Research ArticleOpen accessIn the abstractTreatment of Remazol Brilliant Blue Dye Effluent by Advanced Photo Oxidation Process in TiO2/UV and H2O2/UV reactorsM. Verma, A.E. GhalyAdvanced oxidation processes involving TiO2/UV and H2O2/UV were evaluated for their potential use in decolorization of textile dye effluents. A coil photo reactor, consisting of UV radiation source and a spiral coil coated with TiO2, was used to treat synthetic effluent of Remazol Brilliant Blue dye. The TiO2 coating was performed using the sol-gel technique. The effects of UV radiation, … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodiesel Fuel Production from Algae as Renewable EnergyA.B.M. Sharif Hossain, Aishah Salleh, Amru Nasrulhaq Boyce et al.Biodiesel is biodegradable, less CO2 and NOx emissions. Continuous use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment. Renewable, carbon neutral, transport fuels are necessary for environmental and economic sustainability. Algae have emerged as one of the most promising … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 32,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Water Resources Management Improving Langat Basin Ecosystem HealthMazlin B. Mokhtar, Mohammad Fawzi Al Ajlouni, Rahma ElfitrieThe ecosystem provides us with all the goods and services that form the base of our economic, social cultural and spiritual life. Good scientific information will be required for managing the environment by using the Ecosystem approach. The groundwater is considered as a possible supplementary of alternative water source, and some factories already started shifting their water source from surface … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,053 accessesView PDFCite

Sia SuThe study assessed and compared the groundwater quality of 14 selected wells continuously used in the with (Payatas) and without dumpsite (Holy Spirit) areas at the Payatas estate, Philippines. Water quality monitoring and analyses of the bio-physico-chemical variables (pH, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), total coliform, conductivity, salinity, nitrate-nitrogen, sulfate, color, total chromium, total lead and total … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydropower System Management Considering the Minimum OutflowM. L. Arganis, R. DomínguezThis paper deals with the operating rules of the Grijalva River hydropower serial system obtained by means of stochastic dynamic programming and its subsequent simulation using historical records and synthetic series. Penalties in spills and deficit were considered in optimum policies. During simulation several restrictions were added to the original problem, particularly to ensure minimum outflow so as to guarantee … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,540 accessesView PDFCite

This cross-sectional study was performed on 493 randomly selected medical students and hospital … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstablishment and Evaluation of the Vegetative Community in A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC.C. Galbrand, A.M. Snow, A.E. Ghaly, R. CôtéA surface flow constructed wetland, designed to curve in a kidney shape in order to increase the length to width ratio to 5:1 was used to treat runoff from an industrial park. A natural wetland system located approximately 200 m downstream of the constructed wetland was selected to act as the vegetative community model for the constructed wetland. The selected … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Use of Rice Bran Compost for Eco-friendly Weed Control in Organic Farming SystemsM.A.I. Khan, K. Ueno, S. Horimoto et al.Rice bran compost (RC) was evaluated under greenhouse and field conditions for eco-friendly weed control of vegetable crops in organic farming systems. RC was applied 7 days before spinach seed sowing, at the rate of 0% (control), 10%, 20% and 30% of soil (v/v) in the greenhouse and 2 kg m-2 under field conditions. RC significantly controlled the number and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,927 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Determination of Buffering Capacity of Some Ruminant's Feedstuffs and their Cumulative Effects on TMR RationA. MoharreryTwo experiments have been conducted in order to investigate the buffering capacity of some ruminant's feedstuffs and their additivity to calculate ration buffering capacity as a tools for feed formulation. The first experiment was performed with different types (65 samples) of feedstuffs to determine the Buffering Capacity (BC) and Buffer Value Index (BVI). For investigation of cumulative effects of buffering … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,434 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecovery in Distributed Systems from Transient and Permanent FaultsM. Aliouat, Z. AliouatThe recovery mechanism from transient fault in distributed systems has been intensively studied in the past, but to our best knowledge, none of these studies has been devoted to cope together with transient and permanent hard faults. Our study devoted to recovery processes in a distributed environment in case of hard faults like transient or permanent. The recovery mechanism we … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,854 accessesView PDFCite
