Kinetics, mass transfer, and mass re-equilibrium for arsenate adsorption on iron oxide-based carbons
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Removal of arsenic (As) from drinking water sources is much needed worldwide, and small water treatment systems, such as point-of-use (POU) treatment, could be an effective...
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 ...
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...
Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
Development and application of vegetative buffer width modeling using geographic information systems
(University of Missouri--Columbia, 2009)
of performance could potentially require wider or narrower buffer widths in order to meet certain stormwater management criteria. This method was successfully demonstrated within the LaBarque Creek watershed located southwest of St. Louis, Missouri for three...
Characterization of black walnut (Juglans nigra) cultivars for agroforestry systems
(University of Missouri--Columbia, 2022)
domesticated orchard crop, as opposed to just the high-quality timber for which it is well-known. However, field observations suggest significant variation in tree architecture and phenology amongst cultivars, which is likely to influence complementarity...
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)
through three means: proton nuclear magnetic resonance (1H NMR), ultraviolet-visible spectroscopy (UV-Vis) and cyclic voltammetry (CV). While a working universal heavy metal sensor was not achieved during this research project, it advanced the progress...
Copper (I) coordination networks synthesized with solid-solid reactions
(University of Missouri--Columbia, 2008)
of the solid-solid reaction mechanism. The crystalline reagents led to crystalline products with no amorphous phase. The nitrogen containing bridging ligands, 4,7-phenanthroline, 4,4'- dipyridyl, and trans-1,2-bis(4-pyridy1)ethylene in addition to 1,3-dithiane...
The effects of temperature and admixture handling on lipid emulsion stability in centrally administered veterinary parenteral nutrition (PN) admixtures
(University of Missouri--Columbia, 2008)
This research centered on veterinary parenteral nutrition (PN) admixtures which are mixtures of amino acids, dextrose, and lipid emulsions designed for the intravenous provision of nutrition to small animal patients. ...
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 ...
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...
Simulating cottonwood tree growth in flood plains using the LIGNUM modeling method
(University of Missouri--Columbia, 2006)
simulation model, was applied to simulation of the cottonwood growth in a flood plain area in central Missouri. The key characteristics of the LIGNUM model are the linkage between tree spatial structure and physiological function. L-system was adopted...
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...
Ecological genomics of divergence, admixture, and fitness in the smallmouth bass (Micropterus dolomieu)
(University of Missouri--Columbia, 2021)
their extensive native distribution. Much less is known about levels and distribution of diversity within the species. In 1940, Carl Hubbs and Reeve Bailey published descriptions of two distinct subspecies: the Northern Smallmouth Bass (M. d. dolomieu), inhabiting...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
Clinical deterioration and perception of cues among medical surgical nurses
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In the medical-surgical setting, failure to rescue events continue to remain prevalent. While failure to rescue events are often proceeded by changes in patient cues (i.e. vital...
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 ...
An attentional theory of issue-carrying capacity
(University of Missouri--Columbia, 2018)
A plethora of research in cognitive and behavioral psychology showed that there are significant differences in the way men and women process political and social information. It has been widely accepted that women show ...
