Autoregulation of the total number of cells in culture
According to the universally accepted concept of the development of life on
the Earth, multicellular organisms initially emerged as a result of either the
union of identical unicellular organisms with the following functional
differentiation, or the union of symbionts, in which there already was a
certain simple functional separation. However, in either case the progenitors
of multicellular organisms were ensembles, communities of unicellular
organisms. For a certain number of unicellular organisms to be treated as an
ensemble, there must be some interconnection between its members. Colonies of
mechanically connected unicellular organisms were a later, more advanced stage;
here, unicellular organisms living separately are considered. Such
interconnection must, in particular, limit from above the total numbers of the
members of the ensemble, because an excessive increase in these numbers could
disturb the connections between members of the ensemble to the extent of its
destruction. In addition, too large numbers of members in the ensemble could
lead to nutrient depletion in its habitat. One can assume that such
interconnection between unicellular organisms was evolutionarily developed and
genetically fixed. I assumed that modern unicellular organisms retain such an
ability to regulate their total numbers. The validity of this assumption was
tested in experiments, whose results are presented in this paper.Comment: 12 pages, 4 figures, 1 tabl
Treatment of skin deseases in humans by a new method
The original method of treatment of various pathological processes in human
skin covers is described. The method has a brightly expressed differential
action: destroying pathologic cells it does not render any influence on healthy
cells. The examples of application of a method for treatment of some kinds of
skin pathologies are given.Comment: 4 page
On physical nature of radiation regulating quantity of cells in population
It is shown, that spontaneous ultraviolet radiation of cells (infusoria)
plays the role of agent, restricting the upper limit of the quantity of cells
in quasi-stationary phase of cultire's development. The spectral region of this
radiation defined experimentally occurred to be in the range of 200-290 nm. As
the filter cutting off the short wave length part of the spectrum (below 290nm)
1 mm thick plexiglas has been used, while as the filters transmitting short
wave part of the spectrum - 5 mkm thick fluorostatic film or 1 mm thick optical
quartz has been selected. It has been shown, that dynamics of development of
the cells in the culture depends on transparency of nutrient medium to
spontaneous ultraviolet radiation of the cells. Conclusion has been made, that
superweak chemiluminescence of the cells is not a worthless metabolism product,
but plays significant biological role.Comment: 6 pages, 6 figure
Effective Dual Higgs Model with a Dipole-Type Field
The dual Higgs model is reformulated in terms of two-point Wightman functions
with the equations of motion involving higher derivatives. In the system of the
test color charges an analytic expression for the string tension is derived.Comment: 7 pages, latex, no figures, no tables; talk at XXIII International

BEC and the particle mass
We derive new features of Bose-Einstein correlations by means of Quantum
Field Theory at finite temperature, supplemented by operator-field evolution
approach. The origin of the dependence of the measured two-particle correlation
function (as well as the so-called correlation radius) on the particle mass has
received its correct explanation. The lower bound on the particle emitting
source size is estimated.Comment: 11 page
Effective Dual Higgs Mechanism with Confining Forces
We consider the dual Yang-Mills theory which shows some kind of confinement
at large distances. In the static system of the test color charges an analytic
expression for the string tension is derived.Comment: 6 page
Towards the Bose symmetry violation issue
We study the Bose symmetry violation through the decays of heavy vector
bosons at high energies. In particular, the decay of a Z'-boson into two
photons where one of the photons is the vector unparticle in the scale
invariant sector is considered as a sample. We find out that the Bose symmetry
might be violated in the nearly conformal sector at high energy frontier. This
may be useful in phenomenological application to the CERN LHC experiments for
new physics searches.Comment: 9 page
LHC signatures of unparticles in decays of
We investigate the rare radiative decays of extra gauge neutral bosons. In
particular, we established the theoretical predictions for the production of
unparticle in decays of - bosons. The implementation of our
prediction in the analysis at the LHC experiments should be straightforward and
lead to more precise determination or limits of unparticle couplings and/or
couplings and masses.Comment: 15 page
The RNO framework to the -particle mass
The "standard" iso-singlet scalar particle is reconsidered in the
reduced normal-ordering (RNO) framework to the effective SU(2) theory. Recent
reanalysis of the -phase shift [1] is used.Comment: LaTeX, 6 pages, no figures and table
New features of two-particle correlations
We show that a recently proposed derivation of Bose-Einstein correlations
(BEC) by means of thermal Quantum Field Theory, supplemented by operator-field
evolution of Langevin type, allows a deeper understanding of a possible
coherent behaviour of the emitting source and a clear identification of the
origin of the observed shape of the 2-particle BEC function . We
explain the origin of the dependence of the measured correlation radius on the
hadron mass. The lower bound of the particle source size is estimated.Comment: 10 pages, 1 figur
