Helical tool geometry in stability predictions and dynamic modeling of milling
(University of Missouri--Columbia, 2007)
in an effort to validate TFEA results for machining Ti6Al4V using a helical tool....
Synthesis and characterization of novel phosphinimine ligand systems for potential applications in radiopharmaceuticals
(University of Missouri--Columbia, 2007)
Multidentate phosphinimine ligands, C₂₅H₄₉N₂P₂Si₂,(2) C₃₄H₃₈N₂P₂Si₂(3), and C₅₀H₆₆N₃P₃Si₃(4), were synthesized in near quantitative yields by Staudinger reaction using appropriate phosphines. Coordination chemistry of 2 and 3 with Re was performed...
Sharp estimates of the transmission boundary value problem for dirac operators on non-smooth domains
(University of Missouri--Columbia, 2006)
This thesis derives the sharp estimates for the transmission boundary value problems (TBVP) for Dirac operators in Lipschitz domains in the three dimensional setting. Most of the transmission problems considered in the ...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
feed rate was varied between 6.4 g/min and 19.7 g/min, the ethanol feed rate was varied between 0.17 g/min and 2.2 g/min, and the pressure was fixed at 24.2 MPa. All ethanol fed was converted into gaseous products: hydrogen, carbon dioxide, methane...
Modeling of molecular and particulate transport in dry spent nuclear fuel canisters
(University of Missouri--Columbia, 2007)
There are two important phenomena associated with the depressurization of a dry spent nuclear fuel canister after the formation of a through-wall pinhole breach. The first phenomenon is the release from the canister of any ...
Functional characterization of two putative mobile elements of the 'Mycoplasma mycoides cluster'
(University of Missouri--Columbia, 2008)
-living organisms. This dissertation focuses on the functional characteristics of two recently characterized putative mobile elements of the ruminant-infecting Mycoplasma mycoides cluster: a 3.4-kb cryptic plasmid, pMyBK1, of Mycoplasma yeatsii, and an approximately...
Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)
Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ...
Adaptive array signal processing using the concentric ring array and the spherical array
(University of Missouri--Columbia, 2009)
This thesis introduces new methods for partial adaptive beamforming using concentric ring and spherical arrays for acoustic signals on a partially known interference environment. We propose novel methods to choose intra-ring ...
Anion and solvent influences on the self-assembly of copper(I) coordination solids
(University of Missouri--Columbia, 2005)
and the reaction conditions involved will be discussed. This presentation will be divided into four major sections. The first section covers an in-depth look at those structural variances found among the copper(I) coordination solids synthesized using 4,4...
Oxidative DNA damage by 1-hydroxyphenazine, virulence factor of Pseudomonas aeruginosa : towards a molecular understanding of the bacterial virulence factor 1-hydroxyphenazine
(University of Missouri--Columbia, 2008)
1-Hydroxyphenazine is a secondary metabolite and virulence factor of Pseudomonas aeruginosa. This organism colonizes the airways of the patients of cystic fibrosis and causes progressive destruction of the airways. It is ...
The Spoon Toe Site (11MG179): Middle Woodland gardening in the lower Illinois River Valley
(University of Missouri--Columbia, 2005)
This thesis is an examination of archaeobotanical remains from the Spoon Toe site, a Middle Woodland Massey phase site located in the uplands above the Lower Illinois River valley in Morgan County in western Illinois. The ...
Effect of a single AGE modification on the structure and chaperone activity of human alphaB-Crystallin
(American Chemical Society, 2007)
During aging, human lens proteins undergo several post-translational modifications, one of which is glycation. This process leads to the formation of advanced glycation end products (AGEs) which accumulate with time possibly ...
Evaluating alginate and organic acids for restructured carp intended for zoo animal and human diets
(University of Missouri--Columbia, 2008)
were analyzed for texture, pH and water holding capacity by using standard methods. Statistical results showed that the texture of all the treatments are significantly different (P [less than] 0.05) from the control. Treatment T3 had significantly low pH...
A fast, 3 MV Marx generator for megavolt oil switch testing and integrated Abramyan network design
(University of Missouri--Columbia, 2005)
The University of Missouri-Columbia has a new test facility online to study oil breakdown of enhanced and uniform gaps. The 3 megavolt Marx generator is operational with switch configurations tested including large electrode ...
Drug resistance in D. discoideum: isolation of 4-nitroquinoline 1-oxide resistant mutants
(University of Missouri--Columbia, 2005)
The drug 4-nitroquinoline 1-oxide (4NQO) displays both carcinogenic and antitumor effects, a well known characteristic of many chemotherapeutic drugs. In addition 4NQO shares a similar operating mechanism with the commonly used chemotherapeutic drug...
Land cover classification from satellite imagery, and its applications in cellular network planning
