The role of sigma factors in production of cyanobacterial natural products: Escherichia coli as a heterologous expression host

Creator:: Wells, Kaitlyn N.
Abstract:: Cyanobacteria represent an underexploited source of bioactive natural products of interest to the pharmaceutical industry. Lack of development of these compounds as drug leads is due mainly to myriad practical problems with the producing strains including long doubling times, genetic intractability, and low compound yields. Previous attempts at heterologous expression...

Tsunami-induced Soil Instability

Creator:: Fischer, Rachael Marie
Abstract:: Recent tsunami field surveys from the 2011 Great East Japan Earthquake and Tsunami have recorded numerous examples of tsunami-induced soil instability: significant scour around foundations, foundation failure of piles, and other damage caused by liquefaction. From the observations of soil instability leading to the failure of critical coastal structures, it...

Scaling analysis for the pebble bed of the very high temperature gas-cooled reactor thermal hydraulic test facility

Creator:: Nelson, Benjamin L.
Abstract:: The Very High Temperature Reactor (VHTR) has two possible core configurations, a hexagonal prismatic and a pebble bed. It is essential that an experimental facility be built for the validation of computer codes for the safe operation of the VHTR. The scaling of the prismatic core configuration has been analyzed...

Detection, biosynthesis, and structural investigations of naturally occurring alkynes and other microbial metabolites

Creator:: Back, Daniel C.
Abstract:: Natural products have long been an important source of resources for humans. Many of these compounds possess unique chemical structures and potent biological properties. By targeting natural products with specific chemical properties, we can gain a better understanding of the roles these compounds play in the environment and their interactions...

Aiding Plants and Humans by Targeting Virulence Strategies: Investigation of key protein residues involved in toxoflavin production

Creator:: Justen, Savannah F.
Abstract:: Toxoflavin, a toxic secondary metabolite produced by a variety of bacteria, has been implicated as a causative agent in food poisoning and a virulence factor in phytopathogenic bacteria. This toxin is produced by the tox operon in Burkholderia glumae, in which the encoded protein, ToxD, was previously characterized as essential...

The psychological affect of modern and traditional schools on students' self-concepts, self-adjustment and social adjustment

Creator:: Ross, Dorian Mordecai Roseman
Abstract:: Purpose of the Study The purpose of this study was to investigate the relationships between modern and traditional schools and children's self-concepts. In order to do this, it was necessary to describe and define the phenomenon "self-concept" as used in education and to describe what the author meant by modern...

Selective inhibition of ion absorption by uranyl

Creator:: Mason, Benjamin J.
Abstract:: The research presented in this thesis evaluated the effects of uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due to the biological importance of Na and K, these two ions were studied in the greatest detail. The results of this research showed that, at UO₂⁺⁺ concentrations...

Adjacent structure response sensitivity to seismic events using the direct differentiation method

Creator:: White, William S.
Abstract:: The response of adjacent structural systems to earthquake motions is investigated using the finite element framework OpenSees. Results of sensitivity analyses demonstrate that structural response quantities can increase in either or both of the adjacent structures for specific configurations. The structural models used include steel moment-resisting frames and rigid shear...

Pore Water Pressure Response in Soil During Tsunami Loading : Numerical Formulation and Experimentation

Creator:: Abdollahi, Abbas
Abstract:: Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Tsunami run-up causes the...
