EU Environmental Policy under Pressure: Chemicals Policy Change between Antagonistic Goals?

Until now, chemicals policy was unable to find a method to establish a sound balance between the benefits and risks of chemical substances. Policy learning within the European Union (EU) resulted in the formulation of an alternative approach to future chemicals policy in some quarters. The Commission's proposal for new chemicals legislation - presented as 'paradigmatic' policy change - led to a highly controversial lobbying debate. This paper deals in particular with the influence of structures, policy networks, multi-level governance and the influence of new modes of governance on chemicals policy-making. It argues that future policy will not represent the paradigmatic change announced by the Commission but only one incremental, cost-effective step towards such a reform. The final proposal is criticised as a neo-liberal interpretation of the Lisbon strategy which includes a dangerous shift in environmental policy making.

The role of deposition process on pressure dip formation underneath a granular pile

This paper describes an experimental investigation on the pressure dip phenomenon in a conical pile of granular solids. The roles of different deposition processes such as the pouring rate, pouring height and deposition jet size on the pressure dip formation were studied. Test results confirmed that the pressure dip is a robust phenomenon in a pile formed by top deposition. When the deposition jet radius is significantly smaller than the final pile radius (i.e. concentrated deposition), a dip developed in the centre as shown in previous studies. However, when the deposition jet radius is comparable to the final pile radius (i.e. diffuse deposition), the location of the dip moves towards the edge of deposition jet, with a local maximum pressure developed in the centre. For concentrated deposition, an increase in the pouring rate may enhance the depth of the dip and reduce its width, while an increase in the pouring height has only a negligible effect in the studied range. The results suggest the pressure dip is closely related to the initial location, intensity and form of downslope flows. © 2013 Elsevier Inc. All rights reserved.
