First report of Diplodia africana on Grevillea robusta
2020
Branch cankers and dieback were observed on silky-oak trees (Grevillea robusta) along some streets of Palermo (Sicily, Italy). Fungi isolated from symptomatic branches were identified as Diplodia africana and D. seriata by morphological characters and phylogenetic analyses of combined ITS and translation elongation factor 1-α sequences. Pathogenicity was verified by inoculating twigs of 3-y-old silky-oak plants. This is the first report of D. africana on G. robusta and the first record of D. seriata on this host in the northern hemisphere.
The Mediterranean weedy vegetation and its origin
2007
An overview on the origin and evolutionary trends in the Mediterranean weedy vegetation is presented, with reference to the phytosociological units to which they are ascribed: Stellarietea mediae, Papaveretea rhoeadis, Oryzetea sativae. It is postulated that the “Neolithic revolution” was more likely a “Neolithic evolution”, i.e. the result of a process of selection and demographic growth that lasted for at least 10000 yrs, before leading to the domestication of plants and animals. During this very long time, wild crop relatives were simply growing together with the wild weed relatives, in their original milieu. At the beginning of agriculture, fields…
Antagonism of Bacillus subtilis strain AG1 against vine wood fungal pathogens
2009
Summary. Antagonistic substances produced by a Bacillus subtilis strain (AG1), which were previously found to slow down the growth of esca fungi in vitro, were produced in an artifi cial medium, isolated from the cell-free medium by precipitation and acidifi cation (to less than pH 2.5) and extracted from the precipitate with 96% ethanol. The crude extract employed in antibiotic assays confi rmed, in vitro, the antagonism of B. subtilis against Phaeoacremonium aleophilum and Phaeomoniella chlamydospora, and also showed antifungal activity toward Verticillium dahliae and Botryosphaeria rhodina.

Antinociceptive Effects of Turkish Endemic Eryngium kotschyi Boiss. Roots by Bioactivity Guided Fractionation
2010
Eryngium species (Apiaceae) are well known plants in ethnobotanical culture throughout world and also in Turkey. They are used as antitussive, diuretic as well as for analgesic and antiinflammatory purposes in traditional medicine. This study aimed to evaluate the antinociceptive activity of endemic Eryngium kotschyi Boiss. root extracts by bioguided fractionation. The antinociceptive activity of the extracts/fractions/compound was studied in mice using acetic acid induced writhing test and and hot plate test. The methanolic extract was sequentially partitioned with hexane, dichloromethane and water saturated n-butanol. Among the fractions, the n-BuOH fraction showed the most significant re…
Chemical Composition of the Essential Oil of Teucrium flavum ssp. flavum from Zakynthos, Greece
2012
Essential oil extracted from dried aerial parts of Teucrium flavum ssp. flavum harvested in Zakynthos, Greece, was analysed by gas phase chomatography (GC) and gas chomatography mass spectrometry (GC-MS). The main constituents were caryophyllene (13.5%), caryophyllene oxide (8.5%), 4-vinyl guaiacol (6.0%) and α- humulene (5.0%).

A tipper full of skinned limbs : fiction and the Northern Ireland Troubles
2013
This article discusses the potential of a fictional story, a novel, to challenge political narratives in a divided society. I will analyse three novels set during the ”Troubles” (1960s-1998) in Northern Ireland, looking at the ways in which each novel navigates the narrow space between Northern Irish unionism and nationalism, the two dominant narratives in Northern Ireland. I will read the novels politically, interpreting them as rhetorical narratives holding the power to challenge commonplace assumptions. I will apply the ideas put forward by James Phelan concerning the inherent rhetorical nature of narrative in fiction. I will also present Ann Rigney’s concept of cultural memory as an ana…
La place du français dans les programmes éducatifs plurilingues en Espagne
2014
Améliorer les compétences de communication en langues étrangères est devenu l’un des éléments clé de la politique éducative de l’Europe, en réponse à l’énorme défi de la mondialisation et à l’acquisition nécessaire de nouvelles compétences professionnelles. Les programmes plurilingues en langue étrangère ont ainsi acquis une place de plus en plus importante dans notre réalité éducative. Cet article présente une réflexion sur la situation actuelle de ces programmes et montre les obstacles à franchir pour l’enseignement du français comme deuxième langue étrangère avec l’arrivée de la LOMCE (Loi Organique pour l’Amélioration de la Qualité de l’Éducation).
