Sorption Behavior of Polylactic Acid/Poly(butylene adipate‐co‐terephtalate) Mulching Film Toward Active Substances
No full textPlastic mulching films are often used in agriculture for contributing to reduce water evaporation from the soil, to decrease weed growth and the consequent use of chemicals, and to increase soil temperature at the root level. Petrol-derived polymers, such as low-density polyethylene, can be replaced by biodegradable (bio)polymers in mulching activities, which, after crop harvest, do not need to be removed, but they are very often buried in the soil, thus allowing the farmers to economize on their disposal. A kind of biodegradable mulching film is constituted of a polylactic acid/poly(butylene adipate-co-terephtalate) blend, which is known to be subjected to both enzymatic and photooxidative degradation under aerobic conditions. However, during degradation processes, the mulching films can give rise to microplastic debris, which, in turn, could act as micro-vectors of organic and inorganic pollutants. Understanding the adsorption capability of agricultural mulching films toward active substances commonly used in agricultural activities to enhance crop harvesting could help farmers in choosing the appropriate plastic while trying to reduce environmental pollution. In this study, the adsorption behavior of a commercial polylactic acid/poly(butylene adipate-co-terephtalate) film is investigated, considering azoxystrobin, a widely used organic fungicide, as the active substance
A Deep Deterministic Policy Gradient control algorithm for Automatic Insulin Delivery
No full textThis study investigates the use of Reinforcement Learning (RL) to optimize insulin infusion in Automated Insulin Delivery (AID) systems. The Deep Deterministic Policy Gradient (DDPG) algorithm is evaluated as a potential control strategy and compared to Model Predictive Control (MPC) and PID controllers using a highly realistic in silico simulation model. Simulations for adult Type 1 Diabetes (T1D) patients demonstrate that the DDPG controller effectively reduces hypo- and hyperglycemic episodes and improves glucose stability
Predictive energy scheduling of smart parking infrastructure with solar-powered electric vehicles
No full textThis paper presents a novel model predictive control framework for managing energy flow in smart parking infrastructures with renewable energy facilities, electric vehicles, and solar-powered electric vehicles. The proposed control framework minimizes the energy costs for the parking lot operators, ensuring the user-defined charge levels for vehicles at departure, and protecting the charging infrastructure during operation. Field validation on Lonsdale Street, Melbourne (Australia)—using real data on vehicle behavior, solar irradiance, and energy prices—shows significant grid load reduction even with partial solar production. Compared to a rule-based strategy, the MPC approach reduces operational costs by 15.32% and energy demand by 6.12%. Lastly, we show that the proposed framework is robust under forecast uncertainty, supporting its practical deployment in dynamic real-world environments
Modeling and Simulation of Electric Vehicles Charging Services by a Time Colored Petri Net Framework
Full text linkThe transport sector is responsible for about 60% of emissions in the atmosphere due to the exhaust-polluting gases of internal combustion engine (ICE) vehicles. An effective solution to this issue is the electrification of the transport means, which can significantly reduce pollution, especially in urban areas. Apart from the necessary technological advancements that must improve the battery performances, the diffusion of electric vehicles (EVs) must be further supported and facilitated by new dedicated services and tools for electric vehicle users and operators aiming at improving the travel and charging experience. To this goal, this paper proposes new models based on Timed Colored Petri Nets (TCPN) to simulate and manage the charge demand of the EV fleet. At first, the proposed tool must take into account the charging requests from different EV drivers with different charging need located in different geographical areas. This is possible by knowing input data such as EV current location, battery data, charge points (CPs) availability, and compatibility. In particular, EV drivers are simulated when finding and booking the preferred charge option according to the available infrastructure in the area of interest and the CPs tariff and power rate. The proposed TCPN is designed to model the multi-user charging demand in specific geographic areas, and it is evaluated in several scenarios of a case study to measure its performance in serving multiple EV users
Regenerable chitosan-biochar-TiO2 composite sponges for hazardous pollutants removal from water: The case of carbamazepine
No full textWater pollution is a significant worldwide problem, and research studies in this field are still in progress to find strategies for removing pollutants from water. Among the others, adsorption process seems to exhibit several advantages, especially when biomasses are in use. This work proposes biochar from olive pomace pyrolysis for adsorbing contaminants from water, in synergistic combination with TiO2, for constituting water-stable and recyclable composite chitosan-based sponges. The photocatalyst and the biochar were embedded into the polymeric chitosan foam network. So, the employed materials were characterized from a physical and chemical point of view, revealing the nature of porous adsorbent substrates having irregular surfaces useful for sequestrating pollutants. UV–Vis spectroscopy was used to monitor the amount of pollutants in water, and the maximum adsorption capacities were calculated. Carbamazepine, was selected as a model contaminant to study the process features under different working conditions. A comparison with the removal of a textile dye was also performed to unveil the mechanism of adsorption. After the pollutant adsorption, its complete desorption was obtained, proposing a way to reuse the adsorbent material, lowering the environmental impact. An alternative to regenerate the adsorbent was also studied by exploiting the photocatalytic role of TiO2
Another way to valorize by-products: Coffee silver skin for removing the antibiotic norfloxacin from water
No full textCoffee silver skin is reported as an adsorbent for treating water from Contaminants of Emerging Concern, focusing on the removal of Norfloxacin, an antibiotic. According to the sustainability principles, coffee silver skin before its use was washed with water, lowering the associated costs and the whole environmental impact. The proposed adsorbent was characterized by adopting synergistically ATR-FTIR, SEM, and TG techniques, inferring its main features before and after the pollutant removal. Specifically, the presence of the latter in water was monitored by using UV-Vis spectroscopy. Several experimental conditions were explored during the adsorption, and the roles of ionic strength, pH, adsorbent/pollutant amounts, and temperature were investigated. The thermodynamics, adsorption isotherms, and kinetics were also studied, revealing that the process was spontaneous and occurred on heterogeneous skin surfaces forming a pollutant multilayer, joining a maximum adsorption capacity of 50mg×g-1. Interestingly, the pH values and ionic strength strongly affected the process, denoting the main presence of reversible electrostatic interaction between the pollutant and coffee silver skin. Indeed, the recycling of the proposed adsorbent was demonstrated by adopting safe and green conditions of work in the presence of diluted salt solutions or water at 50°C, also recovering the pollutant. So, this paper has the aim to present, for the first time, the kinetics and thermodynamics of an adsorption process referred to the removal of an emerging pollutant from water by using coffee silver skin, avoiding hard working conditions to pre-treat the material before its use, thus proposing an alternative way to reuse this by-product as recyclable adsorbent
Iron Oxides on Waste Steel Slags as Catalyst for the Transfer Hydrogenation of Nitrobenzene Using iso‐Propanol as Hydrogen Source
No full textIron oxide-based catalysts have been widely investigated due to their high catalytic activity and operational availability. However, in the perspective of commercial application, performance and cost are two crucial parameters for the development of catalysts. To reduce the cost, it is possible to use industrial wastes, such as steel slags, as effective support for iron oxide catalysts, which are also able to assist the catalytically active sites during their performances. Currently, steel slags are mainly used as building materials, nevertheless, sustainable reuse technologies are still desirable. Herein, the synthesis and characterization of several materials constituted of iron oxides onto steel slags in different mass ratio are reported. Their catalytic activity is also investigated in the reduction of nitrobenzene using iso-propanol as the hydrogen source in the absence of any added base

No full textIntroduction: A recent clinical trial underscored the importance of repeated minimal residual disease (MRD) monitoring by RQ-PCR in Mantle Cell Lymphoma (MCL), a disease with initially high response rates but both early and late relapses [Ferrero Blood 2022]. However, MRD kinetics are complex, posing interpretation and clinical application challenges
Spazi effimeri per il commercio: i progetti di Marino Lopopolo per la «grande Bari»
No full textLa presente tesi indaga l’architettura dello spazio commerciale in Italia fra le due guerre, assumendo l’opera di Marino Lopopolo (1905-1980) quale caso emblematico per comprendere le dinamiche di modernizzazione del tessuto urbano barese nel quadro della «grande Bari» fascista. Muovendo dall’ipotesi che il negozio costituisca un banco di prova privilegiato per l’elaborazione di nuovi linguaggi e tecniche costruttive, la ricerca ricostruisce criticamente il ruolo di tali dispositivi nella trasformazione dell’immagine urbana e nell’affermazione di istanze razionaliste e d’avanguardia.
Il lavoro si fonda sul riordino sistematico dell’Archivio Lopopolo – composto da 35 faldoni e 371 fascicoli – e su un’ampia ricognizione bibliografica. L’impianto metodologico si articola intorno a due repertori di schede complementari. Le schede interpretative, di natura critico-comparativa – elaborate su una griglia di criteri analitici – sono state redatte per l’analisi dei casi studio: cinque esempi nazionali “canonici” (Parker, Olivetti, Galtrucco, Motta, Calze Fama) e, con lo stesso modello, cinque interventi di Lopopolo (Giove I, Scannicchio, Giove III, Giove II, Ciccolella).
Le schede di analisi, invece, – di taglio catalografico – documentano i negozi di Lopopolo censiti in archivio, registrandone cronologia, committenza, stato di conservazione dei documenti, corredo grafico-fotografico, con un grado uniforme di dettaglio.
Questa duplice struttura ha consentito non solo il confronto interno tra i casi studio, ma anche di estenderne la comparazione a opere coeve di altri architetti italiani, evidenziando convergenze e divergenze rispetto alle emergenti istanze comunicative della modernità. Dall’analisi incrociata delle schede interpretative è inoltre emersa una tassonomia di categorie tipologiche – vetrina a tutta luce, soglia arretrata come tasca espositiva, involucro trasparente, uso di soluzioni leggere – che, definite a partire dai casi nazionali, si è rivelata funzionale ad ascrivere e leggere criticamente anche i progetti di Lopopolo dentro la stessa matrice disciplinare, verificandone invarianti tipologiche e specificità linguistiche.
Sinossi diagrammatiche e ridisegni critici supportano la lettura morfologica dei fronti commerciali, mentre l’esame urbanistico e socio-economico degli interventi dimostra come la trasparenza della soglia, l’impiego di materiali innovativi e la sperimentazione tecnologica abbiano contribuito a ridefinire la percezione dello spazio pubblico, trasformando il commercio in un’esperienza rappresentativa della modernità.
Organizzata in cinque capitoli seguiti da apparati bibliografici e inventariali, la tesi restituisce una tassonomia interpretativa dello spazio commerciale fra le due guerre, chiarendo il contributo dei negozi quali dispositivi di mediazione fra città storica e città moderna. L’insieme delle fonti analizzate riafferma infine il valore documentario dell’Archivio Lopopolo come risorsa scientifica e patrimonio culturale.This dissertation investigates the architecture of commercial space in Italy during the inter-war years, taking the work of Marino Lopopolo (1905–1980) as an emblematic case through which to understand the dynamics of urban modernisation in Bari within the Fascist project for a “Greater Bari.” Proceeding from the hypothesis that the retail establishment constitutes a privileged testing ground for new design languages and construction techniques, the study critically reconstructs the role of such devices in reshaping the urban image and in promoting rationalist and avant-garde ambitions.
The research rests on the systematic re-ordering of the Lopopolo Archive—comprising thirty-five boxes and 371 dossiers—and on an extensive bibliographical survey. The methodological framework is organised around two complementary sets of records. Interpretative records, critical-comparative in nature and compiled according to an analytical grid of criteria, were prepared for ten case studies: five canonical national examples (Parker, Olivetti, Galtrucco, Motta, Calze Fama) and, following the same template, five projects by Lopopolo (Giove I, Scannicchio, Giove III, Giove II, Ciccolella). Analytical records, catalogue-oriented in scope, document every Lopopolo shop identified in the archive, registering chronology, patronage, state of conservation of the documents, and the associated graphic-photographic corpus with a uniform level of detail.
This dual structure not only enabled internal comparison among the case studies but also extended the analysis to contemporary works by other Italian architects, thereby highlighting convergences and divergences in relation to emerging communicative imperatives of modernity. Cross-analysis of the interpretative records yielded a taxonomy of typological categories—full-height glazed façade, recessed threshold as display alcove, transparent envelope, and the use of lightweight solutions. Defined originally from the national cases, this taxonomy proved effective for situating and critically reading Lopopolo’s projects within the same disciplinary matrix, revealing both typological invariants and linguistic specificities.
Diagrammatic synopses and critical redrawing support the morphological reading of the commercial fronts, while urbanistic and socio-economic examination demonstrates how threshold transparency, innovative materials, and technological experimentation contributed to redefining perceptions of public space, transforming commerce into an experience emblematic of modernity.
Structured into five chapters followed by bibliographic and inventory apparatus, the thesis offers an interpretative taxonomy of inter-war commercial space, clarifying the shop’s role as a mediating device between the historic and the modern city. The corpus of sources analysed ultimately reaffirms the documentary value of the Lopopolo Archive as both a scientific resource and a cultural asset
