A wireless-controlled solar brick includes a circuit board disposed with a microcontroller that connects with a signal receiver and a plurality of light sources. The particulate will be at rest in the display receptacle when the motor driven agitator is not operating. Specific embodiments may involve innovative IO cell functions, innovative IC topologies, and innovative IC packaging solutions for single die packages and multiple die packages. The second data symbol stream is processed in accordance with a second spatial processing scheme to obtain a second set of symbol substreams. Said process allows at least a part of the aqueous stream coming from the Fischer-Tropsch reaction to be used as process water in a synthesis gas production plant, subsequently sent to a Fischer-Tropsch plant for the production of hydrocarbons. An interface angle, defined in part between a valve ball and the valve bore in the area of the smallest gap between them, increases as the valve ball is increasingly displaced away from a valve seat of the valve bore.
