Abstract: A valve train device includes a shaft having one or more actuation contours for actuating at least one actuation element of a valve of a combustion engine, and the actuation contours being arranged on the shaft so as to rotate therewith. A sensor unit including one or more sensors is provided, and each of the one or more sensors has a spatial sensing area for sensing a physical variable. In at least one axial position, an actuation contour of the one or more actuation contours is arranged at least partially in the spatial sensing area of a sensor of the one or more sensors.

Abstract: Mixture compositions made of specifically chosen alkyl carboxylates can be used in a process for the preparation of ester compositions. These mixture compositions and ester compositions can be used in cosmetic applications.

Abstract: The invention relates to a method of cell lysis for forming at least one pore in the cell wall and/or cell membrane of a cell in an aqueous medium for release of at least one intracellular target protein and/or lipid from the cell into the aqueous medium, including subjecting the cell with the intracellular target protein and/or lipid in the aqueous medium to an electrohydraulic comminution; and separating the target protein and/or lipid from the cell. The electrohydraulic comminution is brought about by a pulse current source. The cell in the aqueous medium is subjected to electrical impulse discharges between at least two electrodes of an underwater radio path of a container at a specific operating voltage, impulse energy, and pulse frequency, and at least one pore is formed in the cell wall and/or cell membrane.

Abstract: n-Nonanoic esters of xylitol, sorbitol or erythritol are made, especially for cosmetic or household care compositions, and a process for their preparation is developed.

Abstract: A valve train device includes a shaft, wherein a number of actuation contours for actuating at least one actuation means of a valve of a combustion engine is arranged on the shaft so as to rotate therewith. A sensor unit with a number of sensors is provided, and each sensor of the number of sensors has a spatial sensing area for sensing a physical variable. In at least one axial position, at least one actuation contour of the number of actuation contours is arranged at least in part in the spatial sensing area of at least one sensor of the number of sensors.
