Boppard / Oberer Mittelrhein: Das Kneipp- und Mineralheilbad im Spannungsfeld unterschiedlicher Fremdenverkehrsarten
(1983)Boppard on the upper Middle Rhine. The health resort and spa in a field of tension torn between different types of tourism.
Tourism in Boppard had experienced a rapid upswing between 1951 and 1962. Although the ... -
Bose-Einstein condensation of erbium atoms for fractional quantum Hall physics
(2021-04-21)With the advent of ultracold atomic gases experimentally realized by laser cooling techniques nearly 40 years ago, the doors to accessing novel physical behaviour have been opened wide and far. Experimentally, research in ... -
Bose-Einstein Condensation of Rubidium: Towards Ultracold Binary Bosonic Mixtures
(2005)In this thesis, first experiments are reported towards the realization of ultracold Cesium-Rubidium mixtures. In particular, Bose-Einstein condensates (BECs) of Rubidium atoms have been created and combined samples of ... -
Bose-Einstein-Kondensation in einen photonischen Superpositionszustand
(2022-04-21)Die Bose-Einstein-Kondensation ist ein Phasenübergang zu einem Zustand bei dem bosonische Teilchen den Systemgrundzustand makroskopisch besetzen. Dieser besondere Aggregatzustand konnte zunächst mit ultrakalten atomaren ... -
Bose-Einstein-Kondensation von paraxialem Licht
(2011-03-02)Einer der faszinierenden Aspekte der Bose-Einstein-Kondensation ist, dass sie selbst in idealen, d.h. wechselwirkungsfreien, Bose-Gasen auftritt, wodurch sie sich grundlegend von allen Phasenübergängen unterscheidet, bei ... -
Bosnia and Herzegovina: a case study for the unfinished EU Agenda in the Western Balkans
(2018)Bosnien-Herzegowina hat ein Stabilisierungs- und Assoziierungs-Abkommen mit der Europäischen Union unterzeichnet und erhält zudem Heranführungshilfe von der EU, mit dem Ziel die Achtung von Rechtsstaatlichkeit und ... -
Bottom-up Object Segmentation for Visual Recognition
(2013-03-20)Automatic recognition and segmentation of objects in images is a central open problem in computer vision. Most previous approaches have pursued either sliding-window object detection or dense classification of overlapping ... -
Boundaries and Identities: The Case of Gilgit-Baltistan
(2016-06)The main argument of the paper is that the absence of Gilgit-Baltistan in the power dispensation and state structure of Pakistan has created a power vacuum in the society, which is gradually filled by sectarian forces, ... -
Boundary work and agricultural innovation systems: Stakeholder interaction and learning using an example of push-pull technology in Ethiopia
(2019-06-17)Maize is an important cereal crop for food security in Ethiopia. However, its productivity is low with average grain yields of less than 1 ton/ha which is below its potential of over 4 ton/ha. This is attributed to a variety ... -
Bounded Rationality, Heterogeneity and Learning
(2009-07-27)The dissertation deals with both a model in which agents with limited information conform to a learning rule, as well as boundedly rational consumers who follow simple rules of thumb. The first case is treated within a ... -
Bovine microRNomics: Implications during oocyte maturation and pathophysiology of endometrium
(2011-05-04)MicroRNAs which are known for posttranscriptional gene regulation are evidenced for their essential role during animal development and disease. In this study, identification and expression profiling of bovine miRNAs during ... -
Bovine ovarian hyperstimulation induced changes in expression profile of circulatory miRNA in follicular fluid and blood plasma
(2014-11-14)Circulatory noncoding small RNAs (miRNAs), which are present in various body fluids, are reported to be potentially used as biomarkers for disease and pregnancy. The present study was conducted to investigate the effect ... -
Bovine pre-transfer endometrium and embryo transcriptome fingerprints as predictors of pregnancy success after embryo transfer
(2010-10-08)Aberrant endometrial and embryonic gene expression is one of the causes of pregnancy failure in cattle. However, selecting cows with adequate endometrial receptivity and embryos of higher developmental competence based on ... -
Die Böden des oberen Ouémé-Einzugsgebietes in Benin/Westafrika: Pedologie, Klassifizierung, Nutzung und Degradierung
(2004)In dieser Arbeit werden die im oberen Ouémé-Einzugsgebiet Zentralbenins gelegenen Böden charakterisiert und die Degradierung in dem aktuellen low input-Landnutzungssystem untersucht. Darauf aufbauend werden Möglichkeiten ... -
BPS state counting using wall-crossing, holomorphic anomalies and modularity
(2013-07-25)In this thesis we examine the counting of BPS states using wall-crossing, holomorphic anomalies and modularity. We count BPS states that arise in two setups: multiple M5-branes wrapping P x T2, where P denotes ... -
Brachflächenrevitalisierung im Rahmen der Flächenkreislaufwirtschaft
(2009)In Deutschland wird eine nachhaltige Siedlungspolitik verfolgt, die einen sparsamen Umgang mit Grund und Boden in sozialverträglicher und ökologischer Flächennutzung vorsieht. Daher hat die Bundesregierung sich zur ... -
Braiding Knots with Topological Strings
(2015-08-28)For an arbitrary knot in a three-sphere, the Ooguri-Vafa conjecture associates to it a unique stack of branes in type A topological string on the resolved conifold, and relates the colored HOMFLY invariants of the knot to ... -
Branchenbezogene Risikobeobachtung im Arbeitsschutz: Möglichkeiten und Grenzen
(2019-06-03)Die Veränderungen in der Arbeitswelt schreiten unaufhaltsam voran. Durch den Einzug immer neuerer Technologen in den Arbeitsalltag, die Entgrenzung von Arbeit und Beruf sowie die alternde Bevölkerung ergeben sich stetig ... -
Brechungsindexänderungen in Lithiumniobat-Kristallen durch Strahlenschäden
(2007)Die Bestrahlung der LiNbO3-Kristalle mit 3He2+ -Teilchen und einer Energie von ca. 40 MeV erzeugt ein atomares Schäden im Kristall und dies führt zu einer starken ortaufgelösten Brechungsindexänderung ... -
Breeding progress for drought tolerance and nitrogen use efficiency in winter wheat (Triticum aestivum L.)
(2022-03-28)Drought is the major abiotic stress factor limiting agricultural production in arid, semi-arid as well as in temperate regions around the world, whereas nitrogen (N) is one of the most important nutrients for crop production. ...
