Wear is the progressive loss of the material from the operating surface of machine due to relative motion between surfaces. The successful design of machine elements depends upon essentially on the understanding tribological principles like wear and friction. The lubricating oils are the blood of the machine’s operation, and the service life and economic effectiveness of the machine are relativ...

Soil contamination by used lubricating oil from automobiles is a growing concern in many countries, especially in Asian and African continents. Phytoremediation of this polluted soil with non-edible plant like Jatropha curcas offers an environmental friendly and cost-effective method for remediating the polluted soil. In this study, phytoremediation of soil contaminated with 2.5 and 1% (w/w) wa...

In the present scenario composite materials are extensively used for structural applications in automobile and aerospace industries. Composite material exhibits a high strength to weight ratio, improved hardness, reduced weight and low coefficient of friction. Because of their enhanced tribological properties helps to achieve low manufacturing cost and superior performance. The present research...

Five preparations used as analgesics or lubricants in surgical, obstetrical, gynecological, and investigative procedures were tested for their effect on the isolation of Chlamydia trachomatis. Three lignocaine preparations and a lubricating jelly containing 2% phenol were inhibitory to chlamydiae. In contrast, K-Y lubricating jelly was relatively nontoxic to chlamydiae. Since K-Y jelly also had...

Water vapor jet assisted metal cutting is a pollution-free green cutting technique. This paper has developed a three-dimensional finite element model of water vapor jet assisted cutting in order to understand the influence of its cooling and lubricating effect on cutting process. The cooling effect of water vapor jet is modeled with a convective heat transfer coefficient. A window with the temp...

An experiment was conducted to determine the effect of supplementing diets fed to growing pigs with fat sources differing in their composition of fatty acids on the apparent total tract digestibility (ATTD) of minerals. A diet based on corn, potato protein isolate, and 7% sucrose was formulated. Five additional diets that were similar to the previous diet with the exception that sucrose was rep...

Grease to grease - this is how one might begin to describe the tendency of hydrophobic stretches in protein amino acid sequences to form transmembrane domains. While this simple rule contains a lot of truth, the mechanisms of membrane protein folding, the insertion of hydrophobic protein domains into the lipid bilayer, and the apparent existence of highly polar residues in some proteins in the ...
