A design for an x-ray diffraction teaching device has been
presented. From the design a diffraction device has been constructed.
Based on the principles of the original work by Max von Laue,
a diffraction camera has been constructed using a diagnostic x-ray
machine. The diffraction camera provides a fast, safe,...
Background: The use of a lower extremity injury prevention program (IPP) by female athletes before the completion of puberty may mitigate movement changes that develop during puberty and contribute to greater injury risk. It is unknown whether player age influences coaches’ knowledge, attitudes, and behaviors surrounding IPPs. Methods: Fifty-four female...
The purpose of this thesis is to construct several stochastic
process models for combined statistical dynamic prediction of the
500-millibar pressure surface for the northern hemisphere. To
achieve this, a random forcing function is added to the spectral form
of the nondivergent vorticity equation. Three models, one linear and
two...
This study describes the soils, vegetation and age structure
of the Pinus contorta forests of Crater Lake National Park. Growth
rates of P. contorta, and levels of infection and impact of dwarf
mistletoe (Arceuthobium americanu1r) on growth of P. contorta
individuals are compared among communities.
Vegetation description is based on...
The purpose of this research was to see if there were technological differences in ground stone manufacturing and use from a single site that had been occupied for over 600 years, A.D. 550-A.D. 1150, and had multiple occupations that evolved over time (Late Pithouse Phases, Georgetown, San Francisco, and Three...
