Certain aspects of this disclosure relate to an isolated protease, and cleaning compositions containing the same. Further, a method for producing such a device is provided. The tracking module is so configured that the second current scaled by the predetermined factor is substantially equal to the second sub-current, thereby avoiding the first sub-current to be reduced by the second sub-current. The optimizer can leverage such information when constructing an optimized query execution plan. A ceramic filter element with support material in the form of particles, with binder material and catalytic material is thus disclosed, whereby the binder material comprises catalytic material, or the binder material is partly replaced by the catalyst material and the support material particles are connected to each other by means of the catalyst andor binder material. A compression spring is provided between a portion of the top side of the cap and the mesh plate.
