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 ... -
Practical Models for Sequential Decision Making in Natural Language Processing and Reinforcement Learning
Ramamurthy, Rajkumar (2023-11-17)This thesis focuses on <em>sequential decision and prediction</em> (SDP) tasks, comprising structured prediction (SP) and reinforcement learning (RL) tasks. These tasks are characterized by generation of sequential outputs ... -
Präparative und theoretische Arbeiten zu Diphenylsubstituierten Phosphorverbindungen: Methylenphosphoniumion, Phosphinomethanid und para-funktionalisierte Triphenylphosphane
Boelsen, Christian Karl Georg (2002)Der formale Elektronentransfer auf ein Methylenphosphonium-Kation [>P=C<]<sup>+</sup>, führt zu einem Radikal und nachfolgend zu dem korrespondierenden Phosphinomethanid-Anion. Diese drei Spezies konnten durch eine geeignete ... -
Precision calculations for the low-energy dynamics of pions and nucleons
Hoferichter, Martin (2012-07-18)QCD is strongly coupled at long distances and therefore non-perturbative methods are required to understand its low-energy properties, e.g. to answer such basic questions as of the origin of the nucleon mass. In this thesis ... -
Precision Calculations in Supersymmetric Models using Phenomenological Tools
Nickel, Kilian (2016-12-21)We present a Higgs mass calculation at two-loop level based on the effective potential approach, which has been made available in the public computer codes SARAH and SPheno. The approach is based on generic formulae for ... -
Predicting Rules for Cancer Subtype Classification using Grammar-Based Genetic Programming on various Genomic Data Types
Deng, Mario (2018-03-12)With the advent of high-throughput methods more genomic data then ever has been generated during the past decade. As these technologies remain cost intensive and not worthwhile for every research group, databases, such as ... -
Prefix-Hijacking im Internetrouting: Monitoring, Analyse und Mitigation
Wübbeling, Matthias (2019-10-16)Die vorliegende Arbeit betrachtet IT-Sicherheitsaspekte des Internetroutings und verbessert etablierte Ansätze zur Entdeckung, zur Klassifikation und zur Untersuchung der Folgen von Anomalien im Internetrouting und entwickelt ... -
Preparation, properties and pharmacological testing of sulfonic acid nitrophenyl esters: Towards the development of sulfonic acid prodrugs of P1 and P2 receptor antagonists with potential peroral bioavailability
Luo, Yan (2003)Many pharmacologically active P1 and P2 receptor antagonists contain polar sulfonate groups, which are in many cases essential for their pharmacological activities and/or selectivities.<br /> Nitrophenyl sulfonate esters ... -
Preservation of Astrocytic Coupling Prevents Epileptogenesis
Müller, Julia (2018-10-23)Antiepileptic therapies are mainly based on drugs which target neuronal function. One third of epileptic patients do not respond adequately to these treatments and, importantly, all available drugs merely suppress seizures ... -
Preußische Kolonisations– und Sozialpolitik in der Altmark von 1740 bis 1850 im Spannungsfeld von Staatsräson und Bauernwiderstand: am Beispiel des Drömlings
Engelien, Ingeborg (2007)Das letzte Kolonisationsobjekt Friedrichs des Großen war die Urbarmachung und Besiedlung des Drömlings, eines Niederungsmoores in der Altmark am Ende des 18. Jahrhunderts. Dieses Thema ist Gegenstand der vorliegenden Arbeit ... -
Prevalence of resistance-nodulation-cell division-type efflux pumps and their contribution to antimicrobial resistance in Acinetobacter baumannii
Nowak, Jennifer (2017-03-29)Over the past three decades <em>A. baumannii</em> has evolved into a clinically important nosocomial pathogen causing epidemic outbreaks worldwide. Due to its intrinsic antimicrobial resistance and its ability to easily ... -
The primary cilium is a unique lipid microdomain engineered to transduce extracellular cues
Kaiser, Fabian (2022-04-06)Cilia are membrane protrusions located at the surface of almost every vertebrate cell. Cilia come in two different flavors: motile cilia, which generate a fluid flow or propel cells for active movement, and immotile, also ... -
Proanthocyanidins in barley and malt analyzed by pressurized liquid extraction, solid-phase extraction and HPLC
