now-a-days graphic design plays a major role in influencing culture, society, business, and customers, in such a way that one could look upon every individual as a potential customer. graphic designers seek to identify customers needs and find an intelligent solution for them. correct identification and understanding of those needs is the first step towards achieving ones goals. marketing knowh...
Thermal behaviour of zeolites is an important property regarding their application in different fields. This property mainly is related to the presence of water molecules in their crystalline structures. It is known that zeolites give up water molecules upon heat ing, a phenomena which affects remaining water molecules and other clements in the framework. This effect mainly depends on the...
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
Zeolites are nanoporous crystalline alumino-silicates with a rich variety of interesting properties and industrial applications. With over 140 zeolite framework topologies synthetically available—each with its own range of compositions—zeolites offer size-, shapeand electrostaticallyselective adsorption, diffusion and reaction up to remarkably high temperatures. Zeolites are widely used as petr...
در این تحقیق، زنبورهای پارازیتویید شته ها (hymenoptera: braconidae: aphidiinae) در استان کرمانشاه مورد بررسی قرار گرفته و اطلاعات جدیدی در مورد فون زنبورهای aphidiinae کرمانشاه (در غرب ایران) ارائه شده است. نمونه برداری، در طول سال های 1388-1390 انجام گرفت و طی آن نمونه های متعدد گیاهان حاوی شته های سالم و پارازیته شده از مناطق مختلف استان جمع آوری شدند. شناسایی گونه ها بر اساس خصوصیات مرفولوژی...
the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
current article describes application of zeolites in fluid catalytic cracking (fcc). the use of several zeolitic additives for the production light olefins and reduction of pollutants is described. application of zeolites as fluid catalytic cracking (fcc) catalysts and additives due to the presence of active acid sites in the zeolite framework increase the formation of desired cracking product...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
