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...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
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 ...
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...
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 ...
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 ...
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...
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)
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 ...
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...
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 ...
Long Term Ocular Drug Delivery with Novel Pentablock Copolymers; Part I: Composite Nanoformulation of Macromolecules For Back of the Eye Diseases, Part II: Dexamethasone Nanoparticle to Develop an In Vitro Model for Glaucoma
(University of Missouri -- Kansas City, 2017)
Pentablock (PB) copolymers have been successfully synthesized for long term delivery in
the treatment of posterior segment ocular diseases. PB copolymers are comprised of FDA
approved biodegradable polymer such as ...
A study of bacterial cellulose confined ionic liquid and deep eutectic solvent gel materials
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Pollutants have become more prevalent in the air, water, and ground, necessitating the development of technologies that would help, limit, reverse, monitor, measure...
Merging technology development of trapped ion mobility spectrometry quadrupole time-of-flight mass spectrometry with biological investigation of Medicago truncatularoot exudates
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] "New commercial ion mobility instrumentation has the potential to improve current analytical techniques, but developments need to be applicable to real-world problems...
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 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 ...
Six months of resistance training or plyometrics exercise positively affects bone mineral density and bone turnover marker ratios in men with osteopenia
