Rimboschimenti e uso energetico della biomassa forestale nei Monti Sicani (Sicilia occidentale)
2014
Nell’ottica di un utilizzo energetico sostenibile delle biomasse provenienti dalle utilizzazioni forestali è di fondamentale importanza conoscere la consistenza e le esigenze ecologiche delle formazioni forestali che caratterizzano il territorio regionale. In questo lavoro è illustrato uno studio sulla consistenza e sulle caratteristiche ecologiche e strutturali dei rimboschimenti presenti nel territorio dei Monti Sicani. L’analisi è finalizzata a quantificare la disponibilità di biomassa forestale residuale ottenibile dalla gestione sostenibile di tali popolamenti e valutare il possibile uso energetico. L’analisi è stata condotta sulla base dei dati disponibili per l’area di studio presso …
Effect of macro and micro nutrients addition during anaerobic mono-digestion of grass silage in leach-bed reactors
2019
The effect of macro- (NH4Cl) (set I) and micro-nutrients (Fe, Ni, Co and Mo) (set II) addition on chemical oxygen demand (COD) solubilisation during anaerobic mono-digestion of grass silage was investigated in two sets of leach bed reactor experiments at 35°C. Results showed that addition of NH4Cl and micro-nutrients improved COD solubilisation by 18% (0.56 g SCOD g−1 volatile solids) and 7% (0.45 g SCOD g−1 VS), respectively than control. About 20–50% of the added micro-nutrients were bioavailable in the produced leachates, while the rest (50–80%) were adsorbed onto the grass silage. Results of biological methane potential assays showed that, specific methane yields of grass silage were im…
El debate sobre Europa en Twitter. Discursos y estrategias de los candidatos de las elecciones al Parlamento Europeo de 2014 en España.
2015
En este artículo se realiza un análisis de la campaña electoral desarrollada en las redes sociales, y en concreto Twitter, por parte de los cabezas de lista de ocho formaciones políticas españolas en las Elecciones al Parlamento Europeo de mayo de 2014. El objetivo fundamental del análisis es comprobar en qué medida el discurso de los candidatos se ciñe a temáticas de alcance europeo o, por el contrario, encuadra su campaña en relación con cuestiones de ámbito nacional. Para ello, el artículo desarrolla tres perspectivas metodológicas complementarias: un análisis cuantitativo de la actividad de los candidatos en Twitter; un análisis de contenido de los mensajes publicados por los candidatos…
Which has more influence on perception of pseudo-therapies: the media’s information, friends or acquaintances opinion, or educational background?
2019
This study analyses the discourses of Education and Journalism students in order to understand their perception of complementary and alternative therapies. Likewise, to know if educational background or friends or acquaintances opinion has a more considerable influence on their knowledge and use of these socially controversial techniques than the media. This study uses qualitative research methods based upon 12 discussion groups with 102 participants. Once transcriptions were completed, discourse analysis was conducted using linguistic corpus software (T-LAB. 9.1.). In the design of the research, these students were selected for their social involvement in their future careers, such as when…

Characterization of heat-labile toxin-subunit B from Escherichia coli by liquid chromatography-electrospray ionization-mass spectrometry and matrix-a…
2012
The possibilities of characterizing the heat-labile enterotoxin (LT) of enterotoxigenic Escherichia coli (ETEC) by liquid chromatography electrospray mass spectrometry (LC/ESI-MS) and matrix-assisted laser desorption with time-of-flight mass spectrometry (MALDI-TOF-MS) were investigated. The B subunit from recombinant E. coli (expression in Pichia pastoris) can be detected by LC/ESI-MS expressed in P. pastoris and the charge envelope signals can be observed; LC/ESI-MS and MALDI-TOF-MS analysis allowed the acquisition of labile toxin subunit B (LTB) molecular weight and preliminary structural characterization of LTB toxin. MALDI-TOF analysis after reduction and alkylation of the protein evid…

New construction of algebro-geometric solutions to the Camassa-Holm equation and their numerical evaluation
2011
An independent derivation of solutions to the Camassa-Holm equation in terms of multi-dimensional theta functions is presented using an approach based on Fay's identities. Reality and smoothness conditions are studied for these solutions from the point of view of the topology of the underlying real hyperelliptic surface. The solutions are studied numerically for concrete examples, also in the limit where the surface degenerates to the Riemann sphere, and where solitons and cuspons appear.
'Where Have I Heard It?' Assessing the Recall of Traffic Safety Campaigns in the Dominican Republic
2021
Although traffic crashes are the eighth leading cause of death in the world, and are linked to vehicle and infrastructure-related factors, crash-related fatality rates are much higher in lowincome countries. Particularly, the Dominican Republic is the country with the highest accident rate in the whole American continent. Therefore, in the past few years, public agencies have been developing different measures aimed at reducing traffic fatalities, including road safety campaigns. The aim of the present study was to assess the recalling of such campaigns among the Dominican population, which may serve as an additional indicator to evaluate their effectiveness in this and other countries of t…
