A NEW TOOL FOR THE STUDY OF RESONANCE IN CHEMICAL EDUCATION

2014

The objective of this study is to present a computer-based project, for which our program POLAR and our version of PAPID were written for the study of the subject of resonance in chemistry. Both algorithms allow a better didactic strategy and methodological adaptation for the study of molecular properties in chemical education. Teachers will find the options of POLAR and PAPID useful for demonstrations. It is still to be explored the methodological application of these computational programs enriching the present teaching techniques. Implementing new algorithms in learning situations is technically simple, but checking their usefulness in teaching practice is extraordinarily complex and req…

Quality of autochthonous Sicilian plums

2015

Thirty four plum local varieties and accessions obtained from different growing area of the Sicilian island were analyzed for their qualitative and nutraceutical properties and three commercialcultivar were used as references. These properties included the fruit fresh weight (g), the pulp firmness (FFF), the total soluble solids (TSS), the titratable acidity (TA), the total anthocyanins,the phenolics content and the antioxidant activity.This preliminary study showed significantly differeces among the plums; Zuccarato giallo and Prunu Niuru presented TSS higher than the commercial cultivars (24.9 and 21.6 °Brix respectively)and interesting data obtained on the nutraceutical compounds values …

Life events and primary monosymptomatic nocturnal enuresis: A pediatric pilot study

2017

Introduction: The association between primary monosymptomatic nocturnal enuresis (PMNE) and behavioral disorders was highlighted frequently, suggesting psychiatric origin. On the other hand, there is no difference between the incidence of mental disorders in children with PMNE and controls, although the psychological genesis could provide additional secondary forms, in which the child might react to stressful events with the resumption of involuntary urination at night, with a possible alteration of bowel control due to a high vulnerability to stressors. The purpose of this study is assessing the stressful events of life in a sample of children with PMNE. Materials and methods: 56 subjects …

Modelling of rotations by using matrix solutions of nonlinear wave equations

2007

A family of matrix solutions of nonlinear wave equations is extended and its application to modelling is given. It is shown that a similarity transformation, induced by the matrix solution, is equivalent to the rotation. Matrix solutions are used for modelling helical motions and vortex rings, simultaneous rotations and particles collision, mapping contraction and pulsating spheres. Geometrical interpretation of the doubling of rotation angle in each step of sequential mapping contraction is given. First Published Online: 14 Oct 2010

Ver, imaginar, escribir el mar

2014

Como lo han mostrado numerosos poetas y escritores, el mar permanece desde siempre en el imaginario humano y se manifiesta, por medio de imágenes simbólicas, tanto en los textos narrativos o poéticos, como en las más diversas creaciones artísticas. Según las épocas y las corrientes literarias e las mutaciones del pensamiento humano, debidas a factores múltiples (coyunturales, históricos, sociales, etc.)presenta unas caracterizaciones que reflejan el estado de ánimo del individuo y su medio cultural. También, como lo demuestran los estudios en el campo de la publicidad y del turismo, el mar ejerce un atractivo innegable en la sociedad contemporánea. Lugar imaginario de nuestros temores y de …

Modeling Political Corruption in Spain

2021

Political corruption is a universal phenomenon. Even though it is a cross-country reality, its level of intensity and the manner of its effect vary worldwide. In Spain, the demonstrated political corruption cases that have been echoed by the media in recent years for their economic, judicial and social significance are merely the tip of the iceberg as regards a problem hidden by many interested parties, plus the shortage of the means to fight against it. This study models and quantifies the population at risk of committing political corruption in Spain by identifying and quantifying the drivers that explain political corruption. Having quantified the problem, the model allows changes to be …

Percepción de la seguridad alimentaria por las familias valencianas

Data from the GIPEyOP online election poll for the 2015 Spanish General election.

2020

Abstract The general elections of 2015 in Spain took place in the middle of the Great Recession after several years of austerity economic policies. This election caused a political earthquake that shook the Spanish party system. During the campaign of that election, GIPEyOP (Elections and Public Opinion Research Group from University of Valencia) conducted a survey to collect relevant data about the electorate beliefs, intentions and motivations. This article describes the data set attained, which comprises 71 variables after removing, to ensure full anonymity, those variables that would potentially allow respondents to be identified. Respondents answered a self-administered online question…
