Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
(University of Missouri--Columbia, 2006)
During stressful periods, glucocorticoid production is increased. Glucocorticoid metabolites are found in blood, urine and feces. Our first goal was to determine if fecal glucocorticoid metabolite (FGM) measurements are a ...
Ambulatory assessment of physical pain, emotional distress, and alcohol use
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The available research suggests that many individuals with chronic pain drink alcohol to manage their pain. However, few studies have examined the association of alcohol and pain...
Factors influencing use of split-lines of credit and internal capital rationing among PCA borrowers
(University of Missouri--Columbia, 1984)
Farmers’ use of credit has been studied extensively because debt capital is an integral part of present-day agricultural financial management. However, very little is known about split-lines of credit or multiple sources ...
Establishing Metronidazole as a Novel Biomarker of CYP2A6 Activity
(University of Missouri -- Kansas City, 2018)
CYP2A6 is a polymorphically expressed enzyme with variation associated with
smoking behavior, cessation success, lung cancer risk, and differential drug exposure to
numerous medications including anti-infectious and ...
Agent-based modeling of the spread of the 1918-1919 Spanish Flu in three Canadian fur trading communities
(University of Missouri--Columbia, 2006)
In this project, an agent-based computer simulation was developed to model the spread of the 1918-1919 influenza pandemic within and among three Aboriginal communities in central Manitoba. Data from model simulations ...
A study of types of farming in the U.S. by the farm management survey method
(University of Missouri--Columbia, 1919)
The following study was made to get an insight into the conditions and farm practices of six different types of farming in the United States from the standpoint of farm management. Previous work along this line indicates ...
Woody species and forest structure in northern Missouri riparian forests with different ages and watershed sites
(University of Missouri--Columbia, 2006)
A chronosequence (1 to 250+ years) of 160 woody species plots was established throughout northern Missouri riparian forests to explain the influence of site hydrology and stand age on species distribution and forest structure. Stand age was found...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
populations in Missouri.The results of my dissertation research indicate that the quantity and quality of terrestrial habitat available to pond-breeding amphibians can have substantial population level consequences including increased extinction probabilities...
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)
.e. an aquatic-terrestrial zone (ATTZ), within the main channel of the lower Missouri River. Predictive models of sandbar morphometry (area, wetted perimeter, elevation, and water-surface slope) were developed to determine how changes in discharge affect...
On the ability of rocks to conduct heat in the Lithosphere
(University of Missouri--Columbia, 2019)
This work focuses on creating a model for the conductive thermal transport properties of rocks using measured thermal diffusivity (D) with the Laser Flash Analysis (LFA) method, which eliminates common errors associated ...
Subjective-objective sleep discrepancy in older adults : examining the roles of cognition and arousal
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] The difference between subjective (self-report) and objective (e.g., polysomnography, wrist-worn wearables) measures of sleep is referred to as subjectiveobjective sleep discrepancy (SOSD) and ...
Establishing mostly-male bluegill groups and evaluating their growth benefits in indoor rearing systems
(University of Missouri--Columbia, 2007)
Male bluegill have the greatest potential to reach food market size ([greater than or equal to] 0.5 lb.; 225g) within two growing seasons. However, establishment of monosex, juvenile bluegill groups does not currently ...
Trait anxiety : a psychometric shadow
(University of Missouri--Columbia, 1978)
The purpose of the present study is to examine the independent relationships which trait and state anxiety have to measures of fear in rat-phobic female college students during imagined and live encounters with a member ...
Structure and Mechanical Properties of Cement and Intermetallic Compounds via ab-initio Simulations
(2015)
Calcium silicate hydrates comprise a class of minerals formed synthetically during Portland cement hydration or naturally through various geological processes. The importance of these minerals is immense since they are the ...
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...
Environmental drivers of Northern bobwhite fall and winter survival and resource selection in Southwest Missouri
(University of Missouri--Columbia, 2020)
, while there was a negative effect of grass on winter resource selection. Woody cover was an important component of vegetation contributing to fall and winter survival and resource selection of bobwhite in Missouri. More specifically, proximity to shrubs...
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 ...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
Agriculturally produced ethanol, a renewable resource, may be reformed noncatalytically into hydrogen by a novel process utilizing supercritical water, which acts synergistically both as a solvent and as a reactant. By ...
Landscape and inchannel factors affecting the distribution and abundance of riverine smallmouth bass in Missouri
(University of Missouri--Columbia, 2008)
