The role of genetic and phenotypic diversity in maize and its effects on aflatoxin accumulation by the fungus Aspergillus flavus
(University of Missouri--Columbia, 2008)
Accumulation of the potent carcinogen, aflatoxin, in maize poses a significant health risk to humans and animals. Most commercially grown maize lines are susceptible to infection by the fungus that synthesizes aflatoxin, ...
Characterization of an in vitro neural stem cell niche with educational component : stem cells and society
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] We describe a novel neural stem cell (NSC) culture system, derived from embryonic stem (ES) cells, that maintains and expands a population of neural stem cells similar to those...

Effects of a self-care deficit nursing theory-designed nursing system on sympton control in children with asthma
(University of Missouri--Columbia, 2001)
Asthma is the most frequent reason for preventable hospital admissions among children regardless of race or socio-economic status. Since asthma hospitalizations are preventable, an implicit assumption is that parents are ...
Investigation of the replacement of cysteine residues in DOTA-(Tyr³)-octreotate: synthesis, characterization and evaluation of biological activities
(University of Missouri--Columbia, 2006)
Modification of the peptide sequence of DOTA-Tyr³-octreotate is carried out by substituting the cysteine moieties with D-Cysteine, L-Penicillamine and D-Penicillamine in one or both positions to study the effect of this ...
Fertilizer effects on soil pH, soil nutrients, and nutrient uptake in swamp white and pin oak seedlings on an alkaline Missouri River bottomland
(University of Missouri--Columbia, 2008)
There is growing interest among forest and wildlife managers in the reforestation of bottomlands with mast producing hardwoods in the Lower Missouri River and Mississippi River Alluvial valleys. However, it is common for bottomland hardwood...
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 ...
Semiparametric analysis of panel count data
(University of Missouri--Columbia, 2007)
Panel count data often arise in long term studies that concern occurrence rates of certain recurrent events. In such studies, each subject is observed only at finite discrete time points instead of continuously, and only ...
Studies on the nucleophilic substitution reactions of a dimeric cyclopentadienone
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nucleophilic substitution reactions of 3,5-Dibromo-3a,4,7,7a-tetrahydro-4,7-methano-indene-1,8-dione (48) have been studied. Amines, thiols and alcohols have been employed...
The effects of supplemental anionic salts & yeast culture on the production of dairy cattle during the periparturient period
(University of Missouri--Columbia, 2006)
The objective of this thesis was to determine nutritional strategies with the strategic use of feed additives during the periparturient period to reduce the negative energy balance as the dairy cow transitions from late ...
Geotextile wrap-face wall using marginal backfill
(University of Missouri--Columbia, 2006)
be developed and implemented. A geotextile wrap-face wall was chosen to reinforce the soil mass behind the existing concrete wall, which now acts as a façade. The in-situ soil (CL), a marginally suitable material, was used for the backfill. Extensive drainage...
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 ...
Occupancy modeling of forest carnivores in Missouri
(University of Missouri--Columbia, 2008)
My research used infrared remote cameras, trackplate boxes, and scat transects to survey for carnivores at 53 sites throughout the southern forested region of Missouri. Cameras and track-plates both detected Eastern spotted skunk (Spilogale putorius...
Desegregation and its impact on institutional culture at a historically black university
(University of Missouri--Columbia, 2009)
In this case study, 38 Black and White participants shared their recollections of intergroup contact during the first 15 years of desegregation (1954-1969) at a Historically Black University in a predominantly White Midwestern community. Faculty...
Modeling of selective laser sintering of single-component metal powders
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Selective Laser Sintering (SLS) is a rapid prototyping technology which enables freeform fabrication of complex-geometry components directly from three-dimensional CAD data...
Sensor characterization for long-term remote monitoring of bridge piers
(University of Missouri--Columbia, 2007)
Structural instability of bridge piers resulting from scour or other natural hazards can lead to bridge collapse. A monitoring system that analyzes bridge pier behavior could prevent this type of failure by detecting ...
Experimentally assessing the influence of resource availability and social aggregation on the parasites of raccoons
(University of Missouri--Columbia, 2009)
I investigated how experimental increases in social aggregation and resource availability affected ectoparasite prevalence and intensity (number of parasites on infested hosts only) and endoparasite species richness of ...
