Interrelationships between mutualistic endophytic microorganisms, the root-knot nematode Meloidogyne incognita and the sap-sucking insect Aphis gossypii on tomato, squash and Arabidopsis
(2012-02-02)
The effects of single and combined applications of three endophytic microorganisms on the biocontrol of the root-knot nematode Meloidogyne incognita and the sap-sucking insect Aphis gossypii in tomato, squash and Arabidopsis ......

Multiscale Analysis of Adaptive Population Dynamics
(2012-01-11)
In this thesis we study a spatial population model based on a class of interacting locally regulated branching processes. The results consist of three parts which are independent of each other. The first part, which is the ...
Heterogeneity of soil properties at the field-scale and spatial patterns of soil-borne pests and weeds
(2012-04-16)
Soil heterogeneity at the field-scale not only affects crop growth and yield, but also spatial patterns of soil-borne pests and weeds. Therefore, site-specific management in due consideration of soil variability is required ...
Optimising nitrogen use in dairy farming: Evaluation of ruminal crude protein degradation and protein value of forages
(2012-01-16)
A major goal of modern dairy farming is to decrease nitrogen inputs and increase efficiency of nitrogen utilisation by the dairy cow in order to minimise environmental pollution and save on expensive nitrogen supplements. ...
Gas Electron Multipliers: Development of large area GEMS and spherical GEMS
(2012-01-06)
Gaseous radiation detectors have been a crucial part of high-energy physics instrumentation since the 1960s, when the first multiwire proportional counters were built. In the 1990s the first micropattern gas detectors ...
Functional Analysis of the Xin-Repeat Protein Family in Cross-striated Muscle
(2011-11-29)
The assembly of the sarcomere of cross-striated muscle involves a plethora of transcription factors, signalling and structural proteins and requires their coordinate interplay in order to construct this uniquely regular ...
Rainforest change analysis in Eastern Africa: A new multisourced, semi-quantitative approach to investigating more than 100 years of forest cover disturbance
(2012-01-11)
Forest change and disturbance of the past strongly influence the state of today’s forests and their biodiversity. However, knowledge of former forest landscape states can be subject to misunderstanding and the practical ...
Studien zur Aufklärung der Biosynthese apoplastischer Polyester in höheren Pflanzen
(2011-11-15)
Suberinablagerungen in den Wurzeln höherer Pflanzen tragen entscheidend zur Regulation des Wasserhaushaltes bei. Sie ermöglichen der Wurzel eine selektive Aufnahme von Nährstoffen, erlauben den Ausschluss toxischer Substanzen ...
Long bone histology of basalmost and derived Sauropodomorpha: the convergence of fibrolamellar bone and the evolution of giantism and nanism
(2012-01-11)
This study reports on long bone histology and growth in sauropodomorph dinosaurs. Derived members of Sauropodomorpha, the sauropods, were the largest terrestrial animals our planet has ever seen. New methods have recently ...
N-Heterocyclic Carbene Palladium Pincer Complexes: Synthesis, Aggregations and Catalytic Applications
(2011-11-29)
The work presented herein describes an investigation of a new class of pyridine-bridged bis- (benz)imidazolium salts and N-heterocyclic pincer carbene complexes derived there from, as well as their implication as homogenious ......
