Mixed anion compounds that form ZrCuSiAs-type crystal structures exhibit remarkable properties such as superconductivity at low temperatures,
hole conduction with optical transparency in the visible region, and exciton absorption at room temperature. In this thesis, properties of a selected group of materials out of the very large set of mixed...
This thesis presents the results of quantum-mechanical first principles calculations
of optical, electronic and mechanical properties of organic molecules and solids, which have
diverse potential applications such as photovoltaics, flexible electronics, and mechanical
catalysts with applications in force sensors and self-healing materials.
The electronic and optoelectronic properties of organic thin...

Ninety-six hour acute toxicity bioassays were employed to
determine the tolerance of juvenile coho salmon to chlorinated
stabilized kraft mill effluent (SKME). In addition the effect of
chlorinated SKME on the growth of juvenile coho salmon in six and
ten day experiments was studied.
Results of the acute toxicity tests...
This thesis describes the development of a rare earth element (REE) proxy for paleoceanographic studies of climate change. This work was done in three stages with the goal: (1) To develop a cleaning method that overcomes the problems of REE readsorption; (2) To measure pore water REEs for evaluation of...
Replication associated protein and enzyme activity levels increase as cells enter
S-phase of the cell cycle and diminish as cells leave S-phase. Accordingly, replication
associated functions decrease as myoblasts withdraw from the cell cycle to terminally
differentiate. In an effort to understand signals effecting growth associated expression
of genes, the...
Reporter gene transactivation by human p53 is inhibited in budding yeast lacking the TRR1 gene encoding thioredoxin reductase. Thioredoxin reductase specifically catalyzes the NADPH-dependent reduction of thioredoxin. Thioredoxin provides a source of electrons for disulfide reduction in various cellular processes. Reduction of disulfides within the cell can be accomplished by...
Meadowfoam (Limnanthes alba Benth.), an open-pollinated herbaceous
winter annual, is adapted to Mediterranean climates and produces
a seed oil with industrial uses. Seed yield in meadowfoam is
partially determined by the number of seeds produced per flower. The
flower is protandrous with the stigmata becoming receptive 1-3 days
after anther...
