After 22 years of eruption at Kilauea Volcano, Hawai'i, an environmental, epidemiological, and ethnographic study was conducted to assess for adverse health effects from chronic exposure to volcanogernc air pollution. Environmental data from 2003 indicated that Kau District, from 37 to 74 km downwind from the eruption, was being exposed...
Given image data of a fluid flow, the flow field, < u, v >, governing the evolution of the system can be estimated using a variational approach to optical flow. Assuming that the flow field governing the advection is the symplectic gradient of a stream function or the gradient of...
The purpose of this study was to investigate the distribution
and magnitude of scattered radiation from a typical
mobile radiographic examination as an aid in evaluating
the potential health hazards of the scattered radiation.
Also discussed are current radiation protection standards and
recommendations for mobile radiography.
A Manonite phantom represented...
Increasing numbers of individuals aspire to, seek out, and need a college degree in order to be competitive in the job market (Goyette, 2008; U.S. Department of Education, 2013). College degrees provide access to economic, social, and health benefits (Abel & Deitz, 2014; Autor, 2014). The United States also needs...
In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...
Converting CO2 to valuable materials is attractive.Herein, we report using simple metallothermic reactions to reduce atmospheric CO2 to dense nanoporous graphene. By using a Zn/Mg mixture as a reductant, the resulted nanoporous graphene exhibits highly desirable properties: high specific surface area of 1900 m2/g, a great conductivity of 1050 S/m...

This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
The aim of this dissertation is to develop non-traditional approaches to alternating-current thin-film electroluminescent (ACTFEL) device fabrication. ACTFEL technology suffers from a lack of adequately bright and efficient primary-color phosphors and cannot presently compete in the low-cost display market. Therefore the research presented in this dissertation focuses on an exploration...
Castle Rocks is 12 miles east of Mt. Jefferson, in the central
Cascades of Oregon. The area contains volcanic rocks ranging from
mid-Miocene to Holocene in age. These rocks record alternating
periods of tholeiitic and calc-alkaline volcanism.
The oldest rocks in the area range from basaltic andesite lava
flows to...
A hierarchical series of studies, based mainly on molecular data, was conducted to elucidate the life history of the Douglas-fir Swiss needle cast pathogen Phaeocryptopus gaeumannii at macro- and micro-evolutionary scales. This information was then utilized to design and evaluate molecular diagnostic tools for use in studies on the epidemiology...
A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...
Fifty-seven species of wildlife rely on or frequently use snags for breeding, roosting, or denning in Oregon and Washington. Several publications offer information on use of snags by wildlife, influence of management activities on snags and snag users, and approaches to managing snags to benefit wildlife. Because of the diverse...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
