200-BP-1 Prototype Hanford Barrier Annual Monitoring Report for Fiscal Year 2004

Description: In FY 2004, monitoring of the prototype Hanford barrier focused on barrier stability, vegetative cover, evidence of plant and animal intrusion, and the main components of the water balance. Monitored water-balance components included precipitation, runoff, storage, drainage, and deep percolation. Precipitation in FY 2004 was 26 percent less than in FY 2003 but was still higher than normal. The seasonal distribution in precipitation was also different from the previous year with a 43 percent red… more

Accelerated Testing of the CSNF Waste Form: Applicability to Yucca Mountain

Description: Spent fuel tests in support of Yucca Mountain have been performed for many years. Most of these tests have been either single-pass flowthrough (SPFT) or unsaturated drip tests that have been used to elucidate waste form degradation rates. In general, the tests have been considered accelerated tests per the definition found in ASTM Standard C1174 in that either the temperature or flow rate has been increased in order to increase the rate of alteration. However, as the design and models for the p… more

Activated type I TGFbeta receptor (Alk5) kinase confers enhancedsurvival to mammary epithelial cells and accelerates mammary tumorprogression

Description: The transforming growth factor-betas (TGF{beta}s) are members of a large superfamily of pleiotropic cytokines that also includes the activins and the bone morphogenetic proteins (BMPs). Members of the TGF{beta} family regulate complex physiological processes such cell proliferation, differentiation, adhesion, cell-cell and cell-matrix interactions, motility, and cell death, among others (Massague, 1998). Dysregulation of TGF{beta} signaling contributes to several pathological processes includin… more

Activity Estimates of Various Radionuclides in Saltstone Vapor Phase

Description: Savannah River National Laboratory estimated activities of various radionuclides in vapor phase associated with saltstone. These radionuclides, as well as the estimated activity and concentration of each in the gases phase are listed. Some of the activities are so low they should be considered zero. In particular, activity of the antimony and tin isotopes in the gas phase correspond to less than a molecule of gas per 340 m3 of vapor volume. Equilibrium calculations of the partitioning of each r… more

An Advanced Fracture Characterization and Well Path Navigation System for Effective Re-Development and Enhancement of Ultimate Recovery From the Complex Monterey Reservoir of South Ellwood Field, Offshore California, Quarterly Report: October - December 2004

Description: Venoco Inc, intends to re-develop the Monterey Formation, a Class III basin reservoir, at South Ellwood Field, Offshore Santa Barbara, California. Well productivity in this field varies significantly. Cumulative Monterey production for individual wells has ranged from 260 STB to 8,700,000 STB. Productivity is primarily affected by how well the well path connects with the local fracture system and the degree of aquifer support. Cumulative oil recovery to date is a small percentage of the origina… more

Advanced Heat Transfer and Thermal Storage Fluids

Description: The design of the next generation solar parabolic trough systems for power production will require the development of new thermal energy storage options with improved economics or operational characteristics. Current heat-transfer fluids such as VP-1?, which consists of a eutectic mixture of biphenyl and diphenyl oxide, allow a maximum operating temperature of ca. 300 C, a limit above which the vapor pressure would become too high and would require pressure-rated tanks. The use of VP-1? also su… more
