Pseudo-total antimony content in topsoils of the Berlin Metropolitan Area
;
(Journal of Soils and Sediments, 2020-08-04)
Purpose: Sb is a metalloid that naturally occurs in traces in the Northern German Lowland Area, only. Its frequent and still growing demand for industrial purposes and its release during coal combustion and by ... -
Ptychographic X-ray speckle tracking
(Journal of Applied Crystallography, 2020)A method is presented for the measurement of the phase gradient of a wavefront by tracking the relative motion of speckles in projection holograms as a sample is scanned across the wavefront. By removing the need to obtain ... -

Pupilla loessica LOŽEK 1954 (Gastropoda: Pulmonata: Pupillidae) - „A living Fossil“ in Central Asia?
; Hoffmann, Matthias H. (E&G – Quaternary Science Journal; Vol.58, No. 1)
LOŽEK (1986) vertritt die Ansicht, dass Pupilla loessica rezent in Zentralasien vorkommt. Die vorliegende Studie hat das Ziel zu diesem Thema erste konkrete Diskussionsbeiträge zu liefern. Zu verstehen ist diese Arbeit als ... -
Pure cross-anisotropy for geotechnical elastic potentials
(Acta Geotechnica, 2021-07-28)The pure cross-anisotropy is understood as a special scaling of strain (or stress). The scaled tensor is used as an argument in the elastic stiffness (or compliance). Such anisotropy can be overlaid on the top of any elastic ... -
Qualitative und quantitative petrographische Untersuchungen der Kohlen aus den flözführenden Schichten der Antioquia-Formation/Kolumbien
(1980)Es wurde eine geologische Obersicht der Amaga-Mulde aufgestellt, wobei die kohlenführende Antioquia-Formation besonders behandelt wurde. Die Ergebnisse wurden in einer geologischen und einer tektonischen Karte sowie in ... -
Qualitätsanforderungen des Erwerbsgartenbaues an Kultursubstrate - Einfluß der Gewinnungsverfahren auf die Eigenschaften der Torfe
(TELMA - Berichte der Deutschen Gesellschaft für Moor- und Torfkunde; Band 23; 1993)Der Erwerbsgärtner verlangt heute Substrate mit hoher Kultursicherheit. Dabei müssen die Kultursubstrate unter allen Anbaubedingungen zum Erfolg führen. Der Hochmoortorf erfüllt als Substratgrundlage diese Bedingungen in ... -
Quality assessment of replacement stones for the Cologne Cathedral: mineralogical and petrophysical requirements
(Environmental Earth Sciences, 2011)Owing to its long building history, different types of building stones comprised the construction of the Cologne Cathedral. Severe damage is observed on the different stones, e.g., sandstones, carbonate, and volcanic rocks, ... -
Quantification and analysis of surface macroplastic contamination on arable areas
; (Journal of Soils and Sediments, 2021-12-03)
Purpose: The present study provides quantitative data on the degree of macroplastic contamination of two conventionally treated arable areas in North Rhine-Westphalia (Germany), which differ only in the use of ... -
Quantification and sensitivity of fault seal parameters demonstrated in an integrated reservoir modelling work flow. A case study on the Njord Field, Halten Terrace, Norway
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The primary objective of this paper is to present a fault seal case study from the Njord Field, offshore Norway. The study utilised analogue field studies as well as core descriptions and petrophysical well data in order ... -
Quantification of Evaporation and Drainage Processes in Unsaturated Porous Media Using Magnetic Resonance Imaging
; Hille‐Reichel, Andrea; Zehe, Erwin; ; (Water Resources Research, 2020-03-01)
The water loss in packed beds was studied spatially and time‐resolved via magnetic resonance imaging on the pore scale. The packed beds were measured under water‐saturated and unsaturated conditions, while the magnetic ... -
Quantification of Fracture Roughness by Change Probabilities and Hurst Exponents
; ; ; ; (Mathematical Geosciences, 2021-12-17)
The objective of the current study is to utilize an innovative method called “change probabilities” for describing fracture roughness. In order to detect and visualize anisotropy of rock joint surfaces, the roughness of ... -
Quantification of Hyporheic Nitrate Removal at the Reach Scale: Exposure Times Versus Residence Times
; ; ; ; (Water Resources Research, 2019)
The rate of biogeochemical processing associated with natural degradation and transformation processes in the hyporheic zone (HZ) is one of the largest uncertainties in predicting nutrient fluxes. We present a lumped ... -
Quantification of Impact‐Induced Melt Production in Numerical Modeling Revisited
; ; (Journal of Geophysical Research: Planets, 2022-11-29)
Melting and vaporization of rocks in impact cratering is mostly attributed to be a consequence of shock compression. However, other mechanism such as plastic work and decompression by structural uplift also contribute to ... -
Quantification of submarine degassing of Panarea Vol. ano in the Aeolian archipelago, Italy
(Freiberg Online Geosciences; Vol. 23.2009) -
Quantifizierung lokaler Grundwassereintritte in die Spree und deren Bedeutung für die Verockerungsproblematik in der Laustiz
; ; (Grundwasser, 2020-05-23)
Eine unbekannte, schwer zu bestimmende aber zentrale Komponente in der Verockerungs-Problematik der Spree ist der lokale Grundwasserzufluss. Als Teil dieser Studie wurden mithilfe des natürlichen Tracers Radon (222Rn) die ... -
Quantifying Convective Aggregation Using the Tropical Moist Margin's Length
; ; (Journal of Advances in Modeling Earth Systems, 2020)
On small scales, the tropical atmosphere tends to be either moist or very dry. This defines two states that, on large scales, are separated by a sharp margin, well identified by the antimode of the bimodal tropical column ... -
Quantifying electron cascade size in various irradiated materials for free‐electron laser applications
(Journal of Synchrotron Radiation, 2022-02-15)Studying electron‐ and X‐ray‐induced electron cascades in solids is essential for various research areas at free‐electron laser facilities, such as X‐ray ...
