Soil testing in Missouri : a guide for conducting soil tests in Missouri
(2022)
"Missouri Agricultural Experiment Station Bulletin 734, An Explanation of Theory and Methods of Soil Testing by E. R. Graham (1) was published in 1959. It served for years as a guide. In 1977 Extension Circular 923, Soil Testing in Missouri...
Associations between psychosis risk and emotional distress disorders with cortical surface morphometry
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Neuroimaging studies have consistently found structural cortical abnormalities in schizophrenia, especially in structural hubs. However, it is unclear what...
Validating the use of machine learning techniques in evaluating additive manufactured elastic materials
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As additive manufacturing continues to find widespread use in research and industry and the number of materials suitable for use in additive manufacturing, there is increasing...
Harmonic wavelet analysis of surface waves at complex geotechnical sites
(University of Missouri--Columbia, 2020)
The use of stress wave-based geophysical methods in geotechnical engineering has continued to grow and is now a routine component of many geotechnical site investigation programs. Surface wave methods, in particular, are ...
Late Holocene Stratigraphic History of the Gulf of Aqaba Coastal Plain, Jordan
(2020)
Construction of the lower tidal lagoon at the Ayla Oasis Development in Aqaba, Jordan provided a unique opportunity to study the 3-D architecture of coastal plain sediment of the northern Gulf of Aqaba. Previous studies ...
The Impact of Climate Variability and Land Cover Change on Groundwater Resources in The Niger River Basin
(2021)
The Niger River Basin (NRB) has experienced severe droughts and floods under a significant change of the land use and land cover (LULC) with increasing population over the years. The present study is to understand the ...
Intense Shallow Magma Sediment Mingling within Dikes at Guffey Butte Maar, Idaho
(2022)
The interactions between magma and shallow unconsolidated sediments on the way
to the surface influences the eruption behavior and products. Phreatomagmatic eruptions are
a result of the interaction of magma and water ...
Top-soil root architecture characteristics of obsolete and modern soybean cultivars and shoot and seed nutrient contents
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max Merr.) is one of the most important cash crops worldwide. It is widely used to produce oil and protein for food and animal feed. Soybean grain...
Hydrodynamic characteristics and capillary-assisted heat transfer enhancement of non-condensing/condensing two-phase flows
(University of Missouri--Columbia, 2020)
Interfacial characteristics of two-phase flows were studied through visualization experiments and numerical simulation using computational fluid dynamics (CFD) based on the volume-of-fluid (VOF)-continuum surface force (CSF) method...
Entrained Air-Void System For Durable Highway Concrete
(2020)
In the US, the most commonly used F-T test method is AASHTO T 161 “A.” The equipment for variant A of the test is relatively low cost (~$22, 000) and compact. The relatively low cost stems from the basic construction of a ...
Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
(University of Missouri--Columbia, 2022)
volumes and diameters for statistical comparison between the two different size classes of coprolite. In combination with volume renders of the segmented material, we also adopt more traditional methods such as thin-section petrography and scanning...
Northern bobwhite brood ecology and population dynamics in southwest Missouri
(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) have experienced widespread, long-term population declines. Bobwhite populations in Missouri have declined 2.7% annually between 1966 and 2015, and 3.5% annually between 2005 and 2015, for a cumulative loss...
A numerical simulation of a single shock-accelerated particle
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Particle drag models, which capture macro viscous and pressure effects, have been developed over the years for various flow regimes to enable cost effective simulations...
Using metabolic and biochemical characteristics of postmortem muscle to investigate the interconnectedness of beef color, flavor, and tenderness
(University of Missouri--Columbia, 2021)
Understanding relationships between beef palatability and quality components are crucial for continued production of high quality and consistent beef products. Myoglobin concentrations at 48 and 336 h resulted in moderate, ...
Improving ligament tissue scaffold with the use of genipin and gold nanoparticles
(University of Missouri--Columbia, 2020)
Decellularized tissue is used for a wide array of tissue injuries with tendon and ligament repair being among the most common. However, despite their frequent use there is concern over the lengthy inflammatory period and ...
Diversity and evolution of the sauropsid trigeminal sensory system
(University of Missouri--Columbia, 2022)
Understanding the evolution of sensory perception is essential in explaining organismal behavior. Organisms using environmental stimuli to navigate their environments, avoid predation, capture prey, and find a mate, have ...
Quantitative Characterization of Billowed Structures Along the Margins of Basaltic Intrusions to Determine Process and Timing of Formation: Case Studies from Big Bend National Park, Texas and 71 Gulch, Idaho
