As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermal, chemical, and biochemical methods.rops, such as corn and sugar cane, can be fermented to produce the transportation fuel, ethanol. Biodiesel, another transportation fuel, can be produced from left-over food products like vegetable oils and animal fats. Also, biomass to liquids (BTLs) and cellulosic ethanol are still under research.
Protein-energy wasting (PEW), a term proposed by the International Society of Renal Nutrition and Metabolism (ISRNM), refers to the multiple nutritional and catabolic alterations that occur in chronic kidney disease (CKD) and associate with morbidity and mortality.
Energy expenditure concerns calories burned versus calories consumed. Imbalances between the two determine weight loss, gain or maintenance. Bodies that store too much energy become overweight. One component of your expenditure is basal metabolic rate -- the energy you burn when inactive.The other two components are activity thermogenesis, which are the calories burned during activity, and the thermic effect of foods, which concerns calories used to digest foods you eat.mbalances between the two determine weight loss, gain or maintenance.
