Solution of Some Special Boundary Problems of the Elasticity Theory in Cylindrical Coordinates

Presented by Academician T. Burchuladze, December 13, 1997

ABSTRACT. Elastic equilibrium of a body bounded by the surfaces of the coordinates of the cylindrical system r, a, z (0 £ r < ¥, 0 £ a < 2p, -¥ < z < ¥) in the area W = {r0 £ r < r1, 0 < a < p, 0 < z < z1} is considered. It is proved that special conditions given on cylindrical surfaces of the body admit continuous extension of the solution from the cylindrical boundary surface along its normal (along the radial coordinate) at the appropriate perturbation of the surfaces z = 0 and z = z1, when the conditions of antisymmetry are given on the surface a = 0, and the conditions of symmetry on the surface a = p.

Diffraction of a Plane Electromagnetic Wave by the Edges of Parallel Infinite Slot

Presented by Corr. Member of the Academy T. Sanadze, April 17, 1997

Abstract. Based on the rigorous mathematical approach, the approximate solution is obtained for the problem of diffraction of the plane oblique incident electromagnetic wave by the edges of the parallel infinitive slot. This solution tends to the exact one with the increase of transaction factor of obtained infinitive system of algebraic equations.

The function j(a0, a) characterizing the directional pattern of the slot is computed. It is shown that this function satisfies the arrangement condition j(a, a0) = = j(-a0, a) and boundary conditions j(a0, ±1)=0 and j(±1, a) = 0, where a0 = siny0, a = siny, y0 is the incidence angle and y is the observation point polar angle.

The Variability and Distribution of the Total Atmospheric Ozone in Georgia

Presented by Academician B. Balavadze, May 30, 1997

Abstract. The paper examines the peculiarities of the total atmospheric ozone variability in 1973 - 1995 from three observational points: Georgian (Abastumani, Tbilisi) and Russian (Kuibishev). It has been concluded that at the mentioned points a tendency towards decreasing of the total atmospheric ozone is present and the decrease in Tbilisi has amounted to 5% for the last 20 years, 3.8% in Abastumani and 5.2% in Kuibishev. It is noteworthy that a similar decrease in the total atmospheric ozone of higher or lower intensity is observed throughout the world. The decrease of the total ozone is caused mainly by the anthropogenic environmental pollution. Using the obtained data, maps of the mean annual and mean seasonal distribution of the total ozone have been composed.

The Field-Activated Combustion Synthesis in W-Si System

Presented May 12, 1997

Abstract. Tungsten silicides have been investigated using the activation of the self-propagating high-temperature synthesis (SHS) process through the application of an electric field for compositions ranging from 6 to 30wt% Si. It was shown that initiation of the propagation process of a combustion wave could be fulfilled through the threshold value of the electric field strength. The value of applied field strength may influence the mechanism of silicide formation. The silicide W5Si3 is believed to be synthesized under the influence of a high field only. The silicide WSi2, however, can be synthesized with field activation both at low and high field values.

Presented July 16, 1997

ABSTRACT. In the article the new data are given about the interrelation of the granitoid dyke-shaped body, located on the southern slope of the Abkhazian part of the Greater Caucasus, namely at the head of Atsgara river, with the Middle-Upper Liassic country rocks. From the two existing opinions about the age and occurrence of the granitoids: the Middle Jurassic sintectogenic intrusion or a tectonic wedge of the Pre-Alpine basement - the first one is considered to be justified. The formation of the intrusion is explained by squeezing mechanism of the Hercynian crystalline basement’s eutetic melting.

The Effect of Phytohormones on Photosynthetic Intensity and Stomatal Conductivity in Grapevine

Presented by Academician G. Sanadze, June 17, 1997

Abstract. The effect of indoleacetic acid (IAA), benzylaminopurine (BAP), and abscisic acid (ABA) on photosynthetic intensity of grapevine leaf and relationship between the plant organs in different phases of vegetation was studied. The influence of phytohormones on stomatal conductivity was investigated. Application of all growth regulatores on leaves Pi=5-6 or clusters of Vitis vinifera L., Variety Rkatsiteli, intensifies the photosynthetic activity of leaves, especially in the case of cluster treatment which causes more essential alteration in source-sink relations. BAP and IAA considerably increased stomatal conductivity, while ABA decreased it.

Presented by Academician T. Oniani, June 11, 1997

ABSTRACT. Comparative study of blood circulation at modelling of informational pathology by various methods were provided. Different changes of pulse and pressure dynamics of experimental animals (white rats) were observed. In case of testing of animals by a direct method of deferred reactions of short-term memory, dynamics of pressure and pulse changes was not altered. At testing the animals by indirect methods, regulation of the named parameters were altered, that was manifested in their periodic deviations from stable levels (either increasing or decreasing). At informational overloading of defense conditional reflex memory similar changes of pulse and pressure were observed, but in this case limits of change of pressure and the frequencies of pulse were much wider.

Localization and Spatial Distribution of Ribosomal-Genes Transcription Sites in Certain Tissue Cells Nucleoli in situ

Presented October 2, 1997

Abstract. Spatial arrangement of the localization and transcription sites of ribosomal RNA-genes have been studied in ring-shaped nucleoli of liver capillary endotheliocytes and reticular nucleoli of kidney proximal tubules epitheliocytes of the guinea-pig. It has been shown that active sites of r-genes are not equally distributed even within one fibrillar centre and the areas of their localization design the topography of dense fibrillar component. Inactive sites of r-genes are mainly localized in intranucleolar condensed chromatin on the surface of adjoining fibrillar centres. In a moderately active reticular nucleolus active sites of r-genes are simultaneously activated with the fragmentation of the fibrillar centres, being distributed over the surfaces of the fibrillar centres and dense fibrillar component strands.
