The main purpose of this project was to improve the fundamental mechanistic understanding and quantification of long-term colloid mobilization and colloid-facilitated transport of radionuclides in the vadose zone, with special emphasis on the semi-arid Hanford site. While we focused some of the experiments on hydrogeological and geochemical conditions of the Hanford site, many of our results apply to colloid and colloid-facilitated transport in general. Specific objectives were (1) to determine the mechanisms of colloid mobilization and colloid-facilitated radionuclide transport in undisturbed Hanford sediments under unsaturated flow, (2) to quantify in situ colloid mobilization and colloid-facilitated radionuclide transport from Hanford sediments under field conditions, and (3) to develop a field-scale conceptual and numerical model for colloid mobilization and transport at the Hanford vadose zone, and use that model to predict long-term colloid and colloid- facilitated radionuclide transport. To achieve these goals and objectives, we have used a combination of experimental, theoretical, and numerical methods at different spatial scales, ranging from microscopic investigations of single particle attachment and detachment to larger-scale field experiments using outdoor lysimeters at the Hanford site. Microscopic and single particle investigations provided fundamental insight into mechanisms of colloid interactions with the air-water interface. We could show that a …

This volume summarizes the colloquium, "The Energy and Security Nexus: A Strategic Dilemma." This goal of this event was to explore the connections between energy and security and to consider how best to resolve strategic dilemmas.

The purpose of this report is to provide a concise status update for value-added products (VAP) implemented by the Atmospheric Radiation Measurement (ARM) Climate Research Facility. The report is divided into the following sections: (1) new VAPs for which development has begun, (2) progress on existing VAPs, (3) future VAPs that have been recently approved, (4) other work that leads to a VAP, and (5) top requested VAPs from the archive.

Testimony issued by the Government Accountability Office with an abstract that begins "In summary, TSA receives thousands of air passenger screening complaints through five central mechanisms, but does not have an agencywide policy, consistent processes, or a focal point to guide receipt and use of such information. Also, while the agency has several methods to inform passengers about its complaint processes, it does not have an agencywide policy or mechanism to ensure consistent use of these methods among commercial airports. In addition, TSA's complaint resolution processes do not fully conform to standards of independence to ensure that these processes are fair, impartial, and credible, but the agency is taking steps to improve independence. To address these issues, we made four recommendations to TSA with which the agency concurred, and it indicated actions it is taking in response. Finally, TSA officials stated that the agency is undertaking efforts to focus its resources and improve the passenger experience at security checkpoints by applying new intelligence-driven, risk-based screening procedures, including expanding its Pre✓™ program. TSA plans to have this program in place at 35 airports by the end of the calendar year and estimates that it has screened more than 4 million passengers …

Correspondence issued by the Government Accountability Office with an abstract that begins "Some compliance activities for the export of controlled items under State and Commerce licenses differ from compliance activities under country-based license exemptions, but enforcement activities are generally the same. Compliance activities provide information for exporters, licensing officials, and enforcement agencies to help assess the validity of export transactions, identify potential violations, or prevent violations before they occur. Of the seven compliance activities we identified, three differ for licensed exports compared with country-based license exemptions. These activities are (1) license application review, (2) vetting parties to transactions, and (3) compliance program reviews (recordkeeping). In contrast to these compliance activities, the other four compliance and three enforcement activities, such as inspection of exports, investigations, and punitive actions for violations, are generally the same for both licensed exports and country-based, license-exempt exports."
