Los insectos pueden detectar la presencia de un cadáver a gran distancia, colonizándolo rápidamente y siendo los primeros en explotar este recurso. La composición y dinámica de la comunidad, junto con su presencia en un lugar específico, son clave para su posterior aplicación forense. Por este motivo, se estudió la fauna entomosarcosaprófaga asociada a un cadáver en una zona montañosa de la provincia de Murcia (SE, España). Las especies Chrysomya albiceps, Calliphora vicina y C. vomitoria fueron las especies más valiosas como indicadores estacionales. Estas especies, junto con Dermestes frischii, Camponotus sylvaticus y la superfamilia Chalcidoidea, definen un patrón claro de colonización que varía según la estación del año. Finalmente, la especies Iberoformica subrufa pueden tener valor potencial como indicador de hábitat del área estudiada.

For this reason, it was studied the entomosarcosaprophagous fauna associated with a carcass in a wild mountainous area of the province of Murcia (SE, Spain). The species Chrysomya albiceps, Calliphora vicina and C. vomitoria were the most valuables species as seasonal indicators. These species, together with Dermestes frischii, Camponotus sylvaticus and those of the Chalcidoidea superfamily, define a clear pattern of colonization that varies according to the season of the year. Finally, the species Iberoformica subrufa may be of potential use as habitat indicator of the studied area.

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.

The properties of metal/semiconductor interfaces have received considerable attention over the past few years, and the Al/GaAs system is of special interest because of its potential use in high-speed logic integrated optics, and microwave applications. For such materials a detailed knowledge of the geometric and electronic structure of the interface is fundamental to an understanding of the electrical properties of the contact. It is well known that the properties of Schottky contacts are established within a few atomic layers of the deposited metal. Therefore surface contamination can play a significant role. A method for fabricating contamination-free interfaces is absolutely necessary for reproducible properties, and molecularbeam epitaxy (MBE) offers such advantages for in-situ metal deposition under UHV conditions
