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…
Resuscitative endovascular balloon occlusion of the aorta (REBOA) in patients with major trauma and uncontrolled haemorrhagic shock: a systematic rev…
2021
AbstractBackgroundMultiple studies regarding the use of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in patients with non-compressible torso injuries and uncontrolled haemorrhagic shock were recently published. To date, the clinical evidence of the efficacy of REBOA is still debated. We aimed to conduct a systematic review assessing the clinical efficacy and safety of REBOA in patients with major trauma and uncontrolled haemorrhagic shock.MethodsWe systematically searched MEDLINE (PubMed), EMBASE and CENTRAL up to June 2020. All randomized controlled trials and observational studies that investigated the use of REBOA compared to resuscitative thoracotomy (RT) with/witho…
Sammenhengen mellom mestringsforventning, helserelatert livskvalitet og selvrapportert fysisk aktivitet blant elever i videregående skole
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Background: Two different intervention models were developed to increase participation in physical education in high school, targeting “motion enjoyment” and “sport enjoyment”. Both models are intended to increase the pleasure of physical activity in physical education, as well as to contribute to the development of students’ skills, abilities and increase future commitment. The intention behind the motion enjoyment model is to reinforce positive experiences which are related to physical activity, along with raising the awareness in young people of the health benefits associated with physical activity. The sport enjoyment model …
Uni ja kardiometabolia : vaihdevuosi-ikäisten naisten unen laadun yhteys sokeri- ja rasva-aineenvaihduntaan ja leptiinitasoihin
2017
Unen laatu heikkenee vaihdevuosien aikana. Heikentynyt unen laatu on yhteydessä sokeri- ja rasva-aineenvaihdunnan häiriöihin. Tämän pro gradu-tutkielman tarkoituksena oli selvittää vaihdevuosi-ikäisten naisten unen laadun yhteyttä kardiometabolisiin riskitekijöihin. Tutkielma perustuu Estrogeeni, vaihdevuodet ja toimintakyky (ERMA) -tutkimuksen aineistoon. Osallistujat poimittiin satunnaisotannalla väestörekisteristä Jyväskylän ja sen lähikuntien 47–54 -vuotiaista naisista (n=6886). Mukaan valittiin ne sisäänottokriteerit täyttävät naiset, jotka vastasivat tutkimuksen alkumittauskyselyyn ja joilta terveydentilaa selvittävän haastattelun sekä laboratoriomittausten jälkeen saatiin luotettavas…
Równość i solidarność w powszechnym ubezpieczeniu zdrowotnym na tle zmian w finansowaniu opieki zdrowotnej od dnia 1 stycznia 2022 r
2022
Równość i solidarność to wartości, które w powszechnym ubezpieczeniu zdrowotnym przybierają postać zasad prawnych mających umocowanie zarówno w konstytucyjnej dyrektywie równego, bez względu na sytuację materialną obywatela, dostępu do świadczeń opieki zdrowotnej finansowanych ze środków publicznych (art. 68 ust. 2 Konstytucji RP), jak i ustawowym postanowieniu, że ubezpieczenie zdrowotne opiera się na zasadzie równego traktowania i solidarności społecznej (art. 65 pkt 1 ustawy o świadczeniach opieki zdrowotnej finansowanych ze środków publicznych). Relacja obu tych zasad w ramach powszechnego ubezpieczenia zdrowotnego polega na tym, że wiele istniejących odstępstw od równego traktowania uz…
Ocena mikrobiologiczna niepasteryzowanych soków owocowych i warzywnych
2017
Celem pracy była ocena parametrów fizykochemicznych oraz mikrobiologicznych niepasteryzowanych soków owocowych i warzywnych podczas próby przechowalniczej. Analizie poddano takie parametry fizykochemiczne, jak: pH, kwasowość ogólną, gęstość względną oraz zawartość ekstraktu. W badaniach mikrobiologicznych określono ilość mikroorganizmów oraz przeprowadzono ocenę jakościową badanych soków. Przetrzymywanie otwartych soków przez jedną godzinę w temperaturze pokojowej nie wpłynęło istotnie na zmianę parametrów fizykochemicznych. W trakcie badań odnotowano wzrost ogólnej liczby drobnoustrojów, stwierdzono obecność bakterii grupy coli oraz bakterii rodzaju Pseudomonas. Nie stwierdzono obecności S…
Real-world experience with obeticholic acid in patients with primary biliary cholangitis
2021
Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…

The drivers of customer satisfaction for academic library services: managerial hints from an empirical study on two Italian university libraries usin…
2015
The intent of this qualitative research is to investigate and understand the requisites of customer satisfaction for academic libraries’ users and to give managerial hints for the implementation of user centred academic library services. To this aim, we analyse the library services of two Italian Universities (the Faculty of Economics of University of Palermo and the Central Library of the University of Salerno) to find relations and congruencies and to evaluate the perceived relevance of the tangible and intangible aspects of these services. In the preliminary phase of the research, we conducted both focus groups and individual interviews involving students or researchers who regularly use…
