Complete Descriptions of Intermediate Operator Algebras by Intermediate Extensions of Dynamical Systems

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...

Dynamical Systems and Operator Algebras

We study the algebraic consequences of the traditional descriptions of dynamics based on differential equations. We thus show how C* -dynamical systems consisting of an action of a locally compact group on a C*-algebra provide a common framework for studying the time evolution and symmetry groups of systems in classical and quantum physics. AMS subject classifications. 46L55, 20C35, 81Pl0. One ...

the effect of subtitling on vocabulary learning of iranian intermediate efl learners

this study was an attempt to investigate the effect of subtitling on vocabulary learning among iranian intermediate students. to find the homogeneity of the groups, tofel test was administered to student in kish mehr institute in garmsar. after analyzing the data, 60 participants (female students) who scored within the range of one standard deviation above and below the mean, were selected as h...

acquisition of english determinative descriptions by persian efl learners

abstract since heubners (1985) pioneering study, there have been many studies on (mis) use/ non-use of articles by l2 learners from article-less and article languages. the present study investigated how persian l2 learners of english produce and interpret english definite descriptions and demonstrative descriptions. it was assumed that definite and demonstrative descriptions share the same cen...
