Research ArticleOpen accessIn the keywordsEstablishment of Readily Mathematical Formulation for the Evaluation of Slope Stability in Earth-Fill DamsSalah Saleh, Majda Ibobakr Almhdi AmerThe assessment of slope stability has been considered to be one of the most common issues to deal with by geotechnical engineers. This is due to the amount of destruction that can be brought up by the slope failure of soil masses to roads, railways, and earth dams, for example. Therefore, the stability of soil mass slopes must be carefully … …Journal of Mathematics and Statistics, Vol. 19, Issue 1 · 13 Nov 2023 · 5,181 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStability 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 keywordsKey Factors in the Face Stability Analysis of Shallow TunnelsDaniel Dias, Pierpaolo OresteStability of the excavation face in shallow tunnels and in poor ground is at present a relevant problem in tunnelling. A new calculation procedure is illustrated in this study for the analysis of the effect on the face stability in shallow tunnels of the following key factors: pre-support structures, presence of groundwater, free length of the tunnel (length of the … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimate of Safe Angle for Cut Slopes Under Different Geology and Rainfall Intensity in Central NepalPrabin Shrestha, Khomendra Bhandari, Mahendra Acharya et al.This research has been carried out on a cut slope of Kathmandu-Terai Fast Track Road near Koppugaon located at Dakshinkali Municipality, Kathmandu. The cutting of the slope without considering the possible effects of geological parameters of slope material may cause unexpected slope failures which may cause loss of lives and properties. This research deals with the effects of rainfall and … …Current Research in Geoscience, Vol. 13, Issue 1 · 26 Nov 2024 · 9,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstructing Gibbs Measure in a Rigorous WayFarida Kachapova, Ilias KachapovEquilibrium statistical mechanics studies mathematical models for physical systems with many particles interacting with an external force and with one another. In this paper we describe an interaction model that generalizes several of these models in one model. An infinite model is constructed as the limiting case of finite interaction models, that is as a thermodynamic limit. The key point … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 29 Oct 2019 · 6,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch of Effect of Peculiarities of Creasing a Polymer Sheet Material on a Rigid Base on Parameters of a Folding OperationIl'dus Zakirov, Yuriy Kataev, Alexandr Nikitin, Nargiz FaizullinaFolded elements are widespread in design of various products. They are made of sheet metal, cardboard, plastics or other materials. For example, heat exchangers, printed products, cardboard or plastic folders, folded fillers for three- or multilayered panels, which are made of paper, cardboard or plastics material can be mentioned. Although folded fillers are significantly advanced in terms of structural or … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 20 Aug 2017 · 7,542 accessesView PDFCite

Research ArticleOpen accessIn the abstractAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Dynamics of a General Predator-Prey SystemM. M.A. El-Sheikh, S. A.A. El-Marouf, Z. M. AlaofyProblem statement: In this study a general two dimensional predator-prey model is considered. The dynamic and existence of equilibrium points are studied. Conclusion/Recommendations: Hopf bifurcation is discussed. The existence and uniqueness of limit cycles is proved. Special cases are considered to justify our results. …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 28 Oct 2011 · 7,322 accessesView PDFCite
