Monitoring der Vegetationsdynamik in Ostafrika mit multisensoralen Satellitendaten
(2009-01-08)
Diese Arbeit hat zum Ziel, die Vegetationsbedeckung sowie die Vegetationsdynamik in ihrer saisonalen und interannuellen Ausprägung mit Hilfe multisensoraler Satellitendaten zu erfassen. Auf unterschiedlichen zeitlichen und ...
Theoretical Aspects of Cosmic Shear and its Ability to constrain Cosmological Parameters
(2009-03-13)
In the last decade weak gravitational lensing by the large-scale structure of the Universe, also called cosmic shear, has become an important tool to constrain cosmological parameters. Despite this success there remain ...
Environment and Properties of Submillimeter Galaxies
(2009-03-06)
Extra-galactic surveys with large submillimeter bolometer cameras discovered a population of dust obscured starbursting galaxies at high redshifts. These submillimeter galaxies (SMGs) are crucial in the stellar build up ...
Regionalisation of human ES cell derived neural precursors
(2009-03-13)
The derivation of region-specific neural cells from human embryonic stem cells holds great promise for future cell replacement strategies of neurodegenerative diseases. However, the possibility to recreate the diversity ...
Darstellung von Terpenacyl-β-D-glucopyranosiden: Spaltung von Benzylschutzgruppen mittels katalytischer Transferhydrogenolyse in Gegenwart multifunktioneller Aglyca
(2009-03-23)
Ausgangspunkt der vorliegenden Arbeit war der erfolgreiche Einsatz der katalytischen Transferhydrogenolyse bei der Synthese des antiviral wirksamen 1',6'-O-Diacylglucosids "Cunilosid". Analog dieser Synthese sollte ...
Blue-Light Sensing in Arabidopsis: In Vivo Microscopy of Subcellular Localization, Endocytosis, and Vesicular Recycling of the Blue-Light Receptor Phototropin 1
(2009-03-13)
In this thesis, the subcellular localization and possible functions of the blue light receptor, PHOT1, is examined. Results are presented, which indicate that blue lightinduced relocalization of auxin efflux carriers ...
On Rho Invariants of Fiber Bundles
(2009-07-21)
Using adiabatic limits of Eta invariants, Rho invariants of the total space of a fiber bundle are investigated. One concern is to formulate the aspects of local index theory for families of Dirac operator in terms of the ...
The Influence of Land-use Activities on Nutrient Inputs into Upland Catchment Streams, Ghana
(2009-10-08)
In Ghana, increasing agricultural productivity is seen as an essential component of most development programs. The main objective of this study was to assess the implications of increased land-use activities on in-stream ...
Studying Galaxy-Galaxy Lensing and Higher-Order Galaxy-Mass Correlations Using the Halo Model
(2009-06-22)
In recent years, the distribution of galaxies in the Universe could be measured up to large distances and over a significant part of the sky. The analysis of this large-scale structure contains a wealth of cosmological ...
Identifikation und Charakterisierung von Interaktionspartnern des Proteins Polyduktin
(2009-04-21)
Die Autosomal-recessive polyzystische Nierenerkrankung ist eine der bedeutensten Nephropathien im Kindesalter. Die meisten Patienten präsentieren bereits in utero bilateral vergrößerte zystische Nieren und eine ...
