Bousnane, Z.; Merabtine, N.; Benslama, M.; Bousaad, F.
The goal of this survey is to deduce the grandeurs, or the set of grandeurs,
from which is derived simultaneously as a linear combination of densities of states,
current density matrix and the reduced entropy, according to the general fact that the
logarithm of the distribution is additive first integral. In this perspective, we introduce the
notations, which gives to the logarithm of the distribution as the
quaternionic picture of the operatorial transcriptions, this must follow the behaviour of a
canonical distribution through the interval of the transitions. It seems that the
nonreproducibility is caused essentially by the fact of absolute separability of dimensions
between the observed and observer. The reduced entropy will suggest the inner
displaying of observer, the invariance of unsymmetric order parameter products will be
an expression of reproducibility. We must have a displaying of such products over inner
dimensions, allowing to translate a limit of the displaying of stationary levels of
macroscopic bodies over inner distances. Iˆ is the parity operator and will act under
respect or violation of products as uncertainties, Jˆ is representing measurement process
decomposing layers, sublayers and orbitals according to the thresholds logics answering
how cold will be felt to transgress the conventional univoc filling rules, Kˆ represents
measurement process realising the centesimal entropy depth penetration. The
introduction of such notations will be justified by the fact that the ρ -distribution,
introduced as an unsymmetric product of order parameters, is defined per pavement –
pavement as defined by J.H. Poincaré.

Bousnane, Z.; Benslama, M.; Merabtine, N.
The “cold” causes superconductivity phenomenon, as a measurement process
generating a phase transitions of the second order, and also permitting the rise of
phenomenological parameters, but not allowing the stability of such behaviour, we will
have to write this stability to be supported by a new kind of value as an entropic potential
which learns the systems how to display over all possible microconfigurations, and the
systems by their faculties to increase their standard entropies, dictate the form of this
potential, this will be written as a recursive operatorial equations. The picture of such
potential is interference between thermodynamical length scales of entropies, it seems as
a world of different undetermination orders, if a given variational principle is put down,
it will transit over several definitions. The representation of the entropic potential as a
group transformation linking different temperature thermodynamical length scales as
described by L. Landau will suggest that among considerations brought on propagation
of order parameter carving the recursive stationary state. Concerning the stability
conditions, a context of matrices description will be proposed, as managing the fact that
superconductor, is superconductor per pavement, and the matrixes notations, is
determining the interaction between order parameters as “Heredity” concerning
dimensions, orientations and a mixed subinteraction, where equivalently dimensions and
orientations are mutually excluded each other. The beginning of emergence of this value
is rooted when combinatory formulation of matter, is taken in the order of measurement
process with eigen results, corresponding to normalised macroscopicity levels. The
asymptotic expression for the entropic potential, will be expressing a physical situation
defining that, deflections are collected by a variational principle brought on the Landau
length coherence. The introduction of covariant, contravariant and mixed current density
matrices will establish the limit, according which the reproducible recursive
configurations is only obtained by triplication of a combined fundamental states.

Primachenko, V.E.; Serba, O.A.; Chernobai, V.A.; Venger, E.F.
In this work, we continue to study the revealed phenomenon of current
creation in the electrochemical system with distilled water during its decomposition
without any applied external voltage. Investigated are catalytically active (to decompose
water) electrodes based on silicon with modified surface (due to lapping, texturing,
doping with palladium, creation of silicides) before and after thermooxidizing for 1 hour
in dry oxygen at 850 ºC. Also performed are investigations of time dependences for the
current between silicon electrodes and counter-electrodes made of Al, Pt, Yb when using
the circuit with the external voltage V₀ = ± 9.7 V. Analyzed are the results obtained and
prospects for a further study.

Kubytskyi, V.; Reshetnyak, V.
Presented is the study of the diffraction properties of transmission holographic
polymer dispersed liquid crystal (H-PDLC) grating. We constructed a two-dimensional
model of H-PDLC film with cylindrical LC droplets. Director distribution inside LC
droplets was calculated using the Monte-Carlo method. To calculate light propagation
through the film we have solved numerically the Maxwell equations using the finitedifference time-domain method (FDTD). The FDTD analysis of diffraction was
performed for s- and p-polarized incident light. Externally applied electric field influence
on the diffraction efficiency was studied.
