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 · 32,073 accessesView PDFCite
Research ArticleOpen accessIn the abstractTraditional Aquaculture Practice at East Calcutta Wetland: The Safety AssessmentS. Raychaudhuri, M. Mishra, S. Salodkar et al.The current study is on East Calcutta Wetland (ECW) which is a model for multi-use resource recovery system with activities like pisciculture and agriculture. The entire city's soluble waste is disposed into the raw sewage canals which finally drains into the shallow, flat bottom fish ponds called Bheri. These sewage fed fisheries act simultaneously for the purification process like removal … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,442 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Barley for the Purification of Aquaculture Wastewater in a Hydroponics SystemA.M. Snow, A.E. GhalyBarley was examined for its ability to remove nutrients from aquaculture wastewater. The effects of seed sterilization using ethanol and bleach and seed density on germination and plant growth were investigated. Surface sterilization of barley seeds had a negative impact on germination. Increasing the ethanol concentration and/or the bleach concentration reduced the germination percentage. Barley seeds were first germinated in … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,489 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,111 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 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of 2D Multi Electrodes Resistivity Imagining for Sinkholes Hazard Assessment along the Eastern Part of the Dead Sea, JordanAbdallah S. Al-Zoubi, Abd El-Rahman A. Abueladas, Rami I. Al-Rzouq et al.Sinkholes and subsidence are natural phenomena can be occurred in shallow geology sediments at different regions in the world. Sinkholes assessment is one of the most difficult near subsurface investigations. Geophysical prospecting is appropriate method to determine environmental and geotechnical problems. 2D multi electrodes resistivity imagining with Wenner-Schulmberge array was conducted within active sinkholes area. The objective of the survey … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Nitrate Contamination Risk Assessment: A Comparison of Parametric Systems and Simulation ModellingDario Sacco, Marco Offi, Marina De Maio, Carlo GrignaniGroundwater nitrate contamination is a source of rising concern that has been faced through the introduction of several regulations in different countries. However the methodologies used in the definition of Nitrate Vulnerable Zones are not included in the regulations. The aim of this work was to compare different methodologies, used to asses groundwater nitrate contamination risks, based on parametric systems … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,127 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Mirex Concentrations along the Southern Shorelines of the Great Lakes, USADennis A. Apeti, Gunnar G. lauensteinMirex is a persistent and toxic polychlorinated pesticide that has compromised environmental quality in the Great Lakes region since the 1960s. As a bioaccumulative and carcinogenic compound, mirex at its current levels in Lake Ontario is a concern because of the potential for trophic level transfer and biomagnification in top predators. As a part of the NOAA’s National Status and … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Administration of Alpha-Melanocyte Stimulating Hormone (α-MSH) on Some Hematological Values of Alloxan-induced Diabetic RatsKamal M.S. MansiThis study was designed to evaluate the role of alpha- melanocyte stimulating hormone (α-MSH) on heart rate and some hematological values in alloxan induced diabetic rats. 40 male white rats were divided into four experimental groups: control, diabetic, α-MSH-treated and α-MSH-treated diabetic. At the end of the experimental period (3weeks), animals in all four groups were fasted for 12 hrs … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 1 · 31 Mar 2006 · 7,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractContribution of Advective and Non-advective Heat Fluxes to the Heat Budget of a Shallow LagoonRodríguez-Rodríguez MiguelThe heat budget in a shallow lagoon has been established from field measurements at a bihourly scale. Information on the main advective and non-advective heat fluxes were collected during year 2003 at Nueva lagoon (Almería, Southern Spain). Heat storage data was obtained from a thermistor chain located in the deepest part of the lagoon and meteorological information was acquired using … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,495 accessesView PDFCite
