Dissolved Nitrogen Removal In Biochar Amended, High Permeability Media For Urban Stormwater Treatment, Mark Vicciardo

USF Tampa Graduate Theses and Dissertations

Nutrient pollution in stormwater drives the eutrophication of inland and costal waterbodies which leads to sea grass retreat and the proliferation of harmful algal blooms (HAB). These anthropogenic effects destabilize ecosystems, and some HABs can pose direct human health risk. Bioretention, or the storage and controlled discharge of stormwater run-off in an ecologically engineered setting, is a potential solution to this problem. However, it relies heavily on the settling of particles as a nutrient removal mechanism, and thus struggles with pollutants, such as dissolved nitrogen, which is a particular problem in Florida where the geological prominence of phosphorus leaves nitrogen …

A Metaphysics Of The Moral Imagination: John Ruskin's Realism, Revisited, Jesse Goodman

Graduate Student Research Symposium

The Victorian philosopher John Ruskin is primarily remembered for his political writing, as a forerunner of what we would today call Christian Socialist politics. In aesthetic circles, he is also often considered something of a punchline: a stuffy conservative who represents the worst vagaries of his day, an enemy of abstraction. Ruskin thus has a double-being in cultural memory: both an admired social reformer and a laughingstock art critic.

These views of Ruskin can be potentially reconciled by showing how his critics have misunderstood his aesthetic philosophy. Ruskin is often described as an aesthetic realist, the view on which art …

Automated Seizure Detection Based On State-Space Model Identification, Zhuo Wang, Michael Sperling, Dale Wyeth, Allon Guez

Department of Neuroscience Faculty Papers

In this study, we developed a machine learning model for automated seizure detection using system identification techniques on EEG recordings. System identification builds mathematical models from a time series signal and uses a small number of parameters to represent the entirety of time domain signal epochs. Such parameters were used as features for the classifiers in our study. We analyzed 69 seizure and 55 non-seizure recordings and an additional 10 continuous recordings from Thomas Jefferson University Hospital, alongside a larger dataset from the CHB-MIT database. By dividing EEGs into epochs (1 s, 2 s, 5 s, and 10 s) and …

A Soft Competition Among Arbitral Institutions: The Institutional Oligopoly Of Mixed Arbitration, Lukas Schaugg

PhD Dissertations

Arbitral institutions play a vital role beyond merely facilitating international arbitration between private parties and states; they actively shape international legal norms and influence global governance. Despite their strategic and policy-shaping role, scholarship on arbitral institutions remains limited mostly to doctrinal analyses of their procedural functions. Addressing this gap, this thesis presents a comparative case study, exploring the influence of four dominant arbitral institutions and their leading experts on the development and evolution of mixed arbitration. The study combines insider research and work in the archives of inter- and non-governmental organizations, states, and influential individuals. It also draws on numerous …

Automatic Active Lesion Tracking In Multiple Sclerosis Using Unsupervised Machine Learning, Jason Uwaeze, Ponnada A Narayana, Arash Kamali, Vladimir Braverman, Michael A Jacobs, Alireza Akhbardeh

Faculty, Staff and Student Publications

Background: Identifying active lesions in magnetic resonance imaging (MRI) is crucial for the diagnosis and treatment planning of multiple sclerosis (MS). Active lesions on MRI are identified following the administration of Gadolinium-based contrast agents (GBCAs). However, recent studies have reported that repeated administration of GBCA results in the accumulation of Gd in tissues. In addition, GBCA administration increases health care costs. Thus, reducing or eliminating GBCA administration for active lesion detection is important for improved patient safety and reduced healthcare costs. Current state-of-the-art methods for identifying active lesions in brain MRI without GBCA administration utilize data-intensive deep learning methods.

Natural Sciences and Mathematics | Faculty Scholarship

Environmentally persistent free radicals (EPFRs), a group of emerging pollutants, have significantly longer lifetimes than typical free radicals. EPFRs form by the adsorption of organic precursors on a transition metal oxide (TMO) surface involving electron charge transfer between the organic and TMO. In this paper, dihalogenated benzenes were incorporated to study the role of electronegativity in the electron transfer process to obtain a fundamental knowledge of EPFR formation mechanism on ZnO. Upon chemisorption on ZnO nanoparticles at 250 °C, electron paramagnetic resonance (EPR) confirms the formation of oxygen adjacent carbon-centered organic free radicals with concentrations between 1016 and 1017 spins/g. …
