The invention relates to a method and device for dissolving solid bodies with a liquid, in particular for bringing solid bodies of different shapes and sizes, but mainly very course bodies, in contact with liquids, in order to dissolve them by a chemical reaction or dispersion. Light emitted by the sheet is detected with a line sensor constituted such that a reciprocal of an array pitch of photoelectric conversion devices is larger than a value two times as large as a spatial frequency of stripe-like grid patterns recorded due to the stationary grid, which spatial frequency is taken with respect to an array direction of the photoelectric conversion devices. By controlling the types and addition amount of the alkaline earth metal oxide, the linear shrinkage behavior can be considerably controlled while maintaining the electrical property unchanged. The network subsystems form relay networks that wirelessly carry telemetry and control data without the need to penetrate the earth. Embodiments also include the runtime optimizer retrieving from a remote address cache associated with the second task, a second SVD address indicating a location within a memory partition associated with the first SVD, in response to receiving the broadcast reduction operation header.
