Distal radius (Colles') fractures are a common fall-related injury in older adults and frequently result in long-term pain and reduced ability to perform activities of daily living. Because the occurrence of a fracture during a fall depends on both the strength of the bone and upon the kinematics and kinetics of the impact itself, we sought to understand how changes in bone mineral density (BMD...

A tire’s three-dimensional stress for pavement is an important cause of asphalt disease. In order to study the contact distribution between tire and under real conditions, a sensor that can measure tri-axial synchronously designed, complete measurement system established. The variation trend value steady rolling were obtained, characteristics analyzed. results show in three directions near shou...
