La termodinamica del processo di svuotamento per evaporazione indotta da una pompa a vuoto in un serbatoio a volume costante è studiata teoricamente e sperimentalmente al fine di caratterizzare la dinamica del sistema e prevederne le condizioni critiche di funzionamento. Il modello termodinamico si basa sulla classica teoria monodimensionale per i sistemi aperti e fornisce previsioni che sono in ottimo accordo con i risultati sperimentali ottenuti da misurazioni su un impianto di prova.

The present study aims to analyse the land market trend with particular reference to the main typologies of crop in Sicily (1992-2010). More specifically, after examining the trend in agricultural land average prices, both in current and constant terms, the dynamic formulation of Shift and Share Analysis (DSSA) was carried out, in order to check the growth gap between the average prices in the Sicilian provinces and the correspondent regional ones over the period, and trying to identify its causes also on the basis of the relationship between land values and the agro-food markets dynamics in the investigated period. The analysis of average land values shows a positive trend in current terms, but a steady erosion in constant values. The application of DSSA highlights that the average land values expressed in current prices have a positive market dynamics (except for the province of Palermo), but lower than the overall regional trend, whereas Agrigento and Ragusa growth rates are higher than the regional one. On the contrary, the analysis in real terms shows a heavily erosive dynamics of provincial average prices which is more marked than the overall regional one, with the exception of Agrigento where the negative growth rate is lower than the overall trend. The analysis also measured the growth differential between the dynamics of the average values for each crop typology and the overall regional trend. More specifically, the study pointed out the dichotomy characterising the Sicilian land market in the period 1992-2010: on the one hand, the positive data of arable and horticultural crops and, to a lesser extent, permanent grassland due to a good structural framework capable of absorbing the shortcomings at local level, on the other hand, negative growth differential recorded for tree crops, due almost exclusively to substantial structural weaknesses.

Obiettivo dello studio è comprendere come l’orientamento alla sostenibilità influenzi le componenti del modello di business di un’impresa e come queste si colleghino alla creazione di valore economico, ambientale e sociale. La ricerca è stata condotta su un campione di 828 imprese appartenenti al settore vitivinicolo italiano. I risultati evidenziano che la creazione di valore sociale non influenza la dimensione economica della sostenibilità. Questa è invece la risultante di differenti approcci strategici: la sostenibilità è contemporaneamente strumento di differenziazione dell’offerta che un possibile driver di risparmio dei costi aziendali

Si riportano i risultati di una ricerca pluriennale, tutt'ora in corso, realizzata su un terreno pianeggiante del litorale toscano, riguardante la riduzione degli input colturali nella omosuccessione del mais. I trattamenti sperimentali posti a confronto sono costituiti da tre sistemi colturali caratterizzati da un diversi impiego di input meccanici e chimici: sistema convenzionale ("SC") corrispondente alla tecnica colturale ordinariamente utilizzata nel comprensorio maidicolo considerato; sistema ridotto ("SR") che prevede una decisa riduzione dei fattori produttivi sull'intera superficie di coltivazione; sistema in banda ("SB") che persegue lo stesso obiettivo della tesi precedente, attraverso però una riduzione della superficie trattata. L'analisi dei risultati conferma la superiorità produttiva del "SC" che ha determinato però il conseguimento di redditi lordi equivalenti a quelli ottenuti con il "SB" e di un'efficienza energetica inferiore a quella degli altri sistemi. I diversi andamenti meteorici registrati nel corso della sperimentazione hanno mostrato di influenzare significativamente le rese ottenute, mentre non sembra ancora individuabile, nel comportamento della coltura, un chiaro trend evolutivo legato al ripetersi dei sistemi colturali saggiati.

Lo scopo del presente lavoro è uno studio di fattibilità per la riconversione “Oxy-fuel” di una caldaia da 660 MWe alimentata a carbone, così da ottenere gas di scarico composti quasi esclusivamente da CO2 ed eliminare le problematiche della cattura post-combustione della anidride carbonica stessa. A questo scopo è stato sviluppato un modello di simulazione di una caldaia supercritica ENEL usando il software GateCycle®. Il modello è stato testato in condizioni di progetto, confrontando i risultati con i dati reali di impianto. Successivamente sono state eseguite delle simulazioni in condizioni di off-design, usando O2 puro e ricircolando i gas di scarico ricchi in CO2. In particolare sono state simulate quattro configurazioni di impianto, sia dal punto di vista delle performance che della complessità realizzativa. I risultati ottenuti sono interessanti, soprattutto per quanto riguarda le influenze quantitative dei parametri di impianto e delle configurazioni analizzate sulle performance della caldaia.

La necessità della diversificazione delle fonti energetiche, unita agli impegni sul contenimento dei consumi energetici e sulla riduzione delle emissioni di gas serra, pone la fonte solare nella condizione di avere un ruolo incisivo nel panorama energetico italiano. Tra le tecnologie disponibili per lo sfruttamento della fonte solare per la produzione di energia, il solare termodinamico (Concentrating Solar Power – CSP) consente di produrre calore ad alta temperatura mediante sistemi solari a concentrazione. Con riferimento ad un impianto da 100 kWe costituito da un campo solare di tipo Solar Trough e da un gruppo di potenza basato su ciclo Rankine a fluidi organici, il cui prototipo verrà realizzato nell’ambito del progetto SOLAR, il presente studio si prefigge di effettuare una previsione della produzione di energia elettrica e di calore. Inoltre, si analizza la possibilità di realizzare il raffrescamento estivo mediante macchine frigorifere ad assorbimento valutando il risparmio energetico associato.

Obiettivo dello studio è comprendere come l’orientamento alla sostenibilità influenzi le componenti del modello di business di un’impresa e come queste si colleghino alla creazione di valore economico, ambientale e sociale. La ricerca è stata condotta su un campione di 828 imprese appartenenti al settore vitivinicolo italiano. I risultati evidenziano che la creazione di valore sociale non influenza la dimensione economica della sostenibilità. Questa è invece la risultante di differenti approcci strategici: la sostenibilità è contemporaneamente strumento di differenziazione dell’offerta che un possibile driver di risparmio dei costi aziendali

Si riportano i risultati di una ricerca pluriennale, tutt'ora in corso, realizzata su un terreno pianeggiante del litorale toscano, riguardante la riduzione degli input colturali nella omosuccessione del mais. I trattamenti sperimentali posti a confronto sono costituiti da tre sistemi colturali caratterizzati da un diversi impiego di input meccanici e chimici: sistema convenzionale ("SC") corrispondente alla tecnica colturale ordinariamente utilizzata nel comprensorio maidicolo considerato; sistema ridotto ("SR") che prevede una decisa riduzione dei fattori produttivi sull'intera superficie di coltivazione; sistema in banda ("SB") che persegue lo stesso obiettivo della tesi precedente, attraverso però una riduzione della superficie trattata. L'analisi dei risultati conferma la superiorità produttiva del "SC" che ha determinato però il conseguimento di redditi lordi equivalenti a quelli ottenuti con il "SB" e di un'efficienza energetica inferiore a quella degli altri sistemi. I diversi andamenti meteorici registrati nel corso della sperimentazione hanno mostrato di influenzare significativamente le rese ottenute, mentre non sembra ancora individuabile, nel comportamento della coltura, un chiaro trend evolutivo legato al ripetersi dei sistemi colturali saggiati.

Lo scopo del presente lavoro è uno studio di fattibilità per la riconversione “Oxy-fuel” di una caldaia da 660 MWe alimentata a carbone, così da ottenere gas di scarico composti quasi esclusivamente da CO2 ed eliminare le problematiche della cattura post-combustione della anidride carbonica stessa. A questo scopo è stato sviluppato un modello di simulazione di una caldaia supercritica ENEL usando il software GateCycle®. Il modello è stato testato in condizioni di progetto, confrontando i risultati con i dati reali di impianto. Successivamente sono state eseguite delle simulazioni in condizioni di off-design, usando O2 puro e ricircolando i gas di scarico ricchi in CO2. In particolare sono state simulate quattro configurazioni di impianto, sia dal punto di vista delle performance che della complessità realizzativa. I risultati ottenuti sono interessanti, soprattutto per quanto riguarda le influenze quantitative dei parametri di impianto e delle configurazioni analizzate sulle performance della caldaia.

La necessità della diversificazione delle fonti energetiche, unita agli impegni sul contenimento dei consumi energetici e sulla riduzione delle emissioni di gas serra, pone la fonte solare nella condizione di avere un ruolo incisivo nel panorama energetico italiano. Tra le tecnologie disponibili per lo sfruttamento della fonte solare per la produzione di energia, il solare termodinamico (Concentrating Solar Power – CSP) consente di produrre calore ad alta temperatura mediante sistemi solari a concentrazione. Con riferimento ad un impianto da 100 kWe costituito da un campo solare di tipo Solar Trough e da un gruppo di potenza basato su ciclo Rankine a fluidi organici, il cui prototipo verrà realizzato nell’ambito del progetto SOLAR, il presente studio si prefigge di effettuare una previsione della produzione di energia elettrica e di calore. Inoltre, si analizza la possibilità di realizzare il raffrescamento estivo mediante macchine frigorifere ad assorbimento valutando il risparmio energetico associato.
