Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
was determined for a 1.2-m soil profile (PAW[subscript 1.2]). Plant-available water fraction values of 0.23 and 0.12 were used for the topsoil layer (assumed to be silt loam) and subsoil layer (assumed to be silty clay) textures, and the boundary between the two...
Relative motion of spheroids at low Reynolds number
(University of Missouri--Columbia, 1987)
"The term aerosol has been frequently used to describe microscopic liquid and/or solid particles. Initially aerosol particles were thought to be stable when settling in a gravitational field. Later Brownian motion and ...

(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The purpose of this study was to examine the relationship between Academic Progress Rate and team, athletic department, and institutional characteristics. ...
Effects of continous administration of low-dose of Escherichia coli lipopolysaccharide in chicks and poults fed non toxic doses of aflatoxin B1 and T-2 toxin
(University of Missouri--Columbia, 2005)
Six studies (three with broilers and three with turkeys) were conducted to determine if E. coli lipopolysaccharide (LPS) would enhance the effects of aflatoxin B1 (AFB1) and the T-2 toxin (T-2) in chicks and poults fed ...
Utilizing unoccupied aerial systems and artificial intelligence for monitoring nonbreeding waterfowl abundance in Missouri
(University of Missouri--Columbia, 2023)
of Conservation wetland conservation areas October - February 2021-2022. Helicopter surveys were flown using an Airbus H125 helicopter at altitudes of 100 - 350 m, with UAS surveys flown using a DJI Mavic 2 Pro UAS at 15 - 90 m. Waterfowl behavior was categorized...
Investigating denitrification from two Missouri claypan soils
(University of Missouri--Columbia, 2020)
system. In addition, soil denitrification potential, under non-limiting conditions, was determined on 90 m-grid samples collected from the fields. Potential and actual denitrification rates were not significantly different between fields, but potential...
Photosynthesis and heat tolerance of soybean
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Photochemical Reflectance Index (PRI) is determined from canopy spectral reflectance measurements and can provide important information about ...
Three essays on crime policy and the Bayesian bootstrap
(University of Missouri--Columbia, 2021)
This dissertation consists of three chapters. In the first chapter, I analyze credible intervals for quantiles constructed using Bayesian bootstrap techniques and show that credible intervals constructed using the ...
Impacts of artificial light and melatonin signaling pathways on behavior and skeletal physiology in mice
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The natural cycles of light and darkness are a major feature of the environment for most species; thus, circadian physiology is rooted in the expectation ...
Hiding in plain sight : camouflage in the corporate governance of IPOs
(University of Missouri--Columbia, 2012)
I show that quality of corporate governance incrementally explains IPO pricing and performance. I facilitate this by creating a measure of corporate governance, provided by the bylaws and charter of an IPO, called camouflage. ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
The vital rates (e.g., survival, growth, and reproduction) of distinct life stages within a species are known to influence the growth and persistence of populations. As such, studies describing stage-specific vital rates, ...
Motivation for smoking and smoking cessation : a self-determination theory investigation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nicotine dependence is conceptualized as a disorder of motivation. Initial drug use is goal-directed, but with the development of dependence it becomes ...
