Al-Harbawi, He Qiang, Zhai JunThe study reports the results of a laboratory scale investigation aimed at evaluating the effectiveness of mature municipal landfill leachate treatment by a biological stage (used SBBR as a biological treatment) and Chemical precipitation (Used MAP precipitation (magnesium ammonium phosphate)) to study the nitrogen removal capabilities for treatment of sanitary landfill leachate containing high ammonia concentration, and the comparison between … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,032 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Precipitation Fluctuation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,603 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCuInSe2 (CIS) as A light Absorption Layer of Photovoltaic Solar-CellsOmar Abdulsada AliArrested precipitation methode used to synthesize CuInSe2 (CIS) nanocrystals were added to a hot solvent with organic capping ligands to control nanocrystal formation and growth. CIS thin films deposited onto Soda-Lima Glass (SLG) substrate by spray-coat, then selenized in Ar-atmosphere to form CIS thin films. PVs were made with power conversion efficiencies of 0.631% as-deposited and 0.846% after selenization, for … …Current Research in Nanotechnology, Vol. 7, Issue 1 · 29 Feb 2016 · 14,781 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSEASONAL DROUGHT DYNAMICS IN EL-BEHEIRA GOVERNORATE, EGYPTAmr Mossad, Hazem S. Mehawed, Ahmed El-ArabyDrought is the most damaging climate-related hazards due to the prolonged absence of precipitation. Therefore, understanding the drought dynamics is important for irrigation water management to mitigate the negative impacts on agriculture. In this study, Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) were used as effective tools for tracking the changes of water status occurred at five … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 4 Apr 2014 · 7,621 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEmerging Trends in Designing Short and Efficient Protein Purification ProtocolsSaurabh Gautam, Joyeeta Mukherjee, Ipsita Roy, Munishwar Nath GuptaProtein purification is carried out in both academic and industrial sectors. Both non-chromatographic approaches (precipitation, crystallization, partitioning) and chromatographic methods are used. When recombinant proteins are over expressed in foreign hosts, inclusion bodies are obtained. Many purification methods can be used to refold proteins. Many strategies allow one to avoid formation of inclusion bodies. The concept of affinity based separation … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 9,007 accessesView PDFCite
Research ArticleOpen accessIn the keywordsClimate Change in Jordan: A Comprehensive Examination ApproachMoshrik R. Hamdi, Mahmoud Abu-Allaban, Ammar Al-Shayeb et al.Problem statement: Jordan is experiencing harsh water shortage in different parts of the country due to high fluctuations in annual precipitation; the only source of water. In addition, heat waves are becoming more frequent in the region. Precipitation decrement and summer heat waves are being blamed on global warming. This study aimed to detect trends in weather parameters in Jordan. … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 9,402 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy. The monitoring plan … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRainfall Depth-Duration-Frequency Relationships for South Carolina, North Carolina, and GeorgiaJ. P. Raiford, N.M. Aziz, A.A. Khan, D.N. PowellThe depth-duration-frequency curves and isopluvial maps for the region encompassing South Carolina, North Carolina, and Georgia were developed using the available rainfall data. The aim was to update the existing intensity-duration-frequency curves in the region and obtain these curves at ungauged sites throughout the region using the newly developed rainfall frequency analysis techniques. A total of 17 durations ranging from … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,323 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRecovery of Manganese from Zinc Smelter SlagRasoul Khosravi, Rasoul Fatahi, Hossein Siavoshi, Fatemeh MolaeiUsing a software-based experiment design, the application of the leaching process for the extraction of manganese from Zinc Plant Slag (ZPS) was investigated. In this study, the effect of different parameters, i.e., H2SO4 concentration, pulp density, agitation rate, temperature and reaction time, was investigated. Response Surface Methodology (RSM) based on the Central Composite Design (CCD) has been implemented to consider … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 1 Dec 2020 · 7,273 accessesView PDFCite
InvestigationOpen accessIn the keywordsBackpropagation Vs. Radial Basis Function Neural Model: Rainfall Intensity Classification For Flood Prediction Using Meteorology DataSoo See Chai, Wei Keat Wong, Kok Luong GohRainfall is one of the important weather variables that vary in space and time. High mean daily rainfall (>30 mm) has a high possibility of resulting in flood. Accurate prediction of this variable would save human lives and properties.
