The ability to monitor usage of groups of workstations is quite useful for planning growth, facility hours, staffing and other issues; but in our case, both the format of the data (/var/adm/wtmp) and the fact that the data was spread over hundreds of different workstations made any analysis difficult at best. In this paper, we explore the use of a relational database to collect all the raw data...

The foetus is an allograft in the uterus. Yet it is not rejected by the immunocompetent mother. Understanding of the exact mechanism of foetal survival is limited and the unequivocal evidence still seems elusive. It is proposed that one of the possible reasons for evasion of maternal lymphocyte-mediated lysis by the foetus could be local inactivation of serine proteases, secreted on the target ...

Survival of the fetal allograft results from orchestrated adjustments in activity of maternal lymphoid cells as well as in trophoblast gene expression. One molecule that regulates uterine immune responsiveness is progesterone. In fact, uterine skin graft survival and susceptibility to bacterial infections are increased by progesterone. This review focuses on the role of progesterone in regulati...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...
