An apparatus for treating pollutants in a gas may include a source of hydrogen peroxide, and a treatment injector for creating and injecting dissociated hydrogen peroxide into the flow of gas. The data packet characteristics can include transport protocol number, source and destination port numbers, source and destination IP addresses, for example. In another embodiment, second phase air flow may be deflected by a configuration of air deflectors to create a low pressure over a flow tube to enhance power generation. The luminescent material is distributed across the remote phosphor layer andor the scattering structures andor scattering material are distributed across the scattering layer for compensating at least partially the difference in light emission characteristic of the at least one light source. A control assembly independently controls the drive elements, so that fuel flow to each nozzle group is independently controllable. A retaining bolt is extendable through the coupling element adjacent the shaft receiving slot and to be received and retained in a bolt receiving recess in the upper shaft surface adjacent the forward shaft end after the shaft forward end is inserted in the coupling element slot.
