Dentistry's Social Contract and the Loss of Professionalism.

The social contract between society and the dental profession is essential to the ability to provide high quality dental care to patients. The social contract defines the profession and its place in society, giving the profession its legitimacy. Society bestows benefits upon the dental profession in exchange for our ability to alleviate pain and suffering caused by oral disease. This article seeks to explore the nature of this social contract in the provision of oral healthcare and what may become of the pr...

Airport take-off noise assessment aimed at identify responsible aircraft classes.

Assessment of aircraft noise is an important task of nowadays airports in order to fight environmental noise pollution given the recent discoveries on the exposure negative effects on human health. Noise monitoring and estimation around airports mostly use aircraft noise signals only for computing statistical indicators and depends on additional data sources so as to determine required inputs such as the aircraft class responsible for noise pollution. In this sense, the noise monitoring and estimation syste...

International tourist arrival figures reached 1087 million in 2013 and 1133 million in 2014; of which 53% and 54% respectively accounted for air transport. The water on board aircraft is sourced from surface or ground water; piped to a central filling point and distributed to each aircraft by water service vehicles at the home base or at the destination airport. The purpose of this study was to ascertain the microbial, chemical (pH; Total and Fr...

Accident-precipitating factors for crashes in turbine-powered general aviation aircraft.

General aviation (14CFR Part 91) accounts for 83% of civil aviation fatalities. While much research has focused on accident causes/pilot demographics in this aviation sector, studies to identify factors leading up to the crash (accident-precipitating factors) are few. Such information could inform on pre-emptive remedial action. With this in mind and considering the paucity of research on turbine-powered aircraft accidents the study objectives were to identify accident-precipitating factors and determine if...

This study compared four treatment protocols to reduce airborne composite fiber particulates during simulated aircraft crash recovery operations.

Missing Aircraft Crash Sites and Spatial Relationships to the Last Radar Fix.

Few studies have examined the spatial characteristics of missing aircraft in actual distress. No previous studies have looked at the distance from the last radar plot to the crash site. The purpose of this study was to characterize this distance and then identify environmental and flight characteristics that might be used to predict the spatial relationship and, therefore, aid search and rescue planners.

Wearable Accelerometers in High Performance Jet Aircraft.

Wearable accelerometers have become ubiquitous in the fields of exercise physiology and ambulatory hospital settings. However, these devices have yet to be validated in extreme operational environments. The objective of this study was to correlate the gravitational forces (G forces) detected by wearable accelerometers with the G forces detected by high performance aircraft.

Cooperation driven coherence: Brains working hard together.

The current study aims to look at the difference in coupling of EEG activity of participant pairs while they perform a cooperative, concurrent, independent yet different task at high and low difficulty levels. Participants performed the National Aeronautics and Space Administration (NASA) designed Multi-Attribute Task Battery (MATB-II) task which simulates a pilot and copilot operating an aircraft. Each participant in the pair was responsible for 2 out of 4 subtasks which were independent and different from...

Airborne measurements of organosulfates over the continental U.S.

Organosulfates are important secondary organic aerosol (SOA) components and good tracers for aerosol heterogeneous reactions. However, the knowledge of their spatial distribution, formation conditions, and environmental impact is limited. In this study, we report two organosulfates, an isoprene-derived isoprene epoxydiols (IEPOX) (2,3-epoxy-2-methyl-1,4-butanediol) sulfate and a glycolic acid (GA) sulfate, measured using the NOAA Particle Analysis Laser Mass Spectrometer (PALMS) on board the NASA DC8 aircra...

Bay breeze influence on surface ozone at Edgewood, MD during July 2011.

Surface ozone (O3) was analyzed to investigate the role of the bay breeze on air quality at two locations in Edgewood, Maryland (lat: 39.4°, lon: -76.3°) for the month of July 2011. Measurements were taken as part of the first year of NASA's "Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality" (DISCOVER-AQ) Earth Venture campaign and as part of NASA's Geostationary for Coastal and Air Pollution Events Chesapeake Bay Oceanographic campaign wi...

The U.S. Public׳s Investment in Medical Research: An Evolving Social Contract.

Medical researchers and their institutions are operating under extraordinary financial stress. More than a decade after completion of the 5-year doubling of the National Institutes of Health budget, the medical research community must confront a significant loss in National Institutes of Health purchasing power and downward pressures in federal discretionary spending. In part, this trend results from a federal budget stalemate over the growth in entitlement programs, particularly spending on medical care. T...

Evaluating Bone Loss in ISS Astronauts.

The measurement of bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) is the Medical Assessment Test used at the NASA Johnson Space Center to evaluate whether prolonged exposure to spaceflight increases the risk for premature osteoporosis in International Space Station (ISS) astronauts. The DXA scans of crewmembers' BMD during the first decade of the ISS existence showed precipitous declines in BMD for the hip and spine after the typical 6-mo missions. However, a concern exists that skelet...

Preserving the Social Contract of Health Care-A Call to Action.

News of police brutality toward minorities in urban centers has become so commonplace that it seems to echo indifference over anger. Yet, protesters and other activists across the country, including ones in Baltimore, Maryland, this past May, embody a visceral discontent with the breach of the social contract between law enforcement and the communities they serve. These episodes of violence only fuel the fire of mistrust among underserved, minority groups and are painful reminders of generations of poor soc...
