[Muscle activity and heart rate during rhythmical work on the hand ergometer. I. Heart rate, bioelectric muscle activity and mechanogram relative to the strength of contraction].

The experiments were carried out on 11 subjects ranging in the age from 23 to 37 years. Heart rate, integrated electrical activity from 4 muscles of the forearm and the hand and mechanical activity were measured simultaneously during rhythmical work using a hand-ergometer. The strength of the dynamic contractions was 20, 40, 60, 80 and 100% of a maximal voluntary contraction.

[Repeated characterization, analysis of variance limitation and discrimination analysis classification of EEG-activity patterns in human sleep].

1. To describe quantitatively and to deliminate nine EEG sleep patterns, mean values and standard deviations of abundances of the frequencies 0.8 .

Primary structure of protein L10 from the large subunit of Escherichia coli ribosomes.

The complete primary structure of protein L10 from the large subunit of the Escherichia coli ribosome has been determined. L10 is composed of 165 residues and has the amino acid composition: Asp6, Asn3, Thr9, Ser6, Glu14, Gln4, Pro5, Gly9, Ala33, Val15, Met5, Ile5, Leu15, Tyr3, Phe6, His1, Lys12, Arg13 and Cys1. The molecular weight of L10 is 17 738.

[Analysis of variance delimitation of factors influencing studies of acoustic evoked potentials].

The effect of the variables "stimulus intensity", "residual effect of previous stimulus intensity", "period effect" and "subject effect" on the amplitudes and on the peak latencies of the N1 and P1 components of the acoustical EEG evoked potentials was studied in human subjects with the use of an orthogonal experimental design. The stimulus intensity (30, 50 and 80 dB) accounts for the greatest part of the total variance of the amplitudes and of the peak latencies of N1.-The existence of a totalvariance component due to differences between the subjects is also statistically significant (P equals 5%), As far as the period effect (habituation effect) is concerned, only its effect on the amplitude of N1 - P2 is statistically significant.

[Variance and discriminatory analyses for the classification of wakefulness-dependent EEG patterns].

1. To describe 8 alertness-dependent EEG activity patterns to be observed during wakefulness with eyes closed, mean values and standard deviations of the frequencies 4, ..

[Interindividual variability and intraindividual reaction stability of bioelectric muscular tension of the long finger flexor in model exercise].

Twelve untrained subjects had to perform opening and closing movements of the hand (2 mm-sec(-1) on a hand ergometer. The load was 2kp for woman and 5 kp for man. Two sequences of the test were carried out, one after the other.
