Active Plasmonic and Dielectric Nanoantennas
(2017-08-10)This thesis presents results on the fabrication, investigation and characterization of active optical nanoantennas. The three partial results in order of their occurrence are: (i) The demonstration of the operational ... -
Activity coefficients of binary methanol alcohol mixtures from cluster weighting
(2020-07-23)The hydrogen bond network of different small alcohols is investigated via cluster analysis. Methanol/alcohol mixtures are studied with increasing chain length and branching of the molecule. Those changes can play an important ... -
Activity patterns in the septal-hippocampal network predict voluntary locomotion
(2018-07-13)In the brain of animals, locomotion is encoded and represented in multiple ways. During locomotion, the hippocampus (HC) displays characteristic activity patterns that change from asynchronous states when the animal is ... -
Activity-Dependent Regulation of Neuronal Ion Channel Expression During Epileptogenesis
(2005)Status epilepticus (SE) is known to cause numerous structural and functional alterations in brain. In this study, expression of various voltage-gated ion channels in rat hippocampal CA1 neurons were investigated at different ... -
The Acyl-ACP Thioesterase FatM from Lotus japonicus is involved in lipid transfer during Arbuscular Mycorrhiza Symbiosis
(2020-01-27)Arbuscular mycorrhiza colonization of roots is an ancient symbiosis that presumably was involved in the conquest of the land by early plants. Its main benefit for plants is the increased access to soil mineral nutrients ... -
Adaptation primärer Afferenzen und Hirnstammneuronen im Seitenliniensystem des Goldfisches, Carassius auratus, auf sequenzielle Reize
(2016-07-29)Weltweit sind ca. 33.000 Fischarten beschrieben, die sich in ihren Lebensraumansprüchen und in ihrer Lebensweise oft deutlich voneinander unterscheiden. Alle bisher beschriebenen Fische und aquatisch lebende Amphibien ... -
Adaptations of the four-striped field mouse (Rhabdomys pumilio, Sparman 1784) to the Namib Desert
(2003)Animals living in arid conditions need to adapt to a number of environmental factors, namely intense solar radiation, extreme temperatures, low humidity, (dry) winds, and temporal and spatial unpredictability of both water ... -
Adapting OpenCourseWare Based on the Needs and Preferences of Disabled Learners
(2022-12-22)OpenCourseWare (OCW) systems are becoming a significant source of learning that are widely used for various educational purposes. With the COVID-19 Pandemic situation, these resources showed the impact of having material ... -
Adaptive Methods for Robust Document Image Understanding
(2013-04-09)A vast amount of digital document material is continuously being produced as part of major digitization efforts around the world. In this context, generic and efficient automatic solutions for document image understanding ... -
Adaptive numerical simulation of contact problems: Resolving local effects at the contact boundary in space and time
(2012-10-24)This thesis is concerned with the space discretization of static and the space and time discretization of dynamic contact problems. In particular, we derive a new efficient and reliable residual-type a posteriori error ... -
Adaptive Scattered Data Fitting with Tensor Product Spline-Wavelets
(2005)The core of the work we present here is an algorithm that constructs a least squares approximation to a given set of unorganized points. The approximation is expressed as a linear combination of particular B-spline wavelets. ... -
Adding New Functionalities to Optical Fiber Cavities by Direct Laser Writing
(2023-12-12)Fiber Fabry–Pérot cavities (FFPCs) are fiber-based optical cavities, which find widespread applications, for example, in cavity quantum electrodynamics, spectroscopy, sensing, metrology, and in many more fields. They provide ... -
Addis Ababa Airport zwischen Globalisierung und Fragmentierung: Ein Hub in Raum und Zeit
(2019-03-15)Diese Forschungsarbeit untersucht den Flughafen von Äthiopiens Kapitale Addis Abeba als einen Ort, an dem verschiedenartige, teils ambivalente Entwicklungen zusammen¬treffen. Der Bole International Airport steht als Beispiel ... -
Adenosin-Rezeptoren und neurodegenerative Erkrankungen: Untersuchung des Einflusses von Cholesterol und Evaluierung neuer funktionalisierter Liganden als pharmakologische Werkzeuge
(2008)Adenosin-Rezeptoren gehören zur Familie der G-Protein-gekoppelten Rezeptoren und werden anhand ihrer pharmakologischen Eigenschaften in vier Subtypen, A1-, A2A-, A2B- und A3-Rezeptoren, unterteilt. Sie sind im Körper weit ... -
Adenosinrezeptoren auf humanen T-Lymphozyten: Modulation durch Subtyp-selektive Rezeptor- Agonisten und -Antagonisten
(2009-03-25)Die G-Protein-gekoppelten Adenosinrezeptoren sind im Körper weit verbreitet und an einer Vielzahl physiologischer Funktionen beteiligt; unter anderem wird ihnen eine wichtige Rolle im Immunsystem zugeschrieben. Eine ... -
Adherence Management for Cancer Patients on Capecitabine
(2014-01-13)The oral anticancer drug capecitabine is given twice daily for 14 days followed by a seven day rest period. Adequate patient adherence is essential for treatment success.
The present study aimed at developing and ... -
Adsorption and Selective Hydrogenation of α, β-unsaturated Aldehydes on Pt(111) and Pt-Sn Model Catalysts
(2007)Studies of complex interacting systems such as the adsorption of α , β-unsaturated aldehydes on model catalyst surfaces are a present day challenge. Although numerous studies have been published on the catalytical properties ... -
The Adsorption Geometry of PTCDA on Ag(111): an NIXSW Study
(2008)The bonding lengths of a large pi-conjugated molecule which was adsorbed on a metal surface were determined for the first molecular layer. The system consisting of the organic molecules 3,4,9,10-Perylenetetracarboxylic ... -
Adsorption von kleinen und großen Molekülen auf katalytisch aktiven Metalleinkristallelektroden
(2017-12-20)Die Adsorptionsprozesse sind für die Oberflächenreaktionen und insbesondere für die heterogene Katalyse entscheidende Reaktionsschritte. In dieser Arbeit werden die Adsorptionskinetiken und -modelle von adsorbiertem ...
