Abstract. In the present paper we consider a class of subsemigroups from BX,
whose every semigroup has as its right unit the quasi-order relation on the set

elements of the semigroup which are contained in the right unit of the given

Abstract. The paper presents the results of investigation of photo-stimulated
diffusion (PSD) processes from continuous source in the GaAs, GaAlAs and GaP
during formation of ohmic contacts, p-n junctions, p+ and n+ areas and insulation
regions. It is shown, that during PSD along with the temperature the role of
the ionization factor is very significant. It is suggested, that in the III-V
compounds the atoms of the III group might be more mobile during pulse-photon
irradiation and probability of vacancy generation in these points might be
higher in comparison with the points of the V group atoms.

Presented
by Corr. Member of the Academy L. Japaridze, march 30, 1998
Abstract. The influence of suspension of the fine-suspended particles into the
acidic manganese sulphate electrolyte solution during electrosynthesis of the manganese
dioxide, on the quality of the product and current efficiency, on the values of
anodic potential and bath voltage, was investigated. It was shown that
suspension of manganese-containing particles, as well as of graphite and inert
materials - glass and corundum, results in considerable increase of titanium
electrode resistance towards passivation: at 2 A/dm2 current density the anodic
potential and the bath voltage retained stable values. The overal picture of incorporation
of the supspended particles into the electrode deposite and their total
expenditure are evaluated. It was found that EMD specimens obtained in such
conditions contain mainly g-MnO2,
which could be utilized in a current sources as a cathode material, unlike e-MnO2 obtained in the same conditions but in the

action of temperature on structural properties of titin has been studied using

tryptophane and tyrosine play a key role in spectra intensity of the intrinsic
fluorescence of titin. It is shown that a rise in temperature from 40°C to 60°C
results in a sharp change of fluorescence intensity and a shift of spectra to
the long wave range. The calorimetry method was used to study thermal
denaturation of titin. The protein under question is not found to have a

The Function of the Tree in the Ritual of Blood
Sacrifice
Presented
by Corr. Member of the Academy R. Gordeziani, April 27, 1999
Abstract. All lives belong to God. It comes from him and to him
it returns, and when he wants it he takes it. But it differs otherwise from
true sacrifice where man makes an offer of his own accord. Since in most
sacrifices men eat the carcass of the victim, what is God supposed to receive?
We hypothesize that burning of the victim was an important and necessary part
in the rituals of blood sacrifice.
