LARGE DEFORMATION CREEP BEHAVIOR OF A SOLID POLYMER.
1981
Abstract The effect of loading rate and strain on the creep behavior after sample yielding has been studied in previous communications (14–15) for Mylar in tension and for Lexan in compression. In this work the creep behavior of Lexan samples previously elongated is considered both in tension and in compression. A procedure which collects all the data independently of both loading rate and initial creep strain is proposed.

Necking behavior of low-density polyethylene-isotactic polypropylene blends: A morphological investigation
1984
The tensile behavior of low-density polyethylene-isotactic polypropylene blends was investigated at room temperature. Neck formation and propagation along the whole length of the samples were observed for the whole range of composition. This behavior, which is not indicated by most data available in the literature, was examined in relation to sample morphology by scanning electron microscopy. The results of this investigation indicated some differences between the morphology of these materials and the morphology of blends which do not undergo necking propagation.

The "Fossa della Garofala" in Palermo: a geological site rich in cultural heritage
2008
The Fossa della Garofala is a short, narrow valley, enclosed by sub-vertical banks, which was carved out by the Kemonia creek on the calcarenitic table that makes up the bedrock of the Plain of Palermo. It forms the outermost hem of the Conca d’Oro landscape where, set in an urban area, geologic and geomorphologic features of value join historical cultural values dating from the Punic period to the XIX century. This combination places the entire area in one of the most significant, albeit little known, pages of history: the history of traditional suburban landscape. This rare synthesis of natural and anthropic landscapes offers the opportunity to create theme itineraries of great cultural a…

Petrography and decay of a marly limestone in the cloister of a medieval cathedral in Sicily
2004
This paper deals with a significant process of decohesion of a marly limestone, taking place in the cloister of the medieval Cathedral of Cefalu, a pleasant town on the northern coast of Sicily. After desalination with deionised water and consolidation with ethyl silicate, the decay of the stone became faster. The aim of our study is to characterise the stony material and investigate the observed decay phenomena. The stone, that is a poor building material indeed, is characterised by means of petrographical, chemical and physical analyses on samples taken from the monument. Furthermore, experimental tests are performed in the laboratory in order to highlight the causes of incompatibility be…
THE SCENOGRAPHY OF SERPOTTA STUCCOES REVISITED - MATERIAL AND FORM
2015
The material that lies beneath the smooth shining surface of the stuccoes of the Serpotta family who used to work in Sicily from 1670 to 1730, has been thoroughly studied in previous papers, disclosing the deep, albeit empirical, knowledge of materials science that guided the artists in creating their masterpieces. In this work, attention is focused on the solid perspective and on the scenographic sculpture by Giacomo Serpotta, who is acknowledged as the leading exponent of the School. The study deals with some particular works of the artist, the “small-scaled plastic theatres”, so-called “teatrini”, which he made for the San Lorenzo Oratory in Palermo. On the basis of archival documents an…
DNA Hypomethylation and Histone Variant macroH2A1 Synergistically Attenuate Chemotherapy-Induced Senescence to Promote Hepatocellular Carcinoma Progr…
2016
Abstract Aging is a major risk factor for progression of liver diseases to hepatocellular carcinoma (HCC). Cellular senescence contributes to age-related tissue dysfunction, but the epigenetic basis underlying drug-induced senescence remains unclear. macroH2A1, a variant of histone H2A, is a marker of senescence-associated heterochromatic foci that synergizes with DNA methylation to silence tumor-suppressor genes in human fibroblasts. In this study, we investigated the relationship between macroH2A1 splice variants, macroH2A1.1 and macroH2A1.2, and liver carcinogenesis. We found that protein levels of both macroH2A1 isoforms were increased in the livers of very elderly rodents and humans, a…

Agents Displacement in Arbitrary Geometrical Spaces: An Evolutionary Computation based Approach
2015
In many different social contexts, communication allows a collective intelligence to emerge. However, a correct way of exchanging information usually requires determined topological configurations of the agents involved in the process. Such a configuration should take into account several parameters, e.g. agents positioning, their proximity and time efficiency of communication. Our aim is to present an algorithm, based on evolutionary programming, which optimizes agents placement on arbitrarily shaped areas. In order to show its ability to deal with arbitrary bi-dimensional topologies, this algorithm has been tested on a set of differently shaped areas that present concavities, convexities …

A specific operative protocol set up during the restoration of the Grammichele slate slab
2009
This work deals with the conservation of a slate slab, representing the map of Grammichele, a small town in the hinterland of South Eastern Sicily. The slab was engraved and painted in 1693, just after the tremendous earthquake that distroyed most of the towns in that area. The conservation process is illustrated through three steps: i) archive research; ii) physical chemical analysis of constitutive materials and degradation products; iii) planning and carrying out of the restoration and conservation operations.
Mortars and Plasters under the Mosaics and the Wall Paintings of the Roman Villa at Piazza Armerina, Sicily
2010
The Roman Villa at Piazza Armerina in Sicily, built in many successive steps over the 2nd and 3rd centuries A.D., is renowned all over the world for both the wealth and the refinement of its mosaic floors. In February 2007 the Regional Government of Sicily started a restoration project of the whole archaeological site. The systematic survey and study of all decorative elements highlighted the value of wall paintings, which until then were almost unknown except for casual approaches to specific problems of conservation, carried on without any relation to the far and away famous mosaics. This paper shows the results of a physical chemical investigation of the mortars used for both floors and …
Problems of soil and groundwater pollution in the disposal of “marble” slurries in NW Sicily
2007
This work deals with disposal of slurries generated during the cutting and polishing processes of slabs of decorative sedimentary carbonate rocks in the north western Sicily. At present, they are used as fillers of dismantled quarries near the sawmills and, as a final step of reclamation, are covered with earth layers. In spite of such inexpensive solution, there is lack of knowledge about the composition of the waste. In order to assess if there is any threat for the environment and to suggest indications for alternative solutions, such as recycling or inactivation processes, the slurries were analysed by XR diffraction, simultaneous thermal analysis, ICP/MS, ionic chromatography, FTIR, UV…
Experimental study of stress-relaxation behaviour of polycarbonate after yielding

Can you feel it will you tell me. Encouraging sentiment expression on the web
2015
In a recent trend in web communication, news outlets and blog platforms allow readers to express opinions about what they have read by choosing an associated feeling, or sentiment ex- pression. This emerging trend, fitting between liking and full text comments, has not still found the popularity it should. The thesis of this paper is that this is also due to the way the sen- timent choice is presented to the user. In order to test this hy- pothesis we have devised a pilot experiment; results confirm that a simpler way of choice increases sentiment expression and yields result that are more aligned with ground truth.

Infine è stato progettato ed eseguito l’intervento di conservazione, a…
Effectiveness of Preservative Treatments on Coloured Ruditic Building Stones
2009
: The dark grey Breccia di Billiemi and the Ammonitico Rosso of Piana degli Albanesi, two coloured stones widely used in monuments both outdoor and indoor in Sicily, undergo significant decay as effect of weathering: colour change and development of surface microcracks which affect not only the chromatic aspect but also the state of aggregation. In a previous study (Fracture and Failure of Natural Building Stones, 2006, Springer, Dordrecht, The Netherlands: 329), such effects were successfully reproduced on laboratory samples by means of artificial accelerated weathering and the different response of veins and grains to the ageing agents was related to the microstructure of stones. In this…

Problemi di Conservazione di un'opera di Land Art di straordinarie dimensioni: il Grande Cretto di Alberto Burri a Gibellina (TP)
2009
This work deals with the conservation of one of the largest land art works in the world. It is a sort of white shroud laid on the ruins of the town of Gibellina, Sicily, after the tremendous earthquake of January 1968. The most significant aspects of the degradation phenomena observed on site are related to some faults in the construction, due to the prevailing of the artistic requirements over the good rules of concrete technology. Furthermore the guidelines for both a conservation intervention and the subsequent maintenance of the art work are also indicated.

Le aviorimesse di Pierluigi Nervi a Marsala: correlazioni tra le diverse modalità di esecuzione e lo stato di conservazione
2009
This work deals with the composition and the state of conservation of the concrete of two hangars designed and built by Pier Luigi Nervi in 1940-1941. The interest in this project is related both to the use of on site prefabrication for so large structures (45x55 m plan) and to some peculiarities of the mix design, in particular the aggregate/binder ratio and the lithological composition of the aggregates. The study has been performed by means of X ray diffractometry, optical microscopy in trasmitted light on thin sections, ionic chromatography and carbonation tests. The twofold aim is to assess the conservation condition of concrete after 67 years of ageing in a marine spray environment an…
Physical behavior and morphology of biaxially rolled low-density polyethyleneX
1989
Abstract Biaxial rolling was carried out on low-density polyethylene, and the rolled samples were studied using various techniques. Scanning electron microscopy and analysis of transport properties were used to obtain structural information, which was correlated to thermomechanical and dynamic-mechanical behavior. Results indicate that the initial morphology is destroyed by rolling and that clumps of molecules, like fibrils, are generated parallel to the rolling plane. The molecular orientation in the plane is mainly radial, with some reinforcement, particularly at high rolling degree, along axes diagonal with respect to the rolling directions. The rolling drastically reduces the molecular …
The recovery after bending of polycarbonate sheets
1981
The recovery after bending has been extensively studied for metal sheets. The data presented in this work show that in the case of polymeric materials viscoelastic effects play a very important role. In particular the influence of deformation rate, the time the sample is held under load and the recovery time is analysed. A master curve is obtained by proper modification of a recent analysis developed for metal sheets.

Master curves of viscoelastic behavior in the plastic region of a solid polymer
1977
Stress relaxation and creep tests following strain ramps were made on Mylar, both above and below the yield stress. The ramp velocity was varied over a 40-fold range. All data exhibit nonlinear viscoelastic behavior. However, those obtained above the yield point, i.e., in the plastic region, could be reduced to single master curves for both the creep and the relaxation tests by means of a simple time shift factor. This factor is inversely proportional to the strain rate existing just prior to the test.

Characterization of hydraulic mortars by means of simultaneous thermal analysis
2008
The properties of hydraulic mortars were studied by means of simultaneous thermal analysis (STA), according to a procedure proposed in the literature. Hydraulic limes, cement and/or slaked lime were mixed using different proportions of both inert and reactive aggregates, in order to test the effectiveness of such procedure in distinguishing the different degree of hydraulicity of such samples. The use of the normalized coordinates suggested in the literature results in overlapping of the clusters of different kinds of mortars. Modified coordinates are proposed, which give promising results in view of outlining a 'master curve' of hydraulicity.

Morphology and transport parameters of cold-rolled low-density polyethylene
1986
Abstract Sheets of low-density polyethylene were rolled at room temperature. Samples with two different degrees of rolling were obtained. The structural changes induced by the rolling treatments were investigated using scanning electron microscopy and by analyzing the transport properties. Results suggest that in the analyzed range of deformation, the rolling induces a domain structure as a consequence of a nonhomogeneous distribution of the deformation. At lower local deformation the initial morphology is still present, while at higher deformation clumps of folded chains oriented along the rolling directions are observable. The transport properties indicate that the rolling treatment reduc…
Comparison of thermal expansion of wood and epoxy adhesives
2002
Epoxy-based adhesives are used both in the consolidation of decayed timbers and for new structural joints. Investigating the compatibility of wood and epoxy adhesives provides a better knowledge of the long-term behaviour of wood-epoxy joints. Besides mechanical compatibility, also temperature-related parameters are relevant in this context. The values of the thermal expansion coefficients (TEC) of two wood species (Spruce, Picea abies and Iroko, Clorophora excelsa) and four different epoxy resins have been compared using a modified test method that allows for nearly iso-hygric conditions of the wood specimens. Minor differences in TEC have been observed between wood in the transversal-to-t…
Nudo femminile. Intervento di conservazione di un dipinto incompleto di Giacomo Manzù

Compressive recovery behaviour of a polycarbonate
1978
Abstract Polycarbonate samples were subjected to large compression strains (beyond yielding) and were unloaded after some degree of stress relaxation. The subsequent deformation recovery was measured for several values of strain, loading rate and duration of stress relaxation. All the data could be reported as a single curve by normalizing the recovered strain with the stress at the end of the relaxation period.

Le malte idrauliche dell’Acquedotto Romano di Termini Imerese
2009
Aim of this paper is the characterization of ancient hydraulic mortars from the roman water supply system of Thermae (I-II cent. A.D.), known as “Aqua Cornelia” and "Figurella" aqueducts, more than 10 kilometers long. Because of malfunctioning of the "Barratina" siphon, major changes in the original adduction system were realized in several steps. Mortar samples were taken from both channels lining materials and structural elements, in order to contribute to answer some questions about the construction phases of the aqueduct. The materials characterization was performed by means of XRD analysis, optical microscopy, microRaman spectroscopy and simultaneous thermal analysis. The latter is a u…

A simplified description of viscoelastic behavior of polymers as illustrated with biaxially-oriented poly(ethylene terephthalate)
1978
A rheological model of solid polymers is proposed. Its mechanical analog is a parallel of a linear spring and a Maxwell element with variable viscosity. The viscosity of the dashpot is allowed to change with stress both directly, by an Eyring-type mechanism, and through free volume changes according to the Doolittle equation. Predictions of the model reproduce many of the features shown, especially after yielding, by constant velocity stress-strain, stress-relaxation and creep data taken at room temperature on biaxially-oriented poly(ethylene terephthalate) over a wide range of loading rates.
Caratterizzazione dei residui di lavorazione di materiali lapidei di pregio, finalizzata ad un possibile recupero

A commercial low density polyethylene was irradiated by gamma irradiation at room temperature with different integrated doses and dose rates. The modifications induced in the material were studied by means of solubility and swelling measurements and related to structural modifications by calorimetric measurements. Results indicate that crosslinking prevails with respect to degradation at high dose rates and that the ageing phenomena occur essentially in the amorphous phase. Ein kommerzielles Polyethylen niedriger Dichte wurde bei unterschiedlicher integrierter Dosis und unterschiedlicher Dosisleistung bei Zimmertemperatur mit Gammastrahlung behandelt. Die Veranderungen des Materials wurden …
Towards a fuzzy-linguistic based social network sentiment-expression system
2015
Liking allows users of Social Networks, blogs and online magazines to express their support of posts and artifacts by a simple click. Such function is very popular but lacks semantic power, and some platforms have augmented it by allowing to choose a pictographic depiction corresponding to a feeling. What is gained in depth is lost in simplicity, and the wide acceptance liking has enjoyed did not carried to the sentiment version. We outline a sentiment-expression hybrid system based on textual analysis and linguistic fuzzy Markov chains overcoming the intrinsic limitations of liking without burdening the user with complex choices.
Diagnostic Criteria for Parkinson's Disease: From James Parkinson to the Concept of Prodromal Disease.
2018
The diagnosis of Parkinson’s disease (PD) is based on clinical features and differently to the common opinion that detecting this condition is easy, seminal clinico-pathological studies have shown that up one-fourth of patients diagnosed as PD during life has an alternative diagnosis at post-mortem. The misdiagnosis is even higher when only the initial diagnosis is considered, since the diagnostic accuracy improves by time, during follow-up visits. Given that the confirmation of the diagnosis of PD can be only obtained through neuropathology, to improve and facilitate the diagnostic-therapeutic workup in PD, a number of criteria and guidelines have been introduced in the last three decades.…

Trace metals in “Posidonia oceanica” seagrass from south-eastern Sicily
2005
Heavy-metal concentrations were measured in sediments and tissues of Posidonia oceanica seagrass from south-eastern Sicily (Italy) in order to assess the degree of metal pollution in the coastal area. Seagrasses and sediments were collected at four sites along the south-eastern coast of Sicily. Flame atomic absorption spectrophotometry (FAAS) was used to measure concentrations of Cu, Zn, Cd and Pb. Standard statistical analyses were used to assess significant differences among the levels of the elements measured in different tissues and sediment and spatial distribution. The greatest values of potentially toxic metal concentrations were observed at the station near the industrial sites of A…

Characterization of mortars from ancient and traditional water supply systems in Sicily
2008
Long aged mortars from ancient hydraulic constructions of Sicily, i.e. the Roman aqueduct of Thermae and the Punic cisterns and traditional water supply systems in Pantelleria, have been characterised by means of XRD analysis, optical microscopy and simultaneous thermal analysis to correlate the hydraulic properties to the texture and to their different role in the construction, i.e. lining, covering, roofing and joint mortars. According to a procedure proposed in the literature all of the samples, but two air hardening ones, show high hydraulicity, which somehow can be related to the characteristics of aggregates.
