Presented
by Corr. Member of the Academy N.Vakhania,
Abstract. In this paper we consider the currency market where
the foreign savings account process expressed in domestic currency and discount
by domestic savings account represent a martingale with respect to the initial
measure. We find hedging strategies for the European contingent claim to be
optimal in the sense of square criterion.

Absolute and Unconditional Convergence in l1
Presented
Abstract. One of the consequences of the famous
Dvoretzky-Rogers theorem (1950) is the existence of an unconditionally
convergent series in l1 that fails to converge absolutely. The first
direct proof of this fact was given by M. S. Macphail (1947). We give a simple
and elementary example for this kind of series.

The Interaction of Photon Clusters with Matter
Presented
April 5, 1999
Abstract. Analyzing the results obtained with high-power laser
radiation, we revealed that the process of multiquantum absorption of atoms
could be explained by interaction of photon cluster with matter. We expect that
laser radiation consists of multiquantum spikes, the intensity of which is
described by small numbers law. Experimental results are described in the supposition
that multiphoton spikes can be simultaneously absorbed by atoms.

Abstract. Electric power original cost mostly depends on power
system structure, or on the ratio of hydropower output to thermal power output.
With the structural index 0.6 for Georgia the change-over of the thermal power
plant from imported fuel-firing to captively produced fuel would cut down electric
power original cost by 17.1%, whereas the change-over from thermal power plant
to nuclear power plant would make 56% electric power original cost reduction.

Presented
June 15, 1998
Abstract. The investigation of the
influence of rabbit skeletal muscle tropomyosin and rabbit antibodies against
the chicken gizzard muscle tropomyosin on the contractile properties of rabbit
skeletal muscle actomyosin has shown that antigene and antibodies act
identically- they both potentiate contraction, that means that they must have
sites of similar construction.
Considering this fact and literary data about
the antigene sites of rabbit skeletal muscle, chicken breast, cardiac and
gizzard muscles tropomyosins we supposed the localization of domain of
tropomyosin molecule which is responsible over the potentiation of actomyosin
contraction. It corresponds to fragment of tropomyosin molecule which can be
obtained by cleavaging the tropomyosin molecule using the cyanogenbromide -
CNBr-1 and contains the part of tropomyosin molecule from 11 to 126 amino acid
residues inclusively.

Abstract. The mechanism of phenol-peptide conjugates formation has been
studied. Phenol, incubated with low-molecular total fraction in the presence of
enzymatic preparations, forms phenol-peptide conjugates. By the method of
selective inhibition it was found, that the synthesis of the indicated
compounds is accomplished by metalloenzymes with copper and iron active sites.
To localize the process of detoxication the distribution of 1-14C phenol
radioactive carbon in cellular organelles has been studied. It was stated that
intact plastids possess phenol-peptide conjugates forming ability.

peculiarities in early menopause development. For this a complex psychological
study was conducted on 44 women with early menopause aged 30-40 and 35
practically healthy women, of the same age, without menopause. Thus, women with
psychoadaptation disorders are predisposed to early menopause, especially when
they are stressed at this age. We think that it is necessary to study
psychological factors in women with early menopause. The obtained data received
from such a study will help to identify high risk in women and take preventive
