[Relaxation of liquid water states with altered stoichiometry].

The integral parameter of the physical state of liquid water, its stoichiometry composition, is considered. This factor takes into account that the substance of liquid water contains oxygen and hydrogen atoms in the proportion other than the ideal 2:1 ratio characteristic of a separate water molecule. The stoichiometry index χ of water--a deviation from the ideal ratio--is shown to be an independent metastable variable that determines equilibrium concentrations of the oxygen-hydrogen molecules.

[Two types of magnetic biological effects: individual and batch effects].

Frequency distributions of the magnetic effects values have been calculated based on the results of about 120 thousand single trials during psychophysical testing of 40 people under normal conditions and exposure to the hundredfold weakened geomagnetic field. Two types of such distributions were shown to be attributed to a) the individual reactions to the change of a magnetic field and b) the batch magnetic effect on the set of the individual reactions. The methodological consequences significant for detecting magnetic biological phenomena and studying their nature are discussed.

[Microwave absorption by magnetic nanoparticles in organisms].

An estimate of the rate of absorption of the electromagnetic microwaves by magnetic nanoparticles in organisms is presented. The absorption takes place due to the energy dissipation at the ferromagnetic resonance. Based on the known solution of the Landau-Lifshitz equation, the imaginary part of the complex magnetic susceptibility is evaluated that gives the absorption rate.

[Influence of the compensation of the geomagnetic field on human cognitive processes].

The influence of the compensation of the geomagnetic field to a level less than 0.4 microT on human cognitive processes has been studied. Forty persons took part in the study; they were divided by sex and age into four groups.

[The paradox of magnetobiology: analysis and prospects for solution].

The wording, content, and corollaries of the so-called "kT problem" are considered. The problem points to the paradox of the biological effects of weak low-frequency magnetic fields. The conventional wording of the problem contains implicit assumptions the analysis of which shows their incomplete physical validity.
