Penumbra : A Spatiotemporal Shade-Irradiance Analysis Tool with External Model Integration for Landscape Assessment, Habitat Enhancement, and Water Quality Improvement

Creator:: Halama, Jonathan James
Abstract:: Several solar energy models exist, but all models must balance: computational runtime, light complexity, and model output volume. These models span the spectrum of simplistic global solar energy equation sets to complex light ray-tracing models. Spatiotemporally inaccurate representations of solar energy may cause compounding simulation effects and introduce unknown modeling...

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...

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...

Submarine earthquakes, volcanic eruptions and ambient noise in the Northeast Pacific

Creator:: Haxel, Joseph H.
Abstract:: Passive hydrophone technologies and a variety of acoustic methods are applied in the deep-ocean and shallow water coastal environments of the northeast Pacific. A catalog derived from U.S. Navy regional hydrophone array recordings of acoustic T- phases from seafloor earthquakes is examined, describing space/time patterns through empirical orthogonal function analysis...

The influence of monovalent cations on tryptophanase and pyruvate kinase as studied by fluorescence, circular dichroism, and kinetic methods

Creator:: Leete, John Huntington
Abstract:: Two spectrally different species of holotryptophanase were obtained from fluorescence and circular dichroism measurements. One is predominant in solutions containing certain enzyme activating monovalent cations while the other predominates in solutions of various inhibiting monovalent cations. Relative magnitudes of the cation sensitive fluorescent intensity maxima or circular dichroism maxima are...

Forage intake and related performance criteria of spring and fall calving cow-calf pairs on summer range

Creator:: Kartchner, Rex John
Abstract:: Three studies during three consecutive summers were conducted at the Squaw Butte Experiment Station to estimate relative and quantitative forage intake of spring and fall calving cow-calf pairs on summer range. In a drylot study (experiment 1) individual animal consumption of fescue or meadow hay cut at 2- to 10-day...

Inheritance of resistance in some wheat introductions to selected races of bunt, Tilletia caries (DC) Tul and Tilletia foetida (Wallr) Liro

Creator:: Abdalla, Osman S.
Abstract:: Bunt or stinking smut is a major disease of wheat. In the U.S. common bunt, Tilletia caries (DC) Tul. and T. foetida (Wallr) Liro, is a threat to wheat production in the Pacific Northwest. Screening trials conducted by USDA Cereal Investigations Project in Oregon, from 1955-1980, revealed that a number...

John Wesley Powell : science and reform in a positive context

Creator:: Zernel, John Joseph, 1945-
Abstract:: John Wesley Powell worked actively for public land system reform while a director of geographical and geological surveys in the West from 1869 to 1894. Although this has won him acclaim as a conservationist, the basis of Powell's linkage of reform with scientific work is poorly understood. A study of...

Experimental studies on species relationships in T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides

Creator:: Vieira, Luiz Gonzaga E.
Abstract:: A study of populations characteristics of T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides was completed using numerical analysis. A sample of 74 accessions of ssp. carthlicum and 20 of ssp. carthlicoides were scored for 46 characters. It was established that three morphological distinguishable groups of ssp. carthlicum can...

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...
