    El ser humano tiene un condicionamiento muy profundo: el de ser reconocido por alguien como otro ‘alguien’, es decir, el de ser amado. De ahí la necesidad imperiosa de nacer en el ámbito familiar capaz de llevar a cabo las funciones que la vida social necesita. Por razón de solidaridad –valoración del otro como otro yo de cuyo bien soy responsable en la medida en que puedo influirle–, los propios derechos y obligaciones están limitados por análogos derechos y obligaciones ajenos, y, por supuesto, por la propia naturaleza de derecho u obligación

    En este trabajo se analiza la correlación entre la dimensión fractal de diferentes tipos de costas en Andalucía en función de la escala de digitalización y tipo de costa. Para ello se han digitalizado, a diferentes escalas que van 1:1.000 a 1:20.000, tramos significativos de la costa andaluza utilizando ortofotografías de alta resolución. Para testar la metodología desarrollada, los tramos elegidos son de una amplia variedad morfológica, como playas abiertas, costas acantiladas, sectores con amplias infraestructuras y marismas mareales. Los resultados del análisis, plasmados en el cálculo de la dimensión fractal para cada tipo de costa, vierten información sobre la importancia de la escala en las mediciones costeras y cómo varía su impacto en función de las características de la costa.The correlation between the fractal dimension of different types of costs in Andalusia in terms of digitizing scale and type of expense is analyzed in this work. Significant sections of the Andalusian coast were digitized at different scales ranging from 1:1,000 to 1:20,000, by means of the use of high resolution orthophotos. In order to test the developed methodology, the chosen sections show a wide morphological variety, as open beaches, coastal cliffs, sectors with large infrastructures and tidal marshes. The results of the analysis, reflected in the calculation of the fractal dimension for each type of expense, provide information about the importance of scale in coastal measurements and how their impact varies depending on the characteristics of the coast

    Atypical Western Mediterranean deep water formation during winter 2005

    The meteorological conditions in winter 2005, with anomalously low precipitation and unusual persistency of northerlies over the NW Mediterranean, caused a large extension both in time and space of deep convection processes. As a consequence, where convection typically gives rise to the Western Intermediate Waters (WIW) a New Western Mediterranean Deep Water (N-WMDW) was produced, slightly denser (+0.01kg m−3), warmer (+0.05ºC) and saltier (+0.03) than the usual WMDW. Moreover, near the continental slope, a cascading of colder and even denser water was found (-0.1ºC and +0.025 kg m−3), formed over the shelf (C-WMDW). In both cases it appears the high surface salinity as a responsible for the excess of density. The origin of this higher surface salinity is discusse

    A mesoscale index to describe the regional ocean circulation around the Balearic Islands

    Historical oceanographic surveys carried out around the Balearic Islands (western Mediterranean) suggest two different scenarios for the regional ocean circulation. In one scenario, occurring during cold winters, cool water is formed at intermediate layers (100–300 m) in the Gulf of Lions. This Western Mediterranean Intermediate Water (WIW) usually moves southward reaching the Balearic Channels, deflecting the warmer Levantine Intermediate Water (LIW) coming from the Eastern Mediterranean, and even blocking the Ibiza Channel. On the other hand, during mild winters, less WIW is formed and then LIW flows through the channels, appearing at their characteristic depths. The oceanographic surveys around the Balearic Islands (1985–2004) have provided a qualitative index, indicating the presence or not of WIW in the Ibiza Channel, based on the analyses of θS diagrams. A quantitative index based on mean water temperature between 100 and 300 m depth in the channels may also be defined. Both indexes, the qualitative and the quantitative, give consistent information on WIW presence for the period 1985–2004, however, both are short in time and have gaps in the series. In order to obtain a longer and continuous index for WIW presence and then for regional circulation, air–sea heat fluxes at the Gulf of Lions during winter months were obtained from the meteorological NCEP/NCAR reanalysis dataset and compared with other meteorological data such as surface air temperature. The standardized air temperature anomalies at 1000 hPa in the Gulf of Lions during winter (December–March) has been shown to be the simplest and best indicator of absence/presence of WIW in the Balearic Islands channels in late spring. Values above 1.0 of the standardized temperature anomaly would indicate absence of WIW in the Ibiza Channel. The high correlation obtained with available in-situ oceanographic data allows the use of this index as an indicator of presence of WIW and then of different regional circulation scenarios backwards in time and in those years for which the oceanographic data are missing or scarc

    This study represents a novel proof of concept of the clinical utility of miRNAs from exhaled breath condensate (EBC) as biomarkers of lung cancer (LC). Genome-wide miRNA profiling and machine learning analysis were performed on EBC from 21 healthy volunteers and 21 LC patients. The levels of 12 miRNAs were significantly altered in EBC from LC patients where a specific signature of miR-4507, miR-6777-5p and miR-451a distinguished these patients with high accuracy. Besides, a distinctive miRNA profile between LC adenocarcinoma and squamous cell carcinoma was observed, where a combined panel of miR-4529-3p, miR-8075 and miR-7704 enabling discrimination between them. EBC levels of miR-6777-5p, 6780a-5p and miR-877-5p predicted clinical outcome at 500 days. Two additional miRNA signatures were also associated with other clinical features such as stage and invasion status. Dysregulated EBC miRNAs showed potential target genes related to LC pathogenesis, including CDKN2B, PTEN, TP53, BCL2, KRAS and EGFR. We conclude that EBC miRNAs might allow the identification, stratification and monitorization of LC, which could lead to the development of precision medicine in this and other respiratory diseases

    Seasonal and interannual variability of dissolved oxygen around the Balearic Islands from hydrographic data

    Oceanographic data obtained between 2001 and 2011 by the Spanish Institute of Oceanography (IEO, Spain) have been used to characterise the spatial distribution and the temporal variability of the dissolvedoxygen around the Balearic Islands (Mediterranean Sea). The study area includes most of the Western Mediterranean Sea, from the Alboran Sea to Cape Creus,atthe border between France and Spain. Dissolved Oxygen (DO) at thewatersurface is found to be in a state of equilibrium exchange with the atmosphere. In the spring and summer a subsurface oxygen supersaturation is observed due to the biological activity, above the subsurface fluorescence maximum. Minimum observed values of dissolved oxygen are related to theLevantine Intermediate Waters (LIW). An unusual minimum of dissolved oxygen concentrations were also recorded in the Alboran Sea Oxygen Minimum Zone. The Western Mediterranean Deep Waters (WMDW) and the Western Intermediate Waters (WIW) show higher values of dissolved oxygenthanthe Levantine Intermediate Waters due to their more recent formation. Using these dissolved oxygen concentrations it is possible to showthat the Western Intermediate Waters move southwards across the Ibiza Channel and the deep water circulates around the Balearic Islands. It has also been possible to characterise the seasonal evolution of the different watermassesandtheir dissolved oxygen content in a station in the Algerian sub-basin.

    Digital and programmable economy applications: A smart cities congestion case by fuzzy sets

    Get PDF
    Currently, cities are facing great challenges such as the population growing, citizen wellbeing, externalities management or environmental deterioration. The search for solutions are making significant inroads into the incorporation of ICT in them and subsequent large-scale digitalization such as programmable economy (PE) applications, offering the possibility to develop new approaches over these issues, in particular which related to sustainability management. Operating under a fuzzy numbers methodology and FIS (Fuzzy Inference System), the present exploratory work shows a new approach to city urban congestion management by deploying PE applications, which include some disruptive inputs such as the Internet of value, blockchain/DLT (distributed ledger, technology), smarts contracts, digital assets and the monetization, all of this combined with the human motivation
