Indirect calorimetry in the assessment of the energy requirement in overweight and obese women

Lange E., Głąbska D., Włodarek D

Advances in Science and Technology. Research Journal

2013

Vol. 7, nr 20

91--97

Individual total energy expenditure may be calculated as a sum of basal energy requirement and energy expenditure associated with physical activity. Measurement of basal energy requirement is not often conducted in dietetic practice, but may be applied using indirect calorimetry. The aim of the analysis was to present the possibilities of using the Fitmate PRO monitor in the assessment of resting metabolic rate and basal energy expenditure with a method of indirect calorimetry in a group of 91 overweight and obese women in various age. The mean results of the resting metabolic rate measured with method of indirect calorimetry using the Fitmate PRO monitor did not differ in the age groups of overweight and obese women. The results of the resting metabolic rate measured with method of indirect calorimetry using the Fitmate PRO monitor were correlated with body mass, height, fat mass, muscle mass and waist circumference. The Fitmate PRO monitor may be a valuable tool in everyday dietetic practice to assess the basal energy expenditure with method of indirect calorimetry in a group of overweight and obese women.

Investigation of the skull melting method for the generation of particulate material of inorganic compounds

Riemer B., Lange E., Hameyer K.

Archives of Electrical Engineering

2011

Vol. 60, nr 2

197-209

This paper describes the application of the skull melting method for an artificial generation of particulate material of inorganic compounds like CsOH, NaOH, SnO2 and UO2. The skull melting process is analyzed analytically. Thereby the electromagnetic field is calculated by a one dimensional time harmonic model. Thermal losses are estimated by simple analytical formulas. Finally an electromagnetic thermal field coupling is performed to calculate the temperature distribution inside the crucible, considering transient thermal effects. The skull melting process is simulated for the example of UO2. Under consideration of the given material properties it is shown that the skull melting method can be applied to fuse UO2.
