The article presents a mathematical model of control over dynamic hierarchy system. The model was proposed for dealing with systems with assumed order in the technical problem of predicting destructions depending onto the amount of defects on different scale levels. The problem of the closest to a certain point of shelf life of hierarchy system is solved. The example of approach control during the given time is given. The problem concerns mathematic programming. Formulation of multi-parameter vector optimization criteria (improvement) with its own hierarchy and the formal exercise of multi-criteria optimization of the model parameters. The research can achieve clarity about the conditions under which the structure is preserved. Managing sustainable development system with a given level of the hierarchy for the technical systems can only be achieved in keeping

The author of this scientific article considers the computer-based document as a container of criminalistically significant information, which can be both orienting and evidentiary. The author also considers the opportunity of presenting computer-based documents to the court without application of paper information-carrying medium, i.e., there exists a possibility of procedural actions commitment directly with the mentioned computer-based document but not with its carrier. As an example, the author quoted an instance that executive officers listed in Article 181 of the Russian Federation Arbitration Procedure Code are entitled to demand and obtain the case from a relevant court of arbitration with the purpose of solving the problem concerning availability of grounds for lodging a protest in the exercise of supervisory powers
We have studied the question of the electromagnetic
structure of a relativistic electron in connection with
the Yang-Mills theory. From the Lorentz
electrodynamics equations of and Dirac electron
theory derived an equation describing nonlinear
waves of the scalar potential. It is shown that this
equation is similar to the equation describing the
dynamics of the condensate in the Yang-Mills theory.
There is also the connection to the Schrödinger
equation: the scalar potential is a complex function,
similar to the wave function in the Schrödinger
theory. The model discussed electron is a solitary
wave that occurs in the electromagnetic field. This
wave has the properties of charged particles, able to
interact with the external electric and magnetic field.
An analytical solution describing solitary
electromagnetic waves traveling at a speed less than
the speed of light has been obtained. The existence of
solitary electromagnetic waves consistent with the
Hertz's hypothesis that suggested that cathode rays
are a form of wave motion in an electromagnetic
field. The proposed model of the electromagnetic
structure of the electron thus solves the problem of
duality wave-particle, which historically arose in the
interpretation of experiments with cathode rays.
Numerical modeling of electromagnetic electron
structure shows that the initial state such as a
spherical shell is unstable and disintegrates into a pair
of nonlinear waves that leave the system with the
speed of light. In the decay of the initial state
concentrated in the neighborhood of the origin, waves
of complex part of potential disappear with time, but
a real part of the potential it tends to equilibrium
The article covers the basics of thermodynamics and the possibility of the application of its provisions to the basic biological entity - the cell under the influence of external electromagnetic fields. Thus, we consider a system whose properties do not change in time, if it does not occur on the external influences. If the system is subjected to such (mechanical, thermal, electrical, magnetic and other effects), then all its properties, or some of them are changing. If at least one property of the system changes, we will talk about changing the status of the system due to the fact that there was some process. From the point of view of external electromagnetic fields on the thermodynamic system - a cell of a living organism or plant is very important essence of the concept of work. Unlike conventional concepts of the work of expansion (pdV), which is not considered to be useful, we have introduced the concept of "useful" work dA /, which means the operation of the electric current, magnetic field or other physical fields in the design of various electrical devices and appliances used in livestock and crop. The impact of electromagnetic fields on biological objects also leads to a slight increase in temperature of the biological system and, as a consequence, it increases the rate of chemical and biochemical reactions and phase transitions, which is reflected in the increased activity of the biochemical processes in these objects. This, to some extent can explain numerous experimental results of scholars and practitioners concerned with stimulating crops, for example, during preplant treatments
The stability of strongly basic anion-exchange membranes MA-41-2P (JSC "Schekino-Nitrogen", Russia) and AMX (Tokuyama Soda, Japan) under intensive current regimes was investigated in the
current study. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail. The length of the electroconvective instability at the membrane / solution interface at currents
exceeding the limiting current was measured by laser interferometry
Micro and nanofluidics are the new multidisciplinary
sciences. One of the tasks of which is creation and
management of flow of fluid in the thin channels size
of a few nano- or micrometer which exposed the
external electric field, where the walls are the ion
exchange membrane. Electroosmosis
(electroconvection) plays an important role in these
tasks. A large number of articless were devoted to
electroosmosis. One of the first, Dukhin S.S.,
Mishchuk N.A. and Rubinstein I. gave a theoretical
explanation of the overlimiting current by
electroosmosis. They used two-dimensional Stokes
equation to calculate the flow of the electrolyte, and
one-dimensional equations of Nernst-Planck and
Poisson to calculate the electric power. These
researches have multiple limitations because of the
computational complexity the mathematical
simulation. Thus, there is an actual problem of the
asymptotic solution of boundary value problems for
the two-dimensional systems of equations of NernstPlanck
and Poisson without these restrictions. These
researches we derived in simplified models of
electroosmosis in galvanic dynamical mode using the
decomposition method. We have created a hierarchical
system of two-dimensional mathematical models of
ion transport of salt and electroosmosis in micro- and
nanochannels formed by selective ion-exchange
membranes
In the article, we have described an electro solar water heating system for agricultural consumers. The results of computer modeling in the “Modeling in technical devices” software package have been given
The absence of theoretical bases for interaction of the
magnetic field and cellular mechanism, the lack of an
effective way to determining the results of this action
has led to the creation of a large number of machines
and devices of electromagnetic influence on
biological objects of vegetable and animal origin.
Many of them are contain special generators and
inductors developed for a specific type of object. By
means of these constructions, used in electro
technological processes at agricultural companies of
the Kuban region, we increase productivity of
different crops, increase productivity of animals and
poultry, change the physical and chemical properties
of liquids and solutions, conducted in boiler water
preparation. A distinctive feature of the
electromagnetic field processing of objects of
biological origin is sufficiently high efficiency of
outcomes at insignificant energy costs. All this
foreshadows further improve the long-term
development and research in this area. By analyzing
the existing devices, it can be concluded, that all of
presently available designs for electromagnetic
treatment are classified by a common attribute - a
method for creating a magnetic field. The lack of
reliable, logically complete theory of influence of
electromagnetic influence on biological systems
agricultural purpose and the availability of practical
recommendations when to use inductors working on
constant, and when the AC has led to the fact that to
obtain the necessary effect, share the same devices
have become connected to various sources of supply
