Abstract Introduction: In this study the role of PGE2 as an important inflammatory mediator in Indomethacine and Theophylline effects on joint diameter and vascular response of chronically inflamed rat knee joint to saphenous nerve stimulation was investigated. Methods: Inflammation was induced by intraarticular injection of 0.2 ml Freund,s Complete Adjuvant (FCA) and 3, 7, 14, 21 days post i...

periodic evaluation and monitoring the health and economic outcome of joint replacement surgery is a common and popular process under the territory of joint registries in many countries. in this article we introduce the methodology used for the foundation of the national iranian joint registry (ijr) with a joint collaboration of the social security organization (sso) and academic research depar...

the kinematics and dynamics of two industrial cooperating robots are presented in this paper. the noc (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. the joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. to this end, minimizing the cr...

This study considers the use of the joint location techniques for sets of Virginia earthquakes recorded by different station distributions. These input data sets consist of microearthquakes (mb < 3) recorded by local networks (post-1978) and larger, felt events (m~ _-< 4.6) that occurred in the same areas prior to network installation (pre-1978). Very different epicentral geometries (both linea...

in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...

background : joint proprioception plays an important role in limb movement and awareness of position sense. diabetes has a lot of complications such as lossof sensoryfunction, which canleadtoimpaired balance, thus the aim of this study to evaluated joint proprioception and balance in diabetic patients. methods: twenty type ii diabetic patients and20healthy controls participated in this case-con...

Based upon a framework of time-frequency analysis, a path towards systematic and comprehensive implementation of condition based maintenance (CBM), or maintenance only upon evidence of need, is outlined for both electrical and mechanical systems. Specifically, metrics are proposed for helicopter drivetrain systems and electrical cable. Using principles of time-frequency analysis, metrics for he...
