advanced high strength steels (ahss) have recently attracted great attention because of their superior mechanical properties. a modern group of these steels, known as twinning induced plasticity (twip) steels, shows a unique combination of strength and ductility even at high rates of strain. in order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...

male guinea pigs show high susceptibility to burkholderia mallei and have been used as animal models in glanders studies. the purpose of our study was to elucidate glanders comparative pathogenesis in guinea pigs. we present here the histological changes and bacterial isolation that develop over time in guinea pigs inoculated intraperitoneally (ip) with two strain of b. mallei. ten male guinea ...

introduction: physiological, anthropometrical and thermal perceptual are the most important factors affecting thermoregulation of men and women in workplaces. the purpose of this study was determining the validity of a questionnaire method for assessing women’s heat strain in workplaces. methods: this cross‑sectional study was carried out on 96 healthy women. data were continuously collected ov...

conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...

biomechanical properties of soft tissue, such as liver, are important in modeling computer aided surgical procedures. experimental evidences show that liver tissue is transversely isotropic. in this article, considering the liver tissue as an incompressible fiber-reinforced composite with one family of fibers, an exponential strain energy function (sef) is proposed. the proposed sef is based on...

probiotics, living microorganisms which when used in adequate amounts, have health benefits on the host, have attracted a considerable deal of interest in the biotechnology market. various prokaryotic and eukaryotic microbes have been studied for probiotic purposes in human and animals. lactobacillus and bifidobacterium are the main probiotic genera; however, there are reports on the probiotic p...

background nursing teachers have difficulties fulfilling multiple roles expectations and balancing the various dimensions of their roles that may lead to role strain. in order to lack of culturally and academically proper scale in iran to measure role strain in nursing teachers, localizing a foreign scale in this field is necessary. objectives the objective of this study was psychometric evalua...

conclusions: left ventricular systolic heart failure, may result in inter and intra-atrial asynchrony even in clinically stable patients without significant pulmonary hypertension and diastolic dysfunction. results: in heart failure patients either inter or intra-atrial asynchrony were far more common in comparison with normal subjects (p=0.008 and p=0.007 respectively). patients and methods: t...
