Neither Shoreditch nor Manhattan: Post-politics, 'soft austerity urbanism' and real abstraction in Glasgow North

Speirs Locks is being re-constructed as a new cultural quarter in Glasgow North, with urban boosters envisioning the unlikely, rundown and de-populated light industrial estate as a key site in the city's ongoing cultural regeneration strategy. Yet this creative place-making initiative, I argue, masks a post-political conjuncture based on urban speculation, displacement and the foreclosure of dissent. Post-politics at Speirs Locks is characterised by what I term ‘soft austerity urbanism’: seemingly progressive, instrumental small-scale urban catalyst initiatives that in reality complement rather than counter punitive hard austerity urbanism. Relating such processes of soft austerity urbanism to a wider context of state-led gentrification, this study contributes to post-political debates in several ways. Firstly, it questions demands for participation as a proper politics when it has become practically compulsory in contemporary biopolitical capitalism. Secondly, it demonstrates how an extreme economy of austerity urbanism remains the hard underside of post-political, soft austerity urbanism approaches. Thirdly, it illustrates how these approaches relate to wider processes of ‘real abstraction’ – which is no mere flattery of the mind, but instead is rooted in actually existing processes of commodity exchange. Such abstraction, epitomised in the financialisation and privatisation of land and housing, buttresses the same ongoing property dynamics that were so integral to the global financial crisis and ensuing austerity policies in the first place. If we aim to generate a proper politics that creates a genuine rupture with the destructive play of capital in the built environment, the secret of real abstraction must be critically addressed

Analyse experimentale du R1234yf comme frigorige`ne de remplacement immediat du R134a dans un systeme a` compression de vapeur

[EN] This paper presents an experimental analysis of a vapor compression system using R1234yf as a drop-in replacement for R134a. In this work, we compare the energy performance of both refrigerants, R134a and R1234yf, in a monitored vapor compression system under a wide range of working conditions. So, the experimental tests are carried out varying the condensing temperature, the evaporating temperature, the superheating degree, the compressor speed, and the internal heat exchanger use. Comparisons are made taking refrigerant R134a as baseline, and the results show that the cooling capacity obtained with R1234yf in a R134a vapor compression system is about 9% lower than that obtained with R134a in the studied range. Also, when using R1234yf, the system shows values of COP about 19% lower than those obtained using R134a, being the minor difference for higher condensing temperatures. Finally, using an internal heat exchanger these differences in the energy performance are significantly reduced.This study was sponsored by Fundacio Caixa Castello-Bancaixa under the project P11B2010-24 "Aplicacion de nuevos refrigerantes con bajo potencial de efecto invemadero en sistemas de frio comercial y climatizacion".Navarro Esbri, J.; Mendoza Miranda, JM.; Mota Babiloni, A.; Barragán Cervera, Á.; Belman Flores, JM.
