Investigating Ammonium Toxicity In The Performance Of Recirculating Periphytic Algal Wastewater Treatment Systems, Oluchuku Richie Ochonogor Jan 2024

Investigating Ammonium Toxicity In The Performance Of Recirculating Periphytic Algal Wastewater Treatment Systems, Oluchuku Richie Ochonogor

Theses and Dissertations

Freshwater nutrient enrichment from wastewater facilities and other sources can lead to freshwater eutrophication, a threat to global aquatic ecosystems. Mechanical and chemical ways to curb this threat are either too expensive or not sustainable, and thus, not feasible. Compared to mechanical and other methods, sustainable, inexpensive biological methods (for example, algal treatment systems) have therefore been developed for the removal of excess nutrients from wastewater. By design, secondary waste treatment facilities (WWTF) remove organics and solids and lower oxygen demanding substances; however, they may not remove enough nutrients to protect freshwater ecosystems in all cases. While algae-based biological methods …


An Exploratory Study Of The Effects Of Bis-Substituted Triazolium Bromide Salts On The Proliferation Of Wi-38 Lung Cells And H-1299 Lung Cancer Cells, Rakaiya Martin Jan 2024

An Exploratory Study Of The Effects Of Bis-Substituted Triazolium Bromide Salts On The Proliferation Of Wi-38 Lung Cells And H-1299 Lung Cancer Cells, Rakaiya Martin

Theses and Dissertations

Lung cancer is the leading cause of cancer deaths worldwide. The battle against this disease continues to challenge physicians and scientists daily, due to its various forms, treatments, and responses. Depending on the grade and stage of the disease, treatments can be extensive, encompassing surgery, chemotherapy, and radiation therapy. Though these therapeutics can prolong a patient’s life, they often have significant ramifications. For instance, radiation therapy has an extensive list of side effects, from organ damage to loss of fertility. These outcomes have driven scientists to explore the applicability of novel cancer treatments. Imidazolium and benzimidazolium salts have been shown …


A Phytochemical Analysis Of Secondary Metabolites In Eupatorium Serotinum, Elise Snow Jan 2024

A Phytochemical Analysis Of Secondary Metabolites In Eupatorium Serotinum, Elise Snow

Theses and Dissertations

Phytochemistry, a subset of Natural Products Chemistry, studies chemically derived products from natural substances. Advances in this field have important applications in medicinal research due to the distinctive and unique properties of natural compounds. All metabolites are produced from the metabolic cycle, which is a pathway that provides energy for the organism. These metabolic compounds vary greatly and are classified based on their function within the organism. Primary metabolites are abundant and contribute to organism growth, development, and maintenance of energy. Secondary metabolites are found in lesser quantity and correlate to natural defense mechanisms. For example, salicylic acid is a …


Optimizing Z/R Relationship For Radar-Based Precipitation Estimates, Jalon Gary Jan 2024

Optimizing Z/R Relationship For Radar-Based Precipitation Estimates, Jalon Gary

Theses and Dissertations

Z/R relationship is a power law relationship between radar reflectivity (Z) and rainfall rate (R). The relationship is expressed as Z = aRb where a and b are correlated with drop size distribution (DSD) and vary across locations. Using a Z/R relationship to translate radar reflectivity to rainfall rate can allow for real-time precipitation monitoring with a high temporal and spatial resolution. A dataset of 12 cases in Georgia from December 2021 to November 2022 was examined using the Georgia Weather Network rain gauge system and the KFFC radar to optimize the best Z/R relationship for each case. Radar-based precipitation …


An Investigation Into Splicing Variation And Expression Patterns Of Insulin-Like Peptide 4 (Ilp4) Within The Drosophila Genus, Zachary C. Griffith Jan 2024

An Investigation Into Splicing Variation And Expression Patterns Of Insulin-Like Peptide 4 (Ilp4) Within The Drosophila Genus, Zachary C. Griffith

Theses and Dissertations

The insulin-signaling pathway plays a crucial role in regulating metabolic homeostasis in both humans and insects. Dysregulation or mutation within this pathway can lead to various diseases, such as diabetes mellitus and insulin resistance. The insulin-like peptide 4 (ILP4) in Drosophila is an interesting subject for study due to its similarity to mammalian insulin and its role in regulating sugar metabolism. In this study, we investigate a novel splicing variation within the Drosophila takahashii Insulin-Like Peptide 4 (ILP4) gene. Our investigation identified a splicing variation found in four Drosophila species that introduces an additional codon in one isoform, resulting in …
