Research ArticleOpen accessIn the keywordsPORE-PRESSURE PREDICTION FROM SEIMIC DATA IN PARTS OF THE ONSHORE NIGER DELTA SEDIMENTARY BASINEmujakporue Omokenu GodwinPore pressure prediction in parts of the Onshore Niger Delta Sedimentary Basin using seismic reflection data has been carried out. The Bower’s technique of velocity-to-pore pressure transform was adopted. The seismic velocities were derived from the seismic data using layer cake velocity model and were later compared with the available sonic logs velocities obtained from the area. Parameters in the … …Physics International, Vol. 4, Issue 2 · 20 Mar 2014 · 7,437 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMathematical Model Predicting the Critical Heat Flux of Nuclear ReactorsChien-Hsiung Lee, Lih-Wu Hourng, Kuo-Wei LinBoiling heat transfer system keeps a nuclear power plant safe without getting over-heated. Crisis will occur if the dissipated heat flux exceeds the critical heat flux value. This study assumes the flow boiling system at high heat flux is characterized by the existence of a very thin liquid layer, known as the &#34sublayer&#34, which is trapped between the heated surface … …Journal of Computer Science, Vol. 8, Issue 12 · 12 Dec 2012 · 7,695 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMixing Patterns and Residence Time Determination in a Bubbling Fluidized Bed SystemA. E. Ghaly, K. N. MacDonaldFluidized bed gasification can be used to convert the solar energy stored as carboneous compounds in biomass into a carbon neutral fuel with reduced emissions. Canada produces 20.57 million tonnes of wheat straw annually which could be used for green energy production. Wheat straw residue gasification has the capability of replacing 7.5 % (0.62 EJ) of Canada’s annual fossil fuel … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,115 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Melatonin in Prevention of Neuropathy in STZ-Induced Diabetic RatsNasser Zangiabadi, Vahid Sheibani, Majid Asadi-Shekaari et al.Problem statement: Diabetes mellitus occurs mainly with chronic polyneuropathy, and oxidative stress plays an important role in emergence of most neurologic and behavioral changes in diabetic patients. Many studies have focused on the beneficial effects of various antioxidants such as melatonin on diabetic neuropathy. The aim of this study is to evaluate the effect of melatonin in prevention of neuropathy … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 2 · 17 Sep 2011 · 9,358 accessesView PDFCite
Research ArticleOpen accessIn the keywordsResearches Concerning the using of Moven© Inertial Navigation System in Monitoring the Male Triple Jump EventMihilescu Liliana, Mihai Ilie, Bidiugan RaduProblem statement: This study aims to highlight ways of using Moven© inertial navigation system applied in the monitoring of the male triple jump event technique. Inertial navigation system involves the use of some elements to determine the coordinates and speed of a body by processing information related to its acceleration. Approach: The research results point out that this equipment can … …Journal of Social Sciences, Vol. 7, Issue 3 · 16 Jul 2011 · 7,365 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRecycled High-Density Polyethylene and Rice Husk as a Wetted Pad in Evaporative Cooling SystemNitipong Soponpongpipat, Sukum KositchaimongkolProblem statement: The low cost and easy-to-find materials, for being used as wetted pad of evaporative cooling system, are necessary for agriculture. This study, thus, studied the evaporative cooling efficiency and pressure drop of recycled High-Density Polyethylene (HDPE) and rice husk as a wetted pad in evaporative cooling system. Approach: The study was done by establishing the tested wetted pad … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHigh Rate-Dependent Interaction Diagrams for Reinforced Concrete ColumnsTaher Abu-Lebdeh, Sameer Hamoush, Wonchang Choi, Moayyad Al NasraProblem statement: There is a need to better understand the rate dependence behavior of reinforced concrete structures in order to improve their response to impact and blast loads. Analysis and design of reinforced concrete structures subjected to seismic loadings has been recommended in many FEMA guidelines. However, reevaluation of design becomes extremely important in cases where large deformations are expected … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 8,020 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluences of Short Discrete Fibers in High Strength Concrete with Very Coarse SandMahyuddin Ramli, Kwan Wai HoeProblem statement: High Strength Concrete (HSC) normally content high cementitous amount and low water binder ratio. However, these would cause substantial volume changes to the concrete and therefore affected the strength development. In addition, the brittleness of HSC was increased when silica fume used as partial cement replacement to achieve high strength. Approach: This study discussed the effects of incorporated … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApproximate Solutions of a Higher Order MHD Flow of a Uniformly Stretched Vertical Permeable Surface in the Presence of Heat Generation/Absorption which Resulted from a Quadratic ReactionO. K. KorikoHigher order MHD flow of a uniformity stretched vertical permeable surface in the presence of heat generation/absorption which resulted from a quadratic reaction was studied. The resulting coupled nonlinear partial differential equations is solved by asymptotic expansion. It was discovered that the maximum value of velocity occurs in the body of the fluid close to the surface not at the … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,445 accessesView PDFCite
