Plasma thyroxine (T4), triiodothyronine (T3) and iodide levels were measured from birth until 30 days of age in 17 Holstein x Friesian (HF), 7 Salers and 7 Charolais calves born at term. The response of plasma T4 and T3 levels to bovine thyrotropin (TSH) injection was also compared in two groups of 9 HF calves 3hrs and 21 days, respectively, after birth. In the HF calves, plasma T4 and T3 level...

In many aquatic environments elevated levels of trace elements occur due to anthropogenic activities. Water organisms can be precise indicators in estimating the status of pollution of water environments. Among them several species of fish have been widely used (Håkanson 1984, Chevreuil et al. 1995, Andres et al. 2000, Falandysz et al. 2000, Perkowska and Protasowicki 2000, Řehulka 2001, Wagner...

The variation in animal mating systems has received a great deal of attention from behaviorists and evolutionary biologists alike (Shuster & Wade 2003). Polyandry, the mating of a single female with multiple males, is evolutionarily derived (Hughes et al. 2008) and relatively rare in social insects (Strassmann 2001). Modest polyandry has evolved in Vespula wasps (Ross 1986; Foster & Ratnieks 20...

The American Clinical Magnetoencephalography Society (ACMEGS) is a professional society of physicians and other professionals with doctoral degrees “involved in clinical use of magnetoencephalography (MEG), electroencephalography (EEG), magnetic resonance imaging, or computerized axial tomography” (ACMEGS, Inc, Bylaws, 2006). The ACMEGS is primarily focused on advancing clinical applications of...

1. introduction current statistical methods may be unable to accurately predict recurrence intervals of rare, large magnitude floods. the usual procedure involves extrapolation from gauged hydrological records documenting 30–40 year records of observed (normally small) floods to the estimation of the quantifies and recurrence intervals of very large, rare floods. this conventional approaches be...

There has been a considerable amount of research in the past 40 years into the effects of noise on the performance of school children (Hetu et al. 1990; Evans & Lepore 1993; Shield & Dockrell 2003). It is generally accepted that noise has a detrimental effect upon the learning and performance of primary school children, and that the older children in this age group are more affected than the yo...

plexity. This conclusion is conceptually similar to our own, and it little alters the broader impacts of our published findings; still, the general relevance of the issues warrants a response. In their reanalysis, Gutierrez-Ibanez et al. [2016] perform a ‘residual analysis’, which regresses body weight on brain weight with phylogenetic generalized least squares (PGLS) to obtain size-corrected r...

The new River Water Quality Model no.1 introduced in the two accompanying papers by Shanahan et al. (2000) and Reichert et al. (2000) is comprehensive. Shanahan et al. (2000) introduced a six-step decision procedure to select the necessary model features for a certain application. This paper specifically addresses one of these steps, i.e. the selection of submodels of the comprehensive biochemi...
