abstract background: restless leg syndrome prevalence is high among the patients undergoing hemodialysis. due to several side effects of medicational treatments, the patients prefer non-medicational methods. therefore, the present study aimed to investigate the effects of two methods of reflexology and stretching exercises on the severity of restless leg syndrome among patients undergoing hemod...

The inspiration driving this article is to explore the impacts of electromagnetic field and heat source/sink on two dimensional nanofluid flow over a stretching cylinder. effectively controlled model utilized in current assessment incorporates nanoparticle fraction model. nanoparticles specified here are Cobalt $Co$ Gadolinium $Gd$. Cobalt, shunt material thermomagnetic generator. Gadolinium, $...

The present study is about the numerical analysis of Casson fluid’s boundary layer slip flow beneath impact suction/blowing past a permeable cylinder stretching exponentially. modeled partial differential equations are transformed to nonlinear ordinary by applying appropriate transformation. Keller box procedure, tool famous for its achievements, used. relevant physical parameters like suction,...

We revisit the rapid stretching of a liquid filament under the action of a constant imposed tensile force, a problem which was first considered by Matta & Tytus [JNNFM vol. 35, pp 215-229, 1990]. A liquid bridge formed from a viscous Newtonian fluid or from a dilute polymer solution is first established between two cylindrical disks. The upper disk is held fixed and may be connected to a force ...

Pure diblock copolymer melts exhibit a narrow range of conditions at which bicontinuous and cocontinuous phases are stable; such conditions and the morphology of such phases can be tuned by the use of additives. In this work, we have studied a bidisperse system of diblock copolymers using theory and simulation. In particular, we elucidated how a short, lamellar-forming diblock copolymer modifie...

DNA compaction in a bacterial cell is in part carried out by entropic (depletion) forces induced by "free" proteins or crowding particles in the cytoplasm. Indeed, recent in vitro experiments highlight these effects by showing that they alone can condense the E. coli chromosome to its in vivo size. Using molecular dynamics simulations and a theoretical approach, we study how a flexible chain mo...

Uncapped, hollow polymeric microstructures were fabricated on a silicon substrate using electric field induced stretching and detachment. Initially, square or cylinder microposts were generated using a solvent-assisted capillary molding technique, and a featureless electrode mask was positioned on the top of the microstructure with spacers maintaining an air gap (∼20 μm). Upon exposure to an ex...

This study investigates the mixed convection flow of Jeffrey liquid by an impermeable inclined stretching cylinder. Thermal radiation and non-uniform heat source/sink are considered. The convective boundary conditions at surface are imposed. Nonlinear expressions of momentum, energy and concentration are transformed into dimensionless systems. Convergent homotopic solutions of the governing sys...

The morphology transition due to midblock swelling with low-molecular-weight homopolymer polystyrene of an ABA-type triblock copolymer polyparamethylstyrene-block-polystyrene-block-polyparamethylstyrene at the buried silicon substrate interface is studied as a function of different substrate surface treatments. With grazing incidence small-angle neutron scattering (GISANS), high interface sensi...
