Paraglacial Sediment Storage Quantification in the Turtmann Valley, Swiss Alps
Otto, Jan Christoph (2009)The determination of sediment storage is a critical parameter in sediment Budget analyses. Sediment Budgets link sediment dynamics to landform evolution; the analysis of spatial landform distriBution can support the ... -
Parallel activation of different word forms – investigation of speech production by means of associates
Groten, Nina (2008)<p>The parallel activation of different word forms is a central topic in the discussion about different models of speech production. Several experiments were conducted in the scope of this dissertation. A new method, ... -
Parallel RBF Kernel-Based Stochastic Collocation for Large-Scale Random PDEs
Zaspel, Peter (2015-07-03)In this thesis, the solution of large-scale uncertainty quantification problems is considered. Uncertainty quantification aims to extract stochastic (moment) information from processes with uncertain input data. These ... -
Parallele und individuelle Evolution des Humanen Immunodefizienz Virus 1 Glykoprotein-Gens (env) nach klonaler Infektion von fünf hämophilen Patienten
Kurz, Ralf (2009-11-25)Hämophilie B mit einem genetisch identischen HIV-1 Stamm konnte die Virusevolution des HIV-1 Glykoprotein kodierenden env-Gens und im Speziellen der V2-Region über einen Zeitraum von zehn Jahren untersucht und in Korrelation ... -
Parameters Associated with the Required Drug Dose of Intravenous Immunoglobulin in Stable Chronic Inflammatory Demyelinating Polyradiculoneuropathy
Feyen, Ludger; Schaub, Christina; Zimmermann, Julian; Nitsch, Louisa (2023-03-10)Background: Intravenous immunoglobulin (IVIg) is efficient and one of very few treatment options for patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). However, finding the optimal dose of ... -
Parametric excitation of the quantum vacuum in nonlinear optical resonators
Langerfeld, Thorsten Friedrich (2022-07-25)In this thesis, I present the generation of correlated photon pairs in high-finesse nonlinear optical micro-resonators. In a first attempt, we utilize the third-order nonlinear material polarization of the dielectric mirror ... -
Parametric Model Order Reduction Using Sparse Grids
Brunsch, Sina (2017-09-29)In applications such as very large scale integration chip design models are typically huge. The same is true in mechanical engineering, especially when the models are complex finite element discretizations. To speed up ... -
Paris - Raum und Zeichen einer Stadt
Kunkel, Stefanie (2018-06-04)In der Kombination raumtheoretischer Aspekte mit solchen der Semiotik, die bei einer Auseinandersetzung mit raumtheoretischen Konzepten im Umfeld des <em>spatial turns</em> und insbesondere mit einer Fokussierung auf den ... -
The Parkinson’s disease-related kinase Pink1 mediates mitochondrial quality control
Rüb, Cornelia (2016-08-29)Mitochondrial dysfunction is a common feature of many neurodegenerative diseases, in particular Parkinson’s disease (PD). Mutations in the genes encoding the mitochondrial kinase Pink1 and the cytosolic E3 ubiquitin ligase ... -
Paroxysmales Vorhofflimmern bei Schrittmacherpatienten: Einfluss präventiver Stimulationsalgorithmen auf das Verteilungsmuster der Induktionsszenarien
Kruse, Susanne Maria (2010-07-08)Beim Vorhofflimmern handelt es sich um die häufigste anhaltende Rhythmusstörung des Herzens. Ziel vieler Studien war es, Vorhofflimmern durch präventive Stimulation mittels Schrittmacher zu verhindern. <br /> Folgende ... -
Participation of Ste20-like kinase-deficient neurons in the abnormal circuitry of focal epileptogenic lesions
Royero Rodriguez, Pedro Xavier (2022-01-03)Focal epileptogenic lesions displaying morphologically altered neurons are frequently associated with devastating and therapy-refractory epilepsies. However, it is still unsolved how dysplastic neurons contribute to the ... -
A participatory multi-criteria approach for flood vulnerability assessment
Madruga de Brito, Mariana (2018-09-14)The management of flood risk calls for a better understanding of vulnerability, as hazards only become disasters if they impact a system that is vulnerable to their effects. Although different frameworks have been proposed ... -
Particle engineered inhalable dry powders of rifampicin
Berkenfeld, Kai Wilfried August (2019-12-12)Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. Main site of infection are the lungs, but infection of other organs can occur in later stages. First line therapy includes antibiotic therapy ... -
Particle engineering for high dose dry powder inhalation of itraconazole
Willmann, Ann-Cathrin (2022-12-05)Itraconazole (ITZ) is considered as first-line therapy against respiratory infections such as allergic bronchopulmonary aspergillosis. Local treatment of these infections is regarded beneficial as it might reduce systemic ... -
Particle Physics from Singular Geometries
Oehlmann, Paul-Konstantin (2016-02-16)We study string compactifications on spaces that are either partial or fully singular and analyze the symmetries in the effective theories that they generically give rise to. In the heterotic case we consider orbifolds and ... -
Partitioning of carbon dioxide exchange in rapidly and slowly changing ecosystems
Ney, Patrizia (2019-11-07)Im Hinblick auf den aktuellen Klimawandel besteht die Frage, wie die Biosphäre auf den Globalen Wandel und die daraus hervorgehende lokale Landnutzungsänderung bezüglich ihres Kohlenstoffkreislaufes reagiert. Die Landoberfläche ... -
Partitioning Water Vapor Fluxes by the Use of Their Water Stable Isotopologues: From the Lab to the Field
Quade, Maria Elisabeth (2019-09-04)Water stable isotopes are powerful tracers for partitioning of the terrestrial ecosystem water vapor fluxes into process-based components, i.e. evapotranspiration (<em>ET</em>) into soil evaporation (<em>E</em>) and plant ... -
Pastoral Practices, Economics, and Institutions of Sustainable Rangeland Management in Kenya
Kihiu, Evelyne Nyathira (2016-04-08)Rangelands contribute greater value than is generally acknowledged. The ecosystems provide a significant portion of the world’s biodiversity and culturally diverse habitats and are also of great ecological and economic ... -
