Comparing Wearer Dna Sample Collection Methods For The Recovery Of Single Source Profiles, Corissa J. Harris, Amanda J. Cardenas, Steven B. Lee, Brooke Barloewen

Themis: Research Journal of Justice Studies and Forensic Science

Wearer DNA is the deposit of epithelial cells on clothing worn by an individual. Detection of the last individual to handle or wear an item is often an important and desirable determination in forensic science. The most commonly used collection methods for wearer DNA include swabbing and scraping. These often result in mixture profiles. Recently, adhesives have been introduced as a possible reliable method for the collection of biological evidence. The goal of the research was to compare the current collection methods of swabbing and scraping with a gel film called Gel-Pak ‘0’ which shares similar properties with adhesives. Gel-Pak …

Nascent Nanocomputers: Dna Self-Assembly In O(1) Stages, Michael C. Barnes

Theses and Dissertations - UTB/UTPA

DNA self-assembly offers a potential for nanoscale microcircuits and computers. To make that potential possible requires the development of reliable and efficient tile assembly models. Efficiency is often achieved by minimizing tile complexity, as well as by evaluating the cost and reliability of the specific elements of each tile assembly model. We consider a 2D tile assembly model at temperature 1. The standard 2D tile assembly model at temperature 1 has a tile complexity of O(n) for the construction of exact, complete n x n squares. However, previous research found a staged tile assembly model achieved a tile complexity of …

Detection Of Bacterial Retroelements Using Genomics, Sen Mu

Electronic Theses and Dissertations

The reverse flow of genetic information can occur when a special DNA polymerase called Reverse Transcriptase (RT) copies the genetic information in an RNA molecule back into a complementary DNA. One type of RT encoding gene found in bacteria is called a retron element. Recent bacterial genome sequencing projects have revealed many examples of retron RT genes. This gene assignment is based on comparison with a few known retron RT proteins. However, RT proteins are highly diverse in their amino acid sequences, and thus the assigned identity of these RT proteins as retrons in genome databases is questionable. One way …

Peg Solitaire On Trees With Diameter Four, Clayton A. Walvoort

Electronic Theses and Dissertations

In a paper by Beeler and Hoilman, the traditional game of peg solitaire is generalized to graphs in the combinatorial sense. One of the important open problems in this paper was to classify solvable trees. In this thesis, we will give necessary and sufficient conditions for the solvability for all trees with diameter four. We also give the maximum number of pegs that can be left on such a graph under the restriction that we jump whenever possible.

Genetic Imbalances In Endometriosis Detected By Oligonucleotide-Array Based Comparative Genomic Hybridization, Natalie Burke

Electronic Theses and Dissertations

Endometriosis is one of the most common gynecological diseases as it is thought to affect up to 15% of the female population. Characterized by the growth and proliferation of endometrial tissue outside of the uterine cavity, it is a complex condition with varying degrees of severity and can affect multiple regions of the body with symptoms ranging from a total lack of symptoms to debilitating pain and infertility. The most accepted theory of how endometriosis initiates is that of retrograde menstruation; however, approximately 90% of women with unobstructed fallopian tubes are thought to have some menstrual debris in the peritoneal …

Variations In Phenotypic Plasticity And Fluctuating Asymmetry Of Leaf Morphology Of Three Quercus (Oak) Species In Response To Environmental Factors, Joseph Kusi

Electronic Theses and Dissertations

Leaf morphology of Quercus (oak) species is highly variable and complicated confounded with phenotypic plasticity and fluctuating asymmetry (FA). However, the study of variation is mostly limited to leaf morphology. This study was extended to plasticity and FA variations in Q. alba (white oak), Q. palustris (pin oak), and Q. velutina (black oak). It was hypothesized that light exposure, individual trees, leaf position, and other leaf traits will influence variation in these species. Leaves were sampled from trees of these species and their morphological traits were measured. Absolute asymmetry of leaf width and area were determined and plasticity of each …

On The Origin Of Shame: Feelings Of Disgust Toward The Self, John A. Terrizzi Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Shame and disgust are believed to be evolved psychological solutions to different adaptive challenges and, thus, independent emotions. Shame is thought to promote the maintenance of social hierarchies (Gilbert, 1997; Fessler, 2004), whereas disgust is believed to encourage disease avoidance (Curtis et al., 2004; Oaten et al., 2009). Although shame and disgust are often treated as orthogonal emotions, they share some important commonalities. Both shame and disgust involve bodily concerns, have been described as moral emotions, and encourage avoidance of social interaction. The purpose of the current studies was to investigate the relation between shame and disgust. More specifically, the …

Spring Studies And A Decision-Making Process To Guide Groundwater Contamination Prevention In An Agricultural Karst Basin, Erin D. Murphy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Groundwater contamination is a potential major health and environmental issue in karst aquifers because of rapid surface water to groundwater connections and conduit-dominated flow that may allow contaminants to move great distances from their source in a very short amount of time. Agricultural contaminants are a significant problem in Buckeye Creek basin in Greenbrier County, West Virginia. Pasquarell and Boyer (1995) found that cattle grazing near sinking streams, sinkholes, and springs contribute to the elevated levels of fecal coliform bacteria in the groundwater. Six sites in Buckeye Creek basin were monitored for fecal coliform contamination and then analyzed in order …

Remarital Chances, Choices, And Economic Consequences: Issues Of Social And Personal Welfare, Kevin Shafer, Todd M. Jensen

The Journal of Sociology & Social Welfare

Many divorced women experience a significant decline in financial, social, physical, and psychological well-being following a divorce. Using data from the NLSY79 (n= 2,520) we compare welfare recipients, mothers, and impoverished women to less marginalized divorcees on remarriage chances. Furthermore, we look at the kinds of men these women marry by focusing on the employment and education of new spouses. Finally, we address how remarriage and spousal quality (as defined by education and employment) impact economic well-being after divorce. Our results show that remarriage has positive economic effects, but that is dependent upon spousal quality. However, such matches are rare …

Environmental Economics: A Case Study For The Big Cottonwood Canyon Watershed, Robert Hull

Pomona Senior Theses

Environmental economics is the application of economic principles to the study of how natural resources are developed and managed. The methodologies used attempt to value ecosystem services provided by healthy, functioning natural lands and ecosystems. Ecosystem services attributed to natural lands contribute significant human welfare benefits that go largely undervalued or misrepresented in the decision-making process for the development of land. As environmental valuation methodologies and techniques continue to advance, policy decisions will be better able to create outcomes that maximize benefits for targeted populations and landscapes. The purpose of this paper is to first describe the methodologies used in …

Floatovoltaics: Quantifying The Benefits Of A Hydro-Solar Power Fusion, Abe Mckay

Pomona Senior Theses

A Mathematical Model For Antibiotic Resistance In A Hospital Setting With A Varying Population, Edward H. Snyder

Electronic Theses and Dissertations

Antibiotic-resistant bacteria(ARB) is causing increased health risk and cost to society. Mathematical models have been developed to study the transmission of resistant bacteria and the efficacy of preventive measures to slow its spread within a hospital setting. The majority of these models have assumed a constant total hospital population with the admission and discharge rates being equal throughout the duration. But a typical hospital population varies from day to day and season to season. In this thesis, we apply variable admission and discharge daily rates to existing deterministic and stochastic models which examine the transmission of single and dual resistant …

Citrus Tristeza Virus-Host Interactions, W. O. Dawson, S. M. Garnsey, Satyanarayana Tatineni, S. Y. Folimonova, S. J. Harper, S. Gowda

Department of Plant Pathology: Faculty Publications

Citrus tristeza virus (CTV) is a phloem-limited virus whose natural host range is restricted to citrus and related species. Although the virus has killed millions of trees, almost destroying whole industries, and continually limits production in many citrus growing areas, most isolates are mild or symptomless in most of their host range. There is little understanding of how the virus causes severe disease in some citrus and none in others. Movement and distribution of CTV differs considerably from that of well-studied viruses of herbaceous plants where movement occurs largely through adjacent cells. In contrast, CTV systemically infects plants mainly by …
