Experiments were performed in order to check whether biological activity of some organophosphorous compounds widely applied as herbicides: 2,4-dichlorophenoxyacetic acid (1) and its sodium salt (2), N-phosphonomethylglycine acid (3) and its sodium salt (4), diethyl 1-butylamino-1-cyclohexanephosphonate (5) and diethyl 9-butylamino-9-fluorenephosphonate (6) followed from their oxidative activity...
The effects of halothane and diethyl ether on the regenerating liver following 70 per cent hepatectomy were studied in Fisher/344 (F) rats. Our aim was to discover whether halothane administered repeatedly and over prolonged periods could influence the liver regenerative process or hepatocyte function. We also wished to know if the effects of halothane differed from those of diethyl ether. We f...
Detection and Quantitative Analysis for 2-Thiobarbituric Acid Utilizing Uv-Visible Spectrophotometer
Sulfated silica (SO4/SiO2) and nickel impregnated sulfated (Ni-SO4/SiO2) catalysts have been successfully carried out for the conversion of ethanol into diethyl ether (DEE) as a biofuel. The aims this research were to study effects acidity on SO4/SiO2 Ni-SO4/SiO2 in ether. This focuses increases activity selectivity SiO2 with impregnation sulfate Ni metal, which had good less expensive. prepare...
Introduction: Irradiation treatment is one of the best techniques to extend the shelf-life of meat, without emerging the nutritional properties and sensory quality of irradiated meat products. However electron -beam may cause transformations in foods but has been known as to the most easily-applied irradiation technique in food industries. Electron-beam irradiation is an environment...
Introduction: Irradiation of intervention strategies in order to effectively control food-borne pathogens are microorganisms that reduce microbial load and increase the shelf-life. Methods: In this study, ostrich meat with electron beam 1.5, 3 and 5 kGy doses treated and were stored in temperature 1 ± 4° C for 15 days. With 5 day intervals after irradiation, chemical and organolep...
سنتز پلیمرهای کوئوردیناسیونی جدید از لیگاندهای 2-آمینو نیکوتینیک اسید، 2-کینولین کربوکسیلیک اسید، 2-پیرازین کربوکسیلیک اسید در ابعاد توده، با روش گرایان دمایی و با استفاده از شاخه ی جانبی انجام شده است، این پلیمرها توسط روش طیف سنجی ir شناسایی و پایداری گرمایی آن ها توسط تجزیه های وزن سنجی حرارتی (tga) و تجزیه ی گرمایی تفاضلی (dta) بررسی شده است. در ادامه، ساختار این ترکیبات توسط بلورنگاری پرتو...
