Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway(More)
The six competencies of the Accreditation Council for Graduate Medical Education include the lifelong learning skills of evidence-based medicine (EBM)/information mastery. We developed and tested an Objective Structured Clinical Examination (OSCE) station that would measure these skills in family medicine residents. This EBM OSCE station is a 30-minute(More)
This paper details the laboratory processes used to fabricate CdS/CdTe solar cells at the National Renewable Energy Laboratory. The basic fabrication technique includes low-pressure chemical vapor deposited SnO 2 , chemical-bath deposited CdS, close-spaced sublimated CdTe, solution-CdCl 2 treatment, and an acid-contact etch, followed by application of a(More)
Anti-reflection coated (ARC) glass is being used in an increasing percentage of PV modules due to expected higher power and energy output. Assurance of the energy gain and the reliability of the coating is essential to create value. This paper reports on the steps taken to test, qualify, and release in production photovoltaic modules made with ARC glass.(More)
