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...
Using feedback linearization to alter the performance of multiple linear hydraulic-actuators powered by the same pump
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this study, a feedback linearization technique is presented to improve the tracking and energy performances of a hydraulic system using multiple linear hydraulic...
Computational studies of gases adsorbed on graphene-like materials
(University of Missouri--Columbia, 2022)
Nanoporous activated carbons generate interest for their gas storage and separation potential. Generally, adsorbents are assumed rigid, even though they are formed by feeble quasi-2D flakes of graphene. In 2019, Schaeperkoetter ...
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 ...
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...
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 ...
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 ...
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 ...
From the lab bench to the fuel tank : development and analysis of novel adsorbents for hydrogen and natural gas storage
(University of Missouri--Columbia, 2020)
Hydrogen and natural gas offer a promising avenue towards reducing greenhouse gas emissions in the transportation sector; however, storage poses a non-trivial challenge, with current systems requiring prohibitively large ...
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. ...
Synthesis, characterization, and reactivity of actinide complexes bearing An-E bonds (An = Th, U; E = P, As)
(University of Missouri--Columbia, 2021)
Organoactinide complexes bearing An-E (An = Th, U; E = P, As) bonds were synthesized and reactivity studies were performed with various unsaturated and industrially/environmentally relevant small molecules in an effort to elucidate further...
Determination of saturated film densities and volumes for adsorbed hydrogen, and application to the calculation of the enthalpy of adsorption at room temperature
(University of Missouri--Columbia, 2018)
with 2.86 kg of University of Missouri monolithic carbon, under operation at 23 [degree]C (room temperature), 0 [degree]C (ice bath), and -79 [degree]C (dry-ice bath) and pressures 0-100 bar. Storage and fast charge/discharge data, including temperature...
A Python-based GIS simulation of a water balance for wetland decision-making
(University of Missouri--Columbia, 2021)
wetland site to determine the potential existence of the excess water component. The study area is a location within Pershing State Park within Linn County, Missouri. Three goals have been set in this research in order to achieve the ultimate goal...
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...
Three essays on biofuel policies and aggregate supply curve
(University of Missouri--Columbia, 2022)
The first essay investigates the impacts of Brazil's new biofuel policy, namely RenovaBio. RenovaBio aims to reduce greenhouse gas (GHG) emissions in the transportation sector through expansion of biofuels by requiring ...
Three essays on applied economics and finance
