Quasi-cleavage Processes Driven by Dislocation Pileups
The present paper explores quasi-cleavage processes driven by dislocation pileups against a Dislocation Free Zone (DFZ). The nanoscopic growth of the main crack consists of sequences of nanocrack formation in DFZ and its subsequent linkage with the main crack. Under mode I loading, the equilibrium locations of individual dislocations and the equilibrium number of dislocations are determined by ...
متن کاملAdipoRon may be benefit for atherosclerosis prevention
Atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atheros...
متن کاملAn analysis of edge dislocation pileups against a circular inhomogeneity or a bimetallic interface
Equilibrium configurations of edge dislocation pileups against a circular inhomogeneity or a bimetallic interface are determined numerically for a given number N of dislocations, the applied shear stress τ , the size of the inhomogeneity, and the degree of material disparity. The increase of applied stress moves a pileup closer to the inhomogeneity and increases the density of dislocations with...
متن کاملCerebral white matter lesions may be partially reversible in patients with carotid artery stenosis.
Contrary to the common belief that age-related WMLs (also known as leukoaraiosis) are a progressive condition, a case of partial reversal of WMLs shortly after carotid artery stenting is described. A 75-year-old man presented with frequent TIAs, which were attributed to right ICA stenosis. He subsequently underwent successful carotid artery stenting. Follow-up MR imaging a week after the proced...
متن کاملIL-8 May Be the Target of Arsenic in Human Breast Milk
Background and Aims: The critical aim of this study was to evaluate the effects of breast-milk contamination with Nickel and Arsenic, as well as aflatoxin M1 (AFM1) on the milk levels of IL-6 and IL-8. Materials and Methods: Breast milk was collected from 76 mothers on the 30th day post-parturition and milk levels of AFM1, Nickel, Arsenic, IL-6 and IL-8 were evaluated. Results: The results s...
