an investigation into oral interaction in language classes: a conversation analytic point of view the aim of this thesis is to analyze the interaction between language teachers and students in english language institutes. this work is done in the context of yasuj city. learning another language, which is in most cases english, involves many variables. one of these variables is the linguistic...
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
Molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. By this method we can calculate many chemical and biochemical properties of large scale biological systems. In this work all-atom molecular dynamics simulation of polyalanine (PA) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 M of guanidinium chlorid...
esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
Background and Objectives: Cholerae disease caused by toxigenic V. cholerae, is a major public health problem in developing countries including Iran. Epidemiological surveillance and comparative molecular analysis of isolates have demonstrated clonal diversity among epidemic strains and a continual emergence of new clones of toxigenic V.cholerae. Material and Methods: A total of 20 V.cho...
Synthesis of Some Benzofuran Derivatives Containing Pyrimidine Moiety as Potent Antimicrobial Agents
In this investigation, the synthesis of 2-substituted pyrimidines by the reaction of benzofuranchalcones (3a-d) with urea, thiourea and guanidine hydrochloride was reported. The structuresof title compounds (4a-d), (5a-d) and (6a-d) were established on the basis of analyticaland spectral data. The synthesized compounds were screened for antimicrobial activityand molecular docking studies. Some ...
background: geothermal waters could be suitable niches for thermophilic free living amoebae including naegleria and hartmannella . ardebil province, northwest iran is popular for having many hot springs for recreational and health purposes activity. the present research is the first molecular based investigation regarding the presence of naegleria and hartmannella in the hot springs of ardebil...
in this research work, genetic diversity of 21 wild persian shallot (allium hirtifolium boiss.) accessions from south, southwest, west and center of iran was evaluated using morphological traits as well as aflp markers. results showed that khansar accession had the highest leaf width (5.42 cm), mean leaf number per plant (5.41), bulb diameter (10.84 cm), bulb height (4.95 cm) and mean bulb weig...
yersinia enterocolitica is rapidly emerging worldwide as an enteric pathogen and has become a major cause of diarrhea even in developed countries. the aim of this study was to characterize and genetic diversity analysis among y. enterocolitica strains isolated from fish and chicken sources.from 44 strains, 55% (24 strains) found to be positive for y. enterocolitica by colony morphology, biochem...
background: stimulation of collateral artery growth (arteriogenesis) and/or capillary network growth (angiogenesis) would be beneficial to the patients with myocardial infarction. to understand the central role of vascular endothelial growth factor (vegf) in biological angiogenesis, we performed molecular analysis of the vegf gene in patients afflicted with acute myocardial infarction (ami). ...
