Research ArticleOpen accessIn the abstractBioaugmentative Approaches for Dairy Wastewater TreatmentIrina Schneider, Yana TopalovaProblem statement: The achievement of a good ecological status of water receivers after discharge of waste or partially treated water from dairy industry requires harmonic interaction between water treatment technology and self-purification processes. Approach: The present research included two modules. First: an anaerobic treatment process for dairy wastewater in broadly spread sequencing batch bioreactor with fixed biomass was studied. As … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 8,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Potential of Extended Aeration System for Sago Effluent TreatmentWahi Abd Rashid, Hamdan Musa, Wong Sing King, Kopli BujangProblem statement: Sago effluent contains large amount of organic material which has a potential to cause water pollution. In order to reduce this problem, an experiment was conducted to remove organic material from sago effluent using lab scale of Extended Aeration (EA) system. Approach: The EA system consisted of the combination of physical and biological treatment unit. For Physical Treatment … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,346 accessesView PDFCite
Research ArticleOpen accessIn the abstractMan in Outer Space Without a Special Space SuitAlexander BolonkinProblem statement: Many people dreamed about a living human in space without the encumbrance of a complex space suit. Unfortunately no scientific research and inventions: How to make it? Approach: Purpose of this research was to initial researching of this problem, necessary conditions, inventions, design needed devices, system and testing them. In this case main problem is how to satiate … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 9,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerobic Biodegradation of Per-Treated Methyl Tert-Butyl Ether By Ozonation in an Up-Flow-Fixed-Bed ReactorM. Sadeghi, M. Arbabi, A. Nikpey, G. MardaniProblem Statement: MTBE is a common pollution of environmental and has become an issue of considerable concern in recent years. It is not readily amenable to remove MTBE by conventional techniques in water treatment. In the present study, the feasibility of the continuous aerobic biodegradation of MTBE, was evaluated in an Up- Flow Fixed Bed Reactor (UFBR). Approach: The UFBR … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractFour Dimensional (4-D) BioChemInfoPhysics Models of Cardiac Cellular and Sub-Cellular Vibrations (Oscillations)Kang Cheng, Chang-Hua ZouProblem statement: Cardiovascular Diseases (CVD) continued to be the leading cause of death. Failure or abnormal cardiac cellular or sub-cellular vibrations (oscillations) could lead failure or abnormal heart beats that could cause CVD. Understanding the mechanisms of the vibrations (oscillations) could help to prevent or to treat the diseases. Scientists have studied the mechanisms for more than 100 years. To … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 15 Jun 2009 · 7,057 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerobic Biostabilization of Old MSW LandfillsM.C. ZanettiMany years after the end of the cultivation phase, landfills may generate intense odours, toxic and explosive gases and heavily-polluted leachate. A wide-spreading trend in the management of MSW landfills is represented by the forced aeration of wastes in order to achieve the stabilization, reducing the negative environmental impact of uncontrolled sites (old landfills which can be definitely considered as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,233 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Constructed Wetland Biological Integrity Using Aquatic MacroinvertebratesC. Galbrand, I. G. Lemieux, Abdel E. Ghaly et al.A surface flow constructed wetland consisting of seven cells was used to treat the leachates from a decommissioned landfill. Wetland monitoring was performed by evaluating the treatment efficiency of the landfill leachate and the wetland biological integrity of the wetland. The water quality samples were analyzed for iron, manganese, phosphorus (orthophosphate), pH, dissolved oxygen (DO), nitrogen (ammonia, nitrate, nitrite and … …OnLine Journal of Biological Sciences, Vol. 7, Issue 2 · 31 Dec 2007 · 7,415 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of The Biological Integrity of The Native Vegetative Community In A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC. C. Galbrand, A. M. Snow, Abdel E. Ghaly, R. CôtéA study was conducted to evaluate the biological integrity of a constructed wetland receiving landfill leachate and stormwater runoff from the Burnside Industrial Park, Dartmouth, Nova Scotia. The biological integrity of the constructed wetland was tested in the second growing season using vegetative community monitoring. The metrics analyzed were species diversity, species heterogeneity (dominance) and exotic/invasive species abundance. There was … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Canadian Regulations and Remediation Methods for Diesel Oil Contaminated SoilsD. G. Rushton, A E. Ghaly, K. MartinellDiesel fuel released into the environment can contaminate ground water, degrade potable water supplies and cause the collapse of fisheries. They are toxic to both animals and humans and can affect the liver, lungs, kidneys, and nervous system leading to cancer as well as immunological and reproductive effects. The objectives of this study were to review current Canadian regulations pertaining … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 8,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical and Biological Warfare: Should Rapid Detection Techniques Be Researched To Dissuade Usage? A ReviewMark R. Hurst, Ebtisam WilkinsChemistry, microbiology and genetic engineering have opened new doorways for the human race to propel itself to a better future. However, there is a darker side to Bioengineering. One element of this is the manufacture and proliferation of biological and chemical weapons. It is clearly in the interest of humankind to prevent the future use of such weapons of mass … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,861 accessesView PDFCite
