Industrial waste heat: Estimation of the technically available resource in the EU per industrial sector, temperature level and country

2018

Abstract Industrial waste heat is examined in EU countries, focusing on the amount that can be recovered and exploited, referred to as technical potential of waste heat. An alternative methodology is proposed here, which is based on waste heat fractions derived from a detailed study of the UK industry from the period 2000–2003. These fractions express the part of heat consumption that is wasted and is possible to be recovered. The waste heat fractions have been calculated in this work for each main industrial sector and temperature level. The methodology initially includes the adjustment of waste heat fractions from each industrial sector from the UK industry to the conditions of the differ…

Research and Projects for the Recovery of the “Tifeo” Power Station in Augusta, Sicily

2016

The buildings of the Tifeo Augusta Power Station (SR) significantly tell us, even today, the history of the Sicilian industrial dream at the end of the Fifties. However, with the passing of time, it revealed the underlying contradictions still present today in Augusta together with polluting and oppressive petrochemical plants built during those times. Regardless of any recovery theory about the Augusta Power Station, it is clear that an open and multidisciplinary look cannot be ignored, locating the power station in the actual and future setting of the vastest territory in which it is sited. The past, the present and, of course, the future of the Augusta area are tightly connected to the s…

Was ist neu in der kardiopulmonalen Reanimation?

1994

A strong consensus was reached for several changes in the guidelines for cardiopulmonary resuscitation (CPR) and emergency cardiac care (ECC) in the 1992 conference on CPR and ECC held by the Emergency Cardiac Care Committee of the American Heart Association. These new recommendations, together with differing recommendations of the European Resuscitation Council, are described. An unresponsive person with spontaneous respirations should be placed in the recovery position if no cervical trauma is suspected. Compared with endotracheal intubation, other airway-protecting devices such as combination esophageal-tracheal tubes are of minor acceptance. During ventilation, the time for filling the …

Il confronto delle idee. Visioni progettuali per un recupero possibile (The comparision of ideas. Design concepts for a possible recovery)

2016

Il saggio dà conto e avanza una sintesi dell'esperienza di ricerca attuata nell'ambito del Dipartimento di Architettura dell'Università di Palermo e finalizzata all'individuazione di possibili scenari e di visioni progettuali per il recupero del complesso della centrale termoelettrica "Tifeo" di Augusta, significativa opera di Giuseppe Samonà. La ricerca sottolinea come progetto architettonico e progetto di paesaggio risultino (anche in questo caso) inscindibili e legati da stringenti refluenze reciproche: restauro dell’edificio e “restauro” del paesaggio si presentano come azioni concorrenti e interagenti, mirate verso un unico obiettivo comune, che può attuarsi solo attraverso una rifless…

Re_Power station: una ricerca per la Centrale di Augusta

2016

Lo scritto descrive le modalità dell'impostazione data al lavoro di ricerca sulla centrale "Tifeo" di Augusta, condotto nell'ambito del Dipartimento di Architettura dell'Università di Palermo e di concerto con l'ENEL. La ricerca era finalizzata alla definizione di una ricerca di base per lo studio di fattibilità del recupero della Centrale di Augusta, con l’obiettivo di definire alcuni possibili scenari progettuali entro cui intervenire, anche attraverso specifici progetti di architettura. L’ipotesi di lavoro attorno a cui ci si è mossi, che si è fondata sull’impostazione metodologica assunta negli anni dal Dottorato di ricerca in Architettura/Progettazione Architettonica, ha visto il proge…

Re_Power station. Reuse of Augusta Power Station

2016

Raramente accade che il recupero di un edificio possa riassumere su di sé tutta l’emblematicità, anche simbolica, di un reale cambio di paradigma rispetto a scelte contraddittorie fino ad oggi compiute su un territorio; ma ciò può accadere, con piena evidenza, nel caso della Centrale termoelettrica ENEL “Tifeo” di Augusta (SR). Il suo recupero si presenta infatti come uno dei casi studio tra i più interessanti nel panorama internazionale, per le dinamiche che questo condensa, per le nuove visioni strategiche e per i mutamenti di senso che attorno ad esso si possono prefigurare. Il libro raccoglie i risultati della ricerca condotta nell’ambito del Dottorato di ricerca in Architettura/Progett…

Lab-scale investigation of a pressure retarded osmosis module fed by "non-conventional" salinity gradient

2015

Aim of this work has been to investigate the feasibility of PRO technology for power generation from saline streams originated by different water treatments plants, namely brine from a thermal desalination plant and fresh water from a sewage treatment plant.

CFD simulations of spacer-filled channels for pressure retarded osmosis applications

2015

Different spacer features and operating conditions were investigated in order to identify a good compromise between concentration polarization and pumping power reductions.

Recycling Phosphorus from Agricultural Streams: Grey and Green Solutions

2022

Many intensively farmed soils show high phosphorus (P) contents compared to the thresholds required for agricultural production; 0.084 Mt of P year−1 is leaving the European terrestrial system. This paper focuses mainly on non-point flows of P and provides an overview of the most promising and sustainable solutions for P recycling, centred on waste materials from agriculture. Given the global shortage of the primary resource of P, its management is critical for its efficient use. Nowadays, wastage and loss at every stage of the P cycle raise concerns about future supplies and especially about the resulting environmental problems, such as the eutrophication of surface water bodies and the re…
