The role of soluble guanylate cyclase in metabolism
(2018-10-31)
Obesity is a worldwide health problem characterized by a chronic positive energy balance. The excess energy is stored primarily as lipids (TGs) in white adipose tissue (WAT). In contrast, brown adipose tissue (BAT) utilizes ...
Suberin biosynthesis in barley roots in response to osmotic stress
(2018-10-31)
In future climate change will intensify extreme weather conditions, such as drought, which will lead to decreased yields of crops. A decrease in soil water potential is the first signal of potential drought stress for ...
Influence of the St John´s wort extract Ze117 and selected ingredients on membrane fluidity and phospholipid composition in rat C6 glioblastoma cells
(2018-10-31)
Chronic stress has been recognized to represent a key factor for the development of depression. Among others cortisol has been described to mediate an adaptive effect on plasma membrane fluidity which may affect signal ...
An Investigation of Constraints on Dark Matter Models from Mono-jet Searches at LHC
(2018-10-31)
In this work we investigate the Weakly Interacting Massive Particle (WIMP) dark matter searches in colliders. We focus on the mono-jet searches and derive the upper bounds on the WIMP production cross-sections at the LHC. ...
Bestimmung der Doppelpolarisationsobservablen E in der Reaktion γ⃗p⃗ → pη am CBELSA/TAPS-Experiment in Bonn
(2019-03-07)
Photoproduktionsdaten beeinflussen zunehmend unser Bild der tatsächlich in der Natur existierenden Baryon-Resonanzen. Die Analyse von (Polarisations-)Observablen ist entscheidend für die Extraktion von Resonanzen aus diesen ......
Investigation of Multipotent Neural Progenitor Cell to Oligodendrocyte Differentiation including the Transcriptional Activator Protein Pur-alpha by Quantitative Proteomics
(2019-02-26)
Oligodendrocytes are neuroglial cells, localized in the white matter of the central nervous system. They develop from neural stem cells (NSCs), which produce, among others, migrating and proliferating oligodendrocyte ...
On discrete surfaces: Enumerative geometry, matrix models and universality classes via topological recursion
(2019-03-21)
The main objects under consideration in this thesis are called maps, a certain class of graphs embedded on surfaces. We approach our study of these objects from different perspectives, namely bijective combinatorics, matrix ...
Identification of components and substrates of Snf1-related kinase 1 (SnRK1) complexes in Arabidopsis thaliana
(2019-04-04)
Similarly to yeast Sucrose nonfermenting 1 (Snf1) and animal AMP-activated protein kinases (AMPKs), plant Snf1-related (SnRK1) kinases play a central role in the regulation of cellular energy homeostasis and responses to ......
Pore-Scale Modelling of Induced-Polarization Mechanisms in Geologic Materials
(2019-03-20)
This thesis is concerned with mechanistic pore-scale models, which relate the induced-polarization (IP) response of geologic materials to the underlying physical and chemical processes. Although a sound understanding of ...
Light Propagation in Digital Material Structures
(2019-03-26)
Light takes many paths throughout the physical environment, defined by a multitude of interactions with matter, before reaching an imaging sensor or the human eye and thus forming the visual perception of the world. ...
