We apply a gravity model to 1980–1996 annual nonfuel imports data for 58 Blazer Nike countries to quantify the effects of recently created or revamped PTAs on trade. We modify the gravity equation to identify separate effects of PTAs on intrabloc trade, members’ Chaussure Nike Blazer Noir total imports and their total exports and to test for significant changes in trade patterns following the creation of trade blocs. We find no indication that ‘new regionalism’ boosted intrabloc trade significantly and we find Basket Nike Blazer Femme trade diversion only for the EU and EFTA. The latter also exhibit ‘export diversion’, which could indicate their imposing welfare costs on other countries. Latin American trade liberalization in the 1990s had a positive impact on bloc members’ imports and, usually, exports.
New relationships between grain size and relative density have been established for the case of solid-state sintering of ceramic powders. These new expressions have been used to fit experimental points, obtained during solid-state sintering of a pure submicronic α-alumina powder shaped by slip casting. In contrast to what was established in the past, it is shown that densification is controlled by grain boundary diffusion and grain growth is controlled by the grain boundaries. The quality of the green state (homogeneity of the pore size and homogeneity of the spatial distribution of pores) is used to explain the difference between the results reported here and previous results, where diffusion at the surface of the pores was claimed to control grain growth.
