This study presents analysis of two types experimental test related to the crack propagation in concrete specimens subjected high-sustained loading levels and quasi-static loadings. The concept equivalent length is introduced perform this analysis. Even though partial, it shows influence rate conditions on process rate. result that, domains low very rates, mechanical characteristics linked crac...

The risk of sustaining tibia fractures as a result of a frontal crash is commonly assessed by applying measurements taken from anthropometric test devices to the Tibia Index. The Tibia Index is an injury tolerance criterion for combined bending and axial loading experienced at the midshaft of the leg. However, the failure properties of human tibia compact bone have only been determined under st...

Prostacyclin (prostaglandin I2, PGI2) has a variety of functions, including inhibition of smooth muscle cell proliferation, vasodilation, and antiplatelet aggregation. PGI2 production in endothelial cells has been reported to increase biphasically after shear loading, but the underlying mechanism is not well understood. To clarify the mechanism for the second phase of PGI2 upregulation, we exam...

BACKGROUND The purpose of the present study was to compare the mechanical static and fatigue strength of the size 2 osteotomy plate "Activmotion" with the following five other common implants for the treatment of medial knee joint osteoarthritis: the TomoFix small stature, the TomoFix standard, the Contour Lock, the iBalance and the second generation PEEKPower. METHODS Six fourth-generation t...
