Abstract: The invention relates to a comparison unit (130) configured for determining if a first pH measuring device of a first tank (104; 106) is affected by a pH-measuring problem, the comparison unit being configured for: receiving a first CO2 concentration and a first pH value, the first CO2 concentration being a CO2 concentration of a first gas volume above a medium in a first tank, the first CO2 concentration and the first pH value being measured at a first time when the medium in the first tank is in pH-CO2 equilibrium state with the first gas volume and before said equilibrium state is modified by the metabolism of a cell culture in the first tank, the first pH value being a measured value provided by a first pH measuring device operatively coupled to the first tank (102); receiving a second CO2 concentration and a second pH value, the second CO2 concentration being a CO2 concentration of a second gas volume above a medium in a second tank, the second CO2 concentration and the second pH value being measured

Abstract: A control unit and a method are provided for controlling a riding function of a two-wheeled vehicle. The riding function is configured to guide the two-wheeled vehicle longitudinally and/or transversely in an automated manner. The control unit is configured to detect that the riding function is activated in order to bring about automated longitudinal and/or transverse guidance by the riding function, to determine that dynamic adaptation of the riding function is requested by the driver, and in response thereto, to initiate that, with the riding function being active, a control parameter influencing the dynamics of the riding function is adapted on the basis of the requested dynamic adaptation.

Abstract: Herein is reported a feed mixing device for adding feed solutions with a non-physiologically pH value to a cell cultivation vessel comprising a chamber for mixing the feed solutions prior to their addition to the cell cultivation vessel as well as its use. With the feed mixing device as reported herein feed components can be provided in solution at a pH value at which they have good solubility and/or good stability whereby the pH value can be clearly different from the pH value of the cultivation medium, i.e. different from the physiological pH value. This allows performing the cultivation with more flexibility compared to a cultivation in which the pH value of the feed solution is limited to a small range around the pH value of the cultivation.

Abstract: The invention relates to a motor vehicle lock having an actuating element, in particular a control shaft, which can be adjusted about an actuating element axis, and a drive for adjusting the actuating element, the drive having a rotor which is assigned to the actuating element and which has a permanent magnet arrangement, and a stator with a coil arrangement comprising at least two coils. It is proposed that the stator has at least two poles, via which a magnetic field which is generated by the coil arrangement is guided, and wherein, possibly in a manner which is dependent on the position of the rotor, at least one pole of the stator reaches up to an end side of the rotor apart from an axial gap in relation to the actuating element axis.
