[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Men are more willing to take risks and invest more in stocks than women. Do gender differences with respect to risk tolerance still exist within married and cohabiting couples...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
Soybean (Glycine max L. Merrill) is one of the most important legume crops grown worldwide. However, without phosphorus (P) fertilization, soybean yields often are limited by phosphorus availability. Phosphorus is an ...
Emplacement styles of obsidian lavas: an integrated field and laboratory study
(University of Missouri--Columbia, 2021)
Previously accepted models of emplacement dynamics of obsidian lavas have recently been called into question by observations made during the effusive eruptions of Chaiten in 2008-2009 and Cordon Caulle in 2011-2012 in ...
Using metabolic and biochemical characteristics of postmortem muscle to investigate the interconnectedness of beef color, flavor, and tenderness
(University of Missouri--Columbia, 2021)
Understanding relationships between beef palatability and quality components are crucial for continued production of high quality and consistent beef products. Myoglobin concentrations at 48 and 336 h resulted in moderate, ...
Reflux, aspiration and respiratory disease in dogs : clinical consideration and advances in aerodigestive diagnostics
(University of Missouri--Columbia, 2019)
The aspiration of gastric contents into the respiratory tract has been associated with the development and progression of multiple respiratory diseases in humans. In veterinary medicine the term "aspiration" is considered ...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
. In urban environments they feed upon dead wood, and therefore infest and destroy man-made wooden structures. Missouri is considered to have a moderate risk for termite infestations when compared with the states of the southeast part of the country. Despite...
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...
Pottery production at Fort Hill (27CH85) a seventeenth-century refugee community in northern New England
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This thesis formulates a model for explaining stylistic, functional, and compositional diversity in ceramic artifacts produced during the contact period (A.D. 1590...
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...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
This project comprises several chemical routes to produce soy-based polyols for future use in polyurethane foam applications. Soybean oil was polymerized by heat and catalyst to increase molecular weight, and viscosity for ...
Investigating the bifunctional chelate approach for radiopharmaceutical development
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Radiopharmaceuticals are drugs that contain a radioactive atom for the purpose of imaging or therapy of disease. The type of emission determines the applicability for each drug...
Detection and modeling of bat species occupancy at multiple scales across a forested landscape in southeastern Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Populations of forest dwelling bats have been in decline in recent years, and have therefore become increasing foci in forestry research efforts. Difficulty in bat species...
Flexure shear response in fatigue of fiber reinforced concrete beams with FRP tensile reinforcement
(University of Missouri--Columbia, 2007)
of polypropylene fibers by volume, individual compressive tests were performed on both lab-mix and ready mix concrete specimens. In the lab, concrete mixes with 0.0%, 0.5%, and 1.0% by volume, fibrillated polypropylene fibers were produced. Along with these...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The environment was altered...
Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
Mississippi Valley-type (MVT) deposits represent enrichments of base metals and other elements up to 1000's of times greater than their average concentrations in the Earth's crust. These enrichments most commonly consist ...
