    Feasibility study of the application of existing techniques to remotely monitor hydrochloric acid in the atmosphere

    Get PDF
    A critical evaluation of existing optical remote sensors for HCl vapor detection in solid propellant rocket plumes is presented. The P branch of the fundamental vibration-rotation band was selected as the most promising spectral feature to sense. A computation of transmittance for HCl vapor, an estimation of interferent spectra, the application of these spectra to computer modelled remote sensors, and a trade-off study for instrument recommendation are also included

    ∗\ast-SDYM fields and heavenly spaces: II. Reductions of the ∗\ast-SDYM system

    Full text link
    Reductions of self-dual Yang-Mills (SDYM) system for ∗\ast-bracket Lie algebra to the Husain-Park (HP) heavenly equation and to sl(N,{\boldmath{C}) SDYM equation are given. An example of a sequence of su(N)su(N) chiral fields (N≥2N\geq 2) tending for N→∞N\to\infty to a curved heavenly space is found.Comment: 18 page

    Leadership by the Book: Case Study of Creating a Doctoral Program in Education

    Get PDF
    Playing against type, by initiating of a doctoral program in education leadership at a respected career university is the conundrum underlying this case study in higher education leadership. Using a historical approach, the strategies used and the techniques employed to initiate a major change in an unlikely environment are discussed and linked to what the literature has to say about implementing academic change. In this particular case, what was done not only was consistent with recommendations found in the literature, but also worked to implement and sustain the doctoral program during its formative years

    On a low energy bound in a class of chiral field theories with solitons

    Get PDF
    A low energy bound in a class of chiral solitonic field theories related the infrared physics of the SU(N) Yang-Mills theory is established.Comment: Plain Latex, 8 pages, no figure

    Resummed Quantum Gravity

    Get PDF
    We present the current status of the a new approach to quantum general relativity based on the exact resummation of its perturbative series as that series was formulated by Feynman. We show that the resummed theory is UV finite and we present some phenomenological applications as well.Comment: 4 pages, 1 figure; presented at ICHEP0

    Massive Elementary Particles and Black Holes

    Full text link
    An outstanding problem posed by Einstein's general theory of relativity to the quantum theory of point particle fields is the fate of a massive point particle; for, in the classical solutions of Einstein's theory, such a system should be a black hole. We use exact results in a new approach to quantum gravity to show that this conclusion is obviated by quantum loop effects. Phenomenological implications are discussedComment: 11 pages; 1 figure; improved text relating to asymptotic safet

    Weight filtration on the cohomology of complex analytic spaces

    Get PDF
    We extend Deligne's weight filtration to the integer cohomology of complex analytic spaces (endowed with an equivalence class of compactifications). In general, the weight filtration that we obtain is not part of a mixed Hodge structure. Our purely geometric proof is based on cubical descent for resolution of singularities and Poincar\'e-Verdier duality. Using similar techniques, we introduce the singularity filtration on the cohomology of compactificable analytic spaces. This is a new and natural analytic invariant which does not depend on the equivalence class of compactifications and is related to the weight filtration.Comment: examples added + minor correction

    The development and application of audit criteria for assessing knowledge exchange plans in health research grant applications.

    Get PDF
    Background: Research funders expect evidence of end user engagement and impact plans in research proposals. Drawing upon existing frameworks, we developed audit criteria to help researchers and their institutions assess the knowledge exchange plans of health research proposals. Findings: Criteria clustered around five themes: problem definition; involvement of research users; public and patient engagement; dissemination and implementation; and planning, management and evaluation of knowledge exchange. We applied these to a sample of grant applications from one research institution in the United Kingdom to demonstrate feasibility. Conclusion: Our criteria may be useful as a tool for researcher self-assessment and for research institutions to assess the quality of knowledge exchange plans and identify areas for systematic improvement
