Flight morphology in fragmented populations of a rare British butterfly, Hesperia comma
Biological Conservation, 1999Abstract In modern landscapes, many populations of rare species are restricted to fragments of formerly extensive habitat. However, the potential for evolutionary changes in dispersal ability to occur within these fragmented populations has received little attention.

Comparison of anthropometry of Brazilian and US Military population for flight deck design
International Journal of Industrial Ergonomics, 2018Abstract A valid anthropometric dataset is essential to optimize the design of personal equipment and aircrafts. Until recently there were no anthropometric data available for the Brazilian Air Force (FAB) pilot population, and hence international military data have often been used in Defense procurement specifications.

L'Encephale, 2017
The aim of our study was to investigate the influence of demographic factors (gender and age), work related factors (the position and years of practice) and psychosocial risk factors (cognitive demands, demands to hide emotions, work-family conflict, offensive behaviors…) on the development of burnout among flight attendants, and the nature of ...

STATUS SELECTIVE WHITE FLIGHT AND CENTRAL CITY POPULATION CHANGE: A COMPARATIVE ANALYSIS*
Journal of Regional Science, 1980The present study is concerned with evaluating the roles of previously suggested policy-alterable factors and more fundamental demographic structural features of the metropolitan area as determinants of status-specific white city- to-suburb movement. The multivariate analysis employs census migration data pertaining to the 1965-1970 period for 39 large

Angiology, 1996
Cardiovascular disease is the most common reason for loss of license among commercial flight pilots. This study was done to explore cardiovascular risk factors among aircrew officers. The study group consisted of 113 male commercial flight aircrew officers (aviators), aged thirty-five to forty-four years (mean: 38.8 years) who ...

Journal of Genetics, 2014
In the present study, we tested the hypothesis whether flight-related traits such as wing area, flight-muscle ratio, wing loading and dispersal yield evidence of geographical variation in nine wild-collected as well as laboratory-reared (at 21°C) latitudinal populations of Drosophila melanogaster from the Indian subcontinent.

Aviation, space, and environmental medicine, 1980
Two studies were conducted to ascertain the lowest ozone concentration threshold for statistically significant adverse effects on cardiopulmonary function and symptoms in male and female surrogates of the flight attendant population. Both studies simulated in-flight environmental conditions at 1,829 m mean sea level (MSL) chamber altitude.

GENES IN FLIGHT: POPULATION GENOMICS OF ADAPTIVE DIVERSITY IN HELICONIUS ERATO
Neotropical biodiversity hotspots such as the Amazon and the Atlantic Forest concentrate extraordinary species richness and endemism, but are experiencing rapid habitat loss and climate change. These processes alter not only species distributions but also the underlying genetic diversity and adaptive potential of populations, with largely unknown ...openaire +1 more source
Population density and flight dynamics of economically important pests in apricots
Изследването анализира популационната плътност и динамиката на летежа на икономически важни неприятели при кайсията – прасковен клонков молец (Anarsia lineatella Zeller, 1839) и източен плодов червей (Grapholita molesta (Busck, 1916) [syn. Cydia molesta]).Ivanov, Plamen, Hristozova, Maria

Flight-Control-Force-Exertion Limits and Comparisons with Pilot and Nonpilot Populations
2007This study was conducted to update data on the force that pilots (and nonpilots) can apply to flight controls so that current performance data could be compared with values for maximum allowable control forces found in sections of the Code of Federal Regulations (14 CFR 23.143 and 25.143).
