Abstract: A method for carrying out a start-up process of an at least semi-automated vehicle. The method includes: recognizing at least one unsuccessful start-up process using a first set of drive parameters; reporting the unsuccessful start-up process to a control system; receiving changed driving-related boundary conditions from the control system; ascertaining at least one changed drive parameter from the changed driving-related boundary conditions; and repeating the start-up process at least once, using the at least one changed drive parameter.

Abstract: A method for operating an engine of a vehicle, in which after an execution of an automated gear change of a transmission of the vehicle, an acceleration force for accelerating the vehicle is requested when a force value representing a present drive force of the engine is in a tolerance band around a reference value determined before the gear change and a request signal for the acceleration force exists.

Abstract: Provided is a method for producing an alkyl cellulose having a high viscosity and not having an excessively high gel strength. More specifically, there is provided a method for producing an alkyl cellulose comprising the steps of: mixing a cellulose pulp with a first alkali metal hydroxide solution with stirring to obtain alkali cellulose; reacting the alkali cellulose with an alkylating agent to obtain a first reaction mixture; blending a second alkali metal hydroxide solution with the first reaction mixture with stirring, without further blending of the alkylating agent, to obtain a second reaction mixture; and purifying the second reaction mixture to obtain an alkyl cellulose. There is also provided an alkyl cellulose being produced by the above method and having a degree of substitution of alkyl group of 27 to 33% by weight.

Abstract: An X-ray apparatus, having a C-arm X-ray device with at least one electrically operable component that is arranged at a C-arm that is adjustable relative to a holding mechanism, has an arrangement disposed in or at the C-bend or the component and are connected to the component for the transmission of data and/or energy, and another arrangement for the transmission of energy that are disposed in or at a housing connected to the holding mechanism. The exchange of data and/or the transmission of energy between these arrangements ensues in contactless fashion, and the transmission of the data and/or of the energy ensues continuously.
