    A floristic study of Sugarloaf Ridge State Park, Sonoma County, California

    A ist of 400 vascular plants was compiled for Sugarloaf Ridge State Park, a 1142 hectare (2820 acre) park in the outer North Coast Ranges within Sonoma County and adjacent western Napa County, California. Relatively undisturbed stands of native perennial bunchgrasses occur the understory In portions of both the oakwood land and the mixed evergreen forest. Grasslands on serpentine in the park are typically dominated by Nassella. One of the sttlte\u27s eastentmost coast redwood forests occurs in the park. Nonnative Centaurea solstitialis rapidly invades annual grasslands and other disturbed in the park. The California Oepanment of and Recreation (DPR) maintains an active prescribed burn program in an effort to control Cenrournt solstitialis populations. DPR also prescribed burning to retard Pseudotsuga menziesii in oak woodlands. DPR biologists ms believe that fire suppression in this region results in an unnatural type conversion of oak woodlands to mixed evergreen forest

    Co-teaching Botany and History: An Interdisciplinary Model for a More Inclusive Curriculum

    Get PDF
    This essay offers numerous ideas on how to integrate science and history into classroom pedagogy in a way that acknowledges the contributions of women and other groups underrepresented in science by highlighting the cultural and political contexts in which science developed rather than by adding token individuals to a history of science still largely defined by the achievements of a few great men. It details how students in a General Education class co-taught by a botanist and a historian of science at the Evergreen State College not only gained skills in field botany and vegetation analysis but also became more informed about how modern scientific disciplines took shape. Recognizing that race, class, and gender have played a role in how science developed, the students’ understanding of the complicated legacy of scientific inquiry gave them tools to be more rigorous in their thinking about scientific practice. This interdisciplinary approach, so crucial in fostering inclusivity in scientific disciplines, also promoted a deeper engagement with historical inquiry

    Improving Internal Hiring Practices at the Oregon Employment Department

    Examining committee: Colleen ChrisingerThe purpose of this report is to provide useful recommendations to aid the Oregon Employment Department (OED) in improving its internal recruitment process. A team of HR employees within the agency identified room for improvement in its traditional hiring model and reached out to a group of University of Oregon graduate students for fresh ideas. The student research team examined current literature, online resources, and the advice of hiring experts to form a list of current industry strategies and innovative ideas not currently utilized by OED. As the HR team originally surmised, the student researchers concluded that OED’s recruitment procedures are quite rigid and bureaucratic. It appears that the agency could improve the process in order to recruit a truly exceptional team of staff. There are exceptional candidates out looking for work and OED can hire more of them if it refreshes its hiring strategies, especially where it publicizes positions and how it uses interviews to select the best possible candidates. If OED is able to make beneficial changes, the agency will connect with a larger quantity of high-quality candidates and consequently bring more of them on board. This report contains a wide range of practices that could be incorporated at OED to breathe new life into the agency. The intention of the student researchers is for the HR team to review the recommendations provided here, discuss the implications of each strategy, determine which would be the most successful at OED, and incorporate those into a tool for hiring managers to use when recruiting new employees

    Low-Speed Wind Tunnel Tests of Two Waverider Configuration Models

    Get PDF
    A definitive measurement of the low-speed flight characteristics of waverider-based aircraft is required to augment the overall design database for this important class of vehicles which have great potential for efficient high-speed flight. Two separate waverider-derived vehicles were tested; one in the 14- by 22-Foot Tunnel and the other in the 12-Foot Low Speed Tunnel at Langley Research Center. These tests provided measurements of moments and forces about all three axes, control effectiveness, flow field characteristics and the effects of configuration changes. The results of these tunnel tests are summarized and the subsonic aerodynamic characteristics of the two configurations are shown

    Superconductors with Magnetic Impurities: Instantons and Sub-gap States

    Full text link
    When subject to a weak magnetic impurity potential, the order parameter and quasi-particle energy gap of a bulk singlet superconductor are suppressed. According to the conventional mean-field theory of Abrikosov and Gor'kov, the integrity of the energy gap is maintained up to a critical concentration of magnetic impurities. In this paper, a field theoretic approach is developed to critically analyze the validity of the mean field theory. Using the supersymmetry technique we find a spatially homogeneous saddle-point that reproduces the Abrikosov-Gor'kov theory, and identify instanton contributions to the density of states that render the quasi-particle energy gap soft at any non-zero magnetic impurity concentration. The sub-gap states are associated with supersymmetry broken field configurations of the action. An analysis of fluctuations around these configurations shows how the underlying supersymmetry of the action is restored by zero modes. An estimate of the density of states is given for all dimensionalities. To illustrate the universality of the present scheme we apply the same method to study `gap fluctuations' in a normal quantum dot coupled to a superconducting terminal. Using the same instanton approach, we recover the universal result recently proposed by Vavilov et al. Finally, we emphasize the universality of the present scheme for the description of gap fluctuations in d-dimensional superconducting/normal structures.Comment: 18 pages, 9 eps figure

    Untargeted metabolomics and metagenomics reveal signatures for intramammary ceftiofur treatment and lactation stage in the cattle hindgut

    Get PDF
    The gut microbiota in cattle is essential for protein, energy, and vitamin production and hence, microbiota perturbations can affect cattle performance. This study evaluated the effect of intramammary (IMM) ceftiofur treatment and lactation stage on the functional gut microbiome and metabolome. Forty dairy cows were enrolled at dry-off. Half received IMM ceftiofur and a non-antibiotic teat sealant containing bismuth subnitrate (cases), while the other half received the teat sealant (controls). Fecal samples were collected before treatment at dry off, during the dry period (weeks 1 and 5) and the first week after calving (week 9). Shotgun metagenomic sequencing was applied to predict microbial metabolic pathways whereas untargeted metabolomics was used identify polar and nonpolar metabolites. Compared to controls, long-term changes were observed in the cows given ceftiofur, including a lower abundance of microbial pathways linked to energy production, amino acid biosynthesis, and other vital molecules. The metabolome of treated cows had elevated levels of stachyose, phosphatidylethanolamine diacylglycerol (PE-DAG), and inosine a week after the IMM ceftiofur application, indicating alterations in microbial fermentation, lipid metabolism, energy, and cellular signaling. Differences were also observed by sampling, with cows in late lactation having more diverse metabolic pathways and a unique metabolome containing higher levels of histamine and histamine-producing bacteria. These data illustrate how IMM ceftiofur treatment can alter the functionality of the hindgut metabolome and microbiome. Understanding how antibiotics and lactation stages, which are each characterized by unique diets and physiology, impact the function of resident microbes is critical to define normal gut function in dairy cattle
