Insecticides are the most common strategy used for the management of mosquitoes. Changes in ambient temperature can alter the toxicity of insecticides to ectothermic organisms. Studies show organophosphate insecticides exhibit a positive correlation between ambient temperature and mortality for many insect species, and carbamate insecticides exhibit a slightly negative correlation between ambie...

The rostral brainstem of the harbor seal Phoca vitulina was cooled and heated 33-41 degrees C while oxygen consumption and rectal, hypothalamic, flipper and dorsal skin temperatures were measured. These experiments were made on restrained seals at ambient temperatures -15 to 30 degrees C. Cooling the preoptic and hypothalamic (POH) tissue increased oxygen consumption in a way that could be appr...

Entropy generation in an unsteady hydromagnetic Couette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates in a rotating system have been analyzed. Both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient following the Newton's law of cooling. A numerical solution for governin...

gamma aminobutyric acid (gaba) is one of the inhibitory neurotransmitters that may have the ability torelieve the intensity of stress. heat stress remains a major threat for duck production in summer in most areas of china. the current study was conducted to investigate the effect of dietary gaba on performanceparameters and plasma metabolites of heat exposed ducks. two thousand cherry valley d...

Studies show that ambient temperature and air pollution are associated with cardiovascular disease and that they may interact to affect cardiovascular events. However, few epidemiologic studies have examined mechanisms through which ambient temperature may influence cardiovascular function. The authors examined whether temperature was associated with heart rate variability (HRV) in a Boston, Ma...

A non-contact method for the measurement of emissivity, and emissivity-corrected temperatures has been developed, where the ambient radiation-temperature is changed in a discontinuous way. When the ambient radiation-temperature is changed quickly, so that the surface temperature of the object can be assumed to be unchanged, the radiometer output before, and immediately after that change can be ...
