Abstract: Provided is a component arrangement, including a carrier substrate; a spacer which is arranged on the carrier substrate so as to surround an installation space and has an outlet opening on a side facing away from the carrier substrate; an optical component arranged in the installation space; a contact connection which electrically conductively connects the optical component to external contacts arranged outside the installation space; a cover substrate which is arranged on the spacer and with which the outlet opening is covered in a light-permeable manner; and a light-reflecting surface which is formed on an anisotropically etched silicon component and is arranged in the installation space as an inclined surface at an angle of approx.

Abstract: Molecules that are engineered to form an oligomer, wherein each of the molecules comprises an IgG CH2 region with the position 253 by EU numbering substituted to be a cysteine and/or a human ? tailpiece.

Abstract: A control method uses in a membrane filter system operated in iterative filtration cycles, the cycles including a production period and a following flushing. A setting of a crossflow on the entrance side (4) of a membrane (2) in the production period is controlled such that the energy consumption (E) per filtration cycle reaches an optimum. A corresponding membrane filter system is provided.
