conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

This paper examines the decisive roles of strain and addiction in post-acceptance behavior of social networking sites’ users. Therefore, we focus in a first step on the formation of discontinuous usage intentions by theorizing strain, addiction, and satisfaction as direct influencing factor that causes and/or inhibits them. In a second step, the influence of these variables on the intention-beh...

the mesolimbic dopamine (da) system contains both d1-like and d2-like receptors, has been connected to control of locomotor behavior. an apparent role for d1 and d2 receptors throughout the mesolimbic system in the alteration of locomotor behavior has been demonstrated in pharmacological studies. the nucleus accumbens (nac) is comprised of a core and a shell subregion, which is a component of t...

Hadi Meidani,

A plasticity-fracture constitutive model is presented for prediction of the behavior of confined plain concrete. A three-parameter yield surface is used to define the elastic limit. Volumetric plastic strain is defined as hardening parameter, which together with a nonlinear plastic potential forms a non-associated flow rule. The use of non-associated flow rule improves the prediction of the dil...

The mechanical behavior of Zr41.25Ti13.75Cu12.5Ni10Be22.5 LM-1 has been extensively characterized under quasistatic loading conditions; however, its mechanical behavior under dynamic loading conditions is currently not well understood. A Split–Hopkinson pressure bar SHPB and a single-stage gas gun are employed to characterize the mechanical behavior of LM-1 in the strain-rate regime of 102–105 ...

The effects of carbon nanotubes on the mechanical behavior of elastomeric materials is investigated. The large deformation uniaxial tension and uniaxial compression stress-strain behaviors of a representative elastomer are first presented. This elastomer is then reinforced with multi-wall carbon nanotubes (MWNTs) and the influence of weight fraction of MWNTs on the large deformation behavior of...

Background: The Rapid Office Strain Assessment (ROSA) is one of the emerging posture assessment methods for the office workers. Limited studies have examined the validity of this method for the reliable assessment of the ergonomics risk factors among the office workers. The aim of this study was to investigating the relationship between the ROSA with anthropometric dimensions, knowledge and beh...

In this paper, the nonlinear behavior of R.C frames strengthened by shear walls and steel bracings is investigated. The use of steel bracing and R.C shear wall for strengthening of existing R.C structures usually leads to very complicated system and the study of the behavior of this kind of structures especially their connections, steel bracing area, and frame - shear walls and bracing interact...

During consolidation process of saturated cohesive soil the soil stiffness increases. Increase of the effective stress due to dissipation of excess pore pressure causes additional stiffness of soil mass. This phenomenon has a very important effect on the behavior of saturated cohesive soils during dynamic loading. In the current investigation the changes in maximum shear modulus. Gmax and dampi...
