Research ArticleOpen accessEvery word in the titleDevelopment of Ionizing Radiation Sensors Based on Carbon NanotubesKenneth Fontánez, Abraham García, María del C Cotto-Maldonado et al.SWNTs have been efficiently grown on patterned substrates, for its subsequent application to the development of ionizing radiation sensors. SWNTs before and after exposure to X-rays were characterized by Raman and XPS spectroscopy, revealing the appearance of alterations that have been justified as possibly due to the presence of adsorbed oxygen species. These materials have been used for the fabrication … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 29 May 2019 · 7,191 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRadiometric Invariant Dense Disparity Estimation for Real Time Stereo CorrespondenceDeepambika V. A., M. Abdul RahimanComputer stereo vision tries to mimic human vision by grabbing multiple views of the same scene and cognizing it. The stereo correspondence will find out the matching pixels between the two views based on the Lambertian criteria, which results in disparity. The distance of the objects from the camera can be calculated using this disparity. But in the real world … …Journal of Computer Science, Vol. 15, Issue 4 · 11 Apr 2019 · 7,228 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimizing Software Effort Estimation Models Using Back-Propagation Versus Radial Base Function NetworksAbdel Karim BaarehSoftware development effort estimation becomes a very important and vital tool for many researchers in different fields. Software estimation used in controlling, organizing and achieving projects in the required time and cost to avoid the financial punishments due to the time delay and other different circumstances that may happen. Good project cost estimation will lead to project success and reduce … …Journal of Computer Science, Vol. 15, Issue 3 · 11 Mar 2019 · 7,464 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCluster Based Architecture for Cognitive Radio NetworkManoj Ramachandran, Harish Sheeranalli Venkatarama, Sandesh HebbarCatastrophic events like flood often result in the derangement of the communication networks. The consequences include difficulty in locating the survivors of the disaster. The purpose of this paper is to give an insight to the design and development of a Cognitive Radio Network that can be used as an immediate remedy communication network which can help in such situations. … …Journal of Computer Science, Vol. 15, Issue 1 · 12 Dec 2018 · 7,711 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTaxifolin Potently Diminishes Levels of Reactive Oxygen Species in Living Cells Possibly by Scavenging Peroxyl RadicalsSatoru Sakuma, Yui Kishiwaki, Mayu Matsumura et al.Taxifolin, a naturally occurring dihydroflavonol, has been reported to possess antioxidant activity, whereas there is little information regarding its antioxidant potency as a flavonoid. In the present study, the antioxidant efficacy of taxifolin in living cells was compared to that of catechin, a potent radical scavenger, by using flow cytometry with the redox-sensitive fluorescent dye, 2′,7′-dichlorodihydrofluorescein diacetate. Further, diminishing efficacy … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 18 Oct 2018 · 8,056 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of Ultra Violet Radiation on Polyethylene Packaged Water Exposed at Varying Conditions: Are we Drinking Micro-Plastics?James Matthew Anayo, Victor Eshu Okpashi, Ikechukwu N.E. OnwurahThe public is worried about how their health is impacted by microplastics in sachet water. This awareness has repercussion for water producing factories and public health organization in managing health hazard associated with microplastic ingestion. Many countries in Africa, with concern to Nigeria, the act of packaging water in polyethylene materials by water producing factories has become accustomed. These packaged … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 29 Jan 2018 · 9,915 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExtracting the Potential Features of Digital Panoramic Radiograph Images by Combining Radio Morphometry Index, Texture Analysis, and Morphological FeaturesEnny Itje Sela, SutarmanOsteoporosis is a type of disease that is not easily detected visually. It contributes to bone fracture and so early diagnosis is particularly important to prevent bone fracture. An integrated approach for extraction of cortical and trabecular bone on the digital panoramic radiograph (DPR) images was proposed to screen osteoporosis. We performed radio morphometry index (RMI), texture analysis, and morphology … …Journal of Computer Science, Vol. 14, Issue 2 · 7 Dec 2017 · 8,026 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRadiological Risks Assessment of Ogun State Drinking WaterJustina Ada Achuka, Usikalu Mojisola Rachael, Oyeyemi Kehinde DavidThe presence of radionuclides in water constitute health risk to man. The consumption of such water increases the likelihood of incurring cancer. Analysis will enhance the detection of significant radionuclides causing harm to the populace and stimulate remediation. This inferred the radioactivity measurements of twenty (20) well water samples from three industrial cities of Ogun State using Hyper Pure Germanium … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 18 May 2017 · 7,785 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePotential Radiological Impacts of Phosphate Fertilizers Brands used in Southeast, NigeriaKenneth K. Agwu, Mark C. Okeji, Paschal TchokossaThe radionuclides present in phosphate fertilizers used in Southeast Nigeria were identified and their activity concentration determined to assess the potential radiological impact on the environment due to fertilizer applications in agricultural farm lands. The radioactivity concentration of 226Ra, 232Th and 40K in the fertilizer samples range from 13.22±1.83 to 87.37±8.98 Bqkg-1 for 226Ra (mean: 31.71±5.4 Bqkg-1), 0.78±0.07 to 47.65±6.05 … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 12 May 2017 · 7,480 accessesView PDFCite
