Alkalien in Chondren - offenes oder geschlossenes System?
(2009-05-05)Sodium as trace element in olivine can be measured by electron-microprobe and using high currents (<600nA). The lower limit of detection is 0.0015 wt.% Na2O in olivine. Results are veryfied ... -
An integrated approach for the investigation of unconsolidated aquifers in a brackish environment - A case study on the Jordanian side of the lower Jordan Valley
(2008-09-18)In semi-arid areas groundwater systems are frequently not sufficiently characterized hydrogeologically and long term data records are generally not available. Long-term time series are necessary, however to design future ... -
An Integrated Approach of Analyzing Management Solutions for the Water Crisis in Azraq basin, Jordan
(2017-05-18)Natural groundwater replenishment in (semi-) arid areas is low and can be sometimes negligible as a result of low precipitation rates and high evapotranspiration. Therefore, groundwater resources in these areas can be ... -
An integrated approach to the study of biosignatures in mineralizing biofilms and microbial mats
(2011-02-02)In this thesis project, biomarkers, biomineralization processes and TREE (trace and rare earth elements) patterns in mineralizing microbial mats were established and tested as biosignatures ... -
An unusually complete suite of eclogite types: Eclogite xenoliths from the Zero kimberlite, South Africa
(2003-04-14)This first investigation of eclogite xenoliths sampled by the Zero kimberlite show that the suite is exceptional concerning kimberlite age and diversity of eclogite types. The Zero kimberlite ... -
Analyse der vierperiodischen Minimalnetze
(2015-03-06)Periodic structures – e. g. crystal structures – are analyzed by means of group theory. The concept of a crystal structure is extendable to the n-dimensional space and the 4-dimensional space groups are known [Brown, ... -
Analyse spektroradiometrischer in situ Messungen als Datenquelle für die teilflächenspezifische Zustandsbeschreibung von Winterweizenbeständen
(2002-08-28)Against the background of the political, economical and societal situation in the agronomic sector, there is an increasing demand for spatio-temporal high resolution data for a site specific ... -
Analyses of hydrological and hydrochemical fluxes in selected catchments of the Cerrado and Amazon biomes
(2019-03-12)On many levels, there is a lack of understanding regarding the impacts of deforestation on water resources and soil properties in the Amazon-Cerrado ecotone, where the Amazonian agricultural frontier is mostly present. ... -
Anoxic sediments and their potential to favour bacterial wood decay
(2007-10-30)Wooden pile foundations are widely used along coastal areas and river sites in Europe to support historic buildings. When the ground water level is low these wooden structures are exposed ... -
Anwendung multiparametrischer Fernerkundungsdaten zur Ökosystem-Kartierung und Regionalisierung von Transpirations-Flussmessungen in Zentralsibirien
(2002-05-08)For the central Siberian study area a postprocessing of SAR (Synthetic Aperture Radar) remote sensing data from ERS (European Remote Sensing Satellite) and JERS (Japanese Earth Resources ... -
Application of Garnet in Sedimentary Provenance Analysis
(2015-11-13)This PhD thesis investigates the application of heavy minerals in sedimentary provenance analysis, with the main focus on garnet geochemistry. The work is mainly based on an intensive literature study, fieldwork, conventional ... -
Applying Organic Compounds as Indicators in Innovative Monitoring Strategies
(2019-08-07)Today, demands on water quality are diverse and strongly differ by water use related criteria. Additionally, the complex topic of water quality is of increasing importance for citizens and is therefore often emotionally ... -
Assessing the formation and preservation of organic signatures in extreme environments in the context of the ExoMars 2020 rover mission
(2019-09-20)The search for extraterrestrial life is one of the greatest scientific quests of our time. The ESA/Roscosmos ExoMars 2020 rover mission seeks to find evidence for past or modern life on Mars by investigating (sub-)surface ... -
Assessment of Drought in Grasslands: Spatio – Temporal Analyses of Soil Moisture and Extreme Climate Effects in Southwestern Mongolia
(2021-06-28)Soil moisture plays an essential key role in the assessment of hydrological and meteorological droughts that may affect a wide area of the natural grassland and the groundwater resource. The surface soil moisture distribution ... -
Assessments of phenotypic variations and variability as a tool for understanding evolutionary processes in echinoids
(2016-07-20)The following three chapters can be regarded as thematic complexes of studies on phenotypic variations and variability in order to elucidate their origins on a systematic hierarchy-level in echinoids. Chapter 2 seeks ... -
Auslaugung anorganischer Schadstoffe aus Abfall- und Altlastmaterialien
(2005-06-22)Ten waste and refuse materials were filled into small lysimeters in layers of 50 cm thickness. They were covered with three top-soils of varying pH (sandy forest soil, sandy arable soil and ... -
Auswirkungen des regionalen Klimawandels auf die Entwicklung der Biomasseerträge ausgewählter landwirtschaftlicher Nutzpflanzen in Niedersachsen
(2013-12-13)Lower Saxony (total land area about 46,500 km2) constitutes one of the most important agricultural areas in Germany and thus within Europe. However today, there exists no comprehensive account on the impacts of climate ... -
