My submission, #4 (9/28/2009, archived online at www.policyscience.net) for your study group urged global health as a new area with emerging, extraordinary opportunities for US leadership, accelerating progress, and strengthening shared humanitarian concerns. As you may recall, I enclosed a copy of a letter of July 21, 2009 to Stephen Groft at NIH re ideas for a Rapid-Learning International Hea...

There has been considerable success over the past five decades in developing a phenomenological and micromechanism-based understanding of lastic flow, creep and superplasticity. Although it is widely known that grain sizes have a distribution in polycrystals and nanocrystals, this factor s usually not included in most analysis of deformation and failure. Experimental observations relating to th...

The fallout of the Enron debacle spurred legislative and regulatory activity aimed at strengthening corporate governance and preventing another corporate implosion. Confronting shattered investor confidence, Congress responded to these corporate governance fiascos by enacting the now infamous Sarbanes-Oxley Act of 2002. The Securities and Exchange Commission (SEC), meanwhile, called on the self...

The microstructural features of variable polarity plasma arc welded Al-Cu-Mg 2024-T351 with 2319 filler have been studied by TEM, SEM and DSC. Fusion zone, partial melting zone, resolutionising zone, overageing (for S phase), peak ageing (for S phase) and under ageing zones (for S phase) have been identified. The Ω phase has been observed between re-solutionising zone and peak ageing zone. The ...

QUESTION Is eight weeks of high-intensity strengthening of the isolated lumbar extensors more effective than low-intensity strengthening or no strengthening? Are any gains maintained 16 weeks later? DESIGN Randomised, three-arm trial with concealed allocation, assessor blinding, and intention-to-treat-analysis. Participants in the waiting list control group were randomised again, after the fi...

This paper discusses the technical dimensions of "quality of care" in contraceptive service delivery in both the Cyclofem Introductory Trial, as well as in routine service delivery of other injectables in Indonesia. Although the quality of care in the Cyclofem trial was generally acceptable, substantial weaknesses in screening, clinical technique, the management of side-effects, and knowledge c...

Solid solution strengthening of the unordered γ matrix phase by alloying elements is great importance during creep Ni-based superalloys, particularly at high temperatures above 1000 °C. To study role different potent solutes, we have conducted experiments on binary Ni-2X alloys (X = Mo, Re, Ta, W) °C, 1050 and 1100 °C a constant stress 20 MPa. Compared to mechanical tests below 800 where size m...

Tailoring the partitioning behavior of solid solution strengtheners is a crucial design strategy for advanced Ni-based superalloys. The goal this study was to maximize enrichment Mo, Re, Ru and W in γ-matrix phase. To determine composition dependency behavior, set polycrystalline superalloys with varying contents these solution-strengthening elements W-containing single-crystalline alloy series...
