Characterizing Environmental Background Microflora And Assessing Their Influence On Listeria Persistence In Dairy Processing Environment, Vaishali Poswal, Sanjeev Anand, Brian Kraus

Dairy Science and Food Science Faculty Publications: 2022 to Present

Listeria monocytogenes (Lm) may persist in food processing environments (FPEs) alongside diverse background microflora. While microbial communities in FPEs can in- fluence Lm survival, their role in supporting or suppressing its growth remains unclear. This study aimed to characterize the microflora in floor swabs and air samples collected from a dairy processing facility across three seasons and assess their potential impact on the growth of a Lm test strain previously isolated from a dairy processing environment. A total of 167 environmental isolates, representing 30 bacterial genera, were identified. Pseudomonas was consistently prevalent across all sample types. Seasonal shifts in bacterial …

Exploring Antimicrobial Performance And Compostability Of A Pectin-Based Film, Jessica Hardiman

All Theses

Packaging is considered one of the most important parts of the food supply chain. Packaging affects many aspects of the food product, such as acceptability, safety, nutritional quality, and it also provides a means of communication with the consumer. Although many people are aware of the great benefits packaging provides to the food sector, fewer think about the repercussions that occur from the waste that is generated from packaging, or the waste from the food inside the package. There is little research done on the development of compostable and antimicrobial packaging, which could reduce plastic and improve food safety. In …

Land Use Matters: The Interactions Between Soil Characteristics, Ecosystem Cycling, And Anthropogenic Influences At Valley View Farm, Heidi Nydam

Standard Theses

Soil characteristics are the foundation of forest and agricultural productivity. Therefore, understanding how soils change as a reflection of changing landscapes is essential for sustainable management. Valley View Farm is a small, multi use farm in central southern Maine, which seeks to balance conservation and successful farming in terms of providing for the owner and the surrounding community. There are a variety of management practices across the farm, but three distinct areas were examined: the Older Forest, which has been only minimally managed for the last 100 years; the Newer Forest, which was selectively logged 15 years ago and left …

What's For Dinner: A Carbon And Nitrogen Stable Isotope Analysis Of Carcinus Maenas In Maine Salt Marshes, Sydney G. Schuster

Standard Theses

Carcinus maenas, AKA the European Green Crab, is a highly invasive species that has established populations in many non-native sites, altering trophic systems and ecological well-being. In recent years, C. maenas populations have drastically increased throughout the Gulf of Maine, and have been particularly harmful to Maine’s estuarine and intertidal ecosystems (Miller et. al., 2014). In this study, we used carbon and nitrogen stable isotope analysis of green crab tissue to examine their dietary patterns, with the hope of parameterizing how they are feeding in and depleting the resources of Maine’s coastal ecosystems. Specimens for this study were collected from …

3d Bioprinting Of Hydrogel Scaffold Skin Equivalents For Cosmetic And Drug Testing, Allison Reno

All Dissertations

Tissue engineering scaffolds are a crucial element of generating larger 3D tissue equivalents for modeling and clinical grafting. Currently, much of scaffold technology has not been significantly updated since the introduction of manually pipetted hydrogels and electrospun fiber scaffolds. Both of these approaches have their advantages and disadvantages, but neither utilize emerging biofabrication techniques such as advanced 3D bioprinting and plotting. In addition to more precision in the outer geometries of the scaffold, the use of bioprinting also introduces the ability to shape hydrogels into very intricate porous inner patterns within the outer geometries. This allows for the design of …

Investigating Fatty Acid Influence On West Nile Virus In Mosquitoes And Birds, Hayley Moree

Honors Program: Senior Projects (Public)

Vector-borne diseases, including Zika virus (ZIKV), Dengue virus (DENV), and West Nile virus (WNV), pose considerable global health threats, accounting for over 400 million infections and more than 700,000 deaths annually. Many vector-borne diseases are within the Flaviviridae family. Despite this, effective treatments have not been found for some flaviviruses. Flaviviruses exploit host cellular machinery to facilitate their replication and survival, reprogramming metabolic pathways, including lipid metabolism. Lipids play essential roles in the viral life cycle, providing structural components for the viral envelope, enabling membrane rearrangements for replication complexes, and supplying energy resources necessary for particle assembly.

Targeting lipid metabolism …

Effects Of Intradermal Injections Of Lipopolysaccharide On The Local And Systemic Acute Inflammatory Responses In Turkeys, Delaney F. Roberts

Poultry Science Undergraduate Honors Theses

In chickens, the growing feather (GF) pulp has been established as a cutaneous bioassay to monitor and assess tissue/cellular immune activities in response to intradermal (i.d.) injections of test materials. The objective of this pilot study was to determine the suitability of the GF bioassay in turkeys by examining the acute inflammatory responses initiated by i.d. GF-pulp injections of lipopolysaccharide (LPS). For this, three, 5-wk-old turkey poults were used. Two poults had 8 GFs injected (10 μL/GF) with low (L)-LPS (0.1 μg/GF) and 8 GFs with high (H)-LPS (1 μg/GF), while a third poult had 8 GFs injected with endotoxin-free …

The Consequences Of Asexual Misrepresentation In Queer Media, Isaac Chenoweth

RhetTech

Asexuality has been misrepresented in queer-affirming media to an alarming extent. Queer media has often villainized, erased, or entirely excluded openly asexual characters, one defining moment being the erasure of Jughead’s asexual identity from Riverdale in 2019. Organizations such as the Asexual Visibility and Education Network (AVEN) as well as the many universities that celebrate asexual pride week have been instrumental in spreading awareness on the community’s misrepresentation. Through the comparative analysis of queer media’s portrayals of asexuality versus other queer identities, alongside the textual analysis of works done by prominent asexual figures, this study will examine the systematic forces …

Cannibalism, Consumerism, Colonialism And Love In Contemporary Western Media, Jules Perez

RhetTech

This paper examines the role of the cannibal in contemporary western media by examining the novel Tender Is the Flesh by Agustina Bazterrica, the short story Meat by Mariana Enriquez, and the movie Bones and All starring Timothee Chalamet and Taylor Russell. By analyzing these pieces of media, one can see the ways in which cannibalism as a literary device acts as a method of reflection and disarmament to prominent western philosophies surrounding ideas of consumerism, colonialism and love.

The Movement Ecology, Ranging Patterns, And Territoriality Of Azara’S Owl Monkeys (Aotus Azarae) In The Argentinean Chaco Forest, Jeremy D. Pustilnik

Master of Environmental Science Theses

Azara’s owl monkeys (Aotus azarae) are small, pair-living, socially monogamous primates that inhabit the Chaco Forest of South America. Their activity and life history patterns have been particularly well studied, however, their movement ecology and ranging patterns within their home ranges remains largely unknown. Herein I descriptively analyze these patterns with respect to time, space, ambient environment, and physical environment using spatial information on five owl monkey groups that were followed over the course of a year between 1998 and 1999 at a multi-decade-operating field site near Formosa, Argentina. Analysis of distance and speed moved during different diel …

Critical Period Constraints And Learning Strategies: Balancing Incidental And Intentional Vocabulary Acquisition In Japanese Second Language Acquisition, Emma Ward

Honors College Theses

The Critical Period Hypothesis (CPH) supposes there is a biologically determined window during which language acquisition occurs most efficiently. This theory has profound implications for Second Language Acquisition (SLA) research, suggesting the timing of language learning can significantly impact one's ability to achieve native-like proficiency. As vocabulary acquisition is a fundamental aspect of language learning, understanding how to optimize learning strategies within the constraints imposed by the critical period is essential for maximizing language learning outcomes. The Japanese language, with its complex writing systems and unique syntactic structures, presents significant challenges for learners, especially those who begin learning the language …

Heat Induced Diagenesis And Osteometrics: An Experimental Approach To Assessing Thermal Alterations To Forensic Anthropological Data On Dry Bone, Audrey Holbeck

Department of Anthropology: Theses and Student Research

Fire appears in forensic casework in instances of arson, vehicle fire, house fire, to conceal evidence, or, in increasing contemporary frequency, wildfire, as a result of climate change. Thermal alteration is a destructive process to osseous material and can impact the accuracy of identification methods and trauma analysis by alteration of the structure, appearance, and morphology of human remains. This study seeks to validate previous research on the metric and morphological changes bone undergoes when exposed to extreme heat, and how that may impede estimation of metric features such as stature. Three long bones, a humerus, femur, and tibia, from …

Comparative Analysis Of Gunshot Trauma And Decomposition In Southeast Nebraska, Alexandra C. Tieken

Department of Anthropology: Theses and Student Research

Accurately identifying gunshot trauma (GST) in forensic anthropology remains a significant challenge, particularly in distinguishing the effects it has on decomposition. This study investigates how different types of gunshot trauma influence the rate and characteristics of decomposition in a humid continental climate, specifically southeastern Nebraska. Utilizing Sus scrofa domesticus (domestic pigs) as human proxies, four pigs were euthanized by professionals and subjected to controlled conditions at the Reller Prairie Field Station. Three pigs were inflicted postmortem with close-range gunshot trauma using a 9mm handgun, a 12-gauge shotgun, and an AR-15 rifle, while a fourth served as a trauma-free control. For …

Wildfire And Decomposition: A Taphonomic Analysis Of Thermal Alterations And Decomposition, Ashley Novak

Department of Anthropology: Theses and Student Research

Within the field of forensic anthropology, practitioners may be faced with remains that have been thermally altered by thermal alterations caused by wildfire. Within the field, very little research has been conducted examining how these thermal events impact rates of decomposition. While research has been conducted generally on the effects of thermal alteration on decomposition, these studies do not look through this lens and provide answers to the question of how do thermal alterations caused by wildfires affect rates of decomposition? This research examines the effects of thermal alteration caused by wildfire on the rate of decomposition. A decompositional study …

Trends In Dna Aanalysis To Determine Postmortem Interval: A Systematic Lilterature Review, Victoria S. Kashkin

Department of Anthropology: Theses and Student Research

Forensic taphonomy is a recently popular field within forensic anthropology with limited research in the Central Great Plains. Given decomposition varies by region, more studies must be done to understand aspects of decomposition in this region. However, it is one of the most important subfields of forensic anthropology since determining postmortem interval (PMI) is extremely important to successfully identifying a missing individual if other indications of who the individual is are nonexistent. In this study, a systematic literature review was conducted to answer what trends are seen in research being done for using DNA to determine PMI, and what methods …

Empowering Diversity: A Comprehensvie Approach To Minority Risk Management Education, Jahqethea Johnson

Applied Science Program: Theses

Federal programs are pivotal to the foundation of the United States agricultural sector. Program payments impact the economic well-being of agricultural producers, yet accessibility, outreach and education disparities remain prevalent among socially disadvantaged producer and agriculturists. From 2020-2024, an average of $21.7 billion dollars in federal agricultural payments have been paid to producers. Although federal funding historically supports commodity crops, livestock producers also depend on a distinct set of federal risk management programs, which are often less visible but pertinent for operational sustainability. There is a growing focus on the need for addressing disparities faced by socially disadvantaged producers and …

Voluntary Intermittent Access To Combined Alcohol And Nicotine In Mice—Consumption And Withdrawal Effects, Alyssa M. Potts

Undergraduate Honors Thesis Collection

The prevalence of alcohol and nicotine use is widely known, though the co-abuse of the two is often understudied. Studies have shown that nicotine dependence and daily nicotine consumption increase with higher levels of alcohol consumption1. Nicotine use has been shown to decrease the subjective effects of alcohol and increase alcohol craving. Previous studies using the intermittent access (IA) paradigm in C57BL/6J (B6) mice have shown that B6 mice readily increase or escalate consumption of alcohol in this paradigm. Still, there is little information on alcohol and nicotine co-consumption and withdrawal using the IA paradigm. The goal of this study …

The Evolution Of Dental Aesthetics: An Artistic And Cultural Journey Through History And Race, Naya L. Weems

Undergraduate Honors Thesis Collection

This thesis explores the intersection of art, dentistry, race, and healthcare through a critical analysis of how visual culture has shaped societal perceptions of dental aesthetics from antiquity to the modern day. Beginning with ancient Egyptian hieroglyphs and Renaissance anatomical drawings, the study traces how artistic portrayals of teeth evolved into tools of both medical education and social hierarchy. Particular attention is given to the racialization of dental aesthetics, examining how caricatures, colonial pseudoscience, and exclusionary marketing practices contributed to enduring stereotypes and disparities in oral healthcare. Through the lens of cultural symbols like grills—once markers of status among Etruscans, …

The Geopolitics Of Digital Regulation, Aziz Z. Huq

University of Chicago Law Review

Contemporary regulation of new digital technologies by nation-states unfolds under a darkening shadow of geopolitical competition. The United States government operates simultaneously in a domestic political environment dominated by oligopolistic firms competing to expand, and in an international political environment wherein it competes against other sovereign nations by cultivating and deploying digital technological capacities for geostrategic economic and military ends. Thanks to the ensuing burst of crosscutting pressures, both national and supranational regulation can take on surprisingly reticulated, even baroque or perverse, forms.

Three recent monographs offer illuminating and complementary maps of these geopolitical conflicts and the national responses to …

Untethered And Unraveled: Isolated Motherhood In The Liminal Stage, Ashton K. Wronikowski

All Theses

In examining Kate Chopin’s The Awakening alongside anthropologic theories of liminality, this paper examines the becoming women traverse as they transition between various social roles: girl, woman, mother. Edna is a maternal character attempting to unweave herself from her roles as mother and wife, and she finds this desire to go backwards to the freedom she experienced as a girl is proven to be impossible. The unmooring of her psyche and her subsequent suicide is indicative of a failure, not of her own accord, but in the social preparation and support she receives within her new identity. Social anthropologists further …

The Great Animal Rights Debate: From The Past Into The Present, Dayna Wiley

Celebrating Scholarship and Creativity Day (2018-)

Animal rights are not a novel concept, and everyone has their own beliefs about where animals should fit into the hierarchy of life. Not so different from today, a debate occurred in the ancient world between the Stoics, represented by Aristotle, and Plutarch, with each questioning whether animals are capable of rational thought or feelings, and therefore whether they are deserving of justice. There is much to learn from the ancient world about the modern debate on animal rights, and there is a striking comparison between this ancient debate and the modern questions of animal rights. But how similar are …

Reading The Minoan "Sacral Knot", Rylie Owen

Celebrating Scholarship and Creativity Day (2018-)

The sacral knot, a term first coined by Sir Arthur Evans, is an iconic symbol in Minoan iconography, but there is surprisingly little information about it. Various interpretations have been suggested regarding the meaning of this knot, the most popular and well-known being a religious function.There is no doubt that the so-called "sacral knot” had an important meaning in Bronze Age Greece, with a number of depictions showing the knot alongside other significant symbols, such as bulls, figure-of-eight shields, and lions. However, the knot also appears to function as a symbol on its own. This analysis draws from a compilation …

Alpha-Smooth Muscle Actin-Expressing Dermal Sheath Cells Are A Major Cellular Contributor To Heterotopic Subcutaneous Ossifications In A Mouse Model Of Albright Hereditary Osteodystrophy., Patrick Mcmullan, Peter Maye, Sierra H Root, Qingfen Yang, Sarah Edie, David Rowe, Ivo Kalajzic, Emily L Germain-Lee

Faculty Research 2025

Heterotopic ossifications (HOs) are the pathologic process by which bone inappropriately forms outside of the skeletal system. Despite HOs being a persistent clinical problem in the general population, there are no definitive strategies for their prevention and treatment due to a limited understanding of the cellular and molecular mechanisms contributing to lesion development. One disease in which the development of heterotopic subcutaneous ossifications (SCOs) leads to morbidity is Albright hereditary osteodystrophy (AHO). Albright hereditary osteodystrophy is caused by heterozygous inactivation of GNAS, the gene that encodes the α-stimulatory subunit (Gαs ) of G proteins. Previously, we had shown using our …
