Located on the Iberian Mediterranean coast, El Collado is an open-air site where a rescue excavation was conducted over two seasons in 1987 and 1988. The archaeological work excavated surface area of 143m2 14 burials were discovered, providing skeletal remains from 15 individuals. We have obtained AMS dates for 10 individuals by means direct dating human bones. ranges probability distribution calibrated suggest that cemetery used during long period time (781–1020 years at 95.4%). new...
Navigation in the Mediterranean Neolithic is studied here through boats that were used, degree of technical specialisation their construction and, above all, chronology. After a brief explanation exceptional site La Marmotta, characteristics and chronology five canoes found at settlement one nautical objects linked to Canoe 1 are discussed. This will allow reflection on capability societies for navigation owing high technological level. technology was an essential part success expansion,...
Abstract The Centro Nacional de Aceleradores is a user-oriented accelerator facility in Seville, Spain. Its main facilities are 3 MV tandem accelerator, an 18 MeV proton Cyclotron, tandetron used for AMS, compact radiocarbon measurements, $$^{60}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mrow/> <mml:mn>60</mml:mn> </mml:msup> </mml:math> Co irradiator and PET/CT scanner. technical specifications research applications of these described.

In September 2005, an accelerator mass spectrometry (AMS) system based on a 1MV Tandetron arrived at the Centro Nacional de Aceleradores (CNA). One of main research programs for this AMS facility is radiocarbon. At same time as was installed and tested, 14 C sample preparation laboratory designed set up. A graphitization line that allows 5 samples in parallel built October 2006. The first months were mainly dedicated to check optimize all processing. For such task, several reference have...
Abstract This paper evaluates the complexities of radiocarbon ( 14 C) dates from soil organic matter (SOM) in archaeological scenarios. The aqueous NaOH-insoluble residual SOM Neolithic to medieval sites NW Spain produced consistently older calibrated C ages than NaOH-extractable SOM. Using pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and thermally assisted hydrolysis methylation (THM-GC-MS), we analyzed molecular composition these fractions, aiming understand differences gain...
The Mexico City Metropolitan Area (MCMA) produces a complex mixture of gases and aerosols from diverse sources, including burning fossil fuels, biomass, wastes, with significant biogenic contribution. We present the first results ongoing projects to study temporal spatial variations 14 CO 2 in area. Temporal reconstructed tree rings Taxodium mucronatum indicate considerable radiocarbon depletion, accordance vast amount fuels burnt inside Valley, values between 62 246‰ lower than background...
Abstract To draw the balance of anthropogenic 129 I input into European soils, concentrations and 127 in seven soils from Lower Saxony were analyzed down to a depth 250 cm. In comparison with pre-nuclear Ukrainian we detected significant I. Considering different time periods for it was possible assess dynamics sorption processes which dominate migration accumulation. Anthropogenic successfully used as tracer clarification trace elements soils.
Abstract Romero I. and Santos F. J. (2007) Firm size regional linkages: a typology of manufacturing establishments in southern Spain, Regional Studies 41, 571–584. Regions with different levels development are characterized by enterprise compositions according to firm productive linkages. Using these two variables additional ones – the technological level position value chain composition industrial sector any region can be studied. In this respect, new theoretical is proposed paper as...
