Synchrotron Radiation-Based Micro-XANES and Micro-XRF Study of Unsuccessfully Produced Egyptian Blue from the Late Hellenistic Production Site of Kos…
2021
International audience; This paper examines the production technology of Egyptian blue, an ancient artificial pigment, through the investigation of an unsuccessfully produced pellet derived from the Hellenistic production site of Kos (Dodecanese, Greece). This heterogeneous material was investigated by a combination of laboratory and synchrotron radiation-based (SR) techniques: scanning electron microscopy coupled with energy-dispersive Xray spectrometry, micro-Raman spectroscopy, high-resolution SR micro-X-ray fluorescence spectroscopy, and SR micro-X-ray absorption near-edge structure spectroscopy (XANES), at the ID21 beamline of the European Synchrotron Radiation Facility. Principal comp…
Induction of DNA strand breaks and expression of HSP70 and GRP78 homolog by cadmium in the marine sponge Suberites domuncula
1998
The marine sponge Suberites domuncula was used as a bioindicator to study the effects of cadmium on the occurrence of DNA strand breakage and on the induction of the expression of the stress biomarkers, heat shock protein 70 (HSP70) and glucose-regulated protein 78 (GRP78) homolog. The cDNA encoding GRP78 homolog from S. domuncula was isolated and characterized. The GRP78 cDNA has a length of 2.1 kb and displays characteristic features of the HSP70 family ; it encodes an aa sequence of M-r 72, 000. Exposure of S. domuncula to 1 mg/L of cadmium chloride for 24 h caused a strong(16.6-fold) increase in cadmium content to 7.7 mu g/g wet weight of sponge tissue ; after an incubation period of 6 …
The CO2 output from the Sperchios Basin area (central Greece): the role of hidden degassing from streams
2018
The Sperchios Basin is an actively spreading rift area with deeply rooted extensional faults and also a site of quaternary volcanic activity. Such geologic conditions favoured the formation of many hydrothermal systems, whose surface expressions are among the biggest thermal springs of the whole Greece. Degassing of deeply derived geogenic CO2 is highlighted by strong bubbling within the main pools of the springs. Flux measurements were made in the Thermopyles spring with the floating chamber method and results showed that bubbling gases in the spring release about 1 ton/day of CO2. The outgoing stream has a flow of more than 250 l/s of water rich in CO2 (about 16 mmol/l). Although no bubbl…
La economía social y solidaria en Grecia
2017
El 31 de octubre de 2016 el Parlamento griego aprobó la Ley 4430/2016 de Economía Social y Solidaria (ESS) con el propósito de difundir esta forma alternativa de organización de la actividad económica; apoyar y fortalecer proyectos productivos autogestionarios y de emprendimiento social colectivo, y regular las Empresas Sociales Cooperativas y las Cooperativas de Trabajadores. En este trabajo hemos analizado las principales características de la ESS griega, principalmente en relación con otros modelos europeos; y los distintos tipos de empresas que integra, subrayando las diferencias entre ellas y sus principales características frente a otras instituciones próximas como las cooperativas so…
Is naturalistic driving research possible with highly instrumented cars? Lessons learnt in three research centres.
2011
This paper provides an overview of the experiences using Highly Instrumented Cars (HICs) in three research Centres across Europe; Spain, the UK and Greece. The data collection capability of each car is described and an overview presented relating to the relationship between the level of instrumentation and the research possible. A discussion then follows which considers the advantages and disadvantages of using HICs for ND research. This includes the obtrusive nature of the data collection equipment, the cost of equipping the vehicles with sophisticated Data Acquisition Systems (DAS) and the challenges for data storage and analysis particularly with respect to video data. It is concluded th…
Geochemical characterisation of the thermo-mineral waters of Greece
2021
AbstractGeothermal areas of Greece are located in regions affected by recent volcanism and in continental basins characterised by elevated heat flow. Many of them are found along the coast, and thus, water is often saline due to marine intrusion. In the current study, we present about 300 unpublished and literature data from thermal and cold mineral waters collected along Greece. Samples were analysed for major ions, Li, SiO2 and isotopes in water. Measured temperatures range from 6.5 to 98 °C, pH from 1.96 to 11.98, while Total Dissolved Solutes (TDS) from 0.22 to 51 g/L. Waters were subdivided into four main groups: (1) thermal; (2) cold; (3) acidic (pH < 5); and (4) hyperalkaline (pH …
Travestirsi per Dioniso
2020
Starting from the definition of “performativity” and “gender parody” developed by Judith Butler, this paper aims to investigate the performative functions of male cross-dressing within the dynamics of social categorization in classical Athens. For this purpose I have adopted an eclectic hermeneutic toolbox, borrowing elements from Harvey Sacks’ Membership Categorization Analysis to René Girard’s scapegoat theory. Through the philological analysis of some literary representations of transvestism, such as Pentheus’ cross-dressing in Euripides’ "Bacchae", and the anthropological interpretation of the mythical-ritual complex relating to the effeminacy of Dionysus, my work focuses on the polyval…
Phillip II of Macedon: The First European. Asia and Europe as Political Concepts in Classical Greece
2021
El presente artículo tiene como objetivo analizar la evolución histórica y cultural de Europa y Asia como términos políticos en la Grecia clásica. Para ello, abordaremos fuentes de diversa índole como Esquilo, Heródoto, el escrito hipocrático Aires, aguas y lugares y el orador Isócrates. Partiremos de la equiparación inicial entre Europa (= Grecia) y Asia (= Persia) hasta alcanzar la propuesta de Isócrates de considerar a Filipo como un líder europeo. The aim of this paper is to analyse the historical and cultural evolution of Europe and Asia considered as a political terms in Classical Greece. In order to achieve this objective, we will address several primary sources such as Aeschylus’ Pe…
The diverse genetic origins of a Classical period Greek army.
2022
Trade and colonization caused an unprecedented increase in Mediterranean human mobility in the first millennium BCE. Often seen as a dividing force, warfare is in fact another catalyst of culture contact. We provide insight into the demographic dynamics of ancient warfare by reporting genome-wide data from fifth-century soldiers who fought for the army of the Greek Sicilian colony of Himera, along with representatives of the civilian population, nearby indigenous settlements, and 96 present-day individuals from Italy and Greece. Unlike the rest of the sample, many soldiers had ancestral origins in northern Europe, the Steppe, and the Caucasus. Integrating genetic, archaeological, isotopic, …
Polymorphisms in ABC transporter genes and concentrations of mercury in newborns - Evidence from two Mediterranean birth cohorts
2014
Background: The genetic background may influence methylmercury (MeHg) metabolism and neurotoxicity. ATP binding cassette (ABC) transporters actively transport various xenobiotics across biological membranes. Objective: To investigate the role of ABC polymorphisms as modifiers of prenatal exposure to MeHg. Methods: The study population consisted of participants (n = 1651) in two birth cohorts, one in Italy and Greece (PHIME) and the other in Spain (INMA). Women were recruited during pregnancy in Italy and Spain, and during the perinatal period in Greece. Total mercury concentrations were measured in cord blood samples by atomic absorption spectrometry. Maternal fish intake during pregnancy w…
