  • John Archibald Wheeler : a study of mentoring in modern physics

    Creator:
    Christensen, Terry M.
    Abstract:
    This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

  • Effects of coupled atomic states on the resonance scattering of radiation

    Creator:
    Srivastava, Rajendra Prasad
    Abstract:
    The excitation and decay probabilities for resonance scattering of radiation from an atom with two coupled excited states and one ground state in an external static field are calculated as a function of time and frequency. Various oscillatory behaviors are found in all the probabilities. These oscillations depend on the...

  • Experimental analysis of subsurface heating and irrigation on the temperature and water content of soils

    Creator:
    Sepaskhah, Ali Reza
    Abstract:
    Multiple use of waste heat from power plants may become an important consideration in the development, siting, and certification of these plants. A multiple use system of components that can beneficially utilize waste heat may include home heating and cooling, greenhouses, animal enclosures, open basins for single cell protein production...

  • Atomic ejection in the single crystal sputtering of nickel with 40-600 eV argon ions

    Creator:
    Leung, Yee Kit
    Abstract:
    A threestage, differentially pumped ion accelerator is used to produce low energy argon ions, which in turn, are used to bombard the surfaces of plane nickel single crystals. Nickel atoms ejected from the crystals are counted using the radioac tive tracing method. From the analysis of the angular distri butions...

  • Perturbed directional correlation in Ta-181

    Creator:
    Sommerfeldt, Raymond Walter
    Abstract:
    The effect of a static quadrupole interaction on the 133-482 Kev gamma-gamma angular correlation in Ta-181 has been studied by the delayed coincidence method. Using a source of Hf-181 in polycrystalline hafnium metal, the anisotropy was measured as a function of time between the formation and decay of the 482...

  • Learning in a physics classroom community : physics learning identity construct development, measurement and validation

    Creator:
    Li, Sissi L.
    Abstract:
    At the university level, introductory science courses usually have high student to teacher ratios which increases the challenge to meaningfully connect with students. Various curricula have been developed in physics education to actively engage students in learning through social interactions with peers and instructors in class. This learning environment demands...

  • Sensemaking Throughout the Physics Curriculum: Understanding Expert and Student Ideas About Sensemaking in a Physics Context

    Creator:
    Lenz, MacKenzie
    Abstract:
    Physics sensemaking is a growing topic of study within the physics education community. Many lenses have been used to study sensemaking but few have considered how time and instruction can impact student sensemaking practices and ideas. In this dissertation, I present four studies that address four major questions: What sensemaking...

  • Cation retention and solute transport related to porosity of pumiceous soils

    Creator:
    Doak, William Herman, 1941-
    Abstract:
    Previous studies of pumiceous soils in Oregon indicated that their physical and chemical properties were strongly related to the porous nature of the pumice matrix. Soils developed on air-fall pumice from the eruption of Mt. Mazama (Crater Lake, Oregon) had low thermal conductivities and low volumetric heat capacities. Values for...

  • Model of student understanding of probability in modern physics

    Creator:
    Wattanakasiwich, Pornrat
    Abstract:
    This study aimed to investigate students' models of probability in a modern physics context. The study was divided into three phases. The first phase explored student pre-knowledge about probability before modem physics instruction. The second phase investigated student understanding of concepts related to probability such as wave-particle behavior, the uncertainty...

  • Mathematical approaches to the physics of mesoscale oceanography

    Creator:
    Early, Jeffrey J.
    Abstract:
    The long-term evolution of Gaussian eddies is studied in an equivalent barotropic model using both linear and nonlinear quasi-geostrophic theory in an attempt to understand westward propagating satellite altimetry tracked mesoscale eddies. By examining both individual eddies and a large basin seeded with eddies, it is shown that long term...
