Converting forests into rubber plantations weakened the soil CH4 sink in tropical uplands
(Land Degradation & Development, 2019)Large-scale conversion of natural forest to rubber plantations has taken place for decades in Southeast Asia, help to make it a deforestation hot spot. Besides negative changes in biodiversity, ecosystem water, and carbon ... -
Cooling rates of pyroclastic deposits inferred from mineral magnetic investigations: a case study from the Pleistocene Mýtina Maar (Czech Republic)
(International Journal of Earth Sciences, 2020-05-13)Tephra layers of the Mýtina Maar, Czech Republic, contain ferrimagnetic Mg–Al-rich titanomagnetite, which is suggested to originate from a fractionated alkaline CO2-rich lithospheric mantle melt. We investigated the magnetic ... -
Cophasing LINC-NIRVANA and molecular gas in low-luminosity QSO host and cluster galaxies
(Univ. Köln, 2007)This thesis consists of two parts. The first part reports on the development of a fringe tracking system for LINC-NIRVANA, the near-infrared homothetic imaging camera for the Large Binocular Telescope (LBT). LINC-NIRVANA ... -

Coralline demosponges ; a geobiological portrait
(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
(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
