It has previously been speculated that the occurrence and severity of lateral ankle sprain injuries is linked to excessive shoe–surface friction. Especially, parts shoe outsole are suggested play an important role in such scenarios but have never quantified a systematic manner. Therefore, purpose this study was investigate variation friction indoor sport shoes with foot orientation compare it t...

Introduction: Evidence concerning the role of isolated lateral retinacular release (LRR) for patellar compression syndrome (LPCS) dates back at least three decades. Appropriate indications, execution and outcomes still remain unclear controversial. The present investigation analyzed midterm result arthroscopic LRR LPCS in a cohort patients who underwent such procedure our institution. Material ...

one of the most common methods for controlling and increasing maneuverability of projectiles, especially the ones which move at high altitude and in low density air, is using lateral or reaction jets. the resultant force of the reaction jet is related to the jet and flow parameters. for finding their relation experimental, numerical, and analytical methods have been used. in order to change the...
