L-Proline and Glutamatergic Neurotransmission: Clarifying the Modulatory Role of Neuronal L-Proline Transporter
Schulz, Daniel (2012-06-20)The neuronal high affinity L-proline transporter (PROT) is a putative neurotransmitter transporter whose contribution to neurotransmission is still unknown. PROT is expressed exclusively in brain by subpopulations of ... -
The L2-Torsion Polytope of Groups and the Integral Polytope Group
Funke, Florian (2018-01-24)This thesis contains three projects revolving around the L2-torsion polytope. First we show that the L2-torsion polytope of infinite elementary amenable groups vanishes. Then we establish a link between ... -
Laccasen und Laccasegene des acidophilen Ascomyceten Hortaea acidophila
Tetsch, Larissa (2005)Hortaea acidophila ist ein acidophiler Ascomycet der Ordnung Dothideales und bildet DHN-Melanin, an dessen Synthese u. a. Laccasen beteiligt sind. Bei diesen Enzymen handelt es sich um Polyphenoloxidasen mit vier ... -
Lagrangian field theories: ind/pro-approach and L∞-algebra of local observables
León Delgado, Néstor (2018-05-11)Field Theories in Physics can be formulated giving a local Lagrangian density. Locality is imposed using the infinite jet bundle. That bundle is viewed as a pro-finite dimensional smooth manifold and that point of view has ... -
Land-atmosphere interactions in multiscale regional climate change simulations over Europe
Knist, Sebastian (2018-12-12)Interactions between the heterogenous land surface and the atmosphere play a fundamental role in the weather and climate system through their influence on the energy and water cycles. Global climate models (GCMs) currently ... -
Landau-Zener-Stückelberg Interferometrie mit ultrakalten Atomen in Fouriersynthetisierten optischen Gitterpotentialen
Kling, Sebastian (2011-12-12)In dieser Arbeit werden Experimente zur Konstruktion eines Zweistrahl-Atominterferometers beschrieben. Für die Experimente wurde ein atomares Bose-Einstein Kondensat hergestellt und mit einem variablen bichromatischen ... -
A Landsat-based analysis of tropical forest dynamics in the Central Ecuadorian Amazon: Patterns and causes of deforestation and reforestation
Santos, Fabián (2018-12-20)Tropical deforestation constitutes a major threat to the Amazon rainforest. Monitoring forest dynamics is therefore necessary for sustainable management of forest resources in this region. However, cloudiness results in ... -
Landslide Hazard and Risk Assessment
Guzzetti, Fausto (2006)Landslides play an important role in the evolution of landforms and represent a serious hazard in many areas of the World. In places, fatalities and economic damage caused by landslides are larger than those caused by other ... -
Langerhans and inflammatory dendritic epidermal cells in atopic dermatitis tolerate Toll-like receptor 2-specific activation
Nümm, Tim Joachim (2021-01-26)Atopic dermatitis (AD) is a chronic multifactorial inflammatory skin disease. The skin of AD patients shows a significant dysbalance of the microbiome with high colonization of S. aureus, which positively correlates with ... -
Langzeitstudie (1987 – 1997) zur Biologie, Ökologie und Dynamik einer Steinkauzpopulation (Athene noctua SCOP. 1769) im Lebensraum der Mechernicher Voreifel
Zens, Karl-Wilhelm (2005)Die Arbeit untersucht die Situation des Steinkauzes (Athene noctua Scop. 1769) in der Mechernicher Voreifel. Hierzu wurden von 1987 bis 1997 innerhalb eines ca. 260 km² großen Gebietes (Kreise Euskirchen und Düren, NRW) ... -
Large scale in vivo recordings of dentate gyrus granule cells during trace eyeblink conditioning

The large-scale structure of the Universe; environmental effects and relativistic corrections
Borzyszkowski, Mikolaj Ryszard (2018-12-13)Over the cosmic age gravity has formed the structures in the universe where galaxies are part of. We study here the effect of the environmet on the formation of dark-matter haloes and find that the growth can be quenched. ... -
Laser Magnetic Resonance applied to excited States of Iodine and to the Fine structure Transition in the electronic Groundstate of Iodine Monoxide
Breitbach, Thomas H. (2002)This thesis describes an investigation of the spectra of iodine and iodine monoxide in the region about 2100cm-1. For this study, the CO Faraday Laser Magnetic Resonance Spectrometer at Bonn was used. For the first time a ... -
Laser Manipulation of Indium Atoms
dela Torre, Ruby (2005)This thesis presents experiments on laser cooling of an indium atomic beam. The long-term goal of this experiment is to deposit indium atoms on a substrate using a standing wave light mask. The atomic beam has to be initially ... -
Laval-Düsen als Zerstäuber für die inhalative Therapie
Fretter, Barbara (2007)Zerstäuber finden in der pharmazeutischen Technologie vielfache Anwendung mit unterschiedlichen Anforderungen an den Zerstäuber selbst und das entstehende Tropfengrößenspektrum. Basierend auf der Idee einen neuen Inhalator ... -
Learning Grasping and Walking Motion Generation for Humanoid Robots
Rodriguez Vargas, Diego Alexander (2021-04-30)For acting in human-made scenarios, humanoid robots are undoubtedly the most versatile and flexible platforms among a vast number of available robotic systems. However, this versatility comes at the cost of complexity. ... -
Learning Object Recognition and Object Class Segmentation with Deep Neural Networks on GPU
