Investigating Elevated Aqua Modis Aerosol Optical Depth Retrievals Over The Mid-Latitude Southern Oceans, Travis Toth

Theses and Dissertations

A band of elevated aerosol optical depth (AOD) over the mid-latitude Southern Oceans has been identified in some passive satellite-based aerosol datasets such as Moderate Resolution Imaging SpectroRadiometer (MODIS) and Multi-angle Imaging SpectroRadiometer (MISR) products. In this study, Aqua MODIS (AM) aerosol products in this zonal region are investigated in detail to assess retrieval accuracy. This is done through multiple data sets, including spatially and temporally collocated cloud and aerosol products produced by the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) project for investigating AM AOD in this region with respect to lidar profiling of cloud presence. Maritime Aerosol Network (MAN) …

The Effects Of Vibration Exercise On Anaerobic Performance Using The Wingate Test, Daniel Duane Veith

Theses and Dissertations

The aim of this study was to investigate whole-body vibration (WBV) and its effects on anaerobic performance using the Wingate test, specifically the changes in peak and mean power. Thirty five collegiate students completed three days of training in which they performed 3 different weighted exercises under vibratory or non-vibratory conditions. Participants then performed a Wingate. Two 2 x 2 mixed-design ANOVAs were used to examine the influence of the independent variables of sex, protocol, and order on peak and mean power output (SPSS 18.0; p ≤ 0.05). Results indicated a significant main effect of sex in regards to peak …

Factors Impacting Clinical And Counseling Psychology Students Conducting Research With Lgbt Populations, Daniel Walinsky

Theses and Dissertations

Although a large body of literature exists on training clinical and counseling psychology researchers, scant empirical work has been published that looks at the unique needs of students working with lesbian, gay, bisexual, and transgender (LGBT) populations. This study explores researcher development experiences of those students.

Two hypotheses are tested with a sample of 59 doctoral students in APA-accredited clinical and counseling psychology program. The first hypothesis posits that Exploration and Commitment Factors of the Measure of Sexual Identity Exploration and Commitment (MoSIEC) will account for variance on the Research Outcome Expectations Questionnaire (ROEQ) beyond that accounted for by social …

The Study Of Vinyl Ester Copolymers Derived From Bio-Sourced Fatty Acids, Hai Wang

Theses and Dissertations

Biobased polymers have attracted significant attention since the 1990s. Research has focused on the conversion of biomass, such as crop oils, into useful polymeric materials. The Departments of Chemical Engineering and Chemistry at the University of North Dakota have developed a process to convert crop oils into jetfuel and a suite of other chemicals including fatty acids with a variety of molecular weights. This dissertation focuses on the preparation and property measurements of thermoplastics using monomers, especially linear vinyl esters (LVEs), which originate from cracked oil-based fatty acids. Commercial LVEs were used in this dissertation study in order to explore …

Hyperbranched And Polydimethylsiloxane Based Membranes For Co2 Capture, Willie Wesley Wells

Theses and Dissertations

As we continue to come to terms with a warming planet created, in part, by our dependence on fossil fueled power plants, there is a great and urgent need for cost effective methods of isolating and capturing greenhouse gasses. Among the many methods currently being explored for CO2 separation, membranes have proven to be a promising solution. This thesis examines three types of possible membranes: composite layer membranes, hyperbranched membranes and dense film membranes. In addition to examining the permeance of each type, the study explored various membrane formation techniques and how that affects the permeability of specific membrane types. …

A High Energy X-Ray Diffraction Investigation Of Sodium Phosphate Glasses Doped With Less Than 5 Mol% Praseodymium Oxides, Kailing Zhang

Theses and Dissertations

Rare earth phosphate glasses (REPGs) are excellent materials for high energy (103 - 106 J) / high peak power ( 1012 - 1015 W) lasers. Previous work of the rare earth doped sodium phosphate glasses with compositions (R₂O₃)_x(Na₂O)_y(P₂O₅)_1-x-y where R= Nd, Eu and Dy, 0.04 < x < 0.13 showed that the intensity of the emission spectra increases with decreasing R₂O₃ content. In this study, praseodymium doped sodium phosphate glasses with even lower praseodymium oxide concentrations, (Pr₂O₃)_x(Na₂O)_yP₂O₅)_1-x-y , where 0.005 < x < 0.05 were processed and characterized focusing on the region where the lasing efficiency is possibly going to peak. Emission spectra for the glass samples were measured to study how the florescence efficiency change with Pr3+ concentration. High Energy X-ray diffraction technique was used to study the atomic-scale structure of the rare-earth doped sodium phosphate glass samples. Structural features such as inter-atomic distances, coordination numbers and their dependence on the concentration of the rare earth oxides were gained from analyzing pair distribution functions extracted from diffraction data.

An Investigation Of Reflective Mulches For Use Over Capillary Mat Systems For Winter-Time Greenhouse Strawberry Production, George E. Meyer, Ellen T. Paparozzi, Elizabeth Walter-Shea, Erin E. Blankenship, Stacy A. Adams

Department of Agronomy and Horticulture: Faculty Publications

Photosynthethically active radiation (PAR) is a principle environmental variable used by horticultural specialists, agronomists and ecosystem modelers to characterize the quantity and quality of light conducive to plant growth and development. Spatial distribution of PAR in a greenhouse can be quite variable and diffuse throughout the day time photoperiod, especially at low sun angles in northern regions of the United States. Four colors of reflective plastic mulches (white, red, olive, and black) were evaluated for winter-time strawberry (Fragaria × ananassa Duch.) production based on their reflectance and transmittance properties in a double-polyethylene, plastic-glazed Quonset greenhouse inNebraska. The spectral properties …

Effectiveness Of Grass Filters In Reducing Phosphorus And Sediment Runoff, Ahmed Al-Wadaey, Charles S. Wortmann, Thomas G. Franti, Charles A. Shapiro, Dean E. Eisenhauer

Department of Agronomy and Horticulture: Faculty Publications

Surface water contamination can often be reduced by passing runoff water through perennial grass filters. Research was conducted in 2006 to 2008 to evaluate the size of cool season grass filters consisting primarily of tall fescue (Festuca arundinacea Schreb) with some orchard grass (Dactylis glomerata L.) relative to drainage area size in reducing runoff sediment and phosphorus (P). The soil was Pohocco silt loam Typic Eutrochrepts with a median slope of 5.5%. The grass filters occupying 1.1 and 4.3% of the plot area were compared with no filter with four replications. The filters were planted in the V-shaped …

Structural Variants In The Soybean Genome Localize To Clusters Of Biotic Stress-Response Genes, Leah K. Mchale, William J. Haun, Wayne W. Xu, Pudota B. Bhaskar, Justin E. Anderson, D. L. Hyten, Daniel J. Gerhardt, Jeffrey A. Jeddeloh, Robert M. Stupar

Department of Agronomy and Horticulture: Faculty Publications

Genome-wide structural and gene content variations are hypothesized to drive important phenotypic variation within a species. Structural and gene content variations were assessed among four soybean (Glycine max) genotypes using array hybridization and targeted resequencing. Many chromosomes exhibited relatively low rates of structural variation (SV) among genotypes. However, several regions exhibited both copy number and presence-absence variation, the most prominent found on chromosomes 3, 6, 7, 16, and 18. Interestingly, the regions most enriched for SV were specifically localized to gene-rich regions that harbor clustered multigene families. The most abundant classes of gene families associated with these regions …

Social Variability In The Emergence Of The Pueblo World, Richard Wilshusen, Gregson Schachner, James R. Allison

Faculty Publications

Between A.D. 650 and 950, there was a near total reorganization of society in the northern Southwest. In some areas, intensive agriculture, high population growth rates, and large villages appeared. In others, diverse mixes of subsistence strategies enabled the creation of aggregated communities and semi-sedentary settlements within the same landscape. A third pattern of high mobility and seasonal use of smaller settlements defined much of the periphery. In many areas, people pursuing more than one of these patterns resided simultaneously. We propose that the patterns established by A.D. 800 were integral in the shaping of later Pueblo history.

Low Frequency Temperature Variability And Native American Horticulture In The Northern Southwest And Eastern Great Basin, James R. Allison

Faculty Publications

Recent paleoclimatic studies reconstruct low-frequency variability in temperature that may have affected the success of Native American horticulture. Potential effects of this temperature variability include shifts in the range of elevations within which horticulture was viable, and changes in the northern limits of horticulture- based economies. This paper examines radiocarbon dates and other chronological data from Fremont and Puebloan sites in Utah, eastern Nevada, and northwestern Arizona, comparing the low-frequency temperature reconstructions with the timing of expansion and contraction in the northern frontier of maize horticulture and temporal shifts in the elevations of farming settlements.

Meanwhile, In The West: Early Pueblo Communities In Southeastern Utah, James R. Allison, Winston B. Hurst, Jonathan D. Till, Donald C. Irwin

Faculty Publications

The early Pueblo settlement of what is now southeastern Utah exhibits patterns that complement and contrast with trends in better-known regions such as southwestern Colorado (see Wilshusen et al., Chapter 2). Shortcomings in the current data limit the detail we can include in this description, but a number of patterns are clear. This chapter elucidates the patterned variability in the area's settlement strategies, the basic trends associated with social organization, and the basic demographic trends through time. We hope to develop, in the end, a basic historical narrative for these last centuries of the first millennium.

Kant And A Problem Of Motivation, David Jensen

Faculty Publications

In The Moral Problem, Michael Smith argues that there is an on-going tension in discussions among moral philosophers between the putative objectivity of morality, the practicality of moral judgments, and Hume’s view of motivation.¹ From an agent’s point of view, putatively objective claims imply cognitivism, the view that moral judgments express beliefs about the way the world is morally.² But if moral judgments are practical and on Hume’s view of motivation dependent on the desires of an agent, then from a moral standpoint, we risk making claims that the agent cannot be motivated to act upon.³ In …

Lubrication And Wear At Metal/Hdpe Contacts, Aydar Akchurin

Mechanical Engineering and Applied Mechanics

In the thesis lubrication and wear at metal/HDPE contacts was addressed. In particular this type of contact occurs in artificial joint replacements. Wear of HDPE was recognized as a major factor limiting device performance. In the thesis, fully implicit fully coupled numerical approach was developed to simulate lubrication and wear. Approach allows solving stationary and transient problems for rough surfaces in a wide range of parameters. Wear coefficients were estimated from experimental data. Wear particles formed in wear process were investigated. Particles were found to be approximately 100 nm in diameter and spherical in shape. Considering theoretical solutions, it was …

Brucellosis Epidemiology, Virulence Factors, Control And Molecular Targets To Prevent Bacterial Infectious Diseases, Robert Mugabi

Microbiological Sciences

Brucellosis is a bacterial zoonosis that infects both professional phagocytic and nonphagocytic cells in the hosts. Brucella intracellular survival is important for its virulence. In a study to establish the seroprevalence and risk factors of brucellosis in livestock in Kazo and Buremba sub-counties of Kiruhura district, Uganda, fifty goat and 112 bovine serum samples were tested for Brucella antibodies. The prevalence of Brucella antibodies in goats and cattle was 26.0% and 38.4% respectively, while individual seroprevalence rates by livestock breeds were 10.7% (cross-breed goats), 45.5% (local goat breeds), 49.1% (cross-breed cattle), 31.0% (local cattle breeds), and 17.4% (exotic cattle breeds) …

Emerging Infectious Diseases With Limited Treatment Options: The Case Of Ebola Hemorrhagic Fever In Uganda And Shiga Toxin Producing Escheria Coli In The United States, Rahel Dubiwak Gemmeda

Microbiological Sciences

Emerging infectious diseases are diseases that newly emerge in a population or change the frequency or spatial distribution of their occurrence. Ebola Hemorrhagic Fever (EHF) and Shiga Toxin-producing Escherichia coli (STEC) infections are among diseases that emerged in the 1970s. The two diseases have limited treatment options with no vaccines. This paper is based on two case studies. The first case study utilized data from the 2007/2008 EHF outbreak in Uganda and investigated the epidemiological and clinical aspects of the outbreak. The second case study was based on a study done on STEC isolates collected from beef cattle at the …

Drivers Of Infectious Disease Outbreaks: How Climate, Environment And Disease Control Programs Influence Occurence Of Infectious Disease Outbreaks, Michael Muleme

Microbiological Sciences

This research study described the factors driving infectious disease outbreaks using Foot-and-mouth disease (FMD) in Uganda and Lyme disease in North Dakota (ND), Minnesota (MN) and Wisconsin (WI) as case studies. Retrospective data on FMD vaccines and outbreaks in Uganda (2001 – 2010) and Lyme disease in ND, MN and WI (1990 – 2011) was used. The time (7.5 weeks) taken to respond to FMD outbreaks, limited serotyping/subtyping (9/121) of outbreaks and the low percentage of cattle vaccinated (2.1 – 21.2%) portray ineffective control programs. Similarly, increase in fall temperature (P = 0.0189) and annual precipitation (P = 0.0250) were …

Nathan Richardson And The Editions Of The New Method For The Pianoforte, Sarah Kaye Prigge

Music

Those studying music during the mid-nineteenth century in the United States began to experience music education through many of the models of pedagogy that are still in use at the present time. The use of a method book for music study was a new concept. A few more serious piano students traveled to Europe to study with the major performing artists of the day. As the number of homes with pianos increased, so did piano method books for home use. Women of the gilded age were encouraged to pursue music, most often for the purpose of playing at home and …

3 Nephi 9:19–20: The Offering Of A Broken Heart, Dana M. Pike

Faculty Publications

As recorded in the Book of Mormon (3 Nephi 8), the atoning death of Jesus Christ in Jerusalem brought prophesied destruction and darkness in the Americas. Following approximately three hours of terrible devastation (8:19), a “thick darkness” engulfed the land for three days (8:20, 23; 10:9). During this period of darkness the voice of Jesus was “heard among all the inhabitants of the earth, upon all the face of this land” (9:1).
