Das Werk beschreibt erstmalig in einer geschlossenen shape eine Simulationsmethode zur schnellen Berechnung von Kontakteigenschaften und Reibung zwischen rauen Oberflächen. Im Unterschied zu bestehenden Simulationsverfahren basiert die Methode der Dimensionsreduktion (MDR) auf einer exakten Abbildung verschiedener Klassen von dreidimensionalen Kontaktproblemen auf Kontakte mit eindimensionalen Bettungen.

7. , 1996; Schulz, 1998). In some families, such as moths of the family Arctiidae, the larvae feed on PA-containing plants. In other families, such as Nymphalid butterflies of the sub-families Danainae and lthomiinae, the larvae of most species live on other plants, but the adult males seek out PA-containing plants and ingest alkaloids from wilting, dead, or damaged plant material or from nectar. , 1994) and, in some species, are also converted into pheromones and other signalling chemicals involved in mating.

Mattocks and Bird studied the rates of fonnation of N-oxides and pyrrolic metabolites in vitro (Mattocks & Bird, 1983). The relative production of pyrrolic metabolites to N-oxides was dependent on the structure of the esterified acid (Mattocks, 1970), and was the highest for close-chain macrocyclic diesters and the lowest for open-chain diester alkaloids. These differences were accounted for by the steric hindrance (at position Cg of the necine) offered by the acid moiety at the site of each respective reaction.
