There is an increasing interest in many countries to search for suitable alternative fuels that are environment friendly. Although straight vegetable oils can be used in diesel engines, their high viscosities, low volatilities and poor cold flow properties have led to the investigation of various derivatives. Biodiesel is a fatty acid alkyl ester, which can be derived from any vegetable oil by transesterification. Biodiesel is a renewable, biodegradable and non-toxic fuel. In this study, Brassica oil (Brassica juncea seed oil) was transesterified with methanol using sodium hydroxide as catalyst to obtain brassica oil methyl ester (BOME). This biodiesel was tested in a single cylinder 4 stroke diesel engine (Kirloskar) to evaluate the performance characteristics. © 2006-2012 Asian Research Publishing Network (ARPN). Source

A study has been carried out to investigate the tensile properties of alkali treated woven jute natural fiber and woven glass fiber reinforced Hybrid Composites Bolted Joint (TCBJ) and Untreated Hybrid Composite Bolted Joint (UTCBJ). Effect of stacking sequence and fiber treatment on tensile strength, hardness and impact strength of alkali treated woven jute natural fiber and woven glass fiber reinforced hybrid composites and Untreated Hybrid Composite has been investigated experimentally. It has been observed that the tensile properties increase with respect to jute fiber content. The results indicated that the properties of jute composites can be considerably improved by incorporation of glass fibre as extreme glass plies. The layer sequence has greater effect on hardness and Impact Strength. © 2006-2012 Asian Research Publishing Network (ARPN). Source

This paper presents the experimental investigations performed on concrete specimens when subjected to curing in aggressive environment such as in different acid and base media namely HNO3, HCl, H2SO4, NH4CL, MgCl2, and NaCl. The deterioration of plain cement concrete specimens and corrosion rate of steel in reinforced concrete specimens are discussed by estimating various constituents such as leached sulphate, chloride, pH and reduction in strength periodically. The corrosion behavior of steel embedded in concrete has been studied by electrochemical techniques such as impedance, and linear polarization methods and the corrosion rate for the steel bars were found by gravimetric weight loss method. From the results it was observed that in the curing medium of HNO3 the specimens were found to deteriorate more and the corrosion rate was also found to be more. Among the specimens cured in base medium deterioration was found to be more in MgCl2 and corrosion was steel was observed as a maximum in NaCl. The aim of this project is to find the quantitative analysis for corrosion. © Research India Publications. Source

In the present communication an effective parametric analysis on the mechanical properties (tensile and flexural strength) of bagasse fiber-reinforced vinyl ester (BFRVE) composites were conducted, and then the fabrication process parameters were optimized by using Taguchi and analysis of variance techniques. Composites plates were fabricated by Taguchi's L18 experimental design as the function of process parameters such as fiber length, fiber content, fiber diameter, sodium hydroxide concentration and sodium hydroxide treatment duration. The optimum process parameters to obtain the maximum strength values were identified using signal-to-noise ratio calculations. Then, the results were analyzed to know the percentage contribution of each fabrication process parameter on the tensile and the flexural strength using analysis of variance. A multivariable non-linear regression model was developed to predict the strength values and compared with experimental strength values. The developed models were validated by 10 additional experimental results using the mean absolute percentage error (MAPE). The results reveal that the fiber content (40 wt%) is the most significant factor influencing the tensile and flexural strength. An acceptable level of mean absolute percentage errors (8.57% for tensile strength and 9.13% for flexural strength) was obtained in both cases. Finally, the results indicate that this model can be used efficiently for prediction of tensile and flexural strength of BFRVE composites without any further experiments. © The Author(s) 2015.
