Measurements of the spin dependence of large l, j = l ——, ', transfer reactions at medium energies provide a stringent test of three-body reaction models. We report measurements of the cross section (da/d Q), vector ( A~ ) and tensor ( A» ) analyzing powers, and outgoing proton polarization (p) angular distributions (8, =6.9'-82. 3') for the l= 3, j"=2 ground-state transition in Zn(d, p) Zn mea...

‏‎the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...

Microspatial analyses of the trace element composition of dental enamel are made possible using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Fine spatial resolution, multielement capabilities, and minimal sample destruction make this technique particularly well-suited for documenting the distribution of elements in sequentially calcifying layers of enamel. Because de...

The stellar electron capture on nuclei is an essential, semi-leptonic process that especially significant in the central environment of core-collapse supernovae and explosive nucleosynthesis. In this article, basis original (absolute) electron-capture cross-sections under laboratory conditions we computed our previous work for a set medium-weight nuclear isotopes, extend study evaluate folded e...

There is a lack of certified reference materials with an organic matrix for which metal isotope ratios have been certified. Here, we determined the iron, copper and zinc stable isotopic compositions six biological origin diverse matrices, i.e. BCR-380R (whole milk), BCR-383 (beans), ERM-CE464 (tuna fish), SRM-1577c (bovine liver), DORM-4 (fish protein) TORT-3 (lobster hepatopancreas) in three d...

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...

Volatile elements are key to understanding the accretion and differentiation processes that formed terrestrial planets. Relative solar photosphere or carbonaceous Ivuna-type (CI) chondrites, planets depleted in moderately volatile (MVEs), with Earth being more MVEs than Mars. Mass-dependent mass-independent stable isotope variations of MVEs, such as Zn, can be used determine origin depletion on...

the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
