Mechanical Property And Thermal Stability Characterization Of Additively Manufactured Chicken Feather Fiber/Polybutylene Succinate (Pbs) Green Composites And In-Situ Pore Detection From Fdm 3d Printing Videos, Md Shariful Islam

All Theses

The poultry industry generates millions of tons of chicken feathers annually, most of which are underutilized and discarded as waste materials. Chicken feather fiber (CFF), primarily composed of keratin, possesses low density, biodegradability, and favorable mechanical properties, making it a promising reinforcement for sustainable composite materials. This research primarily focused on developing sustainable bio-composites using poultry waste, chicken feather fiber, and biodegradable polymers, specifically Polybutylene Succinate (PBS), for additive manufacturing applications. Composite filaments of varying fiber loadings (0.5, 1, and 2 wt%) were produced through filament extrusion and processed into test specimens using fused deposition modeling (FDM).

Mechanical properties were …

The Crumbling Flsa Collective Action: How Bristol-Myers Squibb Shapes The Reach Of Federal Wage Claims, Elijah Phillips

Southern Illinois University Law Journal

The Fair Labor Standards Act (FLSA) was meant to help level the playing field and help workers create a healthy working environment for themselves. However, today, due to the Supreme Court’s decision in Bristol-Myers Squibb v. Superior Court of California, San Francisco County and lower federal courts’ eagerness to expand personal jurisdiction, the FLSA is crumbling. Workers now face great difficulty in combining their claims in collective actions through the FLSA. When workers from many states do combine their claims, the workers often face dismissal from the action because not all claims have sufficient connections with the chosen litigation forum. …

Mozgus, Damian Cerda, Madison Lopez

Computer Science and Software Engineering

The indie game market is flooded with genre experiments, yet few successfully combine fast-paced action with meaningful strategic decision-making. Our project aims to fill this gap by creating a game that fuses top-down action combat with resource-management tycoon mechanics. We found that in many games, the management phases lack mechanical stakes. Our goal was to intertwine these systems so that choices made in one phase meaningfully impact the other.

Prevalence Of Shiga Toxin Producing Escherichia Coli In Illinois Bison Herds, Adam M. Baldocchi

Fragmentation In The U. S. Fed Cattle Market: Implications For Price Transparency And Discovery, Taralee M. Hudson

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The U.S. fed cattle market is one plagued by recurring stakeholder concern. Market participants frequently raise questions about the transparency of fundamental information under existing reporting frameworks, and the extent to which Private Negotiation, the dominant trading institution, effectively facilitates price discovery. Although extensive research has sought to address these issues, much of it has failed to account for the market’s increasingly fragmented structure. This thesis is comprised of three chapters that collectively examine price transparency and discovery through the lens of market fragmentation. Each chapter presents research related to the fed cattle market and is intended to stand …

Realism, Truth, And Commitment: An Exposition And Critique Of Michael Devitt's Constitutive Account Of Realism, Samuel Elias Hobbs

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Michael Devitt argues in Realism and Truth that positive semantic issues are not constitutive of realism concerning the mostly impersonal external world. This is motivated by his second maxim which prescribes that the metaphysical (ontological) issue of realism is to be (sharply) distinguished from any (positive) semantic issue. Devitt’s argument is that his view of realism, entitled ‘Realism’, doesn’t entail and isn’t entailed by any doctrine of truth.

This dissertation presents a critique of the argument indicated above and, thereby, Devitt’s second maxim. I present Devitt’s account of Realism and his overview of theories of truth. I next present Devitt’s …

Characterization Of Mitochondrial Dna Repair Components And Repair Choices At Targeted Double-Strand Breaks In Arabidopsis Thaliana, Moira Rodriguez

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Plant mitochondrial genomes are complex when compared to most other eukaryotic mitochondrial genomes. They are large and variable in size, expand and rearrange frequently, abundant in non-tandem repeats, but maintain a very low synonymous substitution rate in the remaining coding regions. Many of these complexities can be explained by the increased use of double-strand break repair for DNA damage. To advance the understanding of mitochondrial genome dynamics as it relates to double-strand break repair, we performed a forward genetics screen to identify proteins involved in DNA repair in plant mitochondrial genomes. Through this screen, we identified an RNA/DNA helicase, Suv3, …

Recovery And Characterization Of Moraxella Species From Bovine Specimens, Laura G. Leger

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The family Moraxellaceae is made up of a diverse group of 24 named species that fall into three phylogenetic groups. While most Moraxella spp. act as commensal respiratory and/or ocular flora of mammals, some are associated with disease. One of these diseases, infectious bovine keratoconjunctivitis (IBK), has significant welfare and economic impacts to both cattle and cattle producers. Moraxella bovis is the only experimentally determined cause of IBK, however, an association of Moraxella bovoculi with disease has been proposed.

The Graphic Shift: Leveraging Superhero Graphica To Un-Ban Critical Conversations In The Secondary English Language Arts Classroom, Avery Clason

Department of English: Dissertations, Theses, and Student Research

This thesis investigates the challenges that books are receiving during an era of social and political turmoil based on their content. Understanding why these books are polarizing for most readers and the general public is in direct connection with finding different books that can harbor the same conversations about dense topics and cultivating connections between students, the text, the world, and themselves. While there has been a search to find alternate books that are not considered "political flashpoints,” there has been limited research into the use of superhero graphica in the ELA classroom, especially in connection to utilizing this genre …

Pfos And Lung Injury: A Review Of Human And Experimental Evidence, Farzana Hakim

Theses and Dissertations

Human epidemiological research has shown the adverse health consequences of long-term accumulation of per- and polyfluoroalkyl substances (PFAS) in human tissue. Specifically, this review will examine the relationship between PFAS exposure, impaired immune system functioning, and an elevated risk of respiratory disease using both human and experimental data. Research on human populations indicates that children exposed to PFAS have lower levels of antibodies to vaccines; those children prenatally exposed to PFAS are more susceptible to upper respiratory infections; and that adult humans have a higher incidence of chronic obstructive pulmonary disease (COPD). Additionally, experimental studies demonstrate that PFOS and PFOA …

Practice?, Pei Chen

Theses

3D animation is a combination of art and technique. Art serves to convey your perspective, express beauty, tell stories, and more. However, to accomplish these goals, we need solid technical support. Only by paying attention to both, can we achieve excellent results. The title of this film is “Practice?”, which is a deliberate pun. On one hand, "practice" refers to the martial arts training sequences of the character, during which his master provides guidance, intervenes in his movements, and progressively increases the difficulty. On the other hand, "practice" also symbolizes my own artistic and technical experimentation—exploring and refining skills in …

Desiccation Tolerance In Tetradesmus Green Algae, Kristen Patten

Theses

In the face of the global climate change threat, understanding the adaptations that organisms have evolved to handle environmental variation is of particular interest to scientists. With climate change impacting global water availability and increasing the risk of drought for many traditional agricultural areas in the United States (IPCC, 2014, IPCC, 2021, and Kuwayama et al., 2019), desiccation tolerance in vegetative states is one adaptation that is currently receiving a lot of attention. Green algae are particularly useful organisms for understanding this adaptation due to their ubiquity across environments, which has given rise to independently evolved organisms displaying different levels …

Effects Of Response-Independent Food Delivery During Timeout On Timeout Punishment, Haillie Mcdonough

All NMU Master's Theses

Timeout is a signaled, response-dependent, and time limited period in which the prevailing schedule of reinforcement is suspended. Timeouts are one of the most frequently used punishment procedures in clinical and parental practices. Even though timeout is a common punishment practice, recent research suggests that implementation errors, fidelity failures, occur at high rates in practice. The present study evaluated how failures in procedural fidelity alter the efficacy of timeout as a punisher by exposing rats to conditions in which response-independent reinforcers were delivered during timeout. During baseline conditions, no timeouts were delivered and rats’ lever-pressing produced food reinforcers according to …

Weaponized Deepfakes: A Low-Resourced Attacker Threat Assessment, Joshua David Labelle

Master's Theses and Capstones

The democratization of Artificial Intelligence and Machine Learning (AI/ML) tools, combined with the short-form nature of modern media consumption, has created a ripe landscape for generating and weaponizing synthetic media. The availability of pre-trained, open-source generative models enables would-be attackers, who lack funding and enterprise-grade hardware, to conduct convincing information-based attacks that harm, manipulate, and deceive. This thesis aims to model this threat actor using an open-source deepfake generation pipeline that requires minimal computational resources and is capable of producing deepfakes in the audio, image, and video domains. This model is then used to identify, measure, and evaluate the capabilities …
