Observations, analysis and interpretation with non-LTE of chromospheric structures on the Sun
(2008-05-27)The Sun possesses a complex layer called chromosphere, which extends above the overwhelmingly bright photosphere. With decreasing density, the solar magnetic fields start here to dominate the dynamics, giving rise to new ... -
On the possibility of using organic molecules in the characterization of subsurface processes
(2013-05-15)Nowadays, tracer tests represent an important part in the repertoire of hydro(geo)logical characterization techniques. For determining hydromechanical parameters of and flow properties within a reservoir or an aquifer, ... -
On the significance and predictability of geological parameters in the exploration for geothermal energy
(2018-05-02)Sufficient reservoir permeability is essential to exploit heat resources for geothermal energy. Reliable prediction of permeability and in consequence flow rate in a deep geothermal reservoir is difficult to predict because ... -
Optimierung der Eigenschaften von neuartigem Elektrobandstahl
(2023-05-23)In the present work, the influence of silicon (Si) and particularly aluminium (Al) on the properties of electrical steel is studied. The aim is to decrease magnetization losses and therefore increase the efficiency of ... -
Optimierung der Exploration, Gewinnung und Materialcharakterisierung von Naturwerksteinen
(2009-04-01)Since antiquity dimension stones have represented the embodiment of values like preciousness and longevity. The last several decades were characterised by a continuous growth in the use of ... -
Organische Petrologie und Mikrofazies der mitteleozänen Seesedimente des Eckfelder Maares (Südwesteifel)
(2003-02-28)The present thesis documents and discusses the results of the project "Organic petrology and microfacies of the Middle Eocene lacustrine sediments from the Eckfeld Maar (Southwest Eifel)" ... -
Organische Spurenstoffe als Indikatoren zur Charakterisierung komplexer Grundwassersysteme
(2015-02-10)Conventional hydrogeological methods (e.g. water level contour maps, hydrographs, pumping tests) can only provide limited information for the basic characterization of complex aquifers, namley catchment delineation, deriving ... -
Origin and evolution of ureilite vein metal - Fe, Ni, Co and Ni-isotope systematics of ureilite vein metal and ureilite silicates
(2010-01-28)Ureilites are meteorites which show characteristics of primitive and differentiated meteorites. They are mainly composed of olivine and pyroxene. The pyroxene is in most cases pigeonite. ... -
Outcrop analogue studies of rocks from the Northwest German Basin for geothermal exploration and exploitation
(2014-10-09)Rock heterogeneities in terms of layering and fault zones are common phenomena in sedimentary basins such as the Northwest German Basin (NWGB). At geothermal projects, these heterogeneous rock properties affect many issues ... -
Oxygen isotope microanalysis of silicates with application to fluid-rock interfaces
(2001-10-31)In order to investigate crustal fluid-rock interactions an oxygen isotope microprobe was set up. Oygen is extracted from silicates by Ultra-Violet (UV)-laser fluorination and its isotropic ... -
Paläoökologische Interaktionen von Organismen aus Baltischem und Bitterfelder Bernstein
(2020-11-06)Because of the quick fixation and detailed conservation of millions-of-years-old arthropods, other small animals and plant parts, amber is very suitable for the conservation of ancient behaviours and interactions. In this ... -
Paläoökologische und geochemische Studien auf Schwamm-Mikroinkrustrierer- Gemeinschaften ausgewählter Cipit Kalke aus der St. Cassian Formation (Unterkarn, Obertrias) von der Dolomiten, Nordostitalien
(2010-12-23)The Lower Carnian St. Cassian Formation (Dolomites, NE Italy) is well known for its very diverse and exceptionally well-preserved fauna. It dates from Middle to Late Triassic and comprises ... -
Paläoproterozoisches Krustenwachstum (2.0-1.8 Ga) am Beispiel der Västervik-Region in SE-Schweden und dem Kamanjab Inlier in NW-Namibia
(2013-02-04)Whole rock geochemical analyses using major and trace elements in combination with the Sm-Nd, Rb-Sr, K-Ar and U-Pb isotope systems as well as studies of P-T conditions on metamorphic rocks from the Västervik-area (SE-Sweden), ... -
Partizipation in Umweltorganisationen
(2013-03-05)The thesis is about participation in environmental organisations. The Deutscher Jugendbund für Naturbeobachtung (DJN) and Greenpeace in Göttingen have been examined regarding to similarities and differences in the way ... -
Perspectives of Sustainable Collaborative Management: A Case Study in Kerinci Seblat National Park, Sumatra-Indonesia
(2017-05-02)A conservation area is a natural resource in which management uses the resources based on the principles of protecting and preserving by utilizing wisely and minimizing inflicted damage. Although the damage resulting from ... -
Physical and thermodynamic properties of aluminosilicate melts as a function of composition
(2008-04-25)Viscosity, heat capacity, density, compressibility, thermal conductivity, thermal expansion, diffusivity, surface tension of melts are all controlled by the melt structure. The structure of the melt is a function ... -
Pigments, Colours and Patterns - The contribution of eumelanin and pheomelanin to molluscan shell ornamentation with a special focus on the terrestrial snail Cepaea nemoralis
(2020-02-25)In recent years interest into molluscan pigments increased. But a lot of techniques have to be adapted to be usable with often difficult molluscan tissues and shell material. A comprehensive approach needs to encompass ... -
