An Implicit Signorini's Problem in the Theory of Elasticity

Presented by Academician T. Burchuladze, October 20, 1997

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.

Study of the Strained State of a Destructing Instrument in the Forming Shock Pulse Process

Presented by Academician K.Betaneli, February 19, 1998

ABSTRACT. The equation for the vibration of a system "destruction instrument-rock", taking 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 instrument-rock" can originate not exclusively with the frequency of the harmonic external action.

Presented June 6,1997

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 the fcc lattice.

Meskheti Top North Slope (Tsablaristskali-Zvarulas River Spacing) Pyroxene Crystallochemistri, Minal Composition and Thermodynamic 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 - 1375C) 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

Influence of Acidic Precipitation on Nitrogen Metabolism of some Vegetables and Crops

Presented by Corr. Member of the Academy N.Nutsubidze, 31 July, 1997

ABSTRACT. The effect of spraying of acid solutions on total nitrogen, nitrates, free amino acids content and the activity of enzyme nitratreductase was studied on maize, kidneybean, dill, parsley, coriander, onion, eggplant, pepper, carrot and beet. The solutions of H2SO4, HNO3, HCL with proportions 1:1:1, pH = 2.0-2.5 were used. It was shown, that spraying increases nitrogen metabolism, while the content of nitrates keeps to limited level. The changes may be caused by the essential activation of nitratreductase.

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 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.
