A method of forming an electrical isolation trench in a silicon-on-insulator structure. An elastically deformable sleeve is arranged on an end of the nozzle outlet side and defines a gap width which can be varied by axial setting movements of the mandrel andor the nozzle body. The method includes, in response to the monitoring indicating first data on the computing device is modified by the application, synchronizing, by the computing device under control at least in part of the data library service, second data stored on one or more storage providers in a network with the first data modified by the application and stored on the computing device.
