An improved cell phone arrangement has a centrally located orientation key, for referencing a location tactilely via the user’s thumb, and the dialing keys arranged in a substantially circular arrangement around the orientation key, in an array having a relatively large diameter but within range of motion of the thumb. The method starts by forming a lipid bilayer inside nanopores of an anodic aluminum oxide substrate, the lipid bilayer containing a membrane protein sample. The method also avoids the use of expensive reagents and capital intensive distillation equipment. The molten composite material may then be extruded through dynamic dies to deliver discrete controlled material that is gravitated onto a lower portion of a mold. The allocation of the areas for disc defect management to the data area enables effective use of the write once disc.
