Research ArticleOpen accessPhrase in the titleUse of Surface Energy to evaluate Adhesion of Bituminous Crack Sealants to AggregatesEllie H. Fini, Imad L. Al-Qadi, Taher Abu-Lebdeh, Jean-Francois MassonProblem statement: The performance of bituminous sealants in the field is partly controlled by properties and strength of the sealant-aggregate interface. The thermodynamic work of adhesion represents energy required for reversible separation of the two materials at the interface. The study of fracture includes the energy required for both reversible and irreversible processes during separation. Excess of work of facture … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 7,889 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInvestigating Effects of Water Conditioning on the Adhesion Properties of Crack SealantAhmed Lamarre, Elham H. Fini, Taher M. Abu-LebdehThis paper investigates the effect of water exposure on three different crack sealants commonly used in cold, moderate and hot climates. It is hypothesized that water penetrates into the interface between crack sealant and substrates causing progressive adhesion failure and that the rate of failure varies depending on the sealant’s surface chemistry as relates to its interaction with water molecules … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 14 Mar 2016 · 8,783 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization of Biodiesel Production from Spent Palm Cooking Oil Using Fractional Factorial Design Combined with the Response Surface MethodologyS.M. Zakir Hossain, Nahid Sultana, Muhammad Faisal Irfan et al.Fractional Factorial Design (FFD) of the experiments combined with the response surface methodology was used to determine the optimum conditions for the production of biodiesel from Used Cooking Oil (UCO) in a batch reactor. Spent palm olein cooking oil was used as a raw material for biodiesel production as it is commonly used in most of the restaurants in Bahrain. … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 22 Nov 2016 · 8,446 accessesView PDFCite
Research ArticleOpen accessIn the keywordsElectrophysiology and Biopotential Issues on Human Electrocardiogram: A ReviewMahmoud Ahmed Suliman Ali, Xiao Ping Zeng, Guo Jun LiProblem statement: The heart is the first organ and most importantly to form in the body, where is found the most powerful generator of electromagnetic energy in the human body. Electrophysiology was the best method used to diagnose human heart problem. Knowledge of the electrical potentials in human heart was a quantum leap in the science of the human heart. … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 7,874 accessesView PDFCite
