Abstract: A bone cement mixer includes one mixing space (5) for mixing powder and liquid components (2, 4) to make bone cement. The powder component (2) is placed in the mixing space (5) and the liquid component (4) in a liquid container (3). The liquid container (3) may be an aerosol container (15) and contains, in addition to the liquid component (4), a propellant gas for pushing the liquid component (4) out from the aerosol container (15) into the mixing space (5). The aerosol container (15) has a connecting element (16) for connecting it to the bone cement mixer (1), and it is closed and adapted to being opened when it is connected to a corresponding connecting element (17) on the bone cement mixer (1), so that the liquid component (4) is pushed out from the aerosol container (15) into the mixing space (5) by the propellant gas.

Abstract: Systems and methods are described for performing image analysis. A computer-implemented method for analyzing images may include quantitatively analyzing image data to identify image objects relative to a background portion of the image according to predefined object criteria, the image data including a plurality of image objects that represent objects in a sample distributed across a substrate. The identified image objects are further clustered into groups or colonies of the identified image objects according to predetermined clustering criteria.

Abstract: A device for abrasive-blasting of workpieces including a chamber (which is to be evacuated during operation) having a first opening, a nozzle pipe unit with a nozzle pipe which can be inserted through the first opening into the chamber, and a container for the accommodation of blasting material, in which case the container for the accommodation of blasting material is mounted, or can be mounted, to the nozzle pipe unit in such a manner that the blasting material can flow freely out of the container into an inlet of the nozzle pipe unit.
