t akotsubo cardiomyopathy (tcm), also known as stress-induced cardiomyopathy, is a clinical syndrome of transient left ventricular (lv) apical wall motion abnormality with relative preservation of the basal heart segments in the absence of any significant atherosclerosis. recurrence of this condition is rare. we report a postmenopausal woman, who experienced two episodes of tcm within 4 months ...

in this study, the analysis of transient thermoelastic response of a functionally graded (fg) non-axisymmetric viscoelastic cylinder is presented. the material properties are assumed to be time- dependent and radially and circumferentially non-homogeneous. the finite element (fe) formulations of the thermoelastic problem are obtained using the virtual work method and all the coupling terms are ...

this study was to investigate the most important stressors and causes of job dissatisfaction in employees if an industrial setting. 230 full-time workers and employees were selelcted through random sampling. a questionnaire that included five categories of stressors (permanent and transient factors related to the type of job and the work environme nt, accident producing factors, relationship pr...

We investigate, using simultaneous rheology and confocal microscopy, the time-dependent stress response and transient single-particle dynamics following a step change in shear rate in binary colloidal glasses with large dynamical asymmetry and different mixing ratios. The transition from solid-like response to flow is characterised by a stress overshoot, whose magnitude is linked to transient s...

National Bureau of Standards Gaithersburg, MD 20899 Studies of transient wave propagation in plates were carried out to establish a basis for the impact-echo technique as a nondestructive test for flaw detection in concrete. The surface displacements caused by stress waves generated by point impact on a plate were calculated using both the Green's function solution and the finite element method...

S U M M A R Y We use idealized subduction megathrust models to examine aseismic, frictional fault creep throughout the interseismic period. We consider rate-dependent and rateand state-dependent friction. When there is significant post-seismic creep surrounding locations of coseismic slip, the creep rates surrounding an asperity may be lower than the plate convergence rate late in the seismic c...

Sex differences and pretrauma functioning have been understudied in examinations of posttraumatic stress symptoms (PSS) and health. This study examined relationships between sexual harassment and assault in the military (MST), PSS, and perceived physical health when accounting for pre-MST PSS, pre-MST health, and current depression. Relationships were examined separately in 226 female and 91 ma...

introduction: transient hyperglycemia is a condition that happens during acute physiologic stress in children.  the aim of this study is to determine if there is any relation between stress hyperglycemia and diabetes mellitus and metabolic syndrome in pediatric patients.   materials and methods:  the study was performed on children hospitalized in amirkola pediatric hospital, north of iran, bet...

In this paper, transient thermomechanical stress intensity factors for functionally graded cylinders with complete internal circumferential cracks are obtained using the weight function method. The finite difference method is used to calculate the time dependent temperature distribution and thermal stresses along the cylinder thickness. Furthermore, finite element analysis is performed to deter...

a number of innocent rashes occurs in neonates. they are usually transient and self limited and thus require no therapy but early recognition is important to distinguish these lesions from more serious disorders. in this study, our purpose was to determine the frequency of birthmarks in iranian neonates. the presence of various types of birthmarks was determined in 503 iranian neonates under 72...
