Research ArticleOpen accessIn the keywordsMass Spectrometry/Mass Spectrometry Study on the Degradation of B-Aflatoxins in Maize with Aqueous Citric AcidA. Méndez-Albores, I. Nicolás-Vázquez, R. Miranda-Ruvalcaba, E. Moreno-MartÍnezDegradation of B-aflatoxins in maize by means of 1N aqueous citric acid was confirmed by the AFLATEST immunoaffinity column method, High Performance Liquid Chromatography (HPLC), tandem mass spectrometry (MS/MS) and computational information. The AFLATEST and HPLC assays showed that 96.7% degradation occurred in maize contaminated with 93 ng g-1 when treated with the aqueous citric acid. Two major products, produced … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 8,049 accessesView PDFCite
Technical ReportOpen accessIn the abstractMagnetic Fusion Plasma DriveFlorian NeukartIn the evolving realm of space exploration, efficient propulsion methods are paramount to achieve interplanetary and possibly interstellar voyages. Traditional propulsion systems, although proven, offer limited capabilities when considering longer-duration missions beyond our immediate cosmic vicinity. This study introduces and thoroughly investigates the Magnetic Fusion Plasma Drive (MFPD) propulsion system, a novel fusion-powered propulsion mechanism. Through rigorous theoretical underpinnings and … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 4 Mar 2024 · 7,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractTechnical Buckling, Stress and Strain Simplified Analysis of Semi-Slender Thin-Walled Cylindrical Pinned ColumnKrzysztof MurawskiThe stability of load-bearing members is a challenging issue for designers. The avoidance of possible stability troubles is a mandatory step of the overall design process. The paper presents and discusses two simplified methods based on the Technical Stability Theory (TSTh) of loss of stability of lateral buckling in elastic-plastic states of semi-slender columns axially compressed by force. It is … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 27 May 2021 · 6,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation of Homomorphic Encryption for Wireless Sensor Networks Integrated with Cloud InfrastructureChristophe Ishimwe Ngabo, Omar El BeqqaliWith the current explosion of cloud services, it is easy for everyone to store the prodigious amount of data on remote servers. On the other hand, service providers are given full access to our information, or in the worst case, can be intercepted by malicious people. The solution is to encrypt the data to make it completely secret. But then, … …Journal of Computer Science, Vol. 15, Issue 2 · 8 Feb 2019 · 7,668 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Analysis of Spatial MechanismsFlorian Ion Tiberiu PetrescuThe paper briefly presents how structural analysis is performed on spatial mechanisms, presenting a practical application in the mechatronics of parallel robots, especially in Steward platforms. Structural analysis always helps to better understand the phenomena and especially the way the mechanisms are made. At spatial mechanisms the problems are a little more complex than those raised by plane mechanisms. For … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 7,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractInverse Kinematics of a Stewart PlatformRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The development and diversification of machines and mechanisms with applications in all fields require new scientific researches for the systematization and improvement of existing mechanical systems by creating new mechanisms adapted to modern requirements, which involve increasingly complex topological structures. The modern industry, the practice of designing and building machinery is increasingly based on the results of scientific and applied … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 10 Mar 2018 · 14,790 accessesView PDFCite
Review ArticleOpen accessIn the abstractMulti-Timescale Microscopic Theory for Radiation Degradation of Electronic and Optoelectronic DevicesDanhong Huang, Fei Gao, D.A. Cardimona et al.A multi-timescale hybrid model is proposed to study microscopically the degraded performance of electronic devices, covering three individual stages of radiation effects studies, including ultra-fast displacement cascade, intermediate defect stabilization and cluster formation, as well as slow defect reaction and migration. Realistic interatomic potentials are employed in molecular-dynamics calculations for the first two stages up to 100 ns as well … …Space Science International, Vol. 3, Issue 1 · 15 Jun 2015 · 10,235 accessesView PDFCite
