The fate of a recessive allele in a Mendelian diploid model
Ströfer, Rebecca Sarah (2017-08-23)The omnipresence of sexual reproduction in a highly competitive world is a fascinating phenomenon. Its evolution and maintenance is up to now not completely understood since it is known that sexual reproduction require ... -
Fault Roughness and Fault Complexity: Field Study, Multi-Scale Analysis and Numerical Fault Model
Navarro, Martin (2002)We study the roughness of normal faults in lignite and its relevance to the complex process of faulting by means of field observations and a numerical model for wear at rough fault surfaces. Roughness data is collected at ... -
Faunal Provinces and Patterns of Diversity in Late Cretaceous (Santonian-Maastrichtian) Larger Foraminifera
Goldbeck, Elke J. (2008)A detailed biogeographical analysis of the global distribution of 25 different genera of larger symbiont-bearing foraminifera from the Late Cretaceous reveals that they exhibit distinct patterns. On a generic level, the ... -
Fälschungen pflanzlicher Arzneimittel, Lebensmittel und Kosmetika: Regulierung von Arzneimitteln und Lebensmitteln im Hinblick auf die Fälschungssicherheit von pflanzlichen Produkten
Müller, Iris Annette (2015-11-18)Pflanzliche Arzneimittel, Medizinprodukte und Lebensmittel oder Kosmetika werden von immer mehr gesundheits- und umweltbewussten Patienten verwendet. Auf der anderen Seite nimmt die Zahl von Arzneimittelfälschungen und ... -
Feasibility and Efficacy of a Collaborative Medication Management for Elderly, Multimorbid Patients
Rose, Olaf (2017-08-29)Medication Review and Medication Management are new pharmaceutical care services with a strong potential to contribute to patients’ health care outcomes. The aim of this work was to evaluate an interprofessional, collaborative ... -
Federated Query Processing over Heterogeneous Data Sources in a Semantic Data Lake
Endris, Kemele M. (2020-05-05)Data provides the basis for emerging scientific and interdisciplinary data-centric applications with the potential of improving the quality of life for citizens. Big Data plays an important role in promoting both manufacturing ... -
Femtosekunden-Infrarot-Spektroskopie von dreiatomigen Pseudohalogenid-Ionen sowie organischen und anorganischen Pseudohalogenid-Verbindungen
Czurlok, Denis (2016-01-20)Die charakteristische, starke Resonanz dreiatomiger Pseudohalogenide im Frequenzbereich von 2000 cm<sup>-1</sup> wurde als spektrale Sonde verwendet, um ultraschnelle Vorgänge in kondensierter Materie aufzuklären. Dazu ... -
Fermat Reals: Nilpotent Infinitesimals and Infinite Dimensional Spaces
Giordano, Paolo (2010-01-20)The main aim of the present work is to start a new theory of actual infinitesimals, called theory of Fermat reals. After the work of A. Robinson on nonstandard analysis (NSA), several theories of infinitesimals have been ... -
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 ... -

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
