The respiratory quotient of the excess metabolism of exercise [PDF]

Proceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1929
In recent years much controversy has been aroused as to whether the body uses carbohydrate alone in order to provide energy for the recovery process from muscular exercise, or whether the other foodstuffs can be used directly for this purpose. One of us (Furusawa), from a study of the respiratory quotient of the excess metabolism, concluded that ...

MICROBIAL METABOLIC ACTIVITY AS LEGACY OF AGRICULTURAL MANAGEMENT IN MAIZE AGROECOSYSTEMS FROM MEXICO HIGHLANDS

Tropical and Subtropical Agroecosystems, 2022
Background. Soil ecological functions such as C mineralization, enzyme activity, and microbial biomass determine the maintenance of soil fertility in the short and long term.

Vector bundles of rank four and A_3 = D_3

, 2012
Over a scheme with 2 invertible, we show that a vector bundle of rank four has a sub or quotient line bundle if and only if the canonical symmetric bilinear form on its exterior square has a lagrangian subspace.

Macronutrients as sources of food energy. [PDF]

, 2005
This background paper considers the extent to which the development of new recommendations for dietary energy requirements needs to account for the macronutrient (fat, carbohydrate, protein and alcohol) profiles of different diets.

The Metabolism and the Respiratory Quotient of Excised Renal Tissue.

Experimental Biology and Medicine, 1926
Conclusions1. It is shown by complete double respiratory quotients that in the case of renal tissue, the error of the Warburg-Barcroft manometers is, on the average, ±0.014.2. The quotients were all between 0.7 and 1.0, and are fully accounted for by the oxidation of foodstuffs, without postulating the transformation of one into another.3. As evidenced
