The Effects Of Late Gestation Supplementation Of Rumen Protected Fat On Cow And Calf Serum Fatty Acids, Passive Immunity Transfer And Growth In Beef Calves, Ralph Earl Ricks

All Theses

The primary objective of the cow calf sector of the beef industry is to market live calves after weaning. One component to profitability in this sector is to wean healthy, productive calves with as low of an input a possible. This means not only efficiency of preweaning growth of the calf, but the dam needs to produce a more than adequate supply of milk as it is the primary nutrition of the calf. Production of an animal that can convert the milk supply offered and turn it into pounds of gain efficiently is ideal. The calf, ideally, should be born …

Vulnerability Of Tri-Colored Bats (Perimyotis Subflavus) To White-Nose Syndrome In The Southeastern United States, Pallavi Sirajuddin

All Theses

Tri-colored bats (Perimyotis subflavus) have experienced significant population declines in the southeastern United States due to white-nose syndrome (WNS). The lack of information on the torpor patterns and winter activity in conjunction with the rapid decline from the disease has led to an increased effort in researching the hibernation physiology and wintering activity of P. subflavus and their response to WNS in southern hibernacula. To address this growing concern, we used temperature sensitive radio transmitters to examine torpor patterns in three geographically distinct states and acoustic detectors to monitor bat activity within a WNS-positive hibernaculum. Our specific objectives …

High-Throughput Polygenic Biomarker Discovery Using Condition-Specific Gene Coexpression Networks, William Louis Poehlman

All Dissertations

Biomarkers can be described as molecular signatures that are associated with a trait or disease. RNA expression data facilitates discovery of biomarkers underlying complex phenotypes because it can capture dynamic biochemical processes that are regulated in tissue-specific and time-specific manners. Gene Coexpression Network (GCN) analysis is a method that utilizes RNA expression data to identify binary gene relationships across experimental conditions. Using a novel GCN construction algorithm, Knowledge Independent Network Construction (KINC), I provide evidence for novel polygenic biomarkers in both plant and animal use cases.

Development Of A Biomimetic, Collagen-Based Scaffold For The Repair And Regeneration Of The Annulus Fibrosus, Ryan Borem

All Dissertations

Annually, over 5.7 million Americans are diagnosed with two IVD-associated pathologies: IVD herniation (IVDH- a mechanical disruption of the concentric fibrous layers of the annulus fibrosus (AF)) and/or degeneration (IVDD- a multifactorial process which initiates within the inner gelatinous core (NP), and results in a biochemical degradation of NP tissue), with over 2.7 million requiring surgical interventions. Although both underlying pathologies are different, quite often they both lead to a decrease in IVD height, impaired mechanical function, and increased pain and disability. These pain symptoms affect approximately 80% of the adult population during their lifetime with estimated expenditures exceeding $85.9 …

Systems To Attract And Feed Pollinators In Warm-Season Lawns, Michelle Wisdom

Graduate Theses and Dissertations

Pollinating insects are responsible for the production of many agricultural crops and they require floral resources to fulfill their life-cycle. Ideally, pollinating insects will encounter a diversity of floral resources across their entire season of activity, and those floral resources can include both herbaceous and woody plant species. Managed turfgrass areas have been identified as potential locations for creating pollinator-friendly habitats. In the transition zone, where both warm- and cool-season turfgrass species are present, the persistence of herbaceous plants in warm-season turfgrasses such as bermudagrass (Cynodon spp.) and buffalograss (Buchloe dactyloides), may be affected not only by the competitive nature …

Comparison Of Northern Flying And Red Squirrel Phylogenies With Focus On The Insular United States, Alyssa M. Kiesow, Hugh B. Britten

The Prairie Naturalist

Northern flying squirrel (Glaucomys sabrinus) and red squirrel (Tamiasciurus hudsonicus) populations are endemic to northern North America, including the Black Hills. The Black Hills populations are considered disjunct from other populations within their range. We examined insular populations to determine whether arboreal squirrels in the Black Hills each represent a unique population. We trapped and collected ear samples from northern flying and red squirrels in the Black Hills and in areas of Montana, Wyoming, Idaho, Utah, Minnesota, and Wisconsin to infer population phylogenies with special consideration of the Black Hills population. Microsatellite loci and two mtDNA sequences were used for …

Metabolic Gas Emissions From Prairie Soil Containing Foraging Termites, Charles E. Konemann, B.M. Kard, Tom A. Royer, Mark E. Payton

The Prairie Naturalist

Differences in subterranean termite metabolic gas emissions are readily observed in laboratory experiments. However, in natural field ecosystems a primary difficulty in measuring subterranean termite gases is non-homogeneous distribution of foraging termites in soil. Our field experiment was designed to aggregate foragers of the 'eastern subterranean termite', Reticulitermes flavipes Kollar (EST), in one of four flux chamber configurations placed on a tallgrass prairie throughout 2014 and 2015. We used differently configured flux chambers to measure metabolic gas emissions from soil with or without foraging termites on The Joseph H. Williams Tallgrass Prairie Preserve (TGPP) in north-central Oklahoma. Foraging termitesaggregated in …

Halted Innovation: The Expansion Of Federal Jurisdiction Over Medicine And The Human Body, Myrisha S. Lewis

Faculty Publications

Modern medical innovations are blurring the line between medical practice and medical devices and drugs. Historically, many techniques have been developed in medicine, without any interference from the federal government, as medical practice is (and has historically been) an area of state jurisdiction. Over the past two decades, however, the U.S. Food and Drug Administration (FDA) has been exerting jurisdiction over the human body and the practice of medicine by targeting new medical techniques for oversight and subjecting the continued use of those treatments to onerous and legally questionable regulatory requirements that hinder the use of those treatments in practice. …

Use Of A Daily Behavior Report Card And Response Dependent Fading To Increase And Maintain Academic Engagement In An Elementary Student With Developmental Delay, Ziyad Alrumayh

Electronic Theses and Dissertations

The initial and maintenance effects of a Daily Behavior Report Card (DBRC) intervention and fading procedure on Academic Engaged Time (AET) of a 6-year-old boy with Developmental Delay and Attention Deficits were evaluated with a reversal design. Following an initial baseline, the DBRC was implemented and then completely removed followed by reapplication of the DBRC. Subsequently, the report card was gradually reduced in the frequency of its use from very daily to every other day. Increased AET reliably varied with the application and then removal of the DBRC. Whereas complete removal of the DBRC resulted in substantial decreases in AET, …

Temperature And Polyunsaturated Fatty Acid’S Effect On Daphnia Magna Reproduction, Mark Albright

Electronic Theses and Dissertations

Organisms adapt to their environments by adjusting their biochemistry and physiology; such adaptation is limited by resource availability and physiological constraints. The freshwater crustacean Daphnia magna inhabits a wide range of environments and must survive and reproduce within a range of temperatures. One limit to low-temperature adaptation is thought to be the availability of unsaturated fatty acids necessary to maintain proper fluidity of cellular membranes. D. magna maintained at 10 ºC on a diet poor in unsaturated fatty acids have been observed to produce clutches that fail to develop. However, this has not been observed on a diet rich in …

The Ecology Of Fecal Indicators, Dennis A. Gilfillan

Electronic Theses and Dissertations

Animal and human wastes introduce pathogens into rivers and streams, creating human health and economic burdens. While direct monitoring for pathogens is possible, it is impractical due to the sporadic distribution of pathogens, cost to identify, and health risks to laboratory workers. To overcome these issues, fecal indicator organisms are used to estimate the presence of pathogens. Although fecal indicators generally protect public health, they fall short in their utility because of difficulties in public health risk characterization, inconsistent correlations with pathogens, weak source identification, and their potential to persist in environments with no point sources of fecal pollution. This …

Co-Infection Of Zika And Dengue Virus In Aedes Aegypti And Aedes Albopictus Mosquitoes, Felicia Vazquez

Theses and Dissertations

The term co-infection describes an event when multiple pathogens infect a single host. For vector-borne diseases, a vector may become co-infected by feeding either on a single host that has multiple pathogens or feeding multiple hosts, each of which may be infected. Co-infection in non-vector hosts has been shown to influence immune response and eventual outcome of disease, and is likely to have a similar impact on vector species. With multiple vector-borne diseases circulating in South Texas, the potential for co-infection exists. We examined when mosquitoes are infected with one virus and subsequently infected with another. We hypothesized that the …

In Vivo Characterization Of Connective Tissue Remodeling Using Infrared Photoacoustic Spectra, Yuan Qu, Peng Hu, Junhui Shi, Konstantin Maslov, Peinan Zhao, Chiye Li, Jun Ma, Alejandro Garcia-Uribe, Karen Meyers, Emily Diveley, Stephanie Pizzella, Lisa Muench, Nina Punyamurthy, Naomi Goldstein, Oji Onwumere, Mariana Alisio, Kaytelyn Meyenburg, Jennifer Maynard, Kristi Helm, Emma Altieri, Janessia Slaughter, Sabrina Barber, Tracy Burger, Christine Kramer, Jessica Chubiz, Monica Anderson, Ronald Mccarthy, Sarah K England, George A Macones, Molly J Stout, Methodius Tuuli, Lihong V Wang

Open Access Publications

Premature cervical remodeling is a critical precursor of spontaneous preterm birth, and the remodeling process is characterized by an increase in tissue hydration. Nevertheless, current clinical measurements of cervical remodeling are subjective and detect only late events, such as cervical effacement and dilation. Here, we present a photoacoustic endoscope that can quantify tissue hydration by measuring near-infrared cervical spectra. We quantify the water contents of tissue-mimicking hydrogel phantoms as an analog of cervical connective tissue. Applying this method to pregnant women in vivo, we observed an increase in the water content of the cervix throughout pregnancy. The application of this …

On Affect: Function And Phenomenology, Andreas Elpidorou

Faculty and Staff Scholarship

This paper explores the nature of emotions by considering what appear to be two differing, perhaps even conflicting, approaches to affectivity—an evolutionary functional account, on the one hand, and a phenomenological view, on the other. The paper argues for the centrality of the notion of function in both approaches, articulates key differences between them, and attempts to understand how such differences can be overcome.

Cold Acclimation Response Of Non-Native Italian Wall Lizard (Podarcis Siculus) Populations From New York And California, Daniel Haro

Master's Theses

Understanding how organisms respond to climatic variability and novel conditions is becoming an increasingly important task for ecologists. For ectotherms in the northern hemisphere, the response to cold is of special interest, considering that poleward range expansion events and increasing variability of temperatures during winter are already being observed as consequences of a warming planet. Though direction of change in physiological variables in response to cold is well studied in ectotherms, the extent to which traits can change and the rate at which they can change is not.

We compared the extent and rate of change in cold tolerance (CT …

Cleaver: Classification Of Everyday Activities Via Ensemble Recognizers, Samantha Hsu

Master's Theses

Physical activity can have immediate and long-term benefits on health and reduce the risk for chronic diseases. Valid measures of physical activity are needed in order to improve our understanding of the exact relationship between physical activity and health. Activity monitors have become a standard for measuring physical activity; accelerometers in particular are widely used in research and consumer products because they are objective, inexpensive, and practical. Previous studies have experimented with different monitor placements and classification methods. However, the majority of these methods were developed using data collected in controlled, laboratory-based settings, which is not reliably representative of real …

Comparative Analysis Of Electrodynamic Toroidal Radiation Shielding Configurations, Max Rosenberg

Master's Theses

Beyond the protective confines of Earth's atmosphere and magnetosphere, spacecraft are subject to constant bombardment by high-energy charged particles originating from our Sun in the form of Solar Particle Events (SPEs), and from outside the solar system in the form of Galactic Cosmic Rays (GCRs). The harm these particles do can be reduced or mitigated outright through radiation shielding. Because protons and other charged particles comprise most of these radiation particles, strong magnetic fields could be generated around spacecraft to deflect incoming charged radiation particles. This thesis investigates the performance of specific configurations of toroidal superconducting solenoids to generate magnetic …

A Computational Fluid Dynamics (Cfd) Analysis Of The Aerodynamic Effects Of The Seams On A Two-Dimensional Representation Of A Soccer Ball, Allen R. Rohr

Master's Theses

Most major sports today use a dedicated ball or projectile with specific shape, size, and surface geometry, except for soccer. Over the history of the sport, the surface geometry and design stayed relatively unchanged, sewn together using 32 pentagonal and hexagonal panels. However, recent innovations in panel designs differ substantially from the traditional 32 panel ball. The effects these new designs have on the aerodynamic characteristics of the ball have remained largely unknown, even with the influx of experimental research completed in the past decade. Experimental studies have been broad in scope, analyzing an entire ball in wind tunnels or …

A Carrier-Pigeon Uas For South Pole Data Transfer, Shaun P. Wixted

Master's Theses

The assessment of feasibility of an Unmanned Aircraft System (UAS) that is specifically tailored—in performance, operating and support characteristics, and payload—to support hardware-based data transfer from South Pole Station in Antarctica to a location of high connectivity has been undertaken. Due to the specific location of the Amundsen-Scott South Pole station and competing demands from other governmental agencies, satellite connectivity requirements for data transfers cannot be met at the South Pole. In the recent decades, the advancement in UAS capabilities have overwhelming extended their operational reach in military and commercial reconnaissance and surveillance missions. This UAS has the potential to …

The Thermal Ecology Of Sceloporus Occidentalis, Luis Patricio Burgos

Master's Theses

With temperatures rising globally, assessing the possible impacts of the changing climate becomes more and more urgent. Ectotherms are excellent indicators of potential climatic ramifications on biodiversity because of their heavy reliance on the environment for their thermoregulation. Studies have historically looked at thermal tolerance values to establish predictive models for population and species extinctions.

In chapter 1, we looked at recent studies that suggest that thermal tolerance may be a plastic trait and test the effects empirically. Most studies are based on captive lizards acclimated to laboratory conditions that do not necessarily reflect natural environments, and if thermal tolerance …

Comparative Transcriptomic Analysis Of Developmental Stages In Isolated Mammary Epithelial Cells, Nicole K. Einfalt

Master's Theses

The mammary gland is an organ common to all mammals; it is of value for neonatal nourishment, human nutrition through dairy consumption, and is a source of pathology in humans through the development of breast cancer. While transcriptomic analyses have been applied to cultured mammary epithelial cells (MEC) and to whole gland samples, few have studied purified MEC isolated directly from the gland in vivo. To identify the differentially expressed genes influencing MEC development during pregnancy and the differences between the nulliparous and primiparous quiescent states, primary MEC were isolated from virgin, pregnant, and primiparous quiescent sibling mice. Computational …

Conceptual Metaphors For "Refugees" In Online Newspapers: An Empirical Study In German And In Thai(Konzeptuelle Metaphern Zum Begriff „Flüchtlinge" In Online-Zeitungen: Eine Empirische Studie Im Deutschen Und Im Thai), Phongsakorn Jamjumrus

Journal of Letters

This research article investigates the comparative language usage of refugee metaphors in German and Thai in two selected online newspapers: Süddeutsche Zeitung and Thairath. According to Lakoff and Johnson's (1980) cognitive theory of the conceptual metaphor, metaphors exert a major influence on our thinking, perceptions and behaviour in everyday life. This study uses both quantitative and qualitative methods to analyze data from a German and a Thai corpus. It was found that twelve source domains are used in German and Thai data. In both corpora, refugees were represented in six domains, namely as GOODS, ENEMIES, WATER, OBJECTS, GUESTS/VISITORS and VEHICLES. …

This includes using novel feed ingredients to reduce cost and improve animal health, genetic selection for increased performance, and vaccines to attenuate or prevent illness. Research plays a significant role in assessing the effectiveness of these strategies. Overall, the objective of this thesis was to assess how genetic selection, vaccines, and feed additives may impact growth performance, health, nutrient digestibility, and the microbiome.

In Chapter 2, pigs were either …

Impact Of Ethanol Process Changes On Distillers’ Grains For Beef Cattle, Shelby A. Garland

Department of Animal Science: Dissertations, Theses, and Student Research

Distillers grains plus solubles (DGS) have been widely utilized in beef cattle diets. Fractionation of the corn kernel pre- and post-fermentation has changed the composition of DGS and allowed for the production of other feed byproducts over time. The use of fractionated DGS and other feed byproducts from the ethanol industry has not been heavily researched in beef cattle diets. Three experiments were conducted to evaluate the effect of feeding high protein distillers grains (HiPro DDG) and corn bran plus solubles (Bran + Solubles) in beef cattle diets. Experiment 1 evaluated the effect of byproduct type on finishing performance and …
