the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
در محیط محاسبات فراگیر، تمام وسیله هایی که قصد برقراری ارتباط با یکدیگر را دارند با رویدادها سر و کار دارند. به همین دلیل، کشف سرویس ها و مدیریت رویدادها در این محیط از حساسیت و پیچیدگی محسوسی برخوردار است. با توجه به اهمیت موضوع، هدف این رساله ارائه ی شیوه ایست که با استفاده از پایگاه داده ی فعال و به کارگیری قوانین eca (event, condition, action)، پیچیدگی رویدادهای بین وسیله ها را کاهش داده ...
BACKGROUND Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently been linked to atrial fibrillation. We therefore systematically studied the molecular composition of left and right atrial tissue in adult murin...
تعیین پارامترهای سینتیکی و ضرایب استوکیومتری واکنش هیدروکراکینگ و بررسی سینتیکی واکنشهای گوگردزدائی و ازت زدائی در حضور هیدروژن که عنوان پروژه را تشکیل می دهد ابزاری لازم جهت مشابه سازی سیستم راکتوری هیدروکراکینگ برای طراحی صنعتی، کنترل راکتور و نهایتا دستیابی به دانش فنی (maximum isomerezation) isomax برشهای سنگین نفتی و تبدیل آنها به فرآورده های سبک و میان تقطیری (دیزل و کروسین) می باشد. درای...
introduction: educational justice is a process by which all those involved in education are pondering and seeking to establish it in their regulatory environments. this study aimed to investigate effective factors in an ideal educational justice and the current condition of educational justice from the students’ viewpoint and ultimately increase the awareness and understanding of authorities an...
laan in (ph.d thesis, tartu. 1999) introduced the principal weak form of condition $(p)$ as condition $(pwp)$ and gave some characterization of monoids by this condition of their acts. in this paper first we introduce condition (g-pwp), a generalization of condition $(pwp)$ of acts over monoids and then will give a characterization of monoids when all right acts satisfy this condition. we also ...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
A connection graph represents resolvability in a set of clauses explicitly. The corresponding connection graph proof procedure has the deeciency that the graphs may grow, becoming impractical to handle. We present a novel proof procedure for condition graphs, which is a reenement of connection graphs. Our idea is to control the growth of the graph by recognizing tests in clauses and translating...
