We examine the scaling law BJMa which connects organismal resting metabolic rate B with organismal mass M, where a is commonly held to be 3/4. Since simple dimensional analysis suggests a"2/3, we consider this to be a null hypothesis testable by empirical studies. We re-analyse data sets for mammals and birds compiled by Heusner, Bennett and Harvey, Bartels, Hemmingsen, Brody, and Kleiber, and ...

We derive sufficient conditions for the cross-correlation coefficient of a multivariate spatial process to vary with location when the spatial model is augmented with nugget effects. The derived class is valid for any choice of covariance functions, and yields substantial flexibility between multiple processes. The key is to identify the cross-correlation coefficient matrix with a contraction m...

Individual resource intake rates are known to depend on both individual body size and resource availability. Here, we have developed a model to integrate these two drivers, accounting explicitly for the scaling of perceived resource availability with individual body size. The model merges a Kleiber-like scaling law with Holling functional responses into a single mathematical framework, involvin...

Different approaches examine discourse markers: descriptive and formal approaches (quantitative or qualitative, synchronic or diachronic) connectives and discourse markers. This article presents a study case of discourse markers used in unacceptable way from a grammatical and cohesion point of view in a learning environment. Two questions will be discussed: Are these type of use produce reading...

Glucose of the blood has been considered to be the major source of the carbon of lactose in milk, and recent studies with labeled glucose have substantiated this conclusion. Kleiber et al. (1) injected’ glucose-U-C4 intravenously into a lactating cow and found approximately 50 per cent of the Cl4 converted to milk lactose. They calculated that about four-fifths of the lactose carbon originated ...

introduction: the genetic characterization of local breeds of sheep is of paramount importance, not only for conservation purposes but also for the definition of breeding objectives and breeding programmes. when records are nonexistent and breeds are not well defined in the field, information could be obtained from research station information where pedigree and performance records have been ke...

In this paper we describe block algorithms for the reduction of a real symmetric matrix to tridiagonal form and for the reduction of a general real matrix to either bidiagonal or Hessenberg form using Householder transformations. The approach is to aggregate the transformations and to apply them in a blocked fashion, thus achieving algorithms that are rich in matrix-matrix operations. These red...
