Assessment of wet weather impact on clam (Chamelea gallina) faecal contamination in the district of San Benedetto del Tronto (Italy)
Cesare Ciccarelli,Semeraro Angela Marisa,Alessandra Aliventi,Vittoria Di Trani
Italian Journal of Food Safety , 2012, DOI: 10.4081/ijfs.2012.6.46
Abstract: Since 1998 clams (Chamelea gallina) from the production areas of the district of San Benedetto del Tronto (South Marche - Italy) have been periodically monitored to check the microbiological quality by the detection of the faecal indicator E. coli (MPN method). Results have been inconstant. They were not directly related to contamination sources identified by means of a Sanitary Survey. This one included a desk-based study of the physical, geographic, demographic and urban features of the district above and a shoreline survey to confirm or update previously identified sources. With regard to this, several authors found out that meteoric events, in particular rainfalls, increase faecal loading in marine coastal water. This study investigated the impact of rainfalls on E. coli values in clams from the district of San Benedetto del Tronto according to the sampling plan from 2002 to 2011. The study focused on rainfalls occurred until 4 days before mollusc sampling and set up E. coli values into satisfactory and unsatisfactory levels compared to the food safety limit of 230 MPN/100 g. Data were processed by a statistical tool, the Fisher’s exact test. Results revealed the association between precipitations and exceeding values of E. coli in clams collected from coastal waters of most populous areas to be statistically significant.
Traiano Boccalini: la ragion di stato tra satira e sinceritas. Quale accettabilità per Machiavelli ?
Antonella Ciccarelli
Les Dossiers du Grihl , 2011, DOI: 10.4000/dossiersgrihl.4770
Abstract: Les Advis de Parnasse (Venise 1612-1613) de Traiano Boccalini est une uvre satirique dans laquelle l’auteur critique avec un langage allégorique les racines machiavéliques de l’impérialisme de Filippo II soutenues par la papauté de la Contre-réforme. Estimateur d’érasme et de l’irénisme catholique né pendant la Réforme protestante, Boccalini met en scène, dans l’utopique ville-état fondée sur le Mont Parnasse, un dialogue intense entre les différentes ames qui composaient la République littéraire pour revendiquer la reconstitution de la politique sur des bases éthique. Bien que les Advis s’inspirent à la satire de Lucien de Samosate pour traiter le problème actuel, les Observations sur différentes uvres de Cornélius Tacite naissaient comme un traité politique traditionnel où analyser la meilleure forme de gouvernement. Pour Boccalini la République de Venise était le modèle parfait d’état, capable de s’insérer dans la tradition de l’antimachiavellisme vénitien. Son attention vers la dimension éthique de la politique fait de lui un des plus grand critique des lettrés qui écrivaient sur la raison d’état. Les codes de conduite énoncés dans leur travail sont révélés par la satire boccalinienne comme étant la cause des pratiques hypocrites des souverains, la dominante corruption morale de la société moderne et l’aveuglement du peuple, incapable de saisir les principes sur lesquels le mal a été créé pour obéir au pouvoir politique. The ‘News-sheets of Parnassus’ (Venice 1612-1613) by Traiano Boccalini are a political satire in which the author criticizes in allegorical language the Machievellian origins of the Imperialism of Philip II supported by the Counter Reformation papacy. As an admirer of Erasmus and the Catholic irenics born of the Protestant Reformation, Boccalini stages, in a Utopian city state founded on Mount Parnassus, an intense dialogue between the various souls who make up the literary Republic in order to redeem politics by putting it back on an ethical basis. While the ‘News-sheets’ are inspired by the satire of Lucian of Samosata in order to treat the problem of the state, the ‘Observations’ on various works by Cornelius Tacitus are a traditional political treatise which analyses the best form of government. Boccalini takes the Republic of Venice as the perfect model of the state within the tradition of Venetian anti-Machiavellianism. His focus on politics’ ethical dimension makes him one the foremost critics among scholars writing about ‘reasons of state.’ The codes of behavior stated in their works are laid bare by Boccalini’s satire as
The (r)evolution of cancer genetics
Francesca D Ciccarelli
BMC Biology , 2010, DOI: 10.1186/1741-7007-8-74
Abstract: See research article http://www.biomedcentral.com/1741-7007/8/66 webciteRecent advances in sequencing technologies and the launching of massive resequencing projects such as the Cancer Genome Project [1] have boosted the production of cancer genomics data. In the past few years, the entire repertoire of human exons has been sequenced in glioblastoma [2], pancreatic [3], breast and colorectal [4] cancers, and somatic mutations in selected genes have been mapped in multiple samples of renal [5] and lung [6] adenocarcinomas. In addition, the whole genomes of individuals affected by leukemia [7,8], melanoma [9], glioma [10], breast [11,12], and lung [13] cancers have been fully resequenced. All these studies have led to the identification of more than 1,000 potential cancer genes, and the list is likely to grow in the near future.This massive amount of information will have a huge impact on our understanding of cancer genetics, even more so considering that the biological role of most mutations is still obscure. These first unbiased screenings have led to the identification of novel and unsuspected determinants of cancer, such as the isocitrate dehydrogenase enzyme genes IDH1 and IDH2, which have been found mutated in glioblastoma multiforme [2]. They have also started to question some cornerstones of cancer biology, such as the description of cancer as a unique disease driven by the somatic modification of a few key regulators. The progressive identification of novel mutated genes is expanding the 'cast of actors' [14] whose mutations might be causally involved in driving cancer. Moreover, given the high heterogeneity of genes mutated in different cancer types (Figure 1), the overall 'plot' is becoming more intricate. The emerging picture suggests that there may be distinct genetic routes to reach the common aftermath of all tumorigenic processes, which is uncontrolled cell proliferation. For example, as many as 12 core pathways are disrupted in the majority of pancrea
Impedance of the single electron transistor at radio-frequencies
C. Ciccarelli,A. J. Ferguson
Physics , 2011, DOI: 10.1088/1367-2630/13/9/093015
Abstract: We experimentally characterise the impedance of a single electron transistor (SET) at an excitation frequency comparable to the electron tunnel rate. Differently from usual rf-SET operations, the excitation signal is applied to the gate of the device. At zero source-drain bias the single electron transistor displays both resistive (Sisyphus resistance) and reactive (tunnelling capacitance) components to its impedance. We study the bias dependence of the complex impedance, investigating its response as the electron tunnel rate becomes large with respect to the driving frequency. The experimental data are compared to values calculated from a master equation model.
An Overview of Westinghouse Realistic Large Break LOCA Evaluation Model
Cesare Frepoli
Science and Technology of Nuclear Installations , 2008, DOI: 10.1155/2008/498737
Abstract: Since the 1988 amendment of the 10 CFR 50.46 rule in 1988, Westinghouse has been developing and applying realistic or best-estimate methods to perform LOCA safety analyses. A realistic analysis requires the execution of various realistic LOCA transient simulations where the effect of both model and input uncertainties are ranged and propagated throughout the transients. The outcome is typically a range of results with associated probabilities. The thermal/hydraulic code is the engine of the methodology but a procedure is developed to assess the code and determine its biases and uncertainties. In addition, inputs to the simulation are also affected by uncertainty and these uncertainties are incorporated into the process. Several approaches have been proposed and applied in the industry in the framework of best-estimate methods. Most of the implementations, including Westinghouse, follow the Code Scaling, Applicability and Uncertainty (CSAU) methodology. Westinghouse methodology is based on the use of the WCOBRA/TRAC thermal-hydraulic code. The paper starts with an overview of the regulations and its interpretation in the context of realistic analysis. The CSAU roadmap is reviewed in the context of its implementation in the Westinghouse evaluation model. An overview of the code (WCOBRA/TRAC) and methodology is provided. Finally, the recent evolution to nonparametric statistics in the current edition of the W methodology is discussed. Sample results of a typical large break LOCA analysis for a PWR are provided.
Per una pedagogia dello sport: riflessioni dall'Italia
Educación y Educadores , 2009,
Abstract: the current image of sports is fundamentally negative. however, the connection between education and sports should be reinforced, while recognizing it as being hypothetic rather than automatic, and subject to the necessary educational controls. each sport has its own perfection and can contribute to the moral, social, intellectual and ethical development of human beings. the analysis considers some of the areas where that development occurs and underscores a few of the more relevant problems (early competition, education for life, impact of the mass media, etc.) to be addressed for the sake of establishing progress later on.
Identity, Flexibility and Sustainability for the new Social Housing
Cesare Sposito
Techne : Journal of Technology for Architecture and Environment , 2012,
Abstract: Pubblica (lit. Public Residential Construction), undergone over the last sixty years in Italy, have brought about new lines of thought with regard to places to live. The high cost of renewal and re-functionalization of the E.R.P. areas, the absence of services, which have transformed them into dormitory suburbs, have led us to rethink new urban environments as places possessing a sense of identity, in which to provide communal services and spaces for neighborly relations. Moreover, the social, economic and political dynamics of the last few years have modified not only life styles, but also the typology of householder, ever more sensitive to the quality of product and environmental issues. This contribution discusses several principles as a point of departure for a new Social Housing.
Appunti per una lettura di Cléopatre (1829) di Hector Berlioz Notes for a reading of Cléopatre (1829) by Hector Berlioz
Cesare Fertonani
Lanx , 2011, DOI: 10.6092/2035-4797/1264
Abstract: Hector Berlioz compone la sua Cléopatre su un tema indicato per il Prix de Rome del 1829, che era certo di vincere. Proprio per questo motivo, musicando un breve testo di poca ispirazione di Vieillard, ma avendo in mente il monologo della Giulietta shakespeariana sulla sepoltura, Berlioz si sente libero di condurre la sua sperimentazione verso novità audaci in linea con quella poetica del teatro ideale e della memoria che svilupperà in seguito, realizzando l’opera più significativa della sua giovinezza, ma scontentando la giuria del premio. Hector Berlioz composed Cléopatre to compete for 1829 Prix de Rome. He was so sure to win the prize that – setting a short Vieillard’s text to music having in mind Shakespeare’s Juliet monologue about sepulture – he allowed himself to indulge in formal experimentations perfectly coherent with his research about an ideal theater and the theme of memory, both developed in his later years. This is the reason why Cléopatre displeased the jury but remains young Berlioz’s best achievement.
Ensayo analítico sobre el contrabando
Beccaria , Cesare
Revista de Economía Institucional , 2004,
De la tortura (1764).
Cesare Beccaria
Revista de la Asociación Espa?ola de Neuropsiquiatría , 1999,
Abstract: He aquí uno de los capítulos más certeros, más famosos y más eficaces del libro de Beccaria.Poco importa el lector no erudito que parte de los datos y argumentos encerrados en estos párrafos procedan (como afirman algunos críticos italianos actuales) de Pietro Verri, el mentor de Beccaria. En todo caso, quien los divulgó, quien construyó con ellos un capítulo coherente, apasionado, sintético y noblemente efectista, fue Beccaria. Otro acierto suyo consistió en no desgajar la censura contra la tortura de idéntico juicio condenatorio contra todo el sistema procesal penal. Era imposible sustituir la tortura por otras pruebas más objetivas, sin sustituir al mismo tiempo todo el proceso penal ‘ofensivo’ –como lo llama Beccaria en el cap. XL– por otro de carácter meramente ‘informativo’. Beccaria fue, quizá, el primero en comprenderlo así y en así escribirlo. En este punto su vehemente y razonada condena supera en mucho al comentario que sobre la tortura escribió Montesquieu, de quien tantas otras ideas tomó Beccaria . Esta es la nota a De los delitos y las penas que pone su traductor Francisco Tomás y Valiente, gran ilustrado de nuestro presente inmediato, autor de La tortura en Espa a, otro libro indispensable.
