Introduction and purpose:The efficiency of the processes involved in maintaining balance and gait, especially the nervous system, decreases due to changes in various systems of the body such as the sensory system of visual, vestibular and proprioceptive systems. The current study was conducted to analyze the effect of the combination and Pilates exercise programs on static and dynamic balance i...
The purpose of this study was to determine the relationship between changes of some of the cardiorespiratory factors during submaximal activity with slow component of Vo2 after static and dynamic stretching in 16 active women from physical education college ( Mean ± SD : age, 23.87± 1.62 yr ; weight, 57.20 ± 7.84 kg ; height, 163.46 ± 6.23 cm; body fat % ,23.96 ± 2.70 and Vo2max, 42.15 ± 3.4...
Two types of rodingitization (static and dynamic) are observed in the rodingites of the ophiolite north of Nain. Two stages have been occurred in the formation of static rodingites. At the initial stage, epidote, prehnite and hydrogrossular have crystallized respectively at the expense of plagioclase, with the increase of Calcium content rodingite forming fluid. In the advanced stage, xonotlite...
In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static...
In the present article a numerical procedure is developed for dynamic analysis of single and double autofrettage of thick–walled FG cylinders under transient loading. The governing differential equations are discretized and presented in explicit Lagrangian formalism. The explicit transient solution of discrete equations are obtained on the meshed region and results for stress and strain distrib...
The Taguchi method is a useful technique to improve the performance of products or processes at a lower cost and in less time. This procedure can be categorized in the static and dynamic quality characteristics. The optimization of multiple responses has received increasing attention over the last few years in many manufacturing organizations. Several approaches dealing with multiple static q...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
Objectives: the present research aimed to study the effects of whole body vibration, mental practice and combined vibration and mental practice on static and dynamic balance of elderly men. Methods & Materials: this was a semi-experimental research. The participants included 42 healthy, elderly men aged (60-80 yrs) from Mashhad who was randomly categorized into 4 groups: vibration (n=12), me...
In mode II interlaminar fracture toughness tests of composite laminates, the evaluated based on linear elastic mechanics deviates from true due to material nonlinearity matrix. this study, an elastoplastic finite-element analysis was performed a new quasi-static test, i.e., doubly end-notched tension (DENT) investigate difference between perceived energy release rate and J-integral. The effect ...
Objectives: Balance functions play a significant role in routine life of the elderly, especially in reducing the risk of their falling. The aim of this research was to investigate static and dynamic balance of healthy elderly men during different hours of the day. Methods & Materials: For this purpose, 10 old men with the mean (SD) age of 69.45(3.23) years participated voluntarily ...
