با توجه به ناکارامدی روش های اختلالی در پلاسمای حاضر که یک پلاسمای قویا جفت شده می باشد ، در بررسی پلاسمای مذکور از یک رویکرد جدید به نام ads/cft استفاده می شود. دانشمندان معتقدند فاز کلی جهان خلقت در چند میلیونیوم اول پس از انفجار بزرگ به صورت همین پلاسما بوده است ، لذا کسب اطلاعات در مورد آن می تواند اطلاعات ارزنده ای در مورد خلقت جهان به ما بدهد. موضوع این تحقیق ، بررسی حرکت یک کوارک و یک مز...
This study focuses on performance of H-shaped steel beams to CFT column rigid connections. To this end, the effects of internal and external stiffeners on hysteretic behavior of connections were studied. Comparative numerical analyses carried out on eight different connections. To this end finite element models were prepared using ANSYS and nonlinear cyclic analyses carried out. Results of this...
جنس thymus متعلق به تیره نعنا بوده و بالغ بر 215 گونه از آن در سراسر جهان یافت می شود. این جنس در ایران 18 گونه معطر چند ساله دارد که از میان آنها 4 گونه انحصاری ایران هستند. اسانس آویشن(thymus spp.) با دارا بودن ترکیبات با ارزشی همچون تیمول و کارواکرول از جایگاه ویژه ای برخوردار می باشد. پس از کشت اکسشن های مختلف گونهthymus pubescens در ایستگاه تحقیقات گیاهان دارویی استان واقع در گردفرامرز شا...
CONTEXT During aging, total testosterone (TT) declines and SHBG increases, resulting in a greater decrease in calculated free T (cFT). Currently, guidelines suggest using TT to diagnose androgen deficiency and to reserve cFT only for men with borderline TT. OBJECTIVE Our objective was to investigate if either low cFT or low TT is more strongly associated with androgen-related clinical endpoin...
Introduction: Due to the unwanted effects of the migraine headaches of the patient and the role played by excitement and stress in the development and exacerbation of such headaches, migraine headaches are considered among psychosomatic disorders affecting the psychological life of the patients. The present study aimed to investigate the effectiveness of compassion-focused therapy (CFT) for imp...
a comparison between design codes i.e. aci and aisc-lrfd in evaluation of flexural strength of concrete filled steel tubular columns (cfts) is examined. for this purpose an analytical study on the response of cfts under axial-flexural loading is carried using three-dimensional finite elements with elasto-plastic model for concrete with cracking and crushing capability and elastoplastic kinemati...
Calcifying fibrous tumor (CFT) is a recently recognized rare benign lesion characterized by dense hyalinized collagenous tissue with interspersed spindle cells and a lymphoplasmocytic infiltrate. Calcification is the hallmark of CFT and may present in the form of psammomatous bodies or dystrophic calcifications. CFT of the intestinal tract is uncommon and rectal CFT has never been reported. Rec...
It has been conjectured that the (weakly coupled) Randall-Sundrum (RS) model with gauge fields in bulk is dual to a (strongly coupled) 4D conformal field theory (CFT) with an UV cutoff and in which global symmetries of the CFT are gauged. We elucidate features of this dual CFT which are crucial for a complete understanding of the proposed duality. We argue that the limit of no (or small) brane-...
calcifying fibrous tumor (cft) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. cft of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric cfts reported in english literature. this benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...
