  • A preliminary vegetation classification of the Tombstone, Arizona, vicinity

    Creator:
    Garcia-Moya, Edmundo, 1941-
    Abstract:
    The need for classifying vegetation in a more precise way is evident. Also, there is a need to provide a hierarchical classification scheme that will match changes in image characteristics as one moves through the scales from space to conventional aerial photography. Such refined classifications of vegetation are the first...

  • Pool absorption of gas entrained by a plunging liquid jet

    Creator:
    Hauxwell, Gerald Dean
    Abstract:
    A mathematical model was developed to predict the absorption rate of a slightly soluble gas entrained by a plunging liquid jet. The single parameter of the model, the transfer factor, TF, was defined as the summation of the product of the mass transfer coefficient and interfacial area over all the...

  • Measurements of atmospheric sodium abundance by direct absorption of sunlight

    Creator:
    El Tayyan, Ahmed Asad
    Abstract:
    The atmospheric sodium daytime abundance was measured for Corvallis, Oregon, using direct absorption of sunlight by atmospheric sodium atoms, as observed with an optical waveguide spectrum analyzer. The disadvantage of the spectrum analyzer is that it can't resolve the sodium D-lines (Its resolving power is 0.5 nm, which is approximately...

  • College students' alcohol and cannabis use, co-use, academic problems, and gender

    Creator:
    Chupp, Colson D.
    Abstract:
    Objective: Alcohol and cannabis use and co-use among college students is prevalent in the United States (Bravo et al., 2021). These substances have been linked to poor collegiate academic performance in past research. The present study examines varying levels of single-substance alcohol use and alcohol and cannabis co-use in their...

  • Functional consequences of microRNA regulation by polycyclic aromatic hydrocarbons in 3D human bronchial epithelial cells

    Creator:
    Mans, Michael-Andres D.
    Abstract:
    Polycyclic aromatic hydrocarbons (PAHs) are a class of contaminants ubiquitous in the environment and result from the incomplete combustion of fossil fuels. Many PAHs have been identified as procarcinogenic, and are metabolized to form DNA adducts; however, other mechanisms also may contribute to toxicity and help explain differences in toxicity...

  • A Political Ecology Lens for the Nutrition Transition in Rural, Kedougou, Senegal

    Creator:
    Lucey, Taylor K.
    Abstract:
    The nutrition transition is a global phenomenon in which populations move from low socioeconomic status (SES) to high SES and from high physical activity to low physical activity. Rising rates of urbanization and non-communicable diseases in West Africa may indicate an advanced phase of the nutrition transition; however, through a...

  • Properties of veneer sliced from serpentine-end-matched flitches

    Creator:
    Liu, Yuqing
    Abstract:
    Eighteen Ponderosa Pine (Pinus ponderosa Dougl.ex.laws) veneer flitches were randomly selected and crosscut into paired flitches. Serpentine-end-matched (SEM) joints were machined in the flitches, joint amplitude equal to the width in one half of the paired flitch and joint amplitude equal to 2/3 width in the other half of the...
