In open pit mines, the slope stability of benches, inter-ramps, and overall is vital not only for economy extraction process but also safety personnel equipment. Geological discontinuities, geometry, other factors can induce different failure modes in hard rock masses such as planar, wedge sliding, toppling. Hence, analysis must be carried out carefully using a suitable technique by considering...

For the purpose of exploring deformation characteristics of jointed rock masses, influence of joint inclination and confining pressure on the mechanical behavior of discontinuous rock a series of compression tests were conducted under satisfactory testing conditions on three types of sandstone from various locations. Three groups of jointed specimens were used in this research, including specim...

Introduction: Myostatin regulates skeletal muscle mass and adipogenesis, but serum response to continuous and discontinuous exercises training it has not been studied in menopause and menstrual groups of women. The purpose of this study was to investigate the serum response of myostatin, insulin and glucose to use four different aerobic exercises training in menopause and menstrual groups of wo...

A Brazilian Tensile Strength (BTS) laboratory test for meta-andesite was modeled using a Finite/Discrete Element Method (FDEM or FEM-DEM). These hybrid methodologies allow modeling the transition from continuous to discontinuous that happens on mechanical tests of rock samples. This article presents calibration and simulation BTS some parameters previously calibrated UCS same material. Irazu, t...
