the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
deposite the different criticisms on contrastive analysis it has been proved that the results of it(when processed)can be usuful in a tefl environment,specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims. the consonants,vowels,stress and intonation of the twolanguages are described by the same model-ta...
In this paper, we present new variants of global bi-conjugate gradient (Gl-BiCG) and global bi-conjugate residual (Gl-BiCR) methods for solving nonsymmetric linear systems with multiple right-hand sides. These methods are based on global oblique projections of the initial residual onto a matrix Krylov subspace. It is shown that these new algorithms converge faster and more smoothly than the Gl-...
This paper is motivated by an old and central problem in measurable dynamics: given two dynamical systems, determine whether or not they are measurably conjugate, i.e., isomorphic. Let us set some notation. A dynamical system (or system for short) is a triple (G,X, μ), where (X,μ) is a probability space and G is a group acting by measure-preserving transformations on (X,μ). We will also call th...
Introduction. In the present paper a new invariant quadratic differential form Û is geometrically defined for a general pair of surfaces S> S' whose corresponding points x, x' determine the metric normal to S a t x. The ratio of the form Q to the first fundamental form ds of 5, in which Î2 and ds are defined for a common arc element of S at x, is found to be independent of the direction of the ...
abstract this research is about a longitudinal case study of english morpheme acquisition by a persian speaking child l2 learner of english (2 .9-3).the goal of this research has been discovery of the child ‘s ability in acquiring of english morphemes in a persian context while only one person (the child’ s father)has been talking to her.this child has also been exposed to english languag...
in this paper, we study the extremal ranks and inertias of the hermitian matrix expression $$ f(x,y)=c_{4}-b_{4}y-(b_{4}y)^{*}-a_{4}xa_{4}^{*},$$ where $c_{4}$ is hermitian, $*$ denotes the conjugate transpose, $x$ and $y$ satisfy the following consistent system of matrix equations $a_{3}y=c_{3}, a_{1}x=c_{1},xb_{1}=d_{1},a_{2}xa_{2}^{*}=c_{2},x=x^{*}.$ as consequences, we g...

abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...
We study Livsic's problem of nding satisfying X = where is a given function and X is a given Anosov vector eld. We show that, if is a continuous solution and X; are analytic, then is analytic. We use the previous result to show that if two low-dimensional Anosov systems are topologically conjugate and the Lyapunov exponents at corresponding periodic points agree, the conjugacy is analytic. Anal...
