Determination of the atmospheric precipitation pH value on the basis of the analysis of lichen cationoactive layer constitution
2006
Studies of equilibria and kinetics of the ion exchange process between the surrounding (water solution) and lichens prove that the number of mobile hydrogen ions bonded in lichens depends on the concentration of hydrogen ions in the precipitation with which the lichens are in contact and the type and concentration of other cations contained in the precipitation. The measurement of these values was suggested; as a result, it enabled to determine the pH of precipitation by determination of mobile cations bonded in exposed or naturally grown lichens. The studies were conducted on Hypogymnia physodes lichens.

The Challenges of the Schengen Area
2016
After focusing on the Euro crisis, European leaders are now struggling with the biggest migrant crisis since Second World War. Up to now, over 1.1 million migrants have requested protection in Europe, and their number is growing every day. The functioning of the Schengen area is in danger due to control deficiencies at external borders. As it’s facing this challenge, the EU is constantly seeking solutions designed to restore the proper functioning of the system and prevent its collapse.
Nuevas claves para la lectura de Cornelia Bororquia (1801)
2003
En los últimos años del siglo XVIII y principios del siglo XIX la vigencia del pensamiento éclairé fomenta un clima favorable a la supresión del Santo Oficio; la censura del Santo Tribunal es el eje central de Cornelia Bororquia o la víctima de la Inquisición (1801), novela del ex-trinitario Luis Gutiérrez que narra la indefensión de una muchacha en las cárceles de la Inquisición. La novela argumenta en favor de la tolerancia religiosa y en la línea de un cristianismo ilustrado, pero no alcanza el tono radical de otros españoles expatriados. Mientras que el exilio de José Marchena radicaliza su discurso político y su sueño de una sociedad sin clases, la vía de Luis Gutiérrez es más reformad…
All-Possible-Couplings Approach to Measuring Probabilistic Context.
2013
From behavioral sciences to biology to quantum mechanics, one encounters situations where (i) a system outputs several random variables in response to several inputs, (ii) for each of these responses only some of the inputs may "directly" influence them, but (iii) other inputs provide a "context" for this response by influencing its probabilistic relations to other responses. These contextual influences are very different, say, in classical kinetic theory and in the entanglement paradigm of quantum mechanics, which are traditionally interpreted as representing different forms of physical determinism. One can mathematically construct systems with other types of contextuality, whether or not …

Kitchen chemistry course for chemistry education students: influences on chemistry teaching and teacher education – a multiple case study
2019
AbstractThis study introduces the Kitchen Chemistry (KC) course and its influences on chemistry education as a whole. KC is considered to be a life-relevant learning environment that engages learners in science through the pursuit of personally relevant and meaningful goals. KC, as a form of interdisciplinary learning, aims to develop boundary-crossing skills and to support the development of pupils’ scientific thinking. The purpose of this research was to determine how KC as a context-based teaching approach applies to chemistry education and what it offers to chemistry teaching and teacher education. We found that KC gave lower secondary school pupils the opportunity to understand the che…
