Creación, dinamización y puesta en valor del destino turístico emergente: campiña turística sevillana

En el presente artículo intentamos mostrar un modelo de dinamización de La Campiña Turística Sevillana. Para ello, comenzaremos con la creación y justificación del destino turístico, diseñaremos el producto y lo orientaremos hacia la demanda y segmentos turísticos adecuados. Ello está justificado en que esta área geográfica, en los últimos cinco años, ha apostado firmemente por la diversidad y el desarrollo integral del destino, con la vista puesta en un desarrollo turístico sostenible y de calidad, que ha contribuido a mejorar la calidad de vida de su sociedad. La clave turística de este destino está en la diversidad histórica y paisajística que la caracteriza. En estos momentos, Campiña Turística se encuentra en una situación favorable de cara al turismo potencial. Por ello, distintos organismos públicos como Prodetur, S.A., aúnan esfuerzos para unir siete localidades no pertenecientes a una organización territorial determinada, formar el destino turístico emergente Campiña Turística, y dinamizarlo cumpliendo todos los requisitos vigentes en la normativa en materia turística, dotándolo de todos los instrumentos necesarios para poder elevarlo hacia la excelencia.In this article we attempt to provide a dinamization model of the Tourism in the Sevillian Countryside (Campiña Turística Sevillana). To do this, we start with the creation and justification of the destination; we will design the product and demand- driven and appropriate tourist segments. This is justified in this geographic area, as in the last five years, is strongly committed to diversify and arrive at the integral development of destination, in order to reach a sustainable tourism development and quality, which has helped improve the quality of life of their society. The key of this tourist destination is the historic and scenic diversity that characterizes it. At present, Tourism in the Sevillian Countryside is in a good position facing the tourism potential. Therefore, various public bodies as Prodetur SA join forces to connect seven locations without territorial organization determined to form the emerging tourist destination Tourism in the Countryside, doing a dinamization, meeting all requirements in the tourism industry standards, and providing it with all the tools they need to raise it toward excellence

La oferta académica del nuevo grado en turismo en la EUEE de la Universidad de Sevilla y las necesidades formativas demandadas por el sector turístico

El trabajo que se presenta realiza un estudio comparativo entre la oferta académica del Grado en Turismo en la Escuela Universitaria de Estudios Empresariales de la Universidad de Sevilla, en fase de aprobación, y las necesidades formativas que demanda el sector turístico. Mediante una encuesta a entidades, empresas y corporaciones, con las que la EUEE mantiene acuerdos de práctica, se intenta detectar los puntos fuertes y débiles que la oferta formativa del Centro tiene para el sector profesional. Los resultados muestran que los módulos que desarrollan competencias transversales son más valorados que los que desarrollan competencias específicas modulares. Además, todas las materias del Grado tienen una valoración media o alta. Finalmente, los estudiantes realizan actividades de prácticas en empresa que poseen escaso nivel creativo y baja responsabilidad en la organización.This paper presents a comparative study between the offer of an academic Tourism degree at the Business School in the University of Seville, in the process of adoption and the training needs required by the tourism industry. Through a survey of institutions, companies and corporations, with which EUEE maintains placement agreements, we try to identify the strengths and weaknesses of the training Center for the professional sector. The results show that the modules that develop transversals skills are more valued than those that develop specific modules. In addition, all subjects have a medium or high assessment. Finally, students execute work placements that have little creativity and low-level of responsibility in the organization

Fully coupled TFM-DEM simulations to study the motion of fuel particles in a fluidized bed

In the present work, novel numerical simulations using a hybrid model are carried out to study the motion of objects, representing fuel particles, in a pseudo-2D fluidized bed. The hybrid model combines the continuum treatment of the gas phase with the possibility to treat different solid phases either as continuum, or discrete. In the present case, both the gas and the dense phase of the bed are modelled as continuum phases, as typically done in two-fluid model simulations, whereas fuel particles are simulated as discrete entities whose movement affects, and can be affected by the dense phase motion (i.e. fully coupled TFM-DEM simulations). The results obtained from the model are qualitatively and quantitatively compared with reported experimental findings available in the literature. Firstly, the motion of the fuel particle with regards to the bubble phase and dense phase is proved to be realistic. Secondly, the location probability of the particle in the simulated bed is calculated and compared with the experimental data. Then, the ballistic path followed by the particle in the freeboard is also compared with experimental measurements. These results show good agreement between experiments and simulation. The numerical results reflect the same behaviour during the ascending and descending motion of the fuel particles as that observed in the experiments. The results also show that the most probable locations of the particles predicted by the simulations are consistent with the experimental findings, both inside the fluidized bed and in the freeboard. Overall, the hybrid model tested shows quite promising results, which indicates the potential usability of the model.This work has been partially funded by the Spanish Government (Project DPI2009-10518) and the Autonomous Community of Madrid (Project S2009/ENE-1660).Publicad

Thermo-economic optimization of a novel confined thermal energy storage system based on granular material

Concentrated solar power is a suitable technology for production of green electricity. However, to attain a uniform electricity production, concentrated solar power should be coupled with large Thermal Energy Storage (TES) systems. Among the different technologies of TES systems, storage of sensible heat in granular material is widely used due to its simple operation. These TES systems store energy as an increase of temperature of a large mass of small solid particles, through which a fluid circulates exchanging heat. TES systems are typically operated in a fixed bed regime, maximizing their exergy output, thus limiting the maximum allowable velocity of the fluid flow. In this work, a novel confined bed is proposed to mechanically prevent the motion of the solid particles conforming the TES system even for high fluid velocities, to guarantee that the exhaust temperature of the fluid is maximum during a discharge process. In this novel confined bed, a thermocline evolves from bottom to top of the system, separating the low and high temperature of the bed during the discharge process. An analytical model was applied to describe the evolution of the thermocline and the effect of the different operating parameters on the thermocline thickness. The effect of the thermocline thickness was combined with a thermo-economic analysis of a confined bed TES system proposed for a case of study. The new confined bed here proposed was optimized considering thermodynamics aspects, namely the fluid exergy increment in the bed, and economic factors, specifically the total investment cost of the TES system. The optimization resulted in low values of the fluid velocity, between 0.2 and 0.4 m/s, but still higher than the minimum fluidization velocity of sand particles of 750 mum, justifying the requirement of a confined bed, and low bed aspect ratios, between 0.25 and 0.9, to prevent excessively high fluid pressure drops. However, the bed aspect ratio increases significantly for higher granular material particle sizes, up to a ratio of bed height to diameter of 3 for a particle size of 10 mm and a TES demand time of 6 h.This research was funded by the Spanish Government under the project STORESOL, reference number PID2019-109224RA-100.

Distribución espacial y mapeo de curculio elephas gyllenhal en encina (quercus ilex l.)

Curculio elephases una de las plagas carpófagas más importantes en encinares y castañares en España. El presente trabajo se llevó a cabo durante un periodo de cuatro años en una dehesa del sur de España, y se ha estudiado la distribución espacial usando métodos clásicos (índices de infestación, índices de dispersión, ajustes a distribuciones estadísticas) y elaborando mapas de densidad larvaria. Nuestros principales resultados fueron: 1) alta incidencia de C. elephasen las encinas de la parcela de muestreo, presentándose de un 32 a un 57,4 % de las bellotas infestadas por el balanino; 2) los índices de dispersión, las distribuciones estadísticas y los mapas de densidad larvaria confirman que C. elephaspresenta una distribución agregada y una estabilidad espacio-temporal de sus poblaciones a lo largo del periodo de estudio; 3) relación directa entre la infestación y la densidad larvaria y el tamaño medio de las bellotas. Estos resultados indican que la distribución espacial anual de C. elephasfue heterogénea y que posiblemente esté relacionada, entre otros factores, con la distribución de las encinas con bellotas en las dehesas y de su calidad y grado de madureThe weevil, Curculio elephasis one of the most important carpophagous pest of holm oaks and chestnut trees in Spain. The present paper performed during a four year period in an economically exploited holm oak forest area in Southern Spain, investigated the chestnut weevil spatial distribution using both classic methods (infestation indices, dispersion indices, fitting to statistical distributions) and by elaborating larval density maps. Our main findings were: 1) a very high incidence of C. elephaswas detected on the holm oaks of the experimental plot, with 32-57.4 % of the acorns infested by the weevil; 2) dispersion indices, statistical distributions and larval density maps confirmed that C. elephashad an aggregated distribution and the spatio-temporal stability of its population over long term periods; 3) a direct relation was detected between the weevil infestation and larval density indices and the medium size of the acorns. These results indicate that the annual spatial ditribution of C. elephaswas heterogeneous and that it was possibly related, among other factors, to the distribution of holm-oak with acorns inside the forest and to their quality and degree of ripenes

Resistance and recovery of benthic marine macrophyte communities to light reduction: Insights from carbon metabolism and dissolved organic carbon (DOC) fluxes, and implications for resilience.

A crucial factor in the long-term survival of benthic macrophyte communities under light-reduction stress is how they balance carbon metabolism during photosynthesis and respiration. In turn, the dissolved organic carbon (DOC) released by these communities, which can be highly light-dependent, stands as a source of carbon, fuelling marine communities and playing an important role in the ocean carbon sequestration. This is the first study to evaluate light-reduction stress and recovery in the seagrass Zostera noltei and the macroalga Caulerpa prolifera. Light reduction led to a significant decrease in the production of both communities from autotrophic to heterotrophic. Results indicated that most of the DOC released by vegetated coastal communities comes from photosynthetic activity, and that the net DOC fluxes can be greatly affected by shading events. Finally, both communities showed resilience underpinned by high recovery but low resistance capacity, with C. prolifera showing the highest resilience to unfavourable light conditions

Practical recommendations for skin preparation of Surgical Site

Resumen La búsqueda de estrategias para la disminución de la infección de sitio operatorio (ISO) es una prioridad, dado el impacto que ésta tiene en los resultados de la atención de los pacientes. Recientemente ha tomado gran relevancia en la prevención de la ISO, la preparación prequirúrgica de la piel del paciente como uno de los factores clave, en los que se puede intervenir y disminuir el riesgo. En los últimos años han aparecido revisiones exhaustivas dedicadas no solo a la comparación de las soluciones antisépticas, y técnica de aplicación, también acerca de la importancia del baño pre operatorio, uso de cintas y compresas quirúrgicas impregnadas con antisépticos y el recorte de cabello preoperatorio. En esta publicación se describen los hallazgos más importantes relacionados con la preparación antiséptica de la piel del paciente y se propone un protocolo con recomendaciones prácticas para ser implementado en las instituciones del país. Se incluyen recomendaciones basadas en niveles de evidencia sobre el uso de las soluciones antisépticas (yodopovidona, clorhexidina, clorhexidina mas alcohol, entre otras) con énfasis en las ventajas y desventajas de cada una de ellas.Abstract The search for strategies for reduction of Surgical Site infection (SSI) is a priority, given the impact that infections have on the outcome of the patients. The preoperative patient skin antisepsis, has recently gained greater significance in the prevention of SSI, as one of the critical factors, which can be intervened and can reduce the risk of infection. In recent years, comprehensive investigations have been published not only dedicated to the comparison of antiseptic solutions, application techniques, but also about the importance of preoperative bathing, use of surgical tapes and dressings impregnated with antiseptics, and preoperative shaving. This review outlines the key findings related to the preoperative patient's skin antisepsis and offers a protocol with practical recommendations to be implemented in the institutions of our country. It provides evidence based recommendations about the use of antiseptic solutions (povidone iodine, chlorhexidine, chlorhexidine plus alcohol, etc.) with emphasis on the advantages and disadvantages of each one
