iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...

The aim of this study was identifying different populations and determining the genetic characteristics of three different sub-adult stocks of Litopenaeus vannamei in hatchery of Iran Shrimp Research Center by microsatellites DNA markers in Bushehr province during from October to November 2019. Up to 50 individuals were sampled per stock, with equal contribution by sex. The tissue preserved in ...

Evaluation of genetic diversity is the key principal for plant breeding, providing an opportunity to discover novel characters and alleles for breeders. In the present study, 69 durum wheat genotypes were investigated for genetic diversity using several inter-simple sequence repeat (ISSR) markers. Sixteen ISSR primers amplified a total of 163 fragments, which out 160 fragments were polymorphic....

bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

The present study was performed to classify and study genetic diversity between Calotropis procera accessions from different regions of Kerman province (Iran) using ISSR markers. In total, DNA from 14 plant samples with nine ISSR primers was amplified by PCR and their banding pattern was obtained. The primers showed acceptable polymorphism (35.93) and minimum and maximum polymorphic information...
