Incorporation of hyperfine probes into the thin-film superconductor YBa₂Cu₃O₇₋δ during deposition

Creator:: Tom, D. W., Platzer, R., Gardner, John A., and Tate, Janet
Abstract:: Radioactive In has been incorporated into oriented thin films of YBa₂Cu₃O₇₋δ during a thermal coevaporation process. The hyperfme technique of perturbed γγ-angular correlation spectroscopy shows that 60% of the indium substitutes at a single site in the superconductor. We obtain spectra with reasonable statistics from 2 mCi of starting material,...

The CP4 transgene provides high levels of tolerance to Roundup® herbicide in field-grown hybrid poplars

Creator:: Meilan, R., Han, K.-H., Ma, C., DiFazio, Stephen P., Eaton, J. A., Hoien, E. A., Stanton, B. J., Crockett, R. P., Taylor, M. L., James, R. R., Skinner, J. S., Jouanin, L., Pilate, G., and Strauss, S. H.
Abstract:: We tested two genes together in hybrid poplars (genus Populus), CP4 and GOX, for imparting tolerance to glyphosate (the active ingredient in Roundup® herbicide). Using Agrobacterium-based transformation, 80 independent transgenic lines (i.e., products of asexual gene transfer) were produced in a variety of hybrid poplar clones (40 lines in Populus...

Hotspots, mantle plumes, flood basalts, and true polar wander

Creator:: Duncan, Robert A. and Richards, M. A.
Abstract:: Persistent, long‐lived, stationary sites of excessive mantle melting are called hotspots. Hotspots leave volcanic trails on lithospheric plates passing across them. The global constellation of fixed hotspots thus forms a convenient frame of reference for plate motions, through the orientations and age distributions of volcanic trails left by these melting...

Tectonically controlled origin of three unusual rock suites in the Woodlark basin

Creator:: Abbott, Dallas and Fisk, Martin R.
Abstract:: We propose alternative mechanisms for the origin of three unusual rock suites, high-Mg andesites, NaTi basalts, and arclike rocks, that have been dredged from the Woodlark basin, southwest Pacific Ocean. We show that the high-Mg andesites and NaTi basalts are associated with an unusually cool ridge environment. The cooling is...

Oceanic germanium/silicon ratios: Evaluation of the potential overprint of temperature on weathering signals

Creator:: Hammond, Douglas E., McManus, James, and Berelson, William M.
Abstract:: Diatom remains indicate the oceanic Ge/Si ratio (μmol/mol) has varied temporally, ranging from Miocene values of 0.9 to Last Glacial Maximum (LGM) values of 0.55, with the present value of 0.69. These ratios lie between those for the primary sources for these elements: continental weathering (Ge/Si = 0.5) and hydrothermal...

Quantitative determination of thermally derived off-flavor compounds in milk using solid-phase microextraction and gas chromatography

Creator:: Vazquez-Landaverde, P. A., Velazquez, G., Torres, J. A., and Qian, M. C.
Abstract:: Many volatile compounds generated during the thermal processing of milk have been associated with cooked, stale, and sulfurous notes in milk and are considered as off-flavor by most consumers. A headspace solid-phase microextraction (HS-SPME)/gas chromatographic technique for the quantitative analysis of thermally derived off-flavor compounds was developed in this study....

The Rise of the Mesopredator

Creator:: Prugh, Laura R., Stoner, Chantal J., Epps, Clinton W., Bean, William T., Ripple, William J., Laliberte, Andrea S., and Brashares, Justin S.
Abstract:: Apex predators have experienced catastrophic declines throughout the world as a result of human persecution and habitat loss. These collapses in top predator populations are commonly associated with dramatic increases in the abundance of smaller predators. Known as “mesopredator release,” this trophic interaction has been recorded across a range of...

Species composition and community structure of pelagic nekton off Oregon and Washington under variable oceanographic conditions

Creator:: Brodeur, Richard D., Fisher, Joseph P., Emmett, Robert L., Morgan, Cheryl A., and Casillas, Ed
Abstract:: Dramatic changes in the physical and biological conditions off Washington and Oregon, USA, have occurred since 1998, including extreme El Niño (warm) and La Niña (cool) years, high and low Columbia River flow years, a major intrusion of subarctic water, and a low oxygen event on the shelf.

Vertical Zoning in Marine Protected Areas: Ecological Considerations for Balancing Pelagic Fishing with Conservation of Benthic Communities

Abstract:: Marine protected areas (MPAs), ideally, manage human uses that threaten ecosystems, or components of ecosystems. During several recent MPA designation processes, concerns have arisen over the scientific justification for no-take MPAs, particularly those that restrict recreational fishing for pelagic species. An important question is: under what conditions might recreational pelagic...

The deglacial transition on the southeastern Alaska Margin: Meltwater input, sea level rise, marine productivity, and sedimentary anoxia

Creator:: Davies, M. H., Mix, A. C., Stoner, J. S., Addison, J. A., Jaeger, J., Finney, B., and Wiest, J.
Abstract:: Oxygen isotope data from planktonic and benthic foraminifera, on a high-resolution age model (44 ¹⁴C dates spanning 17,400 years), document deglacial environmental change on the southeast Alaska margin (59°33.32′N, 144°9.21′W, 682 m water depth).
