The development and characterization of miniature spectrometers for measuring the redox status of environmental samples

Creator:: Cantrell, Kevin
Abstract:: A spectrometer, here denoted a Simple, Low-power, Inexpensive. Microcontroller-based or SLIM spectrometer. was developed that exploits the small size and low cost of solid-state electronic devices. This approach results in customizable spectrometers that are considerably less expensive and smaller than traditional instrumentation. The performance of the SLIM spectrometer was evaluated...

Chemical composition studies of Oregon and Washington coastal basalts

Creator:: Hill, Dale Wayne
Abstract:: Basalts of both Eocene and Miocene age from several groups along the Oregon and Washington coasts have been analyzed for some major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed in these samples are used for comparisons within the groups studied...

Purification of 2,5-dihydroxyacetanilide epoxidase and mechanism of hydroquinone epoxidases

Creator:: Kirchmeier, Marc J.
Abstract:: 2,5-dihydroxyacetanilide epoxidase from Streptomyces LL-C10037 (DHAE I) catalyzes the epoxidation of hydroquinone 4, to form epoxyquinone 7. DHAE I has been purified to homogeneity, with an overall purification factor greater than 23,000. N-terminal and internal amino acid sequences have been obtained from the purified enzyme so that the epoxidase gene...

Variations in trace element abundances in small fragments from a single terrestrial basaltic flow : applications to 59 Apollo-17 mare basaltic fragments

Creator:: Rivera, Maria Rita Dacanay
Abstract:: Eleven hand specimen whole rock (WR) samples (25-200 g each) and 33 fragments (0.5-0.8 g each) from a single basaltic flow at Picture Gorge, Oregon were analyzed via instrumental neutron activation analysis (INAA) for 12 elements (Na, Fe, Cr, Sc, Co, La, Sm, Eu, Yb, Lu, Hf and Ta). Standard...

A spectrophone study of vibrational relaxation in methane

Creator:: Breshears, Wilbert Dale
Abstract:: The spectrophone method for the study of vibrational relaxation has been claimed to possess a distinct advantage over the more commonly used ultrasonic techniques in that it permits the relaxation of the various infrared-active vibrational modes in a polyatomic molecule to be studied separately. A discussion of the rate equations...

Structure-property Relationships of Transition Metal Oxides Containing Precious Metals

Creator:: Hapuraja Pathirannehelage, Vidhara H. P.
Abstract:: This dissertation presents a study of structure-property relationships within 3d/4d metal oxides containing precious metals through detailed structure refinements using high-resolution neutron and X-ray diffraction data along with exploration of the resultant properties. Oxides of 4d or 5d transition metals tend to show new topological phases due to significant spin-orbit...

Effects of small molecule ligands on the conformational dynamics of the Farnesoid X Receptor ligand binding domain (FXR-LBD)

Creator:: Yang, Liping
Abstract:: The Farnesoid X Receptor (FXR) is a member of the nuclear receptor superfamily of transcription factors that plays a key role in the regulation of bile acids, lipid and glucose metabolisms. The regulative function of FXR is governed by conformational changes of the ligand binding domain (LBD) upon ligand binding....
