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...

The study has examined the nature and extent of post-harvest losses in vegetable supply chain in the Kumaon division of Uttarakhand. Multistage cluster sampling has been used for selection of 80 vegetable growers, 40 farmers from the hilly region and 40 farmers from the bhabhar region. The...

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...

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...

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...

This study has examined the agribusiness opportunities in medicinal and aromatic plants (MAPs), based on the field level information from the state of Uttarakhand. The financial feasibility of important aromatic plants has been studied. It has been found that the returns are substantially higher...

The private costs and benefits of dry-seeded rice (DSR) were investigated using data from on-station trials at Pantnagar, Uttaranchal, for 2002 and 2003. Results showed that DSR was profitable for farmers, giving net returns of Rs. 13,350 per ha for dry-seeded rice and Rs. 11,592 per ha for...

Farming systems of households in the western Uttar Pradesh have been analyzed based on the primary data collected through a sample of 197 farmers in 2004-05. The sugarcane- based farming system has been found predominant in the study area. Livestock, vegetables, cereals and sugarcane have been...
