Background: Joint trauma and injury are the most common causes of dynamic instability. Dynamic instability has a great effect on the lumbar spine, due to its three-dimensional motions. The greatest amounts of compression and shearing force are imposed at the points of maximum torque and velocity. The changes in these phase angles upon bearing various loads can cause some pathologic conditions. ...
Propagation of Electromagnetic wave in a plasma in the equilibrium state can cause instability. Investigating the situations in which this kind of instability occurs and grows is an important issue. In this paper, Raman instability in plasma is analyzed by particle simulation method. In terms of physical investigation, plasma is a very complicated environment and experimentally too expensive. ...
The fracture of brittle amorphous materials is an especially challenging problem, because the way a large object shatters is intimately tied to details of cohesion at microscopic scales. This subject has been plagued by conceptual puzzles, and to make matters worse, experiments seemed to contradict the most "rmly established theories. In this review, we will show that the theory and experiments...
the changes in todays world organization, to the extent that instability can be characterized with the most stable organizations called this afternoon. if you ever change management component, an additional value to the organization was considered, today, these elements become the foundation the organization is survival. the definition of the entrepreneur to identify opportunities to exploit a...
Introduction: The purpose of this study is to investigate the effect of 8 weeks virtual reality training on static and dynamic balance and performance of in male athletes with functional ankle instability Research Methodology: For this research, 30 volleyball, basketball, football and handball players ranged from 18 to 25 years were selected purposefully from Tehran province league male a...
Dielectric elastomers, as an important category of electroactive polymers, are known to have viscoelastic properties that strongly affect their dynamic performance and limit their applications. Very few models accounting for the effects of both electrostatics and viscoelasticity exist in the literature, and even fewer are capable of making reliable predictions under general loads and constraint...
Background : Acute lateral ankle sprains are the most common injuries in sports and routine activities of life. The purpose of this study was an overview of EMG activation of postural stabilizer muscles in dynamic balance test to provide clinicians with biomechanical perspectives of the local and global effects of ankle instability. Methods : The sinker– card protocol was used as a dynamic ...
