This paper presents the concept of integrated knowledge-based and simulationbased supervisory control for process facilities. Linked to a common SCADA system, such knowledge-based decision procedure, which includes process simulation, assists the operator and facility engineer in operating the facility. The functional chain, which begins with operator knowledge acquisition and moves to knowledg...

Cellulosilyticum sp. strain I15G10I2 was isolated from a coal seam gas water treatment pond at the Spring Gully water treatment facility, Roma, Queensland, Australia. Analysis of the genome of 4,489,861 bp and G+C content of 35.23% revealed that strain I15G10I2 shared limited similarity to members of the genus Cellulosilyticum, family Lachnospiraceae.

For a long time, the only acceptable treatment for a white phosphorous burn was to keep it covered with water until a physician extracted the phosphorous. When the water dried up or ran-off, contact with air caused the burn to re-ignite. This is a serious problem, especially under battle conditions where water may by scarce or non-existent, and the ability to remove the victim quickly to a trea...

This investigation studies desalination powered by wind and solar energy, including a study of a configuration using PVT solar panels. First, a water treatment was developed to estimate the power requirement for brackish groundwater reverse-osmosis (BWRO) desalination. Next, an energy model was designed to (1) size a wind farm based on this power requirement and (2) size a solar farm to preheat...
