200 Effect of Oxygen Enrichment on Emission Characteristics of a Variable Compression Ratio Diesel Engine Authors: Jitin Yadav, Manu Gupta International Journal for Research in Applied Science and Engineering Techn... 2017/May/21 (17 downloads) Abstract The objective of this research is to explore the effect of oxygen enrichment on emission characteristics for a single cylinder variable compression ratio diesel engine. In this study, a computerised test rig with data acquisition system for a variable compression ratio engine connected with eddy current dynamometer and additional oxygen cylinders to supply the constant oxygen supply by gas regulator in intake air near to intake manifold were used to explore the emission changes by varying compression ratios and oxygen concentrations. Tests were carried out to study the magnitudes of Carbon Dioxides (CO2), Carbon Mono-oxides (CO), Oxides of Nitrogen (NOx) and Hydrocarbons (HC) at two rated Compression Ratios (CR) 16:1 and 17:1 to compare the results with or without oxygen enrichments at the constant rate of 1 litre and 2 litres per minute. However both the techniques increases the NOx emission levels because the enriched air increases the burn and mixing rates of mixture so the temperature increases but also decreases the amount of HC and CO emissions. CO emission decreases because of increase in complete combustion reaction in presence of higher oxygen concentration so the level of CO2 emission increases.

231 Socio Economic Condition of Chandigarh: A Geographical Analysis Authors: Virender Chhachhiya , Ajay Kumar International Journal for Research in Applied Science and Engineering Techn... 2017/May/21 (19 downloads) Abstract In present paper, an attempt has made to analyse the socio-economic correlates (indicators) of Chandigarh. In this study the sex ratio, percentage of female literacy, percentage of working female population, percentage f SC population correlates are used. To draw the socio-economic profile of Chandigarh we use map with the help of Arc GIS 9.3 and correlation with the help of SPSS 16. Moreover, tables used to show the data. The findings are shows that sex ratio, percentage of female literacy and percentage of female working population are positively associated with percentage of SC population in Chandigarh. Keywords: Sex Ratio, Percentage of Female Literacy, Percentage of Working Female Population, Percentage of SC Population
257 Productivity of Scheduled Commercial Banks in India Authors: Ms. Pallavi, Dr. Rajni Saluja International Journal for Research in Applied Science and Engineering Techn... 2017/May/21 (15 downloads) Abstract Banks plays an important role in financing the economic needs of the country. Productivity plays a vital role in economic growth and development in Indian banks. Productivity leads to efficient utilization of human, material and technological resources. The present paper attempts to measure productivity trends of scheduled commercial banks. In this paper productivity is analyzed under three broad parameters of productivity that is branch productivity and employee productivity and financial productivity. The time period of the study is from 2010-11 to 2014-15. The paper concludes that performance of SCBs in term of branch productivity is better on basis of total advances per branch than that of other ratios and employee productivity is better on basis of total deposits per employee than that of other ratios, whereas credit deposit ratio is better than return on assets and return on equity.
