Seismic soil structure interaction of navigation locks
(2017)
This work handles the seismic soil- and water structure interaction of navigation locks in the field of elastodynamics. The investigation is based on numerical analysis with the finite element method. The findings extend ...
Selenium Isotope Studies in Plants - Development and Validation of a Novel Geochemical Tool and its Application to Organic Samples
(2017)
Selenium (Se), being an essential nutrient and a toxin, enters the food chain mainly via plants. Selenium isotope signatures were proved to be an excellent redox tracer, making it a promising tool for the exploration of ...
Selenium Transfer between Kaolinite or Goethite Surfaces, Nutrient Solution and Oryza Sativa
(2016)
The aim of this study was to describe and quantify Se transfer at the interface between soil and plant. For this purpose, three Se reservoirs were defined: soil, soil solution and plant, represented by kaolinite or goethite, ...
Selection strategy and modification of layer silicates for technical applications
(2009)
In this study, samples were selected with respect to their layer charge and morphology. Sixteen bulk materials were pre-selected, which contained either swellable clay minerals or non-swelling clay minerals. One topic of ...
Selektive katalysierte Reduktion von NOx mittels NH3 an Fe-modifizierten BEA-Zeolithen
(2011)
In der vorliegenden Arbeit wurde die selektive katalytische Reduktion von NOx mittels Ammoniak an eisenmodifizierten BEA-Zeolithen untersucht. Der Katalysator zeigt gegenüber dem kommerziellen V2O5/WO3/TiO2-System eine ...
Sequentieller Versuch zur HiL-unterstützten Validierung hybrider Antriebssysteme mit gekoppelten Antriebseinheiten
(2018)
Diesel-hybrid propulsion systems for railcars are able to reduce fuel consumption and emissions in relation to conventional diesel railcars. To design such a propulsion system requires the use of simulation and experimental ...
SAR Prediction and SAR Management for Parallel Transmit MRI
(2012)
Parallel transmission enables control of the RF field in high-field Magnetic Resonance Imaging (MRI). However, the approach has also caused concerns about the specific absorption rate (SAR) in the patient body. The present ...
