Fluctuations and dissipation in a Bose-Einstein condensed photon gas
Öztürk, Fahri Emre (2021-12-02)Bose-Einstein condensation, superfluidity and superconductivity are all related phenomena where particles behave as collective quantum systems. The behavior of such systems is treated using quantum statistics and their ... -
Fluid Density Approximation for an Implicit Solvent Model
Jager, Lukas (2007)The microscopic simulation of molecules in solution is a highly challenging task. An explicit simulation of the entire solute-solvent system is often unfeasible due to the high number of degrees of freedom necessary in ... -
Fluid driven processes in the crust – the formation of anorthositic dykes in the Troodos ophiolite (Cyprus)
Zirner, Aurelia Lucretia Katharina (2017-10-12)Anorthositic dykes related with the Upper Cretaceous Troodos ophiolite are described for the first time. An entire anorthosite dyke swarm appears within the Limassol Forest Complex, crosscutting the supply channels of late ... -
Fluorescence-based systems for detection of abiotic stresses on horticultural crops
Kautz, Burkard (2016-05-10)The main objective of this thesis was to assess the impact of economically important abiotic stresses on the plant physiology using non-destructive fluorescence indices, and to evaluate the potential use of the sensor ... -
Fluorescent proteins for two-photon FLIM analysis of presynaptic protein interactions
Gulakova, Polina (2020-06-10)Monitoring Förster Resonance Energy Transfer (FRET) between fluorescent proteins (FPs) fused to proteins of interest is a powerful approach to study dynamic interactions of cellular proteins in living cells. The choice of ... -
Fluoreszenzmarker der hochauflösenden Einzelmolekülmikroskopie: Entwicklung einer Quantum-Dot-Sonde und Charakterisierung organischer Fluorophore in vitro und in vivo
Schmitz-Ziffels, Ulrike (2013-11-19)In eukaryontischen Zellen findet der Stoffaustausch zwischen Zellkern und Cytoplasma über die in die Zellkernmembran eingebetteten Kernporenkomplexe statt. Makromoleküle können die Pore nur passieren, wenn sie einen ... -
Fluoreszenzoptische Kariesdetektion bei restaurierten Zähnen
Wilde, Claudia (2013-07-24)Ziel der Studie war es, die Eignung eines fluoreszenzoptischen Systems bezüglich der Entdeckung von Sekundärkaries bei Composit- und Amalgamfüllungen zu prüfen.<br /> 32 extrahierte menschliche gefüllte Zähne wurden nach ... -
Fluoreszenzoptische Untersuchung an versiegelten Zähnen
Gaitzsch, Claudia Yvonne (2013-07-18)Eine tägliche Herausforderung in der zahnärztlichen Praxis stellt die Kariesdiagnostik dar. Speziell an konservierend oder prophylaktisch mit Composite vorbehandelten Zähnen ist eine kariöse Läsion schwierig zu erkennen. ... -
Fluorine-18 labeling and simultaneous glycosylation of the model peptide demobesin 1 by the novel prosthetic group, keto-[18F]FDG
Thapa, Uttam (2014-07-23)With the development of keto-[<sup>18</sup>F]FDG in this work a new powerful prosthetic group for labeling of carbonyl reactive compounds has been added to the tools available for labeling biomelecules with the radionuclide ... -
Fluorooxoanionen vierwertigen Schwefels und Tellurs
Keßler, Ulrich (2001)Der Kenntnisstand über die Fluoridoxide von vierwertigem Schwefel, Selen und Tellur war bisher gering, Strukturinformationen wurden fast ausschließlich über die Interpretation von Schwingungsspektren erhalten. Die erste ... -
Fluorophordesign und Fluoreszenzmarkierung: Synthese funktionalisierter BODIPY-Derivate und Markierung von Purinrezeptor-Liganden
Freudenthal, Sven Jan (2002)Adenosine receptors are G-protein-coupled receptors present in the cell membranes of many organs and tissues. Four different subtypes are known to date (A<sub>1</sub>, A<sub>2A</sub>, A<sub>2B</sub>, A<sub>3</sub>). ... -
Flux Density and VLBI Measurements of the IDV Source 0917+624
Bernhart, Simone (2010-03-29)Extragalactic compact flat spectrum radio sources are known to be highly variable and about 30% of them show intra-day variability (IDV). The quasar 0917+624 was known to show prominent IDV behaviour from the time it was ... -
Fluß- und Talgeschichte im Raum Marburg: Eine geomorphologische Studie
Heine, Klaus (1970)Der Raum um Marburg an der Lahn hat in der jüngsten Zeit keine morphologische Bearbeitung erfahren. Mit der vorliegenden Untersuchung wird beabsichtigt, eine genaue Rekonstruktion der Fluß- und Talgeschichte - räumlich wie ... -
Der flüssige Ferromagnet – Magneto-optische Messungen
Stefan, Lucian Marius (2005)Der Existenz magnetischer Ordnung in einer Flüssigkeit steht theoretisch nichts entgegen. In der Natur begegnet man dieser aber nicht, denn die magnetische Übergangstemperatur – die sogenannte Curie-Temperatur - liegt bei ... -
Fog Collection on Plant Surfaces and Biomimetic Applications
Azad, Md. Abul Kalam (2016-06-23)Shortages of fresh water affect around one billion people world-wide; mostly in arid and semi-arid climates. Fog, in certain regions, may be an important source of water that is often overlooked. Inspired by the distinctive ... -
