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 ...

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.

Nitrogen and energy partitioning in two genetic groups of pigs fed low-protein diets at 130 kg body weight [PDF]
, 2015 The aim was to evaluate the effect of low-protein (LP) or low-amino acid diets on digestibility, energy and nitrogen (N) utilisation in 2 genetic groups (GG) of pigs (129±11 kg BW). Duroc×Large White (A) pigs were chosen to represent a traditional GG for
