The British Geological Survey has operated a World Data Centre for Geomagnetism since 1966. Geomagnetic time-series data from around 280 observatories worldwide at a number of time resolutions are held along with various magnetic survey, model, and activity index data. The operation of this data centre provides a valuable resource for the geomagnetic research community. The operation of the WDC...

Since the origin of the Modern Movement, there has been a basic commitment to improving housing conditions and the well-being of occupants, especially given the prediction that 2/3 of humanity will reside in cities by 2050. Moreover, a compact model of the city with tall buildings and urban densification at this scale will be generated. Continuous constructive and technological advances have de...

The metal sulfi des exhibit a great diversity of electrical and magnetic properties with both scientifi c interest and practical applications. These properties apply major constraints on models of the electronic structure (or chemical bonding) in sulfi des (Vaughan and Rosso 2006, this volume). The pure and doped synthetic equivalents of certain sulfi de minerals have actual or potential applic...
