Abstract: Disclosed herein are bactericidal compositions that are effective against pathogenic biofilms, especially against biofilms formed by Pseudomonas aeruginosa. The disclosed compositions comprise escapin intermediate products which can reduce the biofilm viability and biofilm matrix of P. aeruginosa.

Abstract: A novel construction of lightweight loudspeaker enclosure wherein the interior is substantially filled with rigid open-celled foam as a structural core. The speaker enclosure is comprised of two basic parts, the structural foam core, and a relatively thin exterior shell. The rigid foam core eliminates acoustic reflections within the interior of the enclosure and prevents flexure or vibration of the exterior shell thereby producing a loudspeaker enclosure of light weight, and high rigidity. Further this construction makes practical the manufacture of very thin or unusually shaped loudspeaker enclosures.

Abstract: Apparatus and method for creating de-identified and linked records is described. More particularly, data records are de-identified at a client computer. De-identification includes field-level encryption. De-identified records may then be sent to a server computer for linkage. Linkage is done using match codes created for such data records at the client computer. The server computer is configured to provide longitudinal linkage of de-identified client records to de-identified master records. In this manner, privacy may be maintained at the client computer prior to transmission of information, and longitudinal linkage of records may occur without exposing personally identifying information. Moreover, method and apparatus for re-identification of longitudinally linked de-identified records is described.

Abstract: Apparatus and method for creating de-identified and linked records is described. More particularly, data records are de-identified at a client computer. De-identification includes field-level one-way encryption. De-identified records may then be sent to a server computer for linkage.

The server computer is configured to provide longitudinal linkage of de-identified client records to de-identified master records.

Abstract: Methods and compositions are disclosed for the microbial degradation of polychlorinated biphenyl compounds (PCBs) at a concentration of 100-200 mg/kg soil in contaminated environments, using natural, non-toxic, environmentally-acceptable compounds for application to such environments, such that PCB-contaminated environments are bioremediated by inducing a metabolic pathway in PCB-degrading microbes. Inoculated or indigenous PCB-degrading microbes, such as Arthrobacter strain B1B are induced to decontaminate the PCBs. Also disclosed are a plant and chemical screening assays for identifying plants that produce metabolites which promote PCB cometabolism. Further disclosed is a method for bioremediating PCB-contaminated environments in a commercially practical manner using l-carvone, a nontoxic and inexpensive chemical component of spearmint, for the in situ cleanup of PCB-contaminated soils, to induce Arthrobacter strain B1B to cometabolize and to substantially degrade PCBs.
