Electrochemistry-based chemotaxonomy in plants using the voltammetry of microparticles methodology
2015
A methodology for characterizing vegetal taxonomic groups using microextraction-assisted voltammetry of microparticles is described. It is based on recording the voltammetric response of microparticulate films of polyphenolic compounds of leaf extracts using different organic solvents. As a result, characteristic voltammetric profiles, tentatively defining an electrochemolomic response, are obtained. Bivariant and multivariant chemometric evaluation of the voltammetric responses of such films allows characterizing vegetal families. Analysis of voltammetric responses for a set of species of the Rosales order suggests that electrochemical data can be correlated with phylogenetic trees.
Genetic data of 10 X-STRs in a Spanish population sample
2007
In this work, we present population genetic data of 10 X-chromosome STRs (DXS8378, DXS9898, DXS8377, HPRTB, GATA172D05, DXS7423, DXS6809, DXS7132, DXS101 and DXS6789) obtained from sample of 145 unrelated female individuals belonging to Valencia (Spain), a region located in the east of the Iberian Peninsula. All the markers studied present high genetic diversities, similar to those previously reported in other European population samples. No deviations from Hardy-Weinberg equilibrium were observed, with the exception of DXS101 locus. Allele frequencies and parameters of forensic interest for each X-STR were calculated. High mean exclusion chance and power of discrimination values were obtai…
Inactivation and structural changes of polyphenol oxidase in quince ( Cydonia oblonga Miller) juice subjected to ultrasonic treatment
2020
Background Polyphenol oxidase (PPO) is considered a problem in the food industry because it starts browning reactions during fruit and vegetable processing. Ultrasonic treatment is a technology used to inactivate the enzyme; however, the mechanism behind PPO inactivation is still unclear. For this reason, the inactivation, aggregation, and structural changes in PPO from quince juice subjected to ultrasonic treatments were investigated. Different intensities and times of ultrasonic treatment were used. Changes in the activity, aggregation, conformation, and structure of PPO were investigated through different structural analyses. Results Compared to untreated juice, the PPO activity in treat…
Genetic Improvement of Sweet Chestnut in Sicily (Castanea sativa Mill.) by the Selection of Superior Autochthonous Genotypes
2010
In Sicily, the chestnut (Castanea sativa Mill.) grows in limited areas of the South eastern Mt. Etna volcano and of the Northern Mountains, namely Madonie and Nebrodi. In the Island, chestnut can be considered as a neglected species, because of the modest importance recognized to it for horticultural and forestry exploitation. Recently, the Sicilian regional government founded the 'Horticultural Forestry' project to promote the cultivation of chestnut as possible fruit tree for local city farmer markets, where typical products are usually sold. The project was developed in five steps, carried out during three years by the Dipartimento di Colture Arboree of Palermo University: identification…
Invasion history and genetic population structure of riverine macroinvertebrates.
2005
Summary Macroinvertebrate communities of large rivers have experienced dramatic species turnovers in the last decades, which still go on. The analysis of genetic population structure plays a central role in understanding and predicting these biological invasions. Two points of view are considered: the influence of the invasion history on the genetic structuring and the potential implications of genetic structure for future invasibility. Expectations about selectively neutral genetic variation in simple invasion models are compared to case studies of amphipods and Dreissena. The genetic patterns of one amphipod species of the Gammarus fossarum complex yield strong evidence for a stepwise reg…
Il concorso per il Rione Villarosa
2018
Negli anni del dopoguerra, l’interesse per le città crebbe. I concorsi di piano regolatore divengono mezzi per attuare questa trasformazione, in cui generatori sono le provvidenze amministrative e le combinazioni finanziarie. Anche a Palermo si tentò di diffondere una consapevolezza urbanistica, che si manifesta nella competizione per il Piano Regolatore di Palermo del 1939, e una serie di competizioni tra cui quella del Rione Villarosa. L’annuncio prevedeva infatti la creazione di una vera “città”, di fatto estranea alla natura del luogo. Tra i quindici progetti presentati, il bozzetto con lo pseudonimo “V. R. 112” formato da Aldo Della Rocca, Ignazio Guidi, Enrico Lenti e Giulio Sterbini …

Utility of island populations in re-introduction programmes--relationships between Arabian gazelles (Gazella arabica) from the Farasan Archipelago an…
2014
Understanding local adaptation and population differentiation is vital to the success of re-introduction initiatives. As other mammals living on islands, Arabian gazelles (G. arabica) show reduced body size on the Farasan archipelago, which we corroborated in this study through morphometric analyses of skulls. In the light of the steep population decline on the Arabian Peninsula – but stable population development on the archipelago – we tested the potential suitability of Farasan gazelles as a source for re-introductions on the mainland. We therefore investigated genetic differentiation between Farasan and mainland populations using eleven nuclear microsatellite loci and detected a distinc…

"L'Espagne c'est encore l'orient?" Pasado oriental y moral cristiana en Martínez de la Rosa
2013
A principios del siglo XIX, tanto absolutistas como liberales coincidían en situar los orígenes de España en la unión entre los primitivos hispanos y los visigodos, fundamentalmente a través de la conversión al cristianismo de los segundos. En las décadas siguientes, escritores, poetas, novelistas o historiadores románticos articularon desde una esfera pública cada vez más densa una narrativa de la nación liberal en la que la Edad Media ocupaba un papel destacado. Ahora bien, en un periodo tan esencial para la historia nacional como aquél, los autores españoles debían admitir que hispanorromanos y visigodos no eran sus únicos protagonistas, como advirtieron también los escritores foráneos. …
