A problematic zygopleuroid gastropod Acanthostrophia revisited
No full textSEM examination of the type series of Acathostrophia acanthica CONTI & FISCHER, 1984 from Middle Jurassic of Italy has shown that this gastropod most likely belongs to the family Protorculidae as previously suggested by NÜTZEL (1998). It is also similar to some Jurassic species of Polygyrinidae, which might also be related to Protorculidae. The supposition of KAIM et al. (2008) that Acanthostrophia is an early member of Abyssochrysidae could not be confirmed
Contribution to the taxonomy of the knowledge of the Italian and northern Balkanic taxa in the Centaurea rupestris group (Asteraceae).
No full textThe morphology of the Italian-Balkanic populations of the Centaurea rupestris group
was studied in order to clarify the taxonomy. The names C. ceratophylla, C. arachnoidea,
C. adonidifolia, C. dichroantha, C. rupestris var. inermis are lectotypified.
The taxonomic status of C. adonidifolia was re-evaluated and a new combination is
suggested: C. arachnoidea subsp. adonidifolia (Rchb.) F. Conti, Moraldo & Ricceri,
comb. & stat. nov. The new taxa here described include C. ceratophylla subsp. danielae
F. Conti, Moraldo & Ricceri, subsp. nova and C. arachnoidea subsp. montis-ferrati
Ricceri, Moraldo & F. Conti, subsp. nova
Minuartia glomerata (M. Bieb.) Degen s.l. dans l’Europe sud-occidentale.

Setaceae Mattf. show affinities between Minuartia rostrata prol. burnatii (Rouy & Foucaud)
Graebn. (from SW Alps) and M. cymifera (Rouy & Foucaud) Graebn. (from Spain and France)
with Minuartia glomerata, thus we propose two new combinations: M. glomerata subsp. burnatii
(Rouy & Foucaud) Favarger & F. Conti and M. glomerata subsp. cymifera (Rouy & Foucaud)
Favarger & F. Conti. The comparative examination of many specimens of M. mutabilis allow us to
confirm the systematic existence of M. mutabilis subsp. lesurina (Braun-Blanq.) Favarger & F.
Conti, proposing a new combination

Botrè, A. Alimonti), è depositato presso il Tribunale della Corte Internazionale di Giustizia(L'Aia)nel memoriale difensivo presentato dalla Repubblica Argentina; ed è stato consegnato ai Presidenti di Argentina e Uruguay
La retorica dei diritti fondamentali? Intervista di Roberto Giovanni Conti a Baldassare Pastore e Giorgio Pino
No full textIl testo, nella forma dell’intervista a più voci, tratta dei seguenti temi: a) il peso dell’interpretazione giudiziale in un sistema dove i diritti fondamentali (nazionali e sovranazionali), nel loro intrecciarsi, svolgono un ruolo centrale, e che impone al giudice un controllo di garanzia prestando il fianco alla critica che lo vede “scendere in campo per fare politica”; b) le insidie che l’attività interpretativa nasconde rispetto all’operato del giudice; c) la soggezione del giudice alla legge in caso di lacune
The radical right in Europe, between slogans and voting behavior. IHS Political Science Series No. 123, July 2011
No full textThe paper analyzes the radical right‘s attitudes toward the EU focusing in particular on the level of congruence between the programmatic statements of the central office and the voting behavior of their MEPs. It shows that although radical right parties represent a source of opposition to the EU, within the EP they express their dissent making use of the rules of the game, voting with the opposition more than the other forces do, but voting almost as much with the majority. The party public office in the EP is inserted in the legislative process and even more collusive with the other parties of both sides of the political spectrum than the Eurosceptical rhetoric and statements of central office makes the public believe
Spectroscopic investigations of the H3PO4 and H2O uptake of polybenzimidazole membranes for fuel cells
No full textPolybenzimidazole (PBI) doped with H3PO4 is the most commonly used membrane material for high-temperature polymer fuel cells. Proton conductivity is strongly dependent on acid doping and water content (humidity). Despite these facts, only little is known on the chemical equilibria of all species inside the membrane as a function of the composition of the ternary system PBI - H3PO4 - H2O. This includes details on the proton transfer processes, on the dominant conduction mechanisms and on the condensation equilibria, leading to the formation of diphosphoric acid and higher homologues species.
In this study, Raman and NMR spectroscopy is used to investigate the chemical inter¬actions between H3PO4, H2O and PBI vs. the H3PO4 doping level. We obtained information on the H-bond formation between H3PO4 and the polymer chains, on tautomeric processes as well as on the presence of not directly bound H3PO4 at high doping levels. Investigations were performed with uncrosslinked and crosslinked m-PBI and AB-PBI [1-4]. [1] F. Conti, A. Majerus, V. Di Noto, C. Korte, W. Lehnert, D Stolten, Phys. Chem. Chem.
