Simplification of Models
2016
In practical applications the “complete” model, i.e., a model that contains all features that the experts in the application domain consider important, is often quite complicated and difficult to analyse mathematically. A straightforward numerical realization is often costly and may give very little qualitative understanding of the situation. It is therefore important to study if the model can be systematically simplified in order to enhance a qualitative analysis/understanding.
La calidad periodística mediante el análisis del discurso de los profesionales de la información
2015
La investigación indaga las opiniones de los periodistas sobre la influencia de los cambios en el campo periodístico en las últimas décadas, es decir, qué opinan los periodistas sobre lo que permanece, lo que ha desaparecido y aquello que es nuevo. La base teórica se fundamenta en la teoría del campo y del habitus de Pierre Bourdieu y en el análisis de la estructura comunicativa desde las perspectivas económica, sociológica, históricopolítica y tecnológica. Se han aplicado una serie de métodos complementarios: análisis cualitativo de entrevistas en profundidad y análisis pragmadialéctico de los argumentos de los periodistas entorno al concepto de calidad periodística The research investigat…

Biologically active properties of plant extracts in cosmetic emulsions
2020
Abstract Describes biologically active properties waters plant extracts of domestic herbaceous species as a part cosmetic emulsion in this article. In particular, the antioxidant features related to vitamins, flavonoids, coloring, extractive and tannins were reported. The following research methods as qualitative analysis on groups of biologically active substances, thin-layer chromatography, titrimetry and photometry were used in the work. The ability of extracts to influence the physico-chemical, organoleptic and antioxidant properties of cosmetic emulsion samples was established. The ability of the extracts to exhibit antioxidant and prooxidant effects in cosmetic emulsion samples was de…
The use of near-infrared spectrometry in the olive oil industry.
2010
The enormous possibilities offered by near-infrared (NIR) spectroscopy for the (on/in/at-line) quality control process of olive fruits, pastes, and oils are summarized throughout this paper. Special attention has been paid to the combination of NIR and chemometric treatments for the on-line analysis of olive fruits and also for the quality parameters evaluation on olive oils and pastes which can enhance the production of a high quality olive oil and the selection of olive fruit with superior properties. The implementation of NIR sensors in olive mills with successful results has also been reviewed and the commercial olive fruit and oil analyzers highlighted.
Quantitative and qualitative analysis of DNA extracted from postmortem muscle tissues
1990
DNA extracted from 33 postmortem muscle specimens was analyzed using MZ 1.3, a hypervariable minisatellite probe, as well as locus-specific minisatellite probes (g3, MS1 and MS43). After storage at -25 degrees C for 10 months, DNA from all the samples was partially (approximately 21% of total DNA) degraded even when autopsy was performed 1 day postmortem. However, more than 90% of DNA samples up to at least 3 days postmortem were suitable to obtain good restriction fragment length polymorphism (RFLP) patterns. When small strips of specimen were stored for 8 days at room temperature in moist chambers, approximately 42% of total DNA was degraded. Only 30% of these DNA samples still showed goo…
Effect of Computer-Aided Navigation Techniques on the Accuracy of Endodontic Access Cavities: A Systematic Review and Meta-Analysis
2021
Simple Summary The endodontic access cavity is an essential step in the root canal treatment allowing the access and location of the root canal system. The inaccuracy during the endodontic access cavitie can lead to intraoperative complications such as missed root canals or root perforations, and hence affect the prognosis of the root canal treatment. The development of computer-aided static and dynamic navigation techniques has improved the accuracy of endodontic access cavities and root canal location; however, it is necessary a comparative analysis to clarify which of the computer-aided navigation system is more accurate. This systematic review and meta-analysis aims to clarify the root …
Prevalence of influenza vaccination among nurses and ancillary workers in Italy: Systematic review and meta analysis
2011
Italian Ministry of Health recommends vaccination for seasonal influenza to all healthcare workers (HCW), particularly to nurses who have an important interaction with patients. The aim of this study is to conduct a systematic review in order to estimate the pooled prevalence of influenza vaccinations among nurses and ancillary workers in Italy and analyze the enhancing and hindering factors. Results: The review was performed using 15 articles, 6 containing the prevalence of vaccination for nurses and ancillary workers, while the others qualitative analysis. In all the selected articles the score calculation has been performed by using a protocol for observational studies. The nurses and an…
Vagueness expressions in Italian, Spanish and English task-oriented dialogues
2017
In this article, we present a corpus-based analysis on the use of Vagueness Expressions (VEs) in Italian, Spanish and English in Task-oriented Dialogues. Following the distinction among informational, relational and discourse vagueness (Voghera 2012), we compare the width of the functional space of the most frequent VEs. In particular we investigate whether and to what extent the VEs cover all the types of vagueness in the three languages. Quantitative and qualitative analysis brings evidence about a high convergence in the vagueness functions expressed by the VEs of the three languages.
LAS MUJERES COMO AGENTES PARA LA COHESIÓN TERRITORIAL DE LOS DESTINOS TURÍSTICOS RURALES
2020
Resumen. Las mujeres rurales, presentes, pero invisibles en los procesos emergentes del medio rural, se revelan como colectivo impulsor para la reconstrucción de los territorios rurales. Este segmento de la población promueve procesos creativos que dinamizan el mundo rural e instrumenta estrategias de diversificación necesarias para sostener la vida y el territorio. Estas estrategias dan lugar a la diversificación de las funciones productivas del territorio y posibilitan la creación de destinos turísticos rurales sostenibles y de enfoque territorial. No obstante, no se muestran modificaciones significativas en la división del trabajo por género. A través de un análisis cualitativo, realizad…
