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 …

Exponent: High Speed Cubesat Radio, Dana Sorensen

Undergraduate Honors Capstone Projects

Software Defined Radios (SDR) are limited by their usable bandwidth, which restricts how quickly they can transmit or receive data. The High Speed CubeSat Radio (HSCR) is capable of transmitting and receiving higher bandwidth signals by combining the bandwidths of several individual SDR transceivers. The HSCR performs phase correction to seamlessly stitch the bandwidths of each individual SDR into a single larger bandwidth.

By increasing the number of SDRs inside the HSCR, the bandwidth of the overall system will increase. This increase in bandwidth is limited only by the speed of the processing unit in working with received or transmitting …

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, …

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 …

Italian Domination On Ladders And Related Products, Bradley Gardner

Electronic Theses and Dissertations

An Italian dominating function on a graph $G = (V,E)$ is a function such that $f : V \to \{0,1,2\}$, and for each vertex $v \in V$ for which $f(v) = 0$, we have $\sum_{u\in N(v)}f(u) \geq 2$. The weight of an Italian dominating function is $f(V) = \sum_{v\in V(G)}f(v)$. The minimum weight of all such functions on a graph $G$ is called the Italian domination number of $G$. In this thesis, we will consider Italian domination in various types of products of a graph $G$ with the complete graph $K_2$. We will find the value of the Italian domination …

A Past Never Past: An Analysis Of Slavery And Reparation At The University Of Mississippi, Allen Coon

Honors Theses

The University of Mississippi was built using slaves, but the enslaved and their descendants were willfully denied admission to the university until forced desegregation in 1962. This interdisciplinary study employs a qualitative content analysis of antebellum university board of trustees and faculty minutes to investigate the benefits that slavery conferred to the university and the harms that slavery inflicted upon the campus enslaved. Analysis finds that slavery was a standard operation, that extrajudicial violence against slaves was a campus tradition, and that white supremacy was an institutional ideology at the University of Mississippi. This thesis integrates African American reparations literature …

Wind-Driven Setup, Roughness, And Drag Over A Depth- And Fetch-Limited Coastal Estuary, Jeffrey Allen Colvin

Theses and Dissertations

The understanding of the momentum exchange across the air-sea interface is critical to accurately model and forecast wind speed, wave properties, setup, and circulation. This is particularly true for a restricted estuary, such as the Indian River Lagoon (IRL), where wind is the driving force behind water movement due to the limited number of direct ocean connections. Current atmospheric and hydrodynamic models use formulations of the drag coefficient and/or roughness length based on open ocean studies in which wave properties are not considered. This dissertation develops two parameterizations – one for wind setup and one for the drag coefficient – …
