11. Interaction of Ultrashort X-ray Pulses with Material
Sammanfattning : Radiation damage limits the resolution in imaging experiments. Damage is caused by energy deposited into the sample during exposure. Ultrashort and extremely bright X-ray pulses from free-electron lasers (FELs) offer the possibility to outrun key damage processes, and temporarily improve radiation tolerance. LÄS MER
12. Pushing methods for plasma simulations into the QED regime
Sammanfattning : The interaction between a super-intense laser pulse, with intensity up to 10²² W/cm², and a plasma opens new regimes of physics, with new questions and more demand on existing numerical tools. Relativistic and quantum effects which are negligible for lower laser intensities become important and must be properly modelled to generate reliable predictions. LÄS MER
13. Towards International Chemical Safety : Taking Action on Persistent Organic Pollutants
Sammanfattning : Persistent organic pollutants (POPs) have been subject to increased international ro-operation over that past decade. The first international effort to address POPs collectively as a distinet class of pollutants was made under the United Nations Economic Commission for Europe (UNECE) and within the framework of the Convention on Long-Range Transboundary Air Pollution (CLRTAP), which geographically covers North America, Europe and the region of the former Soviet Union.

14. Implementation and Analysis of Air-Sea Exchange Processes in Atmosphere and Ocean Modelling
Sammanfattning : To understand and to predict the weather and climate, numerical models are important tools and it is crucial that the controlling processes are described correctly. Since 70% of the global surface is covered with water the description how the ocean and atmosphere communicates has a considerable impact. LÄS MER
15. A representative interactive linear-eddy-model (RILEM) for simulating spray combustion
Sammanfattning : Engine development aims at reducing pollutant emissions (e.g. NOx , soot,UHC) while maintaining high efficiencies. Detailed experimental resultsin combination with precise numerical predictions are of great importancein order to develop combustion systems for new clean and efficient inter-nal combustion engines.
