General aviation activity and avionics survey. Annual summary report, CY 1985  

SciTech Connect

This report presents the results and a description of the 1985 General Aviation Activity and Avionics Survey. The survey was conducted during 1986 by the FAA to obtain information on the activity and avionics of the United States registered general aviation aircraft fleet, the dominant component of civil aviation in the U.S. The survey was based on a statistically selected sample of about 10.3 percent of the general aviation fleet. A responses rate of 63.7 percent was obtained. Survey results based upon response but are expanded upward to represent the total population. Survey results revealed that during 1985 an estimated 34.1 million hours of flying time were logged and 88.7 million operations were performed by the 210,654 active general aviation aircraft in the U.S. fleet. The mean annual flight time per aircraft was 158.2 hours. The active aircraft represented about 77.9 percent of the registered general aviation fleet. The report contains breakdowns of these and other statistics by manufacturer/model group, aircraft, state and region of based aircraft, and primary use. Also included are fuel consumption, lifetime airframe hours, avionics, engine hours, and miles flown estimates, as well as tables for detailed analysis of the avionics capabilities of the general aviation fleet. New to the report this year are estimates of the number of landings, IFR hours flown, and the cost and grade of fuel consumed by the GA fleet.

Error, stress, and teamwork in medicine and aviation: cross sectional surveys  

PubMed Central

Objectives: To survey operating theatre and intensive care unit staff about attitudes concerning error, stress, and teamwork and to compare these attitudes with those of airline cockpit crew. Design: Cross sectional surveys. Setting: Urban teaching and non-teaching hospitals in the United States, Israel, Germany, Switzerland, and Italy. Major airlines around the world. Participants: 1033 doctors, nurses, fellows, and residents working in operating theatres and intensive care units and over 30?000 cockpit crew members (captains, first officers, and second officers). Main outcome measures: Perceptions of error, stress, and teamwork. Results: Pilots were least likely to deny the effects of fatigue on performance (26% v 70% of consultant surgeons and 47% of consultant anaesthetists). Most pilots (97%) and intensive care staff (94%) rejected steep hierarchies (in which senior team members are not open to input from junior members), but only 55% of consultant surgeons rejected such hierarchies. High levels of teamwork with consultant surgeons were reported by 73% of surgical residents, 64% of consultant surgeons, 39% of anaesthesia consultants, 28% of surgical nurses, 25% of anaesthetic nurses, and 10% of anaesthetic residents. Only a third of staff reported that errors are handled appropriately at their hospital. A third of intensive care staff did not acknowledge that they make errors. Over half of intensive care staff reported that they find it difficult to discuss mistakes. Conclusions: Medical staff reported that error is important but difficult to discuss and not handled well in their hospital. Barriers to discussing error are more important since medical staff seem to deny the effect of stress and fatigue on performance. Further problems include differing perceptions of teamwork among team members and reluctance of senior theatre staff to accept input from junior members.

[Aviation physiology].  

PubMed

Aviation physiology should be known at least in parts by the physicians advising air travellers. Due to reducing atmospheric pressure at altitude gas volume in body cavities expands (Boyle's law). This might not be a problem during ascend since air can disappear easily through natural ways. However, air must return to body cavities during descend and a person with a cold may suffer from painful barotitis. Hypoxia is mostly due to a reduced pO2 in high altitude (Daltons's Law). This may be prevented by an aircraft cabin or supplemented oxygen. Decompression sickness is very rare in aviation but divers should comply to a dive free interval before flying. PMID:10568247

The relationship between aviation activities and ultrafine particulate matter concentrations near a mid-sized airport  

NASA Astrophysics Data System (ADS)

Aircraft contribute to emissions of ultrafine particulate matter (UFP) and other air pollutants, with corresponding impacts on community-level exposures near active airports. However, it is challenging to isolate the contribution of aircraft from local road traffic and other nearby combustion sources. In this study, we used high-resolution monitoring and flight activity data to quantify contributions from landing and take-off operations (LTO) to UFP concentrations. UFP concentrations were monitored with 1-min resolution at four monitoring sites surrounding T.F. Green Airport in Warwick, RI, in three one-week campaigns across different seasons in 2007 and 2008. Along with pollutant monitoring, wind data were collected and runway-specific LTO data were obtained from airport officials. We developed regression models in which wind speed and direction were included as a nonparametric smooth spatial term using thin-plate splines applied to wind velocity vectors and fitted using linear mixed models. To better pinpoint the timing in the LTO cycle most contributing to elevated concentrations, we used regression models with lag terms for flight activity (ranging from 5 min before to 5 min after the departure or arrival). Results suggest positive associations between UFP concentrations and LTO activities, especially for departures when an aircraft moves near or passes a monitoring site. Departures of jet engine aircrafts on a runway proximate to one of the monitors have a maximal impact 1 min prior to take-off, with median absolute contributions during those minutes of 7400 particles cm-3 (range: 1100-70,000 particles cm-3). Across all observations, our models indicate median (95th, 99th percentile) percent contribution for all LTO activities of 9.8% (54%, 72%) and 6.6% (39%, 55%) for the two sites proximate to the airport's principal runway, and 4.7% (24%, 36%) and 1.8% (22%, 31%) for the remaining two sites. Our analysis illustrates the complexity of aviation impacts on local air quality and allows for quantification of the marginal contribution of LTO activity relative to other nearby sources.

Aviation Lubricants  

NASA Astrophysics Data System (ADS)

Aviation lubricants must be extremely reliable, withstand high specific loadings and extreme environmental conditions within short times. Requirements are critical. Piston engines increasingly use multi-grade oils, single grades are still used extensively, with anti-wear and anti-corrosion additives for some classes of engines. The main gas turbine lubricant problem is transient heat exposure, the main base oils used are synthetic polyol esters which minimise thermal degradation. Aminic anti-oxidants are used together with anti-wear/load-carrying, corrosion inhibitor and anti-foam additives. The majority of formulation viscosities are 5 cSt at 100°C. Other considerations are seal compatibility and coking tendency.

Aviation graduates' competencies, 2000--2007: Perceptions of aviation educators and industry representatives in the United States  

NASA Astrophysics Data System (ADS)

This study surveyed the perceptions of collegiate aviation educators, collegiate aviation institution representatives, and aviation industry stakeholders who were members of the University Aviation Association as of February 5, 2007. Survey forms were sent to 353 prospective participants and there was an overall response rate of 47.6%. The survey consisted of a list of 16 knowledge and skill competencies with Likert-type responses for each participant to indicate the level of importance each placed upon those competencies for collegiate aviation graduates and of the level of satisfaction each had that collegiate aviation graduates actually possessed those competencies upon graduation. Two open-ended questions pertained to the strengths and weaknesses of collegiate aviation programs or their graduates. Another allowed for general comments. The statistical analyses indicated that all three groups were most satisfied with graduates' technical skills and least satisfied with communications skills. Analyses indicated that a balance of technical skills and a liberal education was essential for program success. All knowledge and skill competencies were shown to have high to very high importance levels, but only medium to high satisfaction levels. Results indicated that graduates were perceived to possess all stated competencies, but to a lesser degree than desired. Successful collegiate aviation programs existed, but there was room for improvement. Success was program or graduate speck, with no ubiquitous definition of what constituted a successful collegiate aviation program. Aviation industry needs must be addressed by academia for any collegiate aviation program to be successful, but results indicated that the aviation industry needs to take a larger role in the development and refinement of collegiate aviation programs. Finances for institutions, programs, and students were a major concern for the foreseeable future. Administrators should consider how their actions affect the overall success of their programs.

Problem Solving through Aviation  

NSDL National Science Digital Library

A unit that focuses on problem solving through real life situations that involveaviation. In spite of a variety of shapes and sizes all airplanes fly in the same way, and the problems of the aviation industry are basically the same. Some of the problems in this unit deal with the tests that have already been in the United States by the National Aeronautics and Space Administration, the Federal Aviation Agency, and the Department of Defense in order to ensure safety, convenience, and efficiency in aviation.

Initial Cognitive Performance Predicts Longitudinal Aviator Performance  

PubMed Central

Objectives. The goal of the study was to improve prediction of longitudinal flight simulator performance by studying cognitive factors that may moderate the influence of chronological age. Method. We examined age-related change in aviation performance in aircraft pilots in relation to baseline cognitive ability measures and aviation expertise. Participants were aircraft pilots (N = 276) aged 40–77.9. Flight simulator performance and cognition were tested yearly; there were an average of 4.3 (± 2.7; range 1–13) data points per participant. Each participant was classified into one of the three levels of aviation expertise based on Federal Aviation Administration pilot proficiency ratings: least, moderate, or high expertise. Results. Addition of measures of cognitive processing speed and executive function to a model of age-related change in aviation performance significantly improved the model. Processing speed and executive function performance interacted such that the slowest rate of decline in flight simulator performance was found in aviators with the highest scores on tests of these abilities. Expertise was beneficial to pilots across the age range studied; however, expertise did not show evidence of reducing the effect of age. Discussion. These data suggest that longitudinal performance on an important real-world activity can be predicted by initial assessment of relevant cognitive abilities.

The actual development of European aviation safety requirements in aviation medicine: prospects of future EASA requirements.  

PubMed

Common Rules for Aviation Safety had been developed under the aegis of the Joint Aviation Authorities in the 1990s. In 2002 the Basic Regulation 1592/2002 was the founding document of a new entity, the European Aviation Safety Agency. Areas of activity were Certification and Maintenance of aircraft. On 18 March the new Basic Regulation 216/2008, repealing the original Basic Regulation was published and applicable from 08 April on. The included Essential Requirements extended the competencies of EASA inter alia to Pilot Licensing and Flight Operations. The future aeromedical requirements will be included as Annex II in another Implementing Regulation on Personnel Licensing. The detailed provisions will be published as guidance material. The proposals for these provisions have been published on 05 June 2008 as NPA 2008- 17c. After public consultation, processing of comments and final adoption the new proposals may be applicable form the second half of 2009 on. A transition period of four year will apply. Whereas the provisions are based on Joint Aviation Requirement-Flight Crew Licensing (JAR-FCL) 3, a new Light Aircraft Pilot Licence (LAPL) project and the details of the associated medical certification regarding general practitioners will be something new in aviation medicine. This paper consists of 6 sections. The introduction outlines the idea of international aviation safety. The second section describes the development of the Joint Aviation Authorities (JAA), the first step to common rules for aviation safety in Europe. The third section encompasses a major change as next step: the foundation of the European Aviation Safety Agency (EASA) and the development of its rules. In the following section provides an outline of the new medical requirements. Section five emphasizes the new concept of a Leisure Pilot Licence. The last section gives an outlook on ongoing rulemaking activities and the opportunities of the public to participate in them. PMID:19561781

A survey of orphan enzyme activities  

PubMed Central

Background Using computational database searches, we have demonstrated previously that no gene sequences could be found for at least 36% of enzyme activities that have been assigned an Enzyme Commission number. Here we present a follow-up literature-based survey involving a statistically significant sample of such "orphan" activities. The survey was intended to determine whether sequences for these enzyme activities are truly unknown, or whether these sequences are absent from the public sequence databases but can be found in the literature. Results We demonstrate that for ~80% of sampled orphans, the absence of sequence data is bona fide. Our analyses further substantiate the notion that many of these enzyme activities play biologically important roles. Conclusion This survey points toward significant scientific cost of having such a large fraction of characterized enzyme activities disconnected from sequence data. It also suggests that a larger effort, beginning with a comprehensive survey of all putative orphan activities, would resolve nearly 300 artifactual orphans and reconnect a wealth of enzyme research with modern genomics. For these reasons, we propose that a systematic effort to identify the cognate genes of orphan enzymes be undertaken.

Alcohol fuels for aviation  

SciTech Connect

The ten-fold increase in aviation fuel prices in eight years has caused a reassessment of alcohol fuels. In a recent test, methanol fuel-flow rate was high at takeoff, and levelled off at 10,000 feet, but above 18,000 fell 30% below avgas use. Because methanol sells thirty cents below avgas per gallon it is already an attractive fuel for piston-engine aircraft. But as 95% of aviation fuel is burned as kerosene in turbines a test program has been set up to look at the performance of small shaft turbine engines with various combinations of alcohols and water, and of straight methanol, and to look at major thrust engine at optimum fuel as well. These tests should determine the overall alcohol potentials for aviation. The tests will also tell if the breakthrough will be modest or major.

Fatigue countermeasures in aviation.  

PubMed

Pilot fatigue is a significant problem in modern aviation operations, largely because of the unpredictable work hours, long duty periods, circadian disruptions, and insufficient sleep that are commonplace in both civilian and military flight operations. The full impact of fatigue is often underappreciated, but many of its deleterious effects have long been known. Compared to people who are well-rested, people who are sleep deprived think and move more slowly, make more mistakes, and have memory difficulties. These negative effects may and do lead to aviation errors and accidents. In the 1930s, flight time limitations, suggested layover durations, and aircrew sleep recommendations were developed in an attempt to mitigate aircrew fatigue. Unfortunately, there have been few changes to aircrew scheduling provisions and flight time limitations since the time they were first introduced, despite evidence that updates are needed. Although the scientific understanding of fatigue, sleep, shift work, and circadian physiology has advanced significantly over the past several decades, current regulations and industry practices have in large part failed to adequately incorporate the new knowledge. Thus, the problem of pilot fatigue has steadily increased along with fatigue-related concerns over air safety. Accident statistics, reports from pilots themselves, and operational flight studies all show that fatigue is a growing concern within aviation operations. This position paper reviews the relevant scientific literature, summarizes applicable U.S. civilian and military flight regulations, evaluates various in-flight and pre-/postflight fatigue countermeasures, and describes emerging technologies for detecting and countering fatigue. Following the discussion of each major issue, position statements address ways to deal with fatigue in specific contexts with the goal of using current scientific knowledge to update policy and provide tools and techniques for improving air safety.

Scope and method of study. The purpose of this study was to examine the academic advisement satisfaction of 510, Oklahoma aviation students at four southwestern state universities. Students were given the opportunity to complete a survey during class meetings or during aviation student orientation, spring 2002. The Statistical Package for the Social Sciences (S.P.S.S.) software program was utilized to determine the mean, median, mode, and range of data. Data is also presented in frequencies, percentages and Chi square statistical test analysis to illustrate rank order of academic advisement satisfaction between the four participating aviation undergraduate programs. Findings and conclusions. Of the 510 aviation students surveyed, 268 or 52.5% completed and returned surveys. Demographics indicated that aviation students at Programs A, C & D were predominately advised by aviation faculty, and at Program B by an advisor in an advisement center. The majority were seniors, under the age of 25, evenly split between in-state and out-of-state student residency, enrolled full-time, possessed an average GPA of 3.2, were first-generation aviation majors, and were male. Based on Chi square analysis the rank order of academic advisement satisfaction between the four aviation programs was: Program B - 99.9%, Program D - 92.0%, Program C - 87.9% and Program A - 83.9%. Rank order for academic advisement satisfaction concerning aviation career advisement was: Program B - 76.0%, Program D - 66.9%, Program A - 54.6%, and Program C - 49.3%. Rank order for academic advisement satisfaction concerning aviation student personal confidence in advisors was: Program B - 99.4%, Program D - 95.6%, Program A - 85.4%, and Program C - 84.5%. Written open responses relating to academic advisement developed into three categories of academic, personal and career, and were recorded for 194, or 72.3% of the 268 students completing the survey instrument.

The price and availability of fuel continues to be a major barrier to the free expansion of general aviation. Although this increase in fuel prices had a more severe impact on airlines, it has also slowed the demand for general aviation aircraft. With the sales of general aviation aircraft in a depressed state, the development of alternative fuels such as liquid methane, ethanol, methanol, and automobile gasoline can help spur the industry back to health. Recent flight tests of these alternative fuels are examined.

Active optics in Large Synoptic Survey Telescope  

NASA Astrophysics Data System (ADS)

The Large Synoptic Survey Telescope (LSST) has a 3.5º field of view and F/1.2 focus that makes the performance quite sensitive to the perturbations of misalignments and mirror surface deformations. In order to maintain the image quality, LSST has an active optics system (AOS) to measure and correct those perturbations in a closed loop. The perturbed wavefront errors are measured by the wavefront sensors (WFS) located at the four corners of the focal plane. The perturbations are solved by the non-linear least square algorithm by minimizing the rms variation of the measured and baseline designed wavefront errors. Then the correction is realized by applying the inverse of the perturbations to the optical system. In this paper, we will describe the correction processing in the LSST AOS. We also will discuss the application of the algorithm, the properties of the sensitivity matrix and the stabilities of the correction. A simulation model, using ZEMAX as a ray tracing engine and MATLAB as an analysis platform, is set up to simulate the testing and correction loop of the LSST AOS. Several simulation examples and results are presented.

Ash cloud aviation advisories  

SciTech Connect

During the recent (12--22 June 1991) Mount Pinatubo volcano eruptions, the US Air Force Global Weather Central (AFGWC) requested assistance of the US Department of Energy`s Atmospheric Release Advisory Capability (ARAC) in creating volcanic ash cloud aviation advisories for the region of the Philippine Islands. Through application of its three-dimensional material transport and diffusion models using AFGWC meteorological analysis and forecast wind fields ARAC developed extensive analysis and 12-hourly forecast ash cloud position advisories extending to 48 hours for a period of five days. The advisories consisted of ``relative`` ash cloud concentrations in ten layers (surface-5,000 feet, 5,000--10,000 feet and every 10,000 feet to 90,000 feet). The ash was represented as a log-normal size distribution of 10--200 {mu}m diameter solid particles. Size-dependent ``ashfall`` was simulated over time as the eruption clouds dispersed. Except for an internal experimental attempt to model one of the Mount Redoubt, Alaska, eruptions (12/89), ARAC had no prior experience in modeling volcanic eruption ash hazards. For the cataclysmic eruption of 15--16 June, the complex three-dimensional atmospheric structure of the region produced dramatically divergent ash cloud patterns. The large eruptions (> 7--10 km) produced ash plume clouds with strong westward transport over the South China Sea, Southeast Asia, India and beyond. The low-level eruptions (< 7 km) and quasi-steady-state venting produced a plume which generally dispersed to the north and east throughout the support period. Modeling the sequence of eruptions presented a unique challenge. Although the initial approach proved viable, further refinement is necessary and possible. A distinct need exists to quantify eruptions consistently such that ``relative`` ash concentrations relate to specific aviation hazard categories.

Health survey reliability in an active duty population.  

PubMed

We examined the reliability of data collected from the Health Enrollment Assessment Review (HEAR) survey, a self-report instrument administered by the Department of Defense styled after the Behavioral Risk Factor Surveillance System (BRFSS). Survey responses from a convenience sample of active duty service members who completed a HEAR survey on two occasions were examined. We measured test-retest reliability by comparing individuals' responses to several of the survey items and compared HEAR reliability patterns with the reliability patterns of similar studies conducted with the BRFSS. The majority of estimates reflected fair to excellent reliability. We found substantial agreement between the results of this investigation and similar BRFSS studies. Our findings support the reliability of responses from the HEAR survey for active duty military members. Our results were generally consistent with those of other studies despite differences in survey administration, respondent characteristics, and privacy guarantees. PMID:11469037

Two independently conducted surveys on sustainability - one into the 'views and values' of NHS 'leaders', and the other questioning the public about the importance of the 'green agenda' in the NHS, and their opinions on how the service might most effectively reduce its carbon footprint, form the basis of Sustainability in the NHS: Health Check 2012, a new NHS Sustainable Development Unit (NHS SDU) publication. As HEJ editor Jonathan Baillie reports, the new document also presents updated data on the 'size' of the carbon footprint of the NHS in England, showing that, although good work by a number of Trusts in the past two years has seen healthcare-generated carbon emissions start to 'level off', the biggest contributors have been the current health service spending review, and the increased national availability of renewable energy.

Aviation Medicine: global historical perspectives and the development of Aviation Medicine alongside the growth of Singapore's aviation landscape.  

PubMed

Aviation Medicine traces its roots to high altitude physiology more than 400 years ago. Since then, great strides have been made in this medical specialty, initially catalysed by the need to reduce pilot medical attrition during the World Wars, and more recently, fuelled by the explosive growth in globalised commercial air travel. This paper traces the historical milestones in Aviation Medicine, and maps its development in Singapore since the 1960s. Advancements in military aviation platforms and technology as well as the establishment of Singapore as an international aviation hub have propelled Aviation Medicine in Singapore to the forefront of many domains. These span Aviation Physiology training, selection medical standards, performance maximisation, as well as crew and passenger protection against communicable diseases arising from air travel. The year 2011 marks the centennial milestone of the first manned flight in Singapore, paving the way for further growth of Aviation Medicine as a mature specialty in Singapore. PMID:21633764

Aviation combustion toxicology: an overview.  

PubMed

Aviation combustion toxicology is a subspecialty of the field of aerospace toxicology, which is composed of aerospace and toxicology. The term aerospace, that is, the environment extending above and beyond the surface of the Earth, is also used to represent the combined fields of aeronautics and astronautics. Aviation is another term interchangeably used with aerospace and aeronautics and is explained as the science and art of operating powered aircraft. Toxicology deals with the adverse effects of substances on living organisms. Although toxicology borrows knowledge from biology, chemistry, immunology, pathology, physiology, and public health, the most closely related field to toxicology is pharmacology. Economic toxicology, environmental toxicology, and forensic toxicology, including combustion toxicology, are the three main branches of toxicology. In this overview, a literature search for the period of 1960-2007 was performed and information related to aviation combustion toxicology collected. The overview included introduction; combustion, fire, and smoke; smoke gas toxicity; aircraft material testing; fire gases and their interactive effects; result interpretation; carboxyhemoglobin and blood cyanide ion levels; pyrolytic products of aircraft engine oils, fluids, and lubricants; and references. This review is anticipated to be an informative resource for aviation combustion toxicology and fire-related casualties. PMID:20109297

A total of 654 centers from 48 countries were contacted for the 2010 survey. In all, 634 centers reported a total of 33?362 hematopoietic SCT (HSCT) with 30?012 patients receiving their first transplant (12?276 allogeneic (41%) and 17?736 autologous (59%)). Main indications were leukemias: 9355 (31%; 93% allogeneic), lymphoid neoplasias specifically Non Hodgkin's lymphoma, Hodgkin's lymphoma and plasma cell disorders: 17?362 (58%; 12% allogeneic), solid tumors: 1585 (5%; 6% allogeneic) and non-malignant disorders: 1609 (6%; 88% allogeneic). There were more unrelated donors than HLA-identical sibling donors (53% versus 41%); the proportion of peripheral blood as stem cell source was 99% for autologous and 71% for allogeneic HSCT. Cord blood was primarily used in allogeneic transplants (6% of total) with three autologous cord blood HSCT being reported. The number of transplants has increased by 19% since 2005 (allogeneic 37% and autologous 9%) and continued to increase by about 1100 HSCT per year since 2000. Patterns of increase were distinct and different. The data show the development of transplantation in Europe since 1990, with the number of patients receiving a HSCT increasing from 4200 to over 30?000 annually. The most impressive trend seen is the steady increase of unrelated donor transplantation, in parallel to the availability of unrelated donors through donor registries. PMID:22543746

Aviation security: A system's perspective  

SciTech Connect

For many years the aviation industry and airports operated with security methods and equipment common to most other large industrial complexes. At that time, the security systems primarily provided asset and property protection. However, soon after the first aircraft hijacking the focus of security shifted to emphasize the security requirements necessary for protecting the traveling public and the one feature of the aviation industry that makes it unique---the airplane. The airplane and its operation offered attractive opportunities for the homesick refugee, the mentally unstable person and the terrorist wanting to make a political statement. The airport and its aircraft were the prime targets requiring enhanced security against this escalated threat. In response, the FAA, airport operators and air carriers began to develop plans for increasing security and assigning responsibilities for implementation.

Taxation of United States general aviation  

NASA Astrophysics Data System (ADS)

General aviation in the United States has been an important part of the economy and American life. General aviation is defined as all flying excluding military and scheduled airline operations, and is utilized in many areas of our society. The majority of aircraft operations and airports in the United States are categorized as general aviation, and general aviation contributes more than one percent to the United States gross domestic product each year. Despite the many benefits of general aviation, the lead emissions from aviation gasoline consumption are of great concern. General aviation emits over half the lead emissions in the United States or over 630 tons in 2005. The other significant negative externality attributed to general aviation usage is aircraft accidents. General aviation accidents have caused over 8000 fatalities over the period 1994-2006. A recent Federal Aviation Administration proposed increase in the aviation gasoline tax from 19.4 to 70.1 cents per gallon has renewed interest in better understanding the implications of such a tax increase as well as the possible optimal rate of taxation. Few studies have examined aviation fuel elasticities and all have failed to study general aviation fuel elasticities. Chapter one fills that gap and examines the elasticity of aviation gasoline consumption in United States general aviation. Utilizing aggregate time series and dynamic panel data, the price and income elasticities of demand are estimated. The price elasticity of demand for aviation gasoline is estimated to range from -0.093 to -0.185 in the short-run and from -0.132 to -0.303 in the long-run. These results prove to be similar in magnitude to automobile gasoline elasticities and therefore tax policies could more closely mirror those of automobile tax policies. The second chapter examines the costs associated with general aviation accidents. Given the large number of general aviation operations as well as the large number of fatalities and injuries attributed to general aviation accidents in the United States, understanding the costs to society is of great importance. This chapter estimates the direct and indirect costs associated with general aviation accidents in the United States. The indirect costs are estimated via the human capital approach in addition to the willingness-to-pay approach. The average annual accident costs attributed to general aviation are found to be 2.32 billion and 3.81 billion (2006 US) utilizing the human capital approach and willingness-to-pay approach, respectively. These values appear to be fairly robust when subjected to a sensitivity analysis. These costs highlight the large societal benefits from accident and fatality reduction. The final chapter derives a second-best optimal aviation gasoline tax developed from previous general equilibrium frameworks. This optimal tax reflects both the lead pollution and accident externalities, as well as the balance between excise taxes and labor taxes to finance government spending. The calculated optimal tax rate is 4.07 per gallon, which is over 20 times greater than the current tax rate and 5 times greater than the Federal Aviation Administration proposed tax rate. The calculated optimal tax rate is also over 3 times greater than automobile gasoline optimal tax rates calculated by previous studies. The Pigovian component is 1.36, and we observe that the accident externality is taxed more severely than the pollution externality. The largest component of the optimal tax rate is the Ramsey component. At 2.70, the Ramsey component reflects the ability of the government to raise revenue aviation gasoline which is price inelastic. The calculated optimal tax is estimated to reduce lead emissions by over 10 percent and reduce accidents by 20 percent. Although unlikely to be adopted by policy makers, the optimal tax benefits are apparent and it sheds light on the need to reduce these negative externalities via policy changes.

U. S. Energy: aviation perspective  

SciTech Connect

This report is a sequel/update of The Impact of Petroleum, Synthetic and Cryogenic Fuels on Civil Aviation, DOT/FAA/EM-82/29, June, 1982. Where the earlier report is more concerned with energy resources and availability, this report is more concerned with energy supply/demand balance and with prices. The report reviews world and U.S. energy, U.S. transportation energy, aviation fuel, natural gas, alternative fuels and energy sources, synthetic fuels, aviation fuel conservation, and petroleum price vulnerability. It draws heavily on The National Energy Policy Plan of 1983 and its supporting documents. World oil production and prices should remain generally steady for thirty to fifty years, growing slightly faster than the world economy. Near-term prices should be softer. OPEC can raise prices whenever demand for its production exceeds 80% of OPEC production capacity. The U.S. could delay or reverse future price rises by encouraging, or at least reducing restrictions against, domestic production. All future energy forecasts are risky. A disruption in crude production at any time until at least year 2000, can easily increase fuel prices by 100%.

National Human Activity Pattern Survey (NHAPS): Use of nationwide activity data for human exposure assessment  

SciTech Connect

The National Human Activity Pattern Survey (NHAPS) was initiated to fill a need for updated activity information on a nationwide scale. The NHAPS, which begain in September, 1992, is a two-year probability-based national telephone interview survey of approximately 10,000 persons that is being conducted by the University of Maryland Survey Research Center assisted by the USEPA to ascertain the time, location, and other characteristics of those activities which are most relevant to estimating pollutant exposure. The survey design, location and activity codes, data examples, and appropriate analyses are described for the NHAPS data base. Time-diary data from this survey will provide standardized activity reports which, when available in early 1995, will be used to refine current human exposure models. Activity diary data have been effectively used in the following types of analyses: descriptive, relational, temporal, and exposure modeling. Examples of these analyses will be discussed and illustrated with data from previous activity surveys, including the recently available California survey. The applicability of these previous analyses to the new NHAPS data will be emphasized.

Characteristics of successful aviation leaders of Oklahoma  

NASA Astrophysics Data System (ADS)

Scope and method of study. The purpose of the study was to examine the personal traits, skills, practices, behaviors, background, academic, and career success patterns of selected aviation leaders in Oklahoma. A purposive sample of 18 leaders who had achieved a top-ranked position of aviation leadership in an organization or a position of influence in the community was selected for interview. The leaders chosen for interview came from a variety of aviation organizations including government, academia, military, corporate aviation, and air carrier leadership as well as community leadership (specifically those aviation personnel who were engaged in a political or civic leadership role). Findings and conclusions. This study identified no common career choices, educational, family, or other background factors exclusively responsible for leadership success of all of the participants. Some of the more significant findings were that a high percentage of the leaders held undergraduate and advanced degrees; however, success had been achieved by some who had little or no college education. Aviation technical experience was not a prerequisite for aviation leadership success in that a significant number of the participants held no airman rating and some had entered positions of aviation leadership from non-aviation related careers. All had received some positive learning experience from their family background even those backgrounds which were less than desirable. All of the participants had been involved in volunteer civic or humanitarian leadership roles, and all had received numerous honors. The most frequently identified value expressed by the leaders was honesty; the predominant management style was participative with a strong backup style for directing, the most important skills were communication and listening skills, and the most frequently mentioned characteristics of success were honesty, credibility, vision, high standards, love for aviation and fiscal responsibility. The most frequently identified curriculum need across all aviation disciplines was that of communication skills.

Status report on the survey and alignment activities at Fermilab  

SciTech Connect

The surveying and alignment activities at Fermilab are the responsibility of the Alignment and Metrology Group. The Group supports and interacts with physicists and engineers working on any particular project, from the facility construction phase to the installation and final alignment of components in the beam line. One of the goals of the Alignment and Metrology Group is to upgrade the old survey networks in the tunnel using modern surveying technology, such as the Laser Tracker for tunnel networks and GPS for the surface networks. According to the job needs, all surveys are done with Laser Trackers and/or Videogrammetry (V-STARS) systems for spatial coordinates; optical and electronic levels are used for elevations, Gyro-Theodolite for azimuths, Mekometer for distances and GPS for baseline vectors. The group has recently purchased two new API Laser Trackers, one INCA3 camera for the V-Stars, and one DNA03 digital level. This report presents the projects and major activities of the Alignment and Metrology Group at Fermilab during the period of 2000 to 2004. It focuses on the most important current projects, especially those that have to be completed during the currently scheduled three-month shutdown period. Future projects, in addition to the status of the current projects, are also presented.

Cardiac pacing and aviation.  

PubMed

Certain applicants with stable disturbances of rhythm or conduction requiring cardiac pacing, in whom no other disqualifying condition is present, may be considered fit for medical certification restricted to multi-crew operations. The reliability of modern pacing systems appears adequate to permit restricted certification even in pacemaker dependent subjects except for certain models of pacemakers and leads known to be at increased risk of failure. These are to be avoided. There is little evidence to suggest that newer devices are any more reliable than their predecessors. Single and dual chamber systems appear to have similar reliability up to 4 years, after which time significant attrition of dual chamber devices occurs, principally due to battery depletion. All devices require increased scrutiny as they approach their end of life as predicted from longevity data and pacing characteristics. Unipolar and bipolar leads are of similar reliability, apart from a number of specific bipolar polyurethane leads which have been identified. Atrial leads, particularly those without active fixation, are less secure than ventricular leads and applicants who are dependent on atrial sensing or pacing should be denied certification. Bipolar leads are to be preferred due to the lower risk of myopotential and exogenous EMI. Sensor-driven adaptive-rate pacing systems using active sensors may have reduced longevity and require close scrutiny. Activity-sensing devices using piezoelectric crystal sensors may be subject to significant rate rises in rotary wing aircraft. The impracticality of restricted certification in helicopters will, in any event, preclude certification. Such devices would best be avoided in hovercraft (air cushioned vehicle) pilots. Only minor rate rises are likely in fixed-wing aircraft which are unlikely to be of significance. Anti-tachycardia devices and implanted defibrillators are inconsistent with any form of certification to fly. PMID:1493823

National Survey of Children's Hospitals on Legacy-Making Activities  

PubMed Central

Abstract Objective Many hospitals offer legacy-building activities for children with serious illnesses or their family members, yet legacy-making has received little empirical attention. This descriptive cross-sectional study examined healthcare provider perceptions of legacy-making activities (e.g., memory books) currently offered by hospitals to pediatric patients and their families. Methods Healthcare providers in seventy-seven (100%) teaching children's hospitals across the United States completed an electronic survey. Results Nearly all providers surveyed reported offering legacy-making activities to ill children and their families, with patients and families usually completing the activity together. Most activities were offered before a patient died and when cure is no longer being sought. Perceived outcomes included benefit to bereaved families and a tangible memento of their deceased child. Conclusion Legacy-making may enhance life and decrease suffering for dying children and their families. Healthcare professionals can facilitate opportunities for children and their families to build legacies. Additional research is needed to examine activities across different age groups and conditions, the best time to offer such activities, and associations with positive and negative outcomes for ill children, their family members, and the bereaved.

Scientists Outline Volcanic Ash Risks to Aviation  

NASA Astrophysics Data System (ADS)

The ash clouds that belched out of Iceland's Eyjafjallajökull volcano last spring and dispersed over much of Europe, temporarily paralyzing aviation, were vast smoke signal warnings about the hazard that volcanic ash poses for air traffic around the world. At a 15 December news briefing at the AGU Fall Meeting in San Francisco, two experts with the U.S. Geological Survey (USGS) presented an overview of the damage airplanes can sustain from rock fragment- and mineral fragment-laden ash, an update on efforts to mitigate the hazard of ash, and an outline of further measures that are needed to address the problem. Between 1953 and 2009, there were 129 reported encounters of aircraft with volcanic ash clouds, according to a newly released USGS document cited at the briefing. The report, “Encounters of aircraft with volcanic ash clouds: A compilation of known incidents, 1953-2009,” by Marianne Guffanti, Thomas Casadevall, and Karin Budding, indicates that 26 encounters involved significant damage to the airplanes; nine of those incidents resulted in engine shutdown during flight. The report, which does not focus on the effects on airplanes of cumulative exposure to dilute ash and does not include data since 2009, indicates that “ash clouds continue to pose substantial risks to safe and efficient air travel globally.”

Shock waves in aviation security and safety  

NASA Astrophysics Data System (ADS)

Accident investigations such as of Pan Am 103 and TWA 800 reveal the key role of shock-wave propagation in destroying the aircraft when an on-board explosion occurs. This paper surveys shock wave propagation inside an aircraft fuselage, caused either by a terrorist device or by accident, and provides some new experimental results. While aircraft-hardening research has been under way for more than a decade, no such experiments to date have used the crucial tool of high-speed optical imaging to visualize shock motion. Here, Penn State's Full-Scale Schlieren flow visualization facility yields the first shock-motion images in aviation security scenarios: 1) Explosions beneath full-size aircraft seats occupied by mannequins, 2) Explosions inside partially-filled luggage containers, and 3) Luggage-container explosions resulting in hull-holing. Both single-frame images and drum-camera movies are obtained. The implications of these results are discussed, though the overall topic must still be considered in its infancy.

[Brief history of the otolaryngology department in the Air-Force Institute of aviation medicine].  

PubMed

Air Force Institute of Aviation Medicine with Clinics, celebrating its 67th anniversary, continues the traditions of research institute of Aeromedical Studies Centre, established in 1928. In 1936 it was renamed in to Leibnitz Institute of Medical Studies. The activity of aeromedical service was interrupted by the outbreak of World War II and continued in the Laboratory of Aviation Physiology and Hygiene. In 1946, Central Laboratory of Aviation Medicine was established, together with the Clinic and Aeromedical Commission, converted into Central Institute of Aeromedical Studies in 1947 and then, into Military Scientific Research and Experimental Institute of Aviation Medicine. In 1958 it was given the name of Air Force Institute of Aviation Medicine-in 1972-with Clinics. Simultaneously with scientific-research activity, aviation medicine developed, dealing with specifics factors affecting pilots during flights. As far otolaryngology is concerned, it deals, apart from the treatment being the domain of otolaryngologists, with histopathology of the equilibrium system and auditory organ, effects of rapid changes, barometric pressure and acceleration on human organism, the influence of weightlessness, the phenomenon of habituation and the effect of Coriolis acceleration on the equilibrium system.

Survey of hormone activities in municipal biosolids and animal manures.  

PubMed

The potential exists for natural or synthetic hormonal chemicals present in agricultural fertilizers to be transferred to adjacent aquatic environments in order to alter endocrine function in exposed wildlife. Recombinant yeast and mammalian cell line (BG1Luc4E2) assays were used to screen crude organic extracts of municipal biosolids and animal manures for estrogen-, androgen-, and progesterone receptor gene transcription activities. Of the biosolid extracts, those samples that had undergone aerobic digestion had no or minimal estrogen- and no androgen receptor gene transcription activities. In contrast, those biosolid samples that had undergone anaerobic digestion had much higher estrogen- and, for all but one site, androgen receptor gene transcription activities. Extracts prepared from animal manure samples had variable levels of androgen- and estrogen receptor gene transcription activities, which may be related to the type, sex, age, and reproductive status of the animals. The diet and treatment of animals with hormone implants also appeared to be factors influencing hormone activity in animal manure. Progesterone receptor gene transcription activity was observed for only one chicken litter sample. Overall, results of this study suggest that in vitro bioassays can be used to survey and detect hormone activity in municipal biosolids and animal manures. Furthermore, results of these assays can be used to develop practices that will minimize the potential environmental endocrine-disrupting effects of these substances. PMID:15101037

The climate impact of aviation aerosols  

NASA Astrophysics Data System (ADS)

A comprehensive general circulation model (GCM) is used to estimate the climate impact of aviation emissions of black carbon (BC) and sulfate (SO4) aerosols. Aviation BC is found not to exert significant radiative forcing impacts, when BC nucleating efficiencies in line with observations are used. Sulfate emissions from aircraft are found to alter liquid clouds at altitudes below emission (˜200 hPa); contributing to shortwave cloud brightening through enhanced liquid water path and drop number concentration in major flight corridors, particularly in the N. Atlantic. Global averaged sulfate direct and indirect effects on liquid clouds of 46 mWm-2are larger than the warming effect of aviation induced cloudiness of 16 mWm-2. The net result of including contrail cirrus and aerosol effects is a global averaged cooling of -21±11 mWm-2. These aerosol forcings should be considered with contrails in evaluating the total global impact of aviation on climate.

A case for biofuels in aviation  

SciTech Connect

In the last 15 years, the technical and the economic feasibility of biomass based fuels for general aviation piston engines has been proven. Exhaustive ground and flight tests performed at the Renewable Aviation Fuels Development Center (RAFDC) using ethanol, ethanol/methanol blends, and ETBE have proven these fuels to be superior to aviation gasoline (avgas) in all aspects of performance except range. Two series of Lycoming engines have been certified. Record flights, including a transatlantic flight on pure ethanol, were made to demonstrate the reliability of the fuel. Aerobatic demonstrations with aircraft powered by ethanol, ethanol/methanol, and ETBE were flown at major airshows around the world. the use of bio-based fuels for aviation will benefit energy security, improve the balance of trade, domestic economy, and environmental quality. The United States has the resources to supply the aviation community`s needs with a domestically produced fuel using current available technology. The adoption of a renewable fuel in place of conventional petroleum-based fuels for aviation piston and turbine engines is long overdue.

Supermassive black hole activity in the Cosmic Evolution Survey  

NASA Astrophysics Data System (ADS)

I investigate active supermassive black holes, also called active galactic nuclei (AGNs). My tool for this work is the Cosmic Evolution Survey (COSMOS), a deep multiwavelength survey over 2 deg2 of the sky. I describe the COSMOS AGN optical spectroscopy campaign, and present the largest AGN sample to date with full multiwavelength (radio, IR, optical, UV and X-ray) spectral energy distributions. Studying the COSMOS AGN sample reveals a unified model for supermassive black hole activity based on accretion rate, as shown by the following main results. (1) Classically "obscured" (Type 2) AGNs are more prevalent at higher redshifts and lower luminosities, suggesting that these objects accrete through low-level stochastic disk feeding by their hosts. (2) The presence of broad emission lines in an AGN requires a minimum accretion rate (L/LEdd > 0.01). Broad-line (Type 1) AGNs in COSMOS span a large range of accretion rates (0.01 < L/LEdd < 1), in contrast to results from previous, shallower surveys, and broad-line AGNs become more optically luminous as accretion rate increases. (3) Lineless, "optically dull" AGNs have very different SEDs than broad-line and narrow-line AGNs, with comparatively brighter X-ray emission, redder optical continua, no infrared hot dust, and stronger radio emission. While up to 2/3 of optically dull AGNs may be "normal" AGNs diluted by extranuclear host galaxy light, at least 1/3 are best described as unobscured, intrinsically weak AGNs. (4) At low accretion rates, material accreting onto an AGN changes from a thin disk to an advection-dominated flow near the black hole, resulting in very different observed properties: the broad-line region disappears, radio jets become more important, and the hot dust signature changes. In contrast to previous unification models, observations indicate that most of the narrow-line and lineless AGNs in COSMOS are best described as weakly accreting AGNs. We conclude by noting a few predictions and observational tests to further investigate our model of AGN unification by accretion rate.

A Survey of Health-Related Activities on Second Life  

PubMed Central

Background Increasingly, governments, health care agencies, companies, and private groups have chosen Second Life as part of their Web 2.0 communication strategies. Second Life offers unique design features for disseminating health information, training health professionals, and enabling patient education for both academic and commercial health behavior research. Objectives This study aimed to survey and categorize the range of health-related activities on Second Life; to examine the design attributes of the most innovative and popular sites; and to assess the potential utility of Second Life for the dissemination of health information and for health behavior change. Methods We used three separate search strategies to identify health-related sites on Second Life. The first used the application’s search engine, entering both generic and select illness-specific keywords, to seek out sites. The second identified sites through a comprehensive review of print, blog, and media sources discussing health activities on Second Life. We then visited each site and used a snowball method to identify other health sites until we reached saturation (no new health sites were identified). The content, user experience, and chief purpose of each site were tabulated as well as basic site information, including user traffic data and site size. Results We found a wide range of health-related activities on Second Life, and a diverse group of users, including organizations, groups, and individuals. For many users, Second Life activities are a part of their Web 2.0 communication strategy. The most common type of health-related site in our sample (n = 68) were those whose principle aim was patient education or to increase awareness about health issues. The second most common type of site were support sites, followed by training sites, and marketing sites. Finally, a few sites were purpose-built to conduct research in SL or to recruit participants for real-life research. Conclusions Studies show that behaviors from virtual worlds can translate to the real world. Our survey suggests that users are engaged in a range of health-related activities in Second Life which are potentially impacting real-life behaviors. Further research evaluating the impact of health-related activities on Second Life is warranted.

In-depth survey of sunspot and active region catalogs  

NASA Astrophysics Data System (ADS)

When consulting detailed photospheric catalogs for solar activity studies spanning long time intervals, solar physicists face multiple limitations in the existing catalogs: finite or fragmented time coverage, limited time overlap between catalogs and even more importantly, a mismatch in contents and conventions. In view of a study of new sunspot-based activity indices, we have conducted a comprehensive survey of existing catalogs. In a first approach, we illustrate how the information from parallel catalogs can be merged to form a much more comprehensive record of sunspot groups. For this, we use the unique Debrecen Photoheliographic Data (DPD), which is already a composite of several ground observatories and SOHO data, and the USAF/Mount Wilson catalog from the Solar Optical Observing Network (SOON). We also describe our semi-interactive cross-identification method, which was needed to match the non-overlapping solar active region nomenclature, the most critical and subtle step when working with multiple catalogs. This effort, focused here first on the last two solar cycles, should lead to a better central database collecting all available sunspot group parameters to address future solar cycle studies beyond the traditional sunspot index time series Ri.

Transport impacts on atmosphere and climate: Aviation  

NASA Astrophysics Data System (ADS)

Aviation alters the composition of the atmosphere globally and can thus drive climate change and ozone depletion. The last major international assessment of these impacts was made by the Intergovernmental Panel on Climate Change (IPCC) in 1999. Here, a comprehensive updated assessment of aviation is provided. Scientific advances since the 1999 assessment have reduced key uncertainties, sharpening the quantitative evaluation, yet the basic conclusions remain the same. The climate impact of aviation is driven by long-term impacts from CO 2 emissions and shorter-term impacts from non-CO 2 emissions and effects, which include the emissions of water vapour, particles and nitrogen oxides (NO x). The present-day radiative forcing from aviation (2005) is estimated to be 55 mW m -2 (excluding cirrus cloud enhancement), which represents some 3.5% (range 1.3-10%, 90% likelihood range) of current anthropogenic forcing, or 78 mW m -2 including cirrus cloud enhancement, representing 4.9% of current forcing (range 2-14%, 90% likelihood range). According to two SRES-compatible scenarios, future forcings may increase by factors of 3-4 over 2000 levels, in 2050. The effects of aviation emissions of CO 2 on global mean surface temperature last for many hundreds of years (in common with other sources), whilst its non-CO 2 effects on temperature last for decades. Much progress has been made in the last ten years on characterizing emissions, although major uncertainties remain over the nature of particles. Emissions of NO x result in production of ozone, a climate warming gas, and the reduction of ambient methane (a cooling effect) although the overall balance is warming, based upon current understanding. These NO x emissions from current subsonic aviation do not appear to deplete stratospheric ozone. Despite the progress made on modelling aviation's impacts on tropospheric chemistry, there remains a significant spread in model results. The knowledge of aviation's impacts on cloudiness has also improved: a limited number of studies have demonstrated an increase in cirrus cloud attributable to aviation although the magnitude varies: however, these trend analyses may be impacted by satellite artefacts. The effect of aviation particles on clouds (with and without contrails) may give rise to either a positive forcing or a negative forcing: the modelling and the underlying processes are highly uncertain, although the overall effect of contrails and enhanced cloudiness is considered to be a positive forcing and could be substantial, compared with other effects. The debate over quantification of aviation impacts has also progressed towards studying potential mitigation and the technological and atmospheric tradeoffs. Current studies are still relatively immature and more work is required to determine optimal technological development paths, which is an aspect that atmospheric science has much to contribute. In terms of alternative fuels, liquid hydrogen represents a possibility and may reduce some of aviation's impacts on climate if the fuel is produced in a carbon-neutral way: such fuel is unlikely to be utilized until a 'hydrogen economy' develops. The introduction of biofuels as a means of reducing CO 2 impacts represents a future possibility. However, even over and above land-use concerns and greenhouse gas budget issues, aviation fuels require strict adherence to safety standards and thus require extra processing compared with biofuels destined for other sectors, where the uptake of such fuel may be more beneficial in the first instance.

Cosmic radiation in commercial aviation.  

PubMed

This paper reviews the current knowledge of cosmic radiation and its applicability to commercial aviation. Galactic cosmic radiation emanates from outside the solar system, while occasionally a disturbance in the suns' atmosphere leads to a surge in radiation particles. Protection is provided by the suns' magnetic field, the earths' magnetic field, and the earths' atmosphere. Dose rates are dependent on the altitude, the geomagnetic latitude and the solar cycle. For occupational exposure to ionising radiation, which includes aircrew, the International Commission on Radiological Protection recommends maximum mean body effective dose limits of 20mSv/yr (averaged over 5 years, with a maximum in any 1 year of 50mSv). Radiation doses can be measured during flight or may be calculated using a computer-modelling program such as CARI, EPCARD, SIEVERT or PCAIRE. Mean ambient equivalent dose rates are consistently reported in the region of 4-5microSv/h for long-haul pilots and 1-3microSv/h for short-haul, giving an annual mean effective exposure of the order 2-3mSv for long-haul and 1-2mSv for short-haul pilots. Epidemiological studies of flight crew have not shown conclusive evidence for any increase in cancer mortality or cancer incidence directly attributable to ionising radiation exposure. Whilst there is no level of radiation exposure below which effects do not occur, current evidence indicates that the probability of airline crew or passengers suffering adverse health effects as a result of exposure to cosmic radiation is very low.

Carbon dioxide hazards in general aviation.  

PubMed

There are numerous reports of carbon dioxide fire extinguishers or significant loads of dry ice causing actual or potential carbon dioxide intoxication leading to accidents or incidents, both in the military and in the airlines. To evaluate the significance of the problem in general aviation, dry ice sublimation reported in literature and measured sublimation was theoretically applied to general aviation aircraft, and carbon dioxide from fire extinguishers was measured, both in static and flight condition. The results indicate that the use of carbon dioxide fire extinguishers or the transportation under some conditions of dry ice could produce levels which could cause severe anxiety due to respiratory stimulation or actually produce pilot impairment and contribute to or cause accidents.

A Narrow-band Survey of Protostellar Shock Activity  

NASA Astrophysics Data System (ADS)

Energetic outflows are a ubiquitous signpost of star formation, observed in young stars of all masses. In studies of the early stages of star formation, we strive both to understand the mechanical and chemical properties of gas within an outflow, and to characterize outflow interactions with the dense clouds in which they are embedded. To develop a complete model of the interactions between protostar, outflow, and natal molecular cloud, surveys of entire star forming clouds as well as detailed studies of individual outflows are required. We have conducted a near-infrared protostellar shock survey of 35 star-forming regions in the Galaxy, including both isolated, individual outflows as well as larger molecular clouds containing multiple outflows. We imaged these regions in near-infrared narrow-band emission lines of molecular hydrogen, [FeII], and Paschen beta with the refurbished 2MASS camera on the Steward Observatory 61-inch Kuiper telescope. In addition, we have obtained moderate resolution (R=3500) near-infrared spectra (using TripleSpec at the Apache Point Observatory) for some of the individual outflows. We use the complementary near-infrared spectroscopic and imaging data to characterize the physical properties of each outflow, including excitation temperatures, emission line velocities, and energetics, and to describe the feedback these outflows may have on their natal clouds.

A survey of KHI activity at the magnetopause  

NASA Astrophysics Data System (ADS)

The Kelvin Helmholtz Instability can drive waves at the magnetopause. These waves can grow to form rolled up vortices and facilitate transfer of plasma into the magnetosphere. Using a method previously presented by Hasegawa et al., 2006, we present a survey of all Double Star 1 magnetopause crossings that display characteristics of rolled up vortices, using a combination of ion and magnetic field measurements. Candidate events were identified as quasi-periodic fluctuations in the transition region between magnetospheric and magnetosheath like plasma accompanied by a persistent northward oriented magnetic field with low shear across the boundary. We find a dawn dusk asymmetry and difference in local time occurrence of these events. This work is being carried out as part of an International Space Science Institute (ISSI) working group examining multi-spacecraft conjunctions and their utility in examining the behaviour of the dayside magnetopause and flanks under various driving conditions.

ALLStars: Overcoming Multi-Survey Selection Bias using Crowd-Sourced Active Learning  

NASA Astrophysics Data System (ADS)

Developing a multi-survey time-series classifier presents several challenges. One problem is overcoming the sample selection bias which arises when the instruments or observing cadences differ between the training and testing datasets. In this case, the probabilistic distributions characterizing the sources in the training survey dataset differ from the source distributions in the other survey, resulting in poor results when a classifier is naively applied. To resolve this, we have developed the ALLStars active learning framework which allows us to bootstrap a classifier onto a new survey using a small set of optimally chosen sources which are then presented to users for manual classification. Several iterations of this crowd-sourcing process results in a significantly improved classifier. Using this procedure, we have built a variable star light-curve classifier using OGLE, Hipparcos, and ASAS survey data.

A Survey of Physical Activity Levels of Certified Athletic Trainers.  

PubMed

OBJECTIVE: To determine the self-reported physical activities of certified athletic trainers (ATCs), both at work and at leisure. DESIGN AND SETTING: We used the Baecke Questionnaire of Habitual Physical Activity and also asked for demographic information, including employment setting, years of experience, education level, and position. SUBJECTS: The questionnaire was sent to 1200 randomly selected ATCs in the Mid-America Athletic Trainers' Association; the return rate was 53%. MEASUREMENTS: We used means, standard deviations, and ranges to describe the age, total fitness index, work, and leisure and sport indexes of men and women subjects. Independent t tests were used to compare the mean total activity index between men and women within this study and with previous studies. We examined differences in activity indexes by employment setting, position, and age with one-way analysis of variance and Fisher pairwise comparison tests. Two-way chi(2) analysis was used to determine the relationship between activity level and employment setting and position. Statistical significance was set at P =.05 for all analyses. RESULTS: Certified athletic trainers who work in a clinical setting had the highest mean total activity score at 9.1 points. Clinic ATCs scored significantly higher than high school ATCs and college ATCs. When compared by position, there were no significant differences among the mean total activity indexes; however, the mean work index of program directors was significantly lower than all other positions and the mean work index of high school and clinic ATCs was significantly higher than all other employment settings. CONCLUSIONS: Female ATCs scored significantly higher in total activity levels on the Baecke Questionnaire than their male counterparts. This is in contrast to the general population, investigated by other authors, in which men scored significantly higher than women on the same scale. Additionally, we compared the total activity levels by age, position, and employment setting. There was a significant difference by position only in the work index. The mean total index activity of the over-36-years-old group was significantly lower than all other age categories. There was no significant difference in mean total activity levels by employment setting. PMID:12937586

Evaluating the Impacts of Aviation on Climate Change  

NASA Astrophysics Data System (ADS)

Aviation is an integral part of the global economic and transportation systems. In fact, aviation expansion outpaces the economic growth. Projections indicate that over the next 2 decades, the demand for aviation could grow to about 3 times its present level. This projected growth will likely result in higher aviation emissions and associated impacts on the environment and on human health and welfare, depending upon a variety of factors (such as the size and mix of the operational fleet necessary to meet the stated demand, as well as mitigation steps that could include new technological advances, more efficient operational procedures, market-based options, or regulatory intervention). Nonetheless, it is critical to balance the economic benefits of air travel with environmental concerns associated with this projected aviation growth.

Agricultural aviation medicine in the Soviet Union.  

PubMed

The Soviet Union has developed one of the world's most sophisticated civil aviation medicine programs. The program gives specific attention to aerial application operations and includes special preflight pilot medical examinations, aircraft with specialized protective airflow systems for the pilots, minimum flight altitude spraying limit of 5 m, and the use of a "chemical log book" by each pilot in addition to the flight log book. These and additional steps--i.e. limiting a pilot's daily agricultural flights to 4-6 h--have led to a reported USSR agricultural aviation annual accident rate near zero. The Soviet workhorse aircraft, the Antonov AN-2, can serve multipurpose roles since, when not used for application flights, it can be rapidly converted to executive, courier, cargo, or air taxi, or air ambulance use. A new, single-engine turbojet biplane, the Polish M-15, is undergoing evaluation in the Soviet Union as a replacement for the AN-2. Countries with very high agricultural aircraft accident rates may wish to study the Soviet approach, especially the use by the pilot of a chemical log book. PMID:6248014

Comparison of global 3-D aviation emissions datasets  

NASA Astrophysics Data System (ADS)

Aviation emissions are unique from other transportation emissions, e.g., from road transportation and shipping, in that they occur at higher altitudes as well as at the surface. Aviation emissions of carbon dioxide, soot, and water vapor have direct radiative impacts on the Earth's climate system while emissions of nitrogen oxides (NOx), sulfur oxides, carbon monoxide (CO), and hydrocarbons (HC) impact air quality and climate through their effects on ozone, methane, and clouds. The most accurate estimates of the impact of aviation on air quality and climate utilize three-dimensional chemistry-climate models and gridded four dimensional (space and time) aviation emissions datasets. We compare five available aviation emissions datasets currently and historically used to evaluate the impact of aviation on climate and air quality: NASA-Boeing 1992, NASA-Boeing 1999, QUANTIFY 2000, Aero2k 2002, and AEDT 2006 and aviation fuel usage estimates from the International Energy Agency. Roughly 90% of all aviation emissions are in the Northern Hemisphere and nearly 60% of all fuelburn and NOx emissions occur at cruise altitudes in the Northern Hemisphere. While these datasets were created by independent methods and are thus not strictly suitable for analyzing trends they suggest that commercial aviation fuelburn and NOx emissions increased over the last two decades while HC emissions likely decreased and CO emissions did not change significantly. The bottom-up estimates compared here are consistently lower than International Energy Agency fuelburn statistics although the gap is significantly lower in the more recent datasets. Overall the emissions distributions are quite similar for fuelburn and NOx while for CO and HC there are relatively larger differences. There are however some distinct differences in the altitude distribution of emissions in certain regions for the Aero2k dataset.

Aeromedical examiners (AMEs) do not necessarily treat depressive patients frequently, so they often consult psychiatrists; however, psychiatrists are rarely familiar with aviator treatment protocols. U.S., Canadian, and Australian regulations allow several choices among antidepressant drugs for flying pilots recovering from an MDE. Symptom stability times before the possible return to flying duties vary from 4 wk to 12 mo. So far European regulations have not allowed antidepressants, but the situation may change. PMID:22946357

Federal Aviation Administration telecommunications strategic plan  

NASA Astrophysics Data System (ADS)

The plan was developed to ensure that the high levels of telecommunications services required to support all aspects of National Airspace System (NAS) operational and Federal Aviation Administration (FAA) administrative requirements are available at the right time, in the right place, and at the lowest possible cost. The plan is composed of six major sections: Introductions, Goals and Objectives; Requirements; Optimum Communications Approach; Operations, Administration, and Maintenance (OA&M); and Transition Strategy. It provides a detailed look at the strategic planning process used, and documents the specific current and future FAA telecommunications requirements. It examines the baseline telecommunications architecture and significant technology trends. It also describes the FAA optimum communications approach, and discusses the need for an integrated approach to OA&M. Finally, the plan presents a detailed transition strategy.

Federal Aviation Administration retained savings program proposal  

SciTech Connect

Federal legislation allows federal agencies to retain up to 50% of the savings associated with implementing energy efficiency and water conservation measures and practices. Given budget pressures to reduce expenditures, the use of retained savings to fund additional projects represents a source of funds outside of the traditional budget cycle. The Southwest Region Federal Aviation Administration (FAA) has tasked Pacific Northwest National Laboratory (PNNL) to develop a model retained savings program for Southwest Region FAA use and as a prototype for consideration by the FAA. PNNL recommends the following steps be taken in developing a Southwest Region FAA retained savings program: Establish a retained savings mechanism. Determine the level at which the retained savings should be consolidated into a fund. The preliminary recommendation is to establish a revolving efficiency loan fund at the regional level. Such a mechanism allows some consolidation of savings to fund larger projects, while maintaining a sense of facility ownership in that the funds will remain within the region.

CAPPS II: the foundation of aviation security?  

PubMed

A new computer system is being developed to classify U.S. air travelers by the degree of terrorist threat they might pose. Reports indicate that the system--called CAPPS II--would use large amounts of information about each passenger, perhaps including such personal details as his or her magazine-subscription behavior. We argue that what is publicly known about CAPPS II raises questions about how substantially the system would improve aviation security. We discuss conditions under which CAPPS II could yield safety benefits, but suggest that it might be more prudent to view the system as one component of future security arrangements rather than the centerpiece of these arrangements.

A MID-INFRARED CENSUS OF STAR FORMATION ACTIVITY IN BOLOCAM GALACTIC PLANE SURVEY SOURCES  

SciTech Connect

We present the results of a search for mid-infrared signs of star formation activity in the 1.1 mm sources in the Bolocam Galactic Plane Survey (BGPS). We have correlated the BGPS catalog with available mid-IR Galactic plane catalogs based on the Spitzer Space Telescope GLIMPSE legacy survey and the Midcourse Space Experiment (MSX) Galactic plane survey. We find that 44% (3712 of 8358) of the BGPS sources contain at least one mid-IR source, including 2457 of 5067 (49%) within the area where all surveys overlap (10 deg. < l < 65 deg.). Accounting for chance alignments between the BGPS and mid-IR sources, we conservatively estimate that 20% of the BPGS sources within the area where all surveys overlap show signs of active star formation. We separate the BGPS sources into four groups based on their probability of star formation activity. Extended Green Objects and Red MSX Sources make up the highest probability group, while the lowest probability group is comprised of 'starless' BGPS sources which were not matched to any mid-IR sources. The mean 1.1 mm flux of each group increases with increasing probability of active star formation. We also find that the 'starless' BGPS sources are the most compact, while the sources with the highest probability of star formation activity are on average more extended with large skirts of emission. A subsample of 280 BGPS sources with known distances demonstrates that mass and mean H{sub 2} column density also increase with probability of star formation activity.

Purpose of the work was to examine the acoustic and work environment of air forces personnel, to look for the specific effects of aviation noise on human organism, and to put out evidence-based guidelines for protection. On-site acoustics measurements, hygiene inspection of labor conditions and analysis of disease incidence including review of clinical investigations results were carried out. It was demonstrated that the aviation noise spectrum spreads to the sound and infrasound high-frequency bands referring the aviation personnel environment to class 3.2-4 of harmful and hazardous occupations. The combination of noise and infrasound provokes specific (occupational) and nonspecific diseases. Choice of the protectors should be made with consideration of specifics of the biological effects of aviation noise. PMID:22953534

Durations and Domains of Daily Aerobic Activity: Evidence from the 2010 Canadian Time-Use Survey.  

PubMed

BACKGROUND: This study employs national time-diary data to evaluate how much aerobic activity Canadians engage in on a daily basis, how that activity is apportioned by activity domain, and how sub-groups within the population vary in their aerobic attainment. METHODS: The study employs time-use data from the 2010 General Social Survey of Canada, for 15,390 respondents aged 15 and older. To estimate effort levels, the authors harmonized survey codes with those in the Compendium of Physical Activities. Aerobic activity was defined as moderate or vigorous effort at 3.5 Metabolic Equivalent of Task (MET) or higher. RESULTS: Among the four activity domains, aerobic participation is highest in leisure activities, followed by chores, paid work, and active transportation (AT). Only a minority (42%) of respondents recorded at least 20 mins/day of aerobic activity. Aerobic totals were particularly low for women and those in poor or fair health, and low for students, 15-24 year-olds, and those residing in Quebec, Ontario, and larger cities. CONCLUSIONS: The majority of Canadian adults are failing to meet recommended aerobic activity levels. However, there is considerable opportunity to increase aerobic participation for some groups, particularly women and young adults, especially in the leisure and AT domains. PMID:23676583

Relationship between multimorbidity and physical activity: Secondary analysis from the Quebec health survey  

PubMed Central

Background Abundant literature supports the beneficial effects of physical activity for improving health of people with chronic diseases. The relationship between multimorbidity and physical activity levels, however, has been little evaluated. The purpose of the current exploratory study was to examine the relationship between a) multimorbidity and physical activity levels, and b) long-term limitations on activity, self-rated general health, psychological distress, and physical activity levels for each sex in adults, after age, education, income, and employment factors were controlled for. Methods Data from the Quebec Health Survey 1998 were used. The sample included 16,782 adults 18–69 yr of age. Independent variables were multimorbidity, long-term limitations on activity, self-rated general health, and psychological distress. The dependent variable was physical activity levels. Links between the independent and dependent variables were assessed separately for men and women with multinomial regressions while accounting for the survey sampling design and household clustering. Results About 46% of the participants were men. Multimorbidity was not associated with physical activity levels for either men or women. Men and women with long-term limitations on activity and with poor-to-average self-rated general health were less likely to be physically active. No relationship between psychological distress and physical activity was found for men. Women with high levels of psychological distress were less likely to be physically active. Conclusion Multimorbidity was not associated with physical activity levels in either sex, when age, education, income, and employment factors were controlled for. Long-term limitations on activity and poor-to-average self-rated general health seem related to a reduction in physical activity levels for both sexes, whereas psychological distress was associated with a reduction in physical activity levels only among women. Longitudinal studies using a comorbidity or multimorbidity index to account for severity of the chronic diseases are needed to replicate the results of this exploratory study.

Seismic Vulnerability Evaluations Within The Structural And Functional Survey Activities Of The COM Bases In Italy  

SciTech Connect

The paper describes technical and functional surveys on COM buildings (Mixed Operative Centre). This activity started since 2005, with the contribution of both Italian Civil Protection Department and the Regions involved. The project aims to evaluate the efficiency of COM buildings, checking not only structural, architectonic and functional characteristics but also paying attention to surrounding real estate vulnerability, road network, railways, harbours, airports, area morphological and hydro-geological characteristics, hazardous activities, etc. The first survey was performed in eastern Sicily, before the European Civil Protection Exercise 'EUROSOT 2005'. Then, since 2006, a new survey campaign started in Abruzzo, Molise, Calabria and Puglia Regions. The more important issue of the activity was the vulnerability assessment. So this paper deals with a more refined vulnerability evaluation technique by means of the SAVE methodology, developed in the 1st task of SAVE project within the GNDT-DPC programme 2000-2002 (Zuccaro, 2005); the SAVE methodology has been already successfully employed in previous studies (i.e. school buildings intervention programme at national scale; list of strategic public buildings in Campania, Sicilia and Basilicata). In this paper, data elaborated by SAVE methodology are compared with expert evaluations derived from the direct inspections on COM buildings. This represents a useful exercise for the improvement either of the survey forms or of the methodology for the quick assessment of the vulnerability.

Contact lenses in aviation: the Marine Corps experience.  

PubMed

In an attempt to limit safety and health risks, Naval Aeromedical Policy has historically prohibited the use of contact lenses in the Navy and Marine Corps Class 1 Aviation Personnel (pilots), approximately 18% of whom require spectacles. Recent technological advancements have rendered spectacles functionally incompatible with some mission-essential masks, goggles, and imaging devices, thus forcing a re-examination of existing policy. Recent U.S. Army and U.S. Air Force aviation studies favorably compare the performance of contact lenses to spectacles. In order to test the application of contact lenses in the unique U.S. Marine Corps aviation environment, encompassing shipboard, land-based, and forwardly-deployed units, 90 aviation personnel assigned to several deploying squadrons were evaluated for contact lenses; flex-wear disposable lenses were the primary modality of choice. Of the subjects, 68 (73%) were successfully fit and continued contact lens wear for a period of 16 months. Safety and health were not compromised, and job performance was favorably affected. No cases of ulcerative keratitis or vision loss were reported. The first U.S. Marine Corps aviation contact lens study supports the growing belief that contact lenses can be safely and effectively applied in the critical and hazardous aviation environment.

Methodological Innovations in Collecting Spending Data: The HRS Consumption and Activities Mail Survey.  

PubMed

It has traditionally been believed that collecting survey measures of total spending necessarily involved asking a large number of questions, too many for inclusion of a comprehensive spending measure in a general-purpose survey. In this paper we report on a supplemental survey to the Health and Retirement Study that took up this challenge. We discuss issues that arise designing a survey module to collect spending data with strict time constraints, describe how the implementation in the Consumption and Activities Mail Survey (CAMS) played out, and elicit anomalies that more detailed analysis of data quality revealed. We report how we addressed some of these anomalies in subsequent waves of CAMS. Other anomalies required conducting additional randomized experiments to find what explains the observed patterns. The results highlight the tension between asking about spending using a long time frame, which exacerbates recall bias, versus using a short time frame, which risks relying on an unrepresentative snapshot of a household's spending to proxy the total for the last 12 months. An important complicating factor in deciding which goods should be put into which time frames is that there is substantial heterogeneity in the frequency of spending across households even for the same category of spending.

Investigating the media power of a population health monitoring survey: case study of the NSW Schools Physical Activity and Nutrition Survey (SPANS).  

PubMed

OBJECTIVE : To examine the extent and nature of news coverage of a government-funded population monitoring survey of children and the potential implications of this coverage for public health advocacy. METHODS : Case study of the NSW Schools Physical Activity and Nutrition Survey (SPANS), a population monitoring survey of school-aged children's weight and weight-related behaviours, conducted in 1997, 2004 and 2010. Printed news items from all Australian newspapers between January 1997 and December 2011 mentioning the survey findings were identified from the Factiva database and a descriptive analysis of the content conducted. RESULTS : Overall, 144 news items were identified. The news angles focused mainly on physical activity/sedentary behaviour; overweight/obesity and nutrition; however these angles changed between 1997 and 2011, with angles focused on physical activity/sedentary behaviour increasing, compared with overweight/obesity and nutrition angles (p=0.001). Responsibility for obesity and weight-related behaviours was most frequently assigned to parents and food marketing, and the most common solutions were policy strategies and parental/child education and support. CONCLUSIONS : Population health surveys are newsworthy and when coupled with strategic dissemination, media can contribute to communicating health issues and interpreting findings in ways that are relevant for consumers, policy makers and stakeholders. Implications : This case study emphasises the news value of government-funded population surveys, while providing a cautionary note about media focus on individual studies rather than a larger body of research evidence.

Completion of a Large Survey of Activity in Nearby G Dwarfs  

NASA Astrophysics Data System (ADS)

This program will complete a survey of activity in ~5,000 solar- type stars within 60 pc. By ``solar-type'' we mean about F8V to K2V (the sample is defined by B-V colors from Hipparcos). Activity is measured from the cores of the Ca II H and K lines. We have already observed ~3,000 stars above -40° declination at Kitt Peak and about 800 stars below -26° in an earlier effort at CTIO. This proposal is for mop-up in the northern portions, and for the first semester for southern stars using the Hipparcos-defined sample (the earlier sample was less well defined and not volume-limited, although portions of it are still valid). This survey has three purposes. First, we identify interesting (i.e., highly active) stars worthy of further study. Some of these turn out to be pre-main sequence stars which are not associated with known regions of star formation, and their existence is difficult to explain. Second, we provide an extensive context into which to place solar and stellar activity in a statistical sense. Finally, the survey will provide metallicities of good systematic quality for studying properties of our Galactic neighborhood. The information we produce will become part of an effort to fully characterize the nearby stars.

Activities of the U.S. Geological Survey Water-Resources Division in North Carolina, 1986  

USGS Publications Warehouse

Water resources programs conducted by the U.S. Geological Survey in the state of North Carolina during 1985 and proposed programs for 1986 are described. This is the first in a series of biennial progress reports on Survey activities in the state. Activities such as gathering, interpreting and publishing hydrologic data and scientific information in support of state and local water resources planning, management, and regulatory programs are presented. The water resources programs described are funded through cooperative agreements with state and local agencies and through special agreements with other federal agencies. Cooperative programs are reviewed annually to insure that state, local and national priorities are being met. Groundwater withdrawals are estimated to have produced water level declines of 150 ft and more for large areas of the northeast and central Coastal Plain. Future demands for water quality and quantity are discussed.

Global Turbulence Decision Support for Aviation  

NASA Astrophysics Data System (ADS)

Turbulence is widely recognized as the leading cause of injuries to flight attendants and passengers on commercial air carriers, yet legacy decision support products such as SIGMETs and SIGWX charts provide relatively low spatial- and temporal-resolution assessments and forecasts of turbulence, with limited usefulness for strategic planning and tactical turbulence avoidance. A new effort is underway to develop an automated, rapid-update, gridded global turbulence diagnosis and forecast system that addresses upper-level clear-air turbulence, mountain-wave turbulence, and convectively-induced turbulence. This NASA-funded effort, modeled on the U.S. Federal Aviation Administration's Graphical Turbulence Guidance (GTG) and GTG Nowcast systems, employs NCEP Global Forecast System (GFS) model output and data from NASA and operational satellites to produce quantitative turbulence nowcasts and forecasts. A convective nowcast element based on GFS forecasts and satellite data provides a basis for diagnosing convective turbulence. An operational prototype "Global GTG” system has been running in real-time at the U.S. National Center for Atmospheric Research since the spring of 2009. Initial verification based on data from TRMM, Cloudsat and MODIS (for the convection nowcasting) and AIREPs and AMDAR data (for turbulence) are presented. This product aims to provide the "single authoritative source” for global turbulence information for the U.S. Next Generation Air Transportation System.

Airline History: The History of Commercial Aviation  

NSDL National Science Digital Library

Designed and maintained by Sarah Ward, a former commercial pilot, this site offers essays about almost every major airline, both contemporary and historical. A complete alphabetical list runs from the ABA Swedish Air Lines all the way to ZAS Airline of Egypt. Each profile gives details about the types of planes used by each airline; what type of business they conducted (and where); and numerous photographs of the planes, many taken by Ms. Ward. Along with the airline profiles, another section of the site titled Aircraft by Decade offers basic statistics about different plane models and types introduced during every decade of the 20th century. Special features of the site include a photographic tribute to the planes that travelers might have seen as they traversed through London's airports in the 1960s, 1970s, and 1980s. Ms. Ward has taken a great deal of care in compiling the material on the site (along with the help of contributors), and the material here will be a joy for aviation fans and visitors interested in knowing a bit more about the history of different airlines.

Experimental characterization of aviation-fuel cavitation  

NASA Astrophysics Data System (ADS)

The results of an experimental investigation of the gaseous cavitation of JP-8 aviation fuel in a converging-diverging nozzle are presented. Fuel cavitation is experimentally characterized by high-speed digital imaging, static pressure distributions, and nonintrusive void fraction and bubble velocity measurements. For comparative purposes, experiments were performed using distilled water and dodecane for the same nozzle and nozzle pressure ratios. Dodecane, the largest component of JP-8 by weight, served as its single-component surrogate. For each working fluid, the experiments examined two different flow regimes: an initially single-phase liquid flow in which no cavitation occurred and another that evolved into two-phase cavitating flow. Additional experiments were performed to study the effect of air bubbles injected into either water or JP-8 at the nozzle inlet. For a sufficiently low range of imposed back pressures, gaseous cavitation led to choked flow for each working fluid. The character of the cavitation in the three fluids was different. These differences are highlighted and plausible mechanisms responsible for the observed behavior are discussed.

Factors influencing adolescent sexual activity in Nigeria: analysis of the 1990 Demographic and Health Survey.  

PubMed

Unmarried adolescents in Nigeria have become more sexually active over the past decade. Data are available from Nigeria's 1990 National Demographic and Health Survey for 1678 unmarried female adolescents aged 15-19 years. 1104 of these young women were unmarried at the time of the survey. 26.4% of the unmarried women were sexually active at the time of the survey, 67.5% of whom had unprotected coitus. Analysis of the survey data found that adolescents became 1.5 times more likely to be sexually active as they moved from one age to another. Adolescents with an average knowledge of contraception were twelve times more likely to be sexually active than those with no knowledge. The author notes with regard to this finding that engaging in sexual intercourse is more likely to encourage a search for information on contraceptives rather than the reverse. Women with average knowledge had a lower probability of contraceptive use than those with a low level of knowledge. Knowledge of contraceptives is a necessary but not sufficient condition for use, especially given the experimental and sporadic sex lives of growing adolescents. Friends were the preferred source of information on contraceptive use. Finally, educational status, residence, and region were found to be only indirectly associated with sexual intercourse. In the interest of developing positive attitudes among adolescents toward contraceptive use, the author recommends educating parents through the mass media and at Parents Teachers Association meetings on the realities of adolescence and the need to provide their children with information on sexuality, having health educators to work with teachers in schools to develop curricula and skills to convey family life and sex education to children and adolescents, recruiting and training adolescent peer educators on family life and sex education, and establishing adolescent units within existing family planning clinics across the country. A strong commitment to program success is needed from the government and health workers. PMID:12288935

Health physics and aviation: solar cycle 23 (1996-2008).  

PubMed

We continue our description of the scientific and professional activities that were initiated by the classification of airline flight crewmembers as occupational radiation workers in 1994, specifically looking at the period between 1996 and 2008. During this period, radiation measurement programs were conducted on numerous commercial aircraft flights. Epidemiological studies have looked at the incidence of cancer in pilots and flight attendants, with mixed conclusions. The Federal Aviation Administration (FAA) released revised versions of its CARI software, the computer program designed to evaluate radiation exposures received on user-defined flight plans. Additional dose-evaluation programs have been made available by other entities. In May 2000, member states of the European Union (EU) adopted regulations that apply to the air carriers in all twenty-seven nations requiring education on health risks of in-flight radiation as well as dose assessment for all EU flight crewmembers. The National Oceanic and Atmospheric Administration (NOAA) revised its classification scheme for space weather events including radiation-producing solar storms. In 2005, the FAA created a Solar Particle Alert system to warn aircraft of high radiation levels caused by significant events of this type. There is now an early-warning system for potentially harmful solar particle events. This new system depends on the earlier arrival time of relativistic electrons compared with the heavier particulate radiation. PMID:19276706

From aviation to medicine: applying concepts of aviation safety to risk management in ambulatory care.  

PubMed

The development of a medical risk management programme based on the aviation safety approach and its implementation in a large ambulatory healthcare organisation is described. The following key safety principles were applied: (1). errors inevitably occur and usually derive from faulty system design, not from negligence; (2). accident prevention should be an ongoing process based on open and full reporting; (3). major accidents are only the "tip of the iceberg" of processes that indicate possibilities for organisational learning. Reporting physicians were granted immunity, which encouraged open reporting of errors. A telephone "hotline" served the medical staff for direct reporting and receipt of emotional support and medical guidance. Any adverse event which had learning potential was debriefed, while focusing on the human cause of error within a systemic context. Specific recommendations were formulated to rectify processes conducive to error when failures were identified. During the first 5 years of implementation, the aviation safety concept and tools were successfully adapted to ambulatory care, fostering a culture of greater concern for patient safety through risk management while providing support to the medical staff.

American Time Use Survey: Sleep Time and Its Relationship to Waking Activities  

PubMed Central

Study Objectives: To gain some insight into how various behavioral (lifestyle) factors influence sleep duration, by investigation of the relationship of sleep time to waking activities using the American Time Use Survey (ATUS). Design: Cross-sectional data from ATUS, an annual telephone survey of a population sample of US citizens who are interviewed regarding how they spent their time during a 24-hour period between 04:00 on the previous day and 04:00 on the interview day. Participants: Data were pooled from the 2003, 2004, and 2005 ATUS databases involving N=47,731 respondents older than 14 years of age. Interventions: N/A Results: Adjusted multiple linear regression models showed that the largest reciprocal relationship to sleep was found for work time, followed by travel time, which included commute time. Only shorter than average sleepers (<7.5 h) spent more time socializing, relaxing, and engaging in leisure activities, while both short (<5.5 h) and long sleepers (?8.5 h) watched more TV than the average sleeper. The extent to which sleep time was exchanged for waking activities was also shown to depend on age and gender. Sleep time was minimal while work time was maximal in the age group 45–54 yr, and sleep time increased both with lower and higher age. Conclusions: Work time, travel time, and time for socializing, relaxing, and leisure are the primary activities reciprocally related to sleep time among Americans. These activities may be confounding the frequently observed association between short and long sleep on one hand and morbidity and mortality on the other hand and should be controlled for in future studies.

Louis H. Bauer and the origins of civil aviation medicine.  

PubMed

With the passage of the Air Commerce Act in May 1926, civil aviation safety became a federal responsibility under the Department of Commerce (DoC). In November of that year, Louis Hopewell Bauer (1888-1964) became the DoC's first Aviation Medical Director. After earning his medical degree at the Harvard School of Medicine in 1912, Bauer joined the U.S. Army Medical Corps, where he helped develop the role of the military flight surgeon and then served as director of the Army's School of Aviation Medicine. Upon taking the federal position, he undertook to define medical standards and examination frequencies for civilian pilots and identifiy disqualifying conditions that could compromise a pilot's ability to operate an aircraft safely. Bauer also personally selected 57 private physicians (soon to be known as Aviation Medical Examiners) distributed across the country to give medical examinations for pilot licenses. Bauer subsequently played a leading role in organizing the Aviation Medical Association in 1929. PMID:23316548

The Use of CT for Screening: A National Survey of Radiologists' Activities and Attitudes1  

PubMed Central

Purpose To investigate the activities, motivations, and attitudes of radiologists regarding specific computed tomographic (CT) screening examinations by using a survey. Materials and Methods All study activities were approved by the institutional review board. A self-administered, mailed survey was used to collect data on the practices and attitudes of U.S. radiologists regarding three CT screening tests—coronary artery calcium scoring (CACS), lung cancer screening CT, and whole-body screening CT. The survey was sent to 1000 diagnostic radiologists who were randomly sampled from the American Medical Association Physician Master-file. Results A total of 398 (41.4%) of 961 eligible radiologists completed the survey. Among respondents, 33.6% reported reading CT screening studies, the most common being CACS (26.7%), followed by lung screening (19.2%) and whole-body screening (9.5%). Among respondents, 34.1% supported CACS and 29.9% supported lung CT screening for particular patients, while 1.9% supported whole-body CT screening. The most common reasons reported for reading CT screening studies were responses to requests from physicians (83.3%) or patients (75.0%), while fewer (40.8%) cited patient benefit from screening as a reason. Conclusion A substantial proportion of a nationally representative sample of radiologists in the United States reads CT screening studies of the heart, lungs, and whole body and holds favorable attitudes toward CACS and lung CT screening. These attitudes may allow for the premature diffusion of new screening tests into practice before higher-level evidence demonstrates their benefits for population mortality.

Insights on Volcanic Activity - Self-Potential and Gravity surveys of Masaya volcano  

NASA Astrophysics Data System (ADS)

For more than ten years, the activity of Masaya volcano, Nicaragua, has been surveyed annually in order to characterize the long term mass/density variations within the shallow magma chamber. However, the injection of new magma is a rapid process, requiring only several hours or days. Other cyclical short period phenomena may be present (e.g., hydrothermal systems) and responsible for noise in the measured signal during a typical dynamic gravity survey. In order to determine the origin and importance of this noise and fully characterize any short period variations, a continuous gravity survey was made from February 16, 2006 to March 12, 2006 in the summit crater of Masaya. During this period, a short term of gravity variation of 60 ?Gal was measured with a wavelength of 20 hours. Hydrothermal systems, which may or may not be well developed, are directly related to heat, gas and fluids coming from the shallow magma chamber and plumbing system. Others sources of fluids are rainfall and the local aquifer, notably at the caldera lake, Laguna Masaya. Movement of hydrothermal fluids, which will generate self-potential (SP) signals, are directly influenced by superficial dyke injection and fluctuations of magma in the shallow plumbing system. The depth and movement of large fluid cells can be localized by self- potential data when processed by continuous wavelet transform. To characterize the shape and position of the hydrothermal system on the Masaya volcano, several SP profiles were made in conjunction with the continuous gravity survey. The SP data from around the summit pit craters were processed by continuous wavelet transform to localize the main large cell of hydrothermal fluid and determine the effects of the hydrothermal fluids on the continuous gravity measurements. The combination of SP and continuous gravity can give insight into short and medium term variations in magmatic activity.

Vasodilation associated with supplement use: potential concern for military aviators.  

PubMed

Military aviators are exposed to high G environments while performing certain tactical aircraft maneuvers. G forces endured during such maneuvering have been shown to reduce mean arterial blood pressure (MAP) at eye level by 22 mmHg for every G endured, leaving the average aviator with a resting G tolerance of approximately 5 to 5.5 G before losing consciousness. Many sports performance supplements on the market today contain compounds that are boasted to increase vascularity and reduce muscle recovery time. Usage of such supplements has demonstrated a reduction of MAP by as much as 16 mmHg after 1 h of dosing and could potentially lower one's G tolerance by 14%. Military aviators should proceed on the side of caution due to the potential threats that exist with consuming such products until a formal study can be conducted to investigate this matter further.

Audio-visual situational awareness for general aviation pilots  

NASA Astrophysics Data System (ADS)

Weather is one of the major causes of general aviation accidents. One possible cause is that the pilot may not absorb and retain all the weather information she is required to review prior to flight. A second cause is the inadequacy of in-flight weather updates: pilots are limited to verbal updates via aircraft radio contact with a ground-based weather specialist. We propose weather visualization and interaction methods tailored for general aviation pilots to improve understanding of pre-flight weather data and improve in-flight weather updates. Our system, Aviation Weather Environment (AWE), utilizes information visualization techniques, a direct manipulation graphical interface, and a speech-based interface to improve a pilot's situational awareness of relevant weather data. The system design is based on a user study and feedback from pilots.

The engineering options for mitigating the climate impacts of aviation.  

PubMed

Aviation is a growing contributor to climate change, with unique impacts due to the altitude of emissions. If existing traffic growth rates continue, radical engineering solutions will be required to prevent aviation becoming one of the dominant contributors to climate change. This paper reviews the engineering options for mitigating the climate impacts of aviation using aircraft and airspace technologies. These options include not only improvements in fuel efficiency, which would reduce carbon dioxide (CO2) emissions, but also measures to reduce non-CO2 impacts including the formation of persistent contrails. Integrated solutions to optimize environmental performance will require changes to airframes, engines, avionics, air traffic control systems and airspace design. While market-based measures, such as offset schemes and emissions trading, receive growing attention, this paper sets out the crucial role of engineering in the challenge to develop a 'green air traffic system'.

Survey of equatorial magnetospheric-wave activity between 5 and 8 R(E). Technical report  

SciTech Connect

We report the results of a survey of ELV/VLF wave activity in the frequency range from 100 Hz to 5 kHz observed by the SCATHA satellite near the magnetic equator between 5 and 8 R sub E. The typical wave environment in this region is required to assess the role of each type of wave in transport processes, such as the pitch-angle diffusion of electrons, occurring in the outer magnetosphere. Hiss, discrete whistler-mode emissions, and electron cyclotron harmonic waves occur within the frequency range of the SCATHA VLF receiver. Hiss is predominantly observed between noon and dusk where the satellite frequently enters the plasmasphere. Discrete whistler-mode emissions occur over 60% of the time between 0300 and 1200 LT. A surprising result of the survey is the absence of activity in the local time sector from 18 to 21 h. No wave activity above the receiver noise level, 5 x 10 to the minus 7th power V/m-Hz1/2, was detected during 50% of the broadband data acquisitions in this region.

A Survey on Activities of Daily Living and Occupations of Upper Extremity Amputees  

PubMed Central

Objective To assess prosthetic use by upper extremity amputees, and their difficulties with prostheses in activities of daily living and occupations. Method This study is based on a survey of 307 subjects, who were using prostheses manufactured in the Center of Prosthetics and Orthotics. The survey questionnaire included items about general demographic characteristics, side and level of amputation, type of prosthesis and its use, and difficulties in the activities of daily living, employment and driving. Results The most common type of prosthesis was the cosmetic hand type (80.2%). There were no statistically significant correlations between satisfaction with prosthesis and the amputation level or type of prosthesis. The most common difficulties in daily living activities experienced by amputees were lacing shoes, removing bottle-tops with a bottle opener, and using scissors. Only 7.3% of amputees received rehabilitation services. Less than half of the amputees (44.7%) used their prostheses for eight or more hours a day, and 76.9% used their prostheses for regular or irregular cosmetic purposes. After amputation, most of the respondents (69.0%) became unemployed or changed workplaces. Conclusion In our study, respondents preferred cosmetic usage to functional usage. Only 30.0% of respondents reported satisfaction with their prostheses. Many of the amputees had difficulties in complex tasks and either changed jobs or became unemployed. Clerical workers were the occupation group, which was most likely to return to work. The development of a more functional prosthetic hand and additional rehabilitation services are required.

The development of an arm activity survey for breast cancer survivors using the Protection Motivation Theory  

PubMed Central

Background Current research evidence indicates that women should return to normal use of their arm after breast cancer surgery. However, it appears some women continue to hold the view that they are supposed to protect their arm from strenuous activities because of the risk of lymphoedema. Many factors contribute to women's perceptions about lymphoedema and their ability to use their affected arm, and it is the aim of this study to explore and understand these perceptions. Methods/design A survey, based on the Protection Motivation Theory, has been developed and tested. The survey assesses whether subjective norms, fear and/or coping attributes predict women's intention to use their affected arm. In addition, the survey includes questions regarding cancer treatment and demographic characteristics, arm and chest symptoms, and arm function. Recruitment of 170 breast cancer survivors has begun at 3 cancer treatment sites in Sydney, Australia. Discussion This study will identify perceptions that help predict the extent women use their affected arm. The results will also determine whether upper limb impairments arise secondary to over-protection of the affected arm. Identification of factors that limit arm use will enable appropriate prevention and better provision of treatment to improve upper limb outcomes.

THE COSMOS ACTIVE GALACTIC NUCLEUS SPECTROSCOPIC SURVEY. I. XMM-NEWTON COUNTERPARTS  

SciTech Connect

We present optical spectroscopy for an X-ray and optical flux-limited sample of 677 XMM-Newton selected targets covering the 2 deg{sup 2} Cosmic Evolution Survey field, with a yield of 485 high-confidence redshifts. The majority of the spectra were obtained over three seasons (2005-2007) with the Inamori Magellan Areal Camera and Spectrograph instrument on the Magellan (Baade) telescope. We also include in the sample previously published Sloan Digital Sky Survey spectra and supplemental observations with MMT/Hectospec. We detail the observations and classification analyses. The survey is 90% complete to flux limits of f {sub 0.5-10keV} > 8 x 10{sup -16} erg cm{sup -2} s{sup -1} and i {sup +} {sub AB} < 22, where over 90% of targets have high-confidence redshifts. Making simple corrections for incompleteness due to redshift and spectral type allows for a description of the complete population to i {sup +} {sub AB} < 23. The corrected sample includes a 57% broad emission line (Type 1, unobscured) active galactic nucleus (AGN) at 0.13 < z < 4.26, 25% narrow emission line (Type 2, obscured) AGN at 0.07 < z < 1.29, and 18% absorption line (host-dominated, obscured) AGN at 0 < z < 1.22 (excluding the stars that made up 4% of the X-ray targets). We show that the survey's limits in X-ray and optical fluxes include nearly all X-ray AGNs (defined by L {sub 0.5-10keV} > 3 x 10{sup 42} erg s{sup -1}) to z < 1, of both optically obscured and unobscured types. We find statistically significant evidence that the obscured-to-unobscured AGN ratio at z < 1 increases with redshift and decreases with luminosity.

The reported incidence of man-machine interface issues in Army aviators using the Aviator's Night Vision System (ANVIS) in a combat theatre  

NASA Astrophysics Data System (ADS)

Background: Army Aviators rely on the ANVIS for night operations. Human factors literature notes that the ANVIS man-machine interface results in reports of visual and spinal complaints. This is the first study that has looked at these issues in the much harsher combat environment. Last year, the authors reported on the statistically significant (p<0.01) increased complaints of visual discomfort, degraded visual cues, and incidence of static and dynamic visual illusions in the combat environment [Proc. SPIE, Vol. 7688, 76880G (2010)]. In this paper we present the findings regarding increased spinal complaints and other man-machine interface issues found in the combat environment. Methods: A survey was administered to Aircrew deployed in support of Operation Enduring Freedom (OEF). Results: 82 Aircrew (representing an aggregate of >89,000 flight hours of which >22,000 were with ANVIS) participated. Analysis demonstrated high complaints of almost all levels of back and neck pain. Additionally, the use of body armor and other Aviation Life Support Equipment (ALSE) caused significant ergonomic complaints when used with ANVIS. Conclusions: ANVIS use in a combat environment resulted in higher and different types of reports of spinal symptoms and other man-machine interface issues over what was previously reported. Data from this study may be more operationally relevant than that of the peacetime literature as it is derived from actual combat and not from training flights, and it may have important implications about making combat predictions based on performance in training scenarios. Notably, Aircrew remarked that they could not execute the mission without ANVIS and ALSE and accepted the degraded ergonomic environment.

Analysis of emission data from global commercial aviation: 2004 and 2006  

NASA Astrophysics Data System (ADS)

The global commercial aircraft fleet in 2006 flew 31.26 million flights, burned 188.20 million metric tons of fuel, and covered 38.68 billion kilometers. This activity emitted substantial amounts of fossil-fuel combustion products within the upper troposphere and lower stratosphere that affect atmospheric composition and climate. The emissions products, such as carbon monoxide, carbon dioxide, oxides of nitrogen, sulfur compounds, and particulate matter, are not emitted uniformly over the Earth, so understanding the temporal and spatial distributions is important for modeling aviation's climate impacts. Global commercial aircraft emission data for 2004 and 2006, provided by the Volpe National Transportation Systems Center, were computed using the Federal Aviation Administration's Aviation Environmental Design Tool (AEDT). Continuous improvement in methodologies, including changes in AEDT's horizontal track methodologies, and an increase in availability of data make some differences between the 2004 and 2006 inventories incomparable. Furthermore, the 2004 inventory contained a significant over-count due to an imperfect data merge and daylight savings error. As a result, the 2006 emissions inventory is considered more representative of actual flight activity. Here, we analyze both 2004 and 2006 emissions, focusing on the latter, and provide corrected totals for 2004. Analysis of 2006 flight data shows that 92.5% of fuel was burned in the Northern Hemisphere, 69.0% between 30N and 60N latitudes, and 74.6% was burned above 7 km. This activity led to 162.25 Tg of carbon from CO2 emitted globally in 2006, more than half over three regions: the United States (25.5%), Europe (14.6), and East Asia (11.1). Despite receiving less than one percent of global emissions, the Arctic receives a uniformly dispersed concentration of emissions with 95.2% released at altitude where they have longer residence time than surface emissions. Finally, 85.2% of all flights by number in 2006 were short-haul missions, yet those flights were responsible for only 39.7% of total carbon from CO2. The following is a summary of these data which illustrates the global and regional aviation emissions footprints for 2004 and 2006, and provides temporal and spatial distribution statistics.

Relationship Between Accelerometer-based Measures of Physical Activity and the Yale Physical Activity Survey in Adults with Arthritis  

PubMed Central

Objective To evaluate the correlation between the Yale Physical Activity Survey (YPAS) scores and objective accelerometer measures of time spent in light, moderate-to-vigorous intensity physical activities (MVPA), and moderate-to-vigorous activities in bouts lasting at least 10 minutes. Methods This study analyzed baseline data from 171 persons with RA and 139 persons with OA in a randomized clinical trial (IMPAACT). Persons fulfilling the 1988 ACR criteria for RA and persons with symptomatic, radiologic knee OA (Kellgren-Lawrence Class ? 2) wore an accelerometer for 7 days, then responded to the YPAS questionnaire, and questions regarding demographics (age, gender, and race) and health factors [BMI, disease status (HAQ/WOMAC), comorbidities, pain and function]. Spearman Correlation coefficients were estimated between each YPAS summary measure and accelerometer measures. Results In the RA participants the strongest correlation was between the YPAS Activity Dimensions Summary Index (Y-ADSI) and Average Daily Minutes of Bouted Moderate/Vigorous Activity (r = 0.51). Additionally, the Y-ADSI correlated significantly with both objectively measured average daily accelerometer counts (r= 0.45) and average daily minutes of Moderate/Vigorous Activity (r = 0.43). For OA participants, a similar pattern emerged: the Y-ADSI had significant correlations with average daily minutes of Bouted Moderate/Vigorous Activity (r = 0.36), average daily minutes of Moderate/Vigorous Activity (r = 0.31), and average daily counts (r = 0.24). Conclusions For both RA and OA groups, the summary index Y-ADSI had the strongest significant correlations with objectively measured physical activity, which supports Y-ADSI use as a tool for clinical applications and in rheumatology research.

Pandemic Diseases and the Aviation Network SARS, a case study  

NASA Astrophysics Data System (ADS)

We investigate the mechanisms of the worldwide spread of infectious diseases in a modern world in which humans travel on all scales. We introduce a probabilistic model which accounts for the worldwide spread of infectious diseases on the global aviation network. The analysis indicates that a forecast of the geographical spread of an epidemic is indeed possible, provided that local dynamical parameters of the disease such as the basic reproduction number are known. The model consists of local stochastic infection dynamics and stochastic transport of individuals on the worldwide aviation network which takes into account over 95% of the entire the national and international civil aviation traffic. Our simulations of the SARS outbreak are in surprisingly good agreement with published case reports. Despite the fact that the system is stochastic with a high number of degrees of freedom the outcome of a single simulation exhibits only a small magnitude of variability. We show that this is due to the strong heterogeneity of the network ranging from a few two over 25,000 passengers between nodes of the network. Thus, we propose that our model can be employed to predict the worldwide spread of future pandemic diseases and to identify endangered regions in advance. Based on the connectivity of the aviation network we evaluate the performance of different control strategies and show that a quick and focused reaction is essential to inhibit the global spread of infectious diseases.

Racing bodies: dress and pioneer women aviators and racing drivers  

Microsoft Academic Search

This article explores the dress of pioneer women racing drivers and aviators in the period 1900–39. It traces how they transformed their dress and appearance from the amateur improvisations of the Edwardian period to the streamlined ‘speed queens’ of the 1930s. It argues that their various clothing strategies represented and embodied their determined negotiation of boundaries and frontiers of culture

Fatal aviation accidents in Lower Saxony from 1979 to 1996.  

PubMed

So far no national or regional studies have been published in Germany regarding the number of fatal aviation accidents and results of autopsy findings. Therefore, we evaluated all fatal aviation accidents occurring in Lower Saxony from 1979 to 1996. A total of 96 aviation accidents occurred in this period involving 73 aeroplanes. The crashes resulted in the death of 154 people ranging in age from 19 to 68 years. The greatest number of victims in a single crash of an aircraft was (n=7). Other types of fatal accidents were crashes of aircraft and helicopter while on the ground (n=5), hot-air balloons (n=2), parachutes (n=10), hang glider accidents (n=5) and the striking of a bystander by a model airplane. Autopsies were performed on 68 of the 154 victims (44.2%), including 39 of the 73 pilots (53.4%). Some of the autopsies yielded findings relevant to the cause of the accident: gunshot wounds, the presence of alcohol or drugs in blood and preexisting diseases. Our findings emphasize the need for autopsy on all aviation accident victims, especially pilots, as this is the only reliable method to uncover all factors contributing to an accident. PMID:11348795

Driving automation: learning from aviation about design philosophies  

Microsoft Academic Search

Whether we like it or not, automation is gradually taking over the driver's role. Full vehicle automation is predicted to be on British roads by 2030 (Walker et al., 2001). However, experience in aviation gives us some cause for concern for the 'drive-by-wire' car (Stanton & Marsden, 1996). Problems of workload and situation awareness have been attributed as the root
