Body shape and body size are hugely important for the understanding of multiple ecological phenomena. In order to study and compare sizes across taxa and to understand the ecological significance of shape differences, there is a need for ways to ‘translate’ different size measurements to a common metric. Body mass is the most useful such common index for size across taxa. Based on a large (4900...

Let P be a poset (partially ordered set), i.e., a set equipped with a relation<where x < y implies y 6< x and x < y, y < z implies x < z. The relation≤ as usual means x = y or x < y. For details on the theory of posets we refer the reader to [6,7]. In these texts further references are supplied as well. Let w : P → R be a weight function on the elements of P , where R is the set of all real num...

some growth parameters of pea (cv. pleven 4) and vetch (cv. obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the institute of forage crops, pleven, bulgaria. humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. ratios of aboveground weight t...

Prevalences of malnutrition and overweight among children under five years and its association with socioeconomic, demographic and health indicators were estimated for the six largest municipalities of Maranhão, in 2006/2007. By means of a household survey, a sample of 1214 children under five years of age was randomly selected. Two-stage cluster sampling was used, representing the six municipa...
