the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
The Diestel-Leader graph DL(q, r) is the horocyclic product of the homogeneous trees with respective degrees q+1 and r+1. When q = r, it is the Cayley graph of the lamplighter group (wreath product) Zq≀Z with respect to a natural generating set. For the “Simple random walk” (SRW) operator on the latter group, Grigorchuk and Żuk and Dicks and Schick have determined the spectrum and the (on-diago...
هدف از انجام این تحقیق ارزیابی اثر تکرارهای مکرر hcg بر روی ویژگیهای جسم زرد و فولیکولهای موجود بر سطح تخمدان و غلظت پروژسترون میش های سنجابی سوپراووله شده با ecg می باشد. تعداد 40 راس میش سنجابی بوسیله اسفنج آغشته به پروژسترون به مدت 12 روز جهت همزمان سازی فحلی مورد درمان قرار گرفتند . سوپراوولاسیون در این دامها بوسیله ecg، 2روز قبل از خروج اسفنج القاء شد. در روز خروج اسفنج (روز صفر) میش ها بص...
In this paper, we explore the spectral measures of Laplacian on Schreier graphs for several self-similar groups (the Grigorchuk, Lamplighter, and Hanoi groups) from dynamical algebro-geometric viewpoints. For these graphs, classical Schur renormalization transformations act appropriate parameters as rational maps in two variables. We show that spectra question can be interpreted asymptotic dist...
Suppose that G is a finite, connected graph and X is a lazy random walk on G. The lamplighter chain X associated with X is the random walk on the wreath product G = Z2 oG, the graph whose vertices consist of pairs (f, x) where f is a labeling of the vertices of G by elements of Z2 and x is a vertex in G. There is an edge between (f, x) and (g, y) in G if and only if x is adjacent to y in G and ...
in this research,the authors conducted a study comparing two groups of male and female english language learners studying in a elt institute,in terms of their performance on their achievement test including listening comprehension,vocabulary,grammar,and reading comprehension and found no significant difference between the group except in listening comprehension part of the test in which the f...
abstract the present study tried to investigate the effect of visual aids (films) on the development of the speech act of disagreement among iranian efl intermediate learners. to this end, the researcher selected 40 homogeneous intermediate learners based on their scores on oxford placement test. .the subjects then divided into control group and experimental group. both classes were tested by ...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
