Enhanced group communications with external participants

A case creation event originating from an external content repository is detected by a processor executing an inbound event handler of a distributed integration framework that integrates a case management system with the external content repository. The case creation event is configured by the distributed integration framework to cause creation of a case within the case management system. The inbound event handler instructs the case management system to create the case within the case management system. An outbound event handler of the distributed integration framework instructs the external content repository to create a proxy case to remotely represent the case created within the case management system.

Case management integration with external content repositories

A micro-mixer and use thereof for synthesis of barium sulfate particles is disclosed. The micro-mixer includes feeding tubes, reservoirs, a mixing channel, a buffer reservoir and a sampling tube. The mixing channel is made of hydrophobic materials and processed into a spiral structure, in which baffles are set in interval arrangement at both sides of the channel wall. The types of the baffles include leaning-forward baffles, vertical baffles and leaning-backward baffles. Setting the baffles helps produce local secondary flow in the mixer, which enhances fluids mixing process. The micro-mixer is suitable to rapid reactions or precipitation processes, whose reaction time is much less than mixing time, and has broad application prospects in many fields involving mixing reaction such as pharmaceutical and chemistry industry.
