An axial tip turbine driven pump in which a first fluid pumped by an inducer is driven by a second fluid that reacts with a turbine blade extending from a shroud on the inducer. Selective potentiation andor inhibition of the 5-HT2A andor 5-HT1A leads to a modulation of serotonergic signal transduction of cells having various receptor subtypes. For purposes of more efficient use of the transmission link, low-volume scheduling information or content are transmitted within designated narrow-bandwidth sub-channels or trickle streams allocated within the broad bandwidth of the transmission channel and such allocation may be dynamic to vary the allocation based upon relative high-volume, high-speed and low-volume, low-speed demands.
