The three main needs of athletes are performance, injury protection and comfort. Footwear enhances performance through increases in traction and biomechanical efficiency. Footwear protects the foot at the interface with the ground and the entire body against the forces resulting from repeated feet-ground impacts. Footwear can also reduce injuries by correcting for the locomotor system static st...

Abstract At present, PWM rectifier is widely used in various high power and voltage situations because of its energy, low harmonic content, constant bidirectional energy. The energy supply system subway traction based on shows the topology a dual transformer with three winding transformers four rectifiers parallel, which superior to modular model. Finally, correctness control strategy verified ...

A new technique of osteotomy distraction osteogenesis (ODO) and sutural distraction osteogenesis (SDO) by the use of bone-borne traction hooks is presented. The technique of osteotomy plus distraction osteogenesis is suitable for adult patients. The technique of sutural distraction osteogenesis is suitable for young patients, ages 6 through 12 years. The distraction system consists of a face-bo...

purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...
