Electro Less Duplex Nickel Coating and Tribological Characterization Under Elevated Temperature
Abstract: Electroless Ni-P (EN) coatings had previously demonstrated their ability to improve the tribological properties of the underlying substantial. This is due to its high hardness, fatigue strength, and chemical resistance. Nevertheless, the EN coverings' effectiveness at high temperatures, as well as their heat resistance, have yet to be evaluated. The current work investigates the tribological properties, namely friction and wear, of EN coatings at increased temperatures (100 ºC, 200 ºC, …

SYMMETRY AND ASYMMETRY MODEL FOR THERMAL CONDUCTIVITY IN POROUS MEDIA
Abstract: This paper focuses on determining thermal conductivity in porous media using symmetry and asymmetry models. Since porous media are not uniform and homogeneous in most of the cases, anisotropy must be taken into account, what derives in the application of an asymmetry model as thermal gradients are not equal in all directions. The paper demonstrates that, under certain conditions, isotropic conditions, therefore, symmetry model can be applied to non-homogeneous or …

An Experimental Study of Spherical Agglomeration of Benzoic acid And Influence of Process Parameters
Abstract: Through the process of drowning-out crystallisation in three partly miscible solvent mixtures, sphere aggregates of benzoic crystal have been successfully created. The mixture of benzoic acid, isopropyl alcohol, and bridging liquid is supplied to an agitated crystallizer with water acting as the anti-solvent. When a substance crystallises, little crystals are formed, and the bridging liquid causes the crystals to group together. Different solvents are utilised because benzoic acid crystals wettably …

Unani Concept of Tadarrun-e-Revi (Pulmonary Tuberculosis): A Review
Abstract: In Unani system of medicine, pulmonary tuberculosis is known as Tadarrun-e-Revi. Unani physicians also called it Diq or humma-e-diq or tap-e-diq. The ulcer which is formed in lungs due to tuberculosis is called sil. The word Diq means thinness or debility. In Diq, the increased temperature of body destroys the body fluid, because of which, the body of affected person becomes thin and dry. Hence the disease is called Humma-e-diq. …
