Agroforestry buffer, biomass crop, and grain crop effects on soil quality and soil water use
(University of Missouri--Columbia, 2020)
may avoid soil degradation as well as improve soil and water quality. The objectives of this study were (i) to evaluate the effects of different perennial vegetative management systems and soil depth (10- cm depth increments from the surface to the 40...
Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
and landscape position, intact soil core samples (76 by 76 mm) were taken from the 0- to 10-, 10- to 20-, and 20- to 30-cm soil depths. For objective 2, soil profile samples were taken at 18 to 19 locations from each of two close-by fields and PAW capacity...
Effects of prescribed fire on forest soil properties in the Ozark Highlands
(University of Missouri--Columbia, 2020)
soil bulk density was measured at the 0-10, 10-20, and 20-30 cm depths before fire, and bulk density at the 0-10 cm depth was re-sampled two years post-burn. There was no change in bulk density of the whole soil and the fine soil fraction. Mineral soil...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
/Environmental eXtender (APEX) model was calibrated and validated for a 32-ha field from 1993 to 2002 for runoff, sediment, and atrazine loads. Two indices were developed using soil property and topography data, the Conductivity Claypan Index (CCI) and the Claypan...
Simulation and experimental study of the multichanneling rimfire gas switch
(University of Missouri--Columbia, 2005)
Since 1985, the Rimfire switch has been used extensively in accelerators at Sandia National Laboratories. Demands for increased future accelerator performance require improvements to the Rimfire switch. This thesis is both a theoretical...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
. This dissertation includes results from four studies conducted at the MU Greenley Research Center, Grace Greeley farm, and Ross Jones farm. Long-term, no-till research evaluated the influence of a wheat (Triticum aestivum L.), radish (Raphanus raphanistrum subsp...
The role of genetic background on the phenotypic severity of the osteogensis imperfecta murine (oim) COLIA2 gene mutation throughout postnatal development
(University of Missouri--Columbia, 2006)
Osteogenesis imperfecta (OI) is a diverse disease of type I collagen, the main structural protein in the body. It has been well documented that related individuals harboring the same OI-causing mutation can have very ...
A mixed method approach to exploring landowner interest in woody plantings to integrate conservation and production on Missouri farms
(University of Missouri--Columbia, 2022)
Agroforestry plantings can provide multiple benefits such as reduced soil erosion, decreased nutrient runoff, increased biodiversity, and greater farm income stability. This array of benefits makes them a promising ...
Essays on applied macroeconomics and monetary policy
(University of Missouri--Columbia, 2019)
The dissertation presents three essays in applied macroeconomics and monetary theory. First essay explores the existence of global financial cycles and examines the relationship between financial and macroeconomic sectors ...
Use of non-lethal endpoints to establish water quality requirements and optima of the Topeka Shiner (notropis topeka)
(University of Missouri--Columbia, 2017)
Water quality influences growth, development, and physiology of aquatic vertebrates. Current criteria on water quality assessments are primarily based on lethal level experiments (e.g. LC50 tests), which are poorly suited ...
Motivation for smoking and smoking cessation : a self-determination theory investigation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nicotine dependence is conceptualized as a disorder of motivation. Initial drug use is goal-directed, but with the development of dependence it becomes ...
Machine learning for mixed quantum-classical dynamics and transition metal chlorides oxidation potential via density functional theory
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] Chemical phenomena in our daily life are understood to be the result of physical interactions between matter. These interactions are governed by physical laws that mostly has been understood and ...
Behavioral responses of drosophila suzukii (diptera: drosophilidae) to olfactory and visual cues
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Selected fruit and leaf volatiles were assessed to determine their attractiveness to Drosophila suzukii Matsumura (Diptera: Drosophilidae). Two- and ...
Effects of hip joint orientation and skeletal torsion on human locomotor biomechanics and evolution
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] Bipedal locomotion is a defining feature of the human lineage. However, the form of bipedality in different hominin taxa and the timing of emergence of a human-like striding bipedal gait have ...
Impact of woody biomass production and biopower generation on US forests
(University of Missouri--Columbia, 2022)
This dissertation presents a study of environmental impact of woody biomass production and consumption on the eastern US forests. The first part is concerned with the impact of the exponential growth in trading of US ...
Three essays on the economics of pesticide use
(University of Missouri--Columbia, 2022)
Pesticides primarily benefit humans in terms of protection of food production, prevention of diseases, and weed control, but also potentially harm people and the environment. Given increasing current interest in human ...
Hiding in plain sight : camouflage in the corporate governance of IPOs
(University of Missouri--Columbia, 2012)
I show that quality of corporate governance incrementally explains IPO pricing and performance. I facilitate this by creating a measure of corporate governance, provided by the bylaws and charter of an IPO, called camouflage. ...
Lifestyle treatment in the regression of NASH: insulin resistance, lipid synthesis, and methodological innovation
