La estela de Orfeo: poética de la trascendencia en Juan Eduardo Cirlot

El presente trabajo explora la figura de Orfeo y la corriente del orfismo con la finalidad de establecer una nueva interpretación del mito a nivel psicológico, histórico y filosófico. El resultado pretende servir de base para el estudio de la poesía en poetas contemporáneos que aluden a dicho mito, que lo reescriben para crear su propia versión o bien que lo utilizan de herramienta para elaborar su poética personal. En este caso se toma como ejemplo la obra del poeta español Juan Eduardo Cirlot, que es analizada desde el punto de vista de lo que se ha concluido en llamar “órfico”.

La práctica médico-quirúrgica en la primera generación del movimiento "novator" a través de las obras de Juan Bautista Juanini (Milán, 1632 - Madrid, 1691): imagen historiográfica, saberes médicos y prácticas quirúrgicas

El objetivo principal de este trabajo es realizar un nuevo acercamiento a la figura histórica, la obra y, en concreto, la práctica médico-quirúrgica de un autor hispanoitaliano de finales del siglo XVII. Nos referimos concretamente al cirujano cortesano Juan Bautista Juanini (Milán, 1632 – Madrid, 1691). Como objetivo secundario se trataría de intentar realizar una nueva presentación biográfica del autor dentro de una recapitulación más general del papel que representó en el contexto de la revolución científica y médica de los países del sur de Europa, y en concreto entre los miembros de la primera generación de "novatores" hispánicos.

El largo viaje de Juan Preciado: propuesta de lectura de la novela Pedro Páramo desde la mitología nahua

Nuestro trabajo pretende abrir una nueva línea de análisis de la novela de Juan Rulfo Pedro Páramo que explore el arquetipo de la muerte que se esconde en el recorrido que realiza el protagonista de la novela, Juan Preciado, por el fantasmal pueblo de Comala, a través del mito nahua que narra el viaje del alma desencarnada al inframundo, al Mictlán

Tragedia contemporánea y su posibilidad: Himmelweg de Juan Mayorga

Utilizando como ejemplo la obra Himmelweg, de Juan Mayorga, se pretende demostrar la existencia de la tragedia en el drama contemporáneo, estableciendo, primero, la posibilidad de un sentimiento trágico actual y, segundo, las bases de la dramaturgia contemporánea tras la crisis del drama expuesta por Peter Szondi.

The Early Cretaceous San Juan Plutonic Suite, Ecuador: A magma chamber in an oceanic plateau ?

Sections through an oceanic plateau are preserved in tectonic slices in the Western Cordillera of Ecuador (South America). The San Juan section is a sequence of mafic-ultramafic cumulates. To establish that these plutonic rocks formed in an oceanic plateau setting, we have developed criteria that discriminate intrusions of oceanic plateaus from those of other tectonic settings. The mineralogy and crystallization sequence of the cumulates are similar to those of intra-plate magmas. Clinopyroxene predominates throughout, and orthopyroxene is only a minor component. Rocks of intermediate composition are absent, and hornblende is restricted to the uppermost massive gabbros within the sequence. The ultramafic cumulates are very depleted in light rare-earth elements (LREE), whereas the gabbros have flat or slightly enriched LREE patterns. The composition of the basaltic liquid in equilibrium with the peridotite, calculated using olivine compositions and REE contents of clinopyroxene, contains between 16% and 8% MgO and has a flat REE pattern. This melt is geochemically similar to other accreted oceanic plateau basalts, isotropic gabbros, and differentiated sills in western Ecuador. The Ecuadorian intrusive and extrusive rocks have a narrow range of epsilonNd(i) (+8 to +5) and have a rather large range of Pb isotopic ratios. Pb isotope systematics of the San Juan plutonic rocks and mineral separates lie along a mixing line between the depleted mantle (DMM) and the enriched-plume end members. This suggests that the Ecuadorian plutonic rocks generated from the mixing of two mantle sources, a depleted mid-oceanic ridge basalt (MORB) source and an enriched one. The latter is characterized by high (Pb-207/Pb-204)(i) ratios and could reflect a contamination by recycled either lower continental crust or oceanic pelagic sediments and (or) altered oceanic crust (enriched mantle type I, EMI). These data suggest that the San Juan sequence represents the plutonic components of an Early Cretaceous oceanic plateau, which accreted in the Late Cretaceous to the Ecuadorian margin.

Ectoparasites Ixodida Leach, 1817 on wild mammals in the state of Paraná, Brazil

A taxonomical and ecological study was made on 264 samples of 12 species of ectoparasite ixodides collected on wild mammals from several natural regions of Paraná state, Brazil. These species of ticks as their hosts are listed by their identified evolutive forms and capture locations. A review of the early studies on the Ixodida from South Brazil is made considering the frequency of the parasite species on each host concerning the geographic distribution of such species. This paper is a contribution to the knowledge of the Ixodidae ectoparasites species of wild mammals in Brazil.

Limnaea peregrina Clessin, 1882, Synonym of Lymnaea columella Say, 1817 (Gastropoda: Lymnaeidae)

A description is given of the shell, radula, renal region, reproductive system and egg capsules of topotypic specimens of limnaea peregrina Clessin, 1882. This investigation intends contributing to define the specific identity of that nominal species. A close anatomical comparison with Lymnaea columella Say, 1817 from Michigan, USA, shows that both forms are indistinguishable, giving support to previous inferences from some authors. Data on egg hatching are presented.

La formación de un humanista. Juan Ramón Masoliver (1910-1936)

Juan Ramón Masoliver perteneció a una generación privilegiada en cuanto a su formación. Promovió la revista Hèlix, altavoz del surrealismo en Catalunya, y estuvo en contacto con el núcleo surrealista francés. Conoció a James Joyce y Ezra Pound, dos intelectuales claves para su formación y su desarrollo cultural posterior. También en esta época entró en contacto con corrientes de pensamiento cercanas al fascismo. Con todas sus experiencias construyó un excéntrico personaje que, en su madurez, contaría con la simpatía de numerosos intelectuales.

Urban ecology of Triatoma infestans in San Juan, Argentina

This study was performed in an urban neighborhood of the capital city of the province of San Juan, Argentina. Erected as a housing complex, the place consists of 768 flats distributed in buildings of three and seven floors each. A survey was carried out in 33% of the dwellings, enquiring about the number of Triatoma infestans found indoors, stage of the bug development - nymph or adult - and how these insects had entered their homes. Adult T.infestans were found on all floors; 163 people (64%) had found them at least once, and 130 (51%) several times. Dispersal flight seems to have been the main mechanism of infestation by adult bugs in this area, and a total of 51% of the surveyed inhabitants reported that the insects had flown into their flats.

Rearing of Lymnaea columella (Say, 1817), intermediate host of Fasciola hepatica (Linnaeus, 1758)

The intermediate host of Fasciola hepatica, Lymnaea columella, collected in Belo Horizonte, Minas Gerais, Brazil, was reared in our laboratory. The aim of the current study was to standardize a rearing and maintenance technique. Two kinds of diet were tested: fresh lettuce (A) and rodent ration + 10% CaCO3 plus fresh lettuce (B). The age for the beginning of oviposition ranged from 27 to 57 days. Ten days after oviposition at 24.7°C, 100% eclosion occurred. The complete life cycle varied from 37 to 67 days. The average numbers of eggs per egg mass were 26.3 and 31.1 with diets (A) and (B), respectively. The lettuce and ration fed snails presented a increased growth although the difference was not statistically significant (p > 0.05). The mortality rate varied from 40 to 64% after 90 days. The maximum longevity was 183 days, 21.5 mm length and 11 mm wide. The methodology to mass breed and maintain these snails was found to be suitable in the laboratory

Genèse d'un champ scientifique : l'orthopédie comme fabrique d'une gymnastique. Du champ médical, de la spécialité orthopédique et des exercices corporels (1817-1847)

Cet article tente de circonscrire l'économie des discours gymniques médicaux et orthopédiques entre 1817 et 1847. Il s'agit de décrire l'institutionnalisation d'une investigation des corps (masculins et féminins) au sein de l'orthopédie. Nous analyserons la manière dont les acteurs de la spécialisation contribuent à alimenter le processus en systématisation des pratiques d'exercice corporel, en nous appuyant sur les controverses - méthodologiques, pratiques et symboliques -, inhérentes au processus de structuration de l'espace social médical, et particulièrement à la formation de l'orthopédie.
