In vitro three dimensional biomechanical comparison of two internal fixation methods in equine adult radii
(University of Missouri--Columbia, 2007)
Radius fracture configurations conducive to internal fixation most often contain a spiral or oblique fracture of the distal diaphysis. The location and fracture configurations are biomechanically challenging because of the ...
Variation in the flood tolerance of three midwestern oak species
(University of Missouri--Columbia, 2007)
Several studies on flood tolerance of hardwood seedlings have suggested ecotypes exist among seed sources related to past flooding history and soil hydrological properties of the collection site. Our study examined differences ...
Molecular cloning and characterization of regulatory enzymes in threonine biosynthetic pathway from soybean
(University of Missouri--Columbia, 2007)
Soybeans (Glycine max [L.] Merr.) are a good source of protein and oil. Despite being a very good source of protein, soybeans nutritional value is limited by low proportion of sulfur amino acids methionine and cysteine ...
First-year composition and writing center usage
(University of Missouri--Columbia, 2007)
This study began with some initial questions about the interaction between the Composition Program and the Writing Lab at the University of Missouri-Columbia, with the first-year composition student's navigation of that ...
Decomposing individual and group differences of categorical variables with genetic factor model
(University of Missouri--Columbia, 2007)
The method of decomposing individual and group differences on ordered categorical variables into genetic and environmental factors is introduced. Although the genetic factor model is used to identify the relative contributions ...
Lithium and lithium isotopes in tourmaline as indicators of crystallization processes: a study of San Diego County pegmatites, California
(University of Missouri--Columbia, 2007)
The pegmatites of San Diego County, California, are part of the Mesozoic Peninsular Ranges Batholith of southwestern California and Baja California, Mexico. Three LCT- pegmatites were studied. The pegmatites have texturally, ...
Detection of Leptospira interrogans in fixed equine eyes affected with end-stage equine recurrent uveitis
(University of Missouri--Columbia, 2007)
Equine recurrent uveitis (ERU) is the most frequent cause of blindness in horses worldwide. Leptospira has been implicated as an etiologic agent in some cases of ERU. The objective of this study was to determine the presence ...
Neighborhood effects, convergence and growth in open economies of U.S. and Mexico
(University of Missouri--Columbia, 2007)
This dissertation consists of three papers. "Optional sales tax holidays: Which jurisdictions participate? Logit and a spatial analyses," I reviewed the literature regarding strategic interaction among jurisdictions and ...
Ethical considerations in the use of commercial agents in international student recruitment
(University of Missouri--Columbia, 2007)
Entrepreneurialism, globalism, and neoliberalism have influenced higher education to adopt a business model. Some critics view the university as having strayed from its public service role; others see this adaptation as ...
A pedagogy of freedom : using hip hop in the classroom to engage African-American students
(University of Missouri--Columbia, 2007)
The purpose of this study was to add to the knowledge base an understanding of the impact of culturally-relevant pedagogy, such as hip hop, on African American student engagement. The researcher viewed the study through ...
Assessing the capacity for collaborative ecosystem stewardship on private forestland in the Missouri Ozarks
(University of Missouri--Columbia, 2007)
Missouri's forestland totals nearly 15 million acres and a vast majority of this area, roughly 82 percent, is controlled by more than 300 thousand nonindustrial private forest (NIPF) owners. Consequently, meaningful long-term ...
Age effects on reproductive behavior in the treehopper umbonia crassiscornis (Hemipera: membracidae)
(University of Missouri--Columbia, 2007)
In many animal species females select mates based on male age. This choice is often linked to the reproductive benefits females derive. Age-based choice is also influenced by variation in the ability of males to find and ...
A study of NCAA division I athletes on the use and the effects of combining alcohol & energy drinks
(University of Missouri--Columbia, 2007)
The three main purposes of this study were (a) to determine the quantity-frequency rates of alcohol use, combined use (using an energy drink within plus or minus four hours of consuming alcohol), and energy drink use in a ...
Phosphorus nutrition in tall fescue : from stockpiling to seed production
(University of Missouri--Columbia, 2007)
Tall fescue (Festuca arundinacea) is the most important forage for beef production in the Midwest. Stockpiling tall fescue allows producers to extend the grazing season and reduce winter-feeding costs. In Missouri, forages ...
The role of teamwork in public child welfare caseworkers' intentions to leave
(University of Missouri--Columbia, 2007)
The high turnover rates among caseworkers have emerged in the past decade as one of the most serious issues within the public child welfare agencies. High turnover rates lead to reductions in case work quality with resulting ...
Adjustable speed drive bearing fault detection via support vector machine incorporating feature selection using genetic algorithm
(University of Missouri--Columbia, 2007)
This dissertation presents a novel method to detect bearing defects in Adjustable Speed Drives (ASD's), which are increasingly used in many commercial and industrial applications. The harmonics in pulse-width-modulation ...
Materials study supporting thermochemical hydrogen cycle sulfuric acid decomposer design
(University of Missouri--Columbia, 2007)
A laboratory scale sulfuric acid decomposer simulator was constructed at the Nuclear Science and Engineering Institute at the University of Missouri- Columbia. The simulator was capable of producing the temperatures and ...
Load transfer in reticulated and non-reticulated micropiles from large-scale tests
(University of Missouri--Columbia, 2007)
Using micropiles for slope stabilization is a proven technique but there are many uncertainties with how load is transferred from the soil to the structural elements. A large-scale model was constructed to test model slopes ...
The effects of regular tanning bed use and increased vitamin D status on bone mineral density and serum inflammatory markers in healthy women
(University of Missouri--Columbia, 2007)
Vitamin D is synthesized in the skin in response to UVB radiation and has an essential function in optimal bone health. Recent evidence has also implicated a role for vitamin D in a properly functioning immune system. The ...
