use of plant growth promoting bacteria (pgpb) and high quality of seed as agricultural inputs play important roles in sustainable crop production. to study the effects of different levels of seed aging and pgpb's application on field emergence, seedling establishment and yield of two red kidney bean cultivars in field conditions, an experiment was carried out as factorial based in a rcbd d...

This work presents modeling of experiments on a balanced biaxial (BB) pre-strained AA5754 alloy, subsequently reloaded uniaxially along the rolling direction and transverse direction. The material exhibits a complex plastic deformation response during the change in strain path due to 1) crystallographic texture, 2) aging (interactions between dislocations and Mg atoms) and 3) recovery (annihila...

This study demonstrates a two-step approach that enables quantification of concrete printability through dynamics mode rheological measurements; I) modeling shearing history during extrusion; II) monitoring the hardening evolution deposited material by applying strain smaller than critical strain. It is shown removed imposing pre-shearing above strain, and zero value yield stress measured for a...

background: mechanotransduction plays a pivotal role in remodeling and repair of skeletal tissues. this mechanism has been widely used in bone tissue engineering especially under in vitro conditions. to date, various stem cells have been used for this purpose. the present study was thefirst to evaluate the effect of mechanical loading on differentiation of human endometrial stemcells (hescs) to...

determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. in this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. the critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. in a...

in this research, the bending analysis of rectangular nanoplates subjected to mechanical loading is investigated. for this purpose, the strain gradient elasticity theory with one gradient parameter is presented to study the nanoplates. from the best knowledge of authors, it is the first time that the exponential shear deformation formulation based on strain gradient elasticity theory is carried...
