Full text linkThe pet food industry generates significant waste, including expired products that are often discarded, contributing to environmental concerns. This study explores the potential of using expired canned cat food as a rearing substrate for Black Soldier Fly Larvae (BSFL, Hermetia illucens), evaluating its impact on larval growth and nutrient composition. Three expired canned cat foods (beef, chicken and salmon-based) were tested against a commercial broiler diet as a control (CTRL). Results indicate that BSFL successfully developed on all tested substrates, with the salmon-based diet (SD) yielding the highest growth rate (0.010 g/day, p < 0.01) and nutrient assimilation, similar to the control group. The beef-based diet (BD) resulted in lower lipid accumulation (16.98% DM, p < 0.05), while all substrates influenced the larvae’s protein (ranging from 43.12% to 45.64% DM) and fatty acid profiles. Notably, lauric acid, a key antimicrobial and metabolic compound, remained predominant in all larvae, with values ranging from 42.18% (BD) to 60.34% (CTRL) of total fatty acids (p < 0.01). These findings highlight the feasibility of expired pet food as a valuable resource for insect farming, promoting circular economic principles. However, regulatory constraints currently limit their use in feed applications. Future research should address legal considerations and optimise substrate formulations to enhance larval performance and industrial applications
Enzymatic Hydrolysis of Hemp Seed Cake Flour: Impact on Technological Properties
No full textThis study explored improving the technological properties of hemp seed cake flour through enzymatic hydrolysis. Before hydrolysis, the biomass underwent a delignification pre-treatment using a deep eutectic solvent made of glycerol and choline chloride to remove lignin and enhance treatment yield. Hydrolysis significantly increased the polyphenol content from 1821 mgGAE/kgdw for untreated flour up to 4387 mgGAE/kgdw due to enzymatic action and lignin removal, which made phenolic compounds more accessible within the matrix. The hydrolyzed flour exhibited higher oil adsorption and water-holding capacities, attributed to the increased availability of hydrophobic and polar ionizable groups. Moreover, the process transformed insoluble fibers into a more amorphous form, enhancing water interaction and improving the swelling and water adsorption indices. Regarding foaming properties, enzymatic treatment increased foam capacity up to 8.1 v/v but reduced its stability, leading to its complete disappearance within 45 minutes. Finally, the hydrolyzed flour demonstrated reduced emulsifying capacity but improved emulsion stability
La Relazione Gaudioso sulla Basilicata per Carlo di Borbone, edizione critica, con trascrizione integrale del ms XIV.D.39 della Biblioteca Nazionale di Napoli a cura di Italia Manolio, Nunzia Nicoletti e Maria Emilia Serafino
No full textSi tratta della relazione che venne compilata nel 1736 dal marchese di Camporeale Rodrigo Maria Gaudioso, Avvocato Fiscale della Regia Udienza della Provincia di Basilicata, per ordine di Carlo di Borbone, re delle Due Sicilie dal 1735 al 1759, e per il tramite del primo ministro, il toscano Bernardo Tanucci. Di questa relazione – una vera e propria inchiesta sulla situazione civile, amministrativa ed economica in cui versava allora la provincia – si offre finalmente l’edizione dell’intero codice napoletano, che costa in totale di 433 carte, e che si apre (alle cc. 6r-44r, ovvero cc. 1-38 nella numerazione antica) con la Relazione del Gaudioso, mentre contiene ai fogli seguenti le relazioni più ampie e dettagliate che tutte le locali comunità urbane (Università) furono chiamate a redigere, per mano dei loro Cancellieri, su richiesta dello stesso Rodrigo Maria Gaudioso
Dissecting lentil crop growth in contrasting environments using digital imaging and genome‐wide association studies
Full text linkThe development of high-throughput phenotyping platforms to capture time-series data on large, diverse populations holds promise for crop researchers and breeders investigating growth-related traits. We used imagery from unoccupied aerial vehicles (UAVs) with red/green/blue (RGB) and multispectral cameras flown over multiple site-years in Saskatchewan, Canada, and Metaponto, Italy, to gather data for crop height, area, and volume in a lentil diversity panel (324 genotypes). The temporal nature of the UAV image-derived data enabled the modeling of growth curves for volume, height, and area, something that would be impractical under traditional phenotyping procedures in such a large population grown in multiple environments. A principal component analysis and hierarchical clustering revealed differential growth patterns across contrasting environments, with large variations in temperature and photoperiod, within our lentil diversity panel. Combining this analysis with genome-wide genotyping data, we identified markers, from an exome capture array (267,845 single nucleotide polymorphisms), associated with crop growth that could be used for marker-assisted selection. Our study demonstrates the potential for UAV-based imaging to obtain large-scale time-series data across multiple environments to model growth curves and investigate genotype-by-environment interactions. In addition, we can now use phenotypic traits that were once impractical to collect and derive novel phenotypes to improve our understanding of crop growth and the genetics underlying adaptation in lentil, approaches that will be useful for both researchers and breeders
Alternative source of chitosan for the direct laser synthesis of Ag@chitosan composites with antibacterial and photocatalytic properties
Full text linkIn this study, we used chitosan obtained from the pupal exuviae of the insect Hermetia illucens to produced silver nanoparticles (Ag@CSE) by nanosecond laser ablation in liquid technique. The physic-chemical and functional properties of the obtained nanocomposite were compared to Ag@CS prepared by using a solution of chitosan from crustaceans as liquid, in the same experimental conditions. The composites were studied by transmission electron microscopy (TEM), Uv-vis and FTIR and X-ray photoelectron spectroscopy (XPS) and X-ray diffractometry (XRD). The composites exhibit optical absorption at around 400 nm due to the presence of silver nanoparticles with a diameter of 11 and 14 nm for Ag@CS and Ag@CSE, respectively. We evaluated the antimicrobial capacity of these nanocomposites against two bacterial strains, Escherichia coli and Micrococcus flavus, by agar diffusion test and microdilution assay. Both composites showed a zone of inhibition of approximately 9 mm against both bacterial strains. Ag@CSE showed marked antimicrobial activity against E. coli up to 0.006 g/L, at which value Ag NPs alone lost their activity. The ability to photocatalyse the methylene blue degradation reaction of Ag@CS and Ag@CSE was tested under simulated solar irradiation conditions. The obtained results suggest that chitosan from HE is a valuable alternative source to chitosan from crustaceans and that the obtained composites can be considered for biomedical and photodegradation applications

No full textImprese e Politica di Coesione in Italia: Analisi e Prospettive dai Dati Integrati
No full textLe imprese svolgono un ruolo chiave nei processi di crescita e convergenza economica, grazie alla loro capacità di generare valore aggiunto e creare opportunità economiche e occupazionali. Sono dunque unità di analisi cruciali per valutare l'efficacia delle politiche di coesione e individuare possibili aree di miglioramento nelle misure attuate. Questo studio utilizza un archivio arricchito che collega i microdati sulle principali caratteristiche anagrafiche, economiche, strutturali e di performance delle imprese italiane (dagli archivi dell’ISTAT ASIA e Frame-SBS) con le informazioni relative ai progetti finanziati dalla coesione a livello settoriale e territoriale (Open-Coesione). Sulla base di questo sviluppo statistico, il nostro lavoro fornisce una panoramica delle imprese che hanno avuto accesso ai finanziamenti delle politiche di coesione, arricchendo la dimensione territoriale con una caratterizzazione delle imprese beneficiarie in termini di valore aggiunto, capacità occupazionale, produttività e intensità tecnologica e/o di conoscenza. L’analisi descrittiva fornita evidenzia che, sebbene le imprese beneficiarie siano numericamente limitate, esse rivestono un peso rilevante in termini di addetti e valore aggiunto. Tuttavia, la distribuzione settoriale e territoriale del sostegno solleva interrogativi sulla sua efficacia nel massimizzare la crescita locale. I finanziamenti tendono infatti a rafforzare le specializzazioni produttive esistenti: nel Mezzogiorno prevalgono le imprese dei servizi a bassa intensità di conoscenza, mentre nel Nord Italia i fondi sono principalmente destinati ai settori manifatturieri, soprattutto high-tech. Questa allocazione potrebbe limitare l’impatto della coesione nel ridurre le disparità territoriali, suggerendo la necessità di una strategia più selettiva, orientata a settori e imprese con un maggiore potenziale di crescita e innovazione
Dal familismo alle reti di relazione Rapporti sociali e pratiche patrimoniali in tre Comuni dell’area interna “Mercure - Alto Sinni - Val Sarmento”
No full textThe thesis presents the results of the ethno-anthropological study carried out as part of the 'municipal' PhD project, which was established through agreements between the University of Basilicata and three municipalities in Lucania recognised by the Strategia Nazionale per le Aree Interne (SNAI): Francavilla in Sinni, Chiaromonte and Terranova di Pollino. These municipalities are part of the Mercure - Alto Sinni - Valsarmento area.
The collaboration with the Osservatorio scientifico regionale per la salvaguardia del patrimonio etno-antropologico della Basilicata, named after the American sociologist and political scientist Edward C. Banfield (who conducted research in Chiaromonte in the 1950s and developed the concept of 'amoral familism' in “The Moral Basis of a Backward Society” [1976]) was motivated by the desire to review and update the scope of social change processes and public action mechanisms in the area. The research focuses on the community relationships within the area, which were explored through collaboration with local institutions and associative networks of various kinds. The aim is to gain in-depth understanding of the forms of civic participation and social inclusion. The understanding of the transformations that have taken place in the inland areas studied by Banfield is key to identifying traces of permanence and signs of break with respect to his work and the memory of his presence, evaluating the factors that influence social relations and levels of political action today.
The research has therefore been refocused on local society, which is involved in new agencies and multi-level intervention strategies. This is achieved through case studies dedicated to specific communities, following the intertwining of family, associations and informal networks, as well as the role of pivotal institutional and non-institutional figures. The results of the fieldwork contribute to a complex view of the interaction between institutional spheres and bottom-up practices. Similarly, research experiences in other areas of inland Lucania can be considered, such as the interdisciplinary research project “RI.P.R.O.VA.RE. - RIabitare i Paesi. Strategie Operative per la Valorizzazione e la Resilienza delle aree interne” which involved six villages in the Agri Valley.
In the "lands of the bone", global cultural processes are often grafted onto local dynamics, and relations are stratified across generations and places, thinning the boundary between individuals, groups (formal and informal) and institutional bodies.
By reconstructing the study from a multi-sited perspective and emphasizing the various roles of the researcher in the field, we can highlight the frictions and convergences between institutional and project orientations of the actors and activists engaged in the territories. These dynamics show the multiple nuances of relationships in fragile areas recognized as marginal due to the extreme lack of material and immaterial infrastructures, while participant immersion provides access to intimate spaces of community life and close points of view. The need to apply diversified approaches of investigation and interaction with institutions and people is revealed, not only to respond to different needs, times, and modes of research, but also due to the essential interest in the specificity of countries, which are unique and cannot be categorized in technical definitions. At the same time, the delicate permeability of closely defined fields of study that are remote and sheltered from massive "external" gazes explains the potential of working together with inhabitants, organizations, and institutions, and emphasizes ability to mediate and the facilitating function of ethnographic activity.
The intention to understand the difficulties and possible horizons, bringing local experiences into dialogue with each other and opening up comparisons with other regional and national contexts, corresponds to the proposal to develop the Osservatorio's presence and to relaunch the value of the anthropological perspective, as a connection between social institutions, scientific interests, and personal initiatives in the area
