Rough tilted pad slider bearing lubricated with a magnetic fluid
Shukla, S. D., and G. M. Deheri

The performance of a transversely rough tilted pad slider bearing was analyzed in the presence of a magnetic fluid lubricant. A mathematical model based on stochastic averaging process was developed. The expressions for non dimensional pressure, load carrying capacity and friction were derived. The computed results made it clear that the bearing working with magnetic fluid as a lubricant had a better performance than that of an identical bearing working with a conventional lubricant. In...

Co-operatives: A few words
Bhola Nath Ghosh

The term co-operation is derived from the Latin word co-operari, where the word co means ‘with’ and operari means ‘to work’. Thus, co-operation means working together. So those who want to work together with some common economic objective can form a society which is termed as “co-operative society”. It is a voluntary association of persons who work together to promote their economic interest. It works on the principle of self-help as well as mutual help. The main objective is to provide...

Production of biodiesel from waste deep frying oils as a renewable Energy source
Jong Yang, Abu Saleh Ahmed and Sinin Hamdan

Biodiesel is a non-petroleum based fuel derived from vegetable oils or animal fats. Biodiesel has attracted huge attraction worldwide due to its renewability, biodegradability, and its better gas emission. The process of biodiesel production which converts vegetable oils and fats to fatty acid methyl ester using a short chain alcohol and catalyst called transesterification. A maximum of 92% biodiesel conversion obtained by using 1:4 oil/methanol ratio and catalyzed by KOH. Brake horse power...
