Approccio computazionale per la certificazione di strutture aeronautiche in materiale composito
Il processo di certificazione di strutture in materiale composito utilizzate per componenti aero-strutturali è principalmente analitico supportato dall’evidenza dei test a livello di coupon, elementi, sub-componenti, componenti e full-scale. Il processo di certificazione stabilisce che specifiche metodologie di test e particolari controlli dei processi vengano applicati per la qualifica del materiale e dei vari componenti, per verificare la conformità del progetto ai requisiti richiesti. Le procedure (basate su tecniche statistiche) per la caratterizzazione di materiali compositi, comportano l’impegno di una quantità molto grande di risorse ad ogni livello: il criterio di base infatti vuole…
Etude d'une microflore levurienne champenoise
1982
<p style="text-align: justify;">Pendant quatre années consécutives, on a suivi en Champagne, l'évolution de la microflore levurienne depuis la baie de raisin jusqu'au vin clair. Les résultats montrent une influence sensible sur la microflore, d'une part de certains traitements phytosanitaires et d'autre part des opérations liées à la vendange et au traitement des moûts. Grâce à un milieu de culture électif spécial, les auteurs ont amélioré la séparation des colonies de <em>S. cerevisiae</em> et de <em>S. bayanus</em>.</p><p style="text-align: justify;">+++</p><p style="text-align: justify;">For four consecutive years the evolution of yea…
Tentative Reflections on Construction of Assessment Models for Buildings’ Sustainability Certification
2017
All over the word several rating systems have been produced to certificate the sustainability level of buildings. Experts agree on considering sustainability a typical field for multicriteria decision analysis, but buildings’ rating systems do not comply in a consistent manner this assessment approach. Proposals for using classical and hybrid ranking procedures are aimed to quantify the relative attractiveness of buildings, but do not give information on their absolute attractiveness. While several studies propose suitable application of multicriteria decision making techniques for assessing buildings’ sustainability with the purpose of choosing the best solution or obtaining a ranking on a…
The importance of social value in agroecological farms: adjusting the common good balance sheet to improve their sustainable management
2021
Organic farming offers the producers the possibility of focusing on their business while obtaining a competitive advantage. Nevertheless, this is centered in specific activities of the production process, thus only creating environmental value. Therefore, it is not an approach based on sustainability. As a consequence of this, it becomes necessary to enlarge this approach toward people (social value) and profitability (economic value). The objective of this work is to describe a tool based on the Economy for the Common Good model applied to the agroecological sector. We propose to adapt the Common Good Matrix to the characteristics of agroecological farms to offer a useful tool to manage an…
Consumer Preference Heterogeneity Evaluation in Fruit and Vegetable Purchasing Decisions Using the Best–Worst Approach
2019
This study assesses consumer preferences during fruit and vegetable (FV) sales, considering the sociodemographic variables of individuals together with their choice of point of purchase. A choice experiment was conducted in two metropolitan areas in Northwest Italy. A total of 1170 consumers were interviewed at different FV purchase points (mass retail chains and open-air markets) using a paper questionnaire. The relative importance assigned by consumers to 12 fruit and vegetable product attributes, including both intrinsic and extrinsic quality cues, was assessed by using the best&ndash
DNA barcoding for Arecaceae and Fabaceae species identification of two plant collections
2021
DNA barcoding is a well-known technique that enable species identification by using universal DNA sequences from a small fragment of the genome. In this work, the effectiveness of DNA barcoding approach was evaluated in order to identify different taxonomic groups among two families (Arecaceae and Fabaceae) from two flowering plant collections: some were economically important taxa from nursery production and Mediterranean plants with ornamental attitude for possible new introduction. Three chloroplast DNA barcode regions (matK, rbcL and trnH-psbA) proposed by the Consortium for the Barcode of Life (CBOL) were tested in 22 Arecaceae species and in eight Fabaceae species, including Ceratonia…
Contributo per una visione contemporanea dell’azienda agricola: tra sostenibilità e sfide del mondo digitale
2023
Le sfide che l’umanità sta affrontando e da cui dipende la sopravvivenza del pianeta, il diffondersi nell’ambito dell’attività agricola di tecnologie digitali sempre più avanzate e la necessità di adottare un approccio sostenibile che preservi le risorse a tutela delle generazioni future hanno condotto l’azienda agricola a cambiare gradualmente volto. Questo libro mira a contribuire a un’aggiornata riflessione sul ruolo dell’imprenditore agricolo e dell’azienda da lui condotta, osservandone l’organizzazione e composizione alla luce delle regole che oggi la disciplinano e guardando alle innovazioni necessarie a garantire il raggiungimento dei pressanti obiettivi climatici e ambientali verso …

Economical Incentives and Systems of Certification for the Production of Electrical Energy from Renewable Energy Resources
2007
In order to succeed in observing the international agreements undertaken in the Kyoto agreement protocol, today it is necessary to increase the electrical energy production from renewables energy resources (RERs). In this paper a complete description of the Italian incentive systems for the production of electrical energy from photovoltaic (PV) and other RERs is done. Moreover, some considerations about the effects of the incentive actions on the wide spread of RERs to produce electrical energy are reported; particular attention is paid in the economical analysis related to PY and wind systems.
Transferability to LDC of Some European standards concerning the environmental certification of products and services
2002
Goal and Scope. Western developed countries (DC) are currently involved in an important process of releasing new rules and standards devoted to the environmental certifications of urban systems, in order of accomplishing the requirements established by the international protocols (Kyoto, among them), aimed at the reduction of greenhouse gases emitted in the atmosphere and at the limitation of the environmental impact as well. Within this frame, the European Union is giving a rising importance to the so-called 'Integrated Product Policy' (IPP), that is an integrated approach of the environmental policy, aiming to an improvement of the environmental performance of products and services during…
