Variation in meat quality characteristics between Landrace and Sicilian pigs
2019
This study compared the meat quality of Sicilian and Landrace pigs breeds and supported these results with biochemical and histological measurements on the samples collected from the m. Longissimus Dorsi, at the level of the 8th thoracic vertebra, before electrical stimulation. Twenty clinically healthy swine, 10 male (5 for each pig breed) and 10 female (5 for each pig breed), were slaughtered at 1 year of age at a body mass of 135±10 kg and 150±10 respectively for Sicilian and Landrace pigs. Particularly on the muscle considered the morphometric characteristics of FG (fast glycolytic), FOG (fast oxidative glycolytic) and SO (slow oxidative) fibre types and their percentage were determined…
Role of the support and pseudo-liquid phase in the Phosphotungstic Heteropolyacid (photo)catalytic activity
2016
Catalytic and photocatalytic tests for propene hydration to 2-propanol were successfully carried out by using binary materials obtained by supporting a Keggin or Wells-Dawson heteropolyacids via impregnation method to commercial SiO2 or TiO2. (Photo)catalytic hydration was studied in gas-solid regime by using a continuous (photo)reactor working at atmospheric pressure and 80 °C. The alcohol was the main product. The acidity of the cluster accounts for the catalytic role, whereas both the acidity of the cluster and the oxidant ability were responsible for the increase of the reaction rate of the photo-assisted catalytic reaction. Moreover, the presence of a photoactive semiconductor support …

IAEA Contribution to Nanosized Targeted Radiopharmaceuticals for Drug Delivery.
2022
The rapidly growing interest in the application of nanoscience in the future design of radiopharmaceuticals and the development of nanosized radiopharmaceuticals in the late 2000′s, resulted in the creation of a Coordinated Research Project (CRP) by the International Atomic Energy Agency (IAEA) in 2014. This CRP entitled ‘Nanosized delivery systems for radiopharmaceuticals’ involved a team of expert scientist from various member states. This team of scientists worked on a number of cutting-edge areas of nanoscience with a focus on developing well-defined, highly effective and site-specific delivery systems of radiopharmaceuticals. Specifically, focus areas of various teams of scientists com…
Realtà aumentata: nuovi scenari di apprendimento?
2020
Scopo del presente contributo è esplorare le implicazioni per l’apprendimento che hanno luogo alle frontiere della realtà in cui il virtuale e il reale si integrano per creare nuovi scenari di apprendimento. Sono dapprima illustrate le caratteristiche della Realtà Aumentata per poi approfondire le teorie dell’apprendimento e le pratiche didattiche che consentono di integrarle efficacemente in ambito scolastico ed accademico. Ci si sofferma, infine, su alcune peculiarità utili ai fini didattici per poi esaminare alcune criticità e questioni ancora aperte.
Recupero di un'area dismessa a Siracusa
2010
The article describes the proposed redevelopment of a derelict industrial zone in Siracusa, through interventions on ten buildings destined to become tourist and hotel accommodation. The types of installation, materials and buildings techniques to be employed will render the proposed salvage operation sustainable, along with innovative technology and bio-architecture, the use of renewable energy source, all in accordance with the principle of energy-saving.
Developing Tele-Operated Laboratories for Manufacturing Engineering Education
2010
The aim of the PeTEX-project is to establish an e-Learning platform for the development, implementation, and delivery of educational training programs in the field of manufacturing engineering. The PeTEX team designs both: a technical platform for eLearning based on “Moodle” including distributed tele-operated experimentation facilities, and didactic and socio-technical requirements for a successful online learning community. User interfaces are deployed for remote access to instruments, data analysis and multiplexed data access via network protocols. Hence, the platform provides complex tools in order to perform various activities to support the educational process, from telemetric experim…
Accessibilità e fruibilità dei centri storici: un’opportunità per il Restauro
2020
L’eguaglianza di tutti, nel rispetto delle diversità, è un diritto costituzionale e contempla anche il diritto di tutti alla trasmissione di quei valori dell’architettura storica, riconosciuti e tutelati dal restauro. Valori che sono patrimonio collettivo, da conservare, trasmettere e fruire sia per le generazioni future che per quelle attuali. È difficile, quindi, pensare ad “una legge, o ad una teoria che voglia tutelare il monumento e non le persone, ad una cultura che prescinda dall’uso nel senso più ampio del termine”. Difatti, a distanza di trent’anni dall’emanazione in Italia della legge 41 del 1986, per l’introduzione dei Piani di Eliminazione delle Barriere Architettoniche (PEBA) e…
Sustainable Recycling of Insoluble Rust Waste for the Synthesis of Iron-Containing Perovskite-Type Catalysts
2019
Insoluble rust waste from the scraping of rusted iron-containing materials represents a cheap, eco-friendly, and available source of iron. LaFeO3 perovskite-type powders were successfully prepared by solution combustion synthesis using rust waste from an electricity transmission tower manufacturer. Solution combustion synthesis enabled introduction of this insoluble iron precursor directly into the final product, bypassing complex extraction procedures. Catalytic activity in the propylene oxidation of the waste-derived LaFeO3 with stoichiometric Fe/La ratio was almost identical to the commercial iron nitrate-derived LaFeO3 , thus demonstrating the viability of this recycling solution. The a…
