Research ArticleOpen accessIn the abstractNitrifying, Denitrifying and Heterotrophic Biomass Present in Moving Bed-ReactorAndreliza Carolina Del Grossi Oliveira, Camila Zoe Correa, Kátia Valéria Marques Cardoso Prates, Deize Dias LopesThis study was carried out to evaluate the main bacterial communities related to the removal of nitrogen in a moving bed-reactor treating landfill leachate, relating the physico-chemical parameters with the existence of these organisms in the mixed liquor (non-attached microorganisms) and Support Material (SM). The system was operated in two phases: Phase I (without effluent recirculation) and II (with recirculation, … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 25 Jan 2017 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Prototype of a Small-Scale Solar Power Plant: dynamic Simulation and Thermoeconomic AnalysisAnnamaria Buonomano, Francesco Calise, Maria VicidominiThe paper presents an innovative prototype of a solar power plant, purposely designed for small-scale applications such as residential and/or small commercial buildings. The system consists of 10 kWe Organic Rankine Cycle (ORC) plant and innovative solar thermal collectors. In particular, 235 m2 of flat-plate evacuated solar collectors are designed to heat diathermic oil up to 180°C. A variable volume … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 8 Feb 2016 · 8,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeat Transfer Numerical Analysis of a Thermochemical Solar ReactorA. Vázquez-Rodríguez, J. R. Varela-Ham, R. Avalos-Zuñiga et al.In this study a 2D transient temperature distribution in a one-dimensional thermochemical solar reactor of gas-particles is presented. The gas-particles medium is contained in a reactor where an endothermic chemical reaction of some oxide-metal at high temperature is expected to be occurred. The reactor receives the concentrated solar power on the reactor walls, or directly to the gas-particles medium. As … …Energy Research Journal, Vol. 5, Issue 2 · 6 Jan 2015 · 6,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractSIMULATION OF THE PROCESS OF FLOW SEPARATION AT THE ENTRANCE OF SQUARE ASPIRATING PORTOlga A. Averkova, Ilya V. Kryukov, Kirill V. Plotnikov et al.We consider the flow at the inlet to the suction square hole with sharp edges, which is located in an infinite space. The purpose of this study is to construct a mathematical model of flow separation at the entrance to square suction canal with sharp edges, located in infinite space, by using square vortex frameworks. As a part of ideology … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 12 Nov 2014 · 6,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractCoupled Hydrodynamic-Water Quality Model for Pollution Control Scenarios in El-Burullus Lake (Nile Delta, Egypt)A. El-Adawy, A. M. Negm, O. C. Saavedra V et al.El-Burullus Lake is affected by increasing and extensive human activities, rapid social-economic development and the construction of fish ponds nearby. This has significantly impacted the health of the lake eco-system. On the foundation of the two-dimensional depth averaged hydrodynamic model, distributions of the salinity, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Ammonium (NH4) were modeled. … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 10 Nov 2014 · 7,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Evaluation of a Low-Density Biomass Feeding System for Fluidized Bed GasifiersA. E. Ghaly, A. Ergudenler, S. Alsuhaibani, V. V. RamakrishnanFor efficient operation of a biomass gasifier, the biomass material must be fed continuously to the system. A feeding system for chopped straw and rice husk was designed, constructed and evaluated. It consisted of: a frame, a hopper, an auger, two agitators, a drive system and a power unit. Initial testing showed that wheat straw and rice husk, being highly … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 7 Nov 2013 · 8,039 accessesView PDFCite
Research ArticleOpen accessIn the abstractDownstream Ecocide from Upstream Water PiracyMiah Muhammad AdelUpstream India and downstream Bangladesh share more than 50 international rivers. India has set up water diversion constructions in more than 50% of these rivers, the largest one being on the Bangladesh’s northwest upon the Ganges River, puts Bangladesh’s Gangetic ecosystem at stake. In some border rivers, India has set up groins on her side of river banks. Also, Indian … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 4 Sep 2012 · 9,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Change Adaptation in Acid Sulfate LandscapesChuxia LinOxidation of sulfide minerals produces sulfuric acid and consequently creates Acid Sulfate Landscapes (ASLs), which represent one of the most degraded types of land-surface environments. Although acid sulfate-producing weathering is a naturally occurring process, it is markedly facilitated by human intervention. Mining is by far the dominant anthropogenic cause for the creation of inland acid sulfate footprints while land reclamation … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 7 Jul 2012 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Gas Velocity and Temperature on Nitric Oxide Conversion in Simulated Catalytic ConverterSathaporn ChuepengProblem statement: Gaseous emissions from gasoline engine such as carbon monoxide, unburned hydrocarbon and nitrogen oxides were usually reduced in three-way catalytic converter simultaneously around theoretical fuel and air combustion. Engine speed and load and other parameters were varied over a wide range of operating conditions, resulting in different exhaust gas composition and condition intake into catalytic converter. This work … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 27 Jun 2012 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicity of Industrial Wastewater Acting Singly or in Joint-Ratios on Clarias gariepinusAina Olubukola Adeogun, Azubuike Victor ChukwukaFreshwater ecosystems were the most vulnerable to pollution due to their easy accessibility for disposal of wastewaters leading to deterioration of water quality. Ona river, Ibadan, Nigeria is part of a dense network of inland watercourses emptying into the Lagos lagoon and receives industrial effluents from a food and beverage industry. The single and joint-action toxicity of effluents from these … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 7,024 accessesView PDFCite
