    Autoregulation of the total number of cells in culture

    Full text link
    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

    Full text link
    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

    Full text link
    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

    Full text link
    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 Colloquium on Group Theoretical Methods in Physics (Dubna 31.07 - 5.08, 2000

    BEC and the particle mass

    Full text link
    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

    Full text link
    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

    Full text link
    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 ZZ^{\prime}

    Full text link
    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 ZZ^{\prime} - 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 ZZ^{\prime} couplings and masses.Comment: 15 page

    The RNO framework to the σ\sigma-particle mass

    Full text link
    The "standard" iso-singlet scalar particle σ\sigma is reconsidered in the reduced normal-ordering (RNO) framework to the effective SU(2) theory. Recent reanalysis of the ππ\pi\pi-phase shift [1] is used.Comment: LaTeX, 6 pages, no figures and table

    New features of two-particle correlations

    Full text link
    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 C2(Q)C_2(Q). 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
