Use of a temperature-measuring chain for the reconstruction of the vertical thermal disturbance induced by an open-loop groundwater heat pump system
Get PDFOpen-loop groundwater heat pumps (GWHP) currently represent one of the most energy-efficient and environmentally friendly air-conditioning systems for densely urbanised areas. Depending on the use mode, energy can be extracted or injected into a shallow aquifer. Among the technical aspects associated with GWHPs that need to be constantly controlled, there is the development of a thermally affected zone (TAZ) around injection points. The environmental impact extent is strongly influenced by the water flow rates and the re-injection modalities. The process of setting up an adequate monitoring system is fundamental for the proper reconstruction of TAZ propagation modes, during each plant-operating season. The work aims to analyse the potentialities of using a new sophisticated water temperature-measuring chain (type PT1004/Pt) as a monitoring tool for the identification of the vertical stratigraphic intervals of the Turin shallow aquifer that are more affected by the thermal disturbances produced by the Politecnico di Torino’s open-loop GWHP system. The installation of such a monitoring instrument, together with the information deriving from the application of the data analysis proposed, can contribute the most in understanding the adequacy of the constructional characteristics of an open-loop system re-injection well to properly disperse vertical thermal perturbations
The egg endoparasitoids of Macrolenes dentipes (Olivier) (Coleoptera: Chrysomelidae), with description of a new species of Aprostocetus Westwood and notes on its host (Hymenoptera: Eulophidae)
Get PDFA new species of Aprostocetus (Chrysotetrastichus) (Hymenoptera: Eulophidae), A. macrolenei Viggiani sp. nov., has been obtained from the eggs of Macrolenes dentipes (Coleoptera: Chrysomelidae: Clytrinae) and described. It is confirmed that Bloodiella andalusica Nowicki is also an egg parasitoid of the mentioned host. Biological notes on both parasitoids are given. Phenological data on the chrysomelid host and diagnostic characters of its undescribed first-instar larva are provided
The effect of retirement on the time use of retirees
No full textIn this paper we estimate the effect of retirement on the time use of individuals. Retirement makes available a large amount of time that was previously devoted to work. In particular, this will affect the time devoted to leisure, housework, eating and sleeping. The statistical framework adopted in this study is regression in discontinuity. We use the jump in the probability of retirement at age sixty, the minimum legal retirement age in France, to measure the impact of retirement on the time use of retirees. Retirement means more time spent on household chores, sleep, leisure and meals. The magnitude of the effects may vary between men and women. The amount of time devoted to domestic tasks increases more for retired men than for retired women. However, this increase is not sufficient to close the gender gap in unpaid work
Streghe e stregoneria nella medievistica italiana degli ultimi decenni
Get PDFIl contributo ripercorre gli studi che la medievistica degli ultimi cinquant’anni ha prodotto sul fenomeno stregonico, analizzando la progressiva accentuazione del carattere transdisciplinare della tematica e la conseguente contestualizzazione delle pratiche di stregoneria all’interno di una riflessione di più ampia portata. L’edizione di fonti sinora non pubblicate e le riletture di testimonianze note hanno messo in luce le molte imprecisioni che, nel passato, hanno contraddistinto le convinzioni sulla stregoneria. L’articolo propone alcuni particolari casi di studio a supporto delle considerazioni interpretative e allo scopo di dimostrare quanto fosse labile il confine tra la sete di conoscenza, soprattutto se proveniente dalgenere femminile, e l’accusa di stregoneria
Lobbying for Design Protection: a Perspective on France and the United States During the First Half of the Twentieth Century
Get PDFIl saggio presenta una ricerca sull’ascesa delle professioni legali nel settore della moda. Dalla fine del XIX secolo, gli imprenditori creativi nel settore della moda hanno sviluppato un vivo interesse nell’utilizzo degli strumenti legali per proteggere i loro diritti di proprietà intellettuale, siano essi brevetti, marchi, diritti d’autore o segreti commerciali. In tal modo, gli imprenditori della moda, in particolare le Sorelle Callot, Paul Poiret, Madeleine Vionnet, Maurice Rentner e Christian Dior, hanno lavorato con avvocati che hanno difeso i loro interessi nei tribunali e che hanno contribuito a costruire un crescente corpus giurisprudenziale relativo all’industria della moda. Basato su archivi di Tribunali e di aziende e su fonti di stampa, lo studio esamina i profili degli avvocati che hanno aperto la strada a quella che è diventata oggi legge sulla moda, nel contesto di due grandi paesi produttori di abbigliamento: Francia e Stati Uniti. Gli imprenditori della moda hanno assunto avvocati per casi occasionali, ma anche consulenti legali interni. L’articolo, quindi, mette in luce anche il ruolo della competenza legale all’interno della direzione dell’azienda di moda, oltre ad esaminare una serie di casi giudiziari in Francia nel periodo tra le due guerre, e negli Stati Uniti nel dopoguerra, per mostrare come gli avvocati abbiano influenzato l’industria della moda
Una mater litigans nella Roma chigiana: Giovanna Cesi in Borromeo (1598-1672) e il “misconoscimento” del potere femminile nella corte pontificia di metà Seicento
Get PDFL’articolo ricostruisce il percorso di una mater litigans, cioè un’esponente della nobiltà romana che spacciò per amore materno il notevole lavoro di brokerage che svolgeva per conto del figlio prelato. Partendo dalle ricerche di Caroline Castiglione, cui dobbiamo l’espressione, l’articolo indaga le origini e le cause di questa dissimulazione. Utilizzando fonti finora sconosciute su una esemplare mater litigans, Giovanna Cesi in Borromeo (1598-1672), si dimostrerà che la retorica dell’amore materno affiorò a Roma nel momento esatto in cui il nepotismo papale entrò in crisi e dovette essere conciliato con nuovi ideali di servizi pubblico. Nel contesto più ampio della lenta transizione verso l’abolizione del nepotismo, la retorica incentrata sull’amore materno facilitò ciò che con Pierre Bourdieu chiameremo “misconoscimento”: la negazione del persistere delle reti di potere femminili da parte di una élite cortigiana che si stava convertendo ai valori del buon governo in nome del bene comune
Saline intrusion: a potential risk for coastal aquifer management in sea level rise scenarios the case study of an adaptation plan for the municipality of Fano
Get PDFThe work reported in this paper is part of a European Union project called ASTERIS and co-funded by the Interreg Italy-Croatia Cross-Border Cooperation Programme. The paper summarises the expected environmental changes resulting from North Adriatic sea level rise due to climate change, and the findings of a risk analysis of saltwater intrusion in coastal aquifers, at both regional and local scale. Starting from this scenario, and through a review of best practices, we set up an adaption plan with a view to mitigating the environmental and socio-economic damage due to the expected increase in salinisation along the coastal aquifers in the municipality of Fano (Pesaro province, Marche region, Italy). The municipal adaptation plan identifies the actions to be taken for sustainable use of groundwater, i.e. maintaining freshwater baseflow towards the sea, relocating the pumping systems to lower the interface zone, and creating barriers to saltwater ingression. The suggested adaptation measures were spatially distributed on the basis of the hydrogeological effects expected in the different zones of the coastal aquifer. These measures involve different groups of stakeholders playing key roles in the use of groundwater resources: owners of domestic wells, industrial and commercial water users depending on groundwater resources, managers of integrated water systems, urban planners, farmers, and tourist operators. Particular emphasis was placed on surface water bodies inside the town, which are in direct connection with seawater and exposed to salt wedge seepage during summers. Monitoring transects and threshold values were established in selected test sites. With regard to the progression of the saltwater intrusion process in future decades, “dynamic updating” of the adaptation plan, supported by field observations, appeared to be the most suitable method
Comparative analysis of the population structure of Crematogaster subdentata and Lasius neglectus in the primary and secondary ranges (Hymenoptera: Formicidae)
Get PDFThe population structure of Crematogaster subdentata Mayr, 1877 in the primary (native) (Uzbekistan) and secondary ranges (Crimea, Rostov-on-Don) is analyzed. The data obtained indicate an uncommon behavior for invasive ants – the formation of supercolonies in the primary range (the size of the foraging area is about 600 m2) in the urban territory. Nesting in houses and in trunks of old trees occurs both in the zone of invasion and in the primary range. The data of the distribution of the second invasive species in the same regions – Lasius neglectus Van Loon et al., 1990 are provided. Comparison of the population structure (ratio of the mono- and polycalic colonies, presence of the supercolonies and their sizes), parameters of the colonies (average number of the nests and forage trees per colony) showed the ad- vantage of Crematogaster subdentata over Lasius neglectus, which is gradually crowded out by the first species in the places of contact
