Global change effects on ecosystem species composition, functions and services of West Africa’s Sudanian savannas
Guuroh, Reginald Tang (2016-12-09)Savanna ecosystems cover an eighth of the world's land surface and are of immense ecological and economic importance. Ecologically, they help regulate climate, air quality, water quality, and soil erosion. Economically, ... -
Global Existence Without Decay
Schottdorf, Tobias (2013-12-05)We treat some problems related to the small data global existence theory of some dispersive PDEs. That is, we try to abstractly construct solutions which exist globally in time and have “good” properties, under a smallness ... -
Global homotopy theory via partially lax limits
Linskens, Sil (2024-09-16)Global equivariant homotopy theory is often motivated as the study of compatible collections of equivariant objects for some family of compact Lie groups. In this thesis we make this heuristic precise, by exhibiting the ... -
Global Modelling of Atmospheric Halogen Chemistry in the Marine Boundary Layer
Kerkweg, Astrid (2005)The importance of reactive halogen chemistry in our atmosphere has become evident throughout the last decades. The discovery of the chemical reactions leading to the stratospheric ozone hole over the South Pole in spring ... -
Global Modelling of Cloud, Convection and Precipitation Influences on Trace Gases and Aerosols
Tost, Holger (2006)In atmospheric chemistry modelling increasing attention has been paid to the effects of aqueous phase chemistry in the last decade. Even though wet deposition is a considerable sink in the atmospheric budgets of several ... -
Global Timing Optimization in Chip Design
Daboul, Siad (2021-04-12)In this thesis, we aim at solving the interconnect optimization problem comprehensively. By balancing global timing, routing, placement, and power constraints in a global model, we obtain solutions which outperform the ... -
Global-Local Techniques for Fracture
Birner, Matthias (2023-12-20)In the numerical simulation of components and structures it is necessary to incorporate the effect of localized damage and its propagation. However, simulating fracture on top of linear elasticity in three space dimensions ... -
Globale und lokale Optimierungsverfahren für dreidimensionale Anordnungsprobleme
Schäfer, Mike (2002)Thema dieser Arbeit sind <i>Optimierungsverfahren zur Anordnung dreidimensionaler, polyonaler Objekte</i>. Zielkriterium ist die möglichst dichte Packung der Objekte unter Berücksichtigung vorgegebener Randbedingungen. <br ... -
GLOSTAR: Investigating Tracers of Early High-Mass Star Formation
Nguyen, Hans Vietviet (2023-05-12)High-mass stars (>8 msol) are not as numerous as their less massive counterparts but have a much more profound impact on their environment within their native galaxies. Despite their importance, our understanding of their ... -
Glucuronidierung von Paracetamol durch menschliche Lebermikrosomen in vitro: Enzymkinetische Parameter und Einflüsse von kurzkettigen aliphatischen Alkoholen sowie von Opiaten
Boldt, Petra (2006)Die Glucuronidierung ist ein wichtiger Metabolisierungsschritt im menschlichen Organismus für viele Arzneistoffe, Drogen und körpereigene Stoffwechselprodukte. Durch verschiedene Glucuronyltransferasen in den Lebermikrosomen ... -
Gluing of metric measure spaces and the heat equation with homogeneous Dirichlet boundary values
Profeta, Angelo (2020-07-09)The first part of this thesis deals with gluing together several copies of an open subset of a metric measure space along the complement. This construction results in a metric measure space. We identify the Cheeger energy ... -
Gluing Spaces and Analysis
Paulik, Gustav (2005)In the first part of this work we study the gluing of metric measure spaces. The gluing is defined by a bilipschitz map which identifies the gluing sets. The new metric is given by the minimal length of all possible paths ... -
Glykosylierungsstellen-spezifische Analytik der Oligosaccharide rekombinant hergestellter humaner Arylsulfatase A, produziert in verschiedenen Zelllinien
Schröder, Stephan (2008)<p>Die Ergebnisse der vorliegenden Arbeit zeigen, dass die Oligosaccharidseitenketten der drei N-Glykosylierungsstellen der hASA unterschiedlich strukturiert sind. Die Oligosaccharidstrukturen sind überwiegend vom ... -
Gold-Tellurium Clusters and Tetrachloridoaurates with Divalent Cations
Landvogt, Christian Rudolf (2017-04-19)The solid state reaction of AuX<sub>3</sub>, Te and a Lewis-acidic metal halide results in a series of compounds containing the new cationic gold-tellurium cluster (Au<sub>6</sub>Te<sub>18</sub>X<sub>n</sub>)<sup>(6-n)+</sup>. ... -
The governmental and non-governmental approaches to maintain medium and long-term disaster resilience after a mega-disaster: Case study: Aceh Province, Indonesia after 2004 the Indian Ocean Tsunami
Sari, Siswani (2019-07-30)After the Indian Ocean Tsunami in 2004, the Government of Aceh started to promote disaster risk reduction and to build disaster resilience in order to address the current challenges in disaster risk mitigation in Aceh ... -
GPR183 controls spatial organization and survival of hepatic conventional dendritic cells within hepatic portal regions via M-CSF and Gas6
Sheoran, Sumit (2023-04-19)G protein-coupled receptor 183 (GPR183) recognizes 7α,25-dihydroxycholesterol (7α,25-OHC) and exerts chemotactic action upon recognition. Recent studies have shown that GPR183 is highly expressed in T, B and dendritic cells ... -
GPR183 Expression on Pulmonary Conventional Dendritic Cell Type 2 Dictates Subtissular Localisation and Instructs Their Survival via the Thymic Stromal Lymphopoietin (TSLP) – TSLP Receptor (TSLPR) Axis
Zhang, Lili (2021-07-06)Introduction: G protein-coupled receptor 183 (GPR183) is a chemotactic receptor, highly expressed by immune cells. Upon activation by its ligand, 7a,25-dihydroxycholesterol (7a,25-OHC), GPR183 activates downstream signals ... -
The gradient flow of the double well potential and its appearance in interacting particle systems
Geldhauser, Carina (2016-10-13)In this work we are interested in the existence of solutions to parabolic partial differential equations associated to gradient flows which involve the so-called double well potential, which is a nonconvex and nonconcave ... -
Gradient Flows, Metastability and Interacting Particle Systems
