Paysage et médiatisation dans les Alpes françaises - Approche géographique de la diffusion des cartes postales paysagères
2010
The usual little holiday ritual, landscape postcards have for first purpose to maintain the social link between people going on holiday and people staying at home. But, by giving a view of a certain area from a different place, those postcards represent an original manner to apprehend touristic places and to answer a seemingly simple question: Why this landscape would be sold on that particular spot ? This theoretical question leads to other questions: Is there a hierarchy among those touristic sites? Would the lack of attractivity of several territories cause their eviction? Would the media coverage of sites have effects upon the destruction of territories ? To answer all those questions, …

Towards an ideal source of mesenchymal stem cell isolation for possible therapeutic application in regenerative medicine.
2014
Background. The possibility of obtaining mesenchymal stem cells (MSCs) from fetal tissue such as amniotic fluid, chorionic villi and placenta is well-known and a comparison between MSCs originating in different sources such as fetal tissue and those from bone marrow in terms of yield and function is a topical issue. The mesenchymal stem cells isolated from bone marrow are well-characterized. Unfortunately the low quantitative yield during isolation is a major problem. For this reason, other tissue sources for MSCs are of paramount importance. Conclusion. In this review, starting from a description of the molecular and cellular biology of MSCs, we describe alternative sources of isolation ot…
ANALISI DELLE SERIE TEMPORALI DI DATI PROVENIENTI DALLA RETE DI STAZIONI PERMANENTI DELL’UNIPA
2010
La sperimentazione è stata finalizzata all’analisi dei dati acquisiti dalle stazioni permanenti durante l’arco temporale compreso tra la GPS weeks 1490-1542 e corrispondente al periodo tra Luglio 2008 e Luglio 2009. L’analisi di serie temporali di coordinate provenienti da stazioni GNSS risulta un utile strumento da applicarsi, con diverse finalità, sia a monte che a valle del processo di trattamento dei dati misurati. L’analisi di serie temporali trova la sua principale applicazione, in ambito geodetico, nell’analisi delle deformazioni e nella definizione del datum, che, nella più moderna accezione è espresso a quattro dimensioni e considera anche la coordinata temporale. La SP di Alcamo n…
Selective determination of trimethylamine in air by liquid chromatography using solid phase extraction cartridges for sampling.
2004
Abstract The selective determination of trimethylamine (TMA) in air by liquid chromatography is reported. Sampling is effected by flushing air through C18-packed solid-phase extraction (SPE) cartridges at a flow rate of 15 mL/min for 15 min. Next, TMA is desorbed from the cartridges and injected into the chromatographic system. The analyte is then selectively retained on a precolumn ( 20 mm ×2.1 mm i.d., packed with 30 μm, Hypersil C18 phase), and derivatized on-line by injecting 9-fluorenylmethyl chloroformate (FMOC). Finally, the TMA-FMOC derivative is transferred to the analytical column ( 125 mm ×4 mm i.d., LiChrospher 100 RP18, 5 μm), and monitored at 262 nm. The method was applied to …
Automated Photo-Induced Fluorescence Determination of Flumetsulam
2009
The present article deals with a new procedure for determination of the herbicide flumetsulam. The fluorimetric procedure is performed on the basis of photo-increased fluorimetric emission of the pesticide solution and by means of a multicommutation continuous-flow assembly. The alkaline solution containing the analyte is irradiated online and then directly forced through the fluorimeter flow cell. The analysis of different samples is completely automated, as the analyte separation was performed online by including a separation cartridge in the manifold. When dealing with solid samples (such as soil samples), the automation was completed by adding to the manifold the corresponding device fo…
More about sampling and estimation of mercaptans in air samples
2013
[EN] Several strategies have been developed for sampling and determination of volatile thiols. The selectivity and sensitivity of the proposed methodologies are achieved by using a specific derivatizing reagent. The different procedures assayed are based on air sampling followed by derivatization of the analytes with OPA and isoleucine in alkaline solution. The derivatization products are separated and determined by liquid chromatography and fluorescence detection. To start, the derivatization conditions and stability of the derivates have been studied in order to establish the storage conditions. In general, the strategies studied consisted on trapping and detivatization the thiol compound…
Replanteamiento de fondo en la enseñanza de la filosofía : temas y apropiación
2017
Deeply rethinking the teaching of philosophy: problems and appropriation Resumen: ?Para que sirve la filosofia? es la pregunta que se hace desde fuera de la comunidad filosofica y cuya respuesta puede abrir puertas o poner serios obstaculos a su consolidacion como asignatura. El permanente cuestionamiento externo por la “falta de utilidad” y la constante labor apologetica que genera, parecen ser un indicio de que la filosofia requiere innovacion en algunos aspectos de su ensenanza. A fin de contribuir con este esfuerzo es imprescindible identificar los problemas, y se determina que la falta de interaccion con la ciencia puede ser uno de ellos. Se presentan dos ideas que se enlazan metodolo…
Karthago provinciae nostrae magistra venerabilis. Uno sguardo su Cartagine: i Florida di Apuleio
2023
This paper proposes a focus on the city of Carthage through Florida: Apuleius lavishes continuous and extraordinary praise on Carthage and its citizens. It becomes clear how the city, in Apuleius' time, was by then an established and ‘Romanised’ cultural centre. In Apuleius' words, Carthage appears as the only city capable of competing with Rome.
