The nature of scaling between the organismal basal metabolic rate B and its body mass M, BpM, is currently an important focus of debates in theoretical biology (Whitfield, 2001). For decades, it has been widely accepted that a1⁄4 3/4 for virtually all groups of organisms (Hemmingsen, 1960; Kleiber, 1961). A novel approach developed by West, Brown & Enquist (1997) (WBE) explains the value of a1⁄...

Lorsque l’on parcourt les principales investigations linguistiques sur le phénomène « métaphore », quel que soit le niveau d’analyse considéré (syntaxique, sémantique ou pragmatique), un premier constat s’impose : on assiste à des approches massives de la structure métaphorique nominale de caractérisation (SN1 + copule + SN2) tandis que peu d’attention est consacrée aux autres structures de la ...

Isotopes as tracers offer the possibifity of studying the kinetics of phosphate metabolism in the normal intact animal. Our aim in such a study on dairy cows is to describe the cow's phosphorus exchange by a system of quantitative terms, especially capacities and rates of exchange. According to the varying mobility, the total amount of phosphorus in the animal may be partitioned among a series ...
