Aquifers and soil filter effect : nitrogen in the environment (EQ, 2017)
(University of Missouri--Columbia. Extension Division, 2017)
Streambank erosion and risk assessment of contaminant transport in Missouri watersheds
(University of Missouri--Columbia, 2010)
Sedimentation and herbicide are significant water quality concerns in claypan watersheds. Two separate watershed-scale studies were conducted in the Central Claypan Region of northeastern Missouri. One project investigated the effects of season...
The politics of CO2 emissions
(University of Missouri--Columbia, 2020)
in responding to tackling climate change problems. Therefore, investment and strategic intervention for maintaining institutional quality and adopting institutional reform where needed merit more in-depth research initiatives....
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...
Operational analysis of cross-country trips on rail in Vietnam
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The analysis of current transit conditions is vital for planning and forecasting future transit demand. Previous analyses of Vietnam railways have been limited in both data...
Clothianidin decomposition in Missouri wetland soils
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Neonicotinoids are a class of pesticides that have been prevalently used in agriculture since the 1990s. Globally, most neonicotinoid application ([about]60%) is delivered via...
Estimating Water Quality, Air Quality, and Soil Carbon Benefits of the Conservation Reserve Program
(Food and Agricultural Policy Research Institute (FAPRI) at the University of Missouri-Columbia, 2007-01)
This report estimates how field and buffer practices affect the amount of soil and nutrients leaving the field.
Three essays on food security, agricultural productivity, and commodity basis
(University of Missouri--Columbia, 2021)
local, growing season, and regional precipitation, on Missouri corn and soybean basis. We document statistically significant linear and nonlinear basis responses in corn and soybean models for local and growing season precipitation variations. We also...
Development and applications of label-free optofluidic ring resonator biosensor
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation presents the development and applications of label-free optofluidic ring resonator (OFRR) sensor platform. The OFRR sensor naturally integrates the optical...
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 ...
Acrylate synthesis from carbon dioxide - ethylene coupling catalyzed by first-row transition metal complexes
(University of Missouri--Columbia, 2021)
Carbon dioxide (CO2) is an abundant and renewable carbon source than can be used as feedstock for the synthesis of value-added materials. One such material is acrylic acid, and acrylate derivatives, which can be used in ...
Hydrodynamic characteristics and capillary-assisted heat transfer enhancement of non-condensing/condensing two-phase flows
(University of Missouri--Columbia, 2020)
Interfacial characteristics of two-phase flows were studied through visualization experiments and numerical simulation using computational fluid dynamics (CFD) based on the volume-of-fluid (VOF)-continuum surface force ...
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...
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...
The economics of land disposal of municipal effluent
(University of Missouri--Columbia, 1972)
"Objectives of the study: The study attempts to analyze the possibilities of utilizing wastewater for agricultural production, particularly involving the use of irrigation. Various economic questions concerning the economics ...
Hierarchical spatio-temporal models for environmental processes
(University of Missouri--Columbia, 2007)
The processes governing environmental systems are often complex, involving different interacting scales of variability in space and time. The complexities and often high dimensionality of such spatio-temporal processes can be effectively addressed...
Investigation of CO2 capture systems, Lewis acid-base pairs, and oscillating reactions with electronic structure theory and kinetics-based approaches
(University of Missouri--Columbia, 2020)
the capture of CO2 by small alkylamines. The quality of that discussion was tested directly with the work described in Chapter 2. The work that led to Chapter 2 was an enormous learning experience; it was amazing to see all the pieces of the complicated multi...
Great Lakes lake trout early mortality syndrome (EMS) : contaminants, thiamin status, and their possible interaction
(University of Missouri--Columbia, 2006)
Salmonid populations in the Great Lakes experienced a decline in the early twentieth century, presumably due to over-fishing combined with the introduction of exotic parasites such as the sea lamprey. Despite intensive ...
Specific bio-modeling and analysis techniques at cellular and systems level
