Resting energy expenditure (REE)-power relationships result from multiple underlying factors including weight and height. In addition, detailed body composition, including fat free mass (FFM) and its components, skeletal muscle mass and internal organs with high metabolic rates (i.e. brain, heart, liver, kidneys), are major determinants of REE. Since the mass of individual organs scales to heig...

Current recommendations for energy requirements in the elderly are based on assumed levels of physical activity relative to BMR (1.5 x BMR). The main aim of the present study was to establish whether these recommendations might be applicable to a randomly-selected group of free-living elderly men (all over 75 years of age). BMR was measured by indirect calorimetry and total energy expenditure (...

The objective of the present study was to investigate the contribution of intra-individual variance of resting energy expenditure (REE) to interindividual variance in REE. REE was measured longitudinally in a sample of twenty-three healthy men using indirect calorimetry. Over a period of 2 months, two consecutive measurements were done in the whole group. In subgroups of seventeen and eleven su...

This experiment investigated the effects of increasing the dietary content of bacterial protein meal (BPM) on the protein and energy metabolism of pigs from weaning to a live weight of 80 kg. Four litters with four castrated male pigs in each litter were used. The litters were divided into two blocks according to age. One pig from each litter was fed one of the four experimental diets. Soya-bea...

Glucose dynamics, energy metabolism, and nitrogen balance were studied in eight malnourished cancer patients and seven malnourished patients without cancer. Glucose flux was measured by single injection of [6-3H]glucose and [U-14C]glucose. Energy expenditure was measured by indirect calorimetry. Each patient was studied after an overnight fast and during constant gastric infusion of a formula d...

Selenium and dental depigmentation 41 incidence of liver necrosis, it had no apparent effect on the depigmentation of the rats’ incisors which takes place if these animals are fed on a diet deficient in tocopherol, and which is prevented only by this vitamin. 4. The parallelism between the effect of selenium and of vitamin E, both of which prevent liver necrosis and prolong the survival time of...

Purpose. To critically review the validity of accelerometry-based prediction models to estimate activity energy expenditure (AEE) in children and adolescents. Methods. The CINAHL, EMBASE, PsycINFO, and PubMed/MEDLINE databases were searched. Inclusion criteria were development or validation of an accelerometer-based prediction model for the estimation of AEE in healthy children or adolescents (...

The corresponding author’s family name and given name were not included correctly and were inverted with given name being ‘Martin Sundström’ and family name being ‘Rehal’. The names are included correctly here, where ‘Martin’ is the given name and ‘Sundström Rehal’ is the family name. This will be corrected in the origi...

Distillation column is one of the most common operations in process industries and is while the most expensive unit of the amount of energy consumption. Many ideas have been presented in the related literature for optimizing energy consumption in distillation columns. This paper studies the different heat integration methods in a distillation column which separate Benzene, Toluene, Xylene, and ...
