Effect Of Solitary And Combined Use Of Cover Crops On Soilborne Disease Suppressiveness In Woody Ornamental Nursery Production Systems, Madhav Parajuli, Fulya Baysal-Gurel, Milan Panth

Student Research

Cover crops are known to be effective in reducing soilborne diseases in woody ornamentals. However, it remains unknown how solitary and combined uses of cover crops influence soilborne disease, and whether these effects differ with seed rate. The objective of this study was to explore the impacts of cover crops, in solitary and combined use, on soilborne disease suppressiveness in woody ornamental nursery production systems. Soils were sampled from the established red maple (Acer rubrum L.) plantation grown with and without cover crops [crimson clover (Trifolium incarnatum L.)] or triticale (× Triticosecale W.) or (their mixture)] following the cover crop …

Materials Science And Mechanosensitivity Of Living Matter, Alison E. Patteson, Merrill E. Asp, Paul A. Janmey

Physics - All Scholarship

Living systems are composed of molecules that are synthesized by cells that use energy sources within their surroundings to create fascinating materials that have mechanical properties optimized for their biological function. Their functionality is a ubiquitous aspect of our lives. We use wood to construct furniture, bacterial colonies to modify the texture of dairy products and other foods, intestines as violin strings, bladders in bagpipes, and so on. The mechanical properties of these biological materials differ from those of other simpler synthetic elastomers, glasses, and crystals. Reproducing their mechanical properties synthetically or from first principles is still often unattainable. The …

Monospecific And Bispecific Monoclonal Sars-Cov-2 Neutralizing Antibodies That Maintain Potency Against B.1.617, Lei Peng, Yingxia Hu, Madeleine C Mankowski, Ping Ren, Rita E Chen, Michael S Diamond, Et Al

Open Access Publications

COVID-19 pathogen SARS-CoV-2 has infected hundreds of millions and caused over 5 million deaths to date. Although multiple vaccines are available, breakthrough infections occur especially by emerging variants. Effective therapeutic options such as monoclonal antibodies (mAbs) are still critical. Here, we report the development, cryo-EM structures, and functional analyses of mAbs that potently neutralize SARS-CoV-2 variants of concern. By high-throughput single cell sequencing of B cells from spike receptor binding domain (RBD) immunized animals, we identify two highly potent SARS-CoV-2 neutralizing mAb clones that have single-digit nanomolar affinity and low-picomolar avidity, and generate a bispecific antibody. Lead antibodies show strong …

Organizational Silofication: Implications In Grouping Experts For Organizational Performance, Dave Silberman, Rob E. Carpenter, Elena Cabrera, Jasmine Kernaleguen

Human Resource Development Faculty Publications and Presentations

This paper offers that organizational underachievement sourced to workplace expertise is a product of bounded perspective constructed by the agency of expertise. Embedded in any bounded perspective is limitations to what can be seen. Organizations that seek to leverage expertise solely on their agency risk organizational silofication. We conclude that recognizing organizational silofication is an opportunity for organizations to address organizational underachievement by addressing the perspectives that create the hidden impediments limiting their overall potential.

Walla, Shi-Hui Dong, Xiaoyu Tang, Hexin Chen, Prakash Nagarkatti, Mitzi Nagarkatti, Yong-Xin Li, Jie Li

Faculty Publications

Bacterial natural product biosynthetic genes, canonically clustered, have been increasingly found to rely on hidden enzymes encoded elsewhere in the genome for completion of biosynthesis. The study and application of lanthipeptides are frequently hindered by unclustered protease genes required for final maturation. Here, we establish a global correlation network bridging the gap between lanthipeptide precursors and hidden proteases. Applying our analysis to 161,954 bacterial genomes, we establish 5209 correlations between precursors and hidden proteases, with 91 prioritized. We use network predictions and co-expression analysis to reveal a previously missing protease for the maturation of class I lanthipeptide paenilan. We further …

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, …

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, …

Geothermal Development In Kenya: Gender Based Socio-Cultural And Socio-Economic Implications, Faye N. Ricker

USF Tampa Graduate Theses and Dissertations

This dissertation is an ethnographic case study that analyzes the gendered socio-cultural and socio-economic implications for a community that was displaced in order to develop a geothermal energy system in Kenya. The implications are rendered particularly interesting because the displaced community is also one of the communities served by the geothermal power grid. The analysis employs a composite framework of Feminist Political Ecology and the Political Ecology of Climate Change Mitigation. This work explores gendered perceptions and control of energy, livelihood activities, place attachment, and the cultural/spiritual significance of geothermal energy.

Geothermal energy is a potentially promising source of low-carbon …

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 …

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.

The Mitigation Of In-Group And Outgroup Biases: Understanding The Perceptions Of Educators On The Contact Approach Theory, Brigitte Blazys

Dissertations

The contact approach theory was introduced in the 1950s, by Allport, as a method to mitigate biases. Since then, many DEI practitioners in the United States have formed alliances to create a social justice movement to combat racism, prejudice, and biases in our society. Nevertheless, little research has been conducted in the contact approach theory as these biases, initially observed as in-group and outgroup biases, originate in the early years of life. To begin to fill this gap in the literature, the purpose of this study was to better understand and identify to what extent, if any, prekindergarten through third …

The Effects Of Career Commitment, Distress, And Persistence On Academic Success Among Undergraduate Baccalaureate Nursing Students, Kimberly D. Kennel

Dissertations

The ability of students, specifically in higher education environments, to persist is a critical determinant of academic success. Student success is especially precarious within programs of nursing, where curricula include clinical, laboratory, and didactic content. Identifying and describing the barriers and facilitators to nursing student persistence provides a blueprint to appropriately use financial and human resources as well as determine the effect student demographic variables has on desiring, attending, or benefiting from persistence interventions. The outcome of this study can guide the deployment of institutional resources to provide persistence-based interventions that are evidence-based. Framed by Tinto's Theory of Student Departure, …

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.

Seabem: An Artificial Intelligence Powered Web Application To Predict Cover Crop Biomass, Aime Christian Tuyishime, Andrea Basche

Honors Program: Senior Projects (Public)

SEABEM, the Stacked Ensemble Algorithms Biomass Estimator Model, is a web application with a stacked ensemble of Machine Learning (ML) algorithms running on the backend to predict cover crop biomass for locations in Sub-Saharan. The SEABEM model was developed using a previously developed database of crop growth and yield that included site characteristics such as latitude, longitude, soil texture (sand, silt, and clay percentages), temperature, and precipitation. The goal of SEABEM is to provide global farmers, mainly small-scale African farmers, the knowledge they need before practicing and benefiting from cover crops while avoiding the expensive and time-consuming operations that come …

Advanced Directives And Pregnancy: A Comparison Between The Us And Ireland, Simone Shuman

Cardozo International & Comparative Law Review (CICLR) Blog

Advance directives enable patients to specify which medical treatment they do and do not want to receive ahead of time if they cannot make such a determination, including the refusal or ending of life support when the time to act on such a decision arises. There are two types of advance directives: (1) living wills where a patient lists their treatment preferences and (2) creating a health care power of attorney which vests the decision-making authority in a proxy. Since the creation of advance directives in 1976, all fifty states have adopted their own laws on advance directives.

Depression is one of the biggest health issues among men who have sex with men (MSM) living with HIV, where sexual identity might play an intricate role. Yet, findings of the relationship between sexual identity and depression were mixed and few studies explored its underlying mechanisms. This study aimed to examine the association between sexual identity and depression, and the potential mediating role of HIV-related stigma and moderating role of age. A cross-sectional survey was conducted among 203 MSM living with HIV in Guangxi, China. Participants provided information on sexual identity, depression, HIV-related stigma, and background information. Descriptive statistics, bivariate …

A Statistical Method For Quantifying Animal Interaction; Combining Time Geography And Simulation, Zachary J. Smith

USF Tampa Graduate Theses and Dissertations

Dynamic interaction (DI) describes the synchronous interaction of one or more individual animals over time. Current methods to quantify DI from tracking data are lacking. They typically require synchronized tracking data which limits their applicability to most studies. They also often do not have built-in tests of significance to evaluate interaction, and if so, rely on random walk models that lack biological realism. This research aimed to develop and evaluate a new way of measuring animal interaction that overcomes these limitations. The goal was to create a statistical method for quantifying and evaluating interaction that is relevant across computational, behavioural, …
