Heat and Human Body

The Radiation of Heat from the Human Body

In the past few years the interest in an accurate knowledge of the temperature of the surface of the skin and of the energy radiated therefrom has greatly increased. This interest has been due on the one hand to the important part played by radiation in the theories of ventilation and on the other to the desire to make a more accurate analysis of the factors involved in human metabolism. Human ...

Radiative heat transfer: many-body effects

Heat transfer by electromagnetic radiation is one of the common methods of energy transfer between objects. Using the fluctuation-dissipation theorem, we have studied the effect of particle arrangement in the transmission of radiative heat in many-body systems. In order to show the effect of the structure morphology on the collective properties, the radiative heat transfer is studied and the re...

Can intradermal administration of angiotensin II influence human heat loss responses during whole body heat stress?

It is unclear if angiotensin II, which can increase the production of reactive oxygen species (oxidative stress), modulates heat loss responses of cutaneous blood flow and sweating. We tested the hypothesis that angiotensin II-induced increases in oxidative stress impair cutaneous perfusion and sweating during rest and exercise in the heat. Eleven young (24 ± 4 yr) healthy adults performed two ...

Quantum mechanical proton range in human body

Introduction: Proton therapy delivers radiation to tumor tissue in a much more confined way than conventional photon therapy thus allowing the radiation oncologist to use a greater dose while still minimizing side.   Materials and Methods: protons release most of their energy within the tumor region. As a result, the treating physician can potentially give an...
