the aims of this research were to estimate of genetic parameters for pre-weaning traits and lamb survival in iran-black sheep. for this purpose 6344 records for birth weight (bw) and lamb survival (ls) and 5264 records for weaning weight (ww), average daily gain (adg) and kleiber ratio (kr) were available, which collected by abbasabad animal breeding and rearing station, over the period from 19...

Report on three homicides, in which apart from other kinds of mechanical traumas there were also injuries due to stabs with a screwdriver; in one case a screwdriver with a cross-shaped tip was used; in the two other cases the weapon was a regular blade screwdriver with a single-edged tip. Supplementing the systematic studies by Brinkmann and Kleiber (Arch. Kriminol. 161, 31-40 [1978]) several o...

A multiple regression analysis of several factors influencing basal metabolic rate (BMR) was performed using data for 223 subjects from the classic metabolism studies published by Harris and Benedict in 1919. These data had previously been analyzed by Kleiber using metabolic body size, the three-fourths power of body mass, as a predictor of BMR. His prediction equations were separated by sex an...

Introduction In 1961 Max Kleiber published the book The Fire of Life [1]. It is still one of the classics in the field of animal and human bioenergetics. In his book he focussed on the parallel between animal and human life and fire, emphasizing the generalizations of biophysics rather than the differentiations of biochemistry. Life involves much more than chemical potential, work and heat. Mod...

It is generally accepted that feed intake and growth (gain) are the most important economic components when calculating profitability in a growth test or feedlot. We developed a single post-weaning growth (feedlot) index based on the economic values of different components. Variance components, heritabilities and genetic correlations for and between initial weight (IW), final weight (FW), feed ...

Coherent quantum effects have been confirmed for several biological processes. These processes exist in the environment of a warm wet cell where decoherence can be a serious concern. Here we propose a mechanism whereby quantum coherence may extend through the water matrix of a cell. The model is based on coherent waves of established ultrafast energy transfers in water. Computations based on th...

We examine the scaling law B is proportional to M(alpha)which connects organismal resting metabolic rate B with organismal mass M, where alpha is commonly held to be 3/4. Since simple dimensional analysis suggests alpha = 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, He...
