[ES] Son escasos los estudios de resiliencia en contexto deportivo, siendo este un proceso que corresponde a un funcionamiento psicológico óptimo en los deportistas y representa una característica de la personalidad positiva que favorece su adaptación afrontando eficazmente las adversidades. El análisis de la relación entre resiliencia, optimismo y burnout puede establecer nuevas aportaciones. Es objeto de este estudio caracterizar estos constructos en judokas. Fueron evaluados 45 deportistas (9 mujeres y 36 hombres; edad:M =19.95,DT= 5.34). Los resultados señalan que el 38% de los judokas presenta una elevada resiliencia, con una significativa y negativa relación con sintomatología de burnout, relacionada con bajo optimismo. Se establece la Escala de Resiliencia (Ruíz, De la Vega, Poveda, Rosado y Serpa, 2012) como confiable y se concluye que resiliencia asociada a optimismo protege de sintomatología de burnout. Este trabajo facilita la elaboración de estrategias de intervención para el logro de un rendimiento óptimo deportivo.

[ES]Acto de presentación del libro que corre a cargo del Rector José Regidor, quien esta acompañado por Cristóbal García-Blairsy; los Catedráticos de la ULPGC Ángel Luque Escalona y Maximiano Trapero; Juan Luis Gómez Pinchetti, investigador del Banco Español de Algas; y el Catedrático emérito de la Universidad de La Laguna, Wolfredo Wilpret de la Torre. El libro recoge reseñas biográficas y artículos periodísticos sobre Guillermo García-Blairsy (1958-2012), Catedrático de Biología Vegetal de la Universidad de Las Palmas de Gran Canaria (ULPGC) y Director del Banco Español de Algas hasta su fallecimiento. El libro, que se divide en 13 epígrafes, cuenta con textos y aportaciones de más de una docena de personas, entre ellos: su padre Cristóbal García-Blairsy: su esposa Carolina Afonso Ferrera; el Catedrático de la ULL, Wolfredo Wilpret; el Catedrático de la ULPGC y director de la Tesis Doctoral de Guillermo García-Blairsy, Ángel Luque Escalona; los investigadores del Banco Español de Algas Antera Martel y Juan Luis Gómez; los colaboradores del antiguo Instituto de Algología Aplicada (actual Centro de Biotecnología Marina de la ULPGC) Daniel Robledo y Yolanda Fraile; el profesor del CSIC José Luis Mateo; el economista Jorge Dorta; los Catedráticos de la ULPGC, Octavio Santana y Javier Arístegui; Guillermo García-Blairsy Santandreu, hijo de Guillermo García-Blairsy que continuó con su último trabajo titulado ‘Policultivos Integrados’; Ziyadin Ramazanov, científico ruso que colaboró con el antiguo Instituto de Algología Aplicada en la década de los noventa; y María Jesús Hernández, periodista del periódico La Provincia/Diario de Las Palmas.

[ES]El desarrollo de las estructuras reproductoras (cistocarpos) en macroalgas rojas se ve afectado por factores abióticos (fotoperiodo, salinidad…) y endógenos (reguladores del desarrollo como el etileno o las poliaminas (PAs)); siendo estas últimas las principales responsables de la inducción del cistocarpo. Las PAs son moléculas ubícuas sintetizadas a través de una reacción enzimática mediada por la enzima ODC; por lo que conocer los mecanismos reguladores a nivel transcripcional del gen ODC es clave para el conocimiento del proceso reproductivo. Así, en el presente estudio se han identificado in silico diversos motivos conservados en la región 5 'UTR del gen ODC en la macroalga roja Grateloupia imbricata (GiODC) y se discute brevemente su presencia y posible implicación en diversos procesos metabólicos.

[EN]In this work we develop a procedure to deform a given surface triangulation to obtain its alignment with interior curves. These curves are defined by splines in a parametric space and, subsequently, mapped to the surface triangulation. We have restricted our study to orthogonal mapping, so we require the curves to be included in a patch of the surface that can be orthogonally projected onto a plane (our parametric space). For example, the curves can represent interfaces between different materials or boundary conditions, internal boundaries or feature lines. Another setting in which this procedure can be used is the adaption of a reference mesh to changing curves in the course of an evolutionary process...

[EN]In previous works, many authors have widely used mass consistent models for wind field simulation by the finite element method. On one hand, we have developed a 3-D mass consistent model by using tetrahedral meshes which are simultaneously adapted to complex orography and to terrain roughness length. In addition, we have included a local refinement strategy around several measurement or control points, significant contours, as for example shorelines, or numerical solution singularities. On the other hand, we have developed a 2.5-D model for simulating the wind velocity in a 3-D domain in terms of the terrain elevation, the surface temperature and the meteorological wind, which is consider as an averaged wind on vertical boundaries...

[EN]The meccano method is a novel and promising mesh generation method for simultaneously creating adaptive tetrahedral meshes and volume parametrizations of a complex solid. We highlight the fact that the method requires minimum user intervention and has a low computational cost. The method builds a 3-D triangulation of the solid as a deformation of an appropriate tetrahedral mesh of the meccano. The new mesh generator combines an automatic parametrization of surface triangulations, a local refinement algorithm for 3-D nested triangulations and a simultaneous untangling and smoothing procedure. At present, the procedure is fully automatic for a genus-zero solid. In this case, the meccano can be a single cube. The efficiency of the proposed technique is shown with several applications...

[EN]In this paper we propose a finite element method approach for modelling the air quality in a local scale over complex terrain. The area of interest is up to tens of kilometres and it includes pollutant sources. The proposed methodology involves the generation of an adaptive tetrahedral mesh, the computation of an ambient wind field, the inclusion of the plume rise effect in the wind field, and the simulation of transport and reaction of pollutants. We apply our methodology to simulate a fictitious pollution episode in La Palma island (Canary Island, Spain)...

[EN]A numerical model for the evaluation of solar radiation in different locations is presented. The solar radiation model is implemented taking into account the terrain surface using two-dimensional adaptive meshes of triangles that are constructed using a refinement/derefinement procedure in accordance with the variations of terrain surface and albedo. The selected methodology defines the terrain characteristics with a minimum number of points so that the computational cost is reduced for a given accuracy. The model can be used in atmospheric sciences as well as in other fields such as electrical engineering, since it allows the user to find the optimal location for maximum power generation in photovoltaic or solar thermal power plants...

[EN]A three-dimensional finite element model for the pollutant dispersion is presented. In these environmental processes over a complex terrain, a mesh generator capable of adapting itself to the topographic characteristics is essential. The first stage of the model consists on the construction of an adaptive tetrahedral mesh of a rectangular region bounded in its lower part by the terrain and in its upper part by a horizontal plane. Once the mesh is constructed, an adaptive local refinement of tetrahedra is used in order to capture the plume rise. Wind measurements are used to compute an interpolated wind field, that is modified by using a mass-consistent model and perturbing its vertical component to introduce the plume rise effect...
