Research ArticleOpen accessEvery word in the titleHomogenization of Earthquake Catalogue in Terms of Magnitude in Iran and Adjoining RegionNoushin Naraghiaraghi, Mohd Nawawi, Syed Mustafizur Rahman et al.In any seismic hazard assessment a uniform earthquake catalogue is an essential parameter. In this research, an earthquake catalogue of Iran and adjacent areas was studied, using national and international catalogues. The considered region covers a quadrangle limited by 23 to 42°N and 42 to 65°E including Iran and adjacent areas. Earthquake data from the third millennium BC until 2014 … …Current Research in Geoscience, Vol. 6, Issue 1 · 11 Apr 2016 · 13,009 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimplified Analysis of the Lining Behavior During Earthquakes in Deep Rock TunnelsPierpaolo OresteThe sizing of the lining of a tunnel requires to consider not only the static loads transmitted from the surrounding rock, but also the effects of earthquakes on the stresses and strains of the lining. The detailed evaluation of the interaction earthquake-lining using numerical methods typically requires very long calculation time and can be limited to the verification of the … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 4 May 2015 · 6,901 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleECOTOXICOLOGICAL BIOASSAYS OF THE EARTHWORMS ALLOLOBOPHORA CALIGINOSA SAVIGNY AND PHERETIMA HAWAYANA ROSA TREATED WITH ARSENATEAbdelmonem Mohamed KhalilLittle research has been carried out on the effect of arsenate on earthworms. Ecotoxicological laboratory tests are fundamental tools for assessing the toxicity of arsenate to soil organisms. In this study, the impact of arsenate on the survival, reproduction and behaviour of the endogenic earthworms Allolobophora caliginosa and the anecic earthworms Pheretima hawayana has been quantified. The 96-h LC 50 … …OnLine Journal of Biological Sciences, Vol. 13, Issue 3 · 27 Sep 2013 · 7,068 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of the Behavior of Tailings Earthen Dam Under Seismic ConditionsDebarghya Chakraborty, Deepankar ChoudhuryProblem statement: A number of tailings earthen dams have failed during past earthquakes. The failure of tailings dam ultimately results into the release of the stored tailings waste deposit in the surrounding locality. To reduce such damage of tailings earthen dam, a detail method of seismic analysis is very much essential which can be used reliably for the design and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 8,559 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation of Earthquake-Induced Crest Settlements of EmbankmentsRaghvendra Singh, Debasis RoyProblem statement: Freeboard requirement, a major consideration in the design of embankment dams, is controlled to a great extent by the crest settlements during earthquakes. Approach: The parameters that influence earthquake induced crest settlement had been studied using 152 published case histories on performance of embankment dams during earthquakes. Results: Based on the results a correlation had been proposed for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 8,026 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of Sustainable Relief Housing in Ethiopia: An Implementation of Cradle to Cradle Design in Earthbag ConstructionBrooke Barnes, Huantian Cao, Theodore Drab, Jason PearsonProblem statement: Urbanization in Ethiopia resulted in urban poverty and homelessness. In this study, a sustainable relief housing prototype that aided in sheltering homeless citizens was designed. To avoid repeating errors in urban development such as unsustainable resource consumption, it was necessary to look beyond traditional construction materials and methods. Approach: This design applied cradle to cradle design model to … …American Journal of Environmental Sciences, Vol. 5, Issue 2 · 30 Apr 2009 · 7,288 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIonospheric Total Electron Content Response to the December 26, 2004 North Sumatra EarthquakeA. Abdullah, A. F.M. Zain, M. H. Jusoh et al.Problem statement: Ionospheric precursors of earthquake have been studied by scientists and seismologists. This study aims at examining the relationship between the ionosphere and earthquake precursors. The effects of the anomalous electric field that penetrates the ionosphere on the electron concentration can be measured experimentally. This study reports on the variability of the Total Electron Content (TEC) during the December … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,908 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSoil Structure Interaction between Two Adjacent Buildings under Earthquake LoadMahmoud Yahyai, Masoud Mirtaheri, Mehrab Mahoutian et al.In some cases, tall buildings are located in geotechnically unsuitable places, due to their high ratio of height to width; there is risk of uplift and other effects such as overturning and reduction structure serviceability during earthquake. This research is aimed to evaluate the effect of Soil-Structure Interaction (SSI) on seismic behavior of two adjacent 32 story buildings such as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 9,345 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEarthquake Risk Management Strategy Plan Using Nonparametric Estimation of Hazard RateAflaton Amiri, Ramin TabatabaeiEarthquake risk is defined as the product of hazard and vulnerability studies. The main aims of earthquake risk management are to make plans and apply those for reducing human losses and protect properties from earthquake hazards. Natural risk managers are studying to identify and manage the risk from an earthquake for highly populated urban areas. They want to put some … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,744 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntagonism Between Chlorpyrifos and Flaxedil in Toad and Earthworm Neuromuscular TransmissionYong-Chiang Chang, Amauri B. Bartoszeck, Samir A. Madeira, Charles I. AbramsonThe cholinesterase inhibition effect of chlorpyrifos, a commercial insecticide, was tested by its antagonism to the acetylcholine inhibition effect of flaxedil in 30 isolated nerve-sartorius muscle preparations of the toad, compared with its antagonism in 30 isolated nerve cord-body wall muscle preparations of the earthworm. Inhibition and facilitation in this antagonism were measured by changes in depolarizing rate of toad … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 6,389 accessesView PDFCite
