The reference section of the Sardinian Ockerkalk: the Silius Section
No full textThis locality has been stratigraphically studied mostly in the last decade (Barca et al., 1994, 1995; Serpagli et al., 1998). Together with the nearby Genna Ciuerciu Section, theSilius Section is a reference section for the Sardinian Ockerkalk, and, being the mostcomplete, it is candidate as stratotype of the unit as soon as it will be formally presented.This section is the type locality of two conodont taxa: Kockelella variabilis ichnusae Serpagli & Corradini and Pseudooneotodus bicornis contiguus Corradini. Furthermore it is one of the key-sections for the Silurian Conodont Zonation proposed by Corradini & Serpagli (1998, 1999)
First documentation of the Polygnathoides siluricus conodont Zone (Ludfordian) in South America (Argentina) and the stratigraphic significance of the younger species of Kockelella (Conodonta)
No full textThe coquinoid beds from the middle part of the Los Espejos Formation at the Poblete creek section (Talacasto Creek) yielded abundant conodonts. The genus Kockelella (Walliser) represents the most relevant biostratigraphical genus in this conodont
fauna. The co-occurrence of Kockelella maenniki Serpagli and Corradini, Kockelella variabilis ichnusae Serpagli and Corradini, K. variabilis Walliser, Kockelella ortus sardoa (Serpagli & Corradini), and Kockelella ortus absidata (Barrick & Klapper) allow us to
record for the first time the Polygnathoides siluricus Zone in South America, which suggests the Ludfordian Stage (late Ludlow). We also propose an accurate correlation of the Los Espejos Formation with the lower Ludfordian deposits from the Carnic Alps, Sardinia, Morocco, Czech Republic, Gotland, and North America

Un intellectual italiano en América Latina: el viaje de Enrico Corradini de 1908 y las origenes del nacionalismo en Italia
No full textIn the first decade of the XX century the Italian «various nationalism» found one of its most prominent members in Enrico Corradini, able to transform a generic desire of power in a concrete political action. Latin America had a significant weight in the evolution of the ideas of Corradini, who in 1908 travelled to Brasil and Argentina, visiting the two countries and meeting the Italian communities. Thanks to the travel, documented by the correspondences sent to the Corriere della Sera and mentioned in several following works, the writer developed ideas that had a great relevance for the rise of Italian nationalism. In the emigrants Corradini found an evidence of the weakness of Italy, which was unable to assist its expatriated citizens and to keep their sense of national identity. The article, based on Corradini’s works and on the press of the period, aims at examining how the travel influenced his political thought and, more in general, how it contributed to the development of Italian nationalism.Durante la primera década del siglo XX, Enrico Corradini fue uno de los más destacados representantes del “variado nacionalismo” italiano, él que más que otros supo transformar un genérico sentimiento de potencia en una concreta acción política. América Latina fue muy importante para la evolución de las ideas de Corradini, el cual, en 1908, viajó a Brasil y Argentina, visitó los dos países, y encontró las comunidades italianas que allí residían. A partir del viaje –documentado por las correspondencias enviadas al Corriere della Sera y recordado en diferentes escritos posteriores– él llegó a conclusiones fundamentales para el desarrollo del nacionalismo. En los emigrados, Corradini encontró una prueba de la debilidad de Italia, que no era capaz de ayudar a sus compatriotas expatriados para permitirles preservar el sentimiento de identidad nacional. El ensayo se basa en los escritos de Corradini y en la prensa de su época, y pretende reconstruir cómo el viaje latinoamericano ha influido en su pensamiento político y, más en general, cómo ha contribuido al desarrollo del nacionalismo italiano
Pragian to Famennian depositional evolution of the M. Pizzul area (Carnic Alps, Italy): preliminary results
No full textThe Carnic Alps represents the non- to low-grade metamorphic portion of the Variscan substratum of the Alps (VAI 1976, SCHÖNLAUB 1979). The whole “pre-flysch” Variscan succession of the Carnic Alps is thought to have developed in correspondence of a mainly carbonate platform not deeper than few hundred meters. Up to the Pragian, the basin physiography can be roughly schematized as a ramptype, while from the Pragian to Famennian differential carbonate growth controlled by tectonics led to a differentiation between shallow water facies, high-density and low density resedimented gravitative driven deposits and deeper water facies. The study area of the M. Pizzul is located in the central part of the Carnic Alps, south of Cason di Lanza Pass and east of Mt. Zermula

No full textStructural Properties of High and Low Density Water in a Supercooled Aqueous Solution of Salt
No full text"We consider and compare the structural properties of bulk TIP4P water and of a sodium chloride aqueous solution in TIP4P water with concentration c = 0.67 mol\/kg, in the metastable supercooled region. In a previous paper (Corradini, D.; Rovere, M.; Gallo, P. J. Chem, Phys. 2010, 132, 134508) we found in both systems the presence of a liquid liquid critical point (LLCP). The LLCP is believed to be the end point of the coexistence line between a high density liquid (HDL) and a low density liquid (LDL) phase of water. In the present paper we study the different features of water water structure in HDL and LDL both in bulk water and in the solution, We find that the ions are able to modify the bulk LDL structure, rendering water water structure more similar to the bulk HDL case. By the study of the hydration structure in HDL and LDL, a possible mechanism for the modification of the bulk LDL structure in the solution is identified in the substitution of the oxygen by the chloride ion in oxygen coordination shells.

Proposed revision of the Famennian (Upper Devonian) standard conodont zonation
No full textThe proposed revision of the Famennian part of the Late Devonian Standard Conodont Zonation of
Ziegler & Sandberg (1990) is the result of two main different kind of considerations. The first is
philosophical, and consists in refusing: (1) the equivalence between biozones and time, and (2) the presumed phyletic concept on which this zonation was based. The second is practical, and deals with: (1) solving difficulties arose in the recognition of some biozones defined by Last Appearance Datum (LAD), (2) simplifying the zonation eliminating the zonal groups named after only one taxon.
This revision is largely based on the zonation of Ziegler (1962) and the Late Devonian Standard
Conodont Zonation of Ziegler & Sandberg (1990) using mostly the same zonal markers, therefore it is
perfectly correlatable with them. Modifications have been only made when strictly necessary, as the aim of the proposal is not to destroy what was previously well done, but to improve and simplify the Standard Conodont Zonation, keeping stability over more than 50 years of conodont studies. The 22 zones constituting the revised zonation are defined by the First Appearance Datum (FAD) of species and subspecies whose stratigraphic ranges are well known, and have wide geographic distribution (Fig. 1), most of which have already been used as markers. Each zone is named after the species or subspecies whose FAD defines the lower boundary. The main changes regard the upper part of the Famennian, and take into account proposals already made by other authors, at least for regional zonation (Corradini, 2008; Kaiser et al., 2009; Hartenfels, 2011; Corradini et al., submitted). The stratigraphic distribution of most Famennian conodont taxa has been updated on data available in literature, and unpublished information of the authors.
The lower boundary of the Famennian is identified as proposed by Klapper (2007), a revision of the current
definition of the base of the Famennian is therefore suggested. The definition of the upper boundary (base of the Carboniferous System) is currently under discussion and study
