Research ArticleOpen accessIn the abstractPre-Reinforcement Sprinkle FRP for Reinforced-Concrete Beams against Earthquakes, FRP: Consumption in Civil EngineeringMoein Zargar, Hossein Gholami, Hossein Norouzi et al.Nowadays, the reinforcement is used by green concrete, coated steel sheet, reinforcement, fiber reinforced such as carbon, aramid, and glass as earthquake reinforcement methods for concrete structures. regard the reinforcing structures and buildings against earthquake forces in the future, only simple methods for lowering prices should not be considered and the earthquake behaviors should be completely transparent. In this article, … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 26 Jun 2019 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Study on Coupling Beam Retrofitted Using CFRP and GFRP SheetsSaeideh Hakimi, Rahmat MadandoustOne of the most useful way to resist against earthquake is using coupling beam of steel shear walls. The steel shear wall’s behavior depends on several factors such as stiffness, ductility, strength and so on. But, it has the shear cracks in coupling beam. In this paper, the effect of Carbon Reinforced Fiber Polymer (CFRP) on coupling beams has been … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 6 Aug 2018 · 7,723 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Study of Reinforced Concrete Beams Strengthened by FRP Bars Subjected to Impact Loading ConditionsSajjad Roudsari, Sameer Hamoush, Sayed Soleimani et al.Civil engineers have considered Fiber Reinforced Polymer (FRP) materials to enhance the performance of structural members subjected to static and dynamic loading conditions. However, there are some design limitations due to uncertainty in the behavior of such strengthened members. This fact is particularly important when considering the complex nature of the nonlinear behavior of materials, the impact loading conditions and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 9,929 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Expediency of the Preliminary Heat Treatment for Liquid-Phase Reduction of Waste Steelmaking SlagEvgeny Trofimov, Ilya Chumanov, Andrey Dildin, Olga SamoylovaThe problem of using waste steelmaking slags as a technogenic source of metallurgical raw materials still has no sustainable solution and requires innovative ideas and approaches. The purpose of this paper is a theoretical and experimental study of the possibility and expediency of the preliminary heat treatment of steelmaking slags in a reducing medium for greater metal recovery. The subject … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 26 Nov 2015 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractINFLUENCE OF REACTION TEMPERATURE AND REACTION TIME ON PRODUCT FROM HYDROTHERMAL TREATMENT OF BIOMASS RESIDUEJakaphong Kongpanya, Kanokorn Hussaro, Sombat TeekasapThailand is facing with problems associated with biomass residue such as palm oil residues (oil palm trunks, oil palm fronds, empty fruit bunches, shells and fibers). Biomass is promising source for the production of an array of energy-related produts including, liquid, solid and gaseous fuels, heat, chemicals electricity and other materials. Therefore, the use of biomass for energy is not … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 2 Jun 2014 · 7,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurface Modification of Mild Steel Using Tungsten Inert Gas Torch Surface CladdingS. Dyuti, S. Mridha, S. K. ShahaProblem statement: There is an increasing demand for claddings which possess an optimized combination of different functional properties such as high hardness, high resistance to wear and oxidation. In this respect, hard TiAlN cladding has gained much attention. These claddings can be suitable replacements for the conventional ceramic coatings applied in many components of chemical plants and automotive industries to … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,144 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrostructure Affecting Cutting Quality in Fine Blanking ProcessBopit BubphachotProblem statement: Fine blanking process is a high precision process and worldwide in developed countries. Since specimen does not occur fracture on the cutting edge and it is not necessary to decorate again in the finishing process for the fine blanking which can be reduced some operation steps. For example, if chain wheel of motorcycle is produced by conventional blanking, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractCementation Analysis by Eddy Current MethodM. Zergoug, H. Oubouchou, N. AmimeurIncrease the hardness, the endurance and the life time of material can be realised by surface treatments and remetallings, the electromagnetic properties of steels depend on their composition, their microstructures and constraints applied. We can use the electric and magnetic parameters to evaluate their microstructure. The object of this work is the characterization of cementation by the non-destructive methods and … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,565 accessesView PDFCite
