Enhancing The Industrial Potential Of Filamentous Cyanobacteria, Tylor J. Johnson

Electronic Theses and Dissertations

The objectives of this project were to improve the industrial potential of filamentous N2-fixing cyanobacteria by increasing its biofuel tolerance, and to evaluate the economic feasibility and environmental impacts of a theoretical, cyanobacteria-based biofuel production facility. To develop a method to quantify filamentous cyanobacteria in dilute culture media, a dual-stained fluorescence assay was evaluated. While the viable cell stain (SYTO® 9) was accurate, the non-viable cell stain (propidium iodide) also bound to viable cells. Additional non-viable cell stains were evaluated, but none were accurate at quantifying viability. Thus we concluded that the viable cell stain SYTO® 9 is a reliable …

Restoration Of Eroded Lands With Biochar As Soil Amendment In South Dakota, Saroop S. Sandhu

Electronic Theses and Dissertations

Biochar is produced from incomplete pyrolysis of plant biomass. Due to the unique properties of biochar such as a higher number of micropores, surface area and carbon content, and recalcitrant nature of carbon, biochar is hypothesized to improve physical and hydrological properties of soil. This study assesses the impact of biochar on soil organic carbon, physical and hydrological properties of two landscape positions under a corn (Zea mays L.)-soybean (Glycine max L.) rotation. Three types of biochar including corn stover, ponderosa pine (Pinus ponderosa Lawson and C. Lawson) wood residue, and switchgrass (Panicum virgatum L.) were applied in the field …

Improving Feed Efficiency Through Forage Strategies For Increasing Dairy Profitability And Sustainability, Jon Patrick Pretz

Electronic Theses and Dissertations

Three studies were conducted to determine production parameters and study specific hypothesis in regard to improving feed efficiency through various forage utilization strategies with or without the inclusion of various supplemented products. The first study evaluated the supplementation of a cobalt-lactate product and its effects on fiber digestibility and milk production parameters when fed to cows consuming a 70% forage diet. Treatments included: 1) CONTROL diet containing 12.5 mg/cow/d of cobalt (carbonate carbonate) and 2) TEST diet being the same basal diet but including an additional 50 mg/cow/d of cobalt via a 1% Co-lactate product (Co-Max®). In a feeding trial …

Diversity Of Free-Living Nitrogen Fixing Bacteria In The Badlands Of South Dakota, Bibha Dahal

Electronic Theses and Dissertations

Biological Nitrogen Fixation is carried out by a highly diverse group of members of the domains Bacteria and Archaea which express a nitrogenase enzyme complex and are termed diazotrophs. The best known diazotrophs form symbiotic associations with plants, but free-living nitrogen fixing bacteria also contribute a substantial amount of nitrogen to ecosystems, including arid lands. The aim of this study was to isolate free-living diazotrophs from the soil crusts of sod tables of South Dakota Badlands. Samples were obtained from sod tables and the surrounding base (matrix) in spring and fall of 2014. A culture dependent approach was used to …

An Analysis Of The Demand For Rail Transportation Of Corn, Soybeans, And Wheat In South Dakota, Melinda Sommer

Electronic Theses and Dissertations

The cropping patterns, grain marketing flows, and transportation needs have changed in South Dakota as increased ethanol production has led to a significant increase in corn production and the production of distiller’s dried grains with solubles (DDGS) as a co-product. Previous studies have not focused specifically on the grain and oilseed transportation needs in South Dakota over an extended period of time that covers the influence of ethanol production. Quarterly rail data from the Surface Transportation Board Public Use Waybill Sample for 1991 to 2013 were used in a regression analysis of the demand for rail transportation of corn, soybeans, …

Using Remote Sensing And Biogeographic Modeling To Understand The Oak Savannas Of The Sheyenne National Grassland, North Dakota, Usa, Mandira Sigdelphuyal

Electronic Theses and Dissertations

Oak savannas are valuable and complex ecosystems that provide multiple ecosystem goods and services, including grazing for livestock, watershed regulation, and recreation. These ecosystems of the woodland-prairie ecoregion of the Midwestern United States are, however, in danger of disappearing. The Sheyenne National Grassland, North Dakota, a protected Prairie grassland-savanna, is a representative of such rare habitats, where oak savanna is found at the landscape scale. In this research, I map the distribution patterns of oak savanna in the Sheyenne using a combination of remote sensing and geospatial datasets, including landscape topography, soils, and fire disturbance. Further, I interpret the performance …

The Biosemiotics Of Aldo Leopold, Rebecca Potter

English Faculty Publications

Responding to Jean-Claude Gens’ article “Uexküll’s Kompositionslehre and Leopold’s ‘land ethic’ in dialogue,” which appeared in Sign Systems Studies in 2013, this article further develops a direct connection between Aldo Leopold’s approach to ecology and Jakob von Uexküll’s umwelt theory. The connection between Uexküll and Leopold is especially evident in Leopold’s descriptions of animal behaviour that he presents in the first part of his seminal work, A Sand County Almanac. In this work specifically, Leopold illustrates the biosemiotic processes described by Uexküll, and does so with a purpose: to reshape our understanding of the biotic community as a place …

Entrevistas A María Reimóndez, Rosa Montero Y Julia Otxoa: El Arte De La Escritura Y El Activismo, Estrella Cibreiro

Spanish Department Faculty Scholarship

Writings by Spanish contemporary authors María Reimóndez, Rosa Montero, and Julia Otxoa display, not only a deep awareness of local and national matters, but also a noteworthy engagement with broader issues of a global nature. Their works highlight, furthermore, the diversity of female voices in Spanish literature as well as the pluralism of languages, cultures, and geographies that make up the Iberian Peninsula today. This article provides a brief description of this research project as a whole, a concise critical introduction to each of the author’s works, and interviews with the three writers. The introduction to María Reimóndez’s work focuses …

3d Digital Technologies To Record Excavation Data: The Case Of The Catacombs Of St. Lucy (Siracusa, Sicily), Davide Tanasi, Ilenia Gradante, Mariarita Sgarlata

History Faculty Publications

Between 2013 and 2015, Arcadia University in partnership with the Pontifical Commission for Sacred Archaeology and the University of Catania undertook new excavation campaigns in the Catacombs of St. Lucy at Siracusa. The research focuses on some very problematic parts of Region C of the complex, including Oratory C, the so-called Pagan Shrine and Crypt VI. These areas document most effectively the long life of this Christian hypogeum, which incorporated previous structures and artefacts related to the Greek period and continued to be used until the Middle Ages. During the excavation an array of 3D digital techniques (3D scanning, 3d …

Rediscovering The Maltese Temple Of Borġ In-Nadur: An Archaeoastronomical Perspective, David Tanasi, Andrea Orlando

History Faculty Publications

The Maltese island have megalithic temples of extraordinary interest for archaeoastronomy. In literature we find different works that involve most of its archaeological sites. The temple of Borġ in-Nadur, set on the top of a hill by the Marsaxlokk Bay in southern Malta, is less well known than the rest of the others, even though it started off as a major attraction for grand tourists and travellers in the Early Modern and Colonial periods. It was explored in the second half of the 1920s by a team of British archaeologists, led by Margaret Murray, who gradually uncovered the ruins of …

Migration, Labor Scarcity, And Deforestation In Honduran Cattle Country, David C. Griffith, Raquel Isaula, Pedro Torres, Manuel Villa Cruz

Journal of Ecological Anthropology

Large scale labor migration from Olancho, Honduras to the United States, accelerated after 1998, when Hurricane Mitch devastated the region and resulted in the United States offering Temporary Protective Status (TPS) to affected Hondurans. As growing numbers left for the United States, the loss of productive youth to migration and the development of new local economic opportunities combined to create shortages of labor available for traditional uses of local natural resources in rural communities. Remittances from abroad and sentimental factors also contributed to the erosion of local labor supplies, leading some rural producers to phase back on mixed crop-and-livestock strategies …

Strategic Rulemaking Disclosure, Jennifer Nou, Edward Stiglitz

Coase-Sandor Institute for Law & Economics Research Paper Series

Congressional enactments and executive orders instruct agencies to publish their anticipated rules in what is known as the Unified Agenda. The Agenda’s stated purpose is to ensure that political actors can monitor regulatory development. Agencies have come under fire in recent years, however, for conspicuous omissions and irregularities. Critics allege that agencies hide their regulations from the public strategically, that is, to thwart potential political opposition. Others contend that such behavior is benign, perhaps the inevitable result of changing internal priorities or unforeseen events.

To examine these competing hypotheses, this Article uses a new dataset spanning over thirty years of …

The Role Of Individual Variation In Auditory And Visual Processing: Implications For Mate Choice, Kelly Ronald

Open Access Dissertations

Intersexual interactions often include a dynamic exchange of courtship signals in different sensory modalities. My work focuses on understanding the factors that contribute to variation in male sexual signals and variation in female sensory perception and behavioral responses to these signals. I addressed several specific research questions using the brown headed cowbird (Molothrus ater) as a model species: (i) how does male signaling behavior differ with the sex of the receiver? (ii) how do components within a signal combine to generate a response by the female, (iii) how is female sensory capacity in one modality related to her sensory capacity …

Aging Dysregulates D- And E-Series Resolvins To Modulate Cardiosplenic And Cardiorenal Network Following Myocardial Infarction, Ganesh V. Halade, Vasundhara Kain, Laurence M. Black, Sumanth D. Prabhu, Kevin A. Ingle

Internal Medicine Faculty Publications

Post-myocardial infarction (MI), overactive inflammation is the hallmark of aging, however, the mechanism is unclear. We hypothesized that excess influx of omega 6 fatty acids may impair resolution, thus impacting the cardiosplenic and cardiorenal network post-MI. Young and aging mice were fed on standard lab chow (LC) and excess fatty acid (safflower oil; SO)-enriched diet for 2 months and were then subjected to MI surgery. Despite similar infarct areas and left ventricle (LV) dysfunction post-MI, splenic mass spectrometry data revealed higher levels of arachidonic acid (AA) derived pro-inflammatory metabolites in young-SO, but minimal formation of docosanoids, D- and E- series …

Bortezomib-Induced Complete Heart Block And Myocardial Scar: The Potential Role Of Cardiac Biomarkers In Monitoring Cardiotoxicity, Sachin Diwadkar, Aarti A. Patel, Michael G. Fradley

Internal Medicine Faculty Publications

Bortezomib is a proteasome inhibitor used to treat multiple myeloma and mantle cell lymphoma. Traditionally, bortezomib was thought to have little cardiovascular toxicity; however, there is increasing evidence that bortezomib can lead to cardiac complications including left ventricular dysfunction and atrioventricular block. We present the case of a 66-year-old man with multiple myeloma and persistent asymptomatic elevations of cardiac biomarkers who developed complete heart block and evidence of myocardial scar after his eighth cycle of bortezomib, requiring permanent pacemaker placement. In addition to discussing the cardiovascular complications of bortezomib therapy, we propose a potential role for biomarkers in the prediction …

Effects Of Wind Energy Generation And White-Nose Syndrome On The Viability Of The Indiana Bat, Richard A. Erickson, Wayne E. Thogmartin, Jay E. Diffendorfer

KIP Articles

Wind energy generation holds the potential to adversely affect wildlife populations. Species-wide effects are difficult to study and few, if any, studies examine effects of wind energy generation on any species across its entire range. One species that may be affected by wind energy generation is the endangered Indiana bat (Myotis sodalis), which is found in the eastern and midwestern United States. In addition to mortality from wind energy generation, the species also faces range-wide threats from the emerging infectious fungal disease, white-nose syndrome (WNS). White-nose syndrome, caused by Pseudogymnoascus destructans, disturbs hibernating bats leading to high levels of mortality. …

Using A Novel Partitivirus In Pseudogymnoascus Destructans To Understand The Epidemiology Of White-Nose Syndrome, Vaskar Thapa, Gregory G. Turner, Susan Hafenstein

KIP Articles

White-nose syndrome is one of the most lethal wildlife diseases, killing over 5 million North American bats since it was first reported in 2006. The causal agent of the disease is a psychrophilic filamentous fungus, Pseudogymnoascus destructans. The fungus is widely distributed in North America and Europe and has recently been found in some parts of Asia, but interestingly, no mass mortality is observed in European or Asian bats. Here we report a novel double-stranded RNA virus found in North American isolates of the fungus and show that the virus can be used as a tool to study the epidemiology …

On Migrant Workers’ Social Status In Taiwan: A Critical Analysis Of Mainstream News Discourse, Hsin-I Cheng

Communication

It is estimated that around 20 million Southeast Asians work outside of their home country. In 1991, Taiwan first introduced about 3,000 migrant workers from Thailand. In mid-2015, there were approximately 579,000 migrant workers who came under the category of foreign laborers mainly from Southeast Asia. However, there is scarce research on representations of the south–south international migration. This study critically analyzes mainstream news discourse on migrant workers in Taiwan to discern their relations to their residing society. Four themes emerged: objectification of foreign laborers; differentiated and gendered marginalization; multilevel triangulations over migrant bodies; and imperialistic cultural attitudes toward migrant …
