Stable isotope evidence for 1500 years of human diet at the city of York, UK

We present here the results of a large-scale diachronic palaeodietary (carbon and nitrogen isotopic measurements of bone collagen) study of humans and animals from a single site, the city of York (U.K.) dating from the Roman period to the early 19th century The human sample comprises 313 burials from the cemeteries of Trentholme Drive and Blossom Street (Roman), Belle Vue House (Anglo-Saxon), Fishergate (High and Later Medieval), and All Saints, Pavement (Later and Post-Medieval). In addition, 145 samples of mammal, fish and bird bone from the sites of Tanner Row and Fishergate were analyzed. The isotope data suggest dietary variation between all archaeological periods, although the most significant change was the introduction of significant quantities of marine foods in the Medieval periods. These are first evident in the diet of a small group of individuals from the High Medieval cemetery at Fishergate, although they were consumed almost universally in the following periods. The human isotope values are also remarkable due to unusually elevated delta N-15 ratios that are not sufficiently explained by the comparably small enrichment in C-13 that accompanies them. We discuss the possible reasons behind this and the archaeological significance of the data set.

Formation and circulation of the cold intermediate layer in the Gulf of Saint Lawrence

[ 1] The local heat content and formation rate of the cold intermediate layer (CIL) in the Gulf of Saint Lawrence are examined using a combination of new in situ wintertime observations and a three-dimensional numerical model. The field observations consist of five moorings located throughout the gulf over the period of November 2002 to June 2003. The observations demonstrate a substantially deeper surface mixed layer in the central and northeast gulf than in regions downstream of the buoyant surface outflow from the Saint Lawrence Estuary. The mixed-layer depth in the estuary remains shallow (< 60 m) throughout winter, with the arrival of a layer of near-freezing waters between 40 and 100 m depth in April. An eddy-permitting ice-ocean model with realistic forcing is used to hindcast the period of observation. The model simulates well the seasonal evolution of mixed-layer depth and CIL heat content. Although the greatest heat losses occur in the northeast, the most significant change in CIL heat content over winter occurs in the Anticosti Trough. The observed renewal of CIL in the estuary in spring is captured by the model. The simulation highlights the role of the northwest gulf, and in particular, the separation of the Gaspe Current, in controlling the exchange of CIL between the estuary and the gulf. In order to isolate the effects of inflow through the Strait of Belle Isle on the CIL heat content, we examine a sensitivity experiment in which the strait is closed. This simulation shows that the inflow has a less important effect on the CIL than was suggested by previous studies.

Richard le Scandinave? Héroïsme et métissage culturel dans le Roman de Rou de Wace

This article explores the bilingual and bicultural identity of Normandy revealed by Wace's depiction of Duke Richard the Fearless in the Roman de Rou. The anecdotes that open the Troisieme Partie of the Rou are analysed in the light of Scandinavian analogues, in particular the Saga of Grettir. This allows us to discern in Wace's stories a dual tradition, with romance and scandinavian strands that were not always mutually compatible, resulting in narrative tensions that had hitherto remained unexplained. In particular, the fearless duke takes on connotations of mental instability that would only have been recognised by the Normans of Danish origin.

La fontaine bouillonnante et la tombe de Lancelot l'Ancien: modalités textuelles et iconographiques de la construction cyclique dans le Lancelot-Graal

La tête du roi Lancelot l'Ancien, l'aïeul du chevalier Lancelot, assassiné par le duc de Belle Garde, est plongée dans une fontaine merveilleuse bouillonnante, tandis que son corps, gardé par deux lions, est conservé dans un tombeau extraordinaire dont suintent des gouttes de sang aux propriétés curatives. Sur le plan textuel, les références aux merveilles qui suivent la mort de Lancelot l'Ancien dans l'Estoire del saint Graal, le Lancelot et la Queste del Saint Graal témoignent de la construction du cycle du Lancelot-Graal par l'intégration d'une dimension à la fois historique et généalogique. Or l'iconographie des manuscrits enluminés du cycle du Graal privilégie davantage la mise en série d'épisodes apparentés que la construction d'une logique véritablement cyclique. Le remploi de compositions ou de motifs iconographiques renforce la cohérence de l'univers chevaleresque et merveilleux ainsi créé sans pour autant impliquer d'effet de circularité.

Trypanosoma evansi: Adenosine deaminase activity in the brain of infected rats

The study was undertaken to evaluate changes in the activity of adenosine deaminase (ADA) in brains of rats infected by Trypanosoma evansi. Each rat was intraperitoneally infected with 10(6) trypomastigotes either suspended in fresh (group A; n = 13) and cryopreserved blood (group B; n = 13). Thirteen animals were used as control (group C). ADA activity was estimated in the cerebellum, cerebral cortex, striatum and hippocampus. No differences (P > 0.05) in ADA activity were observed in the cerebellum between infected and non-infected animals. Significant (P < 0.05) reductions in ADA activity occurred in cerebral cortex in acutely (day 4 post-infection; PI) and chronically (day 20 PI) infected rats. ADA activity was significantly (P < 0.05) decreased in the hippocampus in acutely infected rats, but significantly (P < 0.05) increased in the chronically infected rats. Significant (P < 0.05) reductions in ADA activity occurred in the striatum of chronically infected rats. Parasites could be found in peripheral blood and brain tissue through microscopic examination and PCR assay, respectively, in acutely and chronically infected rats. The reduction of ADA activity in the brain was associated with high levels of parasitemia and anemia in acute infections. Alterations in ADA activity of the brain in T. evansi-infected rats may have implications for pathogenesis of the disease. (C) 2010 Elsevier Inc. All rights reserved.

New exotic charmonium states

In the last years many states in the charmonium mass region were discovery by BABAR, Belle and CDF collaborations I discuss some of these discoveries, and how the QCD Sum Rule approach can be used to understand the structure of these states

Can the X(4350) narrow structure be a 1(-+) exotic state?

Using the QCD sum rules we test if the new narrow structure, the X(4350) recently observed by the Belle Collaboration, can be described as a J(PC) = 1(-+) exotic D(s)(*)D(s0)(*) molecular state. We consider the contributions of condensates up to dimension eight, we work at leading order in alpha(s) and we keep terms which are linear in the strange quark mass Ins. The mass obtained for such state is m(Ds*Ds0*) = (5.05 +/- 0.19) GeV. We also consider a molecular 1(-+), D(s)(*)D(s0)(*); current and we obtain m(D*D0*) = (4.92 +/- 0.08) GeV. We conclude that it is not possible to describe the X(4350) structure as a 1(-+) D(s)(*)D(s0)(*) molecular state. (C) 2010 Elsevier B.V. All rights reserved.

Théâtre du Grand-Guignol : Les mécanismes de la peur dans deux pièces du théâtre médical d’André de Lorde et Alfred BinetL’Obsession et Une leçon à la Salpêtrière .

Le Grand-Guignol n’a reçu que peu d’attention critique sérieuse jusqu’à la fin des années 1980. Ce petit théâtre a pendant 65 ans, de 1897 à 1962, offert des pièces d’un genre nouveau mêlant terreur, violence et souvent érotisme. Le succès était au rendez-vous et le Théâtre du Grand-Guignol est longtemps resté une attraction incontournable de Paris. Les pièces choisies pour ce mémoire sont issues de ce répertoire et ont cela de particulier qu’elles ont été écrites en collaboration entre un écrivain, André de Lorde, et un psychologue, Alfred Binet. Malgré leurs différences, ces pièces ont une constante, un point commun : elles suscitent toutes la peur chez le spectateur. C’est précisément la façon dont Binet et de Lorde établissent cette peur à travers leurs pièces qui sera l’objet d’étude de ce mémoire. Ce mémoire se limite à l’analyse de deux œuvres en particulier : L’Obsession, et Une leçon à la Salpêtrière. Appréhender la notion de peur dans une œuvre théâtrale impose de réfléchir non seulement aux thèmes développés mais également à la construction dramatique du récit et à sa mise en scène. Dans le cas spécifique d’une pièce Grand-Guignol, il y aura une dimension supplémentaire à inclure : ce que l’on peut appeler « l’expérience Grand-Guignol ». De quelles façons le fait même d’aller voir une pièce dans ce théâtre participait-il à l’anticipation et au sentiment de peur nécessaire à l’efficacité des pièces ?  Après un bref rappel de l’histoire du Grand-Guignol, les causes externes comme le quartier de Montmartre, mais aussi les habiles coups publicitaires des premiers directeurs artistiques ainsi que la configuration du théâtre lui-même sont étudiées pour montrer comment elles ont largement contribué à créer un véritable mythe autour du Grand-Guignol. Dans la deuxième partie, une analyse spécifique des deux pièces mentionnées précédemment est faite. Les questions suivantes ont été posées : sur quels thèmes pouvaient bien jouer les auteurs pour toucher leur public ? En quoi ces thèmes reflétaient-ils les peurs de l’époque, c’est-à-dire de la « Belle Epoque » ? Dans la dernière partie, une analyse textuelle et scénique a été faite au cours de laquelle il a été tenté de comprendre comment les auteurs provoquent et entretiennent la peur et l’angoisse à travers à la fois la construction dramatique des pièces et leurs jeux de scène.

Crescimento econômico secular no Brasil, modelo de thirlwall e termos de troca

Explaining the Brazilian economic growth performance during the 20th is a challenging task to academics. As shown, Brazil had already experienced faster growth and recently it is far from such belle époque. Most explanation lies on conventional frameworks. This paper assesses the Thirlwall’s balance-of-payments constraint model to Brazilian economic growth in the period 1900-2005, highlighting the importance of the terms of trade. The results show, first, that the terms of trade are significant in the estimation of import demand function and change the income elasticity, especially in the first period of the sample (1900-1970), and, second, when the simplest Thirlwall’s model is controlled by terms of trade, it seems that such variable is important through export growth, which cause changes in economic performance.

Parc Royal: um magazine na modernidade carioca

Este estudo versa sobre o Parc Royal, uma loja de departamentos que existiu no Rio de Janeiro entre 1873 e 1943. A pesquisa foi delimitada por um recorte temporal que abrange o período da belle époque (1898-1914) e os anos 1920, um período onde ocorreu um complexo processo de transformações nas esferas da moda, do comércio, da comunicação, das sociabilidades, em pleno curso da modernidade urbana. Vislumbramos o objeto da presente dissertação como pretexto que permite entrever questões mais amplas, tais como a adoção de padrões estrangeiros de civilidade, a disseminação da cultura das aparências e do consumo de bens icônicos, a evolução da indumentária e do arquétipo feminino. Como opção metodológica, contemplamos a análise das representações construídas na publicidade do magazine, em anúncios publicados em diversos periódicos da época. Sob o comando do imigrante português José Vasco Ramalho Ortigão, a atuação do Parc Royal é analisada como um veículo para o entendimento da lógica de funcionamento de parte da sociedade do Rio de Janeiro no início do Século XX, desvelando a adoção de valores, usos e costumes que expressavam os interesses de um determinado grupo social.
