Earth Construction: The Mechanical Properties of Adobe with the Addition of Laponite
2015
The contribution describes testing of compression strength, flexural strength and abrasion resistance of adobe made up of soil, water and sand (AS), soil, water, sand and straw (ASP), soil, water, sand and laponite nanoparticles (ASN). Embodied energy in materials presents an increasingly high percentage of the energy spent in the whole life cycle of a building. The same applies for carbon dioxide (CO2). Therefore, the development of new sustainable construction materi- als with lower embodied energy and lower CO2 emissions is needed. The use in construction of the brick made from soil, water and sand or straw, called adobe, boasts a millenary tradition and in recent years there has been re…
Sustainable mobile vertical partition / Pannello verticale mobile sostenibile
2016
Pannello per realizzare partizioni mobili verticali, costituito da: un telaio principale in legno con funzione strutturale (a); una stuoia di canne schiacciate e intrecciate con funzione di chiusura (b); una cornice e un sistema di listelli in legno con funzione di supporto (c); uno strato di intonaco in terra cruda con funzione di finitura (d), posto su un lato della stuoia di canne (b).

Family Council From A Cultural Approach: the case of eastern european countries
2021
The family council is a formal mechanism of the family governance in family businesses that aims to give a voice to all members of the family, and to unify the interests of all members. These interests are identified with the purpose of the family, necessary to achieve a long-term legacy, and the sustainability of the company. However, the establishment of the family council is a topic that is still at an incipient stage, both in the literature and for practitioners, so our contribution advances the understanding of family governance within the sphere of family businesses culture and context. For that purpose, we rely on two cultural indexes widely accepted in the literature. We have taken …
Ultrastructural changes of the oenocytes of Gryllus bimaculatus DEG (Saltatoria, Insecta) during the moulting cycle
1974
1. The oenocytes of Gryllus bimaculatus are characterized by an abundant smooth-surfaced ER (ATER). In spite of the great cell size the plasma membrane never shows extensive infoldings during the moulting cycle. In addition to mitochondria there are very large numbers of microbodies containing peroxidase but apparently not uricase. Within the second part of the instar the microbodies lie along the clefts which run through the whole cell. 2. The following changes are observed in the course of a moulting cycle: Immediately after hatching the ATER is scarcely developed, some liposomes are located within areas of ATER disappearing some hours later. 20 hours after emergence glycogen deposits app…
The Value of Organic plus. Analysing Consumers’ Preference for Additional Ethical Attributes of Organic food Products
2023
AbstractOrganic Plus attributes strengthen the sustainability of the organic products and differentiate them from the ‘conventionalized’ organic ones. Products with Organic Plus attributes seem appreciated by organic consumers. However, research on consumers’ preference for Organic Plus is still scarce, leaving gaps in the understanding of the consumers’ characteristics of organic products with Plus attributes. In order to enrich the knowledge of consumers’ preference for organic products with Plus attributes, the present study aims to achieve three Objectives: (1) identifying which Plus attributes, among fair prices to local farmers, integration of people with disabilities and eco-friendli…
Take away antispreco. Per un nuovo stile di vita - WASTE-FREE TAKEAWAY FOR A NEW KIND OF LIFE STYLE
2008
Il testo nasce per promuovere e sensibilizzare il tema dei consumi, dei comportamenti responsabili e sostenibili. I nuovi progetti propongono nuovi packaging progettati per portare a casa il cibo e il vino non finiti al ristorante ed essere nuovamente apprezzati il giorno successivo, accettando senza imbarazzo un'abitudine in uso nei ristoranti di alcuni Stati Europei e degli Stati Uniti. This paper is focused to promote the issue of the consumption and of the responsible and sustainable behaviours. The new projects propose new packaging designed to bring home the food and the wine not finished at the restaurant, that can be appreciated again the next day, accepting without embarrassment th…
Development of eco-friendly processes for the synthesis of biobased solvents and organocatalysts
2018
Oxazolidinones are promising compounds for industrial applications, but nowadays there is not convenient method to produce them on large scale, because of the use of reactants and metallic catalysts harmful for health and environment. A new synthesis method of these compounds was thus elaborated using aminoalcohols and diethyl carbonate. This reaction is catalysed by a biobased imidazolium hydrogen carbonate which is produced by an electrochemical pathway in order to reduce its impact on the environment.This oxazolidinones synthesis method was then applied to the synthesis of a biobased oxazolidinone. To achieve this, an aminoalcohol synthesis was realised, and its structure was established…
A Holistic Approach to Education for Sustainability: Ecofeminism as a Tool to Enhance Sustainability Attitudes in Pre-service Teachers
2021
Abstract To achieve an effective Education for Sustainable Development (ESD), teachers should possess appropriate sustainability attitudes to transmit those values to their future students. In this article, a holistic educational intervention around the ecofeminist movement is described and its impact on the sustainability attitudes of 188 pre-service teachers is assessed. The quantitative results with a validated questionnaire reveal an initial high level of sustainability awareness and a statistically significant increase in the environmental dimension after the educational intervention. In addition, the qualitative analysis of the stories and activities for children prepared by the stude…
A Holistic Vision of Smart Cities: An Opportunity for a Big Change
2016
The depletion of energy resources on the one hand, and the population growth on the other, forced the society at all levels (local, national and international) to turn its attention to the identification of new forms of protection of the environment and the waste reduction for a new eco-sustainable way of living. The process of massive urbanization already in place, exacerbated by the movement of large masses of people in search of a more human form of life, is putting severely under test the livability within our cities, bringing out the inefficiency of existing management and organization models. Daisaku Ikeda said: “Certainly, the density of urban populations means that problems are conc…
Agder as Mutual Competence Builders: Developing Sustainability as a Competitive Advantage
2015
In this chapter, Agder as Mutual Competence Builders: developing sustainability as a competitive advantage, Karen Landmark, Marianne Rodvelt and Stina Torjesen provide a discussion of companies in the Agder region which are organised in the Eyde-network, and how they have developed a common sustainability agenda in co-operation with the university. The chapter shows how this is followed up by organising an Eyde-school as vocational training in co-operation with the university.
