Male black bears undergo seasonal changes in testicular activity. The testes are fully functional from May through July, regress from July through December, and recrudesce from January until May. The mechanisms responsible for the initiation of testicular recrudescence in the bear are unknown. The o

Despite the widespread use of porcine bone as a substitute for human bone in the development of surgical technique and the use of fixation devices, relatively few studies have reported on the mechanical behaviour of porcine long bones. Regional variation in the mechanical properties of cortical bone
Zirconia has received special attention, mainly because of its high strength and toughness. However, there is some controversy about the time-dependent deterioration of its mechanical properties. To examine the change in mechanical properties of zirconia ceramics in uivo and in uituo, tetragonal zir
