Evaluating Avian And Aquatic Macroinvertebrate Communities In Wetland Reserve Easements In The Mississippi Alluvial Valley, Kara Michelle Hall

Theses and Dissertations

During the 19th and 20th centuries, nearly 80% of historic bottomland hardwood forests (BLHFs) in the Mississippi Alluvial Valley (MAV) was converted to cropland. Efforts to enhance and restore wetlands on marginal farmland have occurred since the early 1990s through the Wetland Reserve Easement (WRE) and other programs, yet few studies have evaluated ecological impacts of WREs. I conducted avian and aquatic macroinvertebrate surveys across WREs, croplands, and historic minimally disturbed wetlands to index abundance, richness, and diversity. I found WREs had less overall avian abundance, richness, and diversity than reference wetlands, whereas WREs exceeded crop sites in total richness …

Use Of Mid-Infrared Spectroscopy For Estimating Soil Chemical, Physical, And Hydrological Properties In Mississippi And Texas, Kanthake Yasas Bandara Gamagedara

Theses and Dissertations

Accurate and efficient estimation of soil properties is essential for advancing sustainable agriculture, water management, and soil survey applications. Traditional laboratory methods and pedotransfer functions (PTFs) are widely used but are often constrained by high costs, time requirements, and limited scalability. As an alternative, mid-infrared (MIR) and visible–near-infrared (vis–NIR) spectroscopy provide cost-effective, rapid, and non-destructive approaches for soil analysis. However, variability among spectrometer types, geographic regions, and soil scanning conditions poses challenges to model transferability and generalizability. This dissertation evaluated strategies to overcome these challenges and enhance the prediction of soil chemical, physical, and hydrological properties in Mississippi and Texas. …

Evaluating The Effects Of Biostimulants On Apple Coloration, Patrick G. Owens

Theses and Dissertations

Apple peel color is one determining factor of apple quality and is a highly sought after trait by both growers and consumers. Historically plant growth regulators (PGRs) such as daminozide and auxins have been used to induce a greater amount of red color in the peel, but these products typically have negative production impacts and raise environmental concerns. One new area of interest is in called biostimulants. This study investigated the effects of two experimental biostimulants (MCEN1 and MCEN2) applied at varying rates and timings, as well as a commercially available plant growth regulator (Blush® 2X), on ‘Honeycrisp’ apple color …

Space Utilization Optimization, Troy D. Rockwood

Theses and Dissertations

Outer space is a crucial and increasingly leveraged resource for advancing human quality of life; however, its utility is constrained by inherent physical and spectral limitations. This thesis examines two distinct resource optimization problems critical to the sustainable development of space. The first part of this work addresses the optimization of physical orbital space. Unlike a terrestrial resource, mismanagement of this orbital space can lead to a runaway cascade of collisions, destroying the utility of entire orbital regimes. This thesis proposes a conjunction metric to quantify orbital capacity based on Keplerian parameters. We develop a computational tool to measure and …

Drinking Water Treatment Using Microbial Cellulose Membranes, Benjamin Schreiber

Therefore, there is a pressing need for an optimized mixing technique to improve the adsorption …

Fcf India, Arturo Torres Torres Landa, Rachel Lin-Peistrup

Miller Center Fellowship

Afforestation has critically emerged and been widely adopted for ecological restoration and climate change resilience in rural India.

There is a rise in carbon credit schemes and their integration of small farmers into global environmental markets; the relevance of such schemes, however, must not be measured solely by carbon returns. This research explores the larger social, economic, and cultural context of afforestation by conducting a mixed-methods analysis of tree-planting actions undertaken by FCF India, with special regard to the experiences of farmers in Assam. We seek to gauge whether such non-carbon aspects offer transparent and measurable channels of value, and …

Lifetime Prediction Of Electrolytic Capacitors Under Variable Loadings In Electric Vehicles For Prognostics And Health Management Applications, Jaewon Lee

Electronic Dissertations and Theses, 2010-current

Aluminum electrolytic capacitors (AECs) are widely used in electric vehicles (EVs) power electronics but are also a primary source of wear-out failures. Most previously proposed lifetime models were derived under constant loading conditions and therefore cannot capture variable loading arising from seasonal or diurnal temperature swings and user-dependent driving profiles in EVs. This study develops a variable-loading lifetime prediction framework for AECs, which can be further extended to prognostics and health management (PHM). Collectively, the results of the study demonstrate a framework suitable for PHM application, in which SoD-based lifetime prediction yields reliable predictions under variable loadings. An appropriate lifetime …

Variation In Nectar Rewards Under Water Limitation Across Flowering Species, Madeline Isabelle Gregor

Undergraduate Honors Theses

Drought is becoming an increasingly dominant force shaping plant–pollinator interactions, yet we still know little about how nectar rewards respond to water limitation across species commonly used to support pollinators. We examined nectar volume and sucrose content in six flowering species relevant to California’s Mediterranean climate and quantified how drought alters these traits for four of those species. Under well-watered conditions, species differed in their nectar production, spanning more than two orders of magnitude. Perennial species such as Epilobium canum and Scrophularia californica produced the highest nectar volumes and sucrose amounts, suggesting that they contribute substantial carbohydrate resources when moisture …

Subculture And Identity As An Escape From The Societal Norms Of Power Imbalance And Authoritative Abuse, Sarah Goldberg

Master's Theses

By definition, a “bolthole” is an animal’s escape or burrow; or, a person’s escape or place of refuge. It also connotes construction, building, even sculpture - relating proletarian materials to themes of working-class labor and the need for escape. Through sculpture, installation, drawing, and oil painting, Bolthole as a body of work examines power imbalance as a societal norm, and identity and subculture as a rejection of the influence of capitalist institutions. Animal symbolism is used in combination with figurative work and portraiture, directly comparing power imbalances between humans to those in nature; such as predator and prey, parent and …
