Vapor–liquid equilibria in dendrimer and hyperbranched polymer solutions: experimental data and modeling using UNIFAC-FV
2004
Abstract This work evaluates the potential of the group contribution method universal functional activity coefficients-free-volume (UNIFAC-FV) to predict vapor–liquid equilibria (VLE) in dendrimer-solvent and hyperbranched polymer-solvent systems. The VLE of hydroxyl-functional dendritic polymers (polyethers, polyesters, polyamidoamine), dissolved in polar solvents (ethanol and/or water) are studied both experimentally and theoretically. A new approach is suggested to account for the contribution of selected types of polymer structural units (i.e. linear, dendritic and terminal units) to the solvent residual activity. The results of calculations are in a good agreement with experiment. Furt…
Teachers and inclusion: an empirical survey on specialist training for support teachers
2019
This paper illustrates the results of an empirical-experimental research conducted as part of the Specialization Course for support activities, held at the University of Palermo in the academic year 2016/17. The survey, concerning the effectiveness of training courses for teachers for the development of active learning, involved 450 teachers and had the main objective of investigating whether there was an actual increase in specific professional skills functional to school inclusion among those who attended the course. Despite leading to different kinds of meaningfulness, the pre/post-test data are evidence of a general positive improvement, highlighting how a student-centred approach has a…
AMBIENTE COSTRUITO E SOSTENIBILITÀ – Materiali riciclati e Design for Disassembly tra ricerca e buone pratiche
2020
In the context of environmental emergency of which the construction sector is one of the main causes – since it consumes 40% of the (embodied and operational) energy and produces about a third of the total waste – and due to the ambitious objectives set by the international community and by many countries to reduce the environmental impact of buildings during their whole life cycle, this paper wants to make a contribution to the understanding of the state of the art on cycle-based research activities, sustainable experiments and good practices that the building industry and the academy have implemented in recent years. In particular, it refers to cycle-based theoretical and experimental act…

Interpersonal Distance in the SARS-CoV-2 Crisis
2020
Background Mandatory rules for social distancing to curb the SARS-CoV-2 pandemic require individuals to maintain a critical interpersonal distance above 1.5 m. However, this contradicts our natural preference, which is closer to 1 m for non-intimate encounters, for example, when asking a stranger for directions. Objective This review addresses how humans typically regulate interpersonal distances, in order to highlight the challenges of enforcing atypically large interpersonal distances. Method To understand the challenges posed by social distancing requirements, we integrate relevant contributions from visual perception, social perception, and human factors. Results To date, research on pr…

La participación de la ciudadanía en los procesos de diseño de las políticas públicas de empleo. El caso del litoral sur de Alicante
2019
La presente investigación tiene como finalidad describir cómo la ciudadanía ha contribuido a la elaboración de un Diagnóstico Territorial de Empleo (DET) promovido por la Generalitat Valenciana, previo al diseño de futuras políticas públicas para el fomento del empleo, en tres municipios alicantinos. Se consiguió a través de una Investigación-Acción-Participación (IAP). Se realizaron talleres participativos y grupos focales que sirvieron para que la ciudadanía conociese de la existencia del proyecto y sus fines, además de aportar su experiencia, opinión y plantear posibles soluciones a la problemática del empleo en estos municipios. Se puede concluir que la ciudadanía está capacitada para a…
Study of liquid–liquid equilibrium of the systems isobutyl acetate+acetic acid+water and isobutyl alcohol+acetic acid+water at different temperatures
2008
Abstract In this work, experimental liquid–liquid equilibria (LLE) data of the systems isobutyl acetate + acetic acid + water and isobutyl alcohol + acetic acid + water are presented. The liquid–liquid equilibria of both systems have been measured at 283.15 and 323.15 K. The NRTL and UNIQUAC models were applied to fit the data for both ternary systems. The interaction parameters obtained from both models successfully correlated the equilibrium compositions. The experimental tie lines were compared to the values predicted by the UNIFAC method. Moreover, the solvent capabilities of isobutyl acetate and isobutyl alcohol were compared.
The Large Hadron–Electron Collider at the HL-LHC
2021
The Large Hadron-Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron-proton and proton-proton operations. This report represents an update to the LHeC's conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LH…
