Plant growth regulators (PGRs) are described in the literature as having a significant role in securing crop management of modern agriculture in conditions of abiotic and biotic stressors. A joint field experiment was carried out to assess the role of seaweed-based extracts in pear trees and to test the “less for more” theory, which consists of getting more and better agricultural produce using fewer innovative inputs. The trials took place on two production seasons (from March till September 2018–2019) and the selected case study was on a pear orchard (Pyrus communis L. cv. Abate Fètel) in Emilia Romagna (Italy) by Fondazione Navarra and Timac Agro Italia S.p.A. Results demonstrate that, depending on the yearly climate conditions, it was possible to substantially reduce the primary nutrients by 35–46% and total fertilisation units applied by 13% and significantly improve quantitative and qualitative production indicators (average weight of fruits (5%) and total yield (19–55%)). Results also confirm a positive correlation between plant growth regulators and agronomic efficiency of pears which increased between five and nine times compared to the conventional nutrition programme. These outcomes constitute scientific evidence for decision making in farm management.

Shrubs are often used for side slope greening and protection in the urban landscape. Only a few species are commonly used in the European city environment, bestowing upon cities a monotonous appearance. The aim of this 3-year trial, set up at Fondazione Minoprio (Vertemate con Minoprio; Como, Italy), was to evaluate the performance of 25 shrub species grown on a slope during three seasons (2007–09). Moreover, to evaluate the influence of weeds on plant growth and the weeding time, two mulches (biodegradable textile and polypropylene fabric) were used in comparison with bare soil (control). Shrubs were planted in late Spring 2007. To simulate urban conditions, no pruning or disease control were applied. Irrigation was carried out only in the driest periods of the first summer. Plant height and percent cover were measured every 2 months, whereas plant phenology and state of health were recorded weekly. Chlorophyll fluorescence and chlorophyll content were evaluated on two different drought-tolerant species during the third growing season. At the end of the trial shoot biomass was measured and root characteristics (root density and specific root length) were determined. Weeds were removed twice in the first and third years and three times in the second year. Time for weed removal was recorded for each experimental plot. Results show that the highest growth (height and biomass) was detected in mulched plots, probably because of both limited weed competition for water and nutrients and lower water loss by evaporation. Plants grown in bare soil showed higher root density and finer roots compared with mulched plants; this may be explained by the necessity of the plant root system to explore the soil to reach for water. Differences in growth, groundcovering, and root characteristics were observed among species. As a result of higher mulching cost and the poorer root characteristics of mulched plants, bare soil and fast growing shrubs should be used to limit weed competition and assure a satisfactory slope greening and consolidation.

Predictive maintenance is emerging as a promising technique to overcome the limitations of periodic maintenance. It integrates automatic condition monitoring to evaluate the health status of a system or device, with the estimation of Remaining Useful Life (RUL) of its components, in order to schedule maintenance only when really needed, minimizing the downtime of a plant. In this paper, we report our results in evaluating the health conditions of the rotating ball bearings of a critical air pump which is part of the Clean Room industrial facility operating in the Micro-Technologies Laboratory of Fondazione Bruno Kessler. We instrumented such component with vibration and acoustic sensors with the aim of identifying a model of the evolving degradation and estimating the RUL of the bearings. The current dataset covers a period of one month before bearing replacement and about six months after the replacement. The first models, based on regression and particle filter processing of critical spectral components extracted from the sensors, indicate an estimated RUL of about 12 months that is in agreement with the average lifetime based on scheduled maintenance. Subsequent model evolutions have been observed in conjunction with scheduled greasing and periods of lower stress, which resulted in remarkable deviations from the initial degradation trends and in a consequent notable increase of the estimated RUL. Results achieved so far are promising and could be used to extend the temporal distance among periodic maintenance interventions according to the estimated RUL.

Background: This report is based on an independent study carried out by medical professionals of the Fondazione IRCCS Istituto Nazionale dei Tumori (National Cancer Institute) in Milan, Italy, and aimed to assess the incidence of respiratory diseases in a Brazilian community (Piquiá de Baixo, in the city of Açailandia) exposed to extreme air pollution in connection to a local steel manufacturing plant. The study has the objective to contribute to the existing literature on the health risks associated with fine particle pollution (PM2.5) due to steel production with data from Brazil. Methods: The study is based on a cross-sectional sample of the resident population of Piquiá de Baixo age 16 or over consisting of 220 people. We collected data about the health conditions of participant subjects in two ways: a) medical history questionnaires and b) clinical assessment of respiratory function through spirometry testing. The results were evaluated based on comparative studies. Results: According to the spirometric tests performed, 28 % of the sample population suffers from respiratory pathologies (for the most part of restrictive rather than obstructive nature). This incidence rate is between six and two times higher than those reported in similar studies carried out in other countries (which range between 4.6 and 14.5 %). In addition, the incidence rate is also significantly high in light of the fact that our sample population did not include the category of subjects most at risk for pulmonary disorders in connection to air pollution caused by the Piquiá steel processing complex: in other words, men and women employed in the steel mills or in connection with their industrial cycle (as many as 434 Piquiá residents age 16 and over were unable to participate to our study due to “work-related reasons”). Conclusions: In light of the above considerations, we believe that our findings contribute to the existing literature on the correlation between pulmonary disease and air pollution in industrialized areas, while warranting further scientific research on the public health consequences of industrial production in Piquiá de Baixo. In turn, on the ethical plane, we believe that research of this nature strengthens the need to advocate for more severe environmental and health policies aimed at limiting the hazards associated with the steel industry in Piquiá and in similar contexts around the world.

Il lavoro ha lo scopo di analizzare l'istituzione museale da un punto di vista manageriale, con un caso di studio sulla Fondazione Plart di Napoli. L'analisi prende avvio in primis da un punto di vista di evoluzione storica e legislativa dell'istituzione del museo nel corso della storia, sul panorama italiano ed europeo. Tra le diverse tipologie di istituzioni presenti sul nostro territorio vi è un focus particolare sulla figura della fondazione - museo. Si cerca poi di argomentare la categorizzazione del museo da un punto di vista imprenditoriale, secondo le dottrine di economia aziendale più riconosciute. L’attenzione data all’accountability, al valore sociale dell’operato, al servizio offerto in termini di valorizzazione e fruizione ha portato infatti nel corso degli ultimi decenni, oltre che ad un cambiamento sulle ragioni d’esistenza e sui risultati perseguiti di tali istituzioni, una ventata di rivoluzione anche nelle metodologie, negli strumenti e nei linguaggi adottati. Al fine dunque di far fronte alla soddisfazione del diritto sociale alla cultura, si rende necessaria l’applicazione nello specifico anche di tecniche di project management nella gestione, focalizzandosi dunque sull'aspetto progettuale dell'attività museale e in particolare sull'attività espositiva che produce come output principale la mostra. Vi è poi una sezione dedicata all'aspetto di rendicontazione contabile e misurazione dei risultati, punto di partenza per un modello efficace di governance, che ancora oggi non trova soluzioni comuni e riconosciute ma è oggetto di grande dibattito e vede strumenti di applicazione vari. Nell'analisi del caso studio si tenta di applicare gli elementi analizzati alla storia e alla gestione della Fondazione Plart, fondazione familiare che dal 2008 svolge la propria attività con una delle collezioni permanenti di plastiche storiche più originali al mondo, affiancata da una ricca programmazione di mostre, installazioni immersive multimediali, performance, workshop, laboratori e progetti formativi e guarda all’innovazione progettuale come chiave per creare e divulgare esperienze culturali inedite. Il lavoro si conclude con uno sguardo ai principali cambiamenti che la situazione pandemica causata dal virus Sars Covid-19 degli ultimi due anni ha portato a livello di attività e fruizione museale e a come, nel caso studio specifico, si siano trovate risposte a tali cambiamenti.
