Abstract:ABSTRACT: Radio-frequency (RF) transmitting devices are found nearly everywhere today, ranging from lower-power cell phones to radar equipment to high-energy weapons systems. Accidental exposure of humans to the RF radiation emanating from these devices can cause harmful thermal effects including… more
Abstract:Metal casting is an important manufacturing process and most castings are made by small to mid-sized foundries. Sand molded castings account for 85% of all iron and steel castings produced and approximately 5 out of 30 major casting defects including gas blows and sand burn-on are related to poor… more
Abstract:Innovative, fast, ultraprecise and affordable metrology instruments are needed to ensure that grazing incidence optics can meet emerging requirements for DOE Basic Energy Sciences (BES) synchrotron and FEL x-ray light sources. Currently, there is not a suitable instrument available in the United… 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.
