Research ArticleOpen accessIn the abstractPhytoremediation of Anaerobic Digester Effluent for Water Purification and Production of Animal FeedA. E. Ghaly, H.A. FaragThe application of phytoremediation for purification of an anaerobically treated dairy manure and production of forage crops was investigated. Four crops (two cereals and two grasses) were examined for their ability to grow hydroponically and to remove pollutants (nutrients) from dairy wastewater. The preliminary experiments showed that timothygrass and orchardgrass did not perform well as aquatic plants. Only 24 and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 8,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Supplementary Bioavailable Carbon on the Thermal and Biological Kinetic Parameters of the Composting Process of Tomato Plant TrimmingsA.E. Ghaly, F. AlkoaikThree laboratory-scale bioreactors were used to investigate the influence of bioavailable carbon addition on the composting process of tomato remains. Sugar, cheese whey and used cooking oil were used as bioavailable carbon sources. The amounts of materials added to the compost mixture had equal energy contents. The initial moisture contents and C: N ratios of the compost mixtures were maintained … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 6,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreased Production of Nitric Oxide Contributes to Renal Oxidative Stress in Endotoxemic RatBahar Tunçtan, Belma Korkmaz, Hatice Yıldırım et al.Overproduction of reactive oxygen and nitrogen species leads to oxidative stress and decreased total antioxidant capacity, which is responsible for high mortality from several diseases such as endotoxic shock. Nitric oxide (NO) produced by inducible NO synthase (iNOS) during endotoxemia is the major cause of vascular hyporeactivity, hypotension and multiple organ failure. In this study, we investigated whether increased production … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 8,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Anti-Ds-DNA Antibodies and Abnormal Kidney Function Tests in Patients with Lupus NephritisFalah Salim Manhal, Hawra'a Adnan MohammedThe majority of patients with Lupus Nephritis (LN) usually have abnormal findings of kidney function tests. Severe glomerular damage may be observed in some patients and requires prompt therapeutic interventions. High titer levels of anti-ds-DNA antibodies may correlate to some extent with disease activity in lupus nephritis patients. The purpose of this study was to evaluate the relationship between anti-ds-DNA … …American Journal of Immunology, Vol. 12, Issue 2 · 21 May 2016 · 9,076 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Converting Tropical Peat Swamp Forest into Oil Palm Plantation on Water QualitySeca Gandaseca, Noraini Rosli, Mohd Hanafi Idris et al.Peat swamp forest is a unique forest and wetlands ecosystem that recognized as one of the most important reservoir of biodiversity and water resources protection. Rapid development particularly for development, agriculture and plantation in peat swamp forest (PSF) area had given negative impacts to its ecosystem included degradation of its water quality. This study was conducted to determine water quality … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 3 Sep 2015 · 7,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractASSESSMENT OF OIL PALM PLANTATION AND TROPICAL PEAT SWAMP FOREST WATER QUALITY BY MULTIVARIATE STATISTICAL ANALYSISSeca Gandaseca, Noraini Rosli, Mohammad Shawkat Hossain, Chandra Imam AriantoThis study reports the spatio-temporal changes in river and canal water quality of peat swamp forest and oil palm plantation sites of Sarawak, Malaysia. To investigate temporal changes, 192 water samples were collected at four stations of BatangIgan, an oil palm plantation site of Sarawak, during July-November in 2009 and April-July in 2010. Nine water quality parameters including Electrical Conductivity … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 3 Jul 2014 · 8,218 accessesView PDFCite

Research ArticleOpen accessIn the abstractAnaerobic Transformation of Biodegradable Waste; Simultaneous Production of Energy and FertilizerAmirhossein Malakahmad, Syazana Nasrudin, Noor Ezlin Ahmad Basri, Shahrom Md ZainAlmost 40% of the total waste produced in developing countries is made of biodegradable waste. Typically the waste including the biodegradable portion is transported to the so-called landfills without any segregation process, treatment and utilization in advance. Although mitigation practices such as source reduction, reuse and recycle are essential and required to be practiced in any integrated waste management plan, … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 10 Mar 2013 · 7,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecolorization of Distillery Effluent by Thermotolerant Bacillus subtilisSoni Tiwari, Rajeeva Gaur, Priyanka Rai, Ashutosh TripathiProblem statement: Ethanol production from sugarcane molasses generate large volume of effluent containing high Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) along with melanoidin, a color compound generally produced by “Millard reaction”. Melanodin is a recalcitrant compound degraded by specific microorganisms having ability to produce mono and di-oxygenases peroxidases, phenoxidases and laccases, are mainly responsible for degradation of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 14 Mar 2012 · 7,647 accessesView PDFCite
