DYNAMIC TENSILE - FAILURE - INDUCED VELOCITY DEFICITS IN ROCK Allan
&bstracL Planar impact experiments were employed to induce dynamic tensile failure in Bedford limestone. Rock discs were impacted with aluminum and polymethyl methacralate (PMMA) flyer plates at velocities of 10 to 25 m/s. Tensile stress magnitudes and duration were chosen so as to induce a range of microcrack growth insufficient to cause complete spalling of the samples. Ultrasonic Pand S-wave...
متن کاملDynamic changes in conduction velocity and gap junction properties during development of pacing-induced heart failure.
End-stage heart failure (HF) is characterized by changes in conduction velocity (CV) that predispose to arrhythmias. Here, we investigate the time course of conduction changes with respect to alterations in connexin 43 (Cx43) properties and mechanical function during the development of HF. We perform high-resolution optical mapping in arterially perfused myocardial preparations from dogs subjec...
متن کاملFlexural Toppling Failure in Rock Slopes: From Theory to Applications
Toppling failure is one of the most common modes of failure of rock slopes in layered rock strata. Flexural toppling is one of the well-known modes of the failure. This type of failure occurs due to bending stress. In this article, a brief yet comprehensive review of toppling failure is presented. Firstly, the conditions and general mechanism of the failure are described. Then, experimental, th...
متن کاملRock Failure Energies and Failure Processes
Carving rock by indenting sharp objects into the surface under an impact force has been a favored method of fragmentation for millenia . However, as rock gets harder the lifetime of these sharp tools becomes short and, in a compromise hardened bits of rounder contour have become more common, particularly when driven by mechanical power. To better understand the behavior of these newer generatio...
متن کاملNaringin ameliorates cognitive deficits in streptozotocin-induced diabetic rats
Objective(s):Previous research demonstrated that diabetes is one of the leading causes of learning and memory deficits. Naringin, a bioflavonoid isolated from grapefruits and oranges, has potent protective effects on streptozotocin (STZ)-induced diabetic rats. Recently, the effects of naringin on learning and memory performances were monitored in many animal models of cognitive impairment. Howev...
