Studies into the mis-identification probability of tau leptons and a measurement of the cross section σ(pp → W) × BR(W → τντ) at a center-of-mass energy of √s = 7 TeV with the ATLAS detector
(2016-02-23)
Since the start of data taking in the year 2009 the Large Hadron Collider has been operated very successfully. Next to the ongoing efforts to fully determine the properties of the newly found Higgs-like boson, precision ......
Physiological and Molecular Characterization of Kenyan Barley Lines (Hordeum vulgare L.) for Abiotic Stress Tolerance and Malting Attributes
(2016-01-11)
Abiotic stresses such as drought, salinity agriculturally poor soils, and inappropriate fertilizer usage as factors of production determining yield and quality of barley for various end uses challenges the production of ...
Arabidopsis thaliana aldehyde dehydrogenases ALDH3H1 and ALDH3I1: cysteine mutations, S-nitrosylation and esterase activity
(2016-04-20)
S-nitrosylation is a posttranslational modification that is known to affect many biochemical processes in plants. In the current study the ability of NO donors to S-nitrosylate aldehyde dehydrogenases ALDH3H1 and ALDH3I1 ......
Field observations and numerical simulations on the role of local structures and seismic source characteristics in the in uence of external earthquakes in volcanic and hydrothermal activity
(2016-02-10)
Earthquakes can trigger volcanic and hydrothermal activity at a large distance range and a wide time window. While advances in observations in the last two decades have helped to establish that there exist a causal connection ...
Characterization of the Role of Insulin, IGF-1 and their Receptor Signaling in Proliferation and Survival of Non-Small Cell Lung Cancer Cells
(2016-02-24)
1 Background
Since recent years it has been assumed that the anabolic hormone insulin might contribute to tumor cell proliferation as the cognate hormone IGF-1. This hypothesis was supported by ...

Funktionelle Charakterisierung der Chaperon-assoziierten Ubiquitinligase CHIP in Drosophila melanogaster
(2016)
In der vorliegenden Arbeit konnte die Chaperon-assoziierte Ubiquitinligase CHIP als zentrales Bindeglied zwischen Proteinhomöostase („Proteostase“) und Alterung identifiziert werden. Neben seiner Rolle als Proteinqualitä ......
Synthesis of ligands for self-assembly of discrete metallo-supramolecular complexes
(2016-02-22)
Different aspects of self-assembly and self-sorting of metallo-supramolecular have been investigated in this thesis. Starting with self-sorting, four different 9,9'-spirobifluorene derivatives substituted with pyridine ...
Coherence effects and spectroscopy in laser driven dense atomic vapour
(2016-02-24)
In this work quantum coherence effects in dense rubidium atomic vapour are investigated. Prepared in a laser driven atomic system, coherent effects, like the well-known electromagnetically induced transparency, have a ...
Intramembrane proteolysis of ephrin-B2 by γ-secretase regulates podosome dynamics and migration of microglia
(2016-01-20)
The Eph-ephrin system plays pivotal roles during development and adulthood in cell-cell interaction, cell adhesion and migration. It has previously been shown that ephrin-B1 and 2 can be cleaved intramembranously by the ...
Herstellung und Charakterisierung ultraweicher Elastomere für die Lebend-Zellanalyse
(2016-01-21)
Biomimetische Materialien werden in zellmechanischen Analysen verwendet, um die natürliche Umgebung einer Zelle so getreu wie möglich nachahmen zu können. Die mechanischen Eigenschaften wie die Viskoelastizität dieser ...
