Explicit proton transfer in classical molecular dynamics simulations.
2014
We present Hydrogen Dynamics (HYDYN), a method that allows explicit proton transfer in classical force field molecular dynamics simulations at thermodynamic equilibrium. HYDYN reproduces the characteristic properties of the excess proton in water, from the special pair dance, to the continuous fluctuation between the limiting Eigen and Zundel complexes, and the water reorientation beyond the first solvation layer. Advantages of HYDYN with respect to existing methods are computational efficiency, microscopic reversibility, and easy parameterization for any force field peerReviewed
Educación Geográfica y las salidas de campo como estrategia didáctica: un estudio comparativo desde el Geoforo Iberoamericano
2016
Las salidas de campo integran algunas de las principales estrategias didácticas y prácticas pedagógicas utilizadas por profesores de diferentes disciplinas escolares. En la Geografía, numerosas publicaciones académicas y experiencias de enseñanza han sido divulgadas en eventos científicos, artículos y libros. Haremos aquí un estudio de cómo las salidas de campo o visitas de estudio han sido abordadas en la educación geográfica en los países ibero-americanos, en especial en los estudios realizados en Brasil y España. El objeto que queremos abordar en este estudio tiene como núcleo básico el Foro 21, realizado en el Geoforo Iberoamericano, iniciado en febrero de 2015. En él se discutían las s…
Ensuring the comparability of cross-national survey data on intimate partner violence against women: a cross-sectional, population-based study in the…
2020
Objectives To ensure the cross-national comparability of the set of questions addressing physical and sexual intimate partner violence against women (IPVAW) included in the European Union (EU) Agency for Fundamental Rights (FRA) survey. Once the measurement invariance of these measures is established, we aim to make appropriate and valid comparisons of the levels of physical and sexual IPVAW across the EU countries. Design Cross-sectional, population-based study. Participants Data were drawn from the survey conducted by the FRA on violence against women, including the responses of 42 002 adult women from the 28 countries of the EU. Main outcome measures The set of questions addressing lifet…
The Fear of Covid-19 Scale (FCV-19S) in Spain: Adaptation and Confirmatory Evidence of Construct and Concurrent Validity
2021
Fear of the coronavirus has important implications on mental health. In western countries, a significant degree of vaccination has been achieved, but in Spain, less than 75% of the population has received both doses. The current situation is still seen as a threat by many people. Therefore, it is important to have reliable and valid measurement instruments to assess the impact of COVID-19 on the population. In this study, the Fear of COVID-19 Scale has been adapted to Spain, and its psychometric properties have been studied in a Spanish sample using Structural Equation Modeling. This methodology allows obtaining more reliable estimates, regardless of the measurement scale of the variables. …
Do the Mega and Titan Tests Yield Accurate Results? An Investigation into Two Experimental Intelligence Tests
2020
The Mega and Titan Tests were designed by Ronald K. Hoeflin to make fine distinctions in the intellectual stratosphere. The Mega Test purported to measure above-average adult IQ up to and including scores with a rarity of one in a million of the general population. The Titan Test was billed as being even more difficult than the Mega Test. In this article, these claims are subjected to scrutiny. Both tests are renormed using the normal curve of distribution. It is found that the Mega Test has a higher ceiling and a lower floor than the Titan Test. While the Mega Test may thus seem preferable as a psychometric instrument, it is somewhat marred by a number of easy items in its verbal section. …
Public Libraries – Facilitators of Information Society and e- Inclusion in Latvia
2014
Abstract The economic growth and national competitiveness is closely correlated with the development of information society. In the last few years the role of public libraries has significantly increased and libraries have greatly contributed to the improvement of information society in Latvia. The usage of library services had never been as high as they were in 2011 – 42% of the population were active library users and 90% of them used the Internet. Nowadays, the public library network in Latvia provides a powerful network of information, knowledge and community centres and they are highly demanded by society.
Metsästyksen kentän logiikka ja kulttuurinen kestävyys
2017
Metsästyskulttuuri on muutoksessa maaseudun rakenteellisen murroksen myötä. Muutos sisältää jännitteitä, jotka liittyvät yhtäältä metsästyskulttuurin säilyttämiseen ja toisaalta uusien toimijoiden ja käytäntöjen omaksumiseen paikallisyhteisöissä. Metsästysseurat ovat avainroolissa uusien metsästäjien rekrytoinnissa. Artikkelissa tarkastellaan metsästysseurojen jäseneksi ottoa ja ulossulkemisen logiikkaa Pierre Bourdieun kenttäteorian avulla. Metsästäjien haastattelut valottavat metsästysseurojen paikallisia käytäntöjä. Metsästysseuran jäsenyyden saaminen perustuu sosiaaliseen vaihtoon, joka noudattaa sosiaalisen tunnistamisen ja arvonannon logiikkaa. Jäsenyys edellyttää pääomia, joiden arvo…
ELECTRICAL DISCHARGE MACHINING - A HIGH FUTURE NONCONVENTIONAL PROCESSING PROCESS
2021
Electrical discharge machining is one of the most common processes for processing metallic materials. This process is characterized by the lack of mechanical pressure on the object that ensures the macroscopic location of the erosive agent. This scientific paper highlights a study based on experimental data processing as well as modeling the most important technological parameters for dimensional processing by electrical discharge machining with and without magnetic activation. In this context, the modeling and optimization of process parameters is approached, which can lead to the quality increasing of the processed surface, to an increase of the processing productivity and to a reduction …
Nanorings driven by a laser field
2013
We present the dynamics of an electron constrained over an 1D ring with radius of 0.142 nm driven by a laser field. The temporal evolution of the system is evaluated by a semi-analytical solution of the full quantum time dependent Schr¨odinger equation. In our calculation the gap energy between the ground and the first excited state of the nanoring is three times the photon energy laser (0.63 eV) and the laser intensity is 4·1014 W/cm2 . Our analysis is performed by considering different polarization states of the incident laser. Our attention is mainly focused on the study of the High Harmonic Generation (HHG), the energy and the angular momentum absorbed by the driven system. We observe 1…
