Einfluss von Emissionsbelastungen in Waldökosystemen auf die Entwicklung des Feinwurzelsystems von ,ment in the humus layer and a relatively constant length density of fine roots down to a depth of 55 cm. Differences in soil chemical soil properties, especially in the N saturation of the ecosystems, originating from the different pollution levels, were identified as a cause of the different development of fine root systems.

Untersuchungen zum Schadstofftransfer Ausgewählter Organochlorpestizide und Polyzyklischer Aromatiscis effect is due to growth dilution. Increasing concentrations of lindane (γ-HCH) and methoxychlor in soil lead to an increase of their concentrations in maize, whereas benzo(a)pyrene and fluoranthene showed no directly effect.

On the State Reachability Problem for Concurrent Programs Under PowerWe consider the problem of safety verification, formalized as control-state reachability, for concurrent programs running on the Power architecture. Our main result shows that safety verification under Power is undecidable for programs with just two threads.
