The American Put Option in a One-Dimensional Diffusion Model
Presented by Member of the Academy E. Nadaraya, June 28, 2005
ABSTRACT. A new result is obtained on the vanishing of the local time of a nonnegative semimartingale. Based on this result, a representation of a value function of the American put option is obtained in a one-dimensional general diffusion model. Using this representation, the existence and continuity of a partial derivative of a value function with respect to x is proved, which automatically yields the well known smooth fit condition. © 2005 Bull.

Influence of Laumontite Containing Rocks Applied into the Soil on the Raise of Wheat Crop Yield
Presented by Member of the Academy T. Andronikashvili, June 4, 2005
ABSTRACT. According to the experimental results, it has been shown that the introduction of natural zeolites laumontite containing rocks into the soil reduces the weed growth and positively affects the wheat crop yield.

Analysis of Pharmacokinetics of Haloperidole by
Presented by Member of the Academy T. Dekanosidze, July 6, 2005
Abstract. Under conditions of chronic experiment (12 sexually mature dogs were treated by 0.5% 1 ml of haloperidole during 10 days) simultaneous analyses of invariable form of the preparation, its metabolits in blood plasm, and of supernatante washed from the surface of erythrocytes were carried out. It is shown, that maximum concentration (Cmax) of unchanged form of haloperidole exists in supranatant washed from the surface of erythrocytes 30 minutes earlier, than in blood plasm.
In the a-phase and b-phase of elimination process of haloperidole, its invariable form, bound with protein
fractions of supernatant, gradually moves from supernatant to the plasms, and its oxidized form is less mobile than
invariable form. © 2005 Bull. Georg. Acad. Sci.

Severe Persistent Bronchial Asthma: High Efficacy of Carbamazepine
Presented by the Member of the Academy T. Oniani, July 12, 2005
Abstract. A 7-yr-old male patient had severe persistent bronchial asthma last 3 years. Therapy by beta-agonists and inhaled hormones caused unstable and non-complete short-term remissions. Every spring and autumn our patient had severe exacerbations, and i.v. injections of prednisolone were necessary to suppress severe asthmatic attacks, with following continuation of peroral indication of hormones.
After receiving of carbamasepine asthmatic attacks completely disappeared. For three years patient received only carbamasepine as antiasthmatic medicine. Now he is 11 yr-old, and he does not receive any medication and has no asthma he is practically healthy person. This case supports our earlier published data concerning high antiasthmatic efficacy of monotherapy by some antiepileptic agents. © 2005 Bull. Georg. Acad. Sci.

Dynamic Helical Biphasic CT in the Detection of Intrahepatic Arterioportal Shunts
Presented May 17, 2005
ABSTRACT. The increased use of dynamic helical biphasic CT of the liver has demonstrated the frequent occurrence of arterioportal shunts (APS) within both the cirrhotic and non-cirrhotic liver. Recognition of APS can suggest the presence of previously unsuspected disorder and false-positive diagnosis (hypervascular tumors) or overestimation of the size of liver tumors (e.g. hepatocellular carcinoma) can be avoided. From our experience, the helical CT findings of APS are as follows: early and marked enhancement of the main portal vein, segmental branches, or major tributaries with an attenuation approaching that of the aorta without enhancement of the superior and mesenteric and splenic veins; and the transient, peripheral, wedge-shaped hepatic parenchymal enhancement during the HAP. © 2005 Bull.

Presented by Member of the Academy D. Muskhelishvili, October 11, 2005
ABSTRACT. Research of Georgian political emigration and different issues reflected in the literature of emigrants is extremely significant for the Georgian historical science. It will contribute to the correction of those gross "mistakes" which had been made by the so-called "Soviet historiography" during 70 years of the soviet domination. The objective of the present work is to fill the existed gap. We have studied how the issues of the history of Georgia and the Caucasus of the XVIII-XX centuries were presented in the Georgian emigrant literature. © 2005 Bull. Georg. Acad. Sci.

Freedom of Choice as Mythological Archetype
Presented by Corr. Member of the Academy R.Gordeziani, June 28, 2005
ABSTRACT. The article deals with one of the central archetypes of literature - the problem of freedom of choice. Symbolically this archetype is represented as two triangles: the triangle of evolution and involution, together composing a hexagon. As example of reflection in literature of the triangle of involution convergence into the matter is used a myth about Narcissus. The reflection of the triangle of evolution ascending to the good and spiritual origin is traced on the examples of tales by T.Mann "Law", R.Bach "Jonathan Livingston Seagull", Herman Hesse "Sidhartha", and Paolo Coelho "The Alchemist". The destructive effect of incapacity to make the right choice or prevention of other people to follow their chosen way of life is studied on the example of the tales by Thomas Mann "Exchange Heads", "The Deceived", "Mario and Magician" and S.Maugham novel "Magician". © 2005 Bull.
