Influence des facteurs naturels sur la maturation du raisin, en 1979, à Pomerol et Saint-Emilion
1981
<p style="text-align: justify;">Les vignobles de Pomerol et Saint-Emilion sont implantés sur des sols dérivant de roches-mères variées; ils produisent des vins de haute qualité mais différents suivant leur origine géologique.</p><p style="text-align: justify;">Dans les meilleurs crus, nous avons pu vérifier que les variations mésoclimatiques sont très faibles et ont peu d'influence sur les caractères des vins. Par contre, en 1979, une relation a été mise en évidence entre les conditions de l'alimentation en eau de la vigne (étroitement liées aux propriétés physiques des sols) et la constitution des raisins à maturité (<em>V. vinifera</em> var. Merlot noir).<…
The alien vascular flora of Stromboli and Vulcano (Aeolian Islands, Italy)
2021
The updated censuses of the alien flora of the islands of Stromboli and Vulcano, Aeolian Islands in the Central Tyrrhenian Sea, are presented here. They currently consist of 40 and 57 specific and subspecific taxa respectively. As many as 16 and 18 taxa respectively are new in comparison with the last censuses in 2016. Mesembryanthemum × vascosilvae, commonly cultivated in both islands, is reported for the first time as naturalized alien to Italy. Passiflora incarnata from Stromboli and Pelargonium graveolens from Vulcano are reported for the first time as casual aliens to Sicily. The evolution over time of these florulas, as inferred from the main floristic works published on these islands…
THE CLASS QUERCO-FAGETEA SYLVATICAE IN SICILY: AN EXAMPLE OF BOREO-TEMPERATE VEGETATION IN THE CENTRAL MEDITERRANEAN REGION
2012
A syntaxonomical revision of the class Querco-Fagetea sylvaticae in Sicily, based on literature data and unpublished relevés, is presented. This class groups the mesophilous woods characterized by the dominance of deciduous trees (e.g. Fagus sylvatica, Quercus sp. pl., Acer sp. pl.), and more rarely by conifers (Taxus baccata, Pinus nigra subsp. calabrica), as well as by other broadleaved trees, such as Betula aetnensis, Populus tremula, Castanea sativa. In Sicily, these woody communities are widespread in the northern and north-eastern districts of the island, chiefly on the highest peaks (Madonie, Nebrodi, Peloritani, and Etna). This class is represented in Sicily by two, both flor…
Estratègies discursives iròniques en la narrativa catalana actual: l'autoconsciència textual
2010
A partir de textos de Jesús Moncada, Quim Monzó, Carme Riera, Ramon Solsona i Sergi Pàmies, l'article analitza l'existència en la narrativa breu catalana actual d'una tendència que es caracteritza per l'ús dels recursos de la metaficció, adaptats als interessos literaris i a l'estil de cada autor però amb una orientación general compartida. Es tracta d'una tendència de clar signe antirealista i amb plena consciència de textualitat que fa explícits els mecanismes de la ficció; una modalitat de discurs irònic que s'interroga sobre les possibilitats i els límits de representació del real i, en definitiva, sobre allò que entenem per realitat. Departing from some texts by Jesús Moncada, Quim Mon…
Dust Production and Particle Acceleration in Supernova 1987A Revealed with ALMA
2013
Supernova (SN) explosions are crucial engines driving the evolution of galaxies by shock heating gas, increasing the metallicity, creating dust, and accelerating energetic particles. In 2012 we used the Atacama Large Millimeter/Submillimeter Array to observe SN 1987A, one of the best-observed supernovae since the invention of the telescope. We present spatially resolved images at 450um, 870um, 1.4mm, and 2.8mm, an important transition wavelength range. Longer wavelength emission is dominated by synchrotron radiation from shock-accelerated particles, shorter wavelengths by emission from the largest mass of dust measured in a supernova remnant (>0.2Msun). For the first time we show unambig…
Le varianti d’autore in "Asterusher" di Michele Mari
2021
Nel 2019 Michele Mari pubblica una seconda edizione del fototesto Asterusher. Autobiografia per feticci, con l’aggiunta di sedici pagine. La riscrittura diventa innanzitutto una ricomposizione grafica e una nuova disposizione delle pagine, la cui sequenza si dimostra un ampliamento, grazie ad alcune necessarie integrazioni, oppure un’intensificazione di nuclei tematici, sviluppati soprattutto a partire dalle relazioni genitoriali che erano state al centro di Leggenda privata. Il contributo propone lo studio di alcune varianti d’autore e delle loro funzioni nell’archivio fototestuale autobiografico degli oggetti pregnanti di Michele Mari. In 2019 Michele Mari publishes a second edition of th…
First phenotypic description of Fasciola hepatica/Fasciola gigantica intermediate forms from the human endemic area of the Nile Delta, Egypt.
2007
Fasciola gigantica is the main fasciolid species in Africa; however, F. hepatica and F. gigantica overlap in some countries. Egypt deserves mentioning because of the emerging situation of human fascioliasis in the Nile Delta area. The morphometric characteristics of fasciolid adults infecting the main livestock species present in the Nile Delta human endemic area are analyzed through a computer image analysis system (CIAS) on the basis of standardized measurements known to be useful for the differentiation of both fasciolid species. This is the first time that such a study is performed in an African country and, therefore, the results are compared to (i) F. hepatica (European Mediterranean …
Ventilator-associated Pneumonia and MRSA ST398, Italy
2010
To the Editor: Methicillin-resistant Staphylococcus aureus (MRSA) sequence type (ST)398 has become increasingly common in livestock, particularly pigs, in some countries in Europe, such as Spain and Germany (1). In Italy, prevalences as high as 14% and 21.6% in pig-breeding facilities and meat-processing sites, respectively, have been recently reported (1). Possible association of MRSA in animals with infection in humans has been investigated. One study showed a strong relationship between contact with pigs or calves and carriage by persons having direct contact with animals and families of persons who handle animals (2). Moreover, an MRSA prevalence >11.9% has been described by de Boer et …
Leaf water potential meaning of different modalities of measurements
2004
<p style="text-align: justify;">An experiment on Syrah in the Ecotron design of the AGRO Montpellier/INRA campus vineyard, with the control of different water regimes, allowed to test the physiological meaning and the field of application of different modalities of leaf water potential measurements : predawn and daily potential for leaves in a normal micro-environment (which keep all of their interest and generality), « stem » potential (which must be called differently and reserved to particular conditions) for shadow enveloped leaves. Field observations on Syrah and Merlot confirm the interest of some methods.</p>
Investigation on the pollen morphology of traditional cultivars of Prunus species in Sicily
2012
In this study pollen grains of 13 cultivars and 3 rootstocks belonging to 5 species (<em>P. armeniaca</em>, <em>P. domestica</em>, <em>P. dulcis</em>, <em>P. persica</em>, <em>P. avium</em>) of the genus <em>Prunus </em>collected from North-East Sicily were examined for the micromorphological characterization through the scanning electron microscopy (SEM). The length of polar axis (<em>P</em>) and the equatorial diameter (<em>E</em>) of grain, <em>P/E </em>ratio, the length of colpi (<em>C</em>), diameter of perforations (<em>DP</em>) and the number of perforat…
