In dem Beitrag wird auf ein in der deutschsprachigen Literatur neues Genre, das „Nature Writing“ eingegangen. Die Gattung feiert englischsprachigen Literaturmarkt seit geraumer Zeit Erfolge, erscheinen erst die ersten Romane und Lyrikbände, aus Naturerfahrung entstanden sind; zu erwähnen sind hier Texte von Norbert Scheuer, Esther Kinsky, Marcel Beyer, Marion Poschmann, Laura Freudenthaler, Ulr...

In this paper, we investigate the steady boundary layer flow of a non-Newtonian fluid, represented by a Sisko fluid, over a wedge in a moving fluid. The equations of motion are derived for boundary layer flow of an incompressible Sisko fluid using appropriate similarity variables. The governing equations are reduced to a single third-order highly nonlinear ordinary differential equation in the ...

The non-similar solutions for the unsteady flow of a second grade fluid wereconstructed. The method of perturbation was used for the solution of the governing non-linear equation. The results of Rajagopal et al. (Int. J. Non-Linear Mechanics, 1983) can be obtained as a special case of the presented analysis.

We introduce a general third order non-linear autonomous ODE which covers many ODEs coming from boundary layer problems, like the Falkner-Skan equation and Cheng-Minkowycz equation. Using Wiman-Valiron theory complex analytic methods recently developed, for generic cases, it is shown that all their meromorphic solutions must be rational, or rational in one exponential, then we find of them expl...
