[en] The objectives of this study were to evaluate the thermal-hydrological-chemical (THC) effects on flow and geochemistry in the unsaturated zone (UZ) at Yucca Mountain at a mountain scale. The major THC processes important in the UZ are (1) mineral precipitation/dissolution affecting flow and transport to and from the potential repository, and (2) changes in the compositions of gas and liquid that may seep into drifts

[en] Small perch-like fishes from the Oligocene of the Paratethys have been traditionally assigned to Serranus budensis (Heckel, 1856). A morphological revision of the holotype and specimens previously assigned to S. budensis from the Outer Carpathians, Poland, is provided herein. They are re-assigned to the species Oligoserranoides budensis (Heckel, 1856) — Percoidei incertae sedis. New specimens assigned to Ol. budensis from the Outer Carpathians, Poland, are introduced. Our results reveal that Ol. budensis is very similar to the species Caucasoserranoides morozkiensis, Carpathoserranoides brnoensis, Carpathoserranoides polonicus and Oligoserranoides comparabilis, and further studies are necessary to revise the validity of those species. Ol. budensis shares many characters with genera Lutjanus and Ocyurus of the superfamily Lutjanoidea. Ol. budensis differs from Lutjanoidea in having a toothless palatine. The palaeobiogeography of Oligocene small perch-like fishes in the Paratethys is presented and discussed.

[en] This report describes the Licensing Support Network (LSN) Assistant--a set of tools for categorizing e-mail messages and documents, and investigating and correcting existing archives of categorized e-mail messages and documents. The two main tools in the LSN Assistant are the LSN Archive Assistant (LSNAA) tool for recategorizing manually labeled e-mail messages and documents and the LSN Realtime Assistant (LSNRA) tool for categorizing new e-mail messages and documents. This report focuses on the LSNAA tool. There are two main components of the LSNAA tool. The first is the Sandia Categorization Framework, which is responsible for providing categorizations for documents in an archive and storing them in an appropriate Categorization Database. The second is the actual user interface, which primarily interacts with the Categorization Database, providing a way for finding and correcting categorizations errors in the database. A procedure for applying the LSNAA tool and an example use case of the LSNAA tool applied to a set of e-mail messages are provided. Performance results of the categorization model designed for this example use case are presented

[en] Volcanic tuffs under Yucca Mountain on the Nevada Test Site (NTS) are being considered as potential media for geologic disposal of radioactive waste. Calculations in support of site evaluation, repository design, and performance assessment require accurate estimates of the in situ stresses and the variability in the stress state within Yucca Mountain. This paper uses the regional geologic studies that pertain to the stress state at the NTS, stress measurements at Yucca Mountain, and stress measurements in nearby Rainier Mesa, in conjunction with finite element calculations to estimate the in situ stresses at Yucca Mountain. Based on these data, values of lateral earth-stress coefficients (K₀) in the range 0.3 < K₀ < 0.8 are reasonable for repository depths in thermomechanical analyses. 5 figs

[en] In the Sierra Arana area, dextral transcurrent faults form a set of long and narrow E-W tectonic bands, some of which are filled by Oligo-Aquitanian and Cretaceous sediments deeply squeezed among Jurassic carbonates. These bands form a “flower structure” which higher blocks, cut by the faults, fallen over Oligo-Aquitanian sediments, forming a tectonic mélange. The crest zone of Sierra Arana indicates the position of a great reversed south verging anticlinal. The elements situated directly to the south of Sierra Arana, are attributed to a very internal Subbetic or to the Dorsal, and seem to correspond to the paleogeographic passage from the Subbetic to the Malaguide Complex.

[en] Complete text of publication follows. After the installation of geomagnetic observatory 'Abdus Salaam' in Sonmiani (South-west of Pakistan), Pakistan has established another geomagnetic observatory at Islamabad (33.75degN, 72.87degE), located in the North-east mountainous region of the country. Since Pakistan is spread along 23-40degN, 60-80degE, the newly established observatory will provide enhanced coverage of geomagnetic activity in the country. During 2008, repeat station work at three selected sites (Multan, Gilgit and Skardu) was also carried out to compare with the survey work previously done during 2005. All this activity was the result of collaboration between SUPARCO and IRM started in 2006 and which culminated in July 2008 by this joint installation and measurement campaign. Experiences during establishment of the observatory and repeat station comparisons/results are described in this study.
