Research ArticleOpen accessIn the abstractStability Analysis of Southern Slope of Chenmenshan Open Pit Copper MineMohammed Mnzool, Ling Wan, Zuoan WeiChengmenshan Copper SulphurMine, one of the of the large-scale open pit mine in China, the engineering geology and hydrogeology in the Southern slope of the mine is very complicated and the contact plane between two kinds of sandstone’s form soft-weak layer. Field investigations and reports by operators demonstrated that some instability problems might occur in the southern slope which is … …Current Research in Geoscience, Vol. 3, Issue 1 · 4 Sep 2013 · 6,970 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmploying Electromagnetic Induction Technique for the Assessment of Soil CompactionKhalid A. Al-GaadiAn experiment on a sandy soil field was conducted to investigate the potential of determining soil compaction from apparent soil Electrical Conductivity (ECa) measured by Electromagnetic Induction (EMI) technique. A soil conductivity meter (EM38) was used to measure ECa under four soil Moisture Contents (MC) (4.965.336.94 and 8.0%) and a range of Soil Compaction (SC) levels (on the average, from … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 7 Nov 2012 · 8,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Diesel Contaminated Soils Using Surfactants: Coulumn StudyE. Salehian, A. Khodadadi, B. HosseiniThis study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractImportace of the International Council of Environmental Engineering EducationIstvan PatkoProblem statement: Due to the climatic changes and the ecological variations of the biosphere, global natural resources including the atmosphere, hydrosphere, lithosphere, biodiversities, genetic resources and energy, radiation, electric charge and magnetism, must be safeguarded for the benefit of present and future generations through careful planning and management as appropriate. Approach: The main points of the International Council of Environmental … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 27 Mar 2012 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Applied Study on the Debris Recycling in TunnellingPierpaolo Oreste, Marta CastellanoProblem statement: A simple calculation has shown what the impact of muck created during the construction of a hypothetical 50 km long and 100 m2 cross section tunnel could be on the environment: around 8 million cubic meters would have to be discharged as waste material. One solution to such a problem could be to recycle (almost a part) the … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 27 Mar 2012 · 7,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent and Future Nanotech Applications in the Oil IndustryCocuzza Matteo, Pirri Candido, Rocca Vera, Verga FrancescaProblem statement: Nanotech applications in the oil industry are not completely new: nanoparticles have been successfully used in drilling muds for the past 50 years. Only recently all the other key areas of the oil industry, such as exploration, primary and assisted production, monitoring, refining and distribution, are approaching nanotechnologies as the potential Philosopher's stone for facing critical issues related … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 10,624 accessesView PDFCite

Research ArticleOpen accessIn the abstractNatural Sensitizer for Dye-Sensitized Solar Cells Using Three Layers of Photoelectrode Thin Films with a Schottky BarrierHo Chang, Mu-Jung Kao, Tien-Li Chen et al.Problem statement: This study combines Au nanoparticles with TiO2 nanoparticles to form a Schottky barrier and applies it to the photoelectrode thin film of Dye-Sensitized Solar cells (DSSCs). Approach: First, commercial TiO2 powder (Degussa P25) was put into the alkaline solution to prepare TiO nanotubes (Tnt) by a hydrothermal process. Tnt were sintered at 550° to obtain TntC550 particles and … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Performance of the Peer to Peer Network by Introducing an Assortment of MethodsM. Sadish Sendil, N. NagarajanProblem Statement: Peer to Peer (P2P) systems have grown dramatically in recent years. The most popular type of P2P systems are file sharing networks, which are used to share various types of content over the Internet. Due to the increase in popularity of P2P systems, the network performance of these systems has become a very important issue in the design … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 7,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Buddha Images and Conservation and Adherence to Cultural Values in NortheastAthikan Suksri, Souneth Phothisane, Sastra Laoakka et al.Problem statement: This study is caused by the problem of conservation of the Buddha images to exist in the original condition and by the problem of transference and adherence to indigenous knowledge of local craftsmen. At present there have not yet been systematic and wide conservation and adherence to the Buddha images. Other causes are such as incorrect techniques of … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 7,665 accessesView PDFCite
