Research ArticleOpen accessAll words, across the recordExperimental Investigation of Limonene-based Environmental-Friendly Emulsion Drilling MudOlaitan Oluwaseum Micheal, Orodu Oyinkepreye David, Ehinmowo Adegboyega BoluThe use of emulsion drilling mud in the oil and gas industry has gained wide acceptance. However, the disposal of drill cuttings and the waste of such emulsion drilling mud usually poses environmental concern. Hence, there is the need to seek oil from biodegradable sources as an alternative to the current conventional diesel oil which constitute environmental threat. In this … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 12 Jun 2017 · 7,923 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBehavior of Lightweight Coarse Aggregate RC Beams with Circular OpeningAdel A. Al-AzzawiThis pressent research investigates the mechanical properties of Waste Rubber Fibers Lightweight Coarse Aggregate Concrete (WRFLWAC) mixture. Also, the shear behaviors of 12 RC beams contain opening are investigated. The main study parameters are: The opening location, the waste rubber fiber ratio and the shear reinforcement. Deflection values and cracks are registered at each load step; also the cracking or … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 1 Apr 2017 · 7,453 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFractal Dimension for the Characterization of Asphalt Mixture PropertiesGiovanni LeonardiIn the design of asphalt mixtures for paved roads, the shape of solid elements has a great importance. In asphalt concrete, the shape of aggregate particles influences the resistance, durability, stiffness, fatigue response and the required binder content of the mixture. Fractal geometry is more suitable to describe the irregularity of the shape of aggregate particles. This paper describes the … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 13 Jul 2016 · 7,181 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Use of Nano Silica for Improving Mechanical Properties of Hardened Cement PasteIntisar Kuli, Taher M. Abu-Lebdeh, Elham H. Fini, Sameer A. HamoushThe influence of adding Nano particles of silicon dioxide (SiO2) on cement pastes was studied for both water and vacuum curing methods. Specimens made up of different percentage of Nano Silica were tested at different ages ranging from 3-56 days. The effect of (5-20 nm) Nano-Silica on the strength development of Nano-cement was determined using Material Tests System (MTS). The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 9,084 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordINVESTIGATING 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 accessAll words, across the recordSimplified Procedure for Unsaturated Flow ParametersNatthawit Jitrapinate, Vichai Sriboonlue, Kriengsak Srisuk, Dolrerdee HormdeeProblem statement: The unsaturated hydraulic conductivity K(θ) and Soil Water Characteristic Curve (SWCC) for saline soil or soil directly contacted with saline water are not permitted using several apparatus to determining. Approach: A simplified method to determine K(θ) and SWCC by using simple apparatus is presented. Using the proposed numerical model with the van Genuchten equations and inverse calculation for … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,828 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Garcinia Atroviridis on Oxidative Stress and Atherosclerotic Changes in Experimental Guinea PigsAdel. A. Amran, Zaiton Zakaria, Faizah Othman, Paden MoratProblem statement: Oxidative stress plays a major role in hypercholesterolemia induced atherosclerosis. Garcinia atroviridis has been shown to exhibit antioxidant properties. Approach: The present study aimed to investigate the effect of Garcinia atroviridis on the oxidative stress in guinea pigs fed with high cholesterol diet. Twenty-four male Guinea pigs were divided into four groups. Group I served as control while … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 9,035 accessesView PDFCite
