کتاب تبصره المومنین(نگارش در سال1080ق) تالیف محمد مومن حسینی تنکابنی، جوابیه و ردّیه ای بر سخنان ملامحمد طاهر قمی در کتاب تحفه الاخیار است. این تحقیق تصحیح انتقادی و نقد وبررسی این کتاب است که نسخه مجلس شورای اسلامی اساس قرارداده شده و با سه نسخه دیگر مقابله شده است. نویسنده کتاب یکی از پزشکان دربار شاه سلیمان صفوی(1077) است. وی در عصری زندگی می کند که تصوف وصوفیان اگرچه درحمایت نسبی حکومت هستند...
Introduction: Chromium (VI) is a known human carcinogenic agent which is used in numerous industrial processes such as electroplating, welding, textile, cement and steel fabrication. The aim of this study was to determine the effectiveness of natural zeolite on the fixed bed adsorption of Cr (VI) from air stream. . Material and Method: In this experimental study, chromium mists were generated...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
بیش از سه دهه است که پژوهشگران سعی می کنند قطعات الکترونیکی با اندازه کوچکتر و کارایی هرچه بیشتر تولید کنند. در 20 سال اخیر کوشش های زیادی برای درک خواص رسانش الکترونی پلیمرهای همیوغ-? بعمل آمده است. این سیستم های نیمه رسانا نقش مهمی در طراحی سیستم های مولکولی برای کاربردهای الکترونیکی دارند. سیم های مولکولی واحدهای ساختاری بنیادی در طراحی قطعات الکترونیکی مولکولی هستند. یک سیم مولکولی شامل یک ...
In S. pombe, processes required for the maintenance of genetic integrity have been defined through the analysis of radiationsensitive mutants and the subsequent identification of genes involved in a range of different DNA damage responses, for example, nucleotide excision repair, recombination repair and DNA integrity checkpoints (Carr et al., 1994; Caspari and Carr, 1999; Murray et al., 1992; ...
The purpose of this study is finding the sensitivity of central bank independence measurements on its impact on inflation in Iran. To this aim different measurements of the central bank independence were calculated using the indices of Grilli et al. (1991), Cukierman et al. (1992), Mathew (2006) and Dumiter (2009) for the period 1961-2012 . Although results of correlation between CBI index and ...
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
abstract recent studies suggest that prelistening activities play an important role in the development of listening comprehension (e.g. long 1990;chiang and dunkel 1992; schmidt-rinehart 1994; jensen and hansen 1995; robinson et al., 1995; buck, 1995; foster and skehan,1996; teng 1996; robinson, 2001; chang and read 2006). in line with previous studies and to shed light on a new aspect of sche...
this study was carried out to obtain quantitative relationships between zn in equilibrium solution and that retained by 20 calcareous soils. soils were brought into equilibrium with varying solution concentrations of zn, and the amounts removed from solution were used to check the fit to six adsorption isotherms, namely, freundlich, langmuir, temkin, gunary, two surface langmuir and adjusted fr...
