Respiratory mechanics measured by forced oscillations during mechanical ventilation through a tracheal tube
2011
The forced oscillation technique (FOT) allows the measurement of respiratory mechanics in the intensive care setting. The aim of this study was to compare the FOT with a reference method during mechanical ventilation through a tracheal tube. The respiratory impedance spectra were measured by FOT in nine anaesthetized pigs, and resistance and compliance were estimated on the basis of a linear resistance-compliance inertance model. In comparison, resistance and compliance were quantified by the multiple linear regression analysis (LSF) of conventional ventilator waveforms to the equation of motion. The resistance of the sample was found to range from 6 to 21 cmH(2)O s l(-1) and the compliance…
INEQUALITIES AND TOURISM CONSUMPTION BEHAVIOUR: A MIXTURE MODEL ANALYSIS
2015
The criticism of income as a measure of well-being and trends in living standards is well known and recently scholars have been involved in defining measures to better assess material well-being and differences in living standards. Recent evidence shows that individuals improve their well-being significantly if they are able to spend on higher-order goods and services like tourism and leisure activities. In the light of that, our study proposes to explore differences in living standards in Italy by analysing the distribution of tourism expenditure. For this aim, Mixtures of Regression Models were used in order to investigate whether there is an unobserved heterogeneity in tourism consumptio…
Have IFRS Changed How Stock Prices Associate with Earnings and Book Values? Evidence from Norway
2012
Firms listed on European, Australian and an increasing number of other stock exchanges are required to report according to International Financial Reporting Standards (IFRS). We use a Norwegian sample to examine whether the adoption of IFRS in 2005 has changed the value relevance of earnings relative to book values. IFRS are balance sheet-oriented and emphasize measurement at fair value. In contrast, Norwegian GAAP (NGAAP) are earnings-oriented and focus on measurement at transactional (historical) cost. IFRS also differ by recognizing more intangible assets, which further contributes to making IFRS less conservative than NGAAP. We find that more fair value accounting increases the value re…
The European network for care of children with paediatric rheumatic diseases : Care across borders
2019
Objectives. To provide an overview of the paediatric rheumatology (PR) services in Europe, describe current delivery of care and training, set standards for care, identify unmet needs and inform future specialist service provision. Methods. An online survey was developed and presented to national coordinating centres of the Paediatric Rheumatology International Trials Organisation (PRINTO) (country survey) and to individual PR centres (centre and disease surveys) as a part of the European Union (EU) Single Hub and Access point for paediatric Rheumatology in Europe project. The survey contained components covering the organization of PR care, composition of teams, education, health care and …
Chromatographic and mass spectrometric characteristics of 20-dihydroaldosterone.
1992
The 20 alpha-reduced derivative of aldosterone, 20 alpha-dihydroaldosterone, was needed as reference compound in order to continue the studies on 18-hydroxylation in the Y-1 adrenal cell line. It was obtained by reduction of aldosterone with sodium borohydride. Analysis of the products of the reaction as methoxime trimethylsilyl (MO-TMS) derivatives by gas chromatography (GC) and GC-mass spectrometry (GC-MS) showed three possible forms of the compound. Their identification was confirmed by comparison with the products obtained by stereospecific reduction of aldosterone using 3 alpha,20 beta-hydroxysteroid dehydrogenase. Chromatographic behavior and mass spectra are given for the three forms…
Multivariate optimization of the hollow fibre liquid phase microextraction of muscimol in human urine samples.
2016
Abstract A liquid phase microextraction based on hollow fibre followed by liquid chromatographic determination was developed for the extraction and quantitation of the hallucinogenic muscimol from urine samples. Method applicability on polar hallucinogens was also tested on two alkaloids, a psychedelic hallucinogen, tryptamine and a polar amino acid, tryptophan which exists in its charged state in the entire pH range. A multivariate design of experiments was used in which a half fractional factorial approach was applied to screen six factors (donor phase pH, acceptor phase HCl concentration, carrier composition, stirring rate, extraction time and salt content) for their extent of vitality i…
Occurrence of priority pollutants in WWTP effluents and Mediterranean coastal waters of Spain
2011
A comprehensive study aimed at evaluating the occurrence, significance of concentrations and spatial distribution of priority pollutants (PPs) along the Comunidad Valenciana coastal waters (Spain) was carried out in order to fulfil the European Water Framework Directive (WFD). Additionally, PP concentrations were also analysed in the effluent of 28 WWTPs distributed along the studied area. In coastal waters 36 organic pollutants of the 71 analysed, including 26 PPs were detected although many of them with low frequency of occurrence. Only 13 compounds, which belong to four different classes (VOCs, organochlorinated pesticides, phthalates and tributyltin compounds (TBT)) showed a frequency o…
VESICAL IMAGING-REPORTING AND DATA SYSTEM – A NEW APPROACH TO BLADDER CANCER STAGING
2022
The aim: To present the assumptions and to show the usefulness of Vesical Imaging-Reporting and Data System (VI-RADS) based on multiparametric magnetic resonance imaging (mpMRI) in the diagnostic pathway management of patients with a bladder cancer. Materials and methods: The review is based on available literature from last 10 years from PubMed database and the Przegląd Urologiczny journal focusing on articles on VI-RADS. Overall, 18 articles were included. Presented magnetic resonance images come from the examinations of the patients who were diagnosed with bladder cancer from 2019 to 2021 at Department of Diagnostic Imaging in University Clinical Hospital in Opole, Poland. Conclusions: T…
Through the Eyes of an Entangled Teacher: When Classical Musical Instrument Performance Tuition in Higher Education is Subject to Quality Assurance
2020
What happens when a classical music instrument performance course at a Norwegian state university study programme is assessed for quality following a standardized procedure? The article explores frictions and negotiations between managerial quality assurance and classical music performance education in a contextual sense, focusing particularly on the teacher-student relation. I employ my own experience as an instrument performance teacher in a Western Classical Music performance study programme while drawing on state acts, regulations, managerial processes, educational politics, funding, and classical music performance education’s habitus and heritage. I begin by addressing the institution …
Debating Sound Money in Early Modern Europe: From Dualist to Metallic Monetary Systems
2019
International audience; In this paper, we present the monetary debates in Europe from the XVIth to the XVIIIth centuries from the viewpoint of the problem of good and sound money. The framework of the paper is built on a typology of monetary systems, by which a dualist system is distinguished from a metallic one. Under the dualist system, the value in units of account of the specie in circulation was defined by monetary proclamations (Einaudi locates this era from Charlemagne to the French Revolution). Metallist proponents aimed at preventing any kind of manipulations with a radical transformation of the system of payment, which gave birth to a metallic monetary system from the very end of …
