This study investigates the effect of biodiesel namely 20MOME (80%diesel+20%mahua oil methyl ester) on a kirloskar, single cylinder, direct injection diesel engine. Performance and emission characteristics like break thermal efficiency, exhaust gas temperature; Carbon monoxide (CO), unburned hydrocarbon (UBHC) and oxides of nitrogen (NOx) emissions were determined for 20MOME and compared with diesel fuel. The results showed that the engine performance under biodiesel blends were similar to that of neat diesel fuel with nearly the same brake thermal efficiency, and slightly higher fuel consumption. The carbon monoxide and hydrocarbon emissions decreased significantly compared to neat diesel fuel whereas the oxides of nitrogen increased.Keywords

In this paper, modeling of a lead acid battery was done by electrical equivalent circuit approach. Model based equivalent circuit approach was used to find the state of charge, terminal voltage, cell temperature and life of the battery at various temperatures. Based on complexity and accuracy, Thevinin’s third order equivalent battery model was simulated using MATLAB Simulink software. The simulation results were validated with the experimental state of charge and terminal voltage values.Keywords

Objectives: The paper deals with the study on analysis of Elliptical Crack for Al7075-T651 for three Dimensional Elliptical crack emanating from hole of the plate. Methods/Statistical Analysis: The impact of Crack shape and location with respect to various tensile loads on stress intensity factor is analysed. The crack in two holes of the plate is differentiated into different cases and they are analyzed for stress intensity factor. The crack case is formed with respect to the location of the through and part through crack in the model. Findings: The stress intensity factor of the crack geometry is attained by Ansys and the results are compared with Polynomial equation derived by displacement Extrapolation method. The paper also analyses the stress intensity factor along with parametric angle and Beta function of through elliptical crack model for various loads. Application/Improvements: The Stress Intensity factor value obtained can be used in finding the fatigue behaviour of materials under various loading conditions and improvements can be made by further improvement in the geometry of the plate.Keywords

The effect of web corrugation and hw/tw ratio on the flexural strength of cold formed steel (CFS) lipped I section is presented in this paper. Totally five specimens were experimented one with flat web and the remaining with trapezoidal corrugation in web. The length of the specimen is kept constant for 3600 mm and hw/tw ratio is varied from 333.33 to 583.33 keeping all other parameters constant. All specimens are experimented under two point loading with simply supported condition. The experimental results are verified with finite element analysis using ANSYS software. Experimental and numerical results are compared with the predicted resistance by North American Specifications (AISI S100-2007) and Australian/Newzealand Standards (AS/NZS: 4600-2005). The experimental result shows that the flexural capacity of the corrugated web is larger than flat web. Within the parametric study the effect of hw/tw ratio on the flexural strength capacity is discussed and presented.

During September through November 2016, some 100 children died due to acute brain disease in Malkangiri district, southern Odisha, India. Most deaths were at first attributed to Japanese encephalitis (JE) due to the following reasons: JE had been reported in Malkangiri district in previous years and diagnostic test for JE was positive in a few children in 2016; JE season is September through November; the vector mosquitoes and amplifying hosts, namely pigs, are prevalent in Malkangiri district. However, a number of cases turned out negative for JE test. Therefore, in the last week of October, the Department of Health, Government of Odisha, constituted a team to investigate the cases of non-JE acute brain disease with high mortality.Full Text
