This article presents experiments on the determination of the length scales of magnetic correlation in ε-Co nanoparticle assemblies using SANS (small angle neutron scattering). In this experiment a 0.5 nm neutron beam was passed through a sealed sample containing a dense assembly of the nanoparticles, and the scattered intensity was collected with two-dimensional detector. Data were collected with...
The rural population of the Himalayas has been using firewood as the only source of energy for generations. Increasing population coupled with decreasing forest resources have led to strict environmental protection laws in the area. This paper analyses the fuelwood consumption pattern for households along an altitudinal gradient in Garhwal Himalaya, Uttaranchal. Firewood consumption was 2.80, 2.00,...
Excessive use of firewood, as a primary source of energy for domestic purposes, is leading to severe deforestation in the northeastern Himalayan region. Firewood consumption pattern of three tribal communities of Meghalaya, India- Garo, Khasi and Jaintia was studied under varying ecological, socio-economic and socio-cultural conditions. Fuelwood consumption was highest to Khasi community (5.81kg/capita/day),...
