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 …

Design And Analysis Of A Discrete, Pcb-Level Low-Power, Microwave Cross-Coupled Differential Lc Voltage-Controlled Oscillator, Pavin Singh Virdee

Master's Theses

Radio Frequency (RF) and Microwave devices are typically implemented in Integrated Circuit (IC) form to minimize parasitics, increase precision and tolerances, and minimize size. Although IC fabrication for students and independent engineers is cost-prohibitive, an abundance of low-cost, easily accessible printed circuit board (PCB) and electronic component manufacturers allows affordable PCB fabrication.

While nearly all microwave voltage-controlled oscillator (VCO) designs are IC-based, this study presents a discrete PCB-level cross-coupled, differential LC VCO to demonstrate this more affordable and accessible approach. This thesis presents a 65 mW, discrete component VCO PCB with industry-comparable RF performance. A phase noise of -103.7 dBc/Hz …

Cofermentation, Post-Alcoholic, And Post-Malolactic Fermentation Blending Of Malbec, Merlot And Petite Sirah Wines, Armando Arturo Vega-Osorno

Master's Theses

A two-year study was conducted to assess the effects of cofermentation on red wine varietals. During the winemaking process, wines can be made from two or more varieties by picking, crushing and fermenting them together, a practice known as cofermentation. They can also be blended either after the completion of alcoholic fermentation or after malolactic fermentation. In the first year of the study, two grape varieties, Merlot (Mer), and Malbec (Mal) were cofermented. On the second year, a third varietal, Petite Sirah (PS) was also studied. Cofermented wines containing every possible binomial combination of the varietals was made and one …

Hydrologic Response Of Little Creek To The 2020 Czu Lightning Complex Fire At The Swanton Pacific Ranch, Kylie E. Dupuis

In this study, stage, streamflow, and precipitation data was collected from small watersheds in the Swanton Pacific Ranch for the first two hydrologic years following the 2020 CZU Lightning Complex. The Little Creek watershed was setup for high-resolution data collection with four separate stage gauge sites (Main Stem, North Fork, South Fork, and Upper North Fork) and four rain gauge sites (Al Smith House, Ridgeline, Upper North Fork, and Landing 23). Stage gauge sites were also established at Queseria, Archibald, and Mill creeks. Preliminary post-fire rating curves were developed for the four sites of Little Creek. The Main Stem (MS) …

Optimal Standards Of Proof In Antitrust, Murat C. Mungan, Joshua Wright

Faculty Scholarship

Economic analyses of antitrust institutions have thus far focused predominantly on optimal penalties and the design of substantive legal rules, and have largely ignored the standard of proof used in trials as a policy tool in shaping behavior. This neglected tool can play a unique role in the antitrust context, where a given firm may have the choice to engage in exceptional anticompetitive or procompetitive behavior, or simply follow more conventional business practices. The standard of proof used in determining the legality of a firm’s conduct affects not only whether the firm chooses to engage in pro- versus anticompetitive behavior, …

Fashion In The Times Of War: The Recent Exodus Of Luxury Brands From Russia And What It Means For Trademark Law, Irene Calboli, Vera Sevastianova

Faculty Scholarship

In February 2022, Russia infamously invaded Ukraine, starting an unprovoked war. As a result, many foreign companies left their Russia-based operations, including most luxury fashion houses. In these remarks, we elaborate on the possible issues that these companies may face regarding the enforcement of their IP rights in Russia, particularly trademark rights, following their departure resulting from the sanctions imposed by Western countries.

At the time of writing, perhaps the most pressing issue is whether luxury fashion houses risk losing their trademark rights in Russia due to their decision to suspend their operations, even though temporarily. An additional issue facing …

Amaranthus palmeri has recently evolved resistance to glufosinate herbicide. Several A. palmeri populations from Missouri and Mississippi, U.S.A. had survivors when sprayed with glufosinate-ammonium (GFA, 657 g ha⁻¹). One population, MO#2 (fourfold resistant) and its progeny (sixfold resistant), were used to study the resistance mechanism, focusing on the herbicide target glutamine synthetase (GS). We identified four GS genes in A. palmeri; three were transcribed: one coding for the plastidic protein (GS2) and two coding for cytoplasmic isoforms (GS1.1 and GS1.2). These isoforms did not contain mutations associated with resistance. The 17 glufosinate survivors …

The Economic Impact Of Buying And Redeveloping Ellis Park By Churchill Downs, Thomas E. Lambert

Faculty and Staff Scholarship

Churchill Downs’ acquisition of Ellis Park Racing and Gaming in Henderson, Kentucky reflects the growing number of mergers across the US among racetracks, racetracks and casinos, and casinos with other casinos. Some years back, Ellis racetrack closed for one year due to declining profitability, yet after new ownership took over and a gaming center was added, it began a rebound in earnings (Courier and Press 2008). The $75 million that Churchill Downs plans to spend to transform Ellis Park (Schulz 2022) will have a much bigger impact than the construction, revamping, and expansion of park facilities. This is in addition …

Context For Reproducibility And Replicability In Geospatial Unmanned Aircraft Systems, Cassandra Howe, Jason A. Tullis

Geosciences Faculty Publications and Presentations

Multiple scientific disciplines face a so-called crisis of reproducibility and replicability (R&R) in which the validity of methodologies is questioned due to an inability to confirm experimental results. Trust in information technology (IT)-intensive workflows within geographic information science (GIScience), remote sensing, and photogrammetry depends on solutions to R&R challenges affecting multiple computationally driven disciplines. To date, there have only been very limited efforts to overcome R&R-related issues in remote sensing workflows in general, let alone those tied to unmanned aircraft systems (UAS) as a disruptive technology. This review identifies key barriers to, and suggests best practices for, R&R in geospatial …

Cutaneous Manifestations Of Nutritional Deficiencies In The Context Of Food Deserts Of United States., Justin P Canakis, Shane M. Swink Do, Nicholas P Valle, Diana A. Rivers Do, Kristina M. Lim Do, Steven Oberlender Md, Phd, Stephen M. Purcell Do, Cynthia L. Bartus Md

Department of Medicine

Food deserts exist due to a multitude of factors ranging from socioeconomic status, racial disparities, geography, cost, and healthful food access. Given the vast biological function of vitamins and minerals, the clinical presentation for nutritional deficiencies ranges from benign to life-threatening. Often, the first indicators of underlying nutritional deficiencies are cutaneous manifestations. The first patient case is a 36-year-old female at 25 weeks gestation with a pruritic and painful rash that began in the genital region and spread centrifugally to her legs. The second patient case is a 42-year-old male with a pruritic rash that began at his abdomen and …

Love In The Time Of Covid, Jeanne L. Schroeder

Articles

A striking aspect of the current American cultural divide is divergent attitudes towards expertise, generally, and masking and vaccination to mitigate the Covid-19 pandemic, specifically. Liberal pundits profess shock that Red State America won’t just ‘trust the science’. On the right, politicians and television personalities reject mandates in the name of ‘freedom’.

Lacanian discourse theory gives insight into this. The rejection of expertise is an example of an ‘hysteric discourse’ challenging a ‘university discourse’: the regime of experts. An hysteric discourse is a critique of rules imposed by experts by the subjects-subjected-to them. Hysteria can lead, in turn, to a …

High-Coverage Whole-Genome Sequencing Of The Expanded 1000 Genomes Project Cohort Including 602 Trios, Marta Byrska-Bishop, Haley J Abel, Allison A Regier, Ira M Hall, Et Al.

2020-Current year OA Pubs

The 1000 Genomes Project (1kGP) is the largest fully open resource of whole-genome sequencing (WGS) data consented for public distribution without access or use restrictions. The final, phase 3 release of the 1kGP included 2,504 unrelated samples from 26 populations and was based primarily on low-coverage WGS. Here, we present a high-coverage 3,202-sample WGS 1kGP resource, which now includes 602 complete trios, sequenced to a depth of 30X using Illumina. We performed single-nucleotide variant (SNV) and short insertion and deletion (INDEL) discovery and generated a comprehensive set of structural variants (SVs) by integrating multiple analytic methods through a machine learning …

Atrial fibrillation (AF) is the most common arrhythmia in the United States, affecting approximately 1 in 10 adults, and its prevalence is expected to rise as the population ages. Treatment options for AF are limited; moreover, the development of new treatments is hindered by limited (1) knowledge regarding human atrial electrophysiological endpoints (e.g., conduction velocity [CV]) and (2) accurate experimental models. Here, we measured the CV and refractory period, and subsequently calculated the conduction wavelength, in vivo (four subjects with AF and four controls), and ex vivo (atrial slices from human hearts). Then, we created an in vitro model of …

The Nepenthesin Insert In The Plasmodium Falciparum Aspartic Protease Plasmepsin V Is Necessary For Enzyme Function, Alexander J Polino, Justin J Miller, Soumendranath Bhakat, Sumit Mukherjee, Suhas Bobba, Gregory R Bowman, Daniel E Goldberg

2020-Current year OA Pubs

Plasmepsin V (PM V) is a pepsin-like aspartic protease essential for growth of the malarial parasite Plasmodium falciparum. Previous work has shown PM V to be an endoplasmic reticulum-resident protease that processes parasite proteins destined for export into the host cell. Depletion or inhibition of the enzyme is lethal during asexual replication within red blood cells as well as during the formation of sexual stage gametocytes. The structure of the Plasmodium vivax PM V has been characterized by X-ray crystallography, revealing a canonical pepsin fold punctuated by structural features uncommon to secretory aspartic proteases; however, the function of this unique …

Relationships Between Quality Of Work-Life, Burnout And Professional Commitment Among Nurses, Siew Li Foo

Research Publications (2021 to 2025)

Professional commitment has significant influence on nurses’ job performance and patients’ outcomes. An increasingly excessive workload seems to be an inevitable consequence of the advancement in medical technology. A worsening nurse-patient ratio and an increasing number of specific nursing tasks have a direct impact on nurses’ quality of work-life. This high workload and poor working environment can lead to poor quality of work-life and eventually, burnout which directly affect nurses’ job performance and professional commitment. This study was aimed to determine the relationships between quality of work-life, burnout and professional commitment among nurses.
