The invention relates to a P2P traffic management apparatus and method. The foot assembly comes as part of a kit and is configurable for retrofit attachment to existing desks and workstations. The load header can be disposed on the electrophoresis apparatus. The substrate provides a silicon emitter and a silicon germanium containing base for the bipolar transistor. The seed acts to lower a threshold for SBS in the fiber, thus invoking the nonlinearity. Tooth portions of the resin gear formed in a lower die 12 are pressed in a helical tooth-shaped molding space to deform the tooth portions 4a of the net-shape body 4 into a helical tooth tilted relative to the axial direction, and the direction of reinforcement fibers at the tooth portions 2b of the molded resin gear 1 is tilted relative to the axial direction.
