The politics of CO2 emissions
(University of Missouri--Columbia, 2020)
. The first study of the dissertation investigates whether democracy as a political institution performs better in reducing per capita CO2 emissions than non-democracies. Applying seven different empirical research designs, including the TSCS and multilevel...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
uptake ability and P use efficiency (PUE) of a crop critically influence its productivity. To improve soybean yields under low-P conditions, a better understanding of the mechanisms underlying P uptake and PUE is needed. The first part of this study...
Vasubandhu's consciousness trilogy: a Yogacara Buddhist process idealism
(University of Missouri--Columbia, 2008)
This work is a philosophical investigation into Vasubandhu's consciousness trilogy, comprised by the Trisvabhāva-Nirdeśa ("Instruction on the Threefold Own-State-of-Being,") and the Vijñaptimātra-Kārikas ("Verses on Consciousness...
Experimental and theoretical studies of CO2 capture from air and of crystalline, ferroelectric, non-linear optical materials
(University of Missouri--Columbia, 2022)
approaches. In Chapter 1 to 3, we focused on a Rubisco inspired CO2 capture material, which is made of tetrapeptide KDDE. In chapter 1, we investigated the thermochemistry of the small amine system with full conformational space and determined the best method...
Design, synthesis, and evaluation of radiolabeled bombesin conjugates for the diagnosis of breast cancer
(University of Missouri--Columbia, 2009)
to develop a series of [superscript 99m]Tc-(CO)[subscrip 3]-X-Y-BBN(7-14)NH2 derivatives, where X = PZ1 or DPR and Y = [Beta]Ala, GGG, GSG, Peg5, Peg8, SGS, or SSS, whose ability to detect and diagnose breast cancer was analyzed. Among these conjugates...
Multivariate analyses of polygenic risk for impulsivity and alcohol use: a study of longitudinal trajectories of binge drinking in emerging adulthood
(University of Missouri--Columbia, 2022)
multivariate genome-wide association study (GWAS) approaches to improve current models of neurogenetic liability for IPTs using a dual-systems framework (e.g., top-down lack of self-control, and bottom-up sensation seeking and urgency), and (2) apply improved...
Single cell-type metabolomics of Medicago truncatula border cells and their roles in host-microbe interactions
(University of Missouri--Columbia, 2022)
Border cells are a specialized cell type surrounding the root apical meristematic region of many plant species, with the exception of the Brassicaceae family that possess characteristically different border-like cells. Border cells are held in place...
Second class : local and elite media framing of poverty in the Appalachian opioid epidemic
(University of Missouri--Columbia, 2018)
as different from the rest of the country. These findings suggest an industry-wide class bias, as well as an elite-specific geographic bias. Such findings suggest a need for greater accessibility in the journalism field in general and grater geographic...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
material was packed to a bulk density of 1.3 Mg m[superscript -3] (81 lb ft[superscript -3]) in soil test beds subjected to a 61-mm h[superscript -1] (2.4-in hr[superscript -1]) simulated rainfall with a kinetic energy (KE) of 1.5 kJ m[superscript-2] h...

(University of Missouri--Columbia, 2020)
antibacterial capacity. Chapter 2 also describes a discovery of glansreginin A as a novel bacterial compound responsible for the antibacterial capacity of Mystry extract via a metabolomic approach coupled with bioassay-guided fractionation strategy. In Chapter 3...
Theoretical and computational modeling of RNA-ligand interactions
(University of Missouri--Columbia, 2021)
-learning-based model, the “Magnesium convolutional neural network” (MgNet) model, to predict Mg2+ binding site for a given 3D RNA structure, and show the use of the model in investigating the important coordinating RNA atoms and identifying novel Mg2+ binding motifs...
Instrumental analysis, sensory analysis and consumer acceptance of strained yogurt in frozen desserts
(University of Missouri--Columbia, 2021)
There is a surging demand from consumers for healthier products that are lower in calories but maintain their original flavor and texture. Many countries around the world have worked to develop new techniques to improve our food supply and food...
