Research ArticleOpen accessEvery word in the titleHigh Temperature Convective Drying of a Packed Bed with Humid Air at Different HumiditiesJ. Sghaier, S. Messai, D. Lecomte, A. BelghithProblem statement: Drying a packed bed of porous particle at high temperature with varying humidity of hot air is an attractive process. Many researches on experimental and simulation on a fixed bed drying at low and average temperature are proposed. Few studies showed drying at high temperature with humid air or using superheated steam. The latest is compared to dry … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,023 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Storage Temperature on the Stability of Phytonutrients in Palm ConcentratesK. Chandrasekaram, M. H. Ng, Y. M. Choo, C. H. ChuahPalm phytonutrient concentrates; a valuable by-product from the production of palm biodiesel contains an abundance of natural phytonutrients such as carotenes, vitamin E, sterols, squalene and coenzyme Q. The present research described the concentration of phytonutrients that obtained from palm biodiesel production. The concentration of phytonutrients available in palm phytonutrients concentrate is ten times higher than in crude palm oil. … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 9,585 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharacterization of the Fracture Toughness of the Concrete Mortars Exposed to Elevated TemperaturesS. Djaknoun, A. Ahmed Benyahia, E. OuedraogoThe main objective of this research was the characterisation of the fracture toughness of concrete mortars exposed to high temperatures by using notched specimens in three point bending tests. The specimens have different lengths and were heated at different temperatures ranging from room temperature up to 900°C. The experimental test results obtained are closed with those reported by the literature, … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 6,524 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Tomato Geometries and Air Temperature on the Drying Behavior of Plum TomatoM.S. Brooks, N.H. Abou El-Hana, A.E. GhalyThe drying behavior of plum tomatoes as affected by drying temperature and tomato pieces geometry was investigated. The tomato was cut into halves, quarters and eighths and dried at temperatures of 55 and 65°C. During drying, the moisture content followed an exponential decay curve with R2>0.98. The time required to achieve the critical moisture content for storage (15%) for the … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,104 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of the Detoxification on the Shrinkage Temperature and pH of Chromium Leather Waste, Another Promising Way for the Tannery PollutionA. Malek, M. HachemiThe leather tannery industry produces a significant amount of solid chromium waste. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. This research describes the possibility of decrease of the shrinkage temperature and to increase the pH value of leather waste by detoxification treatment with use of tartrate … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,114 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Study of the Temperature Separation in the Ranque-Hilsch Vortex TubeSaeid Akhesmeh, Nader Pourmahmoud, Hasan SedgiThis research has been carried out in order to provide an understanding of the physical behaviors of the flow variation of pressure and temperature in a vortex tube. A computational fluid dynamics model is used to predict the flow fields and the associated temperature separation within a Ranque-Hilsch vortex tube. The CFD model is a steady axisymmetric model (with swirl) … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,316 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Storage Time and Temperature on Serum AnalytesAbdoljalal MarjaniInformation on the measured concentration of serum analytes during storage of serum samples is often incomplete and sometimes contradictory. The 10 analytes have not studied in this area in healthy subjects. The aim of present study was designed to determine the effect of storage time and temperature on the laboratory results of 10 analytes in sera from apparently healthy adult … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,870 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemoval of Dye from Textile Wastewater Using Plant Oils Under Different pH and Temperature ConditionsA.S. Mahmoud, Abdel E. Ghaly, M.S. BrooksThe effectiveness of five plant oils (cottonseed, olive, canola sunflower and used cooking oil) for the removal of dye from textile wastewater was evaluated. The study revealed that the dye removal efficiency increased as the temperature was increased. Under low pH, both the oil and dye split into two components each. Neither one of the oil components joined with either … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 8,351 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDFCite
