Lichtinduzierte Depression: Etablierung eines neuen Mausmodells zur Untersuchung depressiver Erkrankungen beim Menschen
Becker, Astrid (2011-05-04)Etwa 16 % der Weltbevölkerung erleiden mindestens einmal in ihrem Leben eine depressive Episode. Von den Betroffenen sprechen jedoch nur weniger als ein Drittel auf die eingesetzten Antidepressiva an. Eine bessere und ... -
Lichtinduzierte Primärprozesse des stabilen Radikals 1,3,5-Triphenylverdazyl
Weinert, Christoph (2016-06-07)Zum Verständnis eines jeden chemischen oder biochemischen Prozesses sind detaillierte Informationen über die Kinetik intra- und intermolekularer Energieumverteilung unverzichtbar. In der kondensierten Phase spielen ... -
Lichtinduzierter Ladungstransport in undotierten Lithiumniobat-Kristallen
Lüdtke, Fabian (2012-06-14)Die Kombination von optischer Nichtlinearität und der Möglichkeit zur ferroelektrischen Domänenstrukturierung machen Lithiumniobat-Kristalle zu einem der wichtigsten Materialien im Bereich optischer Technologien. Unerwünschte ... -
Lichtkräfte auf einen Indiumatomstrahl
Klöter, Bernhard (2007)Die atomare Nanostrukturierung (atomic nanofabrication, ANF), d. h. das kontrollierte Abscheiden von Atomen auf einem Substrat bietet interessante Perspektiven, wenn zwei atomare Spezies benutzt werden. Besonders interessant ... -
Lidarbeobachtungen der polaren Atmosphäre: Wolken und Wellen – Phänomene und Mechanismen
Blum, Ulrich Alois (2003)Since 1997 the Bonn University Institute of Physics operates a Rayleigh/Mie/Raman lidar on the Esrange near the Swedish city of Kiruna north of the Arctic circle. During seven winter and six summer campaigns a large amount ... -
Life History and Mating Behaviour of the Scorpionfly Panorpa alpina Rambur (Mecoptera): Choice and Strategy = Lebensgeschichte und Paarungsverhalten der Skorpionsfliege Panorpa alpina Rambur (Mecoptera): Wahl und Strategie: With Remarks on the Methods of Causal Modeling = Mit Anmerkungen zu den Methoden der kausalen Modellierung
Bornemann, Gerhild (2013-05-07)Life history theory bases on the fundamental assumption that the behaviour of living things at any time of their lives aims at the maximisation of their reproductive success. The present thesis adopts this assumption, which ... -
Ligandenfeldanalyse im Rahmen des Angular Overlap Model an einer Reihe von Samarium(III)-oxoverbindungen mit ergänzenden Betrachtungen zu Europium(III)-oxoverbindungen
Kannengießer, Nils (2022-10-17)Diese Arbeit stellt die Ligandenfeldanalyse von Samarium(III)- und Europium(III)-oxoverbindungen, sowie von Samarium(III)- und Europium(III)-fluorid vor. Die Ligandenfeldanalysen wurden im Rahmen des Angular Overlap Model ... -
Light Propagation in Digital Material Structures
Velinov, Zdravko (2019-03-26)Light takes many paths throughout the physical environment, defined by a multitude of interactions with matter, before reaching an imaging sensor or the human eye and thus forming the visual perception of the world. ... -
A light-dependent aptamer-photoreceptor system enables spatiotemporal control of RNA biochemistry
Weber, Anna Maria (2022-07-29)Light plays an important role in all kingdoms of life and regulates processes such as plant growth, flowering or vision in complex life forms. The growing field of optogenetics harnesses those properties by combining them ... -
Light-trapping and Superhydrophobic Plant Surfaces: Optimized Multifunctional Biomimetic Surfaces for Solar Cells
Schulte, Anna Julia (2012-09-21)In a process spanning over 400 millions years of evolution, plants have developed multifunctional surfaces that are highly adapted to environmental conditions. Nature provides several millions varieties of plant species ... -
Limitation of body mass of herbivores: Allometry of food quality and of digestive aspects
Steuer, Patrick (2010-10-13)That the length of digesta passage rate of large herbivores was influenced by the BM of the animal was discussed controversial in the past and recently. However, recent studies with increasing data sets show tendencies to ... -
Limiting Properties of a Continuous Local Mean-Field Interacting Spin System: Hydrodynamic Limit, Propagation of Chaos, Energy Landscape and Large Deviations
Müller, Patrick Erich (2016-08-29)A key interest in the study of interacting spin systems is the rigorous analysis of the macroscopic dynamical behaviour of systems that are described by their microscopic evolution. In this dissertation, we investigate ... -
Lineage Selection and Enhanced Tissue Integration of Functional and Cryopreservable Human Embryonic Stem Cell-Derived Neurons
Ladewig, Julia (2009-05-13)In this study, a human Doublecortin (DCX) promoter-based lineage selection strategy is presented for the generation of purified human embryonic stem (hES) cell-derived immature neurons. Stable transfection of long-term ... -
Lineage-Selektion und Transplantation ES Zell-abgeleiteter neuraler Vorläuferzellen
Schmandt, Tanja (2004)Embryonale Stammzellen (ES Zellen) besitzen drei einzigartige Fähigkeiten, die sie als Spenderquelle für Zellersatzstrategien im Zentralnervensystem sehr attraktiv erscheinen lassen: sie sind pluripotent, ... -
Linear Inviscid Damping for Monotone Shear Flows, Boundary Effects and Sharp Sobolev Regularity
Zillinger, Christian (2015-07-23)In this thesis, we study the linear stability and long-time asymptotic behavior of solutions to the 2D incompressible Euler equations, which model the evolution of an inviscid, incompressible fluid.
The Euler equations ... -
Linearly polarised photon beams at the BGO-OD experiment at ELSA
Bella, Andreas (2016-11-04)The BGO-OD experiment, located at the electron stretcher facility ELSA in Bonn, is constructed for the study of meson photo-production reactions off the nucleon. The two main detector parts of the experimental setup are a ... -
