and second the dynamics of this folding process can result in enhanced binding kinetics. several groups have hypothesized the acceleration of binding kinetics is due to induced folding where a fly casting effect has been shown to break the diffusion limited rate of binding.
uranium mining facilities produce tailings that generally are disposed of in near surface impoundments close to the mine. these tailings pose serious environmental and health risks in the form of randon emission windblown dust dispersal and leaching of contaminants including heavy metals and
mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. the effects of this damage can continue years after a mine has shut down including the addition to greenhouse gasses death of flora and fauna and erosion of land and habitat.
