Contaminated dredged sediments are usually fine texture, and some are low nutrient content or high salinity [, Bioleaching is the application of acidophilic microorganisms capable of Fe/S oxidative metabolism to promote metal dissolution in solid substrates, which is normally conducted as a sediment/soil slurry bioreactor [, S/S technology is used to immobilize contaminants both physically and chemically, which is evidently the most suitable for treatment of metal wastes [, OPC is a hydraulic binder mainly comprised of alite, belite, aluminate, and ferrite [, When OPC blends with supplementary cementitious materials (e.g., fly ash, kiln dust, or silica fume), they would have pozzolanic reactions during hydration. Furthermore, the environmental impact of these technologies should also be continuously monitored and analyzed. and B.W. ; Ogwuegbu, M.O.C. Wen, D.; Fu, R.; Li, Q.

But thinning around homes is not a cure-all -- a hundred-foot wall of flames simply will not lie down at a fuel break or small clearing. Along with the Cubans love for music, there is a love for dance as well. However, the former are more expensive and the latter are time-consuming and have unstable efficiency. The role of planting in the restoration of southern pine ecosystems that are underrepresented on the landscape is simple to the point of being rudimentary--when a seed source of the desired species is absent from a stand, planting is the only way to re-establish the desired species in the stand being restored. Then he weeded and watered and monitored. Yousuf, M.; Mollah, A.; Vempati, R.K.; Lin, T.-C.; Cocke, D.L. ; Karim, A.K. Thomas, G.; Isabelle, C.; Frederic, H.; Catherine, P.; Marie-Anne, B.
