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 ...
Optical stimulation of quantal exocytosis on transparent microchips
(University of Missouri--Columbia, 2007)
) film was sputter-deposited onto glass coverslips, which were then patterned into 24 cell-sized working electrodes (2̃0 [mu]m by 20 [mu]m). We loaded bovine chromaffin cells with acetoxymethyl (AM) ester derivatives of the Ca²⁺ cage NP-EGTA and Ca...
A shellabration of early life : exploring the taphonomy, diversity, and distribution of small shelly fossils surrounding archaeocyathid reef systems in the Harkless System, Death Valley, NV
(University of Missouri--Columbia, 2023)
framework builders and their small shelly fossil (SSF) inhabitants. This study focuses on lower Cambrian (Series 2, Stage 4) SSF assemblages from the Harkless Formation in southern Esmeralda County, Nevada, as a comprehensive systematic and quantitative...
Comprehensive approach to dietary inclusion of high oleic soybean oil in monogastrics
(University of Missouri--Columbia, 2020)
The banning of partially hydrogenated oils in food processing by the FDA has led to a search for alternative oil sources with a decreased potential for oxidation. While marketed and founded for use in the food industry, ...
Optical reflectance in fibrous tissues and skeletal muscles
(University of Missouri--Columbia, 2008)
We studied diffuse optical reflectance in two anisotropic biological tissues: high moisture soy extrudates and skeletal muscles. High moisture extrusion of soy proteins can produce healthy alternative protein sources that ...
Quantum aspects of roaming dynamics
(University of Missouri--Columbia, 2020)
aspects of roaming reactions. Here, a few different molecules (C3H3Cl, HDCO, and H2CO) were investigated with the goal of characterizing roaming radicals on the ground state, where roaming observations have primarily occurred. Knowledge of the excited...
Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)
Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ...
Atrazine transport through a glacial till aquifer in north-central Missouri
(University of Missouri--Columbia, 2009)
in the aquifer is not well known. With the continued use of atrazine, the concentration in the aquifer could increase to levels of concern or decrease if the conditions are not favorable for persistence. Beginning in the Fall 2007 and continuing through the Fall...
Hydrogen production from biomass
(University of Missouri--Columbia, 2006)
from a renewable source such as biomass provides a domestically available, CO2 neutral, non-polluting form of energy. The goal of the work presented in this thesis was to develop two different methods to produce hydrogen gas using biomass as a renewable...
Structural supramolecular constructs of spheres and tubes
(University of Missouri--Columbia, 2006)
, a greener synthesis for biologically important molecules called hydantoins and a new crystal motif involving potassium nitrate and cucurbit[6]uril. The second project examined the solid state structure of C60 and C70 fullerene and how they interact...
Understanding Arabidopsis ion homeostasis in the post-genomic era : assigning function to two proteins involved in iron metabolism
(University of Missouri--Columbia, 2006)
Two projects studying different aspects of iron deficiency in the model plant Arabidopsis thaliana are detailed here. The first project describes the isolation and characterization of the Arabidopsis frd4-1 and frd4-2 mutants that do not induce Fe...
Experimental and theoretical studies of CO2 capture from air and of crystalline, ferroelectric, non-linear optical materials
(University of Missouri--Columbia, 2022)
approaches. In Chapter 1 to 3, we focused on a Rubisco inspired CO2 capture material, which is made of tetrapeptide KDDE. In chapter 1, we investigated the thermochemistry of the small amine system with full conformational space and determined the best method...
Importance of agritourism for agripreneur goal accomplishment
(University of Missouri--Columbia, 2010)
others (McGehee & Kim, 2004; Nickerson et al., 2001). This study examined the importance of agritourism in accomplishing 16 economic and intrinsic entrepreneurial goals of agritourism providers, as well as the farm household and business attributes...
Waste plastic storage stability impact toward asphalt binder and mix performances
(University of Missouri--Columbia, 2022)
diameter, and PE19 modified binder was stored in the tube for 48 hours at 1630C, akin to standard D7173 (storage stability standard). Upon completion of 24 hours of freezing, the binder was sampled from the top and bottom of the scaled-up separation tube...
System modeling and control design of a two-stage metering poppet-valve system
(University of Missouri--Columbia, 2006)
The goal of this work is to develop mathematical models, stability criteria, and control designs for a two-stage poppet valve system with a simple back-side pipeline condition that may be used in a valve stack to create ...
Factors affecting neonatal beef calf metabolism and vigor
(University of Missouri--Columbia, 2021)
less colostrum available but greater serum protein concentrations. The objectives of the second study were to determine the effect of calving season on perinatal nutrient availability and neonatal vigor. Fall-born calves tended to have lighter birth...
Freshman interest group participation and second year academic success of engineering students
(University of Missouri--Columbia, 2019)
Students in their second year of college experience changes in support that can negatively impact their success. This phenomenon is commonly referred to as the sophomore slump, which can manifest itself as a decline in ...
Two brief treatments based on dialectical behavior therapy for binge eating across diagnoses and thresholds : results from a preliminary randomized dismantling study
(University of Missouri--Columbia, 2009)
. Furthermore, little research exists regarding treatment efficacy for eating disorder presentations that fall outside of the current diagnoses of anorexia nervosa, bulimia nervosa, and binge eating disorder. The curret study bolsters this area by examining...
Dance-based therapy to decrease fall risk in older persons
