Research ArticleOpen accessContributions 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 · 6,784 accessesView PDF Cite

Research ArticleOpen accessInteraction between an Electron and a Quark DownRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe paper briefly studies the interaction between an electron and a down quark, considered integrated within a proton. It is therefore assumed that there is a down quark within a proton in which there are also two quarks up and an accelerated electron capable of penetrating the down quark inside the proton, in extremely difficult conditions in which the proton … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,954 accessesView PDF Cite

Review ArticleOpen accessAbout GatewayRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuAfter several postponements or even giving up, NASA finally decided to prepare and launch the long-delayed Moon space station Gateway, which had to be postponed for financial, technical reasons, but also for reasons and calculations about the possibility of assembling it in space and the way of transporting the main components in space, the main problem being the rockets capable … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 24 May 2020 · 6,205 accessesView PDF Cite

Research ArticleOpen accessKinematic and Dynamic Analysis of a Classic, Three-Axis Manual Gearbox, Without a Direct SocketRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuFixed axis mechanical transmissions today have the largest spread on the entire planet, being practically used in almost all areas. From the gearboxes of the vehicles to the stationary reducers, used in the electrical, electronic and electro technical equipment, in the heavy industry but also in the light industry, in energy and in transport, practically the transmissions with fixed axes … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 24 May 2020 · 7,673 accessesView PDF Cite

Review ArticleOpen accessProper Management of Planetary Hydrocarbon ResourcesFlorian Ion Tiberiu PetrescuMuch has been said about the planet's gas and oil resources and many assumptions and speculations have been made regarding their rapid depletion, but a report on the normal and judicious management of these important planetary resources for both energy and other various materials that are obtained today from them, such as composites, synthetic fibers for fabrics, plastics, rubber produced … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 24 May 2020 · 7,254 accessesView PDF Cite

Research ArticleOpen accessPresents Some Aspects Related to the Atom and Atomic Electrons, Necessary in Understanding Chemical Bonds and NanotechnologiesFlorian Ion Tiberiu PetrescuThe paper presents briefly some aspects regarding the atom and its electrons, these being absolutely necessary for understanding the molecular bonds and future nanotechnologies. It is briefly presented how to determine the energies of the atomic electrons, their speeds of movement in the atomic orbit but also of rotation around a proper axis of the atomic electron, the kinetic energies … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 24 May 2020 · 7,241 accessesView PDF Cite

Research ArticleOpen accessWhat is Better for Fusion?Florian Ion Tiberiu PetrescuIt is commonly considered that on earth, the fusion reaction could be started more simply if deuterium or more recently tritium, i.e., hydrogen isotopes 2 and 3, are used because they have a larger (and also atomic) nuclear mass and they will be easier to break down and then merge to obtain nuclear energy through fusion. In the present work, … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 14 May 2020 · 6,994 accessesView PDF Cite

Research ArticleOpen accessPresents the Dynamics at a Basic Anthropomorphic RobotRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuSerial robots are the most used today and among them, the most common is the basic 3R module, the module that is developed in the vast majority of anthropomorphic serial industrial robots, which today occupies at least 80-90% of the total industrial robots existing worldwide. One studied the kinematics and the forces in this module in other works, with an … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 5 May 2020 · 7,178 accessesView PDF Cite

Research ArticleOpen accessAbout Aircraft's New Power and PropulsionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuEven though the current classical methods of aerospace propulsion are much improved, some of the most modern methods have already been introduced, including propulsion with electric motors. Energy can be obtained from hydrogen burners, honeycomb burners to protect the combustion of hydrogen that burns 10 times faster than conventional fuels or alcohols. Hydrogen storage is also done in honeycomb cell … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 5 Mar 2020 · 7,325 accessesView PDF Cite

Review ArticleOpen accessPresents some Biologically Structured MaterialsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuIn this paper bio-tissue, mathematical modeling serves as a central repository to interface design, simulation and tissue fabrication. Finite element computer analyses will be used to study the role of local tissue mechanics on endochondral ossification patterns, skeletal morphology and mandible thickness distributions using single and multi-phase continuum material representations of clinical cases of patients implanted with the traditional protocols. … …OnLine Journal of Biological Sciences, Vol. 20, Issue 1 · 28 Jan 2020 · 7,046 accessesView PDF Cite
