Perspectives of the encapsulation technology in the nursery activity of Citrus
2007
The genetic and phytosanitary certification has to guarantee the quality of the propagation material also in Citrus. Traditional methods can be assisted by the techniques of in vitro culture, which are fundamental for the mass production of high quality plants. The encapsulation technology represents an innovative tool to combine the advantages of micropropagation with handling ease, storability, reduced size of the propagules, mechanization potentiality, transportability of the gamic seeds. In this work somatic embryos obtained from in vitro anther culture of the cultivar Mandarino Tardivo di Ciaculli (Citrus reticulata Blanco) were encapsulated in a sodium alginate matrix and synthetic se…
Old or new occupants of energy rehabilitated buildings. Two different approaches for hierarchizing group of buildings
2017
Abstract Public Administrations are frequently entitled to intervene in building stocks with energy rehabilitation actions. Unfortunately, the monetary budget at their disposal is generally limited and, consequently, a prioritization criterion is needed to optimize its allocation. The classification of the building energy performance is increasingly used by Public Administrations for this purpose. Here we argue that a proper prioritization criterion should depend upon the potential subjects to which the rehabilitated buildings are given back. If the energy rehabilitation is conducted on buildings that will be assigned to new dwellers, it would be preferable to use the energy class – which i…
Application of Environmental Management Systems (EMS) to Natural Parks and reserves
2006
Natural parks and reserves have to face problems concerning the conservation of their natural resources. Citizens and firms often perceive the institution of new protected areas more as a bind or a restriction to their activities than an added value of the territory. Following the principles of sustainable development, it is necessary to integrate the environmental protection with the needs of neighbouring urban areas and production sites. The implementation of an Environmental Management System (EMS) according to international standards (ISO 14001, EMAS) can support the Park administration in their complex management activities. This paper analysed the criticisms related to the application…
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…
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…

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…
