With the aid of tensotremorography, a voluntary effort was recorded and characteristics of involuntary and voluntary components of the hands' isometrically recorded efforts were studied. The revealed frequency ranges of the oscillations spectral density's changes corroborate existence of two suprasegmental systems of movements control, the systems being related to voluntary control and a current control of the efforts maintaining or preserving a posture. Results of cross-correlation analysis of the hands' efforts maintained under conditions of a visual feedback are demonstrated in norm and in central disorders of the movement control system. 相似文献

Mathematical methods of experimental design were used to determine the optimal concentrations of nutrient medium components, aeration conditions, and pH providing for the maximum biomass yields, as well as fumarase and aspartase activities, during submerged cultivation of Erwinia sp. The data showed that different concentrations of carbon source (molasses) and pH of the nutrient medium were required to reach the maximum yields of fumarase and aspartase. Calculations suggested that the combination of these optimized factors would result in 3.2-, 3.4-, and 3.8-fold increases in the Erwinia sp. biomass, aspartase activity, and fumarase activity yields, respectively. The experimental data were consistent with these estimates to a 80% accuracy. 相似文献

The survey of the population immunological structure with respect to parenteral hepatitis showed awide circulation of hepatitis B (HB) and hepatitis C (HC) viruses among the adult population of Armenia. During the 5 year period of observation the number of persons having antibodies to HC virus increased 2.7-fold. High occurrence of antibodies to HBsAg of HB virus among the healthy population in 2002 (12.0%) in comparison with 1997 (5.4%) reflected a decreased infection rate with HB virus as well. Antibodies to hepatitis A (HA) virus were isolated, on the average, in 64 % of persons. Simultaneously with a decrease in the proportion of HA cases an increased number of HC patients was registered. No circulation of hepatitis E virus was detected. A high percentage of hepatitis cases of mixed etiology was established, as well as an increased number of combined parenteral hepatitis cases was registered (57.1%). 相似文献

L. acidophilus strain 317/402 "Nariné" shows high antimicrobial activity with respect to pathogenic microorganisms. The degree of the activity of lactobacilli depends on cultivation conditions and the composition of the culture medium and its acidity, age of the culture, conditions of technological process, etc. The antimicrobial inhibition concentration of the product "Nariné", ensuring in vitro activity against Yersinia enterocolitica, Y. pseudotuberculosis, Vibrio NAG, etc., has been established. 相似文献
