An investigation on the persistence of uranium hydride during storage of simulant nuclear waste packages.
Contributors: Stitt, Camilla
... Synchrotron X-rays have been used to study the oxidation of uranium and uranium hydride when encapsulated in grout and stored in de-ionised water for 10 months. Periodic synchrotron X-ray tomography and X-ray powder diffraction have allowed measurement and identification of the arising corrosion products and the rates of corrosion. The oxidation rates of the uranium metal and uranium hydride were slower than empirically derived rates previously reported for each reactant in an anoxic water system, but without encapsulation in grout. This was attributed to the grout acting as a physical barrier limiting the access of oxidising species to the uranium surface. Uranium hydride was observed to persist throughout the 10 month storage period and industrial consequences of this observed persistence are discussed.

Mozambique (2009): FoQus on HIV Counseling and Testing: A qualitative study to explore motivations and barriers to HIV testing among young men aged 25-40
Contributors: Jennifer Wheeler, Fatima Mussa
... This study aims to gather data useful for designing the following eight elements of the concept for HIV testing aimed at urban and peri-urban men aged 25-40. Between October and December of 2009 PSI Mozambique will conduct a FoQus for Qualitative Segmentation study to gather information about the above-mentioned objectives. In-depth interviews and spoken narratives will be used to collect data. This method was chosen for its ease of use and the rich data that emerge when study participants are given an opportunity to share their personal stories and experiences. Spoken narratives allow researchers (and marketers) to make an emotional connection with the target audience and help create a picture of the "typical" experience.
