objective: the present study aimed to determine whether castration altered osmotically stimulated vasopressin (vp) release and urinary volume and what is the role of endocrine-stress axis in this process. materials and methods: totally 108 mice were studied in two main groups of castrated (n=78) and control (n=30). each group was extracted by acute cold stress (4◦c for 2h/day), restraint stress...

using piezoelectric patches the stress concentration around a hole on a plate under tension is reduced and controlled. to attain the reduction in stress two placements for piezoelectric patches is investigated. the first location is top/bottom of the hole with compression induced strain and the second is left/right of the hole with tension induced strains to control the stress flow. the result ...
