Framing The View: The *Western Landscape And Nineteenth-Century Narratives Of Expansion., Thomas P. Kinnahan
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study traces the flowering of Western scientific exploration during the fifteen years following the Civil War. During these years, the empirical modes of perception and representation associated with Western exploration gained growing cultural authority and increasingly came to frame discussions of Western policy. At the same time, the systematic exploration of the West revealed the region in new and sometimes startling ways, in some cases prompting far-reaching revisions in the nation's self-perception. The stakes of these revisions became especially acute in the 1870's as the nation's frontier line flowed toward the alien landscapes of the arid West, prompting both …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Plasma sources for optical spectroscopy and mass spectrometry have provided scientists unprecedented knowledge about the fundamental properties and behavior of matter. As informative and useful as these methods are; however, there is still considerable room for improvement. The accuracy and precision of quantitative analyses by mass spectrometry and optical emission spectroscopy are often dependent on the presence of interferences. Interferences are defined as a measured signal response to a species at the spectral position of interest for the analyte that is not caused by the analyte. Because the presence of spectral interferences can deleteriously affect the integrity of reported results, …
