Abstract: A comminution system for heterogeneous materials includes pumps, a source of liquid in fluid communication with the pumps, a source of heterogeneous material, a mixer to combine the heterogeneous material and the liquid, and nozzles in fluid communication with the pumps, respectively. The pumps are in straight-line alignment with the nozzles. The nozzles receiving the heterogeneous material combined with the liquid direct the combined slurry to an impact zone where the fractions of the heterogeneous material are disassociated.

Abstract: The present disclosure provides methods and systems for regulating communications between a mobile communications device and a plurality of communication servers with improved power consumption at the mobile communications device. Such methods and systems may use a schedule that synchronizes transmission of the communications from the mobile communications device to at least a subset of the plurality of communications servers or (ii) retrieval of the communications from at least the subset of the plurality of communications servers to the mobile communications device over a period of time.
