Three-dimensional modeling of wind- and temperature-induced flows in the Icó-Mandantes Bay, Itaparica Reservoir, NE Brazil

Matta, Elena ; Selge, Florian ; Gunkel, Günter ; Hinkelmann, Reinhard (2017)

The Icó-Mandantes Bay is one of the major branches of the Itaparica Reservoir (Sub-Middle São Francisco River, Northeast Brazil) and is the focus of this study. Besides the harmful algae blooms (HAB) and a severe prolonged drought, the bay has a strategic importance—e.g., the eastern channel of the newly built water diversion will withdraw water from it (drinking water). This article presents t...

At the frontiers of integrated assessment of climate change

Schultes, Anselm Johannes (2017)

Integrated Assessment Modeling is the prevailing paradigm for the assessment of climate change impacts, mitigation policies, and transformation pathways. Model results were a decisive impulse for the international community to commit itself to stabilize global warming at well below 2° C temperature rise. However, climate policies in place or pledged as of 2015 fall short of what science finds a...

Wissenschaft zwischen Lebensform und Karrierejob

Rogge, Jan-Christoph (2017)

Die These, die in der Dissertation entfaltet wird, lautet, dass mit dem wissenschaftlichen Beruf heute widersprüchliche Karriereanforderungen verbunden sind: Die traditionellen Sozial- und Organisationsideen der Wissenschaft sind noch immer wirkmächtig. Die Wissenschaft soll nach wie vor Lebensform und Berufung sein. Zugleich ist die Wissenschaft aber von einem Transformationsprozess erfasst, d...

Roles of organic-inorganic interactions in the generation of petroleum as exemplified by Lower Palaeozoic petroleum systems, Europe

Yang, Shengyu (2017)

The clay-rich Lower Carboniferous Bowland Shale (England) and the uranium-rich Cambro-Ordovician Alum Shale (Northern Europe), both deposited in marine environments, are characterized by dominating gaseous and aromatic compounds in pyrolysates. Therefore, the kerogens in both of these shales can be classified as type III from classical perspectives, which is not consistent with the depositional...

Erprobung experimentell basierter Evolutionsgleichungen für ein Werkstoffgesetz von Beton

Vogdt, Fritz (2017)

Versagenssimulationen von Betonbauteilen unter mehrdimensionalen Beanspruchungen sind bis heute eine Herausforderung. Eine Vielzahl bisheriger Materialmodelle ist aus theoretischer Sicht bereits für eine Simulation von Betonkonstruktionen bis zum Versagen geeignet. Häufig beschränkt sich ihre Anwendung aber auf die rechnerische Bestätigung bekannter Versuche, da sie einer belastungsartspezifisc...

Long-term monitoring of lakes in the northern central European lowlands using optical and radar remote sensing imagery

Heine, Iris Elisabeth (2017)

The glacial landscape of the northern Central European lowlands in Germany and Poland is characterized by a large number of lakes. These lakes fulfill important ecosystem services, however, they are sensitive to climate change, land use changes, and human impact. Very few of them are regularly monitored in situ. This thesis tests the potential of remote sensing imagery for the long-term monitor...

Definition eines aktualisierten Berufsbilds des Architekten in Algerien

Mazoun, Redha (2017)

Der Beruf des Architekten ist dynamisch und entwickelt sich stetig. Das bedeutet, dass die architektonischen Dienstleistungen, gleichsam mit der technologischen Entwicklung, der Globalisierung, dem sozialen Wandel, den Kundenanforderungen und den Umweltfragen wachsen, sich diversifizieren und sich ebenso verkomplizieren. Der Architekt muss in der Lage sein, auf alle diese Herausforderungen mit ...

Efficiency and utility

Mann, Stefan ; Wüstemann, Henry (2010)

Purpose: The purpose of this paper is to develop the argument that the link between efficiency and utility was strongest in the twentieth century. This would not only explain the growing focus on efficiency in the past, but also suggest that the importance of efficiency in society is set to decrease from now on. Design/methodology/approach: The two arguments in support of the claim were: first,...

Coarse grid approaches for the shallow water model

Özgen, Ilhan (2017)

Developments in survey technology such as light detection ranging and laser-scanning are able to provide high-resolution topography data sets. In shallow water equations based modeling, the use of high-resolution topography data is generally desirable, because it is considered to be a more accurate representation of the “real world”. Indeed, high-resolution discretization of topography leads to...

Organic matter modeling at the landscape scale based on multitemporal soil pattern analysis using RapidEye data

Blasch, Gerald ; Spengler, Daniel ; Itzerott, Sibylle ; Wessolek, Gerd (2015)

This study proposes the development of a landscape-scale multitemporal soil pattern analysis (MSPA) method for organic matter (OM) estimation using RapidEye time series data analysis and GIS spatial data modeling, which is based on the methodology of Blasch et al. The results demonstrate (i) the potential of MSPA to predict OM for single fields and field composites with varying geomorphological...

Potential of remote sensing to predict species invasions: a modelling perspective

Rocchini, Duccio ; Andreo, Veronica ; Förster, Michael ; Garzon-Lopez, Carol Ximena ; Gutierrez, Andrew Paul ; Gillespie, Thomas W. ; Hauffe, Heidi C. ; He, Kate S. ; Kleinschmit, Birgit ; Mairota, Paola ; Marcantonio, Matteo ; Metz, Markus ; Nagendra, Harini ; Pareeth, Sajid ; Ponti, Luigi ; Ricotta, Carlo ; Rizzoli, Annapaola ; Schaab, Gertrud ; Zebisch, Marc ; Zorer, Roberto ; Neteler, Markus (2015)

Understanding the causes and effects of species invasions is a priority in ecology and conservation biology. One of the crucial steps in evaluating the impact of invasive species is to map changes in their actual and potential distribution and relative abundance across a wide region over an appropriate time span. While direct and indirect remote sensing approaches have long been used to assess ...

Video and vision: videography of a Marian apparition

Knoblauch, Hubert ; Schnettler, Bernt (2015)

In this article, we sketch the field of qualitative video-analysis and locate videography within this. Instead of presenting the methods of videography formally, we illustrate the application of this method in a particular field: Marian apparitions occurring in a German town in 1999, captured live on video. The presentation of the method in this paper follows a general methodological structure....

On the other side of "agonism": "The enemy," the "outside," and the role of antagonism

Roskamm, Nikolai (2015)

This article takes issue with Chantal Mouffe's concept of agonistic pluralism. With this concept, Mouffe brings political theory to the field of real politics. In planning theory, the concept of agonism has recently been used as an alternative to the consensual communicative deliberative approach: The notion of agonism seems to be fit for replacing communicative theory as the theoretical framew...

A failed platform: the Citizen Consensus Conference travels to Chile

Ureta, Sebastián (2016)

This article starts by reviewing the setbacks that the recent Science and Technology Studies literature has identified in the functioning of technologies of democracy, the different arrangements that look to enact deliberation on technoscientific issues. Putting a focus on the Citizen Consensus Conference, it then proposes that several of these setbacks are related to the kind of "work" that th...

Innovating public participation methods: Technoscientization and reflexive engagement

Voß, Jan-Peter ; Amelung, Nina (2016)

We reconstruct the innovation journey of citizen panels', as a family of participation methods, over four decades and across different sites of development and application. A process of aggregation leads from local practices of designing participatory procedures like the citizens jury, planning cell, or consensus conference in the 1970s and 1980s, to the disembedding and proliferation of proced...

Die Schlinge - eine Schlaufenverankerung aus wechselseitig übereinandergeschlagenen Carbonfasern für Zugglieder aus carbonfaserverstärktem Kunststoff

Zwingmann, Bernd (2017)

Carbonfasern eignen sich aufgrund ihrer hohen Zugfestigkeit in Faserrichtung besonders für Zugglieder im Bauwesen. Dabei stellt die Verankerung der konzentrierten Kraft am Ende des Zugglieds eine große Herausforderung dar, da die Carbonfaser quer zur Faserrichtung nur eine geringe Festigkeit aufweist. In dieser Arbeit werden sogenannte Schlingen vorgestellt, mit denen die Carbonfasern eines Zug...

Impediments, incentives and interrelations with other objectives

Zimmer, Anne Karina (2017)

The Paris Agreement on climate change mitigation – celebrated as a historic breakthrough – relies on the voluntary implementation of adequate climate policy measures on the national and sub-national levels. The compliance with mitigation pledges will crucially depend on the interplay of different incentives and political realities in the emitting countries. It is therefore of fundamental import...

Untersuchungen zum denkmalverträglichen Feuchteschutz bei sommerlicher Kondensation in Kirchen

Schrimpf, Petra (2017)

Die Sommerkondensation wird als jahreszeitlich bedingtes Phänomen beschrieben, bei dem in den Frühjahrs- und Frühsommermonaten in Gebäuden mit einer hohen Wärmespeicherfähigkeit Kondensat an den Innenflächen der Umfassungsbauteile auftreten kann. Kirchen sind diesen Gebäuden zuzurechnen. Für das Auftreten von Sommerkondensation sind häufig nicht klimaangepasste Lüftungsvorgänge verantwortlich. ...
