In this study, 2-(2-methoxy-4-methylphenoxy)-3-chloro-5,8-dihydroxynaphthalene-1,4-dione (3) (DDN-O) compound was newly synthesized and used as a fluorogenic probe (detector molecule) in the fluorometric method for the rapid, highly selective and sensitive determination of biothiols. The intensity values (λex = 260 nm, λem = 620 nm) of the product were measured by adding biotihols to the reaction medium at varying concentrations and the glutathione equivalent thiol content (GETC) values of each biotiol were calculated. Using the compoud (3), the reference biotiol …

Understanding Ammonia's Role In Mitigating Concentration Polarization In Anion-Exchange Membrane Electrodialysis, Abdallah Timmaoui, Mahmoud Ferhat, Nesri̇ne Souad Ferhat, Ahmed Hamdi

Turkish Journal of Chemistry

In processes such as electrodialysis, the applied electrical potential is constrained by concentration polarization at the membrane/solution interface. This polarization, which intensifies at higher current densities, impedes ion transport efficiency and may lead to problems such as salt precipitation, membrane degradation, and increased energy consumption. Therefore, understanding concentration polarization is essential for enhancing membrane performance, improving efficiency, and reducing operational costs. This study investigates the impact of ammonia buffer (NH₄⁺/NH₃) on sulfate ion transport through anion-exchange membranes, with a particular focus on limiting current density and concentration polarization under constant current conditions. Our findings demonstrate that ammonia effectively eliminates concentration …

Chilling- And Dark-Regulated Photoprotection In Miscanthus, An Economically Important C4 Grass, Jared Haupt, Katarzyna Glowacka

Department of Biochemistry: Faculty Publications

Tolerance of chilling dictates the geographical distribution, establishment, and productivity of C4 crops. Chilling reduces enzyme rate, limiting the sink for the absorbed light energy leading to the need for quick energy dissipation via non-photochemical quenching (NPQ). Here, we characterize NPQ upon chilling in three Miscanthus accessions representing diverse chilling tolerance in C4 grasses. High chilling tolerant accessions accumulate substantial amounts of zeaxanthin during chilling nights in both field and growth chamber settings. Chilling-induced zeaxanthin accumulation in the dark enhances rate of NPQ induction by 66% in the following morning. Based on our data, the emerging ways for the unique …

George Butterworth’S Musical Contribution To A.E. Housman’S A Shropshire Lad And Bredon Hill And Other Songs, Brenden M. Smith

Masters Theses

​George Butterworth and A.E. Housman were highly influential scholars at the turn of the 20th century. Both men were well known for contributing to folk genres in their corresponding fields. Many famous composers implemented Housman's works, the most conspicuous of which was Butterworth. The composer was tragically killed in World War I in 1916, and today, two song cycles of his remain, both are the poetry of A.E. Housman.

​Butterworth's Shropshire Lad cycles are some of the less-performed works in our classical repertory today because Butterworth abandoned most of his works during World War I. The following paper will give …

Mundane And Magical: How Studio Ghibli Adapts Female Protagonists Toward Gendered Narrative Reconstruction, Lauren F. Frymire

Masters Theses

This paper explores the literary significance of film adaptations, specifically focusing on Studio Ghibli's adaptations of children's novels. Through examining the themes of self-discovery, transformation, and cultural representation in films like *Kiki's Delivery Service*, *Tales from Earthsea*, and *Howl's Moving Castle*, it discusses how Ghibli’s choice of young female protagonists connects with both their original audiences and broader cultural narratives. Drawing on Carl Jung’s theory of the unconscious, Linda Hutcheon's theory of adaptation, and Mariah Chiara Oltolini’s insights on mass media adaptations, the study argues that these films successfully preserve the "magic" of their source material while offering unique, culturally-infused …

Post-Processing National Water Model Long-Range Forecasts With Random Forest Regression In The Cloud To Improve Forecast Accuracy For Decision-Makers And Water Managers, Jacob Matthew Anderson

Theses and Dissertations

Post-processing bias correction of streamflow forecasts can be useful in the hydrologic modeling workflow to fine-tune forecasts for operations, water management, and decision-making. Hydrologic model runoff simulations include errors, uncertainties, and biases, leading to less accuracy and precision for applications in real-world scenarios. We used random forest regression to correct biases and errors in streamflow predictions from the U.S. National Water Model (NWM) long-range streamflow forecasts, considering U.S. Geological Survey (USGS) gauge station measurements as a proxy for true streamflow. We used other features in model training, including watershed characteristics, time fraction of year, and lagged streamflow values, to help …
