Investigation of elemental defense and trophic transfer of metals using beet armyworm, Spodoptera exigua, Hübner
(2012-08-06)
Elemental defense is a phenomenon in which high concentrations of a metal in plant tissues can defend a plant from herbivores. Elemental defense is one of the hypotheses proposed to explain the evolution of metal ...
A Novel Halogenation Protocol and Non-heme Iron Hydroxylase Mimics as Catalysts for C-H Oxidation and O2 Activation
(2012-08-03)
Hydrocarbons react with molar concentrations of peracetic acid and halide salts to yield predominantly monohalogenated products under optimum conditions, with chlorination being more oxidatively efficient than bromination. ...
Three Essays on CGE Modeling, Education Economics and Energy Economics
(2012-08-03)
This dissertation consists of three essays in economics on CGE modeling, education economics and energy economics.
The first essay focuses on quantifying the economic contribution of the automotive industry to ...
Reconfiguring Cultural Literacy: Multi-Authored Cultural Literacy Narratives in a Post-Hirsch Age
(2012-08-03)
My dissertation argues that Hirsch’s definition of cultural literacy must be updated so that it focuses on the behaviors, practices, beliefs, and ideals of individuals (any individual) and how each of these areas connects ...
Time-Dependent Deformations in Precast, Prestressed Bridge Girders
(2012-08-03)
Precast, prestressed girders are used across the state of Alabama for bridge construction. There has been a desire to allow self-consolidating concrete to be used to manufacture these bridge girders. The time-dependent ...
Development and Application of Composite Material Lamination Theory for Printed Circuit Boards
(2012-08-03)
Layers incorporating carbon fiber materials have been proposed to enhance the reliability of high performance printed circuit board production configurations. The carbon fiber layers feature high stiffness and high thermal ...
Biological control studies of reniform nematode in Alabama cotton crops
(2012-08-02)
Rotylenchulus reniformis is the most important pathogen of cotton in the southeastern United States. Aldicarb, which is the most used nematicide in cotton production, will be retired from the market in 2018 by the EPA. ...
Factors Governing Tin Whisker Growth
(2012-08-02)
Tin (Sn) whiskers are electrically conductive, single crystal eruptions that can grow from surfaces where tin is deposited on a substrate surface. They present reliability problems for the electronics industry due to the ...
Microfluidic Chips for Characterization of Enzyme-catalyzed Reactions and Evaluation of Dose Responses for Drug Discovery
(2012-08-02)
In last century, the discovery of semiconductors, the invention of transistors and the creation of the integrated circuit brought a revolution in the field of computation, which marked the foundation of computers and ...
The Effective Use of and Support for Instructional Strategies to Improve Literacy in the Middle Grades
(2012-08-02)
The purpose of this quantitative study was twofold. First, the researcher identified researched-based strategies which improve reading comprehension and literacy in adolescent students. Second, the researcher determined ...
Nim on Graphs
(2012-08-02)
Winning strategies for the Game of Nim on Graphs are discussed. Graphs considered are distinguished from those previously studied in that they may have loops. Winning strategies are found for graphs that have loops and ...
Incorporating El Niño Southern Oscillation (ENSO)-Induced Climate Variability for Long-Range Hydrologic Forecasting and Stream Water Quality Protection
(2012-08-02)
El Niño Southern Oscillation (ENSO) has been found to have a strong predictable effect on streamflow in different parts of the world. Since ENSO has potential relationship to seasonal and inter-annual variability in ...
Three Essays in House Foreclosures, Quasi-Experiment Model and Irrigation
(2012-08-02)
In recent years much governmental and public attention has been focused on house foreclosures as they related to the recent recession. Housing spillovers can degrade neighborhood quality and depress property tax revenues, ...
Maximal Sets of Hamilton Cycles in Complete Multipartite Graphs
(2012-08-02)
A set of S edge-disjoint hamilton cycles in a graph G is said to be maximal if the
hamilton cycles in S form a subgraph of G such that G-E(S) has no hamilton cycle. The
set of integers m for which a graph G contains a ...
Dauphin Island Birders: An examination of specialization, place attachment, satisfaction, and amenity migration
(2012-08-02)
Dauphin Island is a small barrier island off the coast of Alabama. The island sets in a major migratory flyway and annually hundreds of species descend upon the island during the spring and fall migrations. This has caused ...
