Gaur egun drogomenpekotasuna gizarte modernoko arazo larri bat bezala ulertuta eta nahasmen mentala, drogomenpekotasunarekin oso lotuta dagoen patologia dela kontuan izan arren, patologia bikoitz hau pairatzen dituzten pertsonen % 85ak ez du beharrezko atentzioa jasotzen. Izan ere, ehuneko txiki bat da integrazio zentro edo osasun eta birgizarteratze zentro batean bizi direnak. Arazo honen aurrean eta proposatzen diren zentro hauen kalitatea hobetu nahian, jarduera fisikoaren zentzuzko erabilera bat beharrezkoa dela ikusi da. Horregatik, jarduera fisikoak duen garrantzia aspektu desberdinetatik ikusi daiteke, hala nola, egoera fisikoa hobetzeko zein droga kontsumoa murrizteko duen eragina eta birgizarteratzearen bitartez, bizi kalitatean duen efektu positiboa. Gradu amaierako lan honen bitartez, jarduera fisikoak, nahasmen mentalak eta drogomenpekotasuna duten pertsonetan zein eragina duen aztertu nahi da.

Ondoren, jarduera fisikoak patologia honetan duen eragina ikusi eta honek esparru honetan duen garrantzia zein erabilgarritasuna ikusi da. Beste alde batetik, zentro espezializatu baten egoeran oinarrituta, 12 asteko jarduera fisiko entrenamendu bat proposatzen da nahasmen mentalak eta drogomenpekotasuna duten eta integrazio zentro batean bizi direnen pertsonentzat. Azkenik, gure formakuntzaren bitartez esku hartze berri honen aurrean eskaini dezakegun onurak kontuan hartuta, jarduera fisiko eta kiroleko adituek alor honetan dugun garrantzia eta beharra aldarrikatzen da

Lipids at the crossroad of α-synuclein function and dysfunction: Biological and pathological implications

Since its discovery, the study of the biological role ofα-synuclein and its pathologicalimplications has been the subject of increasing interest. The propensity to adoptdifferent conformational states governing its aggregation and fibrillation makes thissmall 14-kDa cytosolic protein one of the main etiologic factors associated withdegenerative disorders known as synucleinopathies. The structure, function, and toxicityofα-synuclein and the possibility of different therapeutic approaches to target theprotein have been extensively investigated and reviewed. One intriguing characteristic ofα-synuclein is the different ways in which it interacts with lipids. Though in-depth studieshave been carried out in this field, the information they have produced is puzzling andthe precise role of lipids inα-synuclein biology and pathology andvice versais still largelyunknown. Here we provide an overview and discussion of the main findings relating toα-synuclein/lipid interaction and its involvement in the modulation of lipid metabolismand signaling.Fil: Alza, Natalia Paola.

Viability study of sailing propulsion combined with a conventional system

For many years now, sails have been used as a propulsion system. At present, they are restricted to recreational/sport crafts since the appearance of the first steam vessels in the beginning of the 19 th century. But in the last years, due to the increase of fuel price and the pollution of the environment, it is being studied the possibility to introduce again the sail as a propulsive method combined with other conventional systems. In this paper, it is studied the viability of using a sail as a propellant with other conventional systems of propulsion. After considering the concept of apparent wind, the range of use of this complementary propulsion is presented. The calculation methodology, the numerical simulations and the wind inputs from a specific route are also included

Soluciones Flotante para Aerogeneradores: Plataforma Spar

La calidad del recurso eólico en alta mar, el crecimiento de la industria eólica, el desarrollo sostenible además de otros factores extrínsecos, tales como los riesgos de las centrales nucleares, la vulnerabilidad de los mercados ante crisis en países productores de petróleo y las altas emisiones de CO2 por parte de las centrales de ciclo combinado son algunos de los factores que, cada vez más, justifican la adopción de soluciones sostenibles de origen renovable donde la energía eólica flotante presenta un futuro prometedor. Las plataformas Spar son una de las posibles opciones. En el presente trabajo se muestra un procedimiento metódico de diseño de una plataforma Spar analizando las ventajas y los inconvenientes de este tipo de estructuras para lograr el cometido de soportar un aerogenerador de gran potencia en mar abiert

Stability Criteria for Sailing Vessels

What do you know about sailing yacht stability? Which are the peculiarities of the stability of a sailing yacht? Is there any supposition different from those applied in conventional ships? If you have to verify the stability of your yacht, would you be sure of which criteria you should applied? The aim of this paper is to answer these questions among others. The authors assume that the readers of this paper come from varied backgrounds and experience. Some of you may not be totally familiar with these stability requirements whereas others may use them every day. It is hoped that this paper will be some enlightenment for the former and be an interesting review for the latter. In this paper the philosophy of sailing yacht stability will be presented. It will be also examined the criteria in force in countries such as Spain, United Kingdom, United States and The Netherlands among others and the assumptions upon which they are based will be highlighted. In order to clarify ideas two reference sailing yacht will be subjected to different criteria and compared their severity

Drag Reduction trough Special paints Coated on the hull

The economic recession, the environmental impact as well as the continuous fossil fuel consumption encourage actions that focus on saving energy. In the vessels sector, one of the main objectives has always been to reach a hydro-dynamically optimum hull which gave the desired speed with minimum power. Hydrodynamic drag is basically divided into two parts: a) the friction between the water and the hull, and b) the wave generation due to the free-surface air-water. Presented in this paper, is the research which evaluates the possibility of friction-drag reduction by means of the coat of special paints on the hull. The study has been applied to a fishing cooperation vessel on which hydrodynamic aspects had already been analyzed by the ETSI Navales Model Basin. Two plates with different paints have been tested with a wet surface equivalent to the model used in the previous hydrodynamic test. Numerical simulations with a viscous code, which includes a roughness module, have also been carried out. The complete three dimensional system, including the free surface effect, has been considered. With these simulations it is expected to validate the roughness module of the commercial cod

Computational study of sail performance of a racing yacht

Es importante entender las caracteristicas del flujo y el comportamiento de las velas tanto para los navegantes como para los disenadores que quieren tener un empuje eficiente de la embarcacion. En este trabajo, se presenta la simulacion del flujo de aire alrededor de las velas, con una geometria final impuesta, y con un codigo CFD reproduciendo las medidas a escala real. El codigo numerico utilizado es un CFD viscoso basado en las ecuaciones RANS. Se han considerado tres combinaciones de velas: dos mayores y una mayor mas genova y los parametros estudiados principalmente son la sustentacion, resistencia, centro velico y el coeficiente de presion sobre las velas. Se han comparado los resultados obtenidos con datos experimentales y otros datos numericos procedentes de otros estudios. El estudio concluye que hay una buena concordancia entre los calculos numericos y los datos a escala real, mostrando la importancia de la utilizacion de estas herramientas numericas. It is important to understand flow characteristics and performance of sails for both sailors and designers who want to have an efficient thrust of yacht. In this article, the airflow around yacht sails with imposed final geometry is simulated using a CFD (Computational Fluid Dynamics) code reproducing full scale measurements. The code is a commercial viscous CFD based on Reynolds-averaged Navier-Stokes (RANS) equations. Three sets of sails are considered: two mainsails alone and one set of mainsail with jib and the parameters in study are mainly the lift, drag, center of effort and pressure coefficient over the sails. The results are compared with both experimental data and numerical computations obtained from other studies. It is concluded that there is good agreement between numerical calculations and full scale data, showing the importance of the use of numerical tools
