We report on the low-cycle fatigue behavior of single-phase, face-centered cubic CoCrNi and CoCrFeMnNi at room temperature. Both alloys manifest cyclic hardening followed by softening a near steady state until failure. exhibits higher strength, lower inelastic-strain, longer lifetime than CoCrFeMnNi. For both alloys, microstructural investigations reveal no noticeable changes texture, grain siz...

Aseptic loosening and bacterial infections are the two main causes of failure for metallic implants used joint replacement. A coating that is both bioactive possesses antimicrobial properties may address such shortcomings improve performance implant. We have sought to study combining hydroxyapatite-based nanoparticles or coatings with baicalein, a plant-extracted molecule antibacterial antioxid...

Objectives: Digoxin is an antiarrhythmic drug with a narrow therapeutic range and used in clinical conditions such as heart failure atrial fibrillation. The planar frontal QRS-T angle reflects the deviations between depolarization repolarization of ventricles, it has been reported that increase this associated mortality. In our study, relationship digoxin use blood level was investigated. Metho...

Failure envelope formulations are typically employed to assess the ultimate capacity of foundations under combined loading and for incorporation in macro-element models. However, complex interaction between each load component, especially six degree freedom (6DoF) loading, means that determining satisfactory is often a process. Previous researchers have identified this difficulty as an obstacle...

We modeled the sensitivity of six ice-cemented slope deposits from the western McMurdo Dry Valleys, Antarctica to failure by shallow, thaw-induced planar sliding. The deposits examined have purportedly remained physically stable, without morphologic evidence for downslope movement, for millions of years. Could they fail in the near future from greenhouse-induced warming? To address this questio...

The purpose of this research is to provide a deeper understanding of the planar high- symmetry configuration instability. In the ideal case, the distortion corresponds to the movements of nuclei along normal modes that belong to non-totally symmetric irreps of the high symmertry (HS) point group of molecule. The analysis of the structural distortion from the HS nuclear arrangements of the JT ac...

‎let $g$ be a finite group which is not a cyclic $p$-group‎, ‎$p$ a prime number‎. ‎we define an undirected simple graph $delta(g)$ whose‎ ‎vertices are the proper subgroups of $g$, which are not contained in the‎ ‎frattini subgroup of $g$ and two vertices $h$ and $k$ are joined by an edge‎ ‎if and only if $g=langle h‎ , ‎krangle$‎. ‎in this paper we classify finite groups with planar graph‎. ‎...

metal complexes, ml (m=ni, cu, co and zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units n-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(hl1) with 2-pyrroleca-rbaldehyde. the complexes have been characterized by elemental analysis, ir, 1h nmr and uv spectroscopy. the crystal structure of the ni(ii) complex has been determine...

This study investigates the effect of stress triaxiality on failure mechanisms an-isotropic perfect and imperfect planar FCC (Face Centred Cubic) truss lattice metamaterials. Three types imperfection have been considered in numerical modelling, namely, distorted struts, missing strut diameter variation. In order to maintain constant during simulations, a novel framework was developed overcome c...
