The Alperin–McKay conjecture relates height zero characters of an $$\ell $$ -block with the ones its Brauer correspondent. This has been reduced to so-called inductive conditions about quasi-simple groups by third author. validity those is still open for Lie type. present paper describes in -blocks type over a field q elements when divides $$q-1$$ . We also give information and correspondents. ...

Abstract A comprehensive radiological survey was carried out in an open-cut slate stone quarry. The activity of 226 Ra, 228 Ra and 40 K the ore samples were measured as 38 ± 5, 41 6 869 52 Bq kg 1 , respectively. Outdoor radon indoor concentrations from 37 7 to 193 11 m ?3 (77 8 ), 49 253 23 (131 13 average outdoor gamma dose 116 84 nSv h ? annual effective doses estimated between 1.0 0.1 3.3 0...

Evolutionary Psychology has considered a Fast Life History Strategy (FLHS), denoting an individual’s tendency to invest more resources in proliferation than child-rearing, be responsible for the emergence of aversive traits. Empirical evidence this notion been inconsistent, however. Herein, we teste...

BACKGROUND Transforming growth factor-beta 1(TGF-β1) is involved in the development of acute rejection (AR) episodes in solid organ transplant recipients; and a number of studies have been conducted to investigate the combined effects of human TGF-β1 gene (TGFB1) +869 T/C and +915 G/C polymorphisms on AR risk. However, the results obtained are inconclusive. METHODS Eligible studies that inves...

The striatum plays a major role in both motor control and learning and memory, including executive function and "behavioral flexibility." Lesion, temporary inactivation, and infusion of an N-methyl-d-aspartate (NMDA)-receptor antagonist into the dorsomedial striatum (dmSTR) impair reversal learning in adult rats. Systemic administration of MK-801 disrupts reversal learning in developing rats, a...

BACKGROUND The immune system has been implicated in the pathogenesis of certain clinical manifestations of parvovirus B19 infection, including rash and arthralgia. Cytokines feature in the pathogenesis of parvovirus B19 infection, so inherited variability in cytokine responses to B19 infection might have a bearing on the symptomatology of parvovirus B19 infection. AIMS To investigate the poss...

Poor understanding of the topography of cyclic nucleotide (CN) phosphodiesterase (PDE) catalytic sites compromises development of potent, selective inhibitors for therapeutic use. In the X-ray crystal structures of the catalytic domains of some PDEs, an invariant glutamine hydrogen bonds with groups at C6 and N1 or N7 on catalytic products or analogous positions of some inhibitors, inferring si...

This paper presents an approach to approximate the forward and inverse dynamic behaviours of a magnetorheological (MR) damper using evolving radial basis function (RBF) networks. Due to the highly nonlinear characteristics of MR dampers, modelling of MR dampers becomes a very important problem to their applications. In this paper, an alternative representation of the MR damper in terms of evolv...
