Measurement of radionuclides in biological tissues from occupationally exposed individuals
(University of Missouri--Columbia, 2022)
suggesting that hair and nail are a long-term excretion pathway for these actinides. The 240Pu/239Pu isotopic ratios indicated an exposure to weapons-grade plutonium. In several cases measured 235U/238U atom ratios were not consistent with natural uranium...
Part I: Synthesis of functionalized bile acids towards the construction of steroidal macrocycles. Part II: Evaluation and expansion of a modular card game for teaching organic chemistry
(2019)
macrocycles. These have been coupled together via oxygen-free Sonogashira reaction conditions to form large barrel-like steroidal architectures. These structures were investigated by 1H NMR, 13C NMR spectroscopy, and HR-MS, and MALDI-TOF spectroscopy. In part...
Structural, biochemical, and inhibition studies of proline biosynthetic enzymes

Cover crop effects on corn plant water uptake and soil health
(University of Missouri--Columbia, 2019)
, are used for soil quality improvement. However, the effects of CC on water use of the following corn (Zea mays L.) crop is not yet studied. Also, CC effects on soil water availability is yet inconclusive. Although CC are believed to play a major role...
Global bifurcation and stability of solitary waves in two-layer water
(University of Missouri--Columbia, 2022)
The present work concerns two mathematical problems on wave in a stratified body of water governed by the incompressible Euler equations. In the first part, we present a large-amplitude existence theory for two-dimensional solitary waves by means...
Developing and Utilizing Multivariate Stochastic Wireless Channel Models

Developing accurate channel models is paramount in designing efficient mobile communication systems. The focus of this dissertation is to understand the small-scale
fading characteristics, develop mathematical tools that ...
The Role of Experiential Avoidance in the Relationship Between Emotional Pain and Yearning in Sudden and Unexpected Bereavement
(University of Missouri -- Kansas City, 2019)
Individuals who have experienced a sudden or unexpected loss of a close family
member or friend are at heightened risk for developing psychiatric morbidity, including
prolonged grief disorder (PGD; i.e., pathological ...
Arsenic-72, 77 as a matched pair radiopharmaceutical for imaging and radiotherapy
(University of Missouri--Columbia, 2018)
). Radioimmunoimaging and therapy commonly use antibodies (or antibody fragments) as targeting biomolecules, and may take a few days to accumulate in tumor cells. Thus they require radionuclides with longer half-lives. Arsenic-72 ([beta]+, 26 hour half-life) and 77As...
A meta-analytic review of the relation between impulsivity-related traits and family history of alcoholism
(University of Missouri--Columbia, 2018)
was much larger among those with more than one alcoholic family member (d = -.66 [95% CI: -1.10, -.22], k = 3). A small-to-moderate effect size was found for sensation seeking (d = .30 [95% CI: .21, .40], k = 29) and was moderated by age (Z = 3.09, p = .002...
Merging technology development of trapped ion mobility spectrometry quadrupole time-of-flight mass spectrometry with biological investigation of Medicago truncatularoot exudates
(University of Missouri--Columbia, 2020)

Structural studies of flavoprotein inhibitors and inactivators
(University of Missouri--Columbia, 2020)
by T2C was slow, it led us to the discovery of two related inactivators of PRODH: tetrahydrothiophene-2-carboxylate (C2C) and 1,3-dithiolane-2-carboxylate (D2C), presented in Chapter 2. The inactivators D2C and C2C differed from T2C by only one atom...
