A hydrocarbon composition that comprises species of at least 3 different carbon numbers, at least about 95 wt % non-normal hydrocarbons, no greater than 1000 wppm aromatics, no greater than 10 wt % naphthenes, and also has a certain boiling point range; and a process for making the hydrocarbon composition. The panel may be moved from an extended position wherein the control panel is exposed outside the cabinet to a retracted position wherein the control panel is enclosed within the recess. A gray filter disposed in the beam path reduces the intensity fluctuations. The first and the second doped regions may define a channel region of the substrate between them. A level of \u201ctrust\u201d or \u201clegitimacy\u201d about a sender’s communication can be inferred by looking at whether the sender is linked to an intended recipient. The insulation cover is a cap which fits over the top of the substrate, with mold lock depressions contained in the junction between the cap peripheral interior edge and the substrate mating edge surfaces.
