(University of Missouri--Columbia, 2023)
framework builders and their small shelly fossil (SSF) inhabitants. This study focuses on lower Cambrian (Series 2, Stage 4) SSF assemblages from the Harkless Formation in southern Esmeralda County, Nevada, as a comprehensive systematic and quantitative...
Bayesian cusp regression and linear mixed model
(University of Missouri--Columbia, 2022)
the Bayes factors. The performance of the options are examined by numerical studies. Finally, we prove the consistency of Bayes Factors of our proposed priors in 2-way ANOVA model....
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...
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...
Corridors and deer-vehicle collisions along Missouri interstate highways
(University of Missouri--Columbia, 2022)
A total of 3,639 deer-vehicle collisions (DVCs) were reported on Missouri roadways in 2020, resulting in 348 injuries and 5 deaths. Missouri is ranked 15th nationwide for this type of accident. Of the DVCs, 490 occurred along 1,200 miles of urban...
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
(2021)
By constraining the conditions in which billowed structures form, the conditions of explosive vs. non-explosive magma-water interaction can be further revealed, improving our understanding of how magma propagates and ...
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...
Investigation of CO2 capture systems, Lewis acid-base pairs, and oscillating reactions with electronic structure theory and kinetics-based approaches
(University of Missouri--Columbia, 2020)
published in the literature. A careful read of the literature clearly showed early on that experimental and theoretical reports on F3B[arrow]PH3 are entirely inconsistent. It took years to explain what was actually measured, namely the compound F2B-PH2...
Development and evaluation of a site stormwater analysis calculator intended for the State of Missouri utilzing regional best management practices
(University of Missouri--Columbia, 2023)
The Site Stormwater with Best Management Practices (BMPs) Analysis Calculator was created to be utilized in the State of Missouri for developing or re- developing property. Simplistic and conservative stormwater evaluations utilizing regional...
First Principles Method for Complex Cement Structure and High Entropy Alloys
(2021)
difference between them even though thaumasite has the Si tetrahedron as the backbone unit in contrast to ettringite with Al-columns and no Si atoms. Moreover, thaumasite has strong C–O bonds that are absent in ettringite, and ettringite has far more water...
Entrained Air-Void System For Durable Highway Concrete
(2020)
of the air void system. These changes include: 1- Procedural modifications including longer curing times to better encompass requirements for higher SCM mixtures and the introduction of a drying period to better simulate actual field exposure conditions, 2...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
was performed at temperatures between 125 and 200 degrees C, 10 MPa pressure, and aqueous Zn concentrations from about 10 to 1000 ppm for periods of time ranging from 10 to 80 days. The D values calculated from these experiments have applications in hydrothermal...
Investigation of glycerol-based sol-gel synthesis of Li1Ni0.8Co0.1Mn0.1O2 layered transition metal oxide cathodes for lithium-ion batteries
(University of Missouri--Columbia, 2023)
of the material. Li1Ni0.8Co0.1Mn0.1O2 (NCM811) is of great interest to current research because it might be able to achieve working capacities in the range of 220-240 mAh/g, with initial discharge capacities possibly as high as 270 mAh/g. The sol-gel process...
Intense Shallow Magma Sediment Mingling within Dikes at Guffey Butte Maar, Idaho
