Objective: The effective variables in maintaining balance come from sensory information that is obtained from sensory-visual, vestibular and visual systems, and is affected by coordination, range of motion and muscle strength. The purpose of this study was to investigate the relationship between neuromuscular mechanisms and the static and dynamic balance of soccer players. Methods: In an analy...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
چکیده: در این تحقیق تأثیر ملاس که یکی از محصولات جانبی صنایع قند می باشد به عنوان یک افزودنی مقاومت خشک جدید در بهبود پالایش پذیری و ویژگی های فیزیکی و مکانیکی مقوای کنگره ای کهنه (occ) مورد بررسی قرار گرفته شد. بدین منظور پنج سطح ملاس( 0،5، 10، 15 و 18%) و سه سطح درجه روانی(420،400و320 میلی لیتر)به عنوان فاکتورهای متغیر در نظر گرفته شد و برای هر تیمار کاغذهای دست ساز با مساحت 2cm200 و وزن پای...
introduction: the shoulder is one of the most vulnerable joints for handball players. frequent throwing movements can change its muscular strength balance and range of motion. however, the balance of strength and range of motion are important factors in injury prevention. the purpose of this study was to compare the internal-to-external ratios of strength rotation and rom rotation in the domin...
Abstract: The purpose of this study is to produce scarf joint through explosive welding process (EXW). The scarf weld is a process in which the final bond interface is oblique. With applying the explosive welding technique, this joint can create a metallic bond between similar or dissimilar metals. In this study, chamfered end of aluminum and copper plates were joined explosively and named scar...
The purpose of this study was to evaluate the effect of eight weeks strength and plyometric trainings on knee joint position sense. In this study, 45 male students (21.7±2.17years, weight 69.7±7.89 kg, and height 177.2±5.83cm) volunteered and selected as subjects to participate in this semi-empirical study. Subjects divided in three groups include strength (n=15), plyometric (n=15) and cont...
Purpose: Most studies have examined the effect of stretching and strength exercises on the glenohumeral joint (shoulder joint), on the other hand, due to the importance of the relationship between core stability and pectoral girdle, especially in archery athletes, the aim of this study was to investigate the effect of six weeks of core stability exercises on the glenohumeral joint internal rota...
Background: The glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. The most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. Imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing ...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
خواص فیزیکی و مکانیکی چوب مورد مطالعه قرار گرفته است . برای اینکار چوب درخت چنار انتخاب شده است . آزمایشات انجام شده هم بصورت استاتیک و هم بصورت دینامیک بوده است . نمونه هائی با رطوبت و دانسیته های مختلف آزمایش شده اند. همه موارد آزمایشات در دمای آزمایشگاه انجام شده است . خواص مکانیکی چون ضریب ارتجاعی (modulus of elasticity) حد تناسب (proportional limit) حد کشش (tensile strength) تاب خرد شدگی (...
