Removal of trivalent chromium from tannery waste waters using bone charcoal
2002
International audience; The ability of bone charcoal to remove Cr(III) from aqueous solutions by adsorption has been investigated. The adsorbent used was first characterised and then the adsorption was studied as a function of time and amount of charcoal. Tests were carried out with synthetic solutions whose Cr concentrations (500 mg L-1) were similar to those found in some effluents of Moroccan tannery industries. Cr removal efficiencies higher than 90% were obtained at pH 3.5 using 3 g of bone charcoal and a stirring time of about 30 min. Results of Cr removal by all sieved fractions of bone charcoal had shown the same interesting capabilities for Cr(III) retention. The cross interference…

URBAN RESILIENCE AND WASTE MANAGEMENT: PROPOSALS OF NEW INFRASTRUCTURES FOR URBAN AREAS AND BUILDINGS
2015
La produzione ingente di rifiuti, quale conseguenza di costumi di vita volti allo spreco, rende vulnerabili i sistemi urbani che possono essere sottoposti, in casi emergenziali, a pressioni eccezionali e incontrollate con situazioni prossime al collasso. Un’opportuna e corretta gestione integrata dei rifiuti contribuisce alla resilienza dei sistemi urbani. Perciò si rendono necessarie la pianificazione e la progettazione di nuovi servizi e l’individuazione/integrazione di spazi e dotazioni tecnologiche per incentivare la popolazione a effettuare la raccolta differenziata in modo corretto e costante. Si presentano gli esiti di uno studio svolto in un piccolo centro siciliano. Partendo dalle …
Le città tardobarocche del Val di Noto nella World Heritage List dell'UNESCO
2008
Svolta su incarico della Soprintendenza dei Beni Culturali e Ambientali di Siracusa, nell'ambito di un progetto POR finanziato da fondi europei, la monografia ha lo scopo di svolgere un esaustivo escursus storico-critico dedicato alle otto città del Val di Noto (Caltagirone, Catania, Modica, Militello Val di Catania, Noto, Palazzolo Acreide, Ragusa, Scicli), inserite nel 2002 nella World Heritage List dell'UNESCO, come parti costituenti il sito "Le città tardo-barocche del Val di Noto". Lo studio è sostanzialmente diviso in due parti. La prima è dedicata allo svolgimento degli eventi storici e artistici che interessarono complessivamente l'area della Sicilia colpita dal terremoto del 1693, …
Global trends in a fragile context : public–nonpublic collaboration, service delivery and social innovation
2020
PurposeThis study aims to enhance the understanding of the nature of collaboration between public and nonpublic actors in delivering social services and achieving social innovation in a fragile context, with an emphasis on the role of civil society organisations (CSOs). The paper focuses on Bosnia and Herzegovina, a Southeastern European country which has faced a turbulent post-conflict transition and experienced challenges in its social welfare policy and practice.Design/methodology/approachThis study uses institutional theory, particularly new institutionalism and institutional networking, as a lens through which to understand public and nonpublic collaboration and social innovation withi…
A Proposal for an Automatic Stabilizer in Social Justice
2019
Abstract Generally, social justice has two sides which are intercorrelated and inter-dependend: a) constitutive social justice (for example, the so called commutative social justice); b) regulative social justice (for example, the so called distributive social justice). The paper approaches the regulative social justice, more exactly, an automatic mechanism to get it. To this end, an automatic stabilizer to provide distributive social justice, according to the Rawlsian principle of difference. Such an automatic stabilizer is grounded on the wealth, more precise, on the share of the wealth which is not invested in order to benefit to the more disadvantaged class of the society. Paper does no…
What distance do university students walk and bike daily to class in Spain
2016
Abstract Introduction Physical activity levels are low in the general population and these levels decrease from childhood to adolescence, as well as from adolescence to adulthood. Active commuting (AC) is an opportunity to increase the physical activity levels. The distance between home and destinations is a main correlate of AC; however, the distance that university students walk or cycle to university is unknown. Methods Participants self-reported their modes and time of commuting to and from university in a questionnaire, and the main mode of commuting was identified. Moreover, they reported their home address, and the Spanish version of Mapquest software was used to measure street-netwo…
Effects of tobacco cigarettes, e-cigarettes, and waterpipe smoking on endothelial function and clinical outcomes
2020
Abstract Tobacco smoking is a leading cause of non-communicable disease globally and is a major risk factor for cardiovascular disease (CVD) and lung disease. Importantly, recent data by the World Health Organizations (WHO) indicate that in the last two decades global tobacco use has significantly dropped, which was largely driven by decreased numbers of female smokers. Despite such advances, the use of e-cigarettes and waterpipes (shisha, hookah, narghile) is an emerging trend, especially among younger generations. There is growing body of evidence that e-cigarettes are not a harm-free alternative to tobacco cigarettes and there is considerable debate as to whether e-cigarettes are saving …
Incrementally Assessing Cluster Tendencies with a~Maximum Variance Cluster Algorithm
2003
A straightforward and efficient way to discover clustering tendencies in data using a recently proposed Maximum Variance Clustering algorithm is proposed. The approach shares the benefits of the plain clustering algorithm with regard to other approaches for clustering. Experiments using both synthetic and real data have been performed in order to evaluate the differences between the proposed methodology and the plain use of the Maximum Variance algorithm. According to the results obtained, the proposal constitutes an efficient and accurate alternative.
Co-operative wineries: Temporal solution or efficient firms? The Spanish case during late Francoism, 1970–1981
2015
Part of economic theory has regarded co-operative firms as useful tools for dealing with market failures during periods of economic contraction, but also as suffering severe efficiency problems during periods of growth. The main aim of this article is to test this hypothesis in the case of Spanish co-operative wineries during the years of late Francoism. In order to do this, the balance sheets of 75 co-operative firms from the 1970s have been subject to financial-ratio analyses. The main conclusion is that these firms were inefficient due to their excessive financial debt. The Spanish Francoist government promoted their creation and granted financial aid – for their value as social and econ…
