in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
the following null hypothesis was proposed: there is no significant difference between the efl students listening comprehension development receiving pictorial cues and those receiving no cuse. to test the null hypothesis, 52 male and femal freshmen students of medicine studing at iran university of medical scinces were randomly selected from a total population of 72 students. to ensure that th...
The pharmacokinetics of cefsulodin were characterized in 19 patients with different degrees of renal function after a single 500-mg, 30-min intravenous infusion. Six subjects had a creatinine clearance (Clcr) of greater than 100 ml min-1 (group I), eight had a Clcr of between 12 and 42 ml min-1 (group II), and five had a Clcr of less than 10 ml min-1 (group III). Nine plasma and four urine samp...
In 1907 ( l ) , Tyzzer clearly emphasized the probable rBle of heredity in the origin of tumors in mice. The advances made since that time, both in the genetic investigation of the spontaneous tumor and in the study of the transplantable tumor rest largely upon his interest and work. In his 1907 paper, Tyzzer wrote: “Are the races of mice which are susceptible to the inoculable tumors more liab...
As the primary route for elimination of clinafloxacin is renal clearance (CL(R)) of unchanged drug, studies were conducted to determine the pharmacokinetic profile of clinafloxacin following administration to young and elderly subjects, subjects with various degrees of renal function, and subjects requiring dialysis. These were open-label studies in which subjects received single oral clinaflox...
the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
