Holding States Accountable For Harmful Algal Blooms: Florida's Water Crisis In Focus, Jason Totoiu, Jaclyn Lopez

University of Florida Journal of Law & Public Policy

Scientists generally agree that agricultural runoff is a principal source of nutrient pollution in the United States. Intensive agricultural practices have resulted in decades of phosphorus and nitrogen accumulating in the natural system which continue to contribute substantially to nutrients entering watersheds. Coupled with failed water quality control measures, this water pollution has led to some of the worst harmful algal blooms (HABs) in recorded history. These nonpoint sources need to be addressed to restore and protect water quality.

Florida’s Lake Okeechobee watershed provides an apt case study. Commonly referred to as the “liquid heart” of the Everglades, the lake …

Substrate Stiffness Modulates Migration And Local Intercellular Membrane Motion In Pulmonary Endothelial Cell Monolayers, Sunita Subedi Paudel, Althea Deweever, Sarah Sayner, Troy Stevens, Dhananjay T. Tambe

University Faculty and Staff Publications

The pulmonary artery endothelium forms a semipermeable barrier that limits macromolecular flux through intercellular junctions. This barrier is maintained by an intrinsic forward protrusion of the interacting membranes between adjacent cells. However, the dynamic interactions of these membranes have been incompletely quantified. Here, we present a novel technique to quantify the motion of the peripheral membrane of the cells, called paracellular morphological fluctuations (PMFs), and to assess the impact of substrate stiffness on PMFs. Substrate stiffness impacted large-length scale morphological changes such as cell size and motion. Cell size was larger on stiffer substrates, whereas the speed of cell movement …

Black Culture Is "Professional": Causation After Bostock & Racial Stereotypes, Adriante Carter

University of Florida Journal of Law & Public Policy

Employment discrimination has progressed past the days of overt prejudices. In today’s society, employment discrimination manifests as stereotypes that perpetuate negative results. Those who suffer from stereotypic discrimination have long been denied redress for these wrongs. The U.S. Supreme Court’s decision in Bostock, this Note argues, is a way forward. This Note argues that case law has developed, and should continue to develop, in a way that recognizes racial stereotyping as discriminatory. This Note explores the history of this case law and examines how the theory of causation from Bostock can be used to better the jurisprudence on racial …

Low-Cost Compact Optical Spectroscopy And Novel Spectroscopic Algorithm For Point-Of-Care Real-Time Monitoring Of Nanoparticle Delivery In Biological Tissue Models, Zahid Hasan, Jing Yan, Zhongchao Yi, Madison O. Korfhage, Sheng Tong, Caigang Zhu

Markey Cancer Center Faculty Publications

Objective: Real-time monitoring of nanoparticle delivery in biological models is essential to optimize nanoparticle- mediated therapies. However, few techniques are available for convenient real-time monitoring of nanoparticle concentrations in tissue samples. This work reported novel optical spectroscopic approaches for low-cost point-of-care real-time quantification of nanoparticle concentrations in biological tissue samples.

Methods: Fiber probe measured diffuse reflectance can be described with a simple analytical model by introducing an explicit dependence on the reduced scattering coefficient. Relying on this, the changes on the inverse of diffuse reflectance are proportional to absorption change when the scattering perturbation is negligible. We developed this model …

Tnf-Α And Nf-Κb Signaling Play A Critical Role In Cigarette Smoke-Induced Epithelial-Mesenchymal Transition Of Retinal Pigment Epithelial Cells In Proliferative Vitreoretinopathy, Victor Wang, Alison Heffer, Elisa Roztocil, Steven E Feldon, Richard T Libby, Collynn F Woeller, Ajay E Kuriyan

Wills Eye Hospital Papers

Proliferative vitreoretinopathy (PVR) is characterized by the growth and contraction of cellular membranes within the vitreous cavity and on both surfaces of the retina, resulting in recurrent retinal detachments and poor visual outcomes. Proinflammatory cytokines like tumor necrosis factor alpha (TNFα) have been associated with PVR and the epithelial-mesenchymal transition (EMT) of retinal pigment epithelial (RPE) cells. Cigarette smoke is the only known modifiable risk factor for PVR, but the mechanisms are unclear. The purpose of this study was to examine the impact of cigarette smoke on the proinflammatory TNFα/NF-κB/Snail pathway in RPE cells to better understand the mechanisms through …

Dissertations and Theses Collection (Open Access)

Traceability is the first step to gain visibility in the supply chain and can be used to meet different purposes. Similar to other agriculture crops, the natural rubber industry faces reputational damage due to deforestation, land grab, loss of biodiversity and non-compliance with environmental standards occurring in the upstream. The introduction of new social and environmental regulations accelerates the need for traceability. Reflecting on the importance of environmental and social considerations, this industry is looking at traceability to identify the historical trends leading to the present sustainability state and any ongoing sustainability risks in the upstream to enable downstream users …

Islamist Homophobia In The West: From Rhetoric To Violence, Lorenzo Vidino, Alexander Meleagrou-Hitchens, Program On Extremism, George Washington University, National Counterterrorism Innovation, Technology, And Education Center

Reports, Projects, and Research

The global LGBTQIA+ (lesbian, gay, bisexual, transgender, queer/questioning, intersex and asexual/aromantic/agender) community has historically been subjected to hateful rhetoric, discriminatory practices and acts of violence. In the West, this animosity has traditionally mostly originated from a heterogeneous array of actors that can broadly be identified with the far-right. And while in recent years the LBGTQIA+ community has received rights and a degree of acceptance largely unthinkable only a few decades ago, episodes of intolerance and violence are still very much present. Recently, for example, in June 2022, authorities detained 31 members of a white nationalist group called Patriot Front who …

The Islamic State In America: After The Caliphate, Lorenzo Vidino, Seamus Hughes, Bennett Clifford, Program On Extremism, George Washington University, National Counterterrorism Innovation, Technology, And Education Center

Reports, Projects, and Research

The time period in which the Islamic State (IS) controlled territory in Syria and Iraq between 2014 and 2019 coincided with the largest groundswell of homegrown jihadist activity in United States history. This unprecedented wave of jihadist activism, which hit its peak between 2014 and 2016, could be measured through several indicators. Senior officials in the Federal Bureau of Investigation (FBI) testified that the Bureau managed, at any given time between 2014 and 2019, 1,000 active investigations into IS supporters throughout the U.S.; at least 239 alleged supporters were charged in U.S. courts. Meanwhile, more than 80 Americans traveled to …

An Integrated Approach For Controlling Verticillium Wilt Of Strawberry, Jack T. Koster

Master's Theses

Strawberry (Fragaria x ananassa, Duch.) is an important crop in California, with more than 35,000 acres planted in 2018 resulting in a farm gate value of $3.1 billion. In 2020, California strawberry production accounted for more than 85% of national strawberry production and faces serious threats to production due to various soil-borne diseases. One such disease, Verticillium wilt, is caused by the fungal pathogen Verticillium dahliae and is commonly found in temperate zones around the world where strawberries are grown. Due to the phase-out of efficacious fumigants like methyl bromide, alternative disease management methods have become necessary to …

Analysis Of Current And Future Flood Hazard In The Sacramento-San Joaquin Delta, Nicholas L. Mcguire

Master's Theses

The primary motivation of this study is to estimate the current and future flood hazard throughout the Sacramento-San Joaquin Delta in the context of sea-level rise. I also analyzed the effects of storm surge and river flow on extreme events to better understand how these events originate and vary spatially and in time. To address this goal, I combined digital water level records (primarily 1983-present) with archival data collected by the California Department of Water Resources (1929-1983) to reevaluate flood hazard in the Delta and investigate the possible sensitivity of the region different sea-level rise projections. Available archival records from …

Determination Of Fungicide Resistance In Botrytis Cinerea On Wine Grapes In California's Central Coast Region, Evelyn Alvarez-Mendoza

Master's Theses

Botrytis bunch rot, caused by Botrytis cinerea, is a fungal disease that primarily affects the fruit of wine grapes. Infection of fruit consequently results in reduced yields and wine quality. These factors lead to significant economic losses for growers which prompts the implementation of management practices to control the disease. One objective of this study was to evaluate the level of resistance that populations of B. cinerea in the Central Coast region showed to various chemicals. A fungicide assay was conducted to determine resistant phenotypes to six fungicide active ingredients (pyrimethanil, iprodione, fenhexamid, fludioxonil, trifloxystrobin, boscalid). Thirty-five (2020) and …

A Qualitative Descriptive Study On Re-Assessing The Mental Certification By Faa For Future Pilots, Kaung Z. Min

Student Works

Mental illness becomes one of the main problems that most pilots do not usually address. It is not because pilots do not have the courage or are open enough to talk with someone, but because the Federal Aviation Administration (FAA) forces them to hide from mental depression. Most of the time, the pilots are not willing to declare such illnesses as they fear losing their job; simultaneously, the Federal Aviation Agencies across the world require pilots to be in peat health, including their mental condition, to operate the aircraft. While it can be said that the passengers’ and crews’ safety …

Modal Analysis For Single-Mode Waveguides Of Silicon On Sapphire (Sos) At Infrared Region Using Finite Element Method (Fem), Yadgar Shwan

Journal of Applied Sciences and Nanotechnology

One of the recommended platforms for waveguide generation in the infrared region is silicon-on-sapphire (SOS). This paper proposes a modal of the optical waveguide of silicon on a sapphire from  ), using FEM (finite-element method) solver simulation performed by FDTD [finite-different-time-domain]. The waveguide is directly based on the refractive index difference between the wave's guideline regions and surrounding media (cladding). The use of FEM to analyze a single waveguide mode of SOS at a certain size within multiple wavelengths is a unique aspect of this research. In addition, this project's objective is to discov how the waveguide size (dimension) impacts …
