Abstract: A receiver system using commercially available super high-speed data converters that are able to directly digitize at multiple GHz sampling rates with sufficient accuracy to fit many radio applications. Unlike conventional receivers, no down converters or mixing stages are required. Instead it uses a bank of RF filters from which the desired RF filter, based on the frequency band of interest, is switched in. The frequency spectrum scan rate is very fast as the settling time for the simple RF front-end is small and the speed of RF switching is high. The filtered output is digitized at a multiple GHz sampling rate and all signal processing is done by FPGA or a combination of FPGA and/or a general-purpose processor.

Abstract: Methods, systems, and devices for recording and playing back high speed incoming data using magnetic or solid state storage devices. Incoming data at speeds as high as 10 gb/s are first stripped of their headers and are turned into datagrams. The data stream is then sequentially routed to one of a number of software caches. The data streamed is then stored in a specific software cache and, at the same time, the data is read and transferred to its associated set of storage media. The data stream is then routed to the next software cache. Each software cache has associated with it a set of storage media. To read back the data, each associated set of media sends data to its associated software cache as the software cache sends the data to an outgoing data stream. The data throughput scales up linearly using a plurality of incoming data streams.

Abstract: Pseudomonas strain NRRL B-18086 was isolated as pure culture from the Baton Rouge Sewage Treatment Plant. The strain can utilize chlorinated aromatic compounds as the sole carbon source and will degrade both 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), as well as other xenobiotic compounds.

Abstract: Pseudomonas pseudoalcaligenes strain NRRL B-18087 was isolated as a pure culture from the Baton Rouge sewage treatment plant. The strain can utilize chlorinated aromatic compounds as the sole carbon source and will degrade both 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), as well as other xenobiotic compounds.
