The archaeological excavations, started by Charles of Bourbon in 1738, for the rediscovery of ancient Herculaneum posed problems of restoration and conservation never faced before: bronzes, marbles and mosaics were restored according to the techniques of the time. A significant problem arose for the frescoes that lost color a few days after extraction from the lava of the eruption of Vesuvius in 79 AD. The Neapolitan court also sought help outside the Kingdom, but the solution was found by a soldier, Stefano Mariconi, with the invention of a paint that allowed the colors to be maintained. For some years he provided his support as needed, regularly paid until his death. He did not reveal the formula of his paint except to his wife Rosa Percolla who after 1748 continued his work for a few decades, and finally revealed the formula in exchange of a pension. The archival documentation tells, in great detail, the vicissitudes that allowed the frescoes to be saved and the story told to the Repubblica delle Lettere through the publications of the Royal Printing House.

Studying the chronicles written by Paul the Deacon, Erchempert and the Anonymous of Salerno the scholar will quickly spot a contradiction: the authors tend to overstate the military prowess of the Langobard people, but at the same time fail to adulterate a reality that is way less flattering. Where does this myth of military prowess come from? From the Langobard chroniclers' hurt pride? Or are there further reasons tied to the need to legitimize the military élite? Through a punctual analysis of the chronicles and the most recent historiography, the author proposes an interpretation of the possible motivations that led the said chroniclers to produce their work.

Dado que la máquina sincrónica en su funcionamiento como generador constituye un elemento vital en los sistemas eléctricos de potencia, el desarrollo de programas y técnicas de mantenimiento predictivo, a fin de identificar y solucionar problemas en la máquina antes de que se produzcan daños irreversibles en la misma es prioridad. A continuación se establece una metodología para detectar fallas incipientes en rodamientos de un generador sincrónico de prueba a través de máquinas de vectores de soporte (SVM por sus siglas en inglés). Se presenta el análisis de las corrientes de fase, utilizando métodos variados para la reducción de los datos y algoritmos de aprendizaje automático basados en las máquinas de vectores de soporte como elemento clasificador de datos; a fin de obtener un modelo que sea capaz de discriminar la condición de una máquina, en cuanto a fallas mecánicas se refiere. El entrenamiento de las máquinas de vectores de soporte para obtener los criterios de clasificación se ejecutó utilizando los comandos para SVM de MatLab, las funciones que brinda este software permitieron: el entrenamiento, la optimización y la posterior validación de los clasificadores. Los resultados obtenidos demostraron que el método aplicado basado en la SVM posee una buena capacidad de reconocimiento de fallas presentadas en los diferentes componentes del rodamiento, para distintas condiciones de operación.

The levels of PCDDs, PCDFs and DL-PCBs were analyzed both in milk and adipose tissues sampled “in vivo” from lactating, drying off and heifer buffaloes from a Campania farm which had been impounded by the competent authority owing to the high dioxin levels found in bulk milk. The chemical determination was carried out by HRGC-HRMS using US EPA Method 1613b. The range of WHO-TEQ values for the PCDDs/PCDFs in adipose tissues was 1.79 to 68.64 pg g−1 fat and in milk was 8.33 to 13.95 pg g−1 fat. The contamination profile for dioxins and furans was given by 1,2,3,7,8-PeCDD; 2,3,4,7,8-PeCDF; 1,2,3,6,7,8-HxCDD and 2,3,7,8-TCDD. The levels of DL-PCBs in adipose tissue varied from 1.38 to 20.13 pg g−1 fat while ranged from 8.33 to 13.95 pg g−1 fat in milk. The pattern of DL-PCBs in both matrices was dominated by congeners PCB 126 and PCB 169.

The basic intenet of this paper is that the song by Arnaut Daniel under discussion is an ironic and polemic, or perhaps a sarcastic and polemic hymn to the masochism of fin’amor of the hard and fast kind, the kind that involves impossible love leading to endless suffering caused by constant, insatiable desire for satisfaction. Bearing this in mind, the paper argues that up to the end of the sixth cobla, the lyric voice is both masochistic lover, a dedicated follower of fin’amor, and disillusioned censurer of this form of love, which borders on pathological deviance and mania: thus, at the same time it is both the patient and the illness’s conscience.

Doi: 10.12957/geouerj.2015.19677 Expo Milan 2015, whose theme was “Feeding the planet, Energy for life”, offered visitors a trip around the world across cultures and innovations in the participating countries. In the past, these events generally represented a moment of celebration of the power of technology and economy as engines of unlimited progress; the event made in Italy, however, offered a new paradigm, placing as a central issue the question of development models, in a sociological, political and anthropological view overcoming inequalities that today characterize relations between nations and people. Italy and Brazil, the great protagonists of the event, presented a view of their excellence in the field of feeding. Their aim was to contribute to the increase of agricultural production, respecting the natural environment and helping to build a more just and fraternal world.

Influenciado por la obra de F. De Sanctis y rechazando cualquier tipo de mentalismo así como el uso excesivo de conceptos abstractos, Benedetto Croce propuso su Filosofía del Espíritu, entendida como una “filosofía de las cosas humanas”. En este sentido, su rechazo al Idealismo metafísico de Hegel-Spaventa-Gentile, principalmente basado en la absoluta unidad del espíritu, le llevó a proponer una necesaria interdependencia de Filosofía e Historia. Abandonando la concepción de la Filosofía en tanto saber puramente mental, para volverla filosofía de las cosas humanas, más cercana al pensar y al hacer de los hombres.

Questo articolo mira ad opporre ad una visione biopolitica del lavoro l’opportunità di una configurazione pedagogica delle organizzazioni nell’era del capitalismo cognitivo ed esperienziale, facendo leva su indicazioni formative finalizzate sia ad evidenziare il contributo propriamente educativo sia a soddisfare congiuntamente l’interesse economico e quello relativo allo sviluppo umano. Nella prima parte, si analizza l’ambivalenza del lavoro odierno e si prospetta il pericolo biopolitico. La seconda parte è dedicata alla dialettica tra soggettivazione e assoggettamento del lavoratore e alla fallibilità dello schema biopolitico. La terza parte, infine, approfondisce la natura pedagogica di un’organizzazione “personale” e si sofferma sulle tematiche del benessere organizzativo e della formazione dell’agency.

A partir de la distribución de frecuencias de tallas de las 14 especies de peces comerciales más importantes del río Apure, se estimaron durante el periodo 2000-2003 los parámetros poblacionales más significativos, así como el índice de desempeño del crecimiento (0) y tasa de explotación (E = F/Z). Las especies analizadas representaron el 83% de la abundancia de las especies comerciales de la zona. Los parámetros de crecimiento se usaron para determinar el estado de los principales recursos pesqueros del río Apure. Los resultados obtenidos indicaron un predominio de valores relativamente bajos de K y altos de L∞, típico de especies longevas. Esto, combinado con los altos valores en las estimaciones de Z y F, implica una alta tasa anual de supervivencia y baja tasa de renovación de la población. Las estimaciones de E para las 14 especies fueron altas E0,1 (0,50-0,94). Los indicadores de sobrepesca para las cuatros especies más abundantes (P. mariae P. tigrinum, M. duriventre y H. littorale), mostraron que al menos tres presentan síntomas de sobrepesca de crecimiento. Se concluye que las 14 especies han sido pescadas severamente y que los resultados obtenidos proporcionan un punto de partida, para el manejo y evaluación de los recursos pesqueros del río Apure.

The article provides a commentary of Arnaut Daniel’s “Lancan son passat li giure”, a moralistic song whose main theme is ‘fals’Amor’ (sensual love). The song holds strong intertextual relations with Raimbaut d’Aurenga’s “Apres mon vers vueilh sempr’ordre”, as is shown primarily by the use of the same rhymes ‘-il’ et ‘-iure’, which do not appear elsewhere in the troubadour corpus. Raimbaut’s song, whose verses 37-54 are interpreted differently by W. T. Pattison, its main editor, also deals with ‘fals’Amor’. But if Raimbaut praises the pleasures of physical love, which is portrayed as an irresistible cajoler, Arnaut condems and refuses it, after having experienced it. In this instance, “Lancan son passat li giure” seems to be a kind of polemic reply to “Apres mon vers”. In Arnaut’s view anyway, ‘fals’Amor’, though criticized, turns out to be the winning pattern of courtly behaviour, given its seductive and persuasive skill, to which it is difficult to resist. The text of Arnaut’song is the one established by M. Eusebi, with substantial modifications.

ABSTRACT Objective: To evaluate morphometric variations of the cervical spine in patients with cervical spondylotic myelopathy (CSM) using dynamic magnetic resonance imaging (MRI) in neutral, flexion and extension positions. Methods: This is a prospective study of patients with CSM secondary to degenerative disease of the cervical spine. The morphometric parameters were evaluated using T2-weighted MRI sequences in the sagittal plane in neutral, flexion and extension position of the neck. The parameters studied were the anterior length of the spinal cord (ALSC), the posterior length of the spinal cord (PLSC), the diameter of the vertebral canal (DVC) and the diameter of the spinal cord (DSC). Results: The ALSC and PLSC were longer in flexion than in extension and neutral position, with statistically significant difference between the flexion and extension position. The DVC and the DSC were greater in flexion than in extension and neutral position, however, there was no statistically significant difference when they were compared in the neutral, flexion and extension positions. Conclusion: Dynamic MRI allows to evaluate morphometric variations in the cervical spinal canal in patients with cervical spondylotic myelopathy.
