the photocatalytic degradation of nonionic surfactant triton x-100 was studied by a batch process using znocommercial powders as the catalyst on irradiation with uv light and its behaviour comparatively with respect tozno nanoparticles with diameter size 20 nm. the effects of different conditions such as catalyst type, amount ofthe photocatalyst, ph of the system, initial concentration and elec...
political islam is the only active religion discourse in the world claiming to have program for religion and the muslim world and to achieve this goal it must gain political power. from its existence the dialogue has triggered different experiences in islamic countries. the most important victory of the islamic revolution in iran in 1979 and egypt's muslim brotherhood movement was to seize...
hie-124 is a new member of ultra-short acting hypnotics’ drug family. in this research, the synthesis ofanalogues of hie-124 drug in the heterocyclic thiazole ring replaced to thiadiazole, will be presented.thiadiazolodiazepines during a two-step reaction starting from the amino thiadiazole resultedfrom-various derivatives of benzoic acid and thiosemicarbazide were synthesized. in the first ste...
background: pinopodes are suggested as biological markers of uterine receptivity, but their molecular components are unknown. objective: co-expression of galectin-3 and ?v?3 integrin at human pinopodes has been examined in this study to propose a role for them during adhesion phase of embryo implantation. materials and methods: biopsies were obtained from early and mid luteal phase endometrium ...
in order to investigate the effects of municipal waste compost and benefit fungi of trichoderma species on seedling emergence parameters, growth and some micronutrients uptake of garden cress a pot experiment was carried out in factorial arrangement based on randomized complete block design with 3 replications. treatments consisted of three levels of municipal waste compost (15, 30, 45 mg ha-1 ...
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: one of the major steps for planning and making polices in iranian health and health service sector is to gain information on the condition of such services in each province. thus, the present study intended to determine the degree of development and ranking of provinces at this sector. it can identify the undev...
in this work, zncao2 (zinc oxide-calcium oxide) nanocomposite were synthesized at different temperatures (500-700°c) by sol-gel method based on polymeric network of polyvinyl alcohol (pva). the synthesized samples were characterized by sem/edax, ft-ir and xrd techniques. it was found that synthesized nanocomposites have 1.62, 2.05 and 13.91%wt of cao, respectively. the obtained results show tha...
nanocrystalline alumina powder has been synthesized using solution combustion method. the obtained nanocrystalline alumina powder was used as an efficient catalyst for the synthesis of imidazo[1,2-a]azine derivatives from one-pot three component reaction of benzaldehyde, 2-aminoazine and trimethylsilylcyanide under ultrasonic irradiation and refluxing condition. reusability of catalyst and shor...
introduction compartmental analysis allows the mathematical separation of tissues and organs to determine activity concentration in each point of interest. biodistribution studies on humans are costly and complicated, whereas such assessments can be easily performed on rodents. in this study, we aimed to develop a pharmacokinetic model of 153sm-maltolate complex as a novel therapeutic agent and...
degradation of o,o-dimethyl -o-4-nitrophenylphosphorothioate (methylparathion) by ozonation in aqueous solution was studied in a batch reactor under constant ozone dosage and variable ph conditions. the effectiveness of the process was estimated based on the degree of cod (chemical oxygen demand) reduction and conversion of methylparathion. it was observed that ozonation is more effective at a...
