(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...
Disentangling alcohol-specific alcohol use disorder criteria from externalizing psychopathology using an empirically driven approach
(University of Missouri--Columbia, 2020)
Within current mental disorder classification systems, alcohol use disorder (AUD) and psychopathology, more broadly, are conceptualized as distinct categorical disorders. Recent classification research has focused on ...
Classification of rock glaciers in southern Colorado based on ice content using radar interferometry and thermal remote sensing
(University of Missouri--Columbia, 2020)
Remote sensing provides a means of assessing potential water resources stored in alpine ground ice; this study focuses on rock glaciers, in particular. A rock glacier is a landform composed of block of loose debris (talus) ...
Reverse knowledge absorptive capacity of MNE-HQ (RKAC): conceptualization, theoretical framework, and empirical testing
(University of Missouri--Columbia, 2021)
Despite the increasing importance of reverse knowledge for innovation and competitive advantage of multinational enterprises (MNEs), the issue of how to make reverse knowledge transfer (RKT) more effective is under-explored. ...
The ecology of organizational forms in local and regional food systems: exploring the scaling-up challenge via a species concept
(University of Missouri--Columbia, 2020)
Over the past 30 years, Western nations have developed alternative systems for exchanging agrofood products which incorporate social values into the transactional environment. These systems are comprised of many different ...
Taxonomy, taphonomy, and ecology of Silurian (late Telychian) conulariids from the Waukesha Lagerstatte, Wisconsin
(University of Missouri--Columbia, 2021)
) borrowed from the University of Wisconsin Geology Museum, Madison, USA were examined using a combination of light microscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy (SEM-EDS), to assist in the classification of these taxa...
Conservation genetics of conflict in the Asian elephant, Elephas maximus
(University of Missouri--Columbia, 2021)
The Asian elephant (Elephas maximus) is an endangered species whose distribution spans 13 countries in south, southeast, and insular Asia. The primary threats to the survival of this species include direct conflict, primarily ...
Investigations of Mississippi valley-type mineralizing fluids via analytical geochemistry, numerical modeling, and experimental geochemistry
(University of Missouri--Columbia, 2021)
Mississippi Valley-type (MVT) deposits represent enrichments of base metals and other elements up to 1000's of times greater than their average concentrations in the Earth's crust. These enrichments most commonly consist ...
Detecting and explaining differential item functioning on the social, academic, and emotional behavior risk screener
(University of Missouri--Columbia, 2020)
Universal screening of social-emotional and behavioral (SEB) risk with teacher completed brief behavioral rating scales (BBRS) is one of the primary methods for identifying SEB risk in students. These measures should function similarly across races...
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)
Equilibrium is a key theme in chemistry education. Starting in high school and continuing in freshman general chemistry courses, STEM students have to learn the foundations of equilibria. What is the key concept of an ...
Coupling, membrane conductance, and ion channel mRNA profiles in the establishment and maintenance of network activity in the crustacean cardiac ganglion
(University of Missouri--Columbia, 2021)
for unambiguous identification of cells based on anatomy or neuronal projections. We use this to evaluate the efficacy of cluster estimation procedures, clustering methods, and classification algorithms to determine the number of cell types present, group like...
Messaging universal vote by mail : an exploration of the factors that influence message processing for niche policy topics
(University of Missouri--Columbia, 2020)
According to the federal government, the current model of voting in the United States has changed little since the country's founding even as voting has moved from wooden ballot boxes to electronic voting machines and ...
An applied economic analysis of the demand for pork primal cuts
(University of Missouri--Columbia, 2021)
This study estimates domestic disappearance equations for the six main pork primal cuts (belly, butt, ham, loin, picnic, and rib) to determine the own-price, cross-price, and income elasticities for each cut. These equations ...
Phytoplankton response to water quality threats in Midwest reservoirs
(University of Missouri--Columbia, 2021)
Harmful cyanobacterial blooms and invasive species threaten water quality. These threats are expected to worsen in the future, emphasizing the need for creative management solutions and a thorough understanding of their ...
Multi-objective network optimization: models, methods, and applications
