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 · 9,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Magnetic Field on the Formation of Spin-polaron in Mn-Zn FerritesH. M.El SayedThe effect of magnetic field on the transport properties of Mn-Zn ferrite was studied. It was found that, the resistivity has an inverse relation with the applied magnetic field. This was attributed to the reduction of the scattering between the charge carriers and the disordered spins. Also, it was found that, the activation energy in the paramagnetic region is strongly … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2007 · 6,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Management Systems in Local Authorities: The Case Study of the Cesana Torinese Municipality, a Turin 2006 Olympic SiteSerena Botta, Claudio ComoglioEnvironmental certification according to the ISO 14001 standard and EMAS regulation represents an efficient tool for those organizations who want to continuously improve their environmental performances. Even though first thought up for application to the industrial section, in recent years these schemes have also proved to be valid in organizations with territorial competences, such as local authorities. The case study … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,260 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Nutritive Value of Wastewater Grown Barley and its Utilization in Fish FeedA.M. Snow, A. E. GhalyThe feasibility of using wastewater grown barley plants as a component of fish feed was evaluated. The barley plants were grown in a hydroponics system on wastewater from a recirculating aquaculture facility. The effects of wastewater application rate on plant growth and pollution potential reduction were investigated. At the end of the experiment, the average crop heights and yields were … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,878 accessesView PDFCite
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 abstractHospital Wastewater Treatment Using an Integrated Anaerobic Aerobic Fixed Film BioreactorA. Rezaee, M. Ansari, A. Khavanin et al.The design and operation of wastewater treatment systems for hospital is a challenge for wastewater engineers. In this study, a pilot-scale system integrated anaerobic-aerobic fixed film reactor for hospital wastewater treatment was constructed and its performance was evaluated. The aim of the study was the elimination of organic compounds and a significant reduction of bacteria. The system had been operated … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractDrying of Poultry Manure for Use as Animal FeedA. E. Ghaly, K. N. MacDonaldThe poultry industry is one of the largest and fastest growing sectors of livestock production in the world. The estimated 2010 world flock was over 18 billion birds with a yearly manure output of 22 million tonnes. Storage and disposal of raw poultry manure have become an environmental problem because of the associated air, water and soil pollution. Environmental and … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 5 Jul 2012 · 12,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Assessment of Hydroponically Grown Cereal Crops for the Purification of Aquaculture Wastewater and the Production of Fish FeedA. M. Snow, A. E. Ghaly, A. SnowHydroponically grown wheat, barley and oats were examined for their ability to remove nutrients from aquaculture wastewater. Wheat, barley and oats seeds were germinated in water in a hydroponics system. The seedlings then received wastewater from an aquaculture system stocked with Arctic charr. During the experiment, the crops grew rapidly and fairly uniformly and showed no signs of mineral deficiency … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 9,167 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
Review ArticleOpen accessAll words, across the recordAdditive Manufacturing in the Aerospace IndustryLidong Wang, Reed Mosher, Patti DuettThe main advantages of Additive Manufacturing (AM) of metals in the aerospace industry are part consolidation; the reduction of lead time, the construction of complicated structures easily with a great Strength-to-Weight (S:W) ratio; production of parts on-demand with reduced inventory, uncertainty and the costs of supply chains. Ti6Al4V and nickel-based alloys are commonly used AM materials for aerospace parts. Ground-based … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 12 Jun 2024 · 8,106 accessesView PDFCite
