It is commonly supposed that in the eighth century B.c. there was a ‘population explosion’ in Greece which moved the Greeks to send out colonies. A. J. Graham in the Cambridge Ancient History iii, 3 (1982) is typical: ‘The basic active cause of the colonizing movement was overpopulation’; ‘at the very time when the Archaic colonising movement began, in the second half of the eighth century, there was a marked increase in population in Greece’ (p. 157). The presumed connection between overpopulation and colonisation is not immediately obvious. The evidence for the population explosion is found in the increased number of burials in Attica and the Argolid, but Athens sent out no colony before the very end of the seventh century and Argos probably none at all, certainly none in this period. So special explanations have to be formulated for Athens' and Argos' lack of colonies while their postulated ‘population explosion’ is presumed for Greece as a whole and called in to explain the burst of colonising in the eighth century. The hypothesis is not used for seventh-century colonisation when the number of burials declines.

AbstractBorings in the Argive Plain reveal cycles of marine incursions, each ending with a Mediterranean soil profile and followed by a prograded fluvial and coastal wedge. The sediment prism of the Gulf of Argos shelf, visible in high-resolution seismic reflection profiles, also consists of transgressive and regressive depositional sequences identified by onlap, downlap, and truncation of deposits. At least four major reflectors, recognizable by their high acoustic impedance and erosional features, can be correlated across the shelf. The sediments between each pair of reflectors represent the seaward part of a set of transgressive and regressive marine deposits. They can be matched to the stratigraphic sequence on land where each marine unit is topped by a soil. Corrected for subsidence, the terminations of the onlapping and downlapping units define a local sea-level history; its time scale can be derived from a comparison with the eustatic sea-level history deduced from ocean cores. Thus, marine seismic reflection data can be used for the correlation of Quaternary oceanic and terrestrial chronologies.

Full textAbstract:
The plain of Argos, southern Greece, is perhaps the first region in Greece where sea water intrusion in groundwater was noticeably observed since late fifties. Observed chloride concentrations, are mostly less than 1500 mg/l, in the affected zone, exhibiting smooth variations. Also, relevant water quality data, show that sharp fronts are not occurring. Thus, the transport of chlorides is assumed to be governed by advection and dispersion mechanisms rather than density dependent transport. In this paper the application of a distributed numerical model, based on advective and dispersive - chloride transport is described. Hence, the mathematical model of a "homogeneous fluid" and the "tracer" approach has been assumed rather that the "general" approach of the "heterogeneous fluid". This code has successfully replicated the measured concentrations of the calibration period (1964-69) and also the pertinent concentrations of the validation period (1969-750). In predictive simulation, a scenario of chloride flushing by natural recharge, without any pumping, was tested and it was calculated that rehabilitation period could be at least as long as twenty years. The weakness of this model involves both errors of conceptual model and numerical errors. The major conceptual problem is the lack of knowledge of pumping distribution, which constitutes the driving force of salinization, while numerical errors are mainly attributed to mass balance errors introduced in the Eulerian - Lagrangian implementation of the numerical model.

The following work refers to an experimental methodology employed for in situ monitoring of specific soil water fluxes constituting water balance components. The test area is located in the plain of Argos - Greece, within an orange grove. A micrometeorological station was installed in the site, equipped with several sensors for real time monitoring of various atmospheric parameters as well as water content and temperature in the soil profile. The soil profile was made accessible for sampling through a rectangular pit which was excavated close to the station. The soil water content was monitored making use ofTDR sensors which were calibrated against the traditional neutron probe technique and also by soil sampling. Tensiometeres were also installed in four different depths for monitoring the matrix potential. A software programme was developed for the analysis and the evaluation of the data collected in a 10 - minute time step. The analysis of the data showed that the three - year average of Actual Evapotranspiration, in this irrigated field, was approximately 857 mm, out of which almost 600mm occur between April and September and 260 mm in the winter period. Those results show that there is no significant water surplus for deep infiltration and aquifer recharge in clayey and clay - loam soils in this region.

Full textAbstract:
The object of this study is the analysis of the sanctuary with a double cella or double temple (ἱερὸν διπλοῦν) dedicated to Aphrodite and Ares in the periurban area north-west of Argos. Within the context of studies on Greek architecture, a specific analysis of the typology of cult structures with a double cella is still lacking, since the attestations have hitherto been considered too limited. The present study, still ongoing, has uncovered a complex situation and the archaeological attestations recovered are not as limited as thought in the past. Hitherto, around twenty examples have been collected, without considering uncertain cases, for which the limited data available have rendered a precise interpretation impossible. The only direct source on the Argive sanctuary of Aphrodite and Ares is the short description provided by Pausanias (2.25.1), whilst its location, ground plan, elevation, chronology and architectural and sculptural decoration remain essentially unknown. New observations may help clarify some of the issues that remain unresolved. The closest archaeological parallel, at least from the point of view of the ground plan, in the absence of information on the dimensions of the monument, is without doubt the temple of Venus and Roma in Rome, built by the emperor Hadrian (AD 117-138), with which the Argive temple also shares the same east-facing orientation of the cella dedicated to the goddess Aphrodite-Venus.

Full textAbstract:
Aeschylos’ tragedy The Suppliantsis in this article related to an opposition between clan and state—and more specifically with the development in ancient Greece from barbarism to civilization, from a lawless, uncultivated and disorganised world, to a clan-based social order and from there to a state-based organisation, which in many ways would set the pattern for the development in Europe for centuries to come.In the play, fifty sisters are fleeing from Egypt to Argos, persecuted by their fifty male cousins. The women seek protection and therefore refer to their shared origins with the population of Argos.The fact that Danaus has fifty daughters but no son, implies that if the daughters marry their cousins the legacy will stay within the clan. What the daughters’ uncle Aegyptus and his sons demand is that Danaus and his daughters should act in accordance with the regulatory framework of the clan system. This stipulates that in cases where fathers in patrilineal systems only have daughters, these daughters must marry endogamically (that is inwards) instead of exogamic ally (outwardly, and in the corresponding way for sons in matrilineal systems).The article shows how Argos, governed by King Pelasgus, is depicted in the play in contrast to the claustrophobic catatonia of incestuous relations, the latter illustrated by an imagery that stems from archaic Greek mythology. The claustrophobic feeling that links the family and kin in The Suppliants, through events such as incestuous marriages and family-related cannibalism, gives a picture of the individual’s room for manoeuvre being strictly regulated—in fact almost non-existent—in the extended family. It is such a claustrophobic world that the women in The Suppliants (like Orestes in Oresteia) are fleeing from.Instead they seek out a city state based on fundamentally different ideas than the family, kinship and clan-related organisation principles of the Egyptians. The Greek city state thereby appears to aim to liberate the archaic human from a claustrophobic captivity.

Full textAbstract:
Orestes as a resistance fighter, or the myth of the Atreides in Theo Angelopoulos’s film The travelling playersThe paper examines the use of the Atreides myth in Theo Angelopoulos’s film The travelling players (1975) in the context of the director’s interpretation of the phenomenon of myth. Angelopoulos treated myth as a set of archetypical situations and patterns of conduct constantly reproduced in the history of the world. He intertwined elements of classical stories with the history of Greece and the Byzantine tradition, thus showing their universal character. In The travelling players, Angelopoulos used the story of betrayed and murdered Agamemnon, who is avenged by his children: Orestes and Electra, but he moved it into modern times, setting the film in Greece of the 1940s and 1950s. The myth is reproduced with modulations: the most important events take place as a result of interventions of History, not fate or decisions of the gods. Moreover, the characters’ conflicts are enriched with a political dimension, as Angelopolous portrays the discord between their ideological stances. But the members of the acting company are as helpless in the face of events as the family of the king of Argos. Orestes bojownikiem ruchu oporu, czyli mit Atrydów w filmie Podróż komediantów Theo AngelopoulosaArtykuł jest analizą sposobu wykorzystania przez Theo Angelopoulosa mitu Atrydów w filmie Podróż komediantów (1975) w kontekście dokonanej przez niego interpretacji zjawiska mitu. Grecki reżyser traktował mit jako zbiór archetypicznych sytuacji i wzorów postępowania odtwarzanych nieustannie w dziejach świata. Elementy antycznych opowieści splatał w filmach z historią Grecji i tradycją bizantyjską, ujawniając ich uniwersalny charakter. W Podróży komediantów wykorzystał historię zdradzonego i zamordowanego Agamemnona, który zostaje pomszczony przez swoje dzieci: Orestesa i Elektrę, ale przeniósł ją w czasy współczesne, portretując Grecję lat 40. i 50. XX wieku. Mit zostaje zreprodukowany z modulacjami: kluczowe wydarzenia następują w wyniku interwencji historii, nie fatum czy decyzji bogów. Ponadto konflikty między postaciami zostają wzbogacone o wymiar polityczny, ponieważ Angelopoulos ukazuje rozdźwięk między ich postawami ideologicznymi. Jednak członkowie trupy aktorskiej pozostają wobec wydarzeń tak samo bezradni jak rodzina władcy Argolidy.

The Family of Zeus in Early Greek Poetry and Myths
In early epic poetry it is evident that certain differences exist in both traditions, mainly due to the fact that Homer’s epic poems were written on the western coast of Asia Minor and the surrounding islands, while Hesiod’s poems were composed on mainland Greece. From the analysis, it becomes clear that the development of the cult of an Indo-European Sky Father differs significantly from the assumed Proto-Indo-European tradition. His family is completely different from that in the Indo-European tradition. His wife is the goddess Hera, whom Homer calls ‘old’, as opposed to the Hesiodic tradition, in which Hestia and Demeter are older than her. Homer makes no mention whatsoever of Hestia. The ‘daughters of Zeus’ are the goddesses Athena and Aphrodite, and the ‘son of Zeus’ is Apollo. The family of Zeus according to Homer also differs from the archaeological findings of the tradition on land. Hera of Samos bears no resemblance to Hera of Argos. The oldest large temples are connected to her, as well as to the memory of Oceanus and Thetis as parents to the gods, which is a direct influence of the Mesopotamian myths of Apsu and Tiamat. Homer’s Zeus from Mount Ida, Hera of Samos, Apollo of Cilla, and Tenedus and Artemis of Ephesus are closer to the Anatolian tradition.

Full textAbstract:
Argos est l’un des sites majeurs de la Grèce dont l’occupation n’a cessé depuis le Néolithique jusqu’à nos jours. Cette occupation continue se traduit par un patrimoine anthropologique riche, en partie exhumé par les fouilles de l’École Française d’Athènes. Depuis les premières fouilles de Wilhelm Vollgraff en 1902, Argos a livré plusieurs centaines de tombes dispersées dans la ville moderne. Nous adoptons ici une approche bio-archéologique des sépultures, de l’Helladique moyen à l’époque ottomane, ayant livré des restes anthropologiques, en vue d’apporter un éclairage nouveau sur ce qui pouvaient être les conditions de vie à Argos. Un travail d’identification est tout d’abord réalisé afin de rendre exploitable cette collection, en grande partie issue de fouilles anciennes. Pour les 341 individus dénombrés, on a procédé à une estimation du sexe et de l’âge à travers l’étude anthropologique. Une étude croisée est ensuite réalisée faisant appel à des disciplines variées telles que : l’anthropologie dentaire, l’étude des isotopes stables ou encore la tribologie. Cela nous fournit une carte d’identité unique des individus de cette collection. Notre synthèse illustre l’intérêt de ce type d’approche multidisciplinaire en revisitant notre perception de l’Helladique moyen (2000-1600 BC), La confrontation des données bio-archéologiques et des pratiques funéraires permet de confirmer, ou parfois de nuancer, nos connaissances sur la Grèce mésohelladique parfois qualifiée de “tiers monde” de l’Égée. On y entrevoit un monde certes difficile, mais dans lequel la position d’Argos semble finalement relativement confortable en comparaison des sites voisinsArgos is one of the major sites of Greece whose occupation has continued since the Neolithic to the present. This continued occupation results in a rich anthropological heritage, partly revealed by the excavations of the French School of Athens. Since the first excavations conducted by Wilhelm Vollgraff in 1902, Argos has revealed hundreds of graves scattered in the modern city. We adopt here a bio-archaeological approach of the burials from the Middle Helladic to the Ottoman period, which delivered anthropological remains, with the intention to shed new light on what could have been the living conditions in Argos. An identification work is first performed to make usable this collection, which largely results from earlier excavations. For the 341 individuals listed, sex, age and stature could be determined through anthropological study. A crossover study was then carried out using a variety of disciplines such as dental anthropology, the study of stable isotopes or tribology. This provides us with a unique description of the individuals of this collection. Our synthesis illustrates the value of this type of multidisciplinary approach by revisiting our perception of the Middle Helladic period (2000-1600 BC). Comparison of bio-archaeological and burial practices data confirms or sometimes nuances, our knowledge of mesohelladic Greece sometimes called the “third world” of the Aegean. It envisions a world that is certainly difficult, but in which Argos finally seems to be in a relatively comfortable position compared to neighboring sites

Full textAbstract:
Cette thèse s’inscrit dans une démarche de géographie historique et d’histoire des représentations de l’espace dans l’Antiquité. Elle vise avant tout à essayer de combler une lacune de l’historiographie contemporaine, à savoir celle d’une définition spatiale de ce que recouvre le terme d’Argolide et des réalités auxquelles il renvoie aux époques archaïque et classique. Cette région, située au nord-est du Péloponnèse, n’apparaît proprement sous le nom d'Argolide, dans les textes littéraires, qu’à l’époque romaine. Une unité territoriale préexistait-elle aux périodes plus anciennes ? L’Argolide est-elle un territoire ou une région aux époques archaïque et classique ou n’est-elle qu’une construction historiographique des Anciens et des Modernes ? En partant de l’analyse des territorialités qui se sont exprimées à ces époques dans la péninsule argolique, nous nous interrogeons sur les représentations spatiales qui touchaient cet espace, pour comprendre s’il formait alors chez les Anciens une unité géographique. La péninsule argolique est parcourue de nombreuses identités, qui forment autant de territoires à des échelles variées (celles de la kômè, de la cité ou encore du territoire ethnique), sans pour autant avoir une identité propre et affirmée qui ferait d’elle un territoire. L’Argolide est le résultat d’une intervention active d’Argos dans le domaine des représentations : elle correspond non seulement au lot de Téménos, qui constitua le mythe argien territorial par excellence, mais aussi à l’association des domaines sur lesquels règnent Agamemnon et Diomède dans le Catalogue des Vaisseaux. L’Argolide regroupe donc symboliquement l’ensemble du nord-est du Péloponnèse. Entité mythologique dans l’imaginaire argien qui se diffusa dans l’ensemble de la Grèce archaïque et classique, l’Argolide est également une réalité tangible, puisqu’elle forme une véritable région aux époques archaïque et classique, c'est-à-dire un cadre propice aux interactions économiques, cultuelles ou culturellesThis thesis follows the methodology of historical geography and of the history of spatial representations in Ancient Greece. Its main goal is to fill the gap in contemporary historiography, regarding the spatial definition covered by the term of Argolid and the realities to which it refers in the archaic and classical periods. The Argolid, located in the north-east of the Peloponnese, only appears as a region in literature during the Roman period. Did a territorial unit exist in earlier periods? Is the Argolid a territory or a region in the archaic and classical periods or is it just a histographical construct by the Ancients and Moderns?Starting from the analysis of expressed territorialities at these times in the Argolic peninsula, we study the spatial representations related to this space, in order to understand whether it formed a geographical unit for the Greeks back then. In the Argolic peninsula, many identities coexisted, which formed as many territories at different scales (those of kome, of the city or of the ethnic territory). Nevertheless, the peninsula did not have a clear and strong identity that would have made it a territory.The Argolid is the result of active interventions of Argos in the field of representations: it is linked not only to the lot of Temenos, which constituted the famous territorial Argive myth, but also to the association of the areas under the rule of Agamemnon and Diomedes in the Catalogue of Ships. The Argolid hence symbolically includes all the cities of the northeastern Peloponnese. Originally a mythological entity in Argives’ minds, which was later diffused throughout the archaic and classical Greece, the Argolid is also a concrete reality, since it forms a real region in Archaic and Classical periods, that is to say, a favorable environment to economic, worship or cultural interactions

L'objet de cette thèse est l'étude du terrain cultuel argien et de la toile des relations tissées entre les Argiens et leurs dieux par le biais des pratiques religieuses. Celles-ci sont envisagées dans un cadre chronologique large, de l'organisation de la cité d'Argos au VIlle s. av. notre ère, à la visite de Pausanias à Argos au Ile s. de notre ère. À l'aide de toutes les sources disponibles, nous étudions les espaces sacrés et le temps religieux argiens à de multiples échelles : de l'"oikos" aux sanctuaires de la cité, des rites quotidiens aux cultes rendus lors des grandes fêtes annuelles, de l'acte individuel à l'action collective de groupes - professionnels ou associatifs - ou de l'ensemble de la cité. Ce faisant, nous avons cherché à replacer sans cesse les hommes au centre de ces questions afin d'appréhender aussi bien les relations qu'ils entretenaient avec leurs divinités que le rôle de chacun des acteurs, des responsables des charges religieuses aux participants anonymesThe main purpose of this thesis is to clarify the Argive cultic ground and the web of relationships woven between the Argives and their Gods, thanks to numerous religious practices performed from the Eighth century BC, date of the organization of the polis, till the Second century AD, when Pausanias visited this city. Studying the ancient sources at our disposition, I propose an account of the Argive sacred spaces and time, following a range of multiple scales : from the oikoi to the city sanctuaries, from the rites of the everyday life to those performed during annual and civic festivals, from the individual pious acts to those implicating a restricted group - cultic or professional associations - or the city as a whole. Proceeding step by step, I always tried to put men and women at the centre of all these questions in order to show not only the relationship they established with their gods but also their roles as actors - anonymous individuals or those taking hold or sharing a religious charge - playing a part in cultic practices

In this work, using the Green-Kubo method combined with Molecular Dynamic (DM), we calculate the thermal conductivity of a solid Argon "free of defects"and with point defect present, for temperatures varying from 10 up to 60 K at density 22,3 ml/mol. The obtained results are in good agreement with the available theoretical and experimental results in the limites of low and high temperatures, but with some discrepances in about 15 % for intermediate values of temperatures. The purpose to include point defects with the objective of correction of the simulational results to compare with experimental measuremments for intermediate temperatues had not the expected e?ect. However, we believe that it should be due to the fact that the density used in the simulation for the point defect is high based on the experimental estimates of point defect density in this system. Our results suggest that the Green-Kubo method combined with Molecular Dynamics is a powerful tool to calculate the thermal conductivity of solids at high temperatures. With the construction of accurate and reliable interatomic potentials to describe more complex materials, such as high temperature ceramic and minerals at extreme condiction of pressure and temperature, this method could soon become very useful to calculate thermal conductivity in materials where the access to experimental data is hard.
Neste trabalho, usando o método de Green-Kubo combinado com a Dinâmica Molecular (DM), calculamos a condutividade têrmica do Argônio sólido livre de defeitos ;e com defeitos pontuais presentes, para um intervalo de temperatura variando de 10 a 60 K e uma densidade de 22,3 ml/mol. Os resultados obtidos estão em pleno acordo com os resultados teóricos e experimentais disponíveis nos limites de baixa e alta temperatura, mas com alguma discrepância em torno de 15 % para valores intermediários de temperatura. A proposta para incluir defeitos pontuais com o objetivo de correção dos resultados da simulação para comparar com as medidas experimentais para temperaturas intermediárias não surtiu o efeito esperado, no entanto, acreditamos que isto se deve ao fato da densidade de defeitos ser alta baseado em estimativas da densidade de defeitos neste sistema. Nossos resultados sugerem que o método de Green-Kubo combinado com DM é uma ferramenta poderosa para se calcular a condutividade térmica de sólidos a altas temperaturas. Com a construção de potenciais interatômicos mais precisos e con fiáveis para descrever materiais mais complexos, como é o caso de cerâmicas a altas temperaturas e minerais em condições extrema de pressão e temperatura, esse método poderá em breve ser muito útil para calcular a condutividade térmica em materiais onde o acesso a dados experimentais é mais difícil.

Full textAbstract:
The Prospect Rock Fault (PRF) is key to our understanding of the regional tectonic evolution of Vermont during the Taconic, Salinic, and Acadian Orogenies, and may have played an important role in the exhumation of blueschist and eclogite-facies rocks in the Tillotson Peak Complex (TPC) during the Taconic Orogeny. The TPC is in the footwall of the PRF in the eastern limb of the Green Mountain Anticlinorium. In the TPC, the dominant foliation is S2 and E-W trending F2 folds parallel L2 stretching lineations, which trend orthogonal to regional N-S trending folds associated with the Taconic Orogeny. The PRF itself is folded by F2 folds. Presently, there is a lack of consensus about the role of the PRF in the exhumation of the TPC, and studies have not reconciled the formation of the E-W folds and lineations to a regional model.
Oriented samples and structural data were collected from the footwall of the PRF over several transects. Samples were processed into orthogonal thin sections for microstructural analyses and for 40Ar/39Ar step heating of white mica. The dominant foliations in the PRF samples were identified through microstructural analysis and correlating the age of deformation as S2 and S3. These were defined in thin section by mica and quartz microlithons, and oriented mica grains. S1, and in some samples S2, are locally preserved in some mica domains and albite/garnet inclusion trails. S4 appears as crenulations of S3, with no significant new mineral crystallization. In the field, L2 and L3 lineations are defined by mineral and quartz rods, and L4 lineations are defined as intersection lineations on S2 surfaces.
40Ar/39Ar analyses yielded plateau ages ranging from 458.6 ± 2.0 Ma to 419.0 ± 2.4 Ma (1σ). The oldest plateau ages are just slightly younger, yet concordant, with published and new 40Ar/39Ar ages from the TPC and come from the structurally highest portions of the footwall in the northern part of the study area. Virtually all apparent age spectra show age gradients. Results from this study suggest the PRF played a role in exhumation of the TPC and ages obtained are closely aligned with deformation ages constrained from 40Ar/39Ar dating in southern Quebec for the Taconic D2 and Salinian D3 deformation.

Full textAbstract:
L’ensemble d'histoires autour du bosom serpent se réfère à des croyances et des récits diffus qui attribuent, de manière interculturelle, le mal-être physique à l’intrusion présumée d'animaux qui entrent et vivent dans le corps du souffrant. Les recherches se sont concentrées jusqu’alors sur le folklore bosom serpent moderne et contemporain : les témoignages prémodernes ont été, de fait, largement ignorés. En me concentrant, dans cette étude, sur une vaste gamme de sources prémodernes, dont les exemples proviennent en grande partie d’Eurasie, et en adoptant une perspective comparée à la fois folklorique, historique, médicale et ethnologique, mon objectif sera de mettre en lumière ce thème d’un point de vue diachronique. Je remonterai dans le temps en suivant les occurrences des bosom serpents et j’examinerai les ramification et les adaptations variées des ethiologies traditionnelles qui les concernent. Dans leur ensemble, ces disciplines (folklore, histoire, médecine et ethnologie) offrent une apporche crédible, promeuvent la recherche collaborative et permettent l’utilisation d’une méthode scientifique basée sur une multiplicité de sources. Je montrerai qu’une grande quantité de ressemblances interculturlles, jusqu'alors considérées étrangères ou même inexplicables, font en réalité partie d'un même ensemble narratif. Ces ressemblances sont les adaptations de l’idée polymorphe, mais prédominante, centrée sur l'impossible intrusion d’animaux dans le corps humain. Les bosom serpents prémodernes, solidement ancrés dans les notions médicales et religieuses de tous les jours, furent formellement acceptés comme des faits concrets et tangibles, pouvant être appréhendés par la médecine, la démonologie et la sorcellerie. Leur charge émotive était puissante, parfois latente, et ils figurèrent probablement depuis toujours dans les traditions narratives humaines et dans les expériences personnelles. Dans ce contexte, une attention particulière sera donnée aux thèmes expérientiels et aux délires chrnoniques d’hommes et de femmes qui croient avoir été pénétrés par des animaux fantastiques. De la même manière que les bosom serpents entendus comme agents et causes de maladie, ces patients souffrant de zoopathie interne peuvent être retracé sur une longue période temporelle, jusqu’aux origines de la psychopathologieThe bosom serpent story-complex refers to widespread cross-cultural narratives and beliefs attributing physical discomfort to alleged animals entering and living in the body of the sufferer. Scholarly enquiries have concentrated on modern and contemporary bosom serpent folklore: pre-modern evidence has been largely neglected. Focusing, in this dissertation, on a vast range of pre-modern sources – examples can be found from much of Eurasia –, and adopting a folklore, a historical, a medical and an ethnological comparative perspective, my aim will be to throw more light on the theme from a diachronic point of view. I will, in fact, follow evidence for bosom serpents back through time and examine the ramifications and various adaptations of traditional aetiologies involving them. Taken together these disciplines (folklore, history, medicine and ethnology) offer a credible approach, encourage collaborative research and allow a multi-source method. I will show that a great deal of cross-cultural similarities, hitherto considered unrelated or unexplained, belong to the same story-complex. They are adaptations of the polymorphic and predominant idea of the impossible intrusion of animals into a human body. Pre-modern bosom serpents, firmly grounded in everyday medical and religious notions, were formerly accepted as concrete and tangible facts to be understood in terms of medicine, demonology, and sorcery. They had a powerful or latent emotional charge and have perhaps always figured in story-telling traditions and personal experience narratives. In this context, particular attention will be devoted to experiential themes and the chronic delusions of men and women who believed themselves to have been involuntarily penetrated by fantastic animals. Like bosom serpents cast as causative agents of disease, these suffers from internal zoopathy can be traced back in time at the beginnings of psychopathology
Il complesso di storie sul bosom serpent si riferisce a diffusi racconti e credenze che attribuiscono, cross-culturalmente, il disagio fisico a presunti animali intrusivi che entrano e vivono nel corpo del sofferente. Le indagini degli studiosi si sono concentrate sul folklore bosom serpent moderno e contemporaneo: l’evidenza pre-moderna è stata largamente ignorata. Concentrandomi, in questa dissertazione, su una vasta gamma di fonti pre-moderne – esempi possono essere rintracciati in gran parte dell’Eurasia –, e adottando una prospettiva comparata folklorica, storica, medica e etnologica, il mio obiettivo sarà quello di gettare più luce sul tema da un punto di vista diacronico. Seguirò, infatti, le evidenze di bosom serpents indietro nel tempo ed esaminerò le ramificazioni e i vari adattamenti delle eziologie tradizionali che li riguardano. Nel loro insieme queste discipline (folklore, storia, medicina ed etnologia) offrono un approccio credibile, promuovono la ricerca collaborativa e permettono l’utilizzo di un metodo scientifico basato su molteplici fonti. Mostrerò che una grande quantità di somiglianze cross-culturali, fino a questo momento considerate estranee o addirittura inspiegabili, appartengono allo stesso complesso narrativo. Esse sono adattamenti dell’idea polimorfica, ma predominante, incentrata sull’impossibile intrusione di animali nel corpo umano. I bosom serpents pre-moderni, saldamente radicati nella nozioni mediche e religiose di tutti i giorni, furono formalmente accettati come fatti concreti e tangibili intesi in termini di medicina, demonologia e stregoneria. Essi ebbero una carica emotiva potente, talvolta latente, e probabilmente figurarono da sempre nelle tradizioni umane del narrare e nelle esperienze personali. In questo contesto, un’attenzione particolare verrà dedicata ai temi esperienziali ed ai deliri cronici di uomini e donne che credettero di essere stati penetrati da animali fantastici. Esattamente come i bosom serpents intesi come agenti causa di malattia, questi pazienti sofferenti di zoopatia interna possono essere rintracciati molto indietro nel tempo nei primordi della psicopatologia

Systematic studies of basal nonsense suppression, orthogonality of tRNAPyl variants, and cross recognition between codons and tRNA anticodons are reported. E. coli displays detectable basal amber and opal suppression but shows a negligible ochre suppression. Although detectable, basal amber suppression is fully inhibited when a pyrrolysyl-tRNA synthetase (PylRS)-tRNAPyl_CUA pair is genetically encoded. trnaPyl_CUA is aminoacylated by an E. coli aminoacyl-tRNA synthetase at a low level, however, this misaminoacylation is fully inhibited when both PylRS and its substrate are present. Besides that it is fully orthogonal in E. coli and can be coupled with PylRS to genetically incorporate a NAA at an ochre codon, tRNAPyl_UUA is not able to recognize an UAG codon to induce amber suppression. This observation is in direct conflict with the wobble base pair hypothesis and enables using an evolved M. jannaschii tyrosyl-tRNA synthetase-tRNAPyl_UUA pair and the wild type or evolved PylRS-tRNAPyl_UUA pair to genetically incorporate two different NAAs at amber and ochre codons. tRNAPyl_UCA is charged by E. coli tryptophanyl-tRNA synthetase, thus not orthogonal in E. coli. Mutagenic studies of trnaPyl_UCA led to the discovery of its G73U form which shows a higher orthogonality. Mutating trnaPyl_CUA to trnaPyl_UCCU not only leads to the loss of the relative orthogonality of tRNAPyl in E. coli but also abolishes its aminoacylation by PylRS.

Full textAbstract:
Argos, situated in the southern peninsula of Greece called the Peloponnese, lies on the northwest side of the Argos Plain, backed by hills to the north and west that are the eastern edge of an extensive region of mountains and intermountain basins. A road runs northward through the valley and over the hills to Nemea and Corinth. Eastward beyond the capricious rivers lie the old Mycenaean cities of Mycenae and Tiryns on their knolls, with the port of Nauplia closing the circuit to the southeast. Beyond Nauplia is the Argolid peninsula with the ancient pilgrimage and health center of Epidauros. (The term “Argolid” as used in the literature sometimes means all the area near Argos and sometimes means only the peninsula south and east of Nauplia. Herein, we will use Argolid for the latter and Argive Plain for the former.) Between Argos and the gulf about 6 km south is the marshy area of Lerna, remnant of a lake that once reached nearly to the outskirts of Argos, while the southeast part of the plain was until recently a series of lagoons (Piérart 1992). To the southwest, skirting the mountains, runs the road to Sparta. The advantages for Argos of being situated at the center of gravity in the triangular plain (Runnels 1995) continued throughout all the periods studied herein. Argos is unusual among ancient cities because we have ample modern geological investigations of regional structure, morphology, karst geology, and hydrogeology, literary evidence from antiquity, and archaeological data from decades of investigation. These materials contribute to a detailed understanding of how human settlement built on and responded to local resources. We will therefore describe the regional setting of the city before turning to an examination of the urban core. Below its mountains, the city of Argos stands on a shelf overlooking a plain of extensive fertile agricultural land that curves around the site from north to southwest. The stratigraphy is as follows, beginning with the topmost modern layers: . . . Higher plateau and mountains are Tripoli limestone. Tripoli plateau sits amid karstic mountains. (Older) Triassic and Jurassic limestones to the northeast. . . .

The evidence of archaeological surveys and excavations, official documents, architecture, and art history are considered across the regions and cities of the Peloponnese and central to northern Greece in social and economic contexts. The nature of the production and export of wine, oil, and silk throughout Greece as cash-generating products of the countryside is also examined. Particular attention is paid to ceramics both as markers for interpreting the archaeological evidence and as possible indicators of otherwise undocumented population movements. The conclusions are that the cities of the Peloponnese—Corinth, Sparta, and Argos—acquired a new prosperity during the eleventh century but not to the extent of Athens and Thebes. Thebes in particular became a desirable place to live and outstripped all the other cities of Greece in its affluence by the twelfth century. The successful development of Thebes is associated with a recently identified major pottery production site at its port of Chalkis/Euripos. Finally it is suggested that the population increase throughout Greece in the eleventh century which made intensification of land use possible came about through mass movements of people from Asia Minor.

Full textAbstract:
The Mycenaean cemetery of Deiras has enjoyed relatively little attention by Aegean scholars. This is mainly due to the rather modest character of its contents, which does not favor quantitative analysis of “wealth” and “status” differences among individuals. Based on the assumption that mortuary patterns “mirror” social structure, such approaches have been extensively used to analyze social complexity and “explain” state-formation processes in Mycenaean Greece. Recent theoretical discussions, however, have demonstrated the limitations of such reflexive approaches. Funerals are now seen as dynamic fields of social performance and negotiation, which may skew rather than “reveal” intergroup relations. To understand their importance, one needs to examine them within their specific context, i.e., in dialogue with what preexisted, not what followed. In this chapter, we apply such an approach on the Mycenaean cemetery of Deiras. First we examine the gradual development of the cemetery in the context of Argos and how it related to other burial grounds and the settlement of the site. Then we attempt a comparative examination with other Mycenaean cemeteries of the Argolid. It is suggested that LH IIB/IIIA1 was the period of most intense deposition of valuables in Argolic graves, and the stage during which a number of typically “Mycenaean” practices and symbolisms were standardized. This raises the question whether one should look at this period, rather than the much more diverse LH I–IIA, for the rise of a common code of funerary behavior, which used exclusive ritual performances in the entrances of the tombs and the disposal of material acquisitions as basic indices of social identity. This may have had wider repercussions: the distribution of valuables in LH IIB/IIIA1 suggests that it was during this period when Mycenae acquired a special role as a major re-distributive centre in the Argolid.

Full textAbstract:
A city is the locus of both sociocultural and physical-technical elements in a society. To begin to understand the importance of both kinds of factors, ancient cities are convenient examples to study, especially dead ones that do not “wiggle” under the microscope. By isolating one urban system (water management) we can begin to understand the complication and variability that characterize these early cities, and hence gain insight into the development of other urban systems, as well as the role that water management plays in the evolution of all cities. The received wisdom about the placement of cities usually rates defense as the primary factor, with access to arable land and concentration of trade activities being the other two important factors. A hill top, a protruding ridge, a peninsula or an isthmus between two rivers—all were sites easily defended by walls and hand weapons. Even a broad plain could be utilized if there were a slight rise that could be fortified, such as at the Mycenaean city of Tiryns in Greece. A city on a slight rise in the midst of broad fields of arable and irrigable soil was ideal. Such a formulation leaves out the possibility of deliberately choosing as a site a port city that tapped directly into grazing lands, or the importance of a balance of either fish or meat complementing cereals in the diet. It is more accurate to say that two kinds of food were necessary, either crops and fish or crops and meat. This concept broadens the number and kinds of “ideal” sites. Trade routes, the third factor, also are more complex in form and have more varied effects on urban location than early theories would admit. There are at least three kinds: 1. Overland routes (e.g., the Santa Fe Trail, with its two terminals at Independence, Mo., and Santa Fe., N.M., with Santa Fe being a crossroads where routes from Los Angeles and Mexico City also converged) 2. Land and water interchanges (the north-south land route through France crossing at Paris the east-west river route along the Seine) 3. Water-water interchanges such as New Orleans (Gulf of Mexico and Mississippi River) or Amsterdam (Rhine River and Atlantic Ocean)

A seismic analysis has been performed showing that the seismic interaction between the UIS and the FHM can be avoided eliminating the internal clearance of bearing at the FHM arm joint. An angular contact ball bearing is suitable for the new FHM since it can eliminate gaps by preload pressure. A major problem of the FHM bearings is lubrication since the contact pressure between the steel rings and ball of the ball bearing is larger than that of the roller bearing used in the previous design. Additionally, FHM operating temperature is about 200deg-C and normal grease is not applicable under argon gas with sodium vapor to prevent contamination of grease in the primary sodium coolant. An endurance test with 1/10 scale bearings in the air has been performed to show applicability of angular contact ball bearings to the FHM arm joint. The results with 20,000cycle showed that bearings with combination of MoS2 coating steel rings and ceramics balls can be tolerable as the FHM operating condition. A full-scale bearing test in argon gas with sodium vapor has also been demonstrated to reveal bearing size and sodium vapor effects.

Full textAbstract:
The objective of this paper is to determine the thermal conductivity of Zinc Oxide nanowire by Steady State Non-equilibrium and Transient Non-equilibrium Molecular Dynamics (SS-NEMD and T-NEMD) simulations using the ReaxFF reactive force field [5]. While SS-NEMD uses an equilibrated system and statistical averaging; T-NEMD uses cooling/heating rates in order to calculate the conductivity. The validity of the methods is first verified using Argon as a test case. The thermal conductivity of Argon thus calculated is compared with those presented by Bhowmick and Shenoy [20]. We then study the effects of system size using SS-NEMD method while effects of periodic boundary conditions — 1D, 2D and bulk variation of conductivity with temperature are analyzed using T-NEMD simulations. The results obtained compare favorably with those measured experimentally [12, 13]. Thus the SS-NEMD and T-NEMD methods are alternatives to the traditional Green-Kubo approach. In conjunction with ReaxFF, they are computationally cheaper than the Green-Kubo method and can be used to determine the thermal conductivity of materials involved in surface chemistry reactions such as catalysis and sintering.

Full textAbstract:
Nanofluids have been proposed as a route for surpassing the performance of currently available heat transfer liquids for better thermal management needed in many diverse industries and research laboratories. Recent experiments on nanofluids have indicated a significant increase in thermal conductivity with 0.5 to 2% of nanoparticle loading in comparison to that of the base fluid. But the extent of thermal conductivity enhancement sometimes greatly exceeds the predictions of well established classical theories like Maxwell and Hamilton Crosser theory. In addition to that, these classical theories can not explain the temperature and nanoparticle size dependency of nanofluid thermal conductivity. Atomistic simulation like molecular dynamics simulation can be a very helpful tool to model the enhanced nanoscale thermal conduction and predict thermal conductivities in different situations. In this study a model nanofluid system of copper nanoparticles in argon base fluid is successfully modeled by equilibrium molecular dynamics simulation in NVT ensemble and thermal conductivities of base fluid and nanofluids are computed using Green Kubo method. The interatomic interactions between solid copper nanoparticles, base liquid argon atoms and between solid copper and liquid argon are modeled by Lennard Jones potential with appropriate parameters. For different volume fractions of nanoparticle loading, the thermal conductivities are calculated. The nanoparticle size effects on thermal conductivities of nanofluids are also systematically studied. This study indicates the usefulness of MD simulation to calculate thermal conductivity of nanofluid and explore the higher thermal conduction in molecular level.

Full textAbstract:
The bulk thermal conductivity of Lennard-Jones argon and Stillinger-Weber silicon is predicted using the Green-Kubo (GK) and direct methods in classical molecular dynamics simulations. While system-size independent thermal conductivities can be obtained with less than 1000 atoms for both materials using the GK method, the linear extrapolation procedure [Schelling et al. Phys. Rev. B 65, 144306 (2002)] must be applied to direct method results for multiple system sizes. It is found that applying the linear extrapolation procedure in a manner consistent with previous researchers can lead to an underprediction of the GK thermal conductivity (e.g., by a factor of 2.5 for Stillinger-Weber silicon at a temperature of 500 K). To understand this discrepancy, phonon properties are predicted from lattice dynamics calculations, and from these, length-dependent thermal conductivities. These results show that the linear extrapolation procedure is only accurate when the minimum system size used in the direct method simulations is comparable to the largest mean free paths of the phonons that dominate the thermal transport. This condition has not typically been satisfied in previous works.

Abstract Nanofluids have become the subject of theoretical and experimental researches over the few decades due to their enhanced heat transfer performance. In this study, thermal conductivity of copper argon nanofluids is determined through MD simulation. Different types of nanoparticles based on shape was used to make nanofluids. Role of different shape of nanoparticles such as cylindrical, cubical and spherical was disused. Green Kubo method is employed to determine the thermal conductivity of the nanofluids. Result shows that, for volume fraction 3% and 86 K system temperature, thermal conductivity enhancement of nanofluid containing spherical, cubical and cylindrical shape is 15%, 40% and 50% respectively compared with that of base fluid. Thermal conductivity enhancement of nanofluid for spherical particle at 86 K, 94 K and 102 K is 15%, 30% and 40% respectively while for volume fraction 3%, 6% and 9%, the enhancement is 15%, 35% and 45% respectively. The mechanism of increased heat transfer performance for different shape of the nanoparticles is discussed in this paper.

Full textAbstract:
Using molecular dynamics simulations, an analysis of the thermal conductivity enhancement of a copper/argon nanofluid is performed. First, verification of an increase of as much as ∼30% in the thermal conductivity of the theoretical nanofluid over the corresponding base fluid, due to increasing nanoparticle concentration, is presented. Thermal energy transport is then decomposed into potential, kinetic, and virial components, based on the Green-Kubo autocorrelation function used to calculate thermal conductivity from the microscopic properties of the system. Analysis of these components showed that as the concentration of the nanoparticle increases, the energy transported through the system, due to collisions within the fluid, decreases by as much as 80%. Additionally, the nanofluid system increasingly displays characteristics of an amorphous-like material with increasing concentration. The decrease in energy exchange, due to collisions, suggests another physical mechanism is present for thermal energy transport. Therefore, it is proposed that thermal diffusion is the physical mechanism that more significantly affects thermal energy transport within a nanofluid than had been previously suggested.

Full textAbstract:
The Green-Kubo method in the framework of equilibrium molecular dynamics (EMD) simulations is an effective method that has been widely used to calculate thermal conductivities of materials. The previous studies focused on the thermal conductivity values or the average values from repetitive simulations. Little research has been done to investigate the uncertainties of the thermal conductivities from EMD simulations. In this paper, we use solid argon as the material system to study the factors influencing the uncertainties of the predicted thermal conductivities. We find that the uncertainties decrease with the total simulation time as (ttotal)−α and increase with correlation time as (tcorre)β, where 0.48 < α, β < 0.52. We also find that the uncertainties decrease with increasing temperature, but the simulation domain size has a negligible effect. We propose some guidelines for selecting appropriate simulation parameters (e.g., the correlation time and total simulation time) to achieve a desired level of uncertainty. This work is potentially useful for future studies on calculating the thermal conductivities of materials using EMD simulations.
