New acoustic emission applications in civil engineering

Creator:: Schumacher, Thomas
Abstract:: Non-destructive testing methods and applications have become of increasing interest due to the worldwide aging and deteriorating infrastructure network. In the field of Civil Engineering, bridges and bridge components as well as non-structural elements such as roadway pavements for example, are affected. In particular, the Acoustic Emission (AE) technique offers...

Development of an Accelerated Method for Assessing Decay of Wood Plastic Composites (WPC's)

Creator:: Silva Guzman, Jose Antonio
Abstract:: This study examined the decay resistance of the pine and maple components of wood plastic composites (WPC' s) of varying thicknesses exposed on several culture media to wood decay fungi under laboratory conditions. The ability of malt agar extract (MEA), potato dextrose agar (PDA), amended basal salts, sawdust (maple and...

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...

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...

Crystallin proteolysis in lens during aging and cataract formation

Creator:: Ueda, Yoji
Abstract:: The major purpose of this research was to characterize partially degraded proteins appearing in the ocular lens during aging and cataract, and to identify the responsible proteolytic activities. This research is significant, because increased protein degradation is associated with lens opacification and cataract. Determining the sites where lens proteins become...

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....
Resource Type:: Dissertation
Full Text:: the targeted alkene [(E)- or (Z)- isomer] as determined by choice of carbenoid stereochemical pairing

The influence of cognitive conflict on religious thinking in fifth and sixth grade children

Creator:: Abraham, Kitty Greene
Abstract:: The purpose of this study was to test the effectiveness of two religious education curricula in facilitating measure-able concrete-to-abstract movement in children's religious thinking. Subjects for the study were 47 fifth and sixth grade children enrolled in the Sunday School classes of four Oregon United Methodist Churches. Twenty-four children who...

Effects of selenium and glutathione peroxidase on the biosynthesis of prostaglandin E₂ and F₂α by the ram vesicular gland

Creator:: Abdelgadir, Salaheldin Eltigani
Abstract:: This study was conducted to investigate the involvement of selenium and glutathione peroxidase in prostaglandin biosynthesis by the ram vesicular gland. Vesicular glands were collected from healthy intact rams covering a wide range of selenium nutrition and were analyzed for selenium concentrations, glutathione peroxidase activities and levels of prostaglandin E₂...
