Hawking Radiation in the Ghost Condensate is Non-Thermal

We consider a Schwarzschild black hole immersed in a ghost condensate background. It is shown that the Hawking radiation in the quanta of small perturbations around this background is highly suppressed- in particular it is not given by a thermal spectrum. This result is in accord with observations that such black holes can be used to violate the generalized second law of thermodynamics, and thus cannot have a standard entropy/area relation.Comment: 26 pages; v2: reference added, missing Christoffel symbols included in appendix, minor typos corrected in equations (39) and (50

Out-of-field teaching in Australian secondary schools

This report considers the extent to which Australian secondary school teachers are teaching subjects other than those in which they have specialised. It provides new data on the extent of out-of-field teaching overall and in a selection of subject areas, based on further analysis of the 2013 Staff in Australia’s Schools (SiAS) survey. In addition, the report uses new questions in the SiAS 2013 survey to assess the proportion of students affected by out-of-field teaching in selected subjects

On finite--temperature and --density radiative corrections to the neutrino effective potential in the early Universe

Finite-temperature and -density radiative corrections to the neutrino effective potential in the otherwise CP-symmetric early Universe are considered in the real-time approach of Thermal Field Theory. A consistent perturbation theory endowed with the hard thermal loop resummation techniques developed by Braaten and Pisarski is applied. Special attention is focused on the question whether such corrections can generate any nonzero contribution to the CP-symmetric part of the neutrino potential, if the contact approximation for the W-propagator is used.Comment: 11 pages, revtex styl

AN ECONOMIC EVALUATION OF LOW INVESTMENT SWINE PRODUCTION SYSTEMS

This publication summarizes an evaluation of smaller and lower investment swine production systems. The systems analyzed range from pasture operations with production during the warmer months to rather intense year-round use of remodeled buildings. In each case the system emphasizes use of facilities that can be constructed and remodeled by the farm operator. The report includes one section for each type of hog production: feeder pig production, farrow-to-finish operations and hog finishing.Livestock Production/Industries,

Modulation of internuclear communication in multinuclear Ruthenium(II) polypyridyl complexes

The syntheses and characterisation of a series of mononuclear and dinuclear ruthenium polypyridyl complexes based on the bridging ligands 1,3-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]benzene, 1,4-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]benzene, 2,5-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]thiophene, 2,5-bis-[5-pyrazinyl-1H-1,2,4-triazol-3-yl]thiophene are reported. Electrochemical studies indicate that in these systems, the ground state interaction is critically dependent on the nature of the bridging ligand and its protonation state, with strong and weak interactions being observed for thiophene- and phenylene-bridged complexes, respectively

Suppression of Bremsstrahlung at Non-Zero Temperature

The first-order bremsstrahlung emission spectrum is $\alpha d\omega/\omega$ at zero temperature. If the radiation is emitted into a region that contains a thermal distribution of photons, then the rate is increased by a factor $1+N(\omega)$ where $N(\omega)$ is the Bose-Einstein function. The stimulated emission changes the spectrum to $\alpha Td\omega/\omega^{2}$ for $\omega\ll T$. If this were correct, an infinite amount of energy would be radiated in the low frequency modes. This unphysical result indicates a breakdown of perturbation theory. The paper computes the bremsstrahlung rate to all orders of perturbation theory, neglecting the recoil of the charged particle. When the perturbation series is summed, it has a different low-energy behavior. For $\omega\ll\alpha T$, the spectrum is independent of $\omega$ and has a value proportional to $d\omega/\alpha T$ .Comment: 16 pages (plain TeX), figures available on reques

CRITICAL ECONOMIC FACTORS FOR SUCCESS OF A BIOMASS CONVERSION PLANT FOR AGRICULTURAL RESIDUE, YARD RESIDUE AND WOOD WASTE IN FLORIDA

This model evaluates the potential success of a cellulosic ethanol plant in Florida. Critical Economic factors of the plant were simulated to assess the ability of this project. These critical factors include the feedstock to be used, the cost of the facility, transportation costs and the discount rate for the net present value (NPV). Results and observations are presented in this paper.Biofuels, renewable energy, cellulosic ethanol, biomass, Agribusiness, Community/Rural/Urban Development, Crop Production/Industries, Financial Economics, Production Economics, Productivity Analysis, Resource /Energy Economics and Policy, Risk and Uncertainty,

Student Demand Projections: Supporting Analysis: Gippsland Tertiary Education Plan

There is considerable interest in the provision of, and access to, tertiary education within Victoria by the State Government. In 2010, a Tertiary Education Plan was released by the Government, detailing various targets and policy objectives in this sector. Despite a change of Government, the broad objectives in the plan continue to be pursued. As such, a number of more specific plans, based on geographic locations within Victoria, are being constructed. One such plan is being constructed for Gippsland. An Expert Panel has been formed to create the plan for Gippsland, chaired by Professor Kwong Lee Dow. This document provides supporting analysis for the Expert Panel to use in the formation of the Gippsland Tertiary Education Plan. Specifically, this document provides a modelling of tertiary demand in the Gippsland region. It provides three projections of attendance rates at technical and vocational courses, and tertiary courses, for persons aged 18-65 in the Gippsland region. For the purpose of this project, Gippsland is divided into 6 Local Government Areas (LGA). These are Baw-Baw, Bass Coast, East Gippsland, La Trobe City, South Gippsland and Wellington

Gauge Independence of Limiting Cases of One-Loop Electron Dispersion Relation in High-Temperature QED

Assuming high temperature and taking subleading temperature dependence into account, gauge dependence of one-loop electron dispersion relation is investigated in massless QED at zero chemical potential. The analysis is carried out using a general linear covariant gauge. The equation governing the gauge dependence of the dispersion relation is obtained and used to prove that the dispersion relation is gauge independent in the limiting case of momenta much larger than $eT$. It is also shown that the effective mass is not influenced by the leading temperature dependence of the gauge dependent part of the effective self-energy. As a result the effective mass, which is of order $eT$, does not receive a correction of order $e^2T$ from one loop, independent of the gauge parameter.Comment: Revised and enlarged version, 14 pages, Revte
