Research ArticleOpen accessIn the keywordsNumerical Study of Static and Dynamic Instabilities of Pinned-Pinned Pipe under Different ParametersDahmane Mouloud, Zahaf Samir, Benkhettab Mohamed, Boutchicha DjilaliIn this study, the natural frequencies of the pipe transporting an fluid resting on an elastic Winkler-type and the critical velocities of instabilities are obtained by the standard finite element method. A dynamic characteristic of a pipe carrying internal fluid undergoes mechanical load due to inertia effect of fluid, Coriolis force, fluid kinetic force due to fluid flow velocity, dynamic … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 21 Nov 2020 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPhysical and Geometrical Effects on the Vibratory Pattern of a Pipe Carrying Fluid FlowDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.In this research, the first natural frequencies and critical velocities of a fluid flow-conveying pipe are obtained with finite element method. By discretizing the structure wall and fluid flow, starting from beam type with two degrees of freedom per node. We determine the equation of motion from the fluid-structure coupling using Lagrange energy principle. Parameters frequencies and critical velocity of … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 22 Oct 2020 · 11,396 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExploring Alternative Solutions Regarding Conservation AgricultureReza Movahedi, Hadi Fathi, Mousa Aazami, Somaye LatifiProblem statement: Studies show that no effective measures have been taken towards conservative agriculture in Iran. Social, economical and technical agricultural factors and conditions need to be provided to meet conservation agriculture at the farm, regional and national level. Accordingly, this research aimed at exploring some solutions to protect and conserve agriculture. Approach: To achieve this, of all 100 populations, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 31 Jan 2011 · 7,944 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMethods of Utilizing Tropical Peat Land for Housing SchemeYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper discusses some of the methods and recent technologies in utilizing cheap marginal land such as tropical peat for housing scheme. Buildings on peat are usually suspended on piles, but ground around it may still settle. Therefore a suitable method of construction should be tackle to overcome serious problem such as localized sinking and slip failure, massive primary and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,669 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFinite Element Study Using FE Code (PLAXIS) on the Geotechnical Behavior of Shell FootingsBujang B.K. Huat, Thamer A. MohammedThis study describes a study on the geotechnical behavior of shell footing using a non-linear finite element analysis with a finite element code, PLAXIS. The shell footing is found to have a better load carrying capacity compared with the conventional slab/flat footing of similar cross sectional area. The FE analysis also showed a reasonably good agreement with the laboratory experimental … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,884 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReliability-Based Earthquake Design of Jacket-Type Offshore Platforms Considering Pile-Soil-Structure InteractionBehrouz Asgarian, Hossein AgheshluiThere are plenty of uncertainties in environmental condition of ocean and also in platform element capacities. Reliability-based method could consider these uncertainties. A reliability-based earthquake design method was used to determine the earthquake LRFD parameters for two conventional, steel, pile-supported (template-type) offshore platforms located in the Persian Gulf. The pile-soil-structure interaction, the buckling and postbuckling behavior of the braces were … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Analysis of Honey Production in Chitwan District, NepalSushmita Bhatta, Suraksha Baral, Jay Prakash DattaApiculture is being practiced in Nepal from time immemorial. Economic analysis of honey production in Chitwan district was carried out to analyze profitability along with resource use efficiency in different enterprise system of beekeeping. The Categorization of beekeepers was done according to the number of beehives as small, medium and large. A total of 60 beekeepers were proportionately selected which … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 3 Jan 2021 · 8,676 accessesView PDFCite
