Research ArticleOpen accessEvery word in the titleNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,883 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDefect Classification of Reinforced Concrete Structures with Nondestructive Tests Using Statistical and Machine Learning MethodsSajjad Sayyar-Roudsari, Armaghan Shalbaftabar, Farshid Damirchilo et al.In this study, twelve reinforced concrete beams were constructed, each with specified dimensions and initial compressive strength. The beams were divided into four groups: A control group without any defect, a void group featuring a centrally located void, a corrosion group and a debonding group. The impact echo test was used for nondestructive testing, gathering data on compressive and shear … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 11 Jun 2024 · 5,258 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel Method for the Non-Destructive Assessment of Strength Degradation and Re-Use Potential of Weathered Float Glass From Facades: A Proof of Concept StudyFred Veer, Mauro Overend, Irene Sofokleous, Chris NoteboomLack of knowledge about the properties of weathered (used) glass is currently a major barrier to glass reuse. This results in probably unnecessary recycling or down-cycling of architectural glass at the end of life. Avoiding this creates a significant opportunity to reduce resource depletion and decarbonize the built environment. This can be done by developing an optical non-destructive test method … …International Journal of Structural Glass and Advanced Materials Research, Vol. 7, Issue 1 · 19 Oct 2023 · 9,292 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of Cement Kiln Dust on the Soil Electrical ResistivityHamid Ranjkesh Adarmanabadi, Arezou Rasti, Mehrdad RazaviElectrical resistivity is a non-destructive, cost-effective and sensitive method to evaluate soil's physical and chemical properties. Electrical resistivity has been used widely in surface and subsurface exploration. The electrical resistivity is directly related to the subsurface geotechnical and geothermal properties like porosity, temperature, salinity and water content. Recently uses of waste material as an additive to improve the soil engineering … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 14 Jan 2021 · 7,272 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Melatonin in Prevention of Neuropathy in STZ-Induced Diabetic RatsNasser Zangiabadi, Vahid Sheibani, Majid Asadi-Shekaari et al.Problem statement: Diabetes mellitus occurs mainly with chronic polyneuropathy, and oxidative stress plays an important role in emergence of most neurologic and behavioral changes in diabetic patients. Many studies have focused on the beneficial effects of various antioxidants such as melatonin on diabetic neuropathy. The aim of this study is to evaluate the effect of melatonin in prevention of neuropathy … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 2 · 17 Sep 2011 · 9,358 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Influence of the Climatic Factors on the Decay of Marbles: an Experimental StudyPaola Marini, Rossana BellopedeStone decay is affected by the influence of climatic factors. In particular marble degradation, that could be expressed by decohesion and /or bowing, is mainly due to the action of temperature and water (rains and relative humidity). In this work non destructive and destructive tests have been performed to evaluate the decay of marble slabs subjected both to natural exposition … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,123 accessesView PDF Cite
