An electronic fishing information recording and storage device is disclosed. The turbomachine rotor includes a rotor blade with a blade root, a wheel disk with a groove in which the blade root engages such that the rotor blade is maintained in the groove in a positive fit in a radial direction. The mobile units include location tracking technology such as GPS, and wireless communication technology such as digital cellular. The device incorporates a quantum well active layer, a tunnel junction, and control of aperture width using ion implantation. Consequently, the received facsimile document which has been sent from a source to a destination can be managed properly based on the management information. More particularly but not exclusively, it relates to compositions containing thaumatin having particular organoleptic properties, and to processes for their manufacture.
