The results of the
investigation of oxygen films and binary oxygen and cesium films on the
gas-phase polycrystalline tungsten coating of NB-1%Zr alloy demonstrated that
such a coating possesses rather the properties of W-Nb alloy than of pure W.
All the specific features distinguishing this coating from the homogeneous one
are. related with the diffusion of Nb onto the surface. With account for oxygen
which is not removed till the temperature reaches 18000C, on smooth
and the most perfect areas of the lower level, there exits at least three-level
relief of the substrate of the film of intermetallic suboxide Nb2W2O.
Such a film, which has a three-dimensional structure with maximum saturation of
metal-oxygen chemical bonds, prevents both further segregation of Nb on the
surface and further oxidation of Nb and also W which is not bound to Nb, i.e.
it leads to formation of heat-resisting coating.
Keywords: tungsten coating,
niobium-zirconium alloy, cesium, oxidation.

Zykov B.M. and

Sukhumi Institute of Physics and Technology
Despite the fact that the film of Nb2W2O
itself is optimal for cesium, the presence of carbon and W2C, which
cannot be removed, in the material of the specimen and CO and COCs they form
with oxygen and oxygen and cesium, respectively, causes the formation of other
nonoptimal compounds with cesium: NbCOCs – at the lower level of the
relief and W2COCs – at the upper one. These compounds have
almost the same heat resistance as the optimal film of sub-bronze NbW2OCs
at the lower level. As a result, φmin with Cs becomes by 1.6 eV higher that that for pure
monocrystalline W, Nb and Mo-Nb alloy. What this means is the thermion
collector (TIC) from this material can operate maximum 50 percent of its
capacity in spite of stability of basic properties of the films with Cs in wide
temperature ranges of oxidation and warming-up. Hence it is necessary to take
measures for decreasing the amount of carbon in the material which the TIC is
made from in order to improve its efficiency.

THE EFFECT OF
MEASURING INSTRUMENTATION ERRORS ON SOME PROPERTIES OF SECOND-ORDER ASYMMETRIC
DESIGNS
Zedginidze
I.G. and Beraia N.O.
For determination of factor levels in accordance
with the design, various instruments, having this or that inaccuracy, are used.
The effect of the most typical errors on some properties of second-order
asymmetric composition designs for two, three and four variables were studied.
In particular, there was studied the abovementioned effect on the designs which
are the closest to the optimal ones from the standpoint of the minimum of
maximum dispersion of parameter estimations and the minimum of dispersion
variations of parameter estimations. The mechanism of simulation of various
errors and their superimposement on the corresponding coordinates of the
designs is described. By each of the criteria for different number of the
factors under study, the corridors of errors were determined. It is
demonstrated that as the error increases, the arithmetic average and the spread
in values change. Based on the investigation results, it was inferred that it
is possible to determine the optimum value of the “star” arm with
less accuracy: not with three places after the point, as it usually takes place,
but using only one or two places after the point. It is demonstrated that round
off to the nearest tenth in the case of two factors under study makes the
asymmetric composition designs be closer to the optimal ones from the
standpoint of both criteria considered.

COULD THE
RECOGNITION OF THE PARADOX OF DUALITY of
SCIENCE AND RELIGION SERVE FOR CREATION OF THE GENERAL THEORY OF GREAT

Khvedelidze
M.A.
The author of this work presents a brief analysis of
the book Brief History of Time from the Big Bang to Black Holes by
phenomenal English physicist-theorist Stephen W.Hawking (Russian translation,
Moscow,Mir,1990). The goal of the analysis is expressed in the title of the
present work, and, for answering the question posed, the inferences made by
Prof.Stephen W. Hawking himself are cited. There are also cited the ideas
suggested by Prof. Charles Sagan, Cornwell University, the USA, and Prof.
J.A.Smorodinski, Russia, in their prefaces to the book. This justifies the
professional competence of all three physicists-theorists and the author of the
present work, a cybernetist-informationologist, for seeking the answer to the
question posed in the title of the work.
It is beyond question that modern science has
approached the limit of knowledge about the Universe, which was recognized to
be without the beginning and the end in time. Thus, if the man could live till
the state of immortality, i.e. the state of the Superior Mind - the God, as a
result of rather long-term natural selection, his really infinite time and his
boundless labor would allow him to expand significantly the limits of knowledge
about the largest and the most complex system - the Universe. In this respect the
presented analysis seems promising as a
resolution of the next paradox of science and religion, which will be
discussed in the further work.

Ball lightning – a problem of science of
fundamental significance
Berria G. N.
M. Nodia Institute of Geophysics
The 9-th International Symposium
on the Ball Lightning has shown once again that this phenomenon constructs a
paradoxical problem for science: almost all is already known about the ball lightning.
About 120 of its elementary properties were established, hundreds hypotheses
were created, but, however, its nature remains to be a mystery. A great number of
known properties and hypotheses allowed conducting the analytical study, and it was established
that the majority of the hypotheses contain anomalies (noncompatibility with the
properties) and, consequently, settle out of the agenda of the challengers to
the solution of the problem. Only a
small part of hypotheses is free from anomalies, they are referred to the
theory of electromagnetic field.
The paradoxical delay of the solution of the problem is explained not by the
complexity of the task, but by its
fundamentality. For its solution, it is necessary to change considerably our
understanding of the structure of the Universe.
Keywords: ball lighting, fundamental problem, hypothesis,
paradox.
On the basis of equilibrium concentrations and corresponding
temperature data, obtained by experiments, a set of equations, which reflects
chemical (volumetric) potentials, was developed. Five-member interaction
coefficients for binary subsystems of Ti-Ni-Cr alloys were calculated by means
of these equations. For the purpose of checking the accuracy of the obtained
values, the theoretical and experimental phase diagrams of Ti-8Ni-Cr- system
alloys were compared. As a result, it was established that the diagram built by
the five-member coefficients of binary interaction is more precise than the one
obtained by the binary coefficients, which exist in the database, and that it
coincides with the diagram obtained experimentally.

For modeling of the corrosion behaviour of Ti-8Ni-Cr system alloys there were used the statistical
methods of regression
analysis: fractional factor
experiment 24-1, the Box- Wilson design and the second-order composite-rotatable design. The effect
of chromium content in the alloy, the pH values, the experiment duration and
the temperature of thermal treatment
were studied. An adequate linear model of corrosion rate y=0.1178+0.0636x1-0.081x2,
where only two factors are significant – the chromium content and the
temperature of thermal treatment, were obtained. After the optimization of the adequate
regression equation of second order, a canonical analysis of the response
surface of optimum was performed. By
comparison of the obtained mathematical model with the hardness and the
microstructure of alloys, the optimal composition of the alloy was established.

For determination of the ultramicroamount of osmium,
the highly sensitive photometric method is selected. The determination of
osmium by this method is carried out with the mixture of reagents (sulfanilic
acid and dimethylaniline) in the nitric acid medium. The proposed method is based
on the catalytic action of osmium. Dimethylaniline reduces nitric acid to
nitrous acid which is determined by
the Griess reaction. The optimum conditions of determining the osmium
were established. A more advanced diagram of analysis was developed on the basis of the
established optimum conditions.

Anniversary of the Foundation of the

International Commission (IEC –
Abstract. It has been established that, the assumption that Faraday’s emf
is always negative and that it resists the change in the electromagnetic
momentum responsible for its generation is wrong. The mathematical
representation of the law of inertia by the negative sign of emf appeared to be
inadequate for representation of the phenomenon of inertia of mutual induction.
This caused significant inconsistency between the theory and the practice,
which have agitated the scientists involved in electrical engineering all over
the world. The emf of mutual induction is negative at positive magnetic
coupling and, in this case, the
change due to which it was generated. On the other hand, the emf of mutual
induction is positive at negative magnetic coupling and it promotes the changes
due to which it was generated. The negative emf is a manifestation of the law of negation of
the change in the electromagnetic momentum, and the positive emf – of
negation of negation. The negation and the negation of negation are physical
bases of magnetic field propagation and energy transfer. The magnetic coupling
between inducing and induced currents is negative. In the present work, the
base reference system, where the right-hand screw orientation of the loop and
the surface was matched with Ampere’s system, was designed. An adequate
formula for the energy of magnetic field of inductively coupled circuits was
derived. Unique notions of like terminals and mutual induction sign were
introduced. A rule of adequate mathematical modeling was developed.

In a number of works, there have been described some devices for revealing and counting

channels free of relevant data. However such measurements are associated with
compulsory interruption of relevant data transfer, which is rather
inconvenient. In the present work, the communication system in which the
adequacy measurement is performed concurrently with the relevant data transfer
via the channel is proposed. In this case, the method of sequential transfer of

obtained at regeneration of Na-cation exchanger with natrium sulphate, the use of is considered. One of the main issues
when using the correspondence criterion (specifically)
is the issue of dividing the sample into the optimal number of grouping
intervals and defining the bound of intervals. The existing methods of dividing
the sample of experimental data into intervals amount to an easy way of manual
counting. However, the division of intervals according to the principle of
equigraphic and equivalent sections

The specific features of growing
and development of new clones of tangerine trees and their phenological phases
are discussed. It was established that the new clones of tangerine trees and
the reference ones underwent the phenological phases in different time. The fruit of these
clones has better indices in reference to the content of Vitamin C, the acidity
and the content of saccharides. Bulk ripening of the fruit takes place earlier,
which allows prolonging the fruit-bearing period by several days.
Keywords: tangerine, clone, phenological phases, biochemical

There was studied the possibility of the use of
frigole powder (FP) and frigole bean powder (FBP) in baking industry. The
powders were introduced at the stage of preparation of scaldings used for
feeding the liquid yeast. The quality of scaldings was assessed at their
souring. It was established that the scaldings prepared with the use of FP and
FBP are a good culture medium for microorganisms. The use of FP and FBP allows
reducing the amount of wheat flour used for scaldings and, at the same time,
improving the quality of the culture medium for liquid yeast and decreasing the
duration of souring. The most effective dose of additive was determined
experimentally.
