The politics of CO2 emissions
(University of Missouri--Columbia, 2020)
in responding to tackling climate change problems. Therefore, investment and strategic intervention for maintaining institutional quality and adopting institutional reform where needed merit more in-depth research initiatives....
Three essays on the economics of pesticide use
(University of Missouri--Columbia, 2022)
Pesticides primarily benefit humans in terms of protection of food production, prevention of diseases, and weed control, but also potentially harm people and the environment. Given increasing current interest in human health and environmental...
Studies of ruminant digestion, ecology, and evolution
(University of Missouri--Columbia, 2008)
This thesis examines ruminant digestion, ecology, and evolution, particularly where they can improve livestock production systems. We performed an experiment that estimated ruminal in situ degradation parameter values of ...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
A stem analysis was perform to examines the effects of thinning treatments on Melina (Gmelina arborea) wood quality and tree architecture in the North Coast of Colombia. 27 plots under forest management regimes and age classes were evaluated. Split...
Modeling and analysis of nonlinear biological systems
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation focuses on the modeling and analysis of a set of biological phenomenon at a cellular (Part I) and systems (Part II) level. In Part I, the development...
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 ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...
Development and application of vegetative buffer width modeling using geographic information systems
(University of Missouri--Columbia, 2009)
of performance could potentially require wider or narrower buffer widths in order to meet certain stormwater management criteria. This method was successfully demonstrated within the LaBarque Creek watershed located southwest of St. Louis, Missouri for three...
Exploring the impact of peracetic acid on bacterial regrowth and plasmid release and developing a novel whole-cell biosensor to monitor the expression of quorum sensing genes
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Peracetic acid (PAA or CH3COOOH) is a promising alternative to chlorine-based disinfectants for water and wastewater treatment due to its strong antimicrobial properties and low...
Early detection of health changes in the elderly using in-home multi-sensor data streams
(University of Missouri--Columbia, 2022)
The rapid aging of the population worldwide requires increased attention from health care providers and the entire society. For the elderly to live independently, many health issues related to old age, such as frailty and ...
Investigation of K₀ NAA at MURR and investigation of the toenail as a biomonitor for Mg, Zn, Cu, Se and Hg
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Chapter 1: The K[subscript 0] method of neutron activation analysis (INAA) requires a stable core and neutron flux parameterization. The stability of the reactor core at MURR...
An empirical approach to exploring the role of selective incentives in mitigating the free rider problem
(University of Missouri--Columbia, 2007)
The concept of free riding has been recognized as a challenge facing collective action organizations for centuries. However, the term free riding has been used to describe a range of alternative problematic actions and ...
Clinical deterioration and perception of cues among medical surgical nurses
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In the medical-surgical setting, failure to rescue events continue to remain prevalent. While failure to rescue events are often proceeded by changes in patient cues (i.e. vital...
Neonatal beef calf morbidity and mortality in Missouri
(University of Missouri--Columbia, 2022)
on necropsy findings in neonatal beef calves presented to the University of Missouri's Veterinary Medical Diagnostic Laboratory and one prospective study conducted on critically ill neonatal beef calves presented to the University of Missouri's Food Animal...
High valent uranium dioxo and imido complexes : synthesis and structure
(University of Missouri--Columbia, 2008)
. Whereas high oxidation state ions dominate environmental speciation, the corresponding high-valent organometallics are rare. These hexa- and pentavalent ions are often stabilized by the isoelectronic oxo or imido ligands, which result in robust molecular...
Measuring and comparing the spatiotemporal evolution of accident hot spots
(University of Missouri--Columbia, 2022)
One reality of transportation systems is that vehicular accidents can happen practically anywhere and at any time. An increasing body of research suggests though that spatial and/or temporal dependencies (i.e., clusters ...
