In addition to an address tag, a coherency state and an LRU position, each cache directory entry includes historical processor access information for the corresponding cache line. Before the final file of the management information is recorded, dummy data of a plurality of successive blocks are recorded at a time by a single operation, and then the final file is additionally recorded after the dummy data. The sub-frame is connected to the main frame at three points. Additionally, the stored object state can be retrieved from a communicatively coupled object cache. The invention also relates to the use of a hydroxyalkylurea of formula in a composition comprising, in a cosmetically acceptable carrier, at least metal oxide-based mineral pigments, for reducing, or even eliminating, the whitening effect on the keratin material after application.
