SUSTAINABLE AGRICULTURE MANAGEMENTS TO CONTROL SOIL EROSION
2021
[EN] High rates of soil erosion compromise sustainable agriculture. In rainfed agricultural fields, erosion rates several orders of magnitude higher than the erosion rates considered tolerable have been quantified. In Mediterranean rainfed crops such as vineyards, almonds and olive groves, and in the new sloping citrus and persimmon plantations, the rates of soil loss make it necessary to apply measures to reduce them to avoid collapse in agricultural production. Managements such as weeds, catch crops and mulches (straw and pruning remains) are viable options to achieve sustainability. This work applies measurements through plots, simulated rainfall experiments and ISUM (Improved Stock-Unea…
Quantification of poisons for Ziegler Natta catalysts and effects on the production of polypropylene by gas chromatographic with simultaneous detecti…
2020
[EN] This article describes a new simultaneous method for the analysis of sulfur-type poisons, hydrocarbons and permanent gases affecting the productivity of the Ziegler Natta catalyst during the synthesis of polypropylene on an industrial scale in a fluidized-bed reactor. The identification was achieved employing a configuration of the seven-valve chromatographic system, with events at different times, allowing distribution of the sample through multiple columns, and finally reaching the helium ionization detectors of pulsed discharge, flame ionization and mass spectrometry. The results obtained show a good precision of the method used because the variability was less than 1.02% in area an…

The urban revitalization of the coastal tourist destinations: An alternative for the Valencian Mediterranean tourist municipalities
2021
espanolLos municipios del litoral mediterraneo valenciano aumentaron sensiblemente su superficie construida por la irrupcion de la actividad turistica a mediados del siglo XX. A pesar de las ventajas iniciales, los problemas surgidos sobre el espacio urbano, por la naturaleza del modelo de desarrollo turistico utilizado, los dirigen hacia una perdida progresiva de su atractivo turistico. Ante esta circunstancia, se hace necesario intervenir sobre el espacio urbano, no solo para renovar el destino turistico sino tambien para corregir los problemas urbanos generados durante las ultimas decadas en unos municipios que supeditaron sus decisiones exclusivamente a las necesidades turisticas. Una o…
Monitoring multidimensional phenomena with a multicriteria composite performance interval approach
2021
[EN] In the last two decades, the construction of composite indicators to measure and compare multidimensional phenomena in a broad spectrum of domains has increased considerably. Different methodological approaches are used to summarise huge datasets of information in a single figure. This paper proposes a new approach that consists in computing a multicriteria composite performance interval based on different aggregation rules. The suggested approach provides an additional layer of information as the performance interval displays a lower bound from a non-compensability perspective, and an upper bound allowing for full-compensability. The outstanding features of this proposal are: 1) a dis…
Evaluation of the Use of a City Center through the Use of Bluetooth Sensors Network
2019
In order to achieve the objectives of Smart Cities, public administrations need to take measures to regulate mobility, which undoubtedly requires a high level of information and sensorization. Until the implementation of the connected vehicle takes place, it is still necessary to install sensors to obtain information about mobility. Bluetooth sensors are becoming a useful tool due to the low cost of equipment and installation. The use of Bluetooth sensors in cities, with short distances between sensors, makes it necessary to propose new classification algorithms that allow the trips of pedestrians and vehicles to be differentiated. This article presents the study carried out in the city of …
A risk evaluation framework for the best maintenance strategy: the case of a marine salt manufacture firm
2020
Highlights • This paper proposes a MCDM framework to support risk evaluation for maintenance activities. • The ANP is proposed to select the best maintenance strategy on the basis of real systems’ features. • The ELECTRE III is used to prioritise the main risks related to the interventions of the selected maintenance policy. • The proposed framework is applied to a core subsystem of a real-world marine salt manufacture firm.

Vinculación de la Cultura con los Objetivos de Desarrollo Sostenible: una necesidad cada vez mayor
2022
Los Objetivos de Desarrollo Sostenible (OSD), carecen de aspectos directamente vinculados con la cultura, que aparece de un modo transversal. Diversos documentos y autores proponen la ampliación de los ODS con uno más vinculado con la cultura, lo que se apoya en este trabajo, dado los aspectos relacionados que tienen desde el punto de vista ambiental, de la prosperidad, de los conocimientos y las competencias, de la inclusión y la participación.
importancia curricular de la Educación para la Ciudadanía en las escuelas de la Unión Europea
2022
Actualmente la sociedad se enfrenta a grandes desafíos a los que debe responder. Las Naciones Unidas aprobaron en 2015 la Agenda 2030 junto con los Objetivos de Desarrollo Sostenible con el fin de crear una ciudadanía capaz de dar respuesta a las necesidades y retos de la sociedad. Desde 1992 Europa sintió la necesidad crear una ciudadanía supranacional compuesta por todos los ciudadanos que forman la Unión Europea. La Educación para la Ciudadanía cumple con esta función y su implementación en los sistemas educativos de los países es muy diversa, dando como resultado diferentes ciudadanos.
