    Brane Rotating Symmetries and the Fivebrane Equations of Motion

    Get PDF
    We show that the fully covariant equations of motion for the M-theory fivebrane can be interpreted as charge conservation equations. The associated charges induce `shift'-symmetries of the scalar, spinor and gauge-fields of the fivebrane, so allowing an interpretation of all these fields as Goldstone fields. We also find that the fivebrane possesses a new symmetry that is part of the GL(32) automorphism group of the eleven dimensional supersymmetry algebra.Comment: 15 pages, late

    A Calibration Bound for the M-Theory Fivebrane

    Get PDF
    We construct a covariant bound on the energy-momentum of the M-fivebrane which is saturated by all supersymmetric configurations. This leads to a generalised notion of a calibrated geometry for M-fivebranes when the worldvolume gauge field is non-zero. The generalisation relevant for Dp-branes is also given.Comment: 9 pages, LaTeX2e, uses vmargin.sty. Typos corrected, a reference and a new discussion on conserved charges added. v4: A typo in the expression for the D-fourbrane energy correcte

    On the Energy Momentum Tensor of the M-Theory Fivebrane

    Get PDF
    We construct the energy momentum tensor for the bosonic fields of the covariant formulation of the M-theory fivebrane within that formalism. We then obtain the energy for various solitonic solutions of the fivebrane equations of motion.Comment: 12 pages, LaTeX2e, uses vmargin.sty and amstex.st

    New perspectives - approaches to medical education at four new UK Medical Schools

    Get PDF
    To create more UK doctors, the government has funded an increase in medical student numbers of 57% (from 3749 to 5894)1 between 1998 and 2005. This has been done by increasing student places at existing medical schools; creating shortened programmes open to science graduates; “twinning” arrangements, which host an existing curriculum at a new site; and four entirely new schools (table 1). Through reflection on our experiences and the literature evidence, we examine to what extent these new schools have a common vision and approach to undergraduate medical education, and we discuss the rationale for and likely outcomes of these new ventures

    The Australian Paradox

    Get PDF
    Nutrients recently became the target of an unprecedented internet campaign by an individual who disagrees with the content and conclusions of a paper published in the journal last year, viz. “The Australian Paradox: A Substantial Decline in Sugars Intake over the Same Timeframe that Overweight and Obesity Have Increased” by Alan W. Barclay and Jennie Brand-Miller, Nutrients 2011, 3, 491–504. Regrettably, his criticism has extended to the journal and its peer review processes for permitting publication of the article. [...

    Fulfilling Lives: Supporting people with multiple needs, Evaluation Report, Year 1

    Get PDF
    This report is prepared for the Big Lottery Fund (the Fund) by the national evaluationteam and provides emerging findings and lessons learned from the first year of thenational evaluation of the Fulfilling Lives: Supporting people with multiple needsinitiative hereafter referred to as Fulfilling Lives (multiple needs).The national evaluation has been designed to determine the degree to which the initiativeis successfully achieving its aims and how they are being achieved. The evaluation will beboth formative and summative in nature, in that, it will inform the ongoing design and delivery of Fulfilling Lives (multiple needs) and its component projects as well as assessoverall achievements and value for money to inform future decision and policy making.Within this context, the evaluation has a number of objectives:— To track and assess the achievements of the initiative and to estimate the extent to whichthese are attributable to the projects and interventions delivered.— To calculate the costs of the projects and the corresponding value of benefits to theexchequer and wider society. This will enable an assessment of value for money of theprogramme and for individual interventions.— To identify what interventions and approaches work well, for which people, families andcommunities and in which circumstances and contexts.— To assess the extent to which the Big Lottery Fund's principles are incorporated into projectdesign and delivery and to determine the degree to which these principles affect successfuldelivery and outcomes.— To explore project implementation, understand problems faced and to facilitate theidentification of solutions and lessons learned
