Research ArticleOpen accessEvery word in the titleLow Cost Long Distance Detector for Explosives and Chemical Analysis by IEC ApplicationGeorge H. Miley, Heinrich Hora, Frederick Osman et al.A radiation source for detecting specific chemicals at several meter distances even behind walls, car doors or other barriers is the application of Million electron Volts (MeV) neutrons from nuclear fusion reactions at such low intensities to avoid any danger for human bodies. The chemical analysis consists in the neutron activation of nuclei emitting then gamma radiation of lines very … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,513 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMain Aspects of Tunnel Muck RecyclingRossana Bellopede, Fabrizio Brusco, Pierpaolo Oreste, Maurizio PepinoProblem statement: Italy is one of the first countries in the world as far as the number of tunnels is concerned. Many new tunnels are currently under construction or have been planned (300 km of railway tunnels and 150 km of road tunnels, some more than 500 m long, but also metropolitan tunnels). Tunnels are usually excavated in mountain areas … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 9,338 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFinite Element Analysis of Composite Hardened Walls Subjected to Blast LoadsGirum S. UrgessaProblem statement: There is currently no standard design guideline to determine the number of composites needed to retrofit masonry walls in order to withstand a given explosion. Past design approaches were mainly based on simplified single-degree-of-freedom analysis. A finite element analysis was conducted for concrete masonry walls hardened with composites and subjected to short duration blast loads. Approach: The analysis … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,266 accessesView PDFCite
Research ArticleOpen accessIn the abstractVirtual Assessment of air Pollution Dispersion from Anthropogenic Sudden ExplosionMarvel Lola Akinyemi, Moses Eterigho Emetere, Mojisola Rachel UsikaluThe control of air pollutants from anthropogenic sources seems almost impossible due to numerous influencing factors present in the atmosphere. In this study, we carried out a virtual mathematical experimentation using Math CAD, Mat lab and analytical approximation to estimate the dimensional impact of initial pollutant plume cloud from a sudden volcanic blast and the dynamics of its wind field. … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 9 Apr 2016 · 7,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisk Assessment Study for Storage ExplosiveS. Saiful Azhar, M. Abdul Rahman, M. Saari et al.In Malaysia, there has been rapidly increasing usage in amount of explosives due to widely expansion in quarrying and mining industries. The explosives are usually stored in the storage where the safety precaution had given high attention. As the storage of large quantity of explosive can be hazardous to workers and nearby residents in the events of accidental denotation of … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,098 accessesView PDFCite
