Research ArticleOpen accessPhrase in the titleFull Scale Tests of Short-Term Municipal Solid Waste Incineration Bottom Ash Weathering Before Landfill DisposalFranco Marchese, Giuseppe GenonProblem statement: Natural weathering is the most economic method of treatment in order to reduce the release of heavy metals present in the residue. Approach: The aim of the study was to optimize the minimum weathering times that were useful to reduce the lead release to within the Italian limits for landfill disposal. The mechanism of short-term weathering of MSWI … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,153 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleSpeciation of Chromium in Bottom Ash Obtained by the Incineration of the Leather Waste ShavingsK. louhab, H. AkssasThe evolution of bottom ash morphology and chromium metals behavior during incineration of a leather waste shavings at different incineration temperature have been studied. The Cr, Ca, Mg, Cl rates in bottom ashes, flay ashes and emitted gases in different incineration temperature of the tannery wastes are also determined. The morphology of the bottom ashes obtained by incineration at different … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,485 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEnvironmental Risk Assessment of Coal-Ash-Amended Soil Based on Continuous Planting of PakchoiWenxuan Sun, Liyong Bai, Huihui Ji et al.The agricultural application of coal ash which contains a variety of chemical nutrients may also cause heavy metal pollution of crops and soil. In this study, pakchoi was cultivated for four consecutive seasons in pots of brown soil amended with fly ash or bottom ash. With subsequent plantings, the total concentrations in the four fractions of Pb, Cr and Cu … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 11 May 2021 · 6,862 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalyze the Significance of Age and Height on the Physical and Chemical Properties of Ethiopian Giant Timber BambooYalew Dessalegn, Balkeshwar Singh, Aart W. van VuureThis research aims to examine the properties of culm based on the factors of age and height for structural and industrial purposes. Aged from 1-3 years old of culm and the height was divided into 3 parts which bottom, middle and top. The properties of Giant Timber bamboo in Ethiopia were not investigated so far from the other research work … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 7 May 2021 · 7,034 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Use of Swimmer Bars as Shear Reinforcement in Reinforced Concrete BeamMoayyad Al-Nasra, Naem Asha, Abdelqader Najmi, Taher Abu-LebdehThe behavior of reinforced concrete beams at failure by shear is distinctly different from their behavior by bending, which is considered to be unsafe mode of failure. The shear failure of beams is usually sudden without sufficient advanced warning and the diagonal cracks that develop due to excess shear forces are considerably wider than the flexural cracks. The cost and … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 15 Mar 2013 · 8,134 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBheri-A Unique Example of Biological Complex SystemIndranil Mukherjee, Pranami Bhaumik, Madhusmita Mishra et al.Problem statement: This study is a unique attempt to characterize Bheri (shallow flat bottom waste water fed fishery) as a complex biological system. Approach: The characterization was done both at the qualitative and the quantitative levels. The diverse microbial community and the associated emergent behaviors resulting in integrated resource recovery by the Bheris were analyzed under the lens of complexity … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,770 accessesView PDF Cite
