Dielectric properties of silver/SiO<Subscript>2</Subscript> nanocomposite thin films grown by high-pressure d.c. sputtering technique were studied by spectroscopic ellipsometry (300-800 nm). The dielectric behavior of the nanocomposite thin films largely depended on the particle size, its number density and the...</subscript>

Cavity formation is an important phenomenon in the underground coal gasification (UCG) process. In the early stages of cavity formation, only the combustion reaction is performed in order to stabilize the temperature field. In the present work, we study the formation of the combustion cavity and...

Systematic laboratory scale experiments on coal blocks can provide significant insight into the underground coal gasification (UCG) process. Our earlier work has demonstrated the various features of the early UCG cavity shape and rate of growth through lab-scale experiments on coal combustion,...

The costs and returns structure has been reported for the production of major off-season vegetables, viz. tomato, cabbage cauliflower and peas in two vegetable-dominated developmental blocks of the district Kullu. Primary data have been collected through survey method for the agricultural year...

The study has assessed the impact of extension programmes on the adoption level of improved technologies in agriculture and animal husbandry in the Kullu district of Himachal Pradesh for the agricultural year 2002-03. A significant difference has been observed in the knowledge and adoption...

The study has been undertaken with the objectives of finding the extent of land degradation and its determinants in the mountainous regions of Himachal Pradesh by dividing the state into four zones. Multistage random sampling technique has been adopted to select the sample farmers from each...
