CONSERVATION 4.0. POSSIBLE GUIDLINES FOR STANDARDISING THE DOCUMENTAL PROCESS FOR ARTISTIC HERITAGE

Abstract. The contribution addresses the definition of a new standardised method for the documentation of the restoration process. In the frame of a conservation laboratory open to the public, the research drew up the guidelines for a documental and representative methods discussing the definition of a contemporary conservation praxis facing with digital technologies.The research stems from a restoration of a Polyptych, Madonna con Bambino, Santi e Apostoli by Vittore Crivelli, damaged by earthquake of 2016 and temporarily showcased at Pinacoteca of San Domenico in Fano (PU). The public could visit the workplace set up and use the experimental informative system created from conservative data and results of intervention. To do this, the general process of documentation has progressed in strong synergy with restoration work. Thanks to the collaboration between experts, the project has established a set of priorities in order to capitalise the global results and better communicate each phase of intervention.The content of the study focuses on identifying guidelines that would form a possible framework for documentation useful for conservation of artistic heritage.The standard workflow presented in the paper may potentially influence the theory of conservation as well as the practice. Developing a new approach to heritage, the study aims at bringing digital strategies into the field of conservation in order to propose the new idea of Conservation 4.0

A MULTIDISCIPLINARY DOCUMENTAL REPRESENTATION METHOD FOR KINETIC AND ENVIRONMENTAL ART

Abstract. The contribution addresses the definition of a new collaborative documental method for designing and managing the different phases of conservation of kinetic-programmed art. Our approach consists of developing a new representative model that includes both mechanical parts and spatial characteristics. The research stems from a specific case-study, Ambiente – Strutturazione a parametri virtuali (1969) by Gabriele Devecchi, permanently displayed at Museo del '900 in Milan since 2010. Starting from the dimensional and technical data, we obtained a graphical model of lamps 2D and 3D. They were enriched by a detailed abacus describing all the elements and by specific maps capturing all the phases of regular and extraordinary maintenance underwent by the environment. The second part was carried out with a report about physical motion. The goal has been representing speed and geometry of the movement inside the space. By merging the first part of the documenting process and the second one we've got a graphic digital model including information about the individual parts of the installation and their mechanical interaction. The third and last step is ongoing and tackles the challenge of using virtual technologies for the description of the whole environment. Thanks to a collaboration between technicians and theoretic scholars, we attempted to match the study of the physical motion and all data about the structural parts with the careful consideration of historical-artistic and perception-related features. The work led to the conclusion that a virtual, immersive reproduction of the environment is not enough for deeply understanding the experience enjoyed by users inside it, because it misses the embodied perception activated by the artwork. For this reason, this study may be considered as a step in a broader research path about documentation of complex environmental, immersive, kinetic works of art.</p

Microestrutura da fibra alimentar do albedo de laranja: um estudo por técnicas físicas e análise de imagens.

As fibras alimentares são consumidas naturalmente em cereais, frutas e hortaliças, mas também são adicionadas na forma concentrada em alimentos processados. Diferentes fontes de fibras têm diferentes estruturas e composições químicas, que irão definir a sua finalidade nutricional ou tecnológica. Este trabalho tem como objetivo a caracterização de fibra alimentar do albedo da laranja submetida a dois métodos de secagem (liofilização e convencional) e divididas por intervalos granulométricos. Para as determinações de densidade, área superficial, porosidade e distribuição de tamanho de poro, utilizaram-se técnicas clássicas da tecnologia de sistema particulado e foram comparadas com imagens de microscopia eletrônica de varredura. Os resultados apontaram que o método de secagem é o que mais influenciou na redução do volume de poros do material, também visualizado nas características microestruturais reveladas pela análise de imagem. O intervalo granulométrico da fibra particulada apresentou-se inversamente proporcional à densidade e à área superficial específica do material. A fibra alimentar do albedo da laranja apresentou características estruturais que permitem a diversificação de novos produtos alimentícios com alto valor nutritivo e comercial

A parametric approach for evaluating the stability of agricultural tractors using implements during side-slope activities

A methodological approach for evaluating a priori the stability of agricultural vehicles equipped with different mounted implements and operating on sloping hillsides is shown here. It uses a Matlab simulator in its first phase and, subsequently, the Response Surface Modelling (RSM) to evaluate the coefficients of a set of regression equations able to account for the Type-I and Type-II stability of the whole vehicle (tractor + implement with known dimensions and mass). The regression equations can give reliable punctual numeric estimations of the minimum value of the Roll Stability Index (RSI) and can verify the existence of a Type-I equilibrium without the need of using the simulator or knowing any detail about the model implemented in it. The same equations can also be used to generate many intuitive graphs (\u201cequilibrium maps\u201d) useful to verify quickly the possible overturning of the vehicle. A case-study concerning a 4-wheel drive articulated tractor is then presented to show the potential of the approach and how using its tools. The tractor has been studied in three scenarios, differing on where the implement has to be connected to the tractor (1: frontally; 2: frontally-laterally; 3: in the back). After performing a series of simulations, a set of polynomial models (with 6 independent variables) has been created and verified. Then, these models were used, together with the related equilibrium maps, to predict the stability of 8 implements for scenario 1, 7 implements for scenario 2, and 3 implements for scenario 3, evidencing in particular the danger of using a lateral shredder with a mass greater than 245 kg. The proposed approach and its main outcomes (i.e., the regression equations and the equilibrium maps) can give an effective contribution to the preventive safety of the tractor driver, so it could be useful to integrate it in the homologation procedures for every agricultural vehicle and to include the resulting documentation within the tractor logbook

Clinical and Immuno-Pathology Aspects of Canine Demodicosis

Canine demodicosis is a common and often severe dermatopathy of dogs. It is caused mainly by Demodex canis, a parasitic mite of the skin of dogs of the genus Demodex, of the order Acarina and family Demodecidae. This study is aimed to review the clinical-pathological presentation of canine demodicosis and the cytokine-mediated immune response to the cutaneous density of the mite. Only dogs with a defective immune response will present the disease, whether localised or generalised. Microscopically, the dermal inflammatory response is similar among dogs. Localised and generalised demodicosis and pyoderma associated with a high cutaneous density of mites are factors associated with aggravation of lesions in both forms of disease presentation. In addition, the participation of cytokines has been investigated in the induction of the immune response in the different forms of the disease. Although different research groups have invested in studies aimed at elucidating the canine demodicosis pathogenesis, there is still insufficient data to understand the important role of the host immune system in triggering clinical signs and the reproductive management is still an effective preventive method for disease perpetuation

La documentazione per una conservazione "sostenibile" come il digital può integrare il lavoro dei restauratori

I beni culturali sono spesso definiti i giacimenti inesauribili da cui l’Italia attinge. I cittadini che ogni giorno vivono il nostro patrimonio gli assegnano un significato collettivo e personale, caratterizzandolo di valori che si creano e si rigenerano nel tempo . Nella convinzione che questi valori siano la personalità e la qualità di una cittadinanza evoluta e contemporanea, la conservazione dei beni culturali è necessariamente argomento che interessa tutti, esperti e non. Il grande tema della salvaguardia del patrimonio diventa così argomento dell’intera società, che deve quotidianamente essere informata sul suo stato di salute, in un’ottica di partecipazione culturale e sociale a più livelli. Il mondo della conservazione deve integrare alle sue pratiche scientificamente consolidate l’approccio digitale, che prevede la progettazione di nuovi percorsi supportati dall’uso di nuovi strumenti. L’obiettivo ultimo si auspica sia la definizione di un modello documentale digitale che possa contenere al suo interno informazioni tecniche specifiche e dal quale partire per elaborare una comunicazione diretta e di immediata lettura. Il processo di restauro adempie così al suo scopo originale, di ri-accessibilità dell’arte e democratizzazione dei messaggi in essa contenuti

Prospects for detecting Gamma-Ray Bursts with the Cherenkov Telescope Array

The Large Area Telescope (LAT) on the Fermi gamma-ray satellite telescope observes Gamma-Ray Bursts (GRBs) at energies above 100 MeV. Thanks to a new detection algorithm and a new event reconstruction, it is expected to publish a catalogue with more than 100 GRBs. This work aims at revising the prospects for GRB alerts with the Cherenkov Telescope Array (CTA) based on the new LAT results. We start by considering the simulation of the observations with the full CTA of two extremely bright events, the long GRB 130427A and the short GRB 090510; then we investigate how these GRBs would be observed by different subsamples of the array pointing to different directions, adopting the \u201ccoupled divergent\u201d mode

Computer Simulation and Fire Drill in an Educational Building

Despite the evolution of computational models for evacuation simulations, there's still some doubt if they can generate accurate results. The objective is to analyze and compare the evacuation times of a fire drill and a computer simulation in an educational building. The method consisted of a fire drill with prior notice of a 4-floor building with classrooms in a public university. A computational model was developed for the same building and population using the evacuation simulation software Pathfinder. The results were that the evacuation times observed in the computer simulation were slightly lower than the times of the fire drill because people covered smaller distances due to the random distribution performed by the Pathfinder software and because in the drill some time was spent for the start of the movement toward the exit, which was estimated at around 30 seconds, while the software was configured for a pre-movement time equal to zero. The use of the computer simulation, therefore, proved to be an effective solution to replace the fire drill, since it allows for the identification of design failures and for the simulation of different scenarios in less time and without the need to mobilize people
