The role of post-harvest supplementary light exposure for ripening and quality development of tomato fruit
(2020-11-23)
The major aim of the present work was to evaluate the optimal exposure time and effects of red light and short periods of daily ultraviolet (UV) on the post-harvest quality of green tomato fruit during ripening. The ...
Radio emission from massive Young Stellar Objects and their surroundings: Characterization and feedback
(2020-10-12)
Massive stars or high-mass stars dominate their galactic environments. They play a major role in the energy budget of galaxies and are essential in their evolution. However, high mass star formation is not fully understood, ...
Root-restricting layers in German agricultural soils: Extent, cause and management strategies
(2020-10-21)
Subsoil, i.e., soil below 30 cm depth, harbours great amounts of water and nutrients. However, physical and chemical barriers for vertical root elongation may restrict plants from accessing subsoil resources. Such ...
On the theory of higher Segal spaces
(2020-10-21)
This thesis contains three chapters, each dealing with one particular aspect of the theory of higher Segal spaces introduced by Dyckerhoff and Kapranov:
(1) By exhibiting the simplex category as an ∞-categorical ...
(1) By exhibiting the simplex category as an ∞-categorical ...
Determinants of Human Capital Formation
(2020-08-25)
Human capital is crucial for individuals’ economic prosperity. As such, differences in human capital are largely responsible for existing inequalities within society, making it essential to understand the determinants of ...
Ribosome profiling of selenoproteins in vivo reveals consequences of pathogenic Secisbp2 missense mutations: The establishment of translating ribosome affinity purification
(2020-11-04)
Recoding of in-frame UGA/Seccodon in selenoproteins requires a complex translational machinery. The core of this event is the interaction between selenocysteine insertion sequence (SECIS element) in the 3’UTR of ...
Synthese und Charakterisierung von Lithium-metall(I)-phosphaten: Die strukturelle Differenzierung von einwertigen Kationen in multinären Phosphaten
(2020-12-01)
Die vorliegende Dissertation behandelt die Synthese und Charakterisierung neuer Lithium-metall(I)-phosphate (M = Cu+ , Na+ , Ag+ ). Dabei wurde nach der ......
Verlauf der Hepatitis-B-Marker unter Langzeit-Nukleosid(t)-Behandlung am Beispiel der Köln/Bonner HIV/HBV-Koinfektionskohorte
(2020-05-28)
Einleitung: Patienten mit HIV haben ein sechsfach erhöhtes Risiko aus einer akuten Hepatitis-B-Infektion eine chronische Hepatitis-B-Infektion zu einwickeln. Unter suffizienter ART mit HIV/HBV-wirksamer Nukleosid( ...
Untersuchungen zur Synthese von Silber-Übergangsmetallphosphaten in den Systemen AgO0,5 / MOX / PO2,5 (M = Mn, Fe, Co, Ni, Cu, Zn, Cd) und zur oxidativen Kopplung von Phosphatgruppen im Festkörper
(2020-06-10)
Im Rahmen dieser Arbeit wurde die Familie der Silber-übergangsmetall-phosphate um einige Vertreter erweitert. Die isotypen Pyrophosphate Ag2Cd3(P2O7)2 und Ag2Zn ...
Optical spectroscopy and applications of atomically precise graphene nanoribbons: from light emission to photodetection
(2020-11-16)
Atomically precise graphene nanoribbons (GNRs) are narrow stripes of graphene with a width of a few atoms and a well-defined edge structure. On-surface synthesis of GNRs from molecular precursors enables atomic precision ...
