 Title    Zur Kenntnis farbiger ternärer und quaternärer Zintl-Phasen Coloured Ternary and Quaternary Zintl-Phases  
 Abstract    Ternary and quaternary, mostly coloured compounds of Au, Pd and Pt, resp., with Li, Mg, Sc and Sn were prepared and structurally investigated. They crystallize in a "filled" Zinkblende type structure (space group F?3m) and can be characterized as ternary or quaternary Zintl-phases. Colours seem to depend on unfilled d-orbitals of Au, Pd or Pt.

 Title    Influence of Lithium Ions on Human Circadian Rhythms  
 Abstract    Lithium carbonate lengthens the circadian period in humans under temporal isolation (arctic summer four groups. L i+ ions are known to change the period length of several circadian rhythm s in plants and animals [1], In all cases reported so far the effect is a lengthening o f the free running period. An experiment has been performed on a single person in an isolation unit to test whether L i+ acts on hum an circadian rhythms and the results provided have not been conclusive [2]. We have conducted an experiment to determine the influence o f L i+ on the hum an circadian system under arctic sum m er conditions. The continuous light and abscence o f other 24 h tim e cues allows free run o f hum an circadian rhythms [3]. In this brief report, we present some salient results of the effects of Li+ on the tem perature-, sleep-wakefulness-, and activity rhythm in some humans. More details of this investigation will be published elsewhere.
