Speaker Prof. Mattias Hallquist Professor Department of Chemistry and Molecular Biology University of Gothenburg Sweden Abstract The secondary organic aerosol (SOA) represents a dominant fraction of the tropospheric aerosol. Still, the current level of understanding of SOA processes is remarkably low compared to other processes in aerosol science, i.e. modelled SOA based on experimental findings and existing theory do not capture the variability of observed SOA loadings. Lately, models have been improved by adding sources/processes to reduce the bias but still there is no model that is capable of describing SOA satisfactorily while capturing a large temporal and spatial variability. The uncertainties associated with SOA relates to its formation from atmospheric oxidation of volatile organic compounds (VOCs). The complexity is ...

Speaker Mr. Steve Whitfield Manager of Customer Technical Services Tata Steel Group Abstract Hot Finished Structural Hollow Sections in building construction has become more and more popular owing to the architecturally aesthetic appearance and the structural efficiency under compression loading. For critical applications the correct use of Hot Finished Structural Hollow Sections can lead to safer use plus reduce member sizes significantly, rendering attractive visual and spacious impacts on the building layout. Hot Finished Structural Hollow sections are used for all forms of fabrication from the basic requirement through to the critical applications such as building's and offshore. It is important to know the different types of hollow sections including the specification and traceability. The half-day seminar will cover topics ...
