Developing Custom Fertilizer Strategies Recirculating Hydroponic Systems, Joshua Bryan Tebow

Graduate Theses and Dissertations

Hydroponic systems recirculate nutrient solution to reduce the amount of water used in leafy green production. However, the rootzone of the nutrient solution is complex and influenced by interacting factors such as plant uptake demand, irrigation water quality, supplied fertilizer salts and nutrient concentrations, environmental conditions, and injection of mineral acids/bases to control solution pH. A common strategy for managing nutrients in commercial production is to select a hydroponic solution formulation (i.e. recipe) to supply and maintain a target pH and electrical conductivity (EC) in the recirculating solution over time by automatic injection of mineral acids/bases and concentrated fertilizer stock …

Implications Of Acetylation And Phosphorylation On Metabolic Enzymes, Nour Fatema

Graduate Theses and Dissertations

All living things depend on glycolysis and the TCA cycle for energy production and metabolic control. Post-translational modifications (PTMs) such as acetylation and phosphorylation, which can change enzyme activity, substrate binding, and overall metabolic balance, tightly regulate these pathways. Diseases like cancer and metabolic problems are associated with disruptions in these alterations.

Serine phosphorylation and lysine acetylation are two of the many PTMs that are evolutionarily conserved processes that alter protein function. Previously thought to be a static histone alteration, acetylation is now understood to be a dynamic regulator of metabolic enzymes that modifies contacts, charge, and conformation. In response …

Assessment Of Nitrogen Source Utilization During Nitrogen Fixation And Nitrogenase Regulation By Methanosarcina Acetivorans, Avery Carter

Biological Sciences Undergraduate Honors Theses

Nitrogen is a crucial element in biomolecules such as proteins and DNA, essential for all cellular life. Biological nitrogen fixation, a process utilized by certain bacteria and archaea, reduces dinitrogen (N₂) to ammonia (NH₃), enabling growth in the absence of fixed nitrogen sources like NH₃. This process is driven by the metalloenzyme nitrogenase, which catalyzes the reaction: N₂ + 16ATP + 8e⁻ + 8H⁺ → 2NH₃ + H₂ + 16ADP + 16Pi. Due to its high energy demand, nitrogenase production and activity are tightly regulated. Among archaea, nitrogenase is found exclusively in methanogens, where its regulation remains poorly understood. We …

An Analysis Of Cellular And Tissue Function Of Lipin In Drosophila Melanogaster, Judah Christian Scott

Graduate Theses and Dissertations

Regulation of energy expenditure and energy storage is a key characteristic of life. Numerous enzymes play a crucial role in regulating energy metabolism. Lipins are a highly conserved family of proteins that function in both lipid synthesis and gene regulation. In the glycerol-3 phosphate pathway, lipins act as a phosphatidate phosphatase (PAP) producing diacylglycerol. In gene regulation, lipins act as transcriptional co-regulators of metabolic genes. The enzymatic PAP activity occurs in the cytoplasm; however, for lipins to function as gene regulators, they must translocate into the nucleus. Nuclear translocation is facilitated by the nuclear localization signal (NLS) within the protein. …

#Girls Gone Viral: Girlification Trends And The Digital Postfeminist Sensibility, Madison Rose Mcbride

Graduate Theses and Dissertations

This thesis provides a critical analysis of viral girlification trends on TikTok to bolster understanding of the rhetoric of popular feminism in the emerging digital landscape. Grounded in feminist cultural theory, this thesis posits that women’s digital engagement influences their notions of self-actualization, their avenues for resisting sexist ideals, and ultimately, their political mobilization. Extending scholarship on postfeminism, I offer two unique but co-constructive features of the postfeminist sensibility: post-irony and the confession paradigm. The first chapter analyzes the “girl dinner” trend as a site of post-ironic discourse. Characterized by ambiguity and ambivalence, post-ironic discourse muddles the line between sincerity …

Polyphenol-Protein Interactions In Pigmented Cereals – A Clean-Label Approach To Tailor Starch Viscosity, Annegret Jannasch

Graduate Theses and Dissertations

Viscosity plays an important role in the food industry as it affects the quality, processing stability, and shelf-life of food and impacts physiological responses such as satiation and satiety. Greater viscosity reduces food intake by increasing the perception of satiety, primarily by delaying gastric emptying and increasing tactile stimulation. Starch is commonly added to food products as a viscosifying ingredient, which often involves chemically modifying the starch via cross-linking, to enhance its resistance to high shear, temperature and acidity. However, chemically modified starches are not “clean-label” ingredients due to the use of toxic chemicals. Therefore, further exploration is needed to …
