Research ArticleOpen accessIn the abstractLevels of Metals and Microbial Biomass in Cobalt Coleman Mine Tailings (Canada) Three Decades after Land ReclamationKabwe Nkongolo, Graeme Spiers et al.Investigations of restored metal contaminated tailings in Canada with regard to their long-term ability to sustain plant and associated microbiological populations are limited. The specific objectives of the present study were to assess (1) The current levels of total and bioavailable metals and (2) Microbial biomass in Cobalt Coleman mine tailings reclaimed in 1990. The level of microbial biomass was … …American Journal of Environmental Sciences, Vol. 19, Issue 1 · 20 Mar 2023 · 6,011 accessesView PDFCite
Research NotesOpen accessIn the abstractThermal Drying Methods on Coal Liquefaction ConversionMehran HeydariThe sample coal used in this work was lignite containing 25% of moisture and 19% of ash from Canada. Drying of lignite coal had considerable influence on the coal liquefaction conversion. Vacuum dried and nitrogen dried samples provided higher conversion than air dried samples. The air drying showed nearly lower conversion, which probably as a result of oxidation. Air Drying … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 12 Mar 2019 · 7,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractMixing Patterns and Residence Time Determination in a Bubbling Fluidized Bed SystemA. E. Ghaly, K. N. MacDonaldFluidized bed gasification can be used to convert the solar energy stored as carboneous compounds in biomass into a carbon neutral fuel with reduced emissions. Canada produces 20.57 million tonnes of wheat straw annually which could be used for green energy production. Wheat straw residue gasification has the capability of replacing 7.5 % (0.62 EJ) of Canada’s annual fossil fuel … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,119 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Socially Responsible Investment Markets (SRI) Using Dynamic Conditional Correlation (DCC) Method: Implications for DiversificationGurudeo Anand Tularam, Eduardo Roca, Victor Siew Howe WongProblem statement: Over the last ten years there has been a phenomenal growth in the amount of funds placed in SRI globally estimated to be around US$6.5 trillion while around US$55 billion in the Australian market. Accurate knowledge of correlation of the Australian SRI market with other SRI markets overseas is crucially important for Australian (SRI) investors for international portfolio … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 4 Nov 2010 · 16,240 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Levan by Bacillus licheniformis for Use as a Soil Sealant in Earthen Manure Storage StructuresAbdel E. Ghaly, F. Arab, N.S. Mahmoud, J. HigginsManure application is not permitted on frozen land in Canada and therefore, manure management and storage are the primary issues facing the agri-food industry. Low-cost, effective and environmentally safe earthen manure storage (EMS) facilities will lower costs and help make the livestock industry more competitive and efficient. The goal of this study was to develop a biological sealing technology for … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,977 accessesView PDFCite
Review ArticleOpen accessIn the abstractProject HARPRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The HARP project, abbreviated from the High Altitude Project, was considered a joint project of the United States Department of Defense and Canada's Department of Defense, originally designed to study low-cost re-entry vehicles. Generally, such projects used rocket launchers to launch missiles, costly and often inefficient. The HARP project used a non-rocket space launch method based on a very large … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 7 Nov 2017 · 19,808 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION OF THE ADEQUACY OF THE WIND SPEED EXTRAPOLATION LAWS FOR TWO DIFFERENT ROUGHNESS METEOROLOGICAL SITESDalila Khalfa, Abdelouaheb Benretem, Lazher Herous, Issam MeghlaouiIncreasing knowledge on wind shear models to strengthen their reliability appears as a crucial issue, markedly for energy investors to accurately predict the average wind speed at different turbine hub heights and thus the expected wind energy output. This is particularly helpful during the feasibility study to abate the costs of a wind power project. The extrapolation laws were found … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 7,445 accessesView PDFCite
Research ArticleOpen accessIn the abstractFactors Associated with Syringe Sharing Among Users of a Medically Supervised Safer Injecting FacilityEvan Wood, Mark W. Tyndall, Jo-Anne Stoltz et al.Vancouver, Canada recently opened a medically supervised safer injecting facility (SIF) in an effort to reduce HIV and overdose risk and public injection drug use. We sought to examine factors associated with syringe sharing among SIF users. SIF users were randomly recruited into a prospective cohort of SIF users known as the Scientific Evaluation of Supervised Injecting (SEOSI) cohort. We … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 10,764 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHEAVY METAL ANALYSIS IN RED OAK (QUERCUS RUBRA) POPULATIONS FROM A MINING REGION IN NORTHERN ONTARIO (CANADA): EFFECT OF SOIL LIMING AND ANALYSIS OF GENETIC VARIATIONAnh Tran, K. K. Nkongolo, M. Mehes-Smith et al.Understanding the dynamic of metals in soil and plants and population diversity in Northern Ontario is essential in determining progress toward ecosystem sustainability in reclaimed sites. The objectives of the present study were to assess the levels of metal content in soils and their accumulation in red oak plants from limed and unlimed sites. Genetic variation in red oak populations … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 25 Jun 2014 · 7,737 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRemoval of Hydrogen Sulphide from WaterS. Edwards, R. Alharthi, A.E. GhalyProblem statement: The concentration of H2S in groundwater is a significant problem in various areas across Canada. Hydrogen sulphide dissolves in ground water imparting undesirable taste and irritating rotten egg smell which makes it unpalatable. Ingestion of sulphides through drinking water can result in stomach discomfort, nausea and vomiting. Humans exposed to high concentrations of H2S for prolonged periods show … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 26 Aug 2011 · 15,129 accessesView PDFCite
