Résumé :

The four basic fundamental physical forces that exist in nature are: weak nuclear force, strong nuclear  force,  electromagnetic  force,  and gravity. Out of all these forces, gravity is the weakest. It is a force that is always present. It pulls objects toward each other. It helped shape the universe. It also affects life on Earth. Newton’s law of gravitation is about how objects pull on each other. Every object in the universe attracts every other object. The force of this attraction

Résumé :

Abstract Introductory physics courses cover the gravitational and electromagnetic force in some detail, but the strong and weak nuclear forces are often given only a cursory treatment. This paper presents some ideas for teaching students about the strong force using practical hands-on demonstrations and using the strong force potential in teaching certain aspects of calculus. A good analogy to the strong force is to place a strong magnet on a metal whiteboard. The magnet must be very close to the board for the magnet to stick to the metal exemplifying the short range of the strong force. Anoth

Résumé :

We investigate two methods to include the strong nuclear force in hydrogenantihydrogen scattering calculations. First, we construct a model optical potential with parameters determined by the measured shift and width of the protonium ground state. Although this potential is a very crude model for the strong nuclear force, its parameters may be adjusted to reproduce both bound states and low-energy annihilation cross sections to within the experimental accuracy. It is then shown that this potential may be reduced to a short-distance boundary condition in terms of the protonantiproton strong-i

Résumé :

Abstract: This paper explores the relationship between motion, time, energy, and forces. It proposes a new framework based on the idea that motion drives time, energy, and forces. Without motion, it is impossible to perceive time, energy, or forces. Motion precedes time because time is created through motion. The concept of time without motion is meaningless. Furthermore, not only time but also all forms of energy and forces depend on motion. Energy is generated, changed, or transformed due to motion.

Résumé :

The origin of nuclear force is assigned to Coulomb interactions between quarks, u and d, in neighboring nucleons, replacing the current unspecified “residual” strong interaction assignment. The deuteron binding energy is correctly estimated using quasi-classical models for nucleons based upon SSI, the scalar strong interaction hadron theory. The next lightest nuclei are analogously treated. The Coulomb binding energies depend upon the small, in principle observable, internucleon distances between such u and d quarks whose positions in their respective host nucleons however depend upon intranuc

Résumé :

The unification of the four forces is the ultimate goal of physics. At present, humans have not really unified the power and the strong force, and the source of the strong force remains a mystery. In 2018, Liu Yun proposed a new formula to accurately calculate the static mass of particles. Later, Liu Ziyi assumed that the particle was composed of three charges with integer 1, and believed that the particle's high rate spin produced the strong force. According to Coulomb's law and relativity, he deduced the formula for the strong force coefficient between particles and Λc(2287), and found that

In search of the possible long range force between hadrons, S wave phase shift data of the proton-proton scattering are analyzed. In the analysis, the once subtracted Kantor amplitude is calculated, and the one-pion exchange contribution is separated. The remainder of the Kantor amplitude has a huge cusp at the threshold with the attractive sign. It is shown that such a cusp cannot be fitted by the spectral function of the twopion exchange, since it starts at [Formula: see text]. The cusp is fitted by a potential of the long range type with the asymptotic form of V(r) ~ −C/rα. After the chi sq

Why do atomic nuclei exist at all? A large nucleus contains many protons in close proximity. Why do these protons, all with the same electrical charge, not mutually repel? ‘Powerful forces’ shows the answer: a strong attractive force that acts between neutrons and protons when they are in contact with one another. Further studies of atomic structure have revealed that protons and neutrons are not fundamental particles. They consist of smaller particles: pions, which are made up of quarks that possess a ‘colour’ charge. The relativistic quantum theory of colour, known as quantum chromo-dynamics

In fact we encounter the characteristic phenomena of confinement as distances grow to the scale of 1 fm (i.e. hadron size): loss of the chiral symmetry property of the elementary QCD Lagrangian via non-perturbative generation of “massive” quark and gluon condensates, that replace the bare QCD vacuum.

While these theories led to important developments, they failed to reach their original goal. The present theory was arrived at in three steps.

Résumé :

An experimental study of the critical heat flux (CHF) and the associated limiting critical quality phenomenon has been conducted recently for horizontal and vertical tubes cooled with water and the refrigerant R-134a. The objective of this study is to compare the CHF and the associated limiting critical quality data obtained in horizontal and vertical tubes, in order to assess the effect of orientation on the CHF and the limiting critical quality. The investigated ranges of flow parameters in water (the R-134a equivalent values are given in brackets and have been transformed using the CHF flui

Résumé :

Abstract A free standing, slender body may experience rocking motion followed by overturning when it is subject to strong seismic motions. When the free body is submerged in water, it will also be subject to lateral forces acting along the side of the free body as a result of water sloshing. This highly non-linear situation is of particular interest to engineers in the nuclear industry in need to assess the stability of transfer casks containing spent fuel and submerged in a confined pit or pool. In this work, a three-dimensional finite element dynamic transient model of a free standing cask i

Résumé :

The Treaty on the Prohibition of Nuclear Weapons (TPNW) entered into force on 22 January 2021. As part of a project examining NATO obligations and how they interact with nuclear non-proliferation and disarmament law and policy, this paper focuses on what the entry into force of the TPNW should mean for members of the NATO Alliance. NATO has long maintained a strong unified position in opposition to the new treaty, meaning that under current circumstances it is unlikely that any NATO member will join the TPNW. But the reality for NATO, its members and partners is that the TPNW is now here to st

Résumé :

The UK government’s Integrated Review of security, defence, development and foreign policy, published in March 2021 alongside a supporting defence command paper, set a new course for UK national security and highlighted opportunities for an innovative approach to international engagement activity. The Integrated Review focused principally on the state threats posed by China’s increasing power and by competitors – including Russia – armed with nuclear, conventional and hybrid capabilities. It also stressed the continuing risks to global security and resilience due to conflict and instability in
