(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) ...
Capturing the strategic pivot: Identifying the performance outcomes of new venture pivots
(2020)
to the methodological challenges that arise when approaching the subject, which include the difficulty of identifying when a pivot has taken place (in real-time, and for a sufficiently large number of ventures that researchers can have confidence in their results...
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. ...
Assessment of Statistical Methods Applied to Geochemical Data for Paleoenvironmental Interpretation: A Case Study from the Al-Azraq Basin, Jordan
(2021)
This study investigates the appropriateness of statistical methods frequently applied to inorganic geochemistry data for indicating past environments. The data examined are two large geochemical data sets of cored lacustrine ...
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 ...
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 ...
First Principles Method for Complex Cement Structure and High Entropy Alloys
(2021)
The ultimate objective of this dissertation contains two different areas of materials – secondary of Portland cement structure and high entropy alloys (HEAs). Similar concept of the computational method was applied to ...
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...
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 ...
Human Development As the Expansion of Work Capability: An Examination of Vietnam
(2020)
This dissertation aims to enhance the application of Amartya Sen’s Capability Approach by including work capability in the current assessment of human development. Development theorists have long overlooked the role of ...
Second chance competitive autoencoders for understanding textual data
(2021)
Every day, an enormous amount of text data is produced. Sources of text data include news, social media, emails, text messages, medical reports, scientific publications, and fiction. To keep track of this data, there are ...
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 ...
Multi-hazard resilience assessment of river-crossing bridges
(2021)
Bridge structures are required to possess high reliability and robustness against the concurrent effect of extreme loads and environmental attacks. To achieve such interrelated goals, it is necessary to assess the system ...
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 ...
