This study investigated the effect of rate and type of organic matter, and consecutive application of sodium on secondary particle size distribution. At first, a cropland soil was treated with two organic matter (manure and straw stubble) at different rates of 0%, 1% and 5%, with three types replicates during 4 months. Subsequently, four levels of SAR (0, 1, 10 and 30) were added to the pretrea...
We report on recent progress in the search for dark matter particles with masses from 1 Mev c ^{-2} −2 to Gev . Several candidates this mass range are expected generate measurable electronic-recoil signals direct-detection exp...
I summarize here and discuss the results of presently operating neutrino telescopes in searching for a singnal of dark matter weakly interacting massive particles (WIMPs).
A natural explanation for the smallness of the neutrino mass requires them to be Majorana particles violating lepton number by two units. Since lepton number violation can have several interesting consequences in particle physics and cosmology, it is of utmost importance to find out if there is lepton number violation in nature and what is its magnitude. The neutrinoless double beta decay exper...
Wood burning for residential heating is prevalent in the Rocky Mountain regions of the United States. Studies have shown that wood stoves can be a significant source of PM(2.5) within homes. In this study, the effectiveness of an electrostatic filter portable air purifier was evaluated (1) in a home where a wood stove was the sole heat source and (2) in a home where a wood stove was used as a s...
