyperplasia. The use of IUDs is accepted in patients with multiple medical problems who may have contraindications to other birth control methods. Yet despite well-published data, concerns and misperceptions still persist, especially among younger populations and nulliparous women. Medical governing bodies advocate for use of IUDs in these populations, as safety and efficacy is unchanged, and IUDs have been shown to decrease unintended pregnancies. Dispersion of accurate information among patients and practitioners is needed to further increase the acceptability and use of IUDs. PMID:25050062

    Under the shadow of the tobacco epidemic, the sale and use of e-cigarettes and other vapour devices is increasing dramatically. A contentious debate has risen within public health over the harms and benefits of these devices. Clearing the Air seeks to clarify the issues with a systematic review that informs the pressing regulatory and public health decisions to be made regarding these new products. Using an integrated knowledge translation approach, public health researchers and knowledge users will work collaboratively throughout the project. Our research questions are the following: (1) What are the health risks and benefits of vapour devices, and how do these compare to cigarettes? (2) What is the harm reduction potential of vapour devices for individuals, the environment, and society? (3) Does youth vapour device experimentation lead to cigarette use? (4) Can vapour devices be effective aids for tobacco cessation? and (5) What is the potential toxicity of second-hand vapour? We are using meta-narrative review to synthesize studies from diverse research traditions because of its capacity to address contestations around a topic. The project has six phases. In the planning phase, we finalized the research questions. In the search phase, we are locating academic publications and grey literature aided by a research librarian. The mapping phase involves categorizing these papers into research traditions to understand different perspectives on the evidence for each research question. In the appraisal phase, we will select and evaluate the relevant papers. Finally, in the synthesis phase, using analytic techniques unique to meta-narrative methodology, we will compare and contrast the evidence from different research traditions to answer our research questions, identifying overarching meta-narratives. In the final stage, the full team will draft recommendations to be disseminated through a variety of knowledge translation strategies. Meta-narrative synthesis has the

  17. Complications and 1-year benefit of cardiac resynchronization therapy in patients over 75 years of age - Insights from the German Device Registry.

    Evidence on cardiac resynchronization therapy (CRT) in older patients is scarce and conflicting. Nevertheless, CRT in the elderly is of major practical relevance as heart failure prevalence increases with age. The German Device Registry (DEVICE) is a nationwide, prospective registry with a longitudinal follow-up design investigating device implantations in 60 German centres. The present analysis of DEVICE focussed on perioperative complication rates and 1-year outcome of patients ≥75years (n=320) compared to younger patients (n=879) receiving a CRT device. Comorbidities were more common in older patients (chronic kidney disease (CKD): 27.5% vs. 21.5%, p=0.029; atrial fibrillation (AF): 26.9% vs. 15.6%, pcardiac deaths in the older group (p=0.05). Patients ≥75years being alive after 1year had lower response rates, with chronic kidney disease (OR 0.46, pheart failure symptoms. As expected severe heart failure (NYHA IV) was a strong independent predictor of death (HR 1.95, p=0.01), whereas AF as underlying rhythm could be worked out as predictor for mortality especially in the younger patients (HR 2.31, p=0.002). Patients ≥75years of age receiving a CRT device do not have a higher perioperative mortality and complication rate although comorbidities (CKD and AF) occur more frequently. The absolute 1-year mortality is higher; nevertheless, the proportion of cardiac deaths is even lower in the older patients reflecting a benefit of CRT in this group.

    1990-01-01

    Food irradiation is at a political crossroad. In one direction, it is moving forward supported by overwhelming scientific evidence of its safety and benefits to economy and health. In the opposite direction, it threatens to be derailed by misleading claims about its safety and usefulness. Whether people will ultimately benefit from the use of irradiation to help fight serious food problems, or whether they will allow the technology to go to waste, will be determined by how successful people are in separating the facts from the fiction of food irradiation

    Science.gov (United States)

    Korman, M G

    1990-01-01

    The recent isolation and classification of the spiral gastric bacteria Helicobacter pylori has led to an explosion of worldwide research. The data strongly suggest that H. pylori is the causative agent for type-B active chronic gastritis. The role of H. pylori in duodenal ulcer awaits clarification, and, more importantly, potential treatment regimens need clear documentation and further detailed research. The past decade has revealed many intriguing facts about H. pylori infection. If, during the 1990s, eradication of H. pylori by means of appropriate and safe medication can lead to the control and prevention of gastroduodenal disease, then major clinical and economic benefits can be anticipated.

    2017-04-01

    Treating suicide as a social fact means disregarding its individual and dramatic dimensions. Sociologists do not reason on the basis of specific cases but by studying the variations, in space and time, of suicide rates. Their contribution relates essentially to a renewed perspective on society: suicide is in fact a very accurate indicator of the intensity and quality of the bonds which unite or isolate individuals in a society.

    1990-11-01

    The Pinellas Plant, near St. Petersburg, Florida, is wholly owned by the United States Government. It is operated for the Department of Energy (DOE) by GE Aerospace, Neutron Devices (GEND). This plant was built in 1956 to manufacture neutron generators, a principal component in nuclear weapons. The neutron generators built at Neutron Devices consist of a miniaturized linear ion accelerator assembled with the pulsed electrical power supplies required for its operation. Production of these devices has necessitated the development of several uniquely specialized areas of competence and supporting facilities. The ion accelerator, or neutron tube, requires ultra clean, high vacuum technology; hermetic seals between glass, ceramic, glass-ceramic, and metal materials; plus high voltage generation and measurement technology. The existence of these capabilities at Neutron Devices has led directly to the assignment of other weapon application products: the lightning arrester connector, specialty capacitor, vacuum switch, and crystal resonator. Other product assignments such as active and reserve batteries and the radioisotopically-powered thermoelectric generator evolved from the plant`s materials measurement and controls technologies which are required to ensure neutron generator life.

The third edition includes an additional chapter on audio-visual interactions and applications, plus more on applications throughout. Reviews of previous editions have characterized it as "an essential source of psychoacoustic knowledge," "a major landmark ," and a book that "without doubt will have a long-lasting effect on the standing and future evolution of this scientific domain."

  12. Considering FACTS in Optimal Transmission Expansion Planning

    Directory of Open Access Journals (Sweden)

    K. Soleimani

    2017-10-01

    Full Text Available The expansion of power transmission systems is an important part of the expansion of power systems that requires enormous investment costs. Since the construction of new transmission lines is very expensive, it is necessary to choose the most efficient expansion plan that ensures system security with a minimal number of new lines. In this paper, the role of Flexible AC Transmission System (FACTS devices in the effective operation and expansion planning of transmission systems is examined. Effort was taken to implement a method based on sensitivity analysis to select the optimal number and location of FACTS devices, lines and other elements of the transmission system. Using this method, the transmission expansion plan for a 9 and a 39 bus power system was performed with and without the presence of FACTS with the use of DPL environment in Digsilent software 15.1. Results show that the use of these devices reduces the need for new transmission lines and minimizes the investment cost.

    2017-03-01

    At a time of fake news, hacks, leaks, and unverified reports, many people are unsure whom to believe. How can we communicate in ways that make individuals question their assumptions and learn? My colleagues at The Hastings Center and many journalists and scientists are grappling with this question and have, independently, reached the same first step: recognize that facts can't be fully understood without probing their connection to values. "Explaining the basics is important, of course, but we also need to diversify our approach to the coverage of science-particularly as it intersects with the matrix of cultural, religious, social, and political values of our readers," said an article in Undark, an online magazine of science journalism. An editorial in Nature called for scientists to engage directly with citizens in debates over climate change and genome editing, noting that "the ethical issues can be critically dependent on the science, for example, in understanding where the boundaries between non-heritable and heritable genome modifications might be."

  20. John Searle on Institutional Facts

    Directory of Open Access Journals (Sweden)

    m Abdullahi

    2010-09-01

    Here we argue that the essence of institutional facts is status functions. Humans recognize these functions which contain a set of deontic powers through collective intentionality. Therefore, institutional facts are ontologically subjective and epistemologically objective. Nevertheless, objectivity of institutional facts totally depends on language which itself is a fundamental institution for other institutions.

  1. Gait analysis: clinical facts.

    Science.gov (United States)

    Baker, Richard; Esquenazi, Alberto; Benedetti, Maria G; Desloovere, Kaat

    2016-08-01

    Gait analysis is a well-established tool for the quantitative assessment of gait disturbances providing functional diagnosis, assessment for treatment planning, and monitoring of disease progress. There is a large volume of literature on the research use of gait analysis, but evidence on its clinical routine use supports a favorable cost-benefit ratio in a limited number of conditions. Initially gait analysis was introduced to clinical practice to improve the management of children with cerebral palsy. However, there is good evidence to extend its use to patients with various upper motor neuron diseases, and to lower limb amputation. Thereby, the methodology for properly conducting and interpreting the exam is of paramount relevance. Appropriateness of gait analysis prescription and reliability of data obtained are required in the clinical environment. This paper provides an overview on guidelines for managing a clinical gait analysis service and on the principal clinical domains of its application: cerebral palsy, stroke, traumatic brain injury and lower limb amputation.

  2. Strain: Fact or Fiction?

    Science.gov (United States)

    Heilbronner, Renée

    2017-04-01

    2017 marks the 50th anniversary of the publication of John Ramsay's well known textbook "Folding and Fracturing of Rocks" - ... and the 30th anniversary of the rejection of a rather less well known paper entitled "Strain: Fact or Fiction?" submitted by Renée Panozzo to the Journal of Structural Geology. The gist of the paper was simple and straight forward: it was argued that not every fabric that can be observed in deformed rocks is necessarily a measure of the amount of strain the rock incurred. A distinction was made between a general "fabric", i.e., the traceable geometry of grain boundaries, for example, and a so-called "strain fabric", i.e., the model geometry that would result from homogeneously straining an initially isotropic fabric and that would exhibit at least orthorhombic symmetry. To verify if a given fabric was indeed a strain fabric it was therefore suggested to use the SURFOR method (published by Panozzo) and to carry out a so-called strain test, i.e., a check of symmetry, before interpreting the results of a fabric analysis in terms of strain. The problem with the paper was that it was very obviously written out of frustration. The frustration came form having reviewed a number of manuscripts which tried to use the then novel SURFOR method for strain analysis without first checking if the the fabric was a indeed a "strain fabric" or not, and then blaming the SURFOR method for producing ambiguous results. As a result, the paper was not exactly well balanced and carefully thought out. It was considered "interesting but not scholarly" by one of the reviewers and down-right offensive by the second. To tell the truth, however, the paper was not formally rejected. The editor Sue Treagus strongly encouraged Panozzo to revise the paper, ... and 30 years later, I will follow her advise and offer a revised paper as a tribute to John Ramsay. To quote from the original manuscript: "We should be a little more impressed that strain works so well, and less

    Modern power electronic devices such as thyristors and GTOs have made it possible to design controllable network elements, which will play a considerable role in ensuring reliable economic operation of transmission systems as a result of their capability to rapidly change active and reactive power. A number of FACTS elements for high-speed active and reactive power control will be described. Control of power system fluctuations in meshed systems by modulation of active and reactive power will be demonstrated using a number of examples. (author) 7 refs., 11 figs.

    Directory of Open Access Journals (Sweden)

    Witjes Suzanne

    2012-02-01

    Full Text Available Abstract Background Acute lateral ankle ligament injuries are very common problems in present health care. Still there is no hard evidence about which treatment strategy is superior. Current evidence supports the view that a functional treatment strategy is preferable, but insufficient data are present to prove the benefit of external support devices in these types of treatment. The hypothesis of our study is that external ankle support devices will not result in better outcome in the treatment of acute ankle sprains, compared to a purely functional treatment strategy. Overall objective is to compare the results of three different strategies of functional treatment for acute ankle sprain, especially to determine the advantages of external support devices in addition to functional treatment strategy, based on balance and coordination exercises. Methods/design This study is designed as a randomised controlled multi-centre trial with one-year follow-up. Adult and healthy patients (N = 180 with acute, single sided and first inversion trauma of the lateral ankle ligaments will be included. They will all follow the same schedule of balancing exercises and will be divided into 3 treatment groups, 1. pressure bandage and tape, 2. pressure bandage and brace and 3. no external support. Primary outcome measure is the Karlsson scoring scale; secondary outcomes are FAOS (subscales, number of recurrent ankle injuries, Visual Analogue Scales of pain and satisfaction and adverse events. They will be measured after one week, 6 weeks, 6 months and 1 year. Discussion The ANKLE TRIAL is a randomized controlled trial in which a purely functional treated control group, without any external support is investigated. Results of this study could lead to other opinions about usefulness of external support devices in the treatment of acute ankle sprain. Trial registration Netherlands Trial Register (NTR: NTR2151

  5. Fake facts and alternative truths in medical research.

    Science.gov (United States)

    Hofmann, Bjørn

    2018-01-27

    Fake news and alternative facts have become commonplace in these so-called "post-factual times." What about medical research - are scientific facts fake as well? Many recent disclosures have fueled the claim that scientific facts are suspect and that science is in crisis. Scientists appear to engage in facting interests instead of revealing interesting facts. This can be observed in terms of what has been called polarised research, where some researchers continuously publish positive results while others publish negative results on the same issue - even when based on the same data. In order to identify and address this challenge, the objective of this study is to investigate how polarised research produce "polarised facts." Mammography screening for breast cancer is applied as an example. The main benefit with mammography screening is the reduced breast cancer mortality, while the main harm is overdiagnosis and subsequent overtreatment. Accordingly, the Overdiagnosis to Mortality Reduction Ratio (OMRR) is an estimate of the risk-benefit-ratio for mammography screening. As there are intense interests involved as well as strong opinions in debates on mammography screening, one could expect polarisation in published results on OMRR. A literature search identifies 8 studies publishing results for OMRR and reveals that OMRR varies 25-fold, from 0.4 to 10. Two experts in polarised research were asked to rank the attitudes of the corresponding authors to mammography screening of the identified publications. The results show a strong correlation between the OMRR and the authors' attitudes to screening (R = 0.9). Mammography screening for breast cancer appears as an exemplary field of strongly polarised research. This is but one example of how scientists' strong professional interests can polarise research. Instead of revealing interesting facts researchers may come to fact interests. In order to avoid this and sustain trust in science, researchers should disclose

    1994-01-01

    The invention concerns a proton therapy device using a proton linear accelerator which produces a proton beam with high energies and intensities. The invention lies in actual fact that the proton beam which is produced by the linear accelerator is deflected from 270 deg in its plan by a deflecting magnetic device towards a patient support including a bed the longitudinal axis of which is parallel to the proton beam leaving the linear accelerator. The patient support and the deflecting device turn together around the proton beam axis while the bed stays in an horizontal position. The invention applies to radiotherapy. 6 refs., 5 figs

    Purpose: To enhance the control accuracy of a thermonuclear power control device by feeding back electron temperature in addition to a thermonuclear power, thereby making the thermonuclear reactor power stably follow an objective value. Constitution: It is aimed at the fact that a high speed neutral particle incidence causes the increase in the electron temperature, and the neutral particle incidence responsive to the electron temperature is controlled by a high speed neutral particle incident device. Thus, the electron temperature is monitored, the thermonuclear power is monitored, and the control accuracy of the thermonuclear power control device is enhanced by employing a control system for feeding back these values.

    2015-08-01

    Monitoring health and fitness is emerging as an important benefit that smartphone users could expect from their mobile devices today. Rule of thumb calorie tracking and recommendation based on selective activity monitoring is widely available today, as both on-device and server based solutions. What is surprisingly not available to the users is a simple application geared towards quantitative fitness tracking. Such an application potentially can be a direct indicator of one's cardio-vascular performance and associated long term health risks. Since wearable devices with various inbuilt sensors like accelerometer, gyroscope, SPO2 and heart rate are increasingly becoming available, it is vital that the enormous data coming from these sensors be used to perform analytics to uncover hidden health and fitness associated facts. A continuous estimation of fitness level employing these wearable devices can potentially help users in setting personalized short and long-term exercise goals leading to positive impact on one's overall health. The present work describes a step in this direction. This work involves an unobtrusive method to track an individual's physical activity seamlessly, estimate calorie consumption during a day by mapping the activity to the calories spent and assess fitness level using heart rate data from wearable sensors. We employ a heart rate based parameter called Endurance to quantitatively estimate cardio-respiratory fitness of a person. This opens up avenues for personalization and adaptiveness by dynamically using individual's personal fitness data towards building robust modeling based on analytical principles.

    The aim of this chapter is to review the worldwide use of intrauterine devices (IUDs) for contraception and the long-term contraceptive efficacy and safety of copper-bearing IUDs. The TCu380A and Multiload Cu375 have a very low failure rate (0.2-0.5%) over 10 years. The main concerns of the use of IUDs are risk of pelvic inflammatory diseases and increased menstrual blood loss and irregular bleeding. Factors associated with an increase in risk of pelvic inflammatory diseases are discussed. Preventive measures can be taken with careful screening of eligible IUD users, technical training and adequate service facilities for provision of IUDs. Levonorgestrel-releasing IUDs have the benefit of reducing menstrual blood loss in addition to high contraceptive efficacy. The copper IUD is the most effective method for emergency contraception. It can prevent over 95% of unwanted pregnancies within 5 days of unprotected intercourse. Copyright 2002 Elsevier Science Ltd.

  19. Electromagnetic hypersensitivity: Fact or fiction?

    2012-01-01

    As the prevalence of wireless telecommunication escalates throughout the world, health professionals are faced with the challenge of patients who report symptoms they claim are connected with exposure to some frequencies of electromagnetic radiation (EMR). Some scientists and clinicians acknowledge the phenomenon of hypersensitivity to EMR resulting from common exposures such as wireless systems and electrical devices in the home or workplace; others suggest that electromagnetic hypersensitivity (EHS) is psychosomatic or fictitious. Various organizations including the World Health Organization as well as some nation states are carefully exploring this clinical phenomenon in order to better explain the rising prevalence of non-specific, multi-system, often debilitating symptoms associated with non-ionizing EMR exposure. As well as an assortment of physiological complaints, patients diagnosed with EHS also report profound social and personal challenges, impairing their ability to function normally in society. This paper offers a review of the sparse literature on this perplexing condition and a discussion of the controversy surrounding the legitimacy of the EHS diagnosis. Recommendations are provided to assist health professionals in caring for individuals complaining of EHS. - Highlights: ► Many people report symptoms when near devices emanating electromagnetic fields(EMF). ► Electromagnetic hypersensitivity (EHS) research has generated conflicting outcomes. ► Recent evidence suggests pathophysiological change in some individuals with EHS. ► EHS patients consistently report profound social and personal challenges. ► Clinicians need to be apprised of the EHS condition and potential interventions.

    2018-03-08

    Technologies for controlling mosquito vectors based on genetic manipulation and the release of genetically modified mosquitoes (GMMs) are gaining ground. However, concrete epidemiological evidence of their effectiveness, sustainability, and impact on the environment and nontarget species is lacking; no reliable ecological evidence on the potential interactions among GMMs, target populations, and other mosquito species populations exists; and no GMM technology has yet been approved by the WHO Vector Control Advisory Group. Our opinion is that, although GMMs may be considered a promising control tool, more studies are needed to assess their true effectiveness, risks, and benefits. Overall, several lines of evidence must be provided before GMM-based control strategies can be used under the integrated vector management framework. Copyright © 2018 Elsevier Ltd.

    International Nuclear Information System (INIS)

    1991-12-01

    The safety and benefits of foods processed by ionizing radiation are well documented. In an effort to provide governments, especially those of developing countries, with scientifically accurate information on issues of general interest to the public, the International Consultative Group on Food Irradiation (ICGFI), which was established under the aegis of the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO), and the IAEA, decided at its 7th Annual Meeting in Rome, Italy, on October 1990, to issue a series of ''Fact Sheets'' on the subject. ICGFI, an inter-governmental body with a membership of 37 governments, has as one of its mandates the function to provide information to Member States of the FAO, WHO, and IAEA and to the three organizations themselves on the safe and proper use of food irradiation technology. The Fact Sheets included here cover issues relating to: status and trends; scientific and technical terms; food irradiation and radioactivity; chemical changes in irradiated food; nutritional quality of irradiated foods; genetic studies; microbiological safety of irradiated food; irradiation and food safety; irradiation and food additives and residues; packaging of irradiated foods; safety of irradiation facilities; controlling the process; food irradiation costs; and irradiated foods and the consumer. The Fact Sheets have been separately indexed and included in the INIS Database under Reference Numbers 23011206-23011217, 23011319 and 23012743. The Fact Sheets were first issued by the ICGFI Secretariat (Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Vienna, Austria) in May 1991

  8. Objective and perceptual comparisons of two bluetooth hearing aid assistive devices.

    Science.gov (United States)

    Clark, Jackie L; Pustejovsky, Carmen; Vanneste, Sven

    2017-08-01

    With the advent of Bluetooth technology, many of the assistive listening devices for hearing have become manufacturer specific, with little objective information about the performance provided. Thirty native English-speaking adults (mean age 29.8) with normal hearing were tested pseudo-randomly with two major hearing aid manufacturers' proprietary Bluetooth connectivity devices paired to the accompanying manufacturer's specific hearing aids. Sentence recognition performance was objectively measured for each system with signals transmitted via a land-line to the same iPhone in two conditions. There was a significant effect of participant's performance according to listening condition. There was no significant effect between device manufacturers according to listening condition, but there was a significant effect in participant's perception of "quality of sound". Despite differences in signal transmission for each devise, when worn by participants both the systems performed equally. In fact, participants expressed personal preferences for specific technology that was largely due to their perceived quality of sound while listening to recorded signals. While further research is necessary to investigate other measures of benefit for Bluetooth connectivity devices, preliminary data suggest that in order to ensure comfort and compatibility, not only should objective measures of the patient benefit be completed, but also assessing the patient's perception of benefit is equally important. Implications for Rehabilitation All professionals who work with individuals with hearing loss, become aware of the differences in the multiple choices for assistive technology readily available for hearing loss. With the ever growing dispensing of Bluetooth connectivity devices coupled to hearing aids, there is an increased burden to determine whether performance differences could exist between manufacturers. There is a growing need to investigate other measures of benefit for Bluetooth

  14. Facing the Facts and Living our Values

    Science.gov (United States)

    Snieder, R.

    2009-05-01

    One of the major challenges for the 21st Century is to establish an energy system that is safe, affordable, sustainable, and environmentally responsible. With current reserves in coal and nonconventional oil, we will not run out of energy in the coming century, but we may pay a price with a climate that heats up with an unprecedented rate of change. Even with current technology, there is a wealth of information and solutions available, and we could benefit much by using this knowledge more effectively than we do now. An example is the McKinsey report on the cost of avoiding CO2 emissions (http://mckinsey.com/clientservice/ccsi/greenhousegas.asp). According to this analysis, the USA can avoid about 40% of its CO2 emissions at zero total cost. About 20% of those emissions can be saved by taking steps that save money and reduce energy consumption. In the process of working on these steps for reducing CO2 emissions, many jobs are created. The energy and climate challenge thus comes with new opportunities. Geoscientists can make a difference by talking about energy and climate, and by helping create awareness for the energy challenge and the associated opportunities. Scientists and engineers are, in general, loath to discuss the issue of values. Yet, despite the logical basis of science, our science and the personal views of scientists can help shape our societal values. This can happen, however, only when scientists articulate their values and stimulate their students and the public to make conscious choices what their values are. Education, whether it is in the classroom, at a community center, church, or service club, can play an important role in making the public aware of the facts that are important for the choices that we need to make at a personal and societal level for our energy use. In order to facilitate this type of communication I have created a public lecture that is available online (http://www.mines.edu/˜rsnieder/Global_Energy.html). As a geoscientist

  6. Generic Dynamic Environment Perception Using Smart Mobile Devices.

    Science.gov (United States)

    Danescu, Radu; Itu, Razvan; Petrovai, Andra

    2016-10-17

    The driving environment is complex and dynamic, and the attention of the driver is continuously challenged, therefore computer based assistance achieved by processing image and sensor data may increase traffic safety. While active sensors and stereovision have the advantage of obtaining 3D data directly, monocular vision is easy to set up, and can benefit from the increasing computational power of smart mobile devices, and from the fact that almost all of them come with an embedded camera. Several driving assistance application are available for mobile devices, but they are mostly targeted for simple scenarios and a limited range of obstacle shapes and poses. This paper presents a technique for generic, shape independent real-time obstacle detection for mobile devices, based on a dynamic, free form 3D representation of the environment: the particle based occupancy grid. Images acquired in real time from the smart mobile device's camera are processed by removing the perspective effect and segmenting the resulted bird-eye view image to identify candidate obstacle areas, which are then used to update the occupancy grid. The occupancy grid tracked cells are grouped into obstacles depicted as cuboids having position, size, orientation and speed. The easy to set up system is able to reliably detect most obstacles in urban traffic, and its measurement accuracy is comparable to a stereovision system.

    A device is designed for producing and confining highenergy plasma from which neutrons are generated in copious quantities. A rotating sheath of electrons is established in a radial electric field and axial magnetic field produced within the device. The electron sheath serves as a strong ionizing medium to gas introdueed thereto and also functions as an extremely effective heating mechanism to the resulting plasma. In addition, improved confinement of the plasma is obtained by ring magnetic mirror fields produced at the ends of the device. Such ring mirror fields are defined by the magnetic field lines at the ends of the device diverging radially outward from the axis of the device and thereafter converging at spatial annular surfaces disposed concentrically thereabout.

    A sealing device for minimising the leakage of toxic or radioactive contaminated environments through a biological shield along an opening through which a flexible component moves that penetrates the shield. The sealing device comprises an outer tubular member which extends over a length not less than the maximum longitudinal movement of the component along the opening. An inner sealing block is located intermediate the length of the component by connectors and is positioned in the bore of the outer tubular member to slide in the bore and effect a seal over the entire longitudinal movement of the component. The cross-section of the device may be circular and the block may be of polytetrafluoroethylene or of nylon impregnated with molybdenum or may be metallic. A number of the sealing devices may be combined into an assembly for a plurality of adjacent longitudinally movable components, each adapted to sustain a tensile load, providing the various drives of a master-slave manipulator.

  10. Potential Benefits of Manmade Opals Demonstrated for First Time (Fact Sheet)

    Energy Technology Data Exchange (ETDEWEB)

    2012-06-01

    NREL experiments show that disordered inverse opals significantly scatter and trap near-infrared light, with possible impact on optoelectronic materials. Inverse opals, familiar in the form of brilliantly colored opal gemstones, are a class of materials that has astounding optical properties. Scientists have been exploring the ability of inverse opals to manipulate light in the hopes of harnessing this capacity for advanced technologies such as displays, detectors, lasers, and photovoltaics. A research group at the National Renewable Energy Laboratory (NREL) discovered that man-made inverse opal films containing significant morphological disorder exhibit substantial light scattering, consequently trapping wavelengths in the near-infrared (NIR), which is important to a number of technologies. This discovery is the first experimental evidence to validate a 2005 theoretical model predicting the confinement of light in such structures, and it holds great promise for improving the performance of technologies that rely on careful light control. This breakthrough also makes possible optoelectronic technologies that use a range of low-cost molecular and semiconductor species that otherwise absorb light too weakly to be useful. The disordered inverse opal architecture validates the theoretical model that predicts the diffusion and confinement of light in such structures. Electrochemically deposited CdSe inverse opal films containing significant morphological disorder exhibit substantial light scattering and consequent NIR light trapping. This discovery holds promise for NIR light management in optoelectronic technologies, particularly those involving weakly absorbing molecular and semiconductor photomaterials.

    Disclosed is a fuel handling guide tube centering device for use in nuclear reactors during fuel assembly handling operations. The device comprises an outer ring secured to the flange of a nuclear reactor pressure vessel, a rotatable table rotatably coupled to the outer ring, and a plurality of openings through the table. Truncated locating cones are positioned in each of the openings in the table, and the locating cones center the guide tube during fuel handling operations. The openings in the table are located such that each fuel assembly in the nuclear core may be aligned with one of the openings by a suitable rotation of the table. The locating cones thereby provide alignment between the fuel handling mechanism located in the guide tube and the individual fuel assemblies of the cone. The need for a device to provide alignment is especially critical for floating nuclear power plants, where wave motion may exist during fuel handling operations. 5 claims, 4 figures

  10. Motor Skill Depends on Knowledge of Facts

    Directory of Open Access Journals (Sweden)

    Jason eStanley

    2013-08-01

    Full Text Available Those in 20th century philosophy, psychology, and neuroscience who have discussed the nature of skilled action have, for the most part, accepted the view that being skilled at an activity is independent of knowing facts about that activity, i.e. that skill is independent of knowledge of facts. In this paper we question this view of motor skill. We begin by situating the notion of skill in historical and philosophical context. We use the discussion to explain and motivate the view that motor skill depends upon knowledge of facts. This conclusion seemingly contradicts well-known results in cognitive science. It is natural, on the face of it, to take the case of H.M., the seminal case in cognitive neuroscience that led to the discovery of different memory systems, as providing powerful evidence for the independence of knowledge and skill acquisition. After all, H.M. seems to show that motor learning is retained even when previous knowledge about the activity has been lost. Improvements in skill generally require increased precision of selected actions, what we call motor acuity. Motor acuity may indeed not require propositional knowledge and has direct parallels with perceptual acuity. We argue, however, that reflection on the specifics of H.M.’s case, as well as other research on the nature of skill, indicates that learning to become skilled at a motor task, for example, tennis depends also on knowledge-based selection of the right actions. Thus skilled activity requires both acuity and knowledge, with both increasing with practice. The moral of our discussion ranges beyond debates about motor skill; we argue that it undermines any attempt to draw a distinction between practical and theoretical activities. While we will reject the independence of skill and knowledge, our discussion leaves open several different possible relations between knowledge and skill. Deciding between them is a task to be resolved by future research.

    Results published in the mid-1970s from the National Institute of Nutrition (NIN) in India showed increased numbers of polyploid cells in rats, mice, monkeys and malnourished children fed irradiated wheat products. This fact sheet considers the validity of these results. A large number of independent studies have been subsequently performed, and in none of these have results been obtained that support the NIN findings. The conclusion is that there is no evidence to link the consumption of irradiated food with any mutagenic effect. 3 refs

    Risk, as commonly understood, is a complex melange of facts, values, and fears. While this complexity of public risk perception is now broadly recognized, its implications are insufficiently explored. Public risk perceptions offer p poor guide for public policymaking. Popular assessments of risk are tainted by misinformation and unreliable heuristics. While subjective considerations, often called values, play a role in public perception of risk, those 'values' are often inappropriate for government decisionmaking. Reliance on public perceptions of risk means more premature deaths. Public risk perception also is systematically skewed contrary to the interests of the disadvantaged. Strict probabilistic risk measures generally provide a superior guide for government regulatory policy

In order to assess the benefits of this proposal, four nonlinear circuits composed of piecewise linear modelled devices are analysed to determine their multiple operating points. The results show that HCM can find multiple solutions within a single homotopy trajectory. Furthermore, we take advantage of the fact that homotopy trajectories are PWL curves meant to replace the multidimensional interpolation and fine tuning stages of the path tracking algorithm with a simple and highly accurate procedure based on the parametric straight line equation.

    BACKGROUND Many beliefs about obesity persist in the absence of supporting scientific evidence (presumptions); some persist despite contradicting evidence (myths). The promulgation of unsupported beliefs may yield poorly informed policy decisions, inaccurate clinical and public health recommendations, and an unproductive allocation of research resources and may divert attention away from useful, evidence-based information. METHODS Using Internet searches of popular media and scientific literature, we identified, reviewed, and classified obesity-related myths and presumptions. We also examined facts that are well supported by evidence, with an emphasis on those that have practical implications for public health, policy, or clinical recommendations. RESULTS We identified seven obesity-related myths concerning the effects of small sustained increases in energy intake or expenditure, establishment of realistic goals for weight loss, rapid weight loss, weight-loss readiness, physical-education classes, breast-feeding, and energy expended during sexual activity. We also identified six presumptions about the purported effects of regularly eating breakfast, early childhood experiences, eating fruits and vegetables, weight cycling, snacking, and the built (i.e., human-made) environment. Finally, we identified nine evidence-supported facts that are relevant for the formulation of sound public health, policy, or clinical recommendations. CONCLUSIONS False and scientifically unsupported beliefs about obesity are pervasive in both scientific literature and the popular press. (Funded by the National Institutes of Health.) PMID:23363498

  3. The Early Universe. Facts and Fiction.

    Science.gov (United States)

    Börner, Gerhard

    In this corrected and enlarged edition of Börner's well respected textbook, you will find an up-to-date account of the interplay between particle physics and astrophysics upon which modern cosmology is founded. The author describes some of the theories which have been developed to model the fundamental interaction of elementary particles in the extremely high temperatures of the early universe, taking care to distinguish facts and wellestablished results from hypotheses and speculations. The three parts of the book discuss the standard hot big bang model of the early universe, the basic ideas of the standard and the grand unified theories of elementary particles, and the influence of dark matter of the large- scale evolution of structure. In addition to making some minor corrections, the author has added an appendix presenting new results and an updated bibliography. Two main groups of readers are addressed: research students in astronomy can use this book to understand the impact of elementary particle theory on cosmology, while research students in particle physics can use it to acquaint themselves with the basic facts of cosmology. The book is written carefully enough to appeal also to a wider audience of physicists.

    The Quick Facts and Trends module is part of a suite of Clean Air Markets-related tools that are accessible at http://camddataandmaps.epa.gov/gdm/index.cfm. The Quick Facts and Trends module provides charts and graphs depicting national trends in emissions and heat input. The user can view, for example, data pertaining to the top annual and ozone season emitters of a selected pollutant, the number of units and facilities in a particular state, and trends in sulfur dioxide, nitrogen oxide and carbon dioxide emissions.EPA's Clean Air Markets Division (CAMD) includes several market-based regulatory programs designed to improve air quality and ecosystems. The most well-known of these programs are EPA's Acid Rain Program and the NOx Programs, which reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)-compounds that adversely affect air quality, the environment, and public health. CAMD also plays an integral role in the development and implementation of the Clean Air Interstate Rule (CAIR).

    Dietary guidelines indicate that to get a proper nutrition is recommended eating 3 or more servings per day of whole grain. However, the recommendation is little known in the Spanish population, and almost the entire population doesn't fulfill it. Therefore, the aim of this review is to analyze the nutritional and health benefits associated with the consumption of whole grain cereals and the potential benefits related to the meeting of this guideline. Literature search regarding the topic. Whole grain cereals are rich in carbohydrates, fiber, vitamins and minerals, and its contribution to the average diet helps to achieve current recommended intakes and nutritional goals, so its consumption in the recommended amount supposes a nutritional benefit. Moreover, several studies indicate that increased consumption of whole grain cereal is associated with protection against various chronic degenerative diseases (cardiovascular, diabetes, cancer and metabolic syndrome), assisting in the maintenance of digestive health and body weight. These results may be due to the contribution of nutrients, fiber and phytochemicals of these foods, as well as the displacement of the diet of other products with a less desirable nutritional profile, taking into account the composition of the average Spanish diet. In fact, the consumption of whole grain cereals has been linked with a possible improvement in the intestinal microbiota and antioxidant protection. In spite of these advantages, cereal consumption is looked with suspicion by many individuals, especially those concerned about weight control and additional benefits associated to consumption of whole grain cereals are not known. Whole grain cereals should be daily consumed in amounts of 3 or more servings/day, to achieve the nutritional and health benefits described in numerous investigations. More outreach is needed to ensure that the guideline is known and it's applied. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA

    Protrusions and recesses are formed to a vacuum vessel and toroidal magnetic coils, and they are engaged. Since the vacuum vessel is generally supported firmly by a rack or the like by support legs, the toroidal magnetic field coils can be certainly supported against tumbling force. Then, there can be attained strong supports for the toroidal magnetic field coils, in addition to support by wedges on the side of inboard and support by share panels on the side of outboard, capable of withstanding great electromagnetic forces which may occur in large-scaled next-generation devices. That is, toroidal magnetic field coils excellent from a view point of deformation and stress can be obtained, to provide a thermonuclear device of higher reliability. (N.H.)

    Purpose: To provide excellent electric properties and high reliability in a thermonuclear device by improving a current collecting board connected to a coil device. Constitution: A current collecting board element perforated with an opening for enserting a connecting terminal is sized to be inserted into a plating tank, and is surface treated in the plating tank. Only the current collecting board element preferably surface treated is picked up. A plurality of such current collecting board elements are connected and welded to form a large current collecting board. In this manner, the current collecting board having several m 2 to several ten order m 2 in area can be obtained as preferably surface treated at the connecting terminal hole. The current collecting board element can be determined in shape with the existing facility without increasing the size of a surface treating tank. (Kamimura, M.)

  15. Fact and fictions in FX arbitrage processes

    Science.gov (United States)

    Cross, Rod; Kozyakin, Victor

    2015-02-01

    The efficient markets hypothesis implies that arbitrage opportunities in markets such as those for foreign exchange (FX) would be, at most, short-lived. The present paper surveys the fragmented nature of FX markets, revealing that information in these markets is also likely to be fragmented. The "quant" workforce in the hedge fund featured in The Fear Index novel by Robert Harris would have little or no reason for their existence in an EMH world. The four currency combinatorial analysis of arbitrage sequences contained in [1] is then considered. Their results suggest that arbitrage processes, rather than being self-extinguishing, tend to be periodic in nature. This helps explain the fact that arbitrage dealing tends to be endemic in FX markets.

  18. Group C. Initiator paper. Periodontal regeneration--fact or fiction?

    Science.gov (United States)

    Bartold, P M

    2015-01-01

    Numerous techniques have been tried and tested to regenerate tissues lost to periodontal disease. While there has been some success to date, more work is required to move this to a reliable and clinically predictable procedure. Much of the future success for such treatments will rely largely on our understanding of the biology of both developmental and regenerative processes. Nonetheless, despite the noble goal of periodontal regeneration, the relevance of re-creation of a connective tissue attachment has been questioned. Since formation of a long junctional epithelial attachment to the tooth following a variety of periodontal treatment procedures has been shown to be no more susceptible to further breakdown than a non-diseased site, the question arises as to what purpose do we seek the ultimate outcome of periodontal regeneration? The answer lies in the "fact and fiction" of periodontal regeneration. There is no doubt that the regenerative procedures that have been developed can be shown to be biologically successful at the histological level. Furthermore, the results of periodontal regeneration (particularly guided tissue regeneration) have been stable over the long term (at least up to 10 years). However, the techniques currently under use which show the greatest promise (guided tissue regeneration and growth factors) are still clinically unpredictable because of their highly technique-sensitive nature. In addition, whether the slight clinical improvements offered by these procedures over routine open flap debridement procedures are of cost or patient benefit with regards to improved periodontal health and retention of teeth remains to be established. The next phase in regenerative technologies will undoubtedly involve a deeper understanding of the molecular signaling (both intra- and extra-cellular) and cellular differentiation processes involved in the regenerative processes. So in answer to the question of whether periodontal regeneration is fact or fiction

  20. Disentangling the benefits of sex.

    Science.gov (United States)

    Roze, Denis

    2012-01-01

    Understanding the evolutionary advantage of sexual reproduction remains one of the most fundamental questions in evolutionary biology. Most of the current hypotheses rely on the fact that sex increases genetic variation, thereby enhancing the efficiency of natural selection; an important body of theoretical work has defined the conditions under which sex can be favoured through this effect. Over the last decade, experimental evolution in model organisms has provided evidence that sex indeed allows faster rates of adaptation. A new study on facultatively sexual rotifers shows that increased rates of sex can be favoured during adaptation to new environmental conditions and explores the cause of this effect. The results provide support for the idea that the benefits of increasing genetic variation may compensate for the short-term costs of sexual reproduction.

    Thermoelectric (TE) devices heat, cool, and generate electricity when a temperature differential is provided between the two module faces. In cooperation with NASA, Chico, California-based United States Thermoelectric Consortium Inc. (USTC) built a gas emissions analyzer (GEA) for combustion research. The GEA precipitated hydrocarbon particles, preventing contamination that would hinder precise rocket fuel analysis. The USTC research and design team uses patent-pending dimple, pin-fin, microchannel and microjet structures to develop and design heat dissipation devices on the mini-scale level, which not only guarantee high performance of products, but also scale device size from 1 centimeter to 10 centimeters. USTC continues to integrate the benefits of TE devices in its current line of thermal management solutions and has found the accessibility of NASA technical research to be a valuable, sustainable resource that has continued to positively influence its product design and manufacturing

  8. Science fiction/science fact: medical genetics in news stories.

    Science.gov (United States)

    Petersen, Alan; Anderson, Alison; Allan, Stuart

    2005-12-01

    News media coverage of biotechnology issues offers a rich source of fictional portrayals, with stories drawing strongly on popular imagery and metaphors in descriptions of the powers and dangers of biotechnology. This article examines how science fiction metaphors, imagery and motifs surface in British newspaper (broadsheet and tabloid) coverage of medical genetic issues, focusing on press reporting of two recent highly publicised news media events; namely, the Hashmi and Whitaker families' plights to use stem cells from a 'perfectly matched sibling' for the treatment of their diseased children. It is concerned in particular with the extent to which journalists' use of certain literary devices encourages preferred formulations of medical genetics, and thereby potentially shapes public deliberation about scientific developments and their consequences for society. Understanding how science fiction sustains science fact, and vice versa, and how the former is portrayed in news media, it is argued, would thus seem to be crucial in the effort to understand why people respond so strongly to biotechnologies, and what they imagine their consequences to be.

  18. FACT. Bokeh alignment for Cherenkov telescopes

    Energy Technology Data Exchange (ETDEWEB)

    Mueller, Sebastian Achim [ETH Zurich (Switzerland); Buss, Jens [TU Dortmund (Germany)

    2016-07-01

    Imaging Atmospheric Cherenkov Telescopes (IACTs) need fast and large imaging optics to map the faint Cherenkov light emitted in cosmic ray air showers onto their image sensors. Segmented reflectors are inexpensive, lightweight and offer good image quality. However, alignment of the mirror facets remains a challenge. A good alignment is crucial in IACT observations to separate gamma rays from hadronic cosmic rays. We present a simple, yet extendable method, to align segmented reflectors using their Bokeh. Bokeh alignment does not need a star or good weather nights but can be done anytime, even during the day. Bokeh alignment optimizes the facet orientations by comparing the segmented reflector's Bokeh to a predefined template. The Bokeh is observed using the out of focus image of a nearby point like light source in a distance of about ten times the focal lengths. We introduce Bokeh alignment on segmented reflectors and present its use on the First Geiger-mode Avalanche Cherenkov Telescope (FACT) on Canary Island La Palma, as well as on the Cherenkov Telescope Array (CTA) Medium Size Telescope (MST) prototype in Berlin Adlershof.

  19. Transgene flow: Facts, speculations and possible countermeasures

    Science.gov (United States)

    Ryffel, Gerhart U

    2014-01-01

    Convincing evidence has accumulated that unintended transgene escape occurs in oilseed rape, maize, cotton and creeping bentgrass. The escaped transgenes are found in variant cultivars, in wild type plants as well as in hybrids of sexually compatible species. The fact that in some cases stacked events are present that have not been planted commercially, implies unintended recombination of transgenic traits. As the consequences of this continuous transgene escape for the ecosystem cannot be reliably predicted, I propose to use more sophisticated approaches of gene technology in future. If possible GM plants should be constructed using either site-directed mutagenesis or cisgenic strategies to avoid the problem of transgene escape. In cases where a transgenic trait is needed, efficient containment should be the standard approach. Various strategies available or in development are discussed. Such a cautious approach in developing novel types of GM crops will enhance the sustainable potential of GM crops and thus increase the public trust in green gene technology. PMID:25523171

  1. Knowledge as Fact-Tracking True Belief

    Directory of Open Access Journals (Sweden)

    Fred Adams

    Full Text Available ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A. Barker, and Robert Nozick, we develop a tracking analysis of knowing according to which a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading to skepticism, and validates the epistemic closure thesis that correct inferences from known premises yield knowledge of the conclusions. We discuss the plausible views of Ted Warfield and Branden Fitelson regarding cases of knowledge acquired via inference from false premises, and we show how our sensitivity analysis can account for such cases. We present arguments designed to discredit putative counterexamples to sensitivity analyses recently proffered by Tristan Haze, John Williams and Neil Sinhababu, which involve true statements made by untrustworthy informants and strange clocks that sometimes display the correct time while running backwards. Finally, we show that in virtue of employing the paradox-free subjunctive conditionals codified by Relevance Logic theorists instead of the paradox-laden subjunctive conditionals codified by Robert Stalnaker and David Lewis.

  2. Energy: facts and figures in 2006

    The consumption of final energy in France in 2006 increased slightly on the whole (+0.6%) and in all sectors except the industry (-0.7%). The final energy consumption is defined as the difference between the total consumption of primary energy and the consumption of the energy production sector. The evolution of the consumption of final energy is different according to the type of energy: +4.1% for coal (due to the strong demand in the iron and steel industry), +3.6% for renewable energies (due to specific development programs), +1.5% for electrical power and no change for oil and natural gas. Despite high prices, sales of car fuels rose by 0.4%, this figure hides the fact that the sales of fuels for diesel cars rose by 2.7% (because of the growing population of diesel cars) while those of grade petrol kept on plummeting (-5.9%). It is important to note that the releases of CO 2 due to energy went down by -1.4% in 2006. The energy bill increased by +18.5% to fetch 46.2*10 9 euros despite the decrease of the imported volumes. This articles details the energy figures for France in 2006 and sheds light particularly on 3 aspects: first, the annual trends in energy since 1973, secondly, the energy bill and thirdly the figures for electricity, natural gas, solid mineral fuels, hydrocarbons and renewable sources of energy.

    Baad-Hansen, Lene; Benoliel, Rafael

    2017-06-01

    Definition and taxonomy This review deals with neuropathic pain of traumatic origin affecting the trigeminal nerve, i.e. painful post-traumatic trigeminal neuropathy (PTTN). Symptomatology The clinical characteristics of PTTN vary considerably, partly due to the type and extent of injury. Symptoms involve combinations of spontaneous and evoked pain and of positive and negative somatosensory signs. These patients are at risk of going through unnecessary dental/surgical procedures in the attempt to eradicate the cause of the pain, due to the fact that most dentists only rarely encounter PTTN. Epidemiology Overall, approximately 3% of patients with trigeminal nerve injuries develop PTTN. Patients are most often female above the age of 45 years, and both physical and psychological comorbidities are common. Pathophysiology PTTN shares many pathophysiological mechanisms with other peripheral neuropathic pain conditions. Diagnostic considerations PTTN may be confused with one of the regional neuralgias or other orofacial pain conditions. For intraoral PTTN, early stages are often misdiagnosed as odontogenic pain. Pain management Management of PTTN generally follows recommendations for peripheral neuropathic pain. Expert opinion International consensus on classification and taxonomy is urgently needed in order to advance the field related to this condition.

    1997-01-01

    The present invention provides a thermonuclear device, in which integrity of a measuring device is kept, the reactor wall temperature and wear of armour materials are monitored accurately even under intense radiation rays, so that the flow rate of coolants and plasma power can be controlled by using the signals. Infrared rays generated from the surface of the armour materials disposed on a first wall are detected to measure the reactor wall temperature. Coolant flow rate and plasma power are controlled based on the obtained reactor wall temperature. In addition, infrared rays generated from the back of the armour materials are detected to obtain the surface temperature in order to avoid intense radiation rays from plasmas. The coolant flow rate and the plasma power are controlled based on the obtained temperature on the surface of the reactor thereby controlling the temperature of the first wall and the armour material to 300degC or lower in a case of the first wall made of stainless steel and 1000degC or lower in a case of the armour material made of graphite.

    KAUST Repository

    Krüger, Jens J.

    2014-01-01

    In computer science in general and in particular the field of high performance computing and supercomputing the term scalable plays an important role. It indicates that a piece of hardware, a concept, an algorithm, or an entire system scales with the size of the problem, i.e., it can not only be used in a very specific setting but it\\'s applicable for a wide range of problems. From small scenarios to possibly very large settings. In this spirit, there exist a number of fixed areas of research on scalability. There are works on scalable algorithms, scalable architectures but what are scalable devices? In the context of this chapter, we are interested in a whole range of display devices, ranging from small scale hardware such as tablet computers, pads, smart-phones etc. up to large tiled display walls. What interests us mostly is not so much the hardware setup but mostly the visualization algorithms behind these display systems that scale from your average smart phone up to the largest gigapixel display walls.

  6. Thermonuclear device

    Kobayashi, Noriyuki.

    1994-01-01

    In a thermonuclear device, a protrusion is protruded the direction to point X of a separatrix of magnetic fields and oscillated. Further, a protrusion continuous in the toroidal direction is formed from a first wall toward the point X and the position for the point X is oscillated in perpendicular to the divertor. If moving widths are compared for the shape of each of the divertors, it is longest in the case of the protruded shape, and a sweeping speed in a collision region is greatest in a case of the protruded shape and the moving width can be increased for the moving time and moving width of the identical point X. Accordingly, fluctuation of the magnetic fields of the divertor coils can relatively be reduced. A high heat receiving portion of the surface of the divertor can be made sufficiently great and moved rapidly with less oscillation width for the point X, thereby enabling to suppress AC loss of superconductors of toroidal coils and keep a stable superconductive state. Further, the divertor can be kept from melting, to attain a reliable thermonuclear device. (I.S.)

    Hess, Dean R

    2013-10-01

    Evidence-based medicine (EBM) is the integration of individual clinical expertise with the best available research evidence from systematic research and the patient's values and expectations. A hierarchy of evidence can be used to assess the strength upon which clinical decisions are made. The efficient approach to finding the best evidence is to identify systematic reviews or evidence-based clinical practice guidelines. Respiratory therapies that evidence supports include noninvasive ventilation for appropriately selected patients, lung-protective ventilation, and ventilator discontinuation protocols. Evidence does not support use of weaning parameters, albuterol for ARDS, and high frequency oscillatory ventilation for adults. Therapy with equivocal evidence includes airway clearance, selection of an aerosol delivery device, and PEEP for ARDS. Although all tenets of EBM are not universally accepted, the principles of EBM nonetheless provide a valuable approach to respiratory care practice.

    Device-to-Device (D2D) communication will become a key feature supported by next generation cellular networks, a topic of enormous importance to modern communication. Currently, D2D serves as an underlay to the cellular network as a means to increase spectral efficiency. Although D2D communication brings large benefits in terms of system capacity, it also causes interference as well as increased computation complexity to cellular networks as a result of spectrum sharing. Thus, efficient resource management must be performed to guarantee a target performance level of cellular communication.This

    2013-12-01

    The current study used a randomized controlled trial to compare the effects of a practice-based intervention and a mnemonic strategy intervention on the retention and application of single-digit multiplication facts with 90 third- and fourth-grade students with math difficulties. Changes in retention and application were assessed separately using one-way ANCOVAs in which students' pretest scores were included as the covariate. Students in the practice-based intervention group had higher retention scores (expressed as the total number of digits correct per minute) relative to the control group. No statistically significant between-group differences were observed for application scores. Practical and theoretical implications for interventions targeting basic multiplication facts are discussed. © 2013.

    2010-08-01

    Coronary artery disease is the major cause of death in the western world. The formation and rapid progression of atheromatous plaques can lead to serious cardiovascular events in patients with atherosclerosis. The better understanding, in recent years, of the mechanisms leading to atheromatous plaque growth and disruption and the availability of powerful HMG CoA-reductase inhibitors (statins) has permitted the consideration of plaque regression as a realistic therapeutic goal. This article reviews the existing evidence underpinning current therapeutic strategies aimed at achieving atherosclerotic plaque regression. In this review we also discuss imaging modalities for the assessment of plaque regression, predictors of regression and whether plaque regression is associated with a survival benefit.

    2017-09-01

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. Belgium consists of three regions: Brussels, Flanders and Wallonia, each with much autonomy in determining renewable support policies, except for support to offshore wind and hydro power which fall under the competence of the federal government. Electricity from renewable sources is promoted at regional and federal levels mainly through a quota system based on the trade of certificates, complemented by regional support measures. In the three regions small PV installations benefit from net metering. The federal government supports renewable heating and cooling by way of a tax deduction on investment costs. The main support scheme for renewable energy sources used in transport is a quota system under the competence of the federal government

  17. Ionizing radiation: benefits vs. risks

    International Nuclear Information System (INIS)

    Wagner, H.N. Jr.

    1986-01-01

    No one has been identifiably injured by radiation within the levels set by the NCRP and ICRP in 1934. This fact and the level of natural radiation (average dose 102 millirems/year) help provide standards against which the authors can view the relative increases in exposure from manmade sources of radiation. Because one person in five in the US will die of cancer from all causes, it is impossible to detect small increases in some types of cancer from radiation. A valid assumption is that any exposure to radiation carries some possibility of harm and should be kept below the level of the expected benefits. More is known about radiation toxicity than about any other potentially toxic substances. An obstacle to progress in the use of radioactive materials in biology and medicine is an exaggerated impression by the public of the risk of radiation. Several studies indicate that the public perceives the risk of radiation to be the greatest of all societal risks and at times does not distinguish peaceful from military uses of radiation. It behooves scientists and physicians to inform the public about the benefits as well as the risks of procedures involving radiation

  18. Does retrieval practice enhance learning and transfer relative to restudy for term-definition facts?

    Science.gov (United States)

    Pan, Steven C; Rickard, Timothy C

    2017-09-01

    In many pedagogical contexts, term-definition facts that link a concept term (e.g., "vision") with its corresponding definition (e.g., "the ability to see") are learned. Does retrieval practice involving retrieval of the term (given the definition) or the definition (given the term) enhance subsequent recall, relative to restudy of the entire fact? Moreover, does any benefit of retrieval practice for the term transfer to later recall of the definition, or vice versa? We addressed those questions in 4 experiments. In each, subjects first studied term-definition facts and then trained on two thirds of the facts using multiple-choice tests with feedback. Half of the test questions involved recalling terms; the other half involved recalling definitions. The remaining facts were either not trained (Experiment 1) or restudied (Experiments 2-4). A 48-hr delayed multiple-choice (Experiments 1-2) or short answer (Experiments 3a-4) final test assessed recall of all terms or all definitions. Replicating and extending prior research, retrieval practice yielded improved recall and positive transfer relative to no training. Relative to restudy, however, retrieval practice consistently enhanced subsequent term retrieval, enhanced subsequent definition retrieval only after repeated practice, and consistently yielded at best minimal positive transfer in either direction. Theoretical and practical implications are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    2016-09-01

    Full Text Available The aim of this study is to present a comprehensive comparison and assessment of the damping function improvement of power system oscillation for the multiple damping controllers using the simultaneously coordinated design based on Power System Stabilizer (PSS and Flexible AC Transmission System (FACTS devices. FACTS devices can help in the enhancing the stability of the power system by adding supplementary damping controller to the control channel of the FACTS input to implement the task of Power Oscillation Damping (FACT POD controller. Simultaneous coordination can be performed in different ways. First, the dual coordinated designs between PSS and FACTS POD controller or between different FACTS POD controllers are arranged in a multiple FACTS devices without PSS. Second, the simultaneous coordination has been extended to triple coordinated design among PSS and different FACTS POD controllers. The parameters of the damping controllers have been tuned in the individual controllers and coordinated designs by using a Chaotic Particle Swarm Optimization (CPSO algorithm that optimized the given eigenvalue-based objective function. The simulation results for a multi-machine power system show that the dual coordinated design provide satisfactory damping performance over the individual control responses. Furthermore, the triple coordinated design has been shown to be more effective in damping oscillations than the dual damping controllers.

  1. Numerical simulation of left ventricular assist device implantations: comparing the ascending and the descending aorta cannulations.

    Bonnemain, Jean; Malossi, A Cristiano I; Lesinigo, Matteo; Deparis, Simone; Quarteroni, Alfio; von Segesser, Ludwig K

    2013-10-01

    In this work we present numerical simulations of continuous flow left ventricle assist device implantation with the aim of comparing difference in flow rates and pressure patterns depending on the location of the anastomosis and the rotational speed of the device. Despite the fact that the descending aorta anastomosis approach is less invasive, since it does not require a sternotomy and a cardiopulmonary bypass, its benefits are still controversial. Moreover, the device rotational speed should be correctly chosen to avoid anomalous flow rates and pressure distribution in specific location of the cardiovascular tree. With the aim of assessing the differences between these two approaches and device rotational speed in terms of flow rate and pressure waveforms, we set up numerical simulations of network of one-dimensional models where we account for the presence of an outflow cannula anastomosed to different locations of the aorta. Then, we use the resulting network to compare the results of the two different cannulations for several stages of heart failure and different rotational speed of the device. The inflow boundary data for the heart and the cannulas are obtained from a lumped parameters model of the entire circulatory system with an assist device, which is validated with clinical data. The results show that ascending and descending aorta cannulations lead to similar waveforms and mean flow rate in all the considered cases. Moreover, regardless of the anastomosis region, the rotational speed of the device has an important impact on wave profiles; this effect is more pronounced at high RPM. Copyright © 2013 IPEM.

  2. Greenhouse Gas Management Program Overview (Fact Sheet)

    Energy Technology Data Exchange (ETDEWEB)

    2011-11-01

    Program fact sheet highlighting federal requirements for GHG emissions management, FEMP services to help agencies reduce emissions, and additional resources. The U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP) assists Federal agencies with managing their greenhouse gas (GHG) emissions. GHG management entails measuring emissions and understanding their sources, setting a goal for reducing emissions, developing a plan to meet this goal, and implementing the plan to achieve reductions in emissions. FEMP provides the following services to help Federal agencies meet the requirements of inventorying and reducing their GHG emissions: (1) FEMP offers one-on-one technical assistance to help agencies understand and implement the Federal Greenhouse Gas Accounting and Reporting Guidance and fulfill their inventory reporting requirements. (2) FEMP provides training, tools, and resources on FedCenter to help agencies complete their annual inventories. (3) FEMP serves a leadership role in the interagency Federal Working Group on Greenhouse Gas Accounting and Reporting that develops recommendations to the Council on Environmental Quality (CEQ) for the Federal Greenhouse Gas Accounting and Reporting Guidance. (4) As the focus continues to shift from measuring emissions (completing inventories) to mitigating emissions (achieving reductions), FEMP is developing a strategic planning framework and resources for agencies to prioritize among a variety of options for mitigating their GHG emissions, so that they achieve their reduction goals in the most cost-effective manner. These resources will help agencies analyze their high-quality inventories to make strategic decisions about where to use limited resources to have the greatest impact on reducing emissions. Greenhouse gases trap heat in the lower atmosphere, warming the earth's surface temperature in a natural process known as the 'greenhouse effect.' GHGs include carbon dioxide (CO{sub 2

    A reluctance device comprises two or more phases, each of which has a rotor mounted for rotation within a tubular member and an annular stator positioned externally of the tubular member. The rotor and the internal surface of the tubular member are each provided with aligned, axially spaced apart annular arrays of teeth, the teeth on the rotor confronting those on the tubular member in radially spaced apart relationship. The stator encloses a coil which, when electrically energised, creates a plurality of magnetic flux paths each of which extends radially between the rotor and stator via the confronting teeth and the tubular member, and axially along both the rotor and the portion of the stator located radially outwardly of the coil. The portion of the tubular member intermediate the teeth thereon is provided with a non-magnetic insert in order to resist the axial passage of magnetic flux therethrough. In one of the claims, the tubular member comprises a portion of a nuclear reactor which is adapted to contain a reactor control rod, the rotor constituting a portion of the drive mechanism for the control rod contained in operation within the tubular member.

    Full Text Available In ESL context, learners may have less attention to the use of conjunctions. In fact, the use of conjunctions in L2 learners’ writings is crucial since it is one type of cohesive devices. This paper aims to find the cohesive devices of conjunctions used by the learners. Through analyzing eight learners’ essays, the writer found 37 forms and 12 types of conjunctions in the learners’ essays. The most significant form of conjunctions was‘and’, whereas the most significant types of conjunction as ‘addition’. Moreover, the writer also found some inappropriate use of conjunctions, which are grouped into five, namely, unclassified, wrong mechanism, L1 interference, wrong forms of conjunctions, and grammatical error.   DOI: https://doi.org/10.24071/llt.2015.180106

    Roque, Nelson A; Boot, Walter R

    2018-02-01

    Mobile device proficiency is increasingly required to participate in society. Unfortunately, there still exists a digital divide between younger and older adults, especially with respect to mobile devices (i.e., tablet computers and smartphones). Training is an important goal to ensure that older adults can reap the benefits of these devices. However, efficient/effective training depends on the ability to gauge current proficiency levels. We developed a new scale to accurately assess the mobile device proficiency of older adults: the Mobile Device Proficiency Questionnaire (MDPQ). We present and validate the MDPQ and a short 16-question version of the MDPQ (MDPQ-16). The MDPQ, its subscales, and the MDPQ-16 were found to be highly reliable and valid measures of mobile device proficiency in a large sample. We conclude that the MDPQ and MDPQ-16 may serve as useful tools for facilitating mobile device training of older adults and measuring mobile device proficiency for research purposes.

    2004-11-15

    Significant progress in the field of VaD resulted from publication of the NINIDS-AIREN Diagnostic Criteria for VaD (G.C. Roman, T.K. Tatemichi, T. Erkinjuntti, et al., Vascular dementia (VaD): diagnostic criteria for research studies. Report of the NINDS-AIREN International Workshop. Neurology 43 (1993) 250-260). Epidemiological studies confirmed the importance of VaD as the second most common cause of dementia in the elderly, representing 15-20% of all cases of dementia. In Europe and North America, Alzheimer's disease (AD) predominates over VaD in a 2:1 ratio; in contrast, in Japan and China VaD accounts for almost 50% of all dementias. Case-control studies have identified risk factors for VaD including ageing, hypertension, diabetes mellitus, hyperlipidemia, recurrent stroke, cardiac disease, smoking, sleep apnea, and more recently, hyperhomocysteinemia, among others. Hypertension treatment may prevent VaD and AD. This finding has enormous importance from the Public Health viewpoint to decrease the future number of patients with dementia in the elderly. Along with advances in the field of VaD came a number of controversies and damaging misconceptions and myths. Myth no. 1--Vascular dementia is a non-entity: The false idea that VaD does not exist is particularly destructive because it creates the perspective that VaD is unworthy of study or research. A condition that either does not exist or represents only a minute proportion of all cases of dementia in the elderly, lacks public health relevance and becomes a low priority for research by funding agencies and industry. In fact, vascular brain lesions are the commonest and most important component of dementia in the elderly. Myth no. 2--Vascular dementia is so difficult to diagnose that only experts can recognize and identify it accurately: VaD does exist and the diagnosis of post-stroke VaD, in particular is straightforward. Most cases fulfill NINDS-AIREN criteria for probable VaD; i.e., (1) there is acute onset

    Full Text Available Abstract Background Biomedical research is changing due to the rapid accumulation of experimental data at an unprecedented scale, revealing increasing degrees of complexity of biological processes. Life Sciences are facing a transition from a descriptive to a mechanistic approach that reveals principles of cells, cellular networks, organs, and their interactions across several spatial and temporal scales. There are two conceptual traditions in biological computational-modeling. The bottom-up approach emphasizes complex intracellular molecular models and is well represented within the systems biology community. On the other hand, the physics-inspired top-down modeling strategy identifies and selects features of (presumably essential relevance to the phenomena of interest and combines available data in models of modest complexity. Results The workshop, "ESF Exploratory Workshop on Computational disease Modeling", examined the challenges that computational modeling faces in contributing to the understanding and treatment of complex multi-factorial diseases. Participants at the meeting agreed on two general conclusions. First, we identified the critical importance of developing analytical tools for dealing with model and parameter uncertainty. Second, the development of predictive hierarchical models spanning several scales beyond intracellular molecular networks was identified as a major objective. This contrasts with the current focus within the systems biology community on complex molecular modeling. Conclusion During the workshop it became obvious that diverse scientific modeling cultures (from computational neuroscience, theory, data-driven machine-learning approaches, agent-based modeling, network modeling and stochastic-molecular simulations would benefit from intense cross-talk on shared theoretical issues in order to make progress on clinically relevant problems.

    Text-mining algorithms make mistakes in extracting facts from natural-language texts. In biomedical applications, which rely on use of text-mined data, it is critical to assess the quality (the probability that the message is correctly extracted) of individual facts--to resolve data conflicts and inconsistencies. Using a large set of almost 100,000 manually produced evaluations (most facts were independently reviewed more than once, producing independent evaluations), we implemented and teste...

    Developers and system operators face a number of technical, economic and environmental challenges when planning remote, offshore wind farms. While AC connection solutions using dynamic reactive power compensation are usually used to meet connection requirements during rapid load changes and during fault conditions in the grid, high voltage DC (HVDC) transmission is occasionally the only feasible option for connection of a wind farm if transmission distances are significant. This paper described the commercial and technical benefits of using flexible AC transmission systems (FACTS) such as the Static Var Compensator (SVC) and static synchronous compensator (STATCOM) to meet grid connection requirements. Case studies were used to demonstrate system stability performance enhancements. Proposed system operation methodologies and control strategies were described. System operations and dynamic performances during generation variations were illustrated. Applications of line-commutated converter HVDC and voltage source converter HVDCs for connecting large offshore wind farms to the grid were also described. A case study of a hybrid HVDC comprised of a LCC HVDC and a SVC-based STATCOM for connecting a 500 MW wind farm was presented. System performances during onshore 3-phase AC faults were studied and strategies for the coordination of the HVDC system were proposed and validated by simulations. Various simulation results between different configurations of the systems showed that while the SVC solution was easier to install and operate, the LCC HVDC system had lower power losses. Capital costs of the LCC HVDC system for large wind farms were also lower, as fewer cables were used. 11 refs., 5 figs.

  20. Metabolic effects of oral contraceptives: fact vs. fiction.

    Science.gov (United States)

    1996-01-01

    Many studies show that low-dose OCs have little adverse effect on carbohydrate metabolism and are safe for healthy women, women with a history of gestational diabetes, and women with insulin-dependent diabetes to use. In fact, large epidemiologic studies indicate that OCs, even the high-dose OCs (=or 50 mcg) for long periods, do not increase the risk of diabetes. There is some evidence indicating that OC use does not heighten the progression of diabetic retinopathy, nephropathy, or cardiovascular complications among women with insulin-dependent diabetes. There is no significant difference in carbohydrate metabolism among the different OC formulations. One must carefully consider the risk:benefit ratio of OC use in diabetic women since pregnancy has serious consequences for both mother and fetus. Cardiovascular complications in OC users do not originate from atherogenesis. The androgenic properties of the progestin in low-dose OCs and their effect on lipids are inconsequential for later development of coronary atherogenesis. The estrogen in OCs may protect against atherosclerosis, particularly among women at high risk of atherosclerosis. Former OC users are not at an increased risk of coronary heart disease, stroke, or other heart disease. Lipid changes in OC users tend to remain within the normal range and return to pretreatment values during the pill-free week. All OCs suppress gonadotropins and subsequent ovarian androgen production. They partially suppress androgen production by the adrenals as well. This suppression from two fronts outweighs any androgenic action of the progestin alone. Further, androgenic action probably cannot overpower the estrogen effect. The dose of levonorgestrel used in OCs is too low to express androgenic effects. Since OCs suppress androgen production, all OCs tend to improve acne. OCs reduce free testosterone and increase sex hormone binding globulin levels.

  1. New FACTS Equipment in an Enhanced Version of Smart Grids. The Magnetic Gate

    Directory of Open Access Journals (Sweden)

    Julio Enrique Posada C.

    2014-08-01

    Full Text Available This work is a qualitative proposal of a new FACTS device, which aims to repower the "Smart Grids", to a higher level. The existing FACTS that are covering the role of power flow control have the disadvantages of the use of electronic devices, and generate excessive heat and harmonics injected into the network. These devices are expensive and their regulation is binary: zero flow or total flow. This proposal offers a more versatile power flow control from zero to one hundred percent of its nominal capacity. Smart grids will no longer need to have a Relay Counseling Center, and the communication by pilot wire or other means available will be enough to control and protect the network. Therefore, due to fewer crossed and analyzed data, the laborious task of considering whether an event is really a failure, will be less complicated and will be carried out more quickly. In combination with phase measurement units (PMUs for each MAG, approximation techniques will not be necessary to estimate the variations caused by the dynamics of the demand, because the MAG is operating in "floating mode" as discussed further below. The network automatically and gradually rearranges these variations. Incomplete observation could be used for measuring voltage and current signals of the network in some specific points in the network.

    The detrimental impact of long duration space flight on physiological systems necessitates the development of exercise countermeasures to protect work capabilities in gravity fields of Earth, Moon and Mars. The respective rates of physiological deconditioning for different organ systems during space flight has been described as a result of data collected during and after missions on the Space Shuttle, International Space Station, Mir, and bed rest studies on Earth. An integrated countermeasure that simulates the body's hydrostatic pressure gradient, provides mechanical stress to the bones and muscles, and stimulates the neurovestibular system may be critical for maintaining health and well being of crew during long-duration space travel, such as a mission to Mars. Here we review the results of our studies to date of an integrated exercise countermeasure for space flight, lower body negative pressure (LBNP) treadmill exercise, and potential benefits of its application to athletic training on Earth. Additionally, we review the benefits of Lower Body Positive Pressure (LBPP) exercise for rehabilitation of postoperative patients. Presented first are preliminary data from a 30-day bed rest study evaluating the efficacy of LBNP exercise as an integrated exercise countermeasure for the deconditioning effects of microgravity. Next, we review upright LBNP exercise as a training modality for athletes by evaluating effects on the cardiovascular system and gait mechanics. Finally, LBPP exercise as a rehabilitation device is examined with reference to gait mechanics and safety in two groups of postoperative patients.

  4. Retrieval Practice, with or without Mind Mapping, Boosts Fact Learning in Primary School Children

    Ritchie, Stuart J.; Della Sala, Sergio; McIntosh, Robert D.

    2013-01-01

    Retrieval practice is a method of study in which testing is incorporated into the learning process. This method is known to facilitate recall for facts in adults and in secondary-school-age children, but existing studies in younger children are somewhat limited in their practical applicability. In two studies of primary school-age children of 8–12 years, we tested retrieval practice along with another study technique, mind mapping, which is more widely-used, but less well-evidenced. Children studied novel geographical facts, with or without retrieval practice and with or without mind mapping, in a crossed-factorial between-subjects design. In Experiment 1, children in the retrieval practice condition recalled significantly more facts four days later. In Experiment 2, this benefit was replicated at one and five weeks in a different, larger sample of schoolchildren. No consistent effects of mind mapping were observed. These results underline the effectiveness of retrieval practice for fact learning in young children. PMID:24265738

    Today's children have more opportunities than ever before to learn from interactive technology, yet experimental research assessing the efficacy of children's learning from interactive media in comparison to traditional learning approaches is still quite scarce. Moreover, little work has examined the efficacy of using touch-screen devices for research purposes. The current study compared children's rate of learning factual information about animals during a face-to-face instruction from an adult female researcher versus an analogous instruction from an interactive device. Eighty-six children ages 4 through 8 years (64% male) completed the learning task in either the Face-to-Face condition ( n = 43) or the Interactive Media condition ( n = 43). In the Learning Phase of the experiment, which was presented as a game, children were taught novel facts about animals without being told that their memory of the facts would be tested. The facts were taught to the children either by an adult female researcher (Face-to-Face condition) or from a pre-recorded female voice represented by a cartoon Llama (Interactive Media condition). In the Testing Phase of the experiment that immediately followed, children's memory for the taught facts was tested using a 4-option forced-choice paradigm. Children's rate of learning was significantly above chance in both conditions and a comparison of the rates of learning across the two conditions revealed no significant differences. Learning significantly improved from age 4 to age 8, however, even the preschool-aged children performed significantly above chance, and their performance did not differ between conditions. These results suggest that, interactive media can be equally as effective as one-on-one instruction, at least under certain conditions. Moreover, these results offer support for the validity of using interactive technology to collect data for research purposes. We discuss the implications of these results for children's learning

    Progesterone receptor (PR) agonists (progestins) and antagonists are developed for female contraceptives. However, non-contraceptive applications of newer progestins and PR modulators are being given more attention. The newer PR agonists including drospirenone, nomegestrol, trimegestone, dienogest and nestorone are being evaluated as contraceptives with health benefits because of their unique pharmacological properties. The selective PR modulators (SPRM; PR antagonists with PR agonistic properties) are under development not only for emergency contraception but also for other health benefits such as the treatment of endometritis and leiomyoma. After searching the literature from PubMed, clinicaltrials.gov and patent database, this review focuses on the effects and mechanisms of these progestins, and SPRMs as contraceptives with other health benefits. PR agonists and antagonists that have novel properties may generate better contraceptive effects with other health benefits.

    The report was prepared as part of the Ohio River Basin Energy Study (ORBES), a multidisciplinary policy research program. The study region consists of all of Kentucky, most of West Virginia, and substantial portions of Illinois, Indiana, Ohio, and Pennsylvania. By 1988, coal-fired electrical generating capacity in the region is expected to total over 100,000 MWe, versus about 11,000 MWe projected for nuclear-fueled capacity by that year. Thus, the ORBES emphasis was on coal-fired generation. This report attempts to fill in some of the gaps in the relative lack of emphasis on the risks and benefits of nuclear electricity production in the study region. It covers the following topics: (1) basic facts about radiation, (2) an overview of the current regulatory framework of the nuclear industry, (3) health risks associated with electricity production by LWRs, (4) the risks of nuclear proliferation, terrorism, and sabotage, (5) comparative economics and healthy risks of coal versus nuclear, and (6) the March 1979 accident at Three Mile Island

  5. Safety lock for radiography exposure device

    International Nuclear Information System (INIS)

    Gaines, T.M.

    1982-01-01

    A safety lock for securing a radiation source in a radiography exposure device is disclosed. The safety lock prevents the inadvertent extension of the radiation source from the exposure device. The exposure devices are used extensively in industry for nondestructive testing of metal materials for defect. Unnecessary exposure of the radiographer or operator occurs not infrequently due to operator's error in believing that the radiation source is secured in the exposure device when, in fact, it is not. The present invention solves this problem of unnecessary exposure by releasingly trapping the radiation source in the shield of the radiography exposure device each time the source is retracted therein so that it is not inadvertently extended therefrom without the operator resetting the safety lock, thereby releasing the radiation source. Further, the safety lock includes an indicator which indicates when the source is trapped in the exposure device and also when it is untrapped. The safety lock is so designed that it does not prevent the return of the source to the trapped, shielded position in the exposure device. Further the safety lock includes a key means for locking the radiation source in the trapped position. The key means cannot be actuated until said radiation source is in said trapped position to further insure the safety lock cannot be inadvertently locked with the source untrapped and thus still extendable from the exposure device

  6. Representation of multiplication facts--evidence for partial verbal coding.

    Moeller, Korbinian; Klein, Elise; Fischer, Martin H; Nuerk, Hans-Christoph; Willmes, Klaus

    2011-07-08

    The current view in numerical cognition research is that multiplication facts are stored and retrieved in a phonological code. Consistent with this view, it was found that multiplication could be impaired by a phonological but not by a visuo-spatial loading task. However, because the authors used an active production task, it remained unclear whether concurrent articulation impaired either access to multiplication facts or their retrieval. In the current study, we investigated the influence of concurrent articulation on multiplication fact knowledge without active production of multiplication results. In a number bisection task, number triplets, which are part of a multiplication table, were classified faster as being correctly bisected than other triplets. Interestingly, concurrent articulation led to a relative slowing of the multiplicative triplets which reduced the multiplicativity effect. This result indicates that concurrent articulation modulates access to phonologically stored multiplication facts and corroborates the notion of multiplication facts being represented in an at least partially verbal code.

    The First G-APD Cherenkov Telescope (FACT) demonstrates the usability of novel Geiger-mode operated Avalanche Photo Diodes (G-APD, often called SiPM) for Imaging Atmospheric Cherenkov Telescopes (IACT). The camera consists of 1440 pixels with dedicated electronics operating at 2 Giga samples per second. It is installed on the refurbished HEGRA telescope with a mirror area of ≈ 9.5m2 on the Canary Island La Palma. FACT is taking data almost every night since the camera was installed in October 2011. It was possible to improve the data taking efficiency to very high values due to the very stable and reliable operation. This also allows to operate FACT remotely without any need for operators on site. Even remote human intervention became less and less frequent over the years, allowing operation to become mostly automatic. FACT is monitoring the long-term behavior of some very-high energy variable extra-galactic sources with unparalleled sampling density as well as testing the behavior of the sensors under severe weather conditions. Due to the long exposure of FACT's G-APDs under strong moonlight conditions it was possible to evaluate the aging effects of G-APDs due to collected charge. No indication of aging was found. No external calibration device is needed to operate FACT since the properties of the sensors themselves allow for a high precision self-calibration of the camera.

  17. Admissions screening: clinical benefits.

    One thousand patients admitted to a 575-bed general hospital during a 6-month period each underwent 20 chemical and hematologic tests. The potential clinical benefit was assessed. There were 2223 abnormal results found; 675 were predicted on clinical assessment, 1325 did not yield new diagnoses, and the remaining 223 led to 83 new diagnoses in 77 patients. On critical evaluation of the new diagnoses, none were unequivocally beneficial to the patient. Up to 30 patients might have benefited had these abnormal findings been followed up diligently, 39 others had findings or diagnoses of no lasting significance, and in 14 patients asymptomatic mild biochemical diabetes was discovered. Although screening may reveal many abnormal test results, the clinical benefits are not impressive.

    Efficient transcription elongation from a chromatin template requires RNA polymerases (Pols) to negotiate nucleosomes. Our biochemical analyses demonstrate that RNA Pol I can transcribe through nucleosome templates and that this requires structural rearrangement of the nucleosomal core particle....... The subunits of the histone chaperone FACT (facilitates chromatin transcription), SSRP1 and Spt16, co-purify and co-immunoprecipitate with mammalian Pol I complexes. In cells, SSRP1 is detectable at the rRNA gene repeats.
