نانوچندسازه نیکل-کبالت هگزاسیانوفرات/گرافن (nicohcf/ergo) برای اصلاح خواص گرافن جهت کاربرد در ابرخازن¬ها تهیه گردید. به این منظور، الکترود فولاد ضدزنگ (ss) ارزان قیمت به عنوان بستر انتخاب گردید که دارای مقاومت در برابر خوردگی، هدایت الکتریکی و حرارتی بالا می¬باشد.گرافن اکسید (go) به روش اصلاح شده ی هامر تهیه شد. فولاد ضدزنگ به روش الکتروشیمیایی در محلول اسیدی با اعمال چگالی جریان a cm-2 5 صیقل ...
Abstract. A subgroup H of a group G is said to be SS-embedded in G if there exists a normal subgroup T of G such that HT is subnormal in G and H T H sG , where H sG is the maximal s- permutable subgroup of G contained in H. We say that a subgroup H is an SS-normal subgroup in G if there exists a normal subgroup T of G such that G = HT and H T H SS , where H SS is an SS-embedded subgroup of ...
Effects of sodium selenite (SS) in offspring of broiler breeders has been reported, but the comparison between SS and different level of methionine on offspring has received limited, so this study was conducted to investigate sodium selenite and methionine effects on concentration of selenium in egg and serum of Iranian native broiler breeders. An experiment was conducted in 3 × 3 factorial exp...
آب پنیر از جمله پسماندهایی است که دارای آلودگی بالا برای محیط زیست می باشد .بدین منظور لازم است با شناسایی مقدار کمی و کیفی از آلودگیهای ناشی جلوگیری شود.این پروژه با هدف بررسی میزان کاهش bod ،cod وss توسط عمل انعقاد شیمیایی بروی آب پنیر انجام شده است .بدین منظور آزمایشهای متفاوتی در دو بخش به ترتیب زیر صورت گرفته است 1( با استفاده از روش آزمایشگاهی2 (با استفاده از نرم افزار تاگوچی در بخش یک می...
Background: Septic shock (SS) is a health priority in sub-Saharan Africa. However, there is a dearth of data in this regard. Objective: This study aimed to determine the epidemiology, therapeutic patterns, outcome, and challenges in managing SS in a tertiary intensive care unit (ICU) of sub-Saharan Africa. Methods: The hospital file...
The effect of artificial insemination (AI), embryo transfer (ET) to bull dams (BD), and sexed semen (SS) to cow dams (CD) with and without controlling inbreeding were studied using stochastic simulation. Three levels of embryo transfer (no ET, ET on all BD, and ET on 20% of BD), five levels of sexed semen (no SS: control, SS-X on all CD, SS-X on 20% CD, SS-Y on all CD, and SS-Y on 20% CD), thre...
Let H be a subgroup of a finite group G. We say that H is SS-semipermutable in Gif H has a supplement K in G such that H permutes with every Sylow subgroup X of Kwith (jXj; jHj) = 1. In this paper, the Structure of SS-semipermutable subgroups, and finitegroups in which SS-semipermutability is a transitive relation are described. It is shown thata finite solvable group G is a PST-group if and on...
The synthesis of polyaniline doped with dodecylbenzene sulphonic acid (Pani-DBSA) coatings on 310 stainless steel (310 SS) surfaces has been investigated by using the galvanostatic method. The synthesized coatings were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), UV-Visible absorption spectrometry and Scanning Electron Microscopy (SEM...
The preparation of polyaniline/zeolite nanocomposite coating on 304 stainless steel (304 SS) surface has studied via the galvanostatic method. The electro-generated coating was characterized by Fourier transform infrared spectroscopy (FT-IR), UV-visible absorption spectroscopy, X-ray diffraction (XRD) patterns and scanning electron microscopy (SEM). The anticorrosion property of polyaniline/zeo...
