    Description: An 81-year-old woman had cardiac failure after surgery for oral cancer. A diagnostic workup indicated perioperative overhydration and pulmonary embolism, and chest radiography revealed a large, dense area of calcification overlying the heart, consistent with mitral annular calcification. An 81-year-old woman was transferred to the medical service with cardiac failure after surgery for oral cancer. A diagnostic workup indicated perioperative overhydration and pulmonary embolism as causative factors for her symptoms. Chest radiography revealed a large, dense area of calcification overlying the heart, consistent with mitral annular calcification. Calcification was semicircular in the location of the mitral valve, as seen on the preoperative posterior–anterior view (Panel A, arrowhead; Panel B, arrow, shows an enlarged view) and a lateral view (Panel C, arrowhead). Computed tomography revealed calcification of the posterolateral mitral-valve annulus on the axial view (Panel D, arrowhead) and . . .

    Description: In this paper, the Curitiba-centred narrative on the success of its urban planning experience will be qualified in light of the complexities of its metropolitan development trajectory. It will be claimed that the institutional vacuum that surrounds Brazilian metropolitan areas in general, and Greater Curitiba in particular, has been intensified by the emergence of a competitive and decentralised state spatial regime, which has consolidated a fragmented and neo-localist system of governance. Preliminary empirical evidence will be provided on the challenges that are being faced within the new regime in articulating socio-spatial, economic and environmental strategies in the direction of a more sustainable metropolitan future.

    Description: Using the experience of metropolitan io de aneiro, this article contributes to the broader debate on development regimes, rescaling and state spatial restructuring in razil, and its specificities in relation to the international discussion on the transformations in Atlantic Fordism. I argue that the transition from a (peripheral) development state to a competitive and rescaled regime has been accompanied by important continuities. Legitimized through discourses around development poles and trickle‐down effects, the national‐developmental regime has systematically promoted some spaces as opposed to others, without much emphasis on the social and environmental dimensions of spatial policies. The emerging competitive state spatial regime, whether in its neoliberalized, or its more recent ‘rolled‐out’ national‐developmental version, is merely expected to aggravate the historical socio‐environmental contradictions in the production of space. Moreover, scale has proven contested and strategic‐relational, both molding and being influenced by actors that seek to use scalar politics to reach their interests. My analysis suggests that, within this scenario, neither economic growth, nor regulatory and institutional strengthening, nor financial resources are likely to produce structural transformation in the inherited spaces of reater io de aneiro.

Commonly used three-electrode test cells, however, proved unreliable due to asymmetric current line distributions, causing severe distortions of impedance spectra. Finite element method (FEM) simulations can visualize these current lines at different frequencies and simulate impedance spectra at given geometries. By applying FEM simulations to a recently developed coaxial impedance test cell, limiting conditions for reliable impedance measurements could be identified. Using a reference electrode in coaxial position yields sufficiently reliable results as long as the electrode misalignment is small compared to the electrolyte thickness and edge effects are prevented.

    Description: Evolution of (a) monodisperse and (b) bidisperse drop-size distributions over time due to coalescence. / represents the fraction of initial drops remaining. ► Coalescence rate depends upon shape of drop-size distribution, and is especially sensitive to the fraction of large droplets. ► Fingerprints characteristic of the initial distribution shape remain, even when the number of drops has been reduced by 90%. ► Measurement resolution of the drop-size distribution significantly affects predicted coalescence rates. ► Coalescence rate decreases with the width of the drop-size distribution. A population balance is used to examine the effect of the shape of the initial drop-size distribution of an emulsion upon its short and long-time evolution in simple shear flow. Initial distributions that are monodisperse, multidisperse, lognormal, bimodal, multimodal, and step functions are considered. At short times, it is shown that the rate of coalescence decreases by up to 25% for step distributions and up to 75% for lognormal distributions as the width of the distribution increases. Bimodal, multidisperse and multimodal distributions show intermediate decreases in the rate of coalescence, between these two values, with increases in the distribution width. Furthermore, it is found that the initial rate of coalescence is strongly dependent upon the presence of large drops. As the number fraction of large droplets within the distribution increases, the rate of coalescence also increases. At long times, all distributions move toward an asymptotic distribution shape in which the frequency of drops decreases algebraically with drop diameter at small drop diameters, and decreases exponentially with drop diameter at large drop diameters. Though portions of each distribution showed the expected asymptotic scaling behavior at long times, each asymptotic distribution nevertheless retains ‘fingerprints’ of the respective initial distribution. Overall, the rate of coalescence for a system is bounded by the initial rate, which is a function of the initial distribution shape, and the asymptotic rate, which is dependent upon the long-time scaling behavior. Finally, it is shown that the resolution with which the drop-size distribution of an emulsion is experimentally measured can have a significant effect upon predicted rates of coalescence.

WallisDeVries, Jan P. Bakker Abstract: acents Large herbivores can create mosaics of short and tall vegetation. acents These vegetation mosaics are believed to optimise arthropod species richness. acents We compared grazed mosaics to fenced and highly grazed vegetation on salt marshes. acents Short and tall vegetation harboured very different arthropod communities. acents Surprisingly, grazed mosaics were not more diverse than homogeneous tall vegetation.
