Étude typologique, technologique et culturelle de la céramique du Petit-Paulmy à Abilly (Indre-et-Loire)
2009
Anhand einer qualitativen und quantitativen Studie wurden die minimale und die maximale Anzahl der dem Endneolithikum zugeordneten Keramikindividuen ermittelt. Der Corpus umfasst drei typologische und technische Gruppen, die drei chronologischen und kulturellen Phasen entsprechen. Eine Quantifizierung der unterschiedlichen Formen vermittelt ein Bild des endneolithischen Keramikrepertoires des Fundplatzes. Der für die Herstellung der Keramik benutzte Ton ist lokaler Herkunft. Es existiert eine Korrelation zwischen der Dicke der Wandung, der Form der Gefäße und den unterschiedlichen Herstellungstechniken (Glättung, Schaben, Schlagen, Kieselglättung). Die Gefäße der drei Hauptformen wurden in …

Radiation hard monolithic CMOS sensors with small electrodes for High Luminosity LHC
2019
Abstract The upgrade of the tracking detectors for the High Luminosity-LHC (HL-LHC) requires the development of novel radiation hard silicon sensors. The development of Depleted Monolithic Active Pixel Sensors targets the replacement of hybrid pixel detectors with radiation hard monolithic CMOS sensors. We designed, manufactured and tested radiation hard monolithic CMOS sensors in the TowerJazz 180 nm CMOS imaging technology with small electrodes pixel designs. These designs can achieve pixel pitches well below current hybrid pixel sensors (typically 50 × 50 μ m ) for improved spatial resolution. Monolithic sensors in our design allow to reduce multiple scattering by thinning to a total si…
Captación y selección de materias primas en la primera metalurgia del Sureste de la península ibérica
2020
The authors are grateful for the technical and human support provided by SGIker of UPV/EHU and European funding (ERDF and ESF). We are also in debt with Eduardo Galán, Ruth Maicas and Carmen Cacho, curators of the Museo Arqueológico Nacional (Madrid) for facilitating the sampling and study of metal objects as well as with Ignacio Soriano Llopis for his help on the selection and sampling of the Palmela points, with Massimo Chiaradia who performed the analyses of the Palmela points at the Department of Earth Sciences (University of Geneva, Switzerland) and with Óscar García Vuelta for his pictures of some assemblages. We also appreciate and the careful work of editing and style of the TP edit…
Intertidal epilithic bacteria diversity changes along a naturally occurring carbon dioxide and pH gradient.
2014
Intertidal epilithic bacteria communities are important components of coastal ecosystems, yet few studies have assessed their diversity and how it may be affected by changing environmental parameters. Submarine CO2 seeps produce localised areas of CO2-enriched seawater with reduced pH levels. We utilised the seawater pH/CO2 gradient at Levante Bay (Italy) to test the hypothesis that epilithic bacteria communities are modified by exposure to seawater with the varying chemical parameters. Biofilms were sampled from three sites exposed to seawater with different pH/CO2 levels and diversity determined using high-throughput sequencing of 16S rRNA genes. Seawater pCO2 concentrations were increase…
A funerary perspective on the Bell Beaker period in the Wester Mediterranean Reading the social context of individual burials at La Vital (Gandia, Va…
2013
[EN] The discussion about social dynamics in recent Pre- history is supported by the study of funerary practices. The presence and significance of individual and collec- tive burials in Final Neolithic/Chalcolithic societies in the southeast of the Iberian Peninsula provides new evi- dence for the debate concerning the emergence of social inequalities in this region. Our contribution is based on the recent discovery and excavation of several individual pit burials in domestic contexts at the site of La Vital (Gandía, Valencia). The particularities of the identified burials (different ritual episodes) and their content (Bell Beaker pottery, metal objects, animal offerings) together with an …
Revisiting the Epipalaeolithic-Neolithic Transition in the Extreme NW of Africa : The Latest Results of the Chronological Sequence of the Cave of Kaf…
2021
[EN] This study focuses on the chronostratigraphic sequence of the Cave of Kaf Taht el-Ghar (Dar Ben Karrich, Tétouan, Morocco) excavated in 2012 in the framework of the AGRIWESTMED research project. The broad sequence reveals a series of occupations ranging from the Pleistocene (Moroccan Aterian) to recent historical times. Our research identifies a rich Early Neolithic phase (sixth millennium cal BC) containing the earliest pottery and domesticated animal and plant remains in the western Maghreb. However, this Early Neolithic level is not an immediate successor of the last traces of the Epipalaeolithic hunter-gatherer occupation, which started at the end of the Younger Dryas (10,900–9700 …
Estudio de la fauna del nivel IV del Abrigo de la Quebrada y su aportación al conocimiento de la economía y el comportamiento humano en el Paleolític…
2019
El Abrigo de la Quebrada (Chelva, Valencia) es un yacimiento con varios niveles de ocupación neandertal. El nivel IV, con dos dataciones de 43.930 ± 750 BP (Beta-244002) y >50,6 ka BP (OxA-24855), se caracteriza por su estructura de palimpsesto y la elevada densidad de restos arqueológicos (industria lítica, fauna, carbones y estructuras de combustión). El conjunto óseo se compone de 100.907 restos, con una mayor presencia de las familias Bovidae, Equidae, Cervidae y Testudinidae. La presencia de fracturas frescas, muescas de percusión y marcas de corte confirman el carácter antrópico de la muestra, así como las termoalteraciones. Dada la elevada fragmentación de la muestra (1% de identific…
Neolithic Human Societies and Woodlands in the North-Western Mediterranean Region: Wood and Charcoal Analysis
2017
An overview of woodland history in the north-western Mediterranean region, based on charcoal analysis (Anthracology) from Mesolithic and Neolithic sites, is proposed for the Mediterranean areas of France, Spain and Portugal. The taxonomic identification of charcoal fragments and the diachronic variations of taxa frequencies provide, for each settlement, an accurate image of the local vegetal cover. During the end of the last glaciation, beginning of the Holocene, vegetation dynamics reflects the evolution of climatic and geographic conditions. Any potential ecological impact by hunter-fisher-gatherer communities (Mesolithic) remains invisible; the same comment applies to the farming-herding…
Les Campaniformes dans le sud-est de la France
2004
The term "Bell Beaker", in the strict sense, designates a ceramic beaker form with an S-shaped profile that gives it the shape of an inverted bell. This type of drinking-vessel is characterized by both its very particular pattern of decoration and by the generally skilled execution of that decoration. By extension, the decoration characteristic of these beakers bas allowed the expansion of the category "Bell-Beaker" to include other pottery forms and even other types of decoration showing the same tradition, vvhich probably represent an evolution or reproduction of the original Bell Beaker pattern, The recognition of these objects and their definition as a class date to the nineteenth centu…
