Insulation reduces heat exchange between a body and the environment. Glabrous (nonhairy) skin surfaces (palms of the hands, soles of the feet, face, and ears) constitute a small percentage of total body surface area but contain specialized vascular structures that facilitate heat loss. We have previously reported that cooling the glabrous skin surfaces is effective in alleviating heat stress an...
OBJECTIVE To examine the effect of cooling the skin with an ice jacket before and between exercise bouts (to simulate quarter and half time breaks) on prolonged repeat sprint exercise performance in warm/humid conditions. METHODS After an initial familiarisation session, seven trained male hockey players performed two testing sessions (seven days apart), comprising an 80 minute intermittent, ...
در این پروژه فیلترهای مایکرواستریپ جدیدی برای بهدست آوردن اندازهی فشرده، پاسخ تیز و نیز باند قطع عریض ارائه شده است که از جملهی آن ها فیلتری است که از سری شدن یک رزوناتور شاخهای منتهی به نیمدایره و یک تکهی شعاعی بهبود یافته به عنوان تضعیف کنندهی هارمونیک، تشکیل شده است. فرکانس قطع -3 db این فیلتر در 1.54 ghz قرار دارد. باند گذر این فیلتر تنها 0.26 ghz است که شامل محدودهی فرکانسی 1.5...
Cooling and hypothermia are profoundly neuroprotective, mediated, at least in part, by the cold shock protein, RBM3. However, the neuroprotective effector proteins induced by RBM3 and the mechanisms by which mRNAs encoding cold shock proteins escape cooling-induced translational repression are unknown. Here, we show that cooling induces reprogramming of the translatome, including the upregulati...
assigning premium to the insurance contract in iran mostly has based on some old rules have been authorized by government, in such a situation predicting premium by analyzing database and it’s characteristics will be definitely such a big mistake. therefore the most beneficial information one can gathered from these data is the amount of loss happens during one contract to predicting insurance ...
به منظور بررسی تاثیر پروبیوتیک و سطوح مختلف پودر صمغ آنغوزه در مقایسه با آنتی بیوتیک (آویلامایسین) بر عملکرد رشد، وزن نسبی اندام های داخلی، میکروفلور روده، مورفولوژی پرزهای روده، کیفیت گوشت و تیترآنتی بادی بر علیه گلبول قرمزگوسفندی در جوجه های گوشتی، آزمایشی در قالب طرح کاملا تصادفی با 6 تیمار به اجرا درآمد. تیمارهای آزمایشی شامل: جیره پایه بدون افزودنی، جیره پایه حاوی 100 میلی گرم در کیلو گرم ...
Rotating accretion flow may undergo centrifugal pressure mediated shock transition even in presence of various dissipative processes, such as viscosity and cooling mechanism. The extra thermal gradient force along the vertical direction in the post shock flow drives a part of the accreting matter as bipolar outflows which are believed to be the precursor of relativistic jets. We compute mass lo...
in islamic republic of iran, the heating and cooling of buildings account for approximately 40% of total energy use. from the entire energy loss taking place in a building, one third of that energy loss occurs through the windows. many of today’s existing buildings are not energy efficient, and consume more energy than is needed in order to make the working and living environments comfortable. ...
