The unsteady natural convection boundary layer (NCBL) on a vertical wall heated by time-varying flux in initially quiescent homogeneous fluid with small Prandtl number (Pr) was studied. Scalings for the parameters typifying NCBL behavior, including plate temperature, maximum velocity, thermal boundary-layer thickness, and velocity at different development stages, time transition from start-up s...

This study aimed at studying the effect of yogic package (YP) with some selected pranayama, cleansing practices and meditation on pain intensity, inflammation, stiffness, pulse rate (PR), blood pressure (BP), lymphocyte count (LC), C-reactive protein (CRP) and serum uric acid (UA) level among subjects of rheumatoid arthritis (RA). Randomized control group design was employed to generate pre and...

We present a detailed temperature-dependence study of dielectric, birefringent, conductive, and photorefractive (PR) properties of high-performance low-molecular weight organic glasses that contain 2-dicyanomethylene-3-cyano-2,5-dihydrofuran (DCDHF) derivatives. DCDHF organic glasses sensitized with C60 exhibit high two-beam coupling gain coefficients in the red-wavelength region. However, in t...

The variational multiscale (VMS) formulation is used to develop residual-based VMS large eddy simulation (LES) models for Rayleigh-Bénard convection. resulting model a mixed that incorporates the and an viscosity model. Wall-Adapting Local Eddy-viscosity (WALE) as in this work. new LES were implemented finite element code Drekar. Simulations are performed using continuous, piecewise linear elem...

Abstr act . Tournament select ion is a useful and rob ust select ion mechanism commonly used by genet ic algorithms (GAs). The selecti on pr essure of to urnament select ion direc tly varies wit h the tournam en t size-the more compe t it ors , t he higher the resulting select ion pr essur e. This pap er develops a model, based on order stat ist ics, that can be used to quantita tively predict ...

In coronary artery bypass grafting (CABG), vasospasm of arterial conduits is a significant clinical problem. Unlike the internal mammary artery, the radial artery (RA) is stored in theatre before grafting. Storage induces temperature shocks upon the RA, both following the initial isolation and upon the return of the graft to body temperature. We have studied the effect of temperature changes in...

An experimental investigation of the melting process in the vicinity of a heated vertical wall in a rectangular enclosure is presented in this work. A ̄at-plate heat pipe was used to provide a uniform temperature source. The liquid ̄ow patterns during the melting process were captured and the instantaneous marching of the liquid±solid interface was presented. In addition, the temperature distri...

Rayleigh number (<i>Ra</i>) dependence in Rayleigh-Bénard (RB) convection has been studied by many investigators, but the reported power-law scaling expressions are different these researches. Previous studies have found that when <i>Ra</i> reaches a critical value, flow patterns change and transition appears of <i>Nu</i>(<i>Ra</i>) (where <i&g...
