Real-time and in situ hyperspectral Raman imaging of high-temperature solid-solid reactions in silicate ceramics
(2022-07-05)
Raman spectroscopy has become one of the most important analytical tools for a wide range of research areas in all sub-disciplines of physics, chemistry, biology and medicine. In the beginning the applications were limited ......
New aspects of deglaciation in southern Norway: Climate variability derived from surface exposure ages of Late Quaternary and Holocene landforms
(2020-01-30)
The investigation of periglacial and related landforms in South Norway is of high interest for exploring timings of deglaciation and to assess their geomorphological connectivity to palaeoclimatic changes during the Late ...
Spaceborne SAR Remote Sensing for Monitoring of Vegetation Dynamics in Arid and Semi-arid Environment
(2020-04-22)
Drylands are under constant threat from multiple stresses and challenges, which occur as a result of a complex interaction of natural processes, and human-induced processes caused by unsustainable land use practices, leading ...
Die Implementierung des Themas Fernerkundung in den Schulunterricht der Sekundarstufe I durch das neue MINT-Wahlpflichtfach "Geographie-Physik": eine Studie zur praktischen Schulfachgestaltung im Differenzierungsbereich der Jahrgangsstufen 8 und 9 an Gymnasien in Nordrhein-Westfalen am Beispiel des Gymnasiums Siegburg Alleestraße
(2021-10-26)
Schülerinnen und Schüler werden in ihrer Alltagswelt seit dem letzten Jahrzehnt immer früher mit Satellitenbildern konfrontiert. Durch den Wetterbericht und die Nachrichtensendung im Fernsehen oder durch virtuelle Globen ...
Climate field reconstructions from pollen and macrofossil syntheses using Bayesian hierarchical models
(2020-01-09)
Studying past climate states is important to understand climate changes and climate variability on centennial to orbital timescales, to analyze the reaction of the Earth system to large-scale changes in external forcings, ...
Vorkommen Antibiotika-resistenter Bakterien in der aquatischen Umwelt: Zusammenhänge zu dem Vorkommen antibiotisch wirkender Substanzen
(2022-01-05)
Ein Anstieg der Resistenzen bei gleichzeitiger Stagnation hinsichtlich der Ent-wicklung neuer Antibiotika ist vor allem für Infektionen mit Gram-negativen Bakte-rien kritisch. Die WHO spezifizierte bereits 2014 ...
Sequential and coupled inversion of time-lapse borehole GPR measurements for vadose zone model parameterization
(2022-01-31)
A profound understanding of the infiltration dynamics into the vadose zone is crucial to our capacity to link surface and subsurface processes for the description of the hydrologic cycle. A key to establish reliable models ...
Applying Disaster Risk Governance in Dynamic Environments: Case study Rio de Janeiro State, Brazil
(2021-05-17)
Between 1980 and 2015, around 1.6 billion people were killed in meteorological, geophysical, hydrological or climatological disasters. Future annual losses are estimated to reach US4 billion in the built environment alone. ...
Mining and small-scale farming in the Andes: Socio-environmental roots of land-use conflict
(2020-04-08)
The Peruvian Andes are one of the most important water sources for the country. Therefore, their exploitation might pose critical threats for local farming activities, national economy, and water quantity and quality. At ...
Impact assessment of global change on wetland-catchment interactions in a tropical East African catchment
(2020-02-27)
Water is the key to sustainable development, especially in sub-Saharan Africa (SSA), where a large part of the population lives on subsistence farming. Reliable knowledge of available water resources therefore is an ...
