Über mathematische Objekte der Geologie
(, 2020) -
Konsequenzen des natürlich geschlossenen Systems der Geologie (II) - Über Proportionalität in der Geologie
(, 2020)Die Relativierung des mathematischen Begriffs der direkten Proportionalität führt in der Geologie zur Darstellung der geometrischen und der arithmetischen Relation und zur Begründung des geologischen Binärsystems. Die ... -
Das natürlich geschlossene System - Grundlage einer theoretischen Geologie? - Über geologische Reflexionen von Friedrich Engels im Anti - Dühring
(, 2019)Das duale System proportionaler Zusammenhäng des natürlich geschlossenen Systems ( geologisches Binärsystem) ist mit der philosophisch begründeten Logik ( materialistische Dialektik) in perfekter Übereinstimmung. Somit ... -
Geologische Exkursion Südost-Schweden - Schonen, Blekinge, Öland, Region Västervik
(Universitätsverlag Göttingen, Göttingen, 2019)Das breite inhaltliche Spektrum der vorgestellten Region auf dem Kraton Baltica (Präkambrisches Grundgebirge, Deckgebirge, Deformationszonen, Quartärgeologie) eignet sich sehr gut für eine allgemeingeologische Exkursion ... -
Das natürlich geschlossene System - Grundlage einer theoretischen Geologie? - Eine Darstellung der inneren Logik des NGS
(, 2019)Es werden grundsätzliche Fragestellungen einer mathematisch bzw. axiomatisch begründeten Geologie dargestellt. -
Land Surface Temperature Variation Due to Changes in Elevation in Northwest Vietnam
(Climate, 2018)Land surface temperature (LST) is one of the most important variables for applications relating to the physics of land surface processes. LST rapidly changes in both space and time, and knowledge of LST and its spatiotemporal ... -
Snowmobile impacts on snowpack physical and mechanical properties
(The Cryosphere, 2018)Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different ... -
The Suitability of Pozzolan as Admixing Aggregate for Fe0-Based Filters
(Water, 2018)Continuous gravity-fed column experiments using the methylene blue (MB) discoloration method were performed to characterize the suitability of a pozzolan (PZ) specimen as alternative admixing aggregate for metallic iron ... -
Climate effects on vegetation vitality at the treeline of boreal forests of Mongolia
(Biogeosciences, 2018)In northern Mongolia, at the southern boundary of the Siberian boreal forest belt, the distribution of steppe and forest is generally linked to climate and topography, making this region highly sensitive to climate change ... -
Ideas and perspectives: hydrothermally driven redistribution and sequestration of early Archaean biomass – the “hydrothermal pump hypothesis”
(Biogeosciences, 2018)Archaean hydrothermal chert veins commonly contain abundant organic carbon of uncertain origin (abiotic vs. biotic). In this study, we analysed kerogen contained in a hydrothermal chert vein from the ca. 3.5 Ga ... -
A fossil species of the enigmatic early polypod fern genus Cystodium (Cystodiaceae) in Cretaceous amber from Myanmar.
(Scientific reports, 2017-11-06)The monospecific fern genus Cystodium (Cystodiaceae; Polypodiales) occurs exclusively in the tropical forests of the Malay Archipelago, the Admiralty Islands, the Louisiade Archipelago, and the Solomon Islands. Divergence ... -
Fast methane diffusion at the interface of two clathrate structures.
(Nature communications, 2017-10-20)Methane hydrates naturally form on Earth and in the interiors of some icy bodies of the Universe, and are also expected to play a paramount role in future energy and environmental technologies. Here we report experimental ... -
Tracing the oxygen isotope composition of the upper Earth's atmosphere using cosmic spherules
(Nature communications, 2017-06-01)Molten I-type cosmic spherules formed by heating, oxidation and melting of extraterrestrial Fe,Ni metal alloys. The entire oxygen in these spherules sources from the atmosphere. Therefore, I-type cosmic spherules are ... -
Making Fe0-Based Filters a Universal Solution for Safe Drinking Water Provision
(Sustainability, 2017)Metallic iron (Fe0)-based filtration systems have the potential to significantly contribute to the achievement of the United Nations (UN) Sustainable Development Goals (SDGs) of substantially improving the human condition ... -
Sustainability impact assessment of peatland-use scenarios: Confronting land use supply with demand
(Ecosystem Services, 2017)Sustainable development of land use is determined by changes of the regional supply of Land Use Functions (LUFs) and the demand of future societal land use claims. LUFs are based on the ecosystem services concept, but ... -
Diversity and composition of herbaceous angiosperms along gradients of elevation and forest-use intensity.
(PloS one, 2017)Terrestrial herbs are important elements of tropical forests; however, there is a lack of research on their diversity patterns and how they respond to different intensities of forest-use. The aim of this study was to analyze ... -
Comparison of Random Forest, k-Nearest Neighbor, and Support Vector Machine Classifiers for Land Cover Classification Using Sentinel-2 Imagery.
(Sensors (Basel, Switzerland), 2017)In previous classification studies, three non-parametric classifiers, Random Forest (RF), k-Nearest Neighbor (kNN), and Support Vector Machine (SVM), were reported as the foremost classifiers at producing high accuracies. ... -
Zhamanshin astrobleme provides evidence for carbonaceous chondrite and post-impact exchange between ejecta and Earth’s atmosphere
(Nature Communications, 2017)Chemical fingerprints of impacts are usually compromised by extreme conditions in the impact plume, and the contribution of projectile matter to impactites does not often exceed a fraction of per cent. Here we use chromium ... -
A Burmese amber fossil of Radula (Porellales, Jungermanniopsida) provides insights into the Cretaceous evolution of epiphytic lineages of leafy liverworts
(Fossil Record, 2017)DNA-based divergence time estimates suggested major changes in the composition of epiphyte lineages of liverworts during the Cretaceous; however, evidence from the fossil record is scarce. We present the first Cretaceous ...
