plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
In this work, total excitation cross section of atomic hydrogen in the collision of bare ion was calculated employing a three body Faddeev formalism. In the present calculation, initially the first order electronic amplitude was calculated using the interaction potential which led to inelastic form factor. Secondly, the first order nuclear amplitude was calculated and added to the first order ...
در این تحقیق، کاتالیزور نانو ذره ی n-پروپیل سولفونیت ساپورت شده بر روی سطح ?-fe2o3 (nps-?-fe2o3) برای اولین بار سنتز شده و از آن به عنوان یک کاتالیزور ناهمگن اسیدی جدید و قابل بازیافت جهت سنتز مشتقات ایندولی از قبیل 2-ایندولیل-1-نیترو آلکان ها و بیس ایندولیل متان ها استفاده شد. راندمان بالا، work up ساده، عدم استفاده از حلال های سمی، سهولت بازیافت و قابلیت استفاده مجدد از کاتالیزور و عدم تشکیل ...
Avian metapneumovirus (aMPV) represents one of the most prevalent diseases of poultry mainly in combination with other pathogens, and it is increasing among chickens. In the present study, the detection and characterization of an aMPV subtype B strain circulating in broiler flocks based on fusion (F) gene. In phylogenetic analysis, the isolates are located in B subtype cl...
This work observes that S-semigroups are essentially the representations of near-semirings to proceed to establish categorical representation of near-semirings. Further, this work addresses some approximations to find a suitable category in which a given near-semiring is primitive.
Background: Improper body positions such as kneeling, bending and twisting during saffron harvest, cause skeletal disorders. Low levels awareness about the true position of the body during work, is one of the problems of saffron workers. The purpose of this study, was training the correct body position in saffron pickers during work. Methods: This is a semi experimental study. Ssubjects were 3...
In this paper, the bi-criteria machine scheduling problems (BMSP) are solved, where discussed problem is represented by sum of completion and late work times simultaneously. order to solve suggested BMSP, some metaheurisitc methods which produce good results. The local search simulated annulling bees algorithm. results new compared with complete enumeration method, considered an exact then heur...
