testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
the upper level pressure patterns control the climate of the surface. the identification of these patterns in the regional scale is useful for the study of the surface climate elements and their forecasting. in order to understand the pressure centers controlling the climate of iran during the cold period of the year, the daily 500 hpa. geopotential height of the grid points of 2.5 degrees dist...
This article explores the relationship between vertical wind shear (VWS) and tropical cyclone (TC) genesis in Mozambique Channel (MC) for period 1979–2019. Additionally, SST, low-level relative vorticity, 700 hPa humidity upper-level divergence were also analyzed peak cyclogenesis months to explore their contributions. The analyses done using NCEP/NCAR Reanalysis-1 atmospheric fields, monthly O...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
introductionmany aspect strongly influence regional climate includes localized surface processes, large-scale patterns, especially mid and upper level tropospheric circulation and many factors control precipitation in the west of iran includes location of emigrate westerly winds systems, jet streams location, humidity flux and topography. upper tropospheric jet stream constitutes a significant ...
This study finds an increasing trend in the decay timescale (τ) of western North Pacific (WNP) tropical cyclone (TCs) making landfall on Asian continent from 1966–2018. Statistical analysis individual landfalling TCs shows that τ is significantly positively linked to soil wetness, 850-hPa relative vorticity and 200-hPa divergence, whereas it weakly correlated with 700–500-hPa humidity 850–200-h...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
the current study examined iranian undergraduate efl students’ willingness to communicate with regard to their vocabulary knowledge. in general, participants were somewhat willing to communicate in english. the total mean score of 730 university students’ perception of willing to communicate was 83.53 out of 135. results, regarding four parts of willingness to communicate, revealed that part...
The best test for the assessment of the hypothalamic-pituitary-adrenal (HPA) axis remains a matter of controversy. We compared the performance of the short synacthen test (SST, 250 microg) with the insulin stress test (IST) to assess the reliability of the former as a first line test. Patients with pituitary disease underwent both the SST and the IST. The results in patients who had both tests ...
