Movement Ecology and Population Dynamics of the Endangered Hawaiian Duck (Anas wyvilliana)

Creator:: Malachowski, Christopher P.
Abstract:: Fundamental objectives in the field of conservation biology involve understanding the processes that influence small and declining populations and applying that knowledge to develop appropriate monitoring strategies and targeted management and conservation actions. Critical first steps in determining the relative role of factors that drive population declines involves estimation of...

Mahler's order functions and algebraic approximation of p-adic numbers

Creator:: Dietel, Brian Christopher
Abstract:: If P is an integer polynomial denote the degree of P by ∂(P) and let H(P) be the maximum of the absolute value of the coefficients of P. Define Λ(P)=2[superscript ∂(P)]H(P) and for a fixed prime p let C[subscript p] denote the completion of the algebraic closure of the p-adic...

Xenobiotic biotransformation in aquatic organisms

Creator:: Schlenk, Daniel K.
Abstract:: Aquatic animals are exposed to a variety of natural and anthropogenic xenobiotics. Biotransformation of xenobiotics was examined in three aquatic animals: a primitive mollusc (chiton); a shellfish which is an important human food source (oyster); and, a lower vertebrate model for toxicological studies (rainbow trout). Since digestive glands of Cryntochiton...

Helping end-user programmers find and fix performance problems in visual code

Creator:: Chambers, Chris
Abstract:: End-user programmers often struggle to create programs that run quickly and effectively, which can be a major deterrent in completing their tasks as desired. Current research has primarily focused on catching user mistakes, such as errors or misused formulas. However, end users deal with issues other than just correctness. In...

Cardiovascular disease risk in adults with mental retardation and Down syndrome

Creator:: Draheim, Christopher Charles
Abstract:: Individuals with Down syndrome (DS) have less atherosclerosis than others with and without mental retardation (MR). Why individuals with DS do not develop atherosclerosis similarly to others is not known. The insulin resistance syndrome (IRS), a common neuroendocrine disorder underlying cardiovascular disease, has not been investigated in adults with DS...

Modeling climate, vegetation, and water balance at landscape to regional scales

Creator:: Daly, Christopher
Abstract:: The general objective of this study was to develop models and datasets that would significantly advance our ability to assess the current and future effects of global change on the biosphere. The focus was in two areas: (1) preparing environmental datasets at regional to small watershed scales; and (2) developing...

Regulation of ribonucleotide reductase analyzed by simultaneous measurement of the four enzyme activities

Creator:: Hendricks, Stephen P.
Abstract:: The first committed step in DNA biosynthesis occurs by direct reduction of ribonucleotides. This reduction is catalyzed by ribonucleotide reductase (RNR), an enzyme which uses a unique radical mechanism to facilitate the transformation. All four DNA precursors are synthesized by a single enzyme. Therefore, an intricate pattern of regulation has...

The role of avian predators in an Oregon rocky intertidal community

Creator:: Marsh, Christopher P.
Abstract:: Birds affected the community structure of an Oregon rocky shore by preying upon mussels (Mytilus spp.) and limpets (Collisella spp.). The impact of such predation is potentially great, as mussels are the competitively dominant mid-intertidal space-occupiers, and limpets are important herbivores in this community. Prey selection by birds reflects differences...

Regioselective Synthesis of Substituted Phenols, Benzenes, Benzofuranones and Benzofurans and Synthesis of Homoharringtonine Analogs

Creator:: Zhang, Xiaojie
Abstract:: Substituted phenols are important substructures for pharmaceuticals, agrochemicals, natural products and biological probe molecules. The properties of phenolic molecules are substantially influenced by the substitution patterns of the phenolic ring. The chemical synthesis of phenols with various substitution patterns is an enduring challenge and multiple strategies have emerged. However, some...

Unique Structural Properties and Motifs of Metal-Oxides from Solids to Clusters

Creator:: Malmberg, Christopher E.
Abstract:: In this dissertation, the structural properties, thermodynamics and defect behavior of amorphous metal oxides and polyoxometalates are studied. Amorphous metal oxides have many applications, most notably as a semiconducting material used as the active matrix of thin film transistors. Alas, the amorphous nature of these materials makes studying them rather...
