1984-04-01

A feasibility study of video tape recorder (VTR) modification to add the capability of data recording etc. was conducted. This system is an on-broad system to support Spacelab experiments as a dedicated video system and a dedicated data recording system to operate independently of the normal operation of the Orbiter, Spacelab and the other experiments. It continuously records the video image signals with the acquired data, status and operator's voice at the same time on one cassette video tape. Such things, the crews' actions, animals' behavior, microscopic views and melting materials in furnace, etc. are recorded. So, it is expected that experimenters can make a very easy and convenient analysis of the synchronized video, voice and data signals in their post flight analysis.

1981-01-01

The capabilities added to the Shuttle/Spacelab configuration by the addition of the Power Extension Package (PEP), the Power System (PS), and the Science and Applications Space Platforms (SASP) are reviewed with an emphasis on SASP. SASP are intended for placement in orbit by the Shuttle to test new instruments and systems, for clustering of instrumentation, and for servicing, refurbishment, repair, or augmentation by the Shuttle. The PEP permits extended stays in orbit (30 days), and the PS is an orbital solar array and energy storage system acting as a free flying spacecraft. The Shuttle can deliver payloads to the PS or attach to it for extension of the Spacelab operations. Applications of SASP for long term space-based biological experiments are outlined, and the fact that SASP do not increase the required Shuttle in-orbit time is stressed.

Spacelab 3's Fluid Experiment System, in which triglycine sulfate crystals were produced by a low temperature solution-growth technique, employs holography as its primary data-gathering system. This use of holography allows optical techniques which would be difficult to apply in orbit to be used after the holographic data is returned to ground laboratories, using an analysis of the reconstructed holographic image. The system used allows both single- and double-exposure holograms to be obtained in two separate orthogonal configurations.

Hye, A.

1984-01-01

Design features and test results of an oil-free compressor developed for Spacelab Mission-4 Refrigerator/Freezer are detailed. The compressor has four identical pistons activated by a common eccentric shaft, operated by a brushless dc motor at 1300 rpm. The stroke of each piston is 0.28 cm, with the piston ends connected to the shaft by means of sealed needle bearings, eliminating the ned for oil. The mass flow rates produced by the compressor are by over 100 percent higher compared to the original Amfridge unit. Test results show that the compressor can meet the Spacelab refrigerator/freezer requirements.

Spacelab Life Science -1 (SLS-1) was the first Spacelab mission dedicated solely to life sciences. The main purpose of the SLS-1 mission was to study the mechanisms, magnitudes, and time courses of certain physiological changes that occur during space flight, to investigate the consequences of the body's adaptation to microgravity and readjustment to Earth's gravity, and bring the benefits back home to Earth. The mission was designed to explore the responses of the heart, lungs, blood vessels, kidneys, and hormone-secreting glands to microgravity and related body fluid shifts; examine the causes of space motion sickness; and study changes in the muscles, bones, and cells. This photograph shows astronaut Rhea Seddon conducting an inflight study of the Cardiovascular Deconditioning experiment by breathing into the cardiovascular rebreathing unit. This experiment focused on the deconditioning of the heart and lungs and changes in cardiopulmonary function that occur upon return to Earth. By using noninvasive techniques of prolonged expiration and rebreathing, investigators can determine the amount of blood pumped out of the heart (cardiac output), the ease with which blood flows through all the vessels (total peripheral resistance), oxygen used and carbon dioxide released by the body, and lung function and volume changes. SLS-1 was launched aboard the Space Shuttle Orbiter Columbia (STS-40) on June 5, 1995.

Tollinger, D.; Williams, B. A.

1980-01-01

Biological models of hypogravity effects are described, including the cardiovascular-fluid shift, musculoskeletal, embryological and space sickness models. These models predict such effects as loss of extracellular fluid and electrolytes, decrease in red blood cell mass, and the loss of muscle and bone mass in weight-bearing portions of the body. Experimentation in Spacelab by the use of implanted electromagnetic flow probes, by fertilizing frog eggs in hypogravity and fixing the eggs at various stages of early development and by assessing the role of the vestibulocular reflex arc in space sickness is suggested. It is concluded that the use of small animals eliminates the uncertainties caused by corrective or preventive measures employed with human subjects.

Craft, H. G.; Lester, R. C.

1978-01-01

The nucleus of the approach to Spacelab Payload mission management is the establishment of a single point of authority for the entire payload on a given mission. This single point mission manager will serve as a 'broker' between the individual experiments and the STS, negotiating agreements by two-part interaction. The payload mission manager, along with a small support team, will represent the users in negotiating use of STS accommodations. He will provide the support needed by each individual experimenter to meet the scientific, technological, and applications objectives of the mission with minimum cost and maximum efficiency. The investigator will assume complete responsibility for his experiment hardware definition and development and will take an active role in the integration and operation of his experiment.

As the first long-term on-orbit spacelab of China, TianGong-1 will stay aloft for 2 years. Its failure risk subjected to Meteoroid and Orbital Debris(M/OD) is hundreds of times higher than the risk of Shenzhou-5, Shenzhou-6 or Shenzhou-7, so the special M/OD protection designs have been applied. In order to reduce the penetration risk of radiator tube, the design of radiator has been modified by placing the tube at the side of radiator plate, and the new design does not affect the thermal control system without adding the mass. Secondly, Whipple structure is adopted in the two sides and front of spacecraft against M/OD impact.

Schatte, C.; Grindeland, R.; Callahan, P.; Berry, W.; Funk, G.; Lencki, W.

1987-01-01

The flight of two squirrel monkeys and 24 rats on Spacelab-3 was the first mission to provide hands-on maintenance on animals in a laboratory environment. With few exceptions, the animals grew and behaved normally, were free of chronic stress, and differed from ground controls only for gravity dependent parameters. One of the monkeys exhibited symptoms of space sickness similar to those observed in humans, which suggests squirrel monkeys may be good models for studying the space adaptation syndrome. Among the wide variety of parameters measured in the rats, most notable was the dramatic loss of muscle mass and increased fragility of long bones. Other interesting rat findings were those of suppressed interferom production by spleen cells, defective release of growth hormone by somatrophs, possible dissociation of circadian pacemakers, changes in hepatic lipid and carbohydrate metabolism, and hypersensitivity of marrow cells to erythropoietin. These results portend a strong role for animals in identifying and elucidating the physiological and anatomical responses of mammals to microgravity.

2016-01-01

It is clear that technology is a key driver of economic growth. Much less clear is where new technologies are produced and how the geography of U.S. invention has changed over the last two hundred years. Patent data report the geography, history, and technological characteristics of invention. However, those data have only recently become available in digital form and at the present time there exists no comprehensive dataset on the geography of knowledge production in the United States prior to 1975. The database presented in this paper unveils the geography of historical patents granted by the United States Patent and Trademark Office (USPTO) from 1836 to 1975. This historical dataset, HistPat, is constructed using digitalized records of original patent documents that are publicly available. We describe a methodological procedure that allows recovery of geographical information on patents from the digital records. HistPat can be used in different disciplines ranging from geography, economics, history, network science, and science and technology studies. Additionally, it is easily merged with post-1975 USPTO digital patent data to extend it until today. PMID:27576103

1988-01-01

The changes in erythropoiesis in astronauts caused by weightlessness was experimentally studied during the Spacelab 1 flight. Immediately after landing showed a mean decrease of 9,3 percent in the four astronauts. Neither hyperoxia nor an increase in blood phosphate caused the decrease. Red cell survival time and iron incorporation postflight were not significantly different from their preflight levels. Serum haptoglobin did not decrease, indicating that intravascular hemolysis was not a major cause of red cell mass change. An increase in serum ferritin after the second day of flight may have been caused by red cell breakdown early in flight. The space flight-induced decrease in red cell mass may result from a failure of erythropoesis to replace cells destroyed by the spleen soon after weightlessness is attained.

The Spacelab IPS Star Simulator

Science.gov (United States)

Wessling, Francis C., III

The cost of doing business in space is very high. If errors occur while in orbit the costs grow and desired scientific data may be corrupted or even lost. The Spacelab Instrument Pointing System (IPS) Star Simulator is a unique test bed that allows star trackers to interface with simulated stars in a laboratory before going into orbit. This hardware-in-the loop testing of equipment on earth increases the probability of success while in space. The IPS Star Simulator provides three fields of view 2.55 x 2.55 degrees each for input into star trackers. The fields of view are produced on three separate monitors. Each monitor has 4096 x 4096 addressable points and can display 50 stars (pixels) maximum at a given time. The pixel refresh rate is 1000 Hz. The spectral output is approximately 550 nm. The available relative visual magnitude range is 2 to 8 visual magnitudes. The star size is less than 100 arc seconds. The minimum star movement is less than 5 arc seconds and the relative position accuracy is approximately 40 arc seconds. The purpose of this paper is to describe the LPS Star Simulator design and to provide an operational scenario so others may gain from the approach and possible use of the system.

Interim Report of the Astronomy Spacelab Payloads Study. Volume 2; Ultraviolet and Optical Astronomy

Science.gov (United States)

1975-01-01

The Space Shuttle will comprise NASA's primary transportation system into near-earth orbit during the 1980s. The Shuttle will provide the astronomical community with a major new capability to send a wide variety of instrumentation into orbit, to utilize it there under manned or automatic control for periods from seven to thirty days, and to return it to the ground. To this end the European Space Research Organization (ESRO) is developing Spacelab, an array of interchangeable components -pressurized manned modules, unpressurized pallets and related support systems - to be mounted in the Shuttle payload bay. Spacelab will offer important opportunities to carry out astronomical research with instruments optimized for specific objectives. With a high flight frequency and with the ability to modify or interchange telescopes and instruments between flights, one will not need to make rigid long-term commitments to specific and compromised telescope/instrument/ detector combinations as is the case for automated satellites. Observational techniques demanding the physical return of data and equipment - in particular the use of photographic film, instruments requiring tight calibration controls, cryogens, high-risk detectors and degradeable optical coatings -will open research areas not readily addressed by automated satellites. Although Shuttle flight duration will be limited to periods from seven to thirty days, substantial data can be obtained with a single instrument on short missions, if targets are carefully selected and prioritized, and a large number of instruments can be accommodated on a single flight. Important astronomical data are regularly obtained on sounding rocket flights of five minutes duration. Spacelab will provide far longer observing periods for large and small telescopes, with resources greatly exceeding those of sounding rockets, while retaining much of the sounding rocket philosophy in terms of instrument flexibility, simplicity, reliability

An interactive computer approach to performing resource analysis for a multi-resource/multi-project problem. [Spacelab inventory procurement planning

Science.gov (United States)

Schlagheck, R. A.

1977-01-01

New planning techniques and supporting computer tools are needed for the optimization of resources and costs for space transportation and payload systems. Heavy emphasis on cost effective utilization of resources has caused NASA program planners to look at the impact of various independent variables that affect procurement buying. A description is presented of a category of resource planning which deals with Spacelab inventory procurement analysis. Spacelab is a joint payload project between NASA and the European Space Agency and will be flown aboard the Space Shuttle starting in 1980. In order to respond rapidly to the various procurement planning exercises, a system was built that could perform resource analysis in a quick and efficient manner. This system is known as the Interactive Resource Utilization Program (IRUP). Attention is given to aspects of problem definition, an IRUP system description, questions of data base entry, the approach used for project scheduling, and problems of resource allocation.

Lange, R.D.; Andrews, R.B.; Gibson, L.A.; Congdon, C.C.; Wright, P.; Dunn, C.D.R.; Jones, J.B.

1987-01-01

Previous studies have shown that a decrease in red cell mass occurs in astronauts, and some studies indicate a leukocytosis occurs. A life science module housing young and mature rats was flown on shuttle mission Spacelab 3 (SL-3), and the results of hematology studies of flight and control rats are presented. Statistically significant increases in the hematocrit, red blood cell counts, and hemoglobin determinations, together with a mild neutrophilia and lymphopenia, were found in flight animals. No significant changes were found in bone marrow and spleen cell differentials or erythropoietin determinations. Clonal assays demonstrated an increased erythroid colony formation of flight animal bone marrow cells at erythropoietin doses of 0.02 and 1.0 U/ml but not 0.20 U/ml. These results agree with some but vary from other previously published studies. Erythropoietin assays performed by radioimmunoassay and clonal studies were performed for the first time

Correlation lifetimes of quiet and magnetic granulation from the SOUP instrument on Spacelab 2

Title, A.; Tarbell, T.; Topka, K.; Acton, L.; Duncan, D.; Ferguson, S.; Finch, M.; Frank, Z.; Kelly, G.; Lindgren, R.; Morrill, M.; Pope, T.; Reeves, R.; Rehse, R.; Shine, R.; Simon, G.; Harvey, J.; Leibacher, J.; Livingston, W.; November, L.; Zirker, J.

The time sequences of diffraction limited granulation images obtained by the Solar Optical Universal Polarimeter on Spacelab 2 are presented. The uncorrection autocorrelation limetime in magnetic regions is dominated by the 5-min oscillation. The removal of this oscillation causes the autocorrelation lifetime to increase by more than a factor of 2. The results suggest that a significant fraction of granule lifetimes are terminated by nearby explosions. Horizontal displacements and transverse velocities in the intensity field are measured. Lower limits to the lifetime in the quiet and magnetic sun are set at 440 s and 950 s, respectively.

Scientific management and implementation of the geophysical fluid flow cell for Spacelab missions

Science.gov (United States)

Hart, J.; Toomre, J.

1980-01-01

Scientific support for the spherical convection experiment to be flown on Spacelab 3 was developed. This experiment takes advantage of the zero gravity environment of the orbiting space laboratory to conduct fundamental fluid flow studies concerned with thermally driven motions inside a rotating spherical shell with radial gravity. Such a system is a laboratory analog of large scale atmospheric and solar circulations. The radial body force necessary to model gravity correctly is obtained by using dielectric polarization forces in a radially varying electric field to produce radial accelerations proportional to temperature. This experiment will answer fundamental questions concerned with establishing the preferred modes of large scale motion in planetary and stellar atmospheres.

Schmerling, E. R.

1975-01-01

The Space Shuttle will open a new era in the exploration of earth's near-space environment, where the weight and power capabilities of Spacelab and the ability to use man in real time add important new features. The Atmospheric, Magnetospheric, and Plasmas-in-Space project (AMPS) is conceived of as a facility where flexible core instruments can be flown repeatedly to perform different observations and experiments. The twin thrusts of remote sensing of the atmosphere below 120 km and active experiments on the space plasma are the major themes. They have broader implications in increasing our understanding of plasma physics and of energy conversion processes elsewhere in the universe.

We experimentally investigate an intermittent route to chaos in a photonic integrated circuit consisting of a semiconductor laser with time-delayed optical feedback from a short external cavity. The transition from a period-doubling dynamics to a fully-developed chaos reveals a stage intermittently exhibiting these two dynamics. We unveil the bifurcation mechanism underlying this route to chaos by using the Lang-Kobayashi model and demonstrate that the process is based on a phenomenon of attractor expansion initiated by a particular distribution of the local Lyapunov exponents. We emphasize on the crucial importance of the distribution of the steady-state solutions introduced by the time-delayed feedback on the existence of this intermittent dynamics.

To analyze the perception of primiparous women about prenatal care in Basic Health Units in a municipality in southern Brazil. This is a qualitative research from the perspective of Social Representation Theory, from the following question: How has been the pre-natal care for you? Eighteen pregnant women were interviewed. The analysis resulted in three categories: Expectation representation about prenatal care; Rescuing the care offered in prenatal consultation; Unveiling the (dis) satisfaction with prenatal consultation. The prenatal care was apprehended as an essential moment for safe pregnancy, although centered on the doctor's figure and guarantee access to early laboratory and imaging tests. On the other hand, dissatisfaction was revealed from the reception at the entrance to the health unit to the consultations access, although some statements suggest timely satisfaction. Prenatal care did not meet the specific expectations of the study group and unveiled that the nurse did not supply it, as a member of the multidisciplinary team. The organization of the nursing work process in primary care, related to prenatal care, needs to be revisited to promote the effectiveness of its actions.

Man in space - A time for perspective. [crew performance on Space Shuttle-Spacelab program

Science.gov (United States)

Winter, D. L.

1975-01-01

Factors affecting crew performances in long-term space flights are examined with emphasis on the Space Shuttle-Spacelab program. Biomedical investigations carried out during four Skylab missions indicate that initially rapid changes in certain physiological parameters, notably in cardiovascular response and red-blood-cell levels, lead to an adapted condition. Calcium loss remains a potential problem. Space Shuttle environmental control and life-support systems are described together with technology facilitating performance of mission objectives in a weightless environment. It is concluded that crew requirements are within the physical and psychological capability of astronauts, but the extent to which nonastronaut personnel will be able to participate without extensive training and pre-conditioning remains to be determined.

Ames Research Center's Life Sciences Division has developed and flown an extensive array of spaceflight experiment unique equipment (EUE) during the last decade of the twentieth century. Over this ten year span, the EUE developed at ARC supported a vital gravitational biology flight research program executed on several different platforms, including the Space Shuttle, Spacelab, and Space Station Mir. This paper highlights some of the key EUE elements developed at ARC and flown during the period 1990-1999. Resulting lessons learned will be presented that can be applied to the development of similar equipment for the International Space Station.

Data analysis unveils a new stylized fact in foreign currency markets

Science.gov (United States)

Nacher, J. C.; Ochiai, T.

2012-09-01

The search for stylized facts (i.e., simplified empirical facts) is of capital importance in econophysics because the stylized facts constitute the experimental empirical body on which theories and models should be tested. At the moment they are too few and this is an important limitation to the progress in the field. In this work, we unveil a new stylized fact, which consists of resistance effect and breaking-acceleration effect that implicitly requires a long memory feature in price movement. By analyzing a vast amount of historical data, we demonstrate that the financial market tends to exceed a past (historical) extreme price less often than expected by a classic short-memory model (e.g., Black-Scholes model). We call it resistance effect. However, when the market does it, we predict that the average volatility at that time point will be much higher (accelerates more). It means, in average, volatility accelerates more when the price breaks the highest (lowest) value. We refer to this as breaking-acceleration effect. These observed empirical facts are actually an effect which may arise from technical trading and psychological effects. Taken together, these results indicate that, beyond the predictive capability of this unveiled stylized fact, traditional short-memory models do not faithfully capture the market dynamics.

The Evolution of Spacelab Ultraviolet Astronomy Missions from OSS-3 through -7 to Astro-1

Science.gov (United States)

Gull, Theodore

2018-01-01

In the 1960s and 1970s, NASA was building towards a robust program in space astronomy. An evolutionary step from ground-based astronomy to space astronomy was human operation of space telescopes as astronomy in general evolved from astronomers directly at the telescope to application of computers and long distance communications to control to operate remote telescopes. Today ground-based telescopes and space observatories from cubesats to the Hubble Space Telescope and soon the James Webb Space Telescope are routinely operated remotely.In response to the Spacelab Announcement of Opportunity in the early 1980s, three ultraviolet experiments – the Hopkins Ultraviolet Telescope, the Ultraviolet Imaging Telescope and the Wisconsin Ultraviolet PhotoPolarimetry Experiment -- all instruments derived from multiple sounding rocket flights--were selected to fly as an integrated payload attached to a space shuttle. The justification for professional astronomers, both as Mission Specialists from the astronaut cadre and Payload Specialists from the instrument teams, was built to ensure key technical skills both of the science and the instruments. Bundled together as OSS-3 through -7 flights focused on Comet Halley, the experiments went through many changes and delays as a pathfinder for an anticipated series of attached astronomy payloads.By 1986, the five-flight mission had evolved into two missions, Astro-1 dedicated primarily to observe Halley’s Comet in early March 1986 and Astro-2 to fly about one year later. Due to the Challenger disaster 35 days before scheduled launch of Astro-1, the mission went through an initial cancellation and then re-scheduling once the instrument complement of Astro-1 was expanded to include Broad Band X-ray Telescope with emphasis on studying SN1987A. Ultimately Astro-1 flew in December 1990 partnered with an X-ray experiment focused on SN1987A.The nine-day mission was mostly successful despite multiple technical issues overcome by the NASA

Lettuce was grown in a space vegetable cultivation facility onboard the Tiangong Ⅱ Spacelab during October 18 to November 15, 2016, in order to testify the key cultivating technology in CELSS under spaceflight microgravity condition. Potable water was used for irrigation of rooting substrate and the SRF (slowly released fertilizer) offered mineral nutrition for plant growth. Water content and electric conductivity in rooting substrate were measured based on FDR(frequency domain reflectometry) principle applied first in spaceflight. Lettuce germinated with comparative growth vigor as the ground control, showing that the plants appeared to be not stressed by the spaceflight environment. Under microgravity, lettuce grew taller and showed deeper green color than the ground control. In addition, the phototropism of the on-orbit plants was more remarkable. The nearly 30-d spaceflight test verified the seed fixation technology and water& nutrition management technology, which manifests the feasibility of FDR being used for measuring moisture content and electric conductivity in rooting zone under microgravity. Furthermore, the edibility of the space-grown vegetable was proved, providing theoretical support for astronaut to consume the space vegetable in future manned spaceflight.

2018-02-21

Although Islam is the fastest growing religion worldwide, only few studies have investigated body image in Muslim women, and no study has investigated body checking. Therefore, the present study examined whether body image, body checking, and disordered eating differ between veiled and unveiled Muslim women, Christian women, and atheist women. While the groups did not differ regarding body dissatisfaction, unveiled Muslim women reported more checking than veiled Muslim and Christian women, and higher bulimia scores than Christian. Thus, prevention against eating disorders should integrate all women, irrespective of religious affiliation or veiling, with a particular focus on unveiled Muslim women.

Low power CAMAC and NIM modular systems for spaceflight use on Shuttle and Spacelab missions

Energy Technology Data Exchange (ETDEWEB)

Trainor, J.H.; Kaminski, T.J.; Ehrmann, C.H.

1977-02-01

The advent of the Shuttle launch vehicle and Spacelab have resulted in adequate weight and volume such that experiment electronics can be implemented at relatively low cost using spaceflight versions of CAMAC and NIM modules. Studies of 10 modules by manufacturers have shown that power reduction overall by a factor of approximately 3 can be accomplished. This is adequate both from the point of view of consumption and temperature rise in vacuum. Our studies have shown that a stock of approximately 45 module types is required and a listing is given. The changes required in these modules in order to produce spaceflight versions are described. And finally, the further studies, prototyping and testing leading to eventual flight qualification are described.

From Multilatina to Global Latina: Unveiling the corporate-level international strategy choices of Grupo Nutresa

Directory of Open Access Journals (Sweden)

MARIA A DE VILLA

Full Text Available Research on Multilatinas has underexplored multinationals from Colombia and their corporate-level international strategy choices to develop into Global Latinas. Building on interviews, documents, and archival data about Grupo Nutresa -Colombia's most international firm in manufactured goods-, this study unveils and discusses this firm's corporate-level international strategy choices between 1960 and 2014. A prevailing notion is that most multinationals from Latin America continue to target international operations to focus mainly on their home region through an export, multidomestic or transnational corporate-level international strategy. In contrast, data show that Grupo Nutresa chose to evolve through a sequential approach from an export to a transnational corporate-level international strategy while its international operations were able to transcend its home region to reach North America, Asia, Europe, Africa, and Oceania. These results add to international business research on emergent market multinational companies (EMNCs from Latin America by unveiling the corporate-level international strategy choices of a Colombian origin Multilatina that transformed into a Global Latina.

The Spacelab-Mir-1 (SLM-1) mission is the first docking of the Space Shuttle Atlantis (STS-71) with the Orbital Station Mir in June 1995. The SLM-1 "Greenhouse-2" experiment will utilize the Russian-Bulgarian-developed plant growth unit (Svet). "Greenhouse-2" will include two plantings (1) designed to test the capability of Svet to grow a crop of Superdwarf wheat from seed to seed, and (2) to provide green plant material for post-flight analysis. Protocols, procedures, and equipment for the experiment have been developed by the US-Russian science team. "Greenhouse-2" will also provide the first orbital test of a new Svet Instrumentation System (SIS) developed by Utah State University to provide near real time data on plant environmental parameters and gas-exchange rates. SIS supplements the Svet control and monitoring system with additional sensors for substrate moisture, air temperature, IR leaf temperature, light, oxygen, pressure, humidity, and carbon-dioxide. SIS provides the capability to monitor canopy transpiration and net assimilation of the plants growing in each vegetation unit (root zone) by enclosing the canopy in separate, retractable, ventilated leaf chambers. Six times during the seed-to-seed experiment, plant samples will be collected, leaf area measured, and plant parts fixed and/or dried for ground analysis. A second planting initiated 30 days before the arrival of a U.S. Shuttle [originally planned to be STS-71] is designed to provide green material at the vegetative development stage for ground analysis. [As this paper is being edited, the experiment has been delayed until after the arrival of STS-71.].

Importance of temperature control for HEFLEX, a biological experiment for Spacelab 1. [plant gravitational physiology study

Science.gov (United States)

Chapman, D. K.; Brown, A. H.

1979-01-01

The importance of temperature control to HEFLEX, a Spacelab experiment designed to measure kinetic properties of Helianthis nutation in a low-g environment, is discussed. It is argued that the development of the HEFLEX experiment has been severely hampered by the inadequate control of ambient air temperature provided by the spacecraft module design. A worst case calculation shows that delivery of only 69% of the maximum yield of useful data from the HEFLEX system is guaranteed; significant data losses from inadequate temperature control are expected. The magnitude of the expected data losses indicates that the cost reductions associated with imprecise temperature controls may prove to be a false economy in the long term.

The effect of exposure to microgravity on pituitary gland was investigated by examining cells isolated from anterior pituitaries of rats flown on the 7-day Spacelab 3 mission and, subsequently, cultured for 6 days. Compared with ground controls, flight cells contained more intracellular growth hormone (GH); however, the flight cells released less GH over the 6-day culture period and after implantation into hypophysectomized rats than did the control cells. Compared with control rats, glands from large rats (400 g) contained more somatotrophs (44 percent compared with 37 percent in control rats); small rats (200 g) showed no difference. No major differences were found in the somatotroph ultrastructure (by TEM) or in the pattern of the immunoactive GH variants. However, high-performance liquid chromatography fractionation of culture media indicated that flight cells released much less of a biologically active high-molecular weight GH variant, suggesting that space flight may lead to secretory dysfunction.

Effects of rectilinear acceleration, caloric and optokinetic stimulation of human subjects in the Spacelab D-1 mission

Wetzig, J.; von Baumgarten, R.

A set of vestibular experiments was performed during the course of the German Spacelab D-1 mission from 30 October to 6 November 1985 by a consortium of experimenters from various european countries. Similar to the Spacelab SL-1 mission all of the scientific crew members were theoretically and practically trained for the experiments. Baseline measurements for all tests were collected 113, 86, 44, 30 and 18 days prior to the mission and compared with data taken inflight, on the landing day and the consecutive 7 to 14 days. The hardware comprised mainly a motordriven accelerating platform, the SPACE SLED, and the vestibular helmet, a multi-purpose instrument in support of a variety of vestibular experiments including air-calorisation of the ears, optokinetic stimulation pattern presentation and optical and nystagmographic recording of eye movements. Measurements of the threshold for the perception of detection of whole body movement did not reveal any dramatic changes in the 2 measured axes inflight when compared to preflight values. Early postflight values show a significantly elevated threshold for all axes in 3 out of 4 subjects. The caloric nystagmus, already found during the SL-1 mission, was confirmed on all three tested subjects during the D-1 mission. It's amplitude and in some instances it's direction were influenced by horizontal acceleration on the SLED. The amplitude of optokinetic nystagmus increased when subjects were allowed to free-float over that seen when subjects were fixed. Stimulation of the neck receptors by roll movements of the body against the fixated head resulted in illusory object motion to the contralateral side. Torsional movements of the eyes during such neck receptor stimulation was present inflight and postflight, while it had not been observed preflight. Most results point to a reduction of otolithic effects in favour of visual and proprioceptive influences for spatial orientation.

The transition of new technology to solve today`s problems

Extensive research has been conducted in the development of methods to predict the degradation of F-44 in storage. The Low Pressure Reactor (LPR) has greatly enhanced the stability prediction capabilities necessary to make informed decisions concerning aviation fuel in storage. This technique has in the past been primarily used for research purposes. The Naval Air Warfare Center, Aircraft Division, Trenton, NJ, has used this technique successfully to assist the Defense Fuel Supply Center, Cameron Station, Alexandria, VA, in stability assessments of F-44. The High Performance Liquid Chromatography/Electrochemical Detector (HPLC/EC) antioxidant determination technique has also aided in making stability predictions by establishing the amount of inhibitor currently in the product. This paper will address two case studies in which the above new technology was used to insure the rapid detection and diagnosis of today`s field and logistic problems.

Image motion compensation on the Spacelab 2 Solar Optical Universal Polarimeter /SL2 SOUP/

Science.gov (United States)

Tarbell, T. D.; Duncan, D. W.; Finch, M. L.; Spence, G.

1981-01-01

The SOUP experiment on Spacelab 2 includes a 30 cm visible light telescope and focal plane package mounted on the Instrument Pointing System (IPS). Scientific goals of the experiment dictate pointing stability requirements of less than 0.05 arcsecond jitter over periods of 5-20 seconds. Quantitative derivations of these requirements from two different aspects are presented: (1) avoidance of motion blurring of diffraction-limited images; (2) precise coalignment of consecutive frames to allow measurement of small image differences. To achieve this stability, a fine guider system capable of removing residual jitter of the IPS and image motions generated on the IPS cruciform instrument support structure has been constructed. This system uses solar limb detectors in the prime focal plane to derive an error signal. Image motion due to pointing errors is compensated by the agile secondary mirror mounted on piezoelectric transducers, controlled by a closed-loop servo system.

Neutrinos today

After the famous 1983 discovery of intermediate W, Z 0 bosons it may be stated with certainty that W, Z 0 are entirely responsible for the production of neutrinos and for their interactions. Neutrino physics notions are presented from this point of view in the first four introductory, quite elementary, paragraphs of the paper. The following seven paragraphs are more sophisticated. They are devoted to the neutrino mass and neutrino mixing question, which is the most actual problem in today neutrino physics. Vacuum neutrino oscillations, matter neutrino oscillations and netrinoless double-decay are considered. Solar neutrino physics is discussed in some detail from the point of view of vacuum and matter neutrino oscillations. The role played by neutrinos in the Universe is briefly considered. In the last paragraph there discussed the probable observation by different groups of neutrinos connected with the Supernova 1987 A: the first observation of gravitational star collapse (at least the general rehearsal of such observation) opens up a new era in astronomy of today exerimental physics and astrophysics is presented at the end of the paper in the form of a Table

Salivary gland ultrastructure and cyclic AMP-dependent reactions in Spacelab 3 rats

International Nuclear Information System (INIS)

Mednieks, M.I.; Hand, A.R.

1987-01-01

Environmental stimuli influencing catecholamine levels induce changes in cyclic AMP-dependent reactions and cell morphology in the rat parotid. Responses of salivary glands to spaceflight were determined by measurement of cyclic AMP-mediated reactions in fresh-frozen salivary glands and by microscopic evaluation of ultrastructure in fixed parotid glands. Decreased cell-free protein phosphorylation, determined by autoradiography, occurred in parotid glands in three of five flight animals. Protein kinase activity ratios were decreased in the soluble and increased in the particulate fractions of Spacelab 3 (SL-3) rat sublingual glands, compared with ground controls. Biochemical analyses show that effects of space flight on salivary glands are similar to those induced experimentally by physiological manipulation or alteration of catecholamine levels. Morphological evaluation of three SL-3 rat parotid glands showed increased numbers of lysosomes, autophagic vacuoles containing degenerating secretory product, and accumulation of lipid droplets. Since these animals lost weight, consistent with disruption of food and water consumption, morphological changes may in part be due to decreased masticatory stimulation, as occurs with reduced food intake or a liquid diet. The observed changes may reflect physiological responses of the gastrointestinal and autonomic systems to effects of spaceflight

Connected minds technology and today's learners

Pedrò, Francesc

2012-01-01

In all OECD countries, digital media and connectedness are integral to the lives of todays learners. It is often claimed that these learners are ""new millennium learners"", or ""digital natives"", who have different expectations about education. This book contributes to the debate about the effects of technology attachment and connectedness on todays learners, and their expectations about teaching. The book sets out to answer the following questions: Can the claim that todays students are ""new millenium learners"" or ""digital natives be sustained empirically? Is there consistent research evidence demonstrating the effects of technology on cognitive development, social values, and learning expectations? What are the implications for educational policy and practice?

The use of Light Detection and Ranging (LiDAR) remote sensing technology to scan and map landscapes has proven to be one of the most popular techniques to accurately map topography. Thus, LiDAR technology is the ultimate method of unveiling the surface feature under dense vegetation, and, this paper intends to emphasize the diverse techniques that can be utilized to elucidate topographical changes over the study area, using multi-temporal airborne full waveform LiDAR datasets collected in 2012 and 2014. Full waveform LiDAR data offers access to an almost unlimited number of returns per shot, which enables the user to explore in detail topographical changes, such as vegetation growth measurement. The study also found out topography changes at the study area due to earthwork activities contributing to soil consolidation, soil erosion and runoff, requiring cautious monitoring. The implications of this study not only concurs with numerous investigations undertaken by prominent researchers to improve decision making, but also corroborates once again that investigations employing multi-temporal LiDAR data to unveil topography changes in vegetated terrains, produce more detailed and accurate results than most other remote sensing data.

Gaseous environment of the Shuttle early in the Spacelab 2 mission

Pickett, Jolene S.; Murphy, Gerald B.; Kurth, William S.

1988-01-01

A cold-cathode ionization gage was flown on Space Shuttle flight STS-5IF as part of the Spacelab 2 payload. Neutral pressure data that were taken in the payload bay during the first few hours on orbit are presented. These data show that when the payload bay is oriented such that the atmospheric gases are ramming into it, the pressure rises to a peak of 4 x 10 to the -6th Torr. Pressure is also slightly higher during the sunlit portion of each orbit. Outgassing of the payload bay causes the pressure to be elevated to a few times 10 to the -6th Torr early in the mission. In addition, several effects on pressure have been identified that are due to chemical releases. Substantial increases (50-150 percent) are seen during another experiment's gas purge. Orbiter chemical-release effects include: pressure increases of 200 percent up to 7 x 10 to the -6th Torr due to Orbital Maneuvering System burns, minor perturbations in pressure due to vernier thruster firings and little or no increase in pressure due to water dumps. In the case of vernier thruster firings, effects are seen only from down-firing thrusters in the back of the Orbiter, which are probably due to reflection of thruster gases off Orbiter surfaces.

Papineau, N.; Camy-Peyret, C.; Ackerman, Marcel E.

1989-10-01

Measurements of atmospheric trace gases have been performed during the first Spacelab mission on board the Space Shuttle. The principle of the observations is infrared absorption spectroscopy using the solar occultation technique. Infrared absorption spectra of NO, CO, CO2, NO2, N20, CH4 and H2O have been recorded using the Grille spectrometer developped by ONERA and IASB. From the observed spectra, vertical profiles for these molecules have been derived. The present paper summarizes the main results and compares them with computed vertical profiles from a zonally averaged model of the middle atmosphere. The scientific objectives of the second mission, Atlas 1, planned for 1990 are also presented.

'THE UNVEILED HEART' a teaching program in cardiovascular nuclear medicine

International Nuclear Information System (INIS)

Itti, Roland; Merabet, Yasmina; Roca, Ramona; Bontemps, Laurence; Itti, Emmanuel

2004-01-01

The functional investigation of cardiac diseases using nuclear techniques involves several variables, such as myocardial perfusion, cellular viability or mechanical contraction. The combined, topographical and quantitative assessment of these variables can characterize the functional state of the heart in terms of normal myocardium, ischemia, hibernation or necrosis. The teaching program, 'The Unveiled Heart', has been designed in order to help nuclear physicians or cardiologists approaching these concepts and their implications for diagnosis of coronary artery disease, optimization of therapeutic strategies and prognosis evaluation. Anatomical correlations with coronary angiographic results obtained during balloon occlusion at the time of coronary angioplasty demonstrate the complementary role of imaging techniques and highlight the patient to patient variability of risk areas. A sectorial model derived from a polar projection of the myocardium presents for each sector the probability of involvement of a given coronary artery

Nuclear energy today

International Nuclear Information System (INIS)

2003-01-01

Energy is the power of the world's economies, whose appetite for this commodity is increasing as the leading economies expand and developing economies grow. How to provide the energy demanded while protecting our environment and conserving natural resources is a vital question facing us today. Many parts of our society are debating how to power the future and whether nuclear energy should play a role. Nuclear energy is a complex technology with serious issues and a controversial past. Yet it also has the potential to provide considerable benefits. In pondering the future of this imposing technology, people want to know. - How safe is nuclear energy? - Is nuclear energy economically competitive? - What role can nuclear energy play in meeting greenhouse gas reduction targets? - What can be done with the radioactive waste it generates? - Does its use increase the risk of proliferation of nuclear weapons? - Are there sufficient and secure resources to permit its prolonged exploitation? - Can tomorrow's nuclear energy be better than today's? This publication provides authoritative and factual replies to these questions. Written primarily to inform policy makers, it will also serve interested members of the public, academics, journalists and industry leaders. (author)

Use of a FORTH-based PROLOG for real-time expert systems. 1: Spacelab life sciences experiment application

Science.gov (United States)

Paloski, William H.; Odette, Louis L.; Krever, Alfred J.; West, Allison K.

1987-01-01

A real-time expert system is being developed to serve as the astronaut interface for a series of Spacelab vestibular experiments. This expert system is written in a version of Prolog that is itself written in Forth. The Prolog contains a predicate that can be used to execute Forth definitions; thus, the Forth becomes an embedded real-time operating system within the Prolog programming environment. The expert system consists of a data base containing detailed operational instructions for each experiment, a rule base containing Prolog clauses used to determine the next step in an experiment sequence, and a procedure base containing Prolog goals formed from real-time routines coded in Forth. In this paper, we demonstrate and describe the techniques and considerations used to develop this real-time expert system, and we conclude that Forth-based Prolog provides a viable implementation vehicle for this and similar applications.

Spacelab 1 hematology experiment (INS103): Influence of space flight on erythrokinetics in man

1985-01-01

An experiment conducted on the 10-day Spacelab 1 mission aboard the ninth Space Shuttle flight in November to December 1983 was designed to measure factors involved in the control of erythrocyte turnover that might be altered during weightlessness. Blood samples were collected before, during, and after the flight. Immediately after landing, red cell mass showed a mean decrease of 9.3 percent in the four astronauts. Neither hyperoxia nor an increase in blood phosphate was a cause of the decrease. Red cell survival time and iron incorporation postflight were not significantly different from their preflight levels. Serum haptoglobin did not decrease, indicating that intravascular hemolysis was not a major cause of red cell mass change. An increase in serum ferritin after the second day of flight may have been caused by red cell breakdown early in flight. Erythropoietin levels decreased during and after flight, but preflight levels were high and the decrease was not significant. The space flight-induced decrease in red cell mass may result from a failure of erythropoiesis to replace cells destroyed by the spleen soon after weightlessness is attained.

Communication network for decentralized remote tele-science during the Spacelab mission IML-2

Christ, Uwe; Schulz, Klaus-Juergen; Incollingo, Marco

1994-01-01

The ESA communication network for decentralized remote telescience during the Spacelab mission IML-2, called Interconnection Ground Subnetwork (IGS), provided data, voice conferencing, video distribution/conferencing and high rate data services to 5 remote user centers in Europe. The combination of services allowed the experimenters to interact with their experiments as they would normally do from the Payload Operations Control Center (POCC) at MSFC. In addition, to enhance their science results, they were able to make use of reference facilities and computing resources in their home laboratory, which typically are not available in the POCC. Characteristics of the IML-2 communications implementation were the adaptation to the different user needs based on modular service capabilities of IGS and the cost optimization for the connectivity. This was achieved by using a combination of traditional leased lines, satellite based VSAT connectivity and N-ISDN according to the simulation and mission schedule for each remote site. The central management system of IGS allows minimization of staffing and the involvement of communications personnel at the remote sites. The successful operation of IGS for IML-2 as a precursor network for the Columbus Orbital Facility (COF) has proven the concept for communications to support the operation of the COF decentralized scenario.

This volume (2), which consists of two parts (A and B), of the Plasma Diagnostics Package (PDP) Final Science Report contains a summary of all of the data reduction and scientific analyses which were performed using PDP data obtained on STS-51F as a part of the Spacelab 2 (SL-2) payload. This work was performed during the period of launch, July 29, l985, through June 30, l988. During this period the primary data reduction effort consisted of processing summary plots of the data received by 12 of the 14 instruments located on the PDP and submitting these data to the National Space Science Data Center (NSSDC). The scientific analyses during the performance period consisted of follow-up studies of shuttle orbiter environment and orbiter/ionosphere interactions and various plasma particle and wave studies which dealt with data taken when the PDP was on the Remote Manipulator System (RMS) arm and when the PDP was in free flight. Of particular interest during the RMS operations and free flight were the orbiter wake studies and joint studies of beam/plasma interactions with the SL-2 Fast Pulse Electron Generator (FPEG) of the Vehicle Charging and Potential Investigation (VCAP). Internal reports, published papers and presentations which involve PDP/SL-2 data are listed in Sections 3 and 4. A PDP/SL-2 scientific results meeting was held at the University of Iowa on June 10, l986. This meeting was attended by most of the PDP and VCAP investigators and provided a forum for discussing and comparing the various results, particularly with regard to the PDP free flight.

To enhance the understanding and effect of physician's difficulties, attitudes and communication styles on the disclosure of the diagnosis of AD in practice. Qualitative, phenomenological study, combining pre-encounter interviews with physicians, observations of actual encounters of diagnosis disclosure of AD, and post-encounter interviews. There were various ways or tactics to (un)veil the bad news that may be perceived as different ways of dulling the impact and avoiding full and therefore problematic statements. In the actual encounters this was accomplished by keeping encounters short, avoiding elaboration, confirmation of comprehension and explicit terminology and using fractured sentences. The present study's findings highlight the difficulties encountered in breaking the news about AD, in the way it is actually done, and the problems that may arise from this way of un/veiling the news. The main problem is that the reluctance to make a candid disclosure of the diagnosis as was demonstrated in this study may violate basic moral and legal rights and may also deprive patients and caregivers of some of the benefits of early disclosure of diagnosis. There is a need for assisting physicians to cope with their personal difficulties, problems and pitfalls in breaking the news.

The Prospects of Radical Change Today

Directory of Open Access Journals (Sweden)

Slavoj Žižek

2018-05-01

Full Text Available In this contribution, Slavoj Žižek takes the occasion of Marx’s bicentenary for reflecting on the prospects of radical change today. First, it is shown that under Stalinism, Lenin’s works were quoted out of context in an arbitrary way in order to legitimise arbitrary political measures. Marxism thereby became an ideology that justified brutal subjective interventions. Second, this contribution poses the question of the revolutionary subject and democracy today. It stresses the role of both contingency and strategy in revolutions. In political assemblages taking place on public squares, the inert mass of ordinary people is transubstantiated into a politically engaged united force. The basic political problem today is how to best reconfigure democracy. Third, this contribution analyses the “interesting times” we live in. These are times that feature multiple crises, right-wing populism à la Donald Trump and Marine Le Pen, the lower classes’ opposition to immigration, and the refugee crisis. Questions about human rights and their violation and about radical change need to be asked in this context.

After a longer starting period many radiation techniques have prevailed practically. Today radiation processes are usual components of chemistry, biology, medicine, and technologies in the most common sense. This paper deals with the latest state of radiation chemistry, whereas the possible practical applications are in the foreground of discussion as to reach mainly practicians in laboratory and industry. But also physicians, pharmacists and chemical engineers should be informed about the possibilities of application of high energyy radiation. Because radiation chemistry has also enriched works of related subjects, for example physical, organic and inorganic chemistry, this paper will also be of interest for experts of these disciplines.

The task phase concerned with the requirements, design, and planning studies for the carry-on laboratory (COL) began with a definition of biomedical research areas and candidate research equipment, and then went on to develop conceptual layouts for COL which were each evaluated in order to arrive at a final conceptual design. Each step in this design/evaluation process concerned itself with man/systems integration research and hardware, and life support and protective systems research and equipment selection. COL integration studies were also conducted and include attention to electrical power and data management requirements, operational considerations, and shuttle/Spacelab interface specifications. A COL program schedule was compiled, and a cost analysis was finalized which takes into account work breakdown, annual funding, and cost reduction guidelines.

Statistical properties of solar granulation from the SOUP instrument on Spacelab 2

Topka, K.; Title, A.; Tarbell, T.; Ferguson, S.; Shine, R.

1988-01-01

The Solar Optical Universal Polarimeter (SOUP) on Spacelab 2 collected movies of solar granulation completely free from atmospheric blurring, and are not degraded by pointint jitter (the pointing stability was 0.003 sec root mean square). The movies illustrate that the solar five minute oscillation has a major role in the appearance of solar granulation and that exploding granules are a common feature of the granule evolution. Using 3-D Fourier filtering techniques the oscillations were removed and it was demonstrated that the autocorrelation lifetime of granulation is a factor of two greater in magnetic field regions than in field-free quiet sun. Horizontal velocities were measured and flow patterns were observed on the scale of meso- and super granulation. In quiet regions the mean flow velocity is 370 m/s while in the magnetic regions it is about 125 m/s. It was also found that the root mean square (RMS) fluctuating horizonal velocity field is substantially greater in quiet sun than in strong magnetic field regions. By superimposing the location of exploding granules on the average flow maps it was found that they appear almost exclusively in the center of mesogranulation size flow cells. Because of the nonuniformity of the distribution of exploding granules, the evolution of the granulation pattern in mesogranule cell centers and boundaries differs fundamentally. It is clear from this study there is neither a typical granule nor a typical granule evolution

As the health care revolution progresses, so must the management styles of today's leaders. The authors must ask ourselves if we are managing tomorrow's work force or the work force of the past. Participatory management may better meet the needs of today's work force. This paper identifies the reasons participatory management is a more effective management style, the methods used to implement a participatory management program, its benefits (such as higher productivity and more efficient, effective implementation and acceptance of change), and the difficulties experienced

We carried out polarimetric spectral-line imaging of the molecular outflow of the peculiar red supergiant VY Canis Majoris in SiO J=1-0 line in the ground vibrational state, which contains highly linearly-polarized velocity components, using the Very Large Array. We succeeded in unveiling the highly linearly polarized bipolar outflow for the first time at subarcsecond spatial resolution. The results clearly show that the direction of linear polarization of the brightest maser components is parallel to the outflow axis. The results strongly suggest that the linear polarization of the SiO maser is closely related to the outflow phenomena of the star. Furthermore, the results indicate that the linear polarization observed in the optical and infrared also occur due to the outflow phenomena.

Unveiling protein functions through the dynamics of the interaction network.

Directory of Open Access Journals (Sweden)

Irene Sendiña-Nadal

Full Text Available Protein interaction networks have become a tool to study biological processes, either for predicting molecular functions or for designing proper new drugs to regulate the main biological interactions. Furthermore, such networks are known to be organized in sub-networks of proteins contributing to the same cellular function. However, the protein function prediction is not accurate and each protein has traditionally been assigned to only one function by the network formalism. By considering the network of the physical interactions between proteins of the yeast together with a manual and single functional classification scheme, we introduce a method able to reveal important information on protein function, at both micro- and macro-scale. In particular, the inspection of the properties of oscillatory dynamics on top of the protein interaction network leads to the identification of misclassification problems in protein function assignments, as well as to unveil correct identification of protein functions. We also demonstrate that our approach can give a network representation of the meta-organization of biological processes by unraveling the interactions between different functional classes.

Full Text Available Throughout time, the predominant use of certain languages has allowed some nations to take control over others and assure for them a privileged position. This study unveiled how certain practices and ideologies in regard to bilingualism have influenced teachers’ professional development. Data were collected through discussion group sessions, reflective journals, and protocols from five teachers from a private K-11 school in Bogota. Analysis indicated participants’ discourses drew on hegemonic, colonial, and manipulative ideas. Nevertheless, when dialoguing and peer coaching, a discourse of resistance was constituted. The study suggested further research into teachers’ professional growth, bilingualism, and bilingual education in monolingual contexts as the Colombian one.

The most important contributions of Einstein involve 5 fields of physics : the existence of quanta (light quanta, stimulated radiation emission and Bose-Einstein condensation), relativity, fluctuations (Brownian motion and thermodynamical fluctuations), the basis of quantum physics and cosmology (cosmological constant and the expansion of the universe). Diverse and renowned physicists have appreciated the development of modern physics from Einstein's ideas to the knowledge of today. This book is a collective book that gathers their work under 7 chapters: 1) 1905, a new beginning; 2) from the Einstein, Podolsky and Rosen's article to quantum information (cryptography and quantum computers); 3) the Bose-Einstein condensation in gases; 4) from stimulated emission to the today's lasers; 5) Brownian motion and the fluctuation-dissipation theory; 6) general relativity; and 7) cosmology.

The interplay between extreme events in the Amazon's precipitation and the anomaly in the temperature of the surrounding oceans is not fully understood, especially its causal relations. In this paper, we investigate the climatic interaction between these regions from 1999 until 2012 using modern tools of complex system science. We identify the time scale of the coupling quantitatively and unveil the non-stationary influence of the ocean's temperature. The findings show consistently the distinctions between the coupling in the recent major extreme events in Amazonia, such as the two droughts that happened in 2005 and 2010 and the three floods during 1999, 2009 and 2012. Interestingly, the results also reveal the influence over the anomalous precipitation of Southwest Amazon has become increasingly lagged. The analysis can shed light on the underlying dynamics of the climate network system and consequently can improve predictions of extreme rainfall events.

Challenging today's nuclear industry to be competitive in a changing tomorrow

Plug, B.

1996-01-01

As the millennium approaches, the future of the nuclear power generation appears desolate. Today's nuclear executives are facing challenges resulting from worldwide change and have forced utilities to reevaluate their corporation's future directions. The nuclear industry must be competitive more than ever to address today's rapid changing marketplace and pressures exerted from: regulatory reformation; increased competition; changes in technology; customer evolution; and globalization. These factors have compelled nuclear executives to address questions such as: What impact will these changes have on today's marketplace, and on my corporation? What will characterize tomorrow's successful nuclear facility? How can today's nuclear corporation compete in tomorrow's marketplace? Will my corporation survive? (author)

Psychoanalysis today

FONAGY, PETER

2003-01-01

The paper discusses the precarious position of psychoanalysis, a therapeutic approach which historically has defined itself by freedom from constraint and counted treatment length not in terms of number of sessions but in terms of years, in today's era of empirically validated treatments and brief structured interventions. The evidence that exists for the effectiveness of psychoanalysis as a treatment for psychological disorder is reviewed. The evidence base is significant and growing, but less than might meet criteria for an empirically based therapy. The author goes on to argue that the absence of evidence may be symptomatic of the epistemic difficulties that psychoanalysis faces in the context of 21st century psychiatry, and examines some of the philosophical problems faced by psychoanalysis as a model of the mind. Finally some changes necessary in order to ensure a future for psychoanalysis and psychoanalytic therapies within psychiatry are suggested. PMID:16946899

Today, new technologies revolutionize the way of handling information, exchanging knowledge and learning. The definition of the term ''e-learning'' mostly comprehends teaching and learning using a range of electronic media (Internet, CD-ROMs). However, further differentiation is necessary to describe the entire spectrum of methods included in this term. These different approaches are reflected in their implementation by the companies presented. (orig.)

Mechanical vapor compression refrigeration for low temperature industrial applications today

International Nuclear Information System (INIS)

Ferguson, J.E.

1987-01-01

If the super conductor industry settles out at a temperature of -100 0 F or above, mechanical refrigeration will be vying for the cooling business. Today there very definitely is a break point in the application of equipment at approximately -120 0 F or 189 0 K. Other technologies are generally utilized below this level. However, with market potential comes invention and breakthroughs in refrigeration can also occur. Today standard refrigeration systems are cost effective, reliable and produced in the millions for high temperature applications of +10 0 F to +40 0 F evaporator temperature. Lower temperatures require additional hardware, consume additional power and are produced today in limited quantities for special applications

Anon.

1988-01-01

The worldwide market for superconductive products may exceed $1 billion in 1987. These products are expanding the frontiers of science, revolutionizing the art of medical diagnosis, and developing the energy technology of the future. In general, today's customers for superconductive equipment want the highest possible performance, almost regardless of cost. The products operate within a few degrees of absolute zero, and virtually all are fabricated from niobium or niobium alloys-so far the high-temperature superconductors discovered in 1986 and 1987 have had no impact on these markets. The industry shows potential and profound societal impact, even without the new materials

For Earth into space: The German Spacelab Mission D-2

Science.gov (United States)

Sahm, P. R.; Keller, M. H.; Schiewe, B.

The Spacelab Mission D-2 successfully lifted off from Kennedy Space Center on April 26, 1993. With 88 experiments on board covering eleven different research disciplines it was a very ambitious mission. Besides materials and life science subjects, the mission also encompassed astronomy, earth observation, radiation physics and biology, telecommunication, automation and robotics. Notable results were obtained in almost all cases. To give some examples of the scientific output, building upon results obtained in previous missions (FSLP, D1) diffusion in melts was broadly represented delivering most precise data on the atomic mobility within various liquids, and crystal growth experiments (the largest gallium arsenide crystal grown by the floating zone technique, so far obtained anywhere, was one of the results), biological cell growth experiments were continued (for example, beer yeast cultures, continuing their growth on earth, delivered a qualitatively superior brewery result), the human physiology miniclinic configuration ANTHRORACK gave novel insights concerning cardiovascular, pulmonary, and renal (fluid volume determining) factors. Astronomical experiments yielded insights into our own galaxy within the ultra violet spectrum, earth observation experiments delivered the most precise resolution data superimposed by thematic mapping of many areas of the Earth, and the robotics experiment brought a remarkable feature in that a flying object was caught by the space robot, which was only achieved through several innovative advances during the time of experiment preparation. The eight years of preparation were also beneficial in another sense. Several discoveries have been made, and various technology transfers into ground-based processes were verified. To name the outstanding ones, in the materials science a novel bearing materials production process was developped, a patent granted for an improved high temperature heating chamber; with life sciences a new hormone

Corrosion issues in nuclear industry today

International Nuclear Information System (INIS)

Cattant, F.; Crusset, D.; Feron, D.

2008-01-01

In the context of global warming, nuclear energy is a carbon-free source of power and so is a meaningful option for energy production without CO 2 emissions. Currently, there are more than 440 commercial nuclear reactors, accounting for about 15% of electric power generation in the world, and there has not been a major accident in over 20 years. The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate for longer than this. The re-emergence of nuclear power today is founded on the present generation of nuclear reactors meeting the demands of extended service life, ensuring the cost competitiveness of nuclear power and matching enhanced safety requirements. Nuclear power plant engineers should be able to demonstrate such integrity and reliability of their system materials and components as to enable nuclear power plants to operate beyond their initial design life. Effective waste management is another challenge for sustainable nuclear energy today; more precisely, a solution is needed for the management of high-level and long-lived intermediate-level radioactive waste over the very long term. Most nuclear countries are currently gathering the data needed to assess the feasibility of a deep geological waste repository, including the prediction of the behaviour of materials over several thousands of years. The extended service life of nuclear power plants and the need for permanent disposal for nuclear waste are today's key issues in the nuclear industry. We focus here on the major role that corrosion plays in these two factors, and on the French approaches to these two issues. (authors)

Energy supply today and tomorrow, national and global

International Nuclear Information System (INIS)

Ott, G.

2003-01-01

A status report about 'Energy Supply Today and Tomorrow, National and Global' focuses mainly on global aspects. Today's world energy consumption is dominated by more than 80% of fossil sources of energy followed by so-called non-commercial energies, such as wood and plant and animal wastes, contributing 10%; nuclear power, 7%; and hydroelectric power, 2%. The development of energy consumption until the middle of this century will continue to be driven by the further growth of the world population, and by the need to meet the rising demand for energy in the developing countries. Because of their availability and flexible uses, oil, natural gas, and coal as fossil sources of energy will continue to meet a considerable share of the requirement. The use of nuclear power, a source meeting all criteria, such as safety, waste management, and competitiveness, is both justifiable and desirable. Restrictive decisions about nuclear power taken today must not impair the freedom of choice of future generations. Using renewable energies is just as desirable as increasing energy efficiency; however, the technical and physical potentials available for this purpose should not be overrated. This makes it imperative to protect the supply of energy 'in this difficult interim phase' with all the options available, and to open up prospects for the future, also by conducting the appropriate energy and environmental research. The balance between continuity of supply, environmental compatibility, and competitiveness must be taken into account in this effort. In the second half of the 21 st century, it is possible that energy consumption will stabilize when the world's population ceases to grow. New technologies, some of which may not even be known today or may still be under development, could then pave the way for an energy supply system which, in toto, would be less of a burden on the environment.

POLAR is a novel compact space-borne Compton polarimeter conceived for a precise measurement of hard X-ray/Gamma-ray polarization and optimized for the detection of the prompt emission of Gamma-Ray Bursts (GRB) in the energy range 50 - 500 keV. The future detailed measurement of the polarization of GRB will lead to a better understanding of its radiation region geometry and emission mechanisms. Thanks to its remarkable properties on large effective area, field of view (4.14 sr or 1/3 of the visible sky) and obvious modulation factor, POLAR will be able to reach a minimum detectable polarization (1-σ level) of about 3% for several GRB measurements per year. POLAR consists of 25 detector modular units (DMU). Each DMU is composed of 64 low-Z plastic scintillator bars, read out by a flat-panel multi-anode photomultipliers and ASIC front-end electronics. The incoming photons undergo Compton scattering in the bars and produce a modulation pattern. Simulations and hard X-ray synchrotron radiation experiments have shown that the polarization degree and angle can be retrieved from this pattern with the accuracy necessary for pinning down the GRB mechanisms. A full flight model of POLAR has been constructed, in view of a flight on the Chinese spacelab TG-2 expected in 2016. The design of POLAR, Monte-Carlo simulation analysis as well as the performance test results will be all addressed in details in this talk.

Gilson, Krapiec and Christian Philosophy Today

Directory of Open Access Journals (Sweden)

Pawel Tarasiewicz

2015-12-01

Full Text Available The author undertakes an attempt to answer the following question: is Christian philosophy possible today? The question seems to be of great importance due to the fact that what Christians who try to do philosophy usually encounter is bitter criticism which comes to them from two sides at once: that of academy and that of the Church. In short, for academy their philosophy is too Christian, and for the Church it is too academic. Being indebted to the insights of Étienne Gilson and Mieczyslaw A. Krapiec (the original Polish spelling: Mieczysław Albert Krąpiec, pronounced: myechisuaf albert krompyetz, the author comes to the conclusion thatChristian philosophy is possible today only if: 1 it isnot identified with the art of persuasion, as its final end lies in gaining understanding rather than being convincing, 2 itis the work of a Christian, and 3 it has thereal world as its object and metaphysics as its method. ForChristian philosophy—which in essence consists indoing philosophy by Christians in order to get morerational understanding of their religious faith—shouldbe identified with theperfection of the intellect achieved by practicingthe classical philosophy of being.

The ASME Code today -- Challenges, threats, opportunities

International Nuclear Information System (INIS)

Canonico, D.A.

1995-01-01

Since its modest beginning as a single volume in 1914 the ASME Code, or some of its parts, is recognized today in 48 of the United States and all providence's of Canada. The ASME Code today is composed of 25 books including two Code Case books. These books cover the new construction of boilers and pressure vessels and the new construction and In-Service-Inspection of Nuclear Power Plant components. The ASME accredits all manufacturers of boilers and pressure vessels built to the ASME Code. There are approximately 7650 symbol stamps issued throughout the world. Over 23% of the symbol stamps have been issued outside the USA and Canada. The challenge to the ASME Code is to be accepted as the world standard for pressure boundary components. There are activities underway to achieve that goal. The ASME Code is being revised to make it a more friendly document to entities outside of North America. To achieve that end there are specific tasks underway which are described here

Hidden temporal order unveiled in stock market volatility variance

Directory of Open Access Journals (Sweden)

Y. Shapira

2011-06-01

Full Text Available When analyzed by standard statistical methods, the time series of the daily return of financial indices appear to behave as Markov random series with no apparent temporal order or memory. This empirical result seems to be counter intuitive since investor are influenced by both short and long term past market behaviors. Consequently much effort has been devoted to unveil hidden temporal order in the market dynamics. Here we show that temporal order is hidden in the series of the variance of the stocks volatility. First we show that the correlation between the variances of the daily returns and means of segments of these time series is very large and thus cannot be the output of random series, unless it has some temporal order in it. Next we show that while the temporal order does not show in the series of the daily return, rather in the variation of the corresponding volatility series. More specifically, we found that the behavior of the shuffled time series is equivalent to that of a random time series, while that of the original time series have large deviations from the expected random behavior, which is the result of temporal structure. We found the same generic behavior in 10 different stock markets from 7 different countries. We also present analysis of specially constructed sequences in order to better understand the origin of the observed temporal order in the market sequences. Each sequence was constructed from segments with equal number of elements taken from algebraic distributions of three different slopes.

Called to respond: The potential of unveiling hiddens

Directory of Open Access Journals (Sweden)

Alison L Black

2014-12-01

Full Text Available Interested in exploring how personal stories and aesthetic modes of representing experiences can nudge open academic and educational spaces, this article/collection of particles seeks to document our encounters of being affected and called to respond to things the other has written and represented. As a way of engaging with questions about what research and research data might be and become, our attention has been drawn to stories and images from our lives that we have not shaken off – and to how, as we have opened these to the other, making once private moments public, our hiddens have morphed tenderly into a shared knowing and being. As we have acted on the call we have felt to respond we have found ourselves entering spaces of collaboration, communion, contemplation, and conversation – spaces illuminated by what we have not been able to – and cannot – set aside. Using visual and poetic materials we explore heartfelt and heartbroken aspects of our educational worlds and lives, to be present with each other and our (reemerging personal and professional meanings. We see the shared body (of work, of writing, of image that develops from the taking of brave steps and the risky slipping off of academic masks and language, as a manifestation of the trusted and nurturing spaces that can be generated through collaborative opportunities to gather together. These steps towards unveiling hiddens are producing in us and of us a friendship, fluency, and fluidity as we write new ways of becoming. In turn, we hope the uncovering and revealing of our dialogue in the public gathering of this journal might supports readers’ telling of their own life stories through what calls them to respond.

Unveiling the biotransformation mechanism of indole in a Cupriavidus sp. strain.

Indole, an important signaling molecule as well as a typical N-heterocyclic aromatic pollutant, is widespread in nature. However, the biotransformation mechanisms of indole are still poorly studied. Here, we sought to unlock the genetic determinants of indole biotransformation in strain Cupriavidus sp. SHE based on genomics, proteomics and functional studies. A total of 177 proteins were notably altered (118 up- and 59 downregulated) in cells grown in indole mineral salt medium when compared with that in sodium citrate medium. RT-qPCR and gene knockout assays demonstrated that an indole oxygenase gene cluster was responsible for the indole upstream metabolism. A functional indole oxygenase, termed IndA, was identified in the cluster, and its catalytic efficiency was higher than those of previously reported indole oxidation enzymes. Furthermore, the indole downstream metabolism was found to proceed via the atypical CoA-thioester pathway rather than conventional gentisate and salicylate pathways. This unusual pathway was catalyzed by a conserved 2-aminobenzoyl-CoA gene cluster, among which the 2-aminobenzoyl-CoA ligase initiated anthranilate transformation. This study unveils the genetic determinants of indole biotransformation and will provide new insights into our understanding of indole biodegradation in natural environments and its functional studies. © 2017 John Wiley & Sons Ltd.

Alternative motor fuels today and tomorrow

International Nuclear Information System (INIS)

Bensaid, B.

2004-01-01

Today, petroleum products account for 97% of the energy consumed in road transport. The purpose of replacing these products with alternative energies is to reduce oil dependence as well as greenhouse gas emissions. The high price of oil has promoted the use of 'conventional' alternative motor fuels (biofuels, LPG, NGV) and also renewed interest in syn-fuels (GTL, CTL, BTL) that have already given rise to industrial and pilot projects.

Understanding the mechanism of catalytic fast pyrolysis by unveiling reactive intermediates in heterogeneous catalysis

Science.gov (United States)

Hemberger, Patrick; Custodis, Victoria B. F.; Bodi, Andras; Gerber, Thomas; van Bokhoven, Jeroen A.

2017-06-01

Catalytic fast pyrolysis is a promising way to convert lignin into fine chemicals and fuels, but current approaches lack selectivity and yield unsatisfactory conversion. Understanding the pyrolysis reaction mechanism at the molecular level may help to make this sustainable process more economic. Reactive intermediates are responsible for product branching and hold the key to unveiling these mechanisms, but are notoriously difficult to detect isomer-selectively. Here, we investigate the catalytic pyrolysis of guaiacol, a lignin model compound, using photoelectron photoion coincidence spectroscopy with synchrotron radiation, which allows for isomer-selective detection of reactive intermediates. In combination with ambient pressure pyrolysis, we identify fulvenone as the central reactive intermediate, generated by catalytic demethylation to catechol and subsequent dehydration. The fulvenone ketene is responsible for the phenol formation. This technique may open unique opportunities for isomer-resolved probing in catalysis, and holds the potential for achieving a mechanistic understanding of complex, real-life catalytic processes.

Traditional Islamic cities unveiled: the quest for urban design regularity

Directory of Open Access Journals (Sweden)

Jorge Correia

2015-08-01

Full Text Available Traditional Islamic cities have generally gathered orientalized gazes and perspectives, picking up from misconceptions and stereotypes that during the second half af the 19th century andwere perpectuated by colonialism. More recent scholarship has shed light on the urban organizationand composition of such tissues; most of them confined to old quarters or historical centres ofthriving contemporary cities within the Arab-Muslim world. In fact, one of the most striking featureshas been the unveiling of layered urban assemblages where exterior agents have somehowlaunched or interrupted an apparent islamicized continuum. Primarly, this paper wishes to search forexternal political factors that have designed regularly geometrized patterns in medium-sized Arabtowns. For that, two case studies from different geographies - Maghreb and the Near East - will bemorphologically analysed through updated urban surveys. Whereas Nablus (Palestine ows the urbanmatrix of its old town to its Roman past, in Azemmour’s medina (Morocco it is still possible to trackthe thin European early-modern colonial stratum. However, both cases show how regularity patternschallenge Western concepts of geometrical design to embrace levels of rationality related to tradionalIslamic urban forms, societal configurations and built environment. Urban morphology becomes afundamental tool for articulating the history with me processes of sedimentation and evolution in orderto read current urban prints and dynamics. Thus, the paper will also interpret alternative logics ofrational urban display in Azemmour and Nablus, linked to ways of living within the Islamic sphere.

Tempo and mode of genomic mutations unveil human evolutionary history.

Science.gov (United States)

Hara, Yuichiro

2015-01-01

Mutations that have occurred in human genomes provide insight into various aspects of evolutionary history such as speciation events and degrees of natural selection. Comparing genome sequences between human and great apes or among humans is a feasible approach for inferring human evolutionary history. Recent advances in high-throughput or so-called 'next-generation' DNA sequencing technologies have enabled the sequencing of thousands of individual human genomes, as well as a variety of reference genomes of hominids, many of which are publicly available. These sequence data can help to unveil the detailed demographic history of the lineage leading to humans as well as the explosion of modern human population size in the last several thousand years. In addition, high-throughput sequencing illustrates the tempo and mode of de novo mutations, which are producing human genetic variation at this moment. Pedigree-based human genome sequencing has shown that mutation rates vary significantly across the human genome. These studies have also provided an improved timescale of human evolution, because the mutation rate estimated from pedigree analysis is half that estimated from traditional analyses based on molecular phylogeny. Because of the dramatic reduction in sequencing cost, sequencing on-demand samples designed for specific studies is now also becoming popular. To produce data of sufficient quality to meet the requirements of the study, it is necessary to set an explicit sequencing plan that includes the choice of sample collection methods, sequencing platforms, and number of sequence reads.

2017-01-01

Vaccination is a complex ecosystem with several components that interact with one another and with the environment. Today's vaccine ecosystem is defined by the pursuit of polio eradication, the drive to get as many of the new vaccines to as many people as possible and the research and development against immunologically challenging diseases. Despite these successes, vaccine ecosystem is facing keys issues with regard to supply/distribution and cost/profitability asymmetry that risk slowing its global growth. The conference "Vaccination ecosystem health check: achieving impact today and sustainability for tomorrow" held in Annecy-France (January 19-21, 2015) took stock of the health of today's vaccination ecosystem and its ability to reliably and sustainably supply high-quality vaccines while investing in tomorrow's needed innovation. Small and decreasing numbers of suppliers/manufacturing facilities; paucity of research-driven companies; regulatory pressures; market uncertainties; political prioritization; anti-vaccine movements/complacency; and technological and programmatic issues were acknowledged as the major challenges that could weaken today's vaccination ecosystem. The expert panel discussed also drivers and barriers to a sustainable vaccination ecosystem; the metrics of a vaccination ecosystem; and what should be added, removed, increased, or reduced to maintain the health of the vaccination ecosystem.

Energy financing in today's world - a banker's viewpoint

International Nuclear Information System (INIS)

Mackrell, Ian

1991-01-01

If the world runs on energy, the energy industry runs on finance. Supplying the industry's huge appetite for funds -on the scale and in the form required - has always posed a major challenge to the international banking community. But in some respects that challenge is greater today than it has ever been, not only because of the industry's escalating requirements but also because of the way bank's attitudes have been changing in the recent past. One reason for this is the rapidly evolving scene within the energy business in response to the harsher competitive conditions and the greater uncertainties of tomorrow. However, the other major factor is that banking itself has been undergoing significant change as a result of severe pressures and constraints, both internal and external. Some of the key global trends and issues affecting energy financing in today's world are considered here. (author)

Understanding the early stages of star formation is a research field of ongoing development, both theoretically and observationally. In this context, molecular data have been continuously providing observational constraints on the gas dynamics at different excitation conditions and depths in the sources. We have investigated the Barnard 59 core, the only active site of star formation in the Pipe Nebula, to achieve a comprehensive view of the kinematic properties of the source. This information was derived by simultaneously fitting ammonia inversion transition lines (1, 1) and (2, 2). Our analysis unveils the imprint of protostellar feedback, such as increasing line widths, temperature, and turbulent motions in our molecular data. Combined with complementary observations of dust thermal emission, we estimate that the core is gravitationally bound following a virial analysis. If the core is not contracting, another source of internal pressure, most likely the magnetic field, is supporting it against gravitational collapse and limits its star formation efficiency.

Cellular therapies for heart disease: unveiling the ethical and public policy challenges.

Raval, Amish N; Kamp, Timothy J; Hogle, Linda F

2008-10-01

Cellular therapies have emerged as a potential revolutionary treatment for cardiovascular disease. Promising preclinical results have resulted in a flurry of basic research activity and spawned multiple clinical trials worldwide. However, the optimal cell type and delivery mode have not been determined for target patient populations. Nor have the mechanisms of benefit for the range of cellular interventions been clearly defined. Experiences to date have unveiled a myriad of ethical and public policy challenges which will affect the way researchers and clinicians make decisions for both basic and clinical research. Stem cells derived from embryos are at the forefront of the ethical and political debate, raising issues of which derivation methods are morally and socially permissible to pursue, as much as which are technically feasible. Adult stem cells are less controversial; however, important challenges exist in determining study design, cell processing, delivery mode, and target patient population. Pathways to successful commercialization and hence broad accessibility of cellular therapies for heart disease are only beginning to be explored. Comprehensive, multi-disciplinary and collaborative networks involving basic researchers, clinicians, regulatory officials and policymakers are required to share information, develop research, regulatory and policy standards and enable rational and ethical cell-based treatment approaches.

Codon-triplet context unveils unique features of the Candida albicans protein coding genome

Directory of Open Access Journals (Sweden)

Oliveira José L

2007-11-01

Full Text Available Abstract Background The evolutionary forces that determine the arrangement of synonymous codons within open reading frames and fine tune mRNA translation efficiency are not yet understood. In order to tackle this question we have carried out a large scale study of codon-triplet contexts in 11 fungal species to unravel associations or relationships between codons present at the ribosome A-, P- and E-sites during each decoding cycle. Results Our analysis unveiled high bias within the context of codon-triplets, in particular strong preference for triplets of identical codons. We have also identified a surprisingly large number of codon-triplet combinations that vanished from fungal ORFeomes. Candida albicans exacerbated these features, showed an unbalanced tRNA population for decoding its pool of codons and used near-cognate decoding for a large set of codons, suggesting that unique evolutionary forces shaped the evolution of its ORFeome. Conclusion We have developed bioinformatics tools for large-scale analysis of codon-triplet contexts. These algorithms identified codon-triplets context biases, allowed for large scale comparative codon-triplet analysis, and identified rules governing codon-triplet context. They could also detect alterations to the standard genetic code.

Knee arthrography today

International Nuclear Information System (INIS)

Otto, H.; Kallenberger, R.

1987-01-01

The role of knee arthrography today is demonstrated and technical problems are discussed. Among a lot of variants the position of the patient and the choice of contrast media play a great part concerning the result of the examination. Mild complications occur in 0.25% of the examinations, severe and live threatening complications are extremely rare. Diagnosis of meniscal lesions is most important for knee arthrography; arthroscopy and arthrography are complementary examinations and not mutually exclusive, they achieve combined an accuracy of 97-98%. In the same way arthrography is able to evaluate the condropathy of the femoro-tibial joint, whereas accuracy of arthroscopy in the diagnosis of patellar chondropathy is much higher. There is a great reliability of arthrography regarding the evaluation of lesions of the capsule, but accuracy in lesions of the cruciate ligaments is low. Arthrography is very suitable for evaluation of Baker-cysts, since indications for almost occuring internal derangement of the knee are even available. Knee arthrography is a complex and safe procedure with very less discomfort for the patient; it has a central position in the evaluation of lesions of the knee. (orig.) [de

Global aromatics supply. Today and tomorrow

Energy Technology Data Exchange (ETDEWEB)

Bender, M. [BASF SE, Ludwigshafen (Germany)

2013-11-01

Aromatics are the essential building blocks for some of the largest petrochemical products in today's use. To the vast majority they are consumed to produce intermediates for polymer products and, hence, contribute to our modern lifestyle. Their growth rates are expected to be in line with GDP growth in future. This contrasts the significantly lower growth rates of the primary sources for aromatics - fuel processing and steam cracking of naphtha fractions. A supply gap can be expected to open up in future for which creative solutions will be required. (orig.)

On 18 June CERN unveiled an unusual new landmark - a statue of the Indian deity Shiva. The statue is a gift from CERN's Indian collaborators to celebrate CERN's long association with India, which began in the 1960s. The statue was made in India in the traditional style. The original sculpture was a wax model, around which a soil mould was made. Melting the wax left a hollow into which liquid metal was poured, and once cooled the mould was split and the statue polished and given its antique finish.

Maintaining professionalism in today's business environment: ethical challenges for the pain medicine specialist.

Science.gov (United States)

Lebovits, Allen

2012-09-01

There are many external influences in today's market force that impair the relationship between the pain medicine specialist and the patient, and ultimately prevent optimal quality of care. This article explores the ethical challenges facing the pain medicine specialist in today's increasingly "business" environment and will offer solutions for maintaining the professionalism of pain medicine. Four commonly encountered bioethical principles in the practice of pain medicine are reviewed: beneficence, nonmaleficence, justice, and autonomy. The following ethical challenges of the pain medicine specialist are reviewed: practicing outside ones specialty area, practice characteristics, the consultant role, the economic lure of aggressive intervention, not evaluating for and treating comorbid psychopathology, reimbursement pressures, workers' compensation, and use of unproven methods. Solutions offered include collegial associations, social responsibility, legislative initiatives, pain education, interdisciplinary evaluation and treatment, improved relationships with third-party payers, reduced racial disparities, and ethics education. Ethics is the "roadmap" that enables the pain medicine specialist to navigate the increasingly murky waters of practicing pain management today by maintaining the professionalism necessary to combat today's "business" pressures.

2006-01-01

The primary objective of the Gemini Program was to develop techniques that would allow for advanced, long-duration space travel, a prerequisite of the ensuing Apollo Program that would put man safely on the Moon before the end of the decade. In order to carry out this objective, NASA worked with a variety of innovative companies to develop propulsion systems, onboard computers, and docking capabilities that were critical to the health of Gemini spacecraft, as well as life-support systems and physiological-monitoring devices that were critical to the health of Gemini astronauts. One of these companies was Spacelabs Medical, Inc., the pioneer of what is commonly known today as medical telemetry. Spacelabs Medical helped NASA better understand man s reaction to space through a series of bioinstrumentation devices that, for the first time ever, were capable of monitoring orbiting astronauts physical conditions in real time, from Earth. The company went on to further expand its knowledge of monitoring and maintaining health in space, and then brought it down to Earth, to dramatically change the course of patient monitoring in the field of health care.

Full Text Available Years ago, exploration was done through surface observations and „divining rods“ – now, it is done by satellites, microprocessors, remote sensing, and supercomputers. In the 1970´ s, the exploration success rate was 14 percent, today, it is nearly 29 percent. Not so long ago, three – dimension (3D seismic diagnostic techniques helped recover 25-50 percent of the oil in place – now, 4D seismic helps recover up to 70 percent of the oil in place. 3D and 4D seismic and earth imaging systems also help in understanding the subsurface flow of other fluids, such as groundwater and pollutants.Seismic surveys – a technique in which sound waves are bounced off underground rock struktures to reveal possible oil and gas bearing formation – are now standard fare for the modern petroleum industry. But today’s seismic methods are best at locating „structural traps“ where faults or folds in the underground rock have created zones where oil can become trapped.

Surprisal analysis of Glioblastoma Multiform (GBM) microRNA dynamics unveils tumor specific phenotype.

Science.gov (United States)

Zadran, Sohila; Remacle, Francoise; Levine, Raphael

2014-01-01

Gliomablastoma multiform (GBM) is the most fatal form of all brain cancers in humans. Currently there are limited diagnostic tools for GBM detection. Here, we applied surprisal analysis, a theory grounded in thermodynamics, to unveil how biomolecule energetics, specifically a redistribution of free energy amongst microRNAs (miRNAs), results in a system deviating from a non-cancer state to the GBM cancer -specific phenotypic state. Utilizing global miRNA microarray expression data of normal and GBM patients tumors, surprisal analysis characterizes a miRNA system response capable of distinguishing GBM samples from normal tissue biopsy samples. We indicate that the miRNAs contributing to this system behavior is a disease phenotypic state specific to GBM and is therefore a unique GBM-specific thermodynamic signature. MiRNAs implicated in the regulation of stochastic signaling processes crucial in the hallmarks of human cancer, dominate this GBM-cancer phenotypic state. With this theory, we were able to distinguish with high fidelity GBM patients solely by monitoring the dynamics of miRNAs present in patients' biopsy samples. We anticipate that the GBM-specific thermodynamic signature will provide a critical translational tool in better characterizing cancer types and in the development of future therapeutics for GBM.

Today's threat and tomorrow's reaction

International Nuclear Information System (INIS)

Moore, L.R.

2002-01-01

Full text: The events of September 11 have only confirmed our past nightmares and warnings to industries, agencies, and governments. The threat of even more significant catastrophic attacks, using nuclear materials, was just as real ten years ago, as it is today. In many cases, our vulnerability remains the same as years ago. There is a dire need for all organizations to agree upon threats and vulnerabilities, and to implement appropriate protections, for nuclear materials or other 'means' to achieve an event of mass destruction. All appropriate organizations (industries, agencies, and governments) should be able to define, assess, and recognize international threats and vulnerabilities in the same manner. In complimentary fashion, the organizations should be able to implement safeguards against this consistent generic threat. On an international scale the same threats, and most vulnerabilities, pose high risks to all of these organizations and societies. Indeed, in today's world, the vulnerabilities of one nation may clearly pose great risk to another nation. Once threats and vulnerabilities are consistently recognized, we can begin to approach their mitigation in a more 'universal' fashion by the application of internationally recognized and accepted security measures. The path to recognition of these security measures will require agreement on many diverse issues. However, once there is general agreement, we can then proceed to the acquisition of diverse national and international resources with which to implement the security measures 'universally' to eliminate 'weak-links' in the chain of nuclear materials, on a truly international scale. I would like to discuss: developing a internationally acceptable 'generic' statement of threat, vulnerability assessment process, and security measure; proposing this international statement of threat, vulnerability assessment process, and appropriate security measures to organizations (industries, agencies, and governments

Full Text Available The starting point of the text is a returning to the patriarchal, which is not simply the one that we are witnessing today, in the time of so-called postmodern, postpatriarchal society in its (until now last form. It is a matter of returning to rules, of which the basic premise is that adults are subjects (transcendences, freedoms, activities and children are subjects that are objects for adults (imanences, non-freedoms, pasivities, but which notwithstanding differ from the oldfashioned rules from the past. We attempted to explain this returning, following the example of rules offered by the book Children Are From Heaven – a selfhelp book, published at the end of the nineties of the 20th century, which immediately became the world's bestseller. In addition, our aim was to answer the following questions: What has happened with rules of civilization and good manners, regulating the relations between children and adults today? How have they changed and what has happened with children's or adults's relation to these rules or their performings? How has this relation changed? Considering the mentioned basic premise which implies that children respect adults, we also tried to answer the question: What has happened with the respect, or, how do children respect adults today? Disscussion is presented in the framework of lacanian psychoanalysis.

This paper reports the results of the spectroscopic analysis of C2H6 and C2H2 absorption spectra obtained by the Atmospheric Trace Molecule Spectroscopy (ATMOS) instrument flown on the Shuttle as part of the Spacelab 3 mission. The spectra were recorded during sunset occultations occurring between 25 deg N and 31 deg N latitudes, yielding volume-mixing ratio profiles of C2H6 in the lower stratosphere and the upper troposphere, and an upper tropospheric profile of C2H2. These results compare well with previous in situ and remote sounding data obtained at similar latitudes and with model calculations. The results demonstrate the feasibility of the ATMOS instrument to sound the lower atmosphere from space.

A strategy to unveil transient sources of ultra-high-energy cosmic rays

Directory of Open Access Journals (Sweden)

Takami Hajime

2013-06-01

Full Text Available Transient generation of ultra-high-energy cosmic rays (UHECRs has been motivated from promising candidates of UHECR sources such as gamma-ray bursts, flares of active galactic nuclei, and newly born neutron stars and magnetars. Here we propose a strategy to unveil transient sources of UHECRs from UHECR experiments. We demonstrate that the rate of UHECR bursts and/or flares is related to the apparent number density of UHECR sources, which is the number density estimated on the assumption of steady sources, and the time-profile spread of the bursts produced by cosmic magnetic fields. The apparent number density strongly depends on UHECR energies under a given rate of the bursts, which becomes observational evidence of transient sources. It is saturated at the number density of host galaxies of UHECR sources. We also derive constraints on the UHECR burst rate and/or energy budget of UHECRs per source as a function of the apparent source number density by using models of cosmic magnetic fields. In order to obtain a precise constraint of the UHECR burst rate, high event statistics above ∼ 1020 eV for evaluating the apparent source number density at the highest energies and better knowledge on cosmic magnetic fields by future observations and/or simulations to better estimate the time-profile spread of UHECR bursts are required. The estimated rate allows us to constrain transient UHECR sources by being compared with the occurrence rates of known energetic transient phenomena.

Enhancer Analysis Unveils Genetic Interactions between TLX and SOX2 in Neural Stem Cells and In Vivo Reprogramming.

Science.gov (United States)

Islam, Mohammed M; Smith, Derek K; Niu, Wenze; Fang, Sanhua; Iqbal, Nida; Sun, Guoqiang; Shi, Yanhong; Zhang, Chun-Li

2015-11-10

The orphan nuclear receptor TLX is a master regulator of postnatal neural stem cell (NSC) self-renewal and neurogenesis; however, it remains unclear how TLX expression is precisely regulated in these tissue-specific stem cells. Here, we show that a highly conserved cis-element within the Tlx locus functions to drive gene expression in NSCs. We demonstrate that the transcription factors SOX2 and MYT1 specifically interact with this genomic element to directly regulate Tlx enhancer activity in vivo. Knockdown experiments further reveal that SOX2 dominantly controls endogenous expression of TLX, whereas MYT1 only plays a modulatory role. Importantly, TLX is essential for SOX2-mediated in vivo reprogramming of astrocytes and itself is also sufficient to induce neurogenesis in the adult striatum. Together, these findings unveil functional genetic interactions among transcription factors that are critical to NSCs and in vivo cell reprogramming.

Unveiling the water-associated conformational mobility in the active site of ascorbate peroxidase.

Chao, Wei-Chih; Lin, Li-Ju; Lu, Jyh-Feng; Wang, Jinn-Shyan; Lin, Tzu-Chieh; Chen, Yi-Han; Chen, Yi-Ting; Yang, Hsiao-Ching; Chou, Pi-Tai

2018-03-01

We carried out comprehensive spectroscopic studies of wild type and mutants of ascorbate peroxidase (APX) to gain understanding of the conformational mobility of the active site. In this approach, three unnatural tryptophans were applied to replace the distal tryptophan (W41) in an aim to probe polarity/water environment near the edge of the heme-containing active site. 7-azatryptophan ((7-aza)Trp) is sensitive to environment polarity, while 2,7-azatryptophan ((2,7-aza)Trp) and 2,6-diazatryptophan ((2,6-aza)Trp) undergo excited-state water-catalyzed double and triple proton transfer, respectively, and are sensitive to the water network. The combination of their absorption, emission bands and the associated relaxation dynamics of these fluorescence probes, together with the Soret-band difference absorption and resonance Raman spectroscopy, lead us to unveil the water associated conformational mobility in the active site of APX. The results are suggestive of the existence of equilibrium between two different environments surrounding W41 in APX, i.e., the water-rich and water-scant forms with distinct fluorescence relaxation. Our results thus demonstrate for the first time the power of integrating multiple sensors (7-aza)Trp, (2,7-aza)Trp and (2,6-aza)Trp in probing the water environment of a specifically targeted Trp in proteins.

Wukong Sharpens Its Eyes and Unveils the Nature of Dark Matter

Science.gov (United States)

Cong, Kun-Lin

2016-07-01

Dark matter does not emit light or reflect electromagnetic radiation, but its existence can be inferred from the effects of measurements such as gravity and mass. Unveiling the nature of dark matter is one of the biggest mysteries of modern science. Exploration of dark matter could give scientists a clearer understanding of the past and future of galaxies and the universe. Chinese scientists have been engaged actively in dark matter research in recent years, and made some significant achievements in theoretical studies, numerical simulations, and experimental investigation. The Dark Matter Particles Explorer Satellite (DAMPE) was launched by LM launch vehicle on 17th December 2015. It was constructed as a scientific satellite that has four major parts - a plastic scintillator array detector, a silicon array detector, a BGO calorimeter and a neutron detector - together comprising about 76,000 minor detectors. The main scientific purpose of DAMPE is to investigate dark matter particle from deep space, via high resolution observation of gamma-rays and electrons spectra, and its space distribution. It will also help scientists study the transportation and acceleration of cosmic rays in the galaxy by measuring the energy spectra of heavy ions. DAMPE was dubbed Wukong after the Monkey King character from the Chinese classic legend Journey to the West. "Wu" means becoming aware of through the senses, and "Kong" refers to the space. The figurative meaning of "Wukong" is to know and comprehend the nature of the space. DAMPE is the most sensitive and accurate detectors designed for dark matter with the highest performance among the similar explorers.

Directory of Open Access Journals (Sweden)

Víctor Manuel Isidro Luna

2013-11-01

Full Text Available The purpose of this paper is to provide elements to reflect on the way poverty is nowadays conceptualized and on its causing factors. This paper discusses that a classic-neoclassical frame of reference cannot explain the persistence or increase of poverty in today's developed countries. This article suggests that through a Marxist historic-descriptive and theoretical-logical method it may be possible to gain understanding about poverty in capitalism and its current evolution.

The Coolness of Capitalism Today

Directory of Open Access Journals (Sweden)

Jim McGuigan

2012-05-01

Full Text Available This paper is about the reconciliation of cultural analysis with political economy in Marxist-inspired research on communications. It traces how these two traditions became separated with the development of a one-dimensional and consumerist cultural studies, on the one-hand, and a more classically Marxist political economy of communications, on the other hand, that was accused of holding a simplistic and erroneous concept of ideology. The paper defends a conception of ideology as distorted communication motivated by unequal power relations and sketches a multidimensional mode of cultural analysis that takes account of the moments of production, consumption and textual meaning in the circulation of communications and culture. In accordance with this framework of analysis, the cool-capitalism thesis is outlined and illustrated with reference to Apple, the ‘cool’ corporation. And, the all-purpose mobile communication device is selected as a key and urgent focus of attention for research on commodity fetishism and labour exploitation on a global scale today.

Unveiled Risks in a Telecoupled Arena Dependent on Agricultural Commodity Trade

Science.gov (United States)

Batistella, M.; Silva, R. F. B. D.; Liu, J.; Moran, E. F.; Torres, S.; Dou, Y.

2017-12-01

In less than five years, a new field of interdisciplinary research has been widely developed within the coupled human-natural systems (CHANS) community. Based on well-known concepts acting over long distances, such as teleconnections for biophysical sciences and globalization for human sciences, the telecoupling framework states that long distant CHANS may be integrated through flows of capital, information, and matter, shaping environmental and socioeconomic changes within local systems. An international project including researchers from Brazil, China, United Kingdom (UK), and United States of America (USA) is using such a framework to study the flows of agricultural commodities between sending systems such as Brazil and the USA, and receiving systems such as China with soybean trade as a case in point. Many findings have already shown that these dynamics are intrinsically connected and changes in environmental conditions in one system may affect economic conditions in other systems. In the case of the double-crop practice (i.e., soybean followed by maize, two crops year round) used in some regions of Brazil, maize production is strongly connected with soybean production through the supply chain, logistics, producer regions, and farmers. Consequently, maize has been displaced to second-crop status, making it more vulnerable to rain shortfalls. The use of the telecoupling framework has also unveiled a possible threat for soybean production in the long run if it only relies on international demand and inputs. The telecoupled soybean production system has put some Brazilian farmers at economic risk, and is pushing them towards diversification and alternative production practices (e.g., non-GMO crops, biological control, in-farm seed production) to reduce their risk. This, in turn, may affect the demand-consumption relationship among traditional trading partners. With this paper, we also highlight the role of cascading effects and spillover systems of telecoupling in

Development of experimental concepts for investigating the strength behavior of fine-grained cohesive soil in the Spacelab/space shuttle zero-g environment

Science.gov (United States)

Bonaparte, R.; Mitchell, J. K.

1981-01-01

Three different sets of tests are proposed for the NASA Spacelab experimental program. The first of tests, designed to measure the true cohesion of several different soils, would be carried out in space through use of a specially prepared direct shear apparatus. As part of this first series of tests, it is recommended that a set of drained unconfined compression tests be performed terrestrially on the same soils as tested in space. A form of the direct tension test is planned to measure the true tensile strength of the same types of soils used in the first series of tests. The direct tension tests could be performed terrestrially. The combined results of the direct shear tests, direct tension tests, and unconfined compression tests can be used to construct approximate failure envelopes for the soils tested in the region of the stress origin. Relationships between true cohesion and true tensile strength can also be investigated. In addition, the role of physio-chemical variables should be studied. The third set of tests involves using a multiaxial cubical or true triaxial test apparatus to investigate the influence of gravity induced fabric anisotropy and stress nonhomogeneities on the stress strain behavior of cohesive soils at low effective stress levels. These tests would involve both in space and terrestrial laboratory testing.

[Health resorts in Styria, Charinthia and Istria once (1897) and today (2007).].

Fischinger, Ales; Fischinger, Janez; Fischinger, Dusa; Skrobonja, Ante

2008-01-01

The aim of this study is to determine which health resorts existed in 1897 in Istria, Carinthia and Styria region, how many of them are still in use today and how the spas and their offer were represented in the past and how they are represented today. The study is based on the textbook Balneotherapie II (Bibliothek des Arztes 1900) by prof. dr. Julius Glax. The second source of our study is based on the currently available presentation of the health resorts from the internet. The textbook Balneotherapie was intended for the post graduate education of physicians and general practitioners, so they could advise the patient on further treatment in an appropriate health resort. In the chapter Balneographie the author represented 1200 health resorts all over the world. From the book we have chosen the following regions: Istria, Carinthia and Styria which used to be three parts of the Austro-Hungarian Empire. Today they are divided in to three neighboring states: Croatia (Istria), Slovenia (Istria, Carinthia, Styria) and Austria (Carinthia, Styria). Within these regions Glax presented 22 health resorts, 19 of them are still working today. Barbarabad/Barbara bath (Carinthia, Austria) does not exist either as a resort or as a city. Rimske toplice (Römerbad/Roman baths) and Rimski vrelec (Römerquelle/ Roman springs) in Styria region do not function as health resorts any more. Nowadays we make a difference between spa and health resorts. Spa resorts offer numerous forms of recreation for better well being. Health resorts offer health services, as well as neglected, but various forms of alternative treatments and recreation. Each spa and health resort is represented in brochures and on the World Wide Web individually. Tradition is usually not mentioned, it is neglected but the exception is Opatija (Abbazia) which past is usually presented in the brochures. The museum of medical tourism was opened in November 2007 in Opatija where you can admire the development of Opatija

Enhancer Analysis Unveils Genetic Interactions between TLX and SOX2 in Neural Stem Cells and In Vivo Reprogramming

Summary The orphan nuclear receptor TLX is a master regulator of postnatal neural stem cell (NSC) self-renewal and neurogenesis; however, it remains unclear how TLX expression is precisely regulated in these tissue-specific stem cells. Here, we show that a highly conserved cis-element within the Tlx locus functions to drive gene expression in NSCs. We demonstrate that the transcription factors SOX2 and MYT1 specifically interact with this genomic element to directly regulate Tlx enhancer activity in vivo. Knockdown experiments further reveal that SOX2 dominantly controls endogenous expression of TLX, whereas MYT1 only plays a modulatory role. Importantly, TLX is essential for SOX2-mediated in vivo reprogramming of astrocytes and itself is also sufficient to induce neurogenesis in the adult striatum. Together, these findings unveil functional genetic interactions among transcription factors that are critical to NSCs and in vivo cell reprogramming. PMID:26607952

Large scale comparative codon-pair context analysis unveils general rules that fine-tune evolution of mRNA primary structure.

Directory of Open Access Journals (Sweden)

Gabriela Moura

Full Text Available BACKGROUND: Codon usage and codon-pair context are important gene primary structure features that influence mRNA decoding fidelity. In order to identify general rules that shape codon-pair context and minimize mRNA decoding error, we have carried out a large scale comparative codon-pair context analysis of 119 fully sequenced genomes. METHODOLOGIES/PRINCIPAL FINDINGS: We have developed mathematical and software tools for large scale comparative codon-pair context analysis. These methodologies unveiled general and species specific codon-pair context rules that govern evolution of mRNAs in the 3 domains of life. We show that evolution of bacterial and archeal mRNA primary structure is mainly dependent on constraints imposed by the translational machinery, while in eukaryotes DNA methylation and tri-nucleotide repeats impose strong biases on codon-pair context. CONCLUSIONS: The data highlight fundamental differences between prokaryotic and eukaryotic mRNA decoding rules, which are partially independent of codon usage.

Career development tips for today's nursing academic: bibliometrics, altmetrics and social media.

Smith, Derek R; Watson, Roger

2016-11-01

A discussion of bibliometrics, altmetrics and social media for the contemporary nursing scholar and academic researcher. Today's nursing academic faces myriad challenges in balancing their daily life and, in recent years, academic survival has been increasingly challenged by the various research assessment exercises that evaluate the performance of knowledge institutions. As such, it is essential that today's nursing academic keep up to date with the core competencies needed for survival in a modern research career, particularly the intersecting triad of bibliometrics, altmetrics and social media. Discussion paper. Published literature and relevant websites. The rise of social media and altmetrics has important implications for contemporary nursing scholars who publish their research. Some fundamental questions when choosing a journal might be 'does it have a Twitter and/or Facebook site, or a blog (or all three)'; and 'does it have any other presence on social media, such as LinkedIn, Wikipedia, YouTube, ResearchGate and so on?' Another consequence of embracing social media is that individual academics should also develop their own strategies for promoting and disseminating their work as widely as possible. The rising importance of social media and altmetrics can no longer be ignored, and today's nursing academic now has another facet to consider in their scholarly activities. Despite the changing nature of research dissemination, however, it is still important to recognize the undoubted value of established knowledge dissemination routes (that being the peer-reviewed publication). © 2016 John Wiley & Sons Ltd.

Religious Renaissance in China Today

Directory of Open Access Journals (Sweden)

Richard Madsen

2011-01-01

Full Text Available Since the beginning of the Reform Era in 1979, there has been a rapid growth and development of religious belief and practice in China. A substantial new scholarly literature has been generated in the attempt to document and understand this. This essay identifies the most important contributions to that literature and discusses areas of agreement and controversy across the literature. Along with new data, new paradigms have developed to frame research on Chinese religions. The paradigm derived from C. K. Yang’s classic work in the 1960s came from structural functionalism, which served to unite research in the humanities and social sciences. However, structural functionalism has been abandoned by the new generation of scholars. In the humanities, the most popular paradigm derives from Michel Foucault, but there are also scholars who use neo-Durkheimian and neo-Weberian paradigms. In the social sciences, the dominant paradigms tend to focus on state-society relations. None of these paradigms fully captures the complexity of the transformations happening in China. We recommend greater dialogue between the humanities and social sciences in search of more adequate theoretical frameworks for understanding Chinese religions today.

The Extreme Universe Space Observatory onboard the Japanese Experiment Module (JEM-EUSO) is an international mission designed to explore the origin and nature of the of ultra high-energy cosmic rays (UHECR), with energies E>5.5x10{sup 19} eV, aiming at an integrated exposure of {approx}10{sup 6} km{sup 2} sr yr at E>10{sup 20} eV. Consisting of a near-UV 2.65 m diameter telescope with a field of view of 60{sup o}, JEM-EUSO looks down from space, monitoring the dark side of the Earth, to detect the fluorescence and Cherenkov light emitted along the linear track generated by a cosmic particle traversing the atmosphere. The energy and the arrival direction of each particle will be measured while the all 4{pi} sky is monitored. The primary science goal of the mission is to identify the sources of the highest energy particles, and to measure their flux and spectrum, to unveil the mechanisms for the production, acceleration, and in situ propagation of these extreme particles. Other exploratory objectives of the mission include the study of the galactic and local extragalactic magnetic field; the detection of high-energy gamma rays and neutrinos, and tests of relativity and quantum gravity effects at extreme energies. Other aspects of fundamental physics that will be studied include the top-down models and the behavior of the neutrino cross sections at extreme energies. JEM-EUSO is also expected to conduct a systematic survey of the not yet well known energetic phenomena of the Earth's atmosphere. The mission is currently in the phase A study by JAXA and has been included in the ELIPS research pool of the European Space Agency. JEM-EUSO will be launched by an H2B rocket in the Japanese fiscal year 2016 and will be transferred to the ISS by an H2 Transfer Vehicle (HTV). It will be attached to the external experiment platform of the Japanese 'KIBO' module of the ISS. In this paper we summarize the science case, the science objectives, the technological and

From 5.5 months of dual-band optical photometric monitoring at the 1 mmag level, BRITE-Constellation has revealed two simultaneous types of variability in the O4I(n)fp star ζ Puppis: one single periodic non-sinusoidal component superimposed on a stochastic component. The monoperiodic component is the 1.78-d signal previously detected by Coriolis/Solar Mass Ejection Imager, but this time along with a prominent first harmonic. The shape of this signal changes over time, a behaviour that is incompatible with stellar oscillations but consistent with rotational modulation arising from evolving bright surface inhomogeneities. By means of a constrained non-linear light-curve inversion algorithm, we mapped the locations of the bright surface spots and traced their evolution. Our simultaneous ground-based multisite spectroscopic monitoring of the star unveiled cyclical modulation of its He II λ4686 wind emission line with the 1.78-d rotation period, showing signatures of corotating interaction regions that turn out to be driven by the bright photospheric spots observed by BRITE. Traces of wind clumps are also observed in the He II λ4686 line and are correlated with the amplitudes of the stochastic component of the light variations probed by BRITE at the photosphere, suggesting that the BRITE observations additionally unveiled the photospheric drivers of wind clumps in ζ Pup and that the clumping phenomenon starts at the very base of the wind. The origins of both the bright surface inhomogeneities and the stochastic light variations remain unknown, but a subsurface convective zone might play an important role in the generation of these two types of photospheric variability.

ESA Unveils Its New Comet Chaser.

Science.gov (United States)

1999-07-01

The objective is to study one of these primordial objects at close quarters by placing a lander on its surface and chasing, with an orbiter, the comet for millions of kilometres through space. Comets - among the oldest (4.6 billion years!) and last altered objects in the solar system - are regarded as the building blocks from which the planets formed. Thus the Rosetta's discoveries will allow the scientists to learn more about birth and evolution of the planets and about the origin of life on the Earth. The final design of the Rosetta orbiter will be revealed for the first time at the Royal Society in London on 1 July when a 1:4 scale model will be unveiled by ESA's Director of Science, Prof.. Roger Bonnet. (The full size version of the spacecraft is 32 metres across, so large that it would stretch the entire width of a football pitch. Almost 90 of this is accounted for by the giant solar panels which are needed to provide electrical power in the dark depths of the Solar System). "Rosetta is a mission of major scientific importance," said Prof. Bonnet. "It will build on the discoveries made by Giotto and confirm ESA's leading role in the exploration of the Solar System and the Universe as a whole." The timing of this event has been chosen to coincide with the London meeting of the Rosetta Science Working Team and the second Earth flyby of the now non-operational Giotto spacecraft. In addition, the opening of the British Museum's 'Cracking Codes' Exhibition, for which the Rosetta Stone is the centrepiece, is set to take place on 10 July. The Rosetta mission. Rosetta is the third Cornerstone in ESA's 'Horizon 2000' long-term scientific programme. It will be launched by Ariane 5 rocket from Kourou spaceport in French Guiana in January 2003. In order to gain sufficient speed to reach the distant comet, Rosetta will require gravity assists from the Earth (twice) and Mars. After swinging around Mars in May 2005, Rosetta will return to Earth's vicinity in October 2005 and

An Introduction to Flight Software Development: FSW Today, FSW 2010

Science.gov (United States)

Gouvela, John

2004-01-01

Experience and knowledge gained from ongoing maintenance of Space Shuttle Flight Software and new development projects including Cockpit Avionics Upgrade are applied to projected needs of the National Space Exploration Vision through Spiral 2. Lessons learned from these current activities are applied to create a sustainable, reliable model for development of critical software to support Project Constellation. This presentation introduces the technologies, methodologies, and infrastructure needed to produce and sustain high quality software. It will propose what is needed to support a Vision for Space Exploration that places demands on the innovation and productivity needed to support future space exploration. The technologies in use today within FSW development include tools that provide requirements tracking, integrated change management, modeling and simulation software. Specific challenges that have been met include the introduction and integration of Commercial Off the Shelf (COTS) Real Time Operating System for critical functions. Though technology prediction has proved to be imprecise, Project Constellation requirements will need continued integration of new technology with evolving methodologies and changing project infrastructure. Targets for continued technology investment are integrated health monitoring and management, self healing software, standard payload interfaces, autonomous operation, and improvements in training. Emulation of the target hardware will also allow significant streamlining of development and testing. The methodologies in use today for FSW development are object oriented UML design, iterative development using independent components, as well as rapid prototyping . In addition, Lean Six Sigma and CMMI play a critical role in the quality and efficiency of the workforce processes. Over the next six years, we expect these methodologies to merge with other improvements into a consolidated office culture with all processes being guided by

Academic dishonesty today, unethical practices tomorrow?

LaDuke, Rebekah D

2013-01-01

The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. Copyright © 2013 Elsevier Inc. All rights reserved.

Competing roles of coevolution, selective pressure and recombination are an emerging interest in virus evolution. We report a novel aviadenovirus from captive red-bellied parrots (Poicephalus rufiventris) that uncovers evidence of deep recombination among aviadenoviruses. The sequence identity of the virus was most closely related to Turkey adenovirus D (42% similarity) and other adenoviruses in chickens, turkeys and pigeons. Sequencing and comparative analysis showed that the genome comprised 40,930 nucleotides containing 42 predicted open reading frames (ORFs) 19 of which had strong similarity with genes from other adenovirus species. The new genome unveiled a lineage that likely participated in deep recombination events across the genus Aviadenovirus accounting for an ancient evolutionary relationship. We hypothesize frequent host switch events and recombination among adenovirus progenitors in Galloanserae hosts caused the radiation of extant aviadenoviruses and the newly assembled Poicephalus adenovirus genome points to a potentially broader host range of these viruses among birds. - Highlights: •Shows how a single new genome can change overall phylogeny. •Reveals host switch events among adenovirus progenitors in Galloanserae hosts. •Points to a potentially broader host range of adenoviruses among birds and wildlife .

Nutritional deficiency and infectious diseases constitute major paediatric priorities in most developing countries in Africa today. It is suggested that successful implementation of the various cost-effective intervention programmes which address themselves to these priorities will gradually unveil other paediatric problems presently considered of low priority. These will include the malignant diseases of childhood. The very high cost of cancer detection and treatment will demand carefully reasoned and planned approaches in most Third World countries. The implications of this in relation to childhood malignancies in Africa are discussed.

[Health care in today's Western Belarus in the inter-war period (1921-1939)].

Science.gov (United States)

Tiszczenko, E M

2001-01-01

During the inter-war period, today's Western Belarus, which under the Treaty of Riga constituted part of the Second Polish Republic, stood out for its higher morbidity in various disease categories than other regions of the country. Heightened threats of epidemics prevailed in that area, and typhoid fever, trachoma, tuberculois and venereal disease were serious health problems. Specific features of the health care of today's Western Belarus could be observed that set it apart from both that of Eastern Belarus forming a part of the Soviet Union as well as from the central and western provinces of Poland. Compared with Eastern Belarus, there was a lack of health services, including anti-tuberculosis, anti-venereal and paediatric dispensaries, or they were in the process of being created. But physicians' self-government bodies functioned, as did out-patient care with dispensary-like elements and health care provided by local health centres. There also existed the institution of full-time family doctors within the insured health-care system - something lacking in Eastern Belarus. As in other voivodships (provinces) of the Second Republic, there existed multi-sector health care: state, local, insurance-based and private. The Western Belarus had Poland's smallest number of physicians, new hospital beds and pharmacies. On the other hand, today's Western Belarus stands out by virtue of maintaining field-medicine traditions. To this day, assistant medical officers provide health care to the rural population - an arrangement not typical of the central and western provinces fo pre-war Poland.

Skateboarding injuries of today

Forsman, L; Eriksson, A

2001-01-01

Background—Skateboarding injuries have increased with the rise in popularity of the sport, and the injury pattern can be expected to have changed with the development of both skateboard tricks and the materials used for skateboard construction. Objective—To describe the injury pattern of today. Methods—The pattern of injuries, circumstances, and severity were investigated in a study of all 139 people injured in skateboarding accidents during the period 1995–1998 inclusive and admitted to the University Hospital of Umeå. This is the only hospital in the area, serving a population of 135 000. Results—Three of the 139 injured were pedestrians hit by a skateboard rider; the rest were riders. The age range was 7–47 years (mean 16). The severity of the injuries was minor (AIS 1) to moderate (AIS 2); fractures were classified as moderate. The annual number of injuries increased during the study period. Fractures were found in 29% of the casualties, and four children had concussion. The most common fractures were of the ankle and wrist. Older patients had less severe injuries, mainly sprains and soft tissue injuries. Most children were injured while skateboarding on ramps and at arenas; only 12 (9%) were injured while skateboarding on roads. Some 37% of the injuries occurred because of a loss of balance, and 26% because of a failed trick attempt. Falls caused by surface irregularities resulted in the highest proportion of the moderate injuries. Conclusions—Skateboarding should be restricted to supervised skateboard parks, and skateboarders should be required to wear protective gear. These measures would reduce the number of skateboarders injured in motor vehicle collisions, reduce the personal injuries among skateboarders, and reduce the number of pedestrians injured in collisions with skateboarders. Key Words: skateboard; injury; prevention PMID:11579065

Earthquake history of the Republic of Ragusa (today Dubrovnik, Croatia) (Invited)

Science.gov (United States)

Albini, P.; Rovida, A.; Locati, M.

2009-12-01

Among the towns constellating the Dalmatian coast, Ragusa (today Dubrovnik, Croatia), stands out, both because of its location in the middle of the Eastern Adriatic coast and its long-lasting, independent history of a Modern Age town and its small coastal territory. An important intelligence crossroads, squeezed as it was in between powerful and influential neighbours, such as the Ottoman Empire and the Republic of Venice, in its history (1358-1808) the Republic of Ragusa did experience heavily damaging earthquakes. We narrate the story of these earthquakes, which were recorded in the historical documentation of the Republic (today stored at the State Archives of Dubrovnik - Drzavni arhiv u Dubrovniku) as well as in documents from officers of other Mediterranean countries and letters of individuals. Of special note is the 6 April 1667 earthquake, which inflicted a permanent scar on the Republic. The earthquake's direct effects and their consequences caused a serious financial crisis, so critical that it took over 50 years for Ragusa to recover. This large earthquake is reappraised on the basis of newly investigated sources, and effects of the damage within the city walls are detailed. A seismic history of Ragusa is finally proposed, supported by full-text coeval records.

The development and negotiation of an Engineering, Procurement and Construction (EPC) contract is a multi-disciplined and time consuming process. Relative to the first wave on new nuclear build projects of the 1950's - 1970's, today's EPC contracts are more complex for a variety of reasons including more demanding regulatory and environmental requirements, global supply chain versus localization issues and different world wide economic considerations. This paper discusses the impacts of some of these challenges on developing an EPC contract in today's Nuclear Renaissance. (authors)

2010-01-01

Radioactive hydrogen isotope, tritium is one of the radionuclides which is the most released in the environment during the normal operation of nuclear facilities. The increase of nuclear activities and the development of future generations of reactors, like the EPR and ITER, would lead to a significant increase of tritium effluents in the atmosphere and in the natural waters, thus raising many worries and questions. Aware about the importance of this question, the national association of local information commissions (ANCLI) wished to make a status of the existing knowledge concerning tritium and organized in 2008 a colloquium at Orsay (France) with an inquiring approach. The scientific committee of the ANCLI, renowned for its expertise skills, mobilized several nuclear specialists to carry out this thought. This book represents a comprehensive synthesis of today's knowledge about tritium, about its management and about its impact on the environment and on human health. Based on recent scientific data and on precise examples, it treats of the overall questions raised by this radionuclide: 1 - tritium properties and different sources (natural and anthropic), 2 - the problem of tritiated wastes management; 3 - the bio-availability and bio-kinetics of the different tritium species; 4 - the tritium labelling of environments; 5 - tritium measurement and modeling of its environmental circulation; 6 - tritium radio-toxicity and its biological and health impacts; 7 - the different French and/or international regulations concerning tritium.

Dynamic brain electrical impedance tomography (EIT) is a promising technique for continuously monitoring the development of cerebral injury. While there are many reconstruction algorithms available for brain EIT, there is still a lack of study to compare their performance in the context of dynamic brain monitoring. To address this problem, we develop a framework for evaluating different current algorithms with their ability to correctly identify small intracranial conductivity changes. Firstly, a simulation 3D head phantom with realistic layered structure and impedance distribution is developed. Next several reconstructing algorithms, such as back projection (BP), damped least-square (DLS), Bayesian, split Bregman (SB) and GREIT are introduced. We investigate their temporal response, noise performance, location and shape error with respect to different noise levels on the simulation phantom. The results show that the SB algorithm demonstrates superior performance in reducing image error. To further improve the location accuracy, we optimize SB by incorporating the brain structure-based conductivity distribution priors, in which differences of the conductivities between different brain tissues and the inhomogeneous conductivity distribution of the skull are considered. We compare this novel algorithm (called SB-IBCD) with SB and DLS using anatomically correct head shaped phantoms with spatial varying skull conductivity. Main results and Significance: The results showed that SB-IBCD is the most effective in unveiling small intracranial conductivity changes, where it can reduce the image error by an average of 30.0% compared to DLS.

Base programs at ATR are planned well into the 21st century. The ATR and support facilities along with an overview of current programs will be reviewed, but the main focus of the presentation will be on the impact that today's economic and regulatory concerns have had on the operation of this test reactor. Today's economic and regulatory concerns have demanded more work be completed at lower cost while increasing the margin of safety. By the beginning of the 1990 s, federal budgets for research generally and particularly for nuclear research had decreased dramatically. Many national needs continued to require testing in the ATR; but demanded lower cost, increased efficiency, improved performance, and an increased margin of safety. At the same time budgets were decreasing, there was an increase in regulatory compliance activity. The new standards imposed higher margins of safety. The new era of greater openness and higher safety standards complemented research demands to work safer, smarter and more efficiently. Several changes were made at the ATR to meet the demands of the sponsors and public. Such changes included some workforce reductions, securing additional program sponsors, upgrading some facilities, dismantling other facilities, and implementing new safety programs. (author)

[Poliomyelitis in Landsteiner's time and today].

Schwick, H G

1991-01-01

At a meeting of the Royal and Imperial Association of Physicians in Vienna on December 18, 1908 Dr. Karl Landsteiner reported on the successful experimental transmission of poliomyelitis from man to ape in a study which he undertook together with Erwin Popper. In a scientific article that was published shortly after the meeting, Landsteiner wrote that "the poliomyelitis virus belongs to the group of filterable micro-organisms". Soon, Landsteiner's results were confirmed by other colleagues. During a congress in Washington 1912 Landsteiner declared that the development of a vaccine against poliomyelitis might prove difficult but was certainly possible in his opinion. It took another 45 years before the first polio vaccine was available (1955 Salk) and another 5 years until the oral vaccine (1960 Sabin) was implemented. The incidence of poliomyelitis decreased dramatically in industrial countries as a result of vaccination. Today, poliomyelitis is still an enormous threat in developing countries. Together with many national and international institutions the WHO fights this situation very hard by means of vaccination campaigns. The incidence of side effects and insufficient reactions is small with both vaccines. New techniques in the field of molecular biology and a good knowledge of the poliovirus make it likely that further improvements on the vaccines which are currently available will take place.

The most critical issues facing managers in South Africa today

Directory of Open Access Journals (Sweden)

2002-12-01

Full Text Available South African managers today find themselves squeezed between juxtapositions, such as international competition and simultaneous skill development programmes to combat illiteracy. A second example is high unemployment and the concurrent shortage of IT specialists. Affirmative action has led to troublesome labour relations. HIV/AIDS has an enormous impact on business and must be managed. South African managers need to change their managerial approaches to cope with the increasing demands of this country. Managers must be aware of the realities facing them and know how to turn them into potential growth opportunities for their organisations and South Africa as a country.

Microevolution analysis of Bacillus coahuilensis unveils differences in phosphorus acquisition strategies and their regulation

Full Text Available Bacterial genomes undergo numerous events of gene losses and gains that generate genome variability among strains of the same species (microevolution. Our aim was to compare the genomes and relevant phenotypes of three Bacillus coahuilensis strains from two oligotrophic hydrological systems in the Cuatro Ciénegas Basin (México, to unveil the environmental challenges that this species cope with, and the microevolutionary differences in these genotypes. Since the strains were isolated from a low P environment, we placed emphasis on the search of different phosphorus acquisition strategies. The three B. coahuilensis strains exhibited similar numbers of coding DNA sequences, of which 82% (2, 893 constituted the core genome, and 18% corresponded to accessory genes. Most of the genes in this last group were associated with mobile genetic elements or were annotated as hypothetical proteins. Ten percent of the pangenome consisted of strain-specific genes. Alignment of the three B. coahuilensis genomes indicated a high level of synteny and revealed the presence of several genomic islands. Unexpectedly, one of these islands contained genes that encode the 2-keto-3-deoxymannooctulosonic acid (Kdo biosynthesis enzymes, a feature associated to cell walls of Gram-negative bacteria. Some microevolutionary changes were clearly associated with mobile genetic elements. Our analysis revealed inconsistencies between phenotype and genotype, which we suggest result from the impossibility to map regulatory features to genome analysis. Experimental results revealed variability in the types and numbers of auxotrophies between the strains that could not consistently be explained by in silico metabolic models. Several intraspecific differences in preferences for carbohydrate and phosphorus utilization were observed. Regarding phosphorus recycling, scavenging, and storage, variations were found between the three genomes. The three strains exhibited differences regarding

Artificial insemination in pigs today.

Knox, R V

2016-01-01

Use of artificial insemination (AI) for breeding pigs has been instrumental for facilitating global improvements in fertility, genetics, labor, and herd health. The establishment of AI centers for management of boars and production of semen has allowed for selection of boars for fertility and sperm production using in vitro and in vivo measures. Today, boars can be managed for production of 20 to 40 traditional AI doses containing 2.5 to 3.0 billion motile sperm in 75 to 100 mL of extender or 40 to 60 doses with 1.5 to 2.0 billion sperm in similar or reduced volumes for use in cervical or intrauterine AI. Regardless of the sperm dose, in liquid form, extenders are designed to sustain sperm fertility for 3 to 7 days. On farm, AI is the predominant form for commercial sow breeding and relies on manual detection of estrus with sows receiving two cervical or two intrauterine inseminations of the traditional or low sperm doses on each day detected in standing estrus. New approaches for increasing rates of genetic improvement through use of AI are aimed at methods to continue to lower the number of sperm in an AI dose and reducing the number of inseminations through use of a single, fixed-time AI after ovulation induction. Both approaches allow greater selection pressure for economically important swine traits in the sires and help extend the genetic advantages through AI on to more production farms.

Speckle metrology in the nanoworld, as it is perceived today, and how it may affect industry

Pryputniewicz, Ryszard J.

2010-09-01

My memory goes back to my early collage studies that were almost entirely on the scale of "macroworld", as we practiced/perceived it some four decades ago. Since that time things have changed a lot constantly decreasing the scales of interest, at times at rather rapid pace, with monumental advances leading to the scales we work with today and plan for tomorrow. During that change/transition there were "meso" and "micro" developments characterized by changes in scales/sizes of things of interest. Today's scale of interest is "nano" and we are already not only working with "picotechnology", but are even reaching beyond while constantly "planning and projecting" the scales/worlds of the future. Advancement of any technology, especially new emerging ones as we witness/experience them today, is facilitated by the use of all available solution strategies. One of the emerging strategies that affect almost anything currently being developed and/or used, in the today's nanoworld, is based on recent advances of microelectromechanical systems (MEMS). Today MEMS affect almost everything we do from household appliances, via cars we drive and planes that whisk us from continent to continent, to spaceships used for search of/and exploration of other worlds. The modern microsensors are also used to explore for and produce petroleum products that are used in multitude of today's applications. To facilitate these advances a great majority of MEMS is used in the form of sensors. However development of MEMS in general and sensors in particular poses one of the greatest challenges in today's experimental mechanics. Among MEMS, the greatest contemporary interest is in the area of inertial sensors because they have numerous uses ranging from everyday applications to highly specialized ones, including many industrial platforms. As such they have tremendous potential to affect future of humanity. However, advances in MEMS, such as pressure and temperature sensors as well as gyroscopes and

1996-01-01

As the culmination of five years of developmental work by Cummins Engines, BC Research Inc., and BC Gas Utility Ltd., a T800 Kenworth truck was outfitted with a new Cummins L10G natural gas engine, and two lightweight fully -wrapped Dynetek cylinders; it was pronounced to be 'a viable clean truck today'. The L10G spark-ignited engine operates at a relatively high peak efficiency of 37 per cent and is commercially available to meet the current California Air Resources Board heavy duty vehicle emission standards without the use of a catalytic converter. The L10G engine produces no particulate emissions, a very significant advantage, in view of the fact that particulate emissions have been identified as major contributors to respiratory ailments

How Knowledge of Ancient Egyptian Women Can Influence Today's Gender Role: Does History Matter in Gender Psychology?

Science.gov (United States)

Khalil, Radwa; Moustafa, Ahmed A; Moftah, Marie Z; Karim, Ahmed A

2016-01-01

A gender role is a set of societal norms dictating what types of behaviors are considered desirable or appropriate for a person based on their sex. However, socially constructed gender roles can lead to equal rights between genders but also to severe disadvantages and discrimination with a remarkable variety between different countries. Based on social indicators and gender statistics, "women in the Arab region are on average more disadvantaged economically, politically, and socially than women in other regions." According to Banduras' social learning theory, we argue that profound knowledge of the historical contributions of Ancient Egyptian female pioneers in science, arts, and even in ruling Egypt as Pharaohs can improve today's gender role in Egypt and Middle Eastern countries. Therefore, this article provides an elaborate review of the gender role of women in Ancient Egypt, outlining their prominence, influence, and admiration in ancient societies, and discusses the possible psychological impact of this knowledge on today's gender role. We suggest that future empirical research should investigate how enhancing the knowledge of women from Ancient Egypt can improve today's gender role in Egypt and the Middle East. Bandura's social learning theory is outlined as a possible framework for future research.

Listening to the community: a first step in adapting Diabetes Today to the Pacific.

Braun, Kathryn L; Kuhaulua, Rie L; Ichiho, Henry M; Aitaoto, Nia T

2002-09-01

Diabetes is a growing problem among Pacific Islanders, but few community-based groups in the Pacific are actively working on diabetes prevention and control. The Pacific Diabetes Today Resource Center (PDTRC) was established in 1998 to adapt the Diabetes Today (DT) curriculum for Pacific Island communities in Hawai'i, American Samoa, and Micronesia. To gather data to guide the development of the Pacific Diabetes Today (PDT) curriculum, a year was spent listening to Pacific communities. First, data were gathered from health professionals on how the DT curriculum should be modified. Second, health and community leaders in 11 sites were trained and supported to conduct discussion groups with people affected by diabetes. Third, site coordinators evaluated the discussion group process. A Pacific-wide Advisory Council (AC) was established to guide the project, and the AC used findings from the first year to generate guidelines for staff to follow in adapting the DT curriculum to the Pacific. These guidelines directed staff to: a) realize that Pacific communities need to build awareness about diabetes; b) train and support local community leaders as co-facilitators in the PDT curriculum, using a learn-by-doing approach, with the goal of developing them as independent trainers; c) encourage the involvement of a broad range of community members in PDT training, including the involvement of local physicians to counter medical misconceptions about diabetes; d) give the PDT curriculum a Pacific "look" and "feel;" and e) keep the training logistically flexible to accommodate differences in communities across the region. Other programs and agencies that want to develop training programs in the Pacific may find these listening strategies and guidelines helpful.

Full Text Available Ancient Azerbaijanian music was found after archelogical excavations. In the first literature The Book of Dede Korkut, then in Nizami's and Fuzuli's literal works a vast of information could be found about the Medieval Age music. The first phase of Azerbaijanian musical history contains arts of bards, laters phases contains classical modes. The researches of Azerbaijanian modes extend to the Medieval Age. The expand of 19th century European music affected Azerbaijanian culture, too. The early years of 20th century is reckoned as a new rising period in Azerbaijanin music. Uzeyir Hacibeyov composed Leyli and Majnun in that period which was the first opera of the East. Meanwhile, several musical high schools, conservatories, symphony orchestras, national instrumental orchestras, and theatres were established. The smphonic music which was established in 1920's had a major development in between 1940 and 1960. In between 1960 and 1980, younger generation, too, participated in artistic activities, alongside the older generation. In 1988-1994 Armenians invaded Karabagh and commited several genocides which some of the most known are called 20 January and Khojaly genocides. In that period, Azerbaijanian composes divided into three stages as 20 January, Karabagh, and Khojaly. Today, Azerbaijanian music is well known all over the world, while being played in lots of festivals in the whole world.

HOW UNIVERSAL ARE THE UNIVERSAL HUMAN RIGHTS TODAY?

Full Text Available This paper aims to contribute to a constructive debate on human rights. The two World Wars of the last century brought about the creation of the United Nations aimed “to reaffirm faith in fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women and of nations large and small”. Only three years later the Universal Declaration of the Human Rights was elaborated and promoted by the UN, considered to be the foundation of international human rights law. Today, as globalization brings all closer together in a “global village”, one can see that there are many ways to perceive and guarantee human rights, in different states, but also within different states. Poverty, illiteracy, censorship, cruel treatment and even the lack of guarantee for the right to life are, unfortunately, the norm for many people of the world. Such observations bring up questions regarding the legitimacy, universality and coherence of human rights.

U.S. bioremediation market: Yesterday, today, and tomorrow

International Nuclear Information System (INIS)

Devine, K.

1995-01-01

The use of bioremediation for full-scale cleanup has increased dramatically throughout the past 10 years. This growth in activity is expected to continue through the year 2000. It is estimated that fewer than 10 companies offered field-level bioremedial services prior to 1985. Although the market today still is dominated by a small number of companies, the total number of firms claiming to offer services and/or products for bioremediation purposes has grown to over 1,000. It is estimated that aggregate bioremediation revenues for 1994 through 2000 will equal $2 to $3 billion (1994 dollars). This revenue will be generated in the initial part of this 7-year period primarily from underground storage cleanup, with revenues from hazardous waste sites becoming an increasingly important factor by accounting for the majority of revenues in the latter years. Market opportunities exist in technology development and implementation including biosparging, centralized treatment facilities for petroleum-contaminated soils, biofilters, and improvements in the cost-effectiveness of the technology

Esta cuestión de Hitler en la actualidad posee diversos problemas históricos que están íntimamente conectados con otros morales. En este trabajo, sin embargo, pretendo concentrarme primordialmente en su dimensión histórica. A la luz del sorprendente ascenso de Hitler en la moderna conciencia histórica, esto puede llevarnos a la siguiente pregunta: ¿No hemos otorgado al dictador nazi un poder aún mayor que cuando estaba vivo y comandando sus divisiones de la Wehrmacht en el punto culminante de sus conquistas?___________________ABSTRACT:By the end of the twentieth century, it can be said, Hitler was more alive and prominent than at the height of his power a half-century before. How did Hitler become this way? Isn’t he dead? How can he become so prominent more than half a century after his death? The issue of Hitler today poses several historical problems that are deeply moral problems as well. In this work, however, I intend to concentrate primarily on their historical dimension. In light of Hitler’s astonishing rise in modern historical consciousness, this leads to the inevitable question: Have we not granted to Hitler a far greater power over us than ever he had when he was alive and commanding his Wehrmacht divisions at the farthest extent of his conquests?

2010-09-01

As members of professional organizations such as American Society of Primatologists (ASP) and the International Primatological Society (IPS), primatologists must adhere to a set of nonhuman primate-focused principles outlined in resolutions and policy statements on, for example, the ethical treatment of nonhuman primates. Those of us that work in the field must also address issues such as the protection of primate health in the wild and the conservation of wild primate populations. Moreover, we increasingly find ourselves in complex situations where we must balance human and nonhuman primate needs and interests. The selection of commentary pieces in this edition of the American Journal of Primatology originated from presentations given in the symposium, Field Primatology of Today: Navigating the Ethical Landscape, held at the 32nd Annual Meeting of the American Society of Primatologists (ASP) in September 2009. The goals of that symposium and these resulting commentary pieces are threefold: (1) to revive a discussion of key contemporary ethical issues faced by field primatologists, (2) to highlight the need for centrally placed ethical considerations in various facets of our professional lives, particularly research and teaching, and (3) to consider what a comprehensive ethical code that addresses all of these issues might look like.

Introduction: The Continued Importance of Smallholders Today

Jacqueline M. Vadjunec

2016-10-01

Full Text Available Smallholders remain an important part of human-environment research, particularly in cultural and political ecology, peasant and development studies, and increasingly in land system and sustainability science. This introduction to the edited volume explores land use and livelihood issues among smallholders, in several disciplinary and subfield traditions. Specifically, we provide a short history of smallholder livelihood research in the human-environment tradition. We reflect on why, in an age of rapid globalization, smallholder land use and livelihoods still matter, both for land system science and as a reflection of concerns with inequality and poverty. Key themes that emerge from the papers in this volume include the importance of smallholder farming and land-use practices to questions of environmental sustainability, the dynamic reality of smallholder livelihoods, the challenges of vulnerability and adaptation in contemporary human-environment systems, and the structural and relative nature of the term “smallholder.” Overall these contributions show that smallholder studies are more pertinent than ever, especially in the face of global environmental change. Additionally, we argue that questions of smallholder identity, social difference, and teleconnections provide fertile areas of future research. We conclude that we need to re-envision who the smallholder is today and how this translates into modern human-environment smallholder studies.

Financial Management in Children: Today Need, Tomorrow Necessity

2015-05-01

Full Text Available Nearly 80% of young people today will never be able to retire. Why? Because they lack the personal finance training that leads to long-term planning and future security. Connecting the dots between kids and money management skills prepares them for the financial realities the world will face over the next century. Pocket money is one of the first ways for children to learn the basics of managing money – a skill they’ll definitely need for life – and it makes children feel independent. Whether to give pocket money, and at what age, and how much to give are issues that often concern parents. There are many ways to handle this. To a large extent it depends on family values, practices and finances. The main reason for giving children pocket money is to help children learn to be able to manage money while they are still young and parents can guide them. It also may help children to feel that they are important members of the family, because they are given part of the family's spending money.

Cardiological-interventional therapy of coronary artery disease today

International Nuclear Information System (INIS)

Reynen, K.; Henssge, R.

1999-01-01

The current importance of the interventional therapy of coronary artery disease may be deduced from the exponential increase in procedures performed in Germany in the last decade - at least 125,840 in 1996. Today, by improved catheter and balloon materials as well as by growing experience of the cardiologists, even complex lesions may be treated. Limitations of balloon angioplasty include acute vessel closure and restenosis - newer angioplasty devices like directional or rotational atherectomy or excimer-laser angioplasty did not overcome these limitations; only by coronary stenting, acute vessel closure could be managed and the likelihood of restenosis - at least in particular groups of patients - could be reduced. For a few years, intracoronary brachytherapy of the segments dilated with beta- or gamma-emitters has been seeking to reduce restenosis rate; the department of cardiology of the Dresden Cardiovascular Institute is participating in such a multicentre study using the beta-emitter 188 renium. Further main topics of our department represent primary angioplasty in patients with acute myocardial infarction and invasive diagnostic or interventional procedures by the transradial approach.

The Purex process very quickly and very widely supplanted the other concepts considered for nuclear fuel reprocessing after the presentation made at the Geneva Conference in 1955. The selectivity and radiolytic stability of tributylphosphate (T.B.P) clearly appeared to augur an extremely attractive process for completing the separation of valuable elements in the irradiated fuel. The concept has confirmed its validity, and subsequently its ability to adapt to changing requirements or constraints. Its industrial viability is in fact unquestioned today: Purex process is the basis of all the reprocessing plants in operation or planned throughout the world, and recent commissioning of the UP3 plant in France, in remarkable conditions, attests to such a level of maturity that one is tempted to ask the question: ``What remains to be proved, discovered or improved in the core of the Purex process?``.

Ancient water supports today's energy needs

The water footprint for fossil fuels typically accounts for water utilized in mining and fuel processing, whereas the water footprint of biofuels assesses the agricultural water used by crops through their lifetime. Fossil fuels have an additional water footprint that is not easily accounted for: ancient water that was used by plants millions of years ago, before they were transformed into fossil fuel. How much water is mankind using from the past to sustain current energy needs? We evaluate the link between ancient water virtually embodied in fossil fuels to current global energy demands by determining the water demand required to replace fossil fuels with biomass produced with water from the present. Using equal energy units of wood, bioethanol, and biodiesel to replace coal, natural gas, and crude oil, respectively, the resulting water demand is 7.39 × 1013 m3 y-1, approximately the same as the total annual evaporation from all land masses and transpiration from all terrestrial vegetation. Thus, there are strong hydrologic constraints to a reliance on biofuel energy produced with water from the present because the conversion from fossil fuels to biofuels would have a disproportionate and unsustainable impact on the modern water. By using fossil fuels to meet today's energy needs, we are virtually using water from a geological past. The water cycle is insufficient to sustain the production of the fuel presently consumed by human societies. Thus, non-fuel-based renewable energy sources are needed to decrease mankind's reliance on fossil fuel energy without placing an overwhelming pressure on global freshwater resources.

Heat and power systems commonly found in today's corn processing facilities, sugar mills, and pulp and paper mills will be reviewed. We will also examine concepts for biorefineries of the future. We will show that energy ratio, defined as the ratio of renewable energy produced divided by the fossil energy input, can vary widely from near unity to values greater than 12. Renewable-based utility systems combined with low-fossil input agricultural systems lead to high-energy ratios.

2001-01-01

Alberta's industrial project scene from 1981 to 2000 was presented in this power point presentation with particular focus on proposed bitumen recovery projects and heavy oil project challenges. A graph depicting GTG world orders by region (Americas, Asia and Europe) showed that U.S. market continues to drive global growth. Major industrial projects in Alberta were highlighted and employment requirements by sector were outlined. In addition, mitigation measures that are needed to successfully deal with the unique challenges of today's market were described. It was noted that in recent years lower capital expenditure by the industry in general has resulted in corporate downsizing or mergers which in turn have resulted in lower technical and operational knowledge. Some of the current challenges facing the industry are new demands for water treatment expertise and an aging workforce. It was concluded that effective mitigation will require a disciplined approach within a flexible framework.1 tab., 7 figs

Thomas L Petty's lessons for the respiratory care clinician of today.

Science.gov (United States)

Pierson, David J

2014-08-01

Because of the importance of his original contributions and their practical relevance today, Thomas L Petty (1932-2009) was arguably the most important physician in the history of respiratory care. As much as any single individual, he was responsible for the concept of intensive and multidisciplinary respiratory care. In the 1960s and 1970s, he made key observations and introduced pioneering therapies in the ICU and in the home. He was the first to describe and name ARDS and to show how to use PEEP to treat life-threatening hypoxemia. He was one of the first anywhere to organize a pulmonary rehabilitation program and to show the beneficial effects of long-term oxygen therapy in COPD. Dr Petty emphasized the importance of practical, hands-on respiratory care education for both physicians and non-physicians using a collaborative team approach. He targeted educational activities and practical resources specifically to patients, and he showed how researchers and clinicians could interact responsibly with innovators in industry to the benefit of both. His life and career provide 6 important lessons for respiratory clinicians today and in the future: (1) whatever their roles, RTs and other clinicians in this field need to be experts in its core areas, such as mechanical ventilation, ARDS, and COPD; (2) respiratory care is a team activity: every member is important, and all the members need to communicate well and work together; (3) education needs to be targeted to those in the best position to benefit the patient, including primary care providers and family members; (4) everyone in the field needs to understand the important role of the respiratory care industry and to deal with it responsibly; (5) it must never be forgotten that it is all about the patient; and (6) respiratory care should be exciting and fun.

The present study investigates the structure of lycopene aggregates both in vitro and in vivo using ultraviolet-visible (UV-vis) and Raman spectroscopies. The electronic absorption bands of the J- and H-aggregates in vitro shift to lower and higher energies, respectively, compared to that of the lycopene monomer. Along with these results, the frequencies of the ν 1 Raman bands were shifted to lower and higher frequencies, respectively. By plotting the frequencies of the ν 1 Raman band against the S 0 → S 2 transition energy, a linear relationship between the data set with different aggregation conformations can be obtained. Therefore, the band positions depending on the different conformations can be explained based on the idea that the effective conjugated C═C chain lengths within lycopene molecules are different due to the environmental effect (site-shift effect) caused by the aggregation conformation. Applying this knowledge to the in vivo measurement of a tomato fruit sample, the relationship between the aggregation conformation of lycopene and the spectral patterns observed in the UV-vis as well as Raman spectra in different parts of tomato fruits was discussed in detail. The results showed that the concentration of lycopene (particularly that of the J-aggregate) specifically increased, whereas that of chlorophyll decreased, with ripening. Furthermore, Raman imaging indicated that lycopene with different aggregate conformations was distributed inhomogeneously, even within one sample. The layer formation in tomato tissues with high concentrations of J- and H-aggregates was successfully visualized. In this manner, the presence of lycopene distributions with different aggregate conformations was unveiled in vivo.

Review of primary spaceflight-induced and secondary reloading-induced changes in slow antigravity muscles of rats

Science.gov (United States)

Riley, D. A.

We have examined the light and electron microscopic properties of hindlimb muscles of rats flown in space for 1-2 weeks on Cosmos biosatellite flights 1887 and 2044 and Space Shuttle missions Spacelab-3, Spacelab Life Sciences-1 and Spacelab Life Sciences-2. Tissues were obtained both inflight and postflight permitting definition of primary microgravity-induced changes and secondary reentry and gravity reloading-induced alterations. Spaceflight causes atrophy and expression of fast fiber characteristics in slow antigravity muscles. The stresses of reentry and reloading reveal that atrophic muscles show increased susceptibility to interstitial edema and ischemic-anoxic necrosis as well as muscle fiber tearing with disruption of contractile proteins. These results demonstrate that the effects of spaceflight on skeletal muscle are multifaceted, and major changes occur both inflight and following return to Earth's gravity.

A complete census of all the biogas plants operating or under construction today in Italy has been carried out. This shows that more than 60 full-scale plants treating animal wastes are today in operation. Then there are several pilot and experimental plants built by the numerous Italian firms that design and sell anaerobic digesters and by various research groups of the universities and of state agencies. Some plants, among which some large-size ones, have been self-built by the farmers. The great amount of collected data allowed us to focus the main technological choices regarding materials, mixing and heating systems, technological cycles and to confront them with the performance of the plants and with the principal technical issues and the problems of management that can be found on large scale plants. Then the analysis of daily biogas production allowed us to determine real parameters of specific production for various kinds of animal wastes and animal farms. Other interesting data concern the main technological means used to transform the biogas into energy: in Italy, for the presence of Flat Industries that produce the TOTEM, the prevalent choice is toward cogeneration of electricity and heat. Anyway there are interesting examples of utilization of biogas for drying forages, for steam generation in cheese factories, and compressed, as a fuel for farm tractors and cars. A complete photographic documentation of all the plants enclosed in the census is also available. 3 refs., 1 fig., 23 tabs.

At the Miyazaki test track today, the new test vehicle, MLU002N, is under test run to obtain necessary data for Yamanashi test track where the construction is underway, the test vehicle has been ordered and the first tunnel was completed in December 1993. Superconducting magnetohydrodynamic drive ship, MHDS, 'Yamato 1' has completed its experiment in 1992 and it is now under preparation to exhibit to the public in___1994. Furthermore, to promote the research development of MHDS, the detailed discussion is underway on the magnetohydrodynamic drive equipment as well as the research on the future scheme. Neither an automobile nor railway but a new transport system called EQUOS LIM CAR(ELC) has been proposed. By using the rotating magnetic field, it will levitate on the aluminum like reaction plate. On the normal road, it will run by rolling the wheels like an electric car but on the highway, it will levitate on the guideway resulting to less noise, less vibration and pollution free drive. To understand the concept of the ELC, the model was built and experimented by using permanent magnet. The same model was donated to the MUSEUM OF SCIENCE AND INDUSTRY in Chicago and was displayed to the public. Today, the trial superconducting magnet has been made and the research development of the subsystem is underway. Research development of superconducting elevator, equipment for the launching of spaceship, tube transportation system and others are in progress for the superconducting applied transportation system.

How today's USM diagnostics solve metering problems[Ultrasonic meters

Energy Technology Data Exchange (ETDEWEB)

Lansing, John

2005-07-01

This paper discusses both basic and advanced diagnostic features of gas ultrasonic meters (USM), and how capabilities built into today's electronics can identify problems that often may not have been identified in the past. It primarily discusses fiscal-quality, multi-path USMs and does not cover issues that may be different with non-fiscal meters. Although USMs basically work the same, the diagnostics for each manufacturer does vary. All brands provide basic features as discussed in AGA 9. However, some provide advanced features that can be used to help identify issues such as blocked flow conditioners and gas compositional errors. This paper is based upon the Daniel USM design and the information presented here may or may not be applicable to other manufacturers. (author) (tk)

The power of data: structural bioinformatics yesterday and today

KAUST Repository

Tramontano, Anna

2016-01-25

The protein structure database was established in 1971. At the time it contained seven structures, today there are more than 100,000. The improvement is not only a matter of quantity, but also of quality. Did we effectively exploit this information to gain knowledge? The answer is certainly affirmative. I will illustrate how this wealth of experimental data has allowed us to explore the landscape of macromolecular structures on one side, and to uncover the properties of specific protein families on the other. The latter plays an essential role in pursuing exciting new avenues in biomedical and biotechnological sciences. Experimental data are also part of a virtuous cycle whereby they reinforce and guide our ability to infer unknown macromolecular structures, which, while providing relevant information to scientists, permits to gauge the level of our understanding of the complex problem of protein folding. A paradigmatic example of the latter is represented by the “Critical Assessment of Techniques for Protein Structure Prediction” (CASP) initiative that I will briefly discuss.

Little is known about reproductive function in girls with youth-onset type 2 diabetes. To characterize girls with irregular menses, and effects of glycemic treatments on menses and sex steroids in the Treatment Options for Type 2 Diabetes in Youth (TODAY) study. Differences in demographic, metabolic, and hormonal characteristics between regular vs. irregular menses groups were tested; treatment group (metformin +/- rosiglitazone, metformin + lifestyle) effect on menses and sex steroids over time in the study was assessed. This is a secondary analysis of TODAY data. Multi-center study in an academic setting. TODAY girls not on hormonal contraception and those > 1-year post-menarche were included. Irregular menses was defined as irregular menses. Those with irregular vs. regular menses had higher body mass index (BMI) (p=0.001), AST (p=0.001), free androgen index (p=0.0003), total testosterone (p=0.01); and lower sex-hormone binding globulin (SHBG) (p=0.004) and estradiol (p=0.01). Differences remained after adjusting for BMI. There was no treatment group effect on menses or sex steroids at 12 or 24 months, and no association of sex steroids with measures of insulin sensitivity or secretion. Menstrual dysfunction is common in girls with recently diagnosed T2D and associated with alterations in sex steroids, SHBG, and AST, but not with alteration in insulin sensitivity or β-cell function, and did not improve with 2 years of anti-hyperglycemic treatment.

Big Data, the perfect instrument to study today's consumer behavior

Full Text Available Consumer behavior study is a new, interdisciplinary and emerging science, developed in the 1960s. Its main sources of information come from economics, psychology, sociology, anthropology and artificial intelligence. If a century ago, most people were living in small towns, with limited possibilities to leave their community, and few ways to satisfy their needs, now, due to the accelerated evolution of technology and the radical change of life style, consumers begin to have increasingly diverse needs. At the same time the instruments used to study their behavior have evolved, and today databases are included in consumer behavior research. Throughout time many models were developed, first in order to analyze, and later in order to predict the consumer behavior. As a result, the concept of Big Data developed, and by applying it now, companies are trying to understand and predict the behavior of their consumers.

Human computer interaction (HCI) equates nurses using voice assisted technology within a clinical setting to document patient care real time, retrieve patient information from care plans, and complete routine tasks. This is a reality currently utilized by clinicians today in acute and long term care settings. Voice assisted documentation provides hands & eyes free accurate documentation while enabling effective communication and task management. The speech technology increases the accuracy of documentation, while interfacing directly into the electronic health record (EHR). Using technology consisting of a light weight headset and small fist size wireless computer, verbal responses to easy to follow cues are converted into a database systems allowing staff to obtain individualized care status reports on demand. To further assist staff in their daily process, this innovative technology allows staff to send and receive pages as needed. This paper will discuss how leading edge and award winning technology is being integrated within the United States. Collaborative efforts between clinicians and analyst will be discussed reflecting the interactive design and build functionality. Features such as the system's voice responses and directed cues will be shared and how easily data can be documented, viewed and retrieved. Outcome data will be presented on how the technology impacted organization's quality outcomes, financial reimbursement, and employee's level of satisfaction.

Post-mastectomy breast reconstruction with expanders and implants is recognized as an integral part of breast cancer treatment. Its main complication is represented by capsular contracture, which leads to poor expansion, breast deformation, and pain, often requiring additional surgery. In such a scenario, the debate continues as to whether the second stage of breast reconstruction should be performed before or after post-mastectomy radiation therapy, in light of potential alterations induced by irradiation to silicone biomaterial. This work provides a novel, multi-technique approach to unveil the role of radiotherapy in biomaterial alterations, with potential involvement in capsular contracture. Following irradiation, implant shells underwent mechanical, chemical, and microstructural evaluation by means of tensile testing, Attenuated Total Reflectance Fourier Transform InfraRed spectroscopy (ATR/FTIR), Scanning Electron Microscopy (SEM), high resolution stylus profilometry, and Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS). Our findings are consistent with radiation-induced modifications of silicone that, although not detectable at the microscale, can be evidenced by more sophisticated nanoscale surface analyses. In light of these results, biomaterial irradiation cannot be ruled out as one of the possible co-factors underlying capsular contracture. - Highlights: • The debate continues whether to perform breast reconstruction before or after PMRT. • Radiation therapy may alter implant material, concurring to capsular contracture. • In this work, irradiated implants were investigated by a multi-technique approach. • Radiation-induced alterations could be evidenced by ATR/FTIR and ToF-SIMS. • Reported alteration might represent a co-factor underlying capsular contracture.

Today, you are about as safe in a U.S. hospital as you would be parachuting off a bridge or a building. But it doesn't have to be that way. Right now, some hospitals are making enormous short-term improvements, with no legislation or market reconfiguration and little or no capital investment. Instead of waiting for sweeping changes in market mechanisms, these institutions are taking an operations approach to patient care. In case after detailed case, the article describes how doctors, nurses, technicians, and managers are radically increasing the effectiveness of patient care and dramatically lowering its cost by applying the same capabilities in operations design and improvement that drive the famous Toyota Production System. They are removing ambiguity in the output, responsibilities, connections, and methods of their work processes. These changes-which can be done in the course of an ordinary workday, sometimes in a matter of hours-are designed to make the following crystal clear: Which patient gets which procedure (output); Who does which aspect of the job (responsibility); Exactly which signals are used to indicate that the work should begin (connection); and Precisely how each step is carried out (method). Equally important, managers are being transformed from rescuers who arrive with ready-made solutions into problem solvers who help colleagues learn the experimental method. Thus, these hospitals are breaking free of the work-around culture that routinely obscures the root causes of so many problems, creates so much waste, and leads to so many unnecessary deaths.

Teenage Mothers Today: What We Know and How It Matters

Science.gov (United States)

Mollborn, Stefanie

2016-01-01

Over the past two decades, births to U.S. teenagers have fallen and no longer follow overall fertility patterns. Yet the unique challenges faced by teenage mothers and their families justify continued research. Across disciplines, newer work has furthered our understanding of teenage motherhood today. In this article, I highlight four areas of progress: processes of selection into teenage motherhood, the broader consequences of teenage childbearing beyond the socioeconomic realm, heterogeneity of effects, and the application of life course principles. Emerging societal trends such as complex family structures, a stalled recovery from the recession for families of low socioeconomic status, and a rapidly evolving political environment for reproductive health care continue to challenge the lives of teenage mothers. Given that the consequences for teenagers of becoming mothers may change, continued research is needed. Shifts in policy to favor supporting teenage mothers and addressing the causes of both teenage pregnancy and social disadvantage may help improve the lives of these mothers and their families.

Full Text Available Christian theologians give many different interpretations to the Scriptures, particularly with regard to their ethical perspectives and their application to the present. An examination and criticism of various approaches adopted at present to the ethical dimension of the Scriptures is undertaken. A distinction is made between the revealed and lasting message of the Scriptitres and the message that is conditioned by culture and hence subject to change. Using the thought of Ricoeur and Hauerwas an approach is presented which attempts to do justice to the twofold polarity of the worid of the Bible and the world of today. In order to preserve a scenario of concreteness, attention is given to one practical example, namely the issue of homosexuality. After investigating the Scriptural approach to this question, an attempt is made to see how this issue can be viewed from a Christian perspective in the context of the present world.

Crosscheck Principle in Pediatric Audiology Today: A 40-Year Perspective.

Science.gov (United States)

Hall, James W

2016-09-01

The crosscheck principle is just as important in pediatric audiology as it was when first described 40 years ago. That is, no auditory test result should be accepted and used in the diagnosis of hearing loss until it is confirmed or crosschecked by one or more independent measures. Exclusive reliance on only one or two tests, even objective auditory measures, may result in a auditory diagnosis that is not clear or perhaps incorrect. On the other hand, close and careful analysis of findings for a test battery consisting of objective procedures and behavioral tests whenever feasible usually leads to prompt and accurate diagnosis of auditory dysfunction. This paper provides a concise review of the crosscheck principle from its introduction to its clinical application today. The review concludes with a description of a modern test battery for pediatric hearing assessment that supplements traditional behavioral tests with a variety of independent objective procedures including aural immittance measures, otoacoustic emissions, and auditory evoked responses.

Geller, Harold A.

2014-01-01

I will discuss my research into the issues associated with the nature of any extraterrestrials that may be encountered in the future in our galaxy. This research was sparked by statements made by Stephen Hawking in 2010 regarding his fear of emitting radiation from our Earth so that an extraterrestrial intelligent civilization may be alerted to our existence in the galaxy today. While addressing issues of extraterrestrial altruism, a probabilistic equation was developed which addresses the number of extraterrestrial intelligent life forms that may exist in our galaxy today, who could use our bodies for nourishment or reproductive purposes. The equation begins with the results from a Drake Equation calculation, and proceeds by addressing such biochemical parameters as the fraction of ETIs with: dextro sugar stereo-isomers; levo amino acid stereo-isomers; similar codon interpretation; chromosomal length and, similar cell membrane structure to allow egg penetration.

International Nuclear Information System (INIS)

Berge, P.

1998-01-01

Water chemistry has always been, from the very beginning of operation of power Pressurized Water Reactors (PWRs), an important factor in determining the integrity of many reactor components. For both the primary and secondary coolant circuits, the parameters to control the quality of the chemistry have been subject to changes in time. These changes were dictated mainly by corrosion problems which required an adjustment of the chemistry, before any modification could be made in the design or the selection of materials for the subsequently built reactors or replacement components. The situation today, despite 40 years of experience, still leaves open different options for the specifications of the chemistry of the circuits. These options are sometimes due to differences in design or materials of the circuits, but more often, to the perception by the plant chemists, of the role of the chemistry on the different phenomena which could affect the operation of their plant. Paul Cohen, who was well known in the nuclear industry for the early development of the chemistry in PWRs in the USA, used to say, 'if the head chemist has changed in a plant, the chemistry will change'. The purpose of this lecture is to discuss some of the options which are offered to the chemist in compliance with the basic principles of the chemistry guidelines. (J.P.N.)

At the end of the 19th century, the Society for the Prevention of Cruelty to Children was founded in New York, after a barbarous case of neglect and abuse of a girl became public. From then on, children received more and more protection. Only in the 1950s were doctors in the USA bound by law to report cases of putative physical abuse to officials. In Sweden, physical punishment of children has been forbidden since 1989, and in Germany since 2001. The existence of sexual abuse of children had been a taboo subject for centuries, even though individual attempts to break that taboo were made--e. g., by S. Freud in the theory of seduction (Verführungstheorie). Only with the birth of the women's liberation movement in the early 1970s has public awareness arisen. Due to the work of J. Bowlby in the 1950s, it became clear that children of primates need more than air, water and food, namely a relationship between the child and an adult person (attachment). To what degree the basic needs of children are being fulfilled in Western societies today is still a controversial issue.

This study examined parental factors associated with outcomes of youth in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial. Of 699 youth with type 2 diabetes in the TODAY cohort, 623 (89.1%) had a parent participate and provide data at baseline, including weight, HbA1c, blood pressure, symptoms of depression, binge eating (BE), and medical history. Youth were followed 2-6.5 years. Data were analyzed using regression models and survival curve methods. Parental diabetes (43.6% of parents) was associated with higher baseline HbA1c (P parent, P = 0.0002). Parental hypertension (40.6% of parents) was associated with hypertension in youth during TODAY (40.4% vs. 27.4% of youth with and without parental hypertension had hypertension, P = 0.0008) and with higher youth baseline BMI z scores (P = 0.0038). Parents had a mean baseline BMI of 33.6 kg/m(2). Parental obesity (BMI >30 kg/m(2)) was associated with higher baseline BMI z scores in the youth (P parents (20.6% of parents) were related to youth depressive symptoms at baseline only (P = 0.0430); subclinical BE in parents was related to the presence of subclinical BE (P = 0.0354) and depressive symptoms (P = 0.0326) in youth throughout the study period. Parental diabetes and hypertension were associated with lack of glycemic control, hypertension, and higher BMI z scores in youth. Further research is needed to better understand and address parental biological and behavioral factors to improve youth health outcomes. © 2015 by the American Diabetes Association.

Full Text Available Humankind is diverse, and religious humankind especially so. Different languages, faiths, customs, views, thoughts and opinions are all to be considered when one wants to talk about neighbourhood and neighbourliness today. Indeed, what do neighbourhood and neighbourliness mean, and what it means to live in neighbourhood with others in the period labelled as globalization? My paper discusses the modern day affirmation of the idea of neighbourhood among Muslims, Christians and Jews. I consider that task most important, since symbols, ideas, and religious representations of Muslims, Christians and Jews have been somehow a part of neighbourhood and neighbourliness for a very long time. How can we preserve a neighbourhood and neighbourliness? How can we extract a neighbourhood of human lives and fates from a neighbourhood of symbols, representations and ideas? This paper will try to give answers to these questions.

The Caries Phenomenon: A Timeline from Witchcraft and Superstition to Opinions of the 1500s to Today's Science

Directory of Open Access Journals (Sweden)

John D. Ruby

2010-01-01

Full Text Available This historical treatise follows the documented timeline of tooth decay into today's understanding, treatment, and teaching of caries biology. Caries has been attributed to many different causes for several millennia, however, only since the late 1900s has research revealed its complex multifactorial nature. European writers of the 1600s to 1700s held views that general health, mechanical injuries, trauma, and sudden temperature changes all caused caries—holding a common belief that decay was due to chemical agents, faulty saliva, and food particles. Until the early 1800s most writers believed that caries was due to inflammation from surrounding diseased alveolar bone. Today's science has demonstrated that caries is caused by indigenous oral microorganisms becoming a dynamic biofilm, that in the presence of fermentable sugars produce organic acids capable of dissolving inorganic enamel and dentin followed by the proteolytic destruction of collagen leaving soft infected dentin. As bacteria enter the pulp, infection follows.

Reference service remains a core function of modern libraries. However, how and where we provide assistance has evolved with changing technologies and the shifting habits and preferences of our users. One way libraries can provide the on-demand, in-person assistance while managing and developing new services and resources that will benefit current and future users is to reconsider how their reference points and services are staffed and adopt a staff-based reference model.

Spacelab Life Sciences flight experiments: an integrated approach to the study of cardiovascular deconditioning and orthostatic hypotension

Science.gov (United States)

Gaffney, F. A.

1987-01-01

The microgravity environment of spaceflight produces rapid cardiovascular changes which are adaptive and appropriate in that setting, but are associated with significant deconditioning and orthostatic hypotension on return to Earth's gravity. The rapidity with which these space flight induced changes appear and disappear provides an ideal model for studying the underlying pathophysiological mechanisms of deconditioning and orthostatic hypotension, regardless of etiology. Since significant deconditioning is seen after flights of very short duration, muscle atrophy due to inactivity plays, at most, a small role. These changes in circulatory control associated with cephalad fluid shifts, rather than inactivity per se, are probably more important factors. In order to test this hypothesis in a systematic way, a multidisciplinary approach which defines and integrates inputs and responses from a wide variety of circulatory sub-systems is required. The cardiovascular experiments selected for Spacelab Life Sciences flights 1 and 2 provide such an approach. Both human and animal models will be utilized. Pre- and post-flight characterization of the payload crew includes determination of maximal exercise capacity (bicycle ergometry), orthostatic tolerance (lower body negative pressure), alpha and beta adrenergic sensitivity (isoproterenol and phenylephrine infusions), baroreflex sensitivity (ECG-gated, stepwise changes in carotid artery transmural pressure with a pneumatic neck collar), and responses to a 24 h period of 5 deg head-down tilt. Measurements of cardiac output (CO2 and C2H2 rebreathing), cardiac chamber dimensions (phased-array 2-dimensional echocardiography), direct central venous pressure, leg volume (Thornton sock), limb blood flow and venous compliance (occlusion plethysmography), blood and plasma volumes, renal plasma flow and glomerular filtration rates, and various hormonal levels including catecholamines and atrial natriuretic factor will also be obtained

Manganese oxidation is an important biogeochemical process that is largely regulated by bacteria through enzymatic reactions. However, the detailed mechanism is poorly understood due to challenges in isolating and characterizing these unknown enzymes. A manganese oxidase, Mnx, from Bacillus sp. PL-12 has been successfully overexpressed in active form as a protein complex with a molecular mass of 211 kDa. We have recently used surface induced dissociation (SID) and ion mobility-mass spectrometry (IM-MS) to release and detect folded subcomplexes for determining subunit connectivity and quaternary structure. The data from the native mass spectrometry experiments led to a plausible structural model of this multicopper oxidase, which has been difficult to study by conventional structural biology methods. It was also revealed that each Mnx subunit binds a variable number of copper ions. Becasue of the heterogeneity of the protein and limited mass resolution, ambiguities in assigning some of the observed peaks remained as a barrier to fully understanding the role of metals and potential unknown ligands in Mnx. In this study, we performed SID in a modified Fourier transform-ion cyclotron resonance (FTICR) mass spectrometer. The high mass accuracy and resolution offered by FTICR unveiled unexpected artificial modifications on the protein that had been previously thought to be iron bound species based on lower resolution spectra. Additionally, isotopically resolved spectra of the released subcomplexes revealed the metal binding stoichiometry at different structural levels. This method holds great potential for in-depth characterization of metalloproteins and protein-ligand complexes. [Figure not available: see fulltext.

Interfaith education: A new model for today's interfaith families

Science.gov (United States)

Gordon, Sheila C.; Arenstein, Benjamin

2017-04-01

With societal changes rapidly transforming cultures that had been largely homogenous, today's multi-cultural - and in particular interfaith - families need new educational strategies to help them understand their cultural roots and identify and clarify what aspects of their heritages they wish to nurture and transmit to their children. This paper focuses on a new model for religious education, namely non-doctrinaire "dual-faith" education, which the principal author has helped to develop in the United States (US) through the Interfaith Community (IFC), a small, independent non-profit organisation created and led by dual-faith Jewish/Christian families. The model is premised on the notion that families can have two different faiths in one household and that - with respect and education - families can be harmonious, religion can be transmitted, and tolerance broadly nurtured. While the model is particular to the US and to families with Jewish and Christian heritages, its premises and structure have significant potential to be adaptable to other religious combinations and other cultures and countries. After reviewing relevant literature and situating the IFC model in the global and US contexts, the paper sets out to clarify the importance of the concept, describe its elements, and discuss its implications for religious education in this time of changing ethos and demography.

"What Today's University Students Have Taught Us”

Alison J. Head

2016-12-01

Full Text Available Today, more students in the US are attending university than ever before. An unprecedented number of these students were born digital—meaning digital technologies have been a constant feature in their lives. For these young adults, information literacy competencies are always being formed, practiced, and learned. Project Information Literacy (PIL is a series of ongoing quantitative and qualitative research studies in the US that investigates what it is like to be a university student in the digital age. This research study has investigated how students find information and conduct research—in their words and through their experiences—for coursework, use in their everyday lives, and, once they graduate, in the workplace and their communities. Since 2008, more than 11,000 university students at nearly 60 US higher education institutions have been surveyed or interviewed, making PIL the largest study of information literacy ever conducted. Results from PIL’s studies have concluded students’ information competencies are put to the test in the vast information landscape they inhabit. Furthermore, finding and using information is exponentially more complex than it was a generation ago, especially since the information landscape has shifted from one of scarce resources to one of overload. In this keynote, five research takeaways were presented from PIL’s eight studies: (1 Students find research more difficult than ever before, (2 getting started is the hardest part of research, (3 frustrations begin with finding context, i.e., big picture, information-gathering, language, and situational context, (4 search strategies are based on predictability, familiarity, and efficiency, and (5 evaluation is the one information skills most learn to use. Discussion included implications of these findings for teaching, learning, work, and librarianship in the 21st century.

Lupus imposes a substantial burden on patients; however, little is known about its impact on those caring for patients with the disease. In this study, we examined the impact 'caring for patients with lupus' has on caregivers from their own perspective. UNVEIL was a one-time online national cross-sectional survey developed in partnership with the Lupus Foundation of America and fielded targeting the US Lupus Foundation of America constituents in 2014. Eligible caregivers were adults who self-identified as unpaid caregivers of patients with lupus. Eligible caregivers had to complete a series of sociodemographic questions as well as a series of well established outcome measures, such as the Short Form 12v2 Health Survey, the Work Productivity and Activity Index, the Caregiver Burden Inventory, and the Perceived Benefits of Caregiving Scale. A total of 253 caregivers completed the survey. The majority of caregivers (90.1%) were aged 60 years or younger, more than half (54.2%) were men, and more than half (59.7%) identified themselves as either a spouse or a partner to the patient with lupus they were caring for. Overall health-related quality of life was close to the norm mean of the general US population. Caregivers who were employed missed an average of 12.8% of paid work time due to caregiving responsibilities and reported a 33.5% reduction in on-the-job effectiveness. Nearly half of the caregivers surveyed (49.4%) indicated that their caregiving responsibilities impacted their ability to socialize with friends, and almost all caregivers (97.6%) reported experiencing increased anxiety and stress in relation to their caregiving role. Caregiving for patients with lupus has a substantial impact on the work productivity and the social and emotional functioning of caregivers. Healthcare professionals and policymakers should continually assess the impact of healthcare decisions on the well-being of those caring for patients with lupus. © The Author(s) 2016.

The crystal structures of the tryparedoxin-tryparedoxin peroxidase couple unveil the structural determinants of Leishmania detoxification pathway.

Directory of Open Access Journals (Sweden)

Annarita Fiorillo

Full Text Available Leishmaniasis is a neglected disease caused by Leishmania, an intracellular protozoan parasite which possesses a unique thiol metabolism based on trypanothione. Trypanothione is used as a source of electrons by the tryparedoxin/tryparedoxin peroxidase system (TXN/TXNPx to reduce the hydroperoxides produced by macrophages during infection. This detoxification pathway is not only unique to the parasite but is also essential for its survival; therefore, it constitutes a most attractive drug target. Several forms of TXNPx, with very high sequence identity to one another, have been found in Leishmania strains, one of which has been used as a component of a potential anti-leishmanial polyprotein vaccine. The structures of cytosolic TXN and TXNPx from L. major (LmTXN and LmTXNPx offer a unique opportunity to study peroxide reduction in Leishmania parasites at a molecular level, and may provide new tools for multienzyme inhibition-based drug discovery. Structural analyses bring out key structural features to elucidate LmTXN and LmTXNPx function. LmTXN displays an unusual N-terminal α-helix which allows the formation of a stable domain-swapped dimer. In LmTXNPx, crystallized in reducing condition, both the locally unfolded (LU and fully folded (FF conformations, typical of the oxidized and reduced protein respectively, are populated. The structural analysis presented here points to a high flexibility of the loop that includes the peroxidatic cysteine which facilitates Cys52 to form an inter-chain disulfide bond with the resolving cysteine (Cys173, thereby preventing over-oxidation which would inactivate the enzyme. Analysis of the electrostatic surface potentials of both LmTXN and LmTXNPx unveils the structural elements at the basis of functionally relevant interaction between the two proteins. Finally, the structural analysis of TXNPx allows us to identify the position of the epitopes that make the protein antigenic and therefore potentially suitable

The primary payload for Space Shuttle Mission STS-42, launched January 22, 1992, was the International Microgravity Laboratory-1 (IML-1), a pressurized manned Spacelab module. The goal of IML-1 was to explore in depth the complex effects of weightlessness of living organisms and materials processing. Around-the-clock research was performed on the human nervous system's adaptation to low gravity and effects of microgravity on other life forms such as shrimp eggs, lentil seedlings, fruit fly eggs, and bacteria. Materials processing experiments were also conducted, including crystal growth from a variety of substances such as enzymes, mercury iodide, and a virus. The Huntsville Operations Support Center (HOSC) Spacelab Payload Operations Control Center (SL POCC) at the Marshall Space Flight Center (MSFC) was the air/ground communication channel used between the astronauts and ground control teams during the Spacelab missions. Featured are activities of the Organic Crystal Growth Facility (OCGF) and Radiation Monitoring Container Device (RMCD) groups in the SL POCC during the IML-1 mission.

At present radically changed not only nature, but also the very essence of armed violence. Today is not the purpose of aggression capture national wealth and resources, the enslavement of the people or the occupation of foreign lands, and complete submission of the enemy at will. Along with how the purpose of armed violence did not become physical destruction of the enemy, and it complete submission to his will, in future military conflicts, the use of force may not even apply at all or not be the key. If you can impose its will on the opponent, make him willingly follow your interests, then the war aims can be achieved without the use of weapons.

Uzbekistan unveiled

International Nuclear Information System (INIS)

Mazurkevich, A.P.

1993-01-01

Through centuries of revolution, war and strife, the people of Uzbekistan have built a reputation as skilled and tenacious merchants. Since antiquity, when the Silk Road from China turned toward Europe at Smarakand, they have been master traders of such valuable commodities as cotton, fruits, vegetables, spices and gold. Now, they're about to introduce another of their specialties to the world: Uranium. Uranium mining in the country is controlled by a new, independent company, the Kizilkumredmetzoloto, parent of the Navoi Mining ampersand Metallurgy Combine [NMMC]. Established in 1958 at the height of the Cold War, when uranium mining for military stockpiles got started in earnest, Navoi was wholly owned by the USSR's Ministry of Medium Machine Building. Up until 1991, virtually all of Navoi's uranium production, strictly in the form of uranium concentrates, was used for either military purposes or for nuclear power plants within the former Soviet Union. The republic exerted no control over the final destination of its uranium. All production and operating decisions for Navoi's mines were dictated by the Soviet Union's Ministry of Atomic Power ampersand Industry [MAPI], which developed annual quotas for uranium production in each republic of the country. Uranium from the republics was sold to Techsnabexport [Tenex], the distribution and marketing arm of MAPI. Exports to other countries were handled strictly by Tenex

Reports an error in "Is Political Behavior a Viable Coping Strategy to Perceived Organizational Politics? Unveiling the Underlying Resource Dynamics" by Shuhua Sun and Huaizhong Chen ( Journal of Applied Psychology , Advanced Online Publication, May 22, 2017, np). In the article, Table 1 contained a formatting error. Correlation coefficient values in the last four cells of column 6 were misplaced with correlation coefficient values in the last four cells of column 7. All versions of this article have been corrected. (The following abstract of the original article appeared in record 2017-22542-001.) We conduct a theory-driven empirical investigation on whether political behavior, as a coping strategy to perceived organizational politics, creates resource trade-offs in moderating the relationship between perceived organizational politics and task performance. Drawing on conservation of resources theory, we hypothesize that political behavior mitigates the adverse effect of perceived organizational politics on task performance via psychological empowerment, yet exacerbates its adverse effect on task performance via emotional exhaustion. Three-wave multisource data from a sample of 222 employees and their 75 supervisors were collected for hypothesis testing. Findings supported our hypotheses. Our study enhances understandings of the complex resource dynamics of using political behavior to cope with perceived organizational politics and highlights the need to move stress-coping research from a focus on the stress-buffering effect of coping on outcomes to a focus on the underlying competing resource dynamics.

by stellar winds and other processes. This can help "seed" star-forming regions with some of the chemicals found by the GBT and other telescopes. Narrowing in on the problem of how planets form around young stars, David Wilner of the Harvard-Smithsonian Center for Astrophysics presented observations with the SMA that revealed new details of solar systems in the earliest stages of their formation. Wilner and his colleagues studied nine dusty disks surrounding young stars in a region in the constellation Ophiuchus. "These are the most detailed images of such disks made at these wavelengths," Wilner said. The images show the distribution of material on the same size scale as our own Solar System, and indicate that these disks are capable of producing planetary systems. Two of the disks show large central cavities where young planets may already have swept out the material from their neighborhoods. "Before, we knew that such disks have enough material to form solar systems. These new images tell us that material is in the right places to form solar systems. We're getting a tantalizing peek at the very earliest stages of planet formation," said Sean Andrews, a Hubble Fellow at the CfA. All three areas of study are poised for major advances with the impending arrival of powerful new radio-telescope facilities such as the Atacama Large Millimeter/submillimeter Array (ALMA) and the Expanded Very Large Array (EVLA), and new capabilities for the GBT. Studies of protoplanetary disks and young solar systems will benefit greatly from the groundbreaking new capabilities of ALMA, Wilner said. "While we've been able to study a few of these objects so far, ALMA will be able to give us highly-detailed images of many more that we can't study today," he said. Wilner added that ALMA also will likely provide new information on the chemicals in those still-forming planetary systems. The complex motions and chemistry of Brogan's protoclusters of young, massive stars, also will become much

The Nazi Physicians as Leaders in Eugenics and "Euthanasia": Lessons for Today.

Science.gov (United States)

Grodin, Michael A; Miller, Erin L; Kelly, Johnathan I

2018-01-01

This article, in commemoration of the 70th anniversary of the Doctors' Trial at Nuremberg, reflects on the Nazi eugenics and "euthanasia" programs and their relevance for today. The Nazi doctors used eugenic ideals to justify sterilizations, child and adult "euthanasia," and, ultimately, genocide. Contemporary euthanasia has experienced a progression from voluntary to nonvoluntary and from passive to active killing. Modern eugenics has included both positive and negative selective activities. The 70th anniversary of the Doctors' Trial at Nuremberg provides an important opportunity to reflect on the implications of the Nazi eugenics and "euthanasia" programs for contemporary health law, bioethics, and human rights. In this article, we will examine the role that health practitioners played in the promotion and implementation of State-sponsored eugenics and "euthanasia" in Nazi Germany, followed by an exploration of contemporary parallels and debates in modern bioethics. 1 .

[Child vaccination and its representations in Iran today: from Teheran to Hassanabad].

Science.gov (United States)

Kotobi, L D

1995-01-01

The reception of child immunization in Iran today can be explained by the conjunction of several factors. Firstly, the Pasteur Institute of Teheran (established in 1921) initiated the vaccine transfer, while the successive public health policies developed and systematized it. Since the Islamic Revolution, the application of the Expanded Program of Immunization has allowed the Islamic Republic of Iran to reach the fourth world-wide rank for immunisation of child populations. The socio-cultural appropriation of the technique can also be explained by its integration into the popular preventive practices (such as magic and religious rituals) as well as a specific treatment of the collective/individual question. This paper describes some results of a qualitative anthropological research conducted in Teheran and the rural district of Hassanâbâd (near Isfahân) between 1991 and 1992.

New forecasting methodology indicates more disease and earlier mortality ahead for today's younger Americans.

Reither, Eric N; Olshansky, S Jay; Yang, Yang

2011-08-01

Traditional methods of projecting population health statistics, such as estimating future death rates, can give inaccurate results and lead to inferior or even poor policy decisions. A new "three-dimensional" method of forecasting vital health statistics is more accurate because it takes into account the delayed effects of the health risks being accumulated by today's younger generations. Applying this forecasting technique to the US obesity epidemic suggests that future death rates and health care expenditures could be far worse than currently anticipated. We suggest that public policy makers adopt this more robust forecasting tool and redouble efforts to develop and implement effective obesity-related prevention programs and interventions.

Karl Marx and the Study of Media and Culture Today

Directory of Open Access Journals (Sweden)

Christian Fuchs

2014-02-01

Full Text Available The task of this paper discusses the role of Marx in analysing media, communica-tion and culture today. An analysis of three contemporary Cultural Studies works – Lawrence Grossberg’s monograph Cultural Studies in the Future Tense, John Hartley’s monograph Digital Futures for Cultural and Media Studies and Paul Smith’s edited volume The Renewal of Cultural Studies – shows that there is an agreement that the economy needs to be taken more into account by Cultural Studies, but disagreement on which approach should be taken and what the role of Karl Marx’s works shall be. The paper argues that Marx’s labour theory of value is especially important for critically analysing the media, culture and communica-tion. Labour is still a blind spot of the study of culture and the media, although this situation is slowly improving. It is maintained that the turn away from Marx in Cultural and Media Studies was a profound mistake that should be reverted. Only an engagement with Marx can make Cultural and Media Studies topical, politically relevant, practical and critical, in the current times of global crisis and resurgent critique.

Full Text Available This article reflects on a group of theoretical and literary references that we consider useful to an approach to oral narration as a poetic possibility and artistic form in the contemporary cultural scene. To choose these references, all of which are classics in various fields of narrative studies, we considered their possible relevance to debates in empirical contexts where stories are studied and told in Brazil today. We indicate the importance of the concepts of verbal art and performance (Richard Bauman and Paul Zumthor, the relation between narrative and cultural memory (Lyotard and the opening to the emergence of new narratives suggested by Ricoeur, Kearney, Didi-Huberman and Gagnebin in their discussions based on Walter Benjamin’s classic essay “The Storyteller.” The paper concludes by affirming the singularity of the role of oral narration in the mediations required by the complex contemporary cultural web. It seeks to contribute to the valorization of practices such as storytelling, which has a growing presence in Brazilian schools and other cultural spaces, and support the establishment of increasingly higher ethical-aesthetic standards for research in this field.

2008-11-01

Astronomy is enjoying a golden age of fundamental, exciting discoveries. Europe is at the forefront, thanks to 50 years of progress in cooperation. To remain ahead over the next two to three decades, Europe must prioritise and coordinate the investment of its financial and human resources even more closely. The ASTRONET network, backed by the entire European scientific community, supported by the European Commission, and coordinated by the CNRS, today presents its Roadmap for a brilliant future for European astronomy. ESO's European Extremely Large Telescope is ranked as one of two top-priority large ground-based projects. Astronet and the E-ELT ESO PR Photo 43a/08 The E-ELT Europe is a leader in astronomy today, with the world's most successful optical observatory, ESO's Very Large Telescope, and cutting-edge facilities in radio astronomy and in space. In an unprecedented effort demonstrating the potential of European scientific cooperation, all of European astronomy is now joining forces to define the scientific challenges for the future and construct a common plan to address them in a cost-effective manner. In 2007, a top-level Science Vision was prepared to assess the most burning scientific questions over the next quarter century, ranging from dark energy to life on other planets. European astronomy now presents its Infrastructure Roadmap, a comprehensive 20-year plan to coordinate national and community investments to meet these challenges in a cost-effective manner. The Roadmap not only prioritises the necessary new frontline research facilities from radio telescopes to planetary probes, in space and on the ground, but also considers such key issues as existing facilities, human resources, ICT infrastructure, education and outreach, and cost -- of operations as well as construction. This bold new initiative -- ASTRONET -- was created by the major European funding agencies with support from the European Commission and is coordinated by the National Institute

Shen, Xiaobai

2010-01-01

This paper provides an historical survey of the evolution of rice technology in China, from the traditional farming system to genetically modified rice today. Using sociotechnological analytical framework, it analyses rice technology as a socio-technical ensemble - a complex interaction of material and social elements, and discusses the specificity of technology development and its socio-technical outcomes. It points to two imperatives in rice variety development: wholesale transporting agricultural technology and social mechanism to developing countries are likely lead to negative consequences; indigenous innovation including deploying GM technology for seed varietal development and capturing/cultivating local knowledge will provide better solutions.

The ultimately accountable job: leading today's sales organization.

Science.gov (United States)

Colletti, Jerome A; Fiss, Mary S

2006-01-01

In recent years, sales leaders have had to devote considerable time and energy to establishing and maintaining disciplined processes. The thing is, many of them stop there--and they can't afford to, because the business environment has changed. Customers have gained power and gone global, channels have proliferated, more product companies are selling services, and many suppliers have begun providing a single point of contact for customers. Such changes require today's sales leaders to fill various new roles: Company leader. The best sales chiefs actively help formulate and execute company strategy, and they collaborate with all functions of the business to deliver value to customers. Customer champion. Customers want C-level relationships with suppliers in order to understand product strategy, look at offerings in advance, and participate in decisions made about future products--and sales leaders are in the best position to offer that kind of contact. Process guru. Although sales chiefs must look beyond the sales and customer processes they have honed over the past decade, they can't abandon them. The focus on process has become only more important as many organizations have begun bundling products and services to meet important customers' individual needs. Organization architect. Good sales leaders spend a lot of time evaluating and occasionally redesigning the sales organization's structure to ensure that it supports corporate strategy. Often, this involves finding the right balance between specialized and generalized sales roles. Course corrector. Sales leaders must watch the horizon, but they can't take their hands off the levers or forget about the dials. If they do, they might fail to respond when quick adjustments in priorities are needed.

What is the Wymysorys Language for Vilamovians Today? Different Functions, Different Language Altitudes

Directory of Open Access Journals (Sweden)

Tymoteusz Król

2016-12-01

Full Text Available What makes the Wilamowice town so unique is the original language, Wymysorys. Vilamovian was brought to Poland by the settlers from the Western Europe and survived through the historical storms in the region till today. However, due to the after-Second World War suppressions of the German-like speaking community – bans of using the language, population displacement and deportations to the labor camps – the intergenerational knowledge transfer was disrupted. Children for whom the Vilamovian was their first language were being force to “unlearn” the language on the behalf of the dominating Polish. This violent political practice resulted in life-lasting trauma and unbreakable fear of speaking Vilamovian. Their native language was being forgotten by the post-war generations, although it was too late for them to naturally canvass Polish instead. Accordingly, a number of people declaring to do not know Wymysorys use particular words from it, while talking in Polish about traditional Vilamovian clothing, customs and values, deeply associated with Vilamowian identity. Contradictory to the earlier predications that Vilamowian language will die completely by the end of the 20th century, in the being of the second decade of the 21st century the dedicated revitalization program was introduced in the region. The initiative engaged scientists from major Polish universities – the University of Warsaw, Adam Mickiewicz University in Poznań – as well as foreign scholars. Wymysorys was introduced to the curriculum of the local schools and the intergenerational meetings are being held regularly. After some time, the Vilamovians also engaged into the revitalization program, even though there are strong differences in their linguistic bases. Today, the knowledge and use of Vilamowian is vividly growing amongst the young. The language once almost forgotten starts not only to gain back its communicative function, but more and more often takes upon a

Tiptoeing to chromosome tips: facts, promises and perils of today's human telomere biology.

Science.gov (United States)

Fajkus, J; Simícková, M; Maláska, J

2002-04-29

The past decade has witnessed an explosion of knowledge concerning the structure and function of chromosome terminal structures-telomeres. Today's telomere research has advanced from a pure descriptive approach of DNA and protein components to an elementary understanding of telomere metabolism, and now to promising applications in medicine. These applications include 'passive' ones, among which the use of analysis of telomeres and telomerase (a cellular reverse transcriptase that synthesizes telomeres) for cancer diagnostics is the best known. The 'active' applications involve targeted downregulation or upregulation of telomere synthesis, either to mortalize immortal cancer cells, or to rejuvenate mortal somatic cells and tissues for cellular transplantations, respectively. This article reviews the basic data on structure and function of human telomeres and telomerase, as well as both passive and active applications of human telomere biology.

Systems biology and genome-wide approaches to unveil the molecular players involved in the pre-germinative metabolism: implications on seed technology traits.

Macovei, Anca; Pagano, Andrea; Leonetti, Paola; Carbonera, Daniela; Balestrazzi, Alma; Araújo, Susana S

2017-05-01

The pre-germinative metabolism is among the most fascinating aspects of seed biology. The early seed germination phase, or pre-germination, is characterized by rapid water uptake (imbibition), which directs a series of dynamic biochemical events. Among those are enzyme activation, DNA damage and repair, and use of reserve storage compounds, such as lipids, carbohydrates and proteins. Industrial seedling production and intensive agricultural production systems require seed stocks with high rate of synchronized germination and low dormancy. Consequently, seed dormancy, a quantitative trait related to the activation of the pre-germinative metabolism, is probably the most studied seed trait in model species and crops. Single omics, systems biology, QTLs and GWAS mapping approaches have unveiled a list of molecules and regulatory mechanisms acting at transcriptional, post-transcriptional and post-translational levels. Most of the identified candidate genes encode for regulatory proteins targeting ROS, phytohormone and primary metabolisms, corroborating the data obtained from simple molecular biology approaches. Emerging evidences show that epigenetic regulation plays a crucial role in the regulation of these mentioned processes, constituting a still unexploited strategy to modulate seed traits. The present review will provide an up-date of the current knowledge on seed pre-germinative metabolism, gathering the most relevant results from physiological, genetics, and omics studies conducted in model and crop plants. The effects exerted by the biotic and abiotic stresses and priming are also addressed. The possible implications derived from the modulation of pre-germinative metabolism will be discussed from the point of view of seed quality and technology.

This article traces the history of leprosy in Reunion from the early eighteenth century, which long paralleled the slave trace. Lepers were confined to a lazaretto and treated with herbs. Father Raimbault, "doctor" and chaplain of the lepers in the middle of the twentieth century, is still honored today. The improvement in living standards and the use of sulfones finally resulted in the control of leprosy. Nonetheless, from 2005 to 2011, an average of three new cases per year were detected among a population of 800,000 inhabitants.

Sustainable power and scenic beauty: The Niagara River Water Diversion Treaty and its relevance today

International Nuclear Information System (INIS)

Sedoff, Andrei; Schott, Stephan; Karney, Bryan

2014-01-01

Niagara Falls and the Niagara River have always attracted great public interest due to their natural beauty, their enormous potential for electricity generation, their recreational value and as an important ecosystem. There have been simultaneous efforts to preserve this unique natural wonder and harness its power through hydroelectric development projects by both the United States and Canada. This paper explores the evolution of these efforts that culminated with the signing of the 1950 Niagara River Water Diversion Treaty that established minimum water flow rates to protect the “scenic beauty” of the falls, allowing the remaining water to be diverted for power production. We examine the rationale that led to specific water flow restrictions and question to what extent they are relevant today, as water intake capacity on the Canadian side has just been extended by around 25%. We find that current restrictions under the Niagara River Water Treaty (that expired in 2000) are not based on sound scientific evidence and estimate the upper limit of potential foregone benefits from clean electricity generation and greenhouse gas reductions. We identify a number of important issues that emerged in the last decades and that would justify an exploration of new treaty rules. - Highlights: • We examine the history of water diversion at Niagara Falls. • We examine the rationale that led to water flow restrictions over Niagara Falls and its relevance today. • We estimate the opportunity cost of foregone energy generation with the new Canadian intake capacity. • Water flow stipulations were not based on the sound scientific or ecosystem analysis. • A renegotiation of the 1950 Niagara River Water Diversion Treaty is overdue

The Culture of Unity and Some of the Great Challenges of Humankind Today

Cepedano Jesús Morán

2016-12-01

Full Text Available This text explores some of the great challenges present in the cultural landscape of today, such as globalization and its associated phenomena – (internationalisation and ultra-contemporaneousness; exasperated economism with its outcome in the scrap culture; the “piecemeal third world war”, according to Pope Francis’ effective expression, which is connected with a widespread and still poorly understood post-humanism and transhumanism; nihilism and the eclipse of religion as an institution. It considers the light that might be shed by the culture arising from the Focolare’s charism of unity, in order to address these challenges rigorously and without hasty demonizing. The overall picture is not intended to be negative but, without being naive, to offer an interpretation that is able to discern the work of the Spirit in the dramatic scenario of present times.

The Epoch of Disk Formation: z is Approximately l to Today

Kassin, Susan; Gardner, Jonathan; Weiner, Ben; Faber, Sandra

2012-01-01

We present data on galaxy kinematics, morphologies, and star-formation rates over 0.1 less than z less than 1.2 for approximately 500 blue galaxies. These data show how systems like our own Milky-Way have come into being. At redshifts around 1, about half the age of the Universe ago, Milky-Way mass galaxies were different beasts than today. They had a significant amount of disturbed motions, disturbed morphologies, shallower potential wells, higher specific star-formation rates, and likely higher gas fractions. Since redshift approximately 1, galaxies have decreased in disturbed motions, increased in rotation velocity and potential well depth, become more well-ordered morphologically, and decreased in specific star-formation rate. We find interrelationships between these measurements. Galaxy kinematics are correlated with morphology and specific star-formation rate such that galaxies with the fastest rotation velocities and the least amounts of disturbed motions have the most well-ordered morphologies and the lowest specific star-formation rates. The converse is true. Moreover, we find that the rate at which galaxies become more well-ordered kinematically (i.e., increased rotation velocity, decreased disturbed motions) and morphologically is directly proportional to their stellar mass.

Undergraduate Biocuration: Developing Tomorrow's Researchers While Mining Today's Data.

Science.gov (United States)

Mitchell, Cassie S; Cates, Ashlyn; Kim, Renaid B; Hollinger, Sabrina K

2015-01-01

Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical "big data" opens the possibility of utilizing biocuration as a means to mine today's data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8-50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week.

Flavonoids possess a rich polypharmacological profile and their biological role is linked to their oxidation state protecting DNA from oxidative stress damage. However, their bioavailability is hampered due to their poor aqueous solubility. This can be surpassed through encapsulation to supramolecular carriers as cyclodextrin (CD). A quercetin- 2HP-β-CD complex has been formerly reported by us. However, once the flavonoid is in its 2HP-β-CD encapsulated state its oxidation potential, its decomplexation mechanism, its potential to protect DNA damage from oxidative stress remained elusive. To unveil this, an array of biophysical techniques was used. The quercetin-2HP-β-CD complex was evaluated through solubility and dissolution experiments, electrochemical and spectroelectrochemical studies (Cyclic Voltammetry) UV-Vis spectroscopy, HPLC-ESI-MS/MS and HPLC-DAD, fluorescence spectroscopy, NMR Spectroscopy, theoretical calculations (density functional theory (DFT)) and biological evaluation of the protection offered against H 2 O 2 -induced DNA damage. Encapsulation of quercetin inside the supramolecule's cavity enhanced its solubility and oxidation profile is retained in its encapsulated state. Although the protective ability of the quercetin-2HP-β-CD complex against H 2 O 2 was diminished, iron serves as a chemical stimulus to dissociate the complex and release quercetin. We found that in a quercetin-2HP-β-CD inclusion complex quercetin retains its oxidation profile similarly to its native state, while iron can operate as a chemical stimulus to release quercetin from its host cavity. The oxidation profile of a natural product once it is encapsulated in a supramolecular cyclodextrin carrier as also it was discovered that decomplexation can be triggered by a chemical stimulus.

Even during the time of Hippocrates, Galen and their colleagues recognized mediastinal affections. However, they were not considered with the surgical treatment. First progress in the treatment options of this severe disease, still denoted as 'terra incognita', over to today's gold standard are pictured. The mediastinitis-registry which was founded by the German Society for Thoracic and Cardiovascular Surgery (DGTHG) in 2011 and the recent establishment of the study group to adopt a guideline 'diagnosis and therapy of postoperative mediastinitis/sternal osteomyelitis following cardiac surgery' are attempts to a standardization of the treatment. Substantial advancement in the treatment of postoperative mediastinitis could be achieved in the past. The mortality dropped as low as less than 10%. With these implementations more benefit for the patients' outcome can be expected.

China's economic expansion and the 'sustainability of sustainability': a Žižekian-Lacanian view

Directory of Open Access Journals (Sweden)

Antonio Gelis Filho

Full Text Available The aim of this paper is to present a Žižekian-Lacanian interpretation of an interesting socio-economic triangle that has so far gained little recognition: the Discourse of Sustainability -Capitalism -China's Economic Expansion. It is sustained here that those three sides are connected and together they build a narrative that is self-perpetuating -at least up to a point. The Lacanian theory of discourse is applied to unveil a less obvious side of that relationship : the discourse of sustainability, as it is presented today is but a discourse of self-indulgence, since most of its versions discuss the possibility of "sustainable consumption", neutralizing the much more powerful discourse of "reducing consumption". China's economic success derives, in that sense from its ability to find a niche as the provider of consumption possibilities for Westerners.

Restocking the optical designers' toolbox for next-generation wearable displays (Presentation Recording)

Three years ago, industry and consumers learned that there was more to Head Mounted Displays (HMDs) than the long-lasting but steady market for defense or the market for gadget video player headsets: the first versions of Smart Glasses were introduced to the public. Since then, most major consumer electronics companies unveiled their own versions of Connected Glasses, Smart Glasses or Smart Eyewear, AR (Augmented Reality) and VR (Virtual Reality) headsets. This rush resulted in the build-up of a formidable zoo of optical technologies, each claiming to be best suited for the task on hand. Today, the question is not so much anymore "will the Smart Glass market happen?" but rather "which optical technologies will be best fitted for the various declinations of the existing wearable display market," one of the main declination being the Smart Glasses market.

Old-fashioned charm and newfangled electronics make today's oil scouts formidable figures

International Nuclear Information System (INIS)

Lorenz, A.

1999-01-01

A profile of oil scouting, a secretive trade within the petroleum industry, was presented. Scouting began as early as 1949 when, in a fiercely competitive industry, a scout had to gain any information anyway he could regarding a competitor's drilling activity. Scouts were particularly useful when the industry was new because it was profitable to pay a field scout to watch a competitor's well from a hilltop with binoculars. If a scout informed their company that a given lease looked promising, the company would snap up that lease and the scout earned his wages many times over. Today's oil scout is more likely to be an independent consultant than a company employee. Their equipment ranges from devices such as parabolic microphones, wireless transmitters, night vision goggles, de-bugging devices, tools for listening through solid objects, and cell phone monitors. Acquired information can be invaluable and can prevent companies from making expensive mistakes, particularly in take-over situations. Estimates range from 100 to 150 independent scouts in Alberta. 2 figs

After mild traumatic brain injury (mTBI), patients have increased long-term mortality rates, persisting even beyond 13 years. Pathophysiology is unclear. Yet, central autonomic network dysfunction may contribute to cardiovascular dysregulation and increased mortality. Purely parasympathetic cardiovascular challenge by eyeball pressure stimulation (EP), might unveil subtle autonomic dysfunction in post-mTBI patients. We investigated whether mild EP shows autonomic cardiovascular dysregulation in post-mTBI patients. In 24 patients (34 ± 12 years; 5-86 months post-injury) and 27 controls (30 ± 11 years), we monitored respiration, electrocardiographic RR intervals (RRI), systolic and diastolic blood pressure (BPsys, BPdia) before and during 2 min of 30 mm Hg EP, applied by an ophthalmologic ocular pressure device (Okulopressor(®)). We calculated spectral powers of RRI in the mainly sympathetic low frequency (LF; 0.04-0.15 Hz) and parasympathetic high frequency (HF; 0.15-0.5 Hz) ranges, and of BP in the sympathetic LF range, the RRI-LF/HF ratio as index of the sympathetic-parasympathetic balance, normalized (nu) RRI-LF- and HF-powers, and LF- and HF-powers after natural logarithmic transformation (ln). Parameters before and during EP in post-mTBI patients and controls were compared by repeated measurement analysis of variance with post hoc analysis (p < 0.05). During EP, BPsys and BPdia increased in post-mTBI patients. Only in controls but not in post-mTBI patients, EP increased RRI-HFnu-powers and decreased RRI-LF-powers, RRI-LFnu-powers, BPsys-LF-powers, BPsys-lnLF-powers and BPdia-lnLF-powers. RRI-LF/HF ratios slightly increased in post-mTBI patients but slightly decreased in controls upon EP. Even with only mild EP, our controls showed normal EP responses and shifted sympathetic-parasympathetic balance towards parasympathetic predominance. In contrast, our post-mTBI patients could not increase parasympathetic heart rate modulation but

Today, the German-lead Cosmic Dust Analyser (CDA) is operated continuously for 10 years in orbit around Saturn. The first discovery of CDA related to Saturn was the measurement of nanometer sized dust particles ejected by to interplanetary space with speeds higher than 100 km/s. Their origin and composition was analysed and and their dynamical studies showed a strong link to the conditions of the solar wind plasma flow. A recent surprising result was, that stream particles stem from the interior of Enceladus. Since 2004 CDA measured millions of dust impacts characterizing the dust environment of Saturn. The instrument showed strong evidence for ice geysers located at the south pole of Saturn's moon Enceladus in 2005. Later, a detailed compositional analysis of the salt-rich water ice grains in Saturn's E ring system lead to the discovery of liquid water below the icy crust connected to an ocean at depth feeding the icy jets. CDA was even capable to derive a spatially resolved compositional profile of the plume during close Enceladus flybys. A determination of the dust-magnetosphere interaction and the discovery of the extended E ring allowed the definition of a dynamical dust model of Saturn's E ring describing the observed properties. The measured dust density profiles in the dense E ring revealed geometric asymmetries.In the final three years CDA performs exogenous and interstellar dust campaigns, studies of the composition and origin of Saturn's main rings by unique ring ejecta measurements, long-duration nano-dust stream observations, high-resolution maps of small moon orbit crossings, studies of the dust cloud around Dione and studies of the E-ring interaction with the large moon Titan.

Some of the biggest challenges facing wildlife today are changes to their environment from both natural and anthropogenic causes. Natural resource managers, planners, policy makers, industry and private landowners must make informed decisions and policies regarding management, conservation, and restoration of species, habitats, and ecosystem function in response to these changes. Specific needs include (1) a better understanding of population status and trends; (2) understanding of species’ habitat needs and roles in supporting ecosystem functions; (3) the ability to assess species’ responses to environmental changes and predict future responses; and (4) the development of innovative techniques and tools to better understand, minimize or prevent any unintended consequences of environmental change.

2011-02-01

Electronic laboratory notebooks are becoming an increasingly popular tool for research and routine laboratories as part of a way to optimize workflow and minimize cost while realizing time-saving benefits. The number and variety of available solutions are quickly increasing; making selection of the right notebook a cumbersome process. To allay some of the strain associated with an exhaustive search through notebook technologies, this paper details some key features from a pool of 35 electronic notebooks available today. This review effectively classifies these notebooks into five categories based on market audience as follows: notebooks suited for a Quality environment can be found within the Quality Assurance/Quality Control pool. Notebooks suited for specialized tasks in Biology or Chemistry can be found within the Biology or Chemistry pools, respectively. Notebooks that are suitable for general science functionalities can be found under either the Research and Development or the Multidiscipline pools. Lastly, notebooks that are designed and developed for the spectrum of stringent Quality laboratories to free-form research laboratories can be found within the Multidiscipline pool. The guidelines put forth in this paper eliminate the need to perform an exhaustive search for a suitable notebook. Copyright © 2011 Society for Laboratory Automation and Screening.

Analytical difficulties facing today's regulatory laboratories: issues in method validation.

Science.gov (United States)

MacNeil, James D

2012-08-01

The challenges facing analytical laboratories today are not unlike those faced in the past, although both the degree of complexity and the rate of change have increased. Challenges such as development and maintenance of expertise, maintenance and up-dating of equipment, and the introduction of new test methods have always been familiar themes for analytical laboratories, but international guidelines for laboratories involved in the import and export testing of food require management of such changes in a context which includes quality assurance, accreditation, and method validation considerations. Decisions as to when a change in a method requires re-validation of the method or on the design of a validation scheme for a complex multi-residue method require a well-considered strategy, based on a current knowledge of international guidance documents and regulatory requirements, as well the laboratory's quality system requirements. Validation demonstrates that a method is 'fit for purpose', so the requirement for validation should be assessed in terms of the intended use of a method and, in the case of change or modification of a method, whether that change or modification may affect a previously validated performance characteristic. In general, method validation involves method scope, calibration-related parameters, method precision, and recovery. Any method change which may affect method scope or any performance parameters will require re-validation. Some typical situations involving change in methods are discussed and a decision process proposed for selection of appropriate validation measures. © 2012 John Wiley & Sons, Ltd.

What are the key characteristics of a Christian life? A comparison of the ethics of Calvin to that of Augustine and their relevance today

Directory of Open Access Journals (Sweden)

J.H. van Wyk

2010-07-01

Full Text Available Augustine and Calvin are two of the greatest (western theologians of all times and it is illuminating and inspiring to investigate what they have to teach as far as Christian life is concerned. Augustine never wrote a work on Christian ethics in the modern sense of the word but from his many writings we can easily deduce what the key characteristics are. He accepted the natural virtues of philosophers (prudence, for- titude, temperance and justice but subordinated them to the “infused virtues” of faith, hope and love. Special attention was also paid to inter alia happiness, humility and truth. Calvin, on the other hand, although following Augustine in many aspects of theology, rejected the virtue ethics of the Greek philosophers and developed a Christological ethics within the broader context of pneumatology. The key characteristics of a Christian life are self-denial, cross-bearing and meditation on the future life – and of course the correct enjoyment of the present life. Although we appreciate much of what the two church fathers have to say, we live in a totally different world context today, facing challenges of far greater proportions, like economical uncertainty, political instability and an immense ecological crisis. Morality is chal- lenged today as never before in world history. Today we have to rethink the relevance of Christian life not only from an individual personal perspective but also in terms of broader social Christian ethics.

CONCLUSIÓN: El develamiento propuesto constituyó una vivencia para que esas personas ostomizadas estén habilitadas para "leer el mundo" y, así, conozcan y caminen rumbo a la transformación de su realidad.OBJECTIVE: To present the critical unveiling of the Itinerary of Freirean Research in the care of people with stoma. METHODS: A qualitative study in health linked to the methodological framework of Freire, which includes obtaining and analysis of data in dialogical circles, comprising three dialectical moments, intertwined in an interdisciplinary manner: thematic research, coding and decoding, and critical unveiling. This occurred in the period between April 2009 and February 2010, with an irregular number of participants, in the auditorium of the President Vargas Specialized Reference Unit, in the city of Belém / PA (Brazil. RESULTS: Inadequate training of health professionals was one of the most relevant topics generated, and unveiled the necessity of implementing a program of continuing education on the care of people with stoma. CONCLUSION: The proposed unveiling constituted a life experience so that these people with stomas were enabled to "read the world" and thus know and walk towards the transformation of their reality.

Surgical management of peptic ulcer disease today--indication, technique and outcome.

Zittel, T T; Jehle, E C; Becker, H D

2000-03-01

The current surgical management of peptic ulcer disease and its outcome have been reviewed. Today, surgery for peptic ulcer disease is largely restricted to the treatment of complications. In peptic ulcer perforation, a conservative treatment trial can be given in selected cases. If laparotomy is necessary, simple closure is sufficient in the large majority of cases, and definitive ulcer surgery to reduce gastric acid secretion is no longer justified in these patients. Laparoscopic surgery for perforated peptic ulcer has failed to prove to be a significant advantage over open surgery. In bleeding peptic ulcers, definitive hemostasis can be achieved by endoscopic treatment in more than 90% of cases. In 1-2% of cases, immediate emergency surgery is necessary. Some ulcers have a high risk of re-bleeding, and early elective surgery might be advisable. Surgical bleeding control can be achieved by direct suture and extraluminal ligation of the gastroduodenal artery or by gastric resection. Benign gastric outlet obstruction can be controlled by endoscopic balloon dilatation in 70% of cases, but gastrojejunostomy or gastric resection are necessary in about 30% of cases. Elective surgery for peptic ulcer disease has been largely abandoned, and bleeding or obstructing ulcers can be managed safely by endoscopic treatment in most cases. However, surgeons will continue to encounter patients with peptic ulcer disease for emergency surgery. Currently, laparoscopic surgery has no proven advantage in peptic ulcer surgery.

Potassium iodide as a thyroid blocker--Three Mile Island to today

Halperin, J.A.

1989-01-01

The Three Mile Island (TMI) nuclear emergency in the U.S. in March 1979 marked the first occasion when use of potassium iodide (KI) was considered for thyroid blocking of the population in the vicinity of a potentially serious release of fission products from a nuclear power reactor. In face of a demand that could not be satisfied by commercial supplies of low-dose KI drug products from the U.S. pharmaceutical industry, the Food and Drug Administration directed the manufacture and stockpiling of sufficient quantities of saturated solution of potassium iodide (SSKI) to provide protection for one million people in the event of a large-scale release of radioiodines. Although the drug was not used, the experience of producing, stockpiling, and making ready for use a large quantity of the drug resulted in significant public policy, regulatory, and logistical issues. A number of these issues have been resolved through scientific debate and consensus, development of official guidance regarding the proper role of KI in nuclear emergencies, and the approval of New Drug Applications for KI products specifically intended for thyroid blocking in nuclear emergencies. Other issues regarding broad-scale implementation of the guidelines remain today. This paper traces the history of the development and implementation of the use of KI from pre-TMI to the present

Silicone oil served as the atmosphere around a rotating steel hemisphere (dotted circle) and an electrostatic field pulled the oil inward to mimic gravity's effects during the experiments. The GFFC thus produced flow patterns that simulated conditions inside the atmospheres of Jupiter and the Sun and other stars. GFFC flew on Spacelab-3 in 1985 and U.S. Microgravity Laboratory-2 in 1995. The principal investigator was John Hart of the University of Colorado at Boulder.

Background For a 2- to 6-year period, interventionists for the TODAY (Treatment Options for type 2 Diabetes in Adolescents and Youth) randomized clinical trial delivered a family-based, behavioral weight-loss program (the TODAY Lifestyle Program) to 234 youth with type 2 diabetes. Interventionists held at least a bachelor's degree in psychology, social work, education, or health-related field and had experience working with children and families, especially from diverse ethnic and socioeconomic backgrounds. This article describes the administrative and organizational structure of the lifestyle program and how the structure facilitated collaboration among study leadership and lifestyle interventionists on the tailoring of the program to best suit the needs of the trial's diverse patient population. Methods During the pilot phase and throughout the duration of the trial, the interventionists' experiences in delivering the intervention were collected in a variety of ways including membership on study committees, survey responses, session audio recordings, and feedback during in-person trainings. Results The experiences of interventionists conveyed to study leadership through these channels resulted in decisions to tailor the lifestyle intervention's delivery location and ways to supplement the standardized educational materials to better address the needs of a diverse patient population. Conclusion The methods used within the TODAY study to encourage and utilize interventionists' experiences while implementing the lifestyle program may be useful to the design of future multi-site, clinical trials seeking to tailor behavioral interventions in a standardized, and culturally and developmentally sensitive manner.

Exploring the role of children's dreams in psychoanalytic practice today: a pilot study.

Lempen, Olivia; Midgley, Nick

2006-01-01

The aim of this research study was to investigate the role of children's dreams in the practice of child psychoanalysis today, and to explore contemporary psychoanalytic understanding of children's dreams. This pilot study consisted of two stages. The first involved a document analysis of published articles in The Psychoanalytic Study of the Child, making a comparison between those of the early 1950s and the 1990s, in order to see in what way the discourse around children's dreams within the psychoanalytic literature has changed over time. The second stage, based on questionnaires and in-depth interviews, attempted to understand in more detail the way contemporary child analysts, working in the Anna Freudian tradition, think about dreams and use them in their clinical practice. Results suggest that there has been a decreased focus on dreams in a clinical context over time, and that this may partly be a consequence of changing theoretical models and changes in training. When work with dreams does take place, it appears that child analysts have

Nurse leaders' perceptions of what compromises successful leadership in today's acute inpatient environment.

Upenieks, Valda

2003-01-01

The purpose of this study was to gain an understanding of nurse leaders' perceptions of both the value of their roles in today's health care setting and their beliefs about how power and gender interface with role worth. Support for the theoretical significance of this research stemmed from Kanter's Structural Theory of Organizational Behavior. Four leaders were recruited at the executive level and 12 at the director/managerial level. The results of the deductive analysis supported Kanter's theory. Eighty-three percent of the nurse leaders validated that access to power, opportunity, information, and resources created an empowered environment, producing a climate that fostered leadership success and enhanced levels of job satisfaction among nurses. This study provided groundwork on the kinds of leadership traits that foster nursing satisfaction and on whether or not gender influences leadership effectiveness. The findings of this study are both timely and relevant for nurse leaders faced with the effects of the current supply-and-demand nursing shortage and with fiscal restraints mandated by managed care and regulatory agencies.

Molecular imaging of small animals has made considerable progress in the last years. Various research fields are interested in imaging small animals due to the lower numbers of animals per experiment. This has advantages with respect to financial, ethical and research aspects. Non-invasive imaging allows examination of one animal several times during the same experiment. This makes it possible to follow a pathological process in the same animal over time. However, the radiological methods used such as magnetic resonance imaging or computed tomography as well as the nuclear medicine methods such as single photon emission computed tomography or positron emission tomography suffer from disadvantages. Molecular aspects are limited in the radiological methods while anatomical localization is difficult in nuclear medicine. The fusion of these methods leads to additional information. This review shows today's possibilities with their advantages as well as disadvantages. (orig.)

The research extends construal theory by testing if a match between the temporal construal framing of a blood donation decision and a blood donation request leads to higher donation intentions than a mismatch. Results show participants considering future donation who read an abstract donation request have significantly higher donation intentions than those who read a concrete request. Conversely, participants considering donating today who read a concrete donation request have significantly higher donation intentions than those who read an abstract request. This study confirms the importance of matching the construal framing of the communication to the temporal framing of the decision.

Full Text Available Streptomyces sp. H-KF8 is an actinobacterial strain isolated from marine sediments of a Chilean Patagonian fjord. Morphological characterization together with antibacterial activity was assessed in various culture media, revealing a carbon-source dependent activity mainly against Gram-positive bacteria (S. aureus and L. monocytogenes. Genome mining of this antibacterial-producing bacterium revealed the presence of 26 biosynthetic gene clusters (BGCs for secondary metabolites, where among them, 81% have low similarities with known BGCs. In addition, a genomic search in Streptomyces sp. H-KF8 unveiled the presence of a wide variety of genetic determinants related to heavy metal resistance (49 genes, oxidative stress (69 genes and antibiotic resistance (97 genes. This study revealed that the marine-derived Streptomyces sp. H-KF8 bacterium has the capability to tolerate a diverse set of heavy metals such as copper, cobalt, mercury, chromate and nickel; as well as the highly toxic tellurite, a feature first time described for Streptomyces. In addition, Streptomyces sp. H-KF8 possesses a major resistance towards oxidative stress, in comparison to the soil reference strain Streptomyces violaceoruber A3(2. Moreover, Streptomyces sp. H-KF8 showed resistance to 88% of the antibiotics tested, indicating overall, a strong response to several abiotic stressors. The combination of these biological traits confirms the metabolic versatility of Streptomyces sp. H-KF8, a genetically well-prepared microorganism with the ability to confront the dynamics of the fjord-unique marine environment.

Vitamin D Deficiency in Europeans Today and in Viking Settlers of Greenland.

Göring, H; Koshuchowa, S

2016-12-01

The vast majority of the Earth's population lives between the 20th and 40th parallel north and south. It seems that right here humans have found the best living conditions relating not only to temperature and food recourses, but also to UV radiation necessary for the production of vitamin D by human skin. An exception to this general rule is Europe. Nearly half a billion people live between the 40th and 60th parallel north of the equator despite the fact that the amounts of UV radiation there are much lower. Moreover, since the time of the Vikings, there has always been a part of the European population that lived even further north than the 60th parallel (the northern parts of Europe, including Greenland). In this work, we present the potential role that vitamin D deficiency might have played in the extinction of the Vikings of Greenland. We analyze factors that contribute to the discrepancy between the theoretical distribution of areas with vitamin D deficiency and today's reality, like the impact of civilization, religious traditions, as well as vitamin D supplementation in food products and as a biologically active dietary additive. The global migration of people on a scale and speed never seen before is now even more important for this discrepancy.

On sociological criteria of religiousness: How many (Orthodox believers are there today?

Full Text Available In this text the author first tries to provide an answer on the number of religious people today in two post-communist and Orthodox countries, and then on the number of Orthodox believers in them. Therefore he analyzes numerous data from empirical evidence using a large number of indicators discussed in the text. The author first analyzes them as indicators of representative dimension of religiousness, then as indicators of beliefs in dogmatic core of Christianity, indicators of current church ritual practice and finally, as indicators of a traditional attitude towards religion and church. With these analyses the author tries to find the criterion or criteria which best express the religiousness of people in a particular area. The analysis identifies three approaches in Russian sociological and religious literature. The first one is defined as a classic, positivistic approach, the second one as post-classic or phenomenological, and the third one as synthetic. Then the author discusses the term attachment to religion and church and its indicators, as well as the indices which are sociologically more suitable for the research of the religious and church complex. In the end the author gives a few methodological instructions for a sociological and empirical research of religiousness.

The Integral Fast Reactor concept: Today's hope for tomorrow's electrical energy needs

Acid rain and the greenhouse effect are getting more attention as their impacts on the environment become evident around the world. Substantial evidence indicates that fossil fuel combustion for electrical energy production activities is a key cause of those problems. A change in electrical energy production policy is essential to a stable, healthy environment. That change is inevitable, it's just a matter of when and at what cost. Vision now, instead of reaction later, both in technological development and public perception, will help to limit the costs of change. The Integral Fast Reactor (IFR) is a visionary concept developed by Argonne National Laboratory that involves electrical energy production through fissioning of heavy metals by fast neutrons in a reactor cooled by liquid sodium. Physical characteristics of the coolant and fuel give the reactor impressive characteristics of inherent and passive safety. Spent fuel is pyrochemically reprocessed and returned to the reactor in the IFR's closed fuel cycle. Advantages in waste management are realized, and the reactor has the potential for breeding, i.e., producing as much or more fuel than it uses. This paper describes the IFR concept and shows how it is today's hope for tomorrow's electrical energy needs. 14 refs., 1 fig., 1 tab

Full Text Available En este artículo veremos de qué manera el descubrimiento del busto del soldado caído en la Guerra de Malvinas, Elbio Aaujo, expresa un marco simbólico de interpretación de la muerte en la guerra de un grupo particular, y deviene para los familiares en un escenario de dramatización de la muerte que por la falta del cuerpo no pudo enfrentarse a través de sus formas habituales. Observaré al ritual desde el punto de vista de la performance, ya que nos permite ver de qué manera estamos refiriéndonos a experiencias vivenciadas en escenarios determinados, a través de los cuales es habitada la muerte de una persona, y significada de una manera particular. Así, veremos que a través del descubrimiento del busto, se sustituye la presencia del cuerpo ausente por otra materialidad y la puesta en escena actúa no sólo como un canal de comunicación a través del cual los deudos expresan al resto de la sociedad sus experiencias y los sentidos dados a la muerte en la guerra, sino que deviene también, para los familiares involucrados, en una práctica transformadora en cuanto a la reflexividad que propone sobre la condición social del muerto. Abstract In this paper we will show how the unveiling of the bust of Elbio Aaujo, a soldier fallen in the Malvinas War, expresses the symbolic framework for interpretation of death in battle of a particular group, at the same time becoming for his relatives the stage for dramatization of a death that could not be dealt with in the usual manner due to the lack of a body. We will deal with the ritual from the point of view of performance, since it allows us to see the ways experiences are lived in specific scenes, through which the death of a person is inhabited and signified in a particular way. Therefore, we will show that through the unveiling of the bust, the lack of the body is replaced by a different materiality and that the performance acts not only as a communication channel through which the bereaved

Ignatius of Loyola on medical education. Or: Should today's Jesuits continue to run health sciences schools?

Science.gov (United States)

Welie, Jos V M

2003-01-01

There are present 28 Jesuit colleges and universities in the United States, which together offer more than 50 health sciences degree programs. But as the Society's membership is shrinking and the financial risks involved in sponsoring health sciences education are rising, the question arises whether the Society should continue to sponsor health sciences degree programs. In fact, at least eight Jesuit health sciences schools have already closed their doors. This paper attempts to contribute to the resolution of this urgent question by reexamining Ignatius own views on health sciences education and, more specifically, his prohibition of the Society's sponsoring medical education. It concludes on the basis of an historical analysis of Ignatius' views that there is insufficient support for today's Jesuits to maintain their engagement in medical and health care education.

Managing boundaries between professional and lay nursing following the influenza pandemic, 1918-1919: insights for professional resilience today?

Wood, Pamela J

To examine lay-professional nursing boundaries, using challenges to the New Zealand nursing profession following the 1918-1919 influenza pandemic as the example. The influenza pandemic of 1918-1919 had an overwhelming international impact on communities and the nursing profession. After the pandemic, the expectation for communities to be able to nurse the sick reflects today's increasing reliance on families to care for people at home. It similarly raised questions about the profession's role and professional boundaries in relation to volunteer or lay nursing. In New Zealand, the postpandemic challenge to build community lay nursing capacity tested these boundaries. Historical research. Analysis of historical primary sources of official reports, newspaper accounts, articles in New Zealand's professional nursing journal Kai Tiaki and the memoir of Hester Maclean, the country's chief nurse. Interpretation of findings in relation to secondary sources examining similar historical tensions between professional and lay nursing, and to the more recent notion of professional resilience. Maclean guarded nursing's professional boundaries by maintaining considerable control over community instruction in nursing and by strenuously resisting the suggestion that this should be done in hospitals where professional nurses trained. This historical example shows how the nursing profession faced the perceived threat to its professional boundaries. It also shows how competing goals of building community lay nursing capacity and protecting professional boundaries can be effectively managed. In the context of a global nursing shortage, limited healthcare budgets and a consequently increasing reliance on households to provide care for family members, this historical research shows nurses today that similar issues have been faced and effectively managed in the past. © 2016 John Wiley & Sons Ltd.

To address the most dynamic and current issues concerning today's treatment options and promising research efforts regarding treatment for age-related macular degeneration. This review is aimed to serve as a practical reference for more in-depth reviews on the subject. An online review of the database PubMed and Ovid were performed, searching for the key words age-related macular degeneration, AMD, VEGF, treatment, PDT, steroids, bevacizumab, ranibizumab, VEGF-trap, radiation, combined therapy, as well as their compound phrases. The search was limited to articles published since 1985. All returned articles were carefully screened, and their references were manually reviewed for additional relevant data. The web page www.clinicaltrials.gov was also accessed in search of relevant research trials. A total of 363 articles were reviewed, including 64 additional articles extracted from the references. At the end, only 160 references were included in this review. Treatment for age-related macular degeneration is a very dynamic research field. While current treatments are mainly aimed at blocking vascular endothelial growth factor, future treatments seek to prevent vision loss because of scarring. Promising efforts have been made to address the dry form of the disease, which has lacked effective treatment.

Never before has the opportunity for terrestrial optical wireless communications links been so great. The high data rates attainable, up to OC-24, make it a very attractive and cost effective alternative to traditional fiber optic and microwave links. With today's demand for interactive multimedia-based applications, such as video conferencing and telemedicine, optical wireless products are the only ones that can provide the needed bandwidth in situations when it is too costly or impossible to install fiber optic cable. Recent developments in laser and optics technologies, in addition to auto beam tracking, permit transmission units to achieve excellent performance rates in all weather conditions.

DEVELOPMENT OF MIGRATION POTENTIAL IN HUNGARY FROM 2000 UNTIL TODAY

Directory of Open Access Journals (Sweden)

Margit Csipkés

2018-03-01

Full Text Available Hearing the words “international migration”, two things might come to our mind. One of them is the emigration process and the other is the wave of refugees. In our study, we examined the changes of the number of employees emigrating from Hungary from 2000 until today. Nowadays, the examination of the migration potential is an important topic in Hungary, since the rate of Hungarian emigrants started to grow after 2006 and the rate of growth became even faster after 2010. The reason of the acceleration was the opening of the Austrian and German labour market. The actuality of the topic is based on the fact that international emigration merges the labour market’s processes, influences the given country’s employment level, moreover it has an influencing role on the rate of wages. Emigration from a given state has several reasons: natural disasters, war, marginalization, economic reasons, etc. In our study, we examine emigration caused by economic reasons. We have to take into consideration that measuring emigration processes is a difficult task, due to the lack of data. The reason of the deficiency is that those who leave the country, often forget to report their leaving. From 1 March 2013, only the permanent foreign settlement should be reported towards the administration (District Office, Consulate. Earlier, temporary (more than 3 months settlement was also obligatory to be reported. Many of the leaving Hungarians do not report their leaving, however working abroad for more than 3 months should be reported towards social insurance organizations and tax authorities. I would like to emphasise that my migration potential presentation does not show a direct correlation with the actual migration. However, this study might show the expected movement rates and the composition of emigrants.

Full Text Available Inspired by her student’s overwhelmingly positive interpretation of Judith as a model for women’s liberation in diverse African contexts – despite the debate around the feminist value of Judith-Judith – the author deals with what could possibly allow men and women, particularly the latter, to interpret Judith positively today. Given her interest in Jungian individuation theory and Ancient Near Eastern (ANE mythology, the author investigates the subject matter by exploring Judith’s relation to male and female individuation patterns, the myths of the hero’s quest and Demeter-Kore, and ANE warrior-goddess myths.
