An embodiment configured according to principles of the invention includes a plate defining a hexagon having a base parallel with joint between concrete slabs. The inducer is a carbohydrate constituted of a carbohydrate linked in the \u03b2-position to glucose, or a carbohydrate with a \u03b2glucoside subunit, preferably selected from cellobiose, cellulose, starch, cellotriose, and trehalose. The unfinished electrode is treated by exposure to a chemical etchant for a time sufficient to form a finished electrode characterized by a smooth nose and shank surface and rounded undercut and ends. In more detail, the first message 206 is sent through a cellular network radio 208 of the container unit 201. The intercoupling component comprises: an insulative support member; a plurality of electrically conductive terminal elements; a second insulative support member; and a seal member positioned between the first insulative support member and the second insulative member to restrict fluid flow along the terminal elements.
