Sleep Apnea, Sleepiness, and Driving Risk
2019
Obstructive sleep apnea is associated with excessive daytime sleepiness in about 50% of cases, and with increased risk of driving accidents. Treatment with continuous positive airway pressure effectively decreases such risk, but compliance with continuous positive airway pressure treatment is often suboptimal. According to the European Union Directive on driving risk, retention of a driving license in patients with obstructive sleep apnea requires assessment of sleepiness and adherence to continuous positive airway pressure treatment, but there remains uncertainty on the optimal methods to assess sleepiness on a large scale.
Variations in teaching of removable partial dentures in Spanish dental schools
2010
Objectives: Despite the increasing demand for implant-based treatments, removable partial dentures (RPDs) are frequently used in the oral rehabilitation of partially dentate patients. Furthermore, the Bologna Declaration Agreement (1999) promotes the freedom of movement both of students among dental schools and of graduates across the European Union (EU). Given that inconsistency in teaching among dental schools may lead to confusion, this study aimed to evaluate the status of teaching and clinical experience reached by undergrad uate dentalstudents in Spanish dental schools in relation to RPDs. Study design: A questionnaire seeking information on the preclinical and clinical teaching of RP…
Analysis of pesticides in fruits by pressurized liquid extraction and liquid chromatography-ion trap-triple stage mass spectrometry.
2005
A multi-residue method using pressurized liquid extraction (PLE) and liquid chromatography-quadrupole ion trap-triple stage mass spectrometry (LC-IT-MS(3)) has been developed for determining trace levels of pesticides in fruits. The selected pesticides can be distinguished in: benzimidazoles and azoles, organophosphorus, carbamates, neonicotinoids, and acaricides. PLE has been optimized to extract these pesticide residues from oranges and peaches by studying the effect of experimental variables on PLE efficiency. Samples were extracted at high temperature and pressure (75 degrees C and 1500psi) using ethyl acetate as extraction solvent and acidic alumina as drying agent. The recoveries obta…
Financial Intermediation in Modern Europe Time: Evidence from Romania
2018
In a world governed by complex financial and economic systems, knowing the process of financial intermediation becomes a must. We face times when the process of financial intermediation seems to change nearly as a natural phenomenon. Financial intermediation stakeholders find constantly new ways to interact on behalf of obtaining funds they need and returns they expect and manage risks they try to avoid. The article’s aim is to take a snapshot of a financial intermediation process that manifests in Europe Modern Era, specifically in one EU member like Romania, in contrast with other two EU member – Bulgaria and Croatia. In the same time, we also outline the relation between financial develo…
Life Cycle Assessment for Supporting Eco-Design: The Case Study of Sodium–Nickel Chloride Cells
2021
The European Union is moving towards a sustainable, decarbonized, and circular economy. It has identified seven key value chains in which to intervene, with the battery and vehicle value chain being one of them. Thus, actions and strategies for the sustainability of batteries need to be developed. Since Life Cycle Assessment (LCA) is a strategic tool for evaluating environmental sustainability, this paper investigates its application to two configurations of a sodium–nickel chloride cell (planar and tubular), focusing on the active material and the anode, with the purpose of identifying the configuration characterized by the lowest environmental impacts. The results, based on a “from cradle…
Implementation of Content and Language Integrated Learning at Schools in Latvia
2017
The European Union supports multilingualism and promotes the learning of foreign languages since their knowledge enhances understanding among peoples and increases employability. To increase the efficiency and effectiveness of foreign language education in schools, Content and Language Integrated Learning (CLIL) has been promoted in Europe; this has influenced ways in which Latvia nowadays approaches bilingual education. A qualitative case study was undertaken to explore the implementation of CLIL at schools in Latvia, CLIL being seen as an element of bilingual education. This article outlines the development of CLIL in Latvia, which is largely embedded in national level policies which have…
Worldwide research output trends on drinking and driving from 1956 to 2015.
2020
This study seeks to analyze worldwide research activity on drinking and driving of macro-actors (countries and research fields) and meso-actors (institutions, journals, articles, co-substance(s) studied) during the last 6 decades (between 1956 and 2015). Web of Science and Elsevier Scopus were searched using terms referred to drinking and driving, including terms related to vehicles and way spaces. Overlapping was excluded and absence of false positives was confirmed. Articles on alcohol with/without other psychoactive substances were assessed quantitatively (bibliometric measures). Well identified by All Science Journal Classification system (ASJC) (Elsevier Scopus), an increase in the num…
Applying extracellular vesicles based therapeutics in clinical trials - an ISEV position paper.
2015
Extracellular vesicles (EVs), such as exosomes and microvesicles, are released by different cell types and participate in physiological and pathophysiological processes. EVs mediate intercellular communication as cell-derived extracellular signalling organelles that transmit specific information from their cell of origin to their target cells. As a result of these properties, EVs of defined cell types may serve as novel tools for various therapeutic approaches, including (a) anti-tumour therapy, (b) pathogen vaccination, (c) immune-modulatory and regenerative therapies and (d) drug delivery. The translation of EVs into clinical therapies requires the categorization of EV-based therapeutics …

Statistical Learning Algorithms to Forecast the Equity Risk Premium in the European Union
2018
With the explosion of “Big Data”, the application of statistical learning models has become popular in multiple scientific areas as well as in marketing, finance or other business disciplines. Nonetheless, there is not yet an abundant literature that covers the application of these learning algorithms to forecast the equity risk premium. In this paper we investigate whether Classification and Regression Trees (CART) algorithms and several ensemble methods, such as bagging, random forests and boosting, improve traditional parametric models to forecast the equity risk premium. In particular, we work with European Monetary Union data for a period that spans from the EMU foundation at the begin…
