Abstract: A system for determining a crop edge and a self-propelled harvester using the system for automatic control are disclosed. The system comprises a camera that generates optical information of a front environment of the harvester. The system further includes a computing unit that analyzes the images using artificial intelligence so that a planted area of a field on which a plant crop is located may be delimited from a remaining residual area of the field, thereby determining the plant crop. In turn, the computing unit is further configured to determine the crop edge of the plant crop based on the determination of the plant crop and to automatically control the harvester based on the determination of the crop edge.

Abstract: The invention relates to a continuous method for producing a tenside, containing a compound of the formula (1), wherein R2 is a fatty acid alkyl residue and R1 is a linear or branched C1 to C12 hydrocarbon residue, and x is in the range from 1 to 15 by conversion of fatty acid alkyl esters or fatty acid triglycerides having an N-n-alkylized polyhydroxy compound in the presence of an alkali catalyst or a catalyst selected from hydroxides or alcoholates of the 2nd and 4th secondary group of the periodic system at a temperature in the range from 40 to 300° C.
