Dissolved Nickel Speciation At The Bermuda Atlantic Time-Series Study (Bats) Site, Caitlyn E. Parente

USF Tampa Graduate Theses and Dissertations

Here I present the first depth profiles of dissolved nickel (DNi) speciation over an annual cycle at the Bermuda Atlantic Time-series Study (BATS) site in the North Atlantic. Seawater samples were collected in March, May, August, and November 2019 and analyzed for labile DNi using competitive ligand exchange-adsorptive cathodic stripping voltammetry (CLE-AdCSV). Labile DNi was measured by CLE-AdCSV as the fraction of DNi that exchanges with an added competitive ligand in an overnight equilibration. Results revealed two distinct fractions of DNi present throughout the water column: a labile fraction, and a strongly organically complexed (i.e., non-labile) fraction. More than 50% …

Drought Legacy Interacts With Wildfire To Alter Soil Microbial Communities In A Mediterranean Climate-Type Forest, Anna J. M. Hopkins, Aaron J. Brace, Jess L. Bruce, J. Hyde, J. B. Fontaine, L. Walden, W. Veber, K. X. Ruthrof

Research outputs 2022 to 2026

Mediterranean forest ecosystems will be increasingly affected by hotter drought and more frequent and severe wildfire events in the future. However, little is known about the longer-term responses of these forests to multiple disturbances and the forests' capacity to maintain ecosystem function. This is particularly so for below-ground organisms, which have received less attention than those above-ground, despite their essential contributions to forest function. We investigated rhizosphere microbial communities in a resprouting Eucalyptus marginata forest, southwestern Australia, that had experienced a severe wildfire four years previously, and a hotter drought eight years previously. Our aim was to understand how microbial …

The Myth Of Tightening Credit Rating Standards In The Market For Corporate Debt, Karolina Krystyniak, Viktoriya Staneva

Faculty Publications

This study revisits the existing evidence of a downward trend in credit rating standards indicating that CRAs have become more conservative over time. We find that the time-series variation in the proxy for rating standards is mostly driven by the market-based variables in the model, specifically market capitalization and idiosyncratic volatility. We examine an alternative specification of the model, incorporating risk characteristics of rated firms relative to those of the average firm in the economy, and find it to have a higher explanatory power. Most importantly, we find little evidence of increased conservatism over time, in contrast to prior studies.

A Hybrid Control Approach For A Pneumatic-Actuated Soft Robot, Emilio Tavio Y Cabrera, Cosimo Della Santina, Pablo Borja

School of Engineering, Computing and Mathematics

The compliant nature of soft robots is appealing to a wide range of applications. However, this compliant property also poses several control challenges, e.g., how to deal with infinite degrees of freedom and highly nonlinear behaviors. This paper proposes a hybrid controller for a pneumatic-actuated soft robot. To this end, a model-based feedforward controller is designed and combined with a correction torque calculated via Gaussian process regression. Then, the proposed model-based and hybrid controllers are experimentally validated, and a detailed comparison between controllers is presented. Notably, the experimental results highlight the potential benefits of adding a learning approach to a …

Do Patents Drive Investment In Software?, James Hicks

Northwestern University Law Review

In the wake of a quartet of Supreme Court decisions which disrupted decades of settled law, the doctrine of patentable subject matter is in turmoil. Scholars, commentators, and jurists continue to disagree sharply over which kinds of invention should be patentable. In this debate, no technology has been more controversial than software. Advocates of software patents contend that denying protection would stymie innovation in a vital industry; skeptics argue that patents are a poor fit for software, and that the social costs of patents outweigh any plausible benefits. At the core of this disagreement is a basic problem: the debate …

Difficulties Of Hydrofracturing In Sandstone – Experimental Study, S Vikram, Dheeraj Kumar, Ds Subrahmanyam

Journal of Sustainable Mining

Hydrofracturing in sandstone is not an easy task. Sandstone is porous; fluid dissipation is common hence unable to obtain breakdown pressures in certain flow rates (0.0000005–0.0001 m3/s). The higher flow rate (0.00025 m3/s) is ascertained to determine the fracturing pressures. Due to this, fracture propagation and delineation are observed [1]. To enhance, an experimental method is adopted by carrying out 6 Hydrofracturing tests in a borehole comprising sandstone. A high flow rate of 0.00025 m3/s and viscosity 0.001 Pascal second is applied. Later, the fracture simulation was run on 12 core samples collected from the same depths in a lab. …

Bacteriophage Therapy For The Treatment Of Mycobacterium Tuberculosis Infections In Humanized Mice, Fan Yang, Alireza Labani-Motlagh, Jose Alejandro Bohorquez, Josimar Dornelas Moreira, And Additional Authors

School of Medicine Faculty Publications and Presentations

The continuing emergence of new strains of antibiotic-resistant bacteria has renewed interest in phage therapy, however, there has been limited progress in applying phage therapy to multi-drug resistant Mycobacterium tuberculosis (Mtb) infections. In this study, we show that bacteriophage strains D29 and DS6A can efficiently lyse Mtb H37Rv in 7H10 agar plates. However, only phage DS6A efficiently kills H37Rv in liquid culture and in Mtb-infected human primary macrophages. We further show in subsequent experiments that, after the humanized mice were infected with aerosolized H37Rv, then treated with DS6A intravenously, the DS6A treated mice showed increased body weight and improved pulmonary …

A Heuristic Approach To Solving Complex Litigation Problems, Melanie L. Oxhorn

University of Cincinnati Law Review

This Article’s purpose is to propose a heuristic for effectively resolving complex litigation problems that are not clearly or concisely defined, do not present any immediate solutions, frequently involve novel situations or applications of legal doctrine, and suggest a var­­­­iety of possible approaches. The features of this heuristic are derived from and compatible with what we know about good scientific theories and cognitive studies on acquiring knowledge and expertise in any area. As proposed herein, students and less experienced practitioners should focus on developing “critical thinking” skills allowing them to use their training and experience to become adept at identifying …

Stem Course Taking Patterns Of Transferred Students From Tribal College, Shurong Li

UM Graduate Student Research Conference (GradCon)

Montana largest race/ethnic non-While population is Native Americans (NAs) - 8.2% of the population compared to 1.7% nationally (American Community Survey 2017; U.S. Census Bureau, 2015). Montana, known for its expansive Native American reservation territories, is also home to a significant number of tribal colleges.

While tribal colleges and universities (TCUs) play a crucial role in preserving cultural heritage and fostering academic growth, Native American students face distinctive challenges when they graduate from a TCU and transfer to a 4-year institution outside their reservations. These challenges include maintaining a sense of community connection, encountering a lack of cultural competence in …

Prdm3 Protein Purification: An Optimized Approach For Structural Understanding, Ifeoluwa A. Dada

UM Graduate Student Research Conference (GradCon)

Investigating proteins involved in driving cancer progression is crucial for advancing therapeutic strategies. PRDM3 (PR/SET domain-containing 3) has emerged as a key player in sustaining ovarian tumors. To facilitate an in-depth study of PRDM3, obtaining the protein in substantial quantities with a high-level purity through recombinant expression is imperative.

The methodology comprises a series of steps: integrating the PRDM3 gene fused with an affinity tag into a plasmid; transferring the engineered plasmid into bacterial cells; expressing the affinity-tagged protein (fusion protein) within the bacterial cells and harvesting them. Cell lysis and protein extraction are then conducted, followed by affinity chromatography …

Landscape Influences On Microclimate And Tree Growth Cessation In A Semi-Arid Montane Forest, Fin Malone, Kelsey G. Jencso, Zachary H. Hoylman

UM Graduate Student Research Conference (GradCon)

As climate change impacts the severity and frequency of drought, knowledge of hillslope-to-watershed scale ecohydrology is becoming increasingly necessary to inform appropriate conservation, restoration, and management of forested ecosystems. In mountain environments, spatial patterns of water and energy organize forest productivity at plot, hillslope, and watershed scales. These microclimatic patterns are impacted by gradients in elevation, aspect, and local topographic convergence and divergence. In water-limited systems, such patterns of moisture may be first-order drivers of intra-annual tree growth. However, there is limited field-based research characterizing how seasonal limitations of forest growth may vary across complex terrain. In 2016, continuous soil …
