  • Simple solubility calculations indicate that synthetic Grande Ronde groundwater formulations GR-3 and GR-4 may be unstable with respect to the precipitation of certain components. The validity of calculations of this type is, however, limited by the complexity of the solutions. To address the chemical stability of these formulations properly, an experimental evaluation was performed. The evaluation revealed that GR-3 and GR-4 were similar in their chemical stability. Both were found to be quite stable with respect to all constituents, except silicate and inorganic carbon, over a 30-d period. Some instability of monomeric silicate was observed. However, this did not resultmore » in a concentration change of greater than 5%, and no evidence of particulate formation was observed. Both formulations were found to be relatively unstable with respect to inorganic carbon concentration. A general trend toward increasing carbon concentration was observed. This was attributed to absorption of CO/sub 2/ from the atmosphere. Storing the synthetic groundwater in sealed containers eliminated this problem. 5 refs., 24 tabs.« less
  • Metal matrix composites (MMCs) have been heavily studied over the past thirty years. During that period, many proposals have been made to develop a matrix alloy that was compatible with the reinforcing phase. However, for one reason or another, the technology has continued to focus on conventional alloys and fabrication practices. Although tremendous advances have been made on composite materials, the basic technology remains similar to systems studied twenty years ago. This work represents the first new program where new alloys are being developed for graphite reinforced composites which are tailored to a novel processing technology for manufacturing corrosion resistantmore » graphite reinforced composites.« less

  • The human glucocorticoid receptor (GR) gene produces C-terminal GR{beta} and GR{alpha} isoforms through alternative use of specific exons 9{beta} and {alpha}, respectively. We explored the transcriptional activity of GR{beta} on endogenous genes by developing HeLa cells stably expressing EGFP-GR{beta} or EGFP. Microarray analyses revealed that GR{beta} had intrinsic gene-specific transcriptional activity, regulating mRNA expression of a large number of genes negatively or positively. Majority of GR{beta}-responsive genes was distinct from those modulated by GR{alpha}, while GR{beta} and GR{alpha} mutually modulated each other's transcriptional activity in a subpopulation of genes. We did not observe in HCT116 cells nuclear translocation of GR{beta}more » and activation of this receptor by RU 486, a synthetic steroid previously reported to bind GR{beta} and to induce nuclear translocation. Our results indicate that GR{beta} has intrinsic, GR{alpha}-independent, gene-specific transcriptional activity, in addition to its previously reported dominant negative effect on GR{alpha}-induced transactivation of GRE-driven promoters.« less
