Organ-Distribution Of The Metabolite 2-Aminothiazoline-4-Carboxylic Acid In A Rat Model Following Cyanide Exposure, Ilona Petrikovics, David E. Thompson, Gary A. Rockwood, Brian A. Logue

Chemistry and Biochemistry Faculty Publications

The reaction of cyanide (CN⁻) with cystine to produce 2-aminothiazoline-4-carboxylic acid (ATCA) is one of the independent detoxification pathways of cyanide in biological systems. In this report, in vivo production of ATCA and its distributions in plasma and organs were studied after a subcutaneous sublethal dose of 4 mg/kg body weight potassium cyanide (KCN) administration to rats. At this sublethal dose of KCN, ATCA concentration was not significantly increased in the plasma samples, however, it was found significantly increased in liver samples. These results suggested that ATCA might not be a good diagnostic biomarker in plasma for sublethal …

Soil Organic Carbon Maintenance Requirements And Mineralizatyion Rate Constants: Site Specific Calculations, David Clay, Gregg Carlson, Sharon Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Over the past 100 years numerous studies have been conducted with the goal of quantifying the impact of management on carbon turnover. It is difficult to conduct a mechanistic evaluation of these studies because each study was conducted under unique soil, climatic, and management conditions. Techniques for directly comparing data from unique studies are needed. This paper: 1) demonstrates an approach for calculating SOC maintenance requirements and mineralization rate constants at different landscape positions; and 2) discusses techniques for conducting site- specific experiments and determining site-specific C sequestration potentials.

Seed Abundance For Waterfowl In Wetlands Managed By The Illinois Department Of Natural Resources, Joshua D. Stafford, Aaron P. Yetter, Christopher S. Hine, Randolph S. Smith, Michelle M. Horath

Natural Resource Management Faculty Publications

Managed wetlands on public lands in Illinois, United States, provide foraging habitats for migrating and wintering waterfowl. However, few studies have estimated abundances of waterfowl foods in mid-migration regions of North America, yet such information is needed to inform management and conservation decision-making. During 2005– 2007, we used a multistage sampling design to estimate moist-soil plant seed production (kg/ha, dry mass) and energetic carrying capacity at sites managed by the Illinois Department of Natural Resources and modeled variation in seed biomass. Average seed biomass among all sites ranged from 1,030.0 6 64.1 (SE) kg/ha in 2005 to 501.5 6 124.1 …

Real Number Rado Numbers For The Equation ∑_(I=1)^(M-1)▒X_(I+C=X_M ), Melanie Zinter

The Journal of Undergraduate Research

This paper will examine the type of Ramsey theory concerned with the preservation of solution to specific linear equations under set partition. That is, if a solution to a linear equation exists in the natural numbers, must one also exist within one set of a partition of the natural numbers? To differentiate sets of a partition of the natural numbers from one another, it is convenient to use colors. Then a solution in just one set of a partition of the natural numbers can be referred to as monochromatic solution, or a solution in a single color. [Page 1]

Upscaling Carbon Fluxes Over The Great Plains Grasslands: Sinks And Sources, Li Zhang, Bruce K. Wylie, Lei Ji, Tagir G. Gilmanov, Larry L. Tieszen, Daniel M. Howard

Natural Resource Management Faculty Publications

Previous studies suggested that the grasslands may be carbon sinks or near equilibrium, and they often shift between carbon sources in drought years and carbon sinks in other years. It is important to understand the responses of net ecosystem production (NEP) to various climatic conditions across the U.S. Great Plains grasslands. Based on 15 grassland flux towers, we developed a piecewise regression model and mapped the grassland NEP at 250 m spatial resolution over the Great Plains from 2000 to 2008. The results showed that the Great Plains was a net sink with an averaged annual NEP of 24 ± …

Engineering Our Climate: A Critical Review Of The Geoengineering Response To Climate Change, Gary Huff

The Journal of Undergraduate Research

Various responses to greenhouse gas induced climate change have been proposed within the literature. While the most desirable response is to dramatically reduce greenhouse gas emissions, technological and financial obstacles make it difficult to realize the reductions necessary to solve the climate change problem. Several geoengineering schemes have been proposed that would compensate for increased greenhouse gas concentrations by reducing the solar energy absorbed by Earth. The most notable of these shortwave climate engineering schemes involves injection of sulfur aerosols into the stratosphere in order to disperse incoming radiation. This paper examines the geoengineering responses to climate change and demonstrates …

Xenakis' Combination Of Music And Mathematics, Janelle Anderson

The Journal of Undergraduate Research

My interest in using mathematics in music composition stems from the works of the contemporary composer Iannis Xenakis. As a physics and music education major I am able to combine both fields of study for this topic. Although Xenakis wrote many orchestral compositions it is his vocal music that I have concentrated on as I too am a singer. Graphic representation and new music notation are among the methods used to analyze his music. I found that his first choral work was called “Nuits,” which I proceeded to analyze. I also found myself interested in the analysis of a more …

Productivity And Trophic Interactions In The Missouri River Impoundments, Mark J. Fincel

Electronic Theses and Dissertations

Standardized monitoring is a vital component of fisheries assessment in Missouri River impoundments. In South Dakota, annual variation in fish growth and abundance is used to monitor changes in fish populations and develop strategies (i.e. regulations) for managing recreational fishes. Although variation in fish abundance provides important insight into the status of fish populations, it can be difficult to link these changes to environmental conditions (i.e. hydrology) without concurrent information about reservoir productivity. Measures of nutrient concentration, algal biomass, and zooplankton composition/abundance provide important insights into reservoir productivity, but standardized approaches for collecting these measures have not been developed for …

Movement Patterns, Survival, And Sightability Of White-Tailed Deer (Odocoileus Virginianus) In Eastern South Dakota, Kevin A. Robling

Electronic Theses and Dissertations

Limited information is available on white-tailed deer (Odocoileus virginianus) movements, survival, density, and resource selection in the Prairie Pothole Region of South Dakota where semi-permanent wetland densities are relatively high. Primary objectives of this study were to develop a sightability model for aerial surveying and document seasonal movement patterns and survival rates for white-tailed deer in this region. Secondary objectives were to calculate seasonal home ranges, daily and seasonal movements relative to management unit boundaries, determine cause specific mortality, and evaluate summer and winter resource use and selection. From February 2009 – February 2010, 43 adult female white-tailed deer along …

Population Viability Analysis Of Swift Fox (Vulpes Velox) At The Badlands National Park, Indrani Sasmal

Electronic Theses and Dissertations

The swift fox (Vulpes velox) was historically distributed in southwestern South Dakota including the region surrounding Badlands National Park (BNP). The species declined during the mid-1900s due to habitat fragmentation, non-target poisoning, and harvest. A remnant population occurred on USDA Forest Service lands in Fall River County, South Dakota. Following the successful reintroduction of the species in Canada (1983), a reintroduction program was initiated in BNP in the year 2003. Free-ranging swift fox from Colorado and Wyoming were translocated to BNP from 2003 to 2006. Despite these releases and observations of free-ranging swift fox occurring throughout western South Dakota, it …
