las especies de insectos más hermosas, más interesantes y más representativas
de nuestra maravillosa fauna entomológica, escribiendo un
pequeño capítulo acerca de la ecología de la Graéllsia isabelae, la mariposa
que, primero conocida del centro de la Península, fué luego
encontrándose en diversos parajes poblados de pino silvestre y que
los franceses capturaron en los Alpes de su país en época reciente ;
especie que tiene en su haber una bibliografía cuantiosa y a veces
pintoresca, y sobre la que, desde su «nacimiento» al conjuro de la
perspicaz mente de Graells, se han contado cosas peregrinas, ha sido
objeto de activo comercio entre los aficionados a mariposas, se tuvo
como especie exclusivamente española, se encontró en el país vecino,
adonde llegó en la época terciaria, según unos, y en el siglo xx, según
otros, y cuyo desarrollo a expensas del pino silvestre, con exclusión
de toda otra especie que le sirviera de alimento, era cosa consagrada
entre los lepidopterólogos de todo el mundo.Peer reviewe

Andanzas americanas de Pedro Ordóñez de Ceballos en dos comedias del Siglo de Oro
No full textEl catálogo, tantas veces considerado escaso, de comedias americanas del Siglo de Oro español se ha ido ampliando sucesivamente en los últimos años. A él deben añadirse las comedias que tratan las andanzas indianas del clérigo Pedro Ordóñez de Ceballos: dos piezas de Alonso Remón y una comedia de fr. Francisco de Guadarrama, con dos continuaciones anónimas sobre cuya autoría se especula hoy. El autor de este artículo traza una semblanza de Ordóñez de Ceballos, inventaría sus obras, establece sus caracteres como modelo dramático a partir de lo que él mismo declara en sus prólogos a esas comedias, localiza estas relevantes piezas y las analiza en pormenor.
The catalogue, so often considered scarce, of American dramas of the Spanish Golden Age has been succesively expanded in recent years. Several more comedies on the american ramblings of the clergyman Pedro Ordóñez de Ceballos should be added: two theater pieces by Alonso Remón, a drama by fr. Francisco de Guadarrama, along with two anonymous sequels whose authorship is speculated about today. The author of this article draws a biography of Ordóñez de Ceballos, enlists his works, establishes his features as a dramatic model, starting from what Ordóñez himself states in his prologues to those comedies, locates those relevant pieces, and analyses them in depth

REMdb as a framework for collaborations in environmental radioactivity research
No full textUnder the terms of Article 36 of the Euratom Treaty, European Union Member States (MSs) shall periodically communicate to the European Commission (EC) information on environmental radioactivity levels. These results have been introduced into the Radioactivity Environmental Monitoring database (REMdb) of the EC Joint Research Centre (JRC) sited in Ispra (Italy) (https://rem.jrc.ec.europa.eu/RemWeb/).
The initial purpose of the REMdb was to bring together environmental radioactivity data produced in the aftermath of the Chernobyl accident, and to store them in a harmonised manner. Thus the database has two main objectives: 1) to collect the environmental radioactivity data gathered through the national environmental monitoring programs of the MSs to prepare comprehensive annual monitoring reports; and 2) to keep a historical record of the radiological accidents for scientific studies.
Nowadays, containing nearly two million records of radioactivity levels in milk, water, air and mixed diet received from the MSs, the REMdb offers the scientific community dealing with environmental radioactivity endless research opportunities.
The records stored in REMdb prior to 2007 are fully public, while the access to the data from the 2007-2015 period can be granted only after explicit request. This fact makes the REMdb a useful and unique pillar on which to perform environmental radioactivity studies at the European level, and which can be considered as a liaison platform between national and international scientific groups conducting collaborative research.
Example of collaboration: Analysis of 7Be surface concentrations
As a valuable proof of this use, the present work provides an overview of the research activity undertaken by a friendly scientific collaboration network created by the University of Belgrade, the University of Bologna and the REM group of the JRC in the study of the 7Be surface concentrations recorded across Europe. These sets of results represent one of the first attempts to better understand the 7Be distribution in Europe, as well as the impact of tropopause height (TPH) and other meteorological parameters exert on it.First, spatial and temporal distribution of the 7Be specific activity in surface air was carried out using the long-term database (1984–2011) of 34 sampling sites, focusing on describing the impact of the latitude and solar cycle on yearly and monthly concentrations (Hernández-Ceballos et al., 2015). Further, a cluster analysis was instead applied to identify spatial patterns in 7Be concentrations in Europe: results showed the presence of three distinguishable cluster groups (south, central and north of Europe) with clear differences between concentrations in both intensity and time trends, and with a latitudinal distribution of the sampling stations (Hernández-Ceballos et al., 2016a). These regions were also identified in an analysis of seasonal and spatial patterns of extremely high 7Be surface concentration (values above 95th percentile in each site) recorded over the 2001–2010 period across Europe (Ajtić et al., 2016a). This study reported that most of the extremes occur over the March–August period, while at least 10 % of the total number of extremes take place during autumn and winter. In Ajtić et al., 2016b these “cold extremes” were analysed in more detail, showing three meteorological scenarios associated with their occurrence in northern Europe. In these works, the impact of TPH on 7Be, and therefore, on the spatial distribution of 7Be in Europe, was also suggested. The influence of TPH on 7Be was further investigated in a separate study (Hernández-Ceballos et al., 2016b), which showed a larger TPH influence on 7Be during summer and a large spatial variability of TPH on 7Be levels with a clear gap between southern and northern Europe in the area of the polar front jet
