Using Tree-Ring Data To Analyze The Effects Of Volcanic Eruptions On Climate In Inner Asia From 500 Bce To Present, Jennie Zhu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Volcanic eruptions have influenced regional and global climate on annual, interannual, decadal, and multi-decadal time scales. However, past studies have largely focused on the response of global temperature to modern eruptions with the aid of satellite records. This approach limits the number of eruptions that can be studied and restricts our knowledge to relatively small events when compared to the volcanic history of the late Holocene. I used modern climate records to evaluate the effect of recent eruptions on Mongolian climate. I then extended my analysis to the last 2500 years by examining existing and new tree-ring data from Mongolia …

Effects Of Pristine And Nitrogen-Doped Multi-Walled Carbon Nanotubes On Human Lung Epithelial And Fibroblast Cells, Amy Mihalchik

Graduate Theses, Dissertations, and Problem Reports (ETD)

Multi-Walled Carbon Nanotubes (MWCNT) were first described by Iijima in 1991 as "needle-like tubes" made up of concentric sheets of graphene lattice composed of hexagonal carbon units. MWCNT have been reported to be extremely strong, light-weight, and durable, thus making them a highly valued nanomaterial commercially. In order to improve their electrical conductivity and dispersibility for industrial and biomedical uses, materials scientists began functionalizing CNT in the mid-1990s. One type of functionalized MWCNT, nitrogen doped-MWCNT (ND-MWCNT), have nitrogen directly incorporated into the carbon lattice, disrupting sp2 bonding and decreasing the crystallinity of MWCNT. Nitrogen-doping significantly increases the brittleness, chemical reactivity, …

Brook Trout (Salvelinus Fontinalis) Preference Of Aquatic Versus Terrestrial Prey In Appalachian Headwater Streams, Erin E. Thayer Jan 2016

Brook Trout (Salvelinus Fontinalis) Preference Of Aquatic Versus Terrestrial Prey In Appalachian Headwater Streams, Erin E. Thayer

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis aims to investigate the foraging behavior of Brook Trout (Salvelinus fontinalis), specially focusing on prey preference. Brook Trout are mainly restricted to head-water streams in Appalachia, which is a portion of their native range. These environments generally have low autochthonous materials. Therefore, resident aquatic organisms rely heavily on terrestrial inputs, i.e. leaf litter and terrestrial invertebrates (TI's), to subsidize individual energy requirements at critical times of the year. There is mixed evidence demonstrating stream dwelling trout show either a feeding preference towards aquatic invertebrates (AI's) or towards TI's. Chapter one is an in depth literature review of headwater …

Ordinary Sailors: The French Navy, Vichy And The Second World War, Alexander John Upward Jan 2016

Ordinary Sailors: The French Navy, Vichy And The Second World War, Alexander John Upward

Graduate Theses, Dissertations, and Problem Reports (ETD)

After the debacle of the Fall of France in 1940, the one organization that managed to maintain its discipline and functionality virtually intact was the French Navy. This is the story of how subsequently that navy was able to exert a disproportionate influence on the Vichy regime of Marshal Petain. Such influence achieved its apogee between February 1941 and April 1942 when the navy's Commander-in-Chief Admiral Darlan served simultaneously in several of the regime's highest offices. During this period France continued to flirt with the possibility of actively engaging Great Britain in war on the side of Nazi Germany. It …

Hydroclimatic Assessment Of Changing Climate On Diarrheal Diseases With Reference To Cholera, Fariborz Nasr Azadani Jan 2016

Hydroclimatic Assessment Of Changing Climate On Diarrheal Diseases With Reference To Cholera, Fariborz Nasr Azadani

Graduate Theses, Dissertations, and Problem Reports (ETD)

The association of cholera with the climatic processes is well documented. However the effects of changing climate on occurrence of cholera is not yet evaluated, perhaps due to unavailability of geophysical data and their quantitative linkages with cholera. Global climate models (GCMs) outputs are available at coarse resolution of 200-300km, but the diseases usually occur at 10-15 km, therefore, it is rather challenging to link any GCM outputs with a disease. The goal of this research is to develop algorithms that can link diarrheal diseases with changing climatic conditions. Within this context, cholera is used as a model disease due …

Associations Among Task Self-Efficacy, Physical Activity And Subjective Wellbeing, Abigail M. Nehrkorn Jan 2016

Associations Among Task Self-Efficacy, Physical Activity And Subjective Wellbeing, Abigail M. Nehrkorn

Graduate Theses, Dissertations, and Problem Reports (ETD)

The physical and psychological health benefits resulting from physical activity engagement have been documented in previous literature, including the connection between physical activity and subjective wellbeing (SWB). Associations have also been found between task-related self-efficacy and physical activity, connecting these concepts to Bandura's Social Cognitive Theory (SCT; Bandura, 1982, 1997), such that retaining a higher belief in one's physical activity abilities has been associated with successful physical activity engagement. Previous literature has documented these separate associations, but not as much focus has been placed on examining task self-efficacy, physical activity, and SWB in one model, especially during the time of …
