    The Seeds of Exclusion

    First paragraph: It is in the context of all the factors relating to the social, physical and mental wellbeing of Britain in 2008 that The Salvation Army presents The Seeds of Exclusion report. The research findings must be read in the light of the additional pressures we have identified which may be brought to bear on individuals already living in a society which is becoming increasingly fragmented, chaotic and stressful. The Salvation Army hopes its contribution to this ongoing debate will begin to inform us all, including Government, on how we can avoid the mistakes of the past and begin to mend society

    Qualification of piezo-electric actuators for the MADMAX booster system at cryogenic temperatures and high magnetic fields

    We report on the qualification of a piezo-based linear stage for the manipulation of positions of dielectric discs in the booster of the MADMAX axion dark matter search experiment. A first demonstrator of the piezo drives, specifically developed for MADMAX, was tested at room temperature as well as at cryogenic temperatures down to 4.5 K and inside strong magnetic fields up to 5.3 T. These qualification measurements prove that the piezo-based linear stage is suited for MADMAX and fulfills the requirements.Comment: 13 pages, 9 figures, 2 table

    Shape Isomerism at N = 40: Discovery of a Proton Intruder in 67Co

    Full text link
    The nuclear structure of 67Co has been investigated through 67Fe beta-decay. The 67Fe isotopes were produced at the LISOL facility in proton-induced fission of 238U and selected using resonant laser ionization combined with mass separation. The application of a new correlation technique unambiguously revealed a 496(33) ms isomeric state in 67Co at an unexpected low energy of 492 keV. A 67Co level scheme has been deduced. Proposed spin and parities suggest a spherical (7/2-) 67Co ground state and a deformed first excited (1/2-) state at 492 keV, interpreted as a proton 1p-2h prolate intruder state.Comment: 4 pages, 5 figures, preprint submitted to Physical Review Letter

    Black carbon as an additional indicator of the adverse health effects of airborne particles compared with PM10 and PM2.5.

    Current air quality standards for particulate matter (PM) use the PM mass concentration [PM with aerodynamic diameters ≀ 10 ΞΌm (PM(10)) or ≀ 2.5 ΞΌm (PM(2.5))] as a metric. It has been suggested that particles from combustion sources are more relevant to human health than are particles from other sources, but the impact of policies directed at reducing PM from combustion processes is usually relatively small when effects are estimated for a reduction in the total mass concentration
