Research ArticleOpen accessIn the keywordsThe Study of the Dynamics of a Basic DoF RobotRelly Victoria Virgil PetrescuThe paper presents the study of the dynamics of a general DoF robot, highlighting some important new aspects in the dynamic design of a certain DoF robot. An improved method of positioning the robot in inverse kinematics is presented, then some new aspects in approaching the forces acting on a robot, but also regarding the determination of loads of the … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 16 Dec 2022 · 5,345 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Theory that Wants to Obtain Particles Opposite to Protons, Having a Negative ChargeRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe present paper focuses on the possibility of obtaining antimatter, in the main purpose of then extracting massive energy by controlled fusion of matter and newly obtained antimatter. Since the most well-known charged nucleon (of the matter) is the proton, we imagined another possibility to obtain a particle opposite to it, having the same main characteristics but the opposite charge, … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 11 Sep 2020 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContributions to the Hydrogen FusionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe issue of hydrogen fusion is an important one because once done it will generate enough energy for humanity, which is why the paper addresses some new ideas in this important but also necessary field. Attempts are made to make theoretical considerations modeled so that it can then help experimentally to put into practice the nuclear fusion of hydrogen, in … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,789 accessesView PDFCite
Review ArticleOpen accessIn the keywordsPermanent Magnetic FluidsNicolae Petrescu, Florian Ion Tiberiu PetrescuA team of researchers at the University of Massachusetts Amherst has accidentally obtained the first magnetized permanent liquid in the world, the droplets of this liquid moving in unison and able to associate in different forms while being manipulated exterior by means of a magnet, according to a new study published in the latest issue of the journal Science, reports … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 22 Aug 2019 · 8,848 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Geobacillus thermodenitrificans Lipase Activity and Binding Affinity by Acetone Treatment: Kinetic and in silico InvestigationsAmmar Khazaal Kadhim Almansoori, Alyaa Abdulhussein Alsaedi et al.Lipase Geobacillus thermodenitrificans (LipGt) is a thermostable enzyme that has an optimal activity temperature of 65°C. It can tolerate various organic solvents and has an improved activity, especially in the presence of acetone. In this study, in-vitro and in-silico studies were carried out to investigate the effect of acetone in enhancing the kinetic and binding affinity of LipGt. The LipGt … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 10 Oct 2024 · 4,821 accessesView PDFCite
Research ArticleOpen accessIn the abstractShelf-Life Prediction of Specialty Coffees using the Arrhenius ModelFrank Fernández Rosillo, María Alina Cueva Ríos, Lenin Quiñones Huatangari, Carla Guianella Samaniego LalanguiThe study estimated the shelf life of roasted and ground specialty coffees in bi-laminated and tri-laminated packaging concerning cup score, using the Acceleration Test at temperatures of 40, 50, and 60°C. The sensory evaluation was carried out by Q Grader tasters. Based on the higher value of the coefficient of determination of the regressions resulting from the cup and temperature … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 23 Dec 2022 · 6,885 accessesView PDFCite
Research ArticleOpen accessIn the abstractOne can Achieve the Nuclear Fission Reaction of Lithium by Accelerated Hydrogen Nuclei or NeutronsRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe idea circulated among physicists that in the upper area of the physical elements the fission reaction can be obtained and in the lower one the fusion reaction occurs. In the presented paper we want to impose another rule, namely the obtaining in the lower part of the physical elements of the fission and fusion nuclear reactions, with the obvious … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 7 Sep 2021 · 9,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of ZnO Nano Rods for the Batch Adsorption of Cr(VI): A Study of Kinetics and IsothermsSushma Kamath, Venu Gopal Vishwakarma Ramanjaneyalu, Susmita KamilaThe present study reports the synthesis of nano Zinc Oxide (ZnO) and its adsorption behaviour. The ZnO obtained by precipitation method were found to be well-defined nano rods arranged like flower. The shape, size and structure of ZnO were characterized from X-Ray Diffraction (XRD), Energy Dispersive X-ray (EDX) and Scanning Electron Microscope (SEM) analysis. These nano rods were utilized for … …American Journal of Applied Sciences, Vol. 16, Issue 3 · 12 Apr 2019 · 8,077 accessesView PDFCite
