Student Interpretations of Phylogenetic Trees in an Introductory Biology Course
(North Dakota State University, 2013)
Phylogenetic trees are a common visual representation in biology, and the most important visual representation used in evolutionary biology. Thus, phylogenetic trees have also become an important component of biology ...
Online Student Resource Use and the Effect on Student Course Performance
(North Dakota State University, 2013)
The purpose of this study was to identify potential factors of student resource use that could indicate student success in an online course. This would allow instructors to look for in patterns of use to identify students ...
Synthesis, Characterization, and Application of Low and Reduced Band Gap Thieno[3,4-b]pyrazine-based Materials
(North Dakota State University, 2013)
Conjugated polymers are a class of materials receiving significant interest due to their unique combination of optical and electronic properties found in inorganics with the flexibility and processability of traditional ...
Developing Platform Chemicals from Renewable Resources
(North Dakota State University, 2013)
The Department of Energy has listed 5-hydroxymethylfurfural (HMF) and 2,5-furandicarboxylic acid (FDCA) as two of the twelve building blocks derived from cellulosic biomass. HMF can serve as a renewable platform for the ...
Synthesis, Photophysics, and Nonlinear Absorption of Platinum (II) and Iridium (III) Complexes
(North Dakota State University, 2013)
Square planar d8 platinum(II) complexes and octahedral d6 iridium(III) complexes were synthesized. Their photophysics were studied in detail. Structure-property relationship was studied by varying the substitution on the ...
Identifying Causes of Dissolved Oxygen Depletion and Determination of Sediment Oxygen Demand in the Souris River
(North Dakota State University, 2013)
The Upper Souris River was placed on the Environmental Protection Agencies (EPA) impaired waters list for low dissolved oxygen (DO). A Total Maximum Daily Load (TMDL) study was conducted to determine possible causes of DO ...
An Anisotropic Damage Mechanics Model for Concrete with Applications for Fatigue Loading and Freeze-Thaw Effects
(North Dakota State University, 2013)
It is well known that the formation and propagation of microcracks within concrete is anisotropic in nature, and has a degrading effect on its mechanical performance. In this thesis an anisotropic damage mechanics model ...
Multiscale Modeling of Electromagnetic Radiation Transport
(North Dakota State University, 2013)
The transport of electromagnetic radiation is a critical factor in determining many of the advanced features of novel materials, composites, and coatings systems. The radiation interaction with a material's surface, as ...
Novel Conducting Polymer Containing Composite Coatings for the Corrosion Protection of Metal Alloys
(North Dakota State University, 2013)
Corrosion is a persistent problem faced by manmade structures made up of metal alloys. Aluminum 2024-T3 is high strength, light weight alloy used in aerospace applications. It suffers from the problem of corrosion due to ...
"Giving Rope and Pulling It Back" : Types and Patterns of Strategies Used by Parents to Prevent Adolescent Substance (Ab)use
(North Dakota State University, 2013)
This study contributes to the INC theory by adding the stage of prevention to the parent-child relationships' timeline. Ten parents (six mothers and four fathers) were interviewed, and a memory enhancing timeline calendar ...
