Totalitarismo y dictadura: Arendt para leer la historia reciente de Chile
2017
***Totalitarianism and dictatorship: Arendt to read chilean’s recent history***This article seeks to expose and discuss the pertinence or inpertinence of two key concepts in the thinking of Hannah Arendt, to describe and understand fundamental processes of Chile's recent history: In one hand, 'totalitarianism' as a regime founded on Terror to refer to the dictatorship of Augusto Pinochet that took place between 1973 and 1989. In other hand 'labor society' as a form of post-totalitarian society, oriented to labor and consumption, to describe one of the central aspects of the neoliberal society that the Chilean dictatorship installs. Este artículo busca exponer y discutir la pertinencia o la …
INEQUALITIES AND TOURISM CONSUMPTION BEHAVIOUR: A MIXTURE MODEL ANALYSIS
2015
The criticism of income as a measure of well-being and trends in living standards is well known and recently scholars have been involved in defining measures to better assess material well-being and differences in living standards. Recent evidence shows that individuals improve their well-being significantly if they are able to spend on higher-order goods and services like tourism and leisure activities. In the light of that, our study proposes to explore differences in living standards in Italy by analysing the distribution of tourism expenditure. For this aim, Mixtures of Regression Models were used in order to investigate whether there is an unobserved heterogeneity in tourism consumptio…
Trace element behavior in the fluidized bed gasification of solid recovered fuels
2013
Gasification of biomass and recycled fuels is of particular interest for the efficient production of power and heat. Trace elements present as impurities in the product gas should be removed very efficiently. The objective of this work has been to develop and test thermodynamic models for the reactions of trace elements with chlorine and sulfur in the gasification processes of recycled fuels. In particular, the chemical reactions of trace elements with main thermochemical conversion products, main ash components, and bed and sorbent material are implemented into the model. The possibilities of gas cleaning devices in condensing and removing the trace element compounds are studied by establi…
Energy efficiency and CO2 emissions of port container terminal equipment: Evidence from the Port of Valencia
2019
Abstract Energy efficiency has emerged as a key point in port industry because of different factors such as the adoption of stronger environmental regulations and the increasing pressure of the local community on the surrounding ports. As gathering operational data from port terminals can be difficult due to privacy, studies on emissions and energy efficiency of these terminals are scarce. The following research provides key information about the real energy consumption and CO2 emissions of one of the most relevant container terminals in the Mediterranean area, located in Valencia, Spain. The results show that yard terminal tractors and rubber tyred gantry cranes (RTGs) are the main emissio…
“Rationally Local”: Consumer Participation in Alternative Food Chains
2015
Why are consumers increasingly participating in alternative food chains to co-produce and distribute foods with farmers? In this paper, values and food-related lifestyles, as well as transaction costs and socio-demographics, are used to analyze consumer participation in alternative food chains in Italy. Using a simultaneous system of equations, a model with instrumental variables is implemented to measure the relationships between values and food-related lifestyles, and between the latter and participation in an alternative food chain. Our results show that Italian participants in alternative food chains have the profile of rational shoppers who typically look at price and taste criteria. A…
Preamble Sampling MAC Protocol for Low Power Wireless Sensor Networks with IEEE 802.15.4 Transceivers
2006
In this paper a preamble sampling MAC protocol for low power wireless sensor networks is proposed. The article describes the implementation of the protocol using network nodes equipped with the Chipcon CC2420 802.15.4 transceiver. The power consumption of the transceiver has been measured and the MAC protocol has been adapted to the transceiver properties. The results show the trade-off between power consumption and transmission delay for this algorithm during the communication process.
Smart vs conventional motorways: environmental impact assessment under realistic traffic conditions
2020
Abstract This research aims at assessing the environmental impacts exerted by a smart motorway compared to those of a traditional motorway. The study has global policy implications: it takes into account the impacts due to the construction and maintenance of the infrastructure and the environmental effects produced by the traffic emissions, taking into account smart technologies and truck platooning regulation. Through a classical LCA approach, 1 km-long smart motorway with 2 m-high embankment was assumed as the functional unit for the analysis. A realistic traffic condition has been considered. A comparison between environmental effects produced by the use of virgin material and by Reclaim…
Application of textile fibres from tire recycling in asphalt mixtures
2022
The tire rubber obtained from end-of-life car and truck tires has been successfully recycled, among other applications, in the asphalt industry by providing a mean to get asphalt mixtures with superior performance. Textile fibres are another component derived from tire recycling typically disposed of in landfills or used in energetic valorisation. This paper wants to re-ignite interest in this secondary product by evaluating its use as a valuable resource in asphalt mixtures. Indirect tensile tests, dynamic modulus, fatigue resistance, and permanent deformation tests were performed on a series of AC14 asphalt mixtures manufactured with two binders, namely 50/70 and 35/50 pen, using several …
Tourist consumption behaviour in a sun and beach Mediterranean mature destination and its implications for local development
2015
El comercio de buena parte de los destinos maduros de sol y playa, a lo largo de la orilla norte del mar Mediterráneo, ha tenido que afrontar varios años de rendimientos decrecientes a causa de la crisis económica que han sufrido los principales mercados de origen (nacional e internacional), y a la competencia de nuevas formas y destinos turísticos. En la mayoría de los casos, se trata de núcleos urbanos con un comercio estacional de proximidad que solo se activa durante la breve temporada alta. El resto del comercio urbano apenas se beneficia del consumo de un turismo que permanece recluido en el espacio de playa. En este trabajo se presentan los resultados de un análisis empírico de los h…
Indirect oxidation of the antitumor agent procarbazine by tyrosinase—Possible application in designing anti-melanoma prodrugs
2008
The interaction of tyrosinase with the anticancer drug procarbazine has been investigated. In the presence of the enzyme alone no oxidation of this dialkylhydrazine above the background level was observed. However, when phenolic substrates (4-tert-butylcatechol or N-acetyl-l-tyrosine) were included in the reaction mixture, procarbazine was rapidly degraded. Oxygen consumption measurements showed that in a mixture both the phenolic substrate and the drug were oxidized. The major product of procarbazine degradation was isolated and identified as azoprocarbazine, the first active metabolite of this drug detected in previous in vivo and in vitro studies. This indirect oxidation of the hydrazine…
