Contesting Rural Futures: Political and Agrarian Change in Tanzania's Kilombero Valley during the Presidency of John P. Magufuli (2015 - 2021)
(2023-06-19)
The Arusha Declaration, written by the state founder Julius Nyerere in 1967, was replaced around the year 2000 by a new national development vision, Vision 2025. State visions of the future of the nation on the one hand ...
Analysis of the MBO scheme: from materials science to data clustering
(2023-06-15)
The Merriman, Bence, and Osher (MBO) scheme -- also known as thresholding scheme -- is a numerical method originally introduced to approximate the evolution by mean curvature flow (MCF). The algorithm produces a time ...
Modular q–difference equations and quantum invariants of hyperbolic three–manifolds
(2023-04-28)
In this thesis, we take up the study of quantum invariants of hyperbolic closed three manifolds. In particular, we consider the behaviour of the Witten-Reshetikhin-Turaev invariants associated to the Lie algebra of the ...
GLOSTAR: Investigating Tracers of Early High-Mass Star Formation
(2023-05-12)
High-mass stars (>8 msol) are not as numerous as their less massive counterparts but have a much more profound impact on their environment within their native galaxies. Despite their importance, our understanding of their ...
Baryon properties from chiral QCD
(2023-06-05)
This thesis contains a collection of studies on the properties of baryons within the context of effective field theory, especially Chiral Perturbation Theory. The thesis focuses primarily on the Roper resonance, an excited ...

(2023-04-17)
An der Beschleunigeranlage ELSA am Physikalischen Institut der Universität Bonn werden gegenwärtig zwei Experimente betrieben, welche die innere Struktur der Nukleonen untersuchen. ELSA zeichnet sich insbesondere durch die ...
Enantioselektive Totalsynthese von (+)-Salimabromid und Studien zur Synthese von Acyldepsipeptiden
(2023-04-19)
Salimabromid
Das aus dem marinen Myxobakterium, Enhygromyxa salina, isolierte Polyketid, Salimabromid, wurde mit seinem neuartigen Kohlenstoffgerüst in einer enantioselektiven Totalsynthese ......

Next-Generation Electronics for the Read-Out of Micro-Pattern Gaseous Detectors
(2023-04-20)
Developed by the RD51 collaboration, the Scalable Readout System (SRS) is widely used for the read-out of Micro-Pattern Gaseous Detectors (MPGDs). With different front-end Application-Specific Integrated Circuits (ASICs) ...
Neuroanatomie und Funktionsmorphologie Peripherer Rezeptorneurone mit Direkten Projektionen in das Protocerebrum des Insektengehirns
(2023-04-20)
Zur Wahrnehmung unterschiedlicher thermischer Reize hat sich bei Insekten eine Reihe von Thermorezeptoren entwickelt. Der pyrophile („feuerliebend“) „Australische Feuerkäfer“ (Merimna atrata) besitzt paarige Infrarot-(IR)-Organe ......
Ectopic expression of transcription factors to overcome the lineage barrier between embryonic stem cells and trophoblast stem cells in mouse and human
(2023-04-19)
The placenta is a transient organ that exhibits various essential functions during pregnancy that allow for proper development of the embryo. Placenta and embryo originate from the first lineage separation in mammalian ...
