the purpose of this study was to find the relationship between critical thinking and self-regulation with reading comprehension of iranian female elementary language learners. the present study is a correlational one having a descriptive design. two questionnaires, critical thinking questionnaire and self-regulation questionnaire which were valid and reliable questionnaires and four reading com...
The primary role of the vascular system is to carry blood and oxygen to tissue. This task is complicated by the vastly differing needs of tissues for oxygen according to their metabolism. Moreover, the metabolic activity in a given organ, and thereby its need of blood flow and oxygen, may dramatically change in time scales varying from seconds (during the onset of muscular exercise for example)...
It is known that use of the Web by academic researchers is discipline-dependent and highly variable. Moreover, the Web is increasingly central for sharing information, disseminating results and publicizing research projects and so it is important to find out as much as possible about how it is used, and who is using it successfully. In this pilot study we seek to identify the subjects that have...
A k_n Latin rectangle is a k_n matrix of entries from [1, 2, ..., n] such that no symbol occurs twice in any row or column. An intercalate is a 2_2 Latin subrectangle. Let N(R) be the number of intercalates in R, a randomly chosen k_n Latin rectangle. We obtain a number of results about the distribution of N(R) including its asymptotic expectation and a bound on the probability that N(R)=0. For...
ρf,` : Gal(k̄/k)→ Aut(Jf [`](k̄)) ' GL2g(F`) on the `-torsion points of Jf is as big as possible for almost all primes `, if the following two (sufficient) conditions hold: (1) the endomorphism ring of Jf is Z; (2) for some prime ideal p ⊂ Zk, the fiber over p of the Néron model of Cf is a smooth curve except for a single ordinary double point. These conditions can be translated concretely in ter...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...
