sawdust of the most inexpensive and abundant most engrossing read and the ability to absorb heavy metals from water and wastewater types. on the other hand increased metal hexavalent chromium (cr6 +) in drinking water cause toxicity, and complications from it can be. so the purpose of this research, effects of the dosage absorbent sawduste, equilibrium time, the efficiency of absorption and cal...
objective(s):blactx-mand blaper are two genes that encode class a extended-spectrum β-lactamases (esbls) and can be responsible for therapeutic problems. this study was carried out to evaluate the molecular properties of these genes in clinical isolates of enterobacteriaceae by polymerase chain reaction (pcr), restriction digestion and sequencing. materials and methods: during six months, start...
background and purpose:the tasks of faculty members and their weights particularly in integrated system of iran are not well defined. methods:to address this issue, in a comprehensive project, we explored all rules, regulations and officialdocuments in national level, collected the opinion of experts around the country using in-depthinterview and defined the weights of main tasks in a group dis...
در ابتدا به طور مختصر ارتباط بین مسائل تغییراتی و معادلات دیفرانسیل را بیان می کنیم. همان طور که می دانیم هر معادله دیفرانسیل را می توان به صورت egin{equation} label{yek} a(u)= 0 end{equation} نوشت، که در آن $ a(u) $ یک عملگر دیفرانسیل معمولی یا جزئی خطی یا غیرخطی و $ u $ مجهول می باشد. برای حل این معادلات و به خصوص معادلات دیفرانسیل جزیی غیرخطی راه حل مشخصی وجود ندارد.حساب تغییر...
the nmr spectra of azo dyes, 5-arylazobarbituric (5a-g), 5-arylazo-1,3-dimethylbarbituric(6a-g) and 5-arylazothiobarbituric acids (7a-g) were studied in dmso-d6 in differentconcentrations. an intramolecular hydrogen bond was observed and indicating that thehydrazone forms is mostly predominant. the peak of the hydrazone proton was severelybroadened and its chemical shift appeared at down field ...
a total of 160 day-old male broiler chickens (ross 308) were divided in a completely randomized design experiment, and assigned to 8 treatments and 4 replicates in their experimental units (cages). treatments included: t1: basal diet with no additional methionine, t2: basal diet plus 0.06, t3: basal diet plus 0.11, t4: basal diet plus 0.17 % of dl-methionine, t5: basal diet plus 0.06, t6: basal...
a new carbazole- containing polymer has been synthesized for further photophysical studies. efficient synthesis of the substituted methyl methacrylate has been accomplished via microwave assisted synthesis of 1 - chloro - 4-carboxy -5,6, 7, 8- tetrahydrocarbazole followed by further steps, such as reduction of the 4-substituted methyl carboxylate, dechlorination of the ring and at last, the rea...
antimicrobial resistance is one of the most severe threats to human health. the first report of plasmid-mediated colistin resistance in escherichia coli from animals, food, and humans was in 2015 from china. the current increasing trend of resistance is extremely troubling because polymyxins are the last-resort antibiotics for treating infections with carbapenem-resistant enterobacteriaceae.
introduction: cardiovascular disease is the major cause of morbidity and mortality in developing and developed countries. rapid diagnosis of the thrombosis can be an essential step in management of the stroke. methods: in this work a recently developed radiolabeled streptokinase (stp) tracer was evaluated in an animal thrombotic model using spect imaging and biodistribution studies. locally lab...
the present experiment was conducted to determine metabolizable energy of pomegranate peel and pulp by adult cockerels. the pomegranate peel and pulp samples were gathered from three industries. this study had two experiments. each experiment was done in a completely randomized design with 4 treatments and 4 replicate (1 cockerel each). the cockerels fed conventional addition method (cam). the ...
