Technology-Intensive Exports, R&D, Human Capital, And Economic Growth In The Twenty-First Century, Pierce Plucker
Electronic Theses and Dissertations
This thesis investigates twenty-first century economic growth through a distanceto- frontier (technology-gap) lens where growth in a country’s knowledge stock is determined by knowledge creation and knowledge imitation. The creation term is assumed to be a function of research and development, technology-intensive export performance, and human capital, while the imitation term is a function of the technology gap, technology-intensive export performance, and human capital. Over the period 1997-2018, two samples of countries are analyzed in a panel setting, and two growth models are estimated in total—one for each sample. While research and development has been extensively analyzed in the economic …

Deforming The Knight: Gawain's Descent Into Monstrosity In Sir Gawain And The Green Knight, Hannah Held
Deforming The Knight: Gawain's Descent Into Monstrosity In Sir Gawain And The Green Knight, Hannah Held
Electronic Theses and Dissertations
Sir Gawain has always been marked as a victim in the well-known poem Sir Gawain and the Green Knight, but he is much more than that. Standing with the knights of the Round Table, he seems to be the perfect example of what chivalry should look like, especially with an adherence to the common religious beliefs. However, when put into the context of the manuscript in which it was found, Gawain seems to stand as an allegorical figure of the do-not’s of feudal and religious chivalry. Using the lens of Monster Theory via Jeffrey Jerome Cohen and David Williams, I …

Micellar casein concentrate (MCC) is a high protein ingredient that can be used in several applications, such as manufacture of acid curd and process cheese products (PCP). Acid curd is one of the casein (CN) products, which can be obtained by precipitating the CN at a pH of 4.6 (isoelectric point) using starter cultures or direct acids. Acid curd has low mineral and calcium content due to the solubility of colloidal calcium phosphate at the isoelectric point in the whey. Acid curd and MCC can be utilized in manufacture of clean label PCP formulations. PCP is a dairy food prepared …
Defining Amino Acid Requirements Of Pregnant Sows: Challenges And Opportunities, Christian D. Ramirez-Camba
Defining Amino Acid Requirements Of Pregnant Sows: Challenges And Opportunities, Christian D. Ramirez-Camba
Electronic Theses and Dissertations
The efficient use of protein in animal production is dependent on the protein supply and its constituent amino acids (AA) in relation to the animal's needs. Excess AA are deaminated, and the resulting nitrogen (N) is excreted, whereas suboptimal AA intake reduces animal performance. Both increased nutrient excretion and decreased animal performance reduce the overall efficiency of the production unit. In sows, AA requirements should be adequate for optimizing reproductive performance, as measured, for example, by the number of pigs produced per sow per year while limiting N excretion. There is a desire to feed pregnant sows AA levels that …
Above-Ground Biomass Estimation In Oat Breeding Nurseries Using Uav-Based Multispectral Data, Rakshya Dhakal
Above-Ground Biomass Estimation In Oat Breeding Nurseries Using Uav-Based Multispectral Data, Rakshya Dhakal
Electronic Theses and Dissertations
Conventional methods of phenotyping for above-ground biomass under field conditions are time consuming, costly, and labor intensive. Unmanned Aerial Vehicles (UAV) offer a rapid and non-destructive approach for collecting high temporal and spatial resolution imagery of multiple field plots. Vegetation indices (VIs) can be derived from those imagery and have been used broadly for high-throughput biomass estimation, however, they suffer from spectrum saturation issues at high canopy density. In addition, VIs only reflect the canopy spectral information and fail to incorporate the 3-dimensional (3D) canopy structure and architecture information. It also ignores the spatial relationship of pixels to each other …

Ceo Types And Firm Efficiency, Lok Chi Lam
Ceo Types And Firm Efficiency, Lok Chi Lam
Electronic Theses and Dissertations
This paper investigates the connection between CEO types and firm efficiency. I utilize the general ability index (GAI) as a proxy to examine and separate CEO types: generalist CEOs and specialist CEOs. Initially, I applied the pooled ordinary least square (OLS) and fixed effect regression on 26,830 firm-year observations to explore the GAI effect on firm efficiency. The finding shows that GAI has a negative impact on firm efficiency. It indicates that CEOs with lower GAI are better at improving firm efficiency; for instance, specialist CEOs are preferable to generalist CEOs. Further analysis of CEO types using the quadrant method …

Identification And Characterization Of Candidate Rumen Bacterial Species From Beef Cattle With The Potential For Metabolizing Lipids, Cheyenne E. Hron
Electronic Theses and Dissertations
Ruminants and the microorganisms within their rumen have an intricate symbiotic relationship. Ruminants are able to convert plant materials that are indigestible to humans into meat, milk, and fiber for human consumption and use. Supplementing lipids in diets fed to beef cattle could be beneficial for the host animal as lipids are a higher density energy source. However, they can be detrimental to rumen microorganisms. While much research has been involved in elucidating the composition of the ruminal microbiome, knowledge of the effects of lipids on the ruminal microbiome has been quite limited. In this context, we took advantage of …

Evaluating Avian Use Of Cover Crops In The Corn Belt, Megan Figura
Electronic Theses and Dissertations
The tallgrass prairie of North America has changed drastically since colonial settlement, with up to 99% of this region converted for agriculture and other land-uses. Concurrent with grassland conversion, grassland birds have experienced the most extreme, consistent, and widespread population declines of any avian guild. Agricultural lands in the U.S. Midwest were able to provide adequate habitat for several bird species until the 1950’s; however, altered and intensified management practices have degraded much of remaining suitable habitat and undermined ecosystem functions. Consequently, many grassland birds have been identified as Species of Greatest Conservation Need (SGCN) in many State Wildlife Action …
Pathogen Prevalence In Domestic Sheep In Western Nebraska: Implications For Bighorn Sheep Conservation And Coexistence On A Multi-Use Landscape, Kaytlin Bohr
Electronic Theses and Dissertations
Bighorn sheep (Ovis canadensis) and domestic sheep (Ovis aries) are members of the same genus and thus share multiple pathogens that can be spread between them. One specific respiratory pathogen of concern is Mycoplasma ovipneumoniae (M. ovipneumoniae), which has been linked to pneumonia epizootics in bighorn sheep that are often characterized by all age die offs upon initial exposure followed by years of low lamb recruitment. Domestic sheep have been identified as one carrier of M. ovipneumoniae with transmission between sheep species occurring when there is close contact on the landscape. To prevent this cross-species transmission, importance has been placed …

Development Of A Chromatographic Method To Authenticate Aspirin Brands, Megan Guetzloff
Development Of A Chromatographic Method To Authenticate Aspirin Brands, Megan Guetzloff
Electronic Theses and Dissertations
Counterfeit pharmaceuticals pose a threat to society that can include inaccurate amounts of the active pharmaceutical ingredient (API), no API, or containing off-target compounds. For example, there are many recent examples of counterfeit pharmaceuticals containing potentially lethal doses (> 2 mg) of fentanyl (i.e., a synthetic opioid). Current measures to combat illicit pharmaceuticals (e.g., unique packaging and product serialization) have merit, however with evolved technologies, counterfeiters can relatively easily simulate these measures and continue to distribute illicit pharmaceuticals. The only accurate way to definitively determine that a suspected counterfeit is, in fact, counterfeit is advanced chemical analysis. However, current methods …

Relative Radiometric Correction Of Pushbroom Satellites Using The Yaw Maneuver, Christopher Begeman
Relative Radiometric Correction Of Pushbroom Satellites Using The Yaw Maneuver, Christopher Begeman
Electronic Theses and Dissertations
Earth imaging satellites commonly acquire multispectral imagery using linear array detectors formatted as a pushbroom scanner. Landsat 8, a well-known example, uses pushbroom scanning and thus has 73,000 individual detectors. These 73,000 detectors are split among 14 different focal plane modules (FPM), and each detector and FPM exhibit unique behavior when monitoring a uniform radiance value. To correct for each detectors differences in sensor measurement a novel technique of relative gain estimation that employs an optimized modified Signal-to-Noise Ratio through a 90˚ yaw maneuver, also known as side slither, is presented that allows for both FPM and detector level relative …

Electronic Theses and Dissertations
Grapevine is one of the most important fruit crops in the world, responsible for billions in global sales annually. The largest threat to grapevine and other crop production is global climate change resulting human activities. This brings unpredictable and drastic changes in ambient air temperatures to many climates in which grapes are grown. Lower temperatures and inclement weather are already responsible for millions in lost revenue due to tissue damage of established plants. Thus, protecting grapevine crops from weather-related damage is the biggest concern to growers aside from pathogen- and diseaserelated crop damage. The primary mechanism for winter survival in …

Polymeric Nanovaccine Delivery System For Influenza Vaccine, Chaitanya K. Valiveti
Electronic Theses and Dissertations
Vaccines are the most efficient and cost-effective method for preventing illnesses caused by infectious pathogens. Even though the great success of vaccines over decades, the development of safe and robust vaccines is still essential for emerging new pathogens, re-evolving old pathogens, and improving the insufficient protection given by existing vaccines. One of the most critical strategies for developing effective new vaccines is selecting and using a suitable adjuvant or immune stimulant. Immunologic adjuvants are essential for improving vaccine potency by enhancing the immune response of vaccine antigens. The amount of antigen could be spared with improved potency, especially during mass …

Managing Water Quantity And Quality With Subsurface Drainage In Eastern South Dakota, Morghan Hurst
Electronic Theses and Dissertations
Moisture extremes (excess and deficit) impact crop loss and water quality. Due to excessively wet springs and dry summers, crop damage can occur within the same county or field within the same year. To determine the magnitude of this problem in eastern South Dakota, indemnified crop insurance data for drought and excessive moisture claims were assessed for the years 1991-2020 for the occurrence of both excess moisture and drought in four counties in eastern South Dakota. Results show that there is greater than a 70% chance of the moisture extremes happening in the same year, making subsurface drainage, controlled drainage, …
Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi
Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi
Electronic Theses and Dissertations
Globally, canola is the second largest oilseed crop after soybean, which is processed for the commercial production of high value oil. The industrial processing steps for canola oil extraction include preprocessing (cleaning, pressing, flaking, and cooking), mechanical pressing, and/or organic solvents. This process results in large quantities of protein-rich (~ 40% dry basis) meal as a co-product. The meal is used partially in animal diet (<30% inclusion) due to high levels of antinutritional factors (ANFs) such as high fibers, phytic acid, and glucosinolates, and low metabolizable energy. Thus, this research was designed to examine various bioprocessing technologies (i.e., traditional sprouting, solid state fermentation, submerged state fermentation, co-culture fermentation, mild pretreatments, and their combinations) for possible advancement in canola use. Canola seed sprouting for 6-day period led to an increase in protein content and a reduction in ANFs and oil content of sprouts compared to ungerminated seed. Subsequent submerged state fermentation of 6- day old sprouts using three different strains (Aureobasidium pullulans, Trichoderma reesei and Neurospora crassa) further increased protein content and lowered ANFs. Solid-state fermentation of 144 h old sprouts using A. pullulans, N. crassa and T. reesei enhanced the protein content and reduced ANFs of sprouts. Sprouting canola seed for three days helped in hull removal, leading to high protein meal accompanied by low fiber and phytic acid level. Three-day seed sprouting had no effect on oil yield, but free fatty acid content was higher compared to seed oil. Co-culture fermentation of HECM under solid state process showed maximum reduction in fiber content with co-culture of A. pullulans and N. crassa while a combination of A. pullulans and T. reesei promoted the highest GLS and phytic acid reductions compared to other combinations, which indicated the advantage of coculture inoculation over monoculture in terms of ANFs reduction. Mild pretreatment of HECM using deionized water resulted in washed HECM (WHECM) with lower soluble sugars and GLS compared to untreated HECM, whereas protein and amino acid were concentrated due to the removal of soluble components. WHECM compared to HECM showed higher protein digestibility when fed to rainbow trout. Subsequent mono- and coculture fermentation of HECM and WHECM under submerged process resulted in higher protein and amino acid content and lower ANFs levels compared to uninoculated controls. The results of cellulase, endoglucanase and β-glucosidase activity indicated the crucial role of used substrates, fungi, fermentation modes (solid state/submerged stated) and inoculation methods (mono-/co-culture) on enzyme activities.
