دو نوع کمپلکس باز شیف سه دندانه ی (onn)، با ساختار عمومی [nil1(pr3)] که در آن r = bu , ph و l1 = (e)-1-[(2-amino-5-nitrophenyl)imino-methyl]naphthalene-2-olate سنتز و به وسیله ی تکنیک هایft-ir ،uv-vis، 1h-nmr، آنالیز عنصری و پرتو ایکس شناسایی و تعیین ساختار شدند. مطالعه ی پرتو ایکس ساختار مسطح مربعی و چهارکوردینه را در حالت جامد برای کمپلکس نشان می دهد. به منظور بررسی تاتومری و بهینه سازی ساختا...
native population of raspberry fruits (rubus spp) were treated with methyl jasmonate (mj) fumigation and were assayed for the antioxidant capacity, total anthocyanins and postharvest quality after 7 days storage at 4?c. the result of experiment revealed that berries treated with methyl jasmonate (mj) showed higher antioxidant capacity and total anthocyanins compared to the controled ones (non...
a bacterial strain (strain ps) was isolated from the textile effluents carrying serilene black bnfs® (c.i. disp. blk. mix) disperse dye. the isolate was able to decolorize the dye without the need for any exogenous carbon source. full sequencing of its 16s rrna indicated that bacillus sp strain ps is related to bacillus cereus groups. silica- gel-thin layer chromatography of serilene black dye...

the present study was carried out to investigate the potential of carboxylate group functionalized multi-walled carbon nanotubes (mwcnt−cooh) adsorbent for the removal of methyl orange (mo) textile dye from aqueous solutions. the effects of ph, shaking time and temperature on adsorption capacity were studied; the contact time to obtain equilibrium at 298 ˚k was fixed at 25 min. the effect of te...
objective(s) the central nucleus of the amygdala (cea) is a forebrain structure which is important in regulation of ingestive behavior and there is direct and circumstantial evidence to indicate that some circuits involved with feeding behavior include glutamatergic elements. the present study examined whether administration of nma (n-methyl-dl-aspartic acid) or mk801 into the cea altered water...
methyl tert-butyl ether (mtbe), a gasoline octane enhancer, was introduced as a substitute for lead tetraethyl over 30 years ago. widespread use of mtbe in gasoline, has introduced mtbe into the environment compartments, mostly into the under ground and surface water and water as a second most frequently detected contaminant. in this study, we have isolated pure cultures from bacterial consorti...
