Study On New Reactivity Of Vinyl Gold And Its Sequential Transformations, Teng Yuan

USF Tampa Graduate Theses and Dissertations

This dissertation mainly contains three parts: 1) the study of new reactivity of vinyl gold(I) and synergistic gold-iron catalyzed regioselective crossed aldol reaction. 2) synergistic gold-iron catalyzed amide crossed aldol reaction by using ynamides as ‘masked’ amides. 3) alkyne trifunctionalization via divergent gold catalysis: combining three modes of gold catalysis: π activation, nucleophilic addition of vinyl gold and gold redox catalysis. This novel method affords access to constructing C-N, C-O and C-C bond in one step at mild condition.

In the first part, a new reaction mode in gold catalysis will be introduced. Due to the protodeauration of vinyl gold …

Ocean Quahog (Arctica Islandica) Population Dynamics: Sex-Based Demographics And Regional Comparisons In The Northwest Atlantic, Kathleen M. Hemeon

Dissertations

Arctica islandica (ocean quahog) is the longest-lived bivalve on Earth. Individuals on the deep continental shelf of the Mid-Atlantic (US) can survive for centuries, and when found in the colder, boreal waters of Iceland, ages over 500 years can be reached. The ocean quahog is important in the US, yet very little is known about the resiliency of the ocean quahog stock to fishing activity, and ocean quahog recruitment patterns over time. To quantify and constrain age-reader error prior to age analysis, a triple-method error protocol was developed for A. islandica that included age-reader bias, precision, and error frequency. The …

Hydrogen Flooding Of A Coal Core: Effect On Coal Swelling, Stefan Iglauer, Hamed Akhondzadeh, Hussein Abid, Adriana Paluszny, Alireza Keshavarz, Muhammad Ali, Ausama Giwelli, Lionel Esteban, Joel Sarout, Maxim Lebedev

Research outputs 2022 to 2026

Hydrogen is a clean fuel which has the potential to drastically decarbonize the energy supply chain. However, hydrogen storage is currently a key challenge; one solution to this problem is hydrogen geo-storage, with which very large quantities of H2 can be stored economically. Possible target formations are deep coal seams, and coal permeability is a key parameter which determines how fast H2 can be injected and withdrawn again. However, it is well known that gas injection into coal can lead to coal swelling, which drastically reduces permeability. We thus injected H2 gas into a coal core and measured dynamic permeability, …

Genome-Wide Association Studies Of Metabolites In Finnish Men Identify Disease-Relevant Loci, Xianyong Yin, Adam E Locke, Erica Young, Liron Ganel, Indraniel Das, Haley Abel, Nathan O Stitziel, Et Al

Open Access Publications

Few studies have explored the impact of rare variants (minor allele frequency < 1%) on highly heritable plasma metabolites identified in metabolomic screens. The Finnish population provides an ideal opportunity for such explorations, given the multiple bottlenecks and expansions that have shaped its history, and the enrichment for many otherwise rare alleles that has resulted. Here, we report genetic associations for 1391 plasma metabolites in 6136 men from the late-settlement region of Finland. We identify 303 novel association signals, more than one third at variants rare or enriched in Finns. Many of these signals identify genes not previously implicated in metabolite genome-wide association studies and suggest mechanisms for diseases and disease-related traits.

Small-Molecule Ras Inhibitors As Anticancer Agents: Discovery, Development, And Mechanistic Studies, Shaila A. Shetu, Debasish Bandyopadhyay

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Chemistry)

Mutations of RAS oncogenes are responsible for about 30% of all human cancer types, including pancreatic, lung, and colorectal cancers. While KRAS1 is a pseudogene, mutation of KRAS2 (commonly known as KRAS oncogene) is directly or indirectly associated with human cancers. Among the RAS family, KRAS is the most abundant oncogene related to uncontrolled cellular proliferation to generate solid tumors in many types of cancer such as pancreatic carcinoma (over 80%), colon carcinoma (40–50%), lung carcinoma (30–50%), and other types of cancer. Once described as ‘undruggable’, RAS proteins have become ‘druggable’, at least to a certain extent, due to the …

A Comparison Of Natural, Living, And Hardened Shorelines Ability To Prevent Coastal Erosion And Maintain A Healthy Ecosystem, Gabrielle Spellmann

Master's Theses

It is important to find a suitable method to protect the U.S. Gulf Coast shoreline, since its’ low elevation and the Loop current make it vulnerable to sea level rise. I focused on two manmade methods, hardened, and living shorelines, of coastal protection for when the natural marsh suffers excess erosion rates. Living shorelines are a suite of shoreline conservation and restoration techniques that usually involve some sort of hardened structure that dampens wave energy so that the native vegetation behind it can take root and stabilize the shoreline. This study looked at six different sites, all containing a natural, …

Agency, Benevolence And Justice, Prithvijit Mukherjee, J. Dustin Tracy

ESI Working Papers

We test for social norms regarding how Agents should select between risky prospects for Principals, including norms consistent with observations by Adam Smith. We elicit norms from subjects serving as ``impartial spectator[s]" about the choice of risky prospects selected by the Agents. We find strong evidence for the existence of norms, consistent with Smith's observations. Furthermore, we find that Agents are more likely to select more normative options. In contrast, we find that Principals' allocation for bonuses depends on the realization of the risky prospect rather than whether the Agents' choice was consistent with the norm.

High-frequency accelerometer recording of key predatory behaviors in vipers: validation and case study with Timber Rattlesnakes (Crotalus horridus)

Morgan Thompson, Richard H. Adams, Anna F. Tipton, and Dominic L. DeSantis

Tri-axial accelerometers (ACTs) are becoming increasingly common in studies of animal behavior wherein direct observation of subjects in nature is constrained or impossible. ACTs are small (< 1 g) piezo-electric (spring-like) sensors that measure three-dimensional acceleration (upward, downward, and side-to-side) derived from subject motion. When leveraged with advanced machine learning techniques, these data can enable precise automated classification of a wide range of movement-mediated behaviors. Until recently, ACTs were largely reserved for larger-bodied organisms or those most amenable to the temporary external attachment of devices. Ongoing ACT miniaturization has now expanded the breadth of organisms amenable to these methods. This project aims to expand on a recently developed framework for ACT monitoring in wild-ranging snakes, a group that has been mostly overlooked in biologging applications. We are currently conducting extensive captive validation trials for robust model training and testing to enable classification of predatory behaviors, including striking and ingestion of prey items, in Timber Rattlesnakes (Crotalus horridus). Following captive validation, we will translate this method to the field with a population of C. horridus in the lower Piedmont of middle Georgia to evaluate the efficacy of externally attached ACTs for remote and continuous monitoring of …

The Method Of Critical Phenomenology: Simone De Beauvoir As A Phenomenologist., Johanna K. Oksala

Philosophy: Faculty Publications and Other Works

The paper aims to contribute to the ongoing conversation on critical phenomenology with reflections on its method. The key argument is that critical phenomenology should be understood as a form of historico-transcendental inquiry and therefore it cannot forgo the phenomenological reduction. Rather, this methodological step should be centered in critical phenomenology, and appropriated in problematized and rethought forms. The methodological assessment of critical phenomenology has implications also for how we read its canon. The paper shows that while Simone de Beauvoir did not adopt the phenomenological reduction in its full Husserlian meaning, her analyses of experience did not remain on …

A Global Soil Spectral Calibration Library And Estimation Service, Keith D. Sheperd, Rich Ferguson, David Hoover, Fenny Van Egmond, Jonathan Sanderman, Yufeng Ge

Department of Agronomy and Horticulture: Faculty Publications

There is growing global interest in the potential for soil reflectance spectroscopy to fill an urgent need for more data on soil properties for improved decision-making on soil security at local to global scales. This is driven by the capability of soil spectroscopy to estimate a wide range of soil properties from a rapid, inexpensive, and highly reproducible measurement using only light. However, several obstacles are preventing wider adoption of soil spectroscopy. The biggest obstacles are the large variation in the soil analytical methods and operating procedures used in different laboratories, poor reproducibility of analyses within and amongst laboratories and …

Phenotypic Variability In Ipsc-Induced Cardiomyocytes And Cardiac Fibroblasts Carrying Diverse Lmna Mutations, Jiajia Yang

USF Tampa Graduate Theses and Dissertations

Mutations in the LMNA gene (encoding lamin A/C) are the second most common cause of familial arrhythmogenic cardiomyopathy. Diverse LMNA variants in cardiomyocytes have been associated with cardiac phenotypes. Moreover, cardiac fibroblasts make up a large fraction of the myocardium's non-myocyte component, intrinsically linked to extracellular matrix synthesis and turnover as well as secreting large amounts of bioactive metabolites. However, our understanding of how different mutation sites and the non-myocyte niche mediate cardiomyocyte function is limited. To fill this gap, in this thesis I investigated the hypothesis that variable LMNA mutations have significant effects on the genetic, structure and electrophysiological …
