Long-term timing of pulsars in globular clusters
(2017-12-20)
Pulsars are fast rotating, magnetized neutron stars that result from the supernova explosion of massive stars. Thanks to their coherent radiation, emitted in the form of collimated beams from the two magnetic poles, pulsars ...
Production and PAC studies of 83Rb/83mKr solid state calibration sources for the KATRIN experiment
(2017-12-13)
The KATRIN experiment studies the tritium beta-decay kinematics to deduce the neutrino mass. The emitted electrons' kinetic energy close to the beta-spectrum's endpoint is analysed using a high-precision Magnetic Adiabatic ...
Search for Flavour Changing Neutral Currents through Single Top-Quark Production at √s= 8 TeV with the ATLAS Detector
(2017-12-20)
Flavour changing neutral current processes are highly suppressed in the Standard Model due to the Glashow-Iliopoulos-Maiani mechanism. However, many extensions of the Standard Model predict the existence of these processes ......
Mechanobiologische Untersuchungen zur Rolle von Keratin, Aktin und Adhärenzverbindungen während der Differenzierung epithelialer Zellen in vitro
(2017-12-18)
Bei genetischen Erkrankungen wie Epidermolysis bullosa simplex sind die mechanischen Eigenschaften der Hautzellen verändert und die Integrität der Haut gestört, wodurch ihrer Fragilität erhöht ist und eine funktionelle ...
Functional characterisation of glutaredoxin S15 from Arabidopsis thaliana
(2017-12-13)
Iron-sulfur clusters (ISCs) are essential cofactors that are composed of iron and inorganic sulfur. A complex assembly pathway conveys their initial synthesis and subsequent binding to the respective apoproteins. With the ......
The role of endocannabinoid system in neuron-glial communication in the ageing and diseased brain
(2017-12-13)
The endocannabinoid system has been implicated in the regulation of glial activity and progression of brain ageing. Mice constitutively or specifically lacking the cannabinoid receptor 1 (CB1) on neurons or GABAergic neurons ...
Rational global homotopy theory and geometric fixed points
(2017-12-20)
We use geometric fixed points to give a multiplicative algebraic model for rational global homotopy theory with respect to finite groups. It has infinite homological dimension and we study the formality of K-theory. ...
Influence of the Conformation of Conotoxins on their Bioactivity
(2017-12-14)
In the last decade peptides filled the gap between small molecule drugs and biologics as therapeutics. A rich source of such peptides represents the venom of different animals evolved over millions of years. Conotoxins are ...
Topics in chiral perturbation theory for charmed mesons
(2017-10-10)
This thesis is concerned with topics in chiral perturbation theory for pseudoscalar charmed mesons in a manifestly Lorentz-invariant way. After constructing the chiral effective Lagrangian describing spinless matter fields ...
Fluid driven processes in the crust – the formation of anorthositic dykes in the Troodos ophiolite (Cyprus)
(2017-10-12)
Anorthositic dykes related with the Upper Cretaceous Troodos ophiolite are described for the first time. An entire anorthosite dyke swarm appears within the Limassol Forest Complex, crosscutting the supply channels of late ...
