Children left unattended in vehicles in Italy: look behind you before leaving your car
2018
In recent years, the number of children left unattended in parked vehicles is increasing and, according to the Child Abuse and Prevention Treatment Act, this phenomenon can be considered a form of neglect. In addition, the exposure of children to warm environments could cause their death from hyperthermia and heat stroke. Children are more vulnerable than adults to heat for three reasons: children have a high surface area body mass ratio, a less heat dissipation from center of the body to periphery and a less sweat production. In addition, a study was carried out to evaluate the effects of stress on Working Memory, whose alteration could bring a parent to forget his child in the car. In Ita…
Exploring single polarization X-band weather radar potentials for local meteorological and hydrological applications
2015
Summary The aim of this study is to evaluate the potential use of a low-cost single polarization X-band weather radar, verified by a disdrometer and a dense rain gauge network, installed as a supporting tool for hydrological applications and for monitoring the urban area of Palermo (Italy). Moreover, this study focuses on studying the temporal variability of the Z–R relation for Mediterranean areas. The radar device is provided with an automatic operational ground-clutter filter developed by the producer. Attention has been paid to the development of blending procedures between radar measurements and other auxiliary instruments and to their suitability for both meteorological and hydrologic…
Modeling Rainfall Erosivity by Measured Drop-Size Distributions
2015
AbstractThe study of the detachment of soil particles due to rainfall erosivity requires knowledge of the energetic characteristics of the precipitation. In this paper, following a review of both the drop-size distribution (DSD) proposed by one researcher and the corresponding relationship for evaluating the kinetic power of rainfall, the reliability of that researcher’s DSD using the size distributions of raindrops detected by an optical disdrometer installed at Palermo (Sicily) is experimentally tested. Finally, an experimental verification of both the relationship proposed by two separate research teams for evaluating the specific and unit rainfall kinetic energy is carried out.

Expresión de aquaporinas 1 y 5 en el pulmón de ratas sometidas a ventilación mecánica: efectos del volumen corriente y el tiempo de ventilación
2015
El daño pulmonar inducido por la ventilación mecánica (VM) desempeña un papel clave en el desarrollo y evolución del síndrome de distrés respiratorio agudo. Las aquaporinas (AQPs), una familia de proteínas de canal transmembrana, permiten el movimiento bidireccional de agua de forma rápida y selectiva. De estas, se conocen por lo menos 13 tipos diferentes que se expresan en mamíferos de los cuales el pulmón expresa cuatro. Su papel en el desarrollo y la resolución del edema pulmonar es controvertido, aunque parece que pueden tener un papel en el edema inducido por la ventilación mecánica. Con estos antecedentes y sobre las hipótesis de que la ventilación mecánica aplicada con volúmenes corr…
L’écriture et le graphisme à l’ère de la linguistique psychologique
2016
This study deals with the conception of “writing” within the German humanities during the « psychological turn » of the last half of the XIXth - the beginning of the XXth centuries. The focal point is “graphism” and “writing” understood as “expressive movements” (Ausdrucksbewegungen), this notion being bound to the concept of “verbal gesture” within the trend of “psychological linguistics” (1850-1930). Inspired initially by the morphological and physiognomonic tradition (J. Lavater, J. W. Goethe, J. Engel, C. Carus, Th. Piderit), this conception considers language as a particular kind of “expressive movements”. This vision comes back to the German psychology of consciousness elaborated by J…
Characterizing rainfall erosivity by kinetic power-Median volume diameter relationship
2018
Abstract Kinetic power, i.e. kinetic energy per unit time and area, is the variable widely used to represent the rainfall erosivity which affects soil loss and sediment yield. This paper shows the results of an experimental investigation using the raindrop size distributions (DSDs) measured by an optical disdrometer installed at the Department of Agricultural, Food and Forestry Sciences of University of Palermo in Italy (June 2006–March 2014) and at the El Teularet experimental station in Spain (July 2015–May 2016). At first an analysis of the DSDs aggregated into intensity classes is carried out, then the measured kinetic power values are determined. The aggregated DSDs allowed to establis…

CARATTERISTICHE DIMENSIONALI ED ENERGETICHE DI PRECIPITAZIONI NATURALI MISURATE CON UNA TECNICA DISDROMETRICA IN SPAGNA
2016
Nella memoria sono riportati i risultati ottenuti a partire dalle distribuzioni dimensionali delle gocce di pioggia (DSD) rilevate nel periodo Luglio 2015- Gennaio 2016, mediante un disdrometro ottico installato presso la stazione sperimentale “El Teularet- Sierra de Enguera” sita nella comunità Valenciana. Dopo aver aggregato le DSD per classi di intensità, è stata condotta una analisi sulle caratteristiche delle distribuzioni rilevate in funzione dell’intensità di precipitazione ed è stata verificata l’applicabilità della distribuzione di Ulbrich utilizzando il metodo dei momenti per la stima dei parametri. Le misure sono state utilizzate per determinare i valori misurati di potenza cinet…
