in this study, the bacterial diversity in the activated sludge system of a full-scale municipalwastewater treatment plant in dubai was monitored over a period of one year using ribosomal rna (rrna)targeted oligonucleotide probes for a defined phylogenetic group of bacteria by the fluorescence in situhybridization (fish) technique. the largest fraction of the bacterial community in the sludge sa...
the cancerous spread of slum has been a rampant problem in urban areas worldwide. the acute shortage of housing facilities compels the poor to live in slums. proper rehabilitation is considered as a very essential remedial measure to provide better living environment to slum peoples. this study is an essential attempt to gauge the effectiveness of a rehabilitation program, which studies the cha...
background: the excellent biocompatibility, biodegradability and biological properties of the hydrogels, fabricated using natural polymers, especially polysaccharides, are very advantageous for biomedical applications. gum tragacanth (gt) is a heterogeneous highly branched anionic polysaccharide, which has been used extensively in food and pharmaceutical industries. despite, its desirable prop...
obtaining samples that represent original fluid of reservoirs optimizes reservoirs management. the optimized management increases recovery. also, selecting and performing proper improved oil recovery (ior) or enhance oil recovery (eor) programs depend on collecting representative samples. achieving accurate compositions of original in-situ fluid prevents overdesigning surface facilities. repres...
we have studied the medicinal plants of ghasemloo and then surveyed the usagepercentage of different parts from each specimen for the medicinal or diet consumptions atthree sites from the adjacent villages of ghasemloo valley, villages of west and eastazerbaijan including 17 questioners. during two years, the medicinal plants that have beencollected and provided as herbarium specimens were reco...
poly(styrene-co-butyl acrylate)/clay nanocomposites were synthesized via in situ atom transfer radical polymerization using activators generated by electron transfer in the presence of a montmorillonite ion-exchanged with mixed surfactants of dodecyl trimethyl ammonium bromide and vinyl trimethyl ammonium chloride. the living nature of polymerization is confrmed by occurrence of narrow molecula...
the focus of this study was to determine if early detection of mutant p53 accumulation may be an early indicator of tumor aggressiveness and transformation to invasive breast cancer. for this purpose, the p53 content of 100 human breast biopsies classified as ductal carcinoma (dcis), was evaluated by immunohistochemical method. all specimens were microscopically classified into histologic types...
influenza c virus possesses specific neuraminate-o-acetylesterase as a receptor-destroying function. this enzymatic activity of the viral glycoprotein hef (hemagglutinin, esterase activity and fusion factor) can be visualized in situ by the use of distinct color substrates. hereby the localization, as well as the quantity of synthesized hef protein is detectable. we further developed the estera...
Plant and microbial use of nitrogen (N) can be simultaneously mutualistic and competitive, particularly in ecosystems dominated by mycorrhizal fungi. Our goal was to quantify plant uptake of organic and inorganic N across a broad latitudinal gradient of forest ecosystems that varied with respect to overstory taxon, edaphic characteristics, and dominant mycorrhizal association. Using C and N, we...
هدف از انجام این تحقیق بررسی روند تغییرات در ترکیبات شیمیایی و تجزیه پذیری علوفه گیاه یونجه طی سه مرحله رشد قبل از گلدهی، اواسط گلدهی و گلدهی کامل می باشد. به این منظور از دو رأس گوسفند فیستوله گذاری شده برای آزمایشات in situ و in vitro استفاده گردید. برای انجام آنالیز آماری داده ها در قالب طرح کاملا تصادفی از نرم افزار sas و جهت تحلیل و بررسی داده های تجزیه پذیری از برنامه کامپیوتری naway استف...
