Research ArticleOpen accessIn the keywordsSerial, Anthropomorphic, Spatial, Mechatronic Systems can be Studied More Simply in a PlanRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The mobile, mechatronic, robotic, serial, spatial, anthropomorphic type systems, which are currently the most used in the machine building industry, can be studied much more simply in a plan instead of the usual spatial study. This not only simplifies the understanding of these systems (including from a didactic point of view) but also facilitates computational methods, moving from matrix analytical … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 6,441 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThermodynamic Inference of the Antioxidant Process of Malic Acid and Its Structural AnalogsHan Wu, Wenhao Dong et al.Two structural analogs of Malic Acid (MA), 2-isopropylmalic Acid (2-IPMA), and 3-isopropylmalic Acid (3-IPMA) were recently identified and separated from wine. Although they have been shown to have antioxidant activity, the mechanism of their actions is still unclear. Antioxidant activities of 2-IPMA and MA were tested through DPPH, ABTS, and PTIO methods and the antioxidant-related thermodynamic properties were evaluated using … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 30 Oct 2024 · 4,824 accessesView PDFCite
