In 2009, the average lifespan of a Japanese male was 79.6 years and that of a female was 86.4 years. This was the highest in the world; about 60 years ago, the average in the Japanese population was approximately 50 years. It is thus apparent that Japan has rapidly been becoming an aged society. In 2010 there were 29,440,000 individuals age 65 or older; this number will increase steadily, and i...

Bio-diesel the mono-alkyl esters of vegetable oils can serve as sustainable energy resources alternative to depleting fossil fuels and has gained more importance due to its clean environmental benefits, renewability and biodegradability. The proposed paper highlights the results of experimental investigations on the scope of utilizing biodiesel manufactured from Polanga and Jatropha oils as an ...

Physiological changes taking place on the locomotive apparatus as a result of aging, such as muscular mass loss, body balance loss, reduced bone mass and osteoarthrosis cause limitations to the daily activities of elderly people, compromising their quality of life and making them weaker and dependent. Aged people who regularly practice physical activities have a higher level of functional indep...

The subject of these studies is the assessment fuel and energy efficiency using locomotives diesel traction in various conditions for organizing operational activities railways with third type track profile. purpose study: to substantiate logistic parameters main indicators transport logistics freight trains transportation work three-section (train) 3 TE 10 M series on real hilly-mountainous se...

Base on the characteristics of high-speed and heavy-load locomotive traction gear, a pre-grinding hob was designed which increased the thickness of the dangerous tooth root section as much as possible. The deformation and stress of the traction gears were calculated through the parameterized model established by finite element method. The tooth profile modification was implemented considering t...

This paper presents an experimental investigation on a four-stroke single cylinder diesel engine fuelled with the blends of Mahua oil methyl ester (MOME) and diesel. The performance emission, energy, and exergy analysis has been carried out in B20 (mixture of 80% diesel by volume with 20% MOME). From energy analysis, it was observed that the fuel energy input as well as energy carried away by e...
