In this study, the well-established pseudo-static approach along with horizontal slices method (HSM) is employed to investigate seismic internal stability of geosynthetic-reinforced earth slopes. Previous simple HSM analyses were based on a primary assumption stating that normal inter-slice forces are exerted mid-length sections. However, simplifying could give rise substantial errors in calcul...

This study aims to investigate the utilization of recycled textile waste fiber (RTWF) as reinforcement in cementitious lightweight composite mortars. The effect RTWF percentage on mortar (CLCM) consistency, plastic and dry set density, splitting tensile compressive strength was measured. In particular, structural mechanical properties hardened examined detail. Mohr-Coulomb Failure Criterion use...

Induced seismicity associated with underground space creation and resource extraction has become a matter of global concern. However, our ability to predict mitigate anthropogenic geohazards is still woefully inadequate. This review provides an overview unloading-induced highlights the mechanisms behind fault instability from view rock mechanics. Based on numerous cases, reduction rotation in s...

x-100 steel is one of the most recently developed materials for production of gas transportation pipelines. this material is severely anisotropic. smooth and notched round bars with different notch radius and flat notched specimens with different notch radius and notch depth in tension are tested to characterize the failure of this material under quasi-static loading condition. triaxiality fact...

Impoundment of the Zipingpu reservoir (ZR), China, began in September 2005 and was followed 2.7 years later by the 2008 Mw 7.9 Wenchuan earthquake (WE) rupturing the Longmen Shan Fault (LSF), with its epicenter ~12 km away from the ZR. Based on the poroelastic theory, we employ three-dimensional finite element models to simulate the evolution of stress and pore pressure due to reservoir impound...

Weyl semimetals (WSMs) constitute a 3D phase with linearly dispersing Weyl excitations at low energy, which lead to unusual electrodynamic responses and open Fermi arcs on boundaries. We derive a simple criterion to identify and characterize WSMs in an interacting setting using the exact electronic Green's function at zero frequency, which defines a topological Bloch Hamiltonian. We apply this ...

A new species of Seticornuta from Brazil is described and illustrated, the first record of this genus for the Brazilian fauna. This new species was found in a study that aimed to enhance knowledge of the Brazilian fauna of Metopiinae, analysing samples from the hydrographic basin of Rio Mogi Guaçu. A diagnosis, along with distribution information for Seticornuta species are provided.

BACKGROUND Since previous studies suggest the emergency department (ED) misdiagnosis rate of heart failure is 10-20% we sought to describe the characteristics of ED patients misdiagnosed as non-decompensated heart failure in the ED. METHODS We analyzed a prospective convenience sample of 439 patients at 4 emergency departments who presented with signs or symptoms of decompensated heart failur...

The surface morphology of joints directly determines the contact area and peak shear strength rock in shearing. This research gives a detailed description three-dimensional roughness parameters proposed by Grasselli, discusses characteristics parameter C different ranges. Quoting Xia's direct test data, relationship strength, strength/normal stress, residual dilation with normal stress are stud...
