La questione filosofica dell'inconscio. Inconscio e autocoscienza non riflessiva da Brentano a Husserl

Sviluppo storico sino al 1998 della Scienza delle Costruzioni e della Tecnica delle Costruzioni nell'Ateneo Palermitano

2008

Nel contributo viene tracciata la storia della Scienza e Tecnica delle costruzioni dell'Università di Palermo a partire dalla Reale Scuola di applicazione per ingegneri e Architetti di Palermo, 1866, passando per il Gabinetto di Meccanica applicata alle Costruzioni, 1923, e per i successivi cambiamenti che portarono al Dipartimento di Ingegneria Strutturale e Geotecnica, 1985. Viene inoltre tracciata la storia dell'annesso Laboratorio di prove sui materiali da costruzione attraverso le attività svolte ed i macchinari acquisiti.

Novel organo-modifier for thermally-stable polymer-layered silicate nanocomposites

2015

A new novel approach for the stabilisation of polymer-clay nanocomposites has been investigated based on reacting chemically an antioxidant function, a hindered phenol moiety, with an organic modifier based on a quaternary ammonium salt. The chemically linked antioxidant-containing organic modifier (AO-OM) was then introduced into natural montmorillonite (MMt) through a cation-exchange reaction resulting in antioxidant-containing organo-modified clay (AO-OM-MMt). The new antioxidant-containing modified clay, along with other organo-modified clays having a similar organo-modifier but without the reacted antioxidant, were characterised by spectroscopic, thermogravimetric and x-ray diffraction…

Interrelazioni tra disfunzione endoteliale e stress ossidativo; valutazione della perossidazione lipidica in particolari quadri clinici

2015

Il termine "disfunzione endoteliale" identifica una condizione patologica caratterizzata da ridotta vasodilatazione e da attività procoagulante e pro-infiammatoria, correlata ad una ridotta biodisponibilità di ossido nitrico (NO), ad un eccesso ossidativo e ad un'aumentata azione dell'endotelian 1 (ET-1).

An Interface Model for the Analysis of Anisotropy of Friction and Wear of Contact Surfaces

Effective reference and current integration for large displacement interface

2016

The most common interface formulations proposed in literature are generally based on the restrictive hypothesis of small strains and small displacements and, even though their application to geometrically nonlinear problems is of paramount interest, only few contributions are available in literature. Motivations are probably due to the difficulties encountered on such formulation, as already mentioned by several authors. A pioneering formulation is the finite displacement three-dimensional interface developed by Ortiz and Pandolfi in [1], where normal and tangential traction components are evaluated with respect to the middle surface in the current configuration, producing a non-symmetric g…

Interface model for the nonlinear analysis of blocky structures of ancient Greek temples

2010

The presence of singularity surfaces with reference to the displacement field is a characteristic of a number of structural systems. Strong discontinuities are present in old masonry structures where dry joints connect the blocks or the mortar ageing suggests to neglect the adhesion properties. These structures cannot be considered a continuum but rather an assembly of blocks. These discontinuous structures could be modelled as an assembly of blocks interacting trough frictional joints whose mechanical behaviour is described by appropriate interface laws. In the present work an interface model present in literature is adopted, the double asperity model, which has been implemented in a stand…
