    La calidad y fragilidad visual del paisaje adquiere relevancia con el objeto de la gestión en el marco de la planificación del paisaje y Se pone en evidencia espacialmente su nueva dimensión jurídica en la ordenación del territorio en la Comunidad Valenciana. Se revisan sus procedimientos de análisis que se concretan con ejemplos de experiencias en esta comunidad, para diferentes escalas y objetivos. También se específica la conveniencia de la integración de ambas para determinar el valor de la conservación del paisaje. La reglamentación actual se encauza en estos términos, ofrece la oportunidad de desarrollo de estos atributos para la efectiva planificación del paisaje y los utiliza para la propuesta estratégica territorial por medio de los instrumentos de ordenación, gestión y mejora del paisaje.

    El objetivo del presente Proyecto Fin de Carrera es dar a conocer principalmente los primeros barcos de vela latina de la zona del Mediterráneo y poner de manifiesto las ventajas y beneficios que supone el uso de la tecnología por la que se puede digitalizar un modelo del año 1907. Gracias a ello se obtienen los planos de forma y se permite hacer una recreación de cómo estaba construido. Finalmente, recopilar información sobre las técnicas utilizadas y funciones a las que se dedicaban los barcos. En la elaboración del Proyecto se ha seguido una metodología basada en el desarrollo de las diferentes fases que se relacionan a continuación. 1ª Fase: Obtención de datos sobre los orígenes, construcción, distribución y función de los barcos de vela latina de la costa mediterránea. 2ª Fase: Adquisición de las formas de tres modelos a través de una estación total. Seleccionando el apropiado para realizar el Proyecto. 3ª Fase: Digitalización del modelo seleccionado en 3D con la finalidad de obtener las formas del casco. 4ª Fase: Recreación del proceso de construcción en 3D de la estructura del barco bajo una normativa llamada LLOYD’S REGISTER OF SHIPPING 5ª Fase: Análisis de los pesos del barco y cálculo de las curvas hidrostáticas.Escuela Técnica Superior de Ingeniería Naval y OceánicaUniversidad Politécnica de Cartagen

    [EN] Aim of study: To verify and prioritise a set of sustainable forestry indicators using the Analytic Hierarchy Process (AHP). Area of study: Participants were Spanish; indicators were meant to be applied in forest management units (FMUs) under Mediterranean conditions. Material and methods: An AHP questionnaire was developed and sent to experts. Main results: the set of indicators aimed to be comprehensive. Indicators were ranked and the ranking allows ascertaining what aspects are more relevant in relation to Mediterranean sustainable forestry. Issues like regeneration or habitats conservation got high values, whereas others like hunting activity were not seen as important by most experts. Research highlights: - Sustainable forest management (SFM) considerations for Mediterranean forests. - Indicators adapt to ecosystem services.Spanish Ministry of Economy and Competitiveness (Project ECO2011-27369); the Regional Council of Education, Culture and Sports (Valencia, Spain) financed a PhD fellowship to PVD (Ref.

    Urban green indicators: a tool to estimate the sustainability of our cities

    Full text link
    [EN] In Europe, more than 70% of the population lives in an urban area. All the challenges related to land use conflicts, demographic changes, climate resilience and human well-being are concentrated inside the cities, since the population is already living in urban areas, which are more and more compact and dependent on grey infrastructure. In this context, urban green infrastructure represents a sustainable solution to maintain the benefits and services provided by urban ecosystems and an efficient urban planning tool to face the urban challenges. The sustainability of our cities can be reached adopting an innovative vision using the concept of ecosystem services of the urban green infrastructure. Different initiatives to assess the benefits provided by green infrastructure have emerged in the last decade. However, very few take into account the whole range of services provided by urban green infrastructure. The present article provides a systematic search and synthesis of the most important literature to review indicators of urban green infrastructure. The main goal is to give an insight of how urban green infrastructure is measured in practice. Results show the set of ecosystem services that are being considered when assessing sustainability of green infrastructure and identify the most recurrent indicators at the different scales. This work is expected to contribute to the improvement of the evaluation of green infrastructure effectiveness for providing benefits for urban dwellers.This work was supported by the European Union’s Horizon 2020 research and innovation programme under the project Green Cities For Climate and Water Resilience, Sustainable Economic Growth, Healthy Citizens and Environments with reference 730283.Tudorie, CM.; Gielen, E.; Vallés-Planells, M.; Galiana, F.

    To confirm the diagnostic accuracy of candidate biomarkers in stroke-associ- ated pneumonia (SAP), we prospectively enrolled ischemic stroke patients with NIHSS ≥ 10 on admission from March-2016 to August-2017. Blood samples were collected at baseline, 24 and 48 h after stroke onset. Biomarkers (MR- proADM, suPAR, SAA) were determined by immunoassays. Regarding biomarkers, MR-proADM at 24 h (P = 0.04) and both suPAR and SAA at 48 h (P = 0.036 and P = 0.057) were associated with pneumonia. The combination of SAA > 25.15 mg/dL and suPAR> 3.14 ng/mL at 48 h had 80% sensitivity and 95.8% specificity when both biomarkers were above the cut-off. The evalu- ated biomarkers represent promising tools to be evaluated in future large, prospective studies on SAP. An accurate SAP diagnosis by thorax CT might help to reduce variability in such studies

    Socio-Demographic Variables and Successful Aging of the Angolan Elderly

    The proportion of elderly people is growing faster than any other age group. Amongst them, the group of oldest old is indeed the segment of the elderly population with the fastest growth rate. The increase in the proportion of elderly in the Angolan population makes research on this area badly needed. Within the theoretical framework of successful aging, the study aims to test for sociodemographic group differences in perceived health, life satisfaction, and social relations in Angolan elderly. The dependent variables are three of the components of what has been called successful aging. Data came from a cross-sectional survey of elderly people living in Luanda. 1003 Angolan elderly were surveyed on sociodemographic information, perceived health, life satisfaction, and social support. MANOVAs were calculated to test for mean differences in the dependent variables. Results permit to conclude that the factors associated with the largest differences on the Angolan elderly’s quality of life and social relations were age (becoming oldest old) and institutionalization. The interactions of several factors with age pointed out that the oldest old were clearly a group in which the decreased quality of life due to becoming oldest old could not be compensated by other factors, as it was the case in the group of young old

    Landscape adaptation to climate change : Local networks, social learning and co-creation processes for adaptive planning

    Get PDF
    The development of legitimate, operative, and feasible landscape adaptation planning for climate change is dependent on the specific characteristics of the landscape and its inhabitants. Spatial patterns, culture, governance systems, socio-economic structures, planning methods, history, and collectively envisioned futures need to be accommodated. The literature suggests that landscape is a complex and dynamic socio-ecological system, the management and adaptation of which requires systemic and integrative approaches to respond to a wide variety of drivers of change, challenges, and interests. Based on activities developed in 15 European pilot landscapes, we identify some of the key factors and conditions affecting the generation of representative local networks for landscape adaptation to climate change. We illustrate how social learning and co-creation processes can be implemented in them and how their co-produced outcomes can help local communities overcome barriers and address critical issues in adaptive planning. Our results provide a framework for the creation of similar networks in other landscapes, exploring at the same time the interactions between the composition of networks, social learning, and the quality of the co-produced outputs as a fundamental step for the development of Landscape Adaptation Plans to Climate Change.Peer reviewe
