The electron is interpreted as a small electric current carrying the elementary charge and the elementary mass. The equivalent circuit is a quarter-wave short circuited transmission line, the line having characteristic impedance 25812.807449 Ohm, the von Klitzing constant.
A similar line, closed on itself after a twist (as in a Moebius strip), not only justifies the charge and mass, but also the angular momentum of the electron.

Through a convenient mathematical approach for the Navier-Stokes equation, we obtain the quadratic dependence $v^{2}$ of the drag force $F_{D}$ on a falling sphere, and the drag coefficient, $C_{D}$, as a function of the Reynolds number. Viscosity effects related to the turbulent boundary layer under transition, from laminar to turbulent, lead to the tensorial integration related to the flux of linear momentum through a conveniently choosen control surface in the falling reference frame. This approach turns out to provide an efficient route for the drag force calculation, since the drag force turns out to be a field of a non-inertial reference frame, allowing an arbitrary and convenient control surface, finally leading to the quadratic term for the drag force.

Particles on a plate form Chladni patterns when the plate is acoustically excited. To better understand these patterns and their possible real-world applications, I present a new analytical and numerical study of the transition between standard and inverse Chladni patterns on an adhesive surface at any magnitude of acceleration. By spatial autocorrelation analysis, I examine the effects of surface adhesion and friction on the rate of pattern formation. Next, I explore displacement models of particles translating on a frictional surface with both adhesive and internal particle-plate frictions. In addition, I find that both adhesion and damping forces serve as exquisite particle sorting mechanisms. Finally, I discuss the possible real-world applications of these sorting mechanisms, such as separating nanoparticles, organelles, or cells.

In order to explain why (i.e. cause) and how (i.e. way) superconductivity is generated and related properties and its effects take place, presently a new theory has been propounded determining such a cause over which unfortunately, despite having its knowledge, nobody ever tried to think, while it acts as the true cause. Consequently, the present theory gives a very clear and complete explanation (picture) why and how superconductivity is generated and related properties and its effects take place. So far unexplained some properties have also been explained, e.g.: 1. Why and how transition temperature ( ) varies from substance to substance; 2. Why and how very good conductors of current, e.g. gold, silver, copper do not superconduct even down to very low temperatures; 3. Why and how ferromagnetic substances do not superconduct; etc. Most important- it has also been tried to explain how currently known some non-superconducting (e.g. ferromagnetic) substances can be made superconducting. In order to verify/justify the truth of the determined cause, plausible arguments and evidences have been given from the well-established knowledge. The existing theories fail to give a clear and complete explanation as to how superconductivity is generated and related properties and effects take place, which is their great drawback. Because, whenever any phenomenon takes place, there occurs always a way (procedure), how that phenomenon and related properties take place, and hence if any theory is developed in order to explain that phenomenon, the theory must give a clear and complete explanation how that phenomenon and related properties take place. The existing theories, in addition, give rise to several such questions of which no any explanation can be given. The BCS theory for which it is claimed that it provides better explanation and accounts very well for all the properties exhibited by the superconductor. But if we examine this theory closely, we find that it is based on such concepts which: 1. Are practically not possible; 2. Contradict two well-observed facts; 3. Give rise to numerous such questions of which no explanation can be given. These drawbacks raise serious question mark over the truth of the BCS theory. Finally, some possible new effects have been predicted and it has been tried to explain why and how they shall take place.

When an electric current flows through any conducting rod: 1- Why and how is a magnetic field
generated around the rod? 2- Why and how does this field occur in a plane perpendicular to the
direction of flow of current and possesses direction? 3- How and which type of magnetism
(electromagnetism) is generated? How do electrons move together in electron beams despite
having repulsive Coulomb force between them? Why and how does the Lorentz force come into
play? No explanation is found how these phenomena take place. Electromagnetic theory has
wide success to its credit but it and other theories fail to do so. These theories fail
because there are some causes behind the occurrence of these phenomena but no account of
those causes have been taken into consideration. The causes are, e.g.: 1- The electron
possesses magnetism by virtue of nature similarly as it possesses charge by virtue of nature,
and magnetism occurs in the form of a ring around the charge of electron, 2- The magnetism
of the electron spins similarly as it's charge spins but in opposite directions, 3- The
interaction between magnetic fields of interacting particles (e.g. between magnetic fields
of electrons in electron beams) or interacting systems give rise to a force between them.
Presently, taking into account the above causes, a new theory has been propounded which
gives a very clear and complete explanation of all the above phenomena. The force caused
due to interaction between magnetic fields of electrons has some very important and
striking properties: this force is strong, short range and charge independent. Since the
nature of this force is exactly similar to what we speculate for nuclear force between
nucleons, and nucleons possess a magnetic field too, the nuclear force should be due to
interaction between magnetic fields of nucleons in nuclei. Most importantly, this force
has a repulsive component too, which is very essential to cause, e.g. alpha and beta
decays etc. because the Coulomb repulsive force is too weak and hence cannot cause these
decays. How this force varies, that has been determined. To confirm the truth of the
determined force, so far unexplained an important mysterious nuclear phenomenon has been
explained. Finally: i- effects of the present theory on some important current concepts
and their consequences have been discussed; and ii- some possible new effects have been
predicted and explained why and how they shall take place.

We propose a universal approach in the framework of the lattice Boltzmann
method (LBM) to modeling constant velocity constraints and constant temperature
constraints on curved walls, which doesn't depend on dimensionality, LBM scheme,
boundary geometry; which is numerically stable, accurate and local and has a good
physical background. This technique, called a maximum entropy method, utilizes the idea
of recovering unknown populations on boundary nodes through minimizing node state
deviation from equilibrium while assuring velocity or temperature restrictions. Also,
theoretical justifications of a popular Zou-He boundaries technique and isothermal
boundaries algorithm are provided on the basis of the method derived. Finally, while
conducting numerical benchmarks, typical straight boundaries algorithm (Zou-He) was
compared to a typical curved boundaries algorithm (Guo-Zheng).

The tridimensional morphology and etching kinetics of the etch pit on the C-{0001}
plane of sapphire crystal (a-Al2O3) in KOH molten were studied experimentally. It was shown that
the etch pit takes on tridimensional morphologies with triangular symmetry same as the symmetric
property of the sapphire crystal. Pits like centric and eccentric triangular pyramid as well as
hexagonal pyramid could be observed, but the latter is much less in density. Analyses show the side
walls of the etch pits belong to the {1 0 } family, and the triangular pit contains edges full
composed by Al3+ ions on the etching surface so it is more stable than the hexagonal pit since
whose edges on the etch surface contains Al2+ ions. The etch pits developed in manner of kinematic
wave by the step moving with constant speed controlled by the chemical reaction with activation
energy of 96.6KJ/mol between Al2O3 and KOH.

A model relating the diameter variation with the process parameters during a practical
crystal growth by pulling has been proposed. The crystal shape evolution under various growth
process was analysed. The results prove, in theory, that the most effective and convenient measure
to control the crystal diameter is adjusting the pulling rate, and the optimal process for growing a
equal diameter crystal is simultaneously decreasing the pulling rate and the heater temperature
with dropped decreasing rate. Moreover, the model could be used for designing the process for
growing a crystal with a desired shape.

and decreasing the convex extent of solid liquid interface could enhance the increase rate of crystal diameter

This PhD thesis examines the thermodynamical properties of spin-1/2 Heisenberg chains which are
coupled to Einstein phonons. One result of this study is that these spin-phonon systems undergo a
phase transition similar to a spin-Peierls transition (cf. Physical Review B 60 (1999) 12125-12133
and Physical Review B 65 (2002) 144438). Another result is that in the undimerized phase the critical
exponent nu depends on both the phonon frequency and the spin-phonon coupling constant. This means
that these spin-phonon systems change the universality class continuously with the spin-phonon
coupling (cf. arXiv: cond-mat/9912150v1).

The most astonishing properties of condensed matter are the formation of collective quantum
states of superconductivity, magnetic order, electric order and crystalline order. In this paper,
new universal formulas for transition temperatures are derived, that depend simply on atomatom
distances, atomic masses and electron masses. The universality of these formulas is
tested by comparing the calculated values and experimental data for critical temperatures of
different systems and phases.

The article shows that in case if the photon is viewed as a particle moving in empty space
the zero value of chemical potential of equilibrium electromagnetic radiation cannot be explained
basing only on first principles of statistical physics. On the contrary, to explain the chemical
potential of equilibrium electromagnetic radiation being equal to zero is rather simple if the photon
is considered as a quasi-particle that is the way to describe collective motion of a system consisting of
particles whose number is a fixed value. Collective motions of the particles of mentioned system are
interpreted in the article as oscillations of an electromagnetic field that corresponds to observation
data of modern astronomy, according to which the space, that fills the gaps, both between massive
objects and between massive particles forming them, should be attributed to characteristics of a
continuous medium.

The PdO-coated layer of Pd-nano-particle may arrange fractal nano-dips on its surface when D(H)-gas
is charged and de-oxidation molecules (D2O or H2O) are released.
Fractal nano-dips may make local deep adsorption potentials, through which rapid penetration of D-atoms
(ions) into deeper Pd-local lattice (Bloch potential) O-sites of nano-particle may be induced, to realize
full or over-full D(H) loaded state (x>1.0) of PdDx in a short time of the Phase-I process. Formation of
D-clusters, such as 4D/TSC on surface may be enhanced at nano-dips. A phenomenological model of quasi-free
D-motion under constraint of the Bloch potential within a global mesoscopic potential well is proposed
for the Phase-II phenomena, where nuclear heating by 4D fusion reactions may rather steadily take place.
Generation of collective mesoscopic potential well (CMPW) will make a Pd nano-particle with PdO working
as "mesoscopic catalyst" which realizes very large D(H)-loading ratios and anomalously large chemical heat
releases both for H-gas and D-gas loading.

Discussions with brief summary of the Kobe group's experiments are given. Phenomenological
modeling on mechanisms are made for explaining observed anomalies in D(H)-overloading and high
heat-power release rates from nano-palladium-particles and binary metal PdNi nano-particles
dispersed in/on ZrO2 ceramics supporter flakes under D(H)-gas loading at room temperature. Roles
of PdO layer and Pd-ad-atoms (incomplete outer shell) of nano-Ni-core are modeled as mesoscopic
catalysts which have sub-nano-holes (SNH) on nano-particle-surfaces. SNH may realize strong
sticking force for D(H)-gas to dissociate and diffuse rapidly into inner local lattice sites.
During the beginning process, 4D/TSC cluster fusions with 1watt/g-Pd(or PdNi) may happen on
surface. By the very over-loading (x>>1) states in the later region of Phase-I and in the
Phase-II after saturation, TSC formation inside nano-particles may be strongly enhanced by the
non-linearly coupled QM oscillation (high free energy states of deuterons in local Bloch
potentials) under the deep mesoscopic global collective potential well.

The interface shape function for the pure material directional solidification system with
temperature disturbances on the heater and cooler is derived. It is approximately a fraction function
including cosine terms in the denominator and the numerator. Calculation of the function shows the interface
shape can respond to the temperature disturbance. When both the solidification rate V and the interface
cooler distance α determined by the boundary temperatures are lower than critical value deteimined by a
formula, the interface shape changes from sinusoidal wave to figures pattern with the increase of the rate or
the distance. Once the rate or the distance reaches the critical value, the interface branches at the bottom of
the grooves between figures and then the branches expand along the sidewall of the figures with further
increase of the rate or the distance. According to that, we conclude that the sinusoidal interface shape
assumption always used by the interface instability analyses is not always valid and the interface shape in
Hele-Shaw solidification experiments in fact maybe is not planar but a cellular interface with quite small
amplitude, and the role of temperature disturbance should be considered in experiments studying
solidification interface stability.

We consider superconductivity in the light of the quantum gravity theoretical framework
introduced in [1]. In this framework, the degree of quantum delocalization depends on the
geometry of the energy distribution along space. This results in a dependence of the critical
temperature characterizing the transition to the superconducting phase on the complexity of
the structure of a superconductor. We consider concrete examples, ranging from low to high
temperature superconductors, and discuss how the critical temperature can be predicted
once the quantum gravity effects are taken into account.

It is demonstrated clearly that for the same
classic generalized system the Tsallis power-laws with both
the q > 1 and the q < 1 can be induced by the constraint
of the constant harmonic mean for the so-called reciprocal
energies r E and at the same time the Boltzmann
distribution or the negative exponential probability
distribution can be generated with the constraint of the
constant arithmetic mean for the generalized energies E .
The author thus argues that there might be no definite
"extensive system" or "classic system" and there are only
"classic physical parameters" and "classic constraints".
For any physical system or generalized system, it is the
non-natural constraints which determine both the forms of
the entropies and the non-uniform equilibrium
distributions.

Emergent physics refers to the formation and evolution of collective patterns in systems
that are nonlinear and out-of-equilibrium. This type of large-scale behavior often develops
as a result of simple interactions at the component level and involves a dynamic
interplay between order and randomness. On account of its universality, there are credible
hints that emergence may play a leading role in the Tera-ElectronVolt (TeV) sector of
particle physics. Following this path, we examine the possibility of hypothetical highenergy
states that have fractional number of quanta per state and consist of arbitrary
mixtures of particles and antiparticles. These states are similar to "un-particles", massless
fields of non-integral scaling dimensions that were recently conjectured to emerge
in the TeV sector of particle physics. They are also linked to "unmatter", exotic clusters
of matter and antimatter introduced few years ago in the context of Neutrosophy.
The connection between 'unmatter' and 'unparticle' is explained in details in this paper.
Unparticles have very odd properties which result from the fact that they represent fractional
field quanta. Unparticles are manifested as mixed states that contain arbitrary mixtures of
particles and antiparticles (therefore they simultaneously evolve "forward" and "backward" in time).
From this, the connection with unmatter. Using the fractal operators of differentiation and
integration we get the connection between unparticle and unmatter. 'Unmatter' was coined by
F. Smarandache in 2004 who published three papers on the subject.

Besides matter and antimatter there must exist unmatter (as a new form of matter) in
accordance with the neutrosophy theory that between an entity <A> and its opposite
<AntiA> there exist intermediate entities <NeutA>. Unmatter is neither matter nor
antimatter, but something in between. An atom of unmatter is formed either by (1):
electrons, protons, and antineutrons, or by (2): antielectrons, antiprotons, and neutrons.
At CERN it will be possible to test the production of unmatter. The existence of
unmatter in the universe has a similar chance to that of the antimatter, and its production
also difficult for present technologies.

One of the most reported problem related to the CMNS (condensed matter nuclear science, or
LENR), is the low probability of Coulomb barrier tunneling. It is supposed by standard physics
that tunneling is only possible at high enough energy (by solving Gamow function).
However, a recent study by A. Takahashi (2008, 2009) and experiment by Arata etc. (2008)
seem to suggest that it is not impossible to achieve a working experiment to create the CMNS
process.
In accordance with Takahashi's EQPET/TSC model [1][2][3], the proposed study will find out
some analytical and numerical solutions to the problem of barrier tunneling for cluster
deuterium, in particular using Langevin method to solve the time-independent Schrödinger
equation. It is hoped that the result can answer some of these mysteries.

The catalyst-free sonogel route was implemented to fabricate highly pure,
optically active, hybrid azo-dye/SiO2-based spin-coated thin films deposited onto ITO-covered glass
substrates. The implemented azo-dyes exhibit a push-pull structure; thus chromophore electrical
poling was performed in order to explore their quadratic nonlinear optical (NLO) performance and
the role of the SiO2 matrix for allowing molecular alignment within the sonogel host network.
Morphological and optical characterizations were performed to the film samples according to
atomic force microscopy (AFM), ultraviolet-visible (UV-Vis) spectroscopy and the Maker finger
technique. Regardless of absence of a high glass transition temperature (Tg) in the studied
monomeric liquid crystalline azo-dyes, some hybrid films displayed stable NLO activity such as
second harmonic generation (SHG). Results show that the chromophores were homogeneously
embedded within the SiO2 sonogel network, where the guest-host molecular and mechanical
interactions permitted a stable monomeric electrical alignment in this kind of environment.

The author shows that the Maxwell's equations in vacuum have solutions
which have helical structure in space while being circularly polarized at the
same time. This goes against the universally accepted solutions which treat the
electromagnetic wave as sinusoidal wave propagating along a linear path. He
shows that the helical wave structure assumes that the fundamental state of the
electromagnetic wave is the circularly polarized state and not the linearly
polarized state. Since the photon is theorized to exist in a circularly polarized
state, the proposed new solution is consistent with that picture. The author
proposes a simple experiment using a maser to confirm the veracity of the
proposed helical structure.

We describe an empirical study of the formation of knots in open and closed self-avoiding walks
(SAWs), based on a simple model involving randomly agitated cords. The results suggest that
the probability of a closed SAW remaining knot-free follows a similar scaling law to that for
open-ended SAWs. In particular, the process of closing a given SAW prior to random agitation
substantially increases the probability that it will be knot-free following agitation. The results
point to a remedy for the well-known problem of tangling of cord, rope, headphone cables etc.
The simple act of connecting the two free ends to each other, thus creating a loop, greatly
reduces the risk of such tangling. Other implications, in particular for DNA storage in cells, are
briefly discussed.

a technique initially applied to density wave current calculations to questions of instanton
formation in multi dimensional condensed matter systems. Initially we review prior calculations
done through a numerical simulation that the massive Schwinger model used to formulate solutions
to CDW transport in itself is insufficient for transport of soliton-antisoliton (S S') pairs
through a pinning gap model of CDW transport. Using the Peierls condensation energy permits
formation of CDW S S' pairs in wave functionals. This leads us to conclude that if there is a
small spacing between soliton-antisoliton (S S') charge centers, and an approximate fit between
a tilted washboard potential and the system we are modeling, that instantons are pertinent to
current/transport problems. This requires a very large 'self energy' final value of interaction
energy as calculated between positive and negative charged components of soliton-antisoliton
(S S') pairs with Gaussian wave functionals as modeled for multi dimensional systems along the
lines of Lu's generalization given below. The links to a saddle point treatment of this
instanton formation are make explicit by a comment as to a cosmology variant of instanton
formation in multi dimensions we think is, with slight modifications appropriate for
condensed matter systems

Comments: 15 pages. Mathematical / condensed matter joint piece designed to explain
the congruence of the Bogomol’nyi inequality with the fate of the false vacuum hypothesis as given by Sidney Coleman.
Foundational issue involved which was key to up dates as to my PhD dissertation, and subsequent work in terms of the
tunneling Hamiltonian, and I-E curves in laboratory data taking. Note , the Bogomol’nyi inequality is a key work horse
as to PARTICLE/ Astro physics, as is the false vacuum hypothesis
We examine quantum decay of the false vacuum in the driven sine-Gordon
system and show how both together permit construction of a Gaussian wave
functional. This is due to changing a least action integral to be similar with
respect to the WKB approximation. In addition we find that the soliton-antisoliton
(S-S') separation distance obtained from the Bogomol'nyi inequality permits after
rescaling a dominant &phi2 contribution to the least action integrand. This is from an
initial scalar potential characterized by a tilted double well potential construction.

Comments: 18 pages, Constitutes one fifth of the author's PhD dissertation
at the U. of Houston, in late 2001. Remainder of dissertation used Sidney Coleman's
"fate of the false vacuum" article, plus the Schwinger equation, with chain
couplings to fix short comings evident in the simulations presented in this
document. 6 figures.
We have evidence that the classical random pinning model, if simulated numerically using
a phase evolution scheme pioneered by Littlewood, gives dispersion relationships that are
inconsistent with experimental values near threshold. These results argue for a revision
of contemporary classical models of charge density wave transport phenomena. Classically,
phase evolution equations are in essence driven harmonic oscillator models, with perturbing
terms plus damping. These break down when we are adding more 'energy' into a measured sample
via an applied electric field than is dissipated via a damping coefficient behavior in a
phase evolution equation. We see the consequences of the breakdown of these phase evolution
models in Charge Density Wave conductivity and dielectric functional graphs.

By exerting a magnetic field normal to a current-carrying strip we
cause a deviation in the path of moving electrons as if our conducting path
is a wire along an edge of the strip which at a point is deflected normal
to the edge and reaches the other edge and afterwards is continued along
this other edge in the same direction as before. It is clear that connecting
the two end points of the transverse part of such a wire by a minor wire
we expect a part of the main current to pass through this minor wire. The
direction of such a current flowing in the minor wire is such that as if the
current-carrying charges in the main current-carrying strip are positive
charges. This is the basis of this article. A quite practical experiment is
proposed for testing the presented theory.

In a gradient of magnetic field, magnetic dipoles of the air are attracted
toward the region of intense field such that the air pressure is more in the
regions of more intense field. The formed pressure gradient exerts a net
force on a body placed in the air in this gradient of magnetic field toward
the region of low pressure or the region having weaker field. This is like
what takes place in sink-float separation.

It is shown that there exists a uniqueness theorem, stating that the
charges given to a constant configuration of conductors take a unique distribution,
which contrary to what is believed does not have any relation to
the uniqueness theorem of electrostatic potential. Using this theorem we
obtain coefficients of potential analytically. We show that a simple carelessness
has caused the famous formula for the electrostatic potential to be
written as U = 1/2 ∫D.Edv while its correct form is U = 1/2 ∫D.Eρdv
in which Eρ is the electrostatic field arising only from the external charges
not also from the polarization charges.
Considering the above-mentioned material it is shown that, contrary
to the current belief, capacitance of a capacitor does not at all depend
on the dielectric used in it and depends only on the configuration of its
conductors. We proceed to correct some current mistakes resulted from
the above-mentioned mistakes, eg electrostatic potential energy of and the
inward force exerted on a dielectric block entering into a parallel-plate
capacitor are obtained and compared with the wrong current ones.
It is shown that existence of dielectric in the capacitor of a circuit
causes attraction of more charges onto the capacitor because of the polarization
of the dielectric. Then, in electric circuits we should consider the
capacitor's dielectric as a source of potential not think wrongly that existence
of dielectric changes the capacitor's capacitance. Difference between
these two understandings are verified completely during some examples,
and some experiments are proposed for testing the theory. For example
it is shown that contrary to what the current theory predicts, resonance
frequency of a circuit of RLC will increase by inserting dielectric into the
capacitor (without any change of the geometry of its conductors). It is
also shown that what is calculated as K (dielectric constant) is in fact
2 - (1/K).

This paper gives the follow-up study on the basics for our previous papers, Study on
4D/Tetrahedral Symmetric Condensate Condensation Motion by Non-Linear Langevin Equation,
Symposium 998-Low Energy Nuclear Reactions Source Book, ACS, published on August 2008
from Oxford University Press.
Pertaining to the quantum mechanics, the basics of new approach using the stochastic
differential equation (Langevin equation) is written for quantifying dynamic motion of
known molecules as D2+, D2 and D3+
as well as D-atom state. The role of the Platonic
symmetry in these known molecules are discussed for deducing simple one-dimensional
(Rdd dependent; here Rdd is distance between nearest d-d pair) Langevin equation and
making quantum-mechanical ensemble averaging to obtain equation for expectation value.
The methodology is applied for more complicated D-clusters as 4D/TSC and 6D/OSC which
would keep the Platonic symmetry, by introducing the force fluctuation deviating from
the ideal Platonic symmetry. Time-dependent TSC and OSC trapping potentials which take
balance to getting back to the Platonic symmetry from the distorted states were defined
and used for numerical solution of Langevin equation. Finally, time-dependent fusion
rate formula for simultaneous 4D interaction was obtained based on the Fermi's golden
rule and one-pion exchange potential of strong interaction. The 4D fusion is regarded to
cause radiation-less excess heat and 4He ash in metal-deuterium systems under dynamic conditions

Tetrahedral symmetric condensate (TSC) with 4 deuterons and 4 electrons has been proposed as
a seed of clean 4D fusion with 4He product in condensed matter. To solve molecular dynamics
motion of 4D/TSC condensation, a nonlinear Langevin equation was formulated with a Coulombic
main condensation force term under Platonic symmetry, 6 balancing forces by quantum mechanical
electron clouds of dde*(2,2) EQPET molecules on 6 faces of TSC cube and a random quantum
mechanical fluctuation term f(t) for d-d distance. Gaussian wave functions for d-d pairs and
their ground state energies were first obtained by variational method, for D2 and EQPET molecules.
Then same sigma-value was used for time-dependent Gaussian wave functions of d-d pairs of TSC
system to calculate the ensemble-averaged <f(t)> for changes of Coulomb energy and force of
distorted TSC system deviated from the ideal double Platonic symmetry. Molecular dynamics
calculation with TSC Langevin equation by the Verlet time-step method was then done. We
obtained mean relative final-stage d-d kinetic energy 13.68 keV with -130.4 keV deep trapping
TSC potential at Rdd-minimum = 25 fm and time-to-TSC-minimum =1.4007 fs. Mean kinetic energy
of electron of a "d-e-d-e" EQPET molecule of TSC system was estimated as 57.6 keV at Rdd =25
fm. These time-dependent trapping potential for d-d pair of TSC can be approximated by HMEQPET
potentials with the empirical relation of m=4.36x104/Rdd, (Rdd in fm unit), continuously as a
change of condensation time or Rdd(t). Barrier factors for fusion reactions as a function of
Rdd(t) and 4D fusion rate per TSC generation were calculated using these HMEQPET potentials
and Fermi's golden rule. We found that 4D/TSC got to the TSC-minimum state with 10 fm-20 fm
radius in 1.4007 fs and 4D fusion rate was 100 % per 4D/TSC generation-condensation. Thus we
concluded that 4He production rate by 4D/TSC was equal to two times of 4D/TSC generation rate
in condensed matter (e.g., PdDx).

This brief paper is part of my research on the origins of turbulence. Since the derivations of the Navier-Stokes equation are frequently cumbersome, I would like to provide this pedagogical derivation (I hope), discussing the properties of the continuum fluids under a heuristical approach, viz., we provide a heuristical derivation of the so-called Navier-Stokes equation. We turn out to be concerned with the physical insight regarding the system under consideration, a system of continuum. Derivations of the Navier-Stokes equation are, frequently, pedagogically cumbersome, loosing the main heuristics one should grasp under the transition to the continuum. This transition turns out to naturally encapsulate neglected degrees of freedom due to the intrinsically thermodynamic domain. This pedagogical derivation discusses the properties of the continuum fluids and the relation to the taken limit encapsulating the continuum hypothesis, which turns out to raise the question of lack of validity over extremely distorted subdomains, once a grown rarefied subdomain may not provide sufficient large statistics to a smooth description via its center of mass, which is the main hypothesis of the infinitesimal limit process for the local description under the continuum hypothesis. Such transient, albeit not presented here, once it would change the characteristic of this paper to the research one connected to the important question of unicity of the (3+1)-dimensional Navier-Stokes differential equation, is to be pointed out, once it provides ansatz for research on the unicity of description of fluids by the Navier-Stokes equation.

Through a convenient mathematical approach for the Navier-Stokes equation, we obtain the quadratic dependence $v^{2}$ of the drag force $F_{D}$ on a falling sphere, and the drag coefficient, $C_{D}$, as a function of the Reynolds number. Viscosity effects related to the turbulent boundary layer under transition, from laminar to turbulent, lead to the tensorial integration related to the flux of linear momentum through a conveniently choosen control surface in the falling reference frame. This approach turns out to provide an efficient route for the drag force calculation, since the drag force turns out to be a field of a non-inertial reference frame, allowing an arbitrary and convenient control surface, finally leading to the quadratic term for the drag force.

The paper presents a study of the mechanisms of vacuum
polarisation. The electric field intensity and magnetic induction are
presented as components of a self-consistent force field of the
polarised vacuum. The method used makes it possible to deduce the
Maxwell equations and give a physical interpretation of the electric
displacement, magnetic field intensity, and the displacement current.
The new approach allows us to obtain the material relations for the
electromagnetic field in vacuum and to give a theoretical explanation
of the transformation of the field in the inertial frames.

The interesting and fascinating physical phenomenon of
superconductivity appears, until now, only at very low temperatures
and therefore its technical application is limited to relatively few
areas. If it is possible to create materials which are superconducting
at room temperature, then this could initiate a revolution in
technology. More than 10 years fundamental research, experience,
knowledge and ideas in the field of special materials (oxides) lead to
the conviction that superconductivity at room temperature is possible,
and together with Global Scaling - a new knowledge and holistic
approach in science - to an extended approach on the search for
room temperature superconductors.

The author shows that the Maxwell's equations in vacuum have solutions
which have helical structure in space while being circularly polarized at the
same time. This goes against the universally accepted solutions which treat the
electromagnetic wave as sinusoidal wave propagating along a linear path. He
shows that the helical wave structure assumes that the fundamental state of the
electromagnetic wave is the circularly polarized state and not the linearly
polarized state. Since the photon is theorized to exist in a circularly polarized
state, the proposed new solution is consistent with that picture. The author
proposes a simple experiment using a maser to confirm the veracity of the
proposed helical structure.
