Epistatic effects on carcass composition and meat quality in pigs
(2012-08-10)
The analysis of epistasis is not yet a routine, but it has been shown by few studies in livestock animals that interaction effects contribute with considerable proportions to the phenotypic variance. Therefore the objective ...
Wet Path Delay Corrections from Line-of-Sight Observations of Effelsberg’s Water Vapour Radiometer for Geodetic VLBI Sessions
(2012-08-01)
Water vapour induced excess path lengths in electromagnetic waves have been one of the most unmanageable errors in space geodesy, such as GPS and VLBI. The difficulty mainly comes from the highly variable distribution of ...
Effect of niacin on the efficiency of nitrogen utilisation in the rumen of dairy cows
(2012-08-14)
The aim of the present study was to investigate the effect of an oral niacin supplementation of 6 g per day to a diet deficient in ruminally degradable protein (RDP) on rumen metabolism, microbial protein synthesis, nitrogen ...
Design optimization of the ¯PANDA Micro-Vertex-Detector for high performance spectroscopy in the charm quark sector
(2011-09-01)
The ¯PANDA experiment is one of the key projects at the future FAIR facility, which is currently under construction at GSI Darmstadt. Measurements will be performed with antiprotons using a fixed-target setup. The main ...
The Formation of the Concertina Pattern: Experiments, Analysis, and Numerical Simulations
(2011-09-12)
The concertina is a magnetization pattern observed in elongated thin-film elements of a soft-magnetic material during the switching-process by an external magnetic field. The almost periodic pattern consists of stripe-like ...
Ferredoxin-dependent electron transport during methanogenesis from acetate
(2011-09-12)
Methanogenic archaea are one of the key groups in global carbon turnover. They metabolize the conversion of the end products of the anaerobic food chain to methane. Of particular importance is the methanogenesis with acetate ...
INTERSNP: Genomweite Interaktionsanalyse mit a-priori Information
(2011-09-12)
Das Ziel der Genetischen Epidemiologie ist DNA Sequenzvarianten im menschlichen Genom zu finden, die an der Entstehung von Krankheiten beteiligt sind. Genomweite Assoziationsstudien haben zur Identifikation von hunderten ...
Phasenbasierte Charakterisierung transienter gerichteter Interaktionen
(2011-09-15)
Eine Vielzahl von natürlichen, räumlich ausgedehnten, komplexen dynamischen Systemen kann als Kombination interagierender eigenständiger (Sub-)Systeme aufgefasst werden. Interaktionen zwischen diesen Systemen sind jedoch ...
Model electrodes for the electrooxidation of simple alcohols: a DEMS study
(2011-09-12)
Pt is considered as a model for fuel cell electrocatalysts. In the present thesis, I stud-ied the electrooxidation mechanisms of methanol (chapter 3) and ethanol (chapter 4) on different Pt surfaces, using a dual ...
