Pienamente conservare per pienamente fruire: il paradigma della Vucciria di Palermo nel Progetto I-Access

2021

Già dal nome la città di Palermo rivela una delle sue peculiarità più significative, ovvero la capacità di accogliere: dal greco «Pan ormos» - tutto porto. In generale, consapevole della vocazione di Palermo, il mercato della Vucciria è stato scelto per illustrare i contenuti del Progetto Interreg Italia-Malta, I-Access di Implementare l'accessibilità alla fruizione e alla conoscenza del centro storico urbano e per le somiglianze e le differenze riscontrate nel La Valletta e Palermo. Il progetto I-ACCESS ha verificato un metodo per promuovere l'accessibilità in senso culturale e fisico e questa esperienza può essere ripetuta in altri centri storici. La conoscenza della realtà materiale del …

Landfill Culture: Some Implications to Degrowth

2016

To some extent, waste is just one more sign of the unsustainability of growth. Waste from industrial and socio-economic metabolism must be understood as any unusable material left over after a job, function or operation has been completed, which however, retains the ability to disrupt natural systems and interfere with them as one of its inherent properties. As part of such waste, Municipal Solid Waste (MSW) represents the unusable (or underused) and rejected fraction of the material resources mobilized by the sophisticated urban and/or industrial ecosystem. Although the volume of MSW is relatively small compared to other waste types, it is increasingly important as a result of its steady r…

The state of water resources in major mediterranean islands

2014

This work analyses the state of water resources in six Mediterranean islands: Corsica, Crete, Cyprus, Mallorca, Malta and Sicily. The analysis is focused on the prevailing social, economic and hydroclimatological characteristics of these islands in order to identify the main common features affecting water availability, demand and use. A detailed analysis of the state of water resources in all the considered islands has been carried out. A background of current conditions relating to freshwater availability, quality and use has been established. Different strategies to face water scarcity and enhance water quality in theislands have been assessed in a context of climate change which is a co…

The Influence of Seasonality on the Economic Efficiency of Wastewater Treatment Plants

2010

Many tourist areas are often characterized with seasonal water demand. The influence of seasonality on water management is more intensive in the context of water scarcity. Thus the use of so-called non-conventional water resources in these areas becomes a key aspect. In this sense, efficient performance, both in technical and cost terms, favors water reuse possibilities and, therefore, increases the supply of non-conventional resources. In tourist areas, seasonality is a determining factor in the efficiency of wastewater treatment plants (WWTPs) as these are operating at full capacity only during the summer season while the rest of the year they have under-utilization problems. Using the Fr…

ECONOMIC AND TECHNICAL EFFICIENCY OF WASTEWATER PLANTS: A BASIC REQUISITE TO THE FEASIBILITY OF WATER REUSE PROJECTS

2006

The water reuse could be considered essential both from a social and also an environmental and health point of view. In light of the growing importance of water reuse as an alternative source of water resources in many regional areas, the objective of this paper is to analyse the efficiency of wastewater treatment plants. Efficient performance, both in technical and economic terms favours reuse possibilities and, therefore, increases the water supply. An analytical benchmarking methodology based on non-radial measures gives us an efficiency indicator for each input considered in the wastewater treatment process. These indicators, obtained by means of mathematical programming techniques, are…

Sources optiques infrarouges impulsionnelles ultra-courtes et spectralement ultra-larges générées par effet Raman dans les fibres creuses

2019

Gas-filled Hollow-Core Photonic Crystal Fibers (HC-PCF) are efficient tools regarding ultra-wide and coherent optical frequency combs by Stimulated Raman Scattering (SRS). Coherence is reached thanks to highly transient regime as it allows amplification, from quantum to macroscopic level, of a unique spatial and temporal mode (TSM). This results in the generation of Stokes waves with a well-determined phase. The present work details on which time scale coherence can subsist, between two consecutive pulses. The possibility of making a new kind of mode-lock is studied. Then the extreme versatility of gas-filled HC-PCF is illustrated by presenting different kind of new laser sources, exploitin…

Semantic Web Enabled Web Services: State-of-Art and Industrial Challenges

2003

Semantic Web technology has a vision to define and link Web data in a way that it can be understood and used by machines for automation, integration and reuse of data across various applications. Ontological definition of every resource as it is assumed in Semantic Web, along with new techniques for semantics processing and new vision Intelligent Web Services is expected to bring Web on its new level. At present, Web Services technology is stressed by the search of a right way for further development. Combination of Semantic Web and Web Services concepts may address many of difficulties of existing technology. It is not a question of whether Semantic Web is coming or not, but a question of …

Persistence of a mixed lactic acid bacterial starter culture during lysine fortification of sourdough breads by addition of pistachio powder

2020

Abstract Pistachio powder was added to flour or semolina to evaluate its contribution to increase the amount of lysine in bread. Bread production was carried out by sourdough technology using a selected 3-species (Lactobacillus sanfranciscensis/Leuconostoc citreum/Weissella cibaria) lactic acid bacterial (LAB) starter culture. All sourdoughs were subjected to a long-time fermentation (21 h) and showed levels of LAB around 109 CFU/g, indicating the suitability of pistachio powder for lactic fermentation. Yeasts were also detected, in particular in semolina trials. MiSeq Illumina technology was applied to investigate the bacterial composition of sourdoughs evidencing a different distribution …

Diversity and technological potential of lactic acid bacteria of wheat flours

2013

Abstract Lactic acid bacteria (LAB) were analysed from wheat flours used in traditional bread making throughout Sicily (southern Italy). Plate counts, carried out in three different media commonly used to detect food and sourdough LAB, revealed a maximal LAB concentration of approximately 4.75 Log CFU g−1. Colonies representing various morphological appearances were isolated and differentiated based on phenotypic characteristics and genetic analysis by randomly amplified polymorphic DNA (RAPD)-PCR. Fifty unique strains were identified. Analysis by 16S rRNA gene sequencing grouped the strains into 11 LAB species, which belonged to six genera: Enterococcus, Lactobacillus, Lactococcus, Leucono…
