Ambiguity of Determination of the Electrical and the Magnetic Specific Polarization of the Condensed Medium

Presented by Member of the Academy G.Kharadze, December 7, 1998

Abstract. The transition from potentials to field strengths in the Hamiltonian and the current density permits us to express the current density operator in terms of the electrical and the magnetic specific polarization operators. It is important that the current density J is expressed by vectors P and M, which are the quantum-mechanical averages of the corresponding operators and consequently are well defined within the microscopic theory quantities.

Quasicontinuous Laser Plasma in the Process of Interaction of Train of Giant Pulses with Solid Target

Presented April 5, 1999

Abstract. By interaction of train of giant pulses of the high-power waveguide neodymium laser (with pulse repetition rate up to 100 kHz, with total energy up to 30 J) the quasicontinuous laser plasma by duration up to 0.2 msec is obtained. In plasma - air boundary layer the stimulated Raman scattering of laser radiation takes place, which demonstrates that in this area the products of carbon burning CO and CO2 testifies. The velocity of distribution of a plasma surface is measured. The process of burning of plasma essentially reduces the process of plasma cooling.

Method of Statistical Collection in the Local Network

Presented by Member of the Academy N. Amaglobeli, July 8, 1998

Abstract. NetBlazer’s software is able to create efficiently interfaces for the customers who are connected via modems in the network. NetBlazer's software provides different pryorities for customers to work with net’s software resources.

After complete describing one can monitor the statistics of transferred and received informational packages on the NetBlazer. It will be a fixed described information on the time of connection and break out: year, month, day, hour, second. It should be mentioned that only this way (sending information from NetBlazer to Name Server) could be registered statistics of dynamical users. It is program product (on C, C++ languages) created on the operating system of Name Server. This product allows us to represent network loading via interfaces and in the desirable way.

The advantage of accumulation of users statistics is that in case of NetBlazer’s breaking the necessary information would be saved as a file on network server.

Influence of Acidic Rains on the Activity of Plant Endogenous Growth Regulators

Presented by Corr. Member of the Academy N.Nutsubidze, May 18, 1998

Abstract. We studied the effect of artificial acidic rains on the activity of endogenous growth regulators of the following plants: red beet (Beta vulgaris L, ssp esculenta),onion (Allium cepa L), carrot-(Daucus sativus (hoffm) Bochl), coriander (Coriandrum sativum L), kidney bean (phaseolus vulgaris L, savi), dill (Anethum graveolens),maize- Zea mays L. It was revealed, that acidic rains cause activation of auxin group substances in the sprayed leaves of onion, bean and maize. Comparatively high level of inhibitors was found in sprayed variants of beet, carrot, dill and coriander. In underground parts of beet, carrot, onion and in seeds of bean the difference between sprayed and control variants was not observed. Distinctions in results may be explained by the differences in acidic salts uptake and accumulation, affecting period and plant’s biological peculiarities. It indicates different mechanisms of adaptation to acidic rains in plants.

Abstract. For the purpose of clarification of interdependence in the depot system - the circulation within the framework of an original methodical approach distinctive shifts in populaton spectrum (PS) of peripheral blood erythrocytes (PBE) were explored in rats under the influence of a stress factor and in the immediate post stress period. It has been established that deposition of blood is a causally stipulated, genetically determined process. It has been also revealed that in the blood depot only young erythrocytes are accumulated. Reversible deposition of cells of intermediate age and old erythrocytes are not noted.

The Effect of Interchain Disulphide Cross-Link in the Tropomyosin Molecule on the Process of Actomyosin Contraction

Presented May 4, 1998

Abstract. The effect of interchain disulphide cross-links and blocking of cystein-190 in the rabbit muscle tropomyosin molecule on the potentiation of actomyosin contraction by tropomyosin has been studied. The disulphide crossband between tropomyosin a and b subunits changes tropomyosin conformation in the way that weakens F-actin - tropomyosin interaction; the blocking of cystein-190 causes the losing of polymerization ability; the cooperativity of Ca2+ regulation of actin-myosin interaction by troponin-tropomyosin complex diminishes.

We have shown that interchain disulphide cross-links and blocking of cystein 190 in tropomyosin molecule doesn’t effect the potentiation of actomyosin contraction by tropomyosin. The conclusion was made that the districts responsible for the tropomyosin participation in Ca2+ -regulating mechanism and activation of actomyosin contraction in the tropomyosin molecules must be different.

Investigation of Blood Lipids and Fatty Acids in Benign Prostate Hyperplasia and Prostate Adenocarcinoma

Presented by Corr. Member of the Academy N.Aleksidze, January 4, 1999

Abstract. Quantitative alterations and lipids’ peroxide oxidation (LPO) of the human blood phospholipids, cholesterol, and fatty acids have been investigated in healthy donors and patients with benign prostate hyperplasia (BPH) and prostate adenocarcinoma (PAC). It was found that in the blood of the PAC patients an overall volume of phospholipids and of amine-containing and choline-containing phospholipids was sharply increased. In both pathologies an increase of cholesterol and activation of the LPO was evident, although in the malignant tumors these indices were higher. As to fatty acids, in PAC a sharp decrease of oleic and palmitic acids was determined, while stearic, linolenic, and arachidonic acids’ volume was increased. All these data point to the systemic character of the tumor action.

Dynamic Regulation of Light Absorption in Plants during Stress and Acclimation

Presented by Corr. Member of the Academy T. Zaalishvili, May 31, 1999

Abstract. After low-temperature stress and rewarming, if the stress-induced damage is not irreversible, a noticeable increase of delayed thylakoid fluorescence is marked compared with the level prior to stress. It indicates temporal depression of photosynthesis dynamic regulation mechanism, while the thylakoid membrane can still produce the transmembrane gradient of protons. Dynamic regulation mechanism depression must have been induced by the dehydration factor of low-tempetarure stress. The mentioned mechanism is very sensitive to this factor. After cold acclimation of the plant the low-temperature stress causes neither temporal depression of dynamic regulation mechanism nor intensification of delayed fluorescence.

Heart Trophic Ultrastructural Basis under Experimental

Presented by Member of the Academy N. Javakhishvili , March 29, 1999.

Abstract. We have studied ultrastructural-functional changes in the heart from an early period of atherogenesis (14 days) to its late period (6 months) in rabbits hypercholesterolemic model. The results revealed that morphofunctional changes in microcirculatory network of the heart are caused by degenerative changes in capillary endotheliocytes, fibroblasts collagen and GAG production. Such alterations as a whole result in the profound changes in myocardiocytes structure and function and development of diffused small focal cardiosclerosis.
