The author proposes a comparative study in the frame of a macroarea formed by the south European countries. He points out the characteristics and difficulties of the liberal state establishment in the Mediterranean countries. At the same time he underlines the new importance of the intellectuals roll as one of the main consequences of that crisis.

El mes de setembre de 1993, el departament d'Història Contemporània de la Universitat de Barcelona i l'european Network for Women's Studies (ENWS) del Consell d'Europa van organitzar el congrés internacional "De la dictadura a la democràcia: les dones en l'Europa mediterrània central i de l'est". Lóbjectiu del congrés va ser desenvolupar una reflexió entorn de la trajectòria de les dones en les crisis dels antics règims dictatorials i en la transició democràtica.

No es exagerado afirmar que, en las últimas décadas, los estudios dedicados a la cultura material de la antigüedad tardía y, en particular, a sus producciones cerámicas, han experimentado un desarrollo acelerado. Este fenómeno se ha traducido en una auténtica explosión de títulos que, con diversa extensión y profundidad, abarcan todas las posibilidades de análisis: desde las monografías de excavación, en las que se describen los repertorios asociados a las formas de vida y trabajo de un asentamiento, hasta las síntesis regionales que abordan cuestiones relacionadas con los mecanismos económicos, culturales y políticos que impulsaron la creación de unos circuitos de intercambio de alcance mediterráneo.

Même si les données disponibles pour le Gravettien méditerranéen ibérique sont réduites et dans des contextes stratigraphiques mal définis, nous présentons dans ce travail les révisions de quelques sites majeurs (Reclau Viver, l"Arbreda, Parpalló, Malladetes, Beneito et Cendres ainsi que de quelques autres gisements. La vision globale du Gravettien méditerranéen ibérique nous montre, dans la période ancienne, une faible présence mais une industrie lithique et osseuse très classique est observée dans les phases moyenne et finale de la période.

Leaf litter inputs and retention play an important role in ecosystem functioning in forested streams. We examined colonization of leaves by microbes (bacteria, fungi, and protozoa) and fauna in Fuirosos, an intermittent forested Mediterranean stream. Black poplar (Populus nigra) and plane (Platanus acerifolia) leaf packs were placed in the stream for 4 mo. We measured the biomasses and calculated the densities of bacteria, fungi, protozoa, meiofauna, and macroinvertebrates to determine their dynamics and potential interactions throughout the colonization process. Colonization was strongly correlated with hydrological variability (defined mainly by water temperature and discharge). The 1st week of colonization was characterized by hydrological stability and warm water temperatures, and allocation of C from microbial to invertebrate compartments on the leaf packs was rapid. Clumps of fine particulate organic matter (FPOM) were retained by the leaf packs, and enhanced rapid colonization by microfauna and meiofaunal collector-gatherers (ostracods and copepods). After 2 wk, an autumnal flood caused a 20-fold increase in water flow. Higher discharge and lower water temperature caused FPOM-related fauna to drift away from the packs and modified the subsequent colonization sequence. Fungi showed the highest biomass, with similar values to those recorded at the beginning of the experiment. After 70 d of postflood colonization, fungi decreased to nearly 40% of the total C in the leaf packs, whereas invertebrates became more abundant and accounted for 60% of the C. Natural flood occurrence in Mediterranean streams could be a key factor in the colonization and processing of organic matter.

Se describen tres tipos principales de acumulaciones salinas a partir de la interpretación de los perfiles de sísmica de reflexión de las campañas ENIEPSA-MAP-77 (1977) y WESTERN GEOPHYSICAL COMPANY OF AMERICA-MEDS (1973) en el sector norte del surco de Valencia. Los principales tipos de estructuras salinas son rollers de sal, almohadillas y diapiros que se disponen en tres cinturones paralelos al límite de la sal messiniense.

En aquest article es revisen els components de la fertilitat dels sòls mediterramis i es discuteix les seves característiques generals, així com la suposada oligotrofia que sovint se'ls ha atribuït. La tipologia d'aquests sòls i els cicles del N i P presenten alguns trets comuns que vénen determinats per trobar-se en n règim de clima mediterrani, tanmateix existeixen diferències remarcables que es relacionen, sobretot, amb el tipus de roca mare i que expliquen les diferències sovint atribuïdes als sòls de les cinc regions mediterrànies

Tropical irradiations into Mediterranean nitrophilous vegetation. Irradiations of pantropical Ruderali-Manihotetea reach Mediterranean countries. Hygronitrophilous Ecliption prostratae, trodden and disturbed ground-colonizing Eleitsinion indicae and suburban Lycio-Ipomoeion curtain communities are specially examined.

A prior long-term and complex evaluation of the already available data on the geophysical prospecting during the first season work carried out at 2006, at the archaeological site of Tchinguiz Tepe of Termez, took place to decide the strategy to follow during the campaign of 2007. This previous evaluation of the information, on one hand, leaded to the decision to increase the geophysical prospecting at Tchinguiz Tepe, on the other hand, to decide the exact location of areas where the archaeological interventions.would carry out. The main objective at the beginning of this new season was to crosscheck the reliabilityof the measurements and, at the same time, to establish the unknown up to the present archaeologicaland chronological sequence of Tchinguiz Tepe. Meanwhile, the geophysical prospecting also wasextended to the outskirts of the city were the localisation of an unknown up to now Buddhist Monasterywas possible.
