In order to develop a stimulating yet effective school-based program which elicits
a positive bone growth response, we need to understand the forces acting on the bones of
children during various high-impact activities. One activity found to promote bone
growth is drop landings from a height. We determined whether there...
This study is the second of a three-part project to determine potential locations for public transient tie-up facilities along the Columbia River. The goal of the three studies is to identify opportunities for developing a network of facilities, which will enable recreational boaters to safely traverse Oregon's portion of the...
A program, Color Choropleth Mapping System (CCMS), has
been developed to provide high quality color choropleth maps at
the Geography Department at Oregon State University. The program
operates interactively and is menu-driven. When developing the
software for mapping programs, programmers need to be aware of
cartographic theory, as well as...
Abstract: A series of 23 thin, mostly mud-silt turbidites are found interspersed between larger, well-dated and regionally correlated paleoseismic sandy turbidites that extend along most of the Cascadia margin, northwestern United States. Investigation of the structure, distribution, and sedimentology of these thin mud-silt units supports the interpretation of these units...
Turbidite deposition along slope and trench settings is evaluated for the Cascadia and Sumatra-Andaman subduction zones. Source proximity, basin effects, turbidity current flow path, temporal and spatial earthquake rupture, hydrodynamics, and topography all likely play roles in the deposition of the turbidites as evidenced by the vertical structure of the...
This dissertation combines volcanological research of three convergent continental margins. Chapters
1 and 5 are general introductions and conclusions, respectively. Chapter 2 examines the spatiotemporal
development of the Altiplano-Puna volcanic complex in the Lípez region of southwest Bolivia, a locus of a
major Neogene ignimbrite flare- up, yet the least...
Osteochondrosis (OC) results from disruption of the normal endochondral ossification process during articular cartilage and epiphyseal bone growth. Previous studies have revealed that cartilage canals are often associated with early OC lesions, especially along the ossification front. In early OC, extracellular matrix signaling pathways are expected to be altered, as...
In response to the increasing pace and scale of wildfire and forest health challenges, the Intertribal Timber Council (ITC) proposed the creation of “Anchor Forests,” where a tribe would convene surrounding landowners to collaboratively manage the entire landscape, across property boundaries. This emergent concept has sparked conversation but has not...
As drop-on-demand (DOD) applications continue to gain ground in desktop inkjet-printing, 3D printing, fluid mixing, and other areas the demand for higher frequency operations are beginning to push against the current physical boundaries in DOD technology. The current research is exploring the possibility of controlling drop volume and velocity at...
The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...
