Characteristic and composition of Jatropha curcas oil seed from Malaysia and its potential as biodiesel feedstock feedstock

Abstract: Due the environmental concern and limited resources of petroleum oil has increase the demand of biodiesel. One way of reducing the biodiesel production costs is to use the less expensive feedstock containing fatty acids such as inedible oils, animal fats, waste food oil and by products of the refining vegetables oils The fact that Jatropha oil can not be used for nutritional purposes without detoxification makes its use as energy/fuel source very attractive. The lipid fraction of Jatropha oil seed were extracted and analyzed for their chemical and physical properties such as acid value, percentage free fatty acids (% FFA), iodine value, peroxide value and saponification value as well as viscosity, and density. The fatty acid and triacylglycerol (TAGs) composition of the extracted lipid was revealed using the gas chromatography (GC) and high pressure liquid chromatography (HPLC) method. Both oleic acid (44.7%) and linoleic acid (32.8%) were detected as the dominant fatty acids while palmitic acid and stearic acid were the saturated fatty acids found in the Jatropha oil. Characteristic and Composition of Jatropha Curcas Oil Seed from Malaysia and its Potential as Biodiesel Feedstock Feedstock 397 OLL (22.94%) and OOL (17.9%) was detected as major triacylglycerol composition in the jatropha oil. The oil extracts exhibited good physicochemical properties and could be useful as biodiesel feedstock and industrial application.

Numerical solution of the boundary layer flow over an exponentially stretching sheet with thermal radiation

Abstract: In this paper, the problem of steady laminar two-dimensional boundary layer flow and heat transfer of an incompressible viscous fluid with a presence of thermal radiation over an exponentially stretching sheet is investigated numerically. The governing boundary layer equations are reduced into ordinary differential equations by a similarity transformation. The transformed equations are solved numerically using an implicit finitedifference scheme known as the Keller-box method. The numerical solutions for the wall skin friction coefficient, the heat transfer coefficient, and the velocity and temperature profiles are computed, analyzed and discussed.

Hepatoprotective Activity of Methanol Extract of Some Medicinal Plants Against Carbon Tetrachloride Induced Hepatotoxicity in Albino Rats

Abstract: 2 Abstract: The methanol extracts of plant materials of some plants like Casuarina equisetifolia, Cajanus cajan, Glycosmis pentaphylla, Bixa orellana, Argemone mexicana, Physalis minima, Caesalpinia bonduc, belonging to the different family were studied for hepatoprotective activity against Swiss albino rats with liver damage induced by carbon tetrachloride(CCl ). It was found that the methanol extract of B. orellana, C. cajan, 4 G.pentaphylla and C. equisetifolia at a dose of 500 mg/kg body weight exhibited moderate protective effect by lowering the serum levels of alanine aminotransferase(ALT) or Serum Glutamate Pyruvate Transaminase (SGPT), aspartate aminotransferase (AST)or Serum Glutamate Oxaloacetate Transaminase (SGOT) and cholesterol to a significant extent. Other methanol extracts of A. mexicana, P. minima and C. bonduc had no effect of lowering blood serum level rather than produced toxicity at the above specified dose. The highest activity of observed for methanol extract of B. orellana at a dose of 500 mg/kg body weight (b.wt.) and the reduction of serum level of ALT, AST and cholesterol were 52.08%, 57.37% and 52.90% respectively. The hepatoprotective activity was also supported by histopathological studies of liver tissue. Since results of biochemical studies of blood samples of carbon tetrachloride treated rats showed significant increase in the levels of serum enzyme activities, reflecting the liver injury caused by CCl and blood samples from the animals 4 treated with the methanol extracts of B. orellana, C. cajan, G.pentaphylla and C. equisetifolia showed significant decrease in the levels of serum markers, indicating the protection of hepatic cells, the extracts of four above plants could afford significant dose-dependent protection against CCl induced hepatocellular injury. 4

Performance comparison of AODV, DSDV and I-DSDV routing protocols in mobile ad hoc networks.

Abstract: Ad hoc networks are characterized by a lack of infrastructure, and by a random and quickly changing network topology; thus the need for a robust dynamic routing protocol that can accommodate such an environment To improve the packet delivery ratio of Destination Sequenced Distance Vector (DSDV) routing protocol in mobile ad hoc networks with high mobility, a message exchange scheme for its invalid route reconstruction is being used Three protocols AODV, DSDV and I-DSDV were simulated using NS-2 package and were compared in terms of packet delivery ratio, end to end delay and routing overhead in different environment; varying number of nodes, speed and pause time Simulation results show that I-DSDV compared with DSDV, it reduces the number of dropped data packets with little increased overhead at higher rates of node mobility but still can’t compete with AODV in higher node speed and number of node

The extent of disclosure in annual reports of banking companies: The case of India

Abstract: This study is an empirical investigation of the extent of both mandatory and voluntary disclosure by listed banking companies in India. It also reports the results of the association between company-specific attributes and total disclosure, i.e., mandatory and voluntary, of the sample companies. A total of 184 items were selected of which 101 and 81 were mandatory and voluntary respectively. The study revealed that in disclosing mandatory items, the average score is 88, whilst the average score for voluntary disclosure is 25. The findings also indicate that size, profitability, board composition, and market discipline variables are significant, and other variables such as age, complexity of business and asset-in-place are insignificant in explaining the level of disclosure. Results also indicate that Indian banks are very compliant with the rules regarding mandatory disclosure. In contrast, they are far behind in disclosing voluntary items. This paper has contributed to the academic literature, showing that the existence of a close monitoring system by regulatory authorities brings the potential for high compliance regarding disclosure and transparency, at least in mandatory cases. This study would be a good example for other developing countries, wanting to learn how Indian banks achieved this high level of compliance in mandatory disclosure.
