Trans-Pacific and regional atmospheric transport of anthropogenic semivolatile organic compounds in the western U.S.

Creator:: Primbs, Toby
Abstract:: The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...

Morphology, ultrastructure and mating of sporidia of a wheat-bunt fungus, Tilletia caries (DC.) Tul.

Creator:: Kollmorgen, James Frederick
Abstract:: The teliospore of Tilletia caries germinates to produce a promycelium with a whorl of primary sporidia at its tip. The time between emergence of the promycelium and the development of primary sporidia averaged 2.3 h. Fusion between compatible sporidia occurred within an additional 3.8 h. Primary sporidia appeared to be...

Evaluation of physical and thermal methods to support nonlinear cost optimization models of surimi seafood

Creator:: Hsü, Cheng-kuang
Abstract:: Optimization programming techniques were applied to develop the least cost formulations for Pacific whiting surimi-based seafood (PWSBS). To develop the quality constraint functions, texture and color of whiting surimi gels were determined by torsion test and colorimeter, respectively. Whiting surimi gels were produced by heating at 90°C for 15 min....

Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

Creator:: Lee, James E.
Abstract:: Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

Understanding Signals of the South Pole Ice Core: Chronology, Climate, and Firn Processes

Creator:: Epifanio, Jenna A.
Abstract:: The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...

The late holocene atmospheric methane budget reconstructed from ice cores

Creator:: Mitchell, Logan E.
Abstract:: Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...

Stable Isotope Constraints on Carbon Dioxide and Nitrous Oxide Variations at the Onset of the Last Glacial Period: New Ice Cores from Taylor Glacier, Antarctica

Creator:: Menking, James A.
Abstract:: New ice cores retrieved from the Taylor Glacier (Antarctica) blue ice area contain ice and air spanning the Marine Isotope Stage (MIS) 5/4 transition, a period of global cooling and ice sheet expansion. Chronologies were determined for the ice and air bubbles in the new ice cores by visually matching...

Cytokinin production by species of the fungus Taphrina

Creator:: Johnston, James Clelland
Abstract:: Chemically defined liquid media were devised which supported excellent growth of Taphrina cerasi and T. deformans. When grown in fermentation culture vessels, T. cerasi and T. deformans released cytokinins into the liquid media. The presence of these cell division factors was demonstrated with the soybean tissue assay which is specific...
