The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...

A numerical dynamic-aerodynamic interface for simulating the separation dy­n­a­m­ic­s of co­n­­s­t­r­a­i­ned strap-on boosters jettisoned in the atmosphere is presented. A 6-DOF multi body dynamic solver ،using Constraint For­ce Equation Methodology is coupled with a numerical time dependent Euler flow solver. An automatic dyna­m­i­­c mesh updating proc­e­d­ure is employed using smoothing and l...

Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. Facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. To design a membrane process for olefin-paraffin separation, equilibriu...

By using binary ethanol/water mixtures, the separation performance of two improved commercial pervaporation embranes (PERVAPTM) are presented. Separation performance data are analyzed and compared as a function of operating conditions. The effect of initial feed concentration on the separation performance and the effect of feed concentration on apparent activation energy are presented. For memb...

the idea of separation of powers has been recognized as a model which was first developed and favored by thomas hobbes, john locke, montesquieu and rousseau and was progressively adopted by political systems and constitutional law of various countries. few other countries can be found today that their structure – although seemingly – are not organized on the basis of separation of powers. this ...

Separation anxiety disorder (SAD) is characterized by developmentally inappropriate and excessive anxiety concerning separation from home or those to whom the individual is attached. Literature suggests that child attachment and anxiety symptoms are related. The aim of this study is to discover which symptoms of separation anxiety were associated with avoidant and/or ambivalent attachment. A to...

background: generation of an effective dendritic cell (dc) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. objective: to compare the effects of monocyte separation methods, flask adherence (flask-dc) and magnetic activated cell sorting (macs-dc), on phenotypic and functional characteristics of resultant dcs. methods: dcs from healthy volunteers were generated ...

carvedilol is administered as a racemic mixture of the r(+)- and s(-)-enantiomers, although it was demonstrated that the two enantiomers exhibit different pharmacological effects and stereoselective pharmacokinetics. the aim of this study was the evaluation of several native and derivatized cyclodextrines as chiral selectors for the separation of carvedilol enantiomers. stereoselective interact...

in recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. high-performance liquid chromatography is a very useful method for the direct separation of enantiomers. however, about 30−40 years ago, commercially available chiral stationary phases wer...
