Second language  learners often develop grammatical competence in the absence of concomitant pragmatic competence (Kasper & Roever, 2005) and the exact nature of the relationship between the two competences is still indistinct and in need of inquiries ( Bardovi-Harlig, 1999; Khatib & Ahmadisafa, 2011). This study is a partial attempt to address the lacuna and aims to see if any relationship ca...

abstractthis study examined the effect of two types of feedback, post-text as a written feedback and recast as an oral one on written grammatical accuracy of iranian intermediate efl learners. to this end, 45 intermediate students who were studying at ideal language institute in sari were selected based on their performance on the nelson proficiency test, and then divided into three groups (two...

We theoretically demonstrated that by the impregnation of Li-decorated IRMOF-10 with Li-coated C(60), the hydrogen storage capacity is improved to be 6.3 wt% and 42 g L(-1) at 100 bar and 243 K. Both the gravimetric and volumetric hydrogen uptakes reach the 2015 DOE target at near ambient conditions.

This report presents the synthesis of a tetraphenyladamantane-based microporous polycyanurate network with a BET surface area of 843 m(2) g(-1) and a pore size of 7.8 Å. It uptakes 98.0 wt% benzene (298 K, P/P0 = 0.9), 1.49 wt% H2 (77 K/1 bar) and 12.8 wt% CO2 (273 K/1 bar) with CO2/N2 selectivity of up to 112.

The present study, following Vygotskyan Sociocultural theory in education, and inspired by Rogoff’s conceptualization (1995, 2003) of development, aimed at conceptual development of  in-service EFL teachers. To this end, two Iranian EFL teachers with pseudonyms (Tara and Sara) were selected as participants of the study. The participating teachers were first taught the sociocultural c...

The purpose of the present study is to analyse abstracts related to Applied Linguistics, and more precisely the discourse functions of grammatical subjects and verbs. The corpus consisted of 50 PhD thesis abstracts written on the subject of Applied Linguistics. All of the abstracts were written from 2010 to 2014. The theses from which the abstracts were extracted are available in the ProQuest d...

In the present study, we have combined several atomic-scale computational techniques [static lattice optimization, density functional theory (DFT), canonical Monte Carlo (MC), and Gibbs ensemble MC (GEMC)] with experiment in order to describe adsorption of water potassium-exchanged X-type faujasite. Indeed, by applying DFT calculations, evidenced a strongly heterogeneous adsorbent surface class...

• Mechanical properties of concrete injected by epoxy were assessed experimentally. Epoxy-repaired was modeled combining FEM and cohesive elements. Repaired uniaxial compression three-point bending tests simulated. HMWM can penetrate cracks width 0.01 mm above gravity. steel-reinforced beams have a load capacity 30–40 Epoxy is widely used to fill that are less than millimeter in protect the ste...
