The main goal of using dual core spun yarn is to take advantage all properties its different components. Dual-core yarns comprising three components are currently in vogue. They combine the pleasant wear elastic with high dimensional stability. production these a challenging process even at spinning stage, but they making demands market. Such stretchable produced modified Ring frame. In this sy...

conclusions the results clarified a deep perception of participants’ experiences after disaster. the path of life recovery after disasters involves participants’ striving to achieve a comprehensive health recovery, which starts with the need for all-inclusive health recovery as a main concern; this is the motivator for a responding strategy. this strategy is participatory, and the process is pr...

Water-soluble polymers are known to be used in chemically enhanced oil recovery (EOR) processes, but their applications are limited in high-temperature and high-salinity oil reservoirs because of their inherent poor salt tolerance and weak thermal stability. Hydrophobic association of partially hydrolyzed polyacryamide (HAHPAM) complexed with silica nanoparticles to prepare nano-hybrids is repo...

We present a constitutive model capturing some of the experimentally observed features of soft biological tissues: nonlinear viscoelasticity, nonlinear elastic anisotropy, and nonlinear viscous anisotropy. For this model we derive the equation governing rectilinear shear motion in the plane of the fiber reinforcement; it is a nonlinear partial differential equation for the shear strain. Special...

various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

Abstract Active fibers can serve as artificial muscles in robotics or components of smart textiles. Here, we present an origami hand robot, where single control the reversible movement fingers. A recovery/contracting force 0.2 N with a work capacity 0.175 kJ kg ?1 was observed crosslinked poly[ethylene- co -(vinyl acetate)] (cPEVA) fibers, which could enable bending fingers by contraction upon ...

recovery is a part of disaster management cycle during which repair and reconstruction takes place, and individuals, groups, and communities retake what they have lost and ideally the risk of future incidents reduces. life recovery is a subjective and multidimensional issue influenced by various factors, whereas valid measurable indicators in evaluating the recovery after disasters are helpful....

It is shown that the pseudo-elastic response in a series of Ti–Mo–V–Nb–Al alloys with 8–11 wt.% Mo is highly sensitive to both composition and heat treatment. Recovery of up to 3.0% strain has been observed but it appears that this may not be due to reversible formation of a00 martensite. 2003 Acta Materialia Inc. Published by Elsevier Ltd.
