  • Generation of narrowband THz pulses and THz studies of ultrafast phenomena in semiconductor quantum wells

    Creator:
    Danielson, Jeremy R.
    Abstract:
    This work comprises two main parts: creating and shaping narrowband, pulsed THz radiation in a table-top optical setup; and applying THz pulses to semiconductor nanostructures to study electron dynamics. I developed a scheme to shape the THz output of a fanned-out periodically poled lithium niobate (PPLN) crystal. The pulses are...

  • Loving-Kindness Meditation and Prosocial Construct Activation

    Creator:
    Falkenstein, Angelica R.
    Abstract:
    Both Buddhist and psychological theory postulate that present actions will influence future perceptions, judgments, and behaviors in a concordant manner. While Buddhists explain these effects in the context of karmic theory, psychologists consider these effects of construct activation and chronic construct accessibility. The present study sought to apply social psychological...

  • The role of policy and collaboration in decommissioning exempt water wells in Washington state

    Creator:
    Moran, Kathryn A.
    Abstract:
    The rapid proliferation of exempt wells since the settlement of the West has left the State of Washington with little knowledge of the existing number of exempt wells within its boundaries. Exempt wells are primarily a rural phenomena that when abandoned leave aquifers vulnerable to contaminants and create a general...

  • Blowout and spill occurrence model

    Creator:
    Sim, Lawrence H.
    Abstract:
    To assist with risk-assessment with deepwater and ultra-deepwater prospects for offshore energy extraction as well as provide a useful tool for oil spill response, a spatially-explicit model was developed for comprehensive simulations of a blowout event from the wellhead to final fate and degradation. The Blowout and Spill Occurrence Model...

  • Winter cover cropping effects on integrative biological indicators of soil quality

    Creator:
    Ndiaye, Evelyne L.
    Abstract:
    Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...

  • Using a single-well push-pull test to estimate mass transfer rate parameters

    Creator:
    Kelley, Michael John
    Abstract:
    More efficient methods are needed for the in-situ evaluation of mass transfer parameters which describe the movement of solutes through aquifer material. The objective of this study was to develop a method for estimating diffusion rate and capacity coefficients using a single-well, "push-pull" tracer test. The method consists of the...

  • An evaluation of a water, sanitation, and hygiene (WASH) program for rural communities in northern Afghanistan

    Creator:
    Costello, Denise H.
    Abstract:
    The Water, Sanitation and Hygiene (WASH) sector of international development works to increase access to sustainable, safe water and improved sanitation. Currently, at least 780 million people live without clean drinking water and 2.5 billion without access to improved sanitation (UNICEF & World Health Organization, 2012). Lack of access to...

  • Words of Well-Being : The Relation of an Individual's Word Choice to their Social Well-Being

    Creator:
    Krieger, Katy
    Abstract:
    The present research sought to investigate the relationship between an individual's word choice and their social well-being. In the present investigation, social well-being is a person's social health in relation to their social environment, social network, and ability to interact with others in a social context. This thesis was based...

  • Forensic Hydrogeography : Assessing Groundwater Arsenic Concentrations and Testing Methods within the Harney Basin, Oregon

    Creator:
    Smitherman, Lauren L.
    Abstract:
    Harney County contains defining characteristics of regions containing arsenic within the groundwater such as its location in the western United States, unique closed basin geography, complex geology, and seasonal groundwater level fluctuations. Confirmation of arsenic concentrations above the Maximum Contaminant Level Drinking Water Standard of 10 μg/L has been observed...

  • Family Communication Patterns and Adolescent Emotional Well-being : Cross Classification of Mother-child and Father-child Interactions

    Creator:
    Clark, Adam M.
    Abstract:
    The family as a social unit is the earliest and most fundamental socialization influence and is an important contributor to children's development. Studies of family communication patterns (FCP) have emphasized two particular dimensions--a family's conversation orientation and their conformity orientation. However, many studies of FCP and its related outcomes have...
