Terapia trans-cranica ad ultrasuoni focalizzati guidati da Risonanza Magnetica (tcMRgFUS) utilizzando un sistema integrato con uno scanner RM da 1.5T…
2018
Scopo Negli ultimi anni la terapia transcranica ad ultrasuoni focalizzati guidati da risonanza magnetica (tcMRgFUS) per il trattamento di disordini neurologici quali il tremore essenziale (ET) e il Parkinson tremorigeno (PD) è stata effettuata utilizzando esclusivamente scanner RM da 3T. Presentiamo i risultati ottenuti con il primo sistema tcMRgFUS mai integrato con uno scanner RM da 1.5T. Materiali e metodi 23 pazienti (19 ET; 4 PD) sono stati selezionati per essere sottoposti a tcMRgFUS (talamotomia monolaterale; target: nucleo ventrale intermedio, VIM). I pazienti arruolati sono stati valutati prima del trattamento e 2 giorni dopo. L'efficacia del trattamento è stata valutata utilizzand…
TRANSCRANIAL MAGNETIC RESONANCE-GUIDED FOCUSED ULTRASOUND (TCMRGFUS) CON SCANNER DA 1.5T: NOTA TECNICA
2018
Scopo La terapia dei disordini neurologici mediante tcMRgFUS è stata effettuata utilizzando esclusivamente scanner RM da 3T. Utilizzando uno scanner RM da 1.5T la qualità delle sequenze morfologiche utilizzabili per la pianificazione di questi trattamenti è risultata essere soddisfacente utilizzando la bobina body RF (quella utilizzata con scanner 3T). Tuttavia l'SNR delle sequenze utilizzate per la termometria RM è risultato inferiore allo standard accettabile per i trattamenti. È stata quindi sviluppata una bobina a 2 canali per assicurare un adeguato SNR. Presentiamo il protocollo di imaging efficacemente utilizzato per eseguire procedure tcMRgFUS con il primo sistema mai integrato …
Effects of UV Radiation and Diet on Polyunsaturated Fatty Acids in the Skin, Ocular Tissue and Dorsal Muscle of Atlantic Salmon (Salmo salar) Held in…
2010
Article published in Photochemistry and Photobiology, 86 (4): 909-919 JUL-AUG 2010 The effect of UV radiation (UVR) on juvenile Atlantic salmon (Salmo salar) was assessed by measuring the fatty acid (FA) profiles of muscle, dorsal and ventral skin, and ocular tissues following 4-month long exposures to four different UVR treatments in outdoor rearing tanks. Fish were fed two different diets (Anchovy- and Herring-oil based) that differed in polyunsaturated fatty acid (PUFA) concentrations. Anchovy-fed salmon had higher concentrations of ALA (alpha-linoleic acid; 18:3n-3), EPA (eicosapentaenoic acid; 20:5n-3) and DPA (docosapentaenoic acid, 22:5n-3) in their muscle tissues than fish fed the H…

MSNA dal Sud al Nord Italia. Prassi e modelli di inserimento scolastico-formativo
2020
Gli alunni stranieri non accompagnati costituiscono un universo eterogeneo che rappresenta una sfida per la governante dei processi formativi. Da qui la scelta di offrire uno spaccato sull'inserimento formativo dei MSNA nei contesti locali, attraverso una ricognizione delle rilevazioni svolte in realtà del Nord, Centro e Sud Italia. Unaccompanied foreign pupils constitute a heterogeneous universe which represents a challenge for the governing of educational processes. Hence the choice to offer an insight into the training insertion of MSNA in local contexts, through a survey of the surveys carried out in reality in Northern, Central and Southern Italy.
Compensation of Nonlinearity of Voltage and Current Instrument Transformers
2019
This paper aims at characterizing and improving the metrological performances of current and voltage instrument transformers (CTs and VTs) in harmonic measurements in the power system. A theoretical analysis is carried out to demonstrate that, due to the iron core nonlinearity, CT and VT output signal is distorted even when the input signal is a pure sine wave. Starting from this analysis, a new method for CT and VT characterization and compensation is proposed. In a first step, they are characterized in sinusoidal conditions and the harmonic phasors of the distorted output are measured; in the second step, these phasors are used to compensate the harmonic phasors measured in normal operati…
Deconstruction and hermeneutical space as keys to understanding the rural
2020
The purpose of this article is to complement the existing literature on defining the rural by suggesting a novel approach that makes possible a holistic understanding of the rural. The proposed approach is based on deconstruction of the concept of the rural and on hermeneutical philosophy. The current approaches applied in rural studies are evaluated through the lens of holistic understanding, and solutions to the observed problems are discussed. The problems of current rural studies stem from inadequate conceptualization and biased social theory. The conceptual problems can be alleviated, firstly, by understanding the concept of space not only literally but also figuratively. Secondly, the…
Exploring dark creativity: the role of power in an unethical marketing task
2020
Creativity is seen as a significant driver for successful marketing activities. However, little attention is paid to its shady side and little research on the prerequisites for unethical behaviour of marketing experts and executives is on hand. In our experimental study, we examine the mutual influence of power, honesty-humility, and benevolent creativity as predictors for ‘dark creativity’ (the use of creative ideas for malevolent actions). Participants (N = 387) were randomly assigned to a high vs. low power condition (role of marketing director vs. marketing intern). Dark creativity was correlated to benevolent creativity, power motive, and honesty-humility, but did not depend on the pow…
Er det forskjell i barns inntak av frukt og grønnsaker og drikke ved 12, 24 eller 48 måneders alder mellom barn av mødre som har deltatt eller ikke d…

Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2019 Background: Women's intake of fruits and vegetables and drinks during pregnancy can affect both mother and child health.Aim: The purpose of this study is to investigate whether the dietary intervention in pregnant women in the Fit for Delivery study has had an effect on what their child is eating and drinking at 12, 24 and 48 months of age.Method: Pregnant women were recruited up to week 20 of pregnancy and were randomized to either a control or intervention group. Participants responded to food frequencyquestionnaires at different time points. Independent sample t-tests were used to analyze the difference in intake of fru…
