Catalytic valorisation of Chlorella sp. algae to obtain 5-Hydroxymethylfurfural in the presence of Nb2O5 or NbOPO4
2023
Microalgae are interesting biomass able to growth in not-arable lands, in wastewaters or seawaters. There are plenty of species of microalgae and several of them find application in various industrial sectors because they are source of several products in an integrated biorefinery view. In this work two acidic heterogeneous catalysts, namely Nb2O5 and NbOPO4 have been used. Both are commercial products provided by CBMM and they have been physico-chemically characterised. The isomerisation/dehydration reactions proceed through a tandem pathway involving the Lewis and Brønsted acid sites provided by the surface of the acidic solids giving rise to the isomerization of glucose to fructose, foll…
Influencia y sensibilidad de los mercados bursátiles europeos.
1999
Este trabajo analiza las relaciones entre los mercados bursátiles europeos y los de Nueva York y Tokio, durante el período 1988-1998. La no coincidencia de los horarios de negociación entre estos mercados determina los resultados de los análisis de correlación y de regresión con rendimientos diarios de los índices bursátiles de cada mercado de valores. Con el fin de solucionar éste y otros inconvenientes se contrasta el modelo propuesto por Peiró et al. (1998), que permite distinguir entre la capacidad de influir de un mercado sobre otro y la sensibilidad de ser influido por el resto de los mercados. Los resultados, en moneda local, indican que el mercado más influyente es Nueva York, mient…
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…
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…

Value added taxes on electronic commerce: Obstacles to the EU Commission’s approach
2000
While e-commerce is developing tremendously fast, domestic politics and legislation labour to keep up with the dynamics of the new technology. Among other things, fiscal law is a particularly explosive area. Here, the current proposal of the EU Commission is to apply the already existing value added tax to e-commerce. By doing so, the Commission hopes to prevent the massive threatened shortfall in tax revenue. How is this approach of the Commission to be judged? Are there any alternatives?
