Imagining The Internal Reproductive Environment: Function And Evolution Of The Drosophila Melanogaster Female Reproductive Tract, Caitlin Elizabeth Mcdonough-Goldstein

Dissertations - ALL

Sexual reproduction involves complex coordination, and potentially competition, among the reproductive cells, fluids, and structures of all individuals involved. For internally fertilizing species, these interactions occur within the body of one sex, predominantly the female, or ovary-associated, reproductive tract. Thus, characterizing the dynamics of the female reproductive tract is critical to understanding the interactions that mediate reproductive success. Although there has been increasing movement toward revealing the active role of the female reproductive tract in shaping and influencing reproductive outcomes, our knowledge of this environment remains limited as a result of both historical biases and technical constraints. My dissertation advances …

Florida’S Red Tide: The Hidden Costs Of Land Development In The Everglades, Catherine Joan Outman

Student Theses 2015-Present

How does human development of land affect the surrounding ecosystems? This paper explores the development of the Everglades throughout the 1900s, which turned much of this wetland into farmland. Rerouting and restructuring of the Everglades’ remaining waterways has caused fertilizer-rich water from the farms to be dumped into the ocean. This fertilizer pollution has caused aggressive outbreaks of red tide, a toxic algal bloom which depletes the ocean’s oxygen and kills aquatic ecosystems, off the coast of Southwest Florida. Chapter one presents quantitative data about land development in the Everglades, focusing mainly on the amount of wetland before the 1900s …

Validating An Open-Source Uvlm Solver For Analyzing Flapping Wing Flight, Cameron Urban

Mechanical Engineering and Materials Science Independent Study

Scientists have long used the unsteady vortex lattice method (UVLM) to simulate flapping wing flight. However, until recently, there has not been an available open-source UVLM solver designed explicitly for this field. Ptera Software is the only open-source UVLM solver that can simulate flapping wing aerodynamics without the modifications required by other open-source solvers. This report documents the next step in the software’s development: validation of its results. Comparing Ptera Software’s output to high-fidelity experimental data of the pressures on a flapping wing robot shows that the simulated results predict the trends and magnitudes of the net lift over time …

Perioperative Advanced Directives, Derek Washer

Doctor of Nursing Practice Projects

Technology and surgical techniques continue to improve, resulting in more clients with advanced directives presenting to the operative suite for surgery or procedures requiring anesthesia. Anesthesia providers are in a critical position to discuss with the surgical patient or surrogate any alteration or reconsideration to their advanced directive. Unfortunately, patients and anesthesia provider discussions at a North Texas hospital were limited due to a knowledge deficit, an outdated hospital policy rescinding all directives perioperatively, and an inadequate consenting mechanism. The perioperative advanced directives project involved updating the hospital policy to current national guidelines and developing a “DNR Under Anesthesia” consenting …

It is difficult to imagine a focus for research with greater social justification than research about successful educational leadership. Therefore, the purpose of this study is twofold. First, this study explores the “elements” of the Professional Standards of Educational Leaders (PSEL) from the perspective of New Jersey school superintendents to determine what they consider to be most important when formally evaluating New Jersey public school principals. Second, this study will also distinguish what are the essential, compared to important, leadership skills and responsibilities that a building principal must demonstrate as defined by the PSEL standards and determined by Chief School …

Improving The Maximum Power Point Tracking Efficiency Of Photovoltaic Arrays Via Machine Learning And Deep Learning, Sumedha Inamdar

Master of Science in Computer Science Theses

Under partial shading conditions, photovoltaic (PV) modules in a solar array experience varying irradiance. A Global Maximum (GM) and multiple Local Maximums (LMs) can originate on the Power-Voltage (P-V) curve under nonuniform irradiance conditions. There are many maximum power point tracking (MPPT) algorithms developed to detect the true maximum power point (MPP) of a PV array. However, in the real-world environment, limited samples of power-voltage (P-V) data might be available to quickly and accurately predict the position of the global maximum point. Since the change of environmental conditions are dynamic, limited time is available to locate the global peak. Machine …

Malware Classification With Gaussian Mixture Model-Hidden Markov Models, Jing Zhao

Master's Projects

Discrete hidden Markov models (HMM) are often applied to the malware detection and classification problems. However, the continuous analog of discrete HMMs, that is, Gaussian mixture model-HMMs (GMM-HMM), are rarely considered in the field of cybersecurity. In this study, we apply GMM-HMMs to the malware classification problem and we compare our results to those obtained using discrete HMMs. As features, we consider opcode sequences and entropy-based sequences. For our opcode features, GMM-HMMs produce results that are comparable to those obtained using discrete HMMs, whereas for our entropy-based features, GMM-HMMs generally improve on the classification results that we can attain with …

I also provide a list of best practices and I discuss ethical issues. It is common for qualitative researchers to mix techniques in order to creatively address real-world research challenges. The proposed categorization, augmented by the list of best …

Credit Cards, Credit Utilization, And Consumption, Scott Fulford, Scott Schuh

Economics Faculty Working Papers Series

Credit bureau data show remarkably stable consumer utilization of unsecured debt over the business cycle, life cycle, and individually quarter-to-quarter, despite massive variation in available credit. To explain these new findings, we propose a life-cycle consumption model with heterogeneous preferences, endogenous payment choice, and the option to revolve debt for consumption smoothing. Using diary data to identify payment use, the estimated model matches consumption and credit use at every frequency and suggests that around half the population has an endogenously high marginal propensity to consume. The results suggest understanding credit availability and heterogeneous use may lead to richer counter-cyclical policies.

Revisiting The History Of The De Doctrina Christiana Authorship Debate And Its Ramifications For Milton Scholarship: A Response To Falcone And Kerr, David V. Urban

University Faculty Publications and Creative Works

This essay details the history of the De Doctrina Christiana authorship controversy, suggesting that the debate’s conclusion in favor of Miltonic provenance was declared prematurely. It considers Falcone’s and Kerr’s recent essays in light of the larger controversy and proposes that one consequence of the larger debate should be the liberty for scholars to analyze Milton’s theological presentations in his poetry apart from the specter of DDC.

Forfaiting By Waiver As An Alternative To Project Financing For The Realization Of Public-Private Partnership Projects In Poland, Maria Schulders

Studia i Materiały Wydział Zarządzania Uniwersytet Warszawski

Despite growing social infrastructure investment needs, public-private partnership (hereinafter: PPP) is not developing in accordance to expectations in Poland. Only 25% of initiated proceedings conclude in the realization of a contract – a significantly lower rate as compared to other European nations.

Makara Journal of Science

Elevated high-sensitivity C-reactive protein (hs-CRP) levels may be associated with an increased risk of cardiovascular disease (CVD). In general, an individual’s dietary intake may influence the hs-CRP level. However, evidence on the influence of dietary macronutrient intake on hs-CRP levels among obese Malaysian women remains fragmented. Therefore, this study aims to investigate the association between the hs-CRP level and dietary macronutrient intake of obese adults living in Kuantan. The assessment of 24-hour dietary recall and venous hs-CRP levels were investigated in 67 women with a body mass index of 27.5 to 39.9 kg/m². The findings revealed that obese women living …

Figurations Of Timely Extraction, H Pritchard, J Rocha, F Snelting

School of Art, Design and Architecture

During recent years, geocomputation has become increasingly entangled with so-called 4D visualization. The contemporary infrastructure of fossil fuel extraction depends on these software tools for geological data handling, interpretation and modelling of subterranea. This paper makes use of the contaminated and contaminating practice of figuration to plot stories that highlight some of the milestones of deadly collaboration, of optimised acceleration, and of sedimented damage. It engages with three figurations of timely extraction (Consortium, Borehole and Amalgam), to tell stories that provide a way to make present the time-space complexities that emerge from the connections between extractivism, computation and semiotic-material values. …

Automatic Pain Assessment Through Facial Expressions, Ilham Seladji

Theses

Pain is a strong symptom of diseases. Being an involuntary unpleasant feeling, it can be considered as a reliable indicator of health issues. Pain has always been expressed verbally, but in some cases, traditional patient self-reporting is not efficient. On one side, there are patients who have neurological disorders and cannot express themselves accurately, as well as patients who suddenly lose consciousness due to an abrupt faintness. On another side, medical staff working in crowded hospitals need to focus on emergencies and would opt for the automation of the task of looking after hospitalized patients during their entire stay, in …

Control Of Blood Volume Following Hypovolemic Challenge In Vertebrates: Transcapillary Versus Lymphatic Mechanisms., Stanley S. Hillman, Robert C. Drewes, Michael S. Hedrick

Biology Faculty Publications and Presentations

Anurans have an exceptional capacity for maintaining vascular volume compared with other groups of vertebrates. They can mobilize interstitial fluids via lymphatic return at rates that are ten-fold higher than mammals. This extraordinary capacity is the result of coordination of specialized skeletal muscles and pulmonary ventilation that vary volume and pressure of subcutaneous lymph sacs, thus moving lymph to dorsally located lymph hearts that return lymph to the vascular space. Variation in the capacity to mobilize lymph within anurans varies with the degree of terrestriality, development of skeletal muscles, lung volume and lung compliance, and lymph heart pressure development. This …

Traveling-Wave Electrophoresis: 1d Model, Austin Green

Physics Capstone Projects

A 1D model of traveling-wave electrophoresis predicts that molecular diffusion raises the trapping threshold and that other physical properties of the species effect the trapping threshold as well. Small concentrations, below 5μM, raise the trapping threshold for high diffusivity species, resulting in a lower efficiency. Species with a mid-range electrophoretic mobility and diffusivity have their trapping threshold slightly lowered with an increase in concentration, leading to more particles traveling with the wave.
