description Publicationkeyboard_double_arrow_right Doctoral thesis ItalyAuthors: MILANA, GIULIANO;The study of the dietary changes which have intervened over the years in generalist and opportunist predators may provide useful information on the temporal modifications of their prey communities, especially under a climate change scenario. In this study, we analyzed the quantitative changes in the small mammals portion of the diet of two generalist and opportunist predators, the Barn owl (Tyto alba) and the Asp viper (Vipera aspis), in a forest zone in central Italy, for the period respectively 1987-2010 and 1975-2008. Concerning the Barn Owl, studied through the analysis of its pellets, there was no apparent change over the years, except for an increasing trend of syn-anthropic species Mus musculus domesticus and Rattus rattus. Similarly Microtus savii, a typical rodent of agroteriocoenoses, doesn’t show significant variations over the years. However, since I did not obtain a longitudinal long-term dataset on Barn owl pellets, I tested the methodology through a longitudinal sampling (for 30 years) at two Spanish areas. In this case it was possible to record a significant increase in two termoxerofilic species, Mus spretus and Crocidura russula, during the period analyzed. However, correlating this increase with thermopluviometric data for the same Iberian areas there wasn’t a significant correlation. As regards the analysis of the diet of the Viper, this issue was also studied through the analysis of ingesta, for a longitudinal period of 20 years. Among the various taxa eaten by vipers, only two showed significantly consistent trends over the years, with Myodes glareolus increasing and Sorex spp. declining in the viper diet. Despite being temperate-zone forest-associated species, hence likely adversed by global warming, Sorex spp. and Myodes glareolus showed opposite trends over the years, thus suggesting that such trends may reflect more local scale perturbations (local forest overgrowth and diminution of logging). I also found a significantly positive relationship between small mammals abundance in the field and their relative frequency of occurrence in the viper’s diet, thus demonstrating that vipers really sampled the small mammal species in relation to their local availability. However, global warming has certainly had an effect on the activity rhythms of predators: for example, some aspects of the annual phenology of the same populations of Viper studied for the diet have changed over the years according to patterns related to the global warming. This work therefore show the effectiveness of some indirect sampling methods in the study of temporal variations in small mammals highlighting some relevant limitations. We also tried to investigate the human impact through mutagenetic tests (micronucleus test on peripheral blood) and investigations in relation to bioaccumulation of trace elements in wild rodents. For this kind of analysis we made three different trapping sessions of small mammals in two areas: Canale Monterano and Civitavecchia. These areas are characterized by different conditions of anthropic impact: - about Civitavecchia (Santagostino) we are in a mostly urbanized and man-made environment in relation with the presence of the largest european energy hub consisting of the Torvaldaliga power plants. - about Canale Monterano there is a situation of greater naturalness, with agricultural areas, pastures and forest patches. With regard to the accumulation of trace elements analysis were conducted on the hair of small mammals captured and on the bones from barn owl’s pellets. The results show some significant differences for the two locations examined, in particular for the site of Canale Monterano readings are significantly higher in bone samples for the following elements Tl, Th and U due to the geology of the area, while, on the hair is confirmed a difference to Tl as well as a higher concentration of Pb in samples of Civitavecchia. This result is very interesting because it is directly attributable to the higher vehicular traffic and industrial pollution of Civitavecchia. The other important data concerne the concentrations of Mn, which could be due to use of fungicides in agriculture. With regard to micronucleus test, on erythrocytes from circulating blood, analysis showed a generalized genetic damage (from 0 to 8 MN in 1000 MNE) for both locations, according to the Mackey & MacGregor (1979) index used as reference (MNE/1000 ≥ 2), suggesting an alteration of the overall environmental situation

Moreover, most of the actual stock is characterized by low energy performances since it pre-dates the energy regulation. The paper aims at addressing this issue by proposing the integration of Building Simulation (BS) approach, Multi-Criteria Analysis (MCA) methods and Geographic Information System (GIS) tool for developing a new Multi-Criteria Spatial Decision Support System (MC-SDSS) in urban context. The BS of relevant building archetypes allows to identify different resolutions of energy data: hour-by-hour data can be useful for demand-side management or renewable integration while aggregated data can be used for load forecasting and retrofit simulations. The MCA permits choosing between different building renovation alternatives by considering both qualitative and quantitative criteria. Moreover, the GIS support the method by creating geo-referenced databases. The method purposes in giving a comprehensive view to address the complexity of urban building energy planning; due to its flexibility, it can be applied to several urban areas. Three main phases characterize the study: i. overview of relevant existing techniques; ii. description of the integrated proposed method; iii. discussion and future application. The method can provide relevant feedbacks for ranking complex design energy options.

Journal of Land Use, Mobility and Environment Authors: Fistola, Romano;Prefigurare assetti urbani futuri nei quali le tecnologie consentano azioni e interazioni fra gli individui inimmaginabili solo pochi anni fa, ha da sempre rappresentato una delle tematiche di ricerca ed approfondimento più interessanti delle scienze della città anche se, probabilmente, non sufficientemente considerate nel dibattito urbanistico del nostro paese degli ultimi venti anni. L’accelerazione verso tali tematiche è stata consistente a partire dai recenti bandi della Comunità Europea e del Ministero dell’Istruzione e della Ricerca Italiano sulle: Smart City. In questa importante svolta, supportata dalle numerose aziende produttrici di tecnologie, dispositivi e media, sembra tuttavia verificarsi una discontinuità nell’ambito della definizione teorica dei processi connessi alla strutturazione ed alla gestione della Smart City. I numerosi approfondimenti sul tema sembrano svilupparsi lontano dalle scienze del governo delle trasformazioni della città e distanti dal principale ambito disciplinare di riferimento: l’urbanistica. Tale discrasia è probabilmente riconducibile a due fattori: da una parte la marginalizzazione del tema relativo a città ed innovazione tecnologica nel dibattito urbanistico nazionale concentratosi su altri, pur importanti, argomenti e, dall’altra l’approccio marcatamente aziendale che la recente accelerazione ha subito e che, in una logica di mercato, tende ad evitare possibili razionalizzazioni dei processi. All’interno del testo verranno proposti approcci, ipotesi e riflessioni probabilmente non strutturate per definire un ordinato sviluppo teorico ma, probabilmente in grado di aprire dimensioni del ragionamento ed indicare possibili scenari che possano essere successivamente ripresi, confutati e riarticolati dagli altri studiosi delle scienze urbane per definirne un nuovo modo di interpretare e tentare di orientare lo sviluppo urbano. Molte delle riflessioni presentate nel seguito rappresentano semplici spunti che necessitano di ulteriori approfondimenti e sviluppi maggiormente strutturati. Ma pare utile avviare un ragionamento che dimostri come la proposizione del modello “smart” per i moderni sistemi urbani non derivi unicamente da necessità tecnicisticamente aziendali, che spingono all’utilizzo di device di controllo urbano, ma possano essere visti come uno stadio evolutivo della città del quale già da tempo si erano prefigurati gli sviluppi. In altre parole obiettivo di questo paper è quello di tentare di ricondurre le dinamiche di sviluppo della SC nel loro naturale alveo di sviluppo teorico-operativo, anche recuperando approcci e riferimenti metodologici riconducibili allo studio del rapporto fra nuove tecnologie e trasformazioni del sistema urbano da tempo sviluppati in sede di ricerca ma mai concretamente adottati per la definizione di nuovi processi di governo della città.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Report 2021 ItalyAuthors: Erika D'Aleo; Monica Musolino;La transizione energetica e lo sviluppo sempre più capillare delle energie da fonti rinnovabili stanno suscitando un interesse sempre più crescente, favorendo la nascita di comunità per la produzione di energia e l'autoconsumo collettivo, al fine di ridurre drasticamente le emissioni e poter così raggiungere definitivamente l'obiettivo di decarbonizzazione prefissato per il 2050 dall'Unione Europea. Nel nostro Paese, le comunità energetiche potranno diventare il volano per le energie da fonti rinnovabili, permettendo ai cittadini di partecipare alla generazione, alla distribuzione, alla fornitura, al consumo, all'aggregazione ed allo stoccaggio dell'energia. Proprio attraverso una maggiore consapevolezza del fenomeno che si sta sviluppando, i cittadini possono associarsi ed effettuare scelte comuni per produrre localmente l'energia elettrica necessaria al proprio fabbisogno, anche condividendola, avendo così accesso a servizi di efficienza energetica. Queste nuove forme di mobilitazione collettiva, già note nei movimenti comunitari legati alla filiera alimentare, cominciano a diventare sempre più presenti nella costituzione delle comunità energetiche, con il fine ultimo, non solo di ridurre l'uso di fonti fossili ed emissioni, in favore di un sistema energetico basato sull'impiego di risorse energetiche rinnovabili, ma anche di poter produrre innovazione sociale in termini di empowerment delle persone, inclusività ed impatto di lunga durata, incoraggiando il cambiamento di pratiche sociali e valori collettivi; il mutamento tecnologico, quanto quello sociale, può essere soddisfatto solo da un forte coinvolgimento degli attori sociali.

Di fronte alle ipotesi d’intervento politico-strategico scaturite dalle «Dichiarazioni» di Lisbona (2000, 2003 e 2005) e Gothenburg (2001), sono emersi orientamenti, approcci, proposte e iniziative diversi, a volte contrastanti. I risultati del progetto di ricerca transnazionale promosso dall’European Spatial Program Observatory Network (ESPON) dal titolo La dimensione territoriale della strategia Lisbona/Gothenburg ha lo scopo di individuare politiche e criteri comuni secondo cui sviluppare simultaneamente, entro il 2010, in tutti i paesi e le regioni dell’Unione Europea un’economia basata su una conoscenza competitiva (Lisbona) e allo stesso tempo sostenibile (Gothenburg).Dedicare un intero numero del Bollettino della Società Geografica Italiana al tema della «competitività territoriale», ai suoi diversi aspetti, a come si può e si deve misurare, non è solo una scelta dettata dall’attualità di un tema, che comunque chiede una sollecita risposta anche dall’ambito in cui si muove la ricerca geografica e non solo dall’economia. E’ piuttosto la volontà di “partecipare” una precisa linea metodologica ed i risultati che si sono ottenuti in questi ultimi anni rispondendo ai numerosi inviti al cambiamento ed all’innovazione strutturale che vengono dall’Unione Europea, di cui Filippo Bencardino e Maria Prezioso si sono fatti carico impegnandosi nella cura di questo numero. La Dichiarazione di Lisbona (2000) prima, quella di Gothenburg (2001) poi, l’allargamento a 25 (2004) hanno evidenziato la necessità di predisporre modelli politico-organizzativi utili all’integrazione cooperativa tra Stati e regioni, spesso troppo piccoli per esercitare nuove funzioni di politica industriale e monetaria; nell’ambito della competizione tra poli nazionali e sovranazionali (primo fra tutti l’Unione stessa), troppo diversi per garantire il controllo del governo locale dell’economia e del territorio. L’Unione ha posto in luce una più netta e distintiva differenza al suo interno, partendo dalla constatazione che anche le regioni, oltre ...

Phytoparasitic nematodes cause heavy annual yield losses and thus can be considered among the most dangerous pests for a number of vegetable crops. Management of these parasites has been traditionally based on synthetic pesticides, but because of their high environmental impact we need to find more sustainable products to control nematodes. Biocidal compounds, naturally occurring as products of plant secondary metabolism, may represent a large source of biocompatible nematicides. This review briefly reports the main botanical groups and plant secondary metabolites with a nematicidal potential, as well as the most effective techniques for their exploitation. Nematotoxic volatile products, such as isothiocyanates and nitriles released from the degradation of glucosinolates present in tissues of Brassicaceae plants or cyanide deriving from the cyanogenic glucosides of some Sorghum species can be exploited for nematode control through the incorporation of fresh or dry plant material into the soil. Commercial liquid formulations based on seed oils from neem (Azadirachta indica Juss.) or sesame (Sesamum indicum L.) or water extracts from quillay (Quillaja saponaria Molina) bark or tagetes (Tagetes erecta L.) are already available for soil treatments over the crop cycle and/or seedling root dipping before t ransplant . Many plant species from Asteraceae family, such as Calendula spp., Chrysanthemum spp. and Artemisia spp., have been also demonstrated to be a potential source of nematicidal products for the control of root-knot and cyst phytonematodes economically relevant to vegetable crops. Green manures or crop rotations with indigenous (Medicago spp., Trifolium spp., Vicia spp., Lupinus albus) and tropical (Mucuna spp., Crotalaria spp) Leguminosae species, as well as soil amendments with their formulated plant biomass, have been reported to achieve a satisfactory nematode suppression, due to the high content of bioactive metabolites (phenols, alkaloids, alcohols and mainly saponins) of these plants. Essential oils ...

A tal proposito è stato studiato l’impiego di un reattore prototipale a letto fisso di tipo Imbert per la gassificazione del biotriturato, ottenuto a seguito dell’essiccamento e successiva triturazione delle potature di nocciolo. I risultati ottenuti mostrano la capacità del sistema di gassificazione di produrre un syngas avente caratteristiche in linea con i dati di letteratura. Dalla sperimentazione condotta si evince che le percentuali in volume di monossido di carbonio ed idrogeno variano rispettivamente dal 14% al 17% e dal 13% a poco meno del 17% mentre il contenuto di metano si è mantenuto mediamente al di sotto del 2%. Il potere calorifico inferiore del syngas è risultato oscillare in un intervallo tra i 3,85 MJ/Nm3 e i 4,46 MJ/Nm3. ; In the present work the energy recovery of residual biomass from hazelnut pruning has been studied, in order to enhance the local resources according to the strong local hazelnut production. As a consequence, the use of a fixed bed Imbert prototype reactor for the gasification of biomass, obtained after drying and subsequent shredding of hazelnut pruning, has been investigated. The results are in good agreement with literature data in terms of syngas energy properties. In more detail, experiments have shown that the percentage by volume of carbon monoxide and hydrogen varies from 14% to 17% and from 13% to a value slightly lower than 17%, respectively, while the average methane content is less than 2% by volume. The lower heating value of syngas ranges from 3,85 MJ/Nm3 to 4,46 MJ/Nm3.

We propose a wide land planning tool including a section devoted to the calculation of the energy that can be produced by plants located in the permitted areas, an evaluative section devoted to the financial sustainability of the investments, and a section devoted to the landscape assessment due to the different intervisibility of the allowed plants, and a section devoted to the formalization of the decision making process. A set of GIS tools supports the mentioned sections in defining the pattern for the localization of the wind farms, and in measuring and featuring the visual impact.

description Publicationkeyboard_double_arrow_right Doctoral thesis ItalyAuthors: MILANA, GIULIANO;The study of the dietary changes which have intervened over the years in generalist and opportunist predators may provide useful information on the temporal modifications of their prey communities, especially under a climate change scenario. In this study, we analyzed the quantitative changes in the small mammals portion of the diet of two generalist and opportunist predators, the Barn owl (Tyto alba) and the Asp viper (Vipera aspis), in a forest zone in central Italy, for the period respectively 1987-2010 and 1975-2008. Concerning the Barn Owl, studied through the analysis of its pellets, there was no apparent change over the years, except for an increasing trend of syn-anthropic species Mus musculus domesticus and Rattus rattus. Similarly Microtus savii, a typical rodent of agroteriocoenoses, doesn’t show significant variations over the years. However, since I did not obtain a longitudinal long-term dataset on Barn owl pellets, I tested the methodology through a longitudinal sampling (for 30 years) at two Spanish areas. In this case it was possible to record a significant increase in two termoxerofilic species, Mus spretus and Crocidura russula, during the period analyzed. However, correlating this increase with thermopluviometric data for the same Iberian areas there wasn’t a significant correlation. As regards the analysis of the diet of the Viper, this issue was also studied through the analysis of ingesta, for a longitudinal period of 20 years. Among the various taxa eaten by vipers, only two showed significantly consistent trends over the years, with Myodes glareolus increasing and Sorex spp. declining in the viper diet. Despite being temperate-zone forest-associated species, hence likely adversed by global warming, Sorex spp. and Myodes glareolus showed opposite trends over the years, thus suggesting that such trends may reflect more local scale perturbations (local forest overgrowth and diminution of logging). I also found a significantly positive relationship between small mammals abundance in the field and their relative frequency of occurrence in the viper’s diet, thus demonstrating that vipers really sampled the small mammal species in relation to their local availability. However, global warming has certainly had an effect on the activity rhythms of predators: for example, some aspects of the annual phenology of the same populations of Viper studied for the diet have changed over the years according to patterns related to the global warming. This work therefore show the effectiveness of some indirect sampling methods in the study of temporal variations in small mammals highlighting some relevant limitations. We also tried to investigate the human impact through mutagenetic tests (micronucleus test on peripheral blood) and investigations in relation to bioaccumulation of trace elements in wild rodents. For this kind of analysis we made three different trapping sessions of small mammals in two areas: Canale Monterano and Civitavecchia. These areas are characterized by different conditions of anthropic impact: - about Civitavecchia (Santagostino) we are in a mostly urbanized and man-made environment in relation with the presence of the largest european energy hub consisting of the Torvaldaliga power plants. - about Canale Monterano there is a situation of greater naturalness, with agricultural areas, pastures and forest patches. With regard to the accumulation of trace elements analysis were conducted on the hair of small mammals captured and on the bones from barn owl’s pellets. The results show some significant differences for the two locations examined, in particular for the site of Canale Monterano readings are significantly higher in bone samples for the following elements Tl, Th and U due to the geology of the area, while, on the hair is confirmed a difference to Tl as well as a higher concentration of Pb in samples of Civitavecchia. This result is very interesting because it is directly attributable to the higher vehicular traffic and industrial pollution of Civitavecchia. The other important data concerne the concentrations of Mn, which could be due to use of fungicides in agriculture. With regard to micronucleus test, on erythrocytes from circulating blood, analysis showed a generalized genetic damage (from 0 to 8 MN in 1000 MNE) for both locations, according to the Mackey & MacGregor (1979) index used as reference (MNE/1000 ≥ 2), suggesting an alteration of the overall environmental situation

Moreover, most of the actual stock is characterized by low energy performances since it pre-dates the energy regulation. The paper aims at addressing this issue by proposing the integration of Building Simulation (BS) approach, Multi-Criteria Analysis (MCA) methods and Geographic Information System (GIS) tool for developing a new Multi-Criteria Spatial Decision Support System (MC-SDSS) in urban context. The BS of relevant building archetypes allows to identify different resolutions of energy data: hour-by-hour data can be useful for demand-side management or renewable integration while aggregated data can be used for load forecasting and retrofit simulations. The MCA permits choosing between different building renovation alternatives by considering both qualitative and quantitative criteria. Moreover, the GIS support the method by creating geo-referenced databases. The method purposes in giving a comprehensive view to address the complexity of urban building energy planning; due to its flexibility, it can be applied to several urban areas. Three main phases characterize the study: i. overview of relevant existing techniques; ii. description of the integrated proposed method; iii. discussion and future application. The method can provide relevant feedbacks for ranking complex design energy options.

Journal of Land Use, Mobility and Environment Authors: Fistola, Romano;Prefigurare assetti urbani futuri nei quali le tecnologie consentano azioni e interazioni fra gli individui inimmaginabili solo pochi anni fa, ha da sempre rappresentato una delle tematiche di ricerca ed approfondimento più interessanti delle scienze della città anche se, probabilmente, non sufficientemente considerate nel dibattito urbanistico del nostro paese degli ultimi venti anni. L’accelerazione verso tali tematiche è stata consistente a partire dai recenti bandi della Comunità Europea e del Ministero dell’Istruzione e della Ricerca Italiano sulle: Smart City. In questa importante svolta, supportata dalle numerose aziende produttrici di tecnologie, dispositivi e media, sembra tuttavia verificarsi una discontinuità nell’ambito della definizione teorica dei processi connessi alla strutturazione ed alla gestione della Smart City. I numerosi approfondimenti sul tema sembrano svilupparsi lontano dalle scienze del governo delle trasformazioni della città e distanti dal principale ambito disciplinare di riferimento: l’urbanistica. Tale discrasia è probabilmente riconducibile a due fattori: da una parte la marginalizzazione del tema relativo a città ed innovazione tecnologica nel dibattito urbanistico nazionale concentratosi su altri, pur importanti, argomenti e, dall’altra l’approccio marcatamente aziendale che la recente accelerazione ha subito e che, in una logica di mercato, tende ad evitare possibili razionalizzazioni dei processi. All’interno del testo verranno proposti approcci, ipotesi e riflessioni probabilmente non strutturate per definire un ordinato sviluppo teorico ma, probabilmente in grado di aprire dimensioni del ragionamento ed indicare possibili scenari che possano essere successivamente ripresi, confutati e riarticolati dagli altri studiosi delle scienze urbane per definirne un nuovo modo di interpretare e tentare di orientare lo sviluppo urbano. Molte delle riflessioni presentate nel seguito rappresentano semplici spunti che necessitano di ulteriori approfondimenti e sviluppi maggiormente strutturati. Ma pare utile avviare un ragionamento che dimostri come la proposizione del modello “smart” per i moderni sistemi urbani non derivi unicamente da necessità tecnicisticamente aziendali, che spingono all’utilizzo di device di controllo urbano, ma possano essere visti come uno stadio evolutivo della città del quale già da tempo si erano prefigurati gli sviluppi. In altre parole obiettivo di questo paper è quello di tentare di ricondurre le dinamiche di sviluppo della SC nel loro naturale alveo di sviluppo teorico-operativo, anche recuperando approcci e riferimenti metodologici riconducibili allo studio del rapporto fra nuove tecnologie e trasformazioni del sistema urbano da tempo sviluppati in sede di ricerca ma mai concretamente adottati per la definizione di nuovi processi di governo della città.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Report 2021 ItalyAuthors: Erika D'Aleo; Monica Musolino;La transizione energetica e lo sviluppo sempre più capillare delle energie da fonti rinnovabili stanno suscitando un interesse sempre più crescente, favorendo la nascita di comunità per la produzione di energia e l'autoconsumo collettivo, al fine di ridurre drasticamente le emissioni e poter così raggiungere definitivamente l'obiettivo di decarbonizzazione prefissato per il 2050 dall'Unione Europea. Nel nostro Paese, le comunità energetiche potranno diventare il volano per le energie da fonti rinnovabili, permettendo ai cittadini di partecipare alla generazione, alla distribuzione, alla fornitura, al consumo, all'aggregazione ed allo stoccaggio dell'energia. Proprio attraverso una maggiore consapevolezza del fenomeno che si sta sviluppando, i cittadini possono associarsi ed effettuare scelte comuni per produrre localmente l'energia elettrica necessaria al proprio fabbisogno, anche condividendola, avendo così accesso a servizi di efficienza energetica. Queste nuove forme di mobilitazione collettiva, già note nei movimenti comunitari legati alla filiera alimentare, cominciano a diventare sempre più presenti nella costituzione delle comunità energetiche, con il fine ultimo, non solo di ridurre l'uso di fonti fossili ed emissioni, in favore di un sistema energetico basato sull'impiego di risorse energetiche rinnovabili, ma anche di poter produrre innovazione sociale in termini di empowerment delle persone, inclusività ed impatto di lunga durata, incoraggiando il cambiamento di pratiche sociali e valori collettivi; il mutamento tecnologico, quanto quello sociale, può essere soddisfatto solo da un forte coinvolgimento degli attori sociali.

Di fronte alle ipotesi d’intervento politico-strategico scaturite dalle «Dichiarazioni» di Lisbona (2000, 2003 e 2005) e Gothenburg (2001), sono emersi orientamenti, approcci, proposte e iniziative diversi, a volte contrastanti. I risultati del progetto di ricerca transnazionale promosso dall’European Spatial Program Observatory Network (ESPON) dal titolo La dimensione territoriale della strategia Lisbona/Gothenburg ha lo scopo di individuare politiche e criteri comuni secondo cui sviluppare simultaneamente, entro il 2010, in tutti i paesi e le regioni dell’Unione Europea un’economia basata su una conoscenza competitiva (Lisbona) e allo stesso tempo sostenibile (Gothenburg).Dedicare un intero numero del Bollettino della Società Geografica Italiana al tema della «competitività territoriale», ai suoi diversi aspetti, a come si può e si deve misurare, non è solo una scelta dettata dall’attualità di un tema, che comunque chiede una sollecita risposta anche dall’ambito in cui si muove la ricerca geografica e non solo dall’economia. E’ piuttosto la volontà di “partecipare” una precisa linea metodologica ed i risultati che si sono ottenuti in questi ultimi anni rispondendo ai numerosi inviti al cambiamento ed all’innovazione strutturale che vengono dall’Unione Europea, di cui Filippo Bencardino e Maria Prezioso si sono fatti carico impegnandosi nella cura di questo numero. La Dichiarazione di Lisbona (2000) prima, quella di Gothenburg (2001) poi, l’allargamento a 25 (2004) hanno evidenziato la necessità di predisporre modelli politico-organizzativi utili all’integrazione cooperativa tra Stati e regioni, spesso troppo piccoli per esercitare nuove funzioni di politica industriale e monetaria; nell’ambito della competizione tra poli nazionali e sovranazionali (primo fra tutti l’Unione stessa), troppo diversi per garantire il controllo del governo locale dell’economia e del territorio. L’Unione ha posto in luce una più netta e distintiva differenza al suo interno, partendo dalla constatazione che anche le regioni, oltre ...

Phytoparasitic nematodes cause heavy annual yield losses and thus can be considered among the most dangerous pests for a number of vegetable crops. Management of these parasites has been traditionally based on synthetic pesticides, but because of their high environmental impact we need to find more sustainable products to control nematodes. Biocidal compounds, naturally occurring as products of plant secondary metabolism, may represent a large source of biocompatible nematicides. This review briefly reports the main botanical groups and plant secondary metabolites with a nematicidal potential, as well as the most effective techniques for their exploitation. Nematotoxic volatile products, such as isothiocyanates and nitriles released from the degradation of glucosinolates present in tissues of Brassicaceae plants or cyanide deriving from the cyanogenic glucosides of some Sorghum species can be exploited for nematode control through the incorporation of fresh or dry plant material into the soil. Commercial liquid formulations based on seed oils from neem (Azadirachta indica Juss.) or sesame (Sesamum indicum L.) or water extracts from quillay (Quillaja saponaria Molina) bark or tagetes (Tagetes erecta L.) are already available for soil treatments over the crop cycle and/or seedling root dipping before t ransplant . Many plant species from Asteraceae family, such as Calendula spp., Chrysanthemum spp. and Artemisia spp., have been also demonstrated to be a potential source of nematicidal products for the control of root-knot and cyst phytonematodes economically relevant to vegetable crops. Green manures or crop rotations with indigenous (Medicago spp., Trifolium spp., Vicia spp., Lupinus albus) and tropical (Mucuna spp., Crotalaria spp) Leguminosae species, as well as soil amendments with their formulated plant biomass, have been reported to achieve a satisfactory nematode suppression, due to the high content of bioactive metabolites (phenols, alkaloids, alcohols and mainly saponins) of these plants. Essential oils ...

A tal proposito è stato studiato l’impiego di un reattore prototipale a letto fisso di tipo Imbert per la gassificazione del biotriturato, ottenuto a seguito dell’essiccamento e successiva triturazione delle potature di nocciolo. I risultati ottenuti mostrano la capacità del sistema di gassificazione di produrre un syngas avente caratteristiche in linea con i dati di letteratura. Dalla sperimentazione condotta si evince che le percentuali in volume di monossido di carbonio ed idrogeno variano rispettivamente dal 14% al 17% e dal 13% a poco meno del 17% mentre il contenuto di metano si è mantenuto mediamente al di sotto del 2%. Il potere calorifico inferiore del syngas è risultato oscillare in un intervallo tra i 3,85 MJ/Nm3 e i 4,46 MJ/Nm3. ; In the present work the energy recovery of residual biomass from hazelnut pruning has been studied, in order to enhance the local resources according to the strong local hazelnut production. As a consequence, the use of a fixed bed Imbert prototype reactor for the gasification of biomass, obtained after drying and subsequent shredding of hazelnut pruning, has been investigated. The results are in good agreement with literature data in terms of syngas energy properties. In more detail, experiments have shown that the percentage by volume of carbon monoxide and hydrogen varies from 14% to 17% and from 13% to a value slightly lower than 17%, respectively, while the average methane content is less than 2% by volume. The lower heating value of syngas ranges from 3,85 MJ/Nm3 to 4,46 MJ/Nm3.

The study highlighted some remarkable differences between the two provinces due to the different wind dynamics and the presence of the landscape characteristics. We propose a wide land planning tool including a section devoted to the calculation of the energy that can be produced by plants located in the permitted areas, an evaluative section devoted to the financial sustainability of the investments, and a section devoted to the landscape assessment due to the different intervisibility of the allowed plants, and a section devoted to the formalization of the decision making process. A set of GIS tools supports the mentioned sections in defining the pattern for the localization of the wind farms, and in measuring and featuring the visual impact.
