Research ArticleOpen accessAll words, across the recordBiochar Types from Latrine Waste and Sewage Sludge Differ in Physico-Chemical Properties and Cadmium AdsorptionKoetlisi Andreas Koetlisi, Pardon MuchaonyerwaPyrolysis of latrine fecal waste could produce valuable products for minimizing environmental contamination with heavy metals. The objective of this study was to determine yields, characteristics and cadmium (Cd) sorption of biochar from latrine fecal waste and sewage sludge, as affected by pyrolysis temperature. Slow pyrolysis at 350, 550 and 650°C, was used to produce the biochar. In addition to … …American Journal of Applied Sciences, Vol. 14, Issue 11 · 30 Nov 2017 · 8,517 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCoupled 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 · 7,212 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGROWTH OF YB3+ DOPED LiNBO3 CRYSTALS USING LASER HEATED PEDESTAL GROWTH METHODBariza Boudour, Youcef Boumaiza, Amar BoudourThe growth of LN single crystals free from defects greatly doped with rare earth elements (RE3+) and having a high optical quality is still an unresolved problem. Always, crystals of the niobate lithium contain a deficiency in lithium causing the appearance of intrinsic defects and thus a doping is required for the homogeneity. Our work was aimed to study the … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 17 Feb 2014 · 6,918 accessesView PDFCite
