AbstractE-waste is a new term coined in the market of hazardous substances. It has taken a new bourgeoning route since the boom of Information Technology (IT). The problems regarding the transportation, handling and dispose have to be tackled at the earliest as it might cause detrimental effects on environment. Presently in India there is no distinct and lucid regulation(s) regarding e-waste management. There should one stop solution! In the present paper, some of the Technical and E-Management ...

AbstractIn India, transportation sector is growing fast and the number of vehicles on Indian roads is increasing at a rate more than 7 percent a year. During the period of 50 years from 1951 to 2001, the number of vehicles has increased from 0.3 million to 43 million i.e. an increase of almost 143 times. This has led to overcrowded roads and noise pollution. The transportation sector is one of the major contributors to noise in urban areas, accounting to as much as 55 percent of total noise on t...

Abstract Biofuels represent a possibility for renewable resources conversion, storage and distribution. Today, diesel oil is commercialized only blended with biodiesel, and according to the 30/2003 Directive of the EU, 5.75% of the total fuels used in the transportation sector must be represented by biofuels by the end of 2010. Biodiesel can be produced from vegetable oils, animal fats and used oils. Viscosity is one of the most important characteristics of liquid fuels. The viscosity of liqu...
