Spalting Fungi : Genetic Identification, Material Interactions and Microscopical Characteristics of Extracted Pigments

Creator:: Vega Gutiérrez, Sarath Mercedes
Abstract:: Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...

Oils Colored with Wood-Staining Fungal Pigments : Color Loss, Oxidation, and Structural Breakdown

Creator:: Hinsch, Eric M.
Abstract:: Wood-staining fungal pigments have potential uses as colorants for wood and textiles. Traditionally, organic solvents have been used as carriers for these pigments. However, other environmentally-friendly and more readily available carriers must be found. Natural oils have the potential to carry these pigments but have demonstrated color loss over relatively...

Simulating Wood Properties in the Context of a Growth and Yield Model for Planted Douglas-fir

Creator:: Osborne, Nathaniel L.
Abstract:: Forest growth and yield models are critical to supporting decision making in forestry, but often lack considerations for wood properties. The feasibility of simulating wood properties in the context of a Douglas-fir individual tree growth and yield model was evaluated. This assessment explored the effect of predicted sapwood width, stem...

Comparative Aquatic Toxicology of Pesticides and Plastics Using the Model Estuarine Fish, Inland Silverside

Creator:: Hutton, Sara J.
Abstract:: Based on current trends both pesticide and plastic production are expected to continue to rise in the coming decade. A growing global population coupled with the effects of climate change are the main drivers of increased pesticide use. Throughout this dissertation pesticides refer to herbicides, fungicides, and insecticides. Plastic production...

Redefining Wellness among Asian American College Students at a Predominantly White Institution through AsianCrit Counter-Storytelling

Creator:: Caldwell-Kan, Sara M.
Abstract:: The dominant narrative of Asian Americans in higher education is one of high achievement, success, and wellness. Dominant voices of white supremacy have primarily constructed this narrative. Asian Americans are regarded as the model minority or the dichotomous “model” while simultaneously maintaining “minority” status. This study centers on seven Asian...

Development of an object-oriented expert system for PWR core reload

Creator:: Greek, Kevin J.
Abstract:: Reactor refueling is a computationally intensive problem solving process that requires automation since significant resources are expended upon the search for an optimal core loading. Without imposing some constraints upon the configurations investigated, an extremely large number of prototype loadings may be generated without discovery of an improved loading. As...

Structural effects of intrinsic and extrinsic perturbations to model membranes

Creator:: Church, Sara E.
Abstract:: The observed and calculated structural parameters of three systems of phosphatidylcholine bilayers in fully-hydrated multilamellar vesicles (MLVs) were determined using x-ray diffraction techniques. The analysis used the x-ray reflections from the low-, intermediateand wide-angle regions of the diffraction patterns in the subgel, gel, rippled and fluid phases to determine the...

Strengthening school readiness for children at risk : evaluating self-regulation measures and an intervention using classroom games

Creator:: Schmitt, Sara A.
Abstract:: In recent years, self-regulation has emerged as a foundational skill for academic success and well-being. Unfortunately, many children enter kindergarten without the self-regulation skills necessary to succeed. Children from high-risk backgrounds (e.g., low-income) are particularly vulnerable for difficulties in self-regulation development. Given these documented gaps in self-regulation, it has become...

Involvement of myristoylated alanine-rich c kinase substrate (MARCKS) protein in prostaglandin F2α- induced secretion of oxytocin by the bovine corpus luteum

Creator:: Salli, Ugur
Abstract:: Prostaglandin F₂α (PGF₂α), a stimulatory hormone of luteal oxytocin secretion, is known to activate protein kinase C (PKC); however, the intracellular signals that promote exocytosis of oxytocin remain to be elucidated. Myristoylated alanine-rich C kinase substrate (MARCKS), a protein specifically phosphorylated by PKC, crosslinks actin filaments associated with the inner...

Human Alteration of a Neotropical Landscape Drives Long-term Changes in its Forest Bird Communities

Creator:: Curtis, Jenna R.
Abstract:: Human alteration of natural landscapes leads to biodiversity loss, often from a combination of area effects and fragmentation effects. Smaller habitat patches support fewer species than large ones and incur additional consequences from isolation. Efforts to preempt biodiversity loss from insular habitat fragments are complicated by individualistic species responses and...
