PROTEGGERE E VALORIZZARE: RIFLESSIONI PER UNA BUONA PRATICA SUI SITI ARCHEOLOGICI
2014
Tra i beni culturali quelli archeologici hanno più animato il dibattito culturale sul rapporto fra conservazione e valorizzazione. La fragilità con cui la materia ci viene consegnata dalla storia, la frammentarietà del reperto, la scarsa disponibilità di risorse finanziarie, in relazione anche alla vastità del patrimonio a noi pervenuto, impongono interventi mirati e talvolta urgenti per la salvaguardia e la conservazione di tali beni. Ma la sola conservazione non può costituire l’obiettivo ultimo dell’intervento: essa deve interessare anche azioni di messa in valore, di fruizione e di comunicazione, necessarie per favorire un nuovo ruolo a queste realtà private dell’originaria identità. Qu…
Selection of novel geopolymeric mortars for sustainable construction applications using fuzzy topsis approach
2020
Construction is recognized as one of the most polluting and energy consuming industries worldwide, especially in developing countries. Therefore, Research and Development (R&
Obowiązkowa część systemu emerytalnego - jaka będzie wysokość emerytury przeciętnego Polaka?
2018
Oczekiwaniem każdego człowieka jest uzyskanie po okresie aktywności zawodowej odpowiednio wysokiej emerytury. Takiej, która zapewni mu niezależność finansową w okresie starości. Czy będąc członkiem społeczeństwa podlegamy pewnym ograniczeniom, czy rzeczywistość gospodarcza kreuje w nas pewne zachowania? Odpowiedź jest jak najbardziej twierdząca. Uczestnictwo w życiu społeczno-gospodarczym wymusza na jednostce przystąpienie do systemu emerytalnego i tym samym powoduje konieczność stosowania się do reguł w tym systemie obowiązujących. Celem publikacji jest przedstawienie sytuacji demograficznej w Polsce oraz zaprezentowanie prognoz wysokości świadczeń emerytalnych pochodzących z I i II filara…
Neutralization of acid and base solutions by Reverse Electrodialysis with Bipolar Membranes: a sustainable way to recover energy
2020
The large amount of acidic wastewaters produced in various industrial processes can have a large economic and environmental impact. Companies producing waste acid solutions have to send them to specific sites for the neutralization with alkaline solutions. However, efforts have been devoted so far to promote the acid recovery or its reuse. In the perspective of a more circular manufacturing approach, the present work proposes for the first time the use of the novel Bipolar Membrane Reverse Electrodialysis technology as a viable on-site way to convert the chemical energy associated to the pH gradient of waste acid/base solutions into electrical energy. Bipolar Membrane Reverse Electrodialysi…
Valorization potential of technical lignins from Norway spruce (Picea abies) via pyrolysis
2022
Analytical pyrolysis (Py-GC/MS) on mg-scale of Norway spruce (Picea abies)-derived kraft lignin, ethanosolv lignin, and dried lignin-rich soda-anthraquinone (AQ) black liquors was studied at 500 °C to compare the valorization potential of these materials, focusing on the type and yield of condensable pyrolysis products. Of particular interest was the relatively selective formation of guaiacol (2-methoxyphenol) from the dried soda-AQ black liquors in contrast to the formation of complex phenolic product mixtures from the pyrolysis of the kraft and ethanosolv lignins. It was shown that this finding could be attributed to differences in composition and structure as was assessed by various NMR …
L’Archivio S.A.C.S. del Museo Riso di Palermo. Valorizzazione dello Sportello per l’Arte Contemporanea della Sicilia
2021
L’archivio d’arte contemporanea è un dispositivo culturale attivo volto a selezionare, catalogare, divulgare, esporre e promuovere la creatività artistica in divenire. Queste pratiche di salvaguardia e valorizzazione dei beni artistici sono attività necessarie per la gestione e l’elaborazione del patrimonio culturale, come anche per l’interpretazione del presente. La ricerca sul S.A.C.S., lo Sportello per l’Arte Contemporanea della Sicilia del Museo Riso di Palermo, nasce per valorizzare, attraverso l’approccio integrato della museologia e della fenomenologia dell’arte contemporanea, un giovane Archivio d’arte dedicato ai nuovi creativi siciliani. La tesi, strutturata in tre capitoli, compr…
Chemical Composition of Green Pea (Pisum sativum L.) Pods Extracts and Their Potential Exploitation as Ingredients in Nutraceutical Formulations
2021
Agro-industrial wastes contain a large number of important active compounds which can justify their use as innovative ingredients in nutraceutical products. This study aimed to provide a complete analysis of active molecules, namely (poly)phenols in pea pods water-based extracts, through a UHPLC-Q-Orbitrap HRMS methodology. Data showed that 5-caffeoylquinic acid, epicatechin, and hesperidin were the most relevant (poly)phenols found in the assayed extracts, with a mean value of 59.87, 29.46, and 19.94 mg/100 g, respectively. Furthermore, changes in antioxidant capacity and bioaccessibility of total phenolic compounds (TPC) after the simulated gastrointestinal (GI) process were performed usi…
Polyphenol Characterization and Antioxidant Activity of Grape Seeds and Skins from Sicily: A Preliminary Study
2022
The interest in the consumption of health-promoting foods has led to identifying derivatives of the wine industry as products to increase the functional properties of different foods or to design new functional foods. The main goal of this study is to characterize and valorize byproducts and wastes of Sicilian grapes as new sources of bioactive components, from the perspective of a circular economy and a biorefinery approach. In particular, this research investigated: 1. the total phenolic content and antioxidant activities and 2. the phenolic profiles of free and bound fractions of defatted grape seeds and red grape skins from Sicily. Defatted grape seeds (DGS) and red grape skins (RGSK) a…
LAS CUBIERTAS DE HIERRO DE LA PALERMO LIBERTY - THE IRON ROOFS IN PALERMO’S LIBERTY
2016
The iron architecture spreads in Europe in the nineteenth century, coinciding with the advancement of the steel industry and the development of the extraordinary Art Nouveau period, a movement that analyses the evolution of the modern world, the industrial development, the advances in technology, the new social and cultural needs, to find a new suitable form to meet the new demands of representativeness. In this atmosphere of urban renewal, modern technology plays a primary role, and iron is well-suited to adapt to the new demands of taste that draw inspiration from nature and its organic forms. Many of the iron works of the period have disappeared, destroyed or demolished and others are in…
Power Production from Produced Waters via Reverse Electrodialysis: A Preliminary Assessment
2022
Wastewaters generated by crude oil extraction processes, called “produced waters” (PWs), are complex solutions that contain organic compounds, mainly hydrocarbons, and often exhibit high salinity. The large amounts of PWs represent a global issue because of their environmental impact. An approach widely used in the oil industry is the reinjection of this wastewater into the extraction wells after a suitable treatment. The high salt concentration of such solutions may be used in salinity gradient technologies to produce green electricity. Among these technologies, reverse electrodialysis (RED) is one of the most promising. In this work, the application of RED for energy generatio…
