A Heuristic Point of View on the Breathing in the Corona Virus Environment – a Review

Authors: Emanuel Gluskin
Comments: 15 Pages. It is an investigation related to human health

It is a mini-review of a study related to the breathing of a human having the corona virus disease. The motivating arguments and two essential results of the "macroscopic" analysis are carefully discussed. The weak points of the formal constructions are stressed in order to encourage a teacher to suggest good topics (some of which are formulated here) for students' projects, which creates some pedagogical slant.

A Brief Motivation for Electric High-Thrust Propulsion in General; and in Particular for the Plasma Propulsion Concept “Helios”

Authors: Danny Kirmse, U. Eschrich
Comments: 21 Pages.

The journey to the planets and maybe to the stars one day is an old dream of the humankind; to leave mother earth and dare the next, the interplanetary, step of exploration. “Dare mighty things” is a key slogan of these days of Percy’s arrival on the red planet. And this it is, space travel is still the great adventure of our days. Almost everybody, who is involved in space travel related activities, is passionate and enthusiastic and knows that she or he is part of something huge. Several technologies and research topics are part of space travelling. One cannot distinguish between the importance of the different involved technologies. But though, the basis and the origin of this journey is called propulsion. So, propulsion may not be more important than other technologies; but it is the fundament. And without propulsion there is basically no space exploration thinkable. For this reason, the following pamphlet is supposed to reflect the basic of propulsion in a rather naive way, which is more focusing on understanding the simple relations than to serve scientific wording. The further purpose is to derive from these relations a necessity of a very specific type of propulsion; the continuous electric high-thrust propulsion.

On the Structure of the Force Field in Electro Gravitational Vacuum

Authors: Sergey G. Fedosin
Comments: 14 Pages.

Analysis of the field equations for the tensors of the mass and charge components of the general field shows that their source is the charge four-current. In this connection, an assumption is made that it is the charge component of the force field of the electrogravitational vacuum in the form of fluxes of charged particles within the framework of Le Sage's theory of gravitation, which is mainly responsible for both electromagnetic and gravitational interactions, as well as for the action of other fields inside bodies. The parameters of the vacuum’s charged particles can be determined quite accurately using the theory of similarity within the theory of infinite nesting of matter, so that the description of the cause of emergence of electromagnetic and gravitational forces is filled with specific content.

¿Invariante Cuántico en Gravitación Newtoniana? (Quantum Invariant in Newtonian Gravitation)

Authors: Carlos Alejandro Chiappini
Comments: 8 Pages. [Corrections made by viXra Admin to conform with the requirements on the Submission Form]

Newton pidió ser disculpado `por presentar solamente la ecuación de la fuerza gravitatoria, sin explicar la naturaleza y el origen de la gravitación. Dijo que dedicó mucho esfuerzo al tema sin resultados convincentes y que, por ese motivo, prefirió dejar la terea para generaciones futuras. Ejemplo de honestidad y de lucidez. Veremos en este documento que esa fórmula es hoy la puerta de ingreso a un ámbito donde las preguntas tienen respuestas estimulantes.

Newton asked to be excused for presenting only the equation of the gravitational force, without explaining the nature and origin of gravitation. He said that he devoted a lot of effort to the subject without convincing results and that, for that reason, he preferred to leave the task for future generations. Example of honesty and lucidity. We will see in this document that this formula is today the gateway to an area where questions have stimulating answers.

The Projection Theory: an Approach to the Theory of Everything

Authors: Norbert Buchholz
Comments: 44 Pages. norbert.buchholz@kabelmail.de [Corrections are made by viXra Admin to comply with the rules of viXra.org]

This paper is divided into two main sections. In Part I, which is the subject of this publication, the fundamentals of the projection theory and the insights and calculation possibilities resulting from this new concept are presented (see Abstract). In part II, based on the findings in part I that protons and neutronsare not spherically symmetric but cubic particles, a new concept for the structure of atomic nuclei is presented which has nothing to do with quarks and gluons but is based on classical ideas.Part II will be published at a later date in the "Nuclear and Atomic Physics" section.

Aerosol Transport by Turbulent Continua

Authors: Rolf Warnemünde
Comments: 28 Pages.

The stochastic transport equations, derived rigorously under the condition of continnum uctuations in the framework of an ensemble theory, both in dierential and integral form, are then veried by establishing an unambiguous connection between this stochastics and the associated deterministics.
