On interactive multiobjective optimization with NIMBUS® in chemical process design

2005

We study multiobjective optimization problems arising from chemical process simulation. The interactive multiobjective optimization method NIMBUS®, developed at the University of Jyvaskyla, is combined with the BALAS® process simulator, developed at the VTT Technical Research Center of Finland, in order to provide a new interactive tool for designing chemical processes. Continuous interaction between the method and the designer provides a new efficient approach to explore Pareto optimal solutions and helps the designer to learn about the behaviour of the process. As an example of how the new tool can be used, we report the results of applying it in a heat recovery system design problem rela…

Energy performance evaluation of a demo solar desiccant cooling system with heat recovery for the regeneration of the adsorption material

2012

Abstract Since July 2008, a Solar Desiccant Evaporative Cooling (DEC) system has been operating as a test plant at the solar laboratory of the Dipartimento di Energia (ex DREAM) of the University of Palermo. The system is composed of an air handling unit (AHU) designed for ventilation of the laboratory coupled with a radiant ceiling that provides most of the required sensible cooling/heating energy. Flat plate collectors deliver part of the regeneration heat of the desiccant wheel during the summertime and are used for space heating during the wintertime. The system was designed for high humidity loads because of the typical climate conditions at the site and the need to support a radiant c…

Energy and economic assessment of desiccant cooling systems coupled with single glazed air and hybrid PV/thermal solar collectors for applications in…

2009

Abstract This paper presents a detailed analysis of the energy and economic performance of desiccant cooling systems (DEC) equipped with both single glazed standard air and hybrid photovoltaic/thermal (PV/t) collectors for applications in hot and humid climates. The use of ‘solar cogeneration’ by means of PV/t hybrid collectors enables the simultaneous production of electricity and heat, which can be directly used by desiccant air handling units, thereby making it possible to achieve very energy savings. The present work shows the results of detailed simulations conducted for a set of desiccant cooling systems operating without any heat storage. System performance was investigated through h…

Gaming as a Key Approach for the Recovery Process of a Public Space: The Case Study of the Old Chemical Plant ‘Chimica Arenella’ in Palermo

2021

This poster describes the FORGE (FactOry of uRban GamEs) project, a proposal that our research group launched in partnership with the Municipality of Palermo (Italy) and other local stakeholders in 2019. FORGE will be hosted in what was previously a chemical plant (the former 'Chimica Arenella') and is an open factory designed to collect needs and to generate interventions for urban innovation. The four key terms we have used for the project are urban, game, factory and participation. In fact, FORGE employs a participatory methodological model based on the concept of game, aimed at supporting social and economic development through a platform for participatory co-design. FORGE plays also a …

NEMATODE COLONIZATION OF PYRITE CINDER-POLLUTED SOIL

2020

The nematofauna was studied in the early stages of a remediation trial at an industrial site where pyrite cinders had accumulated for 40 years in a large area and were then covered with mineral soil. The cinders were contaminated with several metals and metalloids. The soil of the experimental plots was derived from the mixture of cinders with the covering soil in a 1:1 ratio. Plots were amended with manure and sown with 3 metal resistant plants: Sorghum bicolor L., Helianthus annuus L., and Arundo donax L. Samples were taken : a) at the beginning of the trial on the pyrite cinders and covering soil, separately; b) from the mixture before the application of manure; c) from cultivated plots.…

Edilizia abusiva a Favara. Analisi dell’insediamento e sviluppo del territorio

2007

Il Piano Regolatore Generale, strumento di fondamentale importanza per lo sviluppo di un centro urbano e del suo territorio, è ancora per diverse città siciliane un obiettivo da raggiungere. I dati provenienti dall'Assessorato Regionale al Territorio e Ambiente (A.R.T.A.) indicano una Sicilia decisamente indietro nella progettazione urbanistica. Nell'isola soltanto il 40,3% dei comuni hanno un piano regolatore vigente. La mancata approvazione degli strumenti urbanistici ha influito negativamente sui processi di urbanizzazione, spesso frammentari e disorganici. Le città si sono sviluppate senza una forma, un modello riconoscibile, alimentando nei cittadini una politica che ha preferito l’edi…

Blocking NMDA-receptors in the pigeon's "prefrontal" caudal nidopallium impairs appetitive extinction learning in a sign-tracking paradigm

2015

Extinction learning provides the ability to flexibly adapt to new contingencies by learning to inhibit previously acquired associations in a context-dependent manner. The neural networks underlying extinction learning were mostly studied in rodents using fear extinction paradigms. To uncover invariant properties of the neural basis of extinction learning, we employ pigeons as a model system. Since the prefrontal cortex of mammals is a key structure for extinction learning, we assessed the role of N-methyl-D-aspartate receptors (NMDARs) in the nidopallium caudolaterale, the avian functional equivalent of mammalian prefrontal cortex. Since NMDARs in prefrontal cortex have been shown to be rel…

MR imaging of bilateral paramedian thalamic and mesencephalic infarcts: A case report

2010

We describe MR imaging of bilateral infarction of the paramedian portion of the mesencephalus and thalamus due to an occlusion of the Percheron artery. This entity is due to one of the anatomic variants of the perforating arteries supplying the thalamus and mesenchephalus. Clinically this kind of infarction presents with neurologic impairment as a disorder of consciousness, memory dysfunctions, various types of vertical gaze palsy and psychic changes, which need to be differentiated from delirium and coma. At MRI evaluation infarction of the paramedian portion of thalami and midbrain, with a “butterfly wings” pattern, was demonstrated as high signal intensity areas on FLAIR and FSE-T2W ima…
