synthesis and characterization of potentially biological active cyclometallated organoplatinum(ii) complexes
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولInfluence of Stream channel morphology and in-stream habitats on fish community in Golestan province Streams
Four streams with different sizes were selected for studying the effects of environmental factors on fish assemblages using indirect (Detrended Correspondence Analysis, DCA) and direct (Redundancy Analysis, RDA) gradient analysis in Golestan province. DCA of presence-absence and relative abundance data showed well gradient and linear model of species variability. In the within-site RDA, environ...
متن کاملInvestigating the Effect of Palangan fish Farms on Water Quality of Sirvan River Using Physicochemical and Biological Indicators
The effect of Palangan fish farms on water quality of Sirvan River was investigated using physicochemical and biological indicators from January 2015 to June 2015. Five stations were determined including 1) before the fish farm 2) after the fish farm effluent 3) sub-branch 4) 100 meter after fish farm effluent and 5) 1000 meters after fish farm effluent. EC showed significant differences in dif...
متن کاملUV effects on invertebrate and diatom assemblages of Greece.
The effects of solar radiation (PAR, UVA, UVB) on the productivity and structure of diatom and invertebrate assemblages were assessed during primary succession on artificial substrate near a rocky shore of the Saronikos Gulf, Greece. Three light treatments were performed (PAR, PAR+UVA, and PAR+UVA+UVB) at 0.5, 1.0 and 1.5 m of depth. Pennate diatoms were the major component of the developing pe...
