The role of efficient technology for achieving climate change mitigation and development

Ward, Hauke (2018)

This thesis is motivated by a potential conflict within the sustainable development goals, which refers to climate change mitigation and development. This conflict is of special relevance for developing countries. On the one hand these are projected to be most severely impacted by climate change. On the other hand fast economic development, connected to emitting greenhouse gases, could help sub...

Dissolved organic matter in differently managed forest ecosystems

Thieme, Lisa (2018)

Dissolved organic matter (DOM) represents one of the most dynamic fractions of organic matter. It plays an important role in the biogeochemical cycles of carbon and nutrients, which in turn is strongly affected by its chemical quality. This thesis aims to improve the understanding of DOM quality and its changes along the water flow path through forested Mid-European ecosystems, as they are infl...

In the second column the pairs of legally and illegally parked cars are counted. In the third column and fifth column brand and model of each car are coded. The fourth column shows the values of a car brand s...

Microbial population composition of ochrous biofilms and water samples obtained from technical groundwater-fed systems

Schröder, Josephin (2018)

This study assessed the abundance, composition, diversity and functional organisation of bacterial communities correlated to chemical water parameters in four technical groundwater-fed systems. Each sampling site was vulnerable to iron-clogging and was characterised by its own specific technical and hydrochemical conditions. Biofilm and groundwater samples were obtained and compared for drinkin...

WHWP - Walter Höllerer bei WikiPedia

Bronner, Friedrich Georg (2018)

The dissertation thesis "WHWP - Walter Höllerer bei WikiPedia" documents research about the german WikiPedia-Artikel on Walter Höllerer. The article „Walter Höllerer“ was created in 2003 and the article was researched throughout 2015: the thesis shows the development of WHWP over the time of twelve years. There were 113 changes made to the article by 89 very diverse authors. This specific artic...

Influence of Poroelasticity on the 3D Seismic Response of Complex Geological Media

Wuttke, Frank ; Dineva, Petia ; Fontara, Ioanna-Kleoniki (2017)

Elastic wave propagation in 3D poroelastic geological media with localized heterogeneities, such as an elastic inclusion and a canyon is investigated to visualize the modification of local site responses under consideration of water saturated geomaterial. The extended computational environment herein developed is a direct Boundary Integral Equation Method (BIEM), based on the frequency-dependen...

Price anchoring in Online Markets: an Empirical Assessment

Bogliacino, Francesco ; Cuntz, Alexander (2013)

There is a large literature in behavioral economics contradicting the empirical prediction of rational choice theory once applied to auctions. The issue is of particular relevance due to the large use of auctions in mechanism design. One of the heuristics that may induce biased behavior is anchoring, namely the possibility that uninformative information influences choices. In this article we as...

Copper precipitation as consequence of steel corrosion in a flow-through experiment mimicking a geothermal production well

Regenspurg, Simona ; Geigenmüller, Ives ; Milsch, Harald ; Kühn, Michael (2017)

Decreasing production rates and massive precipitation of native copper (Cu(0)) were observed in the production well at the geothermal research facility Groß Schönebeck (Germany). The Cu precipitates filling up the well are a product of an electrochemical corrosion reaction between dissolved copper (Cu2+, Cu+) in the brine and iron (Fe(0)) of the carbon steel liner. It was hypothesized that this...

Draft Genome Sequence of a Potential Nitrate-Dependent Fe(II)-Oxidizing Bacterium, Aquabacterium parvum B6

Zhang, Xiaoxin ; Ma, Fang ; Szewzyk, Ulrich (2016)

Aquabacterium parvum B6 is a potential nitrate-dependent Fe(II)-oxidizing bacterium. The genes related to its denitrifying mechanism and iron metabolisms were unknown. We present the draft genome of Aquabacterium parvum B6, which could provide further insight into the nitrate-dependent Fe(II)-oxidizing mechanism of strain B6.

Complete Genome Sequence of “Candidatus Viadribacter manganicus” Isolated from a German Floodplain Area

Braun, Burga ; Szewzyk, Ulrich (2016)

Iron- and manganese-depositing bacteria occur in many soils and all water systems, and their biogenic depositions of ochre in technical systems may cause severe clogging problems and monetary losses. “Candidatus Viadribacter manganicus” is a small coccoid, iron- and manganese-depositing bacterium isolated from the Lower Oder Valley National Park, Germany.

Draft Genome Sequence of Rheinheimera sp. Strain SA_1 Isolated from Iron Backwash Sludge in Germany

Schröder, Josephin ; Braun, Burga ; Liere, Karsten ; Szewzyk, Ulrich (2016)

Rheinheimera sp. strain SA_1 is an iron-depositing bacterium for which we report a draft genome sequence. Strain SA_1 was isolated from iron backwash sludge of a waterworks in Germany. The Illumina MiSeq technique was used to sequence the genome of the strain.

Draft Genome Sequence of Ideonella sp. Strain A 288, Isolated from an Iron-Precipitating Biofilm

Braun, Burga ; Künzel, Sven ; Szewzyk, Ulrich (2017)

Here, we report the draft genome sequence of the betaproteobacterium Ideonella sp. strain A_228. This isolate, obtained from a bog iron ore-containing floodplain area in Germany, provides valuable information about the genetic diversity of neutrophilic iron-depositing bacteria. The Illumina NextSeq technique was used to sequence the draft genome sequence of the strain.

Draft Genome Sequence of the Gram-Positive Neutrophilic Iron-Precipitating Kineosporia sp. Strain A_224

Braun, Burga ; Künzel, Sven ; Szewzyk, Ulrich (2017)

We report here the draft genome sequence of the neutrophilic iron-precipitating Kineosporia sp. strain A_224. Analysis of the predicted genes may improve our knowledge of its role in ochrous formations in natural and technical water systems. This is the first public genome sequence of a Kineosporia aurantiaca strain.

Schuster, Anna-Kathrin ; Szewzyk, Ulrich (2016)

Rheinheimera sp. strain F8 is a biofilm-forming gammaproteobacterium that has been found to produce large amounts of filamentous extracellular DNA. Here, we announce the de novo assembly of its genome. It is estimated to be 4,464,511 bp in length, with 3,970 protein-coding sequences and 92 RNA-coding sequences.

Machine learning of accurate energy-conserving molecular force fields

Chmiela, Stefan ; Tkatchenko, Alexandre ; Sauceda, Huziel E. ; Poltavsky, Igor ; Schütt, Kristof T. ; Müller, Klaus-Robert (2017)

Using conservation of energy - a fundamental property of closed classical and quantum mechanical systems - we develop an efficient gradient-domain machine learning (GDML) approach to construct accurate molecular force fields using a restricted number of samples from ab initio molecular dynamics (AIMD) trajectories. The GDML implementation is able to reproduce global potential energy surfaces of...

The impact of high-end climate change on agricultural welfare

Stevanović, Miodrag ; Popp, A. ; Lotze-Campen, H. ; Dietrich, J. P. ; Müller, C. ; Bonsch, Markus ; Schmitz, C. ; Bodirsky, B. L. ; Humpenöder, Florian ; Weindl, I. (2016)

Climate change threatens agricultural productivity worldwide, resulting in higher food prices. Associated economic gains and losses differ not only by region but also between producers and consumers and are affected by market dynamics. On the basis of an impact modeling chain, starting with 19 different climate projections that drive plant biophysical process simulations and ending with agro-ec...
