Realizacja Konwencji UNESCO z 2003 roku w Polsce z perspektywy folklorysty

2018

The author continues her research on folklore and folklorism in the contemporary culture in the framework of the discussion held currently in Poland on the intangible cultural heritage and all the actions aiming at its protection and preservation. She starts from 2003 UNESCO Convention which coins the new term of intangible cultural heritage to replace the terms folklore and folklorism, commonly used in informal and scientific discourse. The new term covers also material culture. The author has already referred to the complex set of phenomena that accompany the change in terminology, pointing e.g. at the growing discrepancy between the academic theory and the cultural policy of the state.

Application of bacteriocins in vegetable food biopreservation.

2007

Bacteriocins are generally recognized as "natural" compounds able to influence the safety and quality of foods. In the past years, a lot of works have been aimed to the detection, purification and characterisation of bacteriocins, as well as to their use in food preservation strategies. A list of review articles dealing with the application of bacteriocins to the protection of foods of animal origin is also available in literature, but it lacks for a summary on the utilization of bacteriocins in vegetable foods. These biopreservatives can be used in a number of ways in food systems and this paper mainly focuses on the state-of-the-art application of bacteriocins from lactic acid bacteria (L…

Effect on Orange Juice of Batch Pasteurization in an Improved Pilot-Scale Microwave Oven

2010

The effects on orange juice batch pasteurization in an improved pilot-scale microwave (MW) oven was evaluated by monitoring pectin methyl-esterase (PME) activity, color, carotenoid compounds and vitamin C content. Trials were performed on stirred orange juice heated at different temperatures (60, 70, 75, and 85 degrees C) during batch process. MW pilot plant allowed real-time temperature control of samples using proportional integrative derivative (PID) techniques based on the infrared thermography temperature read-out. The inactivation of heat sensitive fraction of PME, that verifies orange juice pasteurization, showed a z-value of 22.1 degrees C. Carotenoid content, responsible for sensor…

Interface and aroma barrier properties of iota-carrageenan emulsion–based films used for encapsulation of active food compounds

2009

Abstract Food quality preservation requires that the initial properties of the food products be maintained by protecting them from the environment and by limiting the gain or loss of external matter. Barrier edible films can preserve food quality by controlling moisture transfer, oxygen uptake or the loss of volatile aroma compounds. Edible films made of iota-carrageenans display interesting advantages: good mechanical properties, stabilization of emulsions and reduction in oxygen transfer. Moreover, lipid globules incorporated as emulsion-based films can be the carriers for the encapsulation of active volatile molecules such as flavor compounds. Such films also enhance the barrier properti…

Towards resilient cities: Advancements allowed by a multi-criteria optimization tool to face the new challenges of European Union’s climate and energ…

2019

Abstract The United Nations as well as the European Union are strongly committed in promoting a transition towards more sustainable and resilient cities. Indeed, they are increasingly affected by different types of threats, among which the natural ones such as earthquakes, fires, and floods (shocks) and climate variability (stresses). Cities are quite often unable to cope with the adverse effects of such natural hazards. This circumstance leads to the need of introducing resilience-related criteria (besides commonly used sustainability indicators) in decision-making processes. This paper investigates at which extent the inclusion of such new indicators, within multi-criteria assessment tool…

Recovery and refurbishment of the buildings of the former Gulì textile factory in Palermo

2019

The industrial activity of Palermo, despite having lived a rather short prosperous period, has left traces that are well recognizable and identifiable with architectural artefacts of considerable importance for design quality and size. The Gulì factory, designed by the architect Pietro Scibilia, a pupil of Ernesto Basile, is a piece of history incorporated into the urban fabric. In fact, the designer is a key player in the quality of the Palermo building production of the last century and the Gulì factory is an interesting complex both from the architectural point of view and its urban location, very close to the historical center and significant cultural interest poles. The architectural s…

Recovery and refurbishment of the buildings of the former Gulì textile factory in Palermo

2019

L’industria palermitana, pur avendo vissuto un periodo fiorente piuttosto breve, ha lasciato tracce ben riconoscibili e identificabili con manufatti architettonici di grande importanza per qualità di progetto e dimensioni. La fabbrica Gulì è molto interessante sia dal punto di vista architettonico sia per la sua localizzazione urbanistica molto prossima al centro storico e a poli di rilevante interesse culturale. L’impianto architettonico, abbandonato e privato della sua funzione originaria, mantiene una forte memoria storica e collettiva e possiede interessanti potenzialità non solo per la sua configurazione volumetrica ma soprattutto per i caratteri tipologici che la connotano. Lo studio …

New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: is there more than one species?

2021

The Triassic basal sauropodomorph Plateosaurus trossingensis is well-known from mass accumulations at the German localities of Trossingen and Halberstadt and the Swiss locality of Frick, and is significant especially regarding its ta-phonomy and proposed developmental plasticity. These implications, however, rely on the assumption that this material derives from a single species, which has been questioned. Here we describe new skull material from Frick including eight complete and six partial skulls, more than doubling the number of known skulls of P. trossingensis. This exceptional sample size allows for gaining a deeper understanding of variability that may occur in a single species. The …

Ionic Liquid Gels: Tunable and Multifaceted Materials

Materials based on ionic liquids retain properties of solvent components, like low vapor pressure, high thermal stability and structure tunability. The latter allows changing properties of materials by making small variations in the cation or anion structure, opening the way to a plethora of different applications. In this context, ionic liquid gels can represent a challenge especially if they are obtained from gelation of ionic liquid binary mixtures or of organic salts in ionic liquids. In the framework of our interest in studying ionic liquids properties and applications, in the last few years, we have addressed our attention to the obtainment of ionic liquid gels.1 We have deeply invest…

Tre Sicilie: nascita, distruzione e ri-ciclo dei paesaggi siciliani

2015

L’evoluzione delle politiche sul paesaggio in Sicilia vive una sorta di tripartizione sia storica che geografica: paesaggi tutelati e iper-protetti, paesaggi in trasformazione e paesaggi in recupero si susseguono evolutivamente nella storia dell’Isola, ma si giustappongono anche fisicamente nella contemporaneità. Questa realtà è oggetto di questo contributo che indaga evoluzione ed esiti di creazione, trasformazione e riciclo di paesaggi in alcuni territori esemplari della Sicilia, con l’obiettivo di analizzare, selezionare e proporre buone (o cattive) pratiche nell’ambito della ri-generazione dei paesaggi. Il contributo in forma di cronistoria fortemente selettiva di alcuni fenomeni che ha…
