Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

Creator:: Carlson, Erik
Abstract:: Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

Finite element modeling of reinforced concrete bridge columns with steel jackets using plastic hinge integration

Creator:: Carlton, Adam K.
Abstract:: In recent years confinement requirements for concrete columns have increased in seismic regions. Steel jackets are one way to confine reinforced concrete columns. The increased confinement provides additional strength and ductility for the columns during seismic events. For reinforced concrete columns with steel jackets, there are different section properties in...

Development of a synoptic map-pattern climatology to supplement current weather forecasting methods

Creator:: Frey, Melissa D. (Melissa Dawn)
Abstract:: Many meteorologists rely heavily on their experience of past weather events to supplement their forecasting tools, such as using past experience to help decide between conflicting numerical weather prediction models. Experiential knowledge is an important piece of forecasting, however it is highly subjective and variable from one forecaster to another....

Analysis of moving loads using force-based finite elements

Creator:: Kidarsa, Adrian
Abstract:: An analysis method for moving loads computes the internal demand history in a structural member at integration points of force-based finite elements as opposed to the end forces of a refined displacement-based finite element mesh. The force-based formulation satisfies strong equilibrium of internal section forces with the element end forces...

3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

Creator:: Scoggins, Luke A.
Abstract:: A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

Separation and detection of cellooligosaccharides on cellulose thin-layer chromatography

Creator:: Sookavatana, Narumon
Abstract:: Linear oligosacchardies of 1,4 linked β-D-glucopyranose are commonly referred to as cellodextrins (CD) or cellooligosaccharides (CO). They are of interest to those working in disciplines involving cellulose chemistry because they are often used as model substrates for cellulose itself. They are of interest to food scientists and nutritionists because they...

Analytical approach to the quantitative analysis of silicon in plants : its application to plant silica extraction

Creator:: Boone, Carmen E.
Abstract:: The literature available on the silica content of herbaceous biomass, and its relative mobility in leaching/extraction systems, includes studies that have employed several different methods for silica quantification. This makes comparison of the data difficult. The objective of this thesis research was to determine the quantitative relationships between the measured...

Structural component composition of Pacific Northwest grass-derived biomass : A survey

Creator:: Masrungson, Duangdao
Abstract:: The structural component compositions of thirty nine non-commercial Pacific Northwest grasses were analyzed in order to develop a database of the grasses that may have application in bioconversion processes. The samples were chosen based on near infrared reflectance (NIR) data that suggested this group of grasses, collectively, was representative of...

Assessing and evaluating the Self-indicating Instant Radiation Alert Dosimeter (SIRAD) for gamma and neutron response

Creator:: Stewart, H. Michael
Abstract:: The Self-indicating Instant Radiation Dosimeter (SIRAD) is credit card size, self reading, single use dosimeter produced by JP Laboratories. The SIRAD has a chemical strip that changes color based upon incident radiation. The color change is instantaneous and cumulative. The card was designed for first responders as a way for...

Classical chaotic scatting from symmetric four hill potentials

Creator:: Bauman, Jordan Michael
Abstract:: Classical chaotic scattering experiments were performed on ten different four hill potentials, unique under x-axis reflection, given by: V(x,y) = x²y²e⁻⁽ˣ² ⁺ ʸ²⁾ σᵢ where σᵢ was ±1 depending upon quadrant. Our work was based on a paper (9) that only studied the case where σᵢ =1 in all quadrants....
