    Proton emission induced by polarized photons

    Get PDF
    The proton emission induced by polarized photons is studied in the energy range above the giant resonance region and below the pion emission threshold. Results for the 12C, 16O and 40Ca nuclei are presented. The sensitivity of various observables to final state interaction, meson exchange currents and short range correlations is analyzed. We found relevant effects due to the virtual excitation of the Δ\Delta resonance.Comment: 12 pages, 11 figures, 1 tabl

    Effects of state dependent correlations on nucleon density and momentum distributions

    Full text link
    The proton momentum and density distributions of closed shell nuclei are calculated within a model treating short--range correlations up to first order in the cluster expansion. The validity of the model is verified by comparing the results obtained with purely scalar correlations with those produced by finite nuclei Fermi Hypernetted Chain calculations. State dependent correlations are used to calculate momentum and density distributions of 12C, 16O, 40Ca, and 48Ca, and the effects of their tensor components are studied.Comment: 16 pages, latex, 8 figures, accepted for publication in Phys.

    Slip over a lubricant impregnated surface in pressure-driven flow

    Get PDF
    Paper no. 307A novel non-wetting surface known as slippery liquid-infused porous surface (SLIPS) or lubricant impregnated surface (LIS) has been reported recently. This work aims to investigate effective slip or drag reduction arising from pressure-driven flow through a microchannel bounded by SLIPS. Numerical simulation was performed for the flow of both the lubricating and working fluids inside and immediately outside the microtextured surface. The multiphase problem is solved using the front tracking method. In this method the interface is replaced by a transitional narrow zone, which has a thickness comparable to the mesh size, and the fluid properties such as density and viscosity are constructed according to the distance from the interface. SLIPS with various pattern lengths and lubricant liquid with different viscosities are calculated and compared.postprin

    Effective slip for flow through a channel bounded by lubricant-impregnated grooved surfaces

    This study aims to investigate effective slip arising from pressure-driven flow through a slit channel bounded by lubricant-impregnated grooved surfaces. The problem for flow over longitudinal grooves is solved analytically using the methods of domain decomposition and eigenfunction expansion, while that for flow over transverse grooves is solved numerically using the front tracking method. It is found that the effective slip length and the lubricant flow rate can depend strongly on the geometry of the microstructure, the direction of flow, and the lubricant viscosity. In particular, the effective slip can be effectively enhanced by increasing the thickness of a lubricating film atop the ribs. Under the same conditions, a flow that is parallel to the lubricant-impregnated grooves will have a larger effective slip, but also a larger lubricant flow rate, when compared with the case of flow normal to the grooves. It is also shown that, in the case of transverse grooves, because of the downward displacement of the interface between the working/lubricating fluids, the effective slip length and lubricant flow rate may vary non-monotonically with the groove depth.postprin

    Anticipating Loss: Rethinking Endangerment in Heritage Futures

    Get PDF
    This is the final version. Available on open access from Taylor & Francis via the DOI in this recordThe construct of heritage relies, to a large extent, on notions of endangerment and consequential attempts to arrest or reverse processes of loss and change. The papers in this special issue engage critically with this underlying orientation, exploring the social and cultural work which is produced through efforts to avert loss. In doing so, the papers also point towards alternative ways of valuing objects, places and practices which are not solely determined by notions of endangerment and risk. We suggest three general themes which connect critical investigation of these issues across the varied natural and cultural heritage contexts through which these papers work—the inevitability of loss; the politics of loss; and the potential in loss. These themes have significant implications not only for the future of natural and cultural heritage preservation, conservation and management, but also in mapping out future research directions for critical heritage studies.Arts and Humanities Research Council (AHRC)University College LondonUniversity of YorkUniversity of Exete

    Liver rejection and its differentiation from other causes of graft dysfunction.

    Get PDF
    Numerous causes can lead to hepatic dysfunction following orthotopic liver transplantation. The most common cause is rejection, which is usually nonpreventable. The clinical presentation, time of onset, and even treatment are variable. Other causes, such as perioperative ischemic injury, vascular thrombosis, and complications of bile duct reconstruction may be preventable with good surgical technique. Infections can also be minimized by careful adjustment of immunotherapy, avoidance overimmunosuppression, and the judicious use of antibiotics. Hepatic dysfunction following orthotopic liver transplantation requires rapid assessment and proper treatment in order to prevent serious and possibly fatal complications
