摘要： A permeable barrier for decontaminating groundwater having two distinct components for increasing contaminant removal. Preferably, the barrier material is a mixture or distinct layers of bone-char phosphate material and iron oxide pellets. The barrier material can be incorporated as part of a shallow trenching decontamination system, or incorporated in a non-pumping well, or array of non-pumping wells, as part of a deep underground decontamination system. The system can be used for removing, among other things, a radionuclide, such as uranium, from water.

摘要： An electronic turbocharger control system for an internal combustion engine is provided to control at least one turbocharger by controlling a bypass valve and a wastegate in response to the engine speed, engine load, ambient temperature, and the operating environment's barometric pressure wherein the turbocharger is controlled to operate within predetermined islands of efficiency on a pressure ratio versus mass airflow map thereby allowing the adaptation of one turbocharger assembly for various applications. The method and apparatus provides improved engine efficiency and increases low speed torque.
