in this paper, we present an analytical method for solving a well-posed boundary value problem of mathematical physics governing the vibration characteristics of an internal flow propelled fluid-structure interaction where the pipeline segment is idealized as an elastic hollow beam conveying an incompressible fluid on a viscoelastic foundation. the effect of coriolis and damping forces on the o...

utilizing polymeric materials for damping mechanical waves is of great importance in various fields of applications such as military camouflage, prevention of structural vibrational energy transfer, and noise attenuation. this ability originates from segmental dynamics of chain-like polymer molecules. damping properties of styrene-butadiene rubbercontaining 10 wt% of monosize polystyrene partic...

Purpose: The present study aimed to evaluate the effect of dominant lower limb on the correlation between some of the dynamic variables of ankle joint and center of mass during quiet standing balance control. Methods: Twelve healthy females with no known neurological or musculoskeletal disorders, with the mean age of 26±3.5 years, participated in this study. Motion analysis system, force ...

  Background: Ankle fractures, especially those resulting from external rotation mechanisms are associated with injury to the distal tibiofibular syndesmosis. Some authors have recommended performing CT scanning after open ankle surgery to evaluate the reduction of syndesmosis. In this current study, we aimed to investigate the sensitivity of plain radiography in diagnosing syndesmosis malreduc...

A nkle arthritis is nine-times less common than hip or knee arthritis [2]. When ankle arthritis does occur, it causes pain and severe disability. Ankle arthritis is as physically debilitating as end stage renal disease, congestive heart failure, cervical spine arthritis, and radiculopathy [5]. The treatment options for severe ankle arthritis have changed during the past 10 to 15 years. Currentl...

QUESTIONS Is loss of proprioception or loss of motor control related to functional ankle instability? Are proprioception and motor control related? Is there any difference in proprioception or motor control between ankles with different severity of functional ankle instability? DESIGN Cross-sectional, observational study. PARTICIPANTS Twenty people aged between 18 and 40 years with function...

Total ankle arthroplasty was developed to reduce pain and retain motion of the ankle joint in patients with osteoarthritis much like its total hip and knee counterparts. Orthopaedic surgeons are well equipped to evaluate and treat patients with end-stage hip or knee arthritis; however, the management of patients with ankle arthritis represents a challenge to both general orthopaedic surgeons an...

RISK FACTORS – ACUTE LATERAL ANKLE SPRAIN: Clinicians should recognize the increased risk of acute lateral ankle sprain in individuals who (1) have a history of a previous ankle sprain, (2) do not use an external support, (3) do not properly warm up with static stretching and dynamic movement before activity, (4) do not have normal ankle dorsiflex-ion range of motion, and (5) do not participate...
