Uranyl, a strong Lewis acid, forms stable complexes with relatively hard donors and it is commonly believed that uranyl complex with trialkylamine is stabler than trialkylphosphine. However, there are no thermodynamic parameters to evaluate the complexation stabilities of R 3 N-UO 2 2+ and R 3...

Uranium extraction from seawater has attracted increasing attentions for nuclear raw material to support the sustainable development of nuclear power plants. However, it is still a grand challenge to overcome the high salinity background and ultra-low uranyl concentration. Herein, we...

This paper evaluates the appropriateness of the standard methodologies and the quality of the data frequently used to analyse labour market dynamics in Europe. Our results indicate that, due to recall error and heterogeneous survey design, the retrospective approach tends to result in a...

In dem Heft werden drei Papiere vorgestellt, die im Oktober 2000 auf einem Workshop in Heidelberg vorgetragen wurden. Gefragt wird danach, inwieweit die sog. 'new economy' mit neuen Formen der Arbeitsorganisation verbunden ist. Ziel des Workshops war es, eine theoriegestützte komparative...
