Coralline demosponges ; a geobiological portrait
; ; Lange, Robert; Schumann-Kindel, Gabriela (Bulletin / The Tohoku University Museum, 2001)
The polyphyletic coralline demosponges possess a calcareous basal skeleton of 4 major morphotypes. Each has its own phylogenetic history, with different mechanisms of formation. One extant taxon of each skeletal type has ... -

Coralline Spongien - Der Versuch einer phylogenetisch-taxonomischen Analyse
(Selbstverlag Fachbereich Geowissenschaften, Freie Universität Berlin, 1992)
Porifera mit sekundären, kalkigen Skelettelementen werden, mit Ausnahme der Hexactinellida, in allen bekannten höheren Kategorien des Taxons Porifera beobachtet. Diese Gruppen werden als "Sclerospongia, coralline Spongien, ... -
„Corbicula-Schichten“ und „Inflata-Schichten” (Miozän, Mainzer Becken) - zur Begriffsklärung zweier unterschiedlicher stratigraphischer Einheiten
; (Mainzer geowissenschaftliche Mitteilungen; 24. 1995)
Der Begriff Corbicula-Schichten wurde von SANDBERGER (1863) für Sedimente des Mainzer Beckens eingeführt, die zwei verschiedene „Corbicula”-Arten (heute als Falsocorbicula faujasii und Polymesoda donacina bezeichnet) ... -
Core surface flow models from decadal and subdecadal secular variation of the main geomagnetic field
(GFZ, Helmholtz-Zentrum, 2005)The main objective of this thesis is an investigation and description of the secular variation of the Earth's magnetic field between 1980 and 2000. In particular, in the first part of this study the phenomenon of geomagnetic ... -

Corporate carbon performance data: Quo vadis?
; ; (Journal of Industrial Ecology, 2020)
Corporate carbon performance (CCP) has become a central topic in political, financial, and academic domains. At the same time, several characteristics of CCP data, including comparability and consistency, remain unresolved. ... -
Correcting Hargreaves‐Samani formula using geographical coordinates and rainfall over different timescales
; (Hydrological Processes, 2023-01-10)
The United Nations Food and Agricultural Organization (FAO) approved the Hargreaves‐Samani formula (HAR‐85) as an alternative to the standard Penman‐Monteith method (FAO‐PM) for estimating grass reference evapotranspiration ... -
Correlation Based Time Evolution of the Archeomagnetic Field
; ; ; (Journal of Geophysical Research: Solid Earth, 2021-07-16)
In a previous study, a new snapshot modeling concept for the archeomagnetic field was introduced (Mauerberger et al., 2020, https://doi.org/10.1093/gji/ggaa336). By assuming a Gaussian process for the geomagnetic potential, ... -
Correlation of magnetic fabric and crystallographic preferred orientations of naturally deformed carbonate — mica rocks from the Alpi Apuane in Italy and the Damara Orogen in Namibia
Otto, Michael; Hirt, Ann M.;; Schmidt, Volkmar; (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
The anisotropy of magnetic susceptibility (AMS) is a time-efficient method to describe crystallographic preferred orientations of rocks and has been applied in a wide field of sedimentary, metamorphic and magmatic geology. ... -
Correlation of Pleistocene sediments from boreholes in the Ludwigshafen area, western Heidelberg Basin
(E&G – Quaternary Science Journal; Vol.57, No. 3-4)Im Raum Ludwigshafen wurden mehrere Kernbohrungen sedimentologisch, palynologisch, paläomagnetisch, gesteinsmagnetisch und schwermineralogisch untersucht. Erste Ergebnisse der neuen Bohrung Ludwigshafen-Parkinsel P35 werden ... -

Cosmic rays and the magnetic field in the nearby starburst galaxy NGC 253
(Univ. Bochum, 2008)Beim Ras-RasGAP-Komplex ist die Hydrolyse des Guanosintriphosphats stark beschleunigt im Vergleich zu Ras allein. Dies wird hauptsächlich durch den Argininfinger R789 verursacht, der direkt zur Triphosphatgruppe zeigt. ... -
Cosmological backreaction - from the local Hubble expansion rate to dark energy
(Univ. Bielefeld, 2008)Despite the glorious successes of modern cosmology, our understanding of the cosmic substitution is still limited to a tiny fraction (a few per cents only). Accelerated expansion of the Universe, caused by the mysterious ... -
Cosmological solutions of the Einstein-Vlasov-scalar field system
(Univ. Berlin, 2005)The aim of this thesis is to obtain as much information as possible, about global solutions of the Cauchy problem for the Einstein-Vlasov-scalar field system with spherical, plane and hyberbolic symmetries written in areal ... -
Cosmology through gravitational lenses
(Univ. Potsdam, 2004)In dieser Dissertation nutze ich den Gravitationslinseneffekt, um eine Reihe von kosmologischen Fragen zu untersuchen. Der Laufzeitunterschied des Gravitationslinsensystems HE1104-1805 wurde mit unterschiedlichen Methoden ... -
Cost–benefit analysis of flood-zoning policies: A review of current practice
; (Wiley Interdisciplinary Reviews: Water, 2019)
One commonly proposed method to limit flood risk is land-use or zoning policies which regulates construction in high-risk areas, in order to reduce economic exposure and its vulnerability to flood events. Although such ... -
Could oxalate-extractable phosphorus replace phosphorus fractionation schemes in soil phosphorus prospections?—A case study in the prehistoric Milseburg hillfort (Germany)
; ; ; (Geoarchaeology, 2019)
A geoarchaeological soil phosphorus (P) prospection is used to identify a gate within the prehistoric rampart of the Milseburg hillfort (Hesse, Germany). This study compares the application of a P fractionation scheme and ...
