Papers 1 - 20 of 6,700 in Miscellaneous, U
  1. Plug-in hybrid electric vehicles (PHEVs) are under evaluation by the U.S.Department of Energy Vehicle Technologies Program's Advanced VehicleTesting Activity and other various stakeholders to better understand theircapability and potential petroleum…
  2. This report documents the guidelines that were used for preparing the U.S. marine mammal stock assessments that are required by the 1994 ammendments to the Marine Mammal Protection Act, as well as the report of the workshop that led to the first…
  3. Previous studies have demonstrated the potential for removal of U(VI) from solution via precipitation of U(VI)-bearing calcium-phosphate (Ca-P) minerals coupled to microbial hydrolysis of glycerol phosphate compounds. We evaluated this process in…
  4. In any statistical analysis, assessing the goodness of fit of a model to the data is crucial to avoid drawing incorrect conclusions. U-CARE is a computer application that deals with the mandatory first steps of the analyses of capture–recapture…
  5. The concept of Ubiquitous Computing Environment leads new paradigm change in urban space creation. In Korea, new concept of Ubiquitous-City (U-City) draws a lot of attentions now. It is trying to fuse high-tech infrastructure and ubiquitous…
  6. Detrital zircon grains (n=468) from eolian sandstones of Permian and Jurassic sand seas on the Colorado Plateau of southwest Laurentia fall into six separable age populations defined by discrete peaks on age-probability plots. The eolian sands…
  7. Building upon the work of Richards et al. [1998. U-Pb dating of a speleothem of Quaternary age. Geochimica et Cosmochimica Acta 62, 3683-3688], we have developed a method for precise dating of speleothems beyond the range of the U-Th technique using…
  8. U-Pb ages for zircon and titanite from a granodioritic gneiss in the Glastonbury Complex, Connecticut, have been determined using both isotope dilution thermal ionization mass spectrometry (TIMS) and the sensitive high resolution ion microprobe…
  9. In order to resolve long-standing issues surrounding the age of the Skhul early modern humans, new analyses have been conducted, including the dating of four well-provenanced fossils by ESR and U-series. If the Skhul burials took place within a…
  10. The decay of uranium in natural materials provides a clock for establishing Quaternary timescales. In particular, reef coral and cave deposit dating has been of crucial importance for calibrating the radiocarbon timescales, establishing sea level…
  11. High-precision (up to ??1-2 years) U-series dating of dead in situ massive Porites corals on the reef flats of Yongshu and Meiji Reefs, Nansha area, southern South China Sea reveals that mortality of these massive corals occurred many times over the…
  12. Pleistocene raised marine deposits in southeastern Tunisia consist of a siliciclastic unit that culminates at + 3 m asl, overlain by a carbonate-rich unit with Strombus bubonius that culminates at + 5 m asl. 234U/238U ratios on fossil Ostraea shells…
  13. Field observations and U-series ages reveal that Shark Bay, Western Australia (WA) has been inundated by the sea on at least three occasions during the Late Pleistocene/Holocene, resulting in a succession of marine deposits around the Bay. The exact…
