Dairy Waste Management Systems in Missouri (2004)
(University of Missouri--Columbia. Extension Division, 2004)
Missouri dairy manure management can be classified into three systems -- solid, slurry or lagoon -- depending on the collection, transportation and distribution of manure on the fields. These systems are dependent on the amount of bedding and water...
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 ...
Adoption of nutrient management practices
(University of Missouri--Columbia, 2008)
Off-farm income has recently been incorporated into the analysis of technology adoption, due to its increasing share in total farm household income in the U.S. Previous studies, however, found inconsistent results with ...
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 ...
A formal evaluation of storm type versus storm motion
(University of Missouri--Columbia, 2008)
, and subsequently, forecast for motion. This publication focuses on identifying the ambient environmental characteristics typical of several types of severe convective storms. Three types of severe convective storms are examined: supercell, linear, and multicell...
The role of household environment on health outcomes for female adolescents in Kenya
(University of Missouri--Columbia, 2007)
; those between the ages of 20 and 24 comprised nearly half (over 47%) of the sample. This study found a strong association between reported illness and environmental factors in the household. Age and marriage were highly significant factors, producing a...
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...
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...
The synthesis and characterization of 1,1'-disubstituted ferrocene imine Schiff base ligand systems for use as potential environmental heavy metal cationic sensors
(University of Missouri--Columbia, 2008)
through three means: proton nuclear magnetic resonance (1H NMR), ultraviolet-visible spectroscopy (UV-Vis) and cyclic voltammetry (CV). While a working universal heavy metal sensor was not achieved during this research project, it advanced the progress...
The culture wars & political polarization in perspective : why polarization and its perturbations are a persistant [i.e., persistent] puzzle in political science
(University of Missouri--Columbia, 2009)
Political polarization in the American electorate has received a great deal of attention in recent years with most of the research focusing on social issues and their impact on electoral outcomes. However, scant attention ...
