Patterns of local mobility in an Iban community of West Kalimantan, Indonesia
(University of Missouri--Columbia, 2008)
This study examines the concept of mobility in relation to small-scale, subsistence-oriented societies, in which groups and individuals create complex resource networks in order to satisfy physical and social needs. Mobility ...
Protection, production, prosperity : Costa Rican farmers respond to the windbreaks project
(University of Missouri--Columbia, 2008)
In 1991 and 1992, farmers in Monteverde, Costa Rica participated in a reforestation project that involved installing windbreaks. The project was implemented by a local conservation organization. This thesis aims to add to ...
Phenotypic modulation of vascular smooth muscle cells : evidence for a role of the G protein-coupled P2y2 receptor
(University of Missouri--Columbia, 2008)
G protein-coupled receptors regulate two major functions of vascular smooth muscle cells (SMCs) - the vasomotor contractile response and the proliferative response. The contractile phenotype of SMCs has mainly been studied ...
A study of SecA : the motor of the bacterial secretion system by site-directed spin labeling and EPR
(University of Missouri--Columbia, 2008)
For more than 3 decades, the biochemical details of the Sec system of protein export have been teased out of Escherichia coli. Through these efforts we know that SecA, the ATPase of the Sec system, interacts with several ...
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...
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...
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 ...
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 ...
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 ...
Three essays in regional economic modeling
(University of Missouri--Columbia, 2008)
My dissertation is about regional economic modeling for understanding local economy, economic impact analysis and forecasting. In the first essay, I developed a nonspatial version of community policy analysis model for ...
Restoring forest composition and structure of riparian corridors in the Missouri Ozarks
(University of Missouri--Columbia, 2008)
bottomland agricultural fields. These afforestation practices most often consist of planting bare-root tree seedlings of a select number of hardmast species and managing vegetation with a number of pre- and postemergent herbicides, or planting a perennial...
Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...
Identification, characterization, and management of glyphosate-resistant waterhemp (Amaranthus rudis sauer.) in Missouri
(University of Missouri--Columbia, 2008)
The possibility of in waterhemp has been of concern to Midwest corn and soybean producers due to a heavy dependence on glyphosate as a weed control tool and the increased incidence and problematic nature of waterhemp in ...
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of ...
Design and construction of helmholtz coil for biomagnetic studies on soybean
(University of Missouri--Columbia, 2008)
germination. Results have also shown that magnetic fields influence soybean germination more than electromagnetic fields from an anechoic chamber and a TEM cell. The magnetic field may provide a feasible non-chemical solution in agriculture, and thus offers...
Fertilizer effects on soil pH, soil nutrients, and nutrient uptake in swamp white and pin oak seedlings on an alkaline Missouri River bottomland
(University of Missouri--Columbia, 2008)
There is growing interest among forest and wildlife managers in the reforestation of bottomlands with mast producing hardwoods in the Lower Missouri River and Mississippi River Alluvial valleys. However, it is common for ...
Methodology for quantifying wetland landscape parameters for highway right of way decisions utilizing GIS
(University of Missouri--Columbia, 2008)
Wetlands are a type of habitat which forms an interface between aquatic and terrestrial ecosystems. A growing problem in the state of Missouri and around the nation is the loss of the natural wetlands due to the expansion ...
