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...

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...

Wichmann, Andreas (2018)

For several years, digital 3D city models have taken a central role in a number of different tasks. These models are used in urban and regional planning, surveying, and navigation and telecommunication technology. They also enable in the environmental field precise analyses and simulations of pollutant, flood, and noise propagation. For many applications, realistic building models are an essent...

Composition, properties, origin and evolutionary pathways of solid bitumens from SE Turkey

Hosseini Baghsangani, Seyed Hossein (2018)

The south-eastern region of Turkey is the most petroliferous region of the country and there are many surface and subsurface hydrocarbon occurrences. In particular, this region is noted for the widespread occurrence of solid bitumen veins and vugs, ostensibly generated from the same source but showing different physicochemical characteristics depending upon their geographic location. Although t...

Plant invasions in China: an emerging hot topic in invasion science

Liu, Jian ; Chen, Hua ; Kowarik, Ingo ; Zhang, Yiran ; Wang, Renqing (2012)

China has shown a rapid economic development in recent decades, and several drivers of this change are known to enhance biological invasions, a major cause of biodiversity loss. Here we review the current state of research on plant invasions in China by analyzing papers referenced in the ISI Web of Knowledge. Since 2001, the number of papers has increased exponentially, indicating that plant in...

The grass is always greener on the other side

Odparlik, Lisa Friederike ; Köppel, Johann ; Geißler, Gesa (2013)

Erfolgreiche Öffentlichkeitsbeteiligung braucht Information. Dennoch wird der Aspekt der adäquaten Informationsbereitstellung im Kontext der Umweltprüfungen in Deutschland noch wenig diskutiert. Aus demokratietheoretischer Sicht geht es dabei nicht nur um die Verfügbarkeit und leichte Auffindbarkeit von Dokumenten, Informationen und Verfahrensunterlagen. Auch Aspekte wie eine angemessene Bekann...

Leaching of inorganic and organic substances from construction materials and their ecotoxicological impact

Märkl, Veronika (2018)

In the last few years a growing environmental awareness in the field of construction materials can be observed. This has been, and continues to be, exacerbated since the Construction Products Regulations entered into force in 2013. In general construction products are in direct contact with the surrounding environment such as groundwater and soil. Especially grouting materials that often contai...

Die Interaktivität von Raum informeller Siedlungen

Wieck, Kathrin (2018)

Urbane Informalität ist ein deutlicher Ausdruck der Transformationsprozesse städtischer Räume unter globalen Urbanisierungsbedingungen. Sie stellt sich insbesondere in den Megastädten des globalen Südens als Überlebenskampf der sozial und ökonomisch Benachteiligten, aber auch als enge Verflochtenheit mit den urbanen Entwicklungsprozessen dar. Informelle Siedlungen sind von Armut, Unsicherheit u...
