Quantitative Multispectral Imaging Differentiates Melanoma from Seborrheic Keratosis.

2021

Melanoma is a melanocytic tumor that is responsible for the most skin cancer-related deaths. By contrast, seborrheic keratosis (SK) is a very common benign lesion with a clinical picture that may resemble melanoma. We used a multispectral imaging device to distinguish these two entities, with the use of autofluorescence imaging with 405 nm and diffuse reflectance imaging with 525 and 660 narrow-band LED illumination. We analyzed intensity descriptors of the acquired images. These included ratios of intensity values of different channels, standard deviation and minimum/maximum values of intensity of the lesions. The pattern of the lesions was also assessed with the use of particle analysis. …

Warm white LED light by frequency down- conversion of mixed perylene-based dyes

2013

The growing demand of the solid-state lighting market for the development of sources for illumination has led to the fabrication of the first white LED in 1997, which employed a blue LED coated by a Ce:YAG phosphor to mix the down-converted yellow light with the blue one. The white light appears cold due to the weakness of red components in the emission spectrum. In order to obtain a warmer white, one possible solution is to add a red phosphor to the yellow one to move the chromatic coordinates properly, though the luminous efficiency drastically decreases due to the increased light absorption of the coating layer. It is generally believed that the low efficacy of warm white LEDs is the mai…

La scoperta, sistemazione e conservazione della grande Iscrizione di Gortina, nell'isola di Creta (1884-1921): la protezione delle testimonianze e le…

2013

La scoperta e la conservazione della Grande Iscrizione di Gortina a Creta, da parte degli studiosi italiani, fra la fine del XIX sec. e i primi decenni del XX sec., rappresentò un grande riconoscimento scientifico-culturale per la giovane nazione italiana. Nel passato, l’isola di Creta era stata legata alla Repubblica di Venezia e anche questo rapporto favorì l’invio a Creta del giovane epigrafista F. Halbherr, il quale fra notevoli peripezie rinvenne, assieme all’epigrafista tedesco E. Fabricius, la famosa l’iscrizione nell’antica città di Gortina. L’iscrizione, fra le più antiche e complete finora conosciute in tutta Europa, conteneva le norme sulla famiglia, l’eredità e in generale i dir…

The discovery and preservation of the Great Inscription of Gortyna in Crete by Italian researchers in the late nineteenth century. and the first decades of the twentieth century. was an important cultural and scientific recognition for the young Italian nation. In the past the island of Crete had been tied to the Republic of Venice and this report also favored sending in Crete the young epigraphist F. Halbherr who among considerable vicissitudes came to together to the epigraphist german E. Fabricius the inclusion of the famous ancient city of Gortyna. The inscription among the oldest and most comprehensive so far known throughout Europe the rules contained on the family's legacy in general and the rights and duties of some of the people of the Minoan civilization (480-450 BC). The inscription was carved on blocks organic limestone a restored ancient building which later in Roman times was turned into odeon. The Laws of Gortyn were engraved on the remains of the wall forming the passageway in front of the steps of the odeon. The essay traces the events that led to the discovery and subsequent storage made by Halbherr especially with the help of archaeologist L. Pernier and finally with the help of architect E. Stefani who designed a modern cover on the top of the ambulatory of the segments containing the inscription. This coverage was made to perform during the First World War on the basis of the Italian project from the Greek Government in order to protect the membership from possible war damage but especially from vandalism. The roof brick clay of the Laws of Gortyna still serves its function and ensures the use of the monument bearing witness to the preservation of Italian culture in Greece and more generally in the world. But in Sicily in the remains of the Villa del Casale in Piazza Armerina (Enna) its elegant protection (built in 1957) is representative of a whole period of culture of the Italian restoration is removed and replaced because it has not been able to make a ongoing maintenance is due. A bad example of conservation and management of a UNESCO monument from which arise after the work for the construction of new roofs an equally insulting to the archaeological heritage and scenic Italian and world.Settore ICAR/19 - Restauro

Il lavoro etero-organizzato prima e dopo il caso Foodora Italia.

2019

l contributo ripropone la discussione sull’esegesi della fattispecie disciplinata dall’art. 1 comma 2 del d. lgs. n. 81 del 2015 (nel testo anteriore alla riforma del 2019) trattata dall’autore nei Colloqui Giuridici sul Lavoro del 2015 (a cura) di Antonio Vallebona per il Massimario di Giurisprudenza del Lavoro. Lo studio rigettava la tesi che il lavoro organizzato dal committente fosse la terza fattispecie e anzi con riferimento delle condizioni di applicazio­ne dimostrava la necessità di una lettura includente. La conclusione era che la nuova disciplina aveva natura antifraudolenta e determinava un allargamento (relativo) dell’area della subordi­nazione conseguente alla riduzione del cam…

This article republishes (after the Italian Supreme Court judgement n.166/2020 on the Foodora Italia case) the contribution to the exegesis of the case brought by art. 1 para­graph 2 of the d. lgs. n. 81 of 2015 (in the text before the 2019 reform) delivered by the author in the 2015's "Colloqui Giuridici sul Lavoro" (edited) by Antonio Vallebona for the "Massimario di Giurisprudenza del Lavoro". The study rejected the thesis that the job organ­ised by the client was an intermediate regulation between the employee and the self-employed ones. Indeed regarding the conditions for its application it showed the need for extensive reading. The conclusion was that the new discipline was (and is) an anti-fraudulent one. It led to a (relative) expansion of the area ofsubordination as a consequence of a reduction in the scope of coordinated self-employed work. A little more than four years after that article the Italian Supreme Court (with the judgement n.166/2020) on the Foodora Italia case addresses for the first time the issue of the hetero-organised work (by art. 1 paragraph 2 of the d. lgs. n. 81 of 2015). The Supreme Court fully adheres to the paper's thesis. So in terms of the "re­medial" function of the standardthe nature of the organisation's specific conditionand eventually reducing the legal frame for coordinated work. The fact that the procedural matter dealt with the riders was (then and now is) utterly irrelevant for the correct interpretation of such a new provision. Giving to riders of the employee status is not an effect of the peculiarit­ies of the work through digital platforms. It is a consequence of the remedial nature of such a case-law.

Interaction model: Reflexiv leadership in the face of tensions in the school’s practical day to day handling

2023

Author's accepted manuscript Rektorer opplever utfordringer i det å arbeide som faglig, pedagogisk og administrativt ansvarlig på skolen. Faglig, pedagogisk og administrativt hensyn kan fort komme i konflikt med hverandre og skape spenninger i rektors arbeid. Denne artikkelen undersøker rektorenes opplevelse av å være leder på skolen, og hvordan de kan håndtere disse spenningene. For å komme så nære rektorene som mulig er det benyttet reflektive livsverdensintervjuer. Resultater i denne artikkelen støtter tidligere resultater i nordisk forskning om at administrative oppgaver tar fokus bort fra utviklingsoppgaver og at det er spenninger mellom ulike oppgaver i rektors arbeid. For å illustrer…
