Research ArticleOpen accessIn the keywordsQuickest Multi-Commodity Flow Over Time with Partial Lane ReversalsTanka Nath Dhamala, Shiva Prakash Gupta, Durga Prasad Khanal, Urmila PyakurelRouting of more than one different commodity from specific origin nodes to the corresponding destination nodes through the arcs of an underlying network respecting the capacity constraints is one of the main problems in operational research. Among them, the quickest multi-commodity flow problem concerns with minimization of time taken to complete this process. The general multi-commodity and quickest multi-commodity flow … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 2 Oct 2020 · 7,311 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Water Bath Heating on Tannin Content and Quality Improvement Potential of Gambier (Uncaria gambir Roxb.)Daimon Syukri, Bastian Nova, Rina Yenrina et al.Gambir (Uncaria gambir Roxb.) is a source of natural phenolic compounds rich in catechins and tannins and has potential as a sustainable industrial raw material. During heating, phenolic compounds may undergo structural changes, including possible oxidation and polymerization, which can affect gambier quality beyond its catechin content. This study evaluated the effect of indirect heating duration using a water bath … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 715 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresenting a New Equation that Accurately Determines the Size of a Moving Elementary ParticleFlorian Ion Tiberiu PetrescuThe paper briefly presents a new Eq. (9). The role of Eq. (9) is to accurately determine the size of a moving elementary particle, depending on its velocity (or particle energy). Although Eq. (9) has a general character, it can be applied to any elementary particle in motion to determine the size of that particle, in the study, it was … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 24 Nov 2022 · 6,479 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOne 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 keywordsPresents 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 · 7,245 accessesView PDFCite
Research ArticleOpen accessIn the keywordsWhat 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 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Hypothesis Which Supports the Possibility of the Existence of Dark Matter with Negative MassFlorian Ion Tiberiu PetrescuThe paper presents an algorithm for calculating the negative mass of an atomic electron, a fact that from a physical point of view shows the possibility of the existence of the matter with the negative mass that could constitute the dark matter that separated from the normal matter with the positive mass due to the huge masses of different matter … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 23 Jan 2020 · 7,923 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 keywordsFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,781 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBoundary Distributions with Respect to Chebyshev's InequalityPeter Bias, Shawn Hedman, David RoseVariables whose distributions achieve the boundary value of Chebyshev’s inequality are characterized and it is found that non-constant variables with this property are symmetric discrete with at most three values. Nevertheless, the bound of Chebyshev’s inequality remains optimal for the class of continuous variables. …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 8,638 accessesView PDFCite
