PROJECT SUMMARY ABSTRACT Over a quarter of primary care patients in the United States can be classified as unhealthy drinkers because their alcohol use conveys a high risk of health and social consequences Unfortunately unhealthy drinking is under recognized in spite of the existence of valid screening tools Even when unhealthy drinking is recognized barriers such as provider discomfort shor ...

Project Summary Atrophic dry age related macular degeneration AMD is the leading cause of severe loss of vision for those over age Dietary supplements containing lutein and zeaxanthin are recommended by the NEI for those at risk of late AMD There has been a corresponding growth in demand for these two xanthophylls Lutein and zeaxanthin are currently sourced from marigolds grown mostl ...

Space platforms are complex dynamical systems and there are many reasons to model them from ground telescope imagery as well as from space-based sensor platforms. One key motivation is to determine the operational state and configuration of the vehicle. Key questions such as did the solar panels fail to deploy, did the object begin to tumble unexpectedly may be addressed by a sufficiently detaile ...

Optical limiters (OL) protect sensitive optical and electronic devices from laser-induced damage. The existing passive OL utilize nonlinear optical materials transmitting low-intensity light, while blocking laser radiation with intensity exceeding certain limiting threshold (LT). The common problem with the existing OL is that, at any particular frequency range, the choice of suitable nonlinear ...

A scalable hybrid lithium ion battery / super capacitor energy storage device is developed and the technology is matured such that the system reduces battery cell stress, improves temperature range, and increases effective battery lifetime and safety. This is an enabling technology that allows the use of very high energy batteries in applications that would otherwise be unsuitable for them.

This Small Business Technology Transfer (STTR) Phase I effort will demonstrate the feasibility of a novel passively adaptive shock and vibration isolating buffer system for the US Navys combatant craft. The proposed approach does not rely on conventional passive, semi-active or active spring-damper systems. The buffer system will provide energy damping via a liquid spring buffer and eddy current d ...

Nevada Composites has developed Green-Aero(sm) toolinglightweight ceramic tooling that is stable under high pressure and long-duration cure cycles and can be washed out with water after cures to 370C (700F). Tools, whether single-sided or washout, have a composite-compatible CTE, provide tight tolerances, are reproducible, are stable to storage under ambient conditions, and are of affordable cost. ...

This Phase II STTR effort is focused on generating the data necessary to identify the phenomenology that produces carbon deposition within kerosene film cooled rocket engines.This data is essential to guide the model development and validation process.Program outputs will be both data and a physics-based model for carbon deposition.

ABSTRACT: Sierra Engineering Inc. (Sierra) believes that existing chemical kinetic models can be efficiently incorporated into commercial CFD codes to predict the mixing, pyrolysis, soot formation and carbon deposition within film cooled rocket engines. During this Phase I STTR effort we will demonstrate that this analysis capability is practical and that we can generate appropriate model validati ...

A hybrid lithium ion battery / super capacitor energy storage device is developed that uses the high power capability of the super capacitor to satisfy pulsed power load requirements such that stress on the lithium ion batteries is reduced. This results in extended discharge time and higher efficiency utilization of the battery stack.
