Effective potential for nonrelativistic non-Abelian Chern-Simons matter system in constant background fields
We present the effective potential for nonrelativistic matter coupled to
non-Abelian Chern-Simons gauge fields. We perform the calculation using a
functional method in constant background fields to satisfy Gauss's law and to
simplify the computation. Both the quantum gauge and matter fields are
integrated over. The gauge fixing is achieved with an -gauge in the
limit. Divergences appearing in the matter sector are regulated via
operator regularization. We find no corrections to the Chern-Simons coupling
constant and the system experiences conformal symmetry breaking to one-loop
order except at the known value of self-duality. These results agree with
previous analysis of the non-Abelian Aharonov-Bohm scattering.Comment: 17 pages in Tex (phyzzx), UdeM-LPN-TH-94-200, CRM-219
A study of stress-free living bone and its application to space flight
Observations of animals and human subjects in weightless space flight (Skylab and COSMOS) document altered bone metabolism. Bone metabolism is affected by a number of local and systemic factors. The calcification and growth of transplanted bone is independent of local muscle, nervous, and mechanical forces; therefore, transplanted bone would provide data on the role of local vs. systematic factors. Bone metabolism in living transplanted bone, devoid of stress, was investigated as a possible tool for the investigation of countermeasures against disuse bone loss. An animal model using Sprague-Dawley rats was developed for transplantation of femur bone tissue on a nutrient vascular pedicel. The long term course of these implants was assessed through the measure of regional and total bone mineral, blood flow, and methylene diphosphonate (MDP) uptake. Clomid, an estrogen agonist/antagonist, was shown to protect bone from disuse loss of minerals by retarding trabecular and cortical resorption
Studies of the nucler equation of state using numerical calculations of nuclear drop collisions
A numerical calculation for the full thermal dynamics of colliding nuclei was developed. Preliminary results are reported for the thermal fluid dynamics in such processes as Coulomb scattering, fusion, fusion-fission, bulk oscillations, compression with heating, and collisions of heated nuclei
Towards Observing the Intercommutation of Flux Tubes in Superconductors
We propose a simple experiment to investigate the intercommutation of flux
tubes in type II superconductors. Using this method the intercommutation of
strings can be observed directly and the dependence of intercommutation on the
angle of crossing of strings can also be analyzed.Comment: 8 pages (LATEX), three figures included at the end of the paper,

Sustainability Education at the University of Dayton
To prepare for this Researched Argument writing assignment, I completed a research proposal that involved drafting a research question and creating a general timeline for conducting reseach leading up to this project\u27s final submission. I then analyzed ten different sources through creating an annotated bibliography that examined the credibility, content, and relevance of each resource in relation to my paper\u27s topic. In addition to collecting resouces, I personally attended SAP events and interviewed the SAP student leader in order to understand the innerworkings of sustainability education at the University of Dayton. I then composed a draft that was analyzed by my professor and reviewed by my peers before the project\u27s final submission.
