Research ArticleOpen accessIn the abstractImpact of Bulldozer's Engine Load Factor on Fuel Consumption, CO2 Emission and CostVladislav Kecojevic, Dragan KomljenovicProblem statement: Bulldozers consume a large amount of diesel fuel and consequently produce a significant quantity of CO2. Environmental and economic cost issues related to fuel consumption and CO2 emission represent a substantial challenge to the mining industry. Approach: Impact of engine load conditions on fuel consumption and the subsequent CO2 emission and cost was analyzed for Caterpillar bulldozers. Results … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 9,144 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeight of Evidence Allocates Mineral Depositional ZonesAbdullah A. Bokhari, Guang Dao HU, Rani FouadProblem statement: Yunnan province in general and Pulang area in particular is geological rich area which prevents field study in multi locations due to high risk outcrop. Approach: New technology such as Geographic Information System (GIS) and an ArcView extension module Arcweight of evidence (WofE) became very handy to provide safety for researchers and allow organization to control their budget. … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 6,986 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeighting Spatial Information in GIS for Copper Mining ExplorationFarhad Hosseinali, Ali Asghar AlesheikhExploration of new mines is vitally important for human life. Geospatial Information Systems (GIS) can be effectively used in the gathering, weighting, analyzing and presenting spatial and attribute information to facilitate the mine exploration process. The success of mine exploration largely depends on: the identification of governing factors, the determination of their impacts and the selection of suitable models to … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 8,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval and Recovery of Uranium using Microorganisms Isolated from North American Uranium DepositsTakehiko TsurutaSome attempts were made to remove and recover uranium that may be present in nuclear fuel effluents and mine tailings using microorganisms isolated from North American uranium deposits. To establish which microorganisms accumulate the most uranium, hundreds strains of microorganisms were screened. Of these strains of microorganisms tested, extremely high uranium accumulating ability was found in some bacteria isolated from … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,765 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Content of Heavy Metal in the Labu Riverbed Sediments: An Assessment of the Level of Pollution Applying Sediment Quality Guidelines and Geoaccumulation IndexAhmad Shoaib Jahesh, Sahibin Abd Rahim, Wan Mohd Razli IdrisRiver bed sediments from thirteen (13) sampling stations, from Labu River were collected in June and December 2014. The aim is to identify the source and ascertain the current levels of heavy metal pollutions. The selected heavy metals (Cr, Cu, Fe, Ni, Zn, As, Cd and Pb) were analysed by using Inductively Couple Plasma Mass Spectrophotometry (ICPMS). Metals were statistically … …American Journal of Environmental Sciences, Vol. 12, Issue 4 · 10 Aug 2016 · 7,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Soil and Water Assessment Tool Model to Estimate Sediment Yield in Kaw LakeD. Alemayehu, R. Srinivasan, P. DaggupatiKaw Lake is one of the reservoirs built by the Army Corps of Engineers in 1976 for the purpose of flood control, recreation, water supply, navigation and fish and wildlife conservation. The Arkansas River flows from Colorado and Kansas before reaching Oklahoma. As it passes through these states, the water carries various kinds of pollutants such as metals from mine … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 16 Dec 2014 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractFUNGAL LEACHING OF IRON ORE: ISOLATION, CHARACTERIZATION AND BIOLEACHING STUDIES OF PENICILLIUM VERRUCULOSUMNeha Chaudhary, Trina Banerjee, Neha Ibrahim, G. SibiPyrometallurgical and hydrometallurgical technologies for recovery of metals from low grade ores require high energy and capital costs. Use of microorganisms in leaching of mineral ores is gaining importance due to the implementation of stricter environmental rules. Microbes convert metal compounds into their water soluble forms and are biocatalysts of leaching processes. This study was performed to isolate and characterize … …Current Research in Microbiology, Vol. 5, Issue 1 · 25 Sep 2014 · 8,001 accessesView PDFCite

Awomeso, G. O. Oluwasanya et al.Non-cancer hazard index for inhabitants exposed to heavy metals in surface and groundwater of the abandoned metal mine in Igun-Ijesha area were evaluated. A total of thirty-eight water samples were collected from surface and ground water sources in the study area between September 2012 and February 2013 and the concentrations of heavy metals were determined using Atomic Absorption Spectrophotometer. Non-cancer … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 10 May 2014 · 8,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractCONSTRAINT INFORMATIVE RULES FOR GENETIC ALGORITHM-BASED WEB PAGE RECOMMENDATION SYSTEMS. Prince Mary, E. BaburajTo predict the users navigation using web usage mining is the primary motto of the web page recommendation.
