The use of biodiesel, the methyl esters of vegetable oils are becoming popular due to their low environmental impact and potential as a green alternative fuel for diesel engine. The aim of this study is to potential use of Pongamia oil methyl ester as a substitute for diesel fuel in diesel engine. Various proportions of Pongamia and Diesel (B25, B50, B75, and B100) are prepared by transesterifi...

The objective of this research work is to evaluate the performance, combustion, and exhaust emissions a variable compression ratio diesel engine utilizing 25% rubber seed biodiesel mixture (B25) blended with 25 ppm 50 alumina nanoparticle running different operating conditions. An ultrasonicator was used make uniform dispersion (Al) nanoparticles in diesel–biodiesel mixture. Biodiesel has physi...

The insulin-like growth factors and hystricomorph insulins have been modelled by interactive computer graphics on the assumption that their sequence homology to insulin implies that they will have a similar tertiary structure. These studies suggest that, although the insulin-related molecules can adopt the insulin fold, they are unlikely to form hexamers and if they form dimers they will be of ...

B-amyloid is the primary protein component of neuritic plaques, which are degenerative foci in brains of patients with Alzheimer's disease (AD). The effects of this naturally occurring B-amyloid on the cells of the central nervous system have not been completely understood. The effect of cytokines such as IL-IB, TNF-a, and IFN-y on astrocytic nitric oxide is well documented; however, the effect...

The present work is focused on determining the performance and emission characteristics biodiesel in DI diesel engine. Experimental investigation of diesel engine was made with 25% (B25), 50% (B50) and 75% (B75) and 100%(B100) blending of Ziziphus jujuba oil with diesel and the results were compared with diesel. Keywords— Ziziphus jujuba, Indian jujube, Edible, Blending, direct injection (DI) d...

In this study, The model Mazda WL diesel engine,4-cylinder, 4 straight-line cylinder with biodiesel blends ratio of 0%, 15%, 20%, 25%, 30% derived from rubber seed oil and DO has been simulated on ANSYS FLUENT software to analyze fuel consumption characteristics. Experimental engine using (DO) (B15, B20, B25, B30) for a installed 2500 Ford Ranger cars. simulation results show that the average i...

The finitude and environmental impact of petroleum fuels have led to the search alternative biodiesel has proven be an fuel petro-diesel with less impact. Engine performance exhaust emissions Sandbox Methyl Ester (SBME) were evaluated. Pure SBME (B100) was blended diesel at 5, 10, 15, 20, 25 50% volume designated B5, B10, B15, B20, B25 B50 respectively. used as a reference fuel. blends (B100-B5...

Photoelectron spectroscopy and ab initio calculations are used to investigate the structures and chemical bonding of the B25(-) cluster. Global minimum searches reveal a dense potential energy landscape with 13 quasi-planar structures within 10 kcal/mol at the CCSD(T)/6-311+G(d) level of theory. Three quasi-planar isomers (I, II, and III) are lowest in energy and nearly degenerate at the CCSD(T...
