Abstract The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique particularly suitable a pixelated charge readout time projection chambers, given large number channels that this technology employs. Here we present first full microphysi...
امروزه ، مرفولوژی اسپرم بعنوان یکی از پارامترهای مهم نمونه های انزالی مطرح می باشد. تعیین دقیق مرفولوژی طبیعی اسپرم که بخشی از آنالیز سیمن را شامل می شود در تعیین روش درمانی مناسب جهت زوج نابارور نقش بسزایی دارد. هدف اصلی این مطالعه تجربی مقایسه روشهای رنگ آمیزی (h and e)hematoxylin-eosin,crystal violet و روش wet با رنگ آمیزی geimsa (who) در تعیین مرفولوژی اسپرم انسانی بوده است .
The small-animal High-Resolution SPECT (HiReSPECT) is a dedicated dual-head gamma camera recently designed and developed in our laboratory for imaging of murine models. Each detector is composed of an array of 1.2 × 1.2 mm(2) (pitch) pixelated CsI(Na) crystals. Two position-sensitive photomultiplier tubes (H8500) are coupled to each head's crystal. In this paper, we report on a resolution-recov...
Geometrical design of the spiral crystal selector can affect crystal orientation in the final single crystal structure. To achieve a better understanding of conditions associated with the onset of crystal orientation in a spiral crystal selector, temperature field was investigated using three-dimensional finite element method during the process. Different geometries of spiral crystal selec...
Introduction: Crystal meth by induction of free radical formation in brains cells and lipid peroxidation cause to the apoptosis. The aim of present study is to investigate the effect of extract of Scrophularia striataon spatial memory, lipid peroxidation and alteration of antioxidant enzymes levels. Methods: In this experimental study, 42 male Wistar rats were divided into 6 groups, including:...
