Technical requirements in public auctions to make solar plants shine

Adela Marian, Florian Anselm Münch, Elena Ammel, Niels Ferdinand, Saurabh Kumar, Asier Ukar, Maialen López, Knut Blind & Rainer Quitzow
The deployment of solar photovoltaic (PV) technology is accelerating across the globe, as prices continue to fall and countries begin their transition from fossil to renewable energy. Public auctions have become the dominant policy tool for solar PV deployment: 106 countries held renewable energy auctions (dominated by solar) by the end of 2018 (IRENA a, 2019). One third of the 55 countries that held renewable auctions in 2017 – 2018 did so for the first time (ibid.)....

Die unterschiedliche Ausbreitungsdynamik wurde anhand der Ableitungsdiagramme der zeitlichen Entwicklung der Tupel [x(t),x'(t)] der wöchentlichen Inzidenzraten und ihrer Ableitungen analysiert. Die Wirksamkeit der verschiedenen Lockdown-Maßnahmen in Deutschland während der zweiten Welle wird anhand der Differenz der...

How minerals govern the advance of weathering: comparison of a shallow and a deep weathering profile in different climatic zones (Chilean Coastal Cordillera)

Ferdinand Jakob Hampl , Ferry Schiperski , Nicole Stroncik , Michael Facklam , Friedhelm von Blanckenburg & Thomas Neumann
Weathering is the fundamental precondition for erosion and soil formation which sculpture Earth´s surface. It is a complex interplay of minerals, rock fabric, tectonical fractures, climate, and organic activity. To explore the dependences between these factors two weathering profiles on magmatic bedrock were compared using six-meter-deep soil pits and drill cores in both a humid and a Mediterranean climate regime of Chile. Detailed mineralogical and geochemical investigations of soil and saprolite were combined with spatially...

Carbonatites and alkaline rocks

Michael A.W. Marks , Benjamin F. Walter & R. Johannes Giebel
This session thematizes the formation, evolution and economic importance of carbonatites and alkaline rocks. These play an important role for our society, as they contain exceptional high levels of critical raw materials, such as REE, Nb, P and F, to name a few. However, to understand how such deposits form, we need to understand how their rocks and mineral assemblages formed in space and time. Although our knowledge about the formation and mineralization as well...

The Middle Buddha Hall of Chongming Monastery in Gaoping County, Shanxi Province is an existing wooden construction from the early period of the Northern Song Dynasty, and predates the treatise on architecture Yingzao Fashi. Its unusual main components of the dougong and the roof construction are a continuation of the style from the Tang Dynasty, which provides valuable examples for the study of the development of wooden structure in China. In the summer of 2018,...

ON BUCKLING INDUCED BY A CHEMICAL REACTION

V.O. Shtegman, A.V. Morozov Morozov, A.B. Freidin & W.H. Müller
This study is concerned with the modeling of plate buckling induced by a chemical reaction and is inspired by the observation that buckling may be a mechanism of stress relaxation in Si-based anodes in Li-ion batteries. A chemical reaction is localized at a sharp interface and accompanied by transformation strains, which produce internal stresses. If external supports restrict the deformation of the plate, buckling may occur. At the same time, mechanical stresses affect the kinetics...

A global review of carbonatite-hosted fluid inclusions and the role of fluid release on carbonatite magma ascent

Benjamin Florian Walter , Johannes Giebel , Matthew Steele-MacInnis , Michael Marks , Jochen Kolb & Gregor Markl
Carbonatites crystallize from mantle-derived carbonate- and volatile-rich melts that exsolve large amounts of fluids during their ascent through and emplacement into the crust. A global review of available fluid inclusion data for carbonatitic systems from variable emplacement depths identified four types of fluid inclusions: (type-I) vapour-poor H2O-NaCl fluids with <50 wt.% salinity; (type-II) vapour-rich H2O-NaCl-CO2 fluids with <5 wt.% salinity; (type-III) multi-component fluids with high salinity without CO2; and (type-IV) multi-component fluids with high salinity...

„Aggressiver Humanismus“ : Politischer Widerstand im 21. Jahrhundert

Nora Rigamonti
In this article I examine public engagement with matters of concern by affects drawing on anethnographic case study on the Center for Political Beauty’s antagonistic artwork and practices ofpolitical resistance against human rights violations. Focusing particularly on the affective attachmentsbetween human and non-human elements, as recent work in Science and Technology Studies andActor-Network Theory has emphasized, I identify and discuss specific productivities and problematicsof these complex entanglements. My analysis indicates that these co-constitutive interactions betweenheterogeneous...

Manfred Renger, Jan Bug, Sabine Heumann & Udo Müller
Die Entnahme von Grundwasser kann sich auf den Bodenwasserhaushalt und damit auch auf den landwirtschaftlichen Ertrag auswirken. Eventuelle negative Wirkungen auf landwirtschaftliche Erträge sind finanziell angemessen auszugleichen. Die hier beschriebene Auswertungsmethode dient zur Ermittlung der Auswirkungen von Grundwasserabsenkungen auf den Ertrag landwirtschaftlich genutzter Flächen (Acker und Grünland). Sie kann in bodenkundlichen Gutachten zum Wasserrechtsantrag und in Jahresberichten zur Beweissicherung angewendet werden. Hier werden das allgemeine Methodenprinzip sowie das schrittweise Vorgehen für den Vergleich ohne bzw....

Tectonic and environmental perturbations at the Permian-Triassic boundary: insights from the Blue Nile River Basin in central Ethiopia

Maryam Mansouri , Matthias Hinderer , Laura Stutenbecker , Guido Meinhold , Enkurie L. Dawit , Jasper Berndt & Robert Bussert
The Blue Nile River Basin contains a thick fluvio-lacustrine sediment succession of Permian to Jurassic age. Its evolution is linked to extensional tectonics during break-up of Pangea in the aftermath of the Carboniferous-Permian glaciation. We collected sandstone samples from several sections in order to study the tectonic evolution and possible impacts of environmental perturbation around the Permian-Triassic boundary. Based on thin-section petrography, bulk-rock geochemistry, heavy mineral spectra, and detrital zircon U-Pb ages we are able...

Background analysis and details of evolutionary simulations from Social interaction can select for reduced ability

John M. McNamara & Max Wolf
Animals, including humans, differ in a wide range of physical and cognitive abilities ranging from measures of running speed and physical strength to learning ability and intelligence. We consider the evolution of ability when individuals interact pairwise over their contribution to a common good. In this interaction, the contribution of each is assumed to be the best given their own ability and the contribution of their partner. Since there is a tendency for individuals to...

Groundwater quality: new developments on understanding transport and mobility of contaminants related to anthropogenic impacts.

Tobias Licha & Ferry Schiperski
Groundwater quality is widely compromised by anthropogenic impact. This becomes evident by the presence of numerous anthropogenic organic and inorganic contaminants in groundwater. Contaminants are of widespread origin. They enter the groundwater associated to different processes such as sewer failure, agricultural activities or contaminated industrial sites. Understanding the input mechanism, transport, attenuation and degradation processes in short and long term is crucial for sustainable groundwater development. Although unwanted, contaminants even in smallest quantities might provide...
