    Description / Table of Contents: Zusammenfassung Für die Bestimmung des Gesamtenergieumsatzes wurde eine neuartige2H/1H-und18O/16O-Äquilibriereinheit getestet, optimiert und eingesetzt. Es konnte gezeigt werden, daß übergewichtige Frauen und Männer, verglichen mit schlanken Probanden, sowohl erhöhte Ruhe-Nüchternumsätze, als auch erhöhte Gesamtenergieumsätze aufweisen. Der physical activity level (PAL)-Index weist tendenziell eine Verminderung auf, was eine erniedrigte physische Aktivität bei Übergewichtigen vermuten läßt.
    Notes: Summary A new2H/1H and18O/16O equilibration device was tested, standardized and employed for the determination of total energy expenditure. It was shown that overweight men and women have increased resting metabolic rate as well as increased total energy expenditure when compared to their lean counterparts. The physical activity level (PAL)index was slightly decreased which possibly suggests a decreased physical activity in obese people.

    Notes: Abstract The insulating states of three model systems, the two-chain Hubbard model, the two-layer two-dimensional Hubbard model, and the two-dimensional symmetric periodic Anderson model are discussed. All of these systems at half-filling have a charge gap but they can exhibit various types of spin gaps ranging from a vanishing spin gap in systems with strong antiferromagnetic correlations to a spin gap which is equal to the charge gap in the band-insulator regime. The interchain, interplane, or Anderson model f-d hybridization plays a key role in determining the spin-to-charge gap ratio and the nature of the insulating state.
