Chapter 1: Munchnones and mesoionic heterocycles The reactivity, regioselectivity, and synthetic applications of munchnones (1,3-oxazolium-5-olates) is a common theme which runs through Chapters 2-5. The definition, structure, and reactivity of...
In utero exposure to maternal malnutrition is associated with increase offspring susceptibility to cardiometabolic and neuropsychiatric disease. Epigenetic mechanisms mediate, at least in part, fetal adaptations to adverse in utero environments...
In this thesis, we consider several problems relating to cyclic subgroups of the group [mathematical equation]. Each element of [mathematical equation] has a unique representative in one of the two intervals [mathematical equation] and...
Acyl-CoA:Cholesterol Acyltransferases (ACATs) are key enzymes in cellular cholesterol metabolism. ACAT converts free cholesterol to cholesterol ester, which makes it more easily storable in lipid droplets. There are two ACAT genes encoding two...
Coherent states. Quantum field theory. Nonlinear theories.
In this thesis we study the properties of time-dependent, nontopological configurations and their effect on the macroscopic properties of a system described by a nonlinear field theory. These structures seem to be ubiquitous in relativistic field...
In this thesis we look at several problems that lie in the intersection between combinatorial and multiplicative number theory. A common theme of many of these problems are estimates for and properties of the smooth numbers, those integers not...
Mutualisms may facilitate coupled population expansion or decline if changes in either partner species lead to similar changes in the other species. However, few studies have measured how both species in a mutualism respond to changes in each...
As the human population increases, it is imperative that we develop strategies to improve agricultural productivity to meet the growing demand for food, fuel and fiber. More than 2 billion people suffer from "hidden hunger" (a lack of essential...
The chemistry of indole can be reversed and redirected by the addition of powerful electron-withdrawing groups. Incorporation of a nitro group at C-2 or C-3 renders the adjacent carbon susceptible to nucleophilic attack. Nitro, cyano, and...
Measurement of the ionospheric thermal particle population bridges the two different communities of ground-based radar and space-based rocket studies, which have the common goal of characterizing heavy ion transport in the cusp/cleft region. We...
Tadpoles -- Ecology -- Atlantic States. ; Anura -- Evolution -- Atlantic States. ; Tadpoles. ; Bufonidae -- Atlantic States. ; Ranidae -- Atlantic States. ; Hylidae -- Atlantic States.
Understanding the distribution of species is a long-standing goal of ecology. Progress toward this understanding requires elucidation of how present-day patterns have been generated through history. Accomplishing this demands the study of...
Motivated by the goal of investigating the dynamics of the electroweak phase transition in the early Universe, a study of dynamical aspects of nonlinear field-theoretical systems is performed. Symmetric and asymmetric double-well potentials in the...
Metal powders -- Extrusion. Metal powders -- Microstructure. Shear flow.
The manufacture of bulk parts from metastable powder materials requires new approaches to cold consolidation. One potential technique is equal-channel angular extrusion (ECAE), a simple shear process. This thesis describes an investigation into the...
The eukaryotic cilium (also called flagellum) is a complex, microtubule-based organelle that is found on many different cell types. It produces movement by the precise activation of dyneins that are located along the length and the circumference of...
Influenza virus is a respiratory pathogen that is capable of causing considerable pulmonary pathology and respiratory dysfunction in humans. Seasonal influenza epidemics and the occasional influenza pandemic are responsible for significant...
