Developing X-Ray Spectromicroscopic Techniques To Quantitatively Determine Population Statistics And Individual Particle Composition Of Complex Mixed Aerosols, Matthew Fraund
University of the Pacific Theses and Dissertations
Aerosols are a major source of uncertainty in estimates of anthropogenic effects on global radiative forcing and can pose serious health concerns. While many instrumental techniques capable of analyzing aerosol samples are available, individual-particle spectromicroscopic techniques like the ones presented here are the only ones to offer morphological and compositional measurements together. Studying the composition and mixing state of aerosol populations allowed for important aspects to be uncovered, such as: aerosol source, formation mechanism, hygroscopicity, optical properties, level of aging, and inhalation dangers. Ambient aerosols from the Amazon, both biogenic and anthropogenic, were apportioned based on their individual composition. Recently …

The Carbon Compounds Of The Primeval Atmosphere, James Sherman Rogers
University of the Pacific Theses and Dissertations
The question of how and when life originated on t his planet has always been an intriguing one, exceeded perhaps in fascination only by that area of speculation which concerns itself with death and the afterlife . The latter problem has generally been approached along theological lines; the former problem , that of the origin of life, has been widely investigated along scientific lines as well . Indeed, the origin of life has always been one of the fundamental problems of science, and the increasingly sophisticated answers to the problem reflect the increasing potence and applicability of the methods of …
