the role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولOn Representation of Integers by Quadratic Forms.
The operation of finding the limit of an infinite series has been one of the most fruitful operations of all mathematics. While this is not a group operation the theory of continuous transformation groups inaugurated by S. Lie has thrown much new light on this operation. The assumption that only two elements are combined at a time applies to continuous groups as well as to those which are disco...
متن کاملOn the Representation of Integers by Quadratic Forms
Let n > 4, and let Q ∈ Z[X1, . . . , Xn] be a non-singular quadratic form. When Q is indefinite we provide new upper bounds for the least non-trivial integral solution to the equation Q = 0, and when Q is positive definite we provide improved upper bounds for the greatest positive integer k for which the equation Q = k is insoluble in integers, despite being soluble modulo every prime power.

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Representation of Integers by Near Quadratic Sequences
Following a statement of the well-known Erdős-Turán conjecture, Erdős mentioned the following even stronger conjecture: if the n-th term an of a sequence A of positive integers is bounded by αn2, for some positive real constant α, then the number of representations of n as a sum of two terms from A is an unbounded function of n. Here we show that if an differs from αn 2 (or from a quadratic pol...
