Quattro commedie per le giovinette d'Italia
No full textIl volume racchiude la pubblicazione di quattro commedie scritte da Grazia Pierantoni Mancini. Grazia Pierantoni Mancini nacque a Napoli, figlia di Laura Beatrice Oliva, poetessa e “musa del Risorgimento”, e da Pasquale Stanislao Mancini, insigne avvocato. La famiglia dovette vivere in esilio a Torino dove il padre partecipò attivamente agli incontri in preparazione dell’Unità d’Italia. Scrittrice precoce e prolifica, Grazia si dedicò alla narrativa (romanzi e novelle), al giornalismo collaborando a «La Nuova Antologia», alla rivista «La Donna», a «Vita italiana», alle traduzioni di opere straniere, e alla scrittura per il teatro. Sposò Augusto Pierantoni nel 1868. Morì a Roma nel 1915.

Microextraction techniques: a critical review
No full textThe quality of the sample preparation procedure will determine the quality of the data produced and, consequently, the ability to obtain reliable and affordable data. In this context, microextraction techniques (METs) represent a quite recent innovation in the field of extraction techniques making use of low sample volumes and giving purification levels necessary for the characterization of the target analytes. Solid phase microextraction (SPME)1 and, more recently, microextraction by packed sorbent (MEPS)2, are powerful sample preparation techniques, characterized by their reduced time of analysis, low solvent consumption, and broad application. Moreover, as miniaturized techniques, they can be easily automatized to have a high-throughput performance in the clinical environment. These techniques are possibly the most suitable to process samples in agricultural, environmental and clinical fields, given the complexity of the matrix, containing many inherent interferents, and the need to minimize cost through automation and high throughput solutions3. Simultaneously, they are fast, simple, sustainable, and user-friendly systems that can be easily automated4. SPME and different configurations of MEPS allow the integration of several procedures (sample extraction, concentration, and loading) in a single step, thus limiting the existence of experimental errors. Microextraction techniques have several sorbent materials commercially available that can be packed in permanently used syringes of modern high-end autosampler devices4; new and promising materials are continuously being characterized5. These techniques present a high throughput potential able to correspond to the demands of agricultural, environmental, medical and clinical analysis. In this talk, a review of microextraction techniques and the last innovations in the field will be presented.

Cooperation against invasions: multi-agent control of alien species in connected landscapes
No full textInvasive alien species (IAS) increasingly threaten biodiversity, ecosystem services, and economic sustainability, particularly in fragmented landscapes where management responsibilities are decentralized. The spread of IAS is not confined within administrative borders: it follows ecological connectivity, making isolated local interventions often ineffective. This work presents a dynamic game-theoretic framework for modeling the strategic management of IAS across a network of heterogeneous areas linked by spatial diffusion. Each agent, responsible for local control of the invasion, faces a trade-off between reducing ecological damages and sustaining the economic costs of intervention. The analysis explores how the interaction between spatial structure, ecological features, and decentralized decision-making shapes outcomes under non-cooperative, coalition-based, and fully cooperative strategies. To support the cooperative behavior, fair cost-allocation mechanisms are proposed based on Nash bargaining and the Myerson value, explicitly accounting for spatial externalities. Numerical experiments on a synthetic three-node network illustrate how cooperation can substantially reduce invasion spread and management costs, while strategic defection may exacerbate both ecological and economic losses. The main findings of the analysis underline the vulnerabilities of fragmented management and the need for institutional arrangements to promote adaptive, equitable, and spatially informed strategies for IAS control
Simultaneous determination of (lipo)phenolic compounds in olive oil by-products by dual-injection single-run LC-MSMS analysis
No full textThe olive oil sector is experiencing significant growth, driven by the global appreciation of olive oil as a high-nutritional food. However, its industrial production generates large amounts of by-products, including olive pomace (OP)—mainly water, pulp, and seeds—and olive oil mill wastewater (OOMW), a dark liquid rich in organic carbon, especially phenolic and polyphenolic compounds. These residues, if not properly treated, may pose environmental hazards due to their phytotoxic and antimicrobial properties. On the other hand, they are rich in bioactive compounds with antioxidant potential, making them valuable for creating eco-sustainable and economically beneficial co-products.
Established chromatographic methods are typically optimized for either polyphenolic or lipophenolic compounds, reflecting their distinct solubility properties and chemical structures [1,2]. Indeed, their simultaneous determination is analytically demanding, especially when selecting solvents compatible with both solubilization processes and chromatographic eluents.
In this study, a comprehensive determination of (lipo)phenolic compounds in olive oil by-products was conducted using a UHPLC-LTQ Orbitrap XL HRMS system with a heated electrospray ionization (HESI) source. A dual-injection single-run approach was applied, integrating an on-line focusing step for trapping lipophenols, followed by injection of polyphenols. Then, the method involves two consecutive injections combined into a single run using a binary gradient program, enabling efficient separation of phenolic and (lipo)phenolic compounds with high-throughput workflows. A baseline separation of the target analytes was obtained in less than 25 min. Overall, the analysis requires a total time of 34 min, including the step of column conditioning for the next run. Finally, the method was applied for both targeted and untargeted profiling of OP, OOMW, and leaves from three Olea europaea cultivars.
