Una ipotesi di green design per la “valori-naturazione” di Caltabellotta
2020
Questo studio individua nella “valori-naturazione” del centro di Caltabellotta un campo privilegiato di sperimentazione architettonica e tecnologica. La ricerca approfondisce l’uso dell’involucro verde come sistema di possibile caratterizzazione dell’immagine urbana volto anche a riequilibrare le discontinuità causate da fenomeni di degrado edilizio. Nei vuoti urbani del borgo vengono “innestate” nuove centralità spaziali che faranno da connettori di sviluppo ecologico affinché Caltabellotta possa candidarsi a green city della Provincia di Agrigento, esplorando scenari ancora poco praticati in questo contesto. In tale ottica si studiano le specificità del tetto giardino e del giardino verti…
Palermo Blue/Green Gateway. Nove porte per la knowledge city
2015
Il saggio esplora le trasformazioni della linea di costa dell'area metropolitana di Palermo e traccia linee ed indirizzi di trasformazione legate alla rigenerazione di nove porti intesi come nuove porte di accesso alla città stessa. Il saggio presenta l'ipotesi di trasformazione e rigenerazione urbana ed architettonica che l'autore ha elaborato in occasione della candidatura di Palermo a Capitale Europea della Cultura per il 2019, in qualità di membro della cabina di regia e del coordinamento scientifico della candidatura. Lo scritto porta avanti una ipotesi teorica e di ricerca fondata sulla postproduzione urbana e architettonica e sulla knowledge city come tema trainante per la rigenerazi…
Grounds and Challenges for Implementing a Circular Economy in the European Road Transport Sector
2017
Environmental challenges, especially in the form of resource depletion, pollution and greenhouse gas emission, are very important challenges for the socio-economic development. For this reason, the concept of a circular economy has been developed and is being implemented in different areas. In 2015, the European Union adopted the Circular Economy Package consisting of an “EU Action Plan for the Circular Economy”, presenting a set of actions aimed at achieving objectives of the circular economy in Europe. The goal of the paper is to describe and discuss key challenges facing implementation of the concept of the circular economy in the European road transport sector. First, the concept of a c…
Configurations of the Interactive Use of Environmental Management Control
2013
This paper explores the use of interactive environmental management control. In order to do this, a theoretical model is designed drawing on the framework of Simons (1995) and instrumental stakeholder theory. This model defines three dimensions of interactive control: forms of interactivity (vertical, horizontal, external), frequencies of interactivity (high, medium, low) and decision levels (strategic, tactical, operational). Four typical configurations emerge from application of the model to empirical data from ten case studies: eco-designers, eco-institutionals, eco-managers and eco-educators. These configurations show the diverse roles of interactive environmental management control in …
The Valencia Eustress-Distress Appraisal Scale (VEDAS): Validation of the Italian Version
2018
© 2018 by the authors. The aim of this study is to validate the Italian version of the Valencia Eustress-Distress Appraisal Scale (VEDAS). Two hundred and thirty-two Italian workers were involved in the study. Dimensionality, reliability, and concurrent validity were analyzed. Confirmatory factor analysis supported a four-dimensional structure. In addition, the Italian version of the scale showed good internal consistency and validity. The results indicate that the Italian version of the VEDAS is a valid instrument for measuring eustress and distress appraisal in the Italian context. ispartof: SUSTAINABILITY vol:10 issue:11 status: published
Long-term survival of pathogenic and sanitation indicator bacteria in experimental biowaste composts
2005
ABSTRACT For economic, agricultural, and environmental reasons, composting is frequently used for organic waste recycling. One approach to limiting the potential risk from bacterial food-borne illnesses is to ensure that soil amendments and organic fertilizers are disinfected. However, more knowledge concerning the microbiological safety of composted substrates other than sludge and manure is necessary. Experimental in-vessel biowaste composts were used to study the survival of seeded Listeria monocytogenes , Salmonella enterica subsp. enterica serotype Enteritidis, and Escherichia coli . Four organic waste mixtures, containing various proportions of paper and cardboard, fruits and vegetabl…
Comparative study onSalmonellaisolation from sewage-contaminated natural waters
1984
Alcaide, E., Martinez, J.P. & Garay, E. 1984. Comparative study on Salmonella isolation from sewage contaminated natural waters. Journal of Applied Bacteriology56, 365–371. A comparative study of five factors influencing the isolation of salmonellas from sewage-contaminated natural waters was carried out. The effect of pre-enrichment in buffered peptone water was compared with single-step enrichment in NR10 broth incubated at 43dC. A modification of NR10 has been compared with the original composition. Bismuth sulphite agar (BSA), Hektoen enteric agar (HE) and brilliant green agar (BGA) have been used as plating media. Other factors considered have been temperature of the water and sampling…
Toward a European Eco-label brand for residential buildings: Holistic or by-components approaches?
2011
The Eco-label scheme is becoming ever more important in the environmental certification of products and services, especially in light of the recent ambitious aim of containing greenhouse emissions and improving the efficiency of utilizing energy sources. A recently-introduced hypothesis concerns the European Eco-label scheme relating to buildings, in the awareness that the construction industry is of primary importance to the whole economic and social life of states. This scheme should adopt an integrated approach to environmental problems and include construction, day-to-day management, and the possible disposal of building materials, throughout the life cycle of the building. In addition,…
Seismic properties across an amphibolite- to greenschist-facies strain gradient (Neves area, eastern Alps, Italy): New considerations for shear zone …
2021
Abstract Detecting the presence and geometry of crustal shear zones by geophysical methods relies on our understanding of the intrinsic parameters controlling the seismic properties of these deformed rocks, over the range of pressure-temperature conditions expected in the Earth's crust. To this end, we aimed to track changes in P-wave propagation velocity (VP), anisotropy (AVP) and S-wave splitting (AVS) across a natural shear zone using experimental and electron backscatter diffraction methods. Five samples were collected across a meter-scale shear zone developed under amphibolite- to greenschist-facies in the Neves metagranodiorite (Tauern Window, Eastern Alps). With increasing strain, se…
Yeast vectors for the integration/expression of any sequence at theTYR1 locus
2007
We have constructed new yeast vectors for targeted integration and conditional expression of any sequence at the Saccharomyces cerevisiae TYR1 locus which becomes disrupted. We show that vector integration is not neutral, causing prototrophy for tyrosine and auxotrophy for the vector's selectable marker (uracil or leucine, depending on the vector used). This feature allows a double screening of transformed yeast cells, improving the identification of colonies with the desired chromosomal structure. The GAL10 gene promoter has been added to drive conditional expression of cloned sequences. Using these vectors, chromosomal structure verification of recombinant clones is no longer necessary, s…
