The effect of gene therapy on the pathogenesis of amyotrophic lateral sclerosis (ALS)
(University of Missouri--Columbia, 2021)
Amyotrophic lateral sclerosis (ALS) is a devastating progressive and neurodegenerative disease. In early stages of ALS, there are known pathological changes in the structure of neuromuscular junctions (NMJ); however, all ...
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 ...

[less than] 0.05) to Warner-Bratzler shear force (WBSF) values at 336 h postmortem. Metmyoglobin reducing activity at 336 h exhibited moderate, positive (P [less than] 0.05) relationships with slice shear force (SSF) and WBSF values at 48 h. L*, a...
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 ...
Emplacement styles of obsidian lavas: an integrated field and laboratory study
(University of Missouri--Columbia, 2021)
Previously accepted models of emplacement dynamics of obsidian lavas have recently been called into question by observations made during the effusive eruptions of Chaiten in 2008-2009 and Cordon Caulle in 2011-2012 in ...
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...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
Soybean (Glycine max L. Merrill) is one of the most important legume crops grown worldwide. However, without phosphorus (P) fertilization, soybean yields often are limited by phosphorus availability. Phosphorus is an ...
