Research ArticleOpen accessEvery word in the titleEffect of Dose-Response of Zinc and Manganese on Siderophores ProductionMehri Ines, Khessairi Amel, Turki Yousra et al.Problem statement: This study was conducted to find and determine whether the siderophores of the four environmental Pseudomonas spp. isolates possess a sequestering activity towards essential transition metals (Zn and Mn) other than iron. Approach: Four fluorescent Pseudomonads isolated from various environments, were characterized analytically (Isoelectric focusing), biologically (pyoverdine-mediated uptake) and genetically (16S rDNA sequencing). By means of spectrophotometric measurements, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 10 Mar 2012 · 7,768 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpectral and Luminescence Properties of Manganese Doped Sodium Lead Alumino Borosilicate Glass SystemK. Vijaya Babu, A. Subba Rao, K. Naresh Kumar, M. Venugopala RaoNa2O-PbO-Al2O3-B2O3-SiO2 glasses mixed with different concentrations of MnO (ranging from 0.3 to 0.9 mol %) was prepared by melt quenching technique. The samples were characterized by X-ray diffraction technique, Optical absorption and Photo luminescence technique. A prepared glass sample is confirmed by X-ray diffraction spectra. The optical absorption spectra of these glasses exhibited a predominant broad band peak at 21,052 … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 22 Nov 2019 · 7,114 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMineralogy and Chemistry of Coronadite from Middle Cambrian Manganese Deposits at Wadi Dana, Southern JordanAhmad Al-Malabeh, Tayel El-HasanCoronadite was reported from the upper-most horizons of the Middle Cambrian sediments at two locations in Wadi Dana, central Wadi Araba and Jordan. The unit is composed of dolomite, limestone and shale. Geochemical investigations show appreciable variations in Mn, Pb, Fe, K and Ba contents in the coronadite between the two studied sites. Pb was found to increase downward in … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEFFECT OF MICRONUTRIENTS-ENRICHED FERTILIZERS ON BASAL STEM ROT DISEASE INCIDENCE AND SEVERITY ON OIL PALM (ELAEIS GUINEENSIS JACQ.) SEEDLINGSFabien Fonguimgo Tengoua, Mohamed M. Hanafi, A. S. Idris et al.Basal stem rot caused by Ganoderma boninense constitutes a serious threat to oil palm industry in Southeast Asia, especially in Malaysia and Indonesia and in Papua New Guinea and Pacific Islands. It is also expanding in some oil palm growing countries in Latin America and Africa and will soon become a worldwide concern to oil palm cultivation. To date, none … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 5 Dec 2014 · 8,014 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA NEW THERMAL PROCESS FOR THE RECOVERY OF METALS FROM ZINC-CARBON AND ALKALINE SPENT BATTERIESGirolamo Belardi, Roberto Lavecchia, Franco Medici et al.The aim of this study is the thermal recovery of manganese and zinc from a mixture of zinc-carbon and alkaline spent batteries containing 40.9% of Mn and 30.1% of Zn after a preliminary physical treatment. Separation of the metals is carried out on the basis of their different phase change temperatures, the boiling point of zinc being 906°C and 1564°C … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 26 Jul 2014 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVARIABILITY IN THE LIGNINOLYTIC ENZYMES ACTIVITY BY LENTINULA EDODES IN SUBMERGED CULTURE WITH LIGNIN AND GLUCOSECitlalli Harris-Valle, Elisa Valenzuela-Soto, Alfonso Sánchez et al.The white-rot basidiomycete Lentinula edodes is the second most edible mushroom cultivated on the world. This fungus decomposes cell-wall associated macromolecules, is a natural degrader of lignin polymers. The differences in enzyme activities between strains of L. edodes provided useful information about the participation of enzymes in different development stages of the fungus. The effect of lignin on the fungal … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 28 Apr 2014 · 7,845 accessesView PDFCite

Research ArticleOpen accessIn the keywordsTreatment of Stormwater Runoff and Landfill Leachates Using a Surface Flow Constructed WetlandA. Snow, A. E. Ghaly, R. CoteA surface flow wetland was constructed in the Burnside Industrial Park, Dartmouth, Nova Scotia, to treat stormwater runoff from the surrounding watersheds which are comprised primarily of commercial properties and two former landfills. The aim was to protect a freshwater ecosystem that consists of a 4.6 km long brook and two lakes. The ability of the constructed wetland to retain … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,747 accessesView PDFCite
Research ArticleOpen accessIn the keywordsWater Quality Assessment of A Constructed Wetland Treating Landfill Leachate and Industrial Park RunoffC. Galbrand, I. G. Lemieux, A. E. Ghaly et al.A surface flow constructed wetland was used for the treatment of landfill leachate and industrial park runoff. The wetland consisted of seven cells and was designed as a kidney shape to facilitate high retention time. The water quality was assessed for iron, manganese, phosphorus (orthophosphate), pH, dissolved oxygen (DO), nitrogen (ammonia, nitrate, nitrite and TKN), chemical oxygen demand (COD), total … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,368 accessesView PDFCite
