Global climate change has had a substantial impact on marine biogeography and many species have experienced large spatial redistributions. While many approaches to understanding these changes focus on thermal habitat, theory from physiology and ecology suggest that oxygen and pr…
Isotherm studies on phenolics show a 20-115% increase in uptake due to the presence of oxygen in the test environment, with the additional uptake increasing with decreasing equilibrium concentrations. The same phenomenon is found when oxidizing agents such as hydrogen peroxide a…
A study of adsorption equilibria of oxygen, nitrogen and oxygen-nitrogen mixtures on types 4A, 5A, 13X and Na-Mordenite molecular sieve pellets has been made. Pure component isotherms, using a volumetric apparatus, have been measured for each gas on each adsorbent at pressures u…
Background: A growing body of evidence suggests that a number of perinatal factors may increase the risk of acute lymphocytic leukemia (ALL), the most common childhood cancer. Objective: To better understand perinatal factors associated with ALL with particular attention to oxyg…
This study focuses on the origin and modification of six ultramafic bodies located in the Blue Ridge Province of North Carolina. The bodies consist mainly of harzburgites and dunites with associated chromites. Some of the bodies are associated spatially and genetically with mafi…
Since life took its earliest footholds, organisms have been in a perpetual arms race. Evolutionary trial and error has produced increasingly complex organisms. All with a single purpose, to utilize available resources as efficiently as possible and reproduce. This progression ha…
Isotope ratios of some trace metals have proven useful for tracking Earth’s ocean oxygenation history. As the limitations of some of these isotope systems are realized, it becomes increasingly important to develop new and complementary systems. This dissertation examines the uti…
