Behagliche Monumentalität in Frankfurt

Enders, Tina (2018)

Bisherige architektursoziologische Ansätze, die den Zusammenhang von Gesellschaft und Architektur aufzuschlüsseln versuchen, beziehen sich in aller Regel nur sehr wenig bis gar nicht auf das direkte bauliche Umfeld und dessen physisch-materiellen Aspekte. Auch der Entstehungsprozess von Architekturen gerät nur selten in den Untersuchungsfokus. Zwar werden regelmäßig soziale Vorgänge in eine dir...

Die Natur als Vorbild und Partner

Steup, Lara (2018)

Der menschliche Umgang mit den natürlichen Ressourcen der Erde hat dramatische ökologische (und soziale) Folgen: Hierzu gehören der Klimawandel, der degradierte Zustand unserer Ökosysteme sowie der damit einhergehende hohe Verlust der Biodiversität. Trotz aller Bemühungen um eine nachhaltige Entwicklung konnte in diesen Bereichen bisher keine Trendwende erzielt werden. Der Wissenschaftliche Bei...

Dissolution-precipitation reactions in the system Al2O3-SiO2-H2O and the formation of Al2SiO5

Schultze, Dina (2018)

The study of mineral replacement reactions can provide detailed insight into chemical processes, if experimental simulation and natural observation are combined. Among all chemical systems, the Al2O3-SiO2-H2O is one of the most intensely studied but some of our knowledge about it is still inconsistent. Especially problematic is the inhibited reaction of corundum and quartz to Al2SiO5 polymorphs...

Effects of biogas residues on yield formation and soil organic carbon stocks

Prays, Nadia (2018)

Während der Klimarahmenkonvention der Vereinten Nationen einigte man sich auf die Bekämpfung des Klimawandels und die Einhaltung des globalen Temperaturanstiegs in diesem Jahrhundert auf unter 2°C des vorindustriellen Niveaus. Eine der Maßnahmen, um dieses Ziel zu erreichen, ist die Erhöhung des Anteils der erneuerbaren Energien, z.B. den Anteil des Biogases, das durch anaerobe Vergärung der Bi...

This paper presents a set of energy and resource intensive scenarios based on the concept of Shared Socio-Economic Pathways (SSPs). The scenario family is characterized by rapid and fossil-fueled development with high socio-economic challenges to mitigation and low socio-economic challenges to adaptation (SSP5). A special focus is placed on the SSP5 marker scenario developed by the REMIND-MAgPI...

Impact and mitigation of borehole related effects in permanent crosshole resistivity imaging: An example from the Ketzin CO2 storage site

Wagner, Florian M. ; Bergmann, Peter ; Rücker, Carsten ; Wiese, Bernd ; Labitzke, Tim ; Schmidt-Hattenberger, Cornelia ; Maurer, Hansruedi (2015)

Geoelectrical methods are particularly suited for CO2 injection monitoring due to their high sensitivity to fluid displacement processes in porous rock formations. The use of borehole electrodes is favorable for deep storage horizons. Yet data acquisition based on permanently installed borehole electrodes can be challenged by the finite extent of the electrodes, unintended borehole deviation an...

Near‐surface fault detection using high‐resolution shear wave reflection seismics at the CO2CRC Otway Project site, Australia

Beilecke, Thies ; Krawczyk, Charlotte M. ; Ziesch, Jennifer ; Tanner, David C. (2016-07-28)

High‐resolution, near‐surface, shear wave reflection seismic measurements were carried out in November 2013 at the CO2CRC Otway Project site, Victoria, Australia, with the aim to determine whether and, if so, where deeper faults reach the near subsurface. From a previous P wave 3‐D reflection seismic data set that was concentrated on a reservoir at 2 km depth, we can only interpret faults up to...

Massive carbon addition to an organic-rich Andosol increased the subsoil but not the topsoil carbon stock

Zieger, Antonia ; Klaus, Kaiser ; Ríos Guayasamín, Pedro ; Kaupenjohann, Martin (2018-05-07)

Andosols are among the most carbon-rich soils, with an average of 254 Mg ha−1 organic carbon (OC) in the upper 100 cm. A current theory proposes an upper limit for OC stocks independent of increasing carbon input, because of finite binding capacities of the soil mineral phase. We tested the possible limits in OC stocks for Andosols with already large OC concentrations and stocks (212 g kg−1 in ...

Studying soil-structure interaction effects

Petrovic, Bojana (2018)

Since earthquakes can neither be prevented nor predicted, in order to reduce damage to the built environment and human losses, the fundamental goal is to improve the design of buildings. For this purpose, variations in ground motion over short distances during earthquakes arising from both site effects (modifications of the ground motions due to changes in the shallow geological layers) and soi...
