Ericulture as a Remedy of Rural Poverty in Assam: A Micro Level Study in Barpeta District

Ericulture i.e., rearing of eri cocoon and spinning as well as weaving of endi clothes has been an integral part of the rural economic activities especially of the rural women in Assam. Though both male and female folk of all sections of rural population have been engaged in different sericulture activities, tribal women have been predominant in the rearing and weaving of eri raw silk and endi textiles, who in addition to their daily household activities use their leisure time and with the help of their traditionally inherited knowledge produce useful but comparatively cheaper endi clothes. The activities not only help to increase their household income but also help many of them to come out of the acute poverty. Moreover, these women become economically and thus socially more empowered. An attempt is made in this paper to throw some light on the role of ericulture and endi-entrepreneurship in the generation of income, employment and removal of poverty in Assam.Ericulture, Poverty eradication, Rural entrepreneurship

Effect of an inhomogeneous external magnetic field on a quantum dot quantum computer

We calculate the effect of an inhomogeneous magnetic field, which is invariably present in an experimental environment, on the exchange energy of a double quantum dot artificial molecule, projected to be used as a 2-qubit quantum gate in the proposed quantum dot quantum computer. We use two different theoretical methods to calculate the Hilbert space structure in the presence of the inhomogeneous field: the Heitler-London method which is carried out analytically and the molecular orbital method which is done computationally. Within these approximations we show that the exchange energy J changes slowly when the coupled dots are subject to a magnetic field with a wide range of inhomogeneity, suggesting swap operations can be performed in such an environment as long as quantum error correction is applied to account for the Zeeman term. We also point out the quantum interference nature of this slow variation in exchange.Comment: 12 pages, 4 figures embedded in tex
