Place-renewing leadership:trajectories of change for mature manufacturing regions in Europe

The forces of globalisation now impacting on local economies pose threats to the existing paradigm of competences and routines, yet simultaneously offer opportunities to integrate new knowledge and learning. This is particularly pertinent with respect to Europe’s ‘mature regions’, which are undergoing a major economic restructuring by trying to shift from traditional manufacturing activities to hybrid activities that comprise a combination of manufacturing and a higher component of intangible inputs and related knowledge service activities. The objective of the article is to discuss the concept of ‘place leadership’ by looking at how the embedded skills, knowledge and cumulated learning of a place can be used by its institutional infrastructure to identify sustainable growth trajectories. In other words, its aim is to explore how the economic, social, institutional and cultural aspects of places shape the opportunities for upgrading and renovation drawing upon their historical specialisation. The conceptual contribution of the article draws on two case studies, in the West Midlands, UK and in Prato, Tuscany, where we study the processes of decision-making, forms of leadership and ultimately the nature of local leadership.

Viscosity of aged bio-oils from fast pyrolysis of beech wood and miscanthus:shear rate and temperature dependence

The viscosity of four aged bio-oil samples was measured experimentally at various shear rates and temperatures using a rotational viscometer. The experimental bio-oils were derived from fast pyrolysis of beech wood at 450, 500, and 550 °C and Miscanthus at 500 °C (in this work, they were named as BW1, BW2, BW3, and MXG) in a bubbling fluidized bed reactor. The viscosity of all bio-oils was kept constant at various shear rates at the same temperature, which indicated that they were Newtonian fluids. The viscosity of bio-oils was strongly dependent upon the temperature, and with the increase of the temperature from 30 to 80 °C, the viscosity of BW1, BW2, BW3, and MXG decreased by 90.7, 93.3, 92.6, and 90.2%, respectively. The Arrhenius viscosity model, which has been commonly used to represent the temperature dependence of the viscosity of many fluids, did not fit the viscosity-temperature experimental data of all bio-oils very well, especially in the low- and high-temperature regions. For comparison, the Williams-Landel-Ferry (WLF) model was also used. The results showed that the WLF model gave a very good description of the viscosity-temperature relationship of each bio-oil with very small residuals and the BW3 bio-oil had the strongest viscosity-temperature dependence.
