Quantifying suspended sediment loading in a mid-Missouri urban watershed using laser particle diffraction
(University of Missouri--Columbia, 2011)
/water-quality stations were installed in a nested-scale watershed study design to capture differing land-use type influences on SSC. Mean SSCs were estimated to be 66.0, 70.0, and 86.0 [mu]l/l for the headwater (agricultural), suburban (mixed land-use), and urban sub...
Assessment of Seismic Hazards along the Northern Gulf of Aqaba
(2014-09-26)
zones, and several transverse faults. The integration of offshore and onshore data confirm the extension of these faults along both sides of the Gulf of Aqaba. A 3D model of GPR data at one site in Aqaba indicates that the NW-trending transverse faults...
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...
Behavioral choice and demographic consequences of wood frog habitat selection in response to land use
(University of Missouri--Columbia, 2007)
microhabitats by radio-tracking 117 frogs over 3 years. I documented 29 predation events, 13 desiccation events, and 8 mortalities of unknown cause. Using Coxproportional hazard models, I found that survival within the timber harvest array was 1.7 times lower...
Analysis of factors influencing loan losses of production credit associations
(University of Missouri--Columbia, 1974)
reflecting the production and market factors and associated risks, outside business interests that interacted with the kind of enterprise to produce a differential effect on loan losses, and finally, the interaction between education and farming experience...
The Ebb and flow of policy, economics, and science: an analysis of policy drivers in the Missouri River Basin
(2013)
The Missouri River basin underwent a major transformation when the United States Congress approved the Flood Control Act of 1944 and the Bank Stabilization and Navigation Project of 1945. Generations removed from those national policy decisions...
Geostatistical analysis of land use/land cover changes and population growth trends in the Komadugu-Yobe River Basin in Nigeria
(University of Missouri-Kansas City, 2012-06-14)
The Komadugu-Yobe River located in northeastern Nigeria is an important tributary of Lake Chad. Since the 1970s, the Komadugu-Yobe basin has experienced significant changes in population density and land use/land cover. ...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
as to the aggregate data for all 86 stations, resulting in an analysis of 130,986 observations of 24-hour precipitation. Soundings were then constructed for each using the 3-hourly North American Regional Reanalysis (NARR) gridded datasets. From these individual...
Land cover classification from satellite imagery, and its applications in cellular network planning
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] To further increase the classification accuracies, radar image processing techniques were investigated to preprocess the Radarsat data before classification. Eight processing...
Development of Aerial-Ground Sensing Network: Architecture, Sensor Activation, and Spatial Path-Energy Optimization
(University of Missouri -- Kansas City, 2019)
The advent of autonomous navigation, positioning, and in general robotics
technologies has enabled the maturity of small to miniature-sized unmanned aerial
vehicles (UAVs; or colloquially called drones) and their wide ...
Agroforestry and cover crops for improving surface water and groundwater quality
(University of Missouri--Columbia, 2023)
Unsustainable agricultural practices and the rapid expansion of agricultural lands to satisfy the food demand of the growing world population have caused significant sediment, and nutrient losses from agricultural fields, harming the environment...
Waterproof dress : an exploration of development and design from 1880 through 1895
(University of Missouri--Columbia, 2009)
Waterproof dress had an important role in the late nineteenth century. Heretofore little research has been done to examine the development and design of this apparel sector. The three types of waterproofing techniques used ...
Plant community response during establishment of woodland silvopasture in the Missouri Ozarks
(University of Missouri--Columbia, 2022)
Disturbance-mediated oak (Quercus spp.) woodlands were formerly a prevalent community type in Missouri, and their restoration is a key objective of land management agencies and conservation organizations. Over one-third of wooded land in Missouri (2...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
and germination of poison hemlock seed were measured. Dry biomass of poison hemlock was measured through time in the early spring in relation to plant density. Herbicide efficacy experiments were conducted in the spring using amino acid biosynthesis inhibitors...
Development and evaluation of pattern recognition habitat models for the ruffed grouse, gray squirrel, and fox squirrel in Missouri
(University of Missouri -- Columbia., 1987)
Pattern recognition (PATREC) models are single-species models that use habitat characteristics to arrive at an estimation of population abundance. Currently, personnel of the Mark Twain National Forest in Missouri are using this type of model as a...
What is the impact of livelihood strategies on farmers' climate risk perceptions in the Bolivian highlands?
(University of Missouri--Columbia, 2009)
The Andean Highland region in Bolivia possesses a harsh climate environment that is highly variable. This study combines risk perception literature and livelihood strategy literature to examine climate risk perceptions. ...
Uneven-aged management in the Missouri Ozarks: effects of site conditions, stand density, and prior populations on oak regeneration
(University of Missouri--Columbia, 2022)
While studies have shown the importance of site characteristics and overstory density on the success of white oak regeneration under uneven-aged management, few studies have analyzed the effects of these variables over time in the Missouri Ozarks...
Development of a multi-omics approach to identify highly correlated transcriptomic, proteomic and metabolic signatures in maize B73 and FR697 drought stressed nodal roots
(University of Missouri--Columbia, 2021)
