Abstract: A driver assistance system of an agricultural harvesting machine with a harvesting header designed as a draper is disclosed. The driver assistance system comprises a memory for storing data and a computing device for processing the data saved in the memory. The draper comprises a central belt and at least one transverse conveyor belt arranged on the left side and the right side of the central belt for conveying the harvested material to the central belt. The draper forms, together with the driver assistance system, an automatic draper. The computing device operates the automatic draper as a characteristic diagram controller using the saved characteristic diagrams, with the automatic draper optimizing operating parameters of the draper and specifying the optimized operating parameters for the draper. The characteristic diagrams describe the relationship between the operating parameters and quality parameters, and a control characteristic curve is assigned to the particular characteristic diagram.

Abstract: The present invention relates to naphthoquinone derivatives isolated from solid callus cultures from two species of the palaeotropical plant families Dioncophyllaceae and Ancistrocladaceae. It further relates to methods of their production as well as to their use as antiinfective and antitumoral pharmaceuticals.
