Research ArticleOpen accessIn the abstractPermeability, Strength and Filtration Performance for Uncoated and Titania-Coated Clay Wastewater FiltersMasturi, Silvia, Mahardika Prasetya Aji et al.Problem statement: Wastewater problems continue to be a relevant issue, particularly in urban areas. One promising low-cost material for manufacturing porous ceramics as water filter is clay. Clays can be blended with other materials such as polymers to obtain functional ceramic materials. Approach: Ceramic wastewater filters were fabricated from clay using both sol-gel and simple mixing methods followed by hot-pressing … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,399 accessesView PDFCite
Research ArticleOpen accessIn the abstractRiver Embankment and Bank Failure: A Study on Geotechnical Characteristics and Stability AnalysisMd. Bellal Hossain, Toshinori Sakai, Md. Zakaria HossainProblem statement: Embankment failure and riverbank erosion are common problem in Bangladesh. Almost every year earthen embankments and riverbanks are facing problems like erosion, breaching or retirements. Among many reasons the major causes are considered due to the use of geotechnically unstable materials, improper method of construction, seepage and sliding. In this study the problem is considered geotechnical point of … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 11,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Oil Contamination on Geotechnical Properties of Basaltic Residual SoilZulfahmi Ali Rahman, Umar Hamzah, Mohd. Raihan Taha et al.Problem statement: Oil contamination due to accidental spillage or leakage brings hefty damage to the environments. It percolates steadily into subsurface environments and contaminates the soil and water system. Hydrocarbon contamination has not just affected the quality of the soil but will also alter the physical properties of oil-contaminated soil. Approach: This study presented the geotechnical properties of oil-contaminated soils … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 10,271 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerobic Biostabilization of Old MSW LandfillsM.C. ZanettiMany years after the end of the cultivation phase, landfills may generate intense odours, toxic and explosive gases and heavily-polluted leachate. A wide-spreading trend in the management of MSW landfills is represented by the forced aeration of wastes in order to achieve the stabilization, reducing the negative environmental impact of uncontrolled sites (old landfills which can be definitely considered as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudies on Some Properties of Quality and Performance in Wood WindowsTuncer Dilik, Barış AltunThe determination of some quality and performance properties of windows, made of tree species used frequently in industrial window manufacturing and the effects of tree species on those properties have been examined. According to the results of the study by considering regular standards, in the air resistance tests, the classification has been determined as follows: those made of Scots pine … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,863 accessesView PDFCite
Research ArticleOpen accessIn the abstractEMPIRICAL DETERMINATION OF THE AVERAGE ANNUAL RUNOFF COEFFICIENT IN THE MEDITERRANEAN AREAGiovanni Grillone, Giorgio Baiamonte, Francesco D’AsaroRunoff estimation in ungauged basin is a challenge for the hydrological engineers and planners. For any hydrological study on an ungauged basin, a methodology has to be appropriately selected for the determination of runoff at its outlet. Several methods have been used to estimate the basin runoff production. In this study the empirical Kennessey method to determine average annual runoff … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 5 Dec 2013 · 8,225 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFormulation and Evaluation of Ficus benghalensis and Ficus racemosa Aquoues ExtractsDivya Kiran, Upendra Kumar, Krishna Murti, Manish KaushikWe intended to develop a desired ointment for treatment of wound. Main objective of this study was to formulate the ointment with different ointment bases having good consistency, better diffusion and antiseptic properties. To assess the efficacy of uniformity, viscosity, diffusivity, rheology, stability, spreadability, permeability and other physical characteristics were evaluated. Two Formulations, formulation A (Aq. extract of Ficus racemosa) … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,409 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHydrogeological Prognosis with Regard to Realisation of the New Colle Di Tenda Road TunnelCinzia Banzato, Massimo Vincenzo Civita, Adriano Fiorucci et al.Problem statement: The doubling of Tenda pass road tunnel jointing SW France to Piedmont (Italy) was planned to penetrate a complicate rock structure in which several complex play an hydrogeologic role including carbonate-Karst aquifer between flysch impervious complexes. The main problem of the project is the presence of an hydraulic circulation feeding a spring of social and economic great importance … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,367 accessesView PDFCite
