electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. the results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. in addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobarbitu...
فرض کنید iایده آلی از حلقه ی جابجایی و نوتری r باشد به طوری که ara(i)=t ? 2. هدف از این پایان نامه این است که نشان دهیم دنباله ی منظم –iصافی y1،...، yt از ایده آل i وجود دارد به طوری که rad(i)=rad(y1,…,yt) و به ازای هر 1? i? t، cd((y1,…,yi),r)=i که یک نتیجه ی مهم از کرونکر1 [17] است. بعلاوه، در این پایان نامه نشان می دهیم که برای هر –rمدول باتولید متناهی مانند m و به ازای هر i ? r که r ? 1، اگر...
background: this study was undertaken to evaluate the viability, infectivity and immunity of toxoplasma gondii tachyzoites exposed to 2-(naphthalene-2-ylthio)-1h-indole. methods : tachyzoites of rh strain were incubated in various concentrations of 2- (naphthalene-2-ylthio)-1h-indole (25-800μm) for 1.5 hours. then, they were stained by pi and analyzed by fluorescence-activated cell sorting (f...
a series of novel 2-aminopyrimidine and 2-substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against adp and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. none of the compounds showed satisfactory activity against the aggregation induced by adp. however, satisfac...
the role of cu, zn and co in human physiology is well documented. isatin and glycine have inhibitory effects on central nervous system. to capitalize on these features metal complexes of isatin-3-glycine were prepared and evaluated for anticonvulsant activity. the cu (ii) complex was found to be most active among the compounds. the compounds were screened against staphylococcus aureus, escheric...

در حلقه نوتری و جابجاییr ، ایده آل i را به طور نرمال آزاد از تاب گوییم هرگاه به ازای هر t?1، ass(r/it) =ass(r/i). در این پایان نامه یک روش بازگشتی برای مطالعه ایده آلهای تک جمله ای آزاد از مربع به طور نرمال آزاد از تاب، ارائه می دهیم و با استفاده از آن نشان می دهیم که اگر i یک ایده آل تک جمله ای آزاد از مربع باشد که به طور مینیمال آزاد از تاب نیست آنگاه کوچکترین توان آن، که دارای ایده آل اول مح...
a new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. the synthesised compounds have been screened in vitro for their antimicrobial acti...
