Janus Kopf Liganden in heterobimetallischen Komplexen
(2010-11-26)This thesis includes studies on the Janus-head ligand di(benzothiazole-2-yl)phosphane. An improved synthesis and modifications of the ligand are reported. Additionally different mono- and ... -
JI-3D A new approach to high resolution regional seismic tomography: Theory and applications
(2003-06-05)Seismic tomography is one of the most important means to image the internal structure of the Earth. Restricted array teleseismic tomography determines the 3D-distribution of velocity ... -
Julia Set as a Martin Boundary
(2010-11-18)The Julia set of the class of hyperbolic rational maps having a totally disconnected Julia set is here identified as the Martin boundary of a Markov chain by using symbolic dynamics. When ... -
Jump estimation for noisy blurred step functions
(2006-09-18)We consider the estimation of a step function $f$ from noisy observations of $Kf$, where $K$ is some integral operator with bounded integral Kernel. We use a penalized least squares estimator ... -
Junge Erwachsene als Zielgruppe für den Bio-Markt
(2007-12-07)This study investigates young adults as a target fort he organic food market. The recent growth of the organic market was accompanied by a change in it s consumers. Unlike in the beginning ... -
K-Ar-Datierungen an detritischen Muskoviten und Sm-Nd-Modellalter prä- und synorogener schwach metamorpher Sedimente im Rhenoherzynikum - Grundlegende Daten zur Quantifizierung orogener Prozesse am Beispiel der Varisziden
(2001-07-06)The combination of K-Ar cooling ages of detrital muscovites, Sm-Nd model ages and geochemical investigations allows the discrimination of four crustal segments as provenance areas for the ... -
Kartierung von umhüllungsrelevanten Aminosäureresten auf dem Hepatitis B Virus Kapsid
(2004-07-30)During morphogenesis of the hepatitits B virus (HBV) the cytosolic build nucleocapsid containing the viral genome interacts with transmembrane viral surface proteins to get enveloped into ... -
Kationen-Ordnung in ferri/ferromagnetischen perowskitischen Dünnfilmen
(2015-07-27)A major obstacle to the applicability of oxide perovskites in electrical or spintronic applications is the size of the specific temperatures at which the physical phenomena such as ferromagnetism or high-temperature ... -
Kationordnung und Grenzflächeneffekte in stark korrelierten Elektronensystemen
(2021-10-05)The work is about cation ordering and interface mechanism in strongly correlated electron systems -
Kausales Denken, Bayes-Netze und die Markov-Bedingung
(2010-02-09)The ability to discover and use causal relationships is crucial for acting successfully in the world. A dominant current framework to model everyday causal knowledge are causal Bayes nets, ... -
Kenngrößen für die Abhängigkeitsstruktur in Extremwertzeitreihen
(2010-11-26)The extreme value dependence structure in uni- as well as multivariate time series may be described in a simplified way using suitable characteristics. These include concepts such as the ... -
“Keratose” sponge fossils and microbialites: a geobiological contribution to the understanding of metazoan origin
(2015-02-18)Molecular clock and the fossil record at the Precambrian-Cambrian boundary indicate that animals probably had a long evolutionary history in the Precambrian which is still poorly explored and understood. This PhD study was ... -
Key Stakeholders in the Common Agricultural Policy: Farmers' Economic Well-Being, Attitudes, and Environmental Behavior
(2023-02-01)The Common Agricultural Policy (CAP) shapes the agri-food sector of the European Union (EU) by mainly regulating the distribution of financial support to agricultural producers. Based on the Treaty of Rome (1957), one of ... -
Kinematic dynamo onset and magnetic field saturation in rotating spherical Couette and periodic box simulations
(2013-07-26)Magnetic fields are ubiquitous in the universe and can be found in celestial bodies, galaxies, stars including our Sun and planets like the Earth or Jupiter. Due to the fact that at least in the Earth's interior, temperatures ... -
