A pseudo-image is produced by combining deep-reading azimuthally sensitive resistivity measurements with azimuthally insensitive resistivity measurements made by a multiple propagation resistivity tool. The light-emitting element emits light L1 having a wavelength range within the visible region. The peroxide has an activity ranging from about 40% to about 100%. The shorthand connection identifier field can be sized to support a predetermined number of mobile stations. The flow control between the ULP and the IPSOE is credit based.
