A method for print job partitioning in a printing environment having a plurality of RIP engines includes setting a partition size for a selected print job as a function of one or more of a time sensitive nature of the selected print job and an activity duration measured for the printing environment. Surface scum is exhausted by an overflow arrangement belonging to the first surface chute arrangement and being based on a continuous flow, with which surface scum is overflown in at least two successive phases. The guiding vanes are each mounted within the turbine at their outer diameter by means of rear outer diameter vane hook and are each at their inner diameter in sealing engagement by means of a front inner diameter vane tooth with a honeycomb seal arranged at the corresponding inner diameter part of the outlet of said combustor. 0001 to 5% by weight, based on the oil content of the emulsion to be demulsified. The method includes collecting cells; preparing cells for scanning; scanning of the prepared cells by means of atomic force microscopy; processing of the obtained images through specific algorithms; wherein the algorithms allowing one to identify whether the cell is cancerous or normal. The dust collection module is slidably received within a vacuum cleaner housing and comprises a latch member that can move from a first position, in which it engages with the housing of the vacuum cleaner to retain the dust collection module within the vacuum cleaner, to a second position out of engagement with the vacuum cleaner to allow the dust collection module to be removed.
