    摘要: A system and method for providing Quality-of-Service (QoS) functions to concurrent event-processing applications in a multi-processing database environment are described. The system includes an Event-Listener interface for determining the QoS functions applicable to the events being processed and an Event-Service interface for invoking the determined QoS functions. The Event-Service interface loads, initializes and activates the QoS functions. The QoS functions are based on service definitions. The Event-Service interface further initializes the service providers and sends the events that need QoS support to the respective service providers for processing. The QoS functions include the services commonly needed in a clustered event-processing database system like Event-Sequencing, Event-Isolation, High-Availability, Event-Filtering and Flow-Control. Other QoS functions might be added to the database system using the same interfaces provided by the invention.

    摘要: A hydraulic fracturing composition includes: a superabsorbent polymer in an expanded state; a plurality of proppant particles disposed in the superabsorbent polymer; a well treatment agent, and a fluid to expand the superabsorbent polymer into the expanded state. A process for treating a well with well treatment agent includes disposing a hydraulic fracturing composition comprising the well treatment agent in a well. The well treatment agent can be a scale inhibitor, tracer, pH buffering agent, or a combination thereof.

    摘要: An oxygen sensor includes a solid polymer electrolyte, e.g., on an acid treated Nafion membrane and uses a diffusion-limited fuel cell type reactions. The sensor avoids electrolyte leakage and avoids consumption of electrodes. In different configurations, a counter or reference electrode can be on the same or the opposite side of the electrolyte as a sensing electrode. An insert limits and controls oxygen diffusion into a sensing chamber containing the sensing electrode that catalyzes reduction of oxygen. Applying appropriate bias voltages to the reference and sensing electrodes causes an output current of the sensing electrode to be proportional to the rate of oxygen consumption based on Frick's law under a diffusion-limited mode. The output current can be measured, e.g., using a resistor to convert the current to a voltage signal.
