The analysis explores how these worldviews are allegorically implied within ancient literature and mythology. The project studies worldviews of ancient societies in regards to their socioeconomic and cultural evolution. I thank you for taking the time to study the academic discourse available here, and I know our student presenters are grateful for your attention and time. Our bright students, making and sharing new discoveries, are a source of hope. In spite of the grave challenge we confront, I am inspired by our students’ work: novel chemical syntheses, music visualizers, fish assemblages and water quality, the history of racial uplift ideology, a comparative study of immigration and rent, a study of individual-directed acts of terror, and so much more. We encourage everyone to explore, read, and learn more about the impressive variety of projects by clicking on links to materials provided by the presenters. The schedule uses the familiar color-coded department and program structure. However, the C S mode does not vanish at the initial phase transformation pressure rather, the ratios of C S K S are 0.10 and 0.04 to 0.10 for transitions of rutile → orthorhombic and of rutile → “distorted fluorite”, respectively, and are in agreement with the approach of Demarest et al.Although our symposium must be a remote affair this semester, I am happy to invite our campus community to learn about our students’ excellent scholarship. The pressure dependence of shear elastic constant C S = ( C 11 − C 12)/2 is negative in all of the nine difluorides and oxides. Velocity-density systematics in the difluorides and oxides are governed, to a large extent, by cationic radius. It is therefore not possible to predict without uncertainty the post-stishovite phases in the lower mantle. The relationship in oxides (SnO 2, TiO 2 and GeO 2) is much less systematic.
For a given phase transformation sequence found commonly in two or more difluorides, the phase transformation pressure is related inversely to the unit cell volume and thus inversely to the mean cation-anion bond length. Pressure-induced phase transformations in each of the rutile-structured difluorides (NiF 2, MgF 2, CoF 2, ZnF 2, FeF 2 and MnF 2) exhibit unique behavior however, a general trend is found in the major structural changes: rutile phase → “distorted fluorite” phase → post-“distorted fluorite” phase with volume changes of about 5–10%.
