In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...
the concept of imagery is to make an image of successful movement skill or a relaxing image in mind with no body training and external experience. the aim of the present study was to compare the effect of traditional and pettlep mental imagery methods on static and dynamic balance. the statistical population consisted of all female university of tehran students who had general physical educatio...
Fusionless devices are currently designed to treat spinal deformities such as scoliosis by the application of a controlled mechanical loading. Growth modulation by dynamic compression was shown to preserve soft tissues. The objective of this in vivo study was to characterize the effect of static vs. dynamic loading on the bone formed during growth modulation. Controlled compression was applied ...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
The response speed of Web pages is one of the necessities of information technology. In recent years, renowned companies such as Google and computer scientists focused on speeding up the web. Achievements such as Google Pagespeed, Nginx and varnish are the result of these researches. In Customer to Customer(C2C) business systems, such as chat systems, and in Business to Customer(B2C) systems, s...
conclusions a short-term wbv exercise improves isotonic strength of the leg muscle and dynamic balance, while creatine supplementation with and without wbv training increases isometric strength of the leg muscle and mobility in elderly women. background a decline in neuromuscular function can cause a decrease in physical fitness in elderly women. objective the present study aimed at investigati...
Abstract Young’s modulus of New Red Sandstone was investigated experimentally to gain insight into its nonlinear nature. A large experimental programme carried out by applying a controllable quasi-static and dynamic uniaxial loading 286 dry sandstone samples four different sizes. The static tests, similar those aiming at determining the compressive strength, were conducted using state-of-the-ar...
The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...
