The influence of environmental UVB radiation on growth, immunity, behavior and sexually selected traits in the three-spined stickleback (Gasterosteus aculeatus)
(2020-07-13)Changing photic conditions are, next to global warming, the major aspect in terms of ongoing global climate change and mainly occur within the short-wave and high-energetic ultraviolet-B (UVB) part of the electromagnetic ... -
Analyse des Lon Einflusses auf die Hitze-induzierte Aggregation mitochondrialer Proteine und auf die Bildung von Aggregatablagerungen
(2020-07-13)Die mitochondriale Matrix Protease Lon ist ein essentieller Bestandteil des mitochondrialen Protein Qualitätskontroll-Systems. Der Verlust von Lon führt zu einer erhöhten Apoptoserate und embryonaler Letalität im Mausmodell. ... -
Investigations to quantify individual exposure to solar ultraviolet erythemal radiation including cloud meteorological impact
(2020-07-09)Combined meteorological and dosimetric ultraviolet (UV) erythemal radiation (UVER) measurements were performed in 2016 and 2017. Based on collected data sets the actual UVER exposure of outdoor working probands is determined ... -
Probabilistic and differential geometric methods for relativistic and Euclidean Dirac and radiation fields
(2020-07-09)The main objective of the thesis is to study relativistic and Euclidean Fermionic quantum fields from a geometrical and probabilistic point of view as opposed to the standard treatment which is more algebraic in nature.
Gluing of metric measure spaces and the heat equation with homogeneous Dirichlet boundary values
(2020-07-09)The first part of this thesis deals with gluing together several copies of an open subset of a metric measure space along the complement. This construction results in a metric measure space. We identify the Cheeger energy ...High Performance Computing in Basin Modeling: Simulating Mechanical Compaction with the Level Set Method
(2020-07-09)The evolution of sedimentary basins is a complex set of processes developing over millions of years. Often, tectonic activity will create accommodation space that is filled in with sediments. These sediments undergo changes ...Advanced Image Reconstruction Methods for Ultra-High Field MRI
(2020-07-07)Magnetic resonance imaging (MRI) has become a very powerful and flexible medical imaging technique, that allows an unrivaled insight into human anatomy and physiology. For a wide range of possible applications, acquisition ...A 3-mm Imaging Line Survey of the Central Molecular Zones of M 82 and IC 342
(2020-07-07)The central molecular zones of two nearby galaxies M 82 and IC 342 are among the most prominent extragalactic molecular sources in the northern hemisphere. While M 82 is a relatively small late type starburst galaxy, IC ...Spectro-spatial observations of galaxy clusters with Planck and CCAT-prime
(2020-07-07)The Sunyaev-Zeldovich (SZ) effect is a spectral distortion of the cosmic microwave background (CMB) caused by inverse Compton scattering of CMB photons by free electrons in the hot intracluster medium (ICM) of galaxy ...In situ observations of reaction and transport phenomena during silicate glass corrosion by fluid-cell Raman spectroscopy: Method development and applications
(2020-07-06)Borosilicate glass is the preferred material for the immobilization of high-level nuclear waste and an important material for various industries. Silicate glasses, however, are prone to corrosion by aqueous solutions, which ...Moduli spaces of branched coverings of the plane
(2020-07-03)In this thesis I build a strong connection between Hurwitz spaces of branched coverings of the complex plane, and moduli spaces M_{g,n} of Riemann surfaces of genus g ≥ 0 with n ≥ 1 boundary components.
I refine a ...An Easton-like Theorem for all Cardinals in ZF
(2020-07-01)We show that in Zermelo-Fraenkel Set Theory without the Axiom of Choice (ZF), a surjectively modified Continuum Function θ(κ) can take almost arbitrary values on all cardinals. This is in sharp contrast ...Fettsäure-unabhängige Anpassung bakterieller Membranen an niedrige Temperaturen
(2020-07-01)Nach dem bisherigen Kenntnisstand der Forschung erfolgt die Kälteadaptation der bakteriellen Zellmembran durch die Änderung der Fettsäurezusammensetzung. In dieser Arbeit wurden Lebensmittel-assoziierte Isolate, deren ...Design & generation of an efficient E. coli cell-factory for the overproduction of the compatible solutes ectoine & hydroxyectoine
(2020-07-01)The compatible solutes ectoine and hydroxyectoine are produced by halophilic or halotolerant bacteria in order to balance and adapt to osmotic alterations in their habitat. Besides this, the potent ability of these compounds ...Die Untersuchung von wässrigen Matrices auf Rückstände antibiotisch wirksamer Substanzen mittels LC-MS/MS
(2020-06-25)Vor dem Hintergrund einer zunehmenden Resistenzproblematik und der schwerwiegenden Folgen einer möglichen Post-Antibiotika-Ära werden geeignete Analysemethoden zur Untersuchung auf Antibiotikarückstände in Umweltproben ...Multi-stage Micropattern Gaseous Detectors for the ALICE TPC Upgrade - Studying and Modelling Charge Transfer and Energy Resolution
(2020-06-23)With the upgrade of the LHC (Large Hadron Collider) at CERN, the interaction rate of ALICE (A Large Ion Collider Experiment) will be increased up to 50 kHz for Pb-Pb collisions. Thus the gated and rate-limited readout ...
