Research ArticleOpen accessIn the abstractMATERIAL PARAMETER OF RUBBER GLOVE VULCANIZED USING COMBINED INFRARED AND HOT-AIR HEATINGTipapon Khamdaeng, Numpon Panyoyai, Thanasit WongsiriamnuayVulcanization is an important chemical-thermal process in production of rubber products resulting in change of material properties, increased elasticity and strength. In general, Young’s modulus is used as an indicator of elastic deformation at loading configuration. However, rubber is not truly elastic and a single parameter is insufficient to describe the whole deformation contributed by microstructure of rubber network. Therefore, … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 8 Feb 2014 · 7,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegumming of Raw Silk Fabric with Help of Marine Extracellular ProteaseDas Sumana, Mathummal Sudarshan, Ashoke Ranjan Thakur, Shaon RayChaudhuriProtease secreting microbe was isolated and characterized on the basis of their morphological, biochemical, physiological and 16S rDNA based molecular properties. The extracellular protease was quantified and characterized. Protease was used for different time (4, 8, 12 and 24 h) at different temperature (RT and 37°C) for optimization of the degumming process for raw silk fabric with enzyme dosage (0.2-1 … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Mechanical Properties of Aluminium Alloy 2024 Reinforced with Silicon Carbide and Fly Ash Hybrid Metal Matrix CompositesM. Mahendra Boopathi, K.P. Arulshri, N. IyanduraiMaterials are frequently chosen for structural applications because they have desirable combinations of mechanical characteristics. Development of hybrid metal matrix composites has become an important area of research interest in Materials Science. In view of this, the present study focuses on the formation of aluminium-Sic-fly ash hybrid metal matrix composites. The present study was aimed at evaluating the physical properties … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 8 Mar 2013 · 28,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of Fly Ash Based Coconut Fiber CompositeK. Saravana Raja Mohan, P. Jayabalan, A. RajaramanThe present paper reports the results of a study undertaken in enhancing properties of fly ash concrete composites-FMCC with locally available natural fiber. In this context a composite with fly ash, concrete and treated coconut fibers-available in plenty in rural areas of India-can be a good proposition and with this background, experimental investigation to study the effects of replacement of … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 20 Feb 2012 · 9,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractBonding Property of Bituminous Crack Sealants in the Presence of WaterEllie Fini, Taher Abu-LebdehProblem statement: Crack sealing and filling is the most widely used maintenance activity for in-service pavements. If an appropriate sealant material is selected and properly installed at the appropriate time of the pavement life, it retards pavement deterioration and increases its service life at a relatively low cost. However, in some cases it is reported that sealants failed prematurely, mainly … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,338 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlexural Behaviors of Damaged Full-Scale Highway Bridge Girder Strengthened by External Post TensionSayan Sirimontree, Jaruek TeerawongProblem statement: Prestressed Concrete (PC) I section girder with Reinforced Concrete (RC) topping slab has been widely applied to long span bridge girders for several years. A bridge girder is subjected to severe conditions caused by an aggressive environment and overloading. A crack can be initiated and propagate when the tensile stress exceeds the tensile strength of concrete due to … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Polypropylene-Clay Composite Using Carbon Nanotubes as Secondary FillerSalawudeen T. Olalekan, Suleyman A. Muyibi, Qasim H. Shah et al.Problem statement: Current researches have shown that the thermoplastic-clay nanocomposites have failed to live up to the earlier predictions albeit they have found some niche area of applications. This research work therefore aimed at studying the effect of carbon nanotube as secondary filler on the mechanical properties of polypropylene-clay nanocomposite. Approach: Hybrid polypropylene-clay nanocomposite was prepared in the presence of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,668 accessesView PDFCite
Research ArticleOpen accessIn the abstractPullout Characterizations of Various Steel Fibers Embedded in Very High-Strength ConcreteSameer Hamoush, Taher Abu-Lebdeh, Toney Cummins, Brian ZornigProblem statement: There is a real need for a fundamental understanding of bond and bond mechanisms in the newly developed Very-High-Strength-Concrete (VHSC) materials. The interfacial steel fiber/VHSC matrix bond tests are needed to characterize VHSC and to aid in the development of analytical models that describe bond behavior of this new material. Approach: This research investigated bond-slip characteristics of four … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractInjection Molding of Titanium Alloy Implant For Biomedical Application Using Novel Binder System Based on Palm Oil DerivativesR. Ibrahim, M. Azmirruddin, M. Jabir et al.Problem statement: Titanium alloy (Ti6Al4V) has been widely used as an implant for biomedical application. In this study, the implant had been fabricated using high technology of Powder Injection Molding (PIM) process due to the cost effective technique for producing small, complex and precision parts in high volume compared with conventional method through machining. Approach: Through PIM, the binder system … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Trujillo Algorithm for Analyzing of StructuresH. Hashamdar, Z. IbrahimProblem statement: The Trujillo algorithm is indirect method and has been used in this study. The approach is based upon the principle of conservation of energy.
