Trends in U.S. Global AIDS Spending: FY2000-FY2008

This report describes how HIV/AIDS, tuberculosis (TB), and malaria are interlinked and exacerbate efforts to control each disease, but primarily addresses funding issues related to U.S. global HIV/AIDS initiatives. It provides background information on the key U.S. agencies that implement global HIV/AIDS programs, analyzes U.S. spending on HIV/AIDS by U.S. agency and department, and presents some issues Congress might consider, particularly as debate on the President's Emergency Plan for AIDS Relief (PEPFAR) reauthorization ensues.

Alkaline Leaching of Key, Non-Radioactive Components from Simulants and Hanford Tank Sludge 241-S-110: Results of FY01 Studies (open access)

Alkaline Leaching of Key, Non-Radioactive Components from Simulants and Hanford Tank Sludge 241-S-110: Results of FY01 Studies

This study addressed three aspects in selected alkaline leaching: first, the use of oxidants persulfate, permanganate, and ferrate as selective chromium-leaching agents from washed Hanford Tank S-110 solids under varying conditions of hydroxide concentration, temperature, and time was investigated. Second, the selective dissolution of solids containing mercury(II) oxide under alkaline conditions was examined. Various compounds were studied for their effectiveness in dissolving mercury under varying conditions of time, temperature, and hydroxide concentration in the leachate. Three compounds were studied: cysteine, iodide, and diethyldithiophosphoric acid (DEDTPA). Finally, the possibility of whether an oxidant bound to an anion-exchange resin can be used to effectively oxidize chromium(III) in alkaline solutions was addressed. The experimental results remain ambiguous to date; further work is required to reach any definitive conclusions as to the effectiveness of this approach.
