The formation of hard surface layer on steel provides a protective coating against wear, thermal loads and corrosion. In the present work a hard composite layer is formed on steel surfaces by preplacement of titanium powder and melted under nitrogen environment. Surface melting was conducted using TIG torch with different energy inputs. The microst

The possibility of forming a TiN dispersed composite layer on steel was studied by preplacement of titanium powder on steel surface and melting under TIG (Tungsten inert gas) torch in a reactive environment. The surface melting of preplaced 1.8 mg/mm2 Ti powder was performed under TIG torch with energy inputs of 324,378 and 432 J/mm in a pure nitro

Charpy impact tests were conducted on carbon reinforced epoxy composites fabricated by hand lay-up method using 0.47, 0.56 and 0.66 carbon fiber volume fractions; tests were conducted at temperatures between -60oC to 60oC. The impact strength was found, in general, to increase when the samples were fractured at temperatures above 0oC and the impact

Cellulose is the main component in plant cell wall and thus the most abundant biopolymer on earth. Endoglucanase is one of the key constituent of a complex multi-enzyme system collectively known as cellulase which degrades cellulose into glucose. Cellulase has been used in various industries such as textile, detergent, food and feed, pulp and paper

Low temperature Thermochemical treatments in fluidized bed furnace involving nitriding, carburizing, and hybrid treating,sequential carburizing-nitriding, have been conducted in the present work with the aim to improve surface properties of AISI 316L. The resulting layer is expanded austenite which is responsible to the higher hardness and better w

Good literature, according to Plato, is one that promotes good morals for its readers. With the advent of theory, however, this notion has suffered a drawback since it was assumed that moral standards involved values deemed universal when they are, it seems, culturally dependent. This presents a dilemma to Muslim students of literature who have a t

Although the philosophy of Muhammad Iqbal is highly original, it reflects a strong and pervading presence of Romanticism. Correspondingly, literary critics have drawn similarities between the English Romantics and Iqbal on a number of thematic concerns, in particular, their appreciation for nature. There is, however, a notable absence of discussion
