Smooth regulation of calorifier output


, : Smooth regulation of calorifier output. Mekhanizatsiya i Elektrifikatsiya Sel' skogo Khozyaistva ( 1): 14-15

A system of pipe and calorifier heaters designed for heating a 1500 msuperscript 2 greenhouse (hangar-type) with +or-1 degrees C accuracy is described. A specially designed instrument automatically regulates the speed of calorifier fans, taking into consideration the amount of solar radiation available.

The vacuolar ATPase enzyme complex (V-ATPase) pumps protons across membranes, energized by hydrolysis of ATP. Extensive investigations on structural and biochemical features of these molecules have implied their importance in the physiological pro...

Improving saccharification efficiency in bioenergy crop species remains an important challenge. Here, we report the characterization of a Sorghum (Sorghum bicolor L.) mutant, named REDforGREEN (RG), as a bioenergy feedstock. It was found that RG d...
