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...
Composition of soil as affected by different cropping systems
(University of Missouri--Columbia, 1913)
Among the experiments in soil fertility which are being carried out by the University of Missouri College of Agriculture is a series of plot experiments which have been in progress since 1889. There are thirty-nine plots in the field and each has...
Minimum milk requirement for calf raising
(University of Missouri--Columbia, 1919)
The dairyman is keenly interested in knowing how he can raise his calves in an economical and successful manner. This thesis reports the results of several experiments in early weaning and minimum use of milk for calf rearing, which constitute part...
Effects of plastic mulch, row cover, and cultivar selection on growth of tomatoes (Lycopersicon esculerntum Mill.) in high tunnels
(University of Missouri--Columbia, 2007)
Tomato plants (Lycopersicon esculentum Mill.) were grown to: 1) evaluate their early season yield characteristics when grown using different mulch types with and without row cover; and 2) evaluate yield potential among ...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg deposition or larval development...
The cost of milk production
(University of Missouri--Columbia, 1917)
This condition of milk prices has lead to considerable unrest in the dairy industry. State and federal experts have studied the problem, and extension and country agricultural workers, city chambers of commerce, special committes appointed...
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...
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)
. The research included fourexperiments with various temperature, hydroperiod, and nitrogen treatments to simulate climate and land use change projections. In the first study,atemperature-controlled growth chamber experiment was used to evaluate treatment effects...
A study of the property rights constraints in US agricultural cooperatives : theory and evidence
(University of Missouri--Columbia, 1998)
This research addresses the issue of efficient user-owned and controlled organizational design. Using agricultural cooperatives as an example set of user-owned and controlled institutional arrangements, the economic issue examined is the degree...
The influence of body mass and body composition on bone functional adaptation
(University of Missouri--Columbia, 2023)
The proposed dissertation follows a three article format. The articles are distinct, but each pertains to the same subject of research. The first article applies structural equation modeling to factors influencing bone functional morphology...
Understanding students' technology appropriation and learning perceptions in online learning environments
(University of Missouri--Columbia, 2005)
Distance education has the unique characteristic of using technologies as the primary means of delivery of instruction and interaction. The present study contributes to research dedicated to explaining or predicting phenomena related to distance...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
. This dissertation includes results from four studies conducted at the MU Greenley Research Center, Grace Greeley farm, and Ross Jones farm. Long-term, no-till research evaluated the influence of a wheat (Triticum aestivum L.), radish (Raphanus raphanistrum subsp...
Influence of entomopathogenic fungi from forest and urban habitats on founding pairs of reticulitermes flavipes (rhinotermitidae)
(University of Missouri--Columbia, 2015)
termite colonies survive fungal invasions. This research focused on founding pairs of primary reproductives when colonies are smallest and there are only two termites. Because most termite colonies invading newer homes in Missouri are started...
Cover crop effects on soil moisture dynamics & thermal properties
(University of Missouri--Columbia, 2021)
properties of a corn (Zea mays L.) cropping system. The study was conducted at the Elsberry Plant Material Center - USDA, Missouri, USA, with 1) no-till cover crop (NC), 2) conventional till no cover crop (CN), and 3) no-till no cover crop (NN) treatments. A...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
Body size and shape in insular environments and applications of the island rule in biological anthropology
(University of Missouri--Columbia, 2021)
The discovery of small-bodied hominin fossils in 2004 on the island of Flores, Indonesia, unearthed a large debate within biological anthropology. This debate has exemplified that there are questions and research areas that biological...
