The study aimed was to measure left ventricular (LV) strain using speckle tracking echocardiography (STE) for assessment of LV function. Eighty-two subjects (mean age 57±9 years) with suspected chest pain underwent two-dimensional (2D)-echocardiography before coronary angiography. Conventional echocardiographic parameters were used for the assessment of LV function. Longitudinal strain and its ...

In this paper, a displacement-based, variationally consistent, two variable refined theory for shear deformable beams is presented. The beam is assumed to be of linearly elastic, homogeneous, isotropic material and has a uniform rectangular cross-section. In this theory, the beam axial displacement and beam transverse displacement consist of bending components and shearing components. The assum...

The pathogenicity and transmission of influenza A viruses are likely determined in part by replication efficiency in human cells, which is the net effect of complex virus-host interactions. H5N1 avian, H1N1 seasonal, and H1N1 2009 pandemic influenza virus strains were compared by infecting human differentiated bronchial epithelial cells in air-liquid interface cultures at relatively low virus p...

background nursing teachers have difficulties fulfilling multiple roles expectations and balancing the various dimensions of their roles that may lead to role strain. in order to lack of culturally and academically proper scale in iran to measure role strain in nursing teachers, localizing a foreign scale in this field is necessary. objectives the objective of this study was psychometric evalua...

the relations of fibrolite-biotite are discussed by presenting data from the ardara aureole, nw ireland. biotite-fibrolite intergrowths are developed in all three aureole zones including: the outer kyanite-bearing andalusite zone, the middle kyanite-free andalusite zone and the inner prismatic sillimanite zone. a strain-assisted mechanism is proposed for the fibrolitisation of biotite in the ar...

Safety analysis has been done for the torsion of a functionally graded thick-walled  circular cylinder under internal and external pressure subjected to thermal loading. In order to determine stresses the concept of Seth’s transition theory based on generalized principal strain measure has been used. This theory simplifies the set of mechanical equations by mentioning the order of the measure of...
