The management of lifeguards in natural acuatic spaces (beaches)

Este estudio nace con la necesidad de establecer criterios básicos y descripción de recomendaciones para mejorar el nivel de atención de los socorristas acuáticos profesionales en los espacios acuáticos naturales, concretamente en el trabajo realizado en las playas, con el objetivo de aumentar la seguridad de estas zonas de baño. El estudio se ha desarrollado en la Comunidad Autónoma de Cataluña, concretamente en tres playas de varios municipios de la provincia de Barcelona. Se puede afirmar que tras esta investigación la mayor parte de los socorristas acuáticos que han participado en el estudio valoraron positivamente las medidas y criterios propuestos, asumiendo que con los mismos se puede desempeñar mejor su trabajoThis study arises from the need to establish basic criteria and the description of recommendations to improve the level of responsiveness of lifeguards in natural aquatic areas, specifically in the work done on the beaches, in order to increase the safety of these bathing areas. The study was developed Cataluña, in three beaches of different municipalities in the province of Barcelona. We can aver after this research that most of the lifeguards who participated in the study value positively the proposed measures and criteria, through the assumption that these features help improve their wor

Nutritional status and physical condition in active vs. sedentary elderly people

El objetivo del estudio fue conocer la relación entre el estado nutricional, la adherencia a la dieta mediterránea y el nivel de condición física de personas mayores. Participaron 168 personas mayores de 65 años (grupo control=84 personas activas y grupo experimental=84 personas sedentarias). La adherencia a la dieta mediterránea fue medida con el cuestionario MEDIS-FFQ, el nivel de práctica de actividad física mediante una pregunta creada a tal efecto, y las diferentes pruebas físicas con los instrumentos específicos. Los resultados revelaron que el 63.1% manifestó baja adherencia a la dieta mediterránea y el 34.5% alta, teniendo los sujetos sedentarios mayor adherencia que los activos (p≤0.05; 46.4% vs. 22.6%). Los sujetos activos tienen mejor condición física que los sedentarios (p≤0.001). Por tanto, la mayor parte de las personas mayores deben incrementar su adherencia a la dieta mediterránea y la práctica de actividad física como mecanismo de mejora de su saludThe objective of the study was to know the relationship between nutritional status, adherence to the Mediterranean diet and the level of physical displacement of older people. 168 people older than 65 years participated (control group = 84 active people and experimental group = 84 sedentary people). Adherence to the Mediterranean diet was measured with the MEDIS-FFQ questionnaire, the level of physical activity practice through a question created for that purpose, and the different physical tests with the specific instruments. The results revealed that 63.1% showed low adherence to the Mediterranean diet and 34.5% high, according to the sedentary subject’s greater adherence than the active ones (p≤0.05, 46.4% versus 22.6%). Active subjects have better physical income than sedentary people (p≤0.001). Therefore, most elderly people want to increase their adherence to the Mediterranean diet and the practice of physical activity as a mechanism to reduce their healt

Non-abelian D=11 Supermembrane

We obtain a U(M) action for supermembranes with central charges in the Light Cone Gauge (LCG). The theory realizes all of the symmetries and constraints of the supermembrane together with the invariance under a U(M) gauge group with M arbitrary. The worldvolume action has (LCG) N=8 supersymmetry and it corresponds to M parallel supermembranes minimally immersed on the target M9xT2 (MIM2). In order to ensure the invariance under the symmetries and to close the corresponding algebra, a star-product determined by the central charge condition is introduced. It is constructed with a nonconstant symplectic two-form where curvature terms are also present. The theory is in the strongly coupled gauge-gravity regime. At low energies, the theory enters in a decoupling limit and it is described by an ordinary N=8 SYM in the IR phase for any number of M2-branes.Comment: Contribution to the Proceedings of the Dubna International SQS'09 Workshop ("Supersymmetries and Quantum Symmetries-2009", July 29 - August 3, 2009. 12pg, Late

On Non Commutative G2 structure

Using an algebraic orbifold method, we present non-commutative aspects of $G_2$ structure of seven dimensional real manifolds. We first develop and solve the non commutativity parameter constraint equations defining $G_2$ manifold algebras. We show that there are eight possible solutions for this extended structure, one of which corresponds to the commutative case. Then we obtain a matrix representation solving such algebras using combinatorial arguments. An application to matrix model of M-theory is discussed.Comment: 16 pages, Latex.

Die Wettbewerbsfähigkeit der arabischen Mittelmeerländer im internationalen Vergleich

6 p.- Papers presented at the International Workshop "The Conservation of Subterranean Cultural Heritage", held 25-27 March 2014, in Seville, Spain.Paranhos constitutes one of the main water galleries excavated in the granite substratum of Porto City (Portugal) to gather the groundwater for public use during the past five centuries. This gallery is a Subterranean Cultural Heritage site with a potential use for underground geotourism under safe conditions. An environmental monitoring programme has been conducte in the site comprising rapid multi-parameters. This programme has allowed the identification of urban-induced causes of contamination of the aquifer and internal tunnel atmosphere (waste-water and gas leakage). This study has also comprised the determination of effective radioactive dose in different sectors of the tunnel for potential visitors based on 222Rn studies.Financiado con el Proyecto (HAR-2010-11432-E) Red de Ciencia y Tecnología para la Conservación del Patrimonio CulturalPeer reviewe

Basement-Cover Relationships and Their Along-Strike Changes in the Linking Zone (Iberian Range, Spain): A Combined Structural and Gravimetric Study

Contractional deformation in the transition between the Iberian and Catalan Coastal Ranges (Linking Zone) generated both thin-skinned structures detached in low-strength Triassic units and basement-involved structures. To evaluate their extent and relative contribution to the overall structure, we carried out a study combining structural geology and gravimetry. New gravity data (938 stations) and density determinations (827 samples) were acquired and combined with previous existing databases to obtain Bouguer anomaly and residual Bouguer anomaly maps of the study area. Seven serial and balanced cross sections were built, their depth geometries being constrained through the 2.5-D gravity modeling and the 3-D gravity inversion that we accomplished. The residual Bouguer anomaly map shows a good correlation between basement antiforms and gravity highs whereas negative anomalies mostly correspond to (i) Meso-Cenozoic synclines and (ii) Neogene-Quaternary basins. Cross sections depict a southern, thick-skinned domain where extensional, basement faults inherited from Late Jurassic-Early Cretaceous times were inverted during the Cenozoic. To the north, we interpret the existence of both Triassic-detached and basement-involved deformation domains. The two deformation styles are vertically overlapped in the southernmost part of the Catalan Coastal Ranges but relay both across and along strike in the Eastern Iberian Range. These basement and cover relationships and their along-strike variations are analyzed in terms of the interplay between structural inheritance, its obliquity to the shortening direction, and the continuity and effectiveness of Triassic décollements in the study area

Guía de práctica clínica para la elección del fluido de restauración volémica perioperatoria en los pacientes adultos intervenidos de cirugía no cardiaca

Esta Guía de Práctica Clínica responde a preguntas clínicas sobre seguridad en la elección de fluido (cristaloide, coloide o Hidroxietilalmidón 130) en pacientes que precisan restauración volémica en el periodo perioperatorio de cirugía no cardiaca. A partir del resumen de la evidencia, se elaboraron las recomendaciones siguiendo la metodología GRADE. En esta población se sugiere la fluidoterapia basada en la administración de cristaloides, (recomendación débil, calidad de la evidencia baja). En las situaciones en las que la restauración volémica no se alcance sólo con cristaloides, se sugiere utilizar coloides sintéticos (Hidroxietilalmidón 130 o gelatina fluida modificada) en lugar de Albúmina 5% (recomendación débil, calidad de la evidencia baja). La elección y dosificación de coloide deberán basarse en las características del producto, comorbilidad del paciente y experiencia del anestesiólogo

Petrophysical properties in the Iberian Range and surrounding areas (NE Spain): 1-density

We introduce the first map of density data in Northeastern Spain which can help in the interpretation of gravimetric surveying. The background map is a simplified version of the Geode continuous geological cartography (scale 1:200.000) of the Iberian Range and Ebro basin. These maps are synthetic and homogeneous maps based on previous 1:50, 000 scale geological maps (MAGNA). The map uses the ETRS89 datum and UTM coordinates (30T northern zone) and covers an area of 140, 000 sq km. The compiled data shown in the map come from previous papers of the region (˜ 700 points) as well as from more than 800 additional points developed in the course of an exploratory project focused on the underground characterization of a potential CO2 reservoir in the so-called ‘Linking Zone''. The new data accomplish some basic criteria; they are accurately georeferenced and lithology, stratigraphic age and other technical details about the measurements (e.g. means and error) and methods are fully displayed
