It has been reported([1]) that when a loosely packed column of saturated sand in a vertical cylindrical container is shock loaded axially by dropping to the floor, large horizontal cracks initiate, grow and eventually fade away in the sand as it settles under gravity. This paper shows that a similar phenomenon can also be observed when shock loading is replaced by forcing water to percolate upward through the sand column. It is believed that our result sheds further light on the physics of formation of these cracks.

As part of a study of the wear of candidate heat exchanger tube materials for use in fluidized bed combustors, two similar laboratory-scale rigs have been built and characterized. Specimens of selected alloys are carried on counter-rotating rotors immersed in a fluidized bed, and are exposed to particle impact velocities of up to approximately 3 ms-1 at temperatures up to 1000°C. The performance of this design of apparatus has been investigated in detail. The effects of several experimental variables have been studied, including angle of particle impact, specimen speed, position of the rotor within the fluidized bed, duration of exposure, bed material particle size, degradation of the bed material, degree of fluidization of the bed, and size of specimen. In many cases the results obtained with steel specimens at elevated temperatures are similar to those observed with polymeric specimens at low temperatures.

Resumen: El texto realiza una relectura del método Ver-Juzgar-Actuar teniendo en cuenta el acercamiento biográfico que ofrecen las ciencias sociales. Propone considerar que la Teología Pastoral desarrolla así un discurso sobre la Iglesia, la Academia y la Plaza Pública en el cruce que estos ámbitos tienen en las mismas prácticas cristianas, dando lugar a una Teología Inter Loci. Y describe el perfil teológico emergente en dicha experiencia utilizando el marco de las inteligencias múltiples.
