A method and system selects between a LED light source and an electroflorescent light source, such as a CCFL light source, to illuminate a LCD panel that displays information generated by an information handling system. In an embodiment of the invention there is provided a hetero-multivalent binding agent with affinity for a member of the TGF-\u03b2 superfamily. The multi-taper jig is then oscillatory moved in a direction perpendicular to a longitudinal length of the ceramic mold body while heating the partition walls forming the cells, so that the opening of one cell is closed and sealed completely and the opening of the adjacent cell is enlarged in area. At least six rods are used to maintain this alignment. If it is determined that the Used field of the binding entry is equal to a predetermined value, the correspondent node sends a reauthentication command message to the mobile node.
