Weakly populated multinucleon transfer channels studied with a new time-of-flight magnetic spectrometer

Journal of Physics G: Nuclear and Particle Physics, 1997
A new time-of-flight spectrometer with magnetic quadrupoles has been developed. Its high detection efficiency and resolution allows one to identify ions produced with low cross sections in a binary reaction. The study of multinucleon transfer channels in the system revealed a large drift of the experimental total cross sections with respect to ...

Feeding rates, nutritional status and flight dispersal potential of peridomestic populations of Triatomainfestans in rural northwestern Argentina

Acta Tropica, 2005
Triatoma infestans, the main vector of Chagas disease in Southern Cone countries, frequently infests peridomestic structures housing domestic animals. A total of 814 T. infestans collected from 35 different peridomestic sites in rural northwestern Argentina over 1-4 consecutive seasons was examined for recent blood meals and nutritional status.

Optimization of the LAX – JFK Flight Route to Minimize Population Exposure to Sonic Booms

2020
Supersonic aircraft, or aircraft that travel faster than the speed of sound, are restricted from flying over the United States because of the loud (and potentially destructive) sonic booms they produce. Concorde is arguably the most famous commercial supersonic aircraft, and before being retired in 2003, it was able to fly between New York and London ...

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]).

In-Flights of Outbreak Populations of Mountain Pine Beetle Alter the Local Genetic Structure of Established Populations a Decade After Range Expansion

AbstractMountain pine beetles began to appear at epidemic levels in Alberta, Canada, in 2006, following six years of extensive outbreaks in neighboring British Columbia. We assessed the effect of genetic MPB in-flights from the peak of the outbreak on the genetic structure of established populations of MPB and the change over time in novel regions ...

Effects of ozone on symptoms and cardiopulmonary function in a flight attendant surrogate population.

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.
