On One Estimation of the Regression Curve

Presented March 28, 2006


ABSTRACT. In the present work we consider estimates of a regression function, when the values of the response in the experiment are not observed, and only the values of the indicator function of the event are fixed: “observation does not exceed a threshold”. The limiting distribution of quadratic deviation of the so-constructed estimate of the regression curve is found. © 2006 Bull. Georg. Natl. Acad. Sci. pp. 429-431.

On the Problem of Dynamics of the Ionospheric Wavy Disturbances  in the Shear Flow

Presented by Member of the Academy J. Lominadze, February 22, 2006


Abstract. The generation and further dynamics of planetary magnetized Rossby waves and inertia waves are investigated in the rotating dissipative ionosphere in the presence of a smooth inhomogeneous zonal wind (shear flow). Magnetized Rossby waves appear as a result of the interaction of the medium with the spatially inhomogeneous geomagnetic field and are an ionospheric manifestation of usual tropospheric Rossby waves. An effective linear mechanism responsible for the intensification and mutual transformation of Rossby and inertia waves is found. The nonmodal approach shows that the transformation of wave disturbances in shear flows is due to the nonorthogonality of eigenfunctions of the problem in the conditions of linear dynamics. Thus there arise a new degree of freedom and a new way for the evolution of disturbances in the medium. Using the numerical modeling, we illustrate the peculiar features of the interaction of waves with the background flow, as well as the mutual transformation of wave disturbances in the D-, E- and F-regions of the ionosphere. It is established that the presence of a geomagnetic field, Hall and Pedersen currents in the ionospheric medium improves the interaction and mutual energy exchange between waves and shear flow.  © 2006 Bull.

Presented by Corr. Member of the Academy G. Chagelishvili, January 4, 2006


Abstract. We apply the non-modal approach in combination with numerical calculations to the study of the dynamics of packets of spiral density waves in gaseous disks. To analyze the dynamics of localized (both in ordinary and K-planes) packets of spiral density waves we take a Gaussian packet of short leading waves in K-plane at the initial moment of time. It turns out that the properties of the packet dynamics in physical plane largely depend on the initial location of the packet Fourier transform in K-plane. © 2006 Bull. Georg. Natl. Acad.

Three Dimentional Modeling of the Recurrent Forbush Effect of Galactic Cosmic Rays

Presented by Corr. Member of the Academy T. Chelidze, February 21, 2006


Abstract. Parker’s transport equation is used for modeling of the recurrent Forbush effect of the galactic cosmic ray (GCR) intensity. It is assumed in the model  that the recurrent Forbush effect is caused by changes of the interplanetary magnetic field (IMF) turbulence. Model calculations show that the increase of the exponent of the power spectral density (PSD) of the IMF turbulence leads to the hard rigidity spectrum of the recurrent Forbush effect of GCR intensity. © 2006 Bull.

Production of Electrolytic Manganese Dioxide from Suspension in Conditions of Prolonged Electrolysis

Presented by Member of the Academy J. Japaridze, March 21, 2000


ABSTRACT. The high-temperature (97-98 °C) process of the production of electrolytic manganese dioxide (EMD) from fine-dispersed (5-10 m) MnO2-powder containing aggregatively stable suspension permits the process intensification at the expense of the realization of high anodic current densities (150-200 A·m-2) which is nearly twice as large as the values of anodic  current densities, used in usual method of EMD production.

In the mentioned conditions the titanium anode is not subjected to passivation and the voltage values is held constant in the course of the overall process. The obtained deposits of g-modified EMD are products of  high-purity and the content in them of  MnO2 is up to ~90% [1-4].

For the purpose of the establishment of the stability of  high-temperature suspension bath process of  EMD electrosynthesis the serial experiments of prolonged electrolysis (450 h) were performed on titanium anode. The obtained data show that the use of mentioned process is promising. From suspension solutions of manganese sulfate and sulphuric acid of various concentrations, containing high-dispersed MnO2-powder, the high-quality thick deposits (0.028 m) of g-modified MnO2 were obtained in conditions of stable voltage. © 2006 Bull.

Influence of Irrigation and Drainage on the Environment

Presented by Member of the Academy Ts. Mirtskhoulava, February 27, 2006


ABSTRACT. Irrigation and drainage of agricultural areas drastically change the environment. It can be expressed both by positive and negative influences. The irrigation of grounds in over moistened areas does not change the amount of average long-term flowing. There are distinguished three kinds of hydrological cycles of closed territory: planetary, local and the zone of aeration. One of the negative influences of irrigation on the environment is growth of the volume of return waters. Underground waters actively participate in feeding of the marshlands and swamps in Kolkheti lowland. © 2006 Bull. Georg. Natl. Acad. Sci. pp. 530-532

Presented by Corr. Member of Academy V. Papunidze, January 30, 2006


ABSTRACT. Bud morphology and shoot-module structure were studi­ed for understanding ecological morphology of 8 evergreen shrubs grown in Ajara, Colchis forests. Of them four species Buxus colchica, Rhododendron ungernii, Rh. ponticum  and Laurocerasus officinalis had scaled buds (50% of total number of species) and all the the rest, e.g. Arbutus andrachne, Daphne pontica, Ilex colchica, Osmanthus decora (50%) had hypsophyllary buds. The types of protective organs were the same for all the trees within each bud type, however, the number of each foliar organ was variable among species. © 2006 Bull. Georg. Natl. Acad.

Peculiarities of Sprout Development in Magnolia Grandiflora

Presented by Corr. Member of the Academy V. Papunidze, March 21, 2006


Abstract. This work shows seasonal rhythms of Magnolia Grandiflora sprouts. The consecutive  phases of sprout and bud developments during the whole year are pointed out, which is of a great importance for the magnolia successful introduction. The boundaries between elemental buds on perennial monopodially growing sprouts of Magnolia Grandiflora may be defined by ring-shaped pits of the scales on the terminal buds, which do not have pits from the leaf plates. The annual growth consists of a singular elemental sprout. During formation of a new sprout conception of primordial leaves on its apex takes place. Increment of the vegetation bud volume during autumn and winter periods is not noted. Conception of flowers in buds on different branches takes place nonsynchronously and it lasts for the same extended period of time as the flowering does.  © 2006 Bull. Georg. Natl. Acad. Sci. pp. 562-564

Key words: Magnolia Grandiflora, plant introduction, seasonal rhythms, evergreen.

Influence of Acidic Precipitations on Green and Red-Leaf Forms of some Vegetables

Presented by Member of the Academy N. Nutsubidze, February 7, 2006


ABSTRACT. Influence of spraying with pH2.5 solution of H2SO4 on leaves of red and green-leaf forms of basil (Ocimum basilicum L.), cabbage (Brassica capitata L.) and beet (Beta vulgaris L.) has been studied. Investigations have revealed that higher physiological and biochemical indices are characteristic for the red-leaf forms of the studied plants, compared with green forms of the same species. In particular, they have more intensive photosynthesis, higher content of total proteins and antioxidants, more activity of auxins. While affecting with acidic precipitations the studied indices appeared to be more stable in red-leaf forms. The obtained results make possible to conclude that red-leaf forms of the studied plants are more adaptive to environmental stress. © 2006 Bull. Georg. Natl. Acad. Sci. pp.565-567

The Modulative Influence of the Mitochondrial Glucose-Specific Lectin  on the Bovine Brain  HCO3-ATPase Activity

Presented May 23, 2006


ABSTRACT. Glucose-specific lectin (BML-Glu) has been isolated from the bovine brain mitochondria. The influence of this lectin on the enzymatic activity of bovine brain HCO3-ATPase of the mitochondrial origin has been studied. It is determined that BML-Glu lectin approximately twice increases the enzymatic activity. The optimal conditions (the concentration of HCO3-ion and of ATP, pH-optimum) of HCO3– ATPase work  in the incubation medium in presence of lectin and without it are determined. It is also determined that the influence of two valence ions on HCO3– ATPase activity changes in the incubation medium in presence of BML-Glu lectin. Namely, due to the influence of BML-Glu-lectin on the enzyme the inhibiting influence of Ca2+ decreases approximately 1.5 times, but that of Cu2+ decreases approximately 5 times. As for Fe2+ and Mn2+ it turned out that in presence of lectin the activating influence of Fe2+ and Mn2+on the enzyme  increases. © 2006 Bull. Georg. Natl. Acad. Sci. pp. 578-581.

Human Sperm Carbohydrate-Binding Proteins (HSp-CBP) at Normozoospermy and Invasion with Chlamidia trachomatis

Presented by Corr. Member of the Academy N. Aleksidze, March 23, 2006


Abstract. Human Sperm Carbohydrate-binding proteins (HSp-CBP) at normozoospermy and invasion with Chlamidia trachomatis have been studied. It is determined that during chlamydeous the lectin activity in sperm plasma increases that of the norm. Mannose-specific lectin (HSp-Man) has been purified on agarose-mannose affinity sorbent with HPLC on Gel-filtrated Ultropac TSK G3000 SW column. Chlamidia trachomatis DNA, causing infection in sperm, has been identified with polymerize-chain reactin (PCR). It has been suggested that mannose-specific lectin could relatively be the immune modulator component of genital tract secret.  © 2006 Bull. Georg. Natl. Acad. Sci. pp.582-585

Effects of Antiepileptic Drugs on Anaphylactic Shock and on Herxheimer Microshock in Guinea Pigs

Presented by the Member of the Academy T. Oniani, February 16, 2006


Abstract. We searched the activity of phenytoine and sodium valproate in  experimental model of anaphylactic shock and in Herxheimer microshock. Guinea pigs were actively sensitized with ovalbumin i.p. and 21 days later the anaphylactic shock or the Herxheimer microshock was performed. Phenytoin sodium or sodium valproate administered orally and also injected 30 min before Herxheimer microshock significantly delayed the development of apnea in the beginning of microshock. Previous inhalation of these drugs did not delay the development of apnea in the beginning of microshock. Therefore i.p. use of antiepileptic drugs modulate apnea during bronchospasm in animals with Herxheimer microshock, and this definitely elucidate mechanisms of clinical efficacy of some antiepileptic drugs in asthma therapy. © 2006 Bull.

Importance of Anti-IL-6 and Anti-HP Antibodies in Case of Gastroduodenal Pathologies

Presented by Member of the Academy F. Todua, February 22, 2006


Abstract. In the recent period the role of Helicobacter Pylor (HP) in inducing gastroduodenal ulcerous processes, gastric adenocarcimoma and extranodal B-cell lymphoma has been determined. In order to identify HP infection bacteriologic, morphologic, radiologic, serologic and molecular-genetic tests are applied. The minimum traumatism and possibility to investigate simultaneously several individuals is the advantage of serologic test (ELISA). Quantitative analysis of interleukin-6 (IL-6) occurred to be most informative among studied parameters. In the course of gastroduodenal processes concentration of IL-6 significantly increases compared to ulcerogenic and mixed processes. It seems, that in case of ulcerogenic processes the production of IL-6 is suppressed. © 2006 Bull. Georg. Natl. Acad. Sci. pp.608-610

Evidence of Influence of Soybean Isoflavones on the Antioxidant Properties of Rats’ Blood and Liver

Presented by Corr. Member of the Academy T. Dekanosidze, July 26, 2005


Abstract. Over the past few years, there has been increasing interest in possible beneficial effects of soybean isoflavones on human metabolism. The aim of this study was to determine the influence of antioxidant properties of soybean on EPR (Electron-Paramagnetic-Resonance) spectroscopic parameters of blood and liver and percentage correlation of hemoglobin derivatives in erythrocytes of experimental rats (Vistar species). After soybean diet of 3 months duration, EPR-signal of ceruloplasmin in the rats’ blood decreased by 25% (p<0.05) compared to control group, the intensity of Fe3+ transferin EPR – signal increased by 20% (p<0.05), the changes of Fe2+ and Mn2+- EPR-signals were not detected.  In liver, EPR-signals of free radicals decreased by 14% (p<0.01) on the background of decreasing of their half-broad signal (by 21%  (p<0.05)). Intensity of EPR signals of FeS complexes decreased by 25.8% (p<0.01), Mn2+- signals – 36.2% (p<0.01), cyt. P-450 – 31 % (p<0.001).  Concentration of oxyhemoglobin rose by 3.2 %, (p<0.005), variations were not revealed in dioxyhemoglobin level, and methemoglobin declined by 3.3% (p<0.01).

The results of the study revealed increasing antioxidant properties of an organism under the influence of soybean diet. We think that increasing consumption of soybean products will prevent an organism from many diseases, which are connected with excess generation of free radicals. © 2006 Bull. Georg. Natl. Acad.

Dualistic Nature of the Georgian National Land Ownership Psychology in Historic and Economic Context

Presented by Corr. Member of the Academy L.Chikava, February 9, 2006


Abstract. In the present paper analysis of dualistic nature of psychology regarding land ownership and its defining factors in Georgia is made. It argues that the principles of individual and communal ownership of land harmoniously combined two distinct psychological tendencies – proclivity to individualism and collectivism. Consequently, on the one hand, they combined economic freedom and private initiative of individualism with the interests of collective, social values on the other hand. © 2006 Bull. Georg. Natl.

The Problem of Personal Choice
(Guram Dochanasvili, “The Best Clothes”)

Presented by Corr. Member of the Academy E. Khintibidze, December 27, 2005


Abstract. In the 70s of the 20th century Georgian literature was greatly influenced by writers who made persistent attempts to break away from the established literary conventions. Guram Dochanashvili‘s (born in 1939) major creation, the novel “The Best Clothes” became the symbol of the world‘s sickness. By the writer the only way to return to God is putting on the Best Clothes (paradigm of Lord‘s Word).

Dochanashvili devotes his great literary talent to pursuit of a life more full, free and intense than the contemporary world can grant to men.

The underlying purpose of his art is to restore natural balance in living destroyed by the evils of atheism. One of the most important aspects of the novel The Best Clothes by Guram Dochanashvili is the problem of personal choice. © 2006 Bull. Georg. Natl. Acad. Sci. pp.627-628

Fall Through Pride in O’Neill’s Drama

Presented by Corr. Member of the Academy E. Khintibidze, January 17, 2006


Abstract. The article deals with some critical questions about the nature of the idea of O’Neill’s plays. O’Neill’s conception of process as the unity in which opposites are reconciled has numberless philosophical parallels  and sources. But O’Neill as a twentieth-century man had to interpret the ancient idea in the twentieth-century symbols and terms. He found this conception in the conditions of modern living and in the language of psychoanalysis. © 2006 Bull. Georg. Natl. Acad. Sci. pp. 632-634
