Establishment of native plant species for livestock forage in silvopasture systems
(University of Missouri--Columbia, 2022)
the cool season grasses. All remaining forages were no-till drilled each winter prior to the growing season. Environmental (PAR, ambient temperature, soil water content), plant community composition, herbage accumulation, and forage quality data were...
Kinetics, mass transfer, and mass re-equilibrium for arsenate adsorption on iron oxide-based carbons
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Removal of arsenic (As) from drinking water sources is much needed worldwide, and small water treatment systems, such as point-of-use (POU) treatment, could be an effective...
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 ...
Evaluating phytochemical contributions to atrazine degradation
(University of Missouri--Columbia, 2020)
Surface water contamination from the herbicide atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) has been a concern for many years. The use of vegetated buffer strips (VBS) is known to improve water quality but the use of specific...
Design of global sustainable supply chains
(University of Missouri--Columbia, 2019)
, is integrated with national environmental and social impacts to construct a triple bottom line (3BL) approach by industrial sectors. This model supports decision making by including both direct impacts, as well as indirect impacts, associated with upstream...
The effect of the degree of slope and rainfall characteristics on runoff and soil erosion
(University of Missouri, College of Agriculture, Agricultural Experiment Station, 1938)
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 ...
Impacts of soil management practices on soil fertility in potato-based cropping systems in the Bolivian Andean highlands
(University of Missouri--Columbia, 2010)
Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in ...
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...
Multi-hazard resilience assessment of river-crossing bridges
(2021)
Bridge structures are required to possess high reliability and robustness against the concurrent effect of extreme loads and environmental attacks. To achieve such interrelated goals, it is necessary to assess the system performance and resilience...
Impact of woody biomass production and biopower generation on US forests
(University of Missouri--Columbia, 2022)
This dissertation presents a study of environmental impact of woody biomass production and consumption on the eastern US forests. The first part is concerned with the impact of the exponential growth in trading of US pelletized wood fibers triggered...
Factors affecting neonatal and peripartum maternal metabolism and behavior in beef cattle and horses
(University of Missouri--Columbia, 2018)
characteristics, maternal and neonatal metabolic status, and colostrum quality were examined in beef cattle. Calves born to multiparous dams had greater birth weight and tended to have larger placentas. Protein was greater and lactose tended to be less...
Synthesis, characterization, and reactivity of actinide complexes bearing An-E bonds (An = Th, U; E = P, As)
(University of Missouri--Columbia, 2021)
Organoactinide complexes bearing An-E (An = Th, U; E = P, As) bonds were synthesized and reactivity studies were performed with various unsaturated and industrially/environmentally relevant small molecules in an effort to elucidate further...
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...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
Over 500 million people live in proximity of an active volcano globally. Although lava flows rarely endanger human life, they often destroy critical infrastructure. Advancing our understanding of lava flow dynamics is ...
Long Term Ocular Drug Delivery with Novel Pentablock Copolymers; Part I: Composite Nanoformulation of Macromolecules For Back of the Eye Diseases, Part II: Dexamethasone Nanoparticle to Develop an In Vitro Model for Glaucoma
(University of Missouri -- Kansas City, 2017)
Pentablock (PB) copolymers have been successfully synthesized for long term delivery in
the treatment of posterior segment ocular diseases. PB copolymers are comprised of FDA
approved biodegradable polymer such as ...
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...
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...
