We consider the nucleation of instability on a slip-weakening fault subjected to a heterogeneous, locally peaked “loading” stress. That stress is assumed to gradually increase due to tectonic loading but to retain its peaked character. The case of a linear stress versus slip law is considered in the framework of two-dimensional quasi-static elasticity for a planar fault. Slip initiates when the...

Market weight pigs are subjected to numerous stressors during the marketing process from loading at the farm to stunning at the packing plant. These stressors have important implications for animal well-being and fresh pork quality traits. The objectives of this presentation are to review: 1) pre-harvest stressors in pigs; 2) common measures of stress during handling and transportation; and 3) ...

Objective: The aim of the study was to explore mutual relationship between oxidative stress, inflammation and metabolic biomarkers in subjects with prediabetes (PRE), newly diagnosed type 2 diabetes patients (NT2D) overt (T2D) using principal component analysis (PCA) as a thorough statistical approach.
 Patients Methods: Glycated hemoglobin, lipid parameters, (IL-6, CRP fibrinogen) stress ...

It is difficult to conduct cyclic tensile fatigue tests for fine ceramics because of its high brittleness, and a little eccentricity of loading axis and gripping device gives inaccurate strength data. So, a major part of cyclic fatigue tests have been carried out under bending load conditions, for the allowance of misalignment of loading axis is generous to some extent in the case of bending fa...

Palmoplantar hidrosis is common in patients who are susceptible to strains on the autonomic nervous system, and stress and mental strain have been proven to produce sweating in this population. Shigyaku-san (Sini san, TJ-35: Tsumura & Co.) is effective for relieving stagnation of 'liver Qi and vital energy' in traditional Chinese medicine theory; this brings about improvement of palmoplantar hi...

Orthopaedic implants experience large cyclic loads, and pre-clinical analysis is conducted to ensure they can withstand millions of loading cycles. Acetabular cup developments aim to reduce wall thickness to conserve bone, and this produces high pre-stress in modular implants. As part of an implant development process, we propose a technique for preclinical fatigue strength assessment of modula...

BACKGROUND We hypothesized that using a cadaveric Lisfranc ligamentous injury model, abduction stress would provoke greater post-injury motion than axial weightbearing between the medial cuneiform (MC1) and the base of the second metatarsal (MT2). Second, we hypothesized that both a tensioned suture-button device and a rigid screw fixation method could maintain a reduction and similarly restrai...

Underground excavation is a necessary process for constructing mines, tunnels and depots in granite rock mass. In this study, the numerical specimens were established by discrete element method confirmed laboratory experiments order to investigate peak stress, cracking development failure properties of pre-holed under coupled biaxial loading unloading conditions. The results show that, containi...

background: lipid peroxidation is a free radical-generating process which occurs on every membranous structure of the cell. free radicals are known to be involved in a number of human pathologies including atherosclerosis. the purpose of this cross-sectional study was to examine the association between pre-hypertension status and oxidative stress markers [total antioxidant capacity (tac) and ma...
