among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...

teachers’ beliefs greatly influence their performance in the classroom, their choice of instructional strategies, their way of controlling the class, their dealing with the students, and their general goals and objectives. one of these beliefs is teachers’ sense of efficacy which is viewed as an important construct and has shown to be positively correlated with students’ achievement (ross, 1992...

the purpose of this quantitative study was to investigate the relation between efl teachers’ self-efficacy beliefs and their success. moreover, the study was an analysis of the teacher age, gender and years of teaching experience, to examine the manner in which these factors relate to teacher self-efficacy as defined by bandura (1997) and teaching effectiveness as evaluated by their own student...

the present paper offers a postcolonial reading of two of the best novels by v. s. naipaul – half a life and the mimic men – in five chapters. the focus of this research is on different notions of postcolonial criticism and their application on the two novels as discussed from homi bhabha’s and frantz fanons points of view. having introduced the life and literary career of v. s. naipaul in th...

the article focuses on archive's significance, the importance of its location, as well as its atmospheric fluctuations. the hazardous factors to a repository and its records might come from neighboring factories, heavy traffic, carbon dioxide, fire, burst water and sewage pipes, flood, direct exposure to sunlight, dust, chemical materials, tiny atmospheric particles, andbiological factors....

in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...

1.1 introduction “i see translation as the attempt to produce a text so transparent that it does not seem to be translated. a good translation is like a pane of glass. you only notice that it’s there when there are little imperfections- scratches, bubbles. ideally, there shouldn’t be any. it should never call attention to itself.” “norman shapiro” (venuti, 1995:1) edward fitzgerald is the br...

بندپایان در حدود 75درصد انواع جانوران از جمله کنه های ایکسودیده ، بزرگترین شاخه جانوری می باشند (یخچالی و حاجی حسن زاده زرزای, 1383). خانواده کنه های سخت در زیر راسته متااستیگماتا و راسته کنه سانان (آکارینا) از شاخه بندپایان قرار دارند (wall and shearer, 2001). تاکنون 650 گونه و در حدود 13 جنس در 5 زیرخانواده از آنها گزارش گردیده است (wall and shearer, 1997; wall and shearer, 2001 ). به طوری که...

one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...

burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
