The effect of heating and cooling on heart rate in the estuarine crocodile Crocodylus porosus was studied in response to different heat transfer mechanisms and heat loads. Three heating treatments were investigated. C. porosus were: (1) exposed to a radiant heat source under dry conditions; (2) heated via radiant energy while half-submerged in flowing water at 23 degrees C and (3) heated via co...

How termite mounds function to facilitate climate control is still only partially understood. Recent experimental evidence in the mounds of a single species, the south Asian termite Odontotermes obesus, suggests that the daily oscillations of radiant heating associated with diurnal insolation patterns drive convective flow within them. How general this mechanism is remains unknown. To probe thi...

Thermal loading by radiant heaters is used in building heating and hot structure design applications. In this research, characteristics of the thermal radiative heating of an enclosure by a distinct heater are investigated from the second law of thermodynamics point of view. The governing equations of conservation of mass, momentum, and energy (fluid and solid) are solved by the finite volume m...

Previously we have shown in dogs that tibial bone marrow and s.c. tissue temperatures are lower than rectal temperature during the plateau phase of whole body hyperthermia with the use of a radiant heating device. In an attempt to increase thermal dose to these sites during whole body hyperthermia, we applied insulation to an extremity prior to the plateau phase of heating. We found that extrem...

AIM The aim of this study was to evaluate the effectiveness of forced-air warming for preventing perioperative hypothermia. BACKGROUND Perioperative hypothermia commonly occurs in patients receiving anaesthesia during surgeries. However, the effectiveness of warming systems requires verification. DESIGN Systematic review incorporating meta-analysis. DATA SOURCES We searched OVID, PubMed, ...
