Triangulation And Finite Element Method For A Variational Problem Inspired By Medical Imaging, Tim Komperda, Enrico Au-Yeung

DePaul Discoveries

We implement the finite element method to solve a variational problem that is inspired by medical imaging. In our application, the domain of the image does not need to be a rectangle and can contain a cavity in the middle. The standard approach to solve a variational problem involves formulating the problem as a partial differential equation. Instead, we solve the variational problem directly, using only techniques available to anyone familiar with vector calculus. As part of the computation, we also explore how triangulation is a useful tool in the process.

Insignificant Impacts Of Covid-19 Stay-At-Home Orders On Chicago Air Quality, Adam W.T. Steffeck

DePaul Discoveries

With the onset of the COVID-19 pandemic, reports of air quality improvements around the world resulting from the stay-at-home orders were widespread. However, for Chicago, no significant air quality improvements occurred despite large reductions in private vehicle transportation due to the lack of commuters. The city of Chicago is a nexus for long-haul transportation by trucks and trains, which did not decrease during the pandemic. These transportation sources use mostly diesel fuel engines and emit NO_X, a precursor to tropospheric ozone, and PM_2.5, both of which are harmful air pollutants. Using open access EPA air quality …

This study was comprised of semi-structured qualitative interviews spanning across the United States with 25 leaders and practitioners in permaculture design, a solutions-based ecological design framework to enact positive, systems-level environmental and social change. The objective was to better understand their life paths toward such work. The research showed that higher education is not adequately …

Having A High-Activity Catechol-O-Methyltransferase Allele Is Associated With Elevated Anxiety And Lower Salivary Dehydroepiandrosterone But Also Lower Alpha Amylase In Children With Chromosome 22q11.2 Deletion Syndrome., Jessie Beebe

LSU New Orleans Theses and Dissertations

Chromosome 22q11.2 deletion syndrome (22q11.2DS) results from a hemizygous deletion located on the long arm of chromosome 22. The most common deletion sizes affect between 30 and 90 genes. Individuals with 22q11.2DS may develop serious developmental and psychiatric disorders. The phenotype is highly variable, however, and may be influenced by allelic variation of the retained copies of genes covered by the deletion. I set out to examine the effects of two genes, catechol-O-methyltransferase (COMT) and proline dehydrogenase (PRODH), in relation to anxiety in children and adolescents with 22q11.2DS. Individuals with the major COMT allele (higher activity) have significantly higher anxiety …

Household Perceptions And Patterns Of Crop Loss By Wild Pigs In North India, Bivash Pandav, Lakshminarayanan Natarajan, Ankit Kumar, Ajay A. Desai, Banteibor Lyngkhoi

Human–Wildlife Interactions

Loss to cultivated crops by wild pigs (Sus scrofa) is widespread and can jeopardize low-income farmers. In India, although there is lot of political interest in the problem, efforts to understand the patterns, correlates, and underlying reasons for wild pig conflict continue to be minimal. We quantified loss of wheat (Triticum aestivum) to wild pigs and assessed the spatial patterns of damage in a forest settlement of Van Gujjar (Haridwar, India), which is a dairy-based pastoralist community. We chose a 4-km² cultivated area comprising 400 farmlands (each measuring 0.8 ha and belonging to a family) and …

Data were collected via self-report surveys measuring: (a) knowledge of recommendations for daily fruit and vegetable intake; (b) fruit and vegetable consumption; (c) knowledge of cooking a healthy recipe using vegetables; and (d) desire for farm fresh foods at school. Statistical analyses included McNemar’s and Wilcoxon signed rank tests. The …

Weight Status Perceptions And Food Choice, Christopher R. Gustafson

Cornhusker Economics

Does your weight status—whether your height and weight put you into the normal weight, overweight, or obese category—predict your food choices, or even the types of food you’ll pay attention to when making a choice? What about the weight status you perceive yourself to be? These are important questions because the percentage of the population that is overweight or obese in the U.S.—and world-wide—has been increasing for decades despite a wide range of efforts aimed at slowing/reversing its growth. In the U.S., over 70 percent of the population is overweight or obese. High body weight has numerous consequences for individuals …

Greening The Archive: The Social Climate Of Cotton Manufacturing In The "Samuel Oldknow Papers, 1782-1924", Bernadette Myers, Melina Moe

Journal of Contemporary Archival Studies

This article re-examines the records and correspondence of Samuel Oldknow, a late eighteenth century textile manufacturer, within the context of the environmental humanities. Oldknow’s papers, a portion of which are held at Columbia University, are most often used by economic historians to date the beginnings of the factory wage labor system. We highlight, instead, the environmental implications of Oldknow’s cotton enterprise by juxtaposing documents related to the global reach of Oldknow’s empire with evidence of his transformation of the local landscape of northern England. This process of re-scaling captures a sense of what we call the “social climate” of the …

Informational Signage Increases Awareness Of A Rattlesnake In A Canadian Urban Park System, Jonathan D. Choquette, Alexis V. Hand

Human–Wildlife Interactions

Human–snake conflict results in negative outcomes for people and snakes, and if left unmanaged, could undermine conservation efforts. One approach to managing conflict between people and snakes is to use signage to inform members of the public on the presence of venomous snakes and measures to prevent snakebites. To be an effective tool, however, signs must first be noticed, then read and understood by the target audience. As part of conservation efforts targeting eastern massasauga rattlesnakes (Sistrurus catenatus) in southwestern Ontario, Canada, we tested the effectiveness of signage at increasing awareness of its presence, status and threats, and …

Yield And Economic Performance Of Crop Rotation Systems In South Dakota, Hanxiao Feng, Tong Wang, Shannon L. Osborne, Sandeep Kumar

Case 3847 – Simopithecus Oswaldi Andrews, 1916 (Currently Theropithecus Oswaldi; Mammalia, Primates, Cercopithecidae), Proposed Conservation By Reversal Of Precedence With Cynocephalus Atlanticus Thomas, 1884., Eric Delson, David M. Alba, Stephen R. Frost, Dagmawit Abebe Getahun, Christopher C. Gilbert

Publications and Research

The purpose of this application, under Articles 23.9.3 and 81.1 of the Code, is to conserve the usage of the species-group name Simopithecus oswaldi Andrews, 1916 by giving it precedence over its senior subjective synonym Cynocephalus atlanticus Thomas, 1884. Theropithecus is a common to dominant member of the extinct primate community across Africa after 4 million years ago (Jablonski & Frost, 2010) and often co-occurred with extinct humans (Hominini); fossils are also known rarely across Eurasia (Roberts et al., 2014). Most fossil samples are currently included in Theropithecus oswaldi (Andrews, 1916), which is often divided into chrono-geographic subspecies. Cynocephalus atlanticus …

The Evolution Of Sex Differences In Mandrills (Mandrillus Sphinx): Micro- And Macroevolution, Jerred Klint Schafer

Legacy Theses & Dissertations (2009 - 2024)

Primates show diverse patterns of adaptive color and body size dimorphism produced by inter- and intrasexual selection. However, the specific microevolutionary processes that produce variation in secondary sexual characteristics remain largely unexplored in primates. Furthermore, sexual conflict theory predicts that female and male secondary sexual traits can coevolve in an antagonistic manner and promote speciation. This dissertation explores the microevolution of secondary sexual characteristics in mandrills (Mandrillus sphinx) and the macroevolution of these characters in anthropoid primates. I address the microevolution of mandrill facial coloration and body mass by estimating the heritability, phenotypic selection, and genetic evolution of these traits …

Horticulture Faculty Publications and Presentations

Soybean [Glycine max (L.) Merr.] is a crop of great interest worldwide. Exploring molecular approaches to increase yield genetic gain has been one of the main challenges for soybean breeders and geneticists. Agronomic traits such as maturity, plant height, and seed weight have been found to contribute to yield. In this study, a total of 250 soybean accessions were genotyped with 10,259 high-quality SNPs postulated from genotyping by sequencing (GBS) and evaluated for grain yield, maturity, plant height, and seed weight over three years. A genome-wide association study (GWAS) was performed using a Bayesian Information and …

Ecological Correlates Of Alligator Snapping Turtle Bite Performance, Ashley Herrin Gagnon

Graduate Theses/Dissertations

The Alligator Snapping Turtle (Macrochelys temminckii) is one of many turtle species facing conservation challenges. Nearly extirpated in the 1980s, it is currently the subject of a head-start initiative, of which, any lasting behavioral or physiological effects were—until now—unknown! To evaluate the ability of captive-reared individuals to excel in natural habitats, and to foresee any future research or conservation challenges regarding this animal, I explored a suite of variables that influence bite performance and behaviors including captive or free-ranging status, and environmental conditions including body temperature and season. My results indicated that free-ranging M. temminckii outperform those residing …
