this study provides new data on chromosomal characteristics and dna barcoding of three endemic loaches of iran: spiny southern loach cobitis linea (heckel, 1847), persian stream loach oxynoemacheilus persa (heckel, 1848) and tongiorgi stream loach oxynoemacheilus tongiorgii (nalbant & bianco, 1998). the chromosomes of these fishes were investigated by examining metaphase chromosome spreads ...
the growth hormone receptor (ghr) is a member of cytokine/hematopoietin family that mediates the biological actions of growth hormone (gh) on target tissues. therefore, the purpose of this study was to examine the association of tg-repeat polymorphisms in the 5’-flanking region of bovine ghr gene with milk production traits and somatic cell score (scs) in holstein cattle of iran. the part of 5’...
cauda equina syndrome (ces) although uncommon, is a very serious condition, which should be diagnosed as soon as possible. urinary dysfunction following a lumbosacral trauma is a key for the physician to consider ces as the most probable diagnosis. up to 62% of ces patients report a recent episode of trauma. we herein report a young man with ces due to sacral fracture with an interesting imaging.

accurate estimation of evaporation is important for design, planning and operation of water systems. in arid zones where water resources are scarce, the estimation of this loss becomes more interesting in the planning and management of irrigation practices. this paper investigates the ability of artificial neural networks (anns) technique to improve the accuracy of daily evaporation estimation....
میکروآران ای ها یک کلاس از آران ای های کوچک غیرکدشونده تنظیمی هستند که اهمیت بسیار زیادی در خاموش کردن ژن های پست-ترنسکریپشنال دارند. آن ها اکثراً با چسبیدن به بخش 3’utr( three prime untranslated region) مسنجر آران ای های هدف، میزان ژن ها را به یکی از دو روش بریدن یا مهار کردن تنظیم می کنند. دانشمندان در ابتدا اهداف میکرو آر ان ای ها را با انجام آزمایش مشخص می کردند. با این وجود، به خاطر پرهزینه...
روشهای عددی مانند روش هم محلی، گالرکین و تربیع برای حل معادلات انتگرالی فردهلم در نهایت به حل یک دستگاه معادلات خطی یا غیر خطی جبری منجر می شوند که حل این دستگاهها اغلب از نظر زمانی و دقت در محاسبه جواب با مشکل مواجه می شوند. در این رساله روش هایی ترکیبی را بر مبنای الگوریتم ابتکاری الکترومغناطیس و روش gmres را برای غلبه بر این قبیل از مشکلات در حل این دستگاه معادلات ارائه نموده ایم. الگوریتم...
