Wastewater-based epidemiology for early warning of SARS-COV-2 circulation: A pilot study conducted in Sicily, Italy
2022
There is increasing evidence of the use of wastewater-based epidemiology to integrate conventional monitoring assessing disease symptoms and signs of viruses in a specific territory. We present the results of SARS-CoV-2 environmental surveillance activity in wastewater samples collected between September 2020 and July 2021 in 9 wastewater treatment plants (WTPs) located in central and western Sicily, serving over 570,000 residents. The presence of SARS-CoV-2, determined in 206 wastewater samples using RT-qPCR assays, was correlated with the notified and geo-referenced cases on the areas served by the WTPs in the same study period. Overall, 51% of wastewater samples were positive. Samples we…
Numerical simulation of wave energy production through experimental tool
2017
Wave energy is highly desirable resource and recent international reports underline its major relevance on global renewable energy in future. In general, the first step is a correct WEC (Wave Energy Converter) sizing and design. The aim of this paper is a presentation of an application of one experimental tool to define the external floating structure of WEC realized by University of Palermo. This new electric device could be another energy possibility for small islands in the Mediterranean Sea as Pantelleria, Lampedusa or Malta.
Off-axis focal shift for rotationally nonsymmetric screens
2009
We report on an analytical formulation for evaluating the amplitude distribution along any line directed toward the geometrical focus of a spherical wave front that passes through a rotationally nonsymmetric diffracting screen. Our formula consists of two factors. The first factor involves the one-dimensional Fourier transform of the projection of the screen function onto the off-axis line. The second factor depends on the inverse distance to the screen and permits us to recognize the existence of focal shift along off-axis lines.
Multicomponent line profile restoring by means of ill-posed inverse task solution
2017
The investigation of the criteria of usage of the Tikhonov regularization method for multicomponent overlapping line profiles restoring was done by means of model task solution. The influence of the width and kind of the instrumental function, number of the components of the profile and distance between components are discussed.
Arquitectura blanca : la poética contemporánea
2023
L’esperienza del bianco in architettura è un racconto di permanenza di principi antichi (quasi primordiali), di tradizioni vere o presunte che si innovano progressivamente, di circolarità di idee e culture che si contaminano reciprocamente, per sommarsi e trovare la loro espressione nello stesso colore. Nella continuità di queste esperienze, il mito del bianco continua e si rinnova: nel tempo, definendosi come un nuovo carattere della contemporaneità; nello spazio, diventando un elemento esteso e condiviso di una koinè globale. Il panorama contemporaneo dell'architettura bianca, che in un’osservazione superficiale può sembrare omogeneo, esprime in verità i diversi significati che il colore …
WiSHFUL : enabling coordination solutions for managing heterogeneous wireless networks
2017
The paradigm shift toward the Internet of Things results in an increasing number of wireless applications being deployed. Since many of these applications contend for the same physical medium (i.e., the unlicensed ISM bands), there is a clear need for beyond-state-of-the-art solutions that coordinate medium access across heterogeneous wireless networks. Such solutions demand fine-grained control of each device and technology, which currently requires a substantial amount of effort given that the control APIs are different on each hardware platform, technology, and operating system. In this article an open architecture is proposed that overcomes this hurdle by providing unified programming i…
Identifying motives underlying wine purchase decisions: Results from an exploratory free listing task with Burgundy wine consumers
2014
Abstract To better understand consumer decision making processes while purchasing wine it is important to identify which attributes consumers actually rely on and how they perceive and weight them in order to reach a final decision. The aims of the present work were to identify motives underlying wine purchase decisions and to identify consumer segments with different drivers of wine purchase. One hundred and twenty seven Burgundy wine consumers were asked to complete a free listing task. Relevance of each category of elicited terms was estimated by Smith's and Cognitive saliency indices. Hierarchical cluster analysis was performed on individual Smith's saliency indices. In the free listing…
INNOVAZIONE DEI MATERIALI NATURALI: TERRA E NANOTUBI DI ARGILLA PER UNA SFIDA SOSTENIBILE
2019
All’interno del dibattito culturale che vede la questione ambientale come prioritaria e con riferimento a studi e ricerche che negli ultimi anni hanno promosso materiali compositi a base di terra cruda, gli Autori, consapevoli della necessità che il rapporto fra Progetto e Materia debba assumere una nuova centralità supportato dalle specificità della Tecnologia dell’Architettura, illustrano le risultanze di una sperimentazione che ha l’obiettivo di migliorare le prestazioni della terra cruda con l’apporto delle nanotecnologie, sviluppando un ‘nuovo materiale’ con una ridotta embodied energy e una ridotta quantità di emissioni di CO2 in atmosfera.
Gráficos interactivos y la nueva metodología docente en el EEES
2010
En este artículo mostramos la posibilidad de utilizar los gráficos interactivos disponibles en Internet para la docencia en la universidad acorde con la nueva metodología docente que implica la convergencia de España hacia el Espacio Europeo de Educación Superior. Mostramos un ejemplo concreto de utilización de esta tecnología en la enseñanza de Microeconomía en la Universidad. En particular explicaremos la noción de Equilibrio Walrasiano en el caso de una economía sencilla de intercambio simple representable en la caja de Edgeworth mediante el gráfico interactivo: Walrasian Equilibrium or Disequilibrium.
ACQUISITION OF STUDENT SCIENTIFIC INQUIRY SKILLS: CENTRALISED EXAMINATION RESULTS IN CHEMISTRY
2016
From 2011, the new educational standard in Latvia in the framework of the educational reform on the centralised examination (CE) in chemistry stipulates students to demonstrate the inquiry skills they have mastered. The purpose of this study is to find out the students’ inquiry skills by analysing the CE results in chemistry. This study addresses the following research questions: (a) To what extent are the centralised examination inquiry skills measured according to the standard outcomes? (b) What information on how students have mastered the inquiry skills in chemistry is available from the CE results for the period of 2011-2015? (c) Does measuring the inquiry skills using inquiry-based la…
