Research ArticleOpen accessEvery word in the titleFracture Initiation at the Zirconia/Veneer Interface-A Finite Element SimulationMirsayar M. M., A. T. SamaeiZirconia/veneer bilayered components are extensively used in dental restoration technology to improve resistance of tooth's surface from decay. The direction of the fracture propagation at the interface of zirconia and veneer is investigated in this study. Finite element analysis is performed on a bi-material four point bend specimen in different geometries and the fracture initiation angle is obtained using Maximum … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 8 Jun 2015 · 7,567 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsBonding of Resin Materials to All-Ceramics: A ReviewLiang Chen, Byoung In SuhProblem statement: All-ceramic materials, especially silica-based lithium disilicate and non-silicate-based Zirconia, have become a topic of interest in the field of dentistry. It is still difficult to achieve a strong and durable resin-ceramic adhesion, especially resin-Zirconia bonding. Approach: The article reviews the current literature published in the past 5 years, focusing on the latest resin bonding techniques (including surface treatment, … …Current Research in Dentistry, Vol. 3, Issue 1 · 21 May 2012 · 15,814 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsExperimental Investigation on Performance and Emission Characteristics of Low Heat Rejection Diesel Engine with Ethanol as FuelP. Lawrence, P. Koshy Mathews, B. DeepanrajProblem statement: Depleting petroleum reserves on the earth and increasing concerns about the environment leads to the question for fuels which are eco-friendly safer for human beings. The objective of present work was to investigate the effect of coating on piston, cylinder head and valves of a Diesel engine on the performance and emission characteristics of exhaust gases using wet … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,219 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSurface Bioactivity of Sol Gel Derived 3Y-TZP Bioinert Ceramic through Hydroxylation Technique Using 5M H3PO4R. Velmurugan, S. Kanagesan, S. Jesurani, T. KalaivaniProblem statement: This study presented bone like apatite formation on yttria stabilized zirconia in Simulated Body Fluid (SBF) through hydroxylation technique. Approach: Sol gel route was used to prepare yttria stabilized zirconia. Then it was hydroxylated with 5M H3PO4 for formation of Zr-OH group. Moreover, the growth rate of calcium and phosphate on zirconia substrate was examined using simulated body … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,244 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWood and Shrub Dwelling Pentatomidae (Heteroptera) of Rotected Areas of South-Eastern KazakhstanMeruyert Baizhunis, Perizat Esenbekova, Gulshat Anarbekova, Laszlo OrlociA biodiversity inventory of the woody of five families protected areas of the Charyn SNNP. The research revealed 30 species of predatory hemipterans from 5 families: Nabidae (4 species), Anthocoridae (12 species), Reduviidae (3 species), Miridae (5 species), Pentatomidae (6 species). According to trophic specialization, they are zoophages. According to the number of generations per year, they are divided into … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 8 Sep 2021 · 6,304 accessesView PDF Cite
