The use of geomorphological and pedological soil characteristics to assess planar borrowing at a Mandan Indian village, North Dakota
(University of Missouri--Columbia, 2011)
The Double Ditch State Historic Site is situated in a loess landscape immediately east of the Missouri River near Bismarck, North Dakota. The site was occupied from ca AD 1450 to 1785 by Mandan Indians, Plains Villagers who exhibited a systematic...
Neutron diffraction studies on ABO₃ (A=La, Sr, B=Fe, Co, Ni, Cu, Mn, Ti) perovskite used in solid oxide fuel cell (SOFC) and double perovskite Ba₂YRu[0.85-subscript]Cu[0.15-subscript]O₆ superconductor
(University of Missouri--Columbia, 2009)
and a mixture of 5wt% YBa₂Cu₃O₇₋[delta subscript] and undoped Ba₂YRuO₆ were investigated with the aid of neutron diffraction. The 1:1 B site ordering is observed and long range antiferromagnetic ordering of the Ru sublattice with a type I magnetic...
An in depth evaluation of internal criteria for determining the number of clusters in a data set
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Clustering procedures partition data sets into groups, minimizing the distance within clusters while maximizing the distance between clusters. Clustering can be a powerful tool...
Flow and heat transfer properties of Mono Craters rhyolites : effects of temperature, water content, and crystallinity
(University of Missouri--Columbia, 2008)
and concentric cylinder methods to obtain viscosity measurements between 5 x 103̂ to 8 x 101̂2 Pas, from superliquidus conditions to the glass transition; the laser flash (LFA) method to measure thermal diffusivity of samples between room and subliquidus...
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 ...
Mathematical problems from cryobiology
(University of Missouri--Columbia, 2009)
in the 2- solute case. After defining optimal controls, the question arises whether the predicted continuous optimal control of the extracellular environment affects the hypotheses of the ODE model, namely, perfect stirring inside and outside of the cell...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
the following research questions: (1) How does the rheology of active flows evolve during emplacement; and (2) How can we use flow morphology to infer the rheology of inactive flows? ... At Piton de La Fournaise (La R�union, FR DOM), I addressed the longstanding...
A shellabration of early life : exploring the taphonomy, diversity, and distribution of small shelly fossils surrounding archaeocyathid reef systems in the Harkless System, Death Valley, NV
(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....
Watershed-level Analysis of Urban Raingarden Performance
(2013)
Urban flooding became to be a big issue for many cities in the world due to the urbanization. Best Management Practices (BMP) are considered to be an economically friendly solution for the urban storm water problem.
The ...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
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 ...
An evaluation of pre- and post-timber harvest water quality in low-order streams in the Missouri Ozarks
(University of Missouri--Columbia, 2009)
Missouri Department of Conservation's (MDC) best management practices (BMPs) for Regenerative Oak Clear Cutting (ROCC) practice was evaluated on effectiveness to preserve downstream water quality. Fifteen sites, located on MDC lands in Shannon...

Alkene-oxo and alkene-alkene coupling on Pt(II)
(University of Missouri--Columbia, 2005)
Tetranuclear Pt(II) oxo-complex [(COD)4Pt4([mu]3-O)2Cl2](BF4)2 (1) (COD = 1,5- cyclooctadiene) was found to readily react with a variety of alkenes (ethylene, norbornene, propylene and cyclopentene). The most significant discovery resulted from...
