Homospermidine, spermidine, and putrescine : the biosynthesis and metabolism of polyamines in Rhizobium meliloti

Creator:: Tower, Paula Allene
Abstract:: Rhizobium, in symbiotic association with leguminous plants, is able to fix atmospheric nitrogen after first forming root nodules. Since polyamines are associated with and found in high concentration in rapidly growing cells and are thought to be important for optimal cell growth, it is possible that these polycations are involved...

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...

Of Planes and Plumblines: Map Projections and Differential Leveling in a GNSS-based 3D Geodetic Framework

Creator:: Dennis, Michael L.
Abstract:: Modern geospatial data are frequently represented in some type of three-dimensional (3D) coordinate system, for example geodetic latitude, longitude, and ellipsoid height (φ, λ, h) derived from Global Navigation Satellite Systems (GNSS). But for engineering and surveying work, φ, λ, h coordinates are usually converted to a topocentric system consisting...

Manufacturing Process Design and Electrically-Assisted Embossing of a Microchannel Solar Receiver

Creator:: McNeff, Patrick S.
Abstract:: Manufacturing process design (MPD) represents a design-oriented approach to manufacturing engineering. In this dissertation, Haynes 230 (H230), a solid solution-strengthened Ni-based superalloy, was chosen to meet the material requirements of a microchannel solar receiver (MSR) needed to increase the efficiency and reduce the cost of solar thermal power generation. An...

Use of a geographical information system to modify pheromone trap-based predictions of Helicoverpa zea (Boddie) damage

Creator:: Drapek, Raymond James
Abstract:: The GRASS (V. 4.0) geographical information system (GIS) was used to test the hypothesis that pheromone trap based predictions of Helicoverpa zea (Boddie) damage in processed sweet corn could be improved by considering spatial patterns of corn plantings and wind blocking features around the trap. Wind blocking features include: tree...

Identification of structural parameters and hydrodynamic effects for forced and free vibration

Creator:: Kruchoski, Brian L. (Brian Louis)
Abstract:: Statistically-based estimation techniques are presented in this study. These techniques incorporate structural test data to improve finite element models used for dynamic analysis. Methods are developed to identify optimum values of the parameters of finite element models describing structures. The parameters which may be identified are : element area, mass...

Forging new paths : life course transitions for American women and their families

Creator:: Schmiege, Cynthia J.
Abstract:: Families of remarriage constitute a growing number of American families. The spiraling divorce rate of the 1970s was accompanied by a concomitant increase in the number of remarriages. Forty percent of American families today contain at least one spouse that has been previously married, thus studying relationships within families of...

Time-based noise-shaping techniques for time-to-digital and analog-to-digital converters

Creator:: Young, Brian LeRoy
Abstract:: In this dissertation, time-based signal processing techniques and their applications in oversampling and noise-shaping data converters are examined. These techniques demonstrate the ability to shift the burden of high performance analog circuits from the compressed voltage-domain to the augmented time-domain. First, the potential of high order noise-shaping and phase-domain feedback...

Development and experimental validation of a discrete particle simulation for fluidized beds with external and inter-particle forces

Creator:: Reed, Brian Patrick
Abstract:: Traditional modeling of fluidized bed operations has focused on the development of models and correlations for specific systems or narrow areas of application. With recent advances in computing power, new methods of modeling fluidization are possible. One such approach is the Computational Fluid Dynamic Discrete Particle Method (CFD-DPM), which treats...

A reinterpretation, and new demonstrations of, the Borel Normal Number Theorem

Creator:: Rockwell, Daniel Luke
Abstract:: The notion of a normal number and the Normal Number Theorem date back over 100 years. Émile Borel first stated his Normal Number Theorem in 1909. Despite their seemingly basic nature, normal numbers are still engaging many mathematicians to this day. In this paper, we provide a reinterpretation of the...
