The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set is a registry of all stations conducted during the Tara Oceans Expedition (2009-2013). The registry provides details about the scientific interest of each station, including (1) the geographic context, (2) legal context, (3) the environmental features that were targeted, and (4) a detailed account of devices deployed during the station. Uniform resource locators (URLs) offer direct links to the corresponding (1) physical oceanographic context reports, (2) list of samples collected during the station, (3) environmental data published at PANGAEA, and (4) nucleotides data published at the European Nucleotides Archive (EBI-ENA).

En este trabajo se calcula la tasa media de incisión fluvial del río Darro (Granada, España) durante el periodo 1890-2010 en su tramo urbano (sector Alhambra-Valparaíso). Para ello se han utilizado fotografías históricas en las que aparece dicho río, a partir de las cuales se ha podido determinar la posición del cauce en el momento en el que se realizaron las fotografías. La comparación con los escenarios actuales de tales imágenes ha permitido determinar la diferencia de altura del cauce a través de medidas de cotas absolutas realizadas mediante teodolito. Esta metodología ha permitido estimar de modo cuantitativo un índice de encajamiento vertical medio del río de 1,05 cm/año para el periodo histórico considerado.

Analysis of the word lancea, of Hispanic origin after Varro, and of place names, people´s names and personal names derived from it. It confirms that the spear was the most important weapon in the Bronze Age, belonging to the iuventus and used as heroic and divine symbol. This analysis confirms also the personality of the Lusitanians, a people related to the Celts but with more archaic archaeological, linguistic and cultural characteristics originated in the tradition of the Atlantic Bronze in the II millennium BC. It is also relevant to better know the organisation of Broze and Iron Age societies and the origin of Indo-Europeans peoples in Western Europe and of pre-Roman peoples of Iberia.

En el presente trabajo se analiza la manera en la que el dramaturgo valenciano Andrés Rey de Artieda diseñó los diferentes espacios dramáticos por los que transcurre la acción de su única pieza teatral conocida: Los amantes. Compuesta poco después de 1577, se trata de una obra deudora de los parámetros dramatúrgicos de su tiempo, pues el componente literario del texto dramático predomina claramente sobre el espectacular. Estamos ante un tipo de teatro fundamentado en la palabra y muy poco en lo visual.Sin embargo, ya se perciben en el texto ciertos rasgos de innegable modernidad, que es el asunto que me ha interesado a la hora de acercarme a él. Mi objetivo será demostrar el dinamismo con el que se producen los cambios de espacio dramático a lo largo de la trama argumental para subrayar que Rey de Artieda tenía ya asumidas algunas de las innovaciones que desembocarán en el teatro nacional español unas décadas más tarde.

The paper aims to interpret the political situation in Poland after 2015 double elections in terms of non-Marxian historical materialism. According to presented interpretation the taking power by Law and Justice Party not only limits the scope of influence of the previous ruling party but can lead to significant redistribution of political power, economic profits and intellectual influence. In the last part of paper, the prognosis about future development of situation in Poland is proposed

Background and Purpose—Most large acute stroke trials have been neutral. Functional outcome is usually analyzed using a yes or no answer, eg, death or dependency versus independence. We assessed which statistical approaches are most efficient in analyzing outcomes from stroke trials. Methods—Individual patient data from acute, rehabilitation and stroke unit trials studying the effects of interventions which alter functional outcome were assessed. Outcomes included modified Rankin Scale, Barthel Index, and “3 questions”. Data were analyzed using a variety of approaches which compare 2 treatment groups. The results for each statistical test for each trial were then compared. Results—Data from 55 datasets were obtained (47 trials, 54 173 patients). The test results differed substantially so that approaches which use the ordered nature of functional outcome data (ordinal logistic regression, t test, robust ranks test, bootstrapping the difference in mean rank) were more efficient statistically than those which collapse the data into 2 groups (2; ANOVA, P0.001). The findings were consistent across different types and sizes of trial and for the different measures of functional outcome. Conclusions—When analyzing functional outcome from stroke trials, statistical tests which use the original ordered data are more efficient and more likely to yield reliable results. Suitable approaches included ordinal logistic regression, test, and robust ranks test.

In most anatomical studies developed with mammals, the tongue is described as highly differentiated among different species. However, studies on the tongue of aquatic mammals are still limited as compared to those on terrestrial mammals. The aim of this study was to describe the tongue morphology of the Franciscana dolphin (Pontoporia blainvillei) using macroscopic observations, light, and scanning electron microscopy. Microscopically, the dorsal surface was covered by a keratinized stratified epithelium. Salivary gland acini were found on the middle and caudal third of the tongue. The dorsal surface was totally covered by filiform papillae with a connective tissue core and a connective tissue structure round in shape in the middle and caudal regions. Microsc. Res.

Este año se conmemora el 150 Aniversario del natalicio de uno de los grandes pensadores que ha trascendido sus tiempos, José Martí. En justo honor a él iniciamos nuestra relatoría del V Encuentro Internacional sobre Globalización y Problemas del Desarrollo con dos de sus bellos aforismos: Patria es Humanidad. Y decía también: “el AMOR a la Patria no es el amor ridículo a la tierra, ni a las yerbas que pisan nuestras plantas, es el odio invencible a quien la oprime, es el rencor eterno a quien la ataca."”Entre el 10 y el 14 de febrero, los más de 1500 participantes en este evento, procedentes de 41 países, han enaltecido el AMOR que les inspira la Patria Grande, participando en intensas jornadas de análisis y reflexión que fortalecen las convicciones y compromisos colectivos a favor de una Globalización alternativa, porque la actual, oprime y ataca a la Humanidad.
