A ballistic bomb calorimeter.
The classical methods for determining the calorie value of foodstuffs are both long and tedious, and a number of alternative methods have been suggested for assessing the energy value of foods based on an analysis of the foodstuff and the use of factors with each of the chemical components to give energy content. None of these methods is really satisfactory, and when a high level of accuracy is...
متن کاملA Polystyrene-Water Calorimeter
The paper describes a new type of calorimeter that can be quickly put into operation for determining absorbed dose at a point in polystyrene. It also describes a unique method of decreasing drifts in electrical signals caused by temperature gradients. Two calibrated thermistors were placed close together between sandwiched polystyrene discs that were immersed in water. The assembly was irradiat...
متن کاملDescription of a Dual Calorimeter
A dual calorimeter is described which can be used to study electrolytic processes. Experience with this instrument has revealed several deficiencies inherent in the isoperibolic calorimeter design that apply to all calorimeters of this type when used to study the cold fusion effect. I. BACKGROUND A calorimeter has been designed to measure heat energy produced in a Pons-Fleischmann type electrol...
متن کاملThe Respiration Calorimeter
In considering the demands of the body for nourishment and the purposes which foods serve in the body, it was natural that experimenters should direct their attention for a time largely to those questions which were most readily studied, such as the amounts of food eaten and their relation to growth, health, and other physical conditions. The chemical composition of different foods and the purp...
متن کاملNEMO - 3 Calorimeter Electronics
The calorimeter electronics of the NEMO-3 double beta decay experiment fulfills three functions: energy measurement of the electrons by measuring the charge of the pulses, time measurement, fast first level triggering. The electronics of the 1940 Scintillator-PM modules is implemented as 40 "9U x 400mm VME" boards of up to 51 channels. For each channel the analog signals conditioning is impleme...
