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.

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
Prefazione
No full textIl contributo introduce il volume collettaneo (co-edito dagli autori della Prefazione, assieme a Stefaan Voet) su “L’azione di classe italiana nel quadro europeo profili sostanziali e processuali”, edito da Giappichelli e pubblicato a Torino nel 2025. La prefazione illustra sinteticamente il contenuto del volume (che indaga alcune delle molteplici problematiche teoriche e pratico-applicative poste dall’istituto processuale della “class action” come declinato dal legislatore italiano, attraverso saggi di taglio multidisciplinare e comparato dedicati
alle azioni “generali”, alle azioni “speciali”, ai profili di case management). La prefazione ricorda come il volume approfondisca le tematiche discusse nell’ambito di un seminario di studi interdisciplinare organizzato presso l’Università degli Studi di Milano nel febbraio 2023 – in attesa dell’entrata in vigore del d.lgs. n. 28 del 2023 – dal Centre of Research on Domestic European and Transnational Dispute Settlement, in collaborazione con il Modulo Jean Monnet Access to Justice in a Multilevel European Constitutional System e come intenda ulteriormente contribuire al confronto tra accademia, mondo giudiziario e delle professioni legali, associazioni dei consumatori e funders su un istituto processuale che, nonostante le innumerevoli criticità, promette di svolgere nei prossimi anni un ruolo sempre più incisivo nella tutela dei diritti fondamentali.

Il volume approfondisce le tematiche discusse nell’ambito di un seminario di

febbraio 2023 – in attesa dell’entrata in vigore del d.lgs. n. 28 del 2023 – dal
Centre of Research on Domestic European and Transnational Dispute Settlement
in collaborazione con il Modulo Jean Monnet Access to Justice in a Multilevel
European Constitutional System. Già in quell’occasione il confronto tra
esperti di diverse professioni e discipline giuridiche apparve particolarmente fecondo;
il presente lavoro intende pertanto ulteriormente contribuire al confronto
tra accademia, mondo giudiziario e delle professioni legali, associazioni dei consumatori
e funders su un istituto processuale che, nonostante le innumerevoli criticità,

A Study of the Standard Potential of the Mercuric-Mercurous Ions in the Presence of Chloride Ions
No full textIn the field of electrochemistry there has been a vast amount of work done in determining the standard potentials of various systems. The importance of calculating these standard potentials can clearly be seen since they are of use in obtaining equilibrium constants and activity coefficients of solutes. The standard potential may be defined as the emf of an electrode or cell when all ions of the system are at unit activity. |Although standard potentials have been calculated for many mercury systems, data concerning the standard potential for the mercuric-mercurous system in the . presence of chloride ion could not be obtained from available literature. The object of this study then is to determine this standard potential. This is attempted by determining the electrode potentials of mercuric chloride and potassium chloride solutions of varying concentrations measured against the saturated calomel electrode. In accordance with universal usage this standard potential is determined in terms of the molality scale has the distinct advantage of being independent of temperatureProQuest Traditional Publishing Optio

Loading carbonaceous materials with silver for the treatment of chloro-organic compounds in aqueous phase
No full textMany electrochemical technologies, either based on novel concepts (such as microbial fuel cells), experimental setups (such as photoelectrochemical or solar photoelectro-Fenton reactors) or materials (mainly focused on the use of large O2-overpotential anodes like BDD) have been devised in recent years for water remediation. Special attention has been paid to highly toxic, biorefractory organic pollutants such as the chlorinated hydrocarbons, which conjugate toxicity with chemical stability, bioaccumulation and long-range diffusivity [1].
Electroreduction at silver cathodes becomes an interesting alternative to degrade chloro-organic compounds, but it may lead to the accumulation of reaction by-products, even upon coupling with electro-oxidation at BDD [2]. On the other hand, some Fenton-based processes have proven very effective for the destruction of organic matter due to the action of •OH formed when cathodically electrogenerated H2O2 reacts with added Fe2+ [3]. Based on this, we have envisaged a potential strategy for the enhanced removal of chloro-organic pollutants and their by-products: electro-Fenton process in the bulk upon H2O2 electrogeneration at a carbonaceous cathode, which can simultaneously act as the substrate for electroreduction at loaded Ag nanoparticles. To achieve this goal, a highly efficient material for H2O2 production, i.e., a gas diffusion electrode (GDE), has been chosen for Ag-loading experiments. Several authors have reported the preparation of Ag-loaded carbonaceous materials based on a simple electroless deposition (ELD) process from Ag+ solutions. Some of them have addressed the full preparation of GDEs with Ag catalysts [4,5].
Here, we report the use of a commercial GDE as a suitable substrate to obtain conveniently dispersed Ag nanoparticles. The effect of several ELD parameters (e.g., nature of reductant, mode of application and deposition time) on the surface morphology has been mainly studied by SEM-EDX. Bulk electrolyses in 50 mM Na2SO4 at various pH were subsequently performed with the best materials to assess their ability to electrogenerate H2O2. For comparison, carbon paper was used as an alternative substrate. An important objective of the research was to find the optimum conditions to load the substrate so as to keep the balance between covered and uncovered area, in order to favor both H2O2 production and pollutant electroreduction. The performances of these electrodes for the electrogeneration of H2O2 and the abatement of chloro-organic pollutants is currently being investigated.
