No full textWhile waiting for the Census data for 2011, which will be used for a re-evaluation of the «social risk» due to volcanic eruptions of Vesuvius as a result of the combination of different variables, a re-evaluation of the volcanic risk per number of inhabitants was made on the basis of the Istat data of 2010 published in the Bilancio demografico e popolazione residente al 31 Dicembre. In fact, we need to do new research and update works in progress in order to have detailed information on the municipalities exposed to very high and high risk. For the purpose of providing backup to the strategic management of potential emergencies and defining a specific framework, we also provide an analysis of the recent demographic variations, taking into consideration the natural and
the migratory balance. This work also tries to provide a basis for future papers which intend to involve also the municipalities of the Phlegraean Fields (Campi Flegrei), according to comparable models, in order to draw up a classification of the Italian municipalities faced with the highest volcanic ris

No full textRole of Plastid Protein Phosphatase TAP38 in LHCII Dephosphorylation and Thylakoid Electron Flow
No full textShort-term changes in illumination elicit alterations in thylakoid protein phosphorylation and reorganization of the photosynthetic machinery. Phosphorylation of LHCII, the light-harvesting complex of photosystem II, facilitates its relocation to photosystem I and permits excitation energy redistribution between the photosystems (state transitions). The protein kinase STN7 is required for LHCII phosphorylation and state transitions in the flowering plant Arabidopsis thaliana. LHCII phosphorylation is reversible, but extensive efforts to identify the protein phosphatase(s) that dephosphorylate LHCII have been unsuccessful. Here, we show that the thylakoid-associated phosphatase TAP38 is required for LHCII dephosphorylation and for the transition from state 2 to state 1 in A. thaliana. In tap38 mutants, thylakoid electron flow is enhanced, resulting in more rapid growth under constant low-light regimes. TAP38 gene overexpression markedly decreases LHCII phosphorylation and inhibits state 1-->2 transition, thus mimicking the stn7 phenotype. Furthermore, the recombinant TAP38 protein is able, in an in vitro assay, to directly dephosphorylate LHCII. The dependence of LHCII dephosphorylation upon TAP38 dosage, together with the in vitro TAP38-mediated dephosphorylation of LHCII, suggests that TAP38 directly acts on LHCII. Although reversible phosphorylation of LHCII and state transitions are crucial for plant fitness under natural light conditions, LHCII hyperphosphorylation associated with an arrest of photosynthesis in state 2 due to inactivation of TAP38 improves photosynthetic performance and plant growth under state 2-favoring light conditions
La blessure qui sauve: la vulnérabilité entre crise et effondrement
No full textDans le cadre de la réflexion sur le sujet « Réapprendre le commun à l’épreuve de la vulnérabilité. La crise, un levier d’espérance ? », on pourrait dire que les trois termes choisis pour intituler ces pages (vulnérabilité, crise, effondrement) sont difficilement susceptibles de nous apprendre quelque chose de nouveau. La vulnérabilité, au moins celle qui concerne les humains, est un constat qui caractérise notre culture occidentale depuis ses origines. En effet, personne, pas même le héros, n’échappe à cette vulnérabilité, qui est à la fois possibilité et risque d’être blessé. La crise et l'effondrement sont eux aussi des événements qui reviennent fréquemment dans nos temps blessés. En contestant ce point de départ qui représente la vulgate communément admise à propos de la vulnérabilité et de la crise, l’article aborde la question qui concerne ces « concepts » en soulignant non seulement leurs aspects négatifs mais surtout ce qu’ils nous font réapprendre au sujet de l’humain et de ce qui permet à tous et toutes d’être en commun
