Preparation Of Manganese-Doped Carbon Quantum Dots@Halloysite Nanotubes Composites Films For Advanced Uv Shielding Properties, Xiao Zhang, Bin Wang

Turkish Journal of Chemistry

The development of Ultraviolet (UV) shielding materials are of great importance to protect human's health concerns and prevent the degradation of organic matters. However, the synthesis of highly efficient UV shielding polymer nanocomposites is currently limited by the agglomeration of inorganic anti-UV nanoparticles (NPs) within the polymer matrix and limited absorption spectrum of UV shielding agents. In this study, highly effective manganese doped carbon quantum dots@halloysite nanotubes composites (Mn-CDs@HNTs/PAS) were successfully synthesized by loading manganese doped carbon quantum dot (Mn-CDs) into UV shielding effective halloysite nanotubes (HNTs) via solvothermal method, followed by polymerization modification. The results show that inorganic NPs …

Detection of intracellular biothiols (cysteine (CYS), N-acetyl cysteine (NAC) and glutathione (GSH)) with high-selectivity and sensitivity is important to reveal biological functions. 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 …

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 …

Doctoral Dissertations and Projects

The purpose of this transcendental-hermeneutic phenomenological study was to explore and understand the succession planning experiences for pastors at charismatic churches in New Providence, Bahamas. The central phenomenon of succession planning is a complex, intentional, continuous, and systemic organizational process that seeks to identify, develop, appoint, and transfer authority to potential leaders (Barbu, 2024; Lacey, 2003; Rothwell, 2016). The guiding theory was Hersey and Blanchard Situational Leadership II (Sbeih & Jones, 2021). The theory’s primary styles were directing, coaching, supporting, and delegating, and they were integrated with succession planning to consider the charismatic nondenominational Bahamian pastoral experiences. The method of …

A Quantitative Approach To Determining The Reduction Rate Of Cassette Labeling Errors Within A Surgical Pathology Diagnostic Laboratory, Kiaya Symonné Pruitt

Doctoral Dissertations and Projects

Cassette labeling errors within a surgical pathology laboratory can affect patient safety variously, including invalid patient results. In order to diminish these errors, automated systems have been placed in surgical pathology laboratories. However, there is no current research on reducing cassette labeling errors within a surgical pathology laboratory that possesses a partial automated system without a LIS connection. Therefore, the current study aimed to determine if there is a statistically significant reduction in pathology cassette labeling errors during different phases of the barcode system (an automated system) implementation for cassette creation. A nonexperimental correlational design was used for the current …

Perceived Parental Narcissism: The Adult Child's Search Of Romantic Attachment Through Self-Compassion, Deanna A. Bishop

Doctoral Dissertations and Projects

Narcissistic personality disorder is defined by a strong desire for admiration and apathetic responses to others’ emotional needs making bonding in any relationship difficult (American Psychiatric Association, 2022). Healthy bonding within a family environment can be hindered by the lack of empathetic response and agentic behaviors that are characteristic of this personality type (Shaw, 2014). By virtue of innocence and dependency, children are the most vulnerable. The literature illustrates that emotional abuse and neglect, like parental narcissistic abuse, disrupts secure attachment between the parent and the child and can also prevent the child from learning healthy coping mechanisms, such as …

Doctoral Dissertations and Projects

While existing research has indicated the effectiveness of Christian accommodative mindfulness (CAM) to lower symptoms of depression and anxiety, no CAM studies have focused specifically on Christian women of African descent (CWOAD). The aim of this exploratory, case-series study was to examine the effectiveness of the CAM protocol by addressing the participants’ intervention comparison outcomes time (PICOT) question: Among a clinical sample (N = 3) of CWOAD recruited from the waitlist of a Christian counseling center (P) how effective was the CAM protocol (I) indicated by changes over time (C) in the participants’ scores for (1) depression, (2) anxiety/stress, (3) …

The Commonwealth Of Israel: Overcoming The Doctrinal Divide Of Dispensationalism And Covenantalism Through Understanding Pauline Theology, Luke Newton Schier

Doctoral Dissertations and Projects

Beginning in the early part of the twentieth century, a notable theological schism began to emerge within mainstream Christianity which continues to divide evangelicals in the twenty-first century. Accordingly, adherents from both sides have systemized their theologies and developed labels to define their positions. New labels continue to evolve and change as sub-groups emerge into the conversation. Typically, the labels of dispensationalism and covenantalism are employed to identify the differing views; although covenantalism is also referred to as Reformed theology, replacement theology, or supercessionism. More recently, other labels have emerged such as progressive dispensationalism and progressive covenantalism as theologians strive …

Implementation Strategies To Improve Medication Adherence In Adolescents (Aged 13 To 17 Years) With Antipsychotic Induced Weight Gain: Educational Toolkit For Clinicians, Joy Asike

Doctoral Dissertations and Projects

Nonadherence to medication leads to relapses of condition, frequent hospitalization and poor outcomes. Although antipsychotics are effective in the management of mental disorders and psychosis, the side effects, especially weight gain negatively influence medication compliance. Anti-psychotics related to weight gain is one of the most concerning treatment-emergent side leading to a great burden on patients, parents, and clinicians. Obesity and antipsychotic-related weight gain increase the risks to short- and long-term physical health problems such as metabolic syndrome, dyslipidemia, diabetes, hypertension. Evidence has shown that there is generally low guideline adherence regarding the monitoring of antipsychotics, especially in children and adolescents. …

A Study Of Thomas Oord’S Open Theism And Theodicy, Olaoluwa Apata

Doctoral Dissertations and Projects

Open theism’s opposition to the traditional Christian view and its rejection of the classical definitions of God’s attributes, character, and divine impassibility continually creates a point of contention between the two worldviews. As one of the leading voices in this movement, Thomas Oord offers what can be described as a refined argument in support of Open theism in contemporary theological and philosophical studies. His open theism holds that due to God’s kenotic act and uncontrolling love, his ability to know the future is limited and he cannot prevent evil. Oord introduces his version of open theism with the goal of …
