Abstract. In the present note we investigate noncommutative linear polynomials over H. It is shown that the Fundamental Theorem of Algebra is not valid for them; more exactly, there takes place the trichotomy, i.e., either the polynomial of the type , where , has the unique root, or P^-1(0) is empty, or P^-1(0) is an infinite set. The corresponding examples are given.

For holomorphic principal bundles on Riemann surfaces their holomorphic type is introduced as a vector of integers, and it is shown that the sum of its components equals the characteristic number of the bundle. It is also shown that the holomorphic type of a holomorphic subbundle depends on the holomorphic type of the ambient bundle via certain condition; this is used to derive necessity of stability of subbundles of stable bundles.

Certain Distribution of Planets on Heavenly Sphere at the Moment of the Earthquake as a Triggering Effect (Combined Model)

Presented by Member of the Academy V.Chavchanidze, September 25, 2001

Abstract. This work is devoted to numerical modelling of the fuzzy organization of different structures in planet locations distribution at the moment of earthquake. It is the case when the use of statistical methods or theory of errors do not give satisfactory results. The reason is contained in the nature of data and methods of their representation and processing. When data are presented by vague and overlapping intervals and in the process of receiving the information an expert participate, nature of data will be combined: in parallel to a probabilistic-statistical uncertainty there also exists a possibilistic uncertainty. Taking into account the combined nature of uncertainty above distributions are characterized by possibilistic spectrum describing emergence mechanisms of different structures.

Multielement Instrumental Neutron Activation Analysis of Biological Materials Using "Breeder ÏÑ-1" System

Presented by Member of the Academy G. Kharadze, December 18, 2001

Abstract. We have studied the possibility of using neutron source "Breeder ÏÑ-1" in plants for multielement instrumental neutron activation analysis (INAA). We propose the method of multielement INAA in vegetable samples for the following elements: Na, Mg, Al, Cl, K, Ca, Mn, Cu, Zn, Br, Rb, Mo, I, Ba. For numeric determination of the given elements the necessary sensitivity makes 10^-5-10^-3 g/kg on dry biomass. To reach the mentioned sensitivity the concentration of the analysed materials was performed which was realized by lyophylic drying and then by compression under high pressure. In order to irradiate the samples neutrons integral flow was used within the range of 10⁹-10¹¹ neutron/cm².

The g spectrometric measurements were done by means of Ge(Li) semiconductor detector and impulse amplitude analysator AH-1024.

Quasi-Biennial Variations of the Stratosphere Ozone and Solar Activity

Presented by Corr. Member of the Academy R.Kiladze, October 30, 2001

Abstract. Some regularities of quasi-biennial oscillation (QBO) of the stratosphere ozone are investigated on the basis of the ozone total content data (OTC) obtained at the Abastumani Astrophysical Observatory in 1957-2000. It is shown that they are connected with quasi-biennial variatons of the solar activity and form a fading wave train of fluctuations within the limits of the solar activity cycle. The wave train arises during a minimum of the solar activity. Within a maximum of the solar activity the period of fluctuations is about 36 months and it decreases linearly to ~ 24 months to the end of the 11-year cycle.

Abstract. In this paper, we theoretically proved the existence and nature of those atmospheric processes, which can be observed in operation practice but the reasons of which origin are unknown. These processes are mainly conditioned by microregional peculiarities of Transcaucasian mountain relief and they are described by the system of hydrothermodynamic equations. With requirement of determining boundary conditions the solution of vortex wind velocity (in x, z plane) was obtained. This solution makes possible to study local atmospheric processes dominating on the small territory.

On Application of Plants (Coreopsis lanceolata L.) in Pharmacological Research by Determination of their Electric Conductivity

Presented by Corr. Member of the Academy A. Asatiani, November 13, 2001

Abstract. The experiment was based on the estimation of the electric resistance of the plant - Coreopsis lanceolata L. The resistance of the investigated stems was determined by their conductivity (the alternative voltage of 220 V). The plants were placed in the vessel with distilled water - the solvent of pharmacologically active substances. Spasmolytic drug Noshpa that is active in the case of animal organisms has the similar influence on plants (Coreopsis lanceolata L.) . Calcium blocator Isoptin active in case of animal organism shows the similar effects in the case of plants (Coreopsis). The results obtained make it possible to suppose, that the plant cells possess the receptors acting the similar way as the receptors of animal cells. According to these results we can suppose that using the plants one can essentially expand the area of biological objects in the pharmacological investigations.

Influence of Genotype on Drosophila Lifespan

Presented by Member of the Academy N. Javakhishvili

Abstract. Significance of DNA repair ability for Drosophila lifespan has been studied using two strains of Drosophila melanogaster: the radiosensitive mutant rad201^G1 and the radioresistant one. The results of observations in which the experimental objects were not subjected to the action of environmental factors are presented.

An average lifespan turned out to be shortest in the females of radiosensitive strain. Lifespan of mutant strain females is characterized by variability. Lethal effect of radiosensitive gene varied at different stages of ontognesis. This effect seems to be conditioned by cytogenetic structure of the chromosome segment containing the rad 201 gene.
