This article reviews what is known about daily emergency department (ED) surge and ED surge capacity and illustrates its potential relevance during a catastrophic event. Daily ED surge is a sudden increase in the demand for ED services. There is no well-accepted, objective measure of daily ED surge. The authors propose that daily and catastrophic ED surge can be measured by the magnitude of the...
در این برنامه 229 نفر از افراد زیر 30 سال در زابل انتخاب شدند و نمونه خون جهت بررسی igg anti hav گرفته شد و جهت انجام آزمایش نمونه ها با حفظ زنجیره سرما به سازمان انتقال خون زاهدان فرستاده شد. در این بررسی از 229 نفر 117 نفر مونث (51/1 درصد) و 112 نفر مذکر (48/9 درصد) بودند. از کل جمعیت 203 نفر از نظر igg anti hav مثبت بودند (88/6 درصد) و 26 نفر igg anti hav در آنها منفی بود. فراوانی عفونت hav ...
This paper aims to measure and analyze of the leakage current of 20 kV polymer and porcelain metal oxide surge arresters under humid ambient conditions by applying different voltages to the arresters terminal. The characteristics of the leakage currents at that stage have been investigated when changes in the ambient humidity were introduced in an artificial fog chamber. It is assumed that magn...
Eye contact captures attention and receives prioritized visual processing. Here we asked whether eye contact might be processed outside conscious awareness. Faces with direct and averted gaze were rendered invisible using interocular suppression. In two experiments we found that faces with direct gaze overcame such suppression more rapidly than faces with averted gaze. Control experiments ruled...
The objective of this paper is to present the modeling and analysis of a 1.7 Mva SMES-based voltage sag corrector devices. The topology of the SMES-based system and its response to an upstream fault are described. This paper details various modeling aspects of the device including methods to generate a triangular signal and an internal reference voltage. Models to characterize the harmonic cont...
ایمونوتوکسینها برای درمان سرطان در حال توسعه هستند. آنها از آنتی بادیهای متصل به توکسین مانند اگزوتوکسین پسودوموناس تشکیل میشوند. از طرف دیگر فاکتور رشد اندوتلیال عروقی (vegf) در آنژیوژنزیس تومور نقش دارد و مهار vegfr-2 آنژیوژنزیس و رشد تومور را مهار میکند. هدف از این مطالعه تولید ایمونوتوکسین anti-vegfr2/rpe38، ارزیابی فعالیت سایتوتوکسیسیتی و مکانیسم عملکرد آن در in vitro بود. برای تولید ایمون...
Facing a recent surge in anti-natalist arguments saying that human procreation is immoral, some defend by procreative parenting adds meaning to parents’ life. This article examines one such defence, and argues it does not suffice rescue from the challenges procreation.
metal oxide surge arrester accurate modeling and its parameter identification are very important for insulation coordination studies, arrester allocation and system reliability. since quality and reliability of lightning performance studies can be improved with the more efficient representation of the arresters´ dynamic behavior. in this paper, big bang – big crunch and hybrid big bang – big cr...
