On the approximation of SBV functions
No full textIn this paper we deal with the approximation of SBV functions in the strong BV topology. In particular, we provide three approximation results. The first one, Theorem A, concerns general SBV functions; the second one, Theorem B, concerns SBV functions with absolutely continuous part of the gradient in L^p, p>1; and the third one, Theorem C, concerns SBVp functions, that is, those SBV functions for which not only the absolutely continuous part of the gradient is in L^p, but also the jump set has finite H^{N-1}-measure. The last result generalizes the previously known approximation theorems for SBVp functions, see [A. Braides, V. Chiadò-Piat, J. Math. Pures Appl., 1996] and [G. Cortesani, R. Toader, Nonlinear Anal., 1999]. As we discuss, the first and the third result are sharp. We conclude with a simple application of our results
Anthropogenic impact in the Vesuvius National Park: effect of dust accumulation on leaves of Centranthus ruber (L.) DC. subsp. ruber
No full textIn Mediterranean ecosystems, the anthropogenic impact makes the preservation of plant biodiversity critical.
Indeed, human pressure can be responsible for the depletion of vascular flora and the reduction in biomass
production. Within the Campania region, some areas of the Vesuvius National Park are particularly exposed
to the anthropogenic impact due to seasonal tourism. As a matter of fact, during spring and summer, a
considerable amount of tourists pass through the Park areas, also with vehicles, thus causing the formation of
dust clouds which are deposited over the vegetation close to the paths (Fig. 1).
The main aim of this study is to analyse whether the deposition of dust on the leaf lamina of Centranthus
ruber (L.) DC. subsp. ruber (Caprifoliaceae) plants can induce changes in leaf anatomy and in the efficiency
of photosynthetic apparatus. The study was conducted on C. ruber plants growing at three sites, similar for
environmental conditions and species composition. For each site two different sub-areas were considered: 1)
the first, located along the side of the road, where a high deposition of dust (HD) was recorded on leaves,
and 2) the second, placed at least five meters far from the path, where plants were subjected to a very low
deposition of dust as control (LD). The amount of deposited dust was quantified at the study sites, in
different periods of the year, characterized by different tourism access (spring-summer-autumn). Being C.
ruber widespread throughout all the area of Vesuvius National park, it was chosen as an environmental
indicator, making possible to evaluate the potential negative effects of the dust deposition on both anatomical
and ecophysiological features. Functional traits in leaf lamina (e.g. stomatal size and frequency, percent of
intercellular spaces in mesophyll) were quantified through light microscopy on fully-expanded leaves
collected in summer (Fig. 2). Ecophysiological traits (chlorophyll a emission, photosynthetic pigment
concentration and leaf traits) were carried out as well on fully expanded leaves, during spring and summer.
Our results showed that HD leaves enhanced a pool of anatomical and photochemical traits allowing to
overcome the effect of dust. Dust-induced changes in photosynthetic pigment content and stomata features
were recorded. The overall analysis suggests that the greater amount of dust raised from the paths, shielded
the leaf lamina: indeed leaves developing near the paths formed morphoanatomical traits as “shade leaves”.
We infer that the phenomenon of dust deposition acts as a screen on leaves thus shading the photosynthetic
apparatus from the light excess during summer. Although this phenomenon is positive for the optimization of
C. ruber growth in these specific sites, the response of other species must be analysed to evaluate possible
dust-induced vegetation dynamics consequent to possible species-specific adaptive capability
Seismic Vulnerability Reduction for Historical Buildings with Non-Invasive Subsoil Treatments: The Case Study of the Mosaics Palace at Herculaneum
No full textThe possibility to reduce the seismic vulnerability of historical buildings through subsoil treatments aimed to modify the seismic site response is a recent advancement in earthquake engineering: the paper presents the case study of the Mosaics Palace, located close to the archeological site of Herculaneum which is about 10 km south of Naples. The study was developed through uncoupled dynamic analysis of the seismic site response and of the masonry structure.
All the available information on the subsoil were collected and integrated with on-purpose in situ tests; a 1-D subsoil model was adopted for linear equivalent seismic response analysis. Several hypotheses of soil treatments, spanning from soft to stiff grouted layers, were taken into account.
On the other hand, the capacity of the structure was defined by a pushover analysis and compared to the seismic demand for each soil treatment option, allowing for a final assessment of the effectiveness of the proposed technology on the building performance
Cognitive profile and 18F-fluorodeoxyglucose PET study in LRRK2-related Parkinson's disease
No full textLRRK2 gene mutations underlie the most common mendelian form of Parkinson's Disease (PD), designated PARK8, that shows clinical features similar to those in idiopathic PD (IPD). We assessed the cognitive functions and the cerebral metabolism measured with 18F-fluorodeoxyglucose (FDG)-PET in PARK8 patients compared with IPD
Trasferimento di giochi di ruolo psico-pedagogici in contesti digitali
No full textIn materia di competenze chiave per l’educazione, la formazione e l’apprendimento permanente, l’attenzione si è spostata dalle hard skill, ovvero competenze relative a un determinato dominio di conoscenza, alle soft skill e numerose sono le ricerche empiriche che hanno accertato l’efficacia del role-playing in ambito formativo. Anche il mondo dell’e-learning si sta progressivamente avvicinando a tale ambito. Ci riferiamo in modo specifico alle simulazioni per l’apprendimento basate sulle tecniche del role-play per lo sviluppo di videogiochi che riproducono ambienti virtuali grafici per l’apprendimento delle soft skill: competenze trasversali espressione di un continuum rispetto alle sfere della vita personale, professionale e sociale (es. comunicazione, leadership, negoziazione). In un recente lavoro edito da Springer (Dell’Aquila et al., 2017) abbiamo presentato e proposto una serie di esperienze per l’utilizzo di nuove tecnologie all’interno di contesti educativi e per la formazione professionale delle soft skill, personalizzate per una vasta comunità di attori sociali, istituzionali e non, così da facilitare la trasferibilità dei comportamenti e delle competenze apprese nella realtà quotidiana. Tale esperienza è stata da un lato di impulso per la realizzazione di un MOOC che renda fruibile l’esperienza di tali applicazioni alla vasta comunità di professionisti quali pedagogisti, psicologi, formatori che possono avvalersi di attività per implementare percorsi personalizzati di apprendimento. Dall’altro ha condotto allo sviluppo di un nuovo progetto ACCORD che si pone come obiettivo la realizzazione di un serious game per la risoluzione di conflitti in ambito interculturale per gli insegnanti che consentirà verificarne tanto l’efficacia formativa quanto metodologica con una diversa competenza relazionale e in un diverso contesto di applicazione
Arquitecturas de emergencia y continuidad social
No full textLos procesos de reconstrucción posteriores a catástrofes deben tender, con la mayor celeridad posible, a proporcionar un primer refugio así como también a iniciar la reconstrucción de la dimensión comunitaria de las áreas destruidas.
Muchas catástrofes han demostrado que una reconstrucción limitada a proveer un simple refugio, puede tener efectos extremadamente negativos en el desarrollo de una comunidad.
Una catástrofe no destruye solo el patrimonio arquitectónico sino que además altera un patrimonio social construido a través de los siglos.
Especialmente las comunidades pequeñas están sujetas, por esto, al riesgo de su completa e irreversible desaparición.
Un planteamiento que no tenga en cuenta, debido a las urgencias, la necesidad de actuar no solo sobre las unidades habitacionales, sino también sobre el patrimonio social, podría afectar dramáticamente al desarrollo de la comunidad afectada.
Si observamos la experiencia italiana, uno de los aspectos más traumáticos posteriores a los últimos sismos, ha sido el rechazo de parte de la población afectada hacia las arquitecturas temporales, containers, etc., en los cuales el concepto de vida comunitaria era inexistente.
Este sentimiento de desapego ha registrado episodios extremos, sobretodo por parte de la población anciana, con sentimientos de confusión ligado a la pérdida repentina de arraigo a la propia comunidad.
Por tanto, la reconstrucción de la comunidad junto con las unidades habitacionales se antoja una necesidad que la estrategia proyectual debe reflejar para dar una respuesta rápida, adecuada y económicamente sostenible.
Este texto desea describir algunas hipótesis desarrolladas en el seno de la investigación universitaria, de soluciones arquitectónicas ante situaciones de emergencia que pretenden, con una acción de transformación social, generar un nuevo tejido comunitario, similar al precedente. Existen algunos factores comunes sobre los cuales se ha desarrollado un proceso proyectual que ha sido aplicado a diversas realidades geográficas, a diferentes contextos territoriales.
Un primer aspecto es la integración de funciones, de modo que los nuevos módulos habitacionales deben ser, más que elementos autistas, una estructura integrada que estimule las relaciones sociales y que produzca beneficios para sus habitantes.
En una comunidad cada persona desempeña un papel, el cual debe ser recuperado inmediatamente.
Esto significa que los módulos habitacionales deben proveer espacios para oficinas, laboratorios artesanales, negocios, así como también pequeños espacios para huertas que garanticen un autoabastecimiento alimentario.
La dimensión social debe ser acentuada por el modo de agregación de las unidades habitables, por el modo de generar espacios colectivos en donde la comunidad pueda reencontrarse y reconstruirse.
Este planteamiento debe ir acompañado de aquellas estrategias que supongan una reducción de costes, fundamentalmente simplificando los procesos constructivos mediante la autoconstrucción. La autoconstrucción permite un abaratamiento de costes así como la participación de la comunidad local en la regeneración posterior a una catástrofe, lo cual favorece el desarrollo de una nueva cohesión social.
Esto significa que se debe evitar que la población afectada por una catástrofe viva la reconstrucción como una experiencia traumática, y que, asimismo, pueda contribuir a conservar y evolucionar la memoria del patrimonio cultural tangible de la comunidad
