Adenosine produces coronary vasodilation through activation of A-2a adenosine receptors. However adalso acts at A1 adenosine receptors to slow atrioventricular conduction and when injected into man ican be blocked with A1 receptor antagonists. DTI has synthesized a number of adenosine analogs that2a subtype of adenosine receptor and have identified WRC-0470 as a potent selective short acting corou ...

This proposal has three main efforts:1. Extension of the ATM Forum ABR protocol to allocate bandwidth according to quality of service (QoS) and priority level of the individual connection. This project will utilize the informational bits provided by the fields to support QoS and priority level acknowledgment.2. Design of an ATM application that utilizes the ABR service via an application programme ...

A completely new method is proposed to remotely measure the true temperature of substrates during chemical vapor deposition (CVD) processes. Conventional radiation pyrometry is not adequate since requires only that the sample be optically polished (specular) and opaque at the measurement wavelengths. These conditions are met for semiconductor and metallic substrates and coating materials of intere ...

Silver thiogallate, AgGaS2[sub], is an attractive nonlinear crystal for the generation of tunable laser radiation from 2 to 12 microns. Its application is limited by surface and bulk absorption. It is proposed to address this absorption problem by characterizing single crystals grown from off-stoichiometric Ag2[sub]S-rich solutions, as well as from conventionally grown crystals from near stoichio ...

The automated inspection of gas turbine components has proven to be difficult due to their complex geometry. While ultrasonics has demomstrated excellent capabilities in detecting and characterizing the erosion and corrosion on turbine components from the hot effluent gases, it's application details laborious alignment procedures for the ultrasonic transducer during inspection. The need for automa ...

In Phase I, we will investigate a case-based reasoning (CBR) approach to intelligent tutoring systems (ITSs) and explore the feasibility of semi-automated/automated course authoring techniques to speed collection and structuring of domain knowledge. We will develop a prototype example-based ITS, enhanced with multimedia, within a specific Navy instructional domain and a generic ITS architec ...
