The Physics and Chemistry of Oxygen-rich Circumstellar Envelopes as Traced by Simple Molecules
(2018-04-17)
The physics and chemistry of the circumstellar envelopes (CSEs) of evolved stars are not fully understood despite decades of research. This thesis addresses two issues in the study of the CSEs of oxygen-rich (O-rich) evolved ......
Measurements of differential t-channel single top-quark production cross-sections in proton–proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector
(2018-03-28)
Proton-proton collision data at a centre-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, corresponding to an integrated luminosity of 20.2 fb-1, are used to measure absolute and normalised ...
Ethologische Untersuchungen der Wahrnehmung von Oberflächenwellen des Wassers bei Krokodilen
(2018-03-23)
Krokodile nutzen zum Beutefang neben visuellen, auditorischen und olfaktorischen Reizen auch Oberflächenwellen des Wassers, die sie mit ihren Integumentary Sensory Organs (ISOs) wahrnehmen. ISOs befinden sich hauptsächlich ...
Molecular Mechanisms in the Unconventional Secretion of Insulin-Degrading Enzyme
(2018-04-12)
Extracellular deposition of amyloid-ß (Aß) plaques in the brain, a hallmark of Alzheimer’s disease (AD), results from an imbalance between production and clearance of the peptide. Insulin-degrading enzyme (IDE) is one of ...
Investigations into the DNP characteristics of electron and proton irradiated polyethylene and polypropylene
(2018-03-06)
To achieve a significant enhancement of the nuclear polarisation of solid state target materials one must use the method of dynamic nuclear polarisation. This necessitates unpaired electrons, that can be created as ...
Modulation Spectroscopy of Ultracold Atoms in Optical Lattices
(2018-03-12)
In the past fifteen years ultracold atoms confined to optical lattices, which are artificial crystals of light, have proven to be powerful tools in the study of strongly correlated many-body systems widely known from a ......
Detecting Plant Functional Traits of Grassland Vegetation Using Spectral Reflectance Measurements
(2018-03-06)
Changes in climate and an intensified agricultural use threaten grassland ecosystems in many places. To allow an efficient conservation of grassland vegetation communities, ecologists monitor variations in their plant ...
Lower semicontinuity, optimization and regularity of variational problems under general PDE constraints
(2018-04-12)
We investigate variational properties of integral functionals defined on spaces of measures satisfying a general PDE constraint. The study of these properties is motivated by the following three problems: existence of ...
The redshift distribution and dust properties of dusty star-forming galaxies at high redshift
(2018-03-27)
Millimeter (mm) and submillimeter (submm) continuum observations brought about a radical shift with the discovery that luminous, dusty galaxies were a thousand times more abundant in the early Universe than they are at ...
Study of infection induced alteration in Drosophila larval feeding behavior
(2018-03-27)
Decision making ability is a key trait that can increase an organism’s chances of survival. The animal has to constantly analyze its environment and modulate ones behavior to navigate through daily routine. This study aims ...
