Given shale's potential to serve as both a caprock for geological carbon sequestration and the host nuclear waste disposal, this study focuses on structural characterization around 1.5–3 m thick fault within Opalinus Clay rock petrophysical of core. Seven boreholes were drilled at Mont Terri Rock laboratory in late 2018 constrain orientation so-called ‘Main Fault’ several fracture families core...

Background: Apart from the mortality, road traffic injuries are associated with significant morbidities. This study has aimed to examine the pattern of traffic accident-related extremity fractures/dislocations and their related disabilities. Methods: A retrospective hospital-based study was conducted to assess the characteristics of limb fractures/dislocations among road traffic accident victi...

The Lower Permian Fengcheng Formation in the Mahu Sag develops a set of organic-rich alkaline lacustrine shale strata, which is key area for oil exploration and development. As an important storage space seepage channel reservoirs, natural fractures have impact on enrichment, production development effect. In this study, types characteristics were first analyzed using core, thin section imaging...

background: prevalence of fall-related mortality is rising in the elderly population. falling is one of the causes of the murderous and non-murderous injuries in the elderly population which can lead to disability, dependence and decline of quality of life. fractures constitute a major part of the fall-related injuries. the present study is designed to investigate the prevalence of fall-related...

different methods for detecting broken bars in induction motors can be found in literature. many of these methods are based on evaluating special frequency magnitudes in machine signals spectrums. current, power, flux, etc are among these signals. frequencies related to broken rotor fault depend on slip. in industrial environment due to some phenomena - such as load oscillation, other faults an...

Field observations of active and fossil natural geothermal fields indicate that fluids are primarily transported along dikes fault zones. Fluid transport (commonly through fractures at their margins) is controlled by the cubic law where volumetric flow rate depends on aperture fracture in 3rd power. Dikes (and inclined sheets) also act as heat sources for fields. In high-temperature volcanoes I...

 Background: Prevalence of fall-related mortality is rising in the elderly population. Falling is one of the causes of the murderous and non-murderous injuries in the elderly population which can lead to disability, dependence and decline of quality of life. Fractures constitute a major part of the fall-related injuries. The present study is designed to investigate the prevalence of fall-relate...

This paper discusses Coulomb failure criteria for brittle deformation of intact rock and fault gouge. Data are presented from laboratory experiments designed to identify the critical gouge layer thickness required to effect a transition from the standard Coulomb criterion to a modified failure law (referred to as Coulomb plasticity) appropriate for simple shear of a gouge layer. Experiments wer...
