Review ArticleOpen accessEvery word in the titleSeismic and Thermal Retrofitting of Masonry Buildings with Fiber Reinforced Composite Systems: A State of the Art ReviewArnas Majumder, Flavio Stochino, Fernando Fraternali, Enzo MartinelliOld masonry buildings represent the largest part of traditional constructions. Generally, they are both seismically vulnerable and thermally dispersive. Therefore, the need for seismic and thermal retrofitting aimed at reducing their vulnerability and environmental impact has motivated research efforts towards sustainable retrofitting solutions. This study presents a literature review of the approaches currently available for masonry retrofitting. Specifically, it highlights … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 22 Feb 2021 · 11,964 accessesView PDFCite

Rice hull is the by-product from rice processing that rich of dietary fiber content. The objectives of our study were to evaluate the effects of dietary fiber level from grounded rice hull on growth performance, nutrient digestibility, intestinal morphology and bacterial cell count in hindgut of weaning … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 1 · 28 Mar 2020 · 7,308 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWater Filter Fabrication from a Mixture of KMnO4 Modified Kapok Carbon Fiber, Zeolite, Bentonite and Clay for Fe3+Removal and Water Hardness TreatmentKannika Thongdee, Kalayaporn Parun, Suphakrit Benjatitmongkhon et al.A water filter was fabricated from a mixture of KMnO4 modified kapok carbon fiber, zeolite, bentonite and kaolinite clay for Fe3+ removal and water hardness treatment. The effects of amount of KMnO4 modified kapok carbon fiber (30-60 wt%), zeolite (20-40 wt%) and sintering temperature (500-700°C) on the properties of sintered products were evaluated. The best of sintered products were tested … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 15 Jun 2017 · 7,583 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleControl of Bubble Formation at the Optical Fiber Tip by Analyzing Ultrasound Acoustic WavesViacheslav Viacheslavovich Kazakov, Vladimir Isaakovich Yusupov, Viktor Nikolaevich Bagratashvili et al.The problems of controlling the processes of generation of acoustic waves and microbubbles at the optical fiber tip of moderate-power surgical lasers with wavelengths of 1.9 µm and 0.97 µm using active and passive acoustic methods are considered. It is shown that microbubbles of various sizes can be detected with an ultrasound method, in which the interaction area is recorded … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 2 Nov 2016 · 8,490 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKMnO4 Modified Carbon Prepared from Waste of Pineapple Leaf Fiber Production Processing for Removal of Ferric Ion from Aqueous SolutionSumrit Mopoung, Thaksaphon BuntermKMnO4 modified carbon materials from waste of pineapple leaf fiber production processing were prepared and characterized. The effects of % weight of KMnO4 (0-5 %wt) and carbonization temperature (500-700°C) were studied by SEM-EDS, XRD, FTIR and BET.
