ABSTRACT

A mathematical model of the air diffusion process through the water surface, taking into account the reverse flow of bubbles was proposed. The numerical solving gives self-oscillation of the dissolved air concentration. Spectral density of these oscillations has the 1/f-noise form, which explains the fluctuating nature of the observed properties of water and biological effects, which depend on the amount of dissolved air. A mechanism of spontaneous water luminescence observed after laser irradiation was suggested. The calculated luminescence self-oscillations have the form of a fractal with an infinite sequence of periods, which evolve in time and that is qualitatively consistent with the experiment.

ABSTRACT

The physical validity of the mechanism proposed by the author is discussed. According to the theory a prolonged exposure to weak electromagnetic fields leads to an enlargement of the micro-bubbles and degassing of bioliquid. Degassing alters the physical and chemical properties of bioliquid that affect some medical and biological indicators. The following changes in some blood parameters during degassing in vitro were analyzed: a decrease in the glucose concentration, an abnormal activation of blood clotting, an increase in the rate of blood cell aggregation, a decrease in the effectiveness of aspirin as an inhibitor of platelet aggregation and the slowing of indirect anticoagulants. All of this evidences a possible correlation between the increasing electromagnetic pollution and the risk of cardiovascular disease.

ABSTRACT

The mechanism underlying the excitation of the hydrogen bond with ATP hydrolysis was considered. Coulomb interactions of the proton of the hydrogen bond A-H...B with the electrical field of the covalent bond of ADP-P were calculated. It was shown that the electrical field of the covalent bond of ADP-P excites oscillations of the proton in the complex with the hydrogen bond A-H...B and displaces it from the equilibrium towards the covalent bond. The distortion of the potential curve depends on a change in the length of the covalent bond of ADP-P. Adiabatic potentials U0 and UN of the ADP-P system were calculated, which correspond to the ground and excited states of the H-bond proton. It was found that as the length of the bond of ADP-P (rho) increases, the branches of the adiabatic potential U0(rho) and UN(rho) intersect. At the intersection point, the system can transit to the branch UN(rho), which can lead to a reduction of the barrier and a break of the covalent bond of ADP-P. Presumably, this mechanism is universal for processes of transformation of the chemical energy of ATP to the energy of excited hydrogen bond, a mechanism for the maintenance of heat balance and reduction of entropy in a living organism.
