Application of hyperspectral remote sensing in detecting and mapping Sericea lespedeza in Missouri
(University of Missouri--Columbia, 2007)
When conservationists in Missouri realized that sericea lespedeza was taking its toll by threatening the healthy growth of economic vegetation, they decided to start controlling the invasion of this species. A major challenge ...
Structure of an antigen-binding fragment bound to stem-loop DNA and crystallization of recombinant haemophilus influenzae e(P4) acid phosphatase
(University of Missouri--Columbia, 2006)
DNA-1 and 11F8 are anti-ss DNA antibodies derived from autoimmune lupus-prone mice. They are very similar to each other in terms of CDR sequence and preference for binding T-rich ss DNA. G1-17 is an oligonucleotide identified ...
The application of phytolith and starch grain analysis to understanding formative period subsistence, ritual, and trade on the Taraco Pennisula, Highland Bolivia
(University of Missouri--Columbia, 2006)
This thesis employs microfossil data to add to our understanding of three factors (agricultural intensification, ritual, and trade) viewed as critical in the development of the Tiwanaku state during the preceding Formative period (1500 BC-AD 400...
Overstory density and its effect on oak regeneration abundance and oak understory height growth in the Missouri Ozark Highlands
(University of Missouri--Columbia, 2008)
This study examined how overstory density affects regeneration abundance and understory height growth in the Missouri Ozark Highlands. Data were collected on three different treatment types, no harvest management, uneven-aged ...
Seasonal variation in nutrient availability and uptake by oak saplings following four nitrogen treatments on Missouri River floodplain
(University of Missouri--Columbia, 2008)
Bottomland restoration of native hardwood species provides a variety of benefits to the environment and the landowners. However, when reforesting agricultural floodplains along the Missouri River, high soil pH often causes nutrient deficiencies...
A custom oligonucleotide microarray analysis as a tool for dissecting soybean-bradyrhizobium japonicum nodule senescence
(University of Missouri--Columbia, 2007)
compounds from the plant, and the plant receives reduced nitrogen, the most limiting nutrient in agriculture for the synthesis of proteins, amino acids, nucleotides and vitamins. Most investigations on this symbiosis concern the formation of nodules whereas...
Manganese nutrition and photosynthesis in NAD-malic enzyme C-4 plants
(University of Missouri--Columbia, 2008)
NAD-ME activity and the continued supply of CO2 to bundle sheath cells. The objective of this research was to determine the Mn requirement for optimum photosynthesis and plant biomass production for two agriculturally important NAD-ME C-4 species...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
Agriculturally produced ethanol, a renewable resource, may be reformed noncatalytically into hydrogen by a novel process utilizing supercritical water, which acts synergistically both as a solvent and as a reactant. By utilizing supercritical water...
Effects of prescribed burning in Missouri Ozark upland forests
(University of Missouri--Columbia, 2007)
Prescribed fire is used in Missouri to achieve various silvicultural goals, but the use of burning in upland Ozark forests raises many questions that research has yet to answer. The purpose of this study is to examine the ...
Nanoporous carbon from corn cobs and its application
(University of Missouri--Columbia, 2007)
Chemical activation of corn cobs using phosphoric acid or potassium hydroxide can lead to nanoporous carbon having surface area in excess of 3800 m²/g and pore volume of 2.5cc/g. Dried, crushed, corn cobs were carbonized ...
Spatial econometric analysis of highway and regional economy in Missouri
(University of Missouri--Columbia, 2006)
The dissertation consists of four chapters: first, highway and economic development; second, spatial effects of highways and employment in Missouri; third, highway and industrial establishment in Missouri; finally, ...
Variations in the perceptions of urban canals in Fresno, California
(University of Missouri--Columbia, 2008)
In the fertile but dry San Joaquin Valley in California, Irrigation canals serve as the life blood of the agricultural industry. These canals predate urbanization and the expansion of cities in the valley have incorporated canals as de facto...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
Traditional soil mapping concepts do not sufficiently address the spatial resolution of some soil management problems. Continuous models of soil profiles and landscapes are needed to move beyond the categorical paradigm ...
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 ...
Beyond money : relating local school taxation to family and community risk
(University of Missouri--Columbia, 2007)
State school finance systems have typically required some local tax effort to determine how to dole out state funds to provide equitable and adequate educational opportunities for K-12 students. As state-level systems have ...
Substrate activation in the urate oxidase reaction
(University of Missouri--Columbia, 2008)
The enzyme urate oxidase (UO) is involved in nitrogen metabolism of many organisms. Urate oxidation is carried out by UO without the aid of a metal ion or cofactor. A catalytic diad has previously been proposed to be ...
Structural studies of glyceraldehyde-3-phosphate dehydrogenase complexes and the E. coli PutA DNA binding domain
(University of Missouri--Columbia, 2006)
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a glycolytic enzyme that catalyzes the formation of 1,3-bisphosphoglycerate from glyceraldehyde-3-phosphate. We have solved a high-resolution (1.75 Å) structure of a ...
Fire risk assessment of the western portion of the central hardwoods forest region
(University of Missouri--Columbia, 2008)
This study examined how fire risk, a combination of fuels conditions and fire probabilities, varied across a large portion of Missouri, Illinois, and Indiana. Case studies were conducted to evaluate the fuel loading ...
Identification and characterization of glyphosate-resistant common ragweed
