Ritratti di architettura: rappresentazioni e rilievi di edifici del Trecento (XVIII-XIX secolo)

2020

Il contributo presenta alcune fonti iconografiche (un dipinto, incisioni e disegni) appartenenti alle collezioni della Galleria Regionale della Sicilia di Palazzo Abatellis, databili tra XVII e XIX secolo, che ritraggono architetture trecentesche siciliane. Frammento di un vasto patrimonio visuale, che spazia dalle vedute urbane e di paesaggio, al disegno di prospetti ed elementi architettonici, allo studio dei dettagli ornamentali, l'iconografia in esame rientra nel fenomeno delle “riscoperte” dell’architettura medievale siciliana, nel quale si inseriscono anche alcune delle più significative opere trecentesche, direttamente o indirettamente legate all’età dei Chiaromonte.

Measuring the CO2 shadow price for wastewater treatment: A directional distance function approach

2015

Abstract The estimation of the value of carbon emissions has become a major research and policy topic since the establishment of the Kyoto Protocol. The shadow price of CO2 provides information about the marginal abatement cost of this pollutant. It is an essential element in guiding environmental policy issues, since the CO2 shadow price can be used when fixing carbon tax rates, in environmental cost-benefit analysis and in ascertaining an initial market price for a trading system. The water industry could play an important role in the reduction of greenhouse gas (GHG) emissions. This paper estimates the shadow price of CO2 for a sample of wastewater treatment plants (WWTPs), using a param…

Carlo Scarpa. Una [curiosa] lama di luce, un gonfalone d’oro, le mani e un viso di donna : riflessioni sul processo progettuale per l’allestimento di…

2020

Seconda edizione aggiornata e ampliata febbraio 2020. L’organizzazione spaziale di tutta la Galleria Regionale di Palazzo Abatellis è un luogo di mediazioni complesse fra l’impegno progettuale scarpiano, il senso di misura e di armonia complessiva e le istanze del curatore Giorgio Vigni. Il volume, nella sua struttura, cerca di far comprendere il collegamento fra il luogo e il processo progettuale del “fare scarpiano”, scartando la cronologia dell’intervento stesso con riflessioni che riguardano la strategia dei percorsi, e forse svelano un possibile messaggio in codice. Si tratta di una ricognizione mirata, la cui narrazione è ricomposta anche grazie ad alcuni indizi (rinvenuti durante lo …

Carlo Scarpa e la sala del dubbio di palazzo Abatellis

2016

Questo articolo descrive, da un disegno di studio e da foto d'archivio, la sala del dubbio in divenire al processo di progettazione. E' uno sguardo alla realizzazione di Scarpa con la consapevolezza che le forme e gli allestimenti di palazzo Abatellis, stabiscono alla scala di dettaglio; "raccontare" di possibili somiglianze tra il dispositivo e le relazioni spaziali che si instaura con gli occhi del visitatore. This paper describes, from a study design and the photo archive, the challenge of the lost set-up in the making that the design process. It's a look at the making Scarpa with the knowledge that forms and exhibitions for Abatellis palace, established the scale of detail; "recount" of…

Electrochemical abatement of chloroethanes in water: Reduction, oxidation and combined processes

2010

An electrochemical route, based on the anodic oxidation to carbon dioxide coupled with the cathodic reduction to de-halogenated hydrocarbons, was proposed for the treatment of waters contaminated by chloroethanes. The electrochemical abatement of two model compounds, namely 1,2-dichloroethane and 1,1,2,2-tetrachloroethane, was carried out by cathodic reduction at silver, anodic oxidation at boron doped diamond (BDD) and combined processes. The anodic oxidation gives rise to a high abatement of the concentration of both these compounds and of COD. The reduction of 1,1,2,2-tetrachloroethane proceeds also with high abatement but with the formation of some halogenated intermediates and final pr…

Marginal abatement cost of carbon dioxide emissions in the provision of urban drinking water

2021

Abstract Reducing greenhouse gas emissions is a major challenge faced by cities seeking to improve their environmental sustainability. Doing so requires a good understanding of the costs associated with lowering emissions and factors that may influence this cost. This study estimated the marginal abatement cost of reducing both direct and indirect CO2 emissions in the provision of drinking water by several water companies in England and Wales. The results indicated that during the years 2013–2018, the average cost to the English and Welsh water industry to prevent 1 kg of CO2 emissions was 0.264₤ which was equivalent to 61% of the price of the delivered drinking water The results of the Mor…

Biological Nutrient Removal and Fouling Phenomena in a University of Cape Town Membrane Bioreactor Treating High Nitrogen Loads

2013

The behavior of a University of Cape Town (UCT) membrane bioreactor (MBR) system was investigated for use in biological nutrient removal from real wastewater. The pilot plant was in operation for a period of 165 days, during which an extensive data gathering campaign was conducted. The pilot plant was started up by inoculating it with activated sludge from a nearby wastewater treatment plant, and it was fed by real municipal wastewater characterized by high organic nitrogen concentrations attributable to discharges from industrial wastewater and sporadic landfill leachate. Carbon and biological nutrient removal processes, a sludge production process, and a membrane fouling mechanism were an…
