Tattiche di agopuntura adattiva
2015
Il contributo riporta gli esiti del workshop internazionale di progettazione urbana "PMO | Re-verse. Hyper-cycling Costa Sud", organizzato nell'ambito del PRIN "Re-cycle Italy. Nuovi cicli di vita per architetture e infrastrutture della città e del paesaggio", che si è tenuto a Palermo dal 9 al 13 settembre 2013. Nello specifico, l'articolo descrive le elaborazioni del gruppo di studenti e professionisti - da me seguito in qualità di tutor - che hanno sperimentato un processo di rigenerazione della costa sud di Palermo adottando la tattica progettuale dell'agopuntura urbana, arricchendola di considerazioni originali sulla ciclicità delle possibili funzioni costiere.
DIALOGO SU FARM CULTURAL PARK
2015
Farm Cultural Park è oggi un esempio di rigenerazione urbana riconosciuto in tutto il mondo, che si arricchisce ogni giorno di nuovi progetti e iniziative e a cui aderiscono sempre più artisti, professionisti e creativi. Proprio in virtù di questa unicità, l'UdR di Palermo del PRIN "Re-cycle Italy. Nuovi cicli di vita per architetture e infrastrutture della città e del paesaggio", ha voluto presentare questa buona pratica - caso esemplare di "re-cycle" - all'interno della ricerca di interesse nazionale, descrivendola attraverso le parole del suo stesso fondatore. Il contributo, pertanto, sotto forma di dialogo, racconta l'idea, il processo e i futuri di Farm Cultural Park.
Cancer cell(s) cycle sequencing reveals universal mechanisms of apoptosis
2010
In this paper, cell cycle in higher eukaryotes and their molecular networks signals both in G 1/S and G2/M transitions are replicated in silico. Biochemical kinetics, converted into a set of differential equations, and system control theory are employed to design multi-nested digital layers to simulate protein-to-protein activation and inhibition for cell cycle dynamics in the presence of damaged genomes. Sequencing and controlling the digital process of four micro-scale species networks (p53/Mdm2/DNA damage, p21mRNA/cyclin-CDK complex, CDK/CDC25/wee1/ SKP2/APC/CKI and apoptosis target genes system) not only allows the comprehension of the mechanisms of these molecule interactions but paves…
Environmental assessment of 2030 electricity generation scenarios in Sicily: An integrated approach
2020
Abstract This paper deals with the environmental assessment of two electricity scenarios in Sicily, for 2030, characterized by a high exploitation of renewable energy sources in order to quantify the potential contribution of the local strategies in the achievement of the European climate policies and the potential improvement in the future electricity mix, compared to the current one (2014). In order to match these goals, authors integrate the Life Cycle Assessment with a scenario analysis. The future electricity mix scenarios, characterized by a share of renewables (57% for 2030-BS scenario and 51% for 2030-DS scenario) show a reduction of the greenhouse gases emissions per kWh of electri…
From biomass waste to tri-generation: a life-cycle experience in the “agro-combined” of Thibar
2018
The paper presents a Life Cycle Assessment of the energy tri-generation from biomass waste in a plant located in Tunisia. The analysis included the plant construction and end-of-life, the supply of biomass, its use for biogas production and the electricity, heating and cooling generation from biogas. The study is one of the first applications of environmental analysis to tri-generation from biomass waste in developing countries. The results showed that the plant construction is responsible of 76% of primary energy consumption and gives a contribution higher than 88% on resource depletion and ionising radiation. The operation causes 66% of the impact on human toxicity - cancer effects and mo…
Multi-Objective Building Envelope Optimization through a Life Cycle Assessment Approach
2019
This work describes a methodology for the identification of the optimal features for the envelope of a residential building. The optimization process allows minimizing operating energy consumption, investment costs and life cycle energy and environmental embodied impacts. A dynamic model for the estimation of building energy consumption during its use phase has been employed, while literature data were adopted for embodied energy and global warming potential impacts. The considered variables refer to the envelope of the building, i.e. external walls and roof insulation and external walls thermal mass. The model was obtained combining EnergyPlus building energy simulator and MOBO, a versatil…
Electric mobility in Sicily: An application to a historical archaeological site
2016
Transports should be a key focus in the close future for decarbonization efforts, if the optimistic climate change mitigation objectives to be reached by 2050 on a global scale are to be met. Choosing an emblematic and historical location in the center of Sicily as object of the study, the potential for decarbonization and the reduction of the energy and environmental impacts in the site for electric mobility is assessed, by considering electric mobility scenarios based on different shares of electricity generated through renewable energy technologies. The analysis is performed by means of a life-cycle approach, through the use of the Life Cycle Assessment methodology. A parametric analysis…
Second life employment of a traction battery for load match optimisation of a residential building: Life cycle and operation applications
The increasing use of renewable energy technologies for the electricity generation in buildings will require a growing number of energy storage systems (ESSs) in the next years in order to reduce the mismatch between the highly variable on-site electricity generation and the building load. Retired electric vehicle batteries (EVBs), before recycling, can be used for this purpose, considering that they have about 80% of the original energy capacity. In this context, the study aims at examining an ESS made by retired EVBs, in order to identify its optimal size for reducing the mismatch in a net zero energy building equipped with a photovoltaic plant and to assess the life cycle energy and envi…
Life-Cycle Assessment Applied to Future Scenarios of Electricity Generation in Sicily
2018
Fighting global warming and increasing the energy security are some of the most relevant objectives of the European energy policy. Thus, defining potential low carbon pathways for the energy sector is of paramount importance in order to identify strategies with the lowest impact on climate. This paper presents an overview of environmental assessment of future electricity scenarios in Sicily (Italy), for 2020 and 2030, characterized by a high exploitation of renewable energy sources. Authors apply the Life Cycle Assessment methodology, according to the standard of the ISO 14040 series, in order to evaluate the environmental impacts of electricity generation in the future scenarios in compari…
