Adiabatic Heat of Hydration Calorimetric Measurements for Reference Saltstone Waste (open access)

Adiabatic Heat of Hydration Calorimetric Measurements for Reference Saltstone Waste

The production of nuclear materials for weapons, medical, and space applications from the mid-1950's through the late-1980's at the Savannah River Site (SRS) generated approximately 35 million gallons of liquid high-level radioactive waste, which is currently being processed into vitrified glass for long-term storage. Upstream of the vitrification process, the waste is separated into three components: high activity insoluble sludge, high activity insoluble salt, and very low activity soluble salts. The soluble salt represents 90% of the 35 million gallons of overall waste and is processed at the SRS Saltstone Facility, where it mixed with cement, blast furnace slag, and flyash, creating a grout-like mixture. The resulting grout is pumped into aboveground storage vaults, where it hydrates into concrete monoliths, called saltstone, thus immobilizing the low-level radioactive salt waste. As the saltstone hydrates, it generates heat that slowly diffuses out of the poured material. To ensure acceptable grout properties for disposal and immobilization of the salt waste, the grout temperature must not exceed 95 C during hydration. Adiabatic calorimetric measurements of the heat generated for a representative sample of saltstone were made to determine the time-dependent heat source term. These measurements subsequently were utilized as input to a numerical conjugate …

Agriculture in the U.S.-Dominican Republic Central American Free Trade Agreement (DR-CAFTA) (open access)

Agriculture in the U.S.-Dominican Republic Central American Free Trade Agreement (DR-CAFTA)

On August 2, 2005, President Bush signed into law the bill to implement the Dominican Republic-Central American Free Trade Agreement, or DR-CAFTA (P.L. 109-53, H.R. 3045). In DR-CAFTA, the United States and six countries will completely phase out tariffs and quotas — the primary means of border protection — on all but four agricultural commodities traded between them in stages up to 20 years. The four exempted products are as follows: for the United States, sugar; for Costa Rica, fresh onions and fresh potatoes; and for the four other Central American countries, white corn. DR-CAFTA’s provisions, once fully implemented, are expected to result in trade gains, though small, for the U.S. agricultural sector. This report describes this agreement in detail, as well as the stances of both supporters and detractors.

Angular dependence of dissociative electron attachment topolyatomic molecules: application to the 2B1 metastable state of the H2Oand H2S anions (open access)

Angular dependence of dissociative electron attachment topolyatomic molecules: application to the 2B1 metastable state of the H2Oand H2S anions

The angular dependence of dissociative electron attachment (DEA) to polyatomic targets is formulated in the local complex potential model, under the assumption that the axial recoil approximation describes the dissociation dynamics. An additional approximation, which is found to be valid in the case of H2O but not in the case of H2S, makes it possible to describe the angular dependence of DEA solely from an analysis of the fixed-nuclei entrance amplitude, without carrying out nuclear dynamics calculations. For H2S, the final-vibrational-state-specific angular dependence of DEA is obtained by incorporating the variation of the angular dependence of the entrance amplitude with nuclear geometry into the nuclear dynamics. Scattering calculations using the complex Kohn method and, for H2S, full quantum calculations of the nuclear dynamics using the Multi-Configuration Time-Dependent Hartree method, are performed.

Antibody elbow angles are influenced by their light chain class (open access)

Antibody elbow angles are influenced by their light chain class

We have examined the elbow angles for 365 different Fab fragments, and observe that Fabs with lambda light chains have adopted a wider range of elbow angles than their kappa-chain counterparts, and that the lambda light chain Fabs are frequently found with very large (>195{sup o}) elbow angles. This apparent hyperflexibility of lambda-chain Fabs may be due to an insertion in their switch region, which is one residue longer than in kappa chains, with glycine occurring most frequently at the insertion position. A new, web-based computer program that was used to calculate the Fab elbow angles is also described.
