Eric Overmyer\u27s on the Verge a Production Focusing on Feminine Values
Get PDFEric Overmyer\u27s play On the Verge focuses on three women who leave their world in the year 1888 and enter Terra Incognita, a fanciful world that propels then into the future until they land in the year 1955. The women in Overmyer\u27s play are three extraordinary explorer/adventurers whom, I believe, are based upon three women explorers who actually lived in the late 1800s. The thrust of my thesis focuses on identifying the values displayed by the women in the play, and their real-life counterparts, and determining whether or not these values can be identified as feminine or, if indeed, there is such a distinction when focusing on values.
Chapter I states the purpose for the thesis and includes some descriptions and qualifications for the terms feminine, masculine, womanly, manly, and value. In Chapter II, the play is looked at structurally and a brief history of the real-life Victorian women is given. Chapter III discusses the overall concept of the play and Chapter IV examines the production process. Chapter V acknowledges the actors and evaluates the success of the directional concept. The conclusions drawn are based, in part, on the material discussed in the chapters, and, in part, on external evaluation and criticism found in Appendix B. Appendix A contains a number of photos of the production and Appendix B contains outside evaluations from three sources
The Virial Equation of State of Low-Density Neutron Matter
Full text linkWe present a model-independent description of low-density neutron matter
based on the virial expansion. The virial equation of state provides a
benchmark for all nuclear equations of state at densities and temperatures
where the interparticle separation is large compared to the thermal wavelength.
We calculate the second virial coefficient directly from the nucleon-nucleon
scattering phase shifts. Our results for the pressure, energy, entropy and the
free energy correctly include the physics of the large neutron-neutron
scattering length. We find that, as in the universal regime, thermodynamic
properties of neutron matter scale over a wide range of temperatures, but with
a significantly reduced interaction coefficient compared to the unitary limit.Comment: 7 pages, 6 figures, minor revisions, to appear in Phys. Lett.
Constraining mean-field models of the nuclear matter equation of state at low densities
Full text linkAn extension of the generalized relativistic mean-field (gRMF) model with
density dependent couplings is introduced in order to describe thermodynamical
properties and the composition of dense nuclear matter for astrophysical
applications. Bound states of light nuclei and two-nucleon scattering
correlations are considered as explicit degrees of freedom in the
thermodynamical potential. They are represented by quasiparticles with
medium-dependent properties. The model describes the correct low-density limit
given by the virial equation of state (VEoS) and reproduces RMF results around
nuclear saturation density where clusters are dissolved. A comparison between
the fugacity expansions of the VEoS and the gRMF model provides consistency
relations between the quasiparticles properties, the nucleon-nucleon scattering
phase shifts and the meson-nucleon couplings of the gRMF model at zero density.
Relativistic effects are found to be important at temperatures that are typical
in astrophysical applications. Neutron matter and symmetric matter are studied
in detail.Comment: 50 pages, 21 figure
