Platelet-immune cell interactions in inflammation and cancer
(2019-09-10)Platelets are well-known for their role in hemostasis and only more recently, they have also been acknowledged for their immune regulatory roles. Despite being small sized and anucleated, they can respond to inflammatory ... -
The plesiosaur: remarkable morphology, histology, and physiology
(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
(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
(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.<br /> The first part is dedicated to regularity results ... -
Polar Auxin Transport And Auxin Induced Development: Root System And Signaling Molecules Give The Clue
(2008)<p>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
(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
(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 ... -
Polymer-mediated solubility enhancement and supersaturation stabilization using various hydroxypropyl cellulose grades within amorphous solid dispersions
(2024-05-14)Solubility enhancement in combination with supersaturation stabilization of poorly soluble drugs is a well-established concept to enhance oral bioavailability. One promising formulation principle to overcome low solubility ... -
Polymerpartikel zur ektoparasitären Anwendung am Tier
(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
(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 ... -
Poplars, apoplastic barriers, and the environment
(2024-09-02)This doctoral thesis, “Poplars, apoplastic barriers, and the environment”, is dedicated to the ecophysiological traits of poplars, especially their apoplastic barriers in roots and leaves, in the scope of environmental ... -
Population Pharmacokinetic and Pharmacodynamic Modelling and Simulation of Linagliptin, a Novel Dipeptidyl-Peptidase 4 Inhibitor for the Treatment of Type 2 Diabetes
(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
(2020-06-29)<strong>Introduction:</strong> 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
(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
(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
(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
(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 ... -
