Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
and landscape position, intact soil core samples (76 by 76 mm) were taken from the 0- to 10-, 10- to 20-, and 20- to 30-cm soil depths. For objective 2, soil profile samples were taken at 18 to 19 locations from each of two close-by fields and PAW capacity...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
/Environmental eXtender (APEX) model was calibrated and validated for a 32-ha field from 1993 to 2002 for runoff, sediment, and atrazine loads. Two indices were developed using soil property and topography data, the Conductivity Claypan Index (CCI) and the Claypan...
Simulation and experimental study of the multichanneling rimfire gas switch
(University of Missouri--Columbia, 2005)
Since 1985, the Rimfire switch has been used extensively in accelerators at Sandia National Laboratories. Demands for increased future accelerator performance require improvements to the Rimfire switch. This thesis is both a theoretical...
The role of genetic background on the phenotypic severity of the osteogensis imperfecta murine (oim) COLIA2 gene mutation throughout postnatal development
(University of Missouri--Columbia, 2006)
Osteogenesis imperfecta (OI) is a diverse disease of type I collagen, the main structural protein in the body. It has been well documented that related individuals harboring the same OI-causing mutation can have very ...
Use of non-lethal endpoints to establish water quality requirements and optima of the Topeka Shiner (notropis topeka)
(University of Missouri--Columbia, 2017)
Water quality influences growth, development, and physiology of aquatic vertebrates. Current criteria on water quality assessments are primarily based on lethal level experiments (e.g. LC50 tests), which are poorly suited ...
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. ...
Regression analysis of interval-censored failure time data with non proportional hazards models
(University of Missouri--Columbia, 2018)
sieve maximum likelihood procedure. In particular, an EM algorithm is developed and the resulting estimators of regression parameters are shown to be consistent and asymptotically normal. An extensive simulation study was conducted for the assessment...
Mathematical problems from cryobiology
(University of Missouri--Columbia, 2009)
Cryobiology is the study of life anddeath at low temperatures and provides a fascinating setting for applied mathematics. The interdisciplinary nature of cryobiology mirrors the diversity of applications ranging from animal ...
Development of an integrated approach combining artificial neural network material based on modeling with finite element analysis of forming processes
(University of Missouri--Columbia, 2005)
The use of a finite element model for design and analysis of a metal forming processes is limited by the incorporated material model's ability to predict deformation behavior over a wide range of operating conditions. ...
Three essays on corporate-political relationships
(University of Missouri--Columbia, 2018)
This study examines the effect of corporate-political relationships on corporate decision making, performance, and value. In the first essay, presented in Chapter 3, I examine whether defendant firms use their political ...
Radioanalytical multi-elemental analysis : new methodology and archaeometric applications
(University of Missouri--Columbia, 2010)
Several projects are covered in this dissertation: the application of instrumental neutron activation analysis (INAA) and rigorous statistical analyses to the sourcing of Egyptian limestone and Kenyan obsidian, and the ...
Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)
Automated sensing of soil macronutrients (i.e., N, P, and K) would allow more efficient mapping of soil nutrient variability for variable-rate nutrient management. This study reports on the development of a sensor array ...
