A questionnaire survey was used to assess job stress, strain, and health complaints associated with machine-paced poultry inspection. Four groups of employees, with differing amounts of time on the inspection line, were compared: full-time inspectors, part-time inspectors, rotating relief inspectors, and a supervisory group. Results showed full-time(More)
We present the first study of the light hadron spectrum and decay constants for quenched QCD using an O(a)-improved nearest-neighbour Wilson fermion action at β = 6.2. We compare the results with those obtained using the standard Wilson fermion action, on the same set of 18 gauge field configurations of a 243×48 lattice. For pseudoscalar meson masses in the(More)
We present results for heavy-light decay constants, using both propagating quarks and the static approximation, inO(a)-improved, quenched lattice QCD. At β = 6.2 on a 243×48 lattice we find fD = 185 + 4 − 3 (stat) + 42 − 7 (syst) MeV, fB = 160 + 6 − 6 + 53 − 19 MeV, fDs/fD = 1.18 + 2 − 2 and fBs/fB = 1.22 + 4 − 3 , in good agreement with earlier studies.(More)
NASA's Chandra X-Ray Observatory, designed for three years of operation with a goal of five years is now entering its 15-th year of operation. Thanks to its superb angular resolution, the Observatory continues to yield new and exciting results, many of which were totally unanticipated prior to launch. We discuss the current technical status, review recent(More)
– 3 – We exploit deep combined observations with Spitzer and Chandra of the Spitzer Wide-area Infrared Extragalactic Survey (SWIRE) in the ELAIS-N1 region, to investigate the nature of the faint X-ray and IR sources in common, to identify AGN/starburst diagnostics, and to study the sources of the X-ray and IR cosmic backgrounds (XRB and CIRB). In the(More)
