In land reclamation projects, the vacuum preloading method has been widely used to strengthen dredged fills by removing water. However, during improvement process, clogging inevitably occurs in drains and soils, hindering water drainage causing inhomogeneous consolidation results. Therefore, it is essential evaluate effect of on behavior slurry at different radii. this study, analytical solutio...

in this paper, the effect of prestrain on strain aging of low carbon steels, in the temperatures of 100°c and 200°c and the aging time of 50 minutes, and also the effect of aging temperature on strain aging in a constant aging time and prestrain, are investigated. the results of experiments show that with increasing the amount of prestrain, the increase in yield stress and ultimate tensile stre...

aim :  the aim of this study was to investigate the in vitro inhibitory effect of probiotic e.coli nissle 1917 (ecn) strain against pathogenic bacteria isolated from patients with diarrhea. background : probiotics are viable microorganisms that are shown to have beneficial effects on human health. ecn is a typical example of probiotics; however, there are few reports of it being administered fo...

a purification procedure of pertussis toxin (pt) from submerged culture of bordetella pertussis (b.pertussis) strain 134 using adsorption and affinity chromatography was discussed. the yield of the resulting pt was approximately 37.5mg/l of concentrated culture supernatant. the polypeptide pattern of the purified pt was investigated by sds-page and showed five bands between 11 to 26 kda using l...

Cyclic strain regulates many vascular smooth muscle cell (VSMC) functions through changing gene expression. This study investigated the effects of cyclic strain on protease-activated receptor-1 (PAR-1) expression in VSMCs and the possible signaling pathways involved, on the basis of the hypothesis that cyclic strain would enhance PAR-1 expression, reflecting increased thrombin activity. Uniaxia...

in this paper, the solution of a moving volterra-type screw dislocation in an orthotropic layer, bonded between two piezoelectric layers is obtained using complex fourier transform. the dislocation solution is then employed as strain nuclei to derive singular integral equations for a medium weakened by multiple moving cracks. these equations, which are classified as, cauchy singular equations, ...

The effect analysis of strain rate on power transmission tower-line system under seismic excitation is studied in this paper. A three-dimensional finite element model of a transmission tower-line system is created based on a real project. Using theoretical analysis and numerical simulation, incremental dynamic analysis of the power transmission tower-line system is conducted to investigate the ...
