Quaternary Stratigraphy and Climate in the Near East
Butzer, Karl Wilhelm (1958)Altough the study is primarily palaeoclimatological in scope, it has been possible to obtain an invaluable insight into the Quatemary morphology of the Near East during a private field-trip to Egjrpt and Jordan in the ... -
The Quest for the η and η' Transition Form Factors: A Stroll on the Precision Frontier
Holz, Simon (2022-10-04)An important precision test of the Standard Model of Particle Physics is posed by the prediction of the anomalous magentic moment of the muon. Currently, a deviation of about 4.2σ persists between the experimental ... -
The Quintuplet cluster: A young massive cluster study based on proper motion membership
Hußmann, Benjamin (2014-01-27)Young massive clusters define the high mass range of current clustered star formation and are frequently found in starburst and interacting galaxies. As - with the exception of the nearest galaxies within the local group ... -
Quiver Modulations and Potentials
Geuenich, Jan (2017-04-11)We introduce DWZ (Derksen-Weyman-Zelevinsky) mutation for a special class of SPs (species with potential). Generalizing a construction of Labardini-Fragoso, we associate with each triangulated, constantly weighted orbifold ... -
Radarinterferometrische Untersuchungen mit ERS-1/2 auf der Antarktischen Halbinsel
Moll, Albert (2008)Synthetic Aperture Radar Interferometry (InSAR) ermöglicht effiziente Untersuchungen von polaren Regionen, mit denen ein Beitrag zur Bestimmung von Massenbilanzen geleistet werden kann. Dieser Parameter hat entscheidenden ... -
Radialgliaähnliche Vorläuferzellen aus pluripotenten Stammzellen: ein stabiles Intermediat zur effizienten Generierung humaner Oligodendrozyten
Gorris, Raphaela (2017-09-12)Als myelinproduzierende Zellen spielen die Oligodendrozyten eine essenzielle Rolle für die Funktionalität des Zentralnervensystems (ZNS). Sie bilden die isolierenden Myelinscheiden der Neurone und garantieren so eine ... -
Radiation damage of polymers in ultrasonic fields
Anbalagan, Poornnima (2008)Radiation damage has always been a topic of great interest in various fields of sciences. In this work, an attempt is made to probe into the effect of sub-threshold ultrasonic waves on the radiation damage created by ...

Radikalkationensalze und Charge-transfer-Verbindungen elektronenreicher Chalkogenanthrene und TTF-Derivate
Schipmann, Karen-Christina (2019-05-08)Im Rahmen der Arbeit ist es gelungen, zahlreiche neue Radikalkationensalze und Charge-Transfer-Addukte mit unterschiedlichen Strukturmotiven zu erhalten und zu charakterisieren. Als Donoren und Radikalkationenbildner wurden ... -
The Radio Continuum Halos of the Edge-on Galaxies NGC 891 and NGC 4565
Schmidt, Philip (2016-10-13)The halos of spiral galaxies are complex entities consisting of multiple matter components, generally including neutral and ionized gas phases, cosmic rays (CRs), dust, as well as extraplanar stars. The detection of ... -
Radio Continuum of Galaxies with H2O-Megamaser-Disks
Kamali, Fateme (2019-11-08)Galaxies with H2O-megamaser-disks are low luminosity active galaxies where 22GHz H2O-maser emission is detected in their accretion disk surrounding the central supermassive black hole (SMBH). Furthermore, ... -
Radio Emission from Cosmic Ray Air Showers
Huege, Tim (2005)Charged particles with energies ranging from a few times 106 eV up to ≥ 1020 eV continuously impinge on the earth as so-called “cosmic rays”. Their study constitutes an important field of research in ... -
Radio emission from massive Young Stellar Objects and their surroundings: Characterization and feedback
Serrano Medina, Sac Nicte Xiomara (2020-10-12)Massive stars or high-mass stars dominate their galactic environments. They play a major role in the energy budget of galaxies and are essential in their evolution. However, high mass star formation is not fully understood, ... -
A radio view on the structural evolution of massive star-forming galaxies across cosmic time
Jiménez-Andrade, Eric Faustino (2020-03-06)It is not well understood what processes regulate the global formation of stars in galaxies throughout cosmic history. My work aims to measure the structural evolution of star-forming galaxies (SFGs), from the present back ... -
Radiometalle in der nuklearmedizinischen Anwendung: Prozessentwicklung und Translation in die klinische Routineanwendung
Meisenheimer, Michael (2022-04-20)In der vorliegenden Arbeit wurden mehrere Aspekte der täglichen radiopharmazeuti-schen Arbeit in der Nuklearmedizin bearbeitet. Der Fokus lag dabei auf der Translation von neuen Tracern aus der Forschung in die klinische ... -
Rainforest change analysis in Eastern Africa: A new multisourced, semi-quantitative approach to investigating more than 100 years of forest cover disturbance
Mitchell, Nicholas (2012-01-11)Forest change and disturbance of the past strongly influence the state of today’s forests and their biodiversity. However, knowledge of former forest landscape states can be subject to misunderstanding and the practical ... -
