An Implicit Signorini's Problem in the Theory of Elasticity
Presented by Academician T. Burchuladze,
ABSTRACT. The question
of the uniqueness of the solution of the implicit Signorini's problem of a
general elliptic differential equation with variable coefficients of second
order is investigated. The result is generalized for the systems of the theory
of elasticity in the case of anisotropic inhomogeneous elastic media. The
investigation is based on the study of the problem of uniqueness of a fixed
point of some
F:R+ —> R+
mapping.
It is proved that F is
the function from the Lipschitz class, which for sufficiently small barriers
has a unique fixed point. The necessary and sufficient condition for the
uniqueness of the solution of the problem is established.

ABSTRACT. The equation

into account inertial and elastic forces was analyzed. It's demonstrated that
in case of rejecting the variable component of an inelastic resistance
coefficient, the constrained vibrations of a system "destructing

ABSTRACT. The dynamic
model of neuroreceptors functioning in synapses is proposed in this work.
Charged groups of the mediator molecule are shown to induce polarization
effects on the receptor molecule, that in its turn cause deformations of

ABSTRACT. The problem
about a giant magnetostriction of monochalcogenides is connected with their
giant anisotropy. We propose the possible mechanism of the giant
magnetostriction arising into monochalcogenides and monopnictides. We studied
uranium monosulphur and uranium monophosphide. The uranium monopnictides and
monochalcogenides have NaCI-type structure, so that the magnetic ions fall on

ABSTRACT. The method of
auxiliary sources (MASS) has been extensively applied to the wide class of
steady electromagnetic processes problems as one of the efficient tools. The
extension of MASS into time domain is presented in this paper. It provides the

ABSTRACT. High-manganese
oxide glassy semiconductors (OGS) of the system ÑàÎ-Â2Îç-ÌïÎ-ÌïÎ2 were synthesized. Experimental
studies have shown that high-manganese OGS elements are switched from high to
the low resistance state under the effect of high electrical fields (105
Vcm-1) It was established that OGS of molar composition 2ÑàÎ-ÇÂ20ç-2ÌïÎ-2ÌïÎã has an optimum electrophysical
properties and following coordination groups:
[Ca2+O2/2].[B3+O3/2].[B3+O4/2]-1.[Mn2+O2/2].[Mn2+O6/2]-4.[Mn4+O4/2]
could be entered this
OGS.
Thus, high-manganese OGS

Conditions of Formation
Presented by Academician N.Skhirtladze, July 21, 1997
ABSTRACT. The
investigations show that phenocrystals of studied pyroxenes are homogeneous,
their formation took place on deep horizons of the Earth's crust in aqueous
medium of high temperature (1052 - 1375°C) and under pressure (l,9k.bar
- 11.7k.bar)- The mineralforming temperature caused such
characteristics of pyroxene as: Ca, Mg , Fe, specifically the increase of
temperature caused Ca reduction and Mg , Fe increase and vice versa. The rock
solidification coefficient < mineral solidification coefficient indicates
that the formation of mineral took place earlier than that of the rock as its
final form. It makes possible to suppose that the formation of minerals
happened as a result of ferrugenous melt crystallization in closed system
without any sharp changes in T and P conditions

Study of Cortisol Effect on Genome Expression of Steroid
Target Cells in Adult and Growing Rat Tissues
Presented January 23,1998
ABSTRACT. This paper
presents a study of the cortisol regulatory influence on RNA-synthesis
intensify of steroid target cells in adult and growing (one month old) white
rats. Stimulatory effect of one-(0.1mg/g) and three fold (0.3mg/g) cortisol
injection on RNA-synthesis was demonstrated in hepatocytes of both adult and
one month old animals. At the same time, cortisol performed opposite effect on
the transcriptional activity of kidney epithcliocyte nuclei. Based on the
published data, we suggested that different influence of cortisol on target
genes is due to the variations in the relative distribution of 11b -dehydrogenase and 11b -oxoreductase activities in these
tissues. Also, the obtained results indicate that cytostatic effect of cortisol
on genes regulators of cell proliferation active in hepatocytes stimulated for
proliferation is a phenomemon specific to the compensatory growth.

Inhibition of Bee Venom Phospholipase A2 Activity by
"Plaferon LB"
Presented December 31,1997
ABSTRACT. The effect of
human placenta peptide enriched preparation with immunomodulatory and
antiinflammatory properties "Plaferon LB" on Âåñ Venom Phospholipase A2 (PLA2) was
studied. "Plaferon LB" standard therapeutic dose inhibited PLA2
activity (substrate - I-a -lecithin) of whole dried bee venom
by more than 90%. This inhibition was time dependent and reached the plateau
after 10 min of "Plaferon LB" preincubation with bee venom.
"Plaferon LB" caused significant reduction of PLA2 activity even
after 100-fold dilution of standard dose. The Lineweaver-Burk analysis showed
that the reaction catalyzed by bee venom PLA2 was inhibited by our placental
preparation via noncompetitive mechanism.
These data permit to
assume the presence of noncompetitive peptide inhibitors of secretory PLA2 in
human placenta.

The Role of Changeable Metre in B.Kvernadze's Instrumental
Music
Presented by Academician V. Beridze, January 21, 1998
ABSTRACT. Metre
changeability in B. Kvernadze's creative work is mainly connected with
dynamism, and this phenomenon, in its turn is related primarily to Georgian
folk music. Metre and rhythm expressive function in composers' works represent
not only the expression of general tendency, but also generalization of the
traditions in national folk musical creation. Metre change has several impulses
at the same time. It can be connected with form, content, genre peculiarities and
with a dancing element specifically.
