Research ArticleOpen accessEvery word in the titlePresents Some Aspects Related to the Atom and Atomic Electrons, Necessary in Understanding Chemical Bonds and NanotechnologiesFlorian Ion Tiberiu PetrescuThe paper presents briefly some aspects regarding the atom and its electrons, these being absolutely necessary for understanding the molecular bonds and future nanotechnologies. It is briefly presented how to determine the energies of the atomic electrons, their speeds of movement in the atomic orbit but also of rotation around a proper axis of the atomic electron, the kinetic energies … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 24 May 2020 · 7,245 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFinite-Element Numerical Simulation of the Bending Performance of Post-Tensioned Structural Glass Beams with Adhesively Bonded CFRP TendonsChiara Bedon, Christian LouterIn this study, a Finite-Element (FE) numerical investigation is carried out on laminated glass beams with Carbon Fibre Reinforced Polymer (CFRP) adhesively bonded post-tensioning tendons. Taking advantage of past four-point bending experimental test results available in literature, a refined full 3D FE numerical model is calibrated and validated. A key role is given to a multitude of aspects, including the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,744 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDuctility Behavior Fiber Reinforced Concrete Beams Strengthened With Externally Bonded Glass Fiber Reinforced Polymer LaminatesMariappan Mahalingam, Ragunath Pulipakka Narashima Rao, Suguna KannanThe study presents the results of an experimental investigation conducted on Steel Fiber Reinforced Concrete (SFRC) beams with externally bonded Glass Fiber Reinforced Polymer (GFRP) laminates with a view to study their strength and ductility. A total of ten beams, 150×250 mm in cross-section were tested in the laboratory over an effective span of 2800 mm. Three fiber reinforced concrete … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 24 Feb 2013 · 6,931 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStrength Modeling of Reinforced Concrete Beam with Externally Bonded Fibre Reinforcement Polymer ReinforcementN. Pannirselvam, P.N. Raghunath, K. SugunaThis research study presents the evaluation of the structural behaviour of reinforced concrete beams with externally bonded Fibre Reinforced Polymer (FRP) reinforcements. Three different steel ratios with two different Glass Fibre Reinforced Polymer (GFRP) types and two different thicknesses in each type of GFRP were used. Totally fifteen rectangular beams of 3 m length were cast. Three rectangular beams were … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,485 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMolecular Interaction Studies of H-Bonded Complexes of Benzamide in 1,4-Dioxan with Alcohols From Acoustic and Thermodynamic ParametersAN. Kannappan, R. Kesavasamy, V. PonnuswamyThe ultrasonic velocity, density and viscosity measurements were carried out for the mixtures of benzamide with Propan-2-ol, butan-1-ol, 1-pentanol and n-hexanal in 1,4-dioxan at 303, 308 and 313K. The derived acoustic and thermodynamic parameters namely adiabatic compressibility, free length, free volume, internal pressure, viscous relaxation time and Gibbs free energy were evaluated with a view to investigate the nature of … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,283 accessesView PDFCite
