Evaluación de competencias en redacción científica tras dos modalidades diferentes de cursos de formación: protocolo del Estudio SCRIU-B
2021
La redacción de artículos científicos es una de las competencias necesarias y solicitadas por los profesionales de la salud. Existen distintos formatos de cursos para adquirirlas, pero no siempre se evalúa objetivamente su impacto. Con un diseño experimental abierto y no aleatorizado, el estudio SCRIU-B pretende evaluar la adquisición de competencias en redacción científica tras la realización de cursos de formación específicos (presenciales y en línea), así como la satisfacción de los participantes. Se incluye un grupo control con alumnado de otras actividades formativas no relacionadas con la escritura científica. Mediante distintos cuestionarios de evaluación de conocimientos, actitudes …
SECONDARY SCHOOL AND UNIVERSITY STUDENTS’ INTEREST IN SCIENCE SUBJECTS IN CONNECTION TO THE CHOICE OF PROFESSION
2019
One of the most important factors influencing the welfare of the society is the development of science and technology, which in turn depends on scientists and students' science literacy. The aim of the study was to investigate the interest of high school and university students in science subjects, their views on factors that raise interest in subjects and play a determining role in the choice of profession. The questionnaire of Riga secondary school and university students about their interest in science subjects in connection to the choice of their profession was carried out. The results of the survey showed that the majority of university students are interested, or they have moderate i…
QUALITY OF INCLUSIVE EDUCATION, OBSTACLES AND NECESSARY PEDAGOGICAL SOLUTIONS IN WORKING WITH PUPILS WITH AUTISM IN ITALY
2018
Nowadays are increasingly encountered children diagnosed with autism, but there are still serious problems of inclusion of these children in the comprehensive general education system. This is due to various factors. The author of this study many years is working in the schools of special education in Rome, so in the year 2010 started research on inclusion of pupils with autism into the Italian schools. The idea is to transmit the author's knowledge and experience further in Latvia, where inclusion of such pupils into general education schools is still at an early stage because of a lack of both human resources and financial resources, as well in regard of experience and clear understanding…
New insights into Early Celtic consumption practices: Organic residue analyses of local and imported pottery from Vix-Mont Lassois
2019
The rich Mediterranean imports found in Early Celtic princely sites (7th-5th cent. BC) in Southwestern Germany, Switzerland and Eastern France have long been the focus of archaeological and public interest. Consumption practices, particularly in the context of feasting, played a major role in Early Celtic life and imported ceramic vessels have consequently been interpreted as an attempt by the elite to imitate Mediterranean wine feasting. Here we present the first scientific study carried out to elucidate the use of Mediterranean imports in Early Celtic Central Europe and their local ceramic counterparts through organic residue analyses of 99 vessels from Vix-Mont Lassois, a key Early Celti…
Nitrogen recovery using a membrane contactor: Modelling nitrogen and pH evolution
2020
[EN] A hollow fibre membrane contactor has been applied for nitrogen recovery from anaerobic digestion supernatant at different operating conditions obtaining nitrogen recovery efficiencies over 99 %. A mathematical model able to represent the time evolution of pH and nitrogen concentration during the recovery process is presented in this paper. The developed model accurately reproduced the results obtained in 26 experiments carried out at different pH values (from 9 to 11), temperatures (from 25 to 35 degrees C), membrane surfaces (from 1.2 to 2.4 m(2)) and feed flow rates (from 0.33 x 10(-5) to 5.83 x 10(-5) m(3)/s) predicting the variations in nitrogen recovery rates measured at the diff…
A post-synthetic approach triggers selective and reversible sulphur dioxide adsorption on a metal-organic framework.
2018
We report the application of a post-synthetic solid-state cation-exchange process to afford a novel 3D MOF with hydrated barium cations hosted at pores able to trigger selective and reversible SO2 adsorption. Computational modelling supports the full reversibility of the adsorption process on the basis of weak supramolecular interactions between SO2 and coordinated water molecules.
Special applications of reverse electrodialysis
2016
Reverse electrodialysis (RED) is a process for direct electricity production from salinity gradients, based on the use of suitable exchange membranes. To develop the RED process on an applicative scale and to add value to the overall process, a key role is entrusted to the selection of electrodic system, redox species, and electrode materials. In particular, it was shown that a proper selection of redox processes allows the use of a RED cell for the wastewater treatment of organic and inorganic pollutants resistant to conventional biological methods and for the synthesis of chemicals without energy supply. The utilization of microbial reverse electrodialysis cells was also proposed to incre…
Mapping of Chagas disease research: analysis of publications in the period between 1940 and 2009
2011
INTRODUCTION: Publications are often used as a measure of success in research work. Chagas disease occurs in Central and Southern America. However, during the past years, the disease has been occurring outside Latin America due to migration from endemic zones. This article describes a bibliometric review of the literature on Chagas disease research indexed in PubMed during a 70-year period. METHODS: Medline was used via the PubMed online service of the U.S. National Library of Medicine from 1940 to 2009. The search strategy was: Chagas disease [MeSH] OR Trypanosoma cruzi [MeSH]. RESULTS: A total of 13,989 references were retrieved. The number of publications increased steadily over time fro…
Proceedings of the first international summit on intestinal anastomotic leak, Chicago, Illinois, October 4-5, 2012
2014
Item does not contain fulltext OBJECTIVE: The first international summit on anastomotic leak was held in Chicago in October, 2012 to assess current knowledge in the field and develop novel lines of inquiry. The following report is a summary of the proceedings with commentaries and future prospects for clinical trials and laboratory investigations. BACKGROUND: Anastomotic leakage remains a devastating problem for the patient, and a continuing challenge to the surgeon operating on high-risk areas of the gastrointestinal tract such as the esophagus and rectum. Despite the traditional wisdom that anastomotic leak is because of technique, evidence to support this is weak-to-non-existent. Outcome…
Evolution of coauthorship networks: worldwide scientific production on leishmaniasis.
2013
Introduction Collaboration is one of the defining features of contemporary scientific research, and it is particularly important with regard to neglected diseases that primarily affect developing countries. Methods The present study has identified publications on leishmaniasis in the Medline database from 1945 to 2010, analyzing them according to bibliometric indicators and statistics from social network analysis. Examining aspects such as scientific production, diachronic evolution, and collaboration and configuration of the research groups in the field, we have considered the different types of Leishmania studied and the institutional affiliation and nationality of the authors. Results Se…
