از این روی، 56 دانشجوی رشته ی مترجمی زبان انگلیسی دانشگاه کاشان در این تحقیق شرکت نموده و سه متن از نوع توضیحی نیستند و همچنین هیچ رابطه معناداری بین flow و پیشینه ی یادگیری فراگیران وچود ندارد. در بخش کیفی مطالعه، با 4 نفر از فراگیران که از میان جمعیت اماری فاز اول مطالعه انتخاب شده بودند مصاحبه گردید که اطلاعات به دست آمده در این قسمت، یافته های آماری را تأئید می کند. کلید واژگان: flow، نو...
We describe a method for comparing nuclear and organelle population differentiation (F(ST)) in seed plants to test the hypothesis that pollen and seed gene flow rates are equal. Wright's infinite island model is used, with arbitrary levels of self-fertilization and biparental organelle inheritance. The comparison can also be applied to gene flow in animals. Since effective population sizes are ...
Exposure or likelihood of occurrence of an identified hazard is a key factor used by regulators in determining the magnitude of risk. One example of exposure is the amount of gene flow between transgenic crops and their non-transgenic counterparts or their compatible wild relatives. Gene flow itself is not a hazard, but instead represents the exposure of the environment to transgenes and the po...
Pollen-mediated gene flow (PMGF) is the main mode of transgene flow in flowering plants. The study of pollen and gene flow of transgenic wheat can help to establish the corresponding strategy for preventing transgene escape and contamination between compatible genotypes in wheat. To investigate the pollen dispersal and gene flow frequency in various directions and distances around the pollen so...
Tomato yellow leaf curl virus (TYLCV) is a supreme pathogen in tropical and subtropical areas. During 2014-2015, a total of 393 tomato samples showing Tomato yellow leaf curl disease (TYLCD) symptoms were collected from six different provinces of Iraq. In serological assays, 55 out of 393 samples (14%) reacted positively with TYLCV-specific antibodies .The presence of TYLCV was verified in 21 (...
Background : Genetic manipulation is an effective strategy to protect cells against environmental damages and enhance their capabilities for therapeutic usage. In order to avoid unwanted side effects, such as cancers, the expression of genes should be temporary increased. The aim of this study was to clone and temporary increased expression of a cell protective gene, Metallothionein 1 (MT1) in ...
Introduction: Following the first description of multiple myeloma (MM), as the second most prevalent hematologic malignancy, multiple promising advances have paved the way to increase the long-lasting complete remission for patients. In the era of the novel therapeutic approaches, the cloning of the apoptosis-inducing genes into the genome of malignant cells has attracted tremendous attention. ...
The cave barb habitat is located in a Karst formation along the Sezar River. The springs on the walls of the Sezar River valley may provide a means for fish in surface waters to penetrate into the underground waters. These observations propose the probability for a migratory relationship between Garra gymnothorax in the Sezar River and the cave barbs (Garra typhlops and Garra lorestanensis). In...
