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
Bashiri, Kaveh (2020-06-19)Many stochastic models exhibit a phenomenon called metastability. The first goal of this thesis is to study this phenomenon for certain classes of interacting particle systems. The second goal of this thesis is the following. ... -
Grained integers and applications to cryptography
Loebenberger, Daniel (2012-05-24)To meet the requirements of the modern communication society, cryptographic techniques are of central importance. In modern cryptography, we try to build cryptographic primitives, whose security can be reduced to solving ... -
Grand Unification in the Heterotic Brane World
Vaudrevange, Patrick Karl Simon (2008)<p>String theory is known to be one of the most promising candidates for a unifed description of all elementary particles and their interactions. Starting from the ten-dimensional heterotic string, we study its compactification ... -
Grand-Design Warps in Galactic Disks
Józsa, Gyula István Géza (2006)Warping, a bending of the disk, is present in all disk galaxies. It is hence a phenomenon that should not be missed to be explained in theories of galactic evolution and formation. Warps usually occur at radii where the ... -
Granulares Modell zur Simulation der Ermüdung von Metallen
Fingerhuth, Judith (2010-01-27)Materialermüdung ist im Alltag der Menschen und durch die entstehenden Kosten für die Wirtschaft ein Problem. Als Alternative zum bisher zur Abschätzung der Lebensdauer verwendeten material- und zeitintensiven Wöhler-Verfahren ... -
Graphical Models and Symmetries: Loopy Belief Propagation Approaches
Ahmadi, Babak (2014-08-29)Whenever a person or an automated system has to reason in uncertain domains, probability theory is necessary. Probabilistic graphical models allow us to build statistical models that capture complex dependencies between ... -
Gravitrope Genexpression in Helianthus annuus
Theisen, Ralf (2005)An der Weiterleitung des gravitropen Stimulus vom Rezeptor bis zum Wirkungsort innerhalb einer höheren Pflanze (Helianthus annuus L., Sonnenblume) sind zahlreiche Signaltransduktions-Schritte beteiligt, die nur zum Teil ... -
Gravity Tests with Pulsars Using New-Generation Radio Telescopes
Hu, Huanchen (2023-05-23)Pulsar timing is a powerful tool for studying a wide range of questions in fundamental physics, including the equation of state (EOS) of super-dense matter, tests of general relativity (GR) and alternative theories of ... -
Gravity-sensing processes and gravity-dependent gene expression in plants: studied under altered gravity conditions
Vagt, Nicole (2010-11-05)The present study focused on the cellular and molecular gravisensing-related processes in Arabidopsis and in the unicellular rhizoids of the green alga Chara. Experiments during sounding-rocket and parabolic plane flights ... -
Grenzen und Möglichkeiten von Naturrisikomanagement: Ein systemtheoretischer Ansatz
Danscheid, Marco (2010-05-28)Naturrisiken werden seit einigen Jahren ein zunehmend wichtiges Thema. Das Erdbeben vom 12. Mai 2008 in der chinesischen Provinz Sichuan forderte 20.000 Tote allein durch erdbebenversursachte Hangrutschungen – eine kaum ... -
Grenzen virtueller Vernetzung in der Automobilindustrie: Einflüsse elektronischer Marktplätze auf Zuliefer-Abnehmer-Beziehungen
Schlösser, Oliver (2005)Zuliefer-Abnehmer-Beziehungen gewinnen im Zusammenhang mit fortwährenden Outsourcing-Prozessen seit Mitte der 1990er Jahre an Bedeutung, da sie die Wettbewerbsfähigkeit von Unternehmen in gesteigertem Maße beeinflussen. ... -
Gromov-Witten correspondences, derived categories, and Frobenius manifolds
Smirnov, Maxim (2013-02-21)In this thesis we consider questions arising in Gromov-Witten theory, quantum cohomology and mirror symmetry. The first two chapters deal with Gromov-Witten theory and derived categories for moduli spaces of stable curves ... -
Growing lake with growing problems: integrated hydrogeological investigation on Lake Beseka, Ethiopia
Belay, Eleni Ayalew (2009-02-03)The complex tectonic and volcanic processes in the Ethiopian rift valley have resulted in the formation of volcano-tectonic structural depressions that became sites for many rift valley lakes. Lake Beseka is one of the ... -
