This study was conducted to investigate the effect of meaning-focused versus form-focused input-oriented and output-oriented task-based instruction on elementary level Iranian EFL Learners’ vocabulary comprehension and recall. For this purpose, a sample of 120 male students from a private school in Tehran was selected through convenience sampling and based on availability. The participants were...

This paper presents the prediction of piezo-resistive behavior under quasi-static uniaxial compression loads using Percolation Excluded Volume (PEV) approach. The PEV approach is supplemented by Finite Element (FE) simulations to calculate displacements Carbon Nano-Tubes (CNTs) embedded in a polymer matrix. number contacts between CNTs determined minimum distance threshold (tunnelling distance)...

Pathogenic enterococci are becoming resistant to currently available antibiotics, including vancomycin, the drug of last resort for Gram-positive infections. Enterococci pose a significant public health threat, not least because of the risk of transferring vancomycin resistance to the ubiquitous Staphylococcus aureus. Vancomycin resistance is manifested by cell wall peptidoglycan precursors wit...

Phenol formaldehyde (PF) resins are widely used as wood adhesives in the industrial production of exterior-grade plywood panels, oriented strand board panels and particleboards due to their superior performance including high bonding strength, heat resistance, excellent water resistance and chemical stability1. However, phenol, one raw material for the synthesis of PF resins, is a petroleum-bas...

2014 By using a full electromagnetic-wave theory, an analysis is made of the ELF/VLF radiation resistance of a finite electric dipole, oriented at arbitrary angle in a cold, uniform magnetoplasma. The general integral expression for the radiation resistance R is derived, and from that, various approximate closed forms of R are obtained for the entire VLF/ELF range. Numerical plots of R are give...

this study aims at empirically furthering awareness of the organization of interaction in efl classes. informed by the methodological framework of conversation analysis, it draws upon a corpus of 52 three-hour naturally-occurring classroom interaction to identify classroom interactional contexts based on the structuring of the pedagogic goals in turn-taking sequences. conversation analytic proc...
