The activation energies associated with the formation of a superlattice intrinsic stacking fault (SISF) from an antiphase domain boundary (APB) and the formation of a superlattice extrinsic stacking fault (SESF) from a complex stacking fault (CSF) in g 0 phase of Ni-based superalloys are calculated using a microscopic phase field dislocation model in combination with the nudged elastic band (NE...

Recent studies of passive myocardial mechanics have shown that strain softening behavior is present during both inflation of isolated whole rat hearts and shearing of tissue blocks taken from the left ventricular free wall in pigs. Strain softening is typically manifested by a stiffer force-extension relation in the first deformation cycle relative to subsequent cycles and is distinguished from...

[1] The slip behavior of major faults depends largely on the frictional and hydrologic properties of fault gouge. We report on laboratory experiments designed to measure the strength, friction constitutive properties, and permeability of a suite of saturated clay-rich fault gouges, including: a 50:50% mixture of montmorillonite-quartz, powdered illite shale, and powdered chlorite schist. Fricti...

In this study, the compression behaviour of unsaturated damaged COx claystone is investigated by performing high pressure oedometer tests with controlled suction. The samples were prepared shearing in triaxial conditions. Four conducted using different suctions. effects suction and damage on swelling oedometer. Results show that intact exhibits a larger strain than one at same imposed lower dis...

This paper presents a novel image watermarking resynchronization technique in discrete wavelet trans-form (DWT) domain. Rotation and shearing attacks desynchronizing watermark model in DWT domain are given respectively. According to these models, two corresponding watermarking resynchronization algorithms are proposed. The ideal watermark can be extracted from the resynchronized watermarked ima...

Chromatin shearing is the first critical step to provide sensitive and reproducible results in chromatin immunoprecipitation (ChIP) experiments. Adaptive Focused Acoustics (AFA) acoustic technology provides precise control over mechanical shearing and thermal control during processing to deliver high quality chromatin for the most sensitive results, in a highly reproducible manner. Optimizing t...

The discovery and understanding of gecko 'frictional-adhesion' adhering and climbing mechanism has allowed researchers to mimic and create gecko-inspired adhesives. A few experimental and theoretical approaches have been taken to understand the effect of surface roughness on synthetic adhesive performance, and the implications of stick-slip friction during shearing. This work extends previous s...

Background: Musculoskeletal disorders (MSDs) are among the most prevalent pains which could be ignited via material handling. Backpack wearers are among those who may carry heavy loads. Since MSDs mainly originate in school-aged children, students (as the largest group of backpack wearers) are considered more important. The purpose of this study is to design a backpack based on minimization of ...
