Estructura y relleno sedimentario de la semifosa neógena de Vilanova (Garraf, Barcelona)

En el presente trabajo se aborda el estudio de una cuenca sedimentaria mediante la utilización conjunta de técnicas de cartografía geológica y datos de subsuelo, provenientes del análisis de sondeos mecánicos y de la determinación de las anomalías de la gravedad. La cuenca presenta una geometría asimétrica en forma de semigraben orientado segun la dirección regional ENE-OSO, controlado por fallas normales en dicha dirección en su límite NO, mientras que por el SE está delimitado por una discordancia. La existencia de un sistema asociado de fracturas, ortogonalmente dispuestas, complica el dispositivo anterior, resultando un basamento estructurado en bloques que configuran pequeñas subcuencas. La modelización gravimétrica de la cuenca en 3D ha permitido obtener un modelo de gran resolución para la geometria del basamento. El modelo geofísico obtenido ha sido contrastado con los datos provenientes de los sondeos...

Centrality and investment strategies at the beginning of industrialisation in mid-nineteenth-century Catalonia

We apply social networks analysis to the study of an important database on investment and companies" share in the Catalonia (Spain) of the nineteenth century. In contrast with most of the existing related literature, usually addressing power relationships across administration boards, we focus on the structure of interactions among individual investors and firms. Centrality analysis uncovers interesting roles played by certain economic sectors (e.g. textile and financial). Furthermore, the diverse composition (in terms of economic activity) of communities in the network (subgroups more densely connected internally than with the rest of the network) reveals a high investment diversification, which nicely agrees with a known characteristic of traditional Catalan business strategies.

Caracterizació arqueomètrica de les ceràmiques tardanes de la plaça del Rei de Barcelona

Un total de 40 ceràmiques tardanes, en la majoria de casos grolleres, que procedeixen de contextos de la segona meitat del segle VI-segle VII de les excavacions de la plaça del Rei de Barcelona, han estat caracteritzades arqueomètricament mitjançant fluorescència de raigs X (FRX), difracció de raigs X (DRX) i microscòpia òptica de làmina prima (MO). A la mostra estudiada, els resultats han permès establir l"existència de fins a 10 grups diferents, alguns dels quals clarament heterogenis, la qual cosa permet pensar que l"anàlisi d"un nombre més elevat de mostres hauria revelat un nombre encara més gran de produccions en el jaciment. Entre les produccions caracteritzades se n"ha identificat una de ceràmica comuna fina de producció local o regional, així com nou de ceràmiques grolleres tant importades com locals i/o regionals.

Assessment of the water chemistry and the macroinvertebrate community changes produced during the creation of the new Llobregat river mouth (Barcelona, NE Spain)

In 1999, a set of coordinated projects and investments whose principal objective was to transform Barcelona into one of the main distribution points of southern Europe resulted in the relocation of the Llobregat River mouth. The mouth was relocated by draining the old river mouth and constructing a new one. The aim of this study was to characterise the physico-chemical properties and the aquatic macroinvertebrate communities of the new river mouth and to monitor the changes experienced by the estuarine environment during its creation. A sampling point was established in the river 1.8 km upstream from its connection with the new mouth, and two sampling points were established in the new mouth. Samples of water and macroinvertebrates were collected every two months from May 2004 to June 2005, covering the periods before (from May to September 2004) and after (from September 2004 to June 2005) the new mouth was connected to the river and the sea. During the period before its connection to the river and the sea, the new mouth was functionally similar to a lagoon, with clear waters, charophytes and a rich invertebrate community. After the connection was completed, seawater penetrated the river mouth and extended to the connection point with the river (approximately 3.9 km upstream). An increase in conductivity from 4-6 mS cm 1 to 24-30 mS cm 1 caused important changes in the macroinvertebrate community of the new mouth. An initial defaunation was followed by a colonisation of the new mouth by brackish-water and marine invertebrate species. Due to its design (which allows the penetration of the sea) and the decreased discharge from the lower part of the Llobregat River, the new mouth has become an arm of the sea

Stratigraphy and petrology of the Miocene Montjuic delta: (Barcelona, Spain).

The Neogene rift in the Catalan Coastal Ranges, which is located in the NE part of the Eastern Iberian Margin, corresponds to a system of grabens formed at the nort h - we s t e rn edge of the Valencia Trough. In the central part of the Catalan Coastal Ranges are the Valls - Peneds half-graben in the onshore and the Barcelona half-graben in the offshore, which are separated by the Garraf and the Collserola-Montnegre horsts. Montjuc hill is a tilted block, which is located to the S of the Barcelona city, between the Collserola-Montn egre horst and the Barcelona half-graben . The Middle Miocene section of Montjuc is constituted by an alternation of conglomerate, sandstone, mudstone and marlstone beds. The Montjuc section was divided into four lithostratigraphic units from base to top: (1) The Morrot conglomerate and sandstone Unit, interpreted as delta plain deposits; (2) the Castell conglomerate, sandstone and mudstone Unit considered as proximal delta front deposits; (3) the Miramar marlstone Unit attributed

Determinación de la paleosalinidad, mediante la relación Br/Cl, en las sales de la cuenca potásica catalana (Sallent, Barcelona, España)

Debido a su acumdación en las salmueras de las cubetas de deposición evaporítica, el Br se concentra progresivamente en los ultimos precipitados de los cloruros. La relación Br/Cl ha sido utilizada (BOEKE y EITEL, 1923; D'ANS y KÜHN, 1944) para determinar variaciones en la concentración de la salmuera durante la deposición evaporítica. Para la determinación cuantitativa del Br y CL en varias muestras recogidas en la explotación de Sallent, se ha utilizado la fluorescencia de rayos X.

Tobacco control policies in hospitals before and after the implementation of a national smoking ban in Catalonia, Spain

Background: Diverse projects and guidelines to assist hospitals towards the attainment of comprehensive smoke-free policies have been developed. In 2006, Spain government passed a new smoking ban that reinforce tobacco control policies and banned completely smoking in hospitals. This study assesses the progression of tobacco control policies in the Catalan Network of Smokefree Hospitals before and after a comprehensive national smoking ban. Methods: We used the Self-Audit Questionnaire of the European Network for Smoke-free Hospitals to score the compliance of 9 policy standards (global score = 102). We used two crosssectional surveys to evaluate tobacco control policies before (2005) and after the implementation of a national smoking ban (2007) in 32 hospitals of Catalonia, Spain. We compared the means of the overall score in 2005 and 2007 according to the type of hospital, the number of beds, the prevalence of tobacco consumption, and the number of years as a smoke-free hospital. Results: The mean of the implementation score of tobacco control policies was 52.4 (95% CI:45.4-59.5) in 2005 and 71.6 (95% CI: 67.0-76.2) in 2007 with an increase of 36.7% (p < 0.01). The hospitals with greater improvement were general hospitals (48% increase; p < 0.01), hospitals with > 300 beds (41.1% increase; p < 0.01), hospitals with employees' tobacco consumption prevalence 35-39% (72.2% increase; p < 0.05) and hospitals that had recently implemented smoke-free policies (74.2% increase; p < 0.01). Conclusion: The national smoking ban appears to increase tobacco control activities in hospitals combined with other non-bylaw initiatives such as the Smoke-free Hospital Network.

La publicación de artículos en las áreas de ciencias sociales y humanidades analizada a partir de los sistemas de información sobre investigación: el caso de las Universidades de Barcelona y Girona

Los sistemas de información sobre investigación y actividad científica de las universidades permiten complementar los datos que ofrecen las bases de datos multidisciplinares internacionales tales como WoS o Scopus, especialmente en disciplinas cuya cobertura no es suficientemente exhaustiva. En el presente estudio se analizan algunas características sobre los artículos y revistas publicados en las áreas de Ciencias Sociales y Humanidades por profesores e investigadores de dos universidades catalanas. Los datos han sido extraídos a partir de bases de datos que permiten el acceso libre a los registros de la producción de ambas instituciones académicas. Se concluye la importancia del acceso abierto a este tipo de registros además de la existencia de diferencias entre las áreas de conocimiento en aspectos tales como calidad, nivel de colaboración, porcentaje de divulgación, idioma de publicación, aunque existe una tendencia general a un mayor uso relativo de la lengua inglesa.

Redes sociales y negocios. La red de inversión del Banco de Barcelona en la economía catalana a mediados del siglo XIX

The appearance of the Banco de Barcelona involved the formation of an investment compact network between its directors. In this work we studied how this investment network grew within a larger one, the one formed by the major investors in Catalonia during the period 1815-1866, as well as the role played by the top executives of the Bank inside it. Our findings indicate that some of the directors of the Bank held a central position in the main Catalan investors" network. This important role guaranteed reliable information on the progress of businesses. This information not only favored the operations of the institution, but also allowed its directors to take investment decisions inside the network. Moreover, the Bank interconnects individuals who were associated with different investors" sectors, which made the institution coalesced around an investing core with different important influences and connections.

Aportació al coneixement de l"herbari Trèmols de l"Institut Botànic de Barcelona.

The herbarium BC-Trèmols was created during the second half of the 19th century by the Catalan chemist and botanist Frederic Trèmols Borrell. Between 1930 and 1960, the technician Antoni Marcos carried out a thorough review. The current collection consists of approximately 9000 specimen sheets; is made up of 58 volumes reordered by Marcos,two volumes with the original structure, four boxes of Hieracium and 85 boxes with additional material. Up to now 22 volumes and four boxes of Hieracium have been computerized (3695 specimens); we made an inventory at genus level of all volumes, and we computerized the original catalogue of the herbarium and the existing taxonomical fiches. We have also developed a preliminary inventory of the contents of the extra boxes. The analysis of these 3695 herbarium specimens clearly shows that it mainly consists of samples obtained by exchange (67.1%) especially within the Société Helvétique pour l"Échange des Plantes and the Societat Botànica Barcelonesa. Among the materials studied we found two specimens regarded as interesting from a taxonomical and/or nomenclatural point of view (isotypes of Silene holzmanii Heldr. ex Boiss. and of Arenaria minutiflora Loscos). Therefore, the main interest of the herbarium lies in the diversity of the geographical provenance of plants, which makes of this collection one of the first"pan-European herbaria" in Catalonia.
