RESUMO

Experimental results of the study on causes of the difference in thermal conductivity coefficient of water under water heating by a biological object (operator hand) compared to heating by an electric radiator of the same temperature are given. Two possible causes of the observed effect, which are associated with the difference in the spectral composition of radiation generated by the operator hand compared to an electrical source of heat and solubility in water of CO2 released from human skin, are discussed.

RESUMO

The dynamics of string growth was studied in model homochiral solutions of biomimetics, trifluoroacetylated amino alcohols (TFAAA) in heptane, water, and inverted heptane-water emulsion. In heptane and water, a thick (~1 µ in diameter) string had a crown of thin strings on its growing terminal and these thin strings effectively adsorbed dissolved TFAAA. In emulsion, the strings grew inside the water droplets, in which this TFAAA cannot be solved, presumably due to transport of TFAAA molecules from heptane into water in the surface layer surrounding the string. Applications of these phenomena to in vivo cell commutation were discussed.

RESUMO

A phenomenon of superspiralization was revealed in homochiral solutions of biomimetics with strings lengths from 10(2) nm to 10(2) µ and longer: strings of greater size spontaneously formed in solution are twined of the smaller strings, which also have a helical structure. The chiral pitch depends on the conditions of formation of a particular string and can vary by several times in different strings of the same specimen.

RESUMO

The temperature dependence of conductivity of water heated by a biological object, as well as electrical, aqueous and other types of heaters was studied. Substantial differences in the conductivity parameters of water heated by bioobjects and physical sources of heat were found. The effect of "memory" of water in response to the biological influence and differences in the entropy of water upon biological treatment and upon heating by physical sources of heat were revealed.

RESUMO

A correlation between the solar activity (Wolf numbers) and electric conductivity of water was found. It was suggested that changes in the electric conductivity of water are the primary cause of the known correlations between the solar activity and various processes in the biosphere.
