Research ArticleOpen accessEvery word in the titleCrack Analysis of Concrete Arch Dams Using Micro-Planes Damage Based Constitutive RelationsM. Labibzadeh, S.A. SadrnejadAmong the various numerical simulating models of plane concrete, the micro-planes models have an excellent position. These models are not as complicated as microscopic models such as discrete particles models and do not have the shortcomings of macroscopic models based on the stress or strain invariants. The object of this study is the application of author's recently developed micro-planes damage … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 6,978 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstablishment 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 accessEvery word in the titleCharacteristics and Pre-Weaning Growth of Crossbred between Belgian Blue and Wagyu Bulls with Brahman Cross DamsPanjono, Ali Agus, Tety Hartatik et al.This study wasconducted to observe characteristics and pre-weaning growth traits of calvesborn from crossbreeding between Wagyu and Belgian Blue (BB) bulls with BrahmanCross (BX) dams. The experiment was conducted to compare two different crossesBelgian Blue (BB) x BX, Wagyu x BX and also with BX pure breed (BX x BX). Inthe first two crosses, we used Artificial Insemination (AI), while … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 3 · 29 Aug 2022 · 8,069 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetection of Pesticide Residue in Dams and Well Water in Jazan Area, Saudi ArabiaHasan Y. Al-Hatim, Deifalla Alrajhi, Abdul Jabbar Al-RajabThe application of pesticides indoors and on agricultural lands increased dramatically in recent years in the Jazan area (Saudi Arabia) to control termites and the vectors of diseases, such as Rift Valley Fever (RVF) and malaria. This practice increased the potential risk of pesticide contamination of surface water and groundwater. In this study, samples of 44 wells and 3 dams … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 3 Nov 2015 · 7,943 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCrack Growth in Concrete Gravity Dams Based on Discrete Crack MethodA.R. Lohrasbi, R. AttarnejadSeepage is the most parameter in water management safety and in stable agricultural. This seepage is passed through the cracks that are present to some degree in hydraulic structures. They may exist as basic defects in the constituent materials or may be induced in construction or during service life. To avoid such failure in concrete dams, safety would be an … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,078 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGeo-Seismic Environmental Aspects Affecting Tailings Dams FailuresJuan M. Mayoral, Miguel P. RomoSeismic performance evaluations of tailings dams are essential for characterizing the geo-environmental risks posed by these earthen structures, which should include the geotechnical hazards implied by slope instability failure, free board loss and the potential release of contaminants. The observed damage is more important when liquefaction occurs on the dam body and foundation, which often leads to cracking, settlements, tilting … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,086 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Damsites Groutability Using Secondary Permeability Index, Rock Classification (Case Studies)R. Ajalloeian, F. MoeinProblem statement: The dam body and foundation seepage is one of the important points in design parameters. This index is related to the permeability. There fore permeability is one of the basic parameter in design grout curtain, prevent water escape from foundation and avoid negative seepage pressure in borrow materials, so grouting is used. Grouting means injected materials like cement … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstimation 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 accessIn the keywordsIntegrated Analysis of Transcriptomic and Metabolomic Responses in Rice Resisting False SmutYanmin Yu, Haiying Liu, Hongtao Wu et al.Rice false smut, caused by Ustilaginoidea virens, is an important fungal disease that reduces both grain yield and quality. To dissect the molecular basis of resistance, we combined transcriptome sequencing and metabolite profiling in resistant and susceptible rice cultivars. Transcriptome sequencing revealed more than 8,500 genes with altered expression patterns after infection, while metabolite profiling detected over 700 significantly changed … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 27 Aug 2026 · 1,057 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMacroinvertebrate Communities Differences on Riverine Parts and Reservoirs of Zarrineh RiverR. Ahmadi, A. Aliyev, M. Seidgar et al.This study was conducted to identify present macro invertebrate’s fauna in reverine and reservoir parts of the Zarrinehrood River for fisheries purposes. The abundance and species composition of macro invertebrate were analyzed and compared in various parts of the Zarrinehrood River (west Azerbaijan, Iran) during November 2008-February 2009 to evaluate the rivers benthic fauna as a resource of fish and … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 24 Feb 2012 · 8,150 accessesView PDFCite
