    The flow around a surface mounted cube: a characterization by time-resolved PIV, 3D Shake-The-Box and LBM simulation

    The flow around a surface mounted cube with incoming turbulent or laminar boundary layer has been topic of many experimental and numerical investigations in the past decades. Despite its simple geometry the fl...

    Eu2+ and Eu3+ based “concentrated phosphors” as converters for UV LED light: two approaches and two new examples

    The absolute majority of phosphors are composed of a host lattice and some percentage of an activator. At higher activator concentrations the concentration quenching occurs. However, there are phosphors in whi...

    Eulerian and Lagrangian Insights into a Turbulent Boundary Layer Flow Using Time Resolved Tomographic PIV

    Turbulent boundary layer (TBL) flow consists of manifold temporal and spatial scales and is governed by the organization and decay of self-sustaining coherent flow structures driven by entrained high momentum ...

    The route of migration of lymphocytes from blood to spleen and mesenteric lymph nodes in the pig

    Porcine peripheral blood lymphocytes were labelled with tritiated uridine in vitro and transfused into normal young pigs. Serial biopsies were taken from the spleen and mesenteric lymph nodes, and the localiza...
