    Description / Table of Contents: Zusammenfassung Vorgestellt wird eine schnelle Nachweismethode für 4-Hydroxicumarine aus Organen oder Blutproben. Bei Verwendung eines Ultraschallhomogenisators ist die Analyse nach spätestens 30 min abgeschlossen. Die Identifizierung der Cumarinderivate erfolgt durch Derivativ-UV-Spektroskopie im Normalspektrum und dessen 1. Ableitung bei 340–240 nm. Als weiteres Nachweisverfahren kann zusätzlich die HPTLC angewendet werden.
    Notes: Summary Presented here is a rapid method of identifying 4-hydroxycoumarins in organs or blood samples. Using an ultrasonic homogenizer, a complete analysis is obtained in less than 30 min. Coumarin derivatives are identified by means of derivative UV spectroscopy in the normal spectrum and its first derivation at 340 to 240 nm. HPTLC can be employed as supplementary identification method.

    Notes: Abstract There have been only few attempts to extend fuzzy logic to automated theorem proving. In particular, the applicability of the resolution principle to fuzzy logic has been little examined. The approaches that have been suggested in the literature, however, have made some semantic assumptions which resulted in limitations and inflexibilities of the inference mechanism. In this paper we present a new approach to fuzzy logic and reasoning under uncertainty using the resolution principle based on a new operator, the fuzzy operator. We present the fuzzy resolution principle for this logic and show its completeness as an inference rule.
