This study investigates the effects of oxide traps induced by SOI of various thicknesses (TSOI = 50, 70 and 90 nm) on the device performance and gate oxide TDDB reliability of Ni fully silicide metal-gate strained SOI MOSFETs capped with different stressed SiN contact-etch-stop-layer (CESL). The effects of different stress CESLs on the gate leakage currents of the SOI MOSFET devices are also in...

Morteza Eighani, Seyed Yousef Paighambari,

The performance of a square mesh panel (90 mm stretched mesh size) on reducing the catch of immature Psettodes erumei Bloch and Schneider, 1801 smaller than Lm50% value was tested in a small-scale shrimp-trawl fishery along Hormuzgan coasts in the The Persian Gulf. During shrimp season, 25 trawl hauls were carried out and a total of 371 P.erumei was caught in the codend and cover net. Length ra...

Approximately 80-90% of the norepinephrine released in the brain or in peripheral tissues is taken up again through the neuronal norepinephrine transporter (NET). Pharmacological studies with NET inhibitors showed that NET has opposing effects on cardiovascular sympathetic regulation in the brain and in the periphery. Furthermore, NET is involved in the distribution of sympathetic activity betw...

background: stress is a nonspecific reaction to everything the body needs. although occupational stress exists in every occupation, it is seen with more frequency and intensity amongst those occupations related to human health. in this study, we aimed to investigate the level of occupational stress in operating room staffs working in the hospitals affiliated to isfahan university of medical sci...

To study the effects of both drought stress and seed zinc and iron concentrations on the photosynthesis, chlorophyll fluorescence, and proline and carbohydrate accumulations in soybean (Glycine max (L.) Merr. cv. M9) leaf, a split plot experiment was carried out in 2012 based on a randomized complete block design with three replications in greenhouse conditions at Yasouj University. Drought str...

‏ بر اساس نظریه ی تکامل، همه ی موجودات زنده روی کره ی زمین با یکدیگر مرتبط بوده و از نیای مشترکی به وجود آمده ‏ند. یکی از پیشرفت های مهم در زیست شناسی تکاملی، طی چند دهه ی اخیر، یافتن روشی برای تعیین الگوی نیاکانی میان ‏جانداران است. این روش که فیلوژنتیک نام گرفته، امکان رد یابی تاریخ موجودات زنده را با دقت بیشتری فراهم نموده است. ‏مدل های مختلف درخت فیلوژنتیک معمولا تکامل تنها یک ژن برای موجود...

This study was conducted in order to investigate the effect of drought stress and Azomite fertilizer on some physiological traits of two tomato (Lycopersicon esculentum M.) cultivars (izmir and Izabella). A randomized complete design with factorial arrangement with three replications was used. Treatments consisted of three levels of irrigation including FC (control), FC (mild drought stress), a...

Genetic selection for body temperature during heat stress might be a useful approach to reduce the magnitude of heat stress effects on production and reproduction. Objectives of the study were to estimate the genetic parameters of rectal temperature (RT) in dairy cows in freestall barns under heat stress conditions and to determine the genetic and phenotypic correlations of rectal temperature w...

distinguishing productive zones of a drilled oil well plays a very important role for petroleum engineers to decide where to perforate to produce oil. conventionally, net pay zones are determined by applying a set of cut-offs on perophysical logs. as a result, the conventional method finds productive intervals crisply. in this investigation, a net index value is proposed, then; diffusivity equa...
