the issue of curriculum and syllabus evaluation and revision has been in center of attention right from when curriculum came into attention of educational institutions. thus everywhere in the world in educational institutions curricula and syllabi are evaluated and revised based on the goals, the needs, existing content, etc.. in iran any curriculum is designed in a committee of specialists and...
the present study aimed at exploring cognitions of iranian english teachers within the context of english for academic purposes (eap). to this end, the cognitions of two groups of eap teachers with respect to their pedagogical content knowledge (pck) and their sense of professional identity (pi) were probed. two language teachers and two content instructors who had at least five years of eap te...
چکیده «محکم و متشابه»، «نسخ» و «قرائات» از موضوعات مهم علوم قرآنی است. آیت الله معرفت در هر سه موضوع ضمن نقد دیدگاههای گذشته و رایج، به ارائه نظریاتی بدیع پرداخته اند. تعریف روشن از محکم و متشابه، تفاوت بین متشابه و مبهم، طبقه بندی تشابه به ذاتی و عرضی و ضابطه مند ساختن معانی تأویلی و باطنی، از جمله نوآوری های آیت الله معرفت در حوزه محکم و متشابه به شمار می رود. در موضوع نسخ، شاهد دو قرائت...
A novel numerical approach to analyze the mechanical behavior within composite materials including inelastic regime up final failure is presented. Therefore, a second-gradient theory combined with phase-field methods fracture. In particular, we assume that polymeric matrix material undergoes ductile fracture, whereas continuously embedded fibers undergo brittle fracture as it typical e.g. for r...
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
this study was an attempt to investigate and compare the effect of lexical inferencing and concept mapping on developing vocabulary retention of iranian language learners. sixty homogeneous students from different intact classes who were being taught as intermediate learners in sokhan english institute participated in this study. they were in different classes. a teacher made test as a pre-test...
The tensile properties of multiscale, hybrid, thermoplastic-based nanocomposites reinforced with nano-CaCO3 particles and micro–short glass fibers (SGF) were predicted by a two-step, three-dimensionalmodel using ANSYS finite element (FE) software. Cylindrical and cuboid representative volume elements were generated to obtain the effective behavior of the multiscale hybrid composites. In the fir...
Complex arrays with good aperiodic properties are characterised and it is shown how the joining of dimensions can generate sequences which retain the aperiodic properties of the parent array. For the case of 2× 2× . . .× 2 arrays we define two new notions of aperiodicity by exploiting a unitary matrix represention. In particular, we apply unitary rotations by members of a size-3 cyclic subgroup...
We have shown previously that asbestos and other mineral dusts, including glass fibers, induce cell transformation and chromosomal mutations in Syrian hamster embryo cells in culture. In the present study, we observed that both asbestos and glass fibers were phagocytized by these cells and accumulated in the perinuclear region of the cytoplasm. In order to understand the mechanism of fiber leng...
