[Purpose] This study aimed to identify correlations among pelvic positions and differences in lower extremity joint angles during walking in female university students. [Subjects] Thirty female university students were enrolled and their pelvic positions and differences in lower extremity joint angles were measured. [Methods] Pelvic position, pelvic torsion, and pelvic rotation were assessed us...

welding produces residual stresses and distortion, having detrimental effect on structure integrity and service performance of the welded pipe joints. this paper investigates residual stresses and distortion during gas metal arc welding (gmaw) of pipes of schedule 40 and 60, nominal diameter 100mm and 200mm and thickness 8mm and 10mm with ansi flanges of class 300#. welding parameters including...

A spherical parallel manipulator (also called an orientational parallel manipulator or rotational parallel manipulator) refers to a threedegree-of-freedom (3-DoF) parallel manipulator in which the moving platform undergoes a 3-DoF spherical motion or rotates about a fixed point. In this paper, we propose a new method for the type synthesis of non-overconstrained (isostatic) spherical parallel m...

This paper describes a method for a computerized analysis of diarthroid joints. The software implements reliable functions to study the shapes of the articulating surfaces through 2D arbitrary sections and geometrical fitting of lines/conics to quantify ligament behaviour through the computation of elongation, strain and orientation during the recorded motion. The software also allows for the c...

In the present study, 2, 4-dichlorophenoxyacetic acid (2, 4-D) was assessed individually for its effectiveness to induce somatic embryogenesis in tea (Camellia sinenesis L.). Embryonic axes and cotyledons explants were dissected from the seeds. Explants were cultured on Murashige and Skoog (MS) medium containing 0, 1 and 5 mM 2, 4-D alone for embryonic axes and 0, 1 and 5 mM 2, 4-D along with 0...

Introduction/Objective. The essence of the treatment degenerative knee joint diseases is pain relief, restoring motion range and stability joints. Methods. In this study, 35 patients participated after having surgery joint. had a posterior-stabilized (PS) endoprosthesis in one joint, posterior cruciate ligament retaining (CR) other. Kinematic data was collected using 3D optical system for track...

background:chronic synovitis is one of the most important complications in haemophilic patients. rifampin is anantibiotic which its intra-articular injecion leads to destruction of the synovial membrane of haemophilic patientsmedically.materials and methods: between september 2003 and november 2005, we administered intra-articular rifampinin ١۶ haemophilic joints of ٨ haemophilic patients.resul...

Abstract We present a semi-analytical method for computing the reflection and transmission coefficients at joints connecting an arbitrary number of semi-infinite orthotropic plates based on line-junction approximation. use wave approach describe reflection, mode conversion between eigenmodes vibro-acoustic equations plates. A detailed derivation is presented here first time meeting junction wit...

Nowadays, 3D printers based on Cartesian kinematics are becoming extremely popular due to their reliability and inexpensiveness. In the early stages of printer design, once it is chosen use kinematics, always necessary select relative positions axes linear drives (prismatic joints), which would be optimal for particular specification. Within class mechanics, many designs possible. Using Euler–L...
