Determination of the efficacy of an applied vacuum at the skin surface during the laser therapy of Port Wine Stain (PWS) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
We will be doing experiments ex vivo using pig skin, which is very similar and much more attainable than human skin, to test the stress vs. strain relationship, elasticity (Young's Modulus) and research skin mechanics. ...
Impact of effective instruction within middle school classrooms on at-risk student problem behavior [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Teachers are increasingly faced with students who present challenging behavior in the classroom. When faced with such challenges, educators look for effective ways to manage problem behaviors, as well as to prevent problems, ...
Investigation of type I collagen deposition in the glomeruli of COL1A2 deficient mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Type I collagen is the most abundant structural protein in the body, playing a major role in the strength and integrity of connective tissues. Alterations in the synthesis and structure of type I collagen result in a number ...
Modern day Jezebels: Racialized sexuality and the images of black women in contemporary hip-hop videos
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Hip-hop music emerged in the 1970's as a countercultural strategy to deter inner city youth from the influence of violence and gangs; it was a form of social expression. The dominant images in early hip-hop music videos ...
Expression of aT4g27260/GH3-5/GH3a studied with in situ hybridization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tropisms, the responses of plants to external stimuli, have been studied as important evolutionary adaptations and as possible areas of future advantageous genetic manipulation. The goal of our current research is to ...
A study of wireless sensor networks with focus on node localization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Due to research in low-power, cheap wireless communications, Wireless Sensor Networks (WSN) has become one of the most exciting new fields of interest within computer science and engineering. Just as the Internet has made ...
Benefits of soy-based feeds for fetal estrogen levels and obesity in adulthood
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
We examined the effect of maternal exposure to naturally occurring estrogenic chemicals in diets on circulating levels of estradiol in mouse fetuses. An animal's specific response to estrogen can vary according to the time ...
Mitochondrial DNA insertion into nuclear chromosomes of maize
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Every mitochondrion contains its own DNA separate from the nucleus. Over evolutionary time, most of the mitochondrial genes have moved to the nucleus so that now mitochondria require nuclear DNA to function. This type of ...
Effect of Salmonella typhimurium on human cancer line tumors in mice [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Research of bacteria-driven degeneration of tumor cells, initially pioneered by Dr William Coley in 1893 using heat-killed mixtures of streptococci, has led to the scrutiny of the enterobacteria species Salmonella typhimurium ...
Neonatal exposure to xenobiotic estrogen may alter the adult immune response and exacerbate endometriosis in mice [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Endometriosis is a common medical condition affecting 5-10% of women worldwide and often results in severe cramps, pelvic pain, and infertility. The condition occurs when endometrial tissue, which escapes into the peritoneal ...
Role of the domain 4 rotation in PMM/PGM from P. aeruginosa during catalysis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The enzyme phosphomannomutase/phosphoglucomutase (PMM/PGM) belongs to the alpha-D-phosphohexomutase enzyme superfamily. It catalyzes the reversible conversion of 1-phospho to 6-phospho sugars. The reaction mechanisms ...
Characterization of transposon insertion mutants in desulfovibrio vulgaris hilderborough by sequencing genomic DNA [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Tn5 transposon mutagenesis occurs by a mechanism in which a segment of DNA (transposon) encoded in a plasmid is inserted into genomic DNA (the target) by a conservative (cut-and-paste) mechanism. When the insertion position ...
Testing the neural locus of affective priming effects [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Research has consistently shown that participants are faster to categorize the valence (positivity or negativity) of an affective target when it is preceded by a stimulus (prime) that shares its valence compared to one ...
What teachers should know: Comparison of 4th grade mathematics in Hong Kong and the U.S. [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The purpose of this study was to compare 4th grade mathematics teacher in Hong Kong and United States responses to teacher readiness, professional development and participation and overall teacher satisfaction. Data was ...
Differences between Martin Luther's preaching and theology on sexual morality [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
I am investigating how Martin Luther attempted to change sexual attitudes, specifically about pleasure in sex, through his sermons, in the age of the Reformation. Whereas the Church generally stigmatized sex, even within ...
Convection boiling in two-phase heat transfer [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
It is the mission of my research to investigate the heat transfer performance of a convective boiler working in two-phase on the microscale. The information obtained from this research will eventually be used in conjunction ...
Effect of assumptions by pre-service teachers concerning family life, extracurricular involvement and socioeconomic status [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The state of Missouri wants to produce highly qualified educators in order to facilitate high performing students; because of this it is vital that pre-service teachers alter their expectation in order to maintain high ...
Laser ablation of necrotic tissue to promote healing in burn injury [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Each year approximately 40,000 people are hospitalized due to burn injuries. The majority of our population is familiar with the superficial burns that result from overexposure to the sun, commonly known as sunburn. These ...
