bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...
The factor complexity function C w (n) of a finite or infinite word w counts the number of distinct factors of w of length n for each n ≥ 0. A finite word w of length |w| is said to be trapezoidal if the graph of its factor complexity C w (n) as a function of n (for 0 ≤ n ≤ |w|) is that of a regular trapezoid (or possibly an isosceles triangle); that is, C w (n) increases by 1 with each n on so...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
In this paper, we consider a class of connected oriented (with respect to Z/p) closed G-manifolds with a non-empty finite fixed point set, each of which is G-equivariantly formal, where G = Z/p and p is an odd prime. Using localization theorem and equivariant index, we give an explicit description of the mod p equivariant cohomology ring of such a G-manifold in terms of algebra. This makes ...
the author intend to by studying the historical causes of the appearance of the novation in the west and explanation of its legal nature from past to present of french law, proves on the one hand that the novation does not extracted from the french civil code and in the shiite jurisprudence with quite similar terms even before the enactment of iranian civil code, was considered by the shiite su...
background: intraoperative radiation therapy (iort) technique is used to treat a surgically exposed tumor or tumor bed in the treatment of locally advanced intraabdominal, retroperitoneal, pelvic, thoracic, breast and soft tissue tumors. one way to perform iort is to use an existing linac and modify the treatment head using an applicator system. in this study the objectives were to design, and ...
Let I be a non empty set, let X be a non-empty many sorted set indexed by I, and let i be an element of I. Observe that X(i) is non empty. In the sequel S denotes a non void non empty many sorted signature and V denotes a non-empty many sorted set indexed by the carrier of S. Let us consider S and let V be a many sorted set indexed by the carrier of S. The functor S -Terms(V ) yielding a subset...
the thesis has been arranged into five chapters and mainly concerned with the baer-invariant of groups which is the generalization of the schur-multiplier with respect to the variety of groups. chapter one is devoted to collect some notation and background information which are needed in the next chapters. its also contains some important statements which will be generalized in this thesis. cha...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
