the behavior of earth dams has particular complexities against dynamic forces and its assessment requiresdetailed and scientific analysis. the farrokhi earth dam is a heterogeneous type with vertical clay core, built 150 km away from birjand and 41 km away from qaen on the farrokhi river. there are concernsregarding the stability of this dam in the event of a future severe earthquake especially...

purpose: to compare the preoperative and postoperative measurement of intraocular pressure (iop) using goldman applanation tonometry (gat), the air puff and pascal dynamic contour tonometers (pdct) in eyes undergoing myopic and myopic astigmatic photorefractive keratectomy (prk). methods: in a descriptional -analytic and prospective study, a complete examination was performed at the slit lamp, ...

Abstract With the rapid development of renewable energy, a large number energy stations are connected to power system, which leads decrease in inertia system and an increase safety risks suffered. Thus, online static security assessment (SSA) is increasingly necessary. However, because uncertainty it not feasible check all possible scenarios SSA. To reduce calculations achieve SSA short time, n...

Honeycomb cores are widely used in the aerospace and automotive fields as a part of protective structures. Unfortunately, standard prismatic honeycomb offer limited amount energy absorption under lateral loads suffer from degradation their impact-deadening properties when dimensional scale is increased. In this work, multiscale study on quasi-static load carried out 3D-printed core samples cons...

The purpose of this study was to provide a thorough description of lumbar surface integrated electromyography (EMG) in pain-free normals during a standardized assessment protocol of static isometric and unresisted dynamic tasks. It has been proposed that in pain-free normals, symmetrical tasks that bend the trunk forward or extend the trunk backward produce symmetrical paraspinal EMG activity, ...
