Active Aluminum-Rich Primers

The US Navy has developed and patented active aluminum rich primers that, applied to aluminum surfaces, offer superior protection against galvanic corrosion, are cost competitive with hexavalent chromium and offer comparable salt spray protection, as well as environmental and health advantages.

A High Resolution Piezocone

A new tool has been added to the suite of direct-push applications offered by the Public Works Center (PWC) San Diego and PWC Norfolk. The device, called a “highresolution piezocone” has numerous applications in the environmental and construction fields. The piezocone uses pore pressure measurements to determine water table elevation. It is capable of generating highly resolved hydraulic head values (i.e.

Universal Internal Positive Control for PCR

The US Army seeks to commercialize through licensing a straightforward, effective, universal exogenous internal positive control (UEIPC) for monitoring inhibitors of PCR. This versatile innovation allows for confirmation of negative results as a true negative. It is most suitable for Taqman® based assays. The Joint Program Executive Office of the Department of Defense has chosen this as the solution for its internal positive control.

Well Design Specification (WDS) Software

Researchers at the Naval Facilities Engineering Service Center (NFESC) have developed novel Well Design Specification (WDS) software to be used in fabricating a well for monitoring or remediation of contaminated soil and ground water. Patent No. 6,317,694 (issued November 13, 2004) discloses a method and apparatus for the selection of appropriate filter pack and slot size specifications for each screen depth of candidate wells.

A Patented Method Underlies the Natural Cue Diversion Screen

An optimally performing fish screen does not cause injury or fish mortality; and, it does not interfere with migration or hydraulic efficiency. The U.S. Army Corps of Engineers, Environmental Research and Development Center (ERDC), has invested extensively in the development of a fish behavior modeling capability. An ERDC patent has issued related to a method for determining the probable response of fish in flow fields (patent no. 6,160,759). This method is being implemented in modeling software and has already been utilized at a dam site in the Pacific Northwest.
