Variabilidad espacial y temporal del recurso surf en Cantabria

ABSTRACT: Surfing is a sport that has presented an enormous growth in the last years, increasing exponentially the number of people who practice and enjoy it. In this area, Cantabria is one of the leading regions in Spain, and it is for this reason that this work seeks to provide a quantitative response to the value and quality of the surfing resource and its application in the management and conservation of its áreas of interest in the region. A hybrid downscaling method has been developed that allows the precise evaluation of the characteristics of the incident waves in the main surfbreaks of the cantabric coast, being this scalable to all Spain and also worldwide. Making use of tools commonly used in oceanography, coastal engineering and data science, the historical record of oceanographic variables (wave height, period ...) of the last 40 years that is obtained allows statistical and climatic analysis of the beaches with better surfing conditions, which is useful in the management and planning of areas of interest to it, serving this work as a basis for a possible project of legal protection of the surfbreaks.RESUMEN: El surf es un deporte que ha presentado un crecimiento enorme en los últimos años, aumentando exponencialmente el número de personas que lo practican y disfrutan.

Se ha desarrollado un método de reducción de escala híbrido que permite evaluar con precisión las características del oleaje incidente en las principales rompientes del litoral cántabro, siendo este escalable a toda España y también mundialmente. Haciendo uso de herramientas comúnmente usadas en oceanografía, en ingeniería de costas y en ciencia de datos, el registro histórico de variables oceanográficas (altura de ola, periodo…) de los últimos 40 años que se obtiene permite analizar estadística y climatológicamente las playas con mejores condiciones de surf, lo que resulta de utilidad en la gestión y ordenación de los espacios de interés para el mismo, sirviendo este trabajo de base para un posible proyecto de protección legal de las rompientes o surfbreaks.Máster en Ciencia de Dato

Wing patterning genes and coevolution of Müllerian mimicry inHeliconiusbutterflies: Support from phylogeography, cophylogeny, and divergence times

Examples of long-term coevolution are rare among free-living organisms. Müllerian mimicry in Heliconius butterflies had been suggested as a key example of coevolution by early genetic studies. However, research over the last two decades has been dominated by the idea that the best-studied comimics, H. erato and H. melpomene, did not coevolve at all. Recently sequenced genes associated with wing color pattern phenotype offer a new opportunity to resolve this controversy. Here, we test the hypothesis of coevolution between H. erato and H. melpomene using Bayesian multilocus analysis of five color pattern genes and five neutral genetic markers. We first explore the extent of phylogenetic agreement versus conflict between the different genes. Coevolution is then tested against three aspects of the mimicry diversifications: phylogenetic branching patterns, divergence times, and, for the first time, phylogeographic histories. We show that all three lines of evidence are compatible with strict coevolution of the diverse mimicry wing patterns, contrary to some recent suggestions. Instead, these findings tally with a coevolutionary diversification driven primarily by the ecological force of Müllerian mimicry

New record of Leptosalenia barredai (Echinoidea) from the Albian of Comillas (Basque-Cantabrian basin)

Se reporta un nuevo registro del raro equínido Leptosalenia barredai Forner, 2014, que sólo había sido citado previamente en tres localidades y una única en la cuenca sedimentaria Vasco-Cantábrica. Se dispone y figuran dos ejemplares del yacimiento de Venta de la Vega de Comillas (Cantabria). Los nuevos datos confirman, de una parte, la existencia de L. barredai en la cuenca Vasco-Cantábrica y, de otra, la conexión entre esta y la cuenca del Maestrat durante el Albiense, a través de una amplio canal en lo que hoy es, aproximadamente, el valle del Ebro.A new record of the rare echinoid Leptosalenia barredai Forner, 2014 is reported, which had only been previously cited in three locations and a single one in the Basque-Cantabrian sedimentary basin. Two specimens from the Venta de la Vega of Comillas (Cantabria) outcrop are available and figured. The new data confirm, on the one hand, the existence of L. barredai in the Basque-Cantabrian basin and, on the other, the connection between it and the Maestrat basin during the Albian through a wide channel in what today, approximately, it is the Ebro valley

Analysis of reading comprehension session in a classroom of primary education.

RESUMEN: Comprender textos es una habilidad crucial en todos los ámbitos. Comprender textos que tocan temas desconocidos o abstractos y hacerlo en profundidad es muy demandante y complejo. Y eso es justamente lo que exige la escuela. Por eso los maestros deben poner en marcha sesiones de lectura en el aula que promuevan el desarrollo de dicha habilidad. Esas lecturas deben incluir un Episodio de Planificación, en la que se fijan metas, y un Episodio de Interpretación, en el que se discute sobre los contenidos centrales del texto y los alumnos tienen un papel relevante en esa discusión. Grabé y analicé una sesión de lectura en un aula de Educación Primaria con el de fin de comprobar si reúne esos requisitos, es decir, si es buena en términos de Organización, Contenido y Participación. En cuanto a Organización, la sesión alberga un Episodio de Planificación, pero la meta no está bien delimitada. Respecto a Contenido, la discusión gira en torno al texto, pero también hay momentos dedicados a discutir sobre otra materia, en concreto de la asignatura de Lengua Castellana, en la cual transcurre la sesión analizada. En cuanto a Participación, en general, los alumnos juegan un papel importante en la discusión. Todos estos resultados, junto con los obtenidos en estudios anteriores, nos dan pistas sobre los aspectos en los que los docentes podrían revisar su práctica para mejorar.ABSTRACT: Reading comprehension is a critical skill. Dealing with texts that cover unfamiliar topics and achieving Deep comprehension while doing so requires complex and demanding skills. School work requires students to do so, making teachers’ intervention crucial. In order to promote Reading comprehension skill teachers have to carry out effective reading sessions. Effective sessions are those that include a Planning Episode, in which she sets Reading goals, and an Interpretation Episode, in which both the teacher and the students discuss on the gist of the text. I analyzed a classroom Reading session, taking three aspects into account, namely, Organization, Contents and Participation. Regarding Organization, the session had a Planning Episode, but the Reading goal was not well defined. Regarding Contents, the discussion focused on the text, but there where also a number of comments addressing a different topic, in these case, about the subject of Spanish Language, where I made the analysis. Regarding Participation, overall, the students played a key role during the discussion. These results are in line with those obtained in prior research. In conjunction, these findings shed some light on the aspeccts that teachers should improve to provide students with effective training.Grado en Magisterio en Educación Primari

Three-dimensional submerged wall jets and their transition to density flows: Morphodynamics and implications for the depositional record

Jets that expand from an orifice into an ambient water body represent a basic flow model for depositional environments related to expanding flows. Momentum-dominated jets evolve into gravity-dominated density flows. To understand this transition and its sedimentological relevance, three-dimensional tank experiments with submerged wall jets were conducted, systematically varying parameters such as the initial density difference, bed slope, grain size and sediment supply. Bedform successions could be subdivided into those related to the jet and those related to the density flow. Jet deposits included early-stage bedforms, scours and mouth bars. Early-stage bedforms are asymmetrical dunes that spread concentrically from the orifice. Sediment entrainment by eddies from the expanding jets led to the formation of scours and mouth bars. Flows with lesser initial density difference produced more elongate scours. Conversely, scours became deeper for denser incoming flows. Coarser-grained sediment caused the formation of higher and steeper mouth bars and vice versa. The transition from momentum-dominated jets to gravity-dominated density flows occurred approximately at the mouth-bar crest. Hydraulic jumps were absent in the expanding jet regions and at the transitions to density flows. Instead, complex flow patterns and circulations were inferred from the velocity measurements within the scour and at the mouth-bar crests. Bedform trains related to the density flow were controlled by the grain size and sediment supply. Coarse-grained sediment and high supply rates caused strong mouth-bar aggradation and flow splitting, leading to the formation of bedform trains laterally adjacent to the mouth bar. Fine-grained sediment and low supply rates caused the formation of bedform trains downflow of the mouth bar. The symmetrical bedforms deposited by the density flows always displayed an in-phase relationship with the flow, indicating that they were antidunes. The experimental jet deposits resemble successions known from subaqueous ice-contact fans and deep water channel-lobe transition zones

Siglec-E promotes β2-integrin-dependent NADPH oxidase activation to suppress neutrophil recruitment to the lung

Siglec-E is a sialic acid-binding Ig-like lectin expressed on murine myeloid cells. It has recently been shown to function as a negative regulator of β2-integrin-dependent neutrophil recruitment to the lung following exposure to lipopolysaccharide (LPS). Here, we demonstrate that siglec-E promoted neutrophil production of reactive oxygen species (ROS) following CD11b β2-integrin ligation with fibrinogen in a sialic acid-dependent manner, but it had no effect on ROS triggered by a variety of other stimulants. Siglec-E promotion of ROS was likely mediated via Akt activation, because siglec-E-deficient neutrophils plated on fibrinogen exhibited reduced phosphorylation of Akt, and the Akt inhibitor, MK2206, blocked fibrinogen-induced ROS. In vivo imaging showed that siglec-E also promoted ROS in acutely inflamed lungs following exposure of mice to LPS. Importantly, siglec-E-promoted ROS were required for its inhibitory function, as the NADPH oxidase inhibitor, apocynin, reversed the siglec-E-mediated suppression of neutrophil recruitment and blocked neutrophil ROS production in vitro. Taken together, these results demonstrate that siglec-E functions as an inhibitory receptor of neutrophils via positive regulation of NADPH oxidase activation and ROS production. Our findings have implications for the inhibitory role of siglec-9 on human neutrophils in sepsis and acute lung injury
