We present a new linearization method for high-power amplifiers, using an envelope predistorter (EPD) including envelope delay taps and control circuits, for memory effect compensation. The lower and upper third-order intermodulation (IM3) components

The high cost of surfactant enhanced aquifer remediation (SEAR) could be reduced if contaminants in the extracted surfactant flushing water could be biodegraded, and the surfactant reinjected. To test this concept, ex situ biotreatment using immobili

Column studies were conducted to assess the suitability of a non-ionic surfactant Tergitol NP-10 (TNP10) for washing pentachlorophenol (PCP) from soil and non-aqueous phase liquids (NAPLs). Flushing of 50 and 200 pore volumes of 5 g/L TNP10 was requi

We describe a RF predistorter (RFPD) which has multiple intermodulation (IM) paths for individual cancellation of IM3 and IM5 components. To compensate for the memory effect of the power amplifier and improve the linearization ability of the predisto

Non-ionic surfactant addition was investigated as a method to remediate pentachlorophenol (PCP) contaminated soil. The goal was to quantify surfactant (Tergitol NP-10 (TNP10)) and PCP sorption to soil and their interactive effects under varying pH, i

The partitioning of the non-ionic surfactant Tergitol NP-10 (TNP10) and pentachlorophenol (PCP) into a mineral oil light non-aqueous phase liquid (NAPL) were quantified in batch tests. Due to the ionizable nature of PCP, the effects of pH and ionic s

A tuberculous pleural effusion may be a sequel to a primary infection or represent the reactivation of pulmonary tuberculosis. It is believed to result from a rupture of a subp leural caseous focus in the lung into the pleural space. It appears that
