Prevalence of the bullying phenomenon in a schools sample of Palermo, Sicily: a pre-post intervention observational study among teachers
2018
Background and aim of the work: Bullying involves a significant percentage of school-age children. According to the latest available surveillance data, in Sicily, the estimated prevalence among 11-15 years old children is 14%. This study aimed to estimate a prevalence of the bullying phenomenon, observed by teachers, in a sample of secondary schools of Palermo, Sicily. Moreover, after the conduction of preventive interventions among teachers, aimed to evaluate any modification in bullying prevalence. Methods: A cluster sampling selection according to socio-economic level of the school neighborhood was carried out. Two anonymous online questionnaires, pre and post-intervention, were administ…
«Antaviana»: del text narratiu al text dramàtic
2015
The author studies the changes taken place in the stories which have given rise to the theatrical play in its passage from the genres of narrative to drama, from narrated history to performed history.
La nova dramatúrgia catalana: de la perplexitat a la diversitat
1997
In the Catalan theatrical world —considered only from the Principat angle— a series of factors defined the continuity and the renovation of the genre occurring between 1975 and 1985, through dramatic works already known years before and the success of new writers. The article establishes a balanced view and lists largely the authors and works of the period.
Market outlook, production chain and technological innovation for Pleurotus nebrodensis mushrooms
2013
This chapter provides a report of a marketing investigation performed in synergy with private companies in order to activate a production chain for the cultivation and trade of Pleurotus nebrodensis. A recent experience of technological innovation carried out in a farm of the Madonie (N. Sicily) territory is also presented. Notes on the status of Critically Endangered species and pertinent legislation are also provided.
Performance of Lead-Acid Batteries with Nanostructured Electrodes at Different Temperature
2018
In this work we present innovative lead-acid batteries with nanostructured electrodes, which are cycled in a wide range of temperatures typically of lead-acid commercial batteries (EN 61427-1: 2013). In comparison to parameters usually used to commercial batteries, much more stressful conditions in terms of cut-off, charge/discharge rate and discharge were imposed.
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
ELECTROCHEMICAL H2O2 SENSORS BASED ON Pd and Cu NANOSTRUCUTERS
2018
In the last decades, with the fast improvement of electronics, the field of sensors is highly expanding. The basic idea of sensors is to detect something and then trigger a corresponding action. This simple, but very important, concept can be used in different fields: from chemical industries to farms, from the environmental monitoring [1] to a point of care analysis [2]. Currently, talking about sensing of chemical species, different techniques are used, such as Atomic Absorption Spectroscopy (AAS), Graphite Furnace Atomic Absorption Spectroscopy (GFAAS), Inductively Coupled Plasma Mass Spectroscopy (ICP-MS), IR spectroscopy, redox titration and so on. Despite they are highly efficient in …

SORVEGLIANZA DELLE COLONIZZAZIONI DA STAPHYLOCOCCUS AUREUS METICILLINO-RESISTENTE E GRAM-NEGATIVI MULTI-RESISTENTI NELLE UNITA’ DI TERAPIA INTENSIVA …
2014
INTRODUZIONE: La diffusione della resistenza batterica, sia in ospedale che in comunità, costituisce un serio motivo di allarme. La disseminazione di microrganismi resistenti in ospedale, particolarmente accentuata in reparti critici quali le terapie intensive, è favorita oltre che dall’uso dei farmaci antimicrobici, da procedure chirurgiche e/o invasive, dalla presenza di pazienti compromessi e dal trasferimento da una struttura sanitaria ad un’altra di pazienti colonizzati o infetti. Una conoscenza dettagliata dell’entità del fenomeno e dei principali microrganismi antibiotico-resistenti in ambito nosocomiale è essenziale per lo sviluppo di strategie volte a prevenire tale fenomeno. In qu…
La terminologia sintàctica bàsica en els manuals d’ensenyament del català i l’espanyol. Una introducció
2015
Aquesta tesi pretén fer un diagnòstic del tractament de la terminologia lingüística utilitzada per referir-se als conceptes sintàctics bàsics en les llengües oficials al territori valencià (català i espanyol) durant el primer cicle de l’etapa d’ESO a partir de l’anàlisi dels manuals escolars. El corpus analitzat està format per una mostra significativa dels llibres de text utilitzats en l’ensenyament de les llengües oficials a les aules valencianes, editats per editorials valencianes o bé per segells valencians d’editorials de fora. Els objectius generals són els següents: analitzar els llibres de text que s’usen a les aules valencianes (estructura, organització i continguts) per tal de sab…
