Major palaeohydrographic changes in Alpine foreland during the Pliocene - Pleistocene
2008
International audience; The changing palaeogeographical pattern of Alpine deposits across the European forelands can be traced by identifying mineral assemblages and establishing the chronology of Pliocene-Pleistocene deposits in Alpine foreland. In the late Miocene, the upper courses of the Rhine and the Aar flowed east from the Swiss molasse plain towards the Danube. In the early Pliocene (Brunssumian, 5-3.2 Ma), these same rivers headed north-wards towards the Rhine Graben of Alsace. In the early Reuverian, these streams were captured south of the Rhine Graben by the Doubs. They ceased their northward flow and headed west to feed the Bresse Graben. This phase is dated to the Lower and Mi…
Mid-Holocene vegetation dynamics in the Tejo River estuary based on palaeobotanical records from Ponta da Passadeira (Barreiro-Setúbal, Portugal)
2014
This paper presents the results of pollen and charcoal analyses carried out in the sedimentary formation of Ponta da Passadeira, south of the Tejo River estuary, Portugal. The data provide information regarding the evolution of the coastline and ecosystem of the estuary during the mid and late Holocene. The study focuses on a group of upright woody fossilized tree remains that, together with those identified earlier by Garcia-Amorena et al. (2007), form part of the fossil forest of Ponta da Passadeira. Eight remains were identified as Pinus pinaster, four as Pinus pinea and one as Pinus sp. Two specimens of these species were dated to 6523 and 5805 cal. a BP. Pollen analysis was undertaken …
La prehistoria de Ibiza y Formentera: estado actual de la investigación
1988
The study of the prehistory of Ibiza and Formentera, the two small islands that form the Pityussae sub-group within the Balearic archipelago, began a few years ago as a consequence of the discovery and excavation of the megalithic chamber tomb of a Ca Na Costa on Formentera. Before then, prehistorians were still in doubt as to whether these islands had been occupied before the Phoenician colonisation. Many sites have come to light in the last decade, allowing us to present for the first time a general survey of the prehistoric settlement of the islands. Nevertheless, many problems are still unsolved, and new excavations are needed to establish the apparently complex cultural sequence, which…
Las ánforas de Brindisi en Hispania Citerior. Pautas de distribución y consumo
2017
La presencia del ejército romano republicano en la Hispania Citerior ha sido difícil de reconocer en el pasado debido al error en la interpretación de algunos yacimientos y la falta de investigación sobre el tema. En los últimos años, se han realizado nuevas investigaciones sobre yacimientos romanos republicanos identificando pequeñas fortificaciones militares y asentamientos civiles itálicos relacionados con el ejército. Uno de los fósiles directores presentes en todos estos yacimientos es la cerámica itálica tanto fina como común y las ánforas. Precisamente, las ánforas de la Apulia constituyen uno de los fósiles directores poco estudiados; este artículo pretende llenar este vacío y mostr…
Indigenismo y migracionismo. Aspectos de la neolitización en la fachada oriental de la Península Ibérica
1996
This paper discusses various aspects on the origins of the Neolithic in the Iberian Peninsula. The dual model is proposed as an alternative to the dichotomy of demie (migrationist) and non-demic (indigenist) explanations. The application of this model in eastern Spain offers an opportunity to evaluate its potential to account for diversity in processes associated with the origins of food production and their spatial organisation.
BIM Modelling of Ancient Buildings
2018
In the last years, new procedures on design and management of constructions, based on 3D standardised models of building elements, have been proposed. It’s the case of Building Information Modelling (BIM) applications, that, differently from CAD ones, allow to work with libraries of 3D parametrical objects (smart objects) describing geometric, structural and material properties of building elements. This methodology is based on the Industry Foundation Classes (IFC) model, that represents a global standard for the building data exchange. Initially used for the design of new architectures, BIM methodology has been even more considered also for the management and the conservation of historical…
Measurements of aerosol and CCN properties in the Mackenzie River delta (Canadian Arctic) during spring–summer transition in May 2014
2018
Within the framework of the RACEPAC (Radiation–Aerosol–Cloud Experiment in the Arctic Circle) project, the Arctic aerosol, arriving at a ground-based station in Tuktoyaktuk (Mackenzie River delta area, Canada), was characterized during a period of 3 weeks in May 2014. Basic meteorological parameters and particle number size distributions (PNSDs) were observed and two distinct types of air masses were found. One type were typical Arctic haze air masses, termed accumulation-type air masses, characterized by a monomodal PNSD with a pronounced accumulation mode at sizes above 100 nm. These air masses were observed during a period when back trajectories indicate an air mass origin in the north-e…
Confident methods for the evaluation of the hydrogen content in nanoporous carbon microfibers
2012
Abstract Nanoporous carbon microfibers were grown by chemical vapor deposition in the vapor-liquid solid mode using different fluid hydrocarbons as precursors in different proportions. The as-grown samples were further treated in argon and hydrogen atmospheres at different pressure conditions and annealed at several temperatures in order to deduce the best conditions for the incorporation and re-incorporation of hydrogen into the microfibers through the nanopores. Since there are some discrepancies in the results on the hydrogen content obtained under vacuum conditions, in this work, we have measured the hydrogen content in the microfibers using several analytical methods in ambient conditi…
Mineral control of arsenic content in thermal waters from volcano-hosted hydrothermal systems: Insights from island of Ischia and Phlegrean Fields (C…
2006
This paper documents arsenic concentrations in 157 groundwater samples from the island of Ischia and the Phlegrean Fields, two of the most active volcano-hosted hydrothermal systems from the Campanian Volcanic Province (Southern Italy), in an attempt to identify the environmental conditions and mineral-solution reactions governing arsenic aqueous cycling. On Ischia and in the Phlegrean Fields, groundwaters range in composition from NaCl brines, which we interpret as the surface discharge of deep reservoir fluids, to shallow-depth circulating fluids, the latter ranging from acid-sulphate steam-heated to hypothermal, cold, bicarbonate groundwaters. Arsenic concentrations range from 1.6 to 690…
Morphological and molecular characterization of three new parastenocarididae (Copepoda: Harpacticoida) from caves in Southern Italy
2020
We describe three new parastenocaridid: Cottarellicaris sanctiangeli Bruno & Cottarelli sp. nov., Stammericaris vincentimariae Bruno & Cottarelli sp. nov. and Proserpinicars specincola Bruno & Cottarelli sp. nov., collected in the pools of five different caves located in Calabria (Southern Italy). We conducted a phylogenetic analysis based on the mitochondrial COI and ribosomal 18S sequences of C. sanctiangeli sp. nov. and S. vincentimariae sp. nov., and of four more species of Stammericaris and one Proserpinicaris available from literature. Based on the molecular study, the specimens of C. sanctiangeli sp. nov. are clearly separated from the species belonging to the closely-rel…
