1. A calorimeter for the continuous measurement of heat production and heat loss in the human subject, for at least 24 h, is described. The calorimeter operated on the heat-sink principle for direct calorimetry and an open-circuit system for indirect calorimetry. 2. Sensible heat loss was measured using a water-cooled heat exchanger, and the temperature of water entering the heat exchanger was ...

this study was conducted to determine the effect of dietary turmeric rhizome powder (trp) as a natural antioxidant, and soybean oil, canola oil and tallow on lipid metabolism, blood metabolites, immune system, and antioxidant status of broiler chickens before (bhs, 28 d) and after exposure to heat stress (ahs, 42 d). seven hundred and ninety two d-old male arian broilers were randomly allotted ...

recent developments in hydrogen production by thermochemical water decomposition are reported,with an emphasis on hydrogen production from non-fossil energy sources such as nuclear and solar. numerousdevelopments have been made on sulphur-iodine, copper-chlorine and other thermochemicalcycles. efforts are described to lower the temperatures required in thermochemical cycles, so as to broadenthe...

We apply several physical ideas to determine the steady temperature distribution in a medium moving with uniform velocity between two infinite parallel plates. We compute it in the coordinate frame moving with the medium by integration over the “past” to account for the influence of an infinite set of instantaneous point sources of heat in past moments as seen by an observer moving with the med...

There is a gap between the population growth and protein supply in many tropical countries where per capita income is low and the majority of people consume less protein than a daily standard for recommended protein intake. Poultry egg production remains the fastest route to bridging the protein demand-supply gap in these regions. However, poultry are faced with heat stress in the tropics which...
