Research ArticleOpen accessIn the keywordsAssessment on the Effect of Formulative Materials on the Viability and Efficacy of Serratia marcescens-a Biocontrol Agent Against Fusarium oxysporum F. sp. cubense race 4A. S. Y. Ting, M. T. Fang, C. S. TeeProblem statement: Application of biocontrol agents to the field in pre-existing free-cell forms often results in poor cell viability which subsequently affects their efficacy in suppressing pathogen development. There is therefore a need to bioformulate these biocontrol agents not just to enhance their field potential, but for easy storage, delivery and application as well. Approach: In this study, the bioformulations … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,474 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsFoundry Wastes Reuse and Recycling in Concrete ProductionSilvia Fiore, Maria Chiara ZanettiThe industrial process of a cast iron foundry plant located in the North of Italy was analyzed in order to determine the amount and kind of produced wastes. The main fractions are core and moulding sands, muds and powders from dust abatement plants, furnace and ladle slags, and exhaust lime, making about 750-800 t/d of residues for a production of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,956 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPrediction and Remediation of Water Quality in Monitoring Potential of Acid Mine DrainageNur Athirah Mohamad Basir, Wan Zuhairi Wan Yaacob, Nuur Hani Mohammed et al.Acid Mine Drainage (AMD) associated with both active and abandoned mining operations related to sulfide minerals, oxidation of pyrite affording an acidic solution that contains toxic metal ions. Result shows that pH value of water in Kg. Aur, Chini and Sg. Lembing are acidic with value of 2.81, 4.16 and 3.60 respectively. Maximum concentrations of heavy metals in the study … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 24 May 2019 · 7,014 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation and Beneficiation of Bentonitic Clays from Pindiga Formation in Benue TroughB. B.M. Dewu, I. I. Funtua, M. O.A. Oladipo et al.Problem statement: This study aimed at evaluating and beneficiating Bentonitic clays of Pindiga Formation from the upper Benue trough in northeastern Nigeria to meet the standard required for use in oil well drilling. This will reduce the dependence on imported Bentonite into the country, increase foreign exchange, improve the country’s economy and create employment opportunities. Approach: Three clay samples from … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 16 Jan 2012 · 8,570 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn in vitro Assessment on the Efficacy of Clay-Based Formulated Cells of Pseudomonas Isolate UTAR EPA2 for Petrol DegradationA. S.Y. Ting, M. T. Fang, C. S. TeeProblem statement: Application of free-cell forms is usually impractical to achieve satisfactory bioremediative effect because the microbes are encumbered by the biotic and abiotic stresses from the environment. Approach: In this study, a hydrocarbon-degrading bacterium (Pseudomonas isolate UTAR EPA2) was formulated with various combinations of formulative materials, comprising of clay-based carrier materials such as Bentonite (B) and Kaolin (K), enrichment … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Aug 2010 · 7,653 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBehavior of Stabilized Peat Soils in Unconfined Compression TestsWong Leong Sing, Roslan Hashim, Faisal Haji AliProblem statement: Deep stabilized peat columns were known to be economical at forming foundations to support highway embankments constructed on deep peat land. However, failure in the formation of the columns with adequate strength was often attributed to unsuitable type and insufficient dosage of binder added to the soil. Organic matter in peat was known to impede the cementing process … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,459 accessesView PDF Cite
