    The influence of day and night work on the circadian variations of cardiovascular performance (1982)
    Springer
    European journal of applied physiology 48 (1982), S. 11-23

    Thema: Medizin
    Notizen: Summary Circadian variations of the pre-ejection period, Q-T interval, heart rate and oral temperature at rest and in day and night shift work were investigated. At rest, pronounced circadian variation was found in heart rate, pre-ejection period and Q-T interval. The ratio between Q-T interval and heart rate also shows a distinct circadian variation. When working, the rest rhythms of the variables were obscured. The physiological implications for shift work are discussed.

    Parameterization of the hyperfine structure of metastable states in103Rh (1989)
    Springer
    The European physical journal 14 (1989), S. 139-142 
    Details
    ISSN: 1434-6079
    Schlagwort(e): 35.10.F ; 31.30.G
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract The experimental data on the hyperfine structure of metastable even parity states in103Rh have been analysed by means of an effective-operator formalism. The effective radial parameters of the magnetic dipole interaction are determined, using wave functions in intermediate coupling. The comparison with relativistic calculations gives an estimate of the effects due to configuration interaction.

    Reactivity of small transition metal clusters (1993)
    Springer
    The European physical journal 26 (1993), S. 334-336 
    Details
    ISSN: 1434-6079
    Schlagwort(e): 36.40+d
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract A new experiment for measuring the reactivity of neutral metal clusters is presented. A low pressure reaction cell is used to measure the sticking ofO 2 andD 2 gas on small transition metal clusters ofCu, Fe, Co andNi. The experiment yields absolute values for the sticking, at a controlled number of cluster/gas collisions, facilitating comparison with theoretical calculations and other experiments. The most striking result of these preliminary measurements is the difference between oxygen sticking onCo N and onCu N , with the sticking onCu N showing a clear correlation to the electronic shell model, while the sticking onCo N only exhibits a sharp increase with size, reaching sticking probability=1.0 forN〉25.
