In this Letter, an N-body theory for the radiative heat exchange in thermally nonequilibrated discrete systems of finite size objects is presented. We report strong exaltation effects of heat flux which can be explained only by taking into account the presence of many-body interactions. Our theory extends the standard Polder and van Hove stochastic formalism used to evaluate heat exchanges betw...

Potential sources of gaseous microemboli during cardiopulmonary bypass are varied. However, it is known that membrane oxygenators generate fewer gaseous microemboli than bubble oxygenators and that bubblers cannot utilize arterial heat exchange without generating significant gaseous microemboli during rewarming. A membrane oxygenator utilizing simultaneous gas and heat exchange raises the con...

We have observed a 'heat-sensitisation' phenomenon in a large proportion of patients receiving suspended moxibustion treatment. Patients become thermally sensitised to moxibustion stimulation at certain locations on the body, indicated by sensations of strong warmth or heat penetrating into the body (heat penetration), warmth spreading around the stimulation site (heat expansion), warmth conduc...

The increase in dissipated power per unit area of electronic components sets higher demands on the performance of the heat sink. Also if we continue at our current rate of miniaturisation, laptops and other electronic devices can get heated up tremendously. Hence we require a better heat dissipating system to overcome the excess heat generating problem of using nanoelectronics, which is expecte...

Temperature profoundly influences physiological responses in animals, primarily due to the effects on biochemical reaction rates. Since physiological responses are often exemplified by their rate dependency (e.g., rate of blood flow, rate of metabolism, rate of heat production, and rate of ion pumping), the study of temperature adaptations has a long history in comparative and evolutionary phys...

the present study was carried out to investigate the replacement of soybean meal by different levels of canola meal (either with or without canola meal undergoing heat processing). two hundred forty commercial layer hens (lsl strain) at 54th week of age, selected based on the same egg production percentage and body weight. the experimental design was a crd, in a factorial arrangement of 4 repli...

Heat waves have been responsible for more deaths worldwide than all other natural disasters combined. In Europe, this “silent killer” caused 70000C excess deaths in 2003, and more recently 3500C people died during 2 separate heat waves in India (May 2015) and Pakistan (June 2015) (Fig. 1). Groups among the most vulnerable include the elderly, poor, and people with cardiovascular disease. Identi...

Heat stress can have large effects on most aspects of reproductive function in mammals. These include disruptions in spermatogenesis and oocyte development, oocyte maturation, early embryonic development, foetal and placental growth and lactation. These deleterious effects of heat stress are the result of either the hyperthermia associated with heat stress or the physiological adjustments made ...

Two nomograms are presented. The first enables the mean surface and body temperatures and the body heat content of a patient of given weight to be determined from measurements of skin temperature at three sites and of the core (rectal) temperature. The second enables the change in heat content of such a patient to be determined from the change in mean body temperature.
