Abstract:The Smart Adolescent Pregnancy Prevention Tool (SmartAPPT) will study the scientific merit and technical feasibility of a web-based mobile smart phone application to improve knowledge and access to pregnancy prevention information among girls ages 15-17. SmartAPPT is based on the principle that all… more
Abstract:Regular inspection of piping for corrosion damage is crucial in nuclear power plants to prevent leakage of radioactive material into the environment, and to allay concerns of residents living within the vicinity. However, currently used methods for detecting corrosion on interior surfaces of reactor… more
Abstract:ABSTRACT: MetroLaser proposes a test and evaluation methodology to optimize the information return of aero-optic wind tunnel tests, which are corrupted by mechanical vibration. The aero-optic and vibration effects are added and to separate them it would be necessary to accurately measure the effect… more
Abstract:A diagnostic is being developed for aircraft engine exhausts that measures three velocity components in a slice through the plume. The method measures the Doppler shift of laser light scattered from particles naturally present in the flow, such as soot or dust. Two key areas of uncertainty were… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
