    New EUV Fe IX emission line identifications from Hinode/EIS

    Full text link
    Four Fe IX transitions in the wavelength range 188--198 A are identified for the first time in spectra from the EUV Imaging Spectrometer on board the Hinode satellite. In particular the emission line at 197.86 A is unblended and close to the peak of the EIS sensitivity curve, making it a valuable diagnostic of plasma at around 800,000 K - a critical temperature for studying the interface between the corona and transition region. Theoretical ratios amongst the four lines predicted from the CHIANTI database reveal weak sensitivity to density and temperature with observed values consistent with theory. The ratio of 197.86 relative to the 171.07 resonance line of Fe IX is found to be an excellent temperature diagnostic, independent of density, and the derived temperature in the analysed data set is log T=5.95, close to the predicted temperature of maximum ionization of Fe IX.Comment: 10 pages, 3 figures, 2 tables, submitted to ApJ Letter

    A gas turbine powered aircraft auxiliary power system is described which is capable of efficiently supplying all aircraft auxiliary services both in flight and on the ground and is further capable of operating independently of the aircraft main engines. The system employs multiple gas turbine compressor stages, thereby accomplishing cabin pressurization, ventilation and heating

    Mission-Market Tension in Managing Nonprofit Organizations

    Get PDF
    Private not-for-profit organizations combine characteristics of a public sector agency with those of a private, proprietary firm. In particular, nonprofits are required to address designated social missions while breaking even financially. This structure underlies the difficulty that nonprofit organizations face in making decisions with important resource implications. Specifically, choices that would achieve maximal mission impact may differ from choices that reward the organization in purely financial terms. As result, nonprofit managers face a variety of trade-offs between mission responsive and financially rewarding actions. This paper considers some of these tradeoffs by exploring how tensions between mission and market manifest themselves in a variety of nonprofit decision making applications. The analysis is based on a set of task forces assembled by the National Center on Nonprofit Enterprise in eight areas of nonprofit decision making. The paper suggests the development of metrics to reconcile mission goals with market incentives and research on appropriate nonprofit practices in areas such as pricing, employee compensation, outsourcing, collaboration, investment, fund raising and the undertaking of commercial ventures.
