There is a critical need for rapid, accurate measurement of serum cholinesterase activity in the field to provide a timely determination of nerve agent exposure. The overall objective of the project is to develop an easy-to-use analytical system consistingof small, inexpensive (and therefore disposable) silicon microchips used with a portable instrument, thus permitting field cholinesterase measur ...

The early genomic responses of human peripheral blood mononuclear cells (PBMCs) to in vitro infection with specific microbial pathogens are being assessed by DNA microarray technology to determine host gene expression

A thermal infrared imaging spectrometer is proposed for the remote detection and identification of surface contaminants. The instrument will use a high power, pulsing CO2 laser to vaporize the liquids while it scans the target scene generating 3Dspectral-images. The instrument will be pre-programmed with a library of contamination filters that can automatically identify contaminants that could b ...

Fabrication of stable, nearly 100% internal carrier collection efficiency silicon photodiodes (AXUV diodes) for 1 nm to 600 nm photons was successfully demonstrated by us several years ago. Owing to their excellent characteristics, these devices are being used by NIST as transfer standards in 5 nm to 250 nm range and aboard SOHO, SNOE and TIMED instruments for the EUV solar spectrum studies. Alt ...

Oceanit showed the feasibility of a low-cost, compact, lightweight, eye-safe LIDAR suitable for aerosol gradient detection in a Phase 1 effort. The system is based on an eye-safe laser being developed at Oceanit as part of a 3D scanning ceilometer. The laser can operate at greater power than other systems using non-eye-safe wavelengths, thus it eliminates many of the problems associated with low ...

An innovative optical system with 500X higher ¿tendu and spatial resolution will be designed for CCD-based bistatic lidar. A 100¿ vertical field of view is required to image the laser beam from the ground through the boundary layer, but only a few degrees are required in the horizontal direction. The proposed design is based on dividing the vertical field of view into N sectors, using 1D rasteri ...

Spray drift is one of the most significant issues presently facing agricultural applicators. Agricultural applicators are committed to the management of chemical drift and take responsibility on a daily basis for making good decisions in the field. Material that drifts off-site is material that is not applied to the target crop or pest and represents both wasted time and wasted material. This equa ...

NON-TECHNICAL SUMMARY: Striped bass culture has become the fourth largest form of fish production in the U.S., trailing only catfish, trout, and salmon in terms of market value. Unfortunately, this promising new industry faces considerable market pressure from foreign competitors who often enjoy lower labor, water, and utility costs and fewer environmental regulations than encountered in the U.S. ...

Hybrid striped bass (HSB) aquaculture has become the fourth largest form of U.S. finfish production, trailing only catfish, trout, and salmon in market value. To compete effectively with low-cost foreign imports, U.S. HSB producers need to develop advanced strains that grow more rapidly and convert feed more efficiently. However, HSB are produced from two parental species (white bass and striped b ...
