Research paper thumbnail of REMOTE SENSING MODELLING AND MONITORING OF WATER QUALITY WITHIN THE SEVILLE (SPAIN) AREA DAMS

The proposed project looks at the modelling and spatial-temporal assessment of water quality within the Seville area dams through the use of the hyperspectral and multi-angular capabilities of the CHRIS sensor in the water configuration (Mode 2).

Research paper thumbnail of Interaction of dexamethasone and montmorillonite — Adsorption-degradation process

The dexamethasone content, as determined by high-pressure liquid chromatography (HPLC), rapidly decreases from 50 to 4.7 μg/ml after 24 h, and then remains almost constant during 168 h. The first stage of the decomposition is mainly consistent with an adsorption process, while the second one is characterized by a slow degradation of dexamethasone remaining in solution.X-ray diffraction (XRD) and infrared (IR) studies showed the presence of dexamethasone molecules adsorbed in the interlayer space of montmorillonite, with the basal spacing being consistent with an orientation of the plane of the rings parallel to that of the silicate sheets. Desorption studies showed a slow release of the dexamethasone from the interlayer space of montmorillonite.

Not far off is the issue of the changing role of monuments in the making and maintaining of key cultural devices such as memory and identity. Addressing both these highly-debated issues from a science-based perspective, in this paper we look at an unusual case study set in southern Iberia and illustrate how these archaeological questions can benefit from robust materials-science approaches.

We present the contextual, morphological and analytical study of an exceptional Early Iron Age hoard composed of a number of different (and mostly exotic) materials such as amber, quartz, silver and ceramic. This hoard, found under the fallen orthostat of a megalithic structure built at least 2000 years earlier, throws new light on long-distance exchange networks and the effect they could have had on the cultural identities and social relations of local Iberian Early Iron Age communities. Moreover, the archaeometric study reveals how diverse and distant the sources of these item are (Northern Europe to Eastern and Western Mediterranean raw materials, as well as local and eastern technologies), therefore raising questions concerning the social mechanisms used to establish change and resistance in contexts of colonial encounter.
