Abstract: The present invention relates to a skin care system (10), comprising: (i) a skin treatment device (12) for treating a skin of a user; (ii) a receiving unit (14) for receiving information on the skin of the user; and (iii) an evaluation unit (16) which is configured to evaluate the received information on the skin of the user and to determine based on said evaluation one or more personalized device settings for operating the skin treatment device (12). The skin treatment device (12) comprises a control unit (36) which is configured to operate the skin treatment device (12) upon initiation based on the determined one or more personalized device settings.

Abstract: A slide bearing for a centrifugal pump in which the slide bearing is lubricated by the pumped medium and is composed of a stationary part disposed in the housing of the centrifugal pump and a rotatable part which is supported by the shaft of the centrifugal pump and interacts with the stationary part to give a sliding pair. One part of the sliding pair is composed of a composite material, especially carbon fibers or silicon carbide fibers in a matrix of PEEK, carbon or carbon combined with silicon carbide. The other part of the sliding pair has a sliding surface made of a hard metal material and supported by a support material. A bond produced in the molten state is formed between the hard metal material of the sliding surface and the support material which supports the sliding surface of the other part of the slide bearing. The resulting slide bearing can be used in chloride-containing and/or corrosive media and has a sliding surface that is not prone to undercutting corrosion.
