Henstock–Kurzweil–Pettis integrability of compact valued multifunctions with values in an arbitrary Banach space
2013
Abstract The aim of this paper is to describe Henstock–Kurzweil–Pettis (HKP) integrable compact valued multifunctions. Such characterizations are known in case of functions (see Di Piazza and Musial (2006) [16] ). It is also known (see Di Piazza and Musial (2010) [19] ) that each HKP-integrable compact valued multifunction can be represented as a sum of a Pettis integrable multifunction and of an HKP-integrable function. Invoking to that decomposition, we present a pure topological characterization of integrability. Having applied the above results, we obtain two convergence theorems, that generalize results known for HKP-integrable functions. We emphasize also the special role played in …
Mechanical Tests on Innovative BIPV Façade Components for Energy, Seismic, and Aesthetic Renovation of High-Rise Buildings
2018
The paper shows the results of mechanical tests carried out on prototypes of a new Building Integrated Photovoltaic (BIPV) component developed by the author and SBskin Smart Building Skin s.r.l. This patented innovative component is able to merge structural function, insulation proprieties, and production of clean energy for retrofit actions and/or the construction of translucent faç
A Multifunctional Public Lighting Infrastructure, Design and Experimental Test
2017
Nowadays, the installation of efficient lighting sources and Information and Communications Technologies can provide economic benefits, energy efficiency, and visual comfort requirements. More advantages can be derived if the public lighting infrastructure integrates a smart grid. This study presents an experimental multifunctional infrastructure for public lighting, installed in Palermo. The system is able to provide smart lighting functions (hotspot Wi-Fi, video-surveillances, car and pedestrian access control, car parking monitoring and support for environmental monitoring). A remote control and monitoring platform called “Centro Servizi” processes the information coming from…
A multifunctional plant for a sustainable reuse of marble waste toward circular economy
2021
The marble processing cycle involves the production of large quantities of wastes whose disposal represents an economic and environmental concern for marble companies due to the difficulty of identifying suitable landfills and the high transfer costs. In this context, the design of a sustainable industrial plant that allows the reuse of the calcium carbonate (CaCO3) contained in the marble waste is extremely challenging. With this recognition, the main industrial applications of CaCO3 are firstly analyzed in the present work to identify the physical–chemical properties required to CaCO3 in these contexts. Later, different plant solutions are suggested to recover CaCO3 from marble sludge in…
Primo Convegno Nazionale della Società dei territorialisti e delle territorialiste: tra approccio multidisciplinare, ritorno alla terra, valore umano…
2014
Prendendo spunto dal Primo Convegno Nazionale della Società dei Territorialisti e delle Territorialiste, che ha avuto luogo a Milano nei giorni del 17 e 18 maggio 2013, si riflette e si ripercorre la via che ha portato la pianificazione territoriale da un approccio al territorio per parti separate a quello di una lettura e progettazione di tipo sistemico ed organico che mira al superamento della precedente settorialità: l’approccio territorialista. La visione e il metodo territorialista implementa la multidisciplinarietà propria della pianificazione territoriale coinvolgendo l’identità dei luoghi, la partecipazione degli abitanti, la produzione sociale e condivisa di paesaggi, la proposta d…
New Hybrid Organic-inorganic Multifunctional Materials Based on Polydopamine-like Chemistry
2021
Taking inspiration from the chemistry of dopamine, a simple and economic synthetic approach toward the synthesis of a series of silica-based polydopamine-like materials has been developed. Mild conditions and easy manipulation are the strongest aspects of this methodology. Such hybrid materials were successfully used as recyclable catalysts for Knoevenagel reactions.
Optical Gating of Photosensitive Synthetic Ion Channels
2011
4-oxo-4-(pyren-4-ylmethoxy) butanoic acid is used as a photolabile protecting group to show the optical gating of nanofluidic devices based on synthetic ion channels. The inner surface of the channels is decorated with monolayers of photolabile hydrophobic molecules that can be removed by irradiation, which leads to the generation of hydrophilic groups. This process can be exploited in the UV-light-triggered permselective transport of ionic species in aqueous solution through the channels. The optical gating of a single conical nanochannel and multichannel polymeric membranes is characterised experimentally and theoretically by means of current-voltage and selective permeation measurements,…
What future for decommissioned historic irrigation canals? Crafting new identities in the Lower Ter (Spain)
2020
Historic irrigation canals are valuable socioecological systems capable of delivering several ecological and cultural services. However, ecological modernisation initiatives are leaving decommissioned ditches in limbo. A case study strategy is used to analyse the history of a decommissioned 700-year-old canal network in northeastern Spain and the unexpected intervention of several stakeholders who have attempted to redefine the former canals through new uses. The study relies on the analysis of documents and eight semistructured interviews with key stakeholders. We argue that this case reflects a policy failure in the application of multifunctionality, integrative planning and social partic…
Territori Rurali Ri-attivati. Multifunzionalità, fruizione e impegno sociale attraverso l'esperienza della Cooperativa Sociale "Lavoro e Non Solo"
2012
Poster che sintetizza l'esperienza della Cooperativa Sociale "Lavoro e Non Solo", operante in aree agricole e su beni confiscati alla criminalità organizzata nei comuni siciliani di Corleone, Monreale, Canicattì, San Giuseppe Jato. Il caso si presta a rappresentare bene il concetto di multifunzionalità in agricoltura. È stato presentato durante il I Convegno nazionale della Società dei territorialisti/e, a Milano, in data 17 e 18 maggio 2013
Multipore membranes with nanofluidic diodes allowing multifunctional rectification and logical responses
2016
[EN] We have arranged two multipore membranes with conical nanopores in a three-compartment electrochemical cell. The membranes act as tunable nanofluidic diodes whose functionality is entirely based on the pH-reversed ion current rectification and does not require specific surface functionalizations. This electrochemical arrangement can display different electrical behaviors (quasi-linear ohmic response and inward/outward rectifications) as a function of the electrolyte concentration in the external solutions and the applied voltage at the pore tips. The multifunctional response permits to implement different logical responses including NOR and INHIBIT functions.
