Genotoxicity of flavouring substances (Project)
Sometimes there are no or only a few genotoxicity data available for food components. Especially in cases in which there is no basis to request data by law, the project is intended for contributing genotoxicity data. In vitro tests are used according to OECD guidelines.

Development of sample clean-up procedures preparing GC-C-IRMS measuremens of residues and contaminants in food (Project)
The measurement of stabile isotope ratios of carbon and oxygen by means of GC-C-IRMS (Gas Chromatographie-Combustion-Isotope Ratio Mass Spectrometry) demands a thoroughly developed sample clean-up leading to a baseline separation of the analytes of interest from matrix compounds during gaschromatography. Due to the low concentrations of residues and contaminants in food this is a not only a...

SPP 1090 AG 4: 14C as a source of information for the mechanisms of carbon fixation in soils (Project)
Accelerator mass spectrometry (AMS) will be applied for the reconstruction of the pathways of radioactive carbon, 14C, produced in atmospheric nuclear tests, through the biosphere and organic soil components to the refractory soil carbon fraction. The very low sample masses (0.1 to 1 mg carbon) required for AMS measurements are well suited for a detailed subdivision of soil material into...

SPP 1090 AG 4: Distribution and stability of carbon during the degradation of 14C-labelled wheat straw in the different compartments of a soil with a different agricultural fertilization practice (Project)
It has been hypothesised that beside non degraded plant debris the soil organic matter roughly consists of two compartments. Governed by the content of clay and fine silt fractions an inert C-pool develops during the formation of soils. This carbon bound to the fine mineral particles participates in C-turnover in soils only over long term ranges. In dependence on agricultural practice a second,...

SPP 1090 AG 4: Quantification and modeling of carbon turnover of arable soils as related to soil texture (Project)
Most models for the turnover of soil organic matter (SOM) include a number conceptual SOM pools. These pools represent fractions with a different degree of stabilization. One main process of SOM stabilization is the physical protection of both decomposable and recalcitrant substances. Therefore a new model concept is to develop for the whole carbon turnover of arable soils exceeding the hitherto...

Evaluation of the EU policy for rural areas: comparative analysis for evaluation practices taking the investment in agricultural holdings in Germany and the United Kingdom as an example (Project)
Achievement of systematic knowledge on evaluation performance and the use of evaluation; contribution to the improvement of the present evaluation practice and therefore increase of the efficiency and effectivity of the common policy for rural development in the EU

Transforming Rural Communication (Project)
The general objective of the project is to consolidate a transdisciplinary and trans-sectoral approach to the problem of communication in rural areas, to raise awareness among practitioners and academics of the specificities of rural communication and of the principles of „progressive rural communication“ and to build a core network of academics and practitioners around this topic. The general...
