The Uses of Print and Writing in Eighteenth Century European Ballet: the Case of The Letters on Dancing and Ballets by Jean-Georges Noverre

This article aims to study the uses of print, especially the Letters on Dancing and Ballets by Jean-Georges Noverre, throughout the emergence of pantomime ballet in the late eighteenth century. Noverre’s discourse is directly associated with a project to revitalize the art of dance. In this sense, books as an object are not only a support for the new aesthetic discourse, but a tool with multiple uses. It simultaneously seeks to modify the spectator’s view of the scene, legitimize the success of the new theatrical genre and value the ballet master profession.

L’écriture de Mohammed Dib entre photographie et intertexte

En 1946, Muni de son Rolleiflex, Dib, tout jeune photographie sa ville natale Tlemcen. En 1994, il publie son livre Tlemcen ou les lieux d’écriture, un texte empreint de nostalgie et d’amour pour sa ville et pour son pays. Ses photos y côtoient ses textes anciens dans un biblio personnel. Le lecteur se trouve entre un présent et un passé appelé sémiologiquement de deux procédés différents, mais complémentaires ; l’image et le texte. Dans cet article, nous nous proposons d’étudier comment la photographie s’est installée dans l’œuvre de Dib et comment elle se trouve au centre de son intérêt littéraire et nostalgique à la fois. Puis, nous verrons comment l’intertexte, devenu autotexte, est un moyen de vivre la nostalgie.   

La pintura que no se deja ver. La pintura avergonzada, la pintura escondida (a propósito de los escritos de Ángela de La Cruz, Georges didi-Huberman y Honoré de Balzac)

El artículo «La pintura que no se deja ver: la pintura avergonzada, la pintura escondida» relaciona una de las primeras obras de la artista Ángela de la Cruz ashamed (1995), con La pintura encarnada (1984) de Georges Didi-Huberman, ensayo que a su vez analiza La obra maestra desconocida (1837) de Honoré de Balzac. Entre Ángela de la Cruz, didi-Huberman y Balzac se establece un triángulo en torno al concepto cuadro-cuerpo. A través de una pintura, un ensayo filosófico y un relato, tres autores de tres tiempos distintos recuperan las mismas ideas de carne y piel pictórica y cuadro humanizado. Su objetivo: superar las barreras de representación en la pintura para crear un ser más allá del objeto pictórico. Sin embargo, cuanto más idealizan la pintura y más pretenden superar la pantallapictórica, más se desvanece el concepto de «cuadro»; cuanto más acercan el cuadro a ser, más se aleja de ser un cuadro y menos se permite el acceso a lo que representa. La persecución del ideal implica que el cuadro se vea sometido a su ocultación, al deterioro y a la destrucción de su imagen.

Georges Lemaître: a visionary contribute to the quest of the world model

The aim of this dissertation is to present the sequence of events which brought the scientific community of the early 20th century to conceive an expanding Universe born from a single origin. Among the facts here reported, some are well-known, some others instead are little-known backstories, not so easy neither to obtain nor to trust. Indeed, several matters shown in this thesis, now as then, create a battleground among scientists. Amid the numerous personalities whose contributions are discussed in this work, the main protagonist is surely Georges Lemaître, who managed to combine – without overlapping – his being both a priest and a scientist. The first chapter is dedicated to his biography, from his childhood in Belgium, to his early adulthood between England and the USA, to his success in the scientific community. The second and the third chapter explain how the race to the understanding of a Universe which not only expands, but also originated from a singularity, developed. The Belgian priest’s discoveries, as shown, were challenged by other important scientists, who, in several cases, Lemaître had a friendly relationship with. As a consequence, the fourth and final chapter deals with the multiple relations that the priest managed to build, thanks to his politeness and kindness. Moreover, it is also covered Lemaître’s personal connection with the Church and religion, without forgetting the personalities that influenced him – above all, Saint Thomas Aquinas. As a conclusion to this thesis, two appendices gather not only a summary of Lemaître’s works which are not already described in the chapters, but also the biographies of all the characters presented in this dissertation.

Produção de biotensoativos a partir de resíduos de óleos e gorduras

O presente trabalho visou a seleção de microrganismos com capacidade de produzir biotensoativos a partir de resíduos de óleos e gorduras gerados em restaurantes e indústrias alimentícias. Borra de soja, gordura de frango, gordura vegetal hidrogenada e óleo de soja usado em frituras foram estudados como fonte de carbono. Os isolados LMI 6c e LMI 7a, ambos pertencentes ao gênero Pseudomonas, foram selecionados como potenciais produtores de biotensoativos. Dentre os resíduos propostos, a borra de soja foi considerada o melhor substrato, gerando 9,69 g.L-1 de ramnolipídios e uma tensão superficial de 31 mN/m.

Trabalho e imigração: uma comparação Brasil-Argentina

O artigo busca discutir um novo padrão migratório da Bolívia para o Brasil e para a Argentina, especialmente vinculado à precarização do trabalho e à inserção desses imigrantes em formas de trabalho precário. Esse padrão & aparentemente novo em relação à integração dos contingentes migrantes ao longo do século XX & vem produzindo consequências que ainda estão por ser mapeadas. Uma delas é a presença de um contingente de bolivianos confinado ao setor de costura, trabalhando e vivendo em oficinas clandestinas, com pouca visibilidade pública, como face de uma precarização mundializada, resultante do assim chamado “custo chinês”. Resultante de um balanço bibliográfico e de uma incursão exploratória na pesquisa de campo tanto em São Paulo como em Buenos Aires, o artigo pretende apontar para aspectos específicos do fenômeno, combinando olhares e perspectivas que cruzam as dimensões migratórias, geracionais e de gênero.

Elevated Risk for HIV-1 Infection in Adolescents and Young Adults in São Paulo, Brazil

Background. Recent studies have sought to describe HIV infection and transmission characteristics around the world. Identification of early HIV-1 infection is essential to proper surveillance and description of regional transmission trends. In this study we compare people recently infected (RI) with HIV-1, as defined by Serologic Testing Algorithm for Recent HIV Seroconversion (STARHS), to those with chronic infection. Methodology/Principal Findings Subjects were identified from 2002-2004 at four testing sites in São Paulo. Of 485 HIV-1-positive subjects, 57 (12%) were defined as RI. Of the participants, 165 (34.0%) were aware of their serostatus at the time of HIV-1 testing. This proportion was statistically larger (p<0.001) among the individuals without recent infection (n = 158, 95.8%) compared to 7 individuals (4.2%) with recently acquired HIV-1 infection. In the univariate analysis, RI was more frequent in <25 and >59 years-old age strata (p<0.001). The majority of study participants were male (78.4%), 25 to 45 years-old (65.8%), white (63.2%), single (61.7%), with family income of four or more times the minimum wage (41.0%), but with an equally distributed educational level. Of those individuals infected with HIV-1, the predominant route of infection was sexual contact (89.4%), with both hetero (47.5%) and homosexual (34.5%) exposure. Regarding sexual activity in these individuals, 43.9% reported possible HIV-1 exposure through a seropositive partner, and 49.4% reported multiple partners, with 47% having 2 to 10 partners and 37.4% 11 or more; 53.4% of infected individuals reported condom use sometimes; 34.2% reported non-injecting, recreational drug use and 23.6% were reactive for syphilis by VDRL. Subjects younger than 25 years of age were most vulnerable according to the multivariate analysis. ) Conclusions/Significance In this study, we evaluated RI individuals and discovered that HIV-1 has been spreading among younger individuals in São Paulo and preventive approaches should, therefore, target this age stratum

Nonlinear diffraction of light beams propagating in photorefractive media with embedded reflecting wire

The theory of nonlinear diffraction of intensive light beams propagating through photorefractive media is developed. Diffraction occurs on a reflecting wire embedded in the nonlinear medium at a relatively small angle with respect to the direction of the beam propagation. It is shown that this process is analogous to the generation of waves by a flow of a superfluid past an obstacle. The ""equation of state"" of such a superfluid is determined by the nonlinear properties of the medium. On the basis of this hydrodynamic analogy, the notion of the ""Mach number"" is introduced where the transverse component of the wave vector plays the role of the fluid velocity. It is found that the Mach cone separates two regions of the diffraction pattern: inside the Mach cone oblique dark solitons are generated and outside the Mach cone the region of ""optical ship waves"" (the wave pattern formed by a two-dimensional packet of linear waves) is situated. Analytical theory of the ""optical ship waves"" is developed and two-dimensional dark soliton solutions of the generalized two-dimensional nonlinear Schrodinger equation describing the light beam propagation are found. Stability of dark solitons with respect to their decay into vortices is studied and it is shown that they are stable for large enough values of the Mach number.
