Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
been proposed as indicator taxa as they are reliant on insect food reserves and have recently experienced population declines. Thus, we developed two studies in floodplain wetlands to quantify neonicotinoids in Missouri wetlands and potential effects...
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...
Genetic and environmental factors influencing the weaning weight of beef calves
(University of Missouri, College of Agriculture, Agricultural Experiment Station, 1963)
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
material was packed to a bulk density of 1.3 Mg m[superscript -3] (81 lb ft[superscript -3]) in soil test beds subjected to a 61-mm h[superscript -1] (2.4-in hr[superscript -1]) simulated rainfall with a kinetic energy (KE) of 1.5 kJ m[superscript-2] h...
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...
Regional site response and uppermost mantle seismic structure of central and eastern united states
(University of Missouri--Columbia, 2019)
This dissertation examines seismological data from regional earthquake sources in order to examine the seismological character of the crust and uppermost mantle in central and eastern United States. Firstly, site amplification ...
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...
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 ...
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...
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...
Characteristics of mean flow and turbulence in bubble plumes
(University of Missouri--Columbia, 2023)
shear entrainment process within 40 cm height-of-rise. Hence, the integral model and the universal scaling using the plume length scale D(= gQg/4[pi][alpha]^2Ws^3 with g being gravitation acceleration, Qg being gas flow rate, [alpha] = 0.083 being a...
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 ...
Multivariate analyses of polygenic risk for impulsivity and alcohol use: a study of longitudinal trajectories of binge drinking in emerging adulthood
(University of Missouri--Columbia, 2022)
This dissertation aimed to extend previous genetic and neurobiological studies of the shared etiology of impulsive personality traits (IPTs), alcohol consumption and alcohol use disorder (AUD). The overarching goals were ...
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...
Proteomics and condensed tannin : an optimized method to characterize grape protein and the relationship to wine condensed tannin content
(University of Missouri--Columbia, 2021)
and condensed tannin. Also, condensed tannin content and proteome from Vitis interspecific hybrid cv. Chambourcin wine from 2018 and 2019 was studied more extensively with traditional and novel winemaking methods (exogenous condensed tannin additions early...
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...

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 ...
