  • The Evaluation of Cementitious Pore Solution Composition and Electrical Resistivity Using X-ray Fluorescence (XRF)

    Creator:
    Tsui Chang, Marisol
    Abstract:
    Interest in performance specifications has been growing in the civil and construction industry in the past decade. One major focus area has been on understanding how to prolong the service life of concrete structures, since repair and rehabilitation of existing infrastructure have cost many trillions of dollars. Deterioration mechanisms such...

  • Alternate Methods for the Extraction and Measurement of Pore Solution in Fresh Concrete

    Creator:
    Biever, Joseph
    Abstract:
    Knowledge of the pore solution composition and pore solution resistivity can be helpful for determining the durability of concrete structures. Most notably, pore solution resistivity can be used in the calculation of the formation factor of concrete, which is a ratio of the electrical resistivities of concrete and its pore...

  • Application of Infrared Spectroscopy for Determination of Wood Natural Durability

    Creator:
    Lipeh, Shahlinney
    Abstract:
    Natural durability remains one of the most attractive characteristics of wood, and helps wood obtain a premium price. A worldwide shift towards the use of younger trees from intensively managed forests has created greater concerns about wood quality, especially the wood’s resistance to fungi and insects. Wood durability is assessed...

  • Predicting the Relationships between High School Characteristics and High School Community College Enrollment Rate Using the Oregon Promise.

    Creator:
    Murray-Jensen, Julie
    Abstract:
    Background: Legislators, policy-makers, and leaders in higher education and within communities, are increasingly turning to place-based scholarships, or “promise programs”, to encourage college enrollment and address growing public concerns regarding college affordability. One such program, the Oregon Promise, was implemented across the state of Oregon in the fall of 2016....

  • The Disinformation Dozen and Media Misinformation on Science and Vaccinations

    Creator:
    Mabrey, Benjamin E.
    Abstract:
    The COVID-19 pandemic has shed a light on the need for people to trust in medical science. With the need for 70% of Americans to be vaccinated to achieve herd immunity but 30% have reported vaccine hesitancy, now more than ever do we need to redouble our efforts to ensure...

  • Power Efficient Hybrid Architecture for High Resolution Analog-to-Digital Converters

    Creator:
    Zhang, Hui
    Abstract:
    Analog-to-digital converters (ADCs) are the key building block for sensor applications, such as wireless communications and digital electronics. These applications require ADCs to have medium to high accuracy (normally from 10-14 bits) and relatively low signal bandwidth (ranging from 100Hz-150kHz). Since these applications are often powered by batteries, high power...

  • Assessment of Social Sustainability for the Construction Workforce

    Creator:
    Karakhan, Ali A.
    Abstract:
    Minimal research has focused on the social dimension of sustainability in the built environment especially as it relates to the construction workforce. As a result, there are few to no tools available to industry stakeholders to holistically assess and improve the social sustainability of the construction workforce. Given the high...

  • Transdermal Delivery of Atenolol to Cats

    Creator:
    Mohamed, Sumeia M.
    Abstract:
    This thesis describes in-vitro and in-vivo evaluation of a transdermal atenolol formulation developed at Oregon State University, College of Pharmacy. The formulation was prepared from carbomer as a gel base with propylene glycol, glycerol, ethanol, polysorbate 80 and dimethyl-isosorbide (DMI) as mixture of penetration enhancing agents. The effect of the...

  • A socio-technical study on the improved characterization of stakeholder behaviors and stream temperature in design of watershed conservation practices for climate change adaptation

    Creator:
    Noa-Yarasca, Efrain
    Abstract:
    Characterizing stakeholder behavior when making decisions in watershed management is a great challenge for planners, not only because plans are associated with physical uncertainties but also because stakeholders’ behaviors are influenced by numerous factors. Since stakeholders’ decision-making is linked to multiple types of uncertainty, communication of uncertainty to stakeholders by...
