The invention relates to fullerene compounds of the following formula: in which X1, X2, X3, X4, X5, Y1, Y2, V, W, F, E, R, r, n, p, and q are defined as in the specification. A sprite sheet comprising a plurality of sprites is created, using the data defining the avatar. Using the scene complexity map, a content player may download scenes of lower scene complexity levels from video streams encoded to lower bit rates to manage the bandwidth consumed to download the video content and allow for the downloading of scenes of higher complexity levels from video streams encoded to higher bit rates. The clamp apparatus contains a sensing mechanism that discerns the responses of the conduit body to the change in line pressure from below to above atmospheric pressure. A request is received for a voice application based upon a user requesting a telephony service.
