    Free school meals aim to provide a “nutritional safety net” for the poorest UK children. Yet it is estimated that up to 30% of those entitled do not take up this entitlement. In Leeds approximately 6,000 children do not take the free school meals that they are entitled to. National and local targets are for 100% take up. Phase 2 of the Leeds Free School Meal Research Project aimed to develop, implement and evaluate a series of interventions to increase the uptake of free school meals. The interventions were tested in ten Leeds schools between December 2007 and October 2008. The research was undertaken by the Department of Nutrition & Dietetics within The Centre of Food Nutrition and Health at Leeds Metropolitan University on behalf of Education Leeds

    Convective–reactive nucleosynthesis of K, Sc, Cl and p-process isotopes in O–C shell mergers

    © 2017 The Author(s). Published by Oxford University Press on behalf of the Royal Astronomical Society. We address the deficiency of odd-Z elements P, Cl, K and Sc in Galactic chemical evolution models through an investigation of the nucleosynthesis of interacting convective O and C shells in massive stars. 3D hydrodynamic simulations of O-shell convection with moderate C-ingestion rates show no dramatic deviation from spherical symmetry. We derive a spherically averaged diffusion coefficient for 1D nucleosynthesis simulations, which show that such convective-reactive ingestion events can be a production site for P, Cl, K and Sc. An entrainment rate of 10-3M⊙s-1features overproduction factors OPs≈ 7. Full O-C shell mergers in our 1D stellar evolution massive star models have overproduction factors OPm> 1 dex but for such cases 3D hydrodynamic simulations suggest deviations from spherical symmetry. γ - process species can be produced with overproduction factors of OPm> 1 dex, for example, for130, 132Ba. Using the uncertain prediction of the 15M⊙, Z = 0.02 massive star model (OPm≈ 15) as representative for merger or entrainment convective-reactive events involving O- and C-burning shells, and assume that such events occur in more than 50 per cent of all stars, our chemical evolution models reproduce the observed Galactic trends of the odd-Z elements

    Ecophysiological traits of grasses: resolving the effects of photosynthetic pathway and phylogeny

    Get PDF
    C4 photosynthesis is an important example of convergent evolution in plants, having arisen in eudicots, monocots and diatoms. Comparisons between such diverse groups are confounded by phylogenetic and ecological differences, so that only broad generalisations can be made about the role of C4 photosynthesis in
determining ecophysiological traits. However, 60% of C4 species occur in the grasses (Poaceae) and molecular phylogenetic techniques confirm that there are between 8 and 17 independent origins of C4 photosynthesis in the Poaceae. In a screening experiment, we compared leaf physiology and growth traits across several major
independent C3 & C4 groups within the Poaceae, asking 1) which traits differ consistently between photosynthetic
types and 2) which traits differ consistently between clades within each photosynthetic type
