کار حاضر از چهار بخش تشکیل شده است. در بخش اول دو دستگاه اسپکتروفتومتر uv/vis و جذب اتمی شعله ای جهت اندازه گیری بکار گرفته شد. از لیگاند دی تیزون برای پیش تغلیظ و استخراج یونهای کادمیم(??) استفاده شد. غلظت اولیه محلول نمونه ppm1 بود که توسط بافر آمونیاکی ph آن در 10 تثبیت شده بود. در شرایط بهینه حد تشخیص روش ?g/l 37/0 (بر اساس ?3)، محدوده خطی ?g/l 50-5 و انحراف استاندارد نسبی 1/1% بدست آمد. د...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
In this work, the effects of medium composition and fermentation parameters on the simultaneous production of mycelial biomass and exopolymer by medicinal mushroom Hericium erinaceus CZ-2 were investigated in shake flask cultures using one-factor-at-a-time method and orthogonal array design. Results showed that the most suitable carbon, nitrogen, mineral sources, and cofactors for the mycelial ...
two iranian strains of brachionus rotifers were cultured under different food and salinity regimes. the rotiferswere fed with five algal types (freshwater and marine chlorella vulgaris, nannochloropsis occulata, isochrysisgalbana and scenedesmus obliquus) at three different salinities (5, 15 and 25 g/l) and their reproductive and growth parameters were assessed. the maximum number of ovigerous ...
Background and purpose: 2, 4 dinitrophenol is the most important nitrophenol compound that is widely used in paints, adhesives, wood preservatives, solvents, pesticides, and explosive materials. Because of the high toxicity and non-biodegradability of 2, 4 DNP, must be prevented from entering the water body. The aim of this study was to evaluate the performance of ordered mesoporous carbon CMK-...
s June 9 turned into June 10, crowds kept surging toward the Hachiko area west of Shibuya station. Shibuya has long been a boisterous focal point for Tokyo youth, but this was something else. Japan had just won their Group H match against Russia, and Tokyo was celebrating as if the World Cup was theirs. The honking horns and chants drowned out the megaphones of the massively outnumbered police....
let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...

Reactions of 0.5 eq. of the dinuclear complexes [(g-arene)Ru(l-Cl)Cl]2 (arene = g-C6H6, g-p-PrC6H4Me) and [(Cp*)M(l-Cl)Cl]2 (M = Rh, Ir; Cp* = g-C5Me5) with 4,6-disubstituted pyrazolyl-pyrimidine ligands (L) viz. 4,6-bis(pyrazolyl)pyrimidine (L1), 4,6-bis(3-methyl-pyrazolyl)pyrimidine (L2), 4,6-bis(3,5dimethyl-pyrazolyl)pyrimidine (L3) lead to the formation of the cationic mononuclear complexes...
IMPORTANCE Hyperkalemia is a common electrolyte abnormality that may be difficult to manage because of a lack of effective therapies. Sodium zirconium cyclosilicate is a nonabsorbed cation exchanger that selectively binds potassium in the intestine. OBJECTIVE To evaluate the efficacy and safety of zirconium cyclosilicate for 28 days in patients with hyperkalemia. DESIGN, SETTING, AND PARTIC...
