The flowers or inflorescences of certain primitive seed plants are able to regulate their temperature during blooming by modulating the rate of heat production to remain much warmer than the surroundings. A large drop in ambient temperature causes a smaller drop in flower temperature which causes an increase in the rate of heat production by futile involvement of the cytochrome and alternative ...

The heat production has been measured of Merino lambs, with the coat artificially dried, less than 7 hr old, in still air at 68”F, and of the same lambs in a wind at the same temperature, with the coat artificially wetted. Indirect calorimetry was used. When the coat was wet the heat production ranged from 18-137 per cent. higher than when it was dry. The water which evaporated from the coat ab...

Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 48: 4.1 4.6. A metabolic calorimeter system was developed to facilitate collection of metabolic data from 24 embryos within an incuba...

Electrolyte temperature is a key factor in excess heat production using Pd|D2O+H2SO4 electrolytic cells. Best results are obtained when the electrolyte temperature is close to the boiling point. Stable excess heat is generated by events on or near the Pd cathode surface. In addition to the stable excess heat, heat bursts are sometimes observed. These occurred most frequently in experiments usin...

This paper presents a thermodynamic analysis of a biochemical process for the production of bioethanol from a lignocellulosic feedstock. The major inefficiencies in the process are identified as: i) the combustion of lignin for process heat and power production and ii) the simultaneous saccharification and fermentation process. As lignin is not converted to ethanol and lignin has a high value o...
