Natural changes in climate due to internal as well as external factors, like anthropogenic emission, fossil fuel combustion, transportation and heating which cause CO2 emissions is one of the major issues which causes global warming (increasing concentrations of greenhouse gases). The production...

This paper applies data envelopment analysis (DEA) based Malmquist productivity index (MPI) approach to examine the total factor productivity (TFP) growth and its components of 50 private sector hospitals of India for the period 2004-2005 to 2009-2010. The study finds that on average, the TFP...

The process of liberalization and globalization of Indian economy has brought new opportunities and challenges in all areas of human endeavor including education. Educational institutions have to adopt new strategies to make best use of the opportunities and counter the challenges. One of these...

Drying kinetics of materials may be described completely using their transport properties together with those of the drying medium. In the case of food drying, the drying rate constant ‘k’ was used instead of transport properties. The drying rate constant combines all the transport...

The recent increased number of black outs in the power system has been largely due to growing competition and deregulation among the power industry. Power systems are complex nonlinear systems and often exhibit low frequency electro-mechanical oscillations due to insufficient damping caused by...

The world is confronted with the twin crises of fossil fuel depletion and environmental degradation. The indiscriminate extraction and consumption of fossil fuels have led to a reduction in petroleum reserves. Petroleum based fuels are obtained from limited reserves. These finite reserves are...

Biogas digesters have captured many imaginations because they can turn organic wastes from our farms, factories and cities into a valuable source of renewable energy. In addition, the potential of this technology to reduce odors and other environmental concerns of animal feedlots has resulted in...

A naturally aspirated multi cylinder diesel genset (DG) was operated successfully with mixed fuels (fossil-diesel (FD), refined rice bran oil (RRBO) and producer gas from a wood gasifier). Performance of DG set in FD, dual fuel mode (FD+RRBO in different proportion and FD+producer gas) and mixed...

Thermodynamic analysis for evaluating and improving coal gasification process efficiency requires estimation of enthalpy, entropy, and availability transformations in various process steps. A compilation of procedures and data relevant to coal gasification processes is presented for calculating...
