The invention combines a subnet bandwidth manager at an access point to track allocations of wireless bandwidth. For a rotating cutterhead, the cutting filament rotates in a rotational direction, aligns itself approximately radially to the rotational axis and defines a cutting circle having a constructively pregiven nominal radius. A lens is positioned proximate to each of the first and second dispersion members, wherein the lens is configured to focus the temporal and spatial dispersions to produce at least one moving spot of light. A cationic microfibrillated plant fiber that is cationically modified with a quaternary-ammonium-group-containing compound, and that has an average diameter of 4 to 200 nm. The Supercritical carbon dioxide may include an ionic liquid in one embodiment.
