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 abstractTiO2 Nanoparticles-Coated Polypropylene Copolymer as Photocatalyst on Methylene Blue Photodegradation under Solar ExposureHasniah Aliah, Mahardika Prasetya Aji, Masturi et al.Problem statement: Pollutions of water bodies by dye wastes from textile industries and other sources have become critical consideration. A photocatalytic technique using semiconductor materials such as Titanium Dioxide (TiO2) activated by lights has been considered as one economical method to solve this problem. Approach: We attached titanium dioxide on the surface of polymer grains as photocatalyc agents using a … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 29 May 2012 · 7,859 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Fuel Properties on Exhaust Emissions during Warm-Up ProcessRosli Abu Bakar, Beny CahyonoProblem statement: Increasing air pollutions the big problem form internal combustion engines. Several attempts have been done to get a cleaner combustion process, one of which is the use of fuel ethanol in gasoline engines. Approach: The addition of ethanol in fuel will be change fuel properties. Results: To know the effect of fuel properties on engine performance and emissions … …Energy Research Journal, Vol. 2, Issue 1 · 23 Jan 2012 · 7,278 accessesView PDF Cite
