'900: TECNOLOGIA REVERSIBILE PER UN ALLESTIMENTO CON LE RUOTE
2014
Per celebrare l’Unità d’Italia nel suo 150° ha preso il via da Palermo al Real Albergo delle Povere una mostra voluta dal Ministero per lo Sviuppo. Negli obiettivi, la volontà di realizzare una mostra che, non solo itinerante, applicasse l’uso di tecnologie innovative, sia removibili sia reversibili. Oggetto del presente contributo è chiarire come sin dal progetto sia possibile definire, attraverso l’uso appropriato della tecnologia a secco, ambienti, spazi e scenari adattabili di volta in volta a luoghi diversi. A Palermo il test della mostra ’900 ha dimostrato l’efficacia realizzativa potendo poi la stessa esser trasportata in altre città internazionali senza lo spreco di un solo elemento.
Readers’ Theater Projects for Special Education : A Randomized Controlled Study
2022
A randomized controlled trial was conducted to study the effectiveness of two readers’ theater (RT) programs in promoting reading skills and motivation of dysfluent readers in Grades 3–4. One program (RT Goal) included a goal of preparing a performance for an audience (n = 50), while another program (RT Practice) did not include such a goal (n = 49). A group of dysfluent readers receiving traditional oral reading intervention (Control group; n = 59) and a group of classroom peers (Mainstream group; n = 159) served as controls. The results indicate that both RT groups and the Control group developed at a higher rate in oral reading speed during the intervention period than the Mainstream gro…
Design and Performance Evaluation of a High Power-Density EMI Filter for PWM Inverter-Fed Induction-Motor Drives
2016
This paper presents the design of an electromagnetic interference (EMI) filter for a low-voltage high-current induction-motor drives supplied by dc power grids. In order to effectively design the EMI filter, a suitable common-mode/differential-mode (CM/DM) separation technique has been used. Due to the high operating currents, the software-based separation technique using time-domain measurements has been applied. The proposed technique allows the CM and DM sections of the EMI filter to be properly selected in a more economical way, i.e., without the need of a dedicated hardware or costly radio frequency (RF) instrumentation. The design has been done according to a power-density criterion. …
Dampness and student-reported social climate: two multilevel mediation models.
2021
Background Little previous research has analysed the relationship between schools' indoor air problems and schools' social climate. In this study, we analysed a) whether observed mould and dampness in a school building relates to students' perceptions of school climate (i.e. teacher-student relationships and class spirit) and b) whether reported subjective indoor air quality (IAQ) at the school level mediates this relationship. Methods The data analysed was created by merging two nationwide data sets: survey data from students, including information on subjective IAQ (N = 25,101 students), and data from schools, including information on mould and dampness in school buildings (N = 222). The …

Path creation is a key concept in economic geography. So far, particularly scholars within evolutionary economic geography have pioneered research on this topic. This paper critically discusses the...
A multi-objective and multi-criteria approach for district metered area design: water operation and quality analysis
2019
Water distribution network (WDN) operation may be improved by district metered area (DMA) design [1]. A first step to create DMAs uses graph theory and non-supervised learning, where physical features of the WDN, such as node coordinates, elevation and demand, are used for clustering purposes [2]. A second step is related to the necessary isolation of the clustered elements. For isolation purposes, it is important to determine the DMA entrances and, consequently, the needed cut-off valves. Closure of pipes and definition of DMA entrances can be set as an optimization problem with the costs associated to the valves, which are linked to pipe diameters, as a primary objective. However, placeme…
La importància del coneixement de les eixides professionals en Relacions Laborals
2010
L’objectiu és presentar un projecte la finalitat del qual ha estat mostrar als estudiants de primer de Relacions Laborals quines són les principals eixides professionals, les competències i habilitats requerides per les esmentades eixides i la seua vinculació amb les matèries objecte d’estudi de la titulació. El projecte està especialment dirigit al grup d'estudiants que ha seguit el Projecte d'Innovació Educativa (PIE) durant el període 2005-2009. Per això s’ha comptat amb la participació en aquest projecte del professorat que havia impartit docència al PIE i també amb un grup de professionals externs a la universitat, directament vinculats amb aquestos estudis. Aquestos professionals van …
Multinationals, R&D and productivity: Evidence for UK Manufacturing firms
2010
In this study, we analyze multinationality (domestic-based firms versus multinationals) and foreignness (foreign versus domestic firms) effects in the returns of R&D to productivity. We follow a two-step strategy. In the first step, we consistently estimate firm's productivity by GMM and numerically compute the sample distribution of the R&D returns. In the second step, we use stochastic dominance techniques to make inferences on the multinationality and foreignness effects. Results for a panel of UK manufacturing firms suggest that multinationality and foreignness effects operate in an opposite way: whilst the multinationality effect enhances R&D returns, the foreignness diminishes them. C…
Hydrothermal liquefaction of municipal sludge in sub- and super- critical water
2020
Hydrothermal liquefaction of municipal sludge was conducted to investigate the effects of sub- and supercritical water and of the fluid dynamic regime on the quality of the products. Preliminary experimental runs were performed at two different temperatures (350°C and 400°C) changing reaction time in order to work at fixed kinetic severity of the process. An improvement of the C content in the solid residues and of the ratio H/C of the biocrude was obtained when a stirred reactor was used both in sub- and supercritical water. A hydrocarbon fraction was separated from biocrude whose maximum yield of 25% w/w was achieved in supercritical conditions. Results showed that the cumulative energy r…
