The economic viability of agriculture-based enterprises for farm women has been studied along with the constraints and prospects for these enterprises in the Punjab state by selecting the districts of Amritsar and Gurdaspur. Amongst the different enterprises adopted by the women, the four have...

The present study was conducted in Rajpura block of Patiala district in Punjab with a sample of 50 vegetables growers. The total cost of cultivation was estimated at Rs 49563/ha for onion and Rs 34840/ha for cauliflower. The net returns were found higher for onion (Rs 74597/ha) as compared to...

A method based on a real space renormalization group transformation is developed to describe the critical behaviour of a surface interacting linear flexible polymer chain, represented by a self-avoiding walk. It is shown that a lattice model based on a central rule in which the starting point of...

We study the problem of adsorption and collapse transition of a linear polymer chain situated in a fractal container represented by a four-simplex lattice and interacting with a surface-adsorbed linear polymer chain. The adsorbed chain monomers act as pinning sites for the polymer chain. This...
