سابقه و هدف: سلامت خاک از مولفه ‏های اصلی در دستیابی به سامانه ‏‏های کشاورزی پایدار بوده که شدت تحت تاثیر عملیات زراعی مانند خاکورزی قرار می ‏گیرد. را توان با استفاده پارامترهای فیزیکی، شیمیایی بیولوژیکی قالب الگوریتم‏ های مشخص کمّی کرد. نتیجه، بررسی وضعیت کیفی باروری مدیریتی مختلف زمین جهت استقرار مناسب برای تولید بهینه نظام‌های امری ضروری می‏ باشد. چارچوب ارزیابی مدیریت SMAF 1 عنوان ابزاری قدر...

ابتلای یکی از اعضای خانواده به بیماری مزمن، بر روابط، نقش‌ها، سلسله مراتب و به‌طور کلی سیستم تأثیر می‌گذارد را برای مدیریت سازگاری با شرایط جدید، چالش‌هایی مواجه می‌کند. هدف این مرور ادبیات پژوهشی، شناسایی مسائلی است که در مزمن اعضا، آن رو‌به‌روست. بدین منظور، بررسی نظام‌مند مقالات چاپ‌شده زبان فارسی یا انگلیسی مجلات داخلی خارجی سال 201۴ (دی ۱۳۹۲) تاکنون، پایگاه‌های SID، Magiran، Google Scholar...

Our investigations started with the question, why are there so many VEGF isoforms? One possibility that was considered was that some isoforms may interact with receptors other than VEGFR1 and VEGFR2, the only VEGF receptors known at that time. Cross-linking studies using labeled VEGF165 and human umbilical vein endothelial cells (HUVEC) revealed two crosslinking products that were missing in cr...

INTRODUCTION Factor concentrates are currently available and becoming increasingly used off-label for treatment of bleeding. We compared recombinant activated factor VII (rFVIIa) with three-factor prothrombin complex concentrate (3F-PCC) for the ability to augment thrombin generation (TG) in neonatal plasma after cardiopulmonary bypass (CPB). First, we used a computer-simulated coagulation mode...

Some theoretical aspects of 3-flavour (3f) neutrino oscillations are reviewed. These include: general properties of 3f oscillation probabilities; matter effects in νμ ↔ ντ oscillations; 3f effects in oscillations of solar, atmospheric, reactor and supernova neutrinos and in accelerator long-baseline experiments; CP and T violation in neutrino oscillations in vacuum and in matter, and the proble...

The Hyers-Ulam stability, the Hyers-Ulam-Rassias stability, and also the stability in the spirit of Gǎvru̧ta for each of the following quadratic functional equations f(x+y)+ f(x−y) = 2f(x)+ 2f(y), f(x+y + z)+ f(x−y)+ f(y − z)+ f(z−x) = 3f(x)+3f(y)+3f(z), f (x+y+z)+f(x)+f(y)+f(z)= f(x+y)+f(y+z)+f(z+x) are investigated. 2000 Mathematics Subject Classification.

In the Chinese hamster lung cell line DC-3F/9-OH-E, selected for resistance to 9-OH-ellipticine and cross-resistant to other topoisomerase II inhibitors, the amount of topoisomerase IIalpha is 4-5-fold lower than in the parental DC-3F cells, whereas topoisomerase IIbeta is undetectable. Cloning and sequencing of topoisomerase IIalpha cDNAs from DC-3F and DC-3F/9-OH-E cells revealed an allele po...

Peripheral nerve growth is regulated by the coordinated action of numerous external stimuli, including positively acting neurotrophin-derived growth cues and restrictive semaphorin cues. Here, we show that Semaphorin 3F (Sema 3F) can antagonize nerve growth factor (NGF)-stimulated TrkA (tyrosine receptor kinase A) signaling in sympathetic neurons, thereby apparently contributing to growth cone ...
