Research ArticleOpen accessIn the abstractAssociation of Landscape Metrics to Surface Water Biology in the Savannah River BasinMaliha S. Nash, Deborah J. Chaloud, Susan E. FransonSurface water quality for the Savannah River basin was assessed using water biology and landscape metrics. Two multivariate analyses, partial least square and canonical correlation, were used to describe how the structural variation in landscape metrics may affect surface water biology and to define the key landscape variable(s) that contribute the most to variation in surface water quality. The results … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,292 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy of the Permeability of Foam Conditioned Soils with Laboratory TestsLuca Borio, Daniele PeilaProblem statement: EPB tunneling requires that the excavated soil has a plastic and pulpy behavior to be able to apply a stabilizing pressure to the face, but it should also be impervious to counteract filtration forces that could develop ahead of the face. The evaluation of this parameter in granular soil, before and after conditioning, is therefore of key importance … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,459 accessesView PDF Cite

Research ArticleOpen accessIn the abstractVulnerability and Pollution Risks in the Alluvial Aquifer of Tebessa-MorsottS. Kachi, N. Kherici, N. KachiWe studied the vulnerability and risks of pollution of the alluvial aquifer of Tebessa-Morsott that ranks amongst the major groundwater reservoirs of the region. The method used to asses groundwater vulnerability was the DRASTIC method, based on seven parameters that affect and control the groundwater flow: Depth to groundwater, Impact of the unsaturated zone, net recharge, aquifer media, hydraulic conductivity, … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,812 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Feeding Strategy and Carbohydrate Source on Carbohydrate Utilization by Grass Carp (Ctenopharyngodon idella)L.X. Tian, Y.J. Liu, S.S.O. Hung et al.Problem statement: Feeding strategy is the important factor in aquaculture. Feeding strategy not only could affect the growth performance of grass carp and feed efficiency, but also could affect the quality and environment of water resource. We have proved that glucose was more suitable than starch as the carbohydrate source for grass carp under the restricted feeding frequency. While different … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,991 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordContribution to the Study of the Origin of Salinity in Alluvial Aquifer System in the Ain chabro-Hammamet (North-East ALGERIA)K. Seghir, N. KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,608 accessesView PDF Cite
