Abstract The present study is an attempt to investigate the relationship between cohesive readability of expository texts and reading comprehension in EFL students with different proficiency levels. One hundred students formed the participant of this study. They were undergraduate students majoring in English at University of Isfahan. To collect the relevant data, participants were divide...

Cohesive frames are linguistic elements that precede the grammatical subject in the main clause. This study investigated the frequencies and communicative purposes of cohesive frame types in results and discussion section of research articles from 4 disciplines. To run this study, 40 results and discussion sections of research articles were selected from 4 disciplines, namely Applied Linguistic...

This paper presents a new micromechanical model for a collection of cohesive zone models embedded between each mesh of a finite element-type discretization. It aims to forth fully extend the previous linear results of [1] to the calibration of damageable cohesive parameters (cohesive peak stress, critical opening displacement, cohesive energy, etc). The main idea of the approach consists in rep...

1 The Effect of Cohesive-Law Parameters on Mixed-Mode Fracture R. B. Sills and M. D. Thouless Department of Mechanical Engineering Department of Materials Science & Engineering University of Michigan Ann Arbor, MI 48109-2125, USA Abstract Cohesive-zone models of fracture provide a framework that allows a smooth transition between a strength-based approach to fracture and an energy-based approac...

In this paper Cohesive Zone Model (CZM) concepts are applied in order to study mode I fracture in a pre-cracked bonded Double Cantilever Beam (DCB) specimen. A cohesive surface element is implemented in a Finite Element commercial code using intrinsic cohesive zone models: exponential, bilinear and trapezoidal traction-separation laws. The sensitivity of cohesive zone parameters in predicting t...

medication error (me) is the most common preventable cause of adverse drug events which negatively affects patient safety. inadequate, low-quality studies plus wide estimation variations in me from developing countries including iran, decreases the reliability of me evaluations. to clarify sources, underreporting reasons and preventive measures of mes, we reviewed iran current available literat...

In finite element analysis (FEA) models of cemented hip reconstructions, it is crucial to include the cement-bone interface mechanics. Recently, a micromechanical cohesive model was generated which reproduces the behavior of the cement-bone interface. The goal was to investigate whether this cohesive model was directly applicable on a macro level. From transverse sections of retrieved cemented ...

Finite element calculations of dynamic fracture based on embedding cohesive surfaces in a continuum indicate that the predictions are sensitive to the cohesive law used. Simulations were performed on a square block in plane strain with an initial edge crack loaded at a constant rate of strain. Cohesive laws that have an initial elastic response were observed to produce spontaneous branching at ...
