چکیده
WinGeol/SedTec is a software package which simulates erosion and deposition in dependency of topography, fault movements, lithological properties and sea level. Sediment transport such as mass and suspension flows are induced by elevation or concentration differences between neighbouring cells. Grain size reduction during sediment transport is included into the model. The spatial distribution of different rock types in the source area is used to model sediment composition. Rock types are characterized by their resistance to erosion and grain size reduction during sediment transport. Input data for simulation include elevation, lithology, fault data and tabular data from various data sets such as sea level curves and control points. Faults are defined by their geometry, geographic position, time interval of activity, and a displacement vector. Examples simulated with WinGeol/SedTec include landscape deformations due to translation and rotations of several fault blocks, erosion and deposition along a steep scarp and sediment transport and grain size distributions in sedimentary basins such as the Pleistocene Mitterndorf basin in Austria. Das Softwarepaket WinGeol/SedTec simuliert Erosion und Sedimentation in Abhängigkeit von Topographie, Störungsbewegungen, Lithologie und Meeresspiegel. Sedimenttransport wie etwa Massenströme und Suspensionsströme werden dabei durch Höhenoder Konzentrationsunterschiede zwischen benachbarten Zellen ausgelöst. Die Reduktion von Korngrößen während des Transports wird genauso berücksichtigt wie die räumliche Verteilung verschiedener Gesteinstypen im Abtragungsgebiet, die wesentlich die Sedimentzusammensetzung beeinflussen. Die verschiedenen Gesteinstypen sind im Wesentlichen durch ihre Widerstandsfähigkeit gegenüber Erosion und durch eine spezifische Korngrößenreduktion während des Transports charakterisiert. Eingangsdaten für die Simulation sind Höhenmodelle, Lithologien, Störungsdaten und Datentabellen, wie Meeresspiegelkurven und/oder Kontrollpunkte. Störungen werden durch ihre Geometrie, ihre geographische Lage, das Zeitintervall ihrer Aktivität und durch einen Verschiebungsvektor definiert. Fallbeispiele, die mit WinGeol/SedTec simuliert werden können, umfassen Landschaftsveränderungen durch Translationen und Rotationen von Störungsblöcken, Erosion und Ablagerung an Steilhängen, sowie Sedimenttransport und Korngrößenverteilungen in Sedimentbecken wie etwa die pleistozäne Mitterndorfer Senke im Wiener Becken (Österreich).

متن کاملThe Low Mortality of a Learned Society
This study addresses the mortality of the members of a learned society. Following the literature on the social gradient of mortality, members of a learned society should exhibit much lower death rates than other social groups. We use biographical records from the members of the Austrian Academy of Sciences between 1847 and 2005 and compare their mortality to Austrian life table death rates of t...

Iran’s Sarcheshmeh copper industries with an annual production of 120,000 tones are the biggest of it’s kind in South Asia. The main method of production is pyrometallurgical matte making in two reverberatory furnaces which use direct–bond magnesite-chromite refractories supplied by German and Austrian companies. Following a recent major overhaul, bricks in contact with slag, matte and furnace ...
