Le rôle des associations de patients face au don d'organes en Suisse romande [Organ donation and the role of patients' associations in Western Switzerland].

In the context of lay mobilization in health-related areas, this article addresses the role and activities of patients' associations in connection with organ donation, on the basis of interviews carried out with thirty members of transplant patients' associations in the French-speaking part of Switzerland. First, we describe the three main categories of activities conducted by these associations. While self-help and public awareness activities are predominant, policy-oriented actions are marginal. Then, we examine the factors likely to explain why these associations have a limited capacity to be active, especially in the public sphere. Such a lack of social visibility is all the more important in the current political context, characterized by the implementation of a national action plan designed to improve organ donation.

Ana Ozores y su papel en el cuarto acto de Don Juan Tenorio

A vueltas con la Crónica del rey don Rodrigo

The paper discusses the problem of the literary genre of the Crónica sarracina from a peninsular and european points of view. It is considerer through the prism of a new kind of fiction, related to history and an incipient realism, which grows up along the 15th century. Moreover, it reveals new fragments inspired by Pedro de Corral from the catalan version of Seneca’s tragedies and from the Libro de los doce sabios

De Francisco a Marco Antonio Aldana pasando por Gaspar

It is traditionally considered that the «Aldana», whom Gaspar Gil Polo praises at the end of his «Canto de Turia» (1564), was Francisco de Aldana, the «divino». It is nonetheless more probable that it was in fact rather the Valencian poet, Marco Antonio Aldana, almost forgotten today, but very much in the public eye within the cultivated circles of the end of the sixteenth century Valencia

En torno al cardenal Don Gil Álvarez de Albornoz y el platero sienés Andrea Petrucci: el relicario de la mano de Santa Lucía y el cáliz de San Segundo

Este artículo trata de la complicada y hasta ahora inédita historia de la llegada a España de dos obras cumbres de la orfebrería sienesa del s. XIV en plata con esmaltes translúcidos: el relicario de la mano de Santa Lucía en la catedral de Toledo y el cáliz de San Segundo en la catedral de Ávila. La importación de estos dos importantísimos objetos devocionales y litúrgicos, ambos firmados por el platero sienés Andrea Petrucci, está relacionada con la estancia en Italia del cardenal don Gil de Albornoz, arzobispo de Toledo y posteriormente cardenal de San Clemente y Santa Sabina y legado papal. El mecenazgo del cardenal castellano y de su círculo en Italia explica la comisión y adquisición de estas piezas, cuyos accidentados itinerarios desembocarían finalmente en Toledo y en Ávila.

Avaliação da qualidade de sedimentos - estudo de caso: sub-bacia do Ribeirão Espírito Santo, afluente do Rio São Francisco

This study evaluated the environmental impact resulting from surface water and sediment contamination by metals in a watershed affected by a tailing basin that controls effluents coming from a zinc-ore beneficiation plant. The studies combined assessments of sediment chemistry (exceedances of sediment quality guidelines), benthic assemblage structure and acute and chronic ecotoxicity. The results showed that the levels of metal contamination in sediments are not yet enough to cause deleterious effects to the biota. However, the ecotoxicity tests indicated the occurrence of chronic effects, demonstrating that other factors, as the use of fertilizers, could also be a source of contamination.

Composição química volátil, em diferentes estádios de maturação, de manga 'Tommy Atkins' produzida no Vale do São Francisco

The effect of the maturation stages on the volatile chemical composition of mango fruit cv. Tommy Atkins, cultivated in São Francisco Valley, was investigated using SPME. GC/MS and GC-FID analysis allowed the identification of 32 compounds, consisting mainly of monoterpenes. δ-3-Carene was the major component in all the stages, while α-terpinolene, trans-β-caryophyllene e α-pinene succeded each other as the second most abundant constituent, during the ripening. The aroma of the ripe fruit was characterized by presence of short-chain ethyl esters (C2-C6), whereas the green mango contained the highest concentration of δ-3-carene. Furthermore, some terpenes were detected exclusively at one of the stages.

Concentrações e associações geoquímicas de Pb e Zn em sedimentos do rio São Francisco impactados por rejeitos da produção industrial de zinco

Surface sediments from the River São Francisco were analyzed to investigate the impact, due to the presence of metals (Cd, Cu, Pb, Zn) in wastes from a metallurgical industry in the city of Três Marias/MG, Brazil. The concentrations and geochemical associations of Pb, Zn and trace metals associated with the minerals employed in zinc production were measured. Sediments close to discharge locations were highly contaminated with Pb (332-512 μg g-1) and Zn (7872-10780 μg g-1), with values decreasing rapidly due to dilution and hydraulic sorting. Evaluation of toxicity according to the Consensus-based Sediment Quality Guidelines indicated for Cd, Pb and Zn a high probability of adverse effects on aquatic biota at these sites.
