The future of global land use

Kreidenweis, Ulrich (2018)

Global land-use change is a main driver of two of the biggest environmental alterations threatening human well-being: climate change and the decline in biodiversity. Over recent decades, a growing and wealthier population has requested more agricultural products, and this demand has been satisfied by expanding agricultural areas and intensifying production. However, this has posed consequences....

New Products of Defense Secretion in South East Asian Whip Scorpions (Arachnida: Uropygi: Thelyphonida)

Haupt, Joachim ; Müller, Frank (2004)

Secretion products from the opisthosomal defense gland of south east Asian whip scorpions were identified for the first time by gas-chromatography and mass-spectrometry. Specimens of the genera Hypoctonus, Typopeltis and Ginosigma were tested. While some ingredients are present in large concentrations, others are possibly only side products and may be synthesized more incidentally. For this rea...

Purpose-designed technogenic materials for sustainable urban greening

Flores Ramírez, Eleonora (2018)

Background: Urban green areas provide a number of desirable ecosystem services for the environment and city dwellers. However, the substrate preparation for the greenery installation mostly implies the mining and erosion of valuable natural soils. Therefore, the objective of this work is to design a Technosol based on a mixture of mainly recycled materials, to sustain vegetation and to lower t...

Quantification of cooling effects and water demand of urban facade greenings

Hölscher, Marie-Therese (2018)

Higher air temperatures in cities lead to increased heat stress for the urban population, especially during the night in hot summer periods. Facade greening is often discussed as a promising mitigation strategy as it can be applied on building surfaces where the heat stress is mainly caused. It reduces the stored energy in the building mass through shading and transpirative cooling and addition...

Wem gehört die Stadt? Wer darf wohnen – wer muss gehen? Wer entscheidet darüber? Und mit welchen Mitteln? Ein halbes Jahr lang begleiteten Christine Bock und Ulrich Pappenberger die Mieter*inneninitiative Kotti & Co um zu verstehen, wie Sozialmieter*innen zu einflussreichen Akteuren der Berliner Stadt- und Wohnungspolitik wurden. Die Studie folgt der Akteur-Netzwerk-Theorie und erzählt von der ...

P-T-X phase diagrams of carbonates

Müller, Jan (2018)

This thesis has been devoted to the high pressure (HP) and high temperature (HT) effects on the FeCO3-MgCO3 and the CaCO3-MgCO3 solid solution series. In more detail, I have investigated the vibrational behavior of the FeCO3-MgCO3 solid solution series under HP/HT conditions across the electronic high spin (HS) to low spin (LS) transition up to 60 GPa and 700 K and I have furthermore determined...

Reiterer, Alexander ; Egly, Uwe ; Vicovac, Tanja ; Mai, Enrico ; Moafipoor, Shahram ; Grejner-Brzezinska, Dorota A. ; Toth, Charles K. (2010)

Artificial Intelligence (AI) is one of the key technologies in many of today's novel applications. It is used to add knowledge and reasoning to systems. This paper illustrates a review of AI methods including examples of their practical application in Geodesy like data analysis, deformation analysis, navigation, network adjustment, and optimization of complex measurement procedures. We focus on...

Determining the Growth and Vitality of Micro-Organisms in Carpets and Mattresses in Non-Problem Dwellings by Measuring CO2 Released during Respiration

Kemp, Peter ; Neumeister-Kemp, Heike ; Koch, C. ; Lysek, Gernot ; Murray, Frank (2002)

Bedroom carpets and mattresses devoid of any reported or observed moisture damage or problems were analysed as sources of indoor fungal growth by determining the amount of CO2 released from respiration by micro-organisms living in furnishings. Dust was extracted from the carpets and mattresses using a Kirby G5 vacuum cleaner. The basal respiration rate of the dust samples without moisture added...

Urban planning practice under neo-customary land tenure

Akaateba, Millicent Awialie (2018)

Contemporary discourses on land policy in sub-Saharan African countries have shifted from polarised debates that hitherto promoted formal land administration or romanticised customary tenure systems. Recent policy trends have emphasised the integration of customary and state tenure systems as a nascent strategy to achieve equitable land delivery. Conceptually embedded in the exploratory concept...

Compositional alterations of petroleum as a result of expulsion and migration in the North Sea Central Graben petroleum system

Ziegs, Volker (2018)

The Mandal Formation, the principal source rock in the well-explored North Sea Central Graben, has been identified as a locally very inefficient expeller of its generated products, although having charged numerous petroleum accumulations in that basin. This unusual behaviour for marine shales makes the Mandal Formation an interesting natural laboratory to re-assess the factors controlling gener...

The calculation of the lunar series on classic Maya monuments

Fuls, Andreas (2007)

Archaeological and historical evidence clearly shows that the Lunar Series of mythical dates were calculated backward—that is, they were often determined from the date on which the monument was erected using a specific formula to calculate the age of the moon. In this article, I present a high-precision adjustment technique that confirms the “Palenque formula” using Lunar Series data from recen...

Die vorliegende Arbeit befasst sich mit den Auswirkungen von Shopping-Centern auf Innenstädte, wobei der Fokus auf kleineren Mittelstädten mit 50.000 bis 100.000 Einwohnern liegt. Durch eine systematische Analyse von Städten, welche über mindestens ein Shopping-Center verfügen, werden kurz-, mittel- und langfristige Auswirkungen der Eröffnung auf die Gesamtentwicklung des jeweiligen Standortes ...

Regional planning and the energy efficiency purposes

Khalili, Mahmoudreza (2018)

The background concepts based on which this research is carried out could be divided into four categories; first, the climate change impacts are clearly visible in urban regions throughout Iran, including Tehran Region; second, despite the national regulations set to reduce the use of fossil energies, the use of those energies are still high in different consumption types; third, the Tehran Met...

Simulations of nutrient emissions from a net cage aquaculture system in a Brazilian bay

Matta, Elena ; Selge, Florian ; Gunkel, Günter ; Rossiter, Karina ; Jourieh, Ayman ; Hinkelmann, Reinhard (2016)

Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to dee...

Prinzipien der Architekturdarstellung : die Verwendung der Orthogonalprojektion in Palladios »I quattro libri dell' architettura« (1570).

Valdivia Steel, Lorena Cristina (2018)

The term »orthogonal projection« refers to the representation format which marks the source of the present study of the principles of the architectural representation in Andrea Palladio’s printed works »I quattro libri dell’ architettura« published in 1570. Palladio’s special position in architectural history is not only due to his many built works but at least equally to his numerous orthogona...

An ALE method for penetration into sand utilizing optimization-based mesh motion

Aubram, Daniel ; Rackwitz, Frank ; Wriggers, Peter ; Savidis, Stavros A. (2015)

The numerical simulation of penetration into sand is one of the most challenging problems in computational geomechanics. The paper presents an arbitrary Lagrangian–Eulerian (ALE) finite element method for plane and axisymmetric quasi-static penetration into sand which overcomes the problems associated with the classical approaches. An operator-split is applied which breaks up solution of the go...

A comparison of different seismological and geotechnical parameters for site characterization

Boxberger, Tobias (2018)

The geometry of the subsoil structure, the soil types involved and the variation in their properties with depth, lateral discontinuities and surface topography are causes of lateral variation in earthquake-induced ground motion, over relatively small scales, referred to as "site effects" The modification of ground motion can manifest itself through amplification at particular frequencies (the ...

Homogeneous equilibrium model for geomechanical multi-material flow with compressible constituents

Aubram, Daniel (2016-04-09)

Multi-material flow generally describes a situation where several distinct materials separated by sharp material interfaces undergo large deformations. In order to model such flow situations in the context of geomechanics and geotechnical engineering, a theoretical framework is presented which introduces a possible two-phase coupled saturated granular material behavior among the different mater...

High-resolution shear wave reflection seismics and borehole seismics as tools for the imaging and the characterization of near-surface subrosion structures

Wadas, Sonja Halina (2018)

Subrosion and the resulting structures, such as sinkholes and depressions, pose a great hazard risk. They can cause damage to buildings and infrastructure, and lead to life-threatening situations. But compared to other natural hazards, like earthquakes and tsunamis, very little is known about the generation processes or the possibilities of forecasting. Germany suffers from a widespread sinkhol...

Driving forces and barriers for adaption strategies against the urban heat stress hazard in Berlin, Germany

Donner, Julie (2018)

Climate change is here and mitigation efforts will not be enough to stop it. We need to adapt to its unavoidable impacts. At the same time, increasing anthropogenic influence on urban climates is leading to worsening urban heat stress. Increased amounts of impervious area, dark surfaces, and the barrier effect of large buildings reduce the ability of especially dense, inner-city areas to cool t...
