Fernerkundungsgestützte Modellierung kleinräumiger Biodiversität am Beispiel des Turtmanntals in der Schweiz
Kleinod, Konstanze (2008)Hochgebirge sind Regionen mit extrem hoher Biodiversität. Sie erschließen die dritte Dimension, das heißt sie enthalten eine vertikale Klimazonierung auf sehr kurzer Distanz, was zu einer Komprimierung der Vegetationszonen ... -
Ferredoxin-dependent electron transport during methanogenesis from acetate
Welte, Cornelia (2011-09-12)Methanogenic archaea are one of the key groups in global carbon turnover. They metabolize the conversion of the end products of the anaerobic food chain to methane. Of particular importance is the methanogenesis with acetate ... -
Ferromagnetic Semiconductor-Metal Transition in Europium Monoxide
Arnold, Michael (2007)We present a microscopical model to describe the simultaneous parato- ferromagnetic and semiconductor-to-metal transition in electrondoped EuO. The physical properties of the model are systematically studied, whereas the ... -
Ferromagnetic Semiconductor-Metal Transition in Heterostructures of Electron Doped Europium Monoxide
Stollenwerk, Tobias (2013-10-17)In the present work, we develop and solve a self-consistent theory for the description of the simultaneous ferromagnetic semiconductor-metal transition in electron doped Europium monoxide. We investigate two different types ... -
Feste Lösungen aus amorpher Stärke
Wauer, Gabriel Friedrich (2010-11-10)In dieser Arbeit wurde die Herstellung amorpher Stärke-Tramadol*HCl-Extrudate an einem Einschneckenextruder und Zweischneckenextruder untersucht, die Produkte gelagert und analysiert. Einflußfaktoren wie Feuchte, Wirkstoffart, ... -
Fettsäure-unabhängige Anpassung bakterieller Membranen an niedrige Temperaturen
Seel, Waldemar (2020-07-01)Nach dem bisherigen Kenntnisstand der Forschung erfolgt die Kälteadaptation der bakteriellen Zellmembran durch die Änderung der Fettsäurezusammensetzung. In dieser Arbeit wurden Lebensmittel-assoziierte Isolate, deren ... -
Few-body physics in a Finite Volume
Kreuzer, Simon (2010-11-03)In this work, three-body bound states were studied in finite volume using an Effective Field Theory framework. The finite volumes under consideration are cubic volumes with periodic boundary conditions. The Effective Field ... -
Few-Body Physics in Quantum Gases
Helfrich, Kerstin (2011-10-25)Few-body effects play an important role for the understanding of ultracold quantum gases. We make use of an effective field theory approach to investigate various aspects of universal few-body physics close to a Feshbach ... -
Few-Body Systems in a Shell-Model Approach
Tölle, Simon (2014-03-14)In this thesis, I introduce and compare an implementation of two different shell models for physical systems consisting of multiple identical bosons. <br /> In the main part, the shell model is used to study the energy ... -
Few-Body Systems in Lattice Effective Field Theory
Klein, Nico (2019-02-04)Nuclear lattice effective field theory is a novel approach in nuclear physics combining classical effective field theory with lattice methods and newly available computational resources. It is particularly successful for ... -
Fictive Impurity Approach to Dynamical Mean Field Theory
Fuhrmann, Andreas (2006)A new extension of the dynamical mean-field theory was investigated in the regime of large Coulomb repulsion. A number of physical quantities such as single-particle density of states, spin-spin correlation, internal energy ... -
Field observations and numerical simulations on the role of local structures and seismic source characteristics in the in uence of external earthquakes in volcanic and hydrothermal activity
Farías, Cristian (2016-02-10)Earthquakes can trigger volcanic and hydrothermal activity at a large distance range and a wide time window. While advances in observations in the last two decades have helped to establish that there exist a causal connection ... -
Filarial infection and filarial antigen administration promotes glucose tolerance in diet-induced obese mice
Berbudi, Afiat (2015-11-06)Excess of energy intake combined with reduced physical activity leads to accumulation and expansion of adipose tissue. Imbalance between adipose tissue expansion and oxygenation during a high fat diet results in adipocytes ... -
Filarial nematodes protect against malaria in a murine co-infection model
Fernández Ruiz, Daniel (2008)<p>Helminth infections such as filariasis can be life long due to immunomodulatory mechanisms elicited by the worms that prevent their elimination by the human host. Malaria prevalence is frequently high in areas where ... -
Final state interactions in strong two-body baryon decays
Morales Tolentino Zang, Daniela (2014-10-21)In the first part of this thesis, masses and strong decay widths of non-strange baryon resonances are described in the framework of a covariant quark model. The model is based on the solutions of the Bethe-Salpeter equation, ... -
Final-state interactions in heavy-meson decays
Niecknig, Johanna (2018-08-15)In the last decade the investigation of the heavy-meson sector has gained in importance, in particular for precision tests of the Standard Model and exploration of the physics beyond, such as CP violation. Experimentally, ... -
Finding Common Patterns In Heterogeneous Perturbation Data
Abnaof, Khalid (2016-05-24)This work investigates and proposes statistical analysis methods for pattern detection in high-throughput data from perturbation experiments in biology and medicine. This is demonstrated in three examples. <br /> The first ... -
Fine-Scaled 3D Geometry Recovery from Single RGB Images
Li, Jun (2018-01-04)3D geometry recovery from single RGB images is a highly ill-posed and inherently ambiguous problem, which has been a challenging research topic in computer vision for several decades. When fine-scaled 3D geometry is required, ... -
