Discrete compression web bracing design for light-frame wood trusses

Creator:

Waltz, Miles E.

Abstract:

As part of a roof framing system, light-frame wood trusses often require lateral bracing to reduce the effective length for flexural buckling of compression web members. This observational research investigates the design requirements for discrete compression web bracing intended to provide such lateral support. Four simple brace analysis methods based...

Mandelalides as Potent Mitochondrial ATP Synthase Inhibitors : From Discovery of New Analogs to Function-Oriented Synthetic Studies

Creator:

Nazari, Mohamad

Abstract:

Our quest for pharmaceutically important marine natural products led to re-isolation of known mandelalides A-D and identification of new congeners E-L from re-collected South African Lissoclinum tunicate specimens. Mandelalides A, B, and L were characterized as selective cancer cell toxins, with an unusual activity profile influenced by their glycosylation /...

Measurement of the rates of reductive dechlorination of chlorinated phenols

Creator:

Nicholson, David K.

Abstract:

Knowledge of a compound's degradation pathway is crucial to the assessment of risk at contaminated sites. Pentachlorophenol and its metabolic products can serve as model compounds to study the fate and transport of halogenated aromatic compounds in the environment. Acclimation of anaerobic sewage sludge to pentachlorophenol produced a microbial consortium...

Evaluation of different monitoring strategies for public health protection : harmful algal bloom surveillance at Devils Lake, Lincoln City, OR

Creator:

Hitchko, Kara L.

Abstract:

Cyanobacteria are photosynthetic bacteria capable of producing toxins, including complex cyclic peptides called microcystins. Hazardous cyanobacterial blooms are an emerging public health concern and are monitored throughout Oregon in various recreational and drinking water bodies. Oregon has been proactive and responsive to the problems associated with toxic cyanobacterial blooms, but...

Advanced studies on cyclic amino acids in neurological signaling and peptide antibiotics

Creator:

Blanchard, David, L.

Abstract:

L-pipecolic acid (L-PA) is the higher homolog of proline. It occurs naturally in many organisms, including primates, as an intermediate in lysine degradation. The pathway by which lysine is converted into L-pipecolic acid employs the enzyme Lpipecolate oxidase (L-PO), and appears to be tissue specific to the central nervous system...

The cohomology rings of seven dimensional primitive cohomogeneity one manifolds

Creator:

Ultman, Shari K.

Abstract:

A striking feature in the study of Riemannian manifolds of positive sectional curvature is the narrowness of the collection of known examples. In this thesis, we examine the structure of the cohomology rings of three families of compact simply connected seven dimensional Riemannian manifolds that may contain new examples of...

Broadening the scope of the modified-Julia reaction : a mild and stereoselective method for the synthesis of (Z)-configurated α,β-unsaturated lactones

Creator:

Giesbrecht, Heath Eugene

Abstract:

An intramolecular variant of the modified-Julia olefination was demonstrated by the synthesis of α,β-unsaturated lactones in a mild and (Z)-selective fashion. The lynchpin reagent (benzothiazol-2-sulfonyl) acetic acid was synthesized in a straightforward fashion in 86% overall yield from commercially available 2-mercaptobenzothiazole via conversion to ethyl (benzothiazol-2-ylthio)acetate by base mediated alkylation...

Heavy fermion effective mass in the superconducting vortex state

Creator:

Townsend, Emily A.

Abstract:

The extended-Lifshitz-Kosevitch formalism (ELK) unifies the treatment of the de Haas-van Alphen (dHvA) effect, allowing it to transcend its traditional roles of mapping Fermi surfaces and measuring effective masses. Here we exploit the capabilities of dHvA as a probe of many-body effects to examine heavy-fermion su- perconductivity. ELK successfully describes...

Quantifying the Unproductive Water Lost as Evaporation from Different Irrigation Designs by Analysis of the Soil Stable Water Isotope Compositions

Creator:

Al-Oqaili, Firas M.

Abstract:

The knowledge about the intensive agricultural irrigation is very limited, but the use of irrigation is rapidly increasing. As an outcome, the sympathetic ecosystem is accepting modern irrigation that will play an essential function in the present and future for agricultural products. My dissertation will display the modification for investigation...

Development of Methods for Stereoselective Carbon-Carbon Bond Formation

Creator:

Wu, Zhenhua

Abstract:

Three distinct methods to achieve the stereoselective synthesis of carbon-carbon bonds were investigated, encompassing: (i) the formation of axially chiral biaryl molecules by enantioselective Suzuki cross-coupling, (ii) the synthesis of α-phenylalkylboronic esters by enantioselective chain extension, and (iii) the stereospecific synthesis of alkenes by eliminative cross-coupling of enantioenriched sp³-hybridized carbenoids....
