A new arbitrarily high order method for the solution of the model Boltzmann equation for micro-channel flows in the transitional regime is presented. The Bhattnagar-Gross-Krook approximation of the Boltzmann collision integral is implemented, with Shakhov’s modification, and the resulting system of equations solved by a discrete ordinate method. The method approximates velocity space using a tr...
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...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
methodology non-native participants in this study were sixty ba students majoring in english literature and teaching english as a foreign language at khayyam university of mashhad. they were senior students, between 21 to 24 years old, who had studied english for at least three and a half years and had passed several courses including grammar, reading, conversation, and writing. this was assum...
the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Possible mechanisms of dihydroxy bile salt-induced K+ secretion by the mammalian colon were evaluated by studying the effects of taurochenodeoxycholate (TCDC) on 86Rb+ transport across the isolated, short-circuited rabbit distal colon. Simultaneous measurements of 86Rb+ and 42K+ unidirectional fluxes were highly correlated [r = 0.964 for serosal (s) to mucosal (m) and 0.765 for m to s], indicat...
Introduction The diffusion restrictions present in biological tissue result in deviations from the Gaussian propagator shape, which can be quantified using the apparent kurtosis Kapp [1]. Kapp is defined by eq. 1, where <φ > is the expectation value of the n-th power of the spin phase, and it appears in the expansion of the logarithmic signal in powers of b (eq. 2). [ ] 2); ( ... 6 ) 0 ( ) ( ln...
melamine trisulfonic acid (mtsa) is utilized as a highly efficient catalyst for the solvent-free condensation reaction of 2-naphthol (2 eq.) with arylaldehydes (1 eq.) under conventional thermal as well as microwave conditions to give the d
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
