Abstract: A process of making a fuel product as an additive from a non-auto-combustible high protein organic material for the destruction of polyfluoro compounds in a thermal process system is provided. Thermal reactions within thermal reaction equipment are controlled by controlling the moisture and oxygen in the reaction atmosphere of the equipment and energy inputs at or downstream of a thermal reaction chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy within the thermal reaction equipment environment are controlled to destroy hazardous polyfluoro compounds.

Abstract: Systems and methods for improving operating room utilization are disclosed herein. Ins some implementations, the method includes retrieving historical statistics of usage rates for an operating room, predicting an estimate of how much time will be unused during a future time block based on the historical information and a planned schedule, and generating a recommendation for the unused time in the estimate. In some implementations, predicting the estimate includes constructing one or more regression models based on the historical statistics. In such implementations, each of the one or more regression models can identify a relationship between the planned usage rate and the actual usage rate based on a different modeling technique. Once the estimate is obtained, the recommendation for the unused time can be based at least partially on an identification of one or more intervals in a future time block that are associated with an open operating room.
