The "Six Characters" of Giuseppe Fava's Delirio (1980)
No full textCare lettrici & Cari lettori,
we are thrilled to present you with Volume 36 of PSA - The Journal oh the Pirandello Society of America. This year's issue features a striking cover image of a scene from A Green Vein of Madness, a theatrical adaptation of Alessio Arena's acclaimed 2020 book, "La vena verde". Similarly engaging with Pirandello's legacy, Pierlorenzo Randazzo's "The Six Characters of Giuseppe Fava's Delirio (1980)" offers a detailed comparative analysis of Fava's play "Delirio" and Luigi Pirandello's "Six Characters in Search of an Author" (1921). Randazzo explores how Fava reimagines Pirandello's work in a farcical light, employing this reinterpretation to highlight Pirandello's metatheatrical techniques, which serve as a metaphor for the crisis of human identity. While both plays address themes of lost identity, Delirio sets itself apart by depicting its characters as concrete, earthly beings, as opposed to the more abstract and conceptual characters found in Pirandello's original work

Abstract: The optimization of difference patterns of monopulse antennas is considered. The synthesis problem is recast as an optimization problem by defining a suitable cost function. In particular, in this paper, the cost function is based on constraints on the side-lobe levels. A subarray configuration is adopted and the excitations of the difference pattern are approximately determined. The optimization problem isefficiently solved by a differential evolution algorithm, which is able to contemporarily handle real and integer unknowns. Numerical results are reported concerning classical array configurations previously considered in the literature.

Comparison of Genetic and Reinforcement Learning Algorithms for Energy Cogeneration Optimization
No full textLarge process plants generally require energy in different forms: mechanical, electrical, or thermal (in the form of steam or hot water). A commonly used source of energy is cogeneration, also defined as Combined Heat and Power (CHP). Cogeneration can offer substantial economic as well as energy savings; however, its real-time operation scheduling is still a challenge today. Multiple algorithms have been proposed for the CHP control problem in the literature, such as genetic algorithms (GAs), particle swarm optimization algorithms, artificial neural networks, fuzzy decision making systems and, most recently, reinforcement learning (RL) algorithms.This paper presents the comparison of a RL approach and a GA for the control of a cogenerator, using as a case study a thermal power plant serving a factory during the year 2021. The two methods were compared based on an earnings before interest, taxes, depreciation, and amortization (EBITDA) metric. The EBITDA that could be obtained using the RL algorithm, exceeds both the EBITDA that could be generated using a per-week genetic algorithm and the one from the manual scheduling of the CHP. Thus, the RL algorithm proves to be the most cost-effective strategy for the control of a CHP
Different mycorrhizal symbionts affect phenolics content and antioxidant activity in diverse artichoke and tomato plant cultivars
No full textIntroduction
Globe artichoke and tomato are considered “functional foods”, showing high levels of secondary metabolites with health-promoting activities. The content and composition of such bioactive molecules may be greatly affected by plant genotype and by the association with beneficial symbionts, such as arbuscular mycorrhizal fungi (AMF), a key group of soil microorganisms considered natural biofertilizers and bioenhancers. However, while plants have been widely investigated for bioactive molecules production, only few AMF were studied, thus limiting the full exploitation of their physiological and genetic diversity.
Material and methods
In this work the antioxidant activity and total phenolics of artichoke leaves and flower heads and of tomato fruits were assessed in different plant cultivars (two in artichoke and four in tomato) inoculated with AMF isolates belonging to diverse genera and species (Funneliformis mosseae, Funneliformis coronatus, Funneliformis caledonius, Rhizoglomus irregulare, Claroideoglomus claroideum, Glomus sp.).
Results
The different AMF isolates showed a variable rate of mycorrhizal colonization, depending on plant cultivar both in artichoke and in tomato. Differences in bioactive molecules were also observed among plant cultivars and symbionts. For example, significant increases of total phenolics and antioxidant activity, compared with controls, were observed in relation to the diverse AMF species used, with C. claroideum 22W3 as the best performing isolate. Moreover, in artichoke the levels of total phenols, chlorogenic acid and antioxidant activity increased in one cultivar, compared with the other.
Conclusions
The present study, comparing a high number of diverse AMF in relation to the production of health-promoting secondary metabolites, is important to enhance our knowledge on the functional diversity of this key group of soil beneficial microbes and to detect the best performing ones to be used for obtaining high quality food, which is an important societal issue strongly demanded by both consumers and producers

No full textOccurrence, diversity, and persistence of antibiotic resistant enterococci in full-scale constructed wetlands treating urban wastewater in Sicily
No full textEnterococci isolated from different sites of an urban wastewater treatment plant (consisting of three horizontal subsurface flow constructed wetlands) were investigated. One-hundred-thirty isolates were identified at species level and tested for resistance to eleven antibiotics, by microdilution method, and their clonal relatedness was established by SmaI-PFGE analysis. Results highlighted the persistence of enterococcal population in all effluents and the dominance of E. faecium species. A high incidence of antibiotic resistance against erythromycin, chloramphenicol, rifampicin and ampicillin was observed, with 120 strains (93%) showing a multi-drug-resistance. Numerous pulso-types with a unique pattern were detected indicating a high diversity within enterococcal population. The recurrence of some pulso-types in different effluents was disclosed and, within the same pulso-types, different resistance patterns were observed. Comparing the MIC values of strains from inlet and outlet, different trends were observed, highlighting a certain variability among constructed wetlands in affecting the antibiotic resistance among enterococcal population
