Shocks in the interstellar medium
(2014-01-09)
Shocks are ubiquitous in the interstellar medium (ISM), occurring whenever large pressure gradients lead to fluid-dynamical disturbances that move at a velocity that exceeds the local sound speed. As shocks dissipate kinetic ...
Taxonomy and ecology of amphibian communities in Southern Vietnam: Linking morphology and bioacoustics
(2014-01-16)
The Langbian Plateau is known as the southernmost extension of the Truong Son Range (or Annamite Mountains) in southern Vietnam. This area is the type locality of many amphibian species: six species described by Smith ...
Chemical Vapour Deposition Diamond: Charge Carrier Movement at Low Temperatures and Use in Time-Critical Applications
(2014-01-27)
Diamond, a wide band gap semiconductor with exceptional electrical properties, has found its way in diverse fields of application reaching from the usage as a sensor material for beam loss monitors at particle accelerator ...
On the Hilbert uniformization of moduli spaces of flat G-bundles over Riemann surfaces
(2014-01-27)
In this thesis, we study the moduli spaces M_(g,q)^m (G)of flat pointed principal G-bundles over Riemann surfaces X. The genus of X is g 0 and G is a fixed Lie group. Further, we are given m 0 permutable marked points in ...
Mechanismen zur Erzeugung von Flüssigkeitsstrahlen im Tierreich am Beispiel von Pistolenkrebsen und Speikobras
(2014-06-04)
Verschiedene Tierarten sind in der Lage mit hoher Präzision und Geschwindigkeit kurze, pulsartige Flüssigkeitsstrahlen zu erzeugen. Die Tiere nutzen zur Strahlerzeugung unterschiedliche Organe, Mechanismen und Flüssigkeiten. ......
Untersuchungen zur Phylogenie der Cirratulidae (Annelida)
(2014-02-07)
Die phylogenetische Position der Cirratulidae innerhalb der sedentären Polychaeten ist bisher nicht zufriedenstellend aufgeklärt. Historisch wurden die Cirratulidae nahe zu den Spionidae bzw. zu den Terebellida gezählt. ...
Systematic Study of Hadronic Molecules in the Heavy Quark Sector
(2014-01-17)
In this work we have studied properties of hadronic molecules in the heavy quark sector. These have become increasingly important since from the beginning of this century a large number of states have been measured that ...
Molecular pathomechanisms of epilepsy-associated gangliogliomas
(2014-01-14)
Gangliogliomas represent chronic epilepsy associated low-grade brain tumors, composed of dysmorphic neurons as well as proliferative glial cells. To date, the molecular pathomechanisms leading to the manifestation of these ......
Vulnerability Assessment of Different Socio-Economic Groups to Floods in the Rural Mekong Delta of Vietnam
(2014-09-26)
The objective of the study is to identify and understand the different factors that characterize vulnerability towards slow-onset floods in rural areas of the Vietnamese Mekong Delta. This thesis aims to explore losses and ...
Properties of pseudoscalar flavor singlet mesons from lattice QCD
(2014-02-18)
The central topic of this work are masses and mixing parameters of the η-η' system, which are investigated within the framework of Wilson twisted mass lattice QCD, using gauge configurations provided by the European Twisted ...
