Some universality in subcritical behavior of real substances and model fluids.

On the basis of the latest advances in Mayer's cluster-based approach, the reduced forms of the well-known virial expansions are derived in terms of scaled reducible and irreducible cluster integrals. This transformation minimizes the dependence on temperature and the effect of parameters specific for each thermodynamic system, thus making the resulting reduced expansions indeed universal on the quantitative level. In particular, the scaling of isotherms and saturation curves for various systems (the Lennard-Jones model, different lattice gases, and real substances with simple nonpolar molecules as well as complex polar ones) confirms the approximate universality of the proposed reduced variables for temperature, pressure, and density at subcritical gaseous states up to the saturation point.

[Features of adaptive responses in right-handers and left-handers, and their relationship to the functional activity of the brain].

In the article there is considered the relationship between adaptation state of the organism and features of bioelectric activity of the brain in right-handers and left-handers. Practically healthy persons of both genders, 23-45 years of age, with the chronic stress disorder were examined. Adaptation status was evaluated with a computer software "Anti-stress", features of bioelectric brain activity were detected by means of spectral and coherent EEG analysis, also the character of motor and sensory asymmetries was determined.

[Determination of phage resistance of E. coli cells with electrooptical analysis of cell suspensions].

Changes in the electrooptical (EO) properties of cell suspensions of the E. coli strains: XL-1, BL-Ril, TG-1, K-12, B-878, and BL-21 (DE) in their contamination with the bacteriophage M13K07 were studied depending on the time of infection. The phage-induced specific changes in the EO parameters of cell suspensions were ascertained to occur only in the E.

[Assessment and correction of psychophysiological features in adolescents at the information science lesions].

The adaptation of teenagers to an educational process in a computer class with the optimum hygienic parameters was studied. The modified procedure "Examinees' emotional assessment of musical tracks" was established to efficiently prevent autonomic dysfunctions and emotional disorders.
