Nuove acquisizioni documentali su villa Valguarnera a Bagheria (Palermo)
2018
A palazzo Valguarnera-Gangi di Palermo è stato fortuitamente rinvenuto il “libro di fabrica del casino della Bagaria” (1712-1779), da considerare un prezioso “frammento” del disperso archivio Valguarnera. Rispetto al corpus documentario già noto questo ritrovamento contribuisce in modo sostanziale alla messa in luce delle lunghe fasi di completamento della villa. New documentary findings on Villa Valguarnera in Bagheria (Palermo) At Valguarnera-Gangi palace in Palermo it was fortuitously found the “libro di fabrica del casino della Bagaria”; namely a volume including documents relating to the construction of villa Valguarnera in Bagheria (1712-1779), to be considered as a precious “fragment…
La reinterpretación del sonido de la metrópoli en las sinfonías urbanas
2023
Las sinfonías urbanas de la vanguardia cinematográfica reflejaron el pensamiento estético y filosófico del momento. La historiografía ha recalcado la trascendencia de la imagen, la técnica del montaje y el universo simbólico o el formal, pero ha desatendido, en cierta forma, el alcance de la banda sonora. El debate planteado por Schopenhauer, Valery o Benjamin sobre la percepción del ruido y del sonido fue un aspecto valorado en las composiciones musicales que buscaron la reinterpretación y la reproducción del ambiente de la metrópoli. El citadino estaba sometido a un sinfín de estímulos marcados por un ritmo frenético según Nietzsche y Simmel. Las sinfonías y documentales coetáneos inspira…
Legislative reforms and market dynamics in the provision of urban water service by private contract operators in Spain
2022
Abstract This paper studies the dynamics of concentration in the Spanish market for the provision of urban water service by private contract operators in the 2000–2020 period. The market is highly concentrated. Concentration increased until 2007, at which point it started to decline when Law 30/2007 on Public Sector Contracts and Organic Law 8/2007 on Political Party Financing were passed; before rising again from 2016 onwards. This latter trend results from strategic behaviour by the two leading operators, acquiring smaller companies with a notable presence in some regional markets. Further legislative reforms aimed at safeguarding space for competition are thus proposed.
Theoretics and Methodology
2016
Since 2000 in Europe an integrated management framework has been developed to innovate exploitation and safeguard of water resources. In this context the EU Water Framework Directive has identified the hydrographic basin as the optimal territorial unit for promoting new participatory policies, based both on the interaction of stakeholders and the coordination of sectorial instruments. In this scenario, river contracts assumed a strategic role both in addressing these purposes and supporting the dialogue and integration between interests of public and private stakeholders. This chapter illustrates the theoretical and methodological framework, and the comparative approach on which the researc…
Toward the Identification of Two Glycoproteins Involved in the Stomatal Deregulation of Downy Mildew–Infected Grapevine Leaves
2015
SPE Pôle IPM UB; International audience; Stomata remain abnormally opened and unresponsive to abscisic acid in grapevine leaves infected by downy mildew. This deregulation occurs from 3 days post inoculation and increases concomitantly with leaf colonization by the pathogen. Using epidermal peels, we demonstrated that the active compound involved in this deregulation is located in the apoplast. Biochemical assays showed that the active compound present in the apoplastic fluids isolated from Plasmopara viticola infected grapevine leaves (IAF) is a CysCys bridge-independent, thermostable and glycosylated protein. Fractionation guided assays based on chromatography / stomatal response and prot…
Trehalose and trehalose-6-phosphate induce stomatal movements and interfere with ABA-induced stomatal closure in grapevine
2015
Aims: The effects of trehalose and trehalose-6-phosphate (T6P), among other sugars, were assessed on grapevine stomatal movements. Methods and results: Epidermal peels were used to assess the effects of sugars. Low concentrations of trehalose and T6P (1 μM) induced an osmotic-independent reduction of the stomatal aperture in light conditions. Furthermore, ABA-induced stomatal closure was reduced by sugar application in association with lower accumulation of reactive oxygen species in guard cells. Similar effects, although weaker, were observed in response to the disaccharides sucrose and maltose, but not in response to the monosaccharides fructose and glucose. Conclusion: This study clearly…
Reliable numerical solution of a class of nonlinear elliptic problems generated by the Poisson-Boltzmann equation
2020
We consider a class of nonlinear elliptic problems associated with models in biophysics, which are described by the Poisson-Boltzmann equation (PBE). We prove mathematical correctness of the problem, study a suitable class of approximations, and deduce guaranteed and fully computable bounds of approximation errors. The latter goal is achieved by means of the approach suggested in [S. Repin, A posteriori error estimation for variational problems with uniformly convex functionals. Math. Comp., 69:481-500, 2000] for convex variational problems. Moreover, we establish the error identity, which defines the error measure natural for the considered class of problems and show that it yields computa…
CITTA’ ABUSATE: TECNOLOGIE E STRATEGIE PER LA GESTIONE DEL COSTRUITO
2010
Il contributo riporta parte dei risultati di una ricerca sulle tecnologie di recupero degli ambienti degradati e le strategie di valorizzazione del patrimonio. Il processo di ricerca - supportato da un virtuoso confronto interdisciplinare - ha ampliato il raggio di azione nei contesti della Grecia (grazie alla collaborazione con l'Istituto Archeologico dell'Egeo, del Ministero della Cultura Ellenico, Rodi, Grecia) e del Sud Italia, per ulteriori verifiche e approfondimenti su realtà fenomenologiche parallele. Sulla scorta degli studi in itinere questo contributo inquadra il fenomeno in via generale, rilevando tempi, modi e luoghi dell’abusivismo, introducendo, sia gli aspetti giuridici ed u…
Accessibilità e fruizione delle raccolte
2015
Il contributo fa il punto sulla formazione universitaria nel campo dei beni culturali, evidenziando il progressivo depauperamento degli ambiti inerenti, in particolare, il patrimonio archivistico e bibliotecario, attraverso un esame dei dati MIUR e la comparazione dell'offerta formativa degli atenei. Viene evidenziato il nesso indispensabile tra la formazione specialistica e la possibilità di tutelare e valorizzare, consentire l'accessibilità e rendere 'pubblico' il patrimonio - secondo l'istanza che proviene da più parti, e che riguarda l'intero patrimonio culturale nelle sue varie forme e declinazioni -, facendone oggetto di una reale condivisione, necessariamente mediata dagli specialist…
