Determinación de la presencia de fatiga mecánica en materiales cerámicos

Boletín de la Sociedad Española de Cerámica y Vidrio, 1999
It is well known that ceramic materials are highly susceptible to environmental assisted subcritical crack growth. In addition, this subcritical crack growth could be also related to cyclic loading (mechanical fatigue).

Rise of the south: How Arab‐led maritime trade transformed China, 671–1371 CE

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 3-38, March 2025.
Abstract China's center of socioeconomic activities was in the North prior to the Tang dynasty but is in the South today. We demonstrate that Arab and Persian Muslim traders triggered that transition when they came to China in the late seventh century, by lifting maritime trade along the South Coast and re‐creating the South.

Modulación composicional en la perovskita “PbCrO₃” y su influencia en las propiedades

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
In this work, we revisited the “PbCrO3” perovskite. In the late 60’s, it was claimed to be cubic and a G-type antiferromagnetic material (1, 2). We have encountered that an intrinsic compositional modulation is present and shows a deficiency in lead of ...

Defining the geographical level of competition: a taxonomy of industry tradability

Economica, EarlyView.
Abstract The paper develops a taxonomy of industry tradability to define the geographical level at which competition takes place. First, it creates a novel dataset that combines production and international trade data for both goods and services industries, defined at a detailed (3‐digit) level of industry aggregation for 15 European countries.
