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...

Seasonal carbohydrate dynamics and growth in Douglas-fir trees experiencing chronic, fungal-mediated reduction in functional leaf area

Creator:: Saffell, Brandy J., Meinzer, Frederick C., Woodruff, David R., Shaw, David C., Voelker, Steven L., Lachenbruch, Barbara, and Falk, Kristen
Abstract:: Stored non-structural carbohydrates (NSCs) could play an important role in tree survival in the face of a changing climate and associated stress-related mortality. We explored the effects of the stomata-blocking and defoliating fungal disease called Swiss needle cast on Douglas-fir carbohydrate reserves and growth to evaluate the extent to which...

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...

Fish Misidentification and Potential Implications to Monitoring Within the San Francisco Estuary, California

Creator:: Kirsch, Joseph E., Day, Julie L., Peterson, James T., and Fullerton, David K.
Abstract:: Fish monitoring programs often rely on the collection, species identification, and counting of individual fish over time to inform natural resource management decisions. Thus, the utility of the data used to inform these decisions can be negatively affected by species misidentification. Fish species misidentification bias can be minimized by confirming...
