Investigation

Abstract. By the
methods of Auger-electron spectrometry (AES), scanning electron microscopy (SEM), fast electron diffraction (FED) and wavelength dispersive spectrometry (WDS), there were carried out complex investigations on the structure and elemental distribution in the Beilby layer formed during mechanical polishing of ground
surface of Fe-44%Cr-4%Al-0.3%La alloy. It was established that the Beilby layer
formed during mechanical polishing of ground surface of the investigated alloy
consists of two sub-zones with uniform thicknesses combined with each other
organically. The first (outer) zone with thickness of ~250Å is a truly
amorphous layer saturated with oxygen and carbon atoms; and the second,
underlying (inner) zone of ~350Å thickness, which also has high
concentration of oxygen and carbon, is of a nanocrystallite (~20Å)
structure (in roentgen-amorphous state). The ratio between the thicknesses of
the given zones, which compose the Beilby layer, to a certain extent depends on
the polishing duration and the condition of the initial surface antecedent to
mechanical polishing. On the basis of observable peculiarities of the character of changes in the thickness of
revealed zones depending on the polishing duration and the initial surface
condition before mechanical polishing, there have been of developed notions of
the hierarchical sequence of stages of formation of the Beilby layer (and
layers under it) as a product of the combination of processes of visco-plastic
mass-transfer and growth of crystal structure defects, which are accompanied by
plastic deformations. The stabile existence at room temperature of the superficial layers with
truly amorphous and “roentgen-amorphous” states, which are so
nonequilibrium against the underlying
crystalline structure, is explained by the dissolution of those layers with
carbon and oxygen atoms and their interaction with the basic atoms which
compose the investigated alloy.

Quenching
of triplet states with phenols
Kokrashvili T. A., Shengelia M.A. and Kokrashvili
A. T.
There are given the values of the Kinetic isotopic
effect at quenching of triplet states of quinines with 3A phenols
which justify the mechanism of quenching proposed in this and previous works.
According to this mechanism, the kinetics of quenching and the quantum yield of
radicals are determined by three elementary stages: the process of formation of
the complex with a hydrogen bond, the transfer of hydrogen atom and the
photolytic equilibrium in the complex formed. The isotopic effect for the rate
constant of quenching of triplet states of quinines with phenols increases, as
increases the acidity of phenol, and then decreases again.

The peculiarities of annealing of defects of the Ec-0.17 eV level in Irradiated n-Si
Pagava T.A.,
Kharashvili O.G., Maisuradze N.I., Khasia N.I. and Kanchaveli D.E.
In the n-Si crystals irradiated with protons having
the energy of 25MeV, the radiation-induced defects of the Ec-0.17 eV
level were annealed in two stages: Tan=2000C and
3000C. It is demonstrated that, unlike the divacancy (V2),
Tan of the defects annealed at 2000C does not depend on
the concentration of disordered regions (DR). This points to the fact that
these defects are of the internode CiCs - type (internode
carbon-carbon in a node). At Tan=3000C, the A-centers are
annealed. The negative annealing of A-centers and V2 is connected
with dissociation of DR.

SUMMARY
On the generality of the notion of duality of evolution
and revolution
Khvedelidze
M.A.
The
author supposes that the duality of evolution and revolution could be realized
with consideration of existing certain similarity in the processes of
self-organization of various systems from physical-chemical to biological and
social ones and, at the same time, of their certain difference from their
initial level. But the history of all revolitions has always been in the transient
period, in the state of inevitable chaos. The possibility of transition to a new
stable state requires a great amount of energy. In this case, the general rule
of duality of structural organization of matter acts like in the case of dual
polar-pair states of the matter. The author considers that the existence of
inverse transformation from the state of order to the state of chaos today can
be justified by the example of the social system. Later, after studying
thoroughly the physical vacuum, it would be also possible to demonstrate the
inverse transformation of diffused energy and information into the concentrated
state according to the absolute principle of conservation of energoinformation.
It is stated that, without formation of at least a single type of dual regular
polar-pair state of matter, the Earth itself could not have emerged.

The block diagram of the system of prediction of

information about a phenomenon, a process or an object to be predicted enters
the prediction system via its input, and the data on the expected parameters
(i.e. the prediction) of the phenomenon, the process or the object are output.
As a future situation related to the anthropogenic effect depends on many factors of stochastic origin and is
characterized by uncertainty, the method of maximum likelihood has appeared to
be suitable for this case. The abovementioned method is based on the
probabilistic approach. The analysis and the estimation of predicted parameters
of anthropogenic factors are often multiple-factor and are associated with
elimination of uncertainty. This requires the application of the system
approach and the corresponding body of mathematics.

SUMMARY
The algorithm of network decomposition in tree-type structures
Gogichaishvili
G.G., Meparishvili B.D. and Janelidze G.N.
Among a lot of problems of management of industrial
projects with network structures (water, gas and power supply systems), there
is a problem of optimal distribution of material flows. Based on the specific
character of the project, its structure should exclude any cycles and loops,
i.e. its system must be represented in the form of independent tree-type
structures, the roots of which are the outflows. These trees must complement
each other so that no branch should fall out of the field of consideration.
Fluctuations of local loads or input flows from the sources, as well as
emergency situations, establish the conditions of dynamic regeneration of tree
structures and, thus, of redistribution of the flows in the branches of those
trees, which complicates significantly
the management tasks. There is proposed an algorithm of network
decomposition in tree-type structures. This algorithm is recursive, and, to a
certain extent, it is related to the algorithm of finding the spanning set
tree, though differing from it significantly.
Keywords: algorithm, network decomposition, tree-type structure,
management of industrial project.

systems
Kobakhidze
T.D.
The analysis of possible versions of monophase
correctors of the power factor has shown that power factor correctors with
high-frequency transformation and two versions of feedback circuit with
multiplication and integration are preferable. The version with multiplication
provides simple realization of a double-loop control system, and it can be
created on the base of digital or analog means. The version with integration
allows simple realization of a single-loop control system.

The goal of the work was the thermodynamic
investigation of system B2O3-C for a wide temperature
range and gas phase pressure. The thermodynamics of the involved processes was
simulated with the help of a computer using up-to-date thermodynamic data and
efficient software. As a result, the optimal conditions of production of boron
and its carbide were established for a wide range of component ratios. The
temperature of beginning of interactions in the system was determined. The
effect of gas phase pressure on the yield of condensed substances at different
temperatures and initial component ratios was studied. During the thermodynamic
analysis of system B2O3-C, for the gas phase pressure of
10.1 kPa and 1.01 MPa, there were constructed phase diagrams which allowed
predicting the optimal conditions of corresponding processes and drawing up the
justified notions of their mechanism
