Role of Photoelectrons Capture on Neutral Centers in the Formation of Distribution Function
Presented by Corr. Member of the Academy T.Sanadze, June 19, 1997
ABSTRACT. We report here an investigation of a type of distribution (DF) of hot photoelectrons while captured on neutral centers and the influence of inverse distribution function on behaviour of kinetic coefficients. It has been obtained that inversity of DF is determined by energetic dependence of lifetime (tcn(e)) for the indicated p mechanism of capture. It is shown that <tcn> is increasing function of fotoelectrons (e0) excitation energy and at big e0 it goes out to saturation.

Presented by Academician N.N.Nutsubidze, July 16, 1997
ABSTRACT. The study of pigments content of spontaneous wheat-rye amphidiploids and their parent forms have shown that some investigated Triticale exceed parent forms in the content of pigments in a flag , awns and earscales in all phenological phases .The intensity of photosynthesis in wheat-rye amphidiploids at phase of milk stage ripeness, several times as much as that in the parent forms. While the intensity of the respiration all phenological phases of amphidiploids is less than in parent forms. Therefore in amphidiploids parallel with the increase of photosynthesis intensity the reduction of expenditure on respiration allowing to use these forms for subsequent selection.

Emotional Words Influence on Human Recognition Learning
Presented by Academician T.Oniani, May 13, 1997
ABSTRACT. To investigate the number of correct responses (NCR), the reaction time (RT), the effects of positive and negative verbal reinforcement on the visuo-spatial recognition learning of geometric figures in condition of backward masking were studied in healthy subjects and patients with chronic alcoholism. It has been found that in performance of mentally constructing geometric figures negative verbal reinforcement unlike positive reinforcement, produce an emotion reaction which may cause the worsening in recognition learning in alcoholics. The verbal feedback mechanisms of reinforcement play an important role in the dynamic changes in the hemispheric lateralization of the human brain.

Distribution of Acidic and Basic Amino Acids in Two-Stranded Coiled-Coil Sequences
Presented March 25, 1997
Abstract. Considering the hypothesis of randomity distributions of charged amino acids in two stranded coiled-coil sequences have been studied. The normality of distributions was evaluated by Pirsonís c2 criterion. It has been found that, distributions of charged amino acid's in coiled-coil sequences are normal. Exceptions are Glu distribution in type II keratin and Glu and Lys distributions in S2 myosins.Thus we can say that the phenomenon of existing only in S2 myosins sequences of short, rich with negatively charged amino acid fragments is the result of ubnormality of the Glu and Lys distributions. Hence this phenomenon must be considered as the result of naturally determined process.

Evalution of the Mechanisms of Water Samples' Membranotropic Effects as Evidenced by the Electroplasmographic Analysis
Presented by Academician T. Oniani, May 6, 1997
Abstract. In a framework of the model, which describes potential-dependency of the velocity of cellular cyclosis in the characeae algae, the evaluation of the action character of the tested water samples was performed. It was found that, according to their action on the cyclosis, tested water samples clearly differ from each other. They exert direct action through the changes of the resting potential and indirect - through the shifts, which are due to the structures responsible for the cyclosis. According to the obtained regularities it seems feasible to recommend the use of elaborated procedures in the system of biological testing of the water environment quality.

Henís Brain Lectins at Different Stages of Embryo Development
Presented March 6,1997
Abstract. In the henís brain embryo some lectins specific to lactose and galactose have been discovered. We have studied the quantitative distribution at embryo development. It is shown that the activity of the lectins is higher at earlier stages of embryo development, in particular, on the 5-8th days, on the next stages its activity decreases. The lectin shows the maximum of the activity in the range pH 7.4-8.0. The lectin can be dissected from the brain homogenate when it is saturated with amonium sulphate at 80-40%. It keeps its activity in the non-frozen state until the 14-15th day.

Presented by Academician T. Dekanosidze, June 26, 1997.
ABSTRACT. The intensity of lipid peroxidation process and its influence on the cellular metabolism in crush syndrome was studied by electrone paramagnetic resonanse (EPR) method.
Obtained data provide us with an opportunity to conclude, that at the early stages of crush syndrome (1.5 hr) in the organism of animals occurs activation of lipid peroxidation, destruction of membrane structures, which then results in disturbance of electrone transport in mitochondria in NAD.H:ubiquinone-oxido-reductaze section, destruction and inactivation of enzyme complexes(cytochrome P-450 and ribonucleotid reductaze) and marked decrease in intensity of proliferative processes.

Presented by Academician L.Gabunia, February 24, 1997
ABSTRACT. The joint archaeological and palynological study of the cultural layer of the settlement in Shiraki dated back to VII and VI c.B.C.showed that vegetation and climate of that time differed strongly not only from the modern ones but also from those of ancient and Rome time. In the VII c.B.C. there was a spread of forest - steppe landscapes to the Shiraki valley, while the climate was characterized by higher humidity than nowadays. Hydronetwork was also well developed.

Lexical Borrowings Meaning Evil Spirit in Georgian and Russian Translations of the Bible
Presented by Corr. Member R.Gordeziani, July 17, 1997
ABSTRACT. Narration about struggle against evil spirits is an integral part of the Bible texts. But types of segmentation of this lexical sphere for Russian and Georgian languages are different.
The investigation shows that this divergence is explained by the peculiarities of religious thinking of Georgian and Russian peoples, their previous experience of life, fixed in their languages.
The Ritual of Sacrifice in the "Odyssey"
Presented by Corr. Member of the Academy R.Gordeziani, July 16, 1997
ABSTRACT. For a long time attention has been paid in Homerology to the "Kingdom of Souls" of the "Odyssey". Not less important than the textual questions is actual the ritual described in Nekyia. According to the text, in the scene of the kingdom of souls of the "Odyssey" we can distinguish four stages. We are interested, which considerations are connected with progressing through particular stages: 1)drawing blood from a victim and 2)burning the skin of the victim. We hypothesize that it is necessary to carry out these two stages in order for a soul to have partial communion with the power of life. In our opinion blood is the power of earthly life; skin has fur or hair or feathers, in which according to ancient peoples, there should be the power of life.
