The sirocco chambers: passive cooling structures in the XVI century Palermo area
2014
In the past centuries, the plain surrounding the city of Palermo saw the construction of tens of suburban manor houses, called villas, which were referred to as “places of delight” for the amenities they offered during the good season. These architectural machines were built by aristocrats to make living in the countryside more pleasant and to exhibit their families’ richness and power. Among the delights, the Sirocco rooms were very common in Palermo from the Renaissance, and especially beyond to the XVIII century. They were artificial subterranean structures, built close to a water spring in order to reproduce the pleasant conditions of freshness that could be experienced in a natural cav…
Smart Technology for the passive house
2013
Planning for sustainable policies aimed at identifying Smart urban spaces is determined by the parameters of Smart Cities model that encourage the production of intelligent building for construction energy efficient. The proposed article analyzes the effectiveness of the passive house in the Mediterranean area, offered by traditional building techniques, proposing a re-reading technology for the detection of a smart design methodology that can lead to the use of technologies with high energy efficiency.
Development of microfluidics for sorting of carbon nanotubes
2018
Sorting of carbon nanotubes by their chirality is the current bottleneck in the way to their broad employment based on their exceptional electronic and optical properties. Despite the extensive effort, there is no known method, which would result in really pure chirality ensembles. Previously reported sorting protocols result in enrichment rather than in sorting, alter electronic structure, and suffer from low yield. This is mostly due to the statistical approach, where the nanotubes with mixed chiralities are treated as a set. In this thesis, we propose a new sorting technique based on nanotube-by-nanotube compartmelization, characterization, and sorting in a continuously running droplet-b…
I sistemi ibridi nella progettazione dell’edilizia sostenibile
2010
La memoria si inserisce nel volume dedicato alla commemorazione del prof. Benedetto Colajanni e, in particolare, prende spunto da uno degli ultimi eventi in cui il prof. Colajanni è intervenuto in occasione delle giornate organizzate dall'associazione Ar.Tec. per il 2° Convegno dal titolo: Intervenire sul patrimonio edilizio: cultura e tecnica, che si è svolto a Torino dal 9 all'11 novembre 2006. Durante il dibattito relativo alla sessione “Acquisizione di conoscenza e criteri di scelta progettuale” il prof. Colajanni ha affrontato il tema della sostenibilità: un argomento delicato di grande rilevanza per il ruolo strategico che assume oggi nella società, dando, come di solito gli era conge…

Reconsidering passivity and activity in children’s digital play
2016
The discussion around children’s digital game culture has resulted in two contradictory images of children: the passive, antisocial children uncritically and mechanically consuming digital game content and the active, social children creatively using and interacting with digital game content. Our aim is to examine how these seemingly contradictory ideas of “active” and “passive” children could be considered. By means of empirical examples of children playing digital dress-up and makeover games, we will point out that for the successful use of these concepts, they need to be thoroughly contextualized. By discussing the context and referent of activity and passivity, it is possible to overcom…
Presentation of the English passive in four Finnish upper secondary school EFL textbooks
2013
Kieliopin opettaminen on alusta alkaen ollut keskeinen osa nykyaikaista vieraiden kielten opetusta. Mielipiteitä siitä, kuinka kielioppi määritellään, kuinka sitä tulee opettaa ja onko sen opettaminen ylipäätään tarpeen, on esitetty lukemattomia. Tässä tutkielmassa on omaksuttu Thornburyn (1991:1) määritelmä kieliopista tietyn kielen erilaisten mahdollisten rakenteiden ja muotojen tutkimuksena. Kieliopin opetuksen historiaa tarkastellaan kolmen keskeisen vaiheen kautta. Tutkielmassani tarkastellaan neljän suomalaisen lukiotason A1-englannin oppikirjan osioita, joissa käsitellään passiivia. Tavoitteena on ollut löytää yhtäläisyyksiä ja eroja tavoissa, joilla passiivi esitellään opiskelijoill…
Formation of Si/SiO2 Luminescent Quantum Dots From Mesoporous Silicon by Sodium Tetraborate/Citric Acid Oxidation Treatment
2019
We propose a rapid, one-pot method to generate photoluminescent (PL) mesoporous silicon nanoparticles (PSiNPs). Typically, mesoporous silicon (meso-PSi) films, obtained by electrochemical etching of monocrystalline silicon substrates, do not display strong PL because the silicon nanocrystals (nc-Si) in the skeleton are generally too large to display quantum confinement effects. Here we describe an improved approach to form photoluminescent PSiNPs from meso-PSi by partial oxidation in aqueous sodium borate (borax) solutions. The borax solution acts to simultaneously oxidize the nc-Si surface and to partially dissolve the oxide product. This results in reduction of the size of the nc-Si core …
Economic and Life Cycle Analysis of Passive and Active Monitoring of Ozone for Forest Protection
2021
At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of moni…
