the effects of including incoherent (bound-electron) and coherent (rayleigh) scattering in exposure buildup factor calculations for point isotropic gamma ray sources, penetrating a two-layer water-lead shield have been investigated in the gamma ray energy (e?) range of 40 kev to 3 mev. incoherent scattering decreases the values of these factors in both layers up to e? ~ 200 kev and the effect i...
Content and Language Integrated Learning (CLIL) has recently been the focus of numerous studies in language education since it aims to overcome the pitfalls of form-focused and meaning-focused instruction by systematically integrating content and language. This meta-analysis aims to synthesize the findings of 22 primary studies that tested the effect of CLIL on language skills and components. G...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
Up to now, the standardised motion sickness index has been mainly developed for shipping and only takes into account the vertical motion experienced by passengers. This index did not correlate with motion sickness incidence during two field tests realised in tilting trains conducted during 1998 and 2000. Therefore, a railway motion sickness index is required to predict the lack of comfort likel...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
هدف این مطالعه تعیین کردن این مساله است که آیا فراگیران فارسی زبان قادر به تطبیق پارامتری ضمیر موصولی that در جملات ساده و پیچیده ی انگلیسی در سایه اصل دستور جهانی هستند یا خیر. به علاوه نقش جنسیت در رابطه با آزمون تشخیص درستی یا نادرستی جملات دستوری مورد بررسی قرار گرفت. داده ها از 54 دانشجوی فراگیر زبان انگلیسی در دانشگاه فردوسی مشهد گردآوری شد. شرکت کنندگان در آزمون شامل 28 زن (51.85 درصد)و ...
بهینه سازی فرآیندها یکی از مهم ترین از فعالیت ها در صنعت محسوب می شود. هر زغال سنگ دارای عوامل ویژگی شناختی منحصربفرد است که در رفتار قابلیت شستشو تأثیرگذار هستند. همچنین یکی از دلایل پایین بودن کارآیی کارخانه های زغالشویی عدم شناخت کافی از خوراک است. در این تحقیق سعی شده است تا با انجام آزمایش های مختلف، طرح بهینه اختلاط مارک های مختلف زغالی معدن نرگسچال مشخص شود و برای اختلاط انجام گرفته سطوح...
