Obesity (Siman-E-Mufrat) in Greeco-Arabic Perspective: A Review
Abstract: Tibb-e-Unani has been rendering services to the mankind for thousands of years. This healing art is one of the oldest and well organized systems of medicine. The Greeks were the first to recognize Siman-e-mufrat (obesity) as a medical disorder. It is evident that Buqrat (460–377 BC) was first who described obesity (siman-e-mufrat) in his famous book Fusool-e-Buqrat. Buqrat understood that siman-e-mufrat leads to infertility and early death. He was also …

Numerical Simulation of Entrained-flow Coal Gasification: A Study on Particles History
Abstract: Normal 0 false false false MicrosoftInternetExplorer4 Studies of coal particle history during coal gasification inside the gasifier are very limited. A comprehensive 3D numerical simulation of entrained-flow coal gasification is conducted. The Eulerian-Lagrangian approach is applied to solve the Navier-Stokes equations and the particle dynamics. The finite rate/eddy dissipation model is used to calculate the rate of gasgas phase reactions, whereas only finite rates are used for solid-gas phase reactions. …

Thermo-hydraulic Performance of Annular-Finned Double-Pipe Heat Exchanger: Numerical and Experimental Investigation of Metallic and Polymer Composite Tube Wall Materials
Abstract: Double-pipe heat exchangers are central to the process industries — dependable, easily maintained, and straightforward to fabricate. Their conventional form relies on metallic tube materials, most often copper or stainless steel. Both metals conduct heat well, but they are dense, prone to corrosion in aggressive service environments, and increasingly at odds with the light-weighting goals that drive modern system design. Fibre-reinforced polymer composites, epoxy-based materials, and thermally enhanced thermoplastics such …
