This Phase II project addresses the development of technology that would provide field-based quantitative detection of a wide range of environmental contaminants through the use of molecularly imprinted polymers and fluorescence detection. The proposed method would complement immunological methods of analysis that have been adapted to contaminants such as herbicides and pesticides. The well-docume ...

There is an immediate need for rapid, portable analytical instruments to ensure the safety of natural and manmade water supplies, including source, recreational, treated, and distributed waters. Echo Technologies, Inc., proposes a Phase I project to develop and demonstrate a new type of optical biosensor that is simple, rapid, specific, and sensitive. The biosensors are based on the use of fluores ...

The magnetic field distribution in a Z-pinch, can be used to infer the currentsflowing in the pinch and study the stability during the implosion phase. Faradayrotation techniques are too insensitive for measurements during the run-in phase.Similarly, it is difficult to infer the Zeeman splitting from spectrally resolvedline profile when the splitting is much less than the absorption line width d.H ...

Drilling has been an integral part of defense community weapons effects testing for over 40 years. Hard target defeat programs have required specialized drilling technology in the creation of test targets and in the monitoring of weapons tests, that canonly be accomplished by directional drilling. Unfortunately the cost of conducting directional drilling, the typical use of large volumes of wate ...

The use of enzyme-linked immunosorbent assay (ELISA) to detect contaminants such as solvents, fuels, and pesticides in soil and water samples is now well established. Although ELISA and related methods can facilitate analysis of samples, several washing and separation steps are involved that require 30 to 120 minutes per sample to reach equilibrium. Recently, near infrared fluorescence immunoassa ...

Using distributed interactive simulation (DIS) to conduct effective training, analyses, or mission support in a tactical nuclear weapons effects (NWE) environment requires realistic computer generated forces (CGF) that are sensitive to such effects. This level of sensitivity requires CGF to apply valid and reliable speed-accuracy measures of environmental effects on human performance within the D ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

We propose to design a compact, multiple purpose electromagnetic sensor for monitoring the extremely low frequency (ELF), very low frequency (VLF), and low frequency (LF) spectrum. Our goal is to design a modular, low cost sensor capable of being configured for multiple applications and capable of being employed in remote, unattended sensor networks. We describe three applications or scenarios t ...
