the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
abstract the current study sets out 1) to investigate the strategic needs of iranian efl learners in reading literary and non-literary texts; 2) to shed some light on the differences between reading literary and non-literary texts; and 3) to specify the differences in the interaction of participants with texts while reading two literary subgenres ( i.e., short story and literary essays). to ...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
the present research was an attempt to see how quranic lexical collocations were translated into english by two professional translators namely, abdullah yusuf(2005), and muhammad s. shakir(2012). the study attempted qualitatively to shed light on how translators dealt with quranic lexical collocations when transferring them to the target language based on the newmark(1988) model , and quantit...
This paper addresses the stress field of reinforced concrete (RC) beam–column joints retrofitted with haunches. Design such solution currently assumes internal forces evaluated by so called β-factor approach, which was originally conceived targeting enhancement steel moment-resisting frames. Extension to RC is subsequent as it emerges from literature survey. The analytical model first criticall...
The high level of shear stress present in reinforced concrete deep beams has been the subject interest for a considerable number studies due to uncertainties involved. Several structural codes and standards around world have recommended using strut-and-tie method (STM) design such elements. STM is proven efficient accurate, however, successful application relies decisively on skills designer co...
Shear strength of precast concrete ribbed slabs reinforced with electro-welded lattice girders variable height is experimentally verified. Technical justification given for the use high latticework in reinforcement lightweight double-tee and 30 cm thickness. It was established that contribution to shear always higher than expected values according Spanish standards. Furthermore, as low exhibite...
The influence of the in-stream pylon and strut on the performance of scramjet combustor was experimentally and numerically investigated. The experiments were conducted with a direct-connect supersonic model combustor equipped with multiple cavities. The entrance parameter of combustor corresponds to scramjet flight Mach number 4.0 with a total temperature of 947 K. The research results show tha...
During septorhinoplasty, septal cartilage is frequently resected for various purposes but the L-strut is preserved. Numerous materials are inserted into the nasal dorsum during dorsal augmenation rhinoplasty without considering nasal structural safety. This study used a finite element method (FEM) to redefine the septal L-strut, to prevent collapse as pressure moved from the rhinion to the supr...
