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.

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.

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.

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.
