The effect of mechanical activation on structural changes and kinetics of carbothermic reduction of hematite with graphite was studied in this research. Hematite powder mixture with graphite (with stoichiometry ratio C/O=1) was milled for the time periods of zero to 50 hours, and the structural changes were studied using X ray diffraction (XRD). The effect of mechanical activation on the kineti...
بررسی ریزمغذی ها در مواد گیاهی و تأثیر آن بر بیماری های سخت همچون سرطان مورد توجه بسیاری از متخصصان در حوزه های مختلف علوم از جمله علوم پایه، علوم پزشکی و کشاورزی می باشد. یکی از این عناصر سلنیوم می باشد که به طور مشخص بر روی تمامی سرطان ها تاثیرگذار می باشد. این ماده ضد اکساینده قوی است بنابراین از واکنش شیمیایی زیان آوری که در یاخته های بدن اتفاق می افتد، جلوگیری می کند. یاخته های حمایت شده ق...
Background: Platelet storage is complicated by deleterious changes that cause progressive structural and functional damages, so-called platelet storage lesion (PSL). PSL is commonly manifested by augmented platelet activation which is also associated with the increased levels of reactive oxygen species (ROS). Whether ROS generation increases during the storage of platelet concentrates and wheth...
