Habitat et pratiques domestiques des Ve-IVe s. a.v. J.-C. dans la ville de Lattes

Les recherches menées ces dernières années sur le site de Lattes ont livré une documentation abondante sur l’architecture et l’organisation de l’espace domestique du ve s. et surtout du ive s. av. J.-C. C’est en effet durant cette période qu’a eu lieu la mise en place de la trame urbaine de la ville qui, dans ses grandes lignes, perdurera jusqu’à la fin de l’occupation protohistorique du site ; de même, c’est à ce moment qu’apparaissent des techniques de construction dont certaines sont exclusives de ces périodes, mais qui pour d’autres resteront en vigueur jusqu’à la Protohistoire récente. Cet article présente une synthèse de nos connaissances sur cette phase ancienne, en insistant sur les permanences, les modifications ou les évolutions dans l’architecture, la typologie des maisons et les pratiques domestiques au cours de ces étapes et par rapport aux étapes postérieures.

Ancient DNA analysis of 8000 B.C. near eastern farmers supports an early neolithic pioneer maritime colonization of Mainland Europe through Cyprus and the Aegean Islands

The genetic impact associated to the Neolithic spread in Europe has been widely debated over the last 20 years. Within this context, ancient DNA studies have provided a more reliable picture by directly analyzing the protagonist populations at different regions in Europe. However, the lack of available data from the original Near Eastern farmers has limited the achieved conclusions, preventing the formulation of continental models of Neolithic expansion. Here we address this issue by presenting mitochondrial DNA data of the original Near-Eastern Neolithic communities with the aim of providing the adequate background for the interpretation of Neolithic genetic data from European samples. Sixty-three skeletons from the Pre Pottery Neolithic B (PPNB) sites of Tell Halula, Tell Ramad and Dja'de El Mughara dating between 8,700-6,600 cal. B.C. were analyzed, and 15 validated mitochondrial DNA profiles were recovered. In order to estimate the demographic contribution of the first farmers to both Central European and Western Mediterranean Neolithic cultures, haplotype and haplogroup diversities in the PPNB sample were compared using phylogeographic and population genetic analyses to available ancient DNA data from human remains belonging to the Linearbandkeramik-Alföldi Vonaldiszes Kerámia and Cardial/Epicardial cultures. We also searched for possible signatures of the original Neolithic expansion over the modern Near Eastern and South European genetic pools, and tried to infer possible routes of expansion by comparing the obtained results to a database of 60 modern populations from both regions. Comparisons performed among the 3 ancient datasets allowed us to identify K and N-derived mitochondrial DNA haplogroups as potential markers of the Neolithic expansion, whose genetic signature would have reached both the Iberian coasts and the Central European plain. Moreover, the observed genetic affinities between the PPNB samples and the modern populations of Cyprus and Crete seem to suggest that the Neolithic was first introduced into Europe through pioneer seafaring colonization.

Iltirta y Auso, dos "capitales" regionales en al Hispania republicana

Estudio sobre el papel desempeñado por las ciudades ibéricas de Iltirta y Auso en la primera organización territorial romana de Hispania, en especial durante el siglo II a. de C. Ambos fueron importantes centros de carácter regional; el análisis de los contextos grecoromanos, la numismática y los escasos restos arqueológicos conocidos así lo confirman. En realidad, el proceso fue la continuación de una realidad ya preexistente con anterioridad a la conquista romana.

Instalaciones oleícolas y vinícolas estudiadas en el marco del Proyecto Ager Tarraconensis (PAT)

Dentro del Proyecto Ager Tarraconensis, se han estudiado en el Camp de Tarragona 19 yacimientos con indicios de instalaciones de producción de aceite o vino, que se centran especialmente entre los siglos I a.C. y II d.C. También se han estudiado 22 yacimientos con indicios de alfarería, en siete de los cuales se conoce la producción de ánforas vinarias. El hallazgo de diversas marcas de alfarero dónde identificamos el nombre de M. Clodius Martialis apunta hacia una rica familia de la elite de Tarraco, con la que se han relacionado cuatro yacimientos y quizás un quinto. Entre la época de Augusto y el siglo III, el vino se confirma como el producto principal de una agricultura desarrollada dentro del sistema de la villa, enfocada al mercado de ultramar. El aceite se debió producir para el consumo local. Esta región no volvió a potenciar la producción de vino a nivel de gran negocio de ámbito internacional hasta el siglo XVIII, con el cual se establece una comparación.

La Religió ibèrica en el territori de la Indigècia

Aquest treball parteix de la pregunta: quines eren les característiques principals de la religió ibèrica? A partir d’aquesta pregunta, n’han sorgit d’altres que han permès concretar aspectes més específics de la religió en aquest territori: quins llocs de culte utilitzaven?, quines divinitats veneraven?, qui s’encarregava de dur a terme el culte?, com es manifestava aquesta religió?, creien en el més enllà?, quins ritus o pràctiques cultuals realitzaven?

Obispos y gladiadores: El recurso a los profesionales del anfiteatro en disputas por la elección episcopal.

[spa]La costumbre de enrolar a combatientes del anfiteatro (arenarii) como guardia personal en el marco de luchas faccionales sobrevivió durante el siglo IV. Incluso si en la mayor parte de casos este fenómeno se explica por razones políticas, conocemos dos ejemplos en los que los candidatos a obispo recurrieron a gladiadores para triunfar sobre sus oponentes. El primer ejemplo está relacionado con la elección de Silvano (en el 305 o en el 307/308), quien llegó a hacerse elegir obispo de Cirta (actual Constantine)gracias a la ayuda del arenarius Muto. Esta ayuda quedó bien demostrada por el testimonio de diversas personas durante el proceso seguido contra Silvano en el 320, en el que se reconoció su culpabilidad y se le condenó al exilio. El segundo ejemplo es el del papa Dámaso (366), elegido obispo de Roma en la iglesia de Lucina el mismo día en el que el diácono Ursino era escogido en la basílica de Julio. En el conflicto siguiente, Dámaso convocó a arenarii, quadrigari y fossores, quienes acudieron en su ayuda fuertemente armados. Éstos atacaron la basílica en la que se habían refugiado los partidarios de Ursino y el resultado del asalto fue de 137 muertos. [eng]The habit of engaging fighters of the amphitheatre (arenarii) as a personal guard in the factional struggles survived during the 4th century. Although in most cases it was about political causes, we know two examples where the candidates to be bishops turned to gladiators in order to overcome their opponents. The first example is that of election of Silvanus (305 or 307-308), who got the bishopric of Cirta (the modern Constantine) thanks to the help of the arenarius Mutus. This help was proved by the testimony of several witnesses during the trial which was followed against Silvanus in 320, where his guilt was admitted and he was condemned to the exile. The second exemple is that of the the Pope Damasus (366), elected bishop of Rome in the church of Lucina in the same day as the deacon Ursinus was elected in the basilica of Julius. In the conflict that was to follow, Damasus called arenarii, quadrigarii and fossores who came to help him heavily armed. They attacked the basilica where the supporters of Ursinus had taken refuge and as a result of the assault 137 people died.

The impact of "early" nineteenth-century globalization on foreign trade in the Southern Cone: A study of British trade statistics

This paper deals with the impact of "early" nineteenth-century globalization (c.1815-1860) on foreign trade in the Southern Cone (SC). Most of the evidence is drawn from bilateral trades between Britain and the SC, at a time when Britain was the main commercial partner of the new republics. The main conclusion drawn is that early globalization had a positive impact on foreign trade in the SC, and this was due to: improvements in the SC's terms of trade during this period; the SC's per capita consumption of textiles (the main manufacture traded on world markets at that time) increased substantially during this period, at a time when clothing was one of the main items of SC household budgets; British merchants brought with them capital, shipping, insurance, and also facilitated the formation of vast global networks, which further promoted the SC's exports to a wider range of outlets.

Roman amphora trade across the Straits of Gibraltar: An ancient 'anti-economic practice'?

Summary. Olive oil and fish products from the south of Hispania and North Africa played an important role in the Roman economy. The authors call attention to the asymmetrical distribution of archaeological data available on this subject, in particular the location of amphora kilns, and try to give an explanation, based on the evolution of European archaeology in the twentieth century.

Indicadors de pressió ambiental a les platges de Menorca: prova pilot (IPAPM'pp)

L’augment del turisme experimentat des de principis dels anys 70 a l’illa de Menorca (Illes Balears, Espanya) ha provocat un impacte sobre les seves platges, el seu principal atractiu turístic. Molts d’aquests impactes s’incrementen durant la temporada alta, compresa entre els mesos de maig a octubre. L’objectiu principal d’aquest projecte és l’elaboració d’un sistema d’indicadors de pressió ambiental útils per a l’anàlisi de les platges. La zona objecte d’estudi de la prova-pilot, correspon a les platges del sud-oest de Menorca, aquestes cales són les que actualment es troben sotmeses a una major pressió. Es tracta de catorze platges tipificades en tres categories (A, B, C) segons les característiques del tipus d’espai on es troben situades. Són les platges de: Cala Degollador, Cala Blanca, Cala’n Bosch, Son Xoriguer, Son Saura-Es Banyul, Son Saura-Bellavista, Es Talaier, Cala Turqueta, Cala Macarelleta, Cala Macarella, Cala Galdana, Cala Mitjana, Cala Trebalúger i Cala Escorxada. Partint d’un treball bibliogràfic, s’ha realitzat una selecció de mig centenar d’indicadors potencials dels quals catorze han format part dels IPAPM’pp, mitjançant l’elaboració d’una anàlisi multicriteri. Per a cada un dels IPAPM’pp s’ha desenvolupat una metodologia amb les corresponents fitxes individuals descriptives per al seu seguiment temporal. En aquest primer estudi, l’indicador que presenta un nombre de valors no acceptables en una major proporció de platges, és l’indicador 3. Índex de valoració de les mesures de conservació del sistema natural, seguit de l’indicador 6. Superfície subsistema sorra per usuari. El 2006, les platges de tipologia A, presenten un major percentatge positiu de les variables dels indicadors. Les platges de tipologia B i C presenten un percentatge menor d’acceptabilitat dels valors dels indicadors.

Link between microstructure and properties in new metallurgical concepts for very low loss non-oriented electrical steel

The influence of chemistry and soaking temperature (maximal temperature of the continuous annealing) on the final properties of non-oriented electrical steels has been studied. With this objective two different studies have been performed. First the Mn, Ni and Cr content of a low loss electrical steel composition has been modified. An intermediate content and a high content of each element has been added in order to study the influence of this components on the magnetic looses, grain size and texture. Secondly the influence of the soaking temperature on magnetic properties, grain size and oxidation in four grades of non-oriented electrical steels (Steel A, B, C and D) was studied.

Prevalence and persistence of gymnodimines in clams from the Gulf of Gabes (Tunisia) studied by mouse bioassay and LC-MS/MS

In this work we studied the toxicity in clams from the Gulf of Gabes, Tunisia (Southern Mediterranean). Samples from two stations (M2 and S6) were collected monthly from January 2009 to September 2010, and analyzed by the official control method of mousse bioassay (MBA) for lipophilic toxins. All samples were also analyzed with the LC-MS/MS method for the determination of lipophilic toxins, namely: okadaic acid group, pectenotoxins, yessotoxins and azaspiracids, spirolides and gymnodimines (GYMs). The results showed prevalence of GYMs since it was the only toxin group identified in these samples with a maximum of 2,136 μg GYM -A kg-1 (February 2009 at M2). Furthermore, GYMs showed persistence in the area, with only one blank sample below the limit of detection. Interestingly, this blank sample was found in June 2009 after an important toxic episode which supports the recent findings regarding the high detoxification capability of clams, much faster than that reported for oysters. In comparison, good agreement was found among MBA, the LD50 value of 80-100 μg kg-1 reported for GYM- A, and quantitative results provided by LC-MS/MS. On the contrary to that previously reported for Tunisian clams, we unambiguously identified and quantified by LC-MS/MS the isomers GYM- B/C in most samples. Phytoplankton identification and enumeration of Karenia selliformis usually showed higher densities at site M2 than S6 as expected bearing in mind toxin results, although additional results would be required to improve the correlation between K. selliformis densities and quantitative results of toxins. The prevalence and persistence of GYMs in this area at high levels strongly encourages the evaluation of the chronic toxic effects of GYMs. This is especially important taking into account that relatively large quantities of GYMs can be released into the market due to the replacement of the official control method from mouse bioassay to the LC-MS/MS for lipophilic toxins (Regulation (EU) No 15/2011), and the lack of Regulation for this group of toxins.

AMADEUS: advanced manipulation for deep underwater sampling

AMADEUS is a dexterous subsea robot hand incorporating force and slip contact sensing, using fluid filled tentacles for fingers. Hydraulic pressure variations in each of three flexible tubes (bellows) in each finger create a bending moment, and consequent motion or increase in contact force during grasping. Such fingers have inherent passive compliance, no moving parts, and are naturally depth pressure-compensated, making them ideal for reliable use in the deep ocean. In addition to the mechanical design, development of the hand has also considered closed loop finger position and force control, coordinated finger motion for grasping, force and slip sensor development/signal processing, and reactive world modeling/planning for supervisory `blind grasping¿. Initially, the application focus is for marine science tasks, but broader roles in offshore oil and gas, salvage, and military use are foreseen. Phase I of the project is complete, with the construction of a first prototype. Phase I1 is now underway, to deploy the hand from an underwater robot arm, and carry out wet trials with users.

New York versus la tragedia y Edipo. El legado sofocleo -y sofístico- en Crimes and Misdemeanors de W. Allen

Más allá de la referencia explícita a la tragedia griega y Edipo, el objetivo de este artículo es presentar la estrecha relación, en opinión del autor, entre lo que mantienen los protagonistas en Crimes and Misdemeanors y las teorías de los sofistas griegos sobre Dios, la ley, etc. Una confrontación minuciosa de sus textos con el guión de la película revela claramente unas raíces sofísticas que no pueden ser atribuidas, en este caso, a la presencia constante del legado judío en la obra de W. Allen.
