Conduit dynamics and post explosion degassing on Stromboli: A combined UV camera and numerical modeling treatment.

2016

Abstract Recent gas flux measurements have shown that Strombolian explosions are often followed by periods of elevated flux, or “gas codas,” with durations of order a minute. Here we present UV camera data from 200 events recorded at Stromboli volcano to constrain the nature of these codas for the first time, providing estimates for combined explosion plus coda SO2 masses of ≈18–225 kg. Numerical simulations of gas slug ascent show that substantial proportions of the initial gas mass can be distributed into a train of “daughter bubbles” released from the base of the slug, which we suggest, generate the codas, on bursting at the surface. This process could also cause transitioning of slugs i…

Essential oils from three Algerian medicinal plants (Artemisia campestris, Pulicaria arabica, and Saccocalyx satureioides) as new botanical insectici…

2020

Medicinal and aromatic plants represent an outstanding source of green active ingredients for a broad range of real-world applications. In the present study, we investigated the insecticidal potential of the essential oils obtained from three medicinal and aromatic plants of economic importance in Algeria, Artemisia campestris, Pulicaria arabica, and Saccocalyx satureioides. Gas chromatography coupled with mass spectrometry (GC-MS) was used to study the essential oil chemical compositions. The three essential oils were tested against a mosquito vectoring filariasis and arboviruses, i.e., Culex quinquefasciatus, a fly pest acting also as pathogens vector, Musca domestica, and an agricultural…

Instagram w autoprezentacji politycznej. Analiza wizualna postów polskich kandydatów do Europarlamentu w 2019 roku

2020

This article reviews currently available literature on the role of Instagram in political communication and reports on the results of the analysis of 1976 Instagram posts of the most active politicians during the 2019 European parliamentary election campaign in Poland. With the aid of quantitative thematic analysis and qualitative visual rhetorical analysis, we identify the main patterns of self-representation of candidates and compare the forms of visualization and typical strategies of building ethos and mobilizing the voters across parties. We prove that traditional representations of candidates (delivering speeches, canvassing, shaking hands) and national (rather than European) symbols …

Analisi del comportamento flessionale del legno attraverso la interferometria Speckle

2009

Nel lavoro vengono presentati i risultati di uno studio sperimentale effettuato sul comportamento flessionale di due differenti essenze di legno: l’abete rosso ed il ciliegio. L’analisi viene effettuata sottoponendo il provino al test di flessione a quattro punti ed utilizzando la interferometria speckle, una tecnica di misura non a contatto ed a campo intero, che consente di ottenere i campi di spostamento e di deformazione sulla superficie del provino. Al fine di mettere in evidenza le peculiarità del comportamento flessionale del legno i risultati ottenuti vengono confrontati con quelli di un provino di Plexiglas nelle stesse condizioni. Tale confronto conferma la complessità del comport…

Cross-Border Higher Education : The Expansion of International Branch Campuses

2022

AbstractThe international expansion of higher education has intensified in recent decades with a rapidly growing number of international branch campuses appearing on the scene. This study investigates the economic, cultural and institutional, and educational determinants of transnational higher education on both the extensive margin (number of international branch campuses), and the intensive margin (the total number of educational programmes offered). Using the gravity equation, we applied fixed-effect empirical methods to a panel dataset that combined and extended the raw data from campuses and master’s programmes in 33 source countries and 76 host countries in the period from 1948 to 201…

Intangibles Disclosure Information on Internet by Multinational Corporations

2003

Rapid developments in information and communications technology, especially with regard to Internet, have caused a substantial impact on the delivery and dissemination of business information. Internet reporting is expected to bring significant benefits to reporting companies, including facilitating access to potential investors an other stakeholders, disseminating information more quickly, more widely and at less cost, providing a platform to integrate different technologies and reducing the cost of providing hard copy annual reports. In this paper, we have examined the extent and the way companies use Internet to provide information about their intangibles. We have established for the Sta…

"Me llaman el desaparecido" : coexistencia y continuidad entre la desaparición forzada y la desaparición social

2020

En este trabajo analizo una de las formas del desborde contemporáneo de la categoría de "desaparición", por la cual ésta pasa a designar formas de invisibilidad, exclusión y violencia muy diferentes a la que definía su marco originario. En particular, me detengo en el trazado de una relación de continuidad entre las formas de la desaparición forzada originaria -ejemplificada en el caso emblemático de la dictadura militar chilena- y las formas de "desaparición social" en las democracias liberales contemporáneas. A partir de la puesta en relación de conceptos políticos como campo, doctrina del shock o excepción, y del análisis de algunos productos culturales, exploramos la posibilidad de habl…

Postilla all'opera di Andrea Camilleri

2022

The language of the novels of Andrea Camilleri is idiosyncratic, accreting onto Sicilian dialect like a saprophyte. However, the novels of Camilleri have had greater national literary success in Italy in the last 30 years. The first part of this text will attempt to explain the reasons for this cultural phenomenon, against the backdrop of the Italian linguistic panora- ma. The second part gathers together aspects of Camilleri’s prose, which shed light on the nature and origin of his literary expression.
