background and aim: total hip replacement (thr) is done comprehensively all over the world. despite the effects of braces on control of thr complications , few studies have been performed on this subject. the purpose of this study was to evaluate immediate effect of hip abduction brace on mobility and functional balance of patients with thr.    materials and methods: eight men and nine women wi...

Abstract—Nowadays, energy dissipation devices are commonly used in structures. High rate of energy absorption during earthquakes is the benefit of using such devices, which results in damage reduction of structural elements, specifically columns. The hysteretic damping capacity of energy dissipation devices is the key point that it may adversely make analysis and design process complicated. Thi...

background: considering the negative consequences of using physical restraints, we conducted this study to identify patients who are more frequently restrained in a psychiatric emergency ward as an initial step to limit the use of restraint to the minimum possible. methods: this was a retrospective case control study conducted in iran psychiatric hospital in tehran, iran. we reviewed the files ...

A case study of retrofitting a 20-story pre-Northridge steel moment-frame building is presented. Twelve retrofit 4 schemes are developed with varying degrees of intervention. Three retrofitting techniques are considered: up5 grading the brittle beam-to-column moment resisting connections, and implementing either conventional or 6 buckling-restrained brace elements within the existing moment-fra...

‎For any integer $kgeq 1$‎, ‎a set $S$ of vertices in a graph $G=(V,E)$ is a $k$-‎tuple total dominating set of $G$ if any vertex‎ ‎of $G$ is adjacent to at least $k$ vertices in $S$‎, ‎and any vertex‎ ‎of $V-S$ is adjacent to at least $k$ vertices in $V-S$‎. ‎The minimum number of vertices of such a set‎ ‎in $G$ we call the $k$-tuple total restrained domination number of $G$‎. ‎The maximum num...

A structural soundness monitoring system for building steel structures is effective a quick inspection just after large earthquakes. damage-controlled structure can be monitored effectively because damage strictly concentrated in energy-absorbed members, and that, this case, the physical quantity suitable displacements of those energy absorbed members. Buckling-restrained braces (also, BRB usin...

Background The Maastricht brace (M-brace) was developed to improve compliance and associated efficacy of brace treatment in adolescent idiopathic scoliosis (AIS). Initial pressure measurements in the M-brace revealed a higher corrective pressure as compared to the Boston brace, and a better patient reported quality of life, as measured with the SRS 22 and Brace questionnaire. We present the fir...
