Power assessment of lower limbs and strength asymmetry of soccer goalkeepers

Acta Universitatis Palackianae Olomucensis. Gymnica, 2013
BACKGROUND: Effective execution of vertical jump depends on the explosive power of lower limbs and their symmetrical integration mainly. Assessment of lower extremity bilateral asymmetries in soccer players is important for both injury prevention and ...

Numerical Simulation of Aerodynamics of Train with Broken Windows

Journal of Applied Fluid Mechanics, 2020
Window glass of the train was broken several times when running in the strong wind/sandy areas, causing safety risks to passengers and serious problems to the operation of the train. The aerodynamic performances of the train with broken windows in strong

3D physical modeling of anisotropic grain growth at high temperature in local strong magnetic force field

Science and Technology of Advanced Materials, 2008
A new mechanism based on the effect of local magnetic forces on diffusing ions around a growing ferromagnetic precipitate is proposed. A 3D simulation based only on physical parameters is undertaken in which main assumption is of interface limited growth
