The environmental Kuznets curve within European countries and sectors: greenhouse emission, production function and technology
2018
Based on the environmental Kuznets curve (EKC) hypothesis and the technological change and the environment literature, our original contribution consists in analysing within the decomposition model the direct and indirect influence of technological change as well as the energy mix on CO2 emissions. Focusing on the dirtiest sectors of 25 EU countries in the period 1997-2005 and considering the endogeneity issue, we estimate an adjusted EKC relationship comparing a single equation model (univariate model) with a simultaneous equations system (bivariate model). Following Lopez (J Environ Econ Manag 27:163-184, 1994), a second equation is introduced where per capita income is a positive functio…
Characterization of a fiber-reinforced new fully aromatic liquid crystalline polymer
1998
A new rigid liquid crystalline polymer that demonstrates good mechanical and thermomechanical properties and acceptable processing temperature has been recently synthesized and characterized. The melting temperature and some thermomechanical properties do not seem, however, suitable for use in some applications at high temperature or in the presence of aggressive fluids. The use of appropriate inorganic fillers can overcome these shortcomings. In this work the new LCP, polymerized in a bench-scale apparatus, and the same sample filled with carbon fibers are characterized. The properties of the carbon fiber filled LCP are compared with those of another filled wholly aromatic commercial LCP,…
