The present invention relates to the use of mixtures containing 2-hydroxyphenylaldehyde and 2-hydroxyphenylketone heterocycloylhydrazone compounds and copper for controlling the growth of fungi and algae. The culture medium enables rapid detection of mycobacterial growth by changing its color. Thereafter, motion or depth data for the given image part of interest is furnished in dependence upon the prioritized set of candidate motion vectors or depth values. Also, an application for copying a directory has to traverse the directory’s structure only one time, because the application does not need to know in advance the total number of files that have to be copied. Communication is established between the first and second communication devices over the communication medium using one of the common communication speeds. Capacitor electrodes, interconnects or other structures may be formed with such a diffusion barrier layer.
