Ruggero Maria Santilli. Apparent Nuclear Transmutations without Neutron Emission Triggered by Pseudoprotons
No full textAbstract: In this paper, we review the work by Don Carlo Borghi and R. M. Santilli on the laboratory synthesis of the neutron from the proton and the electron under the laws of hadronic mechanics. We then review the prediction of a subsequent synthesis, this time, of the neutron and the electron into a new particle, known as Santilli pseudoproton, which has essentially the same characteristics of the neutron except being negatively charged. We then outline, apparently for the first time, ongoing research on esoenergetic nuclear transmutations without neutron emission that are triggered by a flux of Santilli pseudoprotons
Hyperstructures in Lie-Santilli Admissibility and Iso-Theories
No full textIn the quiver of hyperstructures Professor R. M. Santilli, in early 90'es, tried to find algebraic structures in order to express his pioneer Lie-Santilli's Theory. Santilli's theory on 'isotopies' and 'genotopies', born in 1960's, desperately needs 'units e' on left or right, which are nowhere singular, symmetric, real-valued, positive-defined for n-dimensional matrices based on the so called isofields.These elements can be found in hyperstructure theory, especially in -structure theory introduced in 1990. This connection appeared first in 1996 and actually several -fields, the e-hyperfields, can be used as isofields or genofields so as, in such way they should cover additional properties and satisfy more restrictions. Several large classes of hyperstructures as the P-hyperfields, can be used in Lie-Santilli's theory when multivalued problems appeared, either in finite or in infinite case. We review some of these topics and we present the Lie-Santilli admissibility in Hyperstructures
Heston model: shifting on the volatility surface
No full textFitting the implied volatility surface is generally a complicated affair. Here Claudio Pacati, Roberto Renò and Manola Santilli propose a simple extension of the Heston model that allows fast and arbitrage-gree interpolation of the volatility surface with just one time dependent parameter
Antiprotons or pseudoprotons?
No full textThe author, an undergraduate physics student, reviews in this paper: 1) positive mass negative charge antiprotons according to 20th cen- tury particle physics; 2) positive mass negative charge pseudopro- tons according to hadronic mechanics; 3) the notion of antiprotons according to the isodual theory of antimatter; 4) a theorem recently proved by R. M. Santilli essentially implying that, under the spinorial Poincare ́ symmetry, the 20th century conjugation from particles to an- tiparticles prohibits partlcle-antiparticle annihilation into light; and 5) consequential doubts on the recent gravity test for the anti-hydrogen atom. Therefore, the author examines the possibility that antiparti- cles are actually gravitationally rejected by matter and 20th century antiprotons are in reality pseudoprotons with a consequential number of intriguing open problems in antimatter, like the astrophysical ori- gin of true antiprotons from cosmic rays, and others. We conclude by examining: the 1994 proposal for a resolutory test on the gravity of true antiparticles, such as the positrons; the possible existence of antimatter bodies in the universe which originate cosmic antiprotons; and related aspec
Estudio de la Isotopología de Tsagas-Sourlas-Santilli
No full textSince his original proposal of 1978 to study Lie-isotopic and Lie-admissible liftings of conventional, local-differential Hamiltonian formulations of point particles, the physicist R. M. Santilli suggested the contribution of a new topology as the mathematical foundations for the representation of extended, nonspherical and deformable particles with conventional local-differential interaction plus new nonlocal-integral interation as occurring, for instance, in molecular valence bonds. A first isotopic lifting of the conventional continuity was introduced by the physicist J. V. Kadeisvili in 1992. In 1993 the mathematicians G. T. Tsagas and D. S. Sourlas built the topology proposed by Santilli within the context of isotopic mathematics defined over fields of conventional numbers. In the same year, Santilli constructed the fields isonumbers, namely numbers with a positive-definite but otherwise arbitrary multiplicative unit. As a necesary condition to achieve invariance of isotopic formulations under the action of their own time evolution group, Santilli extended in 1996 the topology of Tsagas and Sourlas to isofields whose unit is a sufficiently smooth and positive definite, but arbitrary integro-differential expression representing extended particles with local-differential and nonlocal-integral interations. This memoir is dedicated to the aparently first, comprehensive mathematical study and generalization of the Tsagas-Sourlas-Santilli isotopology and includes: a generalization of the Kadeisvili's isocontinuity; the identification of the broadest possible isofields and isomanifolds; the systematic study of the broadest possible isotopology; and other topics. It is hoped that the isotopology emerging from this study does indeed fulfill Santilli's original suggestion of constituting the foundations of mathematical, physical and chemical studies on isotopic representations of extended, nonspherical and deformable particles with local-differential and nonlocal-integral interactions.En 1993, Tsagas y Sourlas definieron una isotopología en el caso en el que la proyección de un levantado isotópico de los números reales en el nivel convencional no coincida con dicho conjunto, es decir, en el caso en que se está trabajando con un isocuerpo de los denominado por Santilli de primer tipo. el propio Santilli también trató, en 1996, el caso de una isotopología para los llamados isocuerpos de segundo tipo. El objetivo principal de este artículo es profundizar en el estudio de esta segunda construcción, teniendo en cuenta los trabajados mencionados anteriormente de Tsagas, Sourlas y Santilli. Hemos optado para ello por definir un isoorden en el isocuerpo construido y realizar una generalización de la isocontinuidad de Kadeisvili para icuerpos de segundo tipo
Lie-isotopic representation of stable nuclei I: Apparent insufficiencies of quantum mechanics in nuclear physics
No full textAbstract
In this paper, we recall the majestic axiomatic consistency of quantum me- chanics for point-like particles and electromagnetic waves in vacuum. By following the 1935 historical argument by A. Einstein, B. Podolsky and N. Rosen that quantum mechanics is not a complete theory, we identify a number of apparent insufficiencies of quantum mechanics in nuclear physics with particular reference to the lack of numerically exact representation in one century of nuclear data, the prohibition by Heisenberg’s uncertainty principle to represent the neutron synthesis from the electron and the pro- ton in the core of stars despite their extremely big Coulomb attraction and the ensuing inability to represent the nuclear stability. We then point out that the axiomatic origin of the indicated insufficiencies appears to be due to the representation of nuclear constituents as dimensionless particles, compared to the experimentally measured extended character of the charge distribution of protons and neutrons in conditions of partial mutual penetration within a nuclear structure, with consequential strong interactions of nonlinear, non- local and nonpotential. In the second paper, we attempt a resolution of the indicated insufficiencies with ensuing exact and invariant representation of the Deuteron data. In the third paper, we present a consequential representa- tion of nuclear stability with ensuing new means of recycling nuclear waste by nuclear power plants and other advances
Lie-isotopic representation of stable nuclei III: Exact and time invariant representation of nuclear stability
No full textAbstract
In the preceding two papers, we presented exact and time invariant represen- tations of stable nuclei via the Lie-isotopic branch of hadronic mechanics and showed the necessity for the results of lifting Heisenberg’s uncertainty principle for point-like particles into the isouncertainty principle of hadronic mechanics, also called Einstein’s isodeterminism, for extended nucleons in condition of mutual penetration. In this paper we present apparently for the first time: the treatment of protons and neutrons as isoparticles charac- terized by the isosymmetries and isorelativities of hadronic mechanics; the representation of all characteristics of the neutron at the nonrelativistic and relativistic levels as a hadronic bound state of an isoelectron and an isopro- ton; the identification of the density of the neutron in a way compatible with other experimental data; and the representation of nuclear stability despite the natural instability of the neutron and despite the extremely repulsive pro- tonic Coulomb forces. The main implications of the above studies are: 1) The prediction of novel means for the recycling of radioactive nuclear waste by nuclear power plants via new stimulated decays. 2) The possible return to the continuous creation of matter in the universe as a consistent way to explain the 0.782 MeV missing in the neutron synthesis. 3) The apparent confirmation of the historical reduction of all matter in the universe to pro- tons and electron
Experimental Investigation of the Laser Micro Drilling of Different Alloys by means of Nd:YAG Green Laser
No full textAbstract
Micro-machining have been subjected to an important develop in fabrication of components for informatics,
electronic, and mobile telephone systems. Now a day they have been having a significant development in many
strategic sectors like the mechanical, the chemical and the medical one. A lot of structures with dimension of few
microns like micro pumps, micro motors, micro systems for the DNA analysis have been realized during the last
ten years. The micromachining sector is potentially a strategic field in industry as actually occurs a big demand of
micro components. For such a reason the following work has been carried on. The behaviour of different metals
undergone to laser micro drilling varying the machining parameters has been studied in this work. The source used
for the experiments is a Nd:YAG Q-Switched green laser. Materials machined are AISI 304, WC, Titanium,
Inconel 718 and Brass. Machining parameters varied are: frequency and power of laser beam, focal lens length
and thickness of materials. After the drilling the micro-holes obtained has been observed with a scanning electron
microscope (SEM) with the aim of analyze their quality attributes. Quality attributes of the realized machining are:
radial and vertical spatter, tapering and dimensions of the holes. Experimentation has been carried out using the
method of design of experiment (DOE FACTORIAL). It is advantageous to realize micro-holes using a laser
because this alternative technology allows to realize machining without contact between piece and tool. Such a
machining permits also to reduce working time and to process materials very difficult to machine with other
technologies
Experimental confirmations of the new chemical species of Santilli MagneHydrogen
No full textAbstractIn this note, we report two different experimental confirmations of the new chemical species of MagneHydrogen (MH discovered by R. M. Santilli in 2003 [1]) with 99% Hydrogen content, but also having a multiple of the specific weight of conventional molecular Hydrogen. A number of features of the new species MH are pointed out, such as the increased energy content and the lack of seepage through the walls of a container. These features appear to be relevant for the Hydrogen industry. Samples of the new species of MH are made available at no cost to qualified chemists for independent verifications
