Total Energy Expenditure, Energy Intake ... SpringerLink

Total energy expenditure (TEE) is composed of the energy costs of the processes essential for life (basal metabolic rate (BMR), 60–80% of TEE), of the energy expended in order to digest, absorb, and convert food (dietinduced thermogenesis, ~10%), and the energy expended during physical activities (activity energy expenditure, ~15–30%) [1 ...

The effects of acylation stimulating ... BMC Physiology

Acylation stimulating protein (ASP) is an adipogenic hormone that stimulates triglyceride (TG) synthesis and glucose transport in adipocytes. Previous studies have shown that ASPdeficient C3 knockout mice are hyperphagic yet lean, as they display increased oxygen consumption and fatty acid oxidation compared to wildtype mice. In the present study, antibodies against ASP (AntiASP) and human ...

Aluminium Extraction And Recycling Plant

· Aluminium life cycle. There are around 29 billion tonnes of known reserves of bauxite and at the current rate of extraction, these reserves will last us more than 100 years. There are, however, vast undiscovered resources that may extend the time perspective to 250340 years. Recycling. Recycling aluminium takes only 5% of the energy.

Aluminium is formed at about 900°C, but once formed has a melting point of only 660°C. In some smelters this spare heat is used to melt recycled metal, which is then blended with the new metal. Recycled metal requires only 5 percent of the energy required to make new metal.

This means that when it is compared to indirect calorimetry, the reverse Fick method typically underestimates the total body energy expenditure, though not by a lot (on average it seems to be about 88kcal/day). Obviously, when the energy expenditure of the lung is massively increased (eg. in ARDS) this method will be much more inaccurate.
