Seagrass as a Sustainable Alternative for Building Materials: Assessing its Feasibility, Processing Methods, and Performance in Construction
(2023-12-08)Seagrasses are vital contributors to the ecosystem, absorbing atmospheric CO2 and generating oxygen for marine life. However, when they decompose, the accumulated biomass along the shores can lead to concerns like CO2 and ... -
Computational analysis of transcriptional regulation and chromatin assembly
(2023-12-07)Primordial germ cells (PGCs), the precursors of gametes, are specified from post-implantation epiblast cells in response to bone morphogenetic protein (BMP) signaling at the onset of gastrulation in mouse. Followed by ... -
Geographic Indications as flagship products for sustainable landscape management in the European Union
(2023-12-04)This Ph.D. thesis addresses the broader topic of sustainable landscape management in European agriculture, with a specific focus on the potential of labeling as a tool contributing to achieving such a goal. The cumulative ... -
Non-equilibrium Phases in Jahn-Teller-distorted Perovskite Manganites
(2023-12-04)Optical control of condensed matter, being inherently fast and energy efficient, sparks hope for potential technical applications. However, these require a fundamental understanding of the physical mechanisms behind. In ... -
Produktionsökonomische Analyse von Tierwohlmaßnahmen in typischen Milchviehbetrieben Nordwestdeutschlands
(2023-12-01)Farm animal husbandry is the most important sector of the German agriculture and food industry. With an overall share of 22 percent of the production value of agriculture, milk production is of particularly great economic ... -
Breeding for Improved Flavour of Fresh Market Tomatoes: Breeders' Sensory Test and Molecular Markers
(2023-12-01)Until recently, flavour was not a primary breeding target in tomatoes (Solanum lycopersicum L.). However, the poor flavour of tomatoes is a major cause of consumer complains. Flavour results from a complex interaction ... -
The effect of global change on multitrophic interactions of sugar beet
(2023-12-01)Global climate change models predict changes in rainfall patterns and rising sea levels, resulting in severe drought and soil salinity, which are already observed in many countries worldwide. Abiotic stressors such as ... -
Local and landscape threats to bee and wasp populations in agricultural landscapes
(2023-12-01)The transformation and intensified use of the agricultural landscape in central Germany in the past decades has led to the fragmentation and loss of semi-natural habitats, threatening biodiversity including insects. Bees ... -
Influence of forest machine operator work practices and operator assistance systems on the efficiency of fully mechanized timber harvesting systems
(2023-12-01)Introduction: Fully mechanized harvesting systems consisting of harvesters and forwarders represent state-of-the-art technology within modern timber harvesting operations. The droughts of the past years, consecutive ... -
Linking crop modelling and experimentation to fully exploit genotypic diversity in barley for climate change adaptation in Europe
(2023-11-28)Summary Future barley production in Europe is projected to face severer and more frequent climate extreme events. Projections have also shown that potential climate-change induced yield losses can be significantly ... -
The enzymatic product of SH2 domain-containing inositol 5-phosphatases supports the fitness of BCR-dependent Burkitt lymphoma cells by promoting the energy metabolism
(2023-11-23)Burkitt lymphoma (BL) is an aggressively growing neoplasm owing to an over expression of the MYC oncogene and exploitation of the tonic B cell receptor (BCR) signaling for its survival. While it is known that the survival ... -
Improving the analysis of aeroacoustic measurements through machine learning
(2023-11-20)This thesis focuses on improving the analysis of aeroacoustic imaging methods using automated data processing and machine learning. Imaging methods result in beamforming maps that are challenging to explore manually since ... -
Adaptive numerical methods for optimal and branched transport problems
(2023-11-20)Optimal transport is an area of mathematical research that has been gaining popularity in recent years in various application fields such as economics, statistics or machine learning. Two important factors behind its ... -
Ultrafast spin dynamics in FeNi alloys
(2023-11-17)In this thesis, the optical intersite spin transfer in ferromagnetic FeNi alloys is studied on the femtosecond timescale. Extreme ultraviolet transverse magneto-optical Kerr effect spectroscopy (EUV T-MOKE) is used to ... -
Symmetries and correlations in solids probed by ultrafast high-harmonic spectroscopy
(2023-11-13)Novel material systems with correlated and tunable properties promise to push the boundaries of current information processing and energy management technologies. Their investigation requires simultaneous access to multiple ... -
Testing tube model predictions on semi-flexible polymer networks
(2023-11-13)The mechanical properties of simple entangled actin filament networks in eukaryotes are well understood as they are predictable with model systems. The high complexity of cellular actin structures like the cell cortex for ... -
Diophantine problems: inequalities and abelian varieties
(2023-11-10)In this thesis we consider the density of rational points near manifolds and a bound for the torsion on a simple abelian variety of type IV over a number field. In the first part the main result is an asymptotic for the ... -
Beyond the Blemishes
(2023-11-09)A significant amount of food produced worldwide is lost and wasted along the supply chain. The Food and Agriculture Organization of the United Nations (FAO) estimates that approximately 13 % of food is lost between harvest ... -
