Education of American research astronomers, 1876-1941

Creator:: Hall, Robert Dale, 1947-
Abstract:: The education (particularly graduate education) of Americans who were active in astronomical research between 1876 and 1941 is assessed for its effectiveness in preparing the astronomers for careers in research. This period contains three dynamic changes: the growth of American astronomy in becoming the world's leading community of astronomers, the...

Ionizing radiation and its chemical effects : a historical study of chemical dosimetry (1902-1962)

Creator:: Chorzempa, Mary André, Sister
Abstract:: Chemical dosimetry developed in response to needs created by developments in the field of high-energy radiation. Shortly after the discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious effects of ionizing radiation were recognized. To guard against the injurious effects of radiation in medical application, dose-measuring methods...

Insights into Centennial-Scale Salt Marsh Morphodynamics from the Oregon Coast

Creator:: Peck, Erin K.
Abstract:: Quantification and comparison of morphological changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping this important intertidal zone. Understanding of the rates and drivers of salt marsh change contextualizes intertidal habitats within the sediment routing system (i.e., source...

The development of the chlorinity-salinity concept in oceanography

Creator:: Wallace, William J.
Abstract:: This study traces the historical foundations of the concept of constant ionic proportionality and the equation (Salinity [S%₀] = 1.805 Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography since 1902 until 1969 and which is based upon this constancy, The notion that the constituents present in...

Mediation of conifer root growth by mycorrhizal fungi and plant growth regulators

Creator:: Scagel, Carolyn F.
Abstract:: Many mycorrhizosphere microorganisms can produce plant growth regulating compounds in vitro. Plant growth regulating compounds are known to mediate root growth and development. In reforestation practices, conifer tree seedling growth and survival are linked to rapid root growth and development after outplanting. Multifactorial experiments were conducted to document variations in...

Pulsed laser deposition and thin film properties of p-type BaCuSF, BaCuSeF, BaCuTeF and n-type Zn₂In₂O[subscript 5] wide band-gap semiconductors

Creator:: Kykyneshi, Robert
Abstract:: Thin films of wide band-gap semiconductors are deposited by the pulsed laser deposition method. Optimal deposition parameters for the individual compounds are reported. A family of p-type BaCuQF (Q = S, Se, Te) ceramics with a layered crystalline structure is investigated for active and passive device applications. Epitaxial films of...

Flavor chemistry of butter culture

Creator:: Lindsay, Robert C.
Abstract:: Numerous investigations have been made on the contribution of butter cultures to the flavor of cultured cream butter, but production of uniform cultured cream butter has not been possible in industry. Therefore, it was desirable to investigate in detail the qualitative and quantitative chemistry of the flavor of high quality...

Thresholds of uncertainty : radiation and responsibility in the fallout controversy

Creator:: Jolly, J. Christopher
Abstract:: The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

Exploring urban parks: plant communities, visitor experiences, and manager perspectives in Portland, Oregon

Creator:: Talal, Michelle L.
Abstract:: Urban parks are biodiversity hotspots within cities and have the potential to provide a range of socio-cultural benefits for people, but may not always meet the needs and desires of park visitors. A variety of land use practices and environmental factors affect urban park biodiversity and vegetation structure, composition, and...
