Land application equipment for livestock and poultry manure management (2001)
(University of Missouri--Columbia. Extension Division, 2001)
Land application is the most desirable method for making use of the nutrients and organic matter in animal manure. The value of the manure is usually maximized if it can be substituted for the purchase of commercial fertilizer.
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 health and environmental...
Adoption of nutrient management practices
(University of Missouri--Columbia, 2008)
Off-farm income has recently been incorporated into the analysis of technology adoption, due to its increasing share in total farm household income in the U.S. Previous studies, however, found inconsistent results with ...
Studies of ruminant digestion, ecology, and evolution
(University of Missouri--Columbia, 2008)
This thesis examines ruminant digestion, ecology, and evolution, particularly where they can improve livestock production systems. We performed an experiment that estimated ruminal in situ degradation parameter values of ...
Hydrogen production from biomass
(University of Missouri--Columbia, 2006)
Biomass energy encompasses a broad category of energy derived from plants and animals as well as the residual materials from each. Hydrogen gas is an effective energy carrier which burns cleanly producing water as the only ...
Specific bio-modeling and analysis techniques at cellular and systems level
(University of Missouri--Columbia, 2006)
Modeling approaches are developed for two different levels, cellular (Part I) and systems (Part II), and used to develop insights into system performance. PART I consists of three chapters focusing on computational ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
Copper (I) coordination networks synthesized with solid-solid reactions
(University of Missouri--Columbia, 2008)
The use of solid-solid reactions in the development of one-, two-, and three dimensional Cu(I) coordination networks are discussed. The solid-solid reactions were monitored by a variety of instrumental techniques to achieve ...
Mating systems in Nicotiana longiflora and N. Plumbaginifolia : the effect of interspecific interactions
(University of Missouri--Columbia, 2008)
The research presented here was focused on the effects of interactions between Nicotiana longiflora and N. plumbaginifolia on their mating systems. First, I conducted a series of observations and pollination experiments ...
Multi-hazard resilience assessment of river-crossing bridges
(2021)
Bridge structures are required to possess high reliability and robustness against the concurrent effect of extreme loads and environmental attacks. To achieve such interrelated goals, it is necessary to assess the system performance and resilience...
Exploring the impact of peracetic acid on bacterial regrowth and plasmid release and developing a novel whole-cell biosensor to monitor the expression of quorum sensing genes
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Peracetic acid (PAA or CH3COOOH) is a promising alternative to chlorine-based disinfectants for water and wastewater treatment due to its strong antimicrobial properties and low...
Effects of prescribed fire on forest soil properties in the Ozark Highlands
(University of Missouri--Columbia, 2020)
/Forest Hills Land Type Association in the Black River Basin of southern Missouri. Weathered from Roubidoux sandstone and Gasconade dolomite, soils at the study sites contain large quantities of coarse fragments and reduced nutrient content. In 2015, fire...
Developmental programming by xenoestrogens
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Xenoestrogens (XE) are chemicals in the environment that mimic the body's natural steroidal estrogens. Developmental exposure to XE may interfere with normal hormonal signaling...
Evaluation and development of first order fire effects mortality model predictions for eastern hardwood forests
(University of Missouri--Columbia, 2018)
The First Order Fire Effects Model (FOFEM) is a useful tool for predicting fire-induced mortality in western coniferous forests. However, it lacks robust models for eastern hardwood species. Managers in the eastern United ...
High valent uranium dioxo and imido complexes : synthesis and structure
(University of Missouri--Columbia, 2008)
. Whereas high oxidation state ions dominate environmental speciation, the corresponding high-valent organometallics are rare. These hexa- and pentavalent ions are often stabilized by the isoelectronic oxo or imido ligands, which result in robust molecular...
Three essays on applied economics and finance
(University of Missouri--Columbia, 2023)
This dissertation empirically analyzes the financial decision-making of private and public corporations. It comprises four main chapters. The second and third chapters examine how private agents respond to fiscal policies ...
The culture wars & political polarization in perspective : why polarization and its perturbations are a persistant [i.e., persistent] puzzle in political science
(University of Missouri--Columbia, 2009)
Political polarization in the American electorate has received a great deal of attention in recent years with most of the research focusing on social issues and their impact on electoral outcomes. However, scant attention ...
An empirical approach to exploring the role of selective incentives in mitigating the free rider problem
(University of Missouri--Columbia, 2007)
The concept of free riding has been recognized as a challenge facing collective action organizations for centuries. However, the term free riding has been used to describe a range of alternative problematic actions and ...
Measuring and comparing the spatiotemporal evolution of accident hot spots
(University of Missouri--Columbia, 2022)
One reality of transportation systems is that vehicular accidents can happen practically anywhere and at any time. An increasing body of research suggests though that spatial and/or temporal dependencies (i.e., clusters ...
The synthesis and characterization of 1,1'-disubstituted ferrocene imine Schiff base ligand systems for use as potential environmental heavy metal cationic sensors
(University of Missouri--Columbia, 2008)
