the purpose of this study was to investigate how english language teachers in mashhad who teach students in the pre-university cycle perceived the impact of the efltee on their teaching. the target population was nearly all pre-university english language teachers in seven districts of mashhad in the scholastic year 2008/2009. a survey questionnaire which consisted of (36) likert type items, wa...
the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
Seasonal solar thermal-energy storage systems used for space heating applications is a promising technology to reduce greenhouse gas emissions. A novel system with seasonal and cascade based on zeolite water proposed in this study. The system’s efficiency improved through the release of energy. energy density deep coupling daily cross-seasonal storage. mathematical model system-performance anal...
This paper studied the performance of a compressor-assisted thermochemical sorption energy storage (CATSES) system with solar photovoltaic-thermal collector (PV/T) to support domestic space and hot water heating. The heat from PV/T drives endothermic desorption, whilst electricity powers compressor assist low-temperature desorption. main aim this study was demonstrate that integrated can flexib...
exercise training has been shown to decrease chronic low- grade systemic inflammation in high- fat diet induced obesity. however, the mechanisms mediating its beneficial effects are not fully understood. therefore, the aim of this study was to investigate the effects of a 12- week endurance training on il-6, il-10 and nesfatin -1 in obese male rats. sixteen male wistar rats (2 months old) were ...
In this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of Sarcheshmeh copper complex was studied. The comminution circuit of this plant includes one SAG mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. The goal of this work was to calcu...
