New interesting moss records from the Pollino National Park (Southern Italy).
2016
Some interesting moss records in Pollino National Park, noteworthy protected area of the southern Apennines, are reported. Among them, Mnium spinosum and Brachythecium tommasinii are new to southern Italian peninsula, Grimmia laevigata, G. Montana, G. tergestina, G. trichophylla and Orthotrichum pumilum are new to Basilicata region, and, finally, Campylidium sommerfeltii is rare in southern Italy and little known in Mediterranean area.
Basaltic Rocks Analyzed by the Spirit Rover in Gusev Crater
2004
The Spirit landing site in Gusev Crater on Mars contains dark, fine-grained, vesicular rocks interpreted as lavas. Pancam and MiniâThermal Emission Spectrometer (Mini-TES) spectra suggest that all of these rocks are similar but have variable coatings and dust mantles. Magnified images of brushed and abraded rock surfaces show alteration rinds and veins. Rock interiors contain â¤25% megacrysts. Chemical analyses of rocks by the Alpha Particle X-ray Spectrometer are consistent with picritic basalts, containing normative olivine, pyroxenes, plagioclase, and accessory FeTi oxides. MoÌssbauer, Pancam, and Mini-TES spectra confirm the presence of olivine, magnetite, and probably pyroxene. The…
Mineralogy at Gusev Crater from the Mössbauer spectrometer on the Spirit Rover.
2004
Mössbauer spectra measured on Mars by the Spirit rover during the primary mission are characterized by two ferrous iron doublets (olivine and probably pyroxene) and a ferric iron doublet (tentatively associated to nanophase ferric iron oxide). Two sextets resulting from nonstoichiometric magnetite are also present, except for a coating on the rock Mazatzal, where a hematite-like sextet is present. Greater proportions of ferric-bearing phases are associated with undisturbed soils and rock surfaces as compared to fresh rock surfaces exposed by grinding. The ubiquitous presence of olivine in soil suggests that physical rather than chemical weathering processes currently dominate at Gusev crat…
Structure and physical properties of [mu-tris(1,4-bis(tetrazol-1-yl)butane-N4,N4 ')iron(II)] bis(hexafluorophosphate), a new Fe(II) spin-crossover co…
2004
[mu-Tris(1,4-bis(tetrazol-1-yl)butane-N4,N4')iron(II)] bis(hexafluorophosphate), [Fe(btzb)(3)](PF6)(2), crystallizes in a three-dimensional 3-fold interlocked structure featuring a sharp two-step spin-crossover behavior. The spin conversion takes place between 164 and 182 K showing a discontinuity at about T-1/2 = 174 K and a hysteresis of about 4 K between T-1/2 and the low-spin state. The spin transition has been independently followed by magnetic susceptibility measurements, Fe-57-Mossbauer spectroscopy, and variable temperature far and midrange FIR spectroscopy. The title compound crystallizes in the trigonal space group P (3) over bar (No. 147) with a unit cell content of one formula u…
The Chironomidae (Diptera) in Two Polyhumic Reservoirs in Western Finland
1980
ABSTRACT Composition and distribution of chironomid and other benthic fauna was studied at two adjacent 15 years old polyhumic reservoirs in western Finland by taking benthic and emergence samples. The littoral (0.5 m) coarse debris habitats, previously coniferous forest, had considerably less chironomid larvae (6–7 types, maximally 800 individuals or 0.1 g, AFDW/m2) than the mossgrown habitats, previously peatland (9–10 types, maximally 4000 individuals or 3·4 g/m2). The Chironomus larvae which were dominant at the moss sites were almost lacking at the coarse debris sites. Zalutschia zalutschicola Lipina and Tonytarsus larvae were found only at the deepest areas at 6 m. Altogether 17 speci…
Country-specific correlations across Europe between modelled atmospheric cadmium and lead deposition and concentrations in mosses
2012
Previous analyses at the European scale have shown that cadmium and lead concentrations in mosses are primarily determined by the total deposition of these metals. Further analyses in the current study show that Spearman rank correlations between the concentration in mosses and the deposition modelled by the European Monitoring and Evaluation Programme (EMEP) are country and metal-specific. Significant positive correlations were found for about two thirds or more of the participating countries in 1990, 1995, 2000 and 2005 (except for Cd in 1990). Correlations were often not significant and sometimes negative in countries where mosses were only sampled in a relatively small number of EMEP gr…
The lai “Si bé, Fortuna, has dat lo torn”: a critical edition of the catalan poem from the novel Triste deleitación
2019
The Castilian novel Triste deleitación, written in the late fifteenth century by an author from the Crown of Aragon, includes several letters and poems. One of these poems, “Sy bé, Fortuna, as dat lo torn”, is written in Catalan. This article presents the poem’s annotated critical edition, which reports how it is indebted to the Catalan lyrical tradition. Written in an evolved form of the French lai cultivated by various Catalan poets, the poem is clearly influenced by Pere Torroella’s lai “Qui volrà veure un pobre estat”, and linked to two other similar lais also dependent on Torroella’s. This edition is completed by a translation into modern Catalan. La novel·la en castellà Triste deleita…
Application of 61Ni Mössbauer spectroscopy to chemical problems
1996
Using the possibility to produce 61Co sources at the MAinz MIcrotron, 61Ni Mossbauer spectroscopy was applied to different kinds of chemical problems. Measurements of isomer shifts and V zz values in some common compounds and compounds with unusual chemical bonding for comparison with band structure calculations, measurement of 61Ni Mossbauer parameters in model compounds for hydrogenase and dehydrogenase with an active [NiS4] centre, and study of novel binary NiF3 compounds at helium temperature are presented.
Riflessi dell'etnomusicologia in Sicilia: la "Due canzoni natalizie etnee trascritte dalla memoria per 11 strumenti" (1982-83) di Francesco Pennisi
2022
The text starts from some reflections on ethnomusicological research in Sicily and on the relationship between cultured composers and music of oral tradition. In particular, the genesis and compositional structure of the "Two Etna Christmas Songs transcribed from memory" of 1982-83 is reconstructed.
Inclusive Design for Alzheimer’s Disease: Low-cost Treatments, Design and ICT
2019
Inability to acquire new memories, difficulty to remember recent events and to recognize objects, places and people, visual-spatial disorientation, these are some of the disorders with which who is affected by neurological diseases must learn to live with. In a continuously evolving society, where the decreasing birth rate and the drops in mortality are consistent, the job of Architecture is precisely to interpret the requirements and needs of people who have lost the canonical relationship with the world and give them the possibility to recover it or maintain it through communication channels that use their remaining ability to understand. The indoors and outdoors acquire a “prosthesis fun…
