Water Chemistry And Benthic Macroinvertebrate Ecology In Response To Acid Mine Drainage, Brian Carlson Jan 2013

Water Chemistry And Benthic Macroinvertebrate Ecology In Response To Acid Mine Drainage, Brian Carlson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Benthic macroinvertebrates, especially aquatic insects, are documented indicators of environmental quality, and often respond predictably to changes within a freshwater system. Within West Virginia, acid mine drainage (AMD) forms as a result of oxidizing sulfide rich minerals which occur alongside coal. The resulting effluent is acidic and laden with heavy metals. As a result, valued services and ecological functions provided by freshwater resources are lost. Treatment of AMD is expensive and therefore studies documenting their effect on aquatic resources are valuable. Benthic macroinvertebrate and stream water samples are often used as the deciding factors for the condition of a stream …

Characterization Of Immune Responses To Repeated Aspergillus Fumigatus Exposures, Amanda Dawn Buskirk

Graduate Theses, Dissertations, and Problem Reports (ETD)

Personal exposures to A. fumigatus are associated with a variety of adverse health outcomes, including invasive aspergillosis, allergic sensitization, and asthma. Due to the high rate of mortality associated with invasive disease in immunocompromised patients, most studies of A. fumigatus have aimed to characterize the immune responses in immunocompromised murine models. However, a larger portion of the population is affected by fungal-induced allergies and asthma and the immune mechanisms associated with exposure have rarely been studied in an immunocompetent model. These models do not accurately reflect the natural method of exposure to environmental sources of conidia, and may significantly impact …

The Diabetic Heart: Examination Of The Inner Mitochondrial Membrane, Tara Lyne Slider Croston Jan 2013

The Diabetic Heart: Examination Of The Inner Mitochondrial Membrane, Tara Lyne Slider Croston

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cardiovascular complications, such as diabetic cardiomyopathy, are the primary cause of morbidity and mortality in patients with diabetes mellitus. The hyperglycemic environment associated with diabetes mellitus has been shown to induce the mitochondrial dysfunction contributing to diabetic cardiomyopathy. The examination of mitochondrial function is further complicated by the existence of two spatially and functionally distinct cardiac mitochondrial subpopulations, the subsarcolemmal (SSM) interfibrillar (IFM) mitochondria. These two pools of mitochondria respond differently to pathologic stimuli, such as diabetes mellitus. Targeted by the deleterious effects of diabetes mellitus, the inner mitochondrial membrane (IMM) is composed of a specific lipid environment that houses …

Essays On The Effects Of Womens Rights On Female Brain Drain., Maryam Naghsh Nejad Jan 2013

Essays On The Effects Of Womens Rights On Female Brain Drain., Maryam Naghsh Nejad

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigates the effects of gender discrimination, proxied by a women's rights index, on the female high-skilled migration rates relative to that of male (the female brain drain ratio). First, by developing a model of migration choice I find non-linear effects of gender discrimination on the female brain drain ratio as a result of effects of gender discrimination on both costs and benefits of migration. At low levels of women's rights, increases in the index lead to increases in the female brain drain ratio. At very low levels of women's rights, it is often prohibitively costly for females to …
