UAV Applications for Intensive Forest Monitoring
(2024-02-26)Intensive forest monitoring at Level II plots in Europe necessitates standardization for observing and measuring forest parameters, allowing for comprehensive assessments across various scales. The harmonization of these ... -
Ultra-high field NMR spectroscopy of GABA in the human brain
(2023-08-31)Magnetic resonance imaging (MRI) is a non-invasive and radiation-free imaging method that has been utilized in medicine for decades. Using magnetic fields, the nuclear spins within the tissue are perturbed, and the resulting ... -
Ultradünne Glasfasern als Werkzeug zur Kopplung von Licht und Materie
(2007)Gegenstand der vorliegenden Arbeit sind ultradünne Glasfasern, die als neuartiges Werkzeug für die Kopplung von Licht und Materie eingesetzt werden. Die zugrunde liegende Idee hierbei ist, die Materie (Atome, Moleküle, ... -
Ultrakalte Erbiumatome in einer CO2-Laser Dipolfalle
(2016-09-06)Mit Hilfe ultrakalter Gase sind in der Physik zahlreiche neue Forschungsgebiete erschlossen worden, es gelang beispielsweise die Realisierung atomarer Bose-Einstein Kondensate und atomarer quantenentarteter Fermigase oder ... -
Ultraschnelle zweidimensionale Infrarotspektroskopie und ab initio Berechnungen an OH- und NH-Streckschwingungen
(2013-12-16)Untersuchungen an Modellsystemen von Wirt-Gast-Komplexen bilden die Grundlage für pharmazeutisch-technische Forschung und Entwicklung auf dem Gebiet der Medikamentensynthese. In dieser Arbeit wurde mit Hilfe von ultraschneller ... -
Ultrastructure, Formation and Evolution of Chaetae in Annelids
(2016-02-02)Annelid systematics has been quite unstable over the past century. Especially, with the introduction of molecular techniques to unravel phylogenetic relationships, previously established morphology-based phylogenetic trees ... -
Ultrastruktur der Kopfnieren (head kidneys) von sedentären Polychaeten und ihre Bedeutung für die Phylogenie der Annelida
(2013-04-10)Die Phylogenie der sedentären Polychaeten ist bisher ungeklärt. Die Polychaetentaxa Terebelliformia, Arenicolidae und Capitellidae sowie die Echiura zeigen jedoch in vielen Phylognieanalysen eine nahe Verwandschaft. Innerhalb ... -
Ultrastrukturelle Analyse sowie Steuerung der Substratadhäsion kardialer Zellen
(2012-06-04)Fokaladhäsionen symbolisieren nicht nur einfache starre Verankerungspunkte der Zelle an das extrazelluläre Substrat, sondern sie stellen hochdynamische Multiproteinaggregate innerhalb der Zelle dar, die je nach Anforderung ... -
Unbounded Bivariant K-theory and an Approach to Noncommutative Fréchet Spaces
(2011-09-19)In the current work we thread the problems of smoothness in non-commutative $C^*$-algebras arising form the Baaj-Julg picture of the $KK$-theory. We introduce the notion of smoothness based on the pre-$C^*$-subalgebras of ... -
Uncertainty in mesoscale numerical weather prediction: probabilistic forecasting of precipitation
(2015-11-19)Over the last decade, advances in numerical weather prediction (NWP) led to forecasts on even finer horizontal scales and a better representation of mesoscale processes. High-resolution mod- els provide the user with ... -
Uncertainty Reduction in Diffusion Magnetic Resonance Imaging Tractography
(2024-04-04)Diffusion Magnetic Resonance Imaging (dMRI) is currently the only non-invasive method capable of mapping the geometry and microstructure of major white matter tracts in vivo. This technique measures the movement of water ... -
The Uncinate Processes in Birds and their Implications for the Breathing Mechanics of Maniraptoran Dinosaurs
(2004)The breathing mechanics of dinosaurs and the connected implications for lung structure (Perry 1983) and metabolism is currently a focus of intense and sometimes controversial discussion (Perry in press). Rubens et al (1997) ... -
Understanding social ecological change through palm use and management
(2015-03-31)As people change their livelihood preferences, they change the way they relate to the natural resources around them. Anticipating and managing these changes, where possible, is a major challenge for sustainable land-use ... -
Understanding the impact of massive star formation on its surroundings in Messier 8
(2020-06-04)Massive stars inject an immense amount of energy into their surroundings, which affect the physics and chemistry of the interstellar medium (ISM). Massive stars play a significant role in the evolution of galaxies. The ... -
Understanding the role of SATB1 in CD4+ T cells by analysis of conditionally targeted mice generated by genetic engineering
(2018-12-12)Special-AT-rich-binding protein 1 (SATB1) is a nuclear protein providing higher order chromatin organization and regulation of gene expression, especially in T cells. In regulatory T cells, SATB1 is repressed to maintain ... -
Understanding the systemic immune response in COVID-19 – one cell at a time

Underwater flight in sea turtles and plesiosaurs: Dissection, muscle reconstructions, analog models, and finite element structure analyses inform on flipper twisting and muscle forces in plesiosaurs
(2020-08-13)This dissertation contributes to our understanding of plesiosaur locomotion by providing foreflipper and hindflipper muscle reconstructions and studying aspects of their muscle physiology (functions, forces, muscle length ... -
Unexpected chromosomal DNA transfer from Agrobacterium tumefaciens to plant cells: mechanisms and solutions
(2015-01-09)The soil bacterium and plant pathogen <i>Agrobacterium tumefaciens</i> has the ability to transfer a defined part of its genome, the so called transferred DNA (T-DNA), to plant cells. This transfer has been successfully ... -
Ungewöhnliche titanocenvermittelte Reaktionen
(2006)Die Arbeit behandelt radikalische Zyklisierungen die durch Titanocen(III)chlorid katalysiert werden. Epoxide werden unter der von Gansäuer et al. entwickelten Titanocenvermittelten reduktiven Epoxidöffnung homolytisch ... -
A Unified Formation Scenario for the Zoo of Extended Star Clusters and Ultra-Compact Dwarf Galaxies
(2014-07-18)In the last decade, very extended old stellar clusters, which cover a large mass range, have been found in various types of galaxies in different environments. Objects with masses comparable to normal globular clusters ...
