A plant extraction assembly includes a housing that may be worn on a user’s back. The tunnel element may have a first opening at an outer surface side of the shell and a second opening at an inner surface side of the shell so that air flow may occur between the openings and wherein the tunnel element is fused to the outer shell. The hyperbranched polymer has, as a branched structure, a repeating unit structure produced from two dithiocarbamate compounds each having a vinyl structure, at the polymerization initiation site having a vinyl structure. In response, the user may select a report topic and, thereafter, the appropriate available report may be directly presented or displayed to the user without any further user interaction. A central processing unit of the computer system is configured to use the memory bus to store data in the memory module.
