Radiation Transport Modeling Of Beam-Target Experiments For The Aaa Project: Quaterly Report, William Culbreth

Reactor Campaign (TRP)

The national development of technology to transmute nuclear waste depends upon the generation of high energy neutrons produced by proton spallation. Proton accelerators, such as LANSCE at the Los Alamos National Laboratory, are capable of producing 800 MeV protons. By bombarding a lead/bismuth target, each proton may generate 500 or more neutrons that can activate fission products or induce the fission of transuranic isotopes.

The Monte Carlo radiation transport code MCNPX developed at LANL is an important tool in the design of transmuter technology. It must be validated, however, for the neutron energy that will be employed. Experiments are being …

Religious Life, Sandra Marie Schneiders

Jesuit School of Theology

Religious life is a generic term for a variety of forms of Christian life that originated, as a radical response to the gospel, in the rst century and continue to develop in the present, predominantly among Roman *Catholics and *Eastern Orthodox but also, especially recently, among Protestants and Anglicans. The Protestant community of *Taize in France has fostered ecumenical exchange.

Redshifts And Luminosities For 112 Gamma-Ray Bursts, Bradley E. Schaefer, Ming Deng, David L. Band

Faculty Publications

Two different luminosity indicators have recently been proposed for gamma-ray bursts that use gamma-ray observations alone. They relate the burst luminosity (L) with the time lag between peaks in hard and soft energies (τlag) and the spikiness or variability of the burst's light curve (V). These relations are currently justified and calibrated with only six or seven bursts with known redshifts. We have examined BATSE data for τlag and V for 112 bursts. (1) A strong correlation between τlag and V exists, and it is exactly as predicted from the two proposed relations. This is proof that both luminosity indicators …

Hanford Radioactivity In Salmon Spawning Grounds, Government Accountability Project, Norm Buske

Government Accountability Project (GAP)

The public has expressed concern that radioactivity from Hanford’s wartime nuclear weapons production might contaminate salmon spawning grounds in the Columbia River. Salmon hatchlings (alevin) grow among the gravels in the riverbed, where they are susceptible to environmental stresses that include toxic chemicals and radioactivity. Some people worry that radioactivity from Hanford will damage the alevin genetically and slowly reduce the strength of the salmon stock.

In 2001, The RadioActivist Campaign (TRAC) found a radioactive fingerprint (europium-152) of old Hanford nuclear waste in 60% of sediments lying under the Hanford Reach and in 7 of 10 major salmon spawning areas. …

Measuring The Speed Of Sound Of Quintessence, Christian Armendariz-Picon, Joel K. Erickson, R. R. Caldwell, Paul J. Steinhardt, V. Mukhanov

Physics - All Scholarship

Quintessence, a time-varying energy component that may account for the accelerated expansion of the universe, can be characterized by its equation of state and sound speed. In this paper, we show that if the quintessence density is at least one percent of the critical density at the surface of last scattering the cosmic microwave background anisotropy can distinguish between models whose sound speed is near the speed of light versus near zero, which could be useful in distinguishing competing candidates for dark energy.

Our Town: Local Governments Play Larger Role In Environmental Policy, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

People normally perceive environmental law to be a piecemeal of federal laws mostly concerned with terminating pollution from point sources, such as smoke stacks or water pipes. Land use law on the other hand, is normally a local undertaking, often ignoring national or even regional issues. Today’s new breed of environmental problems, such as sprawl, require that different levels of government work together to create a comprehensively planned land use strategy in order to mitigate long-term environmental degradation. Through the use of financial incentives and other tools, larger bodies of government help encourage local governments to take the necessary steps …

A Study To Determine The Impact Of The Picture Exchange Communication System On Challenging Behaviors In Adults With Autism, Stephanie M. Belsanti

Theses and Dissertations

The purpose of this study was to determine if an increase in communication skills, over an 80 week period, in adults with autism would decrease challenging behaviors. The sample in this study consisted of 3 adult males diagnosed with autism and no verbal communication skills. The participants were between the ages of 24 and 27 and attended a data treatment center, which was used as the training environment in the current study.

The Picture Exchange Communication System was the primary treatment for three adults who have no verbal language and are diagnosed with autism. Treatment sessions were conducted throughout the …

Magnetic Field Effects On Neutron Diffraction In The Antiferromagnetic Phase Of Upt3, Juana Moreno, J. A. Sauls

Faculty Publications

We discuss possible magnetic structures in UPt3 based on our analysis of elastic neutron-scattering experiments in high magnetic fields at temperatures T < TN. The existing experimental data are compatible with a true antiferromagnetic order displaying a single-q antiferromagnetic structure with three independent domains. For modest in-plane spin-orbit interactions, the Zeeman coupling between the antiferromagnetic order parameter and the magnetic field induces a rotation of the magnetic moments, but not an adjustment of the propagation vector of the magnetic order. A triple-q magnetic structure is also consistent with neutron experiments, but in general leads to a nonuniform magnetization in the crystal. New experiments involving higher fields and polarized neutrons could decide between these structures. © 2000 The American Physical Society.

Ole Miss Dietician Advises Exercise For Healthy Mind & Body, Deborah Purnell

University of Mississippi News

UNIVERSITY, Miss. – Weight gain -- that's one year-end holiday tradition most of us could live without. Although it's been widely reported that the average American gains five or more pounds during the holiday season, a recent National Institutes of Health study found that those reports are widely exaggerated. So, why all the hoopla? According to Sharon Boon, fitness coordinator at The University of Mississippi (UM), the trouble isn't necessarily the number of pounds put on but the trouble with losing them.

Method Of Solubilizing Shortened Single-Walled Carbon Nanotubes In Organic Solutions, Robert C. Haddon, Jian Chen

Chemistry Faculty Patents

Naked single-walled nanotube carbon metals and semiconductors were dissolved in organic solutions by derivatization with SOCl₂ and octadecylamine charge. Both ionic (charge transfer) and covalent solution phase chemistry with concomitant modulation of the single-walled carbon nanotubes (SWNT) band structure were demonstrated. Solution phase near-IR spectroscopy was used to study the effects of chemical modifications on the band gaps of the SWNTs. Reaction of solubilized SWNTs with dichlorocarbene led to functionalization of the nanotube walls.

Development Of Cfl-Free, Explicit Schemes For Multidimensional Advection-Reaction Equations, Hong Wang, Jiangguo Liu

Faculty Publications

We combine an Eulerian–Lagrangian approach and multiresolution analysis to develop unconditionally stable, explicit, multilevel methods for multidimensional linear hyperbolic equations. The derived schemes generate accurate numerical solutions even if large time steps are used. Furthermore, these schemes have the capability of carrying out adaptive compression without introducing mass balance error. Computational results are presented to show the strong potential of the numerical methods developed.

Testing A Fourier Accelerated Hybrid Monte Carlo Algorithm, Simon Catterall, Sergey Karamov

Physics - All Scholarship

We describe a Fourier Accelerated Hybrid Monte Carlo algorithm suitable for dynamical fermion simulations of non-gauge models. We test the algorithm in supersymmetric quantum mechanics viewed as a one-dimensional Euclidean lattice field theory. We find dramatic reductions in the autocorrelation time of the algorithm in comparison to standard HMC.
