Plasma diagnostic tools for ECR ion sources : What can we learn from these experiments for the next generation sources
2019
International audience; The order-of-magnitude performance leaps of ECR ion sources over the past decades result from improvements to the magnetic plasma confinement, increases in the microwave heating frequency, and techniques to stabilize the plasma at high densities. Parallel to the technical development of the ion sources themselves, significant effort has been directed into the development of their plasma diagnostic tools. We review the recent results of Electron Cyclotron Resonance Ion Source (ECRIS) plasma diagnostics highlighting a number of selected examples of plasma density, electron energy distribution, and ion confinement time measurements, obtained mostly with the second-gener…
First Early Permian Paleomagnetic Pole for the Yili Block and its Implications for Late Paleozoic Postorogenic Kinematic Evolution of the SW Central …
2018
International audience; We conducted a paleomagnetic study on the Early Permian volcanic and sedimentary rocks, and the Neoproterozoic mafic dikes in the Yili Block, NW China. Magnetite and hematite were proven to be the principal magnetic remanence carriers. Demagnetizations revealed stable characteristic remanence magnetizations with a sole reversed magnetic polarity. The magnetic remanence of only the Early Permian strata turned out to be primary based on positive fold tests; meanwhile, the magnetic remanence age of the mafic dikes is ambiguous. Accordingly, the first Early Permian paleomagnetic pole for the Yili Block is calculated at λ = 81.5°N, φ = 256.5°E, N = 11, and A95 = 10.9°. Co…
Cambrian–Ordovician magmatism of the Ikh-Mongol Arc System exemplified by the Khantaishir Magmatic Complex (Lake Zone, south–central Mongolia)
2018
Abstract The Khantaishir Magmatic Complex (KMC) (south–central Mongolia) exposes a section of a magmatic system consisting of deep crustal, ultramafic cumulates (coarse-grained Amp gabbros and hornblendites; c. 0.35–0.5 GPa) to shallower crustal levels dominated by Amp–Bt tonalites ( c. 0.1–0.2 GPa). The magmatic rocks were emplaced during most of the Cambrian ( c. 538–495 Ma) and are mostly geochemically primitive (Mg# ~ 50), Na-rich and metaluminous. The (normal-) calc-alkaline signature and characteristic trace-element enrichment in hydrous-fluid mobile large-ion lithophile elements (LILE) relative to high-field strength elements (HFSE) suggest an origin within a magmatic arc. Multiple i…
La mafia sui Nebrodi e le frodi europee nel settore agro-zootecnico: l'attività di contrasto alla luce dei recenti interventi legislativi
2020
The book is the research thesis of Gabriele Minì for the grants that the Falcone Foundation and the Sicilian Regional Assembly award annually to young graduates of Sicilian universities. It deals with the abuse of public funding of agriculture in the Monti Nebrodi area of Sicily (province of Messina).After an accurate indication of the mechanisms for obtaining European funding to support agricultural and zootechnical activities, the book describes the forms of illegal exploitation of this by mafia organisations. The analysis also refers to case studies and describes the most significant events in this field. In particular, it highlights the importance of administrative prevention tools that…
Lucha contra la criminalidad organizada de tipo mafioso y el sistema penal italiano
2013
Despues l'indicacion de la falta inicial de consideración expresa del problema mafia en el código penal italiano y las primeras intervenciones de tipo extrapenal, se desarollian tres fases de l'accion antimafia: aquella vinculada a la ley de 1982; aquella siguente a la masacre de los magistrados Falcone y Borsellino en 1992; y aquella de resistematización de la ingente cantitad de normas del sistema especial en la materia, con el Código de Leyes Antimafia de 2011.

Misure di prevenzione antimafia e diritto del lavoro
2021
Il saggio affronta il tema delle interrelazioni tra misure di prevenzione e diritto del lavoro soffermandosi sul ruolo dell'amministratore giudiziario, sul licenziamento e sulla tutela del lavoratore nel mercato. The essay deals with the issue of interrelationships between prevention measures and labor law, focusing on the role of the judicial administrator, on dismissal and on the protection of the worker in the market.
Ca-rich carbonates associated with ultrabasic-ultramafic melts. Carbonatite or limestone xenoliths? A case study from the late Miocene Morron de Vill…
2016
The volcanic products of the late Miocene Morron de Villamayor volcano (Calatrava Volcanic Field, central Spain) are known for being one of the few outcrops of leucitites in the entire circum-Mediterranean area. These rocks are important because aragonite of mantle origin has been reported as inclusion in olivine macrocrysts. We use petrographic observations, mineral compositions, as well as oxygen and carbon isotope ratios coupled with experimental petrology to understand the origin of carbonate phase in these olivine-phyric rocks. Groundmass and macrocryst olivines range from δ18OVSMOW of +4.8‰, typical of mantle olivine values, to +7.4‰, indicating contamination by sedimentary carbonate.…
Il contrasto al caporalato grigio tra prevenzione e repressione
2019
Un recente decreto con cui il Tribunale di Milano, Sezione misure di prevenzione, ha disposto l’amministrazione giudiziaria ex art. 34 del Codice Antimafia nei confronti di una importante azienda multinazionale che opera nel settore della logistica, costituisce l’occasione per riflettere sugli strumenti a disposizione per contrastare lo sfruttamento del lavoro. L’articolo evidenzia come l’articolo 603 bis c.p. costituisca oggi uno strumento piuttosto versatile, capace di colpire le più varie forme di sfruttamento, anche al di là dei settori in cui le norme sul c.d. caporalato sono tradizionalmente state confinate, come l’agricoltura e l’edilizia. La norma, infatti, punisce anche condotte ch…
