    In:  Supplement to: Tantawy, Abdel Aziz A; Keller, Gerta; Pardo, Alfonso (2009): Late Maastrichtian Volcanism in the Indian Ocean: Effects on Calcareous Nannofossils and Planktic Foraminifera. Palaeogeography, Palaeoclimatology, Palaeoecology, 284(1-2), 63-87, https://doi.org/10.1016/j.palaeo.2009.08.025

    Description: The biotic effects of volcanism have long been the unknown factors in creating biotic stress, and the contribution of the Deccan volcanism to the K-T mass extinction remains largely unknown. Detailed studies of the volcanic-rich sediments of Indian Ocean Ninetyeast Ridge Sites 216 and 217 and Wharton Basin Site 212 reveal that the biotic effects of late Maastrichtian volcanism on planktic foraminifera and calcareous nannofossils are locally as severe as those of the K-T mass extinction. The biotic expressions of these high stress environments are characterized by the Lilliput effect, which includes reduced diversity by eliminating most K-strategy species, and reduction in specimen size (dwarfing), frequently to less than half their normal adult size of both r-strategy and surviving K-strategy species. In planktic foraminifera, the most extreme biotic stress results are nearly monospecific assemblages dominated by the disaster opportunist Guembelitria, similar to the aftermath of the K-T mass extinction. The first stage of improving environmental conditions results in dominance of dwarfed low oxygen tolerant Heterohelix species and the presence of a few small r-strategy species (Hedbergella, Globigerinelloides). Calcareous nannofossil assemblages show similar biotic stress signals with the dominance of Micula decussata, the disaster opportunist, and size reduction in the mean length of subordinate r-strategy species particularly in Arkhangelskiella cymbiformis and Watznaueria barnesiae. These impoverished and dwarfed late Maastrichtian assemblages appear to be the direct consequences of mantle plume volcanism and associated environmental changes, including high nutrient influx leading to eutrophic and mesotrophic waters, low oxygen in the water column and decreased watermass stratification.

    Description / Table of Contents: Zusammenfassung Ein Finite-Differenzen-Verfahren findet Anwendung zur Berchnung der Wärmeübertragungsleistung mittels Konvektion und Strahlung an Rippen, die rechteckige, trapezförmige, dreieckige und konkav-parabolische Formen besitzen. Die Berechnungen setzen eine eindimensionale, stetige Wärmeleitung in den Rippen voraus und vernachlässigen den Strahlungsaustausch zwischen aneinandergrenzenden Rippen und zwischen den Rippen und ihrer Oberfläche. Für den betrachteten Bereich der thermischen und geometrischen Parameter wurde herausgefunden, daß die Veränderung der Wärmeübertragungsrate und des Rippenwirkungsgrades der anderen Profilformen im Bereich von 11 Prozent im Vergleich zur Rechteckform liegen. Der Einfluß der Profilform ist am stärksten, wenn die Biot-ZahlBi und die StrahlungszahlN r im Vergleich zu 1 klein sind. Aufgrund einiger einschränkender Annahmen sollten die Ergebnisse nur für die Voruntersuchungen und den Vorentwurf benutzt werden, insbesondere wenn es sich um eine Rippenanordnung und nicht um eine Einzelrippe handelt.
    Notes: Abstract A finite difference method is used to predict the performance of convecting-radiating fins of rectangular, trapezoidal, triangular, and concave parabolic shapes. The analysis assumes one-dimensional, steady conduction in the fin and neglects radiative exchange between adjacent fins and between the fin and its primary surface. For the range of thermal and geometrical parameters investigated, the variation of heat transfer rate and the fin efficiency with other profile shapes was found to be within 11 percent of the rectangular shape. The effect of profile shape is most pronounced when the Biot number,Bi, and radiation number,N r, are small compared to unity. Because of several limiting assumptions, the results would be used only for preliminary analysis and design particularly when a fin assembly is involved rather than an individual fin.

    Notes: Summary We consider the numerical solution of the Tricomi problem. Using a weak formulation based on different spaces of test and trial functions, we construct a new Galerkin procedure for the Tricomi problem. Existence, uniqueness, and uniform stability of the approximate solution is proven, and a priori error bounds are given.

    Notes: Summary We consider a class of steady-state semilinear reaction-diffusion problems with non-differentiable kinetics. The analytical properties of these problems have received considerable attention in the literature. We take a first step in analyzing their numerical approximation. We present a finite element method and establish error bounds which are optimal for some of the problems. In addition, we also discuss a finite difference approach. Numerical experiments for one- and two-dimensional problems are reported.
