A growing interest of the scientific community towards multidisciplinary applications of laser-driven beams has led to the development of several projects aiming to demonstrate the possible use of ...these beams for therapeutic purposes. Nevertheless, laser-accelerated particles differ from the conventional beams typically used for multiscipilinary and medical applications, due to the wide energy spread, the angular divergence and the extremely intense pulses. The peculiarities of optically accelerated beams led to develop new strategies and advanced techniques for transport, diagnostics and dosimetry of the accelerated particles. In this framework, the realization of the ELIMED (ELI-Beamlines MEDical and multidisciplinary applications) beamline, developed by INFN-LNS (Catania, Italy) and that will be installed in 2017 as a part of the ELIMAIA beamline at the ELI-Beamlines (Extreme Light Infrastructure Beamlines) facility in Prague, has the aim to investigate the feasibility of using laser-driven ion beams for multidisciplinary applications. In this contribution, an overview of the beamline along with a detailed description of the main transport elements as well as the detectors composing the final section of the beamline will be presented.
Acoustic noise levels were measured in the Gulf of Catania (Ionian Sea) from July 2012 to May 2013 by a low frequency (<1000Hz) hydrophone, installed on board the NEMO-SN1 multidisciplinary ...observatory. NEMO-SN1 is a cabled node of EMSO-ERIC, which was deployed at a water depth of 2100m, 25km off Catania. The study area is characterized by the proximity of mid-size harbors and shipping lanes. Measured noise levels were correlated with the passage of ships tracked with a dedicated AIS antenna. Noise power was measured in the frequency range between 10Hz and 1000Hz. Experimental data were compared with the results of a fast numerical model based on AIS data to evaluate the contribution of shipping noise in six consecutive 1/3 octave frequency bands, including the 1/3 octave frequency bands centered at 63Hz and 125Hz, indicated by the Marine Strategy Framework Directive (2008/56/EC).

The subject of this paper is the study of the pre-Linnaean herbarium of Paolo Boccone (1633-1704) which is kept in Leiden (the Netherlands) and its connections with two works of the same author: the ...imprinted herbarium kept in Paris in the Bibliothèques Interuniversitaires de Médecine and the printed volume "Icones et Descriptiones" of 1674. By means of the comparative analysis of the three works we have verified the existence of numerous similarities (even a complete overlap) between the samples of the Leiden herbarium (some with visible traces of ink), the imprints of the Paris herbarium and the figures of "Icones et Descriptiones". The drawings to be found in this work, thanks to the realistic fidelity that distinguishes them, have been used by various authors until quite recent times for the description of new taxa. This shows the importance and the usefulness of the herbarium in question for the processes of typification. The taxonomic identification of the specimens (121 angiosperms and 1 alga) allowed us to designate the lectotype and the epitype of Daucus gingidium subsp. polygamus (Gouan) Onno and of Daucus carota subsp. commutatus (Paol.) Thell.
A study of an anonymous pre-Linnaean herbarium, currently kept in the "Civica and A. Ursino Recupero" joint library of Catania (Italy) has been carried out. The volume examined consists of 86 ...unnumbered pages. It is made up of 121 specimens (currently four samples are missing), all belonging to Angiosperms. The samples are not all in good condition; however, it was possible to determine most of them (86%) up to species level. Most of the taxa are made up of alien plants (20.62%) of African and American origin. A series of concordant clues leads us to conjecture that the herbarium was produced by Antonio Bonanno (a pupil of Francesco Cupani) on the orders of the Prince of Cattolica, and/or some of his collaborators (or successors). The report of exchanges of plants with William Sherard, the particular composition of the collection and the documented knowledge of the international literature allow us to place the herbarium in the context of the intense scientific activity that took place in Sicily even after the deaths of Paolo Boccone and Cupani, two important pre-Linnaean Sicilian botanists.
Abstract
A project for an upgrade of the Superconducting Cyclotron is underway at INFN-LNS. One of the goals of this project is the production of RIBs (Radioactive Ion Beams) of high intensity. To ...reach this purpose, a dedicated facility consisting of a new fragment separator FRAISE (FRAgment In-flight SEparator) is ongoing, exploiting primary beams with a power up to ≈ 2-3 kW. The high intensity achievable with FRAISE requires the use of appropriate diagnostics and tagging systems that can operate also in a strong radioactive environment. In this framework, a R&D program has been started to develop the FRAISE facility as well as the diagnostics and the tagging systems.
The aim of this paper is the study of the pre-Linnaean herbarium of Paolo Boccone, a 17th century Sicilian botanist. The volume of exsiccata (dated 1680) is currently kept in the Civica and A. Ursino ...Recupero joint Libraries of Catania (shelfmark 1.31.241). The collection was previously unknown and found by chance in 2002 as a result of reorganisation. Herbaria produced by Boccone are to be found in many European cities (Lyons, Paris, Innsbruck, Vienna, Wroclaw, Leiden, Oxford). The one that is the object of this study is, at present, the only one in Italy that exists and that can be consulted. The volume examined consists of 138 pages, with 1-5 specimens on each sheet. The material in the herbarium comprises phanerogams (366 angiosperms and 1 gymnosperm), along with a small number of cryptogams (6 pteridophytes, 1 briophyta and 2 algae). The samples are in a good state of preservation and it has been possible to identify most of them. Most of the taxa are made up of high altitude Alpine and Apennine plants; some entities have a distribution frequency on the Italian territory which goes from rare to very rare and need to be safeguarded because - some more, some less - they are seriously threatened.
Eight species of Ophrys sect. Pseudophrys (Orchidaceae) were cytogenetically studied. The analysed species possess the most symmetrical karyotypes of the genus (MCA ranged from 10.21 to 15.87 and ...CVCL from 19.61 to 23.93) with 2n = 2x = 36, being composed of mainly metacentric chromosomes. The karyotype formulae were: 36m for Ophrys archimedea, 32m + 4sm for O. flammeola, 32m + 4sm for O. funerea, 36m for O. laurensis, 36m for O. lojaconoi, 34m + 2sm for O. lucifera, 34m + 2sm for O. obaesa and 36m for O. pallida. Karyotype morphometric characters were evaluated by calculating MCA and CVCL for the assessment of karyotype asymmetry, and CVCI for the evaluation of heterogeneity in the position of the centromeres. The relationships between species were thus finally elucidated. The species characterised by wide distribution show greater karyomorphological distance than those with restricted distribution. The possible evolutionary role of chromosomal rearrangements as well as gene mutations in the speciation of Ophrys is discussed.
Paolo Boccone (1633-1704), a Sicilian botanist of the second half of the seventeenth century, was a figure who still arouses interest in the emblematic character of his scientific experience, which ...is connected with a personal history that is still in many ways mysterious and unexplored. Elements which help us understand the complexity of the character and the cultural and material difficulties that he had to face are to be found in his works. They have allowed us to build up a picture of his tireless activity as a traveller and his active presence in the majority of European cultural centres of the time.
At the Laboratori Nazionali del Sud of INFN (INFN-LNS) in Catania, the construction of the new Radioactive Ion Beams (RIBs) facility FRAISE (FRAgment In-flight SEparator) has reached its ending ...phase. The facility uses the in-flight technique based on a primary beam fragmentation impinging on light Be or C targets. FRAISE makes use of light and medium mass primary beams, having power up to ≈ 2–3 kW, leading to RIBs, whose intensities vary in the range of ≈ 10

pps, for nuclei far from and close to the stability valley, respectively. FRAISE aims at providing high-intensity and high-quality RIBs for nuclear physics experiments, also serving to interdisciplinary research areas, such as medical physics. Critical aspects for high-quality beams are the tuning and transport, representing time-consuming processes and requiring dedicated diagnostics and tagging devices measuring many features of RIBs. Some of these devices should be capable to operate in radioactively activated environments because of the expected 2 kW beam lost in the dipole after the production target. Due to its peculiar robustness to radioactive damage, Silicon Carbide (SiC) technology has been considered for the detection layer. In this view, an R&D campaign has been started aiming at developing the FRAISE facility, the new diagnostics system, and a new tagging device, the latter of which will be useful for the CHIMERA multidetector beamline. In this paper, we discuss the status and the perspectives of the facility with a focus on the RIBs opportunities.
