Abstract: A device for the cleaning of pipes, such as household waste and sewer pipes is proposed, the device includes a nozzle movable in at least three axes within a pipe for providing a jet of cleaning fluid directed to soilage in pipes; a cleaning hose for supply of cleaning fluid is connected to the nozzle and a swivel mechanism for deflecting the nozzle at an angle relative to a longitudinal axis, a front end portion of the hose is bent in a bending direction in a bending plane; at least one drive for deflecting the nozzle around the longitudinal axis by changing the direction of bending and the bending plane without torsion to the cleaning hose.

Abstract: The invention relates to the non-covalent, self-organizing hydrogel matrix for biotechnological applications containing a covalent polymer peptide conjugate, wherein the covalent polymer peptide conjugate comprises conjugates of two or more peptides that are coupled to a polymer chain and the peptide sequence contains a recurring dipeptide motif (BA)n wherein B is an amino acid having positively charged side chain, A is alanine and n is an integer between 4 and 20.
