Sedimentation of particle suspensions in Stokes flows
(2020-05-14)
In this thesis, we consider problems arising from the physical phenomenon of particle sedimentation. We focus on non-Brownian particles in fluids at zero Reynolds number. Microscopically, the particle
system is described ...
Proteomic identification of posttranslational modifications: cAMP-induced changes of phosphorylation and investigation of novel approaches detecting posttranslational modifications at lysine and arginine residues
(2020-04-22)
Cyclic adenosine monophosphate (cAMP) is an important second messenger which can be generated in response to signals binding to stimulatory G-protein coupled receptors. Inside the cell, protein kinase A is a well-known ...
Approximation Algorithms for Traveling Salesman Problems
(2020-04-15)
The traveling salesman problem is the probably most famous problem in combinatorial optimization. Given a graph G and nonnegative edge costs, we want to find a closed walk in G that visits every vertex at least once and ...
Palladium-katalysierte regiodivergente Carboaminierungen und -veretherungen
(2020-04-08)
Ziel der Arbeit war, ein robustes System zur intermolekularen Palladium katalysierten regiodivergenten Carboaminierung zu entwickeln und die Grenzen der Substratpalette dieses Prozesses zu erforschen. Der Fokus der Arbeit ...
Spaceborne SAR Remote Sensing for Monitoring of Vegetation Dynamics in Arid and Semi-arid Environment
(2020-04-22)
Drylands are under constant threat from multiple stresses and challenges, which occur as a result of a complex interaction of natural processes, and human-induced processes caused by unsustainable land use practices, leading ...
Impact of UGT1A polymorphisms on inflammation and fibrogenesis in a humanized transgenic mouse model
(2020-07-07)
Fibrogenesis represents a highly dynamic scarring response of the liver resulting from different causes of hepatic injury. A key process capable of activating a broad array of profibrogenic pathways is oxidative stress. ...
Stereoselektive Polyolsynthese zur Untersuchung von Wasserstoffbrückenbindungen mittels IR-Spektroskopie
(2020-12-11)
Um die anomalen Eigenschaften des Wassers gänzlich zu verstehen, ist die intensive Untersuchung von Wasserstoffbrücken erforderlich. IR-spektroskopische Messungen vernetzter Flüssigkeiten liefern dabei eine Fülle an ...
Optimierung der GEM-basierten Verstärkungsstufe einer TPC für das CB/TAPS-Experiment
(2020-08-10)
Das CB/TAPS-Experiment widmet sich der Untersuchung des Spektrums angeregter Hadronen. In seinem aktuellen Aufbau ist es dabei auf die Identifikation und der Vermessung ungeladener Endzustände spezialisiert. In einer ...
Microevolutionary processes and taxonomic investigations of the Atacama Desert flora
(2020-12-22)
Plant evolutionary processes in the hyper arid Atacama Desert of northern Chile are here investigated using our species/species complexes as case studies based on the following research questions:
(1) Are populations ......
(1) Are populations ......
Probing the Standard Model of particle physics with ttH, WWZ and WZZ multilepton final states
(2020-01-13)
The Standard Model of particle physics elegantly describes the fundamental constituents of matter and their interactions. The electroweak gauge and top-quark Yukawa couplings can be directly probed in the associated ...
