Il revisionismo borghese nelle case per gli statali di inizio Novecento a Potenza
No full textIl presente contributo indaga il caso paradigmatico delle residenze INCIS realizzate agli albori del Ventennio
fascista nella città di Potenza, evidenziando il dualismo tra innovazione e passatismo nell’ambito
dell’architettura italiana del primo Novecento. In particolare, si analizzano le dinamiche sociali e formali
che hanno guidato la costruzione di una nuova edilizia borghese per il ceto impiegatizio statale, in un
contesto urbano periferico, sebbene caratterizzato da profonde trasformazioni. L’approccio adottato
integra l’analisi storico-architettonica con una riflessione sul ruolo del disegno come pratica descrittiva,
critica e narrativa, che attraverso l’elaborazione grafica ed il confronto con il materiale documentario
d’epoca, propone una lettura stratificata delle preesistenze come dispositivo di memoria e veicolo di
un linguaggio ideologico. In tale prospettiva, le rappresentazioni prodotte divengono forme visuali di
racconto, capaci di restituire il valore culturale di un patrimonio costruito spesso trascurato, rafforzando
il legame tra lo spazio e la narrazione identitaria
Eco-Sustainable management of weeds and phytopathogens using Achillea millefolium essential oil
No full textThe increasing concern over the environmental impact of synthetic herbicides has led to growing interest in plant-based alternatives. This study investigates the phytotoxic and antimicrobial properties of Achillea millefolium essential oil (EO), collected in Agerola, Italy. The chemical composition analysis conducted by GC-MS identified 69 compounds, with oxygenated monoterpenes being the dominant group, including borneol (12 %), camphor (11.5 %), and 1,8-cineole (8.9 %). The phytotoxic activity was evaluated by analyzing both the root and hypocotyl elongation, as well as the number of germinated seeds of Sinapis arvenis, Lolium multiflorum, Raphanus sativus, and Hordeum vulgare. The EO demonstrated significant phytotoxic effects on seed germination and seedling growth, particularly against S. arvensis. Additionally, a possible inhibitory activity on the α-amylase enzyme extracted from germinating seeds was evaluated as a potential mechanism of action. The EO also exhibited antimicrobial activity against Xanthomonas campestris and Penicillium italicum. These findings highlight the potential of A. millefolium EO as a natural herbicide and antimicrobial agent, offering an eco-friendly alternative for sustainable agriculture. Furthermore, the eco-friendliness of this EO was evaluated using a lethality test of brine shrimp, with no toxicity observed on Artemia salina, suggesting its potential as a safe bioherbicide

Get PDFResilience‐based assessment of seismic risk by investigating the socioeconomic and structural earthquake engineering factors
No full textVarious impacts of earthquakes in different countries with distinct social and economic conditions (SEC) indicate that seismic
risk is affected by SEC. It is also well accepted that seismic risk depends, through the quality of structures in built environments,
on structural earthquake engineering (SEE) actions. The consequences of earthquakes correspondingly affect SEC
and the status of SEE, at least by attracting attention to engineering solutions that aim to overcome the continuing challenge
of safety against earthquakes. SEC and SEE are therefore two fundamental dimensions of sustainable seismic resilience,
which is the key earthquake disaster risk reduction strategy. This paper explores resilience-related interactions between SEC
and SEE to help humanity more effectively cope with the earthquake challenge. Ten earthquake-prone countries are selected
as case studies. SEC are statistically evaluated based on some related criteria, including migration rate and monetary flow.
The status of SEE is thoroughly investigated by considering both direct and indirect factors. The application of seismic
isolation, the well-known SEE solution, and completeness of open street map projects are the studied direct factors. Death
tolls and economic losses are considered as the indirect factors relating to inappropriate and inadequate preparedness against
earthquakes. Interactions between SEC and SEE are discussed through detailed comparisons of the studied measures, and
seismic risk is assessed based on resilience. It is shown that disaster risk reduction essentially requires economic support
by the government and this can occur if the society is aware of the need for implementing effective SEE techniques in civil
engineering practice
Integration studies of a positive neutral beam injector system into the design of a volumetric neutron source
No full textA feasibility study regarding a volumetric neutron source (VNS) is presently conducted in the EUROfusion Consortium. The VNS uses Positive Neutral Beam Injection (P-NBI) for plasma heating, current drive and particularly to drive beam-target fusion, aiming for a high neutron production (≈0.5 MW/m2 neutron wall load in the equatorial plane). P-NBI is a reliable auxiliary heating system, widely employed in plasma devices such as ASDEX Upgrade (AUG), W7-X and JT60-SA. The paper describes the integration of the P-NBI system into the design of the VNS. This includes the neutral beam (NB) duct from the torus vacuum vessel to the NBI box with the gate valves, the space requirements of the NB injectors in the building as well as the connections for cooling water, cryo-supplies, electrical high voltage and radio frequency (RF) cable connections. Since the VNS is a nuclear machine with lifetime doses significantly exceeding those of ITER, the requirements for remote maintenance (RM) are very different from any existing NBI design. The RM concept and the RM sequences will be discussed. Neutronics studies for the NB duct were performed and design iterations undertaken to assure that neutron heating and lifetime fluences remain below limits at the superconducting toroidal and poloidal field coils adjacent to the NB duct. The work considers the return of experience from AUG, ITER and some other fusion experimental machines in operation, under construction or in conceptual design such as DEMO
Natural Bioactive Compounds from Orchard Biomass Waste and Cosmetic Applications
Get PDFAntioxidants are crucial in counteracting the impact of free radicals, thereby preventing cell damage. Extracts from orange, apricot, and olive tree pruning, classified as by-products according to environmental laws, underwent examination of their antioxidant properties. In the present investigation, data on the antioxidant activity of extracts of these tree by-products were used to calculate the relative antioxidant capacity index (RACI). The latter made it possible to identify Apricot bark maceration extract as having the highest antioxidant index. Further analysis through UHPLC-MS enabled the identification of compounds known for their antioxidant activity, including catechin, epicatechin, and others. Cytotoxicity assays conducted on human hepatocellular carcinoma cell lines (HepG2) confirmed the safety of the chosen extract for cosmetic applications. The extract was then used to formulate a cosmetic cream, which subsequently underwent quality control and proved to be stable, of good consistency, and free of pathogens. The results show that developing a sustainable cosmetic cream prototype is a promising step toward realizing an environmentally friendly product in the circular economy context

No full textPortable NIR Spectroscopy Combined with Machine Learning for Kiwi Ripeness Classification: An Approach to Precision Farming
Get PDFThis study aims to evaluate and classify the ripening stages of yellow-fleshed kiwifruit by integrating spectral and physicochemical data collected from the pre-harvest phase through 60 days of storage. A portable near-infrared (NIR) spectrometer (900–1700 nm) was used to develop predictive models for soluble solids content (SSC) and firmness (FF), testing multiple preprocessing methods within a Partial Least Squares Regression (PLSR) framework. SNV preprocessing achieved the best predictions for FF (R2P = 0.74, RMSEP = 12.342 ± 0.274 N), while the Raw-PLS model showed optimal performance for SSC (R2P = 0.93, RMSEP = 1.142 ± 0.022°Brix). SSC was more robustly predicted than FF, as reflected by RPD values of 2.6 and 1.7, respectively. For ripening stage classification, an Artificial Neural Network (ANN) outperformed other models, correctly classifying 97.8% of samples (R2 = 0.95, RMSE = 0.08, MAE = 0.03). These results demonstrate the potential of combining NIR spectroscopy with AI techniques for non-destructive quality assessment and accurate ripeness discrimination. The integration of regression and classification models further supports the development of intelligent decision-support systems to optimize harvest timing and postharvest handling
