Get PDFRegeneration and selection of quince BA29 (Cydonia oblonga Mill.)somaclones tolerant to lime-induced chlorosis
No full textQuince is the most used rootstock in Italian pear orchards, but due to the its high susceptibility to calcareous soils it induces widespread chlorosis problems on the grafted pear cultivars. Until recently, the common breeding techniques have not allowed the simple production of tolerant quince selections. Thus, somaclonal variation, and the large genetic variability brought about during the in vitro processes, might be a suitable tool to obtain genotypes with better agronomic characteristics. The aim of the present research was to induce in vitro regeneration of quince shoots under Fe-limiting conditions from leaves (of quince clone ‘BA29’), and subsequently to evaluate their tolerance to lime-induced chlorosis. Leaves of explants were placed onto MS medium supplemented with TDZ and NAA, and the selective pressure conditions were obtained by reducing the normal MS iron content and/or by adding different concentrations of potassium bicarbonate (KHCO3). Selective conditions decreased both the percentage of shoot-forming leaves and the mean number of shoots per organogenetic leaf, as the iron content was reduced and/or the KHCO3 content was increased. A discrete number of putative somaclones, showing a range of severe chlorosis symptoms compared to a wild type clone, were chosen by visual assessments, and further tests were conducted under reduced amounts of Fe and the presence of 1.0 mM of KHCO3 conditions. DB-34 somaclone seemed to be the most promising one, because its chlorophyll content did not reduce as happened in the other somaclones and with the wild type clone. Stress conditions affected only the Fe2+ content of the DB-43 somaclone, even if under normal conditions the Fe2+ content was much higher than with all the other accessions. On the contrary, the medium acidification capacity of all somaclones was influenced similarly by treatments. A preliminary in vivo test confirmed these results. Moreover, preliminary RAPDs analyses disclosed polymorphism within the somaclones and among them and the wt clone. The sequence of chloroplastic protein D1, codified by the psbA gene, was determined in quince ‘BA29’ and pear ‘Conference’ to predict its hypothetical functions. Sequences showed differences in length and in amino acidic composition. In quince, the main modification is located in the ‘191’ position where tyrosine substitutes histidine, causing a loss of one of the iron-binding sites

Non voler “essere lì” : Sul valore documentale delle immagini panoramiche nel processo per gli attentati del 13 novembre 2015 a Parigi
No full textThe paper scrutinizes documentary immersive images, portraying environments de-
picting historical events and presented as authentic representations. It explores the discur-
sive placement of trust in such images, specifically examining whether a 360–degree view in
videos or images contributes to perceived content trustworthiness. Environmental images,
while promising medial transparency by minimizing framing impact, present a “substantial
inconsistency” as their mechanical objectivity tends to prioritize technical device neutrality
over human subjectivity. The study focuses on visual traces from the trial of the November
13, 2015 attacks (also known with the acronym V13), housed in the French Archives na-
tionales. The panoramic dimension of these images, meant as an investigative tool, facili-
tates spatial exploration of the crime scenes, whilst offering critical insights on the role of
immersive imagery as evidentiary technologies. Analysis of intentional and unintentional
semiotic processes, like ‘censoring’ bodies and corps, allows an understanding of the immer-
sive dimension’s role within a legal and ‘monumental’ framework. The paper advocates for
integrating the study of immersive images into a historically and socially situated framework
in the context of the naturalization of immersive devices in contemporary society
Gli obblighi positivi degli Stati in materia di investimenti stranieri e la privatizzazione del "nuovo" diritto umano all'acqua
No full textIl presente contributo analizza l'interazione tra la disciplina degli investimenti esteri e la tutela dei diritti umani, con particolare riferimento al "nuovo" diritto umano all'acqua, così come riconosciuto dall'Assemblea generale delle Nazioni Unite nel 2010. L'analisi è svolta alla luce della prassi giurisprudenziale del ICSID

Get PDFItalian wine tourism and the web: A necessary wedding
No full textAbstractDirector and founder of “Fattoria del Colle” agritourism and “Casato Prime Donne” winery (Montalcino), Donatella Cinelli Colombini has published books about wine business and tourism and received numerous awards for her entrepreneurial activities, such as “Best Italian producer” in 2003 and “Vinitaly International Award” in 2012; moreover, she was Tourism Councilor for the Municipality of Siena from 2001 to 2011. In this business article, the author examines the Italian wine tourism market, which has a huge potential but it is still not fully exploited, supplying suggestions for possible effective strategies to improve its success
The gabbro and serpentinized peridotite of Bonassola (Bracco-Levanto ophiolte, Italy) - An extremely low natural radiation area to improve in situ gamma spectrometry
Get PDFOutcrops of dunite, serpentinized peridotite and clinopyroxene-rich coarse gabbro around Bonassola (Bracco-Levanto ophiolite, NW Italy) have been analyzed
for natural radionuclides using γ-spectrometry. The very low activity concentrations of natural radionuclides in the dunite outcrop (< 9.0 Bq kg-1 226Ra;
< 3.5 Bq kg-1 228Ac and < 25 Bq kg-1 40K) indicate that this site is characterized by a very low natural radiation for both cosmic (being at sea level) and terrestrial
contributions. Before starting a field radiometric survey it is important to assess the local background, i.e. the g radiation that does not originate from
rock, in order to correct the measurements for the local background. Contrary to the general practice regarding the background radiation in γ-spectrometry
measurements, the investigated mafic-ultramafic outcrops has been used to estimate the detection limits for in situ measurement of 238U, 232Th and 40K using
sodium iodine (NaI) scintillator detectors. These results have proved useful to quantify the minimum detectable amount of activity (MDA) of 238U, 232Th and
40K for the NaI detector; the MDA points at sub ppm levels for 238U and 232Th and 0.01 wt% K2O.
This study also permits to assess the radiological risk of dimension stones that are petrographically similar to the serpentinized ultramafics occurring in the
Bracco-Levanto ofiolite. The comparison of the activity concentration index I, defined by the EU Basic Safety Standards Directive and depending on the activity
concentrations of 226Ra, 232Th and 40K, with other stones used as building material, indicates that the Bonassola mafic-ultramafic rocks provide a negligible
contribution to the indoor gamma radiation dose
Municipal waste management: A complex network approach with an application to Italy
No full textThe paper contributes to the debate concerning the management of municipal solid waste by providing an analysis of two key aspects of waste management - namely, waste separation and dispatch to treatment plants. Our analysis aims at detecting the extent to which actual behavior in (close-by) municipalities is similar with respect to those two aspects. To pursue our scope, a complex network approach is followed. In particular, we conceptualize, explore and compare two networks, whose nodes are the municipalities, while weights synthesize in one network the percentage of sorted waste that is collected at a municipal level, and in the other one the distance from the waste processing plants used by each municipality. The theoretical network models are implemented through an empirical study based on a high quality dataset referred to Italian municipalities. In this regard, the detection of communities of municipalities and their geospatial contextualization are introduced as devices for a complete description of current practices of municipal waste separation and transfers in Italy
