La transición de fase I4/mcm→Pm3m en Sr0.5Ba0.5HfO3-δ

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2001
The effect of partial substitution of cations in AMO3 compounds have been studied because the physical properties and applications of these materials can be improved. In particular we are interested in the Sr1-xBaxHfO3 family.

How to Estimate Unbiased and Consistent input-output Multipliers on the Basis of use and Make Matrices [PDF]

open access: yes
In the literature, the construction of technical coefficients is linked to flow data (use and make matrices), but stochastics are imposed on the coefficients when multipliers are calculated, by means of the Leontief inverse.

Análisis de la resistencia a la corrosión de barras corrugadas de acero inoxidable en medios acuosos que simulan el hormigón

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2004
The corrosion behaviour of stainless steel reinforced bars used in civil engineering was studied. Different electrochemical tests were performed using several stainless steel bars (austenitic and duplex), hot and cold rolled, in the presence of a ...

Knowledge in the air and cooperation between firms: Traditions of secrecy and the reluctant emergence of specialization in the ceramic manufacturing district of Lampang, Thailand [PDF]

open access: yes
In the study of industrial clusters, the relative importance, and possible interrelationship, of inter-firm cooperation in production and broad knowledge transfers (both unintentional spillovers and intentional sharing) have long been disputed.
