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 ... -
Polymer-mediated solubility enhancement and supersaturation stabilization using various hydroxypropyl cellulose grades within amorphous solid dispersions
Pöstges, Florian (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
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 ... -
Poplars, apoplastic barriers, and the environment
Grünhofer, Paul David (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
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)<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
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 ... -
Potenziale quantitativer Landschaftsanalysen als Monitoring-Instrument im Gebietsnaturschutz: Untersuchungen am Beispiel des Biosphärenreservats Rhön
Nienkemper, Pamela (2017-08-25)Im Kontext des Monitorings im Gebietsnaturschutz treten bei der Quantifizierung von Land-schaftsveränderungen auf Basis kategorialer Daten unterschiedliche methodische und inhalt-liche Probleme auf, die in der Arbeit am ... -
A Potpourri of Partition Properties
Weinert, Thilo Volker (2014-08-06)The cardinal characteristic inequality r <= hm3 is proved. Several partition relations for ordinals and one for countable scattered types are given. Moreover partition relations for lexicographically ordered sequences of ... -
Powering Accra: Projecting Electricity Demand for Ghana‘s Capital City
Frazier, Tyler James (2011-08-05)The purpose of this research was to create an agent-based urban simulation based on land use at the plot level for projecting the disaggregated electricity demand of the Greater Accra Metropolitan Area (GAMA). A simulation ... -
PPARγ in myeloid cells controls CNS autoimmunity
Hucke, Stephanie (2012-03-12)The nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-activated transcription factor that regulates the immunogenicity of myeloid cells such as dendritic cells (DCs), macrophages, and ... -
