The plesiosaur: remarkable morphology, histology, and physiology
Wintrich, Tanja (2019-07-04)In this dissertation, contributions to understanding the morphology, histology, and physiology of plesiosaurs, a major group of marine reptiles from the Age of Dinosaurs, are presented. By using comparative methods and new ... -
Pnictogenide and Chalcogenide Zintl Phases via Solid State and Solvothermal Syntheses
Hermann, Frederik Simon (2022-09-08)This work concentrated on the synthesis of new Zintl phases, especially focusing on the synthesis of new polyarsenides and chalcogenides. Through high temperature synthesis, the compounds Ba3As4, Ba3As2O and K3Ba7(As3)3O ... -
Pointwise convergence, maximal functions and regularity issues in harmonic analysis
Gonçalves Ramos, João Pedro (2020-03-05)This cumulative thesis is dedicated to the study of different maximal operators related to pointwise convergence in Fourier Analysis and is divided in three main parts.
The first part is dedicated to regularity results ... -
Polar Auxin Transport And Auxin Induced Development: Root System And Signaling Molecules Give The Clue
Schlicht, Markus (2008)Nearly every developmental phase and every growth process of a plant is affected by auxin. Auxin is transported over long distance via the phloem but also polarly from cell-to-cell, along the entire plant body; from the ...

Polare und schalenförmige molekulare Speichenräder
Kersten, Maximilian (2022-05-16)Ziel dieser Arbeit war zum einen die Synthese eines polaren amphiphilen Phenylen-basierten molekularen Speichenrades (MSWs) mit geringerer Symmetrie. Die Amphiphilie soll durch die Einführung von Pyridylgruppen erreicht ... -
PolKa: a Polarimeter for Submillimeter Bolometer Arrays
Siringo, Giorgio (2003)Starting from measurements of the linear polarization of the radiation emitted by celestial objects it is possible to estimate some physical parameters of the source. For example, magnetic field intensities and directions ... -
Polymerpartikel zur ektoparasitären Anwendung am Tier
Selbach, Claudia (2010-07-15)Parasiten beim Haustier sind nicht nur unangenehm, sondern vielmehr auch Überträger gefährlicher Krankheiten. Ein effizienter und lang anhaltender Schutz ist daher wünschenswert. Ziel dieser Arbeit war es, ein Formulierungskonzept ... -
Polynomial Inflation and Its Aftermath
Xu, Yong (2022-11-10)Cosmic inflation elegantly resolves problems in the standard cosmology. The most simple inflationary theory invokes a single scalar field phi, slowly rolling down from a flat potential of a monomial form. However latest ... -
Population Pharmacokinetic and Pharmacodynamic Modelling and Simulation of Linagliptin, a Novel Dipeptidyl-Peptidase 4 Inhibitor for the Treatment of Type 2 Diabetes
Retlich, Silke (2010-09-21)Linaglipin is a novel dipeptidyl-peptidase 4 (DPP-4) inhibitor in clinical development for the treatment of type 2 diabetes. This thesis investigated the nonlinear pharmacokinetics of linagliptin as well as the relationship ... -
Population pharmacokinetic modeling to understand antineoplastic treatment
Arshad, Usman (2020-06-29)Introduction: The pronounced variability in pharmacokinetics of antineoplastic drugs caused by known and unknown sources translates into variability in therapeutic outcome. This is a major concern for these ... -
Pore-Scale Modelling of Induced-Polarization Mechanisms in Geologic Materials
Bücker, Matthias Benedikt (2019-03-20)This thesis is concerned with mechanistic pore-scale models, which relate the induced-polarization (IP) response of geologic materials to the underlying physical and chemical processes. Although a sound understanding of ... -
Positronenspektroskopie an Ermüdungsrissen und Spanwurzeln
Haaks, Mathias (2003)Seit den 60er Jahren des vorigen Jahrhunderts werden Positronen zur Untersuchung von Festkörpern eingesetzt. Die Zerstrahlungsparameter von Positron und Elektron sind dabei sensitiv auf Art und Konzentration von Gitterdefekten ... -
Positronenspektroskopie an plastischen Zonen in Al-Legierungen und GaAs-Wafern
Zamponi, Christiane (2002)In dieser Arbeit wurden Defekte, die durch mechanische Deformation in Aluminiumlegierungen bzw. in GaAs-Wafern erzeugt wurden, mit der Methode der Positronenannihilations-Spektroskopie untersucht. Für diese Messungen stand ... -
Posttranslational modifications of Ancient Ubiquitous Protein 1 control intracellular Lipid Droplet clustering
Lohmann, Daniel (2013-05-15)Lipid droplets (LDs) are the intracellular storage organelles for neutral lipids. Over the last decade LDs have been identified to play important roles in lipid homeostasis, cellular signaling events and as a platform to ... -
Potential of Complementary Methods for the Authentication of Herbal Substances and their Mixtures
Doganay-Knapp, Kirsten (2015-10-22)Herbal substances and preparations thereof play an important role in healthcare systems worldwide. An essential prerequisite for the safe and effective use of herbal medicines is the unequivocal identification of the plant ... -
