Rapid Differentiation Of Moraxella Bovoculi Genotypes 1 And 2 Using Maldi-Tof Mass Spectrometry Profiles, Matthew M. Hille, Aaron M. Dickey, Kara Robbins, Michael L. Clawson, John Dustin Loy

School of Veterinary and Biomedical Sciences: Faculty Publications

Moraxella bovoculi is the most frequently isolated bacteria from the eyes of cattle with Infectious Bovine Keratoconjunctivitis (IBK), also known as bovine pinkeye. Two distinct genotypes of M. bovoculi, genotype 1 and genotype 2, were characterized after whole genome sequencing showed a large degree of single nucleotide polymorphism (SNP) diversity within the species. To date, both genotypes have been isolated from the eyes of cattle without clinical signs of IBK while only genotype 1 strains have been isolated from the eyes of cattle with clinical signs of IBK. We used 38 known genotype 1 strains and 26 known genotype …

Enigmatic Mediterranean Silk Quilts, Kathryn Berenson

Textile Society of America: Symposium Proceedings

Nearly two dozen centuries-old, corded quilts and fragments made of jewel-toned silks rest in North American and European collections. Expertly designed, they are variously stitched with imagery of ships sailing over waters that teem with fish, musicians who play amidst animals that gambol and prance to their music, armed hunters and their dogs in pursuit of boar, wolf, and even lion, and arcaded galleries where half-dressed women pose beneath the arches. Double-headed eagles, a symbol of both political and religious significance, and roundels featuring profiles of men wearing turbans or crowns, are also common motifs.

Each quilt is completely reversible; …

Transformative Power Of Stitchery: Sashiko From Cold Regions Of Japan And Embroidery Work Of The Nui Project, Yoshiko Iwamoto Wada

Textile Society of America: Symposium Proceedings

This paper seeks to reveal the transformative power of stitchery by examining textile practices in Japan and articulating how a threaded needle can be viewed as the co-agent of stitchers, infusing their materials with properties in a “processual” and relational manner that reflects the currents of their lifeworld.^[1] I will contrast and compare two practices, one ancient and one modern, one responding to life’s necessities and the other simply to the act of stitching. In the ancient world, stitchery was essential for human survival, and later in rural Japan, sashiko stitchery was a medium that connected textiles with daily …

Textile Memory In Colchane: Weavers Revitalizing The Aymara Tradition, Soledad Hoces De La Guardia

Textile Society of America: Symposium Proceedings

In Aymara culture, textiles have played a fundamental role as highly valued community possessions and significant media for ritual and tradition. In Chilean territory, the Colchane community has been fortunate, because they have here retained, with fidelity and vigor, their culture and traditional textile practices. However, the average age of active weavers is rising and those younger do not have the technical expertise of their elders, which has led to the loss of a significant part of traditional technical knowledge.

To not forget the “handwork” became an urgent concern for artisans in the community, members of the Aymar Warmi association, …

Viscacha: Luxury, Fate And Identification In Precolumbian Textiles, Elena Phipps, Caroline Solazzo

Textile Society of America: Symposium Proceedings

Since the sixteenth century, references by Spanish chroniclers to the use of chinchilla hair (Andean rodents of several species including viscacha) by Andean weavers indicate that the fine hair of these animals had been incorporated into textiles. Their fine soft hair, often mottled in color, has distinctive characteristics which vary and, as a result, make them difficult to identify. Some archaeological finds, primarily in Chile have reported viscacha skins and fur bags, but few if any reports have identified the presence of textiles or spun yarns that incorporate this special fiber. The depiction of the animal takes on special meaning …

Applied Injected Air Into Subsurface Drip Irrigation: Plant Uptake Of Pharmaceuticals And Soil Microbial Communities, Matteo D'Alessio, Lisa M. Durso, Clinton Williams, Christopher A. Olson, Chittaranjan Ray, Ellen Paparozzi

Nebraska Water Center: Faculty Publications

The growing global food security crisis is complicated by the need for increased crop production with less arable land and limited water resources. Reuse of treated wastewater for agricultural irrigation is becoming more common, often paired with other conservation measures such as subsurface drip irrigation (SDI). Passively injecting air into SDI systems increases crop yields and overcomes root zone wetting issues. However, when used with treated irrigation water, contaminants in the water might be taken up by the crops. This paper investigates the impact of air-injected water containing caffeine, carbamazepine, and gemfibrozil on plant uptake and soil microbial communities in …

Transcriptomic Data-Driven Discovery Of Global Regulatory Features Of Rice Seeds Developing Under Heat Stress, Mohammad Mazharul Islam, Jaspreet Sandhu, Harkamal Walia, Rajib Saha

Department of Chemical and Biomolecular Engineering: Faculty Publications

Plants respond to abiotic stressors through a suite of strategies including differential regulation of stress- responsive genes. Hence, characterizing the influences of the relevant global regulators or on stress- related transcription factors is critical to understand plant stress response. Rice seed development is highly sensitive to elevated temperatures. To elucidate the extent and directional hierarchy of gene reg- ulation in rice seeds under heat stress, we developed and implemented a robust multi-level optimization- based algorithm called Minimal Regulatory Network identifier (MiReN). MiReN could predict the minimal regulatory relationship between a gene and its potential regulators from our temporal transcriptomic dataset. …

Climate Change And Grief: An Overview Of The Mental Health Effects Of Climate Change And How Biodiversity Loss In The Great Plains Affects Our Emotional Wellbeing, Luke Andersen

Department of Environmental Studies: Undergraduate Student Theses

While it is known that our changing climate is predicted to have dire consequences, there is less discussion taking place about the potential mental health effects and outcomes of those consequences. Many articles outline the mental health consequences of climate change, but they all discuss similar ideas and theories that don't necessarily generate further topics to explore. A topic that remains unexplored is that of ecological grief, which is our emotional response to ecological loss. The hypothesis being tested in this research project is that people will feel relatively strong grief-related emotions (i.e. anger, sadness) when imagining the loss of …

Environmental Factors On The Arctic Food Chain, Sydney Hansen

Department of Environmental Studies: Undergraduate Student Theses

As the Arctic is encountering many environmental changes, a multi-species meta-analysis was conducted from peer-reviewed scientific data gathered from the University of Nebraska-Lincoln (UNL) library’s bibliographic databases to determine 1) the main polar warming impacts on species of the Arctic food web such as polar bears, ringed seals, Arctic cod, copepods, and primary producers, 2) determine climatic impacts by looking at population sizes and migratory patterns over several years, and 3) discover impacts of a top-down cascade and look into conservation efforts. In the Arctic, species within its’ ecosystem are experiencing more dramatic impacts from climatic warming because of the …

A Comparative Analysis Of The Reception Of Laudato Si’ By Progressive And Traditional Catholics, Mikayla Dorff

Department of Environmental Studies: Undergraduate Student Theses

This study considers the impacts of religion, specifically Catholicism, on environmental views. In 2015, Pope Francis published an encyclical entitled Laudato Si’: On Care for Our Common Home. In this encyclical, Pope Francis calls all humans to an “ecological conversion” and identifies environmental stewardship as a Catholic responsibility. Progressive Catholics embraced Laudato Si’ and its messages, while traditional Catholics condemned the encyclical. In this study, a comparative literary analysis is conducted to determine why traditional Catholics reject the encyclical while progressive Catholics applaud it. Initiatives stemming as a direct result from Laudato Si’ are also examined. The study found …

Nutritional Value Of Crops Affected By Elevated Carbon Dioxide Concentrations In Atmospheric Conditions, Alex Joseph Cusimano

Department of Environmental Studies: Undergraduate Student Theses

This research was conducted to evaluate the effects of rising atmospheric carbon dioxide concentrations, and the nutritional quality of crops. Using Free Air CO2 Enrichment (FACE) and Decision Support System for Agrotechnology Transfer (DSSAT) to simulate elevated carbon dioxide levels, more review of previous literature was studied. Studies found that although there is a negative loss of nutrient availability, there are major signs that nutrient deficiencies. Nitrogen(protein), Iron, and Zinc are the most impacted with elevated atmospheric CO2 conditions. Further research and experiments regarding long term plant growth should be considered moving forward. With only limted situations and different CO2 …

What Are The Impacts Of Plastic Pollution On Sea Turtles And How Can We Prevent Them?, Stacey Safarik

Department of Environmental Studies: Undergraduate Student Theses

This paper will address the impacts of plastic pollution on sea turtles and how humans can combat the issue. Sea turtles are often harmed due to human activities because the ocean is used as a dumping ground for trash, and humans need to take it upon themselves to change this. The purpose of this project was to learn how plastic can impact the lives of sea turtles, and to find out if there are prevention efforts in place. A thematic literature review was conducted in order to find all of the data. Once all of the data was compiled, it …

The Effects Of Phosphate On The Metamorphosis Of Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), Alexis Jean Polivanov

Department of Environmental Studies: Undergraduate Student Theses

This investigation will collect data to assist in determining if elevated aquatic phosphate levels affects the metamorphosis rate of larval western barred tiger salamanders (Ambystoma mavortium). Monoammonium phosphate fertilizers are being used on crops in Nebraska (NDA, 2017). This area lines up with the area the western barred tiger salamanders are disappearing from (Damme, 2018). Monoammonium phosphate is made up of nitrogen and phosphate. There have been several studies showing how nitrogen is harmful to amphibians such as this salamander (Griffis-Kyle, 2007) (Griffis-Kyle & Richtie, 2007), but there have not been many showing how phosphate affects amphibian’s metamorphosis …

Diet Composition And Analysis Of Fish Species Consumed By The Eurasian Otter In A Marine/Costal Environment, Alexandrea Otto

Department of Environmental Studies: Undergraduate Student Theses

Understanding prey preference in Eurasian otters, Lutra lutra, is important to provide greater insight into aquatic predator-prey relationships which will inform conservation efforts. Identifying the composition of an organism’s diet is one of the primary steps in understanding an organism and developing effective conservation strategies. This study expands upon basic identification of consumed items to estimate size of fish eaten by Eurasian otters to provide information on the diet of these important aquatic predators. Many studies on the Eurasian otter have considered diet from river systems, yet less is known of their diet in marine systems. The goal of my …

Using a thorough literature review, a thematic analysis is applied to combine a variety of sources to draw conclusions regarding how death practices are influenced and evolve over time. Environments, broken down into physical geography, religious, social, and political influences, are examined for the United States, Mexico, Japan, The Torajans of Sulawesi, Indonesia, and Tibet. Factors such as religion and culture have been an important component in the development of many societies’ practices revolving around death. The interconnectedness of cultures makes it difficult …

Lincoln, Ne Composting In Restaurants, Brodie Baum

Department of Environmental Studies: Undergraduate Student Theses

This study aimed to investigate restaurants across the city of Lincoln, Nebraska that compost as a way to reduce food waste. Food waste is a growing environmental concern because it leads to climate change, eutrophication and acidification of bodies of water, pollutes the air and more. This study utilized a software program to distribute a survey that restaurants owners/personnel would take. The survey asked a variety of questions that provided information about the restaurants and who runs it. This information allowed us to draw important conclusions. Based on the results of the survey we can begin to speculate about possible …

The Human Dimensions Of Coral Reef Restoration: A Case Study In The Spermonde Islands Of Indonesia, Jessica Vandenberg

Open Access Dissertations

This study employs a decolonial multidisciplinary approach to explore the sociocultural dimensions of a corporate-led coral reef restoration program implemented in a small island community in Indonesia framed as a conservation and food security initiative. Coral Reef Restoration (CRR) has gained increased attention as a coral conservation tool to supplement traditional approaches to tropical marine management (Boström-Einarsson et al. 2020). Like many other forms of conservation, CRR programs are often posed as dual conservation and development programs, aimed at achieving both ecological and social outcomes. Despite the intention to meet both conservation and development goals, CRR studies have been criticized …

Evaluation Of A Photograph-Based Citizen Science Program As A Tick Surveillance And Prevention Education Tool, Heather Lynn Kopsco

Open Access Dissertations

The multitude of factors fueling the escalation in tick-borne disease in the United States is further complicated by gaps in public knowledge and inconsistent adherence to tick-bite prevention behaviors. Passive tick surveillance is a growing strategy to monitor tick species trends and associated pathogen prevalence across the country. Most practice involves citizens shipping encountered ticks to a laboratory for identification and pathogen testing, but given potential delays in mailing and processing time, tick bite victims may be placed outside the window of potential prophylactic options, or under unnecessary antibiotic administration. Recently, photographed-based tick surveillance has been shown to be a …

Evolutionary History Of Subterranean Termites In The Geographic And Ecological Context Of The Appalachian Mountains In The United States, Chaz Hyseni

Electronic Theses and Dissertations

Termites in the genus Reticulitermes (Blattodea: Rhinotermitidae) are distributed across the eastern United States, including the southern Appalachian Mountains, a region incredibly rich in biodiversity. The eastern subterranean termite, Reticulitermes flavipes, has been uninentionally introduced to South America and Europe, and is predicted to further expand its geographic range. My goal was to determine how eco-evolutionary processes, operating at both long and short timescales, may have contributed to R. flavipes becoming an invasive species. I examined geographic and environmental influences at historical and contemporary timescales. To do this, I first determined the extent of niche divergence among three geographically overlapping …

The Wall We Need: The Necessity For Judicial Hostility Towards Religion And Mistakes Made By The Supreme Court Regarding The Separation Of Church And State, Darin King

CGU Theses & Dissertations

In 1952, in a case held to permit early release of students from school in order to attend religious study off campus, the Supreme Court of the United States declared that, “[W]e find no Constitutional requirement which makes it necessary for government to be hostile to religion.” This Thesis argues the opposite: that government hostility towards religion is, in fact, necessary, both Constitutionally and for prudence’s sake.

Since 2019, Covid-19 has become a common problem affecting all mankind. The disease has successfully spread all over the world. Wearing a mask can practically protect the infection. Thus, detecting people wearing and not wearing masks in public is essential. However, there is still some room to improve detection accuracy of the present methods. In this paper, the transfer learning model and FR-TSVM model are used to study the latest data of pneumonia epidemic situation in Covid-19. First, a data set of 11600 facial images wearing masks and not wearing masks in public was collected for training, testing, and validation. …

Pharmacokinetics, Pharmacodynamics And Dosing Regimen Of Long-Acting Oxytetracycline In Nile Tilapia (Oreochromis Niloticus), Kananuch Vasuntrarak

Chulalongkorn University Theses and Dissertations (Chula ETD)

Antimicrobial resistance has become a serious global problem and is steadily increasing worldwide. In aquaculture, there are limited antimicrobial options for treatment. Thus, there are growing needs for more specific dosing regimens of existing antimicrobial drugs that are not only to obtain therapeutic efficacy but also to minimize the resistance of pathogens. The purposes of this study were to determine pharmacokinetics (PK) of long-acting oxytetracycline (OTC) after intraperitoneal (IP) administration in Nile tilapia. One hundred and twenty healthy male tilapia (450±37.47 g) were divided into two experimental groups (60 fish/group). Each group received OTC-LA single IP injection at dosage of …

Osteogenic Differentiation Potential By Mouse Bone Marrow-Derived Mesenchymal Stemcells (Mbm-Mscs) Derived From Gut Leak-Induced Diabetes Type Ii Mouse Model, Nabila Syarifah Jamilah

Chulalongkorn University Theses and Dissertations (Chula ETD)

Diabetes type II were known to affect several organs in the body including bone, thus diabetes type II patients have higher risk of bone fracture. One of the important features in diabetes type II is low level of anti-inflammatory cytokine Interleukin-10 (IL-10) and gut leak condition. Both of these conditions have the role in diabetes induction, progression and exacerbation. Autogenous Mesenchymal stem cells (MSCs) have been widely utilized for enhancing bone healing treatment. Due to the diabetes condition affecting one of the most common and widely used MSCs source, the bone, this study was done to investigate the effect of …

Winter Patch Grazing, Patch Burn Grazing, And Bird Communities In Western South Dakota, Jennifer Lutze

Electronic Theses and Dissertations

Ground nesting bird species are on a considerable decline and research efforts are being made to increase these populations throughout the Great Plains. Ground nesting bird communities found in the Northern Great Plains are driven greatly by varying amounts of cover and area size. Past research implemented patch-burn grazing to increase structural heterogeneity and to increase grassland bird habitat in the tallgrass prairie. While bird populations were very responsive to this management in the Northern Great Plains fire management is viewed negatively, especially for Midwest cattle ranchers. We implemented research to determine if winter-patch grazing on mixed grass prairie could …
