Research ArticleOpen accessIn the abstractInvestigating Effects of Application of Silica Fume to Reduce Asphalt Oxidative AgingNader Abutalib, Elham H. Fini, Sassan Aflaki, Taher M. Abu-LebdehThis paper investigates the feasibility of using silica fume to enhance the rheological properties of asphalt binder. It has been widely reported that asphalt binder oxidation is one of the phenomena that reduces the service life of asphalt pavement by negatively impacting its rheological properties. This in turn can lead to a more brittle pavement which is more prone to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 8,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractLaser-Induced Breakdown and Detonation in Particle-Laden SystemsKonstantin VolkovSimulation of the interaction of a laser pulse with gas-droplet and gas-particle mixtures plays an important role in environmental and engineering applications. The injection of liquid droplets or metal particle causes optical breakdown on the individual droplet or particle and leads to a drop of the detonation minimum pulse energy of the mixture. Mathematical models of various stages of the … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 4 Mar 2015 · 7,348 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATING EFFECTS OF INTRODUCTION OF CORNCOB ASH INTO PORTLAND CEMENTS CONCRETE: MECHANICAL AND THERMAL PROPERTIESAntonio Price, Ryan Yeargin, Ellie Fini, Taher Abu-LebdehThe purpose of this study was to evaluate the benefits of replacing Ordinary Portland Cement (OPC) with Corncob Ash (CCA) blended cements. The cement industry contributes considerable amount of Carbon Dioxide (CO2) emissions into the atmosphere. The main contribution of CO2 emissions from cement production results from the process of creating Calcium Oxide (CaO) from limestone (CaCO3) commonly known as … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 31 Mar 2014 · 9,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATING EFFECTS OF AMINE BASED MODIFIER ON RECYCLED ASPHALT SHINGLES BLENDINGGovinda Sedhay, Elham H. Fini, Taher Abu-LebdehA laboratory study was conducted to investigate the effects of Amine based modifier on rheological characteristics of particle filled viscous medium such as asphalt binder in presence of Recycled Asphalt Shingles (RAS). In this study, virgin asphalt binder (PG 64-22), three different percentages (20, 30 and 40%) of tear-off shingles and modifiers; Rediset, Evotherm and Bio-binder were used. The tear-off … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 26 Mar 2014 · 8,723 accessesView PDFCite
Research ArticleOpen accessIn the abstractDIFFERENT APPROACHES TO CRYSTALLIZATION OF MEMBRANE PROTEINSPrakash G. Doiphode, Vivek Pratap SinghCrystallography is more like an art than science. Crystallizing membrane proteins are a big challenge; membrane proteins are present in the cell membrane and serve as cell support. The most important feature of membrane protein is that it contains both hydrophobic and hydrophilic regions on its surface. They are generally much more difficult to study than soluble proteins. The problem … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 18 Dec 2012 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncorporation of Bentazone with Exserohilum rostratum for Controlling Cyperus iriaFranklin Ragai Kundat, Loo Hong Shen, Osumanu Haruna AhmedProblem statement: Various methods are used to counter the population of Cyperus iria in rice fields and among the most common method are chemical approaches. Chemical control methods are preferred by rice farmers due to their efficacy, speed, ease of storage and affordable cost. The concern of chemical herbicides is on its effects on the environment. Less attention had been … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 5 Sep 2011 · 9,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part II: Characteristic Velocity Profiles, Critical Loading and Binary CorrelationsV. S. Chok, A. Gorin, H. B. ChuaProblem statement: In Part I of this research, the main features of the fluidization behavior and characteristic velocities had been reported. Approach: In the present research, the mixtures characteristic velocity profiles for various sand sizes, palm shell sizes and weight percents were presented. It was recognized that there are instances where the characteristic values remain nearly unchanged from its pure … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,423 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption Study of Electric Arc Furnace Slag for the Removal of Manganese from SolutionC. L. Beh, Luqman Chuah, Thomas S.Y. Choong et al.Problem statement: Steel making slag from Electric Arc Furnace (EAF) is an abundant by-product in Malaysia steel making industry. It has potential to be used for heavy metal removal from contaminated water or waste water. Approach: The aim of this study was to investigate the characteristic and behavior of manganese removal by using EAF slag for efficient metal removal. The … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Production of Oligosaccharides by a Reaction using Whole Mammalian Cells as BiocatalystsTomohisa Kato, Rie Mitsumori, Kenichi HatanakaProblem statement: Mammalian cells were used for the production of oligosaccharides by saccharide primer method. However, because cells in culture are used, productivity of oligosaccharides is low. Approach: In saccharide primer method employing cells under culture, glycosylation was performed only by mixing the collected cells in reaction mixtures. Saccharide primer, 12-azidododecyl β-lactoside that mimics lactosylceramide (LacCer), was incubated with various … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,439 accessesView PDFCite
