In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

PURPOSE There is ambiguity about using the term "knuckle pads" in Dupuytren's disease (DD). Clear definitions of dorsal knuckle pads and nodules are lacking and the prevalence of these 2 entities has not been determined. We sought to define these terms and investigate the distribution and frequency of dorsal knuckle pads and dorsal nodules in the normal volunteers and in DD patients. METHODS ...

pachydermodactyfy is a rare, benign mostly asymptomatic digital fibromatosis, characterized by swelling on the back and sides of proximal phalanges and (or) proximal interphaiangeal joints. it occurs predominantly in young males although a few women including a familial case were recently described. a history of repeated trauma is sometimes available, but the etiology remains unknown. we report...

Injuries to the extensor mechanisms of the fingers can be career-ending in professional athletes if not treated appropriately. We identified 8 professional athletes who underwent 11 direct metacarpophalangeal joint extensor mechanism repairs including centralization of the extensor tendon and sagittal band repair between 1989 and 1994. Success of the operative procedure was determined by the at...

Computational steering allows researchers to monitor and manage long running, resource intensive applications at runtime. Limited research has addressed high performance computational steering. High performance in computational steering is necessary for three reasons. First, a computational steering system must act intelligently at runtime in order to minimize its perturbation of the target app...
