In-Situ Real Time Monitoring and Control of Mold Making and Filling Processes: Final Report (open access)

In-Situ Real Time Monitoring and Control of Mold Making and Filling Processes: Final Report

This project presents a model for addressing several objectives envisioned by the metal casting industries through the integration of research and educational components. It provides an innovative approach to introduce technologies for real time characterization of sand molds, lost foam patterns and monitoring of the mold filling process. The technology developed will enable better control over the casting process. It is expected to reduce scrap and variance in the casting quality. A strong educational component is integrated into the research plan to utilize increased awareness of the industry professional, the potential benefits of the developed technology, and the potential benefits of cross cutting technologies.

EVALUATION OF POTENTIAL ELUANTS FOR NON-ACID ELUTION OF CESIUM FROM RESORCINOL-FORMALDEHYDE RESIN (open access)

EVALUATION OF POTENTIAL ELUANTS FOR NON-ACID ELUTION OF CESIUM FROM RESORCINOL-FORMALDEHYDE RESIN

Small-column ion exchange (SCIX) units installed in high-level waste tanks to remove Cs-137 from highly alkaline salt solutions are among the waste treatment plans in the DOE-complex. Spherical Resorcinol-Formaldehyde (sRF) is the ion exchange resin selected for use in the Hanford Waste Treatment and Immobilization Plant (WTP). It is also the primary ion exchange material under consideration for SCIX at the Hanford site. The elution step of the multi-step ion exchange process is typically done with 0.5 M nitric acid. An acid eluant is a potential hazard in the event of a spill, leak, etc. because the high-level waste tanks are made of carbon steel. Corrosion and associated structural damage may ensue. A study has been conducted to explore non-acid elution as an alternative. Batch contact sorption equilibrium screening tests have been conducted with 36 potential non-acid eluants. The sorption tests involve equilibrating each cesium-containing eluant solution with the sRF resin for 48 hours at 25 C in a shaker oven. In the sorption tests, an eluant is deemed to have a high cesium elution potential if it minimizes cesium sorption onto the sRF resin. The top candidates (based on lowest cesium sorption distribution coefficients) include ammonium carbonate, ammonium carbonate/ammonium …

Globalization, Worker Insecurity, and Policy Approaches

This report discusses the trends driving global economic integration, sources of worker insecurity and policy approaches. There appears to be a range of views on the merits of each of these policy approaches and the extent to which they can be designed and implemented in a way that would reduce worker insecurity without undermining the benefits of globalization.

Globalization, Worker Insecurity, and Policy Approaches

Today's global economy, or what many call globalization, has a growing impact on the economic futures of American companies, workers, and families. The current wave of globalization is supported by three broad trends: technology, increase in world supply of labor, and reduced government policies to international trade and investment.

U.S.-EU Trade and Economic Relations: Key Policy Issues for the 112th Congress

U.S. and European private stakeholders, concerned about slow growth, job creation, and increased competition from emerging economies, have urged Brussels and Washington to strengthen transatlantic trade and economic ties by reducing or eliminating remaining trade barriers and by cooperating more closely in addressing global economic challenges. A select group of these issues are examined in this report.

The International Whaling Convention (IWC) and Legal Issues Related to Aboriginal Rights

This report discusses the recent legislation regarding whaling in general, and aboriginal whaling in particular. Legislative measures, primarily in the form of concurrent resolutions, have been proposed in four categories: protesting commercial, scientific, or community (nonaboriginal) whaling; ensuring aboriginal whaling rights; providing a tax break for aboriginal whaling captains; and addressing the United States' policy at the annual meetings of the IWC.

GAMMA DETECTOR RESPONSE/SOIL CONCENTRATION CORRELATION STUDY AT THE AAR MANUFACTURING, INC. SITE, LIVONIA, MICHIGAN (open access)

GAMMA DETECTOR RESPONSE/SOIL CONCENTRATION CORRELATION STUDY AT THE AAR MANUFACTURING, INC. SITE, LIVONIA, MICHIGAN

At the NRC�s request, ORAU conducted surveys of the AAR Manufacturing site during the period of September 25 through September 27, 2012. The survey activities included walkover surveys and sampling activities. Once the survey team was onsite, the NRC personnel decided to forgo survey activities in the �New Addition� and the pickling area. Areas of the planned study boundary were inaccessible due to overgrowth/large pieces of concrete covering the soil surface; therefore, the study boundary was redefined. Gamma walkover scans of the site boundary and �front yard� identified multiple areas of elevated gamma radiation. As a result, two judgmental samples were collected. Sample results were above thorium background levels The answer to the PSQ relating to the relationship between thorium concentration in soil and NaI instrument response is �Yes.� NaI instrument response can be used as a predictor of Th-232 concentration in the 0 to 1 m layer. An R2 value of 0.79 was determined for the surface soil relationship, thus satisfying the DQOs. Moreover, the regression was cross-checked by comparing the predicted Th-232 soil core concentration to the average Th-232 concentration (Section 5.3.2). Based on the cross-check, the regression equation provides a reasonable estimate for the Th-232 concentration at …

Reach the Bottom Line of the Sbottom Search (open access)

Reach the Bottom Line of the Sbottom Search

We propose a new search strategy for directly-produced sbottoms at the LHC with a small mass splitting between the sbottom and its decayed stable neutralino. Our search strategy is based on boosting sbottoms through an energetic initial state radiation jet. In the final state, we require a large missing transverse energy and one or two b-jets besides the initial state radiation jet. We also define a few kinematic variables to further increase the discovery reach. For the case that the sbottom mainly decays into the bottom quark and the stable neutralino, we have found that even for a mass splitting as small as 10 GeV sbottoms with masses up to around 400 GeV can be excluded at the 95% confidence level with 20 inverse femtobarn data at the 8 TeV LHC.
