The goals of the Phase I research period are to construct and test new amperometric biosensors for the determination of several serum enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyltransferase (GGT), which are frequently associated with alcohol-related organ damage and alcoholism. The sensors are based on the selective detection of products formed by r ...

The objective of this proposal is to develop a lithium ion-selective electrode, primarily for application to the clinical determination of lithium in patients undergoing therapy for manic depression. The lithium electrodes currently available are not sufficiently selective for lithium relative to sodium. The selectivity of these electrodes is determined by the metal affinities of organic molecules ...

The cost and limited lifespan of strain gages for stress and vibration surveys has driven researchers to find alternate means of investigating airfoil stress and vibration. Systems based on optical sensors have been reported in the literature since the mid 1960's. These systems have been limited to test cell use and relatively complex, thus preventing their widespread application. One recently d ...

Expendable mine-hunting countermeasures require a propulsion system that is acoustically and magnetically quiet while being light in weight, reliable, and inexpensive. Proposed for development and demonstration is a composite spring energy storage device. Calculations show that a spring weighing only eight pounds can deliver 1/10 horsepower for three to five minutes to power a small vehicle. The ...

Passive detection and classification of missiles, aircraft, and units with internal combustion engines and rocket motors beyond the visual horizon is a capability of substantial tactical significance. Electromagnetic radiation from ions in engines has been identified as a potentially exploitable emission. Ions from combustion have been measured with relatively modest equipment in previous studie ...

PRESENT TRAIN DETECTION SCHEMES RELY LARGELY ON A LOW RESISTANCE THROUGH THE TRAIN'S WHEELS TO PERTURBATE A STABLE ELECTRICAL CIRCUIT. WHILE ELEGANT IN PRINCIPLE, THE DESIGN IS PLAGUED BY OXIDE FILMS AND MATERIAL BUILDUP ON THE RAIL, SNEAK PATHS THROUGH THE BALLAST AND OTHER UNCONTROLLABLE VARIABLES. KVH INDUSTRIES PROPOSES TO DESIGN AND DELIVER A "SMART MAGNETOMETER"-BASED SENSOR PACKAGE WHICH WI ...

Clinically significant delays in language acquisition are the most prevalent developmental problemchildren. Early intervention is crucial since children with language delays are at greatly increaseddisabilities and behavioral disorders, but intervention resources are scarce and insufficient to proindividualized instruction that effective intervention requires. We will develop a computer-based EaIn ...
