Transfer of Main and Trace Elements from Soil to Plant with an Emphasis on Trace Element Supply for Biogas Digestion Plants
(2018-10-01)In this study trace element uptake by different plants and plant species on different soils was investigated. A special focus was on the uptake of the elements Co, Ni, Mn and Mo, as those were essential elements for ... -
Transfer of Nutrient and Harmful Elements from Soil to Rice and Health Risk Assessments for the Vietnamese Population
(2019-10-11)“Transfer of nutrient and harmful elements from soil into rice and health risk assessments for the Vietnamese population” Main and trace element concentrations in paddy soils and corresponding rice plants collected along ... -
Triple oxygen (16O, 17O, 18O) and carbon (12C, 13C) isotope variations in bioapatite of small mammals – new insights concerning the reconstruction of palaeo‐CO2 concentrations and palaeotemperatures
(2013-02-25)The ratios among the stable isotopes of oxygen (16O, 17O, 18O) and carbon (12C, 13C) in biogenic apatite of mammal teeth and bones have the potential to provide insight into the isotopic composition of the respective oxygen ... -
Triple oxygen isotope ratios of bioapatite
(2022-04-07)Bioapatite is the major crystalline component of bone and tooth materials. Recent studies demonstrated that bioapatite carries information of animals’ physiology and living environmental conditions and retains its original ... -
Triple oxygen isotope study on the Earth-Moon system
(2021-12-23)Triple oxygen isotope systematics (Δ'17O) are an established tool to trace and classify extraterrestrial material. This tool is used in the field of cosmochemistry to study the genetic link between different Solar System ... -
Triple oxygen isotope variations in natural and anthropogenic carbon dioxide
(2013-03-19)The oxygen and carbon isotope composition (18O/16O and 13C/12C) of atmospheric carbon dioxide is an excellent tool to investigate the atmospheric CO2 cycle. In recent ... -
Triple Oxygen Isotopes of Cherts : Implications for the δ18O and Temperatures of Early Oceans
(2017-06-19)The temperature of Earth’s earliest oceans, in which life may have first originated, remains a controversial issue in Earth science. Over the last 50 years, many studies have attempted to apply the temperature dependent ... -
Turbulent Fluxes of CO2, H2O and Energy in the Atmospheric Boundary Layer above Tropical Vegetation investigated by Eddy-Covariance Measurements
(2005-02-09)The conversion of tropical rainforest to agriculturally used land is a spreading process throughout Indonesia and South-East Asia. Besides the effects on the biological diversity and the ... -
Ultrasonic tomography for the characterization of the weathering state of marble
(2021-05-25)The present thesis investigated the application of ultrasonic tomography to evaluate the weathering condition of different marble varieties. Ultrasound analysis is a non-destructive examination method which is often used ... -
Understanding heat transport processes in shallow subground resulting from external and internal impacts
(2024-01-18)Heat conduction in the subsurface environment is the result of internal and external impacts and is governed by different forces in the short and long term. Externally, this phenomenon is related to daily temperature ... -
Unmixing of Phosphorus-bearing Melts on Earth and Mars
(2019-04-17)The aim of this study lies in the investigation on unmixing in aluminosilicate melts. Therefore, six glasses of peralkaline and peraluminous compositions were synthesized in the system CaO-Al2O3-SiO2, Na2O-Al2O3-SiO2 and ... -
Urbanisation, Land Use and Soil Resource: Spatio-Temporal Analyses of Trends and Environmental Effects in Two Metropolitan Regions of Ghana (West Africa)
(2020-12-23)With more than half of the world’s population already urbanised, global sustainability is partly hinged on how the urbanisation process is impacting the natural environment. Therefore, it is important to characterise, ... -
USE OF GIS MODELLING IN ASSESSMENT OF FORESTRY LAND'S POTENTIAL IN THUA THIEN HUE PROVINCE OF CENTRAL VIETNAM
(2008-07-22)Land suitability assessment is a prerequisite for sustainable forestry production. It involves simultaneous consideration of geo-morphological and ecological factors and environmental and socio-economic aspect ... -
Use of selected anthropogenic pesticides, nutrients, and biomarkers to spatially and temporally characterize eutrophication dynamics at a shallow lake (Lake Seeburg)
(2022-11-09)Eutrophication of water bodies caused by high nutrient inputs, especially of phosphorus, is a global concern for a wide variety of ecosystems. To assess this problem, different monitoring approaches have been applied to a ... -
