Characterization And Mechanisms Of Anthocyanin Degradation And Stabilization, Nathan Blaine Stebbins

Graduate Theses and Dissertations

Anthocyanins (ACYs) are polyphenol compounds found in nature, which contribute vivid colors to many fruits and vegetables, while also possessing significant health benefits. These pigments range in color from orange-red to blue-violet and could serve as natural colorants to replace artificial additives. There is a great demand from consumers to have fewer artificial compounds in their foods. However, the relatively instability of ACYs must be further understood in order to limit color degradation before they can completely replace synthetic colorants.

ACYs slowly degrade over time, but there is a knowledge gap on their fate and mechanisms causing degradation. In order …

Mechanistic Studies Of The Iron And Molybdenum Nitrogenases, Derek Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As a basic building block in many biological molecules the element nitrogen (N) is essential for life. Dinitrogen (N2) is abundant in Earth’s atmosphere, but this form is biologically unavailable. To be biologically available N2 must undergo an energy demanding reduction reaction to the fixed form, ammonia (NH3). The industrial Haber-Bosch process, which accounts for approximately 50% of the worlds fixed nitrogen, uses energy from fossil fuels to achieve high pressures and temperatures to facilitate the reaction. The energy used by Haber-Bosch accounts for approximately 2% of the world’s annual supply. The remainder of fixed nitrogen is produced biologically by …

Direct Effects Of Warming Increase Woody Plant Abundance In A Subarctic Wetland, Lindsay G. Carlson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change is expected to continue to cause large increases in temperature in Arctic and sub-Arctic ecosystems which has already resulted in changes to plant communities; for example, increased shrub biomass and range. It is important to understand how warmer temperatures could affect the plant community in a wetland system because this region provides crucial high-quality forage for migratory herbivores during the breeding season. One mechanism by which warming could cause change is directly, where warming influences the vital rates of a species; these effects may be either positive or negative. Warmer temperatures may also affect a species indirectly, by …

Exploring And Describing The Spatial And Temporal Dynamics Of Medusahead In The Channeled Scablands Of Eastern Washington Using Remote Sensing Techniques, Timothy M. Bateman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Medusahead is a harmful weed that is invading public lands in the West. The invasion is a serious concern to the public because it can reduce forage for livestock and wildlife, increase fire frequency, alter important ecosystem cycles (like water), reduce recreational activities, and produce landscapes that are aesthetically unpleasing. Invasions can drive up costs that generally require taxpayer’s dollars. Medusahead seedlings typically spread to new areas by attaching itself to passing objects (e.g. vehicles, animals, clothing) where it can quickly begin to affect plants communities. To be effective, management plans need to be sustainable, informed, and considerate to invasion …

Regulation And Energy Poverty In The United States, Michael C. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Energy poverty is a topic often neglected in the discussion about global climate change. Apocalyptic prophecies about the negative future effects of climate change ignore the suffering of people around the globe whose lives could be drastically improved with access to reliable sources of energy. Though energy poverty from a global perspective is much more serious than energy poverty from a domestic perspective, high home energy bills are a serious cause for concern for many Americans.

This research examines the relationship between regulation, the prices of electricity and natural gas, and the household energy burden, which is the ratio of …

Seasonal Distribution Of Sage-Grouse In Hamlin Valley, Utah And The Effect Of Fences On Grouse And Avian Predators, Heather Hedden Mcpherron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) numbers have declined throughout the western US and are considered a species of concern in most of the eleven states that are within their range. Sage-grouse habitats have been reduced by approximately 44% since European settlement of the Western United States began (Miller et al. 2011). Loss of habitat has contributed to an average decline of sage-grouse populations by 33% across the range (Connelly and Braun 1997). To expand our knowledge of this species, I monitored 16 radio-collared sage-grouse captured from four leks in Hamlin Valley, Utah, USA in 2011 and 2012 …

Relationship Between The Built Environment, Physical Activity, And Chronic Disease Among Individuals With Disabilities In Rural Communities, Nicholas F. Tanner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased risk for chronic disease is closely associated with individual nutrition, tobacco use, and physical inactivity. This thesis focuses on physical activity as a means of preventing select chronic diseases. A major barrier preventing engagement in physical activity is the built environment. Populations residing in rural environment are not afforded the abundance of opportunities for physical activity prevalent in most urban networks. Of the demographic living in rural environments, individuals with disability face additional barriers to physical activity than those without disability. This leads to a higher prevalence of chronic diseases associated with sedentary lifestyles among populations with disability. Few …

Extensions And Improvements To Random Forests For Classification, Anna Quach

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The motivation of my dissertation is to improve two weaknesses of Random Forests. One, the failure to detect genetic interactions between two single nucleotide polymorphisms (SNPs) in higher dimensions when the interacting SNPs both have weak main effects and two, the difficulty of interpretation in comparison to parametric methods such as logistic regression, linear discriminant analysis, and linear regression.

We focus on detecting pairwise SNP interactions in genome case-control studies. We determine the best parameter settings to optimize the detection of SNP interactions and improve the efficiency of Random Forests and present an efficient filtering method. The filtering method is …
