Varicose veins (VVs) of pelvic origin are one of the clinical presentations of pelvic venous disorders (PeVD) and are increasingly being diagnosed in patients in phlebological offices these days.To investigate VVs potentially resulting from pelvic vein incompetence (PVI), a usual full duplex ultrasonography (DUS) of lower extremity veins in the upr
Background: Strength training has been a common intervention used to improve neuromuscular activity within the synergic and/or agonist-antagonist muscles.This study aimed to evaluate simultaneous electrical activity of quadriceps and hamstring muscles after strength eccentric training versus concentric training.Methods: This experimental study has
The wheel-rail wear was predicted for modern trams with independently rotating wheelset running on a groove-shaped rail.The tram vehicle-track coupled dynamics model, considering the wheel-rail multi-point contact, was developed using software UM to evaluate the dynamic responses of the vehicle and track.Hertz contact theory, the FastSim algorithm,
