Il recupero e la messa in valore della Judería di Segovia
2013
The Spanish town of Segovia, World Heritage Site, launched a process of valorisation of its historical centre, supporting conservation and musealisation of monuments as well as encouraging recovery of private houses, particularly in the Judería District. Here, thanks to the Program Área de Rehabilitación de Centro Histórico (ARCH), Segovians were encouraged to go back to the historical center. The Oficina Técnica de Rehabilitación coordinated activities and funding, promoted the participation of owners and entrepreneurs, sensitised citizens on the issues of cultural heritage. The results obtained in the Judería District were so good that ARCH has been adopting in the next district las Canon…
Valorisation of industrial iron oxide waste to produce magnetic barium hexaferrite
2016
Barium M-type hexagonal ferrite (BaM, BaFe12O19) is an immensely important magnetic material, which we have successfully made from the simple valorisation of Fe-rich industrial waste from steel wire drawing, with addition of BaCO3 and heating in air to 1000 degrees C. The optimum ratio of Fe. Ba (producing 86 wt% BaM) was found to be 11: 1 (non-stoichiometric), and secondary phases of alpha-Fe2O3 (non-magnetic) and ZnFe2O4 (poorly antiferromagnetic) were always present. This material consisted of small submicron platelets. A hard magnetic ferrite was produced with Ms=48.6 A m(2) kg(-1) and H-c=211.5 kA m(-1). The highest density was achieved by sintering samples with Fe: Ba ratios of 11: 1 …

Innovative “Green” and Novel Strategies for the Extraction of Bioactive Added Value Compounds from Citrus Wastes—A Review
2017
Citrus is a major processed crop that results in large quantities of wastes and by-products rich in various bioactive compounds such as pectins, water soluble and insoluble antioxidants and essential oils. While some of those wastes are currently valorised by various technologies (yet most are discarded or used for feed), effective, non-toxic and profitable extraction strategies could further significantly promote the valorisation and provide both increased profits and high quality bioactives. The present review will describe and summarize the latest works concerning novel and greener methods for valorisation of citrus by-products. The outcomes and effectiveness of those technologies such a…

La valorisation des compétences de base sur le marché du travail français
2013
D’après la théorie du capital humain, les individus sont rémunérés selon leur productivité, productivité qui dépend elle-même du niveau de diplôme ou du nombre d’années d’études. Mais à l’heure où l’éducation certifiée est discutée comme filtre, qu’en est-il de la valorisation des compétences, notamment de base, sur le marché du travail français ? Alors que de nombreuses recherches ont déjà été réalisées à ce sujet (dans les pays anglo-saxons principalement), aucune n’a encore été conduite sur cette thématique en France. Cette présente étude cherche alors à déterminer, via un modèle d’Heckman en deux étapes, dans quelle mesure l’accès à l’emploi et les salaires sont expliqués par le niveau …
La production et valorisation des compétences sur le marché du travail : des approches néo-classiques à l'économie des conventions
2003
This research starts from human capital theory to study the production and valorization of competences in the labor market. Using the potentials and constraints of the neo-classical approach, the incorporation of other areas of economic science as well as other social sciences contributions are proposed. We believe that the key notions economics of education - human capital and wages, are necessary but they are inadequate to explain the level of individual competence or his level of remuneration. We propose a coherent integration of the theoretical and methodological tools of economics of education as well as of the economics of conventions and economics of human resources. And it includes …
Ephemeral Arts Connection 2011: così le cave di Marsala sono diventate uno spazio scenico unico...
2011
Sintesi dei risultati dell'Ephemeral Arts Connection 2011, 2° workshop internazionale in Sicilia. Le cave dismesse diventano traccia storica di un’attività produttiva peculiare del territorio, memoria dell’intervento dell’uomo sulla natura, scenario naturale da salvaguardare e valorizzare pensando e proponendo usi e fruizioni alternativi. Il workshop ha lavorato a partire dalla riflessione sulle modificazioni del paesaggio e delle sue risorse, sull’intervento dell’uomo quale produttore di eventi spaziali di alta concentrazione che danno luogo a trasformazioni urbane e territoriali di grande rilevanza paesistica. La coscienza del valore ambientale acquisito come bene comune, la proiezione a …
Effects of temperature on post-methanation of digested dairy cow manure in a farm-scale biogas production system.
2003
A post-methanation process that could be adopted at farm-scale, operating at temperatures prevailing in farm manure digester post-storage tanks, was evaluated. Digested manure samples from a farm digester (35 degrees C) and post-storage tank (5-10 degrees C) were incubated in parallel batches at 5-20 degrees C and as reference at 35 and 55 degrees C. Specific methane yields (kg(-1) volatile solids (VS)(added waste)) were 0.20-0.26 m3 at 35-55 degrees C and 0.085-0.09 m3 at 10-20 degrees C for digester material (345 days of incubation) and 0.16-0.21 m3 at 35-55 degrees C, 0.053-0.087 kg(-1) VS(added waste) m3 at 15-20 degrees C and 0.026 m3 at 10 degrees C for post-storage tank material (250…
La chiesa madre di San Cataldo e la sua facciata. Temi di conservazione e valorizzazione
2016
La Chiesa Madre di San Cataldo propone ancora oggi delle questioni relative alla sua trasformazione nel tempo, Nell'ambito dell'architettura barocca siciliana, quest'opera propone ancora il quesito della sua attribuzione che richiede, oltre ad ulteriori studi storico-critici, il mantenimento di ogni traccia o segno di mutamento nel tempo, così come li evidenzia la sua facciata. Ai temi della conservazione dei valori devono correlarsi le questioni impellenti della valorizzazione sua e del contesto in cui la chiesa si colloca.
