Development Of Advanced Multi-Nozzle Multi-Material 3d Printing, Mohammed Al Ali

Wayne State University Dissertations

Extrusion-based 3D printing methods, such as Direct Ink Writing, are extensively utilized across sectors like biomedical, energy, and electronics, employing a diverse range of materials. However, the lengthy printing times associated with single-nozzle systems limit their application in complex mass production and rapid prototyping. While multi-nozzle systems have attempted to address this issue, they often result in costly, and bulky setups with limited material options. This research introduces a novel multi-nozzle multi-material system that allows for simultaneous 3D printing using bent nozzles. The system is cost-effective, simple in design, and capable of printing a wide range of materials. Its universal …

Natural Selection On Feralization Genes Contributed To The Invasive Spread Of Wild Pigs Throughout The United States, Niek W. G. Barmentlo, Patrick G. Meirmans, William H. Stiver, Joseph G. Yarkovich, Blake E. Mccann, Antoinette J. Piaggio, Dominic Wright, Timothy J. Smyser, Mirte Bosse

Despite a long presence in the contiguous United States (US), the distribution of invasive wild pigs (Sus scrofa × domesticus) has expanded rapidly since the 1980s, suggesting a more recent evolutionary shift towards greater invasiveness. Contemporary populations of wild pigs represent exoferal hybrid descendants of domestic pigs and European wild boar, with such hybridization expected to enrich genetic diversity and increase the adaptive potential of populations. Our objective was to characterize how genetic enrichment through hybridization increases the invasiveness of populations by identifying signals of selection and the ancestral origins of selected loci. Our study focused on invasive …

Influence Of Habitat And Baiting Strategy On Oral Rabies Vaccine Bait Uptake By Raccoons In The Southeastern United States, Jacob E. Hill, Madison L. Miller, Richard B. Chipman, Amy T. Gilbert, James C. Beasley, Guha Dharmarajan, Olin E. Rhodea

United States Department of Agriculture Wildlife Services: Staff Publications

terrestrial wildlife species. However, there is currently a limited understanding of how different baiting strategies influence raccoon (Procyon lotor) uptake of ORV baits in non-agricultural habitats in the Southeastern United States, which may hinder the refinement of ORV management for raccoons in this region. Using a combination of new and existing data, we investigated the role of baited area (0.16 vs 3 km²), bait density (75 versus 150 baits/km²) and season (spring versus fall) on placebo ORV bait uptake by raccoons in four rural, non-agricultural habitats in the southeastern United States (bottomland hardwood forest, …

Prevalence Of Avian Influenza Virus In Atypical Wild Birds Host Groups During An Outbreak Of Highly Pathogenic Strain Ea/Am H5n1, Jourdan M. Ringenberg, Kelsey Weir, Lee Humberg, Carl Voglewede, Mitch Oswald, J. Jeffrey Root, Krista Dilione, Even Casey, Michael Milleson, Timothy Linder, Juliann Lenoch

United States Department of Agriculture Wildlife Services: Staff Publications

The global outbreak of highly pathogenic avian influenza (HPAI) H5N1 Eurasian lineage goose/Guangdong clade 2.3.4.4b virus that was detected in North America in 2021 is the largest in history and has significantly impacted wild bird populations and domestic poultry across the continent. Synanthropic birds may play an important role in transmitting the virus laterally to other wild bird species and domestic poultry. Understanding the dynamics of HPAI in atypical, or nonreservoir, wild bird hosts may help inform management decisions and potential risk factors to both wild and domestic bird populations. Following the confirmation of infections of HPAI H5N1 in domestic …

Evaluation Of Mitigation Translocation As A Management Tool To Reduce Conflicts Between Humans And American Kestrels, Brian E. Washburn

United States Department of Agriculture Wildlife Services: Staff Publications

Raptor‐aircraft collisions (bird strikes) pose a serious safety risk to civil aircraft. Even smaller raptors, such as American kestrels (Falco sparverius), can be problematic within airport environments. Given widespread declines in kestrel populations, public interest, logistical and financial constraints, and other factors, managing kestrels at airports presents some unique challenges. I conducted a study to determine which biological (e.g., age and sex of the bird) and logistical factors (e.g., month and translocation distance) might influence the return of American kestrels live‐captured and translocated from 42 civil airports and military airbases within the contiguous USA during 2016–2021. American kestrels …

Discovery Of A Novel Invasive Rodent Species On Wake Atoll With A Desert Southwest Usa Origin, Antoinette J. Piaggio, Eric Lanners, Daniel R. Taylor, Aaron B. Shiels, Marjorie Matocq, John Eisemann

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive species, particularly omnivorous rodents, have damaged island ecosystems around the world. The unique flora and fauna of island systems have typically not evolved with omnivorous rodents and are heavily impacted by their introduction. Wake Atoll of the southern Pacific Ocean is a 707-hectare coral island complex of three islands managed by the United States Department of Defense (DoD). DoD restricts civilian access to the atoll but aircraft and seacraft regularly visit the island to transport military equipment and to sustain the year-round military and contractor personnel stationed on the atoll. Wake Atoll had been invaded by Rattus rattus complex …

Efficacy Of Gonacon Fertility Control Against Prairie Dogs And Potential For Uses On Other Rodent Species, Aaron B. Shiels, Emily W. Ruell, Jason E. Bruemmer

United States Department of Agriculture Wildlife Services: Staff Publications

Use of a contraceptive (i.e., fertility control) is attractive for rodent management where lethal control is unwanted. Although population reduction is generally unachievable with small-scale, short-term contraceptive use, reduced juvenile recruitment is achievable. The injectable immunocontraceptive vaccine GonaCon (active ingredient: gonadotropin releasing hormone [GnRH]) was registered in 2022 by the United States Environmental Protection Agency (EPA) for controlling fertility of female prairie dogs (Cynomys, a type of ground squirrel) in urban/suburban settings. Here we: 1) describe past research, including a replicated field study in Colorado (GonaCon treatment vs. control sites) testing efficacy of GonaCon in prairie dogs, which …

Agricultural And Ecological Resources Safeguarded By The Prevention Of Wild Pig Population Expansion, Colin Jareb, Kim M. Pepin, Ryan S. Miller, Stephanie A. Shwiff, Sophie C. Mckee

United States Department of Agriculture Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) are one of the most destructive invasive species in the United States, known for causing extensive damage to agricultural commodities, natural resources, and property, and for transmitting diseases to livestock. Following the establishment of the National Feral Swine Damage Management Program (NFSDMP) in 2014, the expansion of wild pig populations has been successfully slowed. This paper combines two modeling approaches across eight separate models to characterize the expansion of wild pig populations in the absence of intervention by the NFSDMP and forecasts the value of a subset of resources safeguarded from the threat of …

Oral Rabies Vaccination Of Raccoons (Procyon Lotor) Across A Development Intensity Gradient In Burlington, Vermont, Usa, 2015–2017, Emily M. Beasley, Kathleen M. Nelson, Dennis Slate, Amy T. Gilbert, Frederick E. Pogmore, Richard B. Chipman, Amy J. Davis

United States Department of Agriculture Wildlife Services: Staff Publications

Management of the raccoon rabies virus variant in North America is conducted primarily using oral rabies vaccination (ORV). When a sufficient proportion of the population is vaccinated (60%), rabies transmission can be eliminated. To date, ORV programs have successfully controlled and eliminated raccoon rabies in rural areas, but there has been less success in urban areas. We studied the proportions of rabies virus neutralizing antibodies (RVNA) in a raccoon (Procyon lotor) population during a 3-year ORV trial in developed areas of Burlington, Vermont, United States. We used a modified N-mixture model to estimate raccoon abundance, RVNA seroprevalence, and …

Distribution And Prevalence Of Antibodies To Trichinella Spp. And Toxoplasma Gondii In Wild Pigs (Sus Scrofa) In The United States, Christopher A. Cleveland, Ellen Haynes, Katherine C. Callaghan, Alinde Fojtik, Sarah Coker, Emily Doub, Vienna R. Brown, Ania A. Majewska, Michael J. Yabsley

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive wild pigs (Sus scrofa) are a reservoir for over 100 viral, bacterial, and parasitic pathogens that are transmissible to humans, livestock, domestic animals, and wildlife in North America. Numerous historical local surveys and results from a nation-wide survey (2006–2010) indicated that wild pigs in the United States act as reservoirs for Trichinella spp. and Toxoplasma gondii, two zoonotic pathogens of importance for human and animal health. Since that time, wild pig populations have expanded and increased in density in many areas. Population expansion of wild pigs creates opportunities for the introduction of pathogens to new areas …

Ethyl-Iophenoxic Acid As A Serum Marker For Oral Baiting Of Tasmanian Devils, Ruth Pye, David Nichols, Sally A. Nofs, Amy T. Gilbert, Andrew S. Flies

United States Department of Agriculture Wildlife Services: Staff Publications

Oral baits containing vaccines, medicants or toxicants have been delivered to a broad range of wildlife species to protect against or treat disease, or suppress populations. Ethyl-Iophenoxic acid (Et-IPA) is used as a biomarker to determine oral bait consumption by wildlife species to assess and refine baiting strategies. Et-IPA is a persistent biomarker in many eutherian mammal species but not in the two marsupial species, swamp wallaby (Wallabia bicolor) and brushtail possum (Trichosurus vulpecula), tested to date. Et-IPA has not previously been evaluated in carnivorous marsupials. The Tasmanian devil (Sarcophilus harrisii), the largest extant …

Estimating Landscape Spread Of A Low-Prevalence Disease Using Multiple Surveillance Methods, Abigail Feuka, Aakash Pandey, Melinda Cosgrove, Megan Moriarty, Anthony Duffiney, Henry Campa Iii, Kurt C. Vercuteren, Kimberly M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

1. Diseases occurring at low prevalence in free-ranging wildlife can be difficult to study and predict at a landscape scale. This problem is compounded by imperfect pathogen detection.

2. We used data from multiple surveillance methods to determine factors influencing spread of a low-prevalence disease, bovine tuberculosis (bTB), among white-tailed deer (Odocoileus virginianus) in a bTB endemic area over a 10-year period. We fit dynamic occupancy models to predict spatial spread of bTB through a county in Michigan, USA, within the bTB endemic area, while accounting for imperfect detection and a suite of ecological processes potentially driving bTB …

Effects Of The Immunocontraceptive Gonacon On Pregnancy In Brucella-Seropositive American Bison (Bison Bison), Rebecca K. Frey, Morgan E. Wehtje, Pauline Nol, Patrick R. Clarke, Jack C. Rhyan, Matthew P. Mccollum, Lowell A. Miller, Douglas C. Eckery

United States Department of Agriculture Wildlife Services: Staff Publications

The purpose of this study was to determine if the number of pregnancies in naturally infected Brucella abortus-positive bison (Bison bison) cows would be reduced over a period of 5 yr after one treatment with 3000 mg gonadotropin-releasing hormone immunocontraceptive (GonaCon) compared to a similar group of naturally infected B. abortus-positive bison cows not treated with GonaCon. In each of the 5 yr, GonaCon-treated cows produced fewer offspring in relation to number of cows than the nontreated cows. Fisher’s Exact test comparing offspring produced during the first reproductive season showed a significant difference between the …

Angiostrongylus cantonensis is a globally distributed nematode and the leading cause of eosinophilic meningitis in humans. As a global hotspot for this disease, Hawaii’s agricultural exports may be contributing to the spread of A. cantonensis. Phytosanitary irradiation doses of 150 or 400 Gy provide quarantine security against multiple insect pests. We evaluated the in vitro and in vivo effects of phytosanitary irradiation on infectious, third-stage A. cantonensis juveniles. In vitro experiments directly exposed juveniles to irradiation doses ranging from 200 to 1,000 Gy. Results showed low mortality and no dose response across all treatments 27 days post-irradiation. …

A Different Approach To Agency Theory And Implications For Esg, Jonathan Bonham, Amoray Riggs-Cragun

Seattle University Law Review

In conventional agency theory, the agent is modeled as exerting unobservable “effort” that influences the distribution over outcomes the principal cares about. Recent papers instead allow the agent to choose the entire distribution, an assumption that better describes the extensive and flexible control that CEOs have over firm outcomes. Under this assumption, the optimal contract rewards the agent directly for outcomes the principal cares about, rather than for what those outcomes reveal about the agent’s effort. This article briefly summarizes this new agency model and discusses its implications for contracting on ESG activities.

Overseeing The Administrative State, Jill E. Fisch

Seattle University Law Review

In a series of recent cases, the Supreme Court has reduced the regulatory power of the Administrative State. Pending cases offer vehicles for the Court to go still further. Although the Court’s skepticism of administrative agencies may be rooted in Constitutional principles or political expediency, this Article explores another possible explanation—a shift in the nature of agencies and their regulatory role. As Pritchard and Thompson detail in their important book, A History of Securities Law in the Supreme Court, the Supreme Court was initially skeptical of agency power, jeopardizing Franklin Delano Roosevelt (FDR)’s ambitious New Deal plan. The Court’s acceptance …

The Sec, The Supreme Court, And The Administrative State, Paul G. Mahoney

Seattle University Law Review

Pritchard and Thompson have given those of us who study the SEC and the securities laws much food for thought. Their methodological focus is on the internal dynamics of the Court’s deliberations, on which they have done detailed and valuable work. The Court did not, however, operate in a vacuum. Intellectual trends in economics and law over the past century can also help us understand the SEC’s fortunes in the federal courts and make predictions about its future.

A Hard Pill To Swallow: The Abysmal Mental Health Standards Of Detained Immigrant Children In The United States, Rama Bankesly

Seattle University Law Review

After setting foot into the U.S., unaccompanied children must learn to navigate academic and legal systems while receiving little support and carrying the heavy burden of effects of trauma on their mental health. They need access to mental health care from qualified professionals, but as this Comment will explain, they systematically fail to receive care, as can be seen in cases like Doe v. Shenandoah Valley Juv. Ctr. Comm’n. In Shenandoah, an unaccompanied child arrived in the U.S. and was placed in a facility that failed to provide remotely adequate mental health care and in fact was subjected …

The Influence Of Genes On The Migratory Timing Of Great Reed Warblers, Emily Fackler

Honors Undergraduate Theses

Many organisms migrate; however, there is a lack of knowledge on the mechanisms that drive migration timing, including which genes play a role. The great reed warbler (Acrocephalus arundinaceus), a migratory bird that breeds in Eurasia and overwinters in sub-Saharan Africa, is an excellent model to study the genetics of migration. Each season, some individuals migrate early, whereas others migrate later in the season. In other words, they exhibit differences in their migratory chronotypes. Past research has identified three candidate genes (TOP1, PEAK1, and CPNE4) that influence the migratory chronotypes of another avian species, …

What Does It Mean To Stand Out? How Visual Design And Presentation Affects Attention And Memory In A Warning Message., Nichlas Waugh, Jeannette Sutton, Laura M. Fischer, Ginder Orton

Emergency Preparedness, Homeland Security, and Cybersecurity Faculty Scholarship

In emergency communication, it is essential to call attention to key information that can be interpreted quickly and remembered easily. Individuals possess a limited number of cognitive resources to allocate to message processing in an emergency. Because of this, they are more likely to allocate attention to messages they are motivated to care about, or to message attributes that stand out. In this study, we focus on how warning messages are attended to when they are viewed in a busy media environment and ask the question: “What does it mean to stand out?” To address the research questions, we used …

Reactive Aldehyde Species (Rasp) Inhibitors Sequester Maa-Adducts And Reduce Pro-Inflammatory Cytokines, Duncan Works

Posters and Presentations: College of Medicine Students

Background: Post-translational modifications of self-proteins have been implicated in the pathogenesis of Rheumatoid Arthritis (RA). One of these protein modifications termed malondialdehyde-acetaldehyde-adduct (MAA) has recently gained interest for its involvement in RA. This protein adduct contributes to inflammation by inducing immune cells to generate pro-inflammatory cytokines, T-cell specific responses, responses and circulating autoantibodies. Recently, novel reactive aldehyde species (RASP) inhibitors (ADX-629 and ADX-246) became available that have been shown to prevent the formation of MAA adducts by covalently binding and sequestering MDA and AA in a mouse model of alcoholic liver disease. These inhibitors prevented the release of key inflammatory …

Improving The Most Gg Model To Predict Environmental Impact And Improve On Farm Grass Growth Prediction, Laeticia Bonnard

Theses

The increasing need for highly productive and eco-friendly agriculture is driving demand for decision-support tools to assist agricultural operators in managing systems more precisely and sustainably. Although grasslands provide a cost-effective option for ruminant production and can offer many environmental benefits (biodiversity, carbon storage etc.), grasslands management is challenging due to the inherent climate and soil sensitivities and their potential negative impact on water quality. In Ireland, the Moorepark Saint Gilles Grass Growth (MoSt GG) model was developed for the dual purposes of research-based simulations and on-farm grass growth prediction for farmers. The objective of this thesis was to improve …

Field And Laboratory Evaluation Of The Interactions Between Pesticides And The Gut Microbiome In Honey Bees (Apis Mellifera), Macee R. Mitchell

EWU Masters Thesis Collection

Western honey bees (Apis mellifera) are important pollinators yet are threatened by a combination of factors such as poor nutrition, pathogens, parasites, and pesticide use. Bees encounter numerous pesticides while foraging (e.g. imidacloprid, a neonicotinoid insecticide) or in the hive colony (e.g. Tau-fluvalinate, a miticide commonly used to treat Varroa mite parasites). Similar to most organisms, the gut microbiome is important for bee health, metabolism, and behavior, however it is not well known how environmental factors like pesticides impact their gut bacterial symbionts. I hypothesized that 1) pesticide concentrations in bees are correlated with gut bacterial community structure, and 2) …

Envisioning Munster Technological University As A Trauma-Sensitive University, Marie Singleton

Theses

Trauma-informed care works on the assumption that individuals utilizing relevant services have experienced trauma (Palmer, 2020). The trauma-informed approach focuses on providing empathy and compassion to create healing relationships and ensure accessibility for all service users. This approach is aimed at understanding, identifying, and addressing trauma in organisations by making changes to practices, policies, and procedures (Champine et al., 2022). Substance Abuse and Mental Health Services Administration (SAMHSA) (2014:10) states that ‘trauma results from an event, serie s of events, or set of circumstances that is experienced by an individual as physically or emotionally harmful or threatening and that has …
