La enseñanza no reglada: competencias educativas e influencias sociales

[ES] Las bases educativas de la labor docente han estado sustentadas en los centros de enseñanza reglada (colegios, institutos y/o universidades). No obstante, debido a la gran influencia social y al margen de aprendizaje, la presencia de ámbitos de enseñanza no reglada comienza a prevalecer. El proyecto didáctico reflejado en este artículo ha sido realizado mediante la recogida de datos en diversas academias. Para ello, se ha preparado una entrevista previa a la recogida de los datos de carácter informativo y se ha procedido a la recopilación estadística de dichos datos obtenidos. En definitiva, el artículo pretende estudiar, a través de la práctica, la diversidad educativa y social de la actualidad. [EN] Teaching educational foundations have been supported in formal education centers (schools, high schools and/or universities). Nevertheless, apart from this style of learning, nowadays non-formal education is taking a more relevant role, due to an important social influence. The didactic project presented in this article has been elaborated taking as a frame of reference the data collection obtained from several academies. For this purpose, an interview prior to the collection of informative data has been prepared in order to compile all those statistical data. In conclusion, this article aims to study, through practice, the educational and social diversity of today.

Planktonic potential CO2 emission calculation: preliminary results by applying an adapted enzymatic methodology to marine ecosystems

[EN]Isocitrate Dehydrogenase (IDH) is a key enzyme in the Krebs cycle, being responsible for the production of one of the three CO2 molecules related to cellular respiration. In order to measure the potential CO2 production linked to the marine planktonic community we have adapted an enzymatic methodology. Preliminary results show that different proportions of autotrophs, heterotrophs and mixotrophs and their metabolic pathways, lead to different relationships between potential CO2 emission and potential O2 consumption during cellular respiration. Although more experiments need to be made, this methodology is leading to a better understanding of cellular respiration in marine samples and their impact on the food chain, vertical Carbon flux and the current sequestering capacity for anthropogenic CO2.

Upwelling in the Eastern Subtropical North Atlantic Ocean

[EN]Coastal upwelling in the eastern margin and offshore curl-driven upwelling in the southeastern margin, make the subtropical Northeast Atlantic a region of major primary productivity. When examining a broad zonal area, from the coast to 40_W, we find that the upward transport of nutrients due to offshore curl-driven upwelling becomes the main control on productivity. Nevertheless, despite its relatively small zonal extension of about 100 km, coastal upwelling extends its impact towards the open ocean through offshore Ekman transport and convergence of the meridional flow at Cape Blanc (21_N).
