Sex Pheromone of Chilo Suppressalis: Efficient Syntheses of (Z)-11-Hexadecenal, (Z)-13-Octadecenal And (Z)-9-Hexadecenal
1996
Abstract The constituents of the sex attractant pheromone of Chilo suppressalis: (Z)-11-Hexedecenal 1, (Z)-13-octadecenenal 2 and (Z)-9-Hexadecenal 3 have been synthesized as their ethylene acetals 19, 15 and 13, in six steps from easily available compounds. The synthetic methodology can be applied to preparative scale.
UN SISTEMA DI EARLY WARNING RELATIVO AL RISCHIO IDRAULICO FLUVIALE IN AMBITO URBANO BASATO SULLA DEFINIZIONE DI SCENARI DI EVENTO: IL CASO STUDIO DI …
2021
La progressiva espansione delle aree urbanizzate, osservata negli ultimi decenni a scala globale, ha profondamente modificato i processi di formazione e trasferimento del deflusso superficiale ed ha portato ad un considerevole aumento degli elementi esposti a rischio alluvioni. I cambiamenti climatici in atto hanno inoltre indotto un’intensificazione degli eventi meteorici, con un probabile incremento della frequenza e della severità di eventi estremi in ambito urbano come urban flood e fash flood. Secondo una recente stima da parte della Commissione Europea [1], nel periodo 1980-2017 i danni causati da disastri naturali hanno superato i 500 milioni di euro, di cui il 90% dovuti ad eventi i…

User-Centered Design of a Scenario-Based Serious Game: Game-Based Teaching of Future Healthcare
2020
A scenario-based serious game for teaching about healthcare solutions was developed and tested in multiple iterations. The serious game captures the complexity of a real-world healthcare scenario, projecting it into a “scenario system” that can be accessed by the game participants to explore and experience the playthrough of a critical healthcare situation. The aim is to teach about existing health technology, and its uses and interactions between healthcare professionals, technologies, and patients. The platform for the serious game is mobile, such that different locations can be chosen for different scenarios. Actions of the participants trigger further actions, tasks, and storyline progr…
Reconfiguration: a key to handle exceptions and performance deteriorations in manufacturing operations
2005
During a manufacturing operation, exceptions may occur dynamically and unpredictably. Their occurrence may lead to the degradation of system performance or, in the worst case scenario may interrupt the production process by causing errors in the schedule plan. This paper classifies three families of exceptions: (1) out-of-order events such as machine breakdowns, (2) operational out-of-ordinary events such as rush orders and (3) deteriorations of manufacturing resource performance such as reductions of machines' utilization. In all cases, in order to maintain an adequate level of system performance, it is necessary to detect exceptions, to diagnose them quickly and to recover them by taking …
Energy Performance and Indoor Comfort of a 1930s Italian School Building: A case study
2021
Reducing energy consumption in the building tertiary sector, which accounts for a big share of the total energy use (and related CO 2 emissions) at European and Italian level, represent a strong element of safety for the EU-28. On the other hand, it is important to improve the, often overlooked, indoor comfort conditions of Italian schools since they have a significant impact on the well-being, productivity, health and safety of their occupants. Thus, it is appropriate to take into account the combination of both needs, also in light of the climate change scenario, in order to identify adequate improvement measures and justify such economic investment. This paper brings a contribution to th…
Supporting the Sustainable Energy Transition in the Canary Islands: Simulation and Optimization of Multiple Energy System Layouts and Economic Scenar…
2021
The Canary Islands have great potential for the implementation of sustainable energy systems due to its availability of natural resources. The archipelago is not connected to the mainland electricity grid and the current generation system is mainly based on traditional fossil fuel. Therefore, the islands strongly dependent on fuel importations, with high costs due to logistics. Furthermore, due to the inadequate coverage of residential heating and cooling needs, the per capita energy consumption is far below the Spanish national average. This occurrence has inspired an intense debate on the current development model of the Canary Archipelago, which has led to the implementation of actions a…
Assessing the sustainability of small wastewater treatment systems: A composite indicator approach
2014
The assessment of the sustainability of wastewater treatment (WWT) systems has gained interest in recent years. However, most previous studies have focused on environmental and/or economic dimensions ignoring social aspects. Moreover, they tend to be based on sets of indicators rather than providing a holistic assessment. To overcome this limitation, this paper proposes an innovative methodology to assess the sustainability of WWT systems based on the development of a composite indicator embracing economic, environmental and social issues. Subsequently, the global sustainability of seven WWT technologies for secondary treatment in small communities is compared. The joint application of the …

The Messinian salinity crisis in the Mediterranean basin: A reassessment of the data and an integrated scenario
2006
Abstract After a long period of controversial debate about the interpretation of the Messinian salinity crisis (MSC), a near consensus existed since the ODP Leg 42A for a model keeping the major lines of the deep basin-shallow water model initially proposed by Hsu et al. (1973) . The knowledge of the crisis was improved since the 1995s by the availability of a very accurate astronomically calibrated timescale. The debate about its interpretation was then reactivated by several new scenarios that questioned most the major aspects of the previous classical models. The updated re-examination of the most salient features along with consideration of the hydrological requirements for evaporite de…
