    The article discusses the MS S. Pantaleo 8, a remarkable collection of Dante’s works now kept at the Biblioteca Nazionale Centrale in Rome. By investigating how the manuscript was prepared, and on the basis of the eight different writings of the scribes who copied the texts, as well as of the work of the three illuminators involved in the decoration of the book, the author suggests that the manuscript might have been copied around the mid-14th century either in eastern Tuscany or in Umbria

    Spazi bianchi e autografia. Riflessioni sulle ‘note’ di Petrarca

    Si prendono in considerazione alcuni brevi testi aggiunti da Francesco Petrarca in spazi rimasti inutilizzati all’interno di libri della sua biblioteca soprattutto in relazione al concetto di ‘traccia’, in questo modo giudicando in particolare l’estemporaneità della loro messa per iscritto

    XCDCC: Core Excitation in the Breakup of Exotic Nuclei

    Full text link
    The eXtended Continuum Discretized Coupled Channel (XCDCC) method is developed to treat reactions where core degrees of freedom play a role. The projectile is treated as a multi-configuration coupled channels system generated from a valence particle coupled to a deformed core which is allowed to excite. The coupled channels initial state breaks up into a coupled channels continuum which is discretized into bins, similarly to the original CDCC method. Core collective degrees of freedom are also included in the interaction of the core and the target, so that dynamical effects can occur during the reaction. We present results for the breakup of 17^{17}C=16^{16}C+n and 11^{11}Be=10^{10}Be+n on 9^{9}Be. Results show that the total cross section increases with core deformation. More importantly, the relative percentage of the various components of the initial state are modified during the reaction process through dynamical effects. This implies that comparing spectroscopic factors from structure calculations with experimental cross sections requires more detailed reaction models that go beyond the single particle model.Comment: 14 pages, revtex, submitted to Phys Rev

    TranScript è una rivista internazionale che si propone di essere un luogo di discussione sul tema della traduzione, con particolare attenzione ai secoli fra l’XI e il XV. Accogliamo con favore contributi sulla ‘traduzione’ dall’oralità alla scrittura, fra diverse tradizioni culturali, dal latino ai volgari e alle lingue moderne. TranScript is an international journal providing a forum for discussion on the theme of translation, with a special focus on the centuries spanning from the 11th to the 15th. We welcome contributions on the translation of cultures from orality to script, on the ‘translation’ among different cultural traditions, from Latin into vernaculars, and across modern languages

    Elastic scattering and breakup of 17^F at 10 MeV/nucleon

    Full text link
    Angular distributions of fluorine and oxygen produced from 170 MeV 17^F incident on 208^Pb were measured. The elastic scattering data are in good agreement with optical model calculations using a double-folding potential and parameters similar to those obtained from 16^O+208^Pb. A large yield of oxygen was observed near \theta_lab=36 deg. It is reproduced fairly well by a calculation of the (17^F,16^O) breakup, which is dominated by one-proton stripping reactions. The discrepancy between our previous coincidence measurement and theoretical predictions was resolved by including core absorption in the present calculation.Comment: 9 pages, 5 figure

    Plants and traditional knowledge: An ethnobotanical investigation on Monte Ortobene (Nuoro, Sardinia)

    <p>Abstract</p> <p>Background</p> <p>Most of the traditional knowledge about plants and their uses is fast disappearing as a consequence of socio-economic and land use changes. This trend is also occurring in areas that are historically exposed to very few external influences, such as Sardinia (Italy). From 2004 to 2005, an ethnobotanical investigation was carried out in the area of Monte Ortobene, a mountain located near Nuoro, in central Sardinia.</p> <p>Methods</p> <p>Data were collected by means of semi-structured interviews. All the records – defined as 'citations', i.e. a single use reported for a single botanical species by a single informant – were filed in a data base ('analytical table'), together with additional information: i.e. local names of plants, parts used, local frequencies, and habitats of plants, etc. In processing the data, plants and uses were grouped into general ('categories') and detailed ('secondary categories') typologies of use. Some synthetic indexes have also been used, such as Relative Frequency of Citation (RFC), Cultural Importance Index (CI), the Shannon-Wiener Index (H'), and Evenness Index (J).</p> <p>Results</p> <p>Seventy-two plants were cited by the informants as being traditionally used in the area. These 72 'ethnospecies' correspond to 99 botanical taxa (species or subspecies) belonging to 34 families. Three-hundred and one citations, 50 secondary categories of use, and 191 different uses were recorded, most of them concerning alimentary and medicinal plants.</p> <p>For the alimentary plants, 126 citations, 44 species, and 13 different uses were recorded, while for the medicinal plants, there were 106 citations, 40 species, and 12 uses. Few plants and uses were recorded for the remaining categories. Plants and uses for each category of use are discussed. Analyses of results include the relative abundance of botanical families, wild vs. cultivated species, habitats, frequency, parts of plant used, types of use, knowledge distribution, and the different cultural importance of the species in question.</p> <p>Conclusion</p> <p>The study provides examples of several interesting uses of plants in the community, which would seem to show that the custom of using wild plants is still alive in the Monte Ortobene area. However, many practices are no longer in use, and survive only as memories from the past in the minds of elderly people, and often only in one or just a few informants. This rapidly vanishing cultural diversity needs to be studied and documented before it disappears definitively.</p
