CHARACTERIZATION OF CYCLED SPHERICAL RESORCINOL-FORMALDEHYDE ION EXCHANGE RESIN (open access)

CHARACTERIZATION OF CYCLED SPHERICAL RESORCINOL-FORMALDEHYDE ION EXCHANGE RESIN

This report presents characterization data for two spherical resorcinol-formaldehyde (sRF) resin beds that had processed cesium in non-radioactive and radioactive cycles. All column cycle operations for the resin beds including loading, displacements, elution, regeneration, breakthroughs, and solution analyses are reported in Nash and Duignan, 2009a. That report covered four ion exchange (IX) campaigns using the two {approx}11 mL beds in columns in a lead-lag arrangement. The first two campaigns used Savannah River Site (SRS) Tank 2F nonradioactive simulant while the latter two were fed with actual dissolved salt in the Savannah River National Laboratory (SRNL) Shielded Cells. Both radioactive cycles ran to cesium breakthrough of the lead column. The resin beds saw in excess of 400 bed volumes of feed in each cycle. Resin disposal plans in tank farm processing depend on characterizations of resin used with actual tank feed. Following a final 30 bed volume (BV) elution with nitric acid, the resin beds were found to contain detectable chromium, barium, boron, aluminum, iron, sodium, sulfur, plutonium, cesium, and mercury. Resin affinity for plutonium is important in criticality safety considerations. Cesium-137 was found to be less than 10E+7 dpm/g of resin, similar to past work with sRF resin. Sulfur levels …

Characterization of Glass-Like Fragments from the 3714 Building (open access)

Characterization of Glass-Like Fragments from the 3714 Building

This report describes characterization of a sample obtained from the 3714 building in the 300 Area. Characterization of this unknown material was required for the demonolition activities in the 300 Area. The object of the study was to dertermine the nature of the material, composition, possible structure, evidence for hazards components. The green material is a sodium alumino-silicate glass. This conclusion is based on the composition provided by SEM-EDS, and the images that suggest a glass-like morphology. Further analysis with Ramin and/or infrared could be used to determine the presence of any organics.

Final technical report for award NO. DE-FG02-95ER20206 (open access)

Final technical report for award NO. DE-FG02-95ER20206

ABSTRACT Initial work focused on the regulation of nitrite reductase, the defining reaction of denitrification as well as nitric oxide (NO) reductase. Expression of the genes encoding both proteins was controlled by NnrR. This regulator was shown to be responsive to NO. More recent work has shown NnrR function is also likely inhibited by oxygen. Therefore, it is this protein that sets the oxygen level at which nitrate respiration takes over from aerobic respiration. The gene encoding NO reductase appears to only require NnrR for expression. Expression of the gene encoding nitrite reductase is more complex. In addition to NnrR, a two component sensor regulator complex termed PrrA and PrrB is also required for expression. These proteins are global regulators and serve to link denitrification with other bioenergetic processes in the cell. They also provide an additional layer of oxygen dependent regulation. The sequencing of the R. sphaeroides 2.4.3 genome allowed us to identify several other genes regulated by NnrR. Surprisingly, most of the genes were not essential for denitrification. Their high level of conservation in related denitrifiers suggests they do provide a selectable benefit to the bacterium, however. We also examined the role of nitrate reductase in contributing to …

Postsecondary Education: College and University Endowments Have Shown Long-Term Growth, While Size, Restrictions, and Distributions Vary (open access)

Postsecondary Education: College and University Endowments Have Shown Long-Term Growth, While Size, Restrictions, and Distributions Vary

A letter report issued by the Government Accountability Office with an abstract that begins "The nation's 4-year not-for-profit colleges and universities collectively held more than $400 billion in endowments in 2008. Some institutions' large endowments coupled with the high and growing cost of college have led to questions about institutions' use of endowments. This mandated report describes (1) the size and change in value of endowments over the last 20 years, (2) the extent and manner to which endowment funds are restricted for financial aid and other purposes, and (3) institutions' distribution of endowment assets. GAO obtained and analyzed data on college and university endowments from the Department of Education and other sources. Because industry-wide data were not available on endowment restrictions and distributions, GAO selected 10 colleges and universities for case studies. The case-study institutions were selected to include a mix of public, private, large, small, and minority-serving institutions. Information from these schools cannot be generalized to all U.S. colleges and universities."

Temporary Assistance for Needy Families: Fewer Eligible Families Have Received Cash Assistance Since the 1990s, and the Recession's Impact on Caseloads Varies by State (open access)

Temporary Assistance for Needy Families: Fewer Eligible Families Have Received Cash Assistance Since the 1990s, and the Recession's Impact on Caseloads Varies by State

A letter report issued by the Government Accountability Office with an abstract that begins "Following sweeping changes made to federal welfare policy in 1996 with the creation of the Temporary Assistance for Needy Families (TANF) program, the number of needy families who received cash assistance fell by more than half to 1.7 million in 2008. Poverty among children also fell from about 21 percent in 1995 to about 16 percent in 2000, rising again to 19 percent in 2008. The current recession deepened in 2008, raising questions about state TANF programs' response to increased needs. GAO was asked to provide Congress with information on the (1) factors contributing to the decline in the number of families receiving assistance; (2) characteristics of participating and nonparticipating eligible families; (3) impact of higher participation in TANF cash assistance on child poverty; and (4) changes states are experiencing in caseloads and spending in the current recession. GAO's methodologies included using microsimulation analyses; reviewing relevant research and federal laws; interviewing TANF officials in 21 selected states; analyzing state cash assistance data; and interviewing researchers, federal officials, and other experts."

An estimate of collisional beam scattering during final focus in NDCX-II (open access)

An estimate of collisional beam scattering during final focus in NDCX-II

The final focus of NDCX-II contains a region with quite high plasma density. We estimate here how much collisional scatter we expect from transit through this plasma. A separate question, not explored here, is how much scatter there might be off of collective fluctuations in the neutralizing plasma, including those driven by the passage of the beam.

Foreign Science and Engineering Presence in U.S. Institutions and the Labor Force (open access)

Foreign Science and Engineering Presence in U.S. Institutions and the Labor Force

The increased presence of foreign students in graduate science and engineering programs and in the scientific workforce has been and continues to be of concern to some in the scientific community. Enrollment of U.S. citizens in graduate science and engineering programs has not kept pace with that of foreign students in those programs. In addition to the number of foreign students in graduate science and engineering programs, a significant number of university faculty in the scientific disciplines are foreign, and foreign doctorates are employed in large numbers by industry. This report explains this issue in detail, as well as probable causes of said incongruity.

Hanford Sludge Simulant Selection for Soil Mechanics Property Measurement (open access)

Hanford Sludge Simulant Selection for Soil Mechanics Property Measurement

The current System Plan for the Hanford Tank Farms uses relaxed buoyant displacement gas release event (BDGRE) controls for deep sludge (i.e., high level waste [HLW]) tanks, which allows the tank farms to use more storage space, i.e., increase the sediment depth, in some of the double-shell tanks (DSTs). The relaxed BDGRE controls are based on preliminary analysis of a gas release model from van Kessel and van Kesteren. Application of the van Kessel and van Kesteren model requires parametric information for the sediment, including the lateral earth pressure at rest and shear modulus. No lateral earth pressure at rest and shear modulus in situ measurements for Hanford sludge are currently available. The two chemical sludge simulants will be used in follow-on work to experimentally measure the van Kessel and van Kesteren model parameters, lateral earth pressure at rest, and shear modulus.

2010 Census: Plans for Census Coverage Measurement Are on Track, but Additional Steps Will Improve Its Usefulness

A letter report issued by the Government Accountability Office with an abstract that begins "Assessing the accuracy of the census is essential given that census data are used to apportion seats in Congress, to redraw congressional districts, and for many other public and private purposes. The U.S. Census Bureau's (Bureau) Census Coverage Measurement program (CCM) is to assess the accuracy of the 2010 Census and improve the design of operations for the 2020 Census. In April 2008, GAO recommended that the Bureau identify how it would relate CCM results--where the 2010 Census was accurate and inaccurate--to census operations to improve future censuses. Knowing where the 2010 Census was inaccurate can help inform research to improve the 2020 Census. GAO was asked to examine (1) the status of CCM planning and (2) the effects of design decisions since GAO issued its April 2008 report. GAO reviewed Bureau documents related to CCM design and National Academy of Sciences reports, and interviewed responsible Bureau officials."
