آنتی اکسیدان ها ملکول هایی هستند که می توانند رادیکال های آزاد واکنشگر را مهار کنند و از اکسیداسیون ملکول های دیگر جلوگیری نمایند، بنابراین در پیشگیری بیماری های مختلف نقشی اساسی دارند. بررسی ها نشان می دهد که علاوه بر ارزش تغذیه ای خرما، عصاره های این میوه توانایی زیادی در مهار رادیکال های آزاد به واسطه حضور ترکیبات آنتی اکسیدانی دارند. هدف از این مطالعه آنالیز آماری و بهینه سازی شرایط فرایندی...

We report the theoretical and experimental study of a temperature sensor based on the changing of the refractive index with the temperature in double core optical fibre. Because of it the coupling coefficient between two cores depends on temperature. This sensor uses the double core fibre directly as a temperature sensor as well to a data transmission. The influence of variations of the tempera...
In this study, the effects of some environmental storage conditions – light, temperature and humidity on the stability of the steroidal drug, hydrocortisone sodium succinate injection were investigated. The drug samples were stored at varying conditions of light, temperature (0C, 28C and 60C) and humidity, after which each sample was assayed at weekly intervals for their content of the drug usi...
abstract heated micaceous minerals under different commercial brand names (including vermiculite) are used as culture medium in greenhouses. heating minerals affects the release of elements, such as potassium, by changing their structure. the present study, investigates the ability of alfalfa, as one of the most important fodder around the world, to take up the non-exchangeable and structural p...
In this new year, energy urgency and climate debasement as a result of CO2 emanation consumption ozone layer has turned into fundamentally bigger problems to both industrially developed countries. solar operated thermoelectric refrigeration system, we can use Peltier modules which does not require refrigerants or other components like evaporators, compressors, condensers etc. Solar is used for ...
Electroimmunodiffusion, Chloroplast, C F r Content 1. Electroimmunodiffusion can be used for routine specific quantitative microdeterminations of photosynthetic ATP-synthase. The method has been worked out for samples of both the dissociated (C F ,) and the membrane bound enzyme (C F 0C F ,) . 2. Only a monospecific antiserum against C F , is required for relative determinations of C F] in any ...
A 29-year-old female patient with Ebstein anomaly was referred to our division for drugresistant symptomatic wide-complex tachycardia. Her preprocedural electrocardiograms showed a sinus rhythm without delta wave and a wide-complex short RP tachycardia with a rate of 150 bpm during palpitation. During conventional electrophysiologic study earliest local activation times during the tachycardia w...
The purpose of this study is to analyze the quality optical properties such as energy band gap thin layer tin oxide doped with aluminum, fluorine, indium, aluminum-fluorine, aluminum-indium, and aluminum-fluorine-indium. was synthesized using sol-gel spin coating method. ratio basic ingredients doping used in 95:5% 85:15%. that has been formed then heated at a temperature 100 200 0C. results an...
De-husking of foxtail millet is considered tedious work due to the small size millet. A study was performed determine de-husking parameters and also analyzing quality The soaked for 5h; then steamed 10 ± 1 min in a laboratory-scale parboiling unit drying at 50 0C 2 hours till moisture content reaches 12% (w.b). An increase length, breadth thickness observed from 2.66mm, 1.30mm 1.32mm 2.68mm, 1....
