Development of new high-temperature piezoelectric perovskite ceramics

Creator:: Ansell, Troy Youngmin
Abstract:: Lead zirconate titanate (PZT) is the dominant ferroelectric material in the market due to its excellent piezoelectric properties, relatively high Curie transition temperature (T[subscript C]), low cost, etc. However, because of emerging applications with requirements for high temperature (T[subscript C] > 400 °C) ferroelectrics, researchers are increasingly looking at alternative...

Linking nonstructural carbohydrate dynamics to gas exchange and leaf hydraulic behavior in Pinus edulis and Juniperus monosperma

Creator:: Woodruff, David R., Meinzer, Frederick C., Marias, Danielle E., Sevanto, Sanna, Jenkins, Michael W., and McDowell, Nate G.
Abstract:: Leaf hydraulics, gas exchange and carbon storage in Pinus edulis and Juniperus monosperma, two tree species on opposite ends of the isohydry–anisohydry spectrum, were analyzed to examine relationships between hydraulic function and carbohydrate dynamics. Leaf hydraulic vulnerability, leaf water potential (Wl), leaf hydraulic conductance (Kleaf), photosynthesis (A), stomatal conductance (gs)...

Evidence for xylem embolism as a primary factor in dehydration-induced declines in leaf hydraulic conductance

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...

Tertiary geologic framework, neotectonics, and petroleum potential of the Oregon-Washington Continental Margin

Creator:: Snavely, P. D., Jr. and Geological Survey (U.S.)
Abstract:: The Tertiary geologic evolution of the Oregon and Washington continental margin was molded by episodic periods of convergence between the Pacific oceanic plates and the North American plate. This margin is the site of a deep basin that is floored by Paleocene to lower Eocene oceanic crust and contains more...

Reconciling estimates of the contemporary North American carbon balance among terrestrial biosphere models, atmospheric inversions, and a new approach for estimating net ecosystem exchange from inventory-based data

Creator:: Hayes, Daniel J., Turner, David P., Stinson, Graham, McGuire, A. David, Wei, Yaxing, West, Tristram O., Heath, Linda S., de Jong, Bernardus, McConkey, Brian G., Birdsey, Richard A., Kurz, Werner A., Jacobson, Andrew R., Huntzinger, Deborah N., Pan, Yude, Post, W. Mac, and Cook, Robert B.
Abstract:: We develop an approach for estimating net ecosystem exchange (NEE) using inventory-based information over North America (NA) for a recent 7-year period (ca. 2000–2006). The approach notably retains information on the spatial distribution of NEE, or the vertical exchange between land and atmosphere of all non-fossil fuel sources and sinks...

Pre- and Postinfection Activity of Fungicides in Control of Hop Downy Mildew

Creator:: Gent, David H., Twomey, Megan C., Wolfenbarger, Sierra N., and Woods, Joanna L.
Abstract:: Optimum timing and use of fungicides for disease control are improved by an understanding of the characteristics of fungicide physical mode of action. Greenhouse and field experiments were conducted to quantify and model the duration of pre- and postinfection activity of fungicides most commonly used for control of hop downy...

Meta-Analysis Reveals a Critical Period for Management of Powdery Mildew on Hop Cones

Creator:: Nelson, Mark E., Gent, David H., and Grove, Gary G.
Abstract:: Results of 28 field trials conducted over a 12-year period investigating management of hop powdery mildew caused by Podosphaera macularis were quantitatively summarized by meta-analysis to compare product efficacy and use patterns by mode of action as defined by Fungicide Resistance Action Committee (FRAC) groups. Availability of original observations enabled...

Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf

Creator:: Tissot, Brian N., Hixon, Mark Anthony, Barss, William, and Stein, David L.
Abstract:: Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...

A Meta-Analysis of Lesser Prairie-Chicken Nesting and Brood-Rearing Habitats: Implications for Habitat Management

Creator:: Hagen, Christian A., Grisham, Blacke A., Boal, Clint W., and Haukos, David A.
Abstract:: The distribution and range of lesser prairie-chicken (Tympanuchus pallidicinctus) has been reduced by >90% since European settlement of the Great Plains of North America. Currently, lesser prairie-chickens occupy 3 general vegetation communities: sand sagebrush (Artemisia filifolia), sand shinnery oak (Quercus havardii), and mixed-grass prairies juxtaposed with Conservation Reserve Program grasslands....
