Photocatalytic CO 2 Valorization by Using Ti O2 , ZrO2 and Graphitic Based Semiconductors
2018
In this century, a broad scientific interest has been devoted to fulfill sustainable industrial processes and climatic change remediation. In this prospective, various green technologies have been studied to valorize CO 2• The aim of this research is the CO 2 reduction in presence of water by using the photocatalytic technology with nanomaterials as the photocatalysts. The present work overviews the main outcomes obtained by using graphitic and oxide based photocatalysts both in gas/solid and liquid/solid batch reactors under simulated solar light. In all gas/solid regime tests the major products detected were methane, carbon monoxide, and acetaldehyde.
Investigación inter e intra-variable del valor percibido: un modelo causal de segundo orden y satisfacción cognitiva y afectiva
2017
El valor percibido es axiomática y epistemológicamente clave para el Marketing. Su investigación es rica y profunda respecto a su dimensionalidad (análisis intra-variable) y a su relación con satisfacción y lealtad (inter-variable). Como contribución a la abundante literatura sobre medición del valor percibido en servicios turísticos, este trabajo propone un modelo causal que abarca las perspectivas inter e intra-variable, y propone el valor percibido como segundo orden y la cadena valor-satisfacción-lealtad, con una bifurcación de la satisfacción en afectiva y cognitiva. El modelo es testado con PLS sobre una muestra de 340 huéspedes de hotel en la Comunidad Valenciana, hallando contribuci…
Démocratisation de l'enseignement supérieur et emprise des parcours
2014
This article looks at how the organization of the education system and the pathways leading to higher education enable social mobility or on the contrary the reproduction of inequalities. We thus compare three countries: France, Switzerland, and Canada. The results using panel data in these three countries show two different situations. The more higher education is valued rather than vocational training, the more inequalities tend to increase. The competition is such that it is the youth with a privileged social background who benefit more from its expansion. On the other hand, when the vocational education and training is more valued, inequalities in higher education could tend to be more …
Esistenza, dialettica, valore nel pensiero di Giuseppe Cantillo
2021
The article aims to place Giuseppe Cantillo’s studies collected in his latest two books, focused respectively on Hegel and dialectics and Jaspers and existence, in the overall research itinerary of the Italian philosopher. The paper seeks to highlight the coherence and conceptual openness of Cantillo’s investigation of history, the human being’s existential conditions, as well as of its theological implications. This meditation is characterized, on the one hand, by the anchorage to the transcendental dimension of thought and, on the other hand, by the adherence to the concreteness of history. These two aspects are linked by the sphere of values, which shed light on the finalistic and person…

Il recupero e la messa in valore della Judería di Segovia
2013
The Spanish town of Segovia, World Heritage Site, launched a process of valorisation of its historical centre, supporting conservation and musealisation of monuments as well as encouraging recovery of private houses, particularly in the Judería District. Here, thanks to the Program Área de Rehabilitación de Centro Histórico (ARCH), Segovians were encouraged to go back to the historical center. The Oficina Técnica de Rehabilitación coordinated activities and funding, promoted the participation of owners and entrepreneurs, sensitised citizens on the issues of cultural heritage. The results obtained in the Judería District were so good that ARCH has been adopting in the next district las Canon…

Valorisation of industrial iron oxide waste to produce magnetic barium hexaferrite
2016
Barium M-type hexagonal ferrite (BaM, BaFe12O19) is an immensely important magnetic material, which we have successfully made from the simple valorisation of Fe-rich industrial waste from steel wire drawing, with addition of BaCO3 and heating in air to 1000 degrees C. The optimum ratio of Fe. Ba (producing 86 wt% BaM) was found to be 11: 1 (non-stoichiometric), and secondary phases of alpha-Fe2O3 (non-magnetic) and ZnFe2O4 (poorly antiferromagnetic) were always present. This material consisted of small submicron platelets. A hard magnetic ferrite was produced with Ms=48.6 A m(2) kg(-1) and H-c=211.5 kA m(-1). The highest density was achieved by sintering samples with Fe: Ba ratios of 11: 1 …
