Research ArticleOpen accessIn the abstractVulnerability and Protection of Glass Windows and Facades under Blast: Experiments, Methods and Current TrendsXihong Zhang, Chiara BedonGlass has been overwhelmingly used for windows and facades for modern constructions. Nevertheless, due to its relatively low tensile strength and mostly brittle behaviour, compared to other structural members, glass windows/facades are one of the most fragile components for a building envelop that are always associated with vast casualties in a blast incident. Several researches have been carried out to … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 24 Jul 2017 · 14,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Composite Beams Made of Steel Tubes Filled with Concrete under the Confinement Effect of U-Links and Stud-PlateMoayyad Al-Nasra, Madiha Ammari, Taher Abu-Lebdeh, Abdelqader NajmiConcrete strength improved substantially when lateral confinement stresses are provided. This effect has been exploited in this study in composite beams at the concrete compression zone. New type of confinement is used in this research. The confinement of concrete in the compression zone is accomplished by providing U-links and stud-plate systems. The U-links are steel bars in the shape of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractCross-Section Optimization of Sandwich-Type Cylindrical Wind Turbine TowersStylianos M. Vernardos, Charis J. GantesAs wind energy is aggressively expanding within the alternative sources' part of modern world's energy pie, the need of addressing various obstacles that limit further wind utilization becomes all the more urgent. From a structural engineering point of view, surmounting the tower-base diameter limitation, dictated by the current transportation capabilities, is one of the industry's primary issues. The concept presented … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 7 Aug 2015 · 7,993 accessesView PDFCite
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 abstractA Brief Tour into the History of Gravity: From Emocritus to EinsteinPanagiotis Papaspirou, Xenophon MoussasThe History of Gravity encompasses many different versions of the idea of the Gravitational interaction, which starts already from the Presocratic Atomists, continues to the doctrines of the Platonic and Neoplatonic School and of the Aristotelian School, passes through the works of John Philoponus and John Bouridan and reaches the visions of Johannes Kepler and Galileo Galilei. Then, the major … …Space Science International, Vol. 1, Issue 1 · 20 Jun 2013 · 15,084 accessesView PDFCite
Research ArticleOpen accessIn the abstractDyeability and Mechanical Properties of Acrylonitrile-Diallylamine Salts CopolymersAbir S. Abdel-Naby, Salha N. Al-HarthiThe dyeability of Acrylonitrile-Diallylamine Acetate (AN-DAA acetate) and Acrylonitrile-Diallylguanidine Acetate (AN-DAGA) copolymers have been studied with both conventional and ultrasonic methods. The results obtained were compared to the parent polyacrylonitrile. The effect of dye concentration, dye bath pH, dyeing time and temperature were studied and the results obtained by dyeing with both techniques were compared. Color strength values were found … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 31 May 2013 · 6,561 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrengths and Weaknesses of Digital Maturity ModelsAbdoulaye Sadio Barry, Saliha Assoul, Nissrine SouissiAssessing digital maturity is a prerequisite for any digital transformation initiative. This assessment allows the business to know its current level of digital maturity and assess its ability to manage change. The evaluation also enables society to identify the main thrusts and objectives of its digital strategy. This article analyses the strengths and weaknesses of 8 digital maturity models to … …Journal of Computer Science, Vol. 19, Issue 6 · 31 May 2023 · 6,962 accessesView PDFCite
EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,461 accessesView PDFCite
Technical ReportOpen accessAll words, across the recordSmall Hard Body Impact on Annealed, Heat Strengthened and Fully Tempered Laminated GlassFred Veer, Ton Romein, Pim BuskermolenNeglecting the accidental soccer or golf ball hitting the window of the neighbors in a movie, actual impact on glass is rare. In architecture, the only significant case in the literature is where a fully tempered laminated panel of the New York Apple cube was hit by a small stone launched by a snow blower. Nowadays a lot of glass … …International Journal of Structural Glass and Advanced Materials Research, Vol. 6, Issue 1 · 13 Jul 2022 · 10,561 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMulti-Objective Optimization of FRP Jackets for Improving the Seismic Response of Reinforced Concrete FramesCorrado Chisari, Chiara BedonIn this study, a multi-objective Genetic Algorithm (GA) optimization procedure is proposed for the seismic retrofitting of Reinforced Concrete (RC) building frames via Fiber-Reinforced Polymer (FRP) jackets. The optimization problem is solved via numerically efficient but accurate Finite-Element (FE) models able to take into account the strengthening and ductility increase contribution for a given FRP jacketing configuration. Based on a … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,825 accessesView PDFCite
