The goal of this project is to comprehensively model the activity-travel patterns of workers as well as non-workers in a household. The activity-travel system will take as input various land use, socio-demographic, activity system, and transportation level-of-service attributes. It will provide as output the complete daily activity-travel patterns for each individual in the household. In additi...
بررسی برهمکنش بین میسلی مخلوط مواد فعال سطحی کاتیونی و غیر یونی به کمک روشهای ولتامتری و پتانسیومتری
در این تحقیق از روش ولتامتری چرخه ای به منظور بررسی برهمکنش بین میسلی، مطالعه ساختاری و محاسبه شعاع هیدرودینامیکی میسل ها درمخلوط دوتایی مواد فعال سطحی استفاده شد. ضریب نفوذ میسلی در مخلوط مواد فعال سطحی کاتیونی ستیل تری متیل آمونیوم برماید (ctab) ، ستیل پیریدینیوم برماید (cpb) ، ستیل پیریدینیوم کلراید (cpc) با ماده فعال سطحی غیر یونی 100- tx توسط این روش اندازه گیری شد و با استفاده ازنظریه بره...
Stem cells are extensively used for regenerative purposes as they unspecialized capable of renewal and differentiation. Growth factors like vascular endothelial growth factor (VEGF) play a crucial role in enhancing the potential stem cells. The present study was designed to elucidate effects VEGF preconditioning accelerating adipose-derived (ADSCs) wound healing. In vivo carried out using femal...
We determined the capacity of transplanted beta cells to modify their replication and mass when stimulated by changes in metabolic demand. Five groups of Lewis rats were studied: group 1 (Tx-Px) had a 95% pancreatectomy 14 d after transplantation of 500 islets; group 2 (Px-Tx) had a 95% pancreatectomy 14 d before transplantation of 500 islets; group 3 (Tx) was transplanted with 500 islets; grou...
background: this cross sectional study was conducted to evaluate the effect of &gamma-rays; and electron-beam irradiation with a commercial toxin binder-milbond-tx on the performance, feed components, and meat quality of japanese quails challenged with aflatoxin b1. methods: overall, 168 one-d-old chicks (japanese quails) were allocated to eight treatments with three replicates based on a compl...
0. Introduction In [1], gravitational anomaly cancellation formulas are derived from direct computations. In particular, in dimension 12, the Alvarez-Gaumé and Witten ‘‘miraculous cancellation’’ formula can be written as {L(TX, ∇TX )}(12) = {8A(TX, ∇TX )ch(TCX, ∇TCX )}(12) − 32{A(TX, ∇TX )}(12), (0.1) where X is a twelve-dimensional Riemannian manifold, ∇TX is the associated Levi-Civita conn...
Mobile network operators demand small base station antennas and high physical layer throughputs. In the downlink, high physical layer throughputs can be achieved by exploiting transmit diversity. Given that the correlation between different propagation paths reduces the achievable throughput, it is commonly conjectured that the greater the transmit antenna spacing, the better the radio link per...
In this paper the influence of the channel estimation error on the performance of the closed loop Tx diversity algorithms for WCDMA is studied for high number of Tx antennas. The analysed algorithms are recently proposed generalised closed loop Tx diversity, allantenna Tx diversity and one-antenna selection Tx diversity. It was shown that generalised closed loop Tx diversity algorithm is more r...
زمینه و هدف: این مطالعه با هدف ارزیابی تأثیر کاربرد دو نوع پرایمر روی بیس براکت، بر قدرت باند برشی (sbs) و نحوه شکست باند انجام گرفت. روش بررسی: در این مطالعه 75 دندان کشیده شده پرمولر انسان به سه گروه مساوی تقسیم شدند؛ گروه 1 (کنترل): در این گروه براکت ها پس از آماده سازی سطح مینا به روش معمول (اسید اچ + پرایمر) توسط کامپوزیت لایت کیور transbond xt باند شدند. گروه 2 (tx) : در این گروه نیز بر...
